PAUL W. SCHUBERT, OF SEATTLE, WASHINGTON.

CAN-FEEDER FOR RUNWAYS.

To all whom it may concern:

Be it known that I, PAUL IV. SCHUBERT, a citizen of the United States, and resident of the city of Seattle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Can- Feeders for Runways, of which the following is a specification.

My invention relates to an improvement in can feeding devices for runways of such machines as can labelers and others in which the cans are caused to run in succession down a runway in order to present them singly to labeling devices or other mechanisms which are to act thereon.

The object of my invention is to facilitate the transfer of cans from trays or boxes to the runways of such a machine.

My invention comprises the novel parts and combination of parts which will be hereinafter particularly defined in the claims.

In the accompanying drawings I have shown my invention embodied in a simple type of apparatus, and yet of a form which is now preferred by me.

Figure 1 is a plan View of my device. Fig. 2 is a side elevation. Fig. 3 is an end elevation.

There are numerous types of apparatus used in canning establishments or plants where cans are used to hold a commercial product in which the cans are presented to the operating parts by rolling down a runway thereto. My invention relates to means by which these cans may be quickly and accurately transferred from boxes or crates to the runway. It has heretofore been the custom in many places to transfer the cans from the crates or trays to the runway by hand, the party doing this picking up two or more cans at each time with each hand. This process is slow and requires considerable expenditure for labor as well as often slowing down the operation of the machine by reason of the inability to supply it with cans with sufficient rapidity.

The device which is herein shown enables a full tray or crate of cans to be placed in position for the runway at a single operation. This mechanism consists of the following parts: A supporting frame 1 has a table or tray 2, hinged thereto by hinges 10, the axis of these hinges being preferably located upon the long side of the tray, a short distance from one corner, as is clearly shown in Fig. 3. The tray 2, in its normal position Specification of Letters Patent.

Application filed December 28, 1910.

Patented July 25, 1911.

Serial No. 599,758.

Within this tray is ed, when the tray is in its normal position,

to register with the runwayfi fso that cans placed upon the track 22, will run down the same and be directed into place upon the runway. The larger part of the outer face of the tray 2 is open. At the end next to the runway a portion thereof is covered by a plate 24, which is preferably of sheet metal and has its outer edge slightly bent outward to better insure guiding the cans into place in the runway. This curved edge is indicated in Fig. 1. This same section has an inclined top wall 23, which at the end from which the cans emerge, is at a distance from the inclined track 22, to correspond with that of the top 30 of the runway section 3. The tray or table 2, by reason of the hinges 10, may be swung from the vertical position shown in the drawings, to a position which is substantially horizontal, or into contact with the stop blocks 11. Normally, it will be in a position shown in the drawings. When in this position a tray or crate of cans, in which the cans are only one layer deep, is placed upon the trackway 22, with the side of the tray downward and the open top of the tray facing toward the back 20 of the hinged tray 2. In this condition the tray 2 is thrown backward and into a horizontal position, or until it contacts with the stops 11. When in this position the transfer tray or crate is bottom-side up and may be easily lifted off of the cans, which is done. This leaves the cans in the hinged tray 2 standing upon their ends. This tray is then swung upward into the vertical position, whereupon the cans roll downward into the section covered by the plate 24 and are guided into the runway 3. In this manner the transfer of a tray of cans to the runway is a very short and simple operation. In practical use it has been found that the services of one man for transferring these cans is entirely dispensed with, and in addition to this it is possible to speed the labeling machine up so as to obtain approximately a 50% larger output from the same machine. The section 3 of the runway, which is covered, is shown as having top bars 30, which are slightly converging relative to the bottom bars, toward the discharge end, and communicates with the runway 31 of the labeling machine.

hat 1 claim as my invention is:

1. A can feeder for runways comprising a tray-holder hinged to swing into a horizontal or vertical position and having a can-discharging opening at one end, and a side which is inclined toward the discharge opening when this side is down.

2. A can feeder for runways comprising a tray-holder hinged to swing into horizontal and vertical positions, having one of its larger sides, in the main open, and a smaller side inclined toward the discharge end when this side is down, said discharge end being inclosed and with the side opposite said inclined side converging thereto and provided with a discharge opening between said sides.

3. A can feeding device for runways comprising a stand or support, a receiver for a tray or box of cans, hinged to the corner of the support, the hinge being located upon the receiver inward from the corner thereof, whereby the receiver may be swung into either a vertical or horizontal position and the sides of the support or stand will act as stops limiting the swing of the receiver.

In testimony whereof I have hereunto afiixed my signature at Seattle, Washington, this 22nd day of December, 1910.
