To all whom it may concern:

Be it known that I, JOHN RITTY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Machines for Folding the Ends of Wrapper-Labels Against the Ends of Cans; and I do declare the following to be a full, 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 the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a machine for folding wrapper labels over the ends of cans.

The object of the invention is to provide a machine of the above type having a capacity for neatly folding wrapper labels over the ends of cans and for locking the ends of the wrapper labels so folded, so that the possibility of the folded ends becoming loose is ob-. viated.

The invention comprises a head containing a cluster'of folders or fingers, which, in their first operation, engage the projecting end of the can label or wrapper at the circumferential edge of the can and flute or crimp said end of the label or wrapper, after which the cluster head is rotated to cause the folders or fingers to crease the end of the label or wrapper and to fold it against the end of the can. A

Preceding a detail description of the invention, reference is made to the accompanying drawings, of which I Figure 1 is a top plan view of my improved machine for folding the ends of wrapper labels over the ends of cans. Fig. 2, is a side elevation with the cluster head shown in section and a projected end of the label or wrapper broken away.- Fig. 3, is a longitudinal sectional view of the machine showing the positions of the folders or fingers after the end of the label or wrapper has been crimped or fluted against the end of the can and before the cluster head is rotated to cause said fingers to crease said end of the label. Fig. 4, is a rear elevation of the machine. Fig. 5, is an elevation of the cluster head showing the foldcrs or fingers thrown out to the position shown -in 3. Fig, 6, is an elevation of the cluster of fingers in the positions shown in Fig. 3, and in which the proj ected end of the label or wrapper is fluted or crimped and -is ready for creasing. Fig, 7, is a view of the end of a can showing the completion of the foldingof the end of the label or wrapper there-against.

The mechanism acting directly upon the projecting ends of the labels, comprises what is termed a cluster head, consisting of a concentric cluster of folders or fingers 1, which are pivotally mounted around a head I 2. These fingers so clustered or grouped point to a common center when thrown out of the head as in Figs. 3 and 5, and are preferably cone-shaped. It is necessary that said folders or fingers be pivoted in order that they may assume the respective positions shown in Figs. 2 and 3.

A desirable form of pivot consists of a series of bearings 3 into which the shanks 4 of the fingers are projected and adapted to turnfreely therein when the folders or fingers are carried around by the rotating head. Extending at right angles fromthe bearings 3 are pins 5 which have bearings in sleeves 6, said sleeves being fast on the head 2. It will thus be seen that the folders or fingers will have independent rotary movement in the bearings 3, and the bearings 3, together with the fingers will swing on the pins 5.

Pivotally connected to the bearings 3, are links 7 p which are also pivoted at 8 to a spider .9, said spider having an extended tubular shaft 10 in line with the hub 11 of the cluster head 2. The said shaft 10 receives a shaft 12 upon the end of which said head 2 is rigidly connected. The spider 9 is splined upon said shaft 12. Owing to this manner of mounting the head 2 and the spider 9, the spider 9 may have longitudinal movement on the shaft 12 while the head 2 may not have such longitudinal movement, and both the spider 9 and the head 2 may be rotated together.

The cans to be operated upon may be held in alinement with the axis of the cluster head by any suitable means, such for example, as two semi-cylindrical members 14 and 15 which are hinged on one side and form a jacket which supports the can with the projecting end of the wrapper label in a position to enter the axis of the cluster head as shown in Fig. 2. The cluster head is moved up to receive the end 16 of the wrapper label as shown in Fig. 2. The cluster head, and the spider 9 are moved to such position by the lever 17 which carries a shifting fork 18 adapted to move the spider 9 by entering a peripheral recessin the shaft 10 thereof. The shaft 12 to which the head 2 is fixed passes loosely through the elongated hub or shaft 10 of said spider but is splined thereto, and the end of said shaft 10 is recessed as at 19 to receive a spring 23 which incloses that end of the shaft 12. In moving the spider shaft 10 forward by the lever 17, the head shaft 12 is also moved forward as shown in Fig. 2, the dotted line representing the position from which the lever 17 was moved. The tubular shaft 10 of the spider 9 and the inner shaft '12 of the head 2 are practically united by the spring 23 when moving forward to receive the end of wrapper label in the head. The rear end of the shaft 10 has a bearing 20, and the portion of said shaft opposite said bearing 20, has splined upon it a bevel gear 2]. which is inclosed in a bearing 22. The lever 17 which engages through its fork the shaft 10 has its fulcrum at a suitable point, for example, 17; when said lever is moved forward from the dotted position in Fig. 2, to

' placed in the upright position,

the full position, the cluster head and the spider 9 are moved in unison as before stated. From this position rearward, the spider 9 has independent movement on the shaft 12, as shown in Fig. 3; this independent movement is accomplished by returning the lever 17 to the dotted position in Fig. 2.. The upper portion of the lever 17 is first moved out to the dotted position, Fig. 4. The upper end. of the lever 17 controls the position of a pivotal frame, owing to said upper end or portion of said lever being pivoted to the lower portion at 24. The pivotal frame consists of a shaft 25 which is loosely mounted in bearings 26 projected from the main bearings 20 and 22.

