CAN FEED DEVICE.

To all whom it may concern:

Be it known that I, ALBERT R. THOMPSON, a citizen of the United States, residing at San Jose, inthe county of Santa Clara and State of California, have invented certain new and useful Improvements in Can-Feed Devices, of, which the following is a specification.

My invention relates to can-feed devices.

In the canning art, as, at-present, practised,

it has become of prime importance that the continuous and voluminous stream of cans passing through the line of apparatus shall at no point be interrupted. Senous results and loss of time follow any disarrangement of the can procession, and much care and personal supervision are given to prevent nterruption of the stream. This is particularlythe case in the matter of feedlng the cans into the stream at whatever point in the line, or in connection with whatever machine of the series, it may be necessary to supply or transfer the cans. For the sake of example, I will describe my invention in connection with feeding the cans to a cooker, though it must be understood that my device is applicable to any apparatus or machine to which it is necessary to feed cans with precision and under proper control in order to inaugurate or to maintain the canstream continuity.

The object of my invention is to provide a can-feed device which will auto-' matically supply the cans in succession under conditions of accuracy as to time and position as to insure the continuance and uninterruption of the can-stream; andto this end my invention consists in the novel can-feed device which I shall now fully describe by reference to the accompanying drawings, in which 7 Figure 1 is a side elevation, broken, of a cooker, showing in front elevation the application thereto of my can-feed device.

Fig. 2 is an end view, broken, of the same, showing my can-feed device in section. V

1 is the box of the receptacle to which the cans are to be fed. This receptacle may be for any purpose, say, for example, for cooking the canned commodity. Within the receptacle is a rotating member which in the present instance is composed of a reel 2 having around its circumference a series of Specification of Letters Iatent.

Application filed November 25, 1916. Serial No. 133,472.

spaced rails 3 parallel with its axis, and forming in connection with an exterior helically dlrected fixed rail 4 a helical'can-path. for advancing the cans through the box, in a manner now well known in the art.

The rail-reel 2 is driven from a central shaft 5 by means of a worm gear 6, worm 7 and driving shaft 8 with fast and loose pulleys at 9,

To the' feed-inlet of the box 1, is fixed a housing, comprising side walls 10, an arouate roof-hood. 11 and a b0tt0m12. The inner extremity of the hood approaches closely the path of rotation of the reel-rails 3.

13 are two spaced disks each having pefeed-turret. The disks are separated by a space greater than the diameter of the cans to be'fed, so that a can coming end on or one standing upright or otherwise disarranged or out of true will fall between. them. To make their action of thus discharging a can as delicate as possible, the disks are relatively thin plates, spaced by a distance but little less than the length of the cans they are to receive, and they lie close up to the side walls 10 of the feeder housing, which walls are separated by a distance but little greater than the length of the cans. The turret-disks are mounted on a shaft 15, and are rotated by the engagement of a toothed wheel16 also mounted on the shaft 15, which wheel is directly engaged by the reelrails 3, as shown in the detail Fig. 3. The turret-disks are so located that their path of rotation approachesvclosely that of the reel-rails, and they are so spaced from the arcuate hood 11 of the housing that a can lying in and bridging their pockets will pass freely but closely under said hood.

16 is the can-feed chute which leads down into and between the side walls 10 of the housing and directs the cans to the pockets of the feed turret.

17 is afixed discharge plate lying between 0 the disks of the feed turret. 18 1s a fixed finger disposed by contact with the cans 19, to positively deliver them from the pockets of the feed-turret into the reel-rails, and to prevent them from falling out again.

The operation of the device is as follows r-The cans indicated by 19 roll down the chute 16 and under normal circumstances of accurate alinement being guided by the side walls 10 of the housing, they en- 110 ter and bridge the corresponding pockets 14: of the spaced thin-disks 13 of the turret feed. I-ly the turret they are carried under and are guided by the arcuate hood 11 of the housing until they are successively transferred after leavin the hood, to and upon the reel-rails 3 0ft e cooker. But, if a can coming down the chute 16, should be end on or upright or twisted so that it does not. lie

exactly true between the side walls of the housing, itwillnot fall intothe pockets 14: of the closely housed spaced, thin disks 13, but will at once drop down between the two disks and, falling on the plate 17, will be rolled out of the device, thereby avoiding any possible obstruction.

It will now be seen that provision is made for the control and accurate feed of the cans, so that no obstruction of the can stream will occur. The direct power transmission from the rail-reel in the cooker to the can-feed turret, eifected through the engagement of the reelrails with the toothed wheel of the turret is of importance, in that no lost-play or back-lash can occur as would result from a gear-train. The operation ofthe rail-reel and the turret feed is, therefore, in such precise timely unison that the cans cannot be displaced or disarranged in the transfer and the stream of cans will be continuous and uninterrupted and under perfect control in its determined path. The initial insurance of each cans position in the stream, by the automatic discharge of a vitally displaced, can, due to the spaced thin-turret disks and the intervening plate 17, avoids the necessity of personal supervision and attention at this point.

I claim:

A can-feed device comprising a pair of rotatable turret-disks spaced by a distance greater than the diameter and but little less than the length of the cans to be fed, and disposed to deliver the cans to the can-path of an associated receptacle; and means for directing the cans to bridge the spaced turret-disks.
