This invention relates to a centrifugal can 6 Claims.

ular predetermined relation operations for use in canning The general object of the invention is to provide means whereby cans placed in a pile on a rotating member are moved by centrifugal force upon single iile conveying means which may preferably take the form of another rotary member which conveys the cans in lengthwise position through a chute which deposits cans to .a gravity chute, in rolling procession, with meansA whereby any can moving onto the second rotary member in improper position will be turned to proper position on the second member.

This invention also consists in certain other features of construction and in the combina-tion and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views and in which:

Fig. 1 is a top plan view of the device.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a view of the bumper member.

Fig. 4 is `a view of the tripper.

In these drawings the letter A indicates a base to which is secured an upright bracket I which rotatably supports a shaft 2 which is vertically arranged `and which is surrounded by a hollow shaft 3 which is also rotatab-ly supported by the bracket I A disc 4 is connected to the upper end of the hollow shaft 3 and a convex disc 5 is connected to the upper end O the shaft 2, this disc 5 being arranged above the disc 4 and being much less in diameter than the disc 4 and concentrically arranged in relation thereto. A pulley 6 is connected to the lower end of the hollow shaft 3 and a pulley 'I to the shaft 2, belts 8 passing over these pulleys and over the pulleys 9 on a shaft I!! supported by an upright bracket I I from the base A, the shaft being driven from any suitable source of power through means of the pulley l2 and the belt I3.

These parts are so arranged that the flat disc 4 revolves faster than the convex disc 5.

Thus, the disc 5 forms a rotary table to receive indiscriminately positioned cans and effect outward movement of such cans ontf:l the projecting portion of the disc 4 which provides conveying means to receive and carry the cans in single file andin end toV end relation to a discharge point.

Because of the dif- (Cll. 198-33) ferential speed provided between discs 4 .and 5, cans on disc 5 can move or roll outwardly thereof and find their place on disc 4 without interference or jamming.

A substantially circular guide rail I4 is spaced above the two discs and acts to guide the cans to the chute B which is comprised of the top rail I5 and the side rails I6 which Aare connected together as shown at Il. The inlet end of the chute B flares as shown in Figs. 1 and 2 so that the cans can readily enter the same and said chute is provided with a substantially horizontal inlet portion and with .a depending exhaust portion which discharges the cans upon a gravity Chute C. The depending' portion of the chute B is wider as shown in Fig. 2 so that the cans entering the chute in endwise position can turn to fall upon the gravity chute C upon their sides in rolling procession, as shown in dotted lines in Fig. 2. In order to facilitate this turning of the cans in the depending portion of the chute B, I provide a bumper member I8, as shown in detail in Fig. 3 and including 4a shank and a cross head I8 which engages the corners of the descending cans as shown in dotted lines in Fig. 2. The shank is pivoted intermediate its ends to a part of the chute by a pivot pin passing through the hole I9 in the shank and said shank is provided With a plurality of holes 20 for receiving a hoo-k on a spring 2| which normally holds the head i8 in raised position and permits the head to move downwardly when struck by a can so that this member acts as a bumper to take the jar off cans and also acts to cause the tilting action of the cans as shown in dotted lines in Fig. 2, whereby the cans are repositioned from their end to end relation in the discharge chute B into a rolling procession on the gravity chute or conveyor C.

As stated above, the tendency of the cans moving outwardly of the disc 5 is to roll until stopped by the guide rail I4 in end to end relation on the disc 4. Some cans, however, may move outwardly'so as to be received by the disc conveying means 4 with their length crosswise thereof, and means is provided for repositioning such cans into end to end relation on the conveying means. A bracket 22 is attached to the guide rail I4 and carries an inwardly extending V-shaped member 23 to the innerl end of which is adjustably connected a bar 24 to which is pivoted a substantially L-shaped tripper nger 25, the pivot pin` of which is shown at 26. A spring 2l surrounds and is connected with the pivot pin and has one end connected to a bracket 28 on the arm 24, the

spring acting to hold the finger in the position 'shown in Fig. 1. Thus, the tripper finger 25 and the parts associated therewith provide yieldable means for repositioning any cans which have their ends engaged with the guide rail I4 into end to end relation on the disc 4.

The cans are dumped on the convexed disc 5 from a belt or by any other means and the ro:- tating disc 5 causes the cans to move outwardly under centrifugal force upon the exposed portions of the disc 4. Most of the cans will pass upon the disc 4 against the rail I4 in lengthwise position with their side portions engaging the rail. However, some of the cans will have their ends strike the rail as shown to the right in Fig. l and as soon as they strike the tripper finger 25 they will be caused to turn to endwise position as shown to the left in Fig. 1. CansI after passing the tripper finger are moved by the disc 4 into the chute B through which they travel and drop upon the gravity chute C, the cans being turned by the bumper member I8 in the lower part of the chute B so that they fall upon the member C on the sides and will thus roll down the same.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:
