CAN-.LABELING MACHINE.

SPECIFICATON forming part of Letters Patent No. 514,705, dated February 13, 1894. Application iiled Januaryl, 1893. Serial No. 458.574. (No model.)

To a/ZZ whom it may concern:

Be it known that I, EVAN W. CORNELL, a citizenoftheUnited States, residingatAdrian, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvementsin Can-Labeling Machines; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to thelettersand figures of reference marked thereon, which form a part of 4this specification.

This invention relates to an improvement in can labeling machines and consists in producing a machine of this class that is adapted to beactuated by thegravity of the lled can, and in which the label is applied to the cau as it rolls from one end of the machine to the other, as will be hereinafter more fully set forth, the essential features of which being pointed out particularly in the claims.

The object of the invention is to provide a simple, cheap and effective machine for labeling cans, and in which the-arrangement is such that the machine is actuated by the gravity of the cans, and the labels are applied thereto as said cans are caused to roll from one end of said machine to the other. This object is attained by the mechanism illustrated in the accompanying drawings, in which- Figurel is a perspective view of my iinproved machine. Fig. 2 is a side elevation of same. Fig. 3 is a vertical longitudinal section through Fig. 2. Fig. is a detail in perspective of the label containing receptacle, showing a can passing over said labels and causing .one to adhere thereto. of one of the restraining knives of the label receptacle, which are adapted to engage opposite edges of the labels, and so confine them in said receptacle that but one will be detached at a time as the can passes over them.

Referring to the letters and figures of reference, A designates the frame of the machine having an inclined table. Upon said table is mounted the can run-way consisting of a 5o trough or chute having the vertical sides B. Located at the forward end of the chute or run- Fig. 5 is a detailway is an abruptly inclined andoscillative section C, which is hinged at a to the main portion of the run-way and is adapted to swing down-` ward by the weight of the can when placed thereon. Said section being provided with the opposite guides b between which the cans are placed and which serve to bring said cans into proper position for starting on their course through the machine. Leadingfrom the guides b are the tracks c which connect with the tracks c' on the sides of the main chuteuipon which the cans are adapted to roll between the guides d, which guides are made adjustable to accommodate the various lengths of cans, by means of the movable stops d.

E designates thepaste-pot which is located between the oscillative section C and the label receptacle D. Within said pot near the bottom thereof, is'a roller F which is mounted on a shaft passing through said pot and carrying a gear wheel G which meshes with the gear G on the shaft of the roller F', journaled-in the pot above the roller Fand running in-peripheral contact therewith. Crossing the interior of the pot adjacent to the periphery of the roller F is a scraper F which prevents too great au accumulation of paste on the surface of said roller.

The roller F supplies the paste to the roller` F which is provided with a covering of felt, and extends between the track so as to apply paste to aportion of the periphery of the can as it passes along said track.

To provide for rotating the paste rollers, the oscillative section of the run-way is provided with an arm f, to the upper end of which is pivoted. a ratchet if', which engages the teeth of the gear G, whereby, when said section is depressed, said ratchet will actuate l said gear and revolve the rollers F, F', thereby, applying the past in proper proportion to the cans as they pass over the roller F. The section C is returned to its normal position after being depressed, by means of a weight f, which is attached to one end of apivoted lever h, which is coupled at its other end, by means of the bar h with the under side of said oscillative section, as clearly shown in,

Figs. 2 and 3.

The label receptacle is provided with lat- IOO eraliy adjustable sides h, so as to accommodate various widths of labels, said sides being adjusted by means of the hand screws t', that engage the angle-irons t attached to said sides. Forming the bottom of said receptacle, is a vertically movable follower H upon which the labels are placed and which is adapted to be forced upward by means of a weighted cam Il which engages the lower end of an arm H, depending from said follower.

In applying glazed or stiff labels to the cans, it is found necessary to moisteu the lap ends thereof before they are placed in the receptacle, to render them soft and pliable so as to enable the paste to hold said lap ends in perfect adhesion to the can. This moistening of the labels causes the pack or bunch to become thicker at the nioistened end. It is necessary therefore in ord er to keep the bun ch of labels level, that the feed shall be greater at this end. To accomplish this, the follower His provided with the curved arm Il that passes through a closely fitting guide 2 secured to the frame, causing said arm to travel in the arc of a circle, which gives the follower a tilting motion and carries the lower end thereof, upon which the wet ends of the labels rest, faster than the uppei1 end.

