MACHINE FOR APPLYING CORNER-STAYS TO BOXES.

SPECIFICATION forming part of Letters Patent No. 438,546, dated October 14, 1890.

Application filed April 4, 1890.

have invented new and useful Improvements in Machines for Applying Corner-Stays to Boxes, of which the following is a specification.

This invention relates to a machine for applying corner-stays to boxes, such cornerstays being cut into the required length and width and placed into aholder, then rendered adhesive one after the other, and finally secured to the box by pressure, as fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a sectional front elevation of the machine, showing the parts in their position of rest. Fig. 2 is a similar view showing the parts in a position different from that shown in Fig. 1. Fig. 3 is a vertical section in the plane :0 m, Fig. 1. Fig. 4 is a perspective view of the holder. Fig. 5 is a perspective view of the picker. Fig. 6 is a perspective view of a box provided with corner-stays. Fig. 7 is a perspective View of one of the corner-stays. Figs. 8 and 9 are a sectional elevation of a modified form of a picker, said figures being drawn on a larger scale than the preceding figures. Fig. 10 is a side view of Fig. 9, drawn to the same scale as said figure.

Similar letters and figures indicate corre sponding parts.

In the drawings, the letter A designates a table supported upon legs A, and from which rise two standards A which contain bearings for a cam-shaft O.

B is the box-support, which is firmly secured to the table A, and the sides of which are inclined to fit the corner of the box W.

The corner-stays a are made of paper,

. muslin, or any other suitable flexible material,

and they are cut out to correspond in length and width to the size of the box to which they are applied. These stays may be introduced into the machine in a plain state and afterward rendered adhesive by the application of the paste, or said stays may be pre- Serial No. 346,513. (No model.)

viously prepared by coating one side of each stay with a suitable adhesive-such as mucilage-which is left to dry, and if such previously-prepared stays are used they are afterterward rendered adhesive by the. application of moisture.

The stays, whether plain or previously prepared, are formed into a pile and introduced into a holder G. A perspective view of this holder Gis shown in Fig. 4. It is composed of a bottom 0 and two end plates 11, which are adjustable on the bottom, and the upper ends of which are bifurcated. The extremity of each member of the bifurcations is provided with a hook 6, so that each end plate has two separated hooks to bear against the uppermost corner-stay and thereby retain the column or stack more accurately in position than where a single hook is provided on each end plate. On the bottom 0 is placed a spiral spring f, which forces the piles of stays up against the hooks e.

On the table A are cast or otherwise secured two plates g, to which the holder G is attached by screws h. In front of the tableA are situated two guides H H, between which is fitted the cross-head I, and in this eross-headisfirmly secured a stud 2', which forms the fulcrum for an arm J. The inner end of the arm J carries the picker L, which has a recessed face corsupport. On the bottom of the picker are fiat surfaces Z Z, which are provided with teeth that bite into the uppermost stay when the picker is depressed and withdraw the same from the holder. The linear movement of the picker L is produced by the combined action of a lever M and a drum N, containing a cam-groove O. This lever has its fulcrum on a stud m, secured in one of the legs A, supporting the table, and its upper end engages with the stud 'i in the cross-head I. A rollerstud n on the lever M engages with the cam-groove O of the drum N, which is mounted on the shaft P of the weighted foot-lever P. On the top of the foot-lever is formed a toothed segment Q, which engages with a geai wheel q, mounted on a spindle Q. This gear q engages with gear q, mounted loosely on the cam-shaft C. The gear-wheel q is coupled to the shaft so as to rotate the same in the direction of arrow 1, Fig. 1, only, by any well-known form of clutch R. A ratchet-wheel r and pawl 'r prevent the accidental turning of the shaft in the wrong direction by friction between the same and the gear-wheel q. On the shaft are rigidly mounted three cams S T Uone cam S above the box-support, one T above the fount V, and one U above the holder G. In the fount V is a device W, which serves to transmit paste or moisture from the fountV to the stay, and which I shall hereinafter term the transmitter. The transmitter is made of an absorbent material-such as spongeand I prefer to make it in the form of a roller; but it may be in the form of a pad. If a plain stay is used, the fount is supplied with past e; but if a previously-prepared stay is used the fount is supplied with water, so that one side of each stay being pressed down upon the transmitter WV is rendered adhesive.

