Unite Ststes Patent'Office 2@8279663 2,827,663 CANDLE MAKING MACHINE George Spiros Flomp, San Jose, C-2n-. Application May 24, 1954, Serial No. 431,837 5 Claims. (Cl. 18-24) This invention relates to the art of making candles and more particularly to certain novel improvements in candle making machines. In the art of making candles it has been the practice to mechanize the process of dipping with the purpose of simulating the steps in the hand dippin.- of candles. As of old, a wick is periodicahy dipped into molten wax and withdrawn therefrom with a layer of wax deposited thereon for cooling to a predetermined temperature. This dipping process is continued so as to collect coat upon coat of wax until the candle has developed into a taper or candle of the diameter desired. In this process it is very important that each coat of wax deposited upon a prior one be welded and merged into one homogeneous body of wax. Otherwise each coating of wax would become stratified and be likely to break away from the preceding coats of wax. It will therefore be understood that in the art of candle making the timing between each immersion as well as atmospheric and temperature conditions between immersions are critically important to the production of a sound, uniform and well constructed candle. These facts are fundamental whether the candles are hand made or machine dipped, but must be reconciled with in the manufacture of candles in machines. More particularly, in the making of candles in a machine it is usually the purpose to mass produce, i. e., to make great quantities of candles simultaneously. This necessitates the suspension or stringing of the wicks in groups that will fit into the vat containing the molten wax which of course requires that the wicks in each group thereof be in close proximity to each other leaving enough space between them to accommodate the girth of the indvidual candles and yet leave sufficient clearance between them to facilitate the cooling of the wax between each dipping operation. In addition to the foregoing, it is equally important to allow sufficient cooling time between each dipping operation so that the last applied coat of wax will not melt away during the next or successive dipping operations. With these fundamental requirements in mind, it is an object of this invention to provide a candle making machine in which candles siinulating hand made candles can be mass produced. Another object of this invention is to provide a machine in which groups of candle wicks strung on a frame can be placed on a conveyor for periodic dipping and intermittent cooling in timed relation. In this connection it is a further object to provide wick holding frames readily attachable to an automatic conveyordipper so that new groups of wick holding frames can replace those on which candles are already formed without stopping the intermittently operated conveyor-dipper. Yet another object of this invention is to provide a conveyor for supporting a plurality of groups of candle wicks strung on frames for intermittent movement toward a dipping station. In this connection, it is an object to ate,-ited Mar. 25, 1953 provide a dipping station in which each group of candle wicks on a frame upon arrival at such station automatically sets the latter in motion for dipping the frame into molten wax for a predetermined time after which such ti frame is automatically raised and again assumes its position in the conveyor for intermittent movement thereby. Another object is to provide a candle making machine for conveying independent groups or racks of candle wicks intermittently to a dipping station, dipping each such group iti while other groups are maintained in line for successive positioning at such dipping station and subject to removal from such line and replaceable by a new group or rack without interfering with the intermittent operation of the machine. 1.5 These and other objects and advantages of the present invention will become apparent from a reading of the following description in the light of the drawings in Nvhich: Fig. I is a side elevation partly in section and broken 2t) away to illustrate the general assembly of a candle making machine embodying the present invention. Fig. 2 is a fragmentary horizontal section taken along line 2-2 in Fig. 1. Fig. 3 is a horizontal plan view taken from above in Fig. 1 and substantially along line 3-3 thereof. Fig. 4 is a fragmentary horizontal section through the machine s'-- iown in Fig. 1 and taken substantiafly along line 4-4 thereon. @ Fig. 5 is a plan view of the drive mechanism of Fig. 1. 3t) Fig. 6 is a schematic diagram of the control system and mechanisms associated with the dipping station shown at the ri.-ht in Fig. 1. Fig. 7 is a perspective view of one of the frames on which x,,,icks are strlng and constituting one group thereof. 3.-) Ref@-rri-@ig to Fig. 1, the candle making machine of the present invention, designated 10, generauy comprises a conveyor 11 connected to a drive 12 for moving a plurality of grotips of candle wicks 13 through a circuitous path to and from a dippin.- station 14 for periodic dippin.