shapin-, the glass and finally the movement of the radius arm and outer arm are re@umed by the cam run 13 d and th4 chiiek is positioned with respect to the blowing apparatus, the run 28d being so shaped that at this instant the blow e is vertical and .is stationary at this ti@pei@ The motion of the radius arm and outer arm i also arrested by the fact that the actuating slide io of the former is engagin,g the machine run 13e of the peripheral cylinder. During the time that the I)low-pipe chuck is in the blowing position, the blo ' machine, by wing mechanism , not necessary to be described i5 here, removes the blowpipe from the presented arm by pressing back the bevelled gear . 19 on the chuck and the latter remains in this position while the chuck is being rotated towards the furnace, which is ef20 fected by the return run 131, of the peripheral cam, the chuck being rotated by the run 281, ol the end cam. In swinging back towards the furnace the chu6k from mthich. the blow-pipe has been removed passes the 25 blow-pipe carried by the other arm which is goiiag toward the blowing machine, but as there is no blow-pipe at this time upon the arm travelling from the blowing machine they clear each other. After pass.age 30 of the empty chuck past the loaded one I aiil attendant inserts a blow-pipe into such empty chuck in the manner before described and by a continued movement of the radius arm and outer. arm the blow-pipe 35 is presented horizontally into the mouth of the furnace and then dropped by tho inclined run 281 of the end cam therein to assu[me the position shown in the left of 'Fig. 1. It will be noted that this return 40 movement of the arms from the blowiiag to the gathering position it. uninterrupted and that when the L)low-pipe has I)een pr6perly presented iiato the furnace its translatin-a movement is arrested by the actuating sli(fe' 45 engaging the gathering run 131, of the p@ripheral egm track, while after the blowpipe has been dropped into the glass such movement is a-rrested by its actuatiiig stud engaging the concentric run 289 of, the end r@o cam. As it is desiiable at cortain- times, particularly in the gathering and marvering, that the blow-pipe have a rotation around its longitudinal axis,. this motion i is im55 parted to it by the geariiag before d6scribed and for convenience of construction this rotatioii is uninterrupted.

The swilaging @mechanism for the blow-pipe as'well as the traversing mechanism for the blow-pipe chuck are intermittent in their action in tliat they liave p@sitions of rest correspondiiig to the gatli@4 ering and blowing positions and to a position (marvering) intermediate tliereof. It further embodies suitable marverino, me@hanism and means whereby the seier@'I mechanisms above referred to i),re brotight into and .2.-) maintained in synchronism witli eacl-i other aiid are i@aused io properly and successively perform the op@erations for whicli they are designed. The base of the machine comprises a suitable wheeled frai@le 1 adapted to be secured in a fixed position in respect to a blowing @ mechanism A of the general charactor described in niy other application S. N. 589,786 hereinbefore ief6rred to and to be maintained in a fixed position in respect thereto. The wheeled frtme has on that end tliereof opposite to the end to wliieh the blowing mechanism is secured and on each side of its longitudinal axis, an -up-standing skeleton 4U frame 2 having a circular bearing 3 projecting from the top center't,liereof inwardly. On each of the bearings 3 is motinted a hub 4a of radius arm 4. As the several parts which are mounted on or coactino, with the 45 radius arms are in duplicate, one for each side of the frame and are similar, I will for convenience confine the following description to one set of them. The outer end of the radius arm has a hub 50 4bin -%vhich is inounted a sleeve 51, on the proj , ectiiig innei end of which is keyed the hub 5b on one end of an otiter arm 5, the opposite end of which ar,m is formed into a hul@ 5e to support the blowpipe receivin,g mechanism .55 or chuck. The lower. end 4" of the radius arm is continued- downwardly and bent inwardly Where it is formed into a seginental rack 8 located above a corresponding segmental rack.7 