The cam-groove O for actuating the lever M has three straight or parallel portions 1, 2, and 3, which cause the picker L to stop when it is over the holder G, the transmitter W, and the box-support B, respectively, and it has oblique portions 4 and 5, which cause the picker to be moved from the holder to the transmitter and from the latter to the box-support. The foot-lever P being pressed back,

' the drum N is turned in the direction of arrow the picker down upon the transmitter and the stay is rendered adhesive. The cam T having passed the picker, it is carried to a position above the box-support B. The descending cam S now engages with the picker and causes it to lay the stay upon the corner of the box Fig. 2. The foot-lever P being released, it is carried back to the position shown in Fig. 1 by the action of a weight,

spring, or other well-known means. During this half-vibration the cam-shaft 0 remains stationary, it having made one complete rotation in the former half-stroke of the footlever.

Springsj on each side of the picker-arm J tend to hold it in an elevated or normal condition.

In Figs. 8, 9, and 10 I have shown a modified form of the picker L. This picker embodies in its construction two clearing-wings L L, which are intended to remove the corner-stay a from the teeth of the picker when the picker is over the box-support B and is descending on the box. To this end the wings L L are hinged at b to each side of the picker and the teeth b b are secured in the body of the picker, but project through suitable openings beyond the lower surface of said wings, so that they can penetrate the stay, as seen in Fig. 8. To the' outer ends of the wings L L are connected the lower ends of rods 0 c, which are connected at their top ends by a bridge 0. Springs 0* normally hold the wings in the position shown in Fig. 8. When the bridge 0 is engaged by the cam S, the rods 0 are depressed and the wings are turned downward to strip the stay from the teeth 11 b WVhen a picker of this construction is used,it is so fed forward to the holder G and the transmitter W that the two cams T and U above the same engage with projections 25 on the picker instead of with the bridge 0.

By the use of the clearing-wings L L all danger of tearing the stay is avoided.

A suitable gage K, consisting of a flat plate, is secured to the table A, Figs. 1 and 3, by a bar and screw 70. The gage may be adj ustable in the direction of the depth of the boxsupport B and forms a rest for the top of the box.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the box-support, the holder G, the fount, and its transmitter W, of a picker L, arranged to move across the box support, the holder, and the transmitter, and cams arranged above the support, the

holder, and the transmitter for depressing the picker, substantially as shown and described.

2. The combination, with a box-support, the holder, the fount, and its transmitter, of a picker L, cams arranged to engage with said picker, a turnng drum containing a cam groove 0, provided with straight and oblique portions, and a lever-connection between the picker and the drum for actuating the former, substantially as shown and described.

3. The combination, with the box-support, the holder, the fount, and its transmitter, of a picker L, a cross-head having a pivotal connection with the picker, a drum containing a cam-groove O, a lever-connection between the cross-head and the cam-groove, a cam-shaft having thereon cams for engaging with the picker, and a lever geared to the cam-shaft for rotating the same, substantially as shown and described.

4. The combination, with the box-support, the holder G, the fount, and its transmitter W, of the spring-supported hinged picker L, a rotary drum containing a cam-groove O, a lever-connection between the picker and the groove, a cam-shaft C, cams arranged on said shaft above the support-holder and the transmitter for successively engaging with the picker, and a lever P, rigidly secured to the drum-shaft and geared to the cam-shaft, subon said shaft, a clutch R, and a lever P, for actuating the gear q, substantially as shown and described.

6. The picker L, having a recess the stationary walls of which converge toward the bottom of the recess to correspond with the box-corners and are provided with flat bottom surfaces Z, each carrying a line of teeth, substantially as and for the purposes described.

7. The picker L,having the clearing-wings L L, and the teeth I) 17, extending through said clearing-wings, substantially as shown and described.
