them one by one onto the receiving rotor seats.

Another object of the invention is'to providea conveyer or mechanism of-the character stated in which said traversing belt flight is disposed diagonally across the wide belt and in which there is included a knurled rotor spaced a distance slightly greater than the diameter of the crown caps from the delivery end portion of the traversing belt and movable reversely of the direction of movement of said traversing belt so as to be effective to prevent jamming of caps as they pass from the wide belt onto the narrow belt.

In the apparatus herein disclosed as an example of embodiment of theinvention, the cap feeding means forming the basis of the present invention is generally" designated A, and bytliis means the crown caps are fed from an assembling orspotting-macliineato the counting mechanism coveredin the herein before mentioned parent case wherein is included a cap'pressing and counter mechanism actuating unit general- 1y designated B; and a counting mechanism or unitproper designated 0*." See Figure 2;

The feeding means Aincludes'a bed frame 5 supported upon-a standard sand from which is suspended an electric motor 1. The crown caps enter the apparatus en masse or in transverse rows on their way from the assembling or spotting machine to the counting mechanism on a wide belt 8, the delivery end of which passes over a support trough 9 and over a pulley In. The pulley I0 is mounted on a cross shaft II which is rotatable in frame bearings l2 and carries a worm wheel l3 to whichrotation is imparted by a worm gear l4 mounted on-a driver shaft l5 rotatable in frame bearings IS. The shaft 15 also carries a large pulley I! which is driven by a belt I8 from the motor drive pulley l9. See Figures 1, 2 and 6.

The belt 8 feeds the caps, hollow side uppermost, under a single layer confining shelf 20 and against an aligned belt 2| disposed diagonally across the belt 8 and which turns about a tensioning idler pulley 22 at the receiving side of the belt 2| and over a driverpulley 23 at the delivery side of said belt. I The driver pulley 23 Figure-7"i'sa fragmentary'vertical cross seci rotates in close proximity to the belt 8 and is carried at the lower end of a vertical shaft. 24 rotatable in bearings 25 and driven through a bevel gear couple 26 by a driver shaft 21. See Figures 1, 2 and'6. The shaft 21 is rotatable in bearings 28 and is equipped with a pinion 29 to which rotation is imparted through an idler gear 30 from a driver gear 3| mounted on the cross shaft I l.

A knurled rotor 32 is opposed to the delivery end of the aligner belt 2|, being spaced therefrom a distance just in excess of the diameter of the crown caps so as to cause'the caps to pass in single file between said rotor and belt without jamming. The rotor 32 is mounted at the lower end of a shaft 33 rotatable in the vertically disposed frame bearing 34 and driven by bearings 4| and having a worm gear 42 mounted thereon to which rotation is imparted by a worm gear 43 fixed upon a shaft 44. The shaft 44 is rotatable in frame bearings 45 and is releasably drive coupled, as at 46, with the shaft 15 hereinbefore referred to. See Figures 2, 3 and '7.

The shaft 44 also carries a worm gear 41, which meshes with and imparts rotation to a worm wheel 48 mounted on a shaft'49 rotatable about a vertical axis in a bearing 50 in the casing unit 5| and which carries a spur gear 52 at, its' lower end and which serves to drive the turret or rotor 53 of the unit B by meshing with the rotor drive gear 54. See Figures 2 and l.

At its delivery end, the conveyer belt 3'! delivers the crown caps one by one into the peripheral pockets of a distributer disk 55 which is adjustably aflixed to the upper end of a sleeve 56 rotatable about a stud shaft 51 fixed vertically in a frame bearing 58. The sleeve 56 carries a spur gear 59 to which rotation is imparted by the turret or rotor gear 54 to which, in turn, rotation is imparted by the gear 52 previously referred to. See Figures 2 and 5. While traveling about in the pockets of the distributer disk 55, the crown caps are retained by a surrounding wall 60 which extends to the discharge point Bl at which the crown caps are delivered one by one onto the seats 62 of the rotor 53 of the cap pressing, counter mechanism actuating unit B.

It is of course to be understood that the details of structure and the arrangement of parts may be variously changed and modified without departing from the spirit and scope of the invention. We claim:

1. In crown cap conveyer means, a wide conveyer belt on which caps are fed side by side, a second conveyer belt having a flight disposed transversely over said wide belt for intercepting caps fed by said wide belt and moving them laterally over said wide belt to one side thereof, a narrow belt disposed to receive caps fed laterally on said wide belt and convey them single file away from said wide belt, and a diverter wall extending continuously and diagonally across the full width of the wide belt in advance of said second conveyer flight and a distance thereabove slightly greater than the thickness of a crown cap thereby to be effective to directly' contact and strip off laterally any caps being conveyed by the wide belt in superposed relation.

2. In crown cap conveyer means, a wide conveyer belt on which caps are fed side by side, a second conveyer belt having a flight disposed transversely over said wide belt for intercepting caps fed by said wide belt and moving them laterally over said wide belt to one side thereof, a narrow belt disposed to receiv caps fed laterally on said wide belt and convey them single file away from said wide belt, said second conveyer flight being disposed to traverse said wide belt diagonally, a knurled rotor rotating in a direction opposite the direction of travel of said second conveyer flight and spaced a distance slightly greater than the diameter of a crown cap from the end of the second conveyer flight where it delivers onto said narrow con veyer so as to prevent jamming of caps as they are being delivered onto said narrow conveyer, and a diverter Wall extending continuouslyand diagonally across the full width of the wide belt in advance of said second conveyer flight and a distance thereabove slightly greater than the thickness of a crown cap thereby to be efiective to directly contact and strip ofi laterally any caps being conveyed by the wide belt in superposed relation.