of greater radius carried by 60 the skeleton frame, a pinion 8 being interosed between the two segmental racics and Eaving a motion longitudinally of the machine imparted thereto by means of mechailism which will be hereinafter described, 65 whereby the radius' arm will be caused, to swing.in an arc of a circle aroilnd the radius arm bearing 3. As before stated the outer arm @5 is keyed to one end of the sleeve 51, mounted in the upper end of the radius arm 4 and flie oppo- TO site end of the said slee-%,e projects to the fi-oint of the radius arm and has keyed thereon.a pinion: 9 which meshes wit-h a segmental r'ackga tlie, ends gb of which extend longitudinaby of the macliine and are carried by 75 parallel links 10 pivoted to th@ skeleton frame symm@t ically in respect to the axis of movement of the -radius arm, a suitable curved guide 9c being carried by the outer face of the radius arm to maintain the rack 80 in en-agement with the said pinion. Owing to tliivs construction the swina of the radius arm about its sleeve will be accompanied by a chanoe in the meshing position of the actuating i@inion 9 for the outer@ arm and its seg- 83 mental rack, wliereby as tlio radius arm is swung to. either sid@ of'a,vertical line, the outer arm will be given a further movement around its sleeve and swung in respect to the said radiu's arm, the relation between the 90 radius- arm and the outer arm in the extreme positio'ns of the former being such that the latter is projected towards-the furnace or towards the blowing machine according tb whethei- the radius arin is to one or the otlier side of its -vertical position. The pinion 8 interposed between the two se,-mental raclcs 6 anct 7 is mounted on the link 11 from a Idn-gitudinally movable slide 12 guided iii bra7ekets 121, from the inside 3'0 of the skeleton frame and having inotion inip@rted thereto, by a stud 12 b thereon engaging a cam track 13 in the periphery of the druni 14 constantly d@iven by mechanism to be hereinafter described and carried in 1(5 beai-ings 14& in the skeleton frame. The track is so shaped that while parts of it 13b@ 13 d and 131 extend spirary of the periphery of the drum, thereby imdarting motion to the slide-longitudinally of the base through 110 the intervention. of the p.inion and se,-ment,,Il racks and a swinlring motion to the radius arm 4 about its sleeve hub 3,.portions 1311, 13", and 131, of, said traclc a-re located in planes at iiglit angles to the axis of rotation 115 of the- -@ilincLer, whereby periods of rest ar,3 obtained in the swinging motion of the radiiis arm,, such positions of rest corresponding and being of proper extent to permit the actions and tlo 120 ip@ in respect to nging motions fore described effect the swinging motion of the outer arm 125 5 around the uppe'r ends of the radius arms and hence the instrumentalities before described e:ffect a traversing motion of the blow-pi@e chiiek. between the furnace and the blowing devices, such motion being ae130 companied by prope.r periods'of rest.

propriate mechanism 30a whereby th@ marvermg rohers carried thereon may be caused to approach and recede from each other. The marveri-n(r rollers are driven by gears 29b on the shaft tliereof meshing with idlers 290 mounted in the links which in turn mesh, with the pinion 29d mounted on the shaft 291, on which the links themselves are pivoted. This shaft is driven'. by an ap,pro10 priate meelianism to be herein,,tfter referred to. Mounted in the base frame of the fnach' to one sicte thereof is a suitable main me dri ive.31 (shown in dotted lines in Fig. 1), 15 such as an electric motor, the shaft 311, of which carries a worm'31b mesliing with a worm 311, on the vertical driving shaft 29of the marverer. The main shaft 311, of the ld motor furtber carries pinio-n 3 driven 20 through an idler 3111, a pinion mounted on the lower transverse shaft 311 of the machine which latter shaft carries on each end a worm 319, each of wliich engages a worm wheel 31h f ast upon the end of the 25 actuating drum 14 of the correspondin(y arm whereby translating motion of the ch@,ck is eitected. Such transverse shaft moreover carries thereon on each side of its center a sprocket 'wheel 311 from each of wbich 30 throtigh the intervention of sprocket chains 3le motion is transmitterl to the sprocket wheel 20- carried on the inner ends of the shaft 20k from 'which the blow-pipes are rotated. 