To provide for lifting the bottom ll of the label receptacle so that the surface of the labels therein may be maintained on a level with the plane of the chute or run-way, the arm I-I" is not attached directly to the bottom H, but to a bar k hinged at one end to said bottom and having at the other end a thumb screw k passing therethrough and bearing against the under face of the bottom, whereby, by turning said screw, the bottom may be tilted as desired.

Projecting laterally into the label receptacle from each side thereof, are the opposed V-shaped knives m which are formed on the end journals n, as clearly shown in Fig. 5, the cutting edges of said knives terminating at or near the circumferential center of said journals which are adapted to be slightly rotated by means of the arms o attached thereto and which are coupled by the connecting bars o to the arms f, whereby, by the oscillation of said section C, the journals n will be rotated causing the knives to work upon the uppermost labels, which are forced upward against said knives by the weighted cam H and cut through the edges thereof, the wedge shape of said knives preventing the cut labels from crowding past them and retaining them in such position that they may be readily picked up, one at a time, by the paste upon the cans, as said cans roll over them. The :resistance of the bevel of said knives being sucient to prevent the succeeding label from being drawn after the topmost label as it is detached by the rolling can.

The can in passing over the paste roller G has paste applied to a portion of its periphery, and said roller is so adjusted with respect to the label receptacle, that as the can rolls along, the center of its pasted portion will strike the forward end of the uppermostlabel, so that said label will be picked up by the paste, and rolled onto the can.

To provide for applying paste to the lap end of the label, the crank rod I is employed which extends across the label receptacle and rests upon the labels therein, its ends being journaled in brackets r fastened to the sides of said receptacle. One end of said crank rod extends through its brackets and is environed by a coiled spring s, which is secured at one end to said rod, and the other end to s'rid bracket. The tension of said spring acting upon said rod, normally throws the horizontal portion thereof forward of its points of pivot, causing it to lie in one of the series of grooves a in the upper edge of the label receptacle so that as the can rolls over said rod with one end of the label attached thereto, the rod is brought between the label and the can,.as clearly shown in Fig. 4, and as the can rolls, said crank rod is swung upward by the engagement of the label therewith, in which position it remains until the can shall have nearly passed off of the lower end of the label, when the force of the spring s will return said crank to its former position, which operation quickly withdraws the free or lap end of the label from under the can, causing it to come in contact with the pasted surface thereof, and applying paste thereto. Said crank rod maybe regulated to accommodate the various lengths of the laps of the labels, by adjusting longitudinally the brackets i' in which the ends of said rod are journaled. The provision for the adjustment being shown in Fig. 1. After the can has passed from the label receptacle with the label attached thereto, it rolls onto the inclined apron J and the succeeding revolutions of the can down said apron, cause the lap-end of the label to firmly adhere. The operation of attaching the label being complete when thc can is arrested by the stop K at the bottom of the chute. This apron J is composed of a series of flexible strands that are stretched longitudinally between the sides B, their lower ends passing over and secured to a drum L journaled between said sides, the shaft of said drum carrying on its outer end a ratchet wheel M adapted to be engaged by a pawl 't whereby the proper tension may be applied to said strands. The upper ends of said strands pass over an inclined brace 3 secured between the sides B, and are attached to a transverse rod 4, below the end of said brace. The elastic nature of these strands because of the tension placed thereon causes them to spring and vibrate as the can rolls along, and being independent of one another, they conform more perfectly to and act upon alluneven surfaces thereby thoroughly pressing the label upon the can.

The lowerl end of the run-way is supported upon a roller N journaled in brackets P secured to the table, so that the portion of said run-way below the label receptacle may be ICO IIO

drawn away therefrom to enable the labels to be readily placed in said receptacle or removed therefrom, the upper end of the movable section being supported upon a cross piece P which is secured to the chute or runf way and is adapted to slide therewith, being secured by a bolt U passing through a slot o therein and receiving a thumb-nut z. The brackets P are provided with vertical eXtenro sions 5, which bear against rubbing plates 6 secured on each side of the chute, and guide it in its longitudinal movement.

The cans may be fed to this machine rapidly and caused to follow each other in quick succession, so that there may bea continual train of cans passing through the machine.
