Biiy, Sunset Beach, Calif., assignor to FMC Corporation, San Jose Calif., a corporation o' Delawvire 9 x Filed Feb. 8, 1962, Ser. No. 171,841 20 Claims. (C]. 137-615) This invention relates to fluid handlin.- equipment, and inore particularly to apparatus for transferring fluid from one fluid handling means to another. 10 An object of the invention is to provide an improved fluid transferrin.- apparatus. Another object is to provide improved and simplified apparatus for temporarily pstablishing fluid conveying interconnection between separate fluid contaiiiers without 15 requirin.- exact spacing between the containers, thereby adapting the -apparatus for use in loadi@ig and unloading fluid carryidg vehicles. Another object is to orovide improved apparatus adapted to maintain efficient fluid conveying comrnunica tion between fluid delivering and fluid receiving condiiits - 20 between which relative motion is apt to occur, thus particularly adapting the apparatus of the itivention for such uses as supplying fuel oil or water to ships, and loading and untoadiiig marine tankers and oil or water 25 carrying barges. Another object of the present invention is to provide improved apparatus for temporarily establishing fluid conveying communication between separatb fluid conduits, such as an oil supply line on a dock and an oil 30 receiving line on a barge, which apparatus is maneuverable to and from operative positions easily, quickly, and without the manhandling or hazards of injury to p.-rsonDel or equipment that cbaracterizes the heavy and cumbersome flexible hoses commonly employed for loading and 35 unloading liquid transporting marine carriers. Another object is to provide a tanker or barge loading and tinloading apparatus including a tubular conduit made up of a plurality of pivotally interconnected rigid tubing sections and so arradged that a lone operator on the 40 dock can quickly and with little effort maneuver the distal end of the conduit to a position so close to a selected conduit on a tanker or bar.-e that they can easily be coupled together. Another object is to provide improved fluid handling 4@5 apparatlis for marine use, iiicluding a plurality of pivotally interconnected rigid tubes ad-,ipted to be mounted on a loading wharf or pier and so supported and operated that when not in use it can be disposed in an elevated position out of the way of traffic. 50 Another object of the invention is to provide an improved fluid handling hose construction including rigid, pivotally interconnected tubin.- sectiods movable optionally to an extended operative position, or to an inoperative retracted position, and including means for cotinter- 55 balancing the movable parts of the apparatus in any position throti.-hout its ftill range of n-iovement. Another object is to provision of a fluid handling apparatus including two rigid, swiveli@y interconnected tubes, each of which is independently n-ianeuverable rela'Lively 60 to the other. Another object of the invention is to provide a liquid cargo handling apparatus iiieluding inboard and outboard tubin.- sections, wherein the inboard section can be swung about a horizontal axis to and from a retracted or idle 65 posit'lon without disturbin.- the attitude of the outboard section, and wherein the outboard section can be swung about a horizontal axis adjacent the free or outer end of the inboard section. Another object is the provision of a miiltisection 70 tubular liqtiid car.-o handling apparatus constituting an 2 improvement over that disclosed in United States Patent No. 2,927,607 issued Mar. 8, 1960 to P. J. Bily. These and other objects and advantages of the present invention wilil become apparent from the following description and the accompanying drawings in which: FIG. 1 is a side elevation of fluid transferring apparatus embodying the invention. FIG. 2 is a rear elevation of the apparatus disclosed in FIG. 1. FIG. 3 is a side elevation of another apparatus embodying the invention. FIG. 4 is a rear elevation of the apparatus disclosed in FIG. 3. FIG. 5 is a side elevation of another apparatus embodying the invention. FlG. 6 is a rear elevation of the apparatus disclosed in FIG. 5. FIG. 7 is a schematic diagram of the hydraulic circuit used in the embodiments disclosed in FIGS. 3 and 5, resp ectively. Each of the illustrated embodiments of the present iivention is a fluid transferring apparatus comprising an articulated tubular conduit A (FIGS. 1, 3 and 5) including rigid inboard and outboard tubes B and C, respectively, arranged substantially in end-to-end relation. The inner section B o' the conduit A is carried by a suitable supportin,@ structure such as a loading or unloadin.