35 1 bave hereinbefore stated the moldino, and blowing mechanism which is shown diagrammatically in Fi,-ure 1 is of the character shown in my other application, Serial Number 445,252, filed July 24, 1908, re40 newed on October 29, 1910, as Serial Number 589,786. As shown in Figure 15 of the present drawings (which figure is a cop:y of Figure 3. of the drawings in the last -named case) such mechitnism comprises a base D' 45 @upporting a vertical tubular standard D, in which is contained the vertical drivi-ng shaft F,, driven through bevel gears F and F' and a clutch G by a motor H. The clutch G is of such a character that it releases itself r)O after driving the shaft E through a complete revolution, and is adapted to be thrown into engagement to start the rotation of the shaft by means of a yoke 9. formed upon the rearwardly extendino, end 55 of a lever g' whidh is pivoted near its upper end on the sta]adard, and whose upper end is bifurcated to receive the blow-pipe C, the weight of the blo-w-pipe wben inserted therein a@ctuating the @lu-tch. A -cam track H' is 00 formed on the lower end of. the vertical shaft, and in it a stud A, connected by links hF to the pivoted mold halves I, runs, the @rrangement bei-ng sudh that with the shaft m its normal position the mol4 halves are -05' open, and that.during the rotation of the shaft they are, closi3d and so held for a proper period before being opened. On the upper end of the standard is the air head la, the air valve lb of whicli is aetuated- at ab6ut the time the mold is -closed, 70 througli t6@ rotation of the sllaft, to admit blow'mg air. - In the operation of the device an arm 5 being in the position sh . own in the left of Fig. 1, the radius arm 4 will by the rota- 75 tion of the cam cylinder 14 be swung to the right about its sleeve 3 and in this mov6ment the outer arm 5 will swing about its pivot on the buter end of the radius arm downwardly and toward the 'right, 50, decreasino, the angle between it and the radius arm. Durin- this movement in order to clear the mouth of the furnace ot the pot it is necessary in the construction shown that the gathering end of the blow- 85 pipe be lifted by s g the bl wi'lgin ow-P iipon the axis of its chuck. This is effeeLP(d' by the stud on the vertical slide 27 at this time being lifted bv the i-nelined portion 281, of the cam track 28 on the end of the cam 00 cylinder 14. The continued rotation of the drtim s-wi-.ngs the radiiis arm and ihe outer arm from the position in which the blowpipe will cle.ar the pot or furnace to a position in which the blow-pipe chuck will be 95 over the marverer, this being effected by the swinging of the radius arm around its sleeve and the swinging of the outer arm upon the. radius arm. This -will also be accompanied by a swinging of the blow@. 100 pipe in a v-ertical plane around the axis of the chiick so that at the time the chuck is above the marverer the gathering end of the blow-pipe will be hanging vertically from the chuck, which may De effected with 105 a con@entric ruiri 28 b of the track 28 by 'a proper proportioning of the gearings 24, 22", 22", 23, 21c, .21",'and 21. I-laving reached the marvering posit ' ion referred to, the motion of the radius arm and the outer 110 arin is arrested by reason of the fact that t-lie stud 12 b at this time is engaging the marverin 13c of the peripheral groove of the fiiarduenr, the marvering rollers being so timed in respect to the ariii that at the 115 time the glass -upon the blow-pipe, is presonted between them, their surfaces are separated to their raaximum extent. During this time that the blow-iron is held stationary between thi3 marvering rollers, 120 the latter ma'ke one or more complete rotations, thus ma7ering the glass upon the end of the blow-iron. When the marverers ha-ve -completed their full rotation and have released the glass (the radius arm and - the 125 outer arm, being still stationary), the stud 27& works in the wave r cam track 28 upon the oscillate or swin@-the. cal plane around ihe ax 281, o the on to rapidly in a vertichuck, thus 130