- 40 into a vat of molten wax 15 under the control of an automatically operated control 16. The conveyor 11, for the purposes of the present invention, is mounted for rotation about a fixed shaft or mast M. The conveyor preferably includes a tubular 45 shaft 20 mounted for rotation on the fixed mast and coupled to the drive 12. The conveyor has a plurality of el@evator guide shafts 21 supported for tip and down movement relative to an annular frame 22 carried by the tubular shaft 20. r'O The j'rame 22 consists of a plurality of arms 23 extending radially from a hub 24 secured to the shaft 20 at the desired elevation. These radially extending arn-is 23 are further supported by straps 25 each of which has one of iLs ends secured to a flange 26 mounted on top of the 55 ttibular shaft 20 and its opposite end secured as at 27 to a respective one of the radial arms 23 for stipporting the latter at right angles to the mast. Each of the radial arins 23 are further supported in equally spaced relation by an annular band 28 connected to each of these arms 60 23 adjacent their outer extremity, i. e., between the latter and the point of connection 27 between each arm and the diagonal strap 25. The extremity of each arm 23 is prov.,ded with a guide sl.,.- ve 29 having its guide passage 30 disposed vertic-al 6-5 to receive one of the elevator guide shafts 21 hereinbefore mentioned. Each of the guide shafts 21 is ident:cal and therefore like reference numerals will identif@, like parts thereof. Each guide shaft 21 has a tapered lower end 31 (Fig. 7) with a diametrical bore 32 for re70 ceiving a pin or bolt 33. Just above the tapered lower end 31 is a cone like collar 34 (Figs. I and 6) having its

upper and lower limits of movement of the elevator guide shaft 21. These switches 87 and 88 are fixedly mounted on the stationary control panel 60 and have their actuating levers in the path of movement of the lateral arm 92 for the purpose explained. However, it should be noted that the upper switch 87 is normally closed and the lower switch 88 is normally open. Consequently, when the ami 92 drops with the released elevator guide shaft the upper switch 87 assumes circuit making condition for reasons later to become apparent. Now, when the particular elevator guide shaft 21 of which is at the dipping station reaches its lowermost extremity of movement, i. e., when the candle wick frame 81 associated therewith is immersed in the molten wax, the lateral arm 92 strikes the actuating lever on the lowermost switch 88 Nvbich completes the electrical circuit 69 to a timer relay 94 for establishing a circuit to the coil of the three-way valve solenoid 63 via the normally closed i.ipper switch 87. Thereupon the three-way valve 63 is changed in position to admit compressed air from supply pipe 62 into the lower region of the cylinder 57 via the pipe line 61. Thus the compressed air lifts the piston 56 and with it the guide shaft 21 connected thereto. As the elevator guide shaft 21 rises the lateral arm 92 thereon strikes the actuating lever on the normally closed upper switch 87 whereupon the circuit to the coil of the threeway valve solenoid 63 is broken to allow the three-way valve to return to normally closed condition. In this manner the relief port 65 again becomes communicated with the lower portion of the cylinder 57 to relieve the latter of air pressure. Simultaneous with the foregoing the roller 91 on the lateral arm 92 passes the end of the latch lever 90 which thereupon prevents the lowering of the elevator guide shaft 21 upon relief of compressed air from the cylinder when the three-way valve returns to normal position as just stated above. The cycle of operation at the control 16 thus being completed the motor 75 having continued to drive the rnain 76 and with it the Geneva drive 77 so that the latter now makes a quarter tum. This action of the Geneva drive is again transmitted to the small gears 78-79 to inove the gear 73 on the tubular shaft 20 another step (i. c., the circumferential distance between the elevator guide shafts 21). Thus the elevator shaft 21 which was previously lowered will again have its disc head 41 suppo.-ted on the fixed track 43 and the disc head 41 of th,next successive elevator -Uide shaft will now be disposed in the channel track 53 'or support thereby. The foregoin.- intermittent operation of the conveyor 11 and each elevator guid.- shaft 21 continues under the automatic control 16 so as to dip each group or rack of candle wicks W into the vat 15 of molten wax. In this rnanner after each dipping operation each rack or group of wicks is carried around the circuitous path by the conveyor 11 giving the wax coating applied to the wicks a chance to cool and harden sufficiently bej'ore again b@,ing didped into the vat of molten wax. With each immerSion of the wicks W of each group thereof the additional coats of wax build up upon the previously applied coats thereof in the same manner as heretofore practiced in hand dippin.- of candles. After the proper number of dippings of the several racks or grouns of wicks each such rack can be removed from the machine by withdrawal of the pin 33 from the boss 80 and tapered lower end 31 of the elevator guide shaft 21. A newly strung rack of wicks W is then attached to the elevator guide shaft while other racks are being dipped and the machine 10 thus continues to operate without stopping. Vy'hile I have described my improved candle making machine in specific detail it will be understood that the same is susceptible to alterations,- variations and/or modifications witnout departing from the spirit of my invention. I therefore desire to avail myself of all alterations, variations and/or modifications as fairly come within the purview of the appended claims. 6 What I cla'un as new and desired to protect by