- dock D for tank trucks or marine vessels. The inner conduit. section B is pivotally mounted for universal movement about intersecting horizontal and vertical axes adjacent the inner end of the section so that it serves as a supporting boom for the outer conduit section C, which is pivotally connected to the outer end of the inner section B for movement relative thereto in a vertical plane. A pipe or other tubular conduit E is in constant communication with the conduit A to supply fluid thereto or to receive fluid therefrom, depending upon whether the apparatus is used for loadilig or unloading operations. Since: the otiter conduit section C is pivotally connected to the outer end of the inner section B for movement about a horizontal axis, and since means are provided on the dock, not only for moving the inboard conduit section B @about the mutually perpendicular axes of its universal mounting, but also for pivoting the outboard section C relatively to the inner section B, a lone operator on the dock can maneuver the conduit into a position wherein it is an easy matter for one person to couple the distal end of the conduit A to a selected conduit F (FIGS. 1, 3 and 5) on a barge G or other vessel moored to the dock. In all of the illustrated embodiments of the invention, the conduit E terminate@, in a vertically disposed riser pipe 20 which is supported on the dock D by a frame 22. A 90' elbow 24 is connected to the upper end of the ris-.r pipe 20 by a vertical swivel pipe joint 26. (Throughout this description of the invention, the designation of a swivel pipe joint as being horizontal or vertical refers to the direction of its axis about which one of its relatively movable parts can rotate with respect to the other.) A second 90' elbow 28 is connected at one of -its ends to the elbow 24 by a horizontal swivel pipe joint 30, and the other end of the elbow 28 is connected to the inboard section B of the conduit A. Thus the conduit section B is mounted for universal pivotal movement, i.e., freedom of movement about vertically per@pendicular axes adjacent the inner end of the section B. A 90' elbow (not sbown) is connected to the @outer end of the conduit section B, and is connected by a horizontal swivel pipe joint (not shown) to an elbow 32 which is connected-to the inner end of the outer conduit section C. Thus, the outer conduit section C is peri-nitted pivotal movement within a

3,382,893 3 vertical plane about the borizontal axis of the interconnecting swivel joint. Maneuverin.- of the conduit A so that its distal end ispositioned adjacent the conduit F on the barge, as well as maneuverin.- the conduit to its retracted position, is facilitated by a mechanism H-1, H-3 or H-5 (FIGS. 1, 3 and 5, respectively) that holds the apparatus in any position to which it may be adjusted. - Nevertheless, in each iiistance the holdin.- mechanism is yieldable and the swivel joints that interconnect the two conduit sections as well as those that pivotally support the inner section and connect the same to the stationary conduit E on the dock D, are freely movable. Therefore, the apparatus is enabled to accommodate itself to any normal movements of the bar.-e relative to the dock while a loading or unloadiii.a opel-ation is in pro.-ress, so that ris'@ng or fallin.- tide, movem-,nt of the ship alon.a or toward or away from the dock, and chanes in the vessel's freeboard due to increased or decreased extent of loadin.- will have no harmfiil effect upon the apparatus or upon its efficiency in conductin,@ Piuid between the dock and the vessel. The outer end of the outer conduit section C is connected to a 90' elbow 34, which is in turn connected by a horizontil swivel pipe joint 36 to a second elbow, not shown. Said second elbow is connected by a swivel joint 38 to a third elbow 40 wbich is connected by another pipe swivel joint 42 to a fl,inge connector 44. Thus it can be seen that the open end of the flan-e connector 44 is universally connected to the outer end of the conduit section C by means of the swivel joints 36 and 38 so that the open end of the flange coupling 44 can be presented in any desired orientation. The swivel joint 42 permits rotation of the flan.ae couplin.- 44 to match up the bolt holes with a companion flan.