Tracks 26 which may be formed of angles as indicated are provided for supporting the belt and to cooperate with the aligning memare mounted in staggered relation, the drive pulleys being secured on a shaft 1 which is rotatably mounted in bearings 32 and the idler pulleys being secured on a shaft 33 which is rotatably mounted in bearings It will be noted that the drive pulleys for belts 15 and 16 are located at the left hand end of the machine and for belt 17 at the right hand end, viewing Fig. 1. I

The return portion 35 of the belt is supported on idle rollers 36 which are rotatably supported on a shaft 37 which is mounted in brackets 38 secured to the standards 28.

r The can transfer means consist of

thin disks

39 and 40 which are secured at the upper end of spindles 41 which in turn are rotatably mounted between the belts in bearings 42 mounted on legs 28. A. bevel gear 43 is secured to the lower end of the spindle for driving the disk which is in contact with the beltat all times, the disk having a sharp peripheral edge 44.

The cans are raised onto the disk by cooperation with a finger 45 or roller 46. which are fixedly secured in a position between the belts.

The heating system consists ofsteam pipes I 47 and 48 which are provided with apertures 49 in the side through which steani' is permitted to escape into the cabinet and which is directed against the sides of the cans, the pipes coincidentlyforming guards or guides for the cans and having one end flatted and arouately formed as at 50, and being oppositely disposed, each set being connected by headers 51 which are connected by a suitable supply pipe 52, the portion adjacent the headers also being arcuately formed as at 53, the portions and 53 being adapted to shift the cans into cooperation with the cam fingers 45 or roller 46.

A modification of the can shifting means is shown in Fig. 8 in which the portion is replaced by an adjustable cam '54, the cans f; cooperating with the edge 55 and being thus urged over onto the roller 46 orfinger 45.

Slots 56 permit suitable adjustment for different size cans.

The intake and discharge means are disposed on opposite sides of the machine and consist of the intake disc 57 and discharge disc 58 which are similar to the

transfer discs

39 and 40, theintake disc requiring no cam finger while the discharge disc hasa finger 45 for raising the cans onto the disc.

of the groove as shown at 61 to prevent kinking of the belt at the riders, and consequent crystallization of the metal at those points.

The drive for the machine consists of a motor 62 which through suitable reduction gearing drives one of the drive pulley shafts 31, which has a bevel gear 63 secured thereon, which cooperates with a bevel gear 65 on a shaft 66, which through a pair of bevel gears 67 drives the pulley at the other end of the machine. a

'The intake and discharge discs are mounted on spindles 68 which have a bevel gear 69 secured thereon which cooperates with a bevel gear 64 on the shaft 31.

The transfer discs are driven by a pair of spiral gears 70 and 71 respectively mounted on the shaft 66 and on a transverse shaft 7 2, on the other end of which a bevel gear 7 3 cooperates with the bevel gear 43.

All bearings are outside the heating zone or cabinet, which is formed with sides 74,

ends 75, top 76 which is removable and bottom 77 slopes both ways toward the center where a drain 78 is provided.

The lower cabinet consists of downward extensions 79 of the sides, ends 80, which continue into a guard 81 passing about the pulleys and connecting with the ends 75. An opening through the machine transversely is'provided for the transfer disc drives and consists of top ends 82 and bottom'83, which seal off this opening from the cabinet. The

bearings 38 are mounted on the standards outside the cabinet as shown. as are also the pulley bearings 34. It will be noted that the only openings in the cabinet to the interior are the intake passage-at one end and the discharge passage at the other'end.

The direction of travel of the discs and belts are indicated by arrows in Fig. 1. The cans are placed on disc 57 by which they are transferred to belt 15, traveling to the left as viewed in Figs. 1 and 2 and after reaching a point adjacentthe transfer disc 40 are deflected by the portion 53 of the steam pipe or the cam 54 onto the finger 45 which raises one side of the can sufficiently to ride on the disc, which carries them about and deposits the cans 86 on the belt 17 which runs in the opposite direction to belt 15 again transferring them by means of disc 39 to belt 16 from be notedthat variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.
