SHOE-GUMMING MACHINE.

To all whom t may concern.'

Be it known that we, JOHN F. LA BORDE and PETER K. WILLIAMS, citizens of the United States, residing at 396 Linwood avenue and 592 South Mohawk street, respect-ively, Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Shoe-Gumming Machines, of which the foland arrangements `of parts as illustrated in the accompanying drawings, and referred 1 to and claimed in the following specification.

In the drawings we have illustrated one example of the physical embodiment of our invention, constructed according to the best mode we have so far devised for the practical application of the principles thereof.

Figure 1 is a side elevation ofso much of a machine and its connections, asis neces` sary to illustrate the invention. Fig. 2 is aV front elevation of the machine. Fig. 3 is a` view similar to Fig. 1 with parts shown in section. Fig. 4 is a plan view of part of the machine with upper hammer or pressing member omitted to disclose the die and lower, gumming, member. Fig. 5 is a plan View showing parts omitted in Fig. 4. Fig. 6 is a sectional end elevation. Fig. 7 is a sectional plan view showing automatic shutter and operating connections. Fig. 8

is an enlarged longitudinal vertical section,

showing position of automatic shutter under top covering, and the parts in position they occupy while applying the adhesive to the material.

Before specically describing the machine, a general outline of the machine and its operation may be desirable in order that a clear understanding of the invention will result.

A reservoir containing an adhesive material is employed, and a gum carrier is in- Specificatioii of Letters Patent.

closed by and movable in the reservoir. A hammer or presser member is adapted to coact with the gum carrier, and these elements are actuated by suitable mechanism, as eccentrics. In coating the work, it is fed to position to be compressed between the gum carrier and the presser.

Referring to the drawings the numeral 1 designates a reservoir. This is a metallic box provided with an opening 2 in its top near the front and formed with ears 3 as a means for attachment or support. Depending from the reservoir are a pair of brackets 4, 4, in which is journaled the actuating shaft 5, which may be rotated by means of the pulley 6, suitably driven. I

J ournaled upon the shaft 5 directly below the reservoir is the central eccentric 7 with its rod 8 projecting upwardly through the reservoir, and inclosed therein by the jacket or casing 9. The eccentric rod 9 is pivoted at 10 to the bar 11 which passes through the head 12 of the hammer 13, a spring 14 located above the head acting as a cushion to the strokes of the hammer. The hammer is guided in its vertical movement in the extension 15, which is slotted at 16 to accommodrate the web 17 of the hammer. As clearly seen in the several figures, the hainmer or presser plate is located directly over the opening 2 in the top of the reservoir 1, and the under face of the hammer or plate is provided with a cushion 18.

The gum carrier or lower member of the coating device is actuated, preferablyby the pair of eccentrics 19 on shaft 5. Each eccentric is provided with its rod 20, pivoted at 21 to a carrier arm 22. These arms pass through bearings 23 at the underside `of the reservoir, on an incline, and at their upper ends support the gum carrier 24. The gum carrier 24 is a metallic plate, formed at its underside with hollow bosses 25 for the re ception of the arms 22, and set screws 26 secure these parts together.

The upper face of the carrier is dislied, as clearly shown in Fig. S, so that a quan tity of the gum may be retained upon the face of the plate. A support 27, the outline of which is clearly seen in Fig. 4, is supported upon iianges 2S and 29 formed respectively upon the top wall of the reservoir and the gum carrier plate. This support may be varied in shape to suit different requirements, and partly closes the opening 2 in the reservoir 1. The support is cut away at its front on the curved line 30, t-hus leaving an opening through which the gum carrier may protrude when in pressing po- 5 sition. To prevent the gum or cement in the reservoir becoming thick we attach a mixer to the bosses on the carrier plate, and the passage of this wire frame 3l through the gum keeps the gum in perfect working 1o condition.

To prevent evaporation of the gumming material, and to exclude dust or other deleterious substances,`from the reservoir while the opening 2 is uncovered, we utilize an automatically operated shutter 32. This shutter is a plate conforming to the shape of the opening formed by the supports 27 and is located directly beneath and parallel with the upper wall of the reservoir. Two

supporting arms 33 project rearwardly from the shutter, and are supported and guided in the bosses 34, 34, at the underside of the reservoir cover. The shutter is actuated from the eccentric rodA 8 through the medium of the lever arm 35 which is connected by link 36 to the pivoted lever 37, one end of said lever being connected to the cross arm 38 by means of the link 39. In order to permit the gum carrier to lower, or move downwardly before the shutter begins to close the opening 2, the joint or connection between the lever arm and its link, is formed with an elongated slot 40. The actuating mechanism for the shutter is of 35 course timed with relation to the movement of the rod 8 to keep the opening 2 closed in the absence of the gum carrier, and is then pulled away just before the gum carrier reaches its highest position. The eccentrics 40 are driven by the pulley 6, and the usual foot treadle mechanism 42' is adapted to move the clutch lever 43 for throwing the eccentrics into and out of action.

rllhe dished gumming plate and support 45 are preferably made to conform in shape and size, and are made in interchangeable pairs to adapt the 'machine for various forms, sizes or styles of shoes.

In operation, the work Vis fed to the machine by hand and placed upon the die, covering the opening 2 in the reservoir. The clutch is thrown into engagement byfoot power, and the movement of the eccentric withdraws the shutter from closed position.

The respective eccentrics cause the Vhammer or presser to descend, and the gum carrier .plate to ascend through the gummingv material. The dished plate carries a quan-` tity of material up under the work, and

the descending presser bears down upon the work which is now resting upon lthe gum carrier plate. The work or toe is thus gummed on the underside. The cushion 18 on the presser forces the toe down into the dished plate causing it to receive a' greater quantity of gum at its approximate center for purposes well known in the art.

The work I referred toas the box toe, it should be understood, is a piece of stiifening material, composed of either leather, cork, rubber, cloth, or felt, and forms one part of probably four or live thicknesses of material constituting the made up toe.

In actual practice one side of a piece of material as above set forth, may be gummed on one side, then by layingthis gummed piece upon another part, a lining material for instance, with the gummed surface in contact, the exterior face of the lining may be coated. The operation of gumming the exterior of the lining piece at the same time cements the gummed material to the lining` The operation may vbe repeated by laying on additional layers to the desired number, and the several layers, after being gummed or cemented together, make the completed box toe o-r upper.

IVe have not illustrated the gumming material in the reservoir, but it will be understood of course that a sufcient supply mayV be kept therein to the proper depth and replenished Y when necessary through the plugged opening 44.

From the above description taken in connection with the drawings it is evident that we have provided an efficient, and positively acting machine for accomplishing the purposes of a device of this character.

While wehave illustrated one complete form of the invention, it will be understood that'we may vary the machine within the scope of the following claims.

l/Vhat we claim and desire to secure by Letters Patent is l. The combination in a machine as described comprising a reservoir having an opening therein, of a carrier plate bodily movable through the reservoir to close said opening, a complementary open work supporting plate over the reservoir opening, and a presser member, with actuating means whereby the presser member and plate are brought into operative relation with the work support.

2.
