'The rear end of the rod 63 has a roller 66 journaledthereon; 'whichroller engages a cam track 61 extending about an arciiate plate fixed to the framework of';the* apparatus-* :and during movement of a rod"53 along thjlower run of the path of travel of the chains 6 I; each,

I

As indicated in Figure 6, thema ic conveyor 22 moves out or contact with the endless chain 21 shortly after a can has passedbeneath the spray guns, and the rotation of the cans will cease at the latter point. At the same time, as indi- .cated in Figure .1, thexpresser rod 63 which has heretofore been in contact with the bottom of the can, will be retracted from the can by reason of the fact that the roller 66 on the presscr and will come into contact with a fixed cam shoulder 95 arranged concentric with the axis or the sprocket wheels 62, cam shoulder 95 being. ofsuch conformation that it will retract each presserrod 63"from;a' can bottom" as the presser rod moves downwardly and about the sprocket Wheels 62 larly' moving supporting chains i filc awayqfrom the stationary cam 61: so that the roller 66' of that rod will be entirely disengaged from the cam 61 and the rod will be held in contact withth'bcttom Oi. the can by-lts: spring 64, as indicated in Figure ll Almostimmediately thereafter; as shown in Figures 6 and '7; the sprocket wheel 28 fixed intermediate the length of the can Supporting spindle 25 will contact with the sprocket chain 21', which moves about sprocket wheels 8| and .82 (Figure Gland in the opposite direction to the direction of travel of main conveyor 22,Ias shown by thearrows in Figure 'l.

The spray gun 28a is supported at such an angle by the framerflfl that a'wm direct lacquer against the conical top portion" of; the can and somewhat about the exterior of the can during the spraying, lacquer will be deposited over all of the above described exterior surfaces of the can. Also, by reasonof the fact thatfthe rotation of the cans continues for a brief time after each can has passed outof therange of the spray guns, the lacquer will be freely flowed over such exterior portionoi the canstdbe evenly distributed thereonz Due to the 'f act that the can is supported byvits mouth, as indicated in Figure 9, the s ray gun 28c may not projcctiacquer over the entire lip-surface ofthe can. l 1

As shown in Figures 8and= 9, thelupper runrof can rotating chain z'l mcvcsalonga "fixed guide v mouth. Due to the rapid'rotation of the can a movement of the can through the drier.

. The mechanism for transferring cans from the studs 24 to the carriers35 is described in detail in said: divisional application. However, the opfrom the following description thereof.

After leaving the drier IS, a can mountedvon a'can sup orting head M and moving with the eratlori of this mechanism will be entirely clear "lowerrun of the conveyor 22 will move to the left as viewedin Figures -1 and 3 so that the can will be carried beneath (and entirely clear of) the @infeed spider 2| to the extreme end portion of v the run oi: the c0nveyor 22, which encircles a large double sprocket wheel 126 bestshown in "Figure lph sprocket wheel I26 is fixedto a shaft I21 (Figure 3) suitably journalled'in the side frames of the apparatus and, as shown in Figural, is

V geared asat I28 to ashaft I29 at the extreme and of the apparatus which is driven through a series of sprocket chains I 290, from: the motor The-two sprocket chains of which the main conveyor, 22, is formed will be engaged by the two sprocket wheels of double sprocket I26 so that therspi ndles 25 will be maintained horizontal.

Shaft I21 has the spider 3| fixed thereto alongsidethe sprocket wheel I26\and thespider 34 is fixed to shaft I21 at the opposite 'side of sprocket 1 I251 As shownin Figure 1, as a spindle 25 moves adjacent double sprocket I26, the can C carried by the supporting head 24 of thatspindle will move into a pocket/of spider 3i and rotation of the s pider" with shaft IZlwill move the can upwardly as shown in Figure 3. Just before: moving upwardly about the spider 3|; the side wall of veach can willi contact with'a. pair of guide strips 530 (FigsfZ and 3) which will forcethe can lie in a horizontal plane.v r I A lateral guide bar I35 is positioned adjacent the guide bars [36, guide bar I 35 being inclined outwardlytoward the planer-0t the spiderilc so ported in the pockets of spider 3| spider-3L with the side walls of the cans.

helical guide bars I32 (Figure 1); surround the periphery of transfer drum 32, the infeed ends I33 of the bars I32 projecting between the discs I34 of which the sprocket 3| is formed, with the extreme lower'ends of the infeed portion I33 f the guide bars positioned substantially directly between the axes ofthe spider 3| and transfer drum 32 and betweenthe two. discs of which spider'3l is formed.

