WORK-POSITIONIN G DEVICE.

Application filed August 14, 1926. Serial No. 129,203.

This invention relates to work-positioning devices for the soles of boots and shoes and 1s illustrated as embodied in a stamping machine to assist an operator in presenting a sole thereto so that a mark may be stamped upon the surface of the sole.

Manufacturers frequently desire to impress some mark on the exposed or grain surfaces of unattached insoles in a position where it may be seen after they have been embodied in the completed shoes. Frequently this mark takes the form of a trade-mark of a substantial size, and it is particularly essential that such a mark becorrectly located with respect to the insole so that it will occupy the desired position in the finished shoe and be completely exposed to the view of a salesman or a customer.

Accordingly, an object of the invention is to provide an improved device by means of which the operator will be enabled rapidly and accurately to locate insoles for the operation of a machine such as a stamping machine so that the applied mark will occupy the desired position upon the insole. In the construction illustrated in the drawing, in accordance with features of the invention, a slidable, V-shaped gage is provided in which the heel end of the insole may be placed, and this gage is resiliently held in forward position. Co-operating with the heel-locating I gage is a pointer by means of which reference may be made to some fixed feature of the insole such as a mark indicating the heel-breast line. Both the heel gage and the pointer are attached to the stamping machine and the pointer is in a fixed relation to the'anvil of said machine. The operator places an insole against the V-shaped, slidable gage, which will automatically center the end of the insole and then will move the insole, sliding the gage, until the desiredmark upon the insole registers with the pointer. By utilizing this chine provided with my improved positioning device;

Fig. 2 is a plan View of the anvil of the machine and the work-positioning device, show ing an insole located in position to be stamped; and

Fig. 3 is a perspective of the anvil and Work-positioning device.

For the sake of illustration, the novel Workpositioning device of the drawings has been shown as embodied in a stamping machine of the type illustrated in Letters Patent of the United States No. 1,028,567, granted June 4, 1912, uponthe application of W. Gordon and L. E. Topham. Such a machine embodies a standard 10 having an overhanging head 12 in which is slidably mounted a plunger 14 carrying a turret 16 in which there is supsupporting surface member 26 retained upon the anvil by suitable clamps 28. This supporting member 26 may be of any suitable material such as fibre, leather or the like, and preferably is sh ghtly resilient but is suiiicient- 1y firm to allow the machine to make the desired impression upon the work.

Bolted to the anvil 24 at its rear end is a bracket 30, which serves as a support and a guide for a sliding carriage 32 to which there is secured by means of screws a V shaped gage member 34 having a superposed cross-bar 36. A removable stop 38 such as a cotter pin is provided in the outer end of the bracket 30 to limit the movement of the sliding carriage 82, and a spring 40 (Fig. 1) is secured to the carriage 32 and to a dependlng post on the bracket 30 and is arranged resiliently to hold the work-positioning device in forward position. This spring is purposely made li 'ht so that an operator may place the heel cut of each insole within the recess formed by the V-shaped gage member 34 and beneath the superposed cross-bar 36 and readily push the insole and the gage rearwardly against the tension of the spring 4O until some suitable mark, such as the breast line 42 upon the insole, registers with the .end of an overhanging pointer 44 held relatively fixed by screws 46 upon the side of the anvil. The act of inserting the heel end of the insole in the V-shaped gage member serves to centralize one end, here the heel end, of the insole with respect to the work-positioning device and consequently the anvil of the machine, and the operator is enabled to bring the insole into the desired marking position quickly and accurately and with substantially no care or exertion. Since the operator must insert each piece of work beneath the.

cross bar 36 in order to bring it into engagement with the centering gage member 34, he will be assured that the work is substantially at the level of the work support. When the stamping die 18 engages that piece of work it will be centered in the machine, and, in addition, there will be no tendency to a blurring action of the die as might bethe case if the work were held up in the air and pushed down by the die. When the insole and the gage member have been moved back until the breast line 42 registers with the pointer 44, the shank portion of the insole is in position above the anvil 24 ready for the operation of the stamping machine. Thus the work-positioning device enables the operator to stamp a large quantity of insoles in a minimum of time and to be assured of the correct f location of the stamp upon each of the insuch as unattached outsoles.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent of the United States is:

1 In a machine for operating upon boot and shoe parts, a work-positioning device comprising a work support, a slidable end gage associated with said work support and resiliently held in forward position, and relatively fixed indicating means associated with the work support and constructed and arranged to cooperatewith another portion of a piece of work to enable the operator to move each piece of the work against the tension of the gage to bring that piece of work to desired position over the work support.

2. In a machine for operating upon boot and shoe parts, a work-positioning device comprising a work support, a bracket on said position above the work support.

3. In a machine for operating upon boot and shoe parts, a work-positioning device for insoles or the like comprising a flat work support, a V-shaped back gage slidably mounted upon said work support and resiliently held in forward position, and a pointer held in fixed position with respect to saidwork support and adapted to be registered with a fixed point on the insole so that the end of an insole maybe placed in and centralized by said V- shaped back gage and the insole moved over the work support until it occupies the desired relation to said pointer and henceto the work support.

4. In a machine for operating upon boot and shoe parts, a work-positioning device comprising a J-shaped back gage having a superposed cross-bar whereby the end of a shoe part may be inserted in and centralized by said V-shaped back gage and held at the level of the back gage by the cross-bar. V

5. In a machine for operating upon boot and shoe parts, a work-positioning device for insoles or the like comprising a work support, a bracket secured to said work support, a V shaped back gage slidably mounted upon said bracket, a spring arranged to hold said gage in forward position, said V-shaped back gage being provided with a superposed cross-bar arranged to hold the end of aninsole at the level of the backgage so that it may be centralized thereby, anda pointer upon the work support adapted to be registered with the heel-breast line of the insole as the insole moves the back gage against the tension of the spring thereby to posit-ion the insole in correct relationto the work support.

6. In a machine for operating upon boot and shoe parts, a tool for operating on the work, awork support,and a work positioning device thereon comprising a gage constructed and arranged to center each piece of work with respect to said tool and constructed and arranged to assist in maintaining a piece of work substantially at the level of the work support. V p v f In testimony whereof I have signed my name to this specification. I
