SOLE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 616,917, dated January 3, 1899.

Application filed 511119 16, 1898- To all whom it may concern.-

Be it known that I, CAREY E. GODDARD, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented a new and use-' an improvement on what is known as the WVellman sole-cutting machine. In this style of machine the leader is relatively stationarythat is to say, it has no horizontal movement, inasmuch as it is rigidly connected with the holderand by means of the ordinary yielding knife-block a single leader may be employed in cutting three sizes of rubber soles, one of which is above and one below the size for which the leader is particularly adapted.

Itis the object of myimprovement to enable the machine to cut a greater number of sizes say twelve-'-using a single leader. In other words, twelve cutting-forms, one for each of twelve sizes, may be applied to a machine with a single leader.

In carrying out my invention the leader is reciprocated horizontally and longitudinally under the holder during the process of cutting the sole by means of a double eccentric or a pair of eccentric-rings placed one outside of the other and capable of adjustment with relation to each other, the extent of its movement being regulated by the eccentrics and depending on the length or size of the sole to be cut.

The nature of this invention is fully described in detail below, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a sufficient portion of a WVellman sole-cutting machine to illustrate my improvement, which is embodied therein. Fig. 2 is an enlarged section taken on line 2, Fig. 1, showing the leader in plan View, with the knife or cutter at the heel end, as in Fig. 1. Fig. 3 is an enlarged vertical section taken on line 3, Fig. 2. Fig. 4 is a section and plan similar to that shown in Fig. 2 with the knife at the toe end. Fig. 5 is a Serial No. 683,564. (No model.)

diagram of the leader, the full lines showing the position of the eccentrics fora middle size and broken lines showing the positions when the eccentrics are set as in Figs. 6 and 7. Figs. 6 and 7 are diagrams showing the eccentrics set for the highest and lowest sizes, respectively, the cutter being at the toe.

Similar letters of reference indicate corresponding parts. i

a represents the cutting-form, secured to the cutting-form holder 1), which is supported by the post d, whose elongated top d connects with the under side of' the holder A by means of screws e. (See Fig. 3.) B is the leader, provided with the usual flange B. All these parts are constructed substantially as usual, with the exception that the leader B is provided with a longitudinal slot 0, through which the screws 6 extend, which connect the holder A upon the leader with the portion cl of the post or connection 01. Ordinarily the leader, post d, and holder Aare rigidly connected; but in this improvement by means of the slot C the leader is alloweda horizontal movement, and can thus slide longitudinally with relation to the holder A and cutting-form a.

D represents a portion of the frame of the machine, within which the vertical spindle D" is held adj ustably as to height, said spindle being provided with the foot-guide D", which looks into the holder A, and said spindle being adapted to be pressed down by a treadle through the means of a system of levers f and being guided by a tube or sleeve 9, all as common in machines of this description. Swinging horizontally on this tube 9, by means of the hub h, is the jointed arm h, in the outer end of which is the vertical shaft or spindle is, which supports a carrier Z, to which is pivotally secured the knife-block n, supporting the knife or cutter S, all as usual. As this knife-block mechanism is carried around the leader by means of the ordinary actuating r, the guide-rolls t traveling along the inner surface of the flange B of the leader, thus holding the knife-block to its work and cutting out the sole Y, all in the ordinary manner and requiring no detailed explanation.

E E are structures mounted on the leader and each provided with two legs E, secured at F to the leader 011 opposite sides of the holder A, and each formed with an inwardly extending horizontal lip E. Rigid 011 the hub h of the jointed arm h is a horizontal disk or circular plate ll, provided with the two curved slots 11 and H, Figs. 2, 3, and 4. Normally loose on the hub 7i below the disk II is an eccentric ring or cam K, whose position on said hub and with relation to the disk is determined by the thumb'screw P, extending into it through the slot 11 and setting against the upper surface of the disk. Normally loose on the periphery of the eccentric ring or cam K is an eccentric ring or cam L, whose relative position is regulated by the thumb-screw P, extending into it through the slot 11 and setting against the upper surface of the disk.

By reference to Figs. 1 and 8 of the drawin gs it will be seen that the disk H, which is of greater diameter than the outer eccentric, rests on the lips E", while the eccentrics lie between the lips and with the periphery of the outer one against both said lips. As the knife S is guided around the cutting-form a by the guide-rolls 15, which run along the inner surface of the flange B of the leader B, the periphery of the outer eccentric-ring L is in constant contact with the lips E". Now if the eccentrics are in the position indicated in Fig. 5 their thick sides are opposite each other, with the effect that the spindle D is exactly in the center of the circle described by the periphery of the eccentric-ring L. Hence the eccentrics neutralize each other and the leader is stationary. This would be the position when a middle size, such as N 0. 6, were to be cut. The only latitude in such a case would be that one size larger or smaller could be out while using the same leader by reason of the spring 1', which affects the knife, and this is the case with the \Vellman solecutting machine as heretofore constructed; but should the eccentrics be set in the relative position indicated in Fig. 6,with the knife S and rolls tat the toe end of the leader-that is to say, with the thick portions of both eccentrics toward theknifetheleader would be moved by the action of the double eccentric longitudinally outward toward the toe of the cutting-form, (being allowed such movement by the slot 0,) and as the knife was carried to and around the heel end the leader would be moved longitudinally in that direction, inasmuch as the eccentrics rotate with the hub of the jointed arm. Thus with the eccentrics in this position the leader would reciprocate longitudinally as the knife moved around the cutting-form, so that the largest-sized sole, such as No. 12, could be cut. On the other hand, should the eccentrics be in the position indicated in Fig. 7, with the knife at the toe end-that is, with their thick sides inward or from the knife-the leader would slide inward or recede as the knife passed the toe and heel, reciprocating in the opposite directions from those before described, so that the smallestsized sole, such a No. 1, could be cut. Should the eccentrics be placed in any position intermediate of that shown in Fig. 5 and those shown in Figs. (3 and 7, the reciprocation of the leader would be governed thereby and intermediate sizes of soles produced. Thus it will be seen that but one leader is necessary in cutting around twelve different cuttingforms and producing twelve sizes of soles, inasmuch as by loosening the screws P P the eccentrics can be adjusted so as to produce any length of throw permitted by the slot 0. Practically, however, three or four adj ustments are sufficient, inasmuch as the knife mechanism will adjust itself to a size above and one below any particular size to which the eccentrics may be set.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a sole-cutting machine of the character described, the combination with the cutting-form holder, knife-block mechanism and means for actuating the latter; of a leader connected non-rigidly with the cutting-form holder, and mechanism intermediate of said leader and knife-block mechanism and actuated by the latter whereby the leader is reciprocated horizontally as the knife passes around the cutting-form, thereby adapting the leader to the size of the form secured to the cutting-form holder, substantially as described.