By theabove arrangement, each can will be freed from its supporting head 24 immediately after it comes in contact with the lower guide I30 and lateral guide I35 and the cans will then be moved'up the lower guide I30, free of the conveyor 22, by engagement of the pockets of th Just after the can thus carried by the spider 3| comes into engagement with one of the pockets or grooves I3! of transfer drum 32 fixed to shaft I29, the opposite portion of the can will also come into contact with the infeed'end I33 of the helical guide bars I32, so that the can will 'now be completelystripped from'the spider 3I'and will move upwardly'with the transfer drum 32.

' A'pipe I40 of helical form (Figure 1) also encircles the periphery of transfer drum 32, this pipe being positioned somewhat to the side of the'helical guide bars I32 nearest the plane of spider 32, and between these guide bars andthe periphery of the transfer drum (Figure 5) Pipe I40 has apertures therein'on" its surface facing along the grooves I 3| and the pipe is supplied with compressed air from a suitable source through a line MI. The guidebar 35a, also of generally helical form, is positioned onthe side of the guide bars I32 opposite pipe l lfl' and bejtween'guide bar I 32 and the periphery of the transfer drum. The guide bars I32 and 35a and.

the pipe I40 are suitably supported by brackets 7 adjacent the drum 32' as illustrated in Figure 5.

By the above construction of guide elements about the transfer drum 32, as soon as a can is completely freed from the spider 3|,it will be forced upwardly as viewed in Figure 1 by the jets of compressed air issuing from the pipe I50. Such movement of the can along the grooves ISI will cause the'can tobe moved out of the vertical plane of the spider 3| and into the plane of spider 34. It will be observed that the provision of the helical guide bar 35a opposite the compressed airpipeidfl will cause cans to. be

moved along the grooves I3| of the transfer drum bya continuous and gradual movement. That is to'say, there can be no sudden movement of the cans along the grooves such as might cause the mouths of the cans to be dented.

Each can will remain upon the transfer drum 32 during one full revolution of the same, and, as best indicated in Figure 1, at the time that this one revolution is completed, the mouth" of the can will project from the far edge of the drum and will partly lie in the spider or disc 33. In other words, as indicated in Figure 1, each can enters the drum 32 directly in the plane of the spider'3l but,"-beca.use it moves in a helical path, leaves the drum in the plane of spider 34,

somewhatasindicated at A inFigure l, iAt this moment, also,-the can will ride, beneath an arcuate guide bar I45 (Figure3) whichbverlies the can receiving spider. 34 r and the-can will be stripped from drum32. and-placed in an alignedpocket of spider 34. As shown in Figures 1 and 2, the substantially helical guide bar 35a which surrounds transfer drum 32 has itsbutfeed end |43a extending away from: the transfer drum 32 withlthe extreme end;portion thereoflretum bent toward thevspider 34Lwithethe result that as upwardly moving. cans are removed. from-' the' transfer spider by fixed, arcuate. guide ,|45,;the

cans will simultaneously be moved axiallyof the spider 34 and into cup-shaped holdersprovided on the main conveyor; 22 andqofsufllcient diameter to receive the body portion of'the can,

but of such length that, at least the conical-top wall ofthe can will projectitherefrom.

After a can has been positioned in the cup-,

shaped carrier or'supportingme'ans 3.5 as illustrated in Figure 1, the movement ofithe-main 1 conveyor 22ltoward the drier will bring the'pro- Y l jecting cone-shaped portion'of the. canbeneath the spray. gun 36, as shown'in Figure 1; :Gun 36 is supported at such an angle that it will direct lacquer upon the mouth of the can, including the inner wall of such mouth.- Duringumovement beneath the spray-gun 36; the spindle 25 to which the carrier 35 ;is secured will be rotated by movement of the endless chain 21 beneath the same and'in'engagement with-the sprocket. 28

which is secured to the spindle.

After the spindle has moved out of engagement with the endless chain ZIandfrom" beneath I spray gun 3B, the can C'will be carried intdthe' v drier I9, following the samecourseof travel that it followed when supported upon'the' supporting head 24. f However; as describedin :saidoivisional application, during the: present" fmov'ement through the drier,the can will move-onlythrou'gh the heated portion of the drier; that is, when the carrier 35 leaves the rear end of the'oven; the can will be removed by a suitable clan-reinow ing apparatus such as disclosed in saiddivisional application. 7

The operation of the entire apparatushas'b'een I set forth in the general description'and operation of the apparatus at the 'openingportionof this specification. Figure l illustrates how two apparatus of the present'inventon maybe positioned side by side. in such a way as to conserve floor space, namely by' having the drier blower and motor of one drier I9 onset with respect to the blower and motor of the other drier and with cetera, positioned be-j these blowers, motors, et tween the two apparatus.

It will be understood that the vario'us' mecha I nisms described as forming part of the'present apparatus may be used either together asde- J scribed, or as portions of other article handling apparatus. Y 1