Fixed to the shaft 25 are two'upright arms 25 which support a rod 24 lying parallel with shaft 25. This rod 24 is in a position to be engaged by the upper end of the lever 17 when the. latter is moved to the dotted position shown in Fig. 4. The shaft 25 has an arm 27 thereon, said arm being splined upon the shaft and dropping at the proper time by gravity into the position as shown in Fig. 3 in line with the end of the shaft 12 to prevent said shaft 12 from being movedlongitudinally when the lever 17 is operated to move the spider 9 rearward to throw the folders or fingers from the position shown in Fig. 2 to that shown in Fig. 3. It will be understood that, when the upper end of the operating lever 17 is moved out to the dotted position as in Fig. 4, the arm 27 is elevated away from the end of the shaft 12, through the engagement of said lever 17 with the rod 24 of the tilting frame. When said lever 17 is the arm 27 drops behind the shaft 12. When the folders or fingers 1 are moved to their limit as shown in Fig. 3, and preparatory to the rotation of the head 2, it is essential that the end of the can shall receive no excess of pressure from said folders which might be due to the continued movement of the spider 9; this result is obtained by permitting the shaft 12 to yield against the arm 27, said arm yielding against the spring 28 for the excess of pressure required between the folders and the end of the can. In-other words, when the desired contact between the end of the can and folders takes place, the shaft 12 will move back against the tension of the spring 28. The rotary movement is given the head 2 when the folders have been moved to-the position shown in Fig. 3, by means of a bevel gear 29 upon a shaft which is rotated from a crank 30. The said shaft is supported in a bearing 31, and the bevel gear 29 engages the similar but larger gear 21 before referred to. This latter gear as before stated, is splined upon the tubular shaft 10 of the spider 9.

In the rotation of the head, the fingers or folders 1 rotate individually as before stated through the friction between said fingers and the folded end of the wrapper label, and the said fingers in addition are carried around bodily by the head to crease the folds which is done by passing said fingers over. the folds see Figs. 6 and 7. As hereinbefore stated, Fig. 6 represents the end of the wrapper label when the folding fingers 1 are moved to the position shown in Figs. 3 or 5. From this position the fingers or folders are rotated in a circle, pressing the folded end of the wrapper label flat against the head of the can creasing the folds and forming a lock at the center of the can head. -This lock is formed by the inner ends of the fingers moving withina small radius as compared with the movement of the larger or outer portions of said fingers. The projecting end of the wrapper label is somewhat longer than half the diameter of the end of the can; owing to this, when the fingers or folders are rotated they cause the inner ends of the folds to lie one over the other as shown in Fig. 7 and to thus lock each adjacent fold to the other. 1

Briefly described, the operation of the machine is as follows: A can is placed in position in the jacket or holder as shown'in Fig. 1, with the end of the label to be folded, in line with the axis of the head. The operating handle 17 having been previously moved outwardly on its pivot 24 to the dotted position Fig. 4, to remove the arm 27 away from the end of shaft 12; the lever 17 is then moved forward to cause the head 2 and the spider 9 to move together to the position shown in Fig. 2, wherein the end of the wrapper label is in a position to be engaged by the fingers 1. From this position, the operating handle 17 is moved to its upright position which permits the arm 27 to drop in line with the end of the shaft 12. The rearward movement of said lever 17 causes the shaft 10 and therewith the spider 9 to move independently of the shaft 12 and to thus throw forwardly in a uniform manner the folders or fingers 1 through the connecting links 7 to the position shown in Figs. 3 or 5, and to thus crimp or fold the end of the wrapper label. The cluster head is then rotated through the crank 30 and

bevel gears

29 and 21 to make one complete revolution, during which the end of the wrapper label is folded snugly and uniformly against the end of the can as shown in Fig. 7. When the fingers 1 are thrown out from the cluster head, for example, from the positions shown in Fig. 2, they first press the wrapper label over the circumferential edge of the can and hold said .wra'pper label at these points while said fingers are completing their folding or crimping movement in which the entire end, of the label is pressed against the end of the can. This is important for the reason that the end of the wrapper label tobe folded over the end of the can is held firmly around the edge of the can while the fingers are completing the folds or erimps, and said wrapper label isprevented from bulging out beyond the circumference of the can while being folded or crimped to the positions shown in Fig. 6.

Having described my invention, I claim;
