Application filed August 30, 1915. Serial No. 48,089.

To all whom it may concern:

Be it known that we, JOHN L. WHITE- HURST and CHARLES H. W111), citizens of the United States of America, residing at Baltimore, Maryland, have invented certain Improvements in Machines for Casing or Boxing Cans, of which the following 1s a speclfication.

This invention relates to certain improvements in that class of machines whereby cans automatically stacked therein, are forced therefrom into a packing case or box and in a condition for shipment, as will hereinafter fully appear. I

In the further description of the said 1nvention which follows, reference is made to the accompanying drawings, forming a part hereof, and in which Figure 1 is an exterior side view of the machine, and Fig. 2 a plan of certain parts of the same as viewed in the direction indlcated by the arrow in Fig. 1.

Fig. 3 is a sectional side view of the mechanism whereby the cans are pushed from the remaining portion of the machine into a packing case or box, not shown, together with certain other elements of the machine which cooperate with them and which are shown in dotted lines.

Fig. 4 is an enlarged side view of certam details of the machine; and Fig. 5 an end view of the same. 0

Fig. 6 is a view of certain parts shown in Fig. 1, illustrating a peculiar movement pf the cans as hereinafter described, and Fig. 7 an enlarged view of parts of Fig. 6.

Referring now to the drawings, 1 is the wheeled frame of the machine, and 2 a receptacle supported by the frame, and shown as formed of angle iron bars 3, into which cans are delivered from an ordinary runway not shown.

The bars 3 are arranged to form three channels a, b and c which are open at the top for the reception of the cans from the runway, and which serve to distribute the cans into vertical and horizontal rows; and it will be understood that in the operation of the machine the cans first enter and fill the spacea, and after that space is filled, the next space Z2 receives the cans which roll over the top can in space a, and this opera tion is continued until all the spaces are filled, when the further rolling of the cans on the runway is prevented by the stop d,

cans are discharged.

4 is an angular plate seated on the frame 1, a part of the bottom of which serves as a seat for the packing case or box, not shown, into which the cans, twelve in number, are pushed at each operation of the machine; and 5, 5 are fixed horizontal shelves, two in number, which project from the vertical portion of the plate 4 and which, together with the horizontal part of the said plate, support the delivered cans in horizontal and vertical rows, as is well shown in Fig. 1 of the drawings.

7 is a pusher whereby the twelve stacked cans at each operation of the machine, are pushed into the packing box or case, and it is shown as consisting of the vertical bars 6 and the horizontal bars f, the latter being secured to the former by the rods 9.

The pusher at its inner end is supported by the plate 4 through the medium of the rollers 9 which are journaled to lugs on the bottom of the lowest of horizontal bars as shown in Figs. 1 and 3.

The means whereby the pusher is given a forward, and a backward movement, the former to carry the cans into the packing case, and the latter to carry it away from the box, consist of a bell-crank foot lever 10 pivoted to the frame 1 at h. The short arm of the bell-crank lever is connected by a link j to the arm 13 which is hinged at its lower end to the frame, as shown in Fig. 3.

The upper end of the arm 13 is branched as best shown in Fig. '2, and the branches are'united by curved-links 2' to the central horizontal bar f of the pusher.

The forward or operative movement of the pusher is of course, efiected by the foot of the operator, while its backward motion,

when the foot lever is released, is produced by the coiled spring 14 which connects the foot lever to a part of the frame 1 as shown in Fig. 3.

It is necessary before the pusher is moved forward to carry the twelve cans resting on the shelves 5 and the plate 4 to the packing case, that the delivery of the cans from the I and not again resumed until the twelve piled receptacle 2 should be suspended, and the cans in the receptacle, and those in the runway, forced backward a limited distance to produce a space between the two sets of cans that is to say the cans on the shelves 5 and the plate 4, and those in the channels a, b, and 0 and thereby avoid friction between them, and to this end, the following described mechanism is employed.

Referring now particularly to Fig. 2, 15 is a horizontal straight bar attached to one side of the pusher 7 by means of the angle iron is, so as to have a forward and backward movement in common with the pusher, and it is guided and partially supported by the roller 20 on a lug m which is a part of the frame 1.

