Application filed June 27, 1907. Serial No. 381,130.

the following is a specification, reference being had therein to the accompanying drawm g.

The present invention relates to' machines for forming stitch imitation impressions or indentations 1n the pro ecting edges of shoe soles and particularly to that class of sole indenting machines in which the indent ing tool consists of a wheel provided with teeth shaped and spaced to produce the desired form of indentation. Certain features of the invention are, however, not limited to use in conneotion with a sole chine provided with an indenting wheel but may be embodied in other types of sole indenting machines.

One of the objects of the present invention is to produce a sole indenting machine provided with an indenting wheel mounted to be rotated by the engagement of the work therewith in which the wheel is so actuated as to assist in the feeding of the work. With this object in view a feature of the invention contei'nplates the. provision in a machine of the character referred to of means for shifting the wheel bodily in the general direction of the feeding movementof the work and position of the wheel with relation to the work support.

Another object of the present invention is to provide an improved means for actuating the tool of a sole indenting machine which is simple in construction and eflicient and durable in operation. in view a feature of the resent invention consists in the improved too l actuating mechanism hereinafter described and claimed which mechanism is particularly applicable to a sole indenting machine provided with an indenting wheel but which except as de fined in the claims, is not limited to use in any particular type of sole indenting machine.

Other objects of the invention are in general to in'iprovc the construction and mode of inafter described and indenting malugs wherein like re "nate correspondlng parts in the several to be shown herein,

with this object operation of solo indenting machines and with those objects in view the present in vention also consists in certain devices, combinations, and arrangements of parts hereclaimed, the advantages of which will be obvious to those skilled in the art from the following descriptionz- H The several features of the present invention will be clearly understood from an inspection of the accoinpanyint drawings in which is illustrated a sole in entin machine embodying the form. 1

In the drawings, Figure 1 is a side elevation of the machine, a portion of the casing being'show-n in vertical section; Fig. 2 is a plan View of Fig. 1 withv the casing shown in horizontal section; Fig. 3 is a detail view of the operating shaft removed; Fig. 4 is a front view; Fig. 5 is a plan view of the table support and associated parts with the table removed; Fig. 6 is a section on the line y-y of Fig. 2; Fig. 7 is a section on the line m-a2 of Fig. 2; and Fig. 8 is a detail same in their pre erred perspective view of the separable bearing box, or brasses, for'the angularly dispose crank of the operating shaft.

Referring more s ecifically to the drawfierence characters desigrepresent a pair of supporting to or forming a part of or column, not necessary at alined points in the upper ends of which are bearings B for a horizontally disposed operating shaft C having at one end a pulley D and at its opposite end a removable collar E for securing the shaft in place. Pivoted to rock upon the shaft C is a casing F open at its bottom for the reception of the upper ends of the uprights A and to permit the adjustment of the casing over said uprights. The casing has a forwardly extending cylindrical portion G to constitute abearmg for an oscillating shaft, as will presently appear, and beneath this cylindrical portion I provide an ad justa'ble rest H adapted'to adjust the casing with the parts carried thereby to any position desired and to support the same in such views, A-A uprights attached the ordinary frame I position.

frusto-conical formation rotatably and removably mounted in a casing J, said casing J being in turn pivoted as at Kto a shaft L operated by a pulley M belted to .or otherwise .operatively associated with the pulley D. Either of these pulleys D or M may be driven from any suitable source of power. The shaft L is rotatably mounted in cars N on a bracket 0 removably and adjustably secured to the uprights A as at P.

Q is an adjusting screw passing through th bracket 0 and bearing on the bottom of the casing J to adjust the table to difierent positions on the shaft L;

Within the casing J and rigidly secured to the table or support I 15 a worm wheel R meshing'with a worm S secured to the shaft L whereby the rotation of the shaft, worm and wheel will effect the desired rotation and feeding movement of the table or work support.

Above the work support is an indenting wheel T which is carried. by but offset from a shaft U whereby the turning of the shaft by instrumentalities now to be pointed out will effect an oscillation of the wheel carrying arm V. The wheel is free to rotate relative to said arm V. The shaft U passes through the cylindrical portion G of the cas ing F and is removably held therein by the detachable coupling WV threaded thereinto, the latter constituting one bearing for the shaft U and an enlarged cylindrical portion X at the inner end thereof and fitting the bore of the cylindrical portion G constituting another bearing for said shaft, wherebyto properly center the shaft and preserve the same against vibration.

The enlargement X at the inner end of the shaft I just referred to is slotted inwardly from the end thereof for the reception of an angularly disposed crank Y formed on the shaft C intermediate the ends thereof (see Fig. 3), a separable bearing box, or brasses, Z being interposed between said crank and the parallel flat surfaces of the slotted portion of the shaft U, the opposin surfaces of these brasses being correspon ingly fiat, and the thickness of the bearing box, or brasses, when assembled being such as to snugly fit said slotted portion. The special formation of these brasses will be clear' upon an inspection of Fig. 8. "Owing to the cooperative relation of the angularly disposed crank Y ofthe operating shaft with the slotted end of the tool shaft I and the offsetting of the freely rotatable tool T from the shaft U, the rotation of the operating shaft will effecta back-and forth rocking movement of the shaft- U and bodily oscillation of the wheel '1 as indicated by the are represented in Fig. 4, the extent of movement of the wheel being approximately twenty degrees, and said are terminatingin substantially the lowest position of the wheel relative to thework support I or the work therebetween. wheel will effect the desired impression or indentation in the work and inasmuch as its movement to its lowermost position is in the direction of feeding of the work beneath the wheel, the wheel will materially assist in such feeding. operation. On the other hand, the rearward movement of the wheel being in an arc receding. from the work the feeding of the work under the actuation of the work support I will not be materially 1mpeded thereby.

It is to be observed that while in the hereto appended claims I will define the tool carrying shaft as having a slotted portion, such term is to be understood as embracing any equivalent of such formation, as for instance two oppositely disposed arms connected to the shaft and having a space therebetween to accommodate the angular-1y disposed crank.
