Fi l e d S e p t l 8 l 9 33 Patented Dec. 3, 1935 UNITED STATES PATENT OFFICE GAUGE Application September 18, 1933, Serial No. 689,817 In Great Britain October 5, 1932 4 Claims.

This invention relates to gauges and is herein illustrated as embodied in a gauge for locating soles relatively to the bottoms of shoes to which they are to be attached. According to theprocedure normally followed in manufacturing shoes of the McKay type, a shoe after being lasted and having various other operations such as pounding up, bottom filling and shank attachment performed upon it is ready to have its outso-le secured thereto. The outsole has commonly been channelled and has been moulded to the shape of the shoe bottom prior to its reaching the shoe. Before the outsole is permanently secured to the shoe by sewing or by other fastening means the usual practice is to secure it in proper position to the shoe by temporary fastenings which serve to hold it in proper relation to the shoe while the sewing or other permanent fastening operation takes place. Several methods are employed for such temporary securing of the sole to the shoe. In some factories the sole is temporarily secured to the shoe by a small number of metallic fasteners inserted by a so-called wire grip tacking machine or by a staple fastening machine. In other factories the sole is temporarily secured to the shoe by adhesive (conveniently using a rubber latex composition) the sole and shoe being pressed together in a sole laying machine. Still other factories make use of metallic fasteners and in addition adhesive temporarily to secure the sole to the shoe. Regardless of what method is employed temporarily to secure the sole to the shoe it is highly important that the sole should be accurately located in proper position on the shoe bottom. Outsoles for McKay type shoes are commonly rounded, while in the loose state, to such .a shape that little margin for error is left in the placing of the sole on the shoe, that is, the loose sole is very little larger than the sole of the finished shoe after an edge trimming operation has been performed. In View of this and in view of the fact that heretofore it has been common practice for the operator to depend upon his eye alone in positioning such soles upon the bottom of shoes it frequently happens that shoes having defective soles are produced. In view of the foregoing it is an object of the invention to provide a novel gauge which will facilitate the positioning and accurate location of a sole relatively to the bottom of a shoe to which it is to be attached.

To this end and as shown, the invention provides a gauge in the form of a member having an upstanding portion for engaging the upper of a shoe and terminating in a step, and a second upstanding portion adjacent to the step which is adapted to engage the edge of a sole positioned on the step for locating the sole in predetermined position relatively to the bottom of the shoe. 5 Preferably, and as shown, the member referred to constitutes one of a pair of arms adapted to embrace the shoe, the arms being pivotally mounted for movement toward and away from each other to provide for the insertion of shoes and soles of 10 different sizes.

The construction above outlined is advantageous in that a sole can be readily located relatively to a shoe bottom by means of the gauge and can be presented to mechanism for attaching a sole to the shoe or to other mechanism with the sole in accurate alinement with the bottom of the shoe.

These and other features of the invention will be apparent from the following detailed description when taken in connection with the accompanying drawing and will be pointed out in the claims.

In the drawing,

Fig. 1 is a perspective view of a gauge embody- 25 ing the invention; and

Fig. 2 is a perspective view on an enlarged scale showing the mounting of the gauge arms.

As shown in the drawing the gauge comprises arms l0 and I2 extending substantially in the 30 form of a U-corresponding in curvature to the toe portion of a shoe. The arm I!)v has a shank portion l4 having a lug l6 positioned between ears N3 of a shank portion 20 of the arm l2, the arms being arranged for angular movement 35 relatively to each other upon a pin 22 which extends through the ears l8 and the lug l6 and forms part of a support 23 upon which the gauge is conveniently carried. The arms are normally forced toward each other by springs 24 located 40 in holes in the shank l4 and the ears I8. Inward movement of the arms is limited by a set-screw 26 in the lug 16 which has a head engaging one of the ears l8, thereby to form an adjustable stop by which the spread of gauge arms may be ad- 45 justed to different sizes of shoes to be inserted between them.

Each of the arms I0 and I2 comprises an upstanding wall having a curved portion 28 adapted to engage the side of the upper of a shoe 50 forced between the arms bottom up. The portion 28 terminates in a flange or step 30 against which the bottom of the shoe may be positioned and upon which a sole to be located relatively to the shoe bottom may be supported. Adjacent to 35I1being held in position by the spring 36.

the step is a second upstanding portion. 32 which is adapted to engage the edge of a sole when in position on the step. The portion 32 is displaced laterally of the portion 28 by a distance corresponding to the amount that the sole will project beyond the edge of the shoe bottom,

thus when a shoe and sole are in engagement with the surfaces of the portions 28 and 32, respectively, along the length of the arms l and I2, the periphery of the sole will be located longitudinally and transversely of the shoe bottom itself.

In order to assist in positioning and holding soles upon the step 36 there is provided a leaf spring 34 mounted upon the pin 22 and held in position by a nut 36. The spring has two arms 38 each of which is adapted to bear down upon a portion of the step iii! to hold a sole in position thereon, the ends of the arms being upturned slightly so that the sole can be inserted readily'between the arms 38 and the step 39. The spring 34 is preferably provided with two or more holes it so that the spring may be located on the pin 22 in any one of several positions longitudinally depending upon the size of shoes which are to be inserted in the gauge.

In the operation of the device the toe portion of a shoe is inserted in the gauge with the side portions of the upper thereof in engagement with goi' the portions 28 of the arms in and I2 with the bottom of the shoe in contact with the underside of the step 39. A sole is then placed on the upper side of the step 30 with its edge portions in contact with the portions 32 of the arms, the sole "Ihe periphery of the sole will then be located in proper position relatively to the edge of the shoe bottom and the shoe and sole while in position in the gauge may be moved bodily into oprelatively to the shoe to which it is to be at- 5 tached.

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

l. A gauge comprising a pair of arms each of 1 which has a shank portion and a curved shoe-enlgaging portion, means for mounting the arms for movement relatively to each other comprising a pin extending through the shank portions, resilient means engaging the shank portions for forcing the arms toward each other, and a stop for limiting inward movement of the arms.

2. A gauge comprising a pair of arms mounted for movement relatively to each other and having each a shoe upper-engaging portion and a sole-engaging portion, and resilient means carried by the gauge for holding a sole inv engage-. ment with the' sole-engaging portion.

3. A gauge comprising a pair of arms each of V which consists in a curved wall having an upstanding portion adapted to engagethe upper of a shoe, a step for supporting the sole of a shoe and a second upstanding portion adapted to engage the edge portion of a sole, and a spring for holding a sole in position upon the step.

4. A gauge comprising means extending in the form of a U for embracing a shoe and having walls for engaging the upper of a shoe and the edge of a sole to be attached to the shoe, a projection extending along said walls for engaging 35 the bottom of the shoe and a face of the sole, and means for maintaining the sole in engagement with the projection.
