SPECIFICATION arming part of Letters Patent No. 588,978, date A Application ned December 19,1896. serai No. 616,302. (No man.)

T0 all whom, itmay concern: Y 'Be it known that I, WILLIAM GORDON, of Boston, inl the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Indenting Bootor yShoe Soles, of which the following is a specification. l, 1

' This invention has Aforgits. object toprovide a machine adapted to form a series' of grooves or indentations in a boot or shoe sole for the purpose of corrugating its tread-surface and thus adapting it to resist slipping, or for the purpose of increasing Athe rlexibilityrof the sole, my invention having inrview the formation of grooves or indentations without the removal of any of the material of the sole.

My invention consists in the improvements which I will now proceed to describe and claim.

In the accompanying drawings, Figure l represents a top plan view of amachine embodying my invention. Fig. 2 represents a front elevation of the same. Fig. 3 represents a section on line 3 3 of Fig. 2. Fig. 4 represents a section on line 4 4 of Fig. l. Fig.

g 5 represents a section on line 5 5 of Fig. l.

Fig. 6 represents a section on line 6 6 of Fig.

l 1. -Fig '7 represents a view similar to Fig. 6,

showing the grooving or indenting diein a different position. Fig. 8 represents a plan View of the grooving-die, detached. Fig. 9 represents a section on line 9 9, Fig. kS. Fig.

10 represents a view of a sole grooved or indented by myimproved machine. Fig. ll represents a section on line 1l 1l, Fig. 10. Fig. 12 represents a perspective view of a portion of the machine.

In the drawings, in which the same letters or igures designate the same parts or features,

a represents the supporting-frame of the ma--` chine, the same having a horizontal bed or table portion a. Y i

b represents a shaft which is vjournaled in bearings Von the 4frame a and having enlargements o,constitutin g bed-rolls or bed-roll sections arranged to support asole c, that passes from the'inner end of the bed or table a', the upper surface of said sections o being substantially iiush with the upper surface of the bed a.

ugust 31, 1897.

d represents a shaft or holder which is journaled in bearings in the frame a above the shaft b, and is provided with a fiat seat or face d', to which is detachably secured, by bolts or screws e', a grooving-die e', the back or inner surfaceof which is fiat and is formed to fit the seat d', while its outer face is convex and provided with ribs 2 2, formed to make grooves or indentations 3V 3, Figs. 10 and 11in one side of the sole c, which is passed between the die c and the bedroll b.

The die eis provided with iianges 'e2 e2, having slots c3 c3, which receive the attachingscrews e', said slots and screws permitting theV die to be adj usted longitudinally. The shafts b and d are positively rotated-by suitable gearing, which may be arranged as shown in the drawings or in any other suitable way, to rotate the said shafts and their attachmentsin the direction indicated by the arrows in Figs. 3 and 4.

A slide or carrier is provided to grasp the sole c and presenty it att-he proper time to the die e and the cooperating bed-roll section b to cause the dies to indent the sole, as indicated in FigQlO. The said slide or carrier, as here shown, comprises a frame composed of two side bars, each made up of two members g g', Fig. 12, a front cross-bar g2, connecting said side bars g g atthe front of the machine, and a rear cross-bar (3, connecting said side bars at-the rear of the machine. i

The members g of the side bars are fitted to slide in guides g4 in the bed or table a', and are provided with upwardly-projecting lugs gG, which are engaged by camsh, affixed to the shaft d, said cams by theirengagement with the lugs g( causing the feed frame or carrier tovmove forward in the direction indicated by the arrow in Fig. l2. To the feed slide or carrier are connected two pairs of jaws i t', adapted to hold'the end portion of a sole, as indicated in Fig. l, said jaws being yieldingly connected with the feed slide or carrier by means of 'a rod i2, which slidesl lengthwise in guides 6, adj ustably mounted on the front cross-bar g2, and springs't, interposed between the guides 116 and shoulders on the rod 2, said springs enabling the jaws t' t" to yield toward the front cross-bar g2.

The rods [2 are provided with right and left hand screwethreads i* and i5, which are engaged with correspondingly-th read ed orifices in the jaws i" and t', so that when the rods t2 are turned they adjust the jaws t' i' simultaneously toward and from each other, thus adapting them to soles of different widths.

The guides t" are adjustable toward and from cach other on the cross-bar g2, and are held at any desired adjustment by means of set-screws 7, so that the jaws can be adapted to any length of sole.

The feed slide or carrier is movable on the frame of the machine in a direction at right angles to the axes of the shafts l) and d, and is guided by fixed ears or guides jj, in which the members g of the side bars are fitted to slide. The said feed-slide is moved in the direction required to carry a sole engaged with the jaws t' t" toward the meeting point of the indenting-die and corresponding bedroll by means of the cams 71., the latter engaging the ears g on the feed-slide, as shown in Fig. 4. Vhen the cams pass over the ears gs, the feed-slide is released and is returned to its starting position by means of a spring 7n, attached at one end to the frame of the machine and at the other end to an arm 7c', affixed to the rear cross-bar g3.

m onr represent stops which limit the movement of the feed slide by means of the sprin g 7c.

The operation is as follows: After the feedslide has been returned by the spring 7o to its starting position and before the cams 7L reach the lugs gf the operator engages a sole with the jaws i li'. lVhcn the cams engage the lugs g, the feed-slide is moved forward, carrying the sole with it and presenting the sole to the die e and the accompanying bed-roll just as the die reaches the position to engage the advancing edge of the sole at a point within its margin. The cams continue to advance the feed-slide and sole while the die is acting upon it, the result being the formation of the grooves 3 3 in the sole, as shown in Figs. l0 and ll. After the die has completed its action the cams release the lugs g6 and the feedslide is returned to its starting position, which is determined by the stops m.

In opcratin g upon the soles which are formed as rights7 and lefts the die for one form will be placed at one end of the seat d', while for the other form the die will be placed at the opposite en d of said seat, which, as shown in Fig. l, is made of suflicient length to re ceive two dies, the screw-holes d10 d10 (shown at the left-hand end of the seat in Fig. l) indicating where the other die would be attached to the holder.

10 1110 represent ears or plates which are attachcd to the jaws t" to prevent the jaws from dropping onto the shaft b when they are moved over the latter, said plates @'10 trailing after the jaws and remaining on the table a.

The jaws 'i are at the same time supported by rods i12, attached to the jaws t" and having a sliding itin holes formed in the jaws if.