-e 45 on the conduit F fixed to the ship or bargc G. Part of the weight of the articulated conduit A and of mechanism yet to be described mounted thereon, is supported directly upon the riser pipe 20 through the horizontal swivel joint 30. In the embodiment of the invention illustrated in FIGS. I and 2, the part of that weight which tends to rotate the conduit A is supported by the hereinbefore mentioned maneuvering means H-1, which includes a mast 50 fixed to the frame 22 and a wincb assembly 52 mounted on the mast having a cable 54 which extends upward over a sheave 56 rotatably mounted at the upper end of the mast 50 and connected to a fitting 58 fixed to the inner section B of the articulated conduit A. A cable lock assembly 60 is fixed to the mast 50 adjacent the sheave 56 and is actuated by means of cables 62 connected to a hand levdr 64 adjacent the winch 52. With the lever 64 in one position, the cable 54 can run freely throtigh the lock assembly 60; whereas when the lever 64 is sbifted to another position, the assembly 60 grips the cable 54 and thereby becomes effective to support the inboard conduit section B. When the handle 66 of the winch is rotated to wind the cable 54, the articulated coiiduit A is swun@ upward and inward toward the mast 50. Conversely, when the handle 66 is rotated in the opposite direction to unwind the cable 54, the articulated conduit assembly A is permitted to move downward and outward from the mast 50 under the influence of gravity. The outer hose section C is moved relatively to the inner section B by means of a sheave 70 fixed to the elbow 32 which interconnects the two conduit sections B and C. Two cables 72 and 74 are dead-ended on the sheave 70 and extend inward over a freely rotatable sheave 76, which sheave is mounted on the horizontal portion of the elbow 24 which mounts the inboard swivel joint 30 on the riser pipe 20. The inner ends of the cables 72 and 7,',t are wound in opposite directions on the drum 78 of a second winch 80 mounted on the mast 50. When the handle 82 of the winch 80 is turned ' one of the cables 72 will be wound onto the drum 7 8 at the same time as the other cable 74 is unwotind from said drum, thus rotating the sheave 70 in one direction or the other, dependin@ upon the direction in wbich the handle 82 is turned, 4 thereby pivotin.- the outboard conduit section C relatively to the iniaer section B. From the structure thus described it may be seen that a sin.-le operator on the dock D by the proper manipulation of the two winches 52 and 80, and by swin.-ing the whole ass--mbly abotit the axis of the vertical swivel joint 26, can posiiion the distal end of the outer conduit section C in any desired location within the reach of the apparatus. Then, since the outer coiiduit section C hangs 1( freely from the outer end of the inboard section B, and since the entire assembly supported by the swivel joint 26 is free to turn about the vertical axis thereof, it is an easy matter fc)r a p--rs6n on the barge G to place the flange connector 44 at th,- free end of the outboard conduit sec15 tion C in position for connection to the ccmpanion flan,-e 45 on the conduit F and to couple the two flan@.-cs 44 and 45 to-.ether, thus placin- the apparatus in readiness for loadin.- or unloiding the bar.-e. Frr-,iii t@ie foregoiiig description of the apparatus and 20 i,s mannf-,r o'l oper,,ition, it is clear that since the sheave 70 caii easily be held motiontess while the iiiner conduit men,.ber B is pivoted about the liorizontal axis of tiie iwooard swivel joint 30, the outer coiiduit meniber C can be retairied irl ony selected attitude with respect to the 25 hoizontal wliile tl,.e an.@ularity of the inner conduit member B with respect to the horizoital is altered. Thus the apparatus of the present invention can when occasioti requires, be operated in the same m@nner as t@,e liquid cargo handling apparatus disclosed in the aforesaid @', 0 Patent No. 2,927,607. Ho-wever, the apparatlis of the present invention possesses the additional advantage that the attitude of the outer conduit member is variable independently of movement of the inner condiiit member, with the result tl)at the maneuverability of the apparatus 3 0- of this invention is greatly increa.-ed in respect of both ran,@e, or reach, of the apparatus and convenience in the operation thereof. After the coniiection to the sbip's flan,@e 45 bas beeii made tip, the cable lock 60 sbo,,ild be released, this being 40 accomplislied by appropriate movement of the band ]ever 64 as ibove described. The apparatus is then in a "freewheelin-" condition, i.e., the otiter end of the conduit A is free to follow any movements of the barge which proper nioo@-in.