22 is a vertically slidingv plate situated between bar 15 and a fixed angle iron 23 (see Figs. 1, 2 and 4) havin pins 24 which extend horizontally there rom, adapted, when the plate 22 is in its highest position as shown in Fig. 4, to project into the path of the cans in the receptacle 2 and thereby prevent their discharge from the spaces a, b and c as shown particularly in Fig. 4.

The said pins also operate to push back the cans in the said receptacle a limited distance, in order that their front verticalrow will not chafe the adjacent four cans carried by the pusher when brought forward or toward the packing box, as hereinafter described.

By references to Fig. 6 it will be seen that when the pins 24 are in their lowest position, they are below the cans and therefore admit of the cans in the channels pressing against those on the shelves 5, and the plate 4, as best shown by the full lines, but as the pins 24 rise they strike the cans and push them back, as shown by their dotted delineation in that figure, for the reason that the pins in their upward movement rise to nearly the center of the cans. In other words the pins in rising not only extend into the path of the cans and prevent their discharge, but strike the bodies of the cans and push them back. In Fig. 7 the pins 24 are shown as in their highest position; and in"Fig. 6 as in their lowest position in full lines, and in their highest position in dotted lines.

The plate 22 is elevated to its highest position shown in Fig. 4, as the bar 15 moves in the direction indicated by the arrow, and by the projection 29 of the said bar engaging the roller 30, and it is so held until in the return of the bar by the pin 32 passing over the notched end of the spring-held latch 31; and it will be understood that while so held, the pins 24 prevent the passage of the cans from the channels a. b and c of the receptaole, 2 to the shelves 5 and the plate 4.

-From the foregoing, it will be understood that when the plate 22 is allowed to fall from its highest position shown in Fig. 4, the pins 24 will not only pass to below the cans in the receptacle 2, but due to the angularity of the slots 27 they will be laterally withdrawn from the cans, and they will therefore offer no obstruction to a second passage of cans to the shelves 5 and the plate 4 from which they will'be carried forward by thepusher into the packing box upon the pressing down of the foot lever, as before stated.

In the return or backward movement of the bar 15, the projection 29 at the 'end of the bar 15 comes in contact with the roller 30 which is practically a part of the plate 22, and the said plate is slightly elevated, and the pins 15 strikes the lower portion of the latch 31 and throws its upper end out of contact with the pin 32 which allows the plate 22 to fall. I

The roller 30 in falling strikes the inclined part 29 of the bar 15 as shown by the dotted lines, and the further fall of the roller and the plate 22 is a gradual one.

It will be understood that a charge of cans forced by the pusher toward the packing case, will cause a prior charge to be carried into the case, and in consequence, the case, should it hold 24 cans, will be filled in two operations of the machine. This feature however is not new and is found in prior patents.

We claim as our invention 1. In a machine for the purpose described, an open top receptacle to receive cans from a runway, having inclined bars which separate the cans delivered thereto into horizontal rows, combined with means to check the discharge of cans from the receptacle and at the same time move them backward, and then'release the cans, and a pusher to drive the discharged cans laterally from the machine.

2. In a machinefor the purpose described, an open top receptacle to receive cans from a runway, provided with inclined bars which separate the cans delivered thereto into horizontal rows, combined with a vertical bar situated at the delivery end of the receptacle having horizontally projecting pins, and means whereby the said bar is given a combined vertical and lateral reciprocating movement to prevent the discharge of the cans and at the same time force them back in the receptacle and then release them.

3. In a machine for the purpose described, an open top receptacle into which cans are delivered from a runway, provided with inclined bars which separate the cans delivered thereto into horizontal rows, combined with a vertical bar situated at the delivery end of the receptacle having horizontally projecting pins, means whereby the said bar is given a combined vertical and lateral reciprocating movement, to alternately prevent the discharge of the cans and at the same time force them back and then release them, foot-operated devices to push the cans discharged as described, laterally from the machine, and spring operated mechanism to effect the return of the can-packing devices to their original position.