- of the bar.@c to the dock will permit, since 45 no material resistance is preseiited to pivoting action of the vertical swivel joint 26 or of the horizontal swivel joints 30 and 36, as well as the horizontal swivel joint (not shown) wbich interconnects the inboard and outboard conduit sections B and C. 50 Turni,,l.- now to the modification illustrated in FIGS. 3 and 4, most of the e'@ements shown therein are the same as corresponding eleneiits shown in FIGS. 1 and 2 and, bence, are given the same reference numerals. One difference between the first described embodimeiit and that 55 of FIGS. 3 and 4 is that the mast 50, the winch 52, and the cable 54 wl-iic'@i, i-ri the former, hold the articulated conduit A in selected position are replaced in the latter by a couiiterweight 90 mounted on a bepm 92, fixed to the inner condvit section B. The wei@,ht 90 is adjusted 60 alon.- the beam 92 so that it just counterbalances the dead weight of the articulated arm A and tlac parts carried thereby. A further difference in this modification is that the mechanism for maneuverin,@ the outer section C of the 65 articulated conduit A relatively to the inner section B has been changed by makina'the in@-ier sheave 76a a fixe'd sheave, i.e., fixed with res'pect to the elbow 24@ The cables 72a and 74a which correspond to the cables 72 and 74 of the prior modification, ire dead-ended to the sheave 7o 76a as well as to the sheave 70. Two fluid operated pullin,@ engines 94 and 95, each comprisin,@ a ram 96 reciproc'I , ble witl-.in a hydraulic cylincler 97, are interposed one within each of the cables 72ti aiid 74a. By nieans of this ii,ranacniciit, tfle effective lengtli of eit@er cable miiy be 7.5 shortened by actuating the respective ptilling engine

32382)893 5 whil e permitting the otber engine to exhaust as the effective leiigth of its associated cable increases. Thus, power mea ns are provided to effect rotation of the sheave 70 to cha nge the attitude of the outer conduit section C with resp ect to the inner section B. Sinc e the turnin- moment resulting from the attitude 5 of the section C is transmitted by means of the sheave 70 and the cable 72a directly to the stationary sbeave 76a, the attitude of the outer section C of the conduit A with resp ect to the inner section B thereof does not have any effe ct on the counterbalalice H-3. Thiis, the assembly 10 Te mains balanced at all times re.-ardless ol. the attitude of the outer section C of the articulated conduit A with resp ect to the inner section B thereof. A plate 98 is fixed to the beam 92 in such position that 15 whe n the conduit A is in its rest position the plate 98 is bet ween the legs of a U-sbaped bracket 99. A removable clev is p;n (not sbown) fits tbrough aligned holes in the plat e 98 and bracket 99 to lock the cond-ait A in this posi tion. 20 The hydraulic circuit for actuating the pulling engines 94 and 95 to effect changing of the attiti-ide of the outer con duit section C is described in connect@'on with FIG. 7. The hydraulic circuit comprises a reservoir 100 and a pum p 102 driven by an electric motor 104. The pump 102 25 pick s up hydraulic fluid through a strainer 106 and an inta ke pipe 108 and delivers hydraulic fluid under pressure thro u.-h a tube 110 to a control valve 112. A branch tube 114 and a pressure responsive unloader valve 116 con-and 12Z back nect the tube 110 through tubes 118, 120 30 to the reservoir 100. A second branch tube 124, connects the tube 110 throu.-h a manually operated valve 126 to a pressure gauge 128 to provide visual indication of the pres sure being applied to the control valve 112. Tubes 130 and 132 connect two delivery ports of the control 112 35 with t]-ic pulling engines 94 and 95, respectively. When the core 133 of the control valve 112 is moved upward as viewed in FIG. 7, fluid pressure from the live 110 is appl ied through the line 132 to the pulling engine 95. At the same time, the fluid discbarged from the engine 94 40 thro ugh the line 130 is conveyed to a discharge tube 134 and tbrough a restricted orifice 136 and the return tubes 120 and 122 back to the reservoir 100. Similarly, when the core 133 of the coiitrol valve 112 is moved - downward as viewed in FIG. 7, hydraulic pressure from the supply 45 line 110 is applied through the line 130 to the pulling engi ne 94 while the fluid discharged fron-1 the engine 95 is connected to the discharge line 134 back to the reservoir 100 through the restricted orifice 136. In order to provide a "freewheeling" connection for 50 the apparatus when the conduit A is connected to a sbip or barge adjacent the dock, a by-pass line 138 is connect ed between the lines 130 and 132. A solenoid actuated valve 140 is inserted in the by-pass line 138. Wheii the valve 140 is open, as shown in FIG. 7, fluid can flow -5,5 freely between the cylinders 97 of the two en-ines 94 and 95, with the result that the outboard section C of the conduit A can @move about the horizontal axis of its pivotal connection to the inboard section B without any material resistance. The valve 140 must be closed in 60 order to alter the attitude of the section C by means of the hydraulic circuit. If for any reason movement of the ship relative to the dock should occur while the conduit A is connected to the ship and the valve 140 is closed, any excess pressure 65 btiilt up in the pullin- engines 94 and 95 as a consequence of movement of the outboard conduit section C relative to the inboard section B, is vented from the conduit 130 elief or 132, as the case might be, through a respective r 70 conduit 142 or 144, to a return coiiduit 146 and back to the reservoir 100 through an unloader valve 148. It will be noted that the conduits 142 and 144 are provided with check valves 150 and 152, respectively, whi-,h prevent communication between the two conduits 130 and 75 6 132 during application of pressure therein to manipulate the conduit section C. Returning now to FIG. 3, the broken center line A, thereon indicates the rest position into which the conduit A is placed when not in use. The broken line Ah shows how the conduit may be placed to make connection with a ship or barge having a high freeboard adjacent the dock D as indicated by the broken line GhIn the use of this modification, one operator on the dock may place the articulated @conduit B into the desired vertical orientation by manually rotating the same abotit the horizontal axis on the swivel joint 30 and he may adjust the conduit A horizontally by manually turning the assembly about the vertical axis of the swivel joint 26. Because of the coudterbalancing action of the counterweight 90 on the beam 92, the apparatus will stay in any set position in which it is placed. The operator on the dock may vary the attitude of the outer conduit section C by means of the hydraulic circuit described above, to place the flanae coupling 44 at the distal end of the conduit section C adjacent the companion Ran,-e 45 on the conduit F of the barge or ship G. Although the modification illustrated in FIGS. 5 and 6 is similar to that of FIGS. 3 and 4, it differs therefrom in the means for manipulating the outer conduit section C. In the modification of FIGS. 5 and 6, the cables 72b and 74b which a@ain are dead-ended on the outer sheave 70 are dead-ended at their inner ends on a rotatabl-- sheave 76b. A sprocket 200 is fixed to the sheave 76b and a chain 202, which is trained around the sprocket 200, is attiched to the pistoiis of two hydraulic pullinengines 94b and 95b which correspond to the pulling engines 94 and 95 of the previous modification. However, instead of being interposed witbin the cables 72b and 74b, the engines 94b and 95b are pivotally mounted on a plate 204 wbich is connected by brackets 206 to the elbow 24 above the vertical swivel joint 26. Actuation of the hydraulic en,@ines 94b and 95b effects rotation of the sheave 76b, and through the cables 72b and 74b rotates the sbeave 70 to chan,e the attitude of the outer section C of the articulated conduit A. The hydraulic eireiiit for operating the engines 94b and 95b is the same as that explained above for operating the engines 94 and 95 of the modification illustrated in FIGS. 3 and 4. It will be understood, therefore, that the operation of the embodiment of the invention illustrated in FIGS. 5 and 6 is the same as that described above in connection with the embodiment illustrated in FIGS. 3 and 4. While certain embodiments of the inve-@ition have been shown and described herein, it should be noted that further changes may be made therein without departing from th.- s irit of the invention as defined in the appended claims. p The invention having thus been described what is believed to be new and desired to be protected by
