7 Claims.

This invention relates to fastening-inserting machines and is hereinillustrated in connection with a device for supporting and guiding a shoe in operative position relatively to fastening-inserting mechanism.

In some types of shoes one or more rows of fastenings are driven through the outsole and into the insole at the shank portion of the shoe in order to reinforce said shank portion for the purpose of stiffening it and for preventing ripping of the threads caused by relative sliding movement between the outsole and insole. Such rows of fastenings are also sometimes driven into the shoe to provide ornamentation.

It is an object of the invention to provide an improved shoe support and gage by which a shoe can be readily advanced past fastening-inserting mechanism to receive one or more rows of such fastenings evenly spaced from the edgesvof the go outsole.

To this end and as illustrated, I have provided, in a machine of the type referred to, a support adapted to enter the welt crease or shank crease of a shoe and a gage mounted upon the support for engaging the edge of the sole of the shoe to position the same in operative relation to a fasv tening-inserting tool, the support and gage preferably being adjustable laterally relatively to each other and to the tool so that the spacing of a ro'w or rows of fastenings driven into the sole of the shoe can be readily varied.

These and other features of the invention are disclosed in the following specification and in the accompanying drawing and are pointed out in the appended claims. y

In the drawing Fig. 1 is a view in side elevation and partly in section of a portion of a fastening-inserting machine embodying one form of my invention;

,m Fig. 2 is a detail view in side elevationof the shoe support and gage;

Fig. 3 is a top plan view of the shoe support and gage; and

Fig. 4 is a detail view partly in section showing the manner in which the gage and support engage the shoe.

Fig. 1 illustrates a portion of a machine for driving fastenings such as wooden pegs or nails in shoes. 'Ihis machine comprises a frame l0 having a spindle l2 which carries a horn I4 arranged to be moved heightwise of the machine in presenting a shoe I6 with the sole I1 thereof in engagement with the horn to fastening-inserting mechanism including a presser plate I8 and a tool diagrammatically indicated by reference character 2li. The fastening-inserting'-y mechanism which is not herein illustrated in detail may be of any suitable construction such as that shown and described in United States Letters Patent No. 581,066, granted April 20, 1897, 5 upon an application led in the names of J. F. Davey and S. W. Ladd. v

In order to support a shoe to be operated upon against the thrust of the fastening-inserting tool vI have provided a supporting member in the l0 form of a plate 22 slidably mounted in a groove*Y 24 in the upper end of the horn I4. This support has a wedge-shaped nose portion 26 which is adapted to enter the shank crease or the welt crease of a shoe to be operated upon to engage `l1 5 the under side of the sole or the Welt to support f "i the shoe. The supporting member or plate 22 is movable laterally of the tool 2U for purposes of adjustment and can be locked in adjusted position by means of a capstan screw 28 extending ,p20 through an elongated slot 3D in the plate 22 andi'f-l' into the body portion of the horn, the screw being readily operated by means of a pin or handle 32.

I have provided a gage 34' for contacting' withvfez' the edge portion of the sole of a shoe in position f" upon the supporting member 22 for locating the shoe with the edge of the sole in predetermined position laterally of the tool 20. This gage 34 is in the form of a plate slidably mounted upon to the supporting member 22 and arranged to be f secured in fixed relation thereto by a bolt 36 which extends through an elongated slot 38 in the gage and into the supporting member. The screw 28 also passes through the slot 38 and the head of the screw engages the upper surface of Vthe gage 34 in securing the plate 22 and the gage 34 in adjusted position. The gage 34 is normally moved with the supporting member 22 and it can be located with the member in various positions 40 laterally of the tool 20, thus to provide for means for spacing from the edge of the sole of the shoe a row or rows of fastenings to be driven in the sole of the shoe.

Since it is sometimes desirable to drive two 4r, spaced rows of fastenings into a shoe, for example along the shank portion thereof, I have provided means for readily locating the gage 34 in either of two predetermined positions. To this end the supporting member 22 is provided with a 50 downwardly projecting portion 40 which carries a screw 42 which acts as a stop to engage a at portion 44 on the horn to limit outward movement of the supporting member andgage. The position of this stop screw 42 can be vadjusted VC5 and the screw can be locked in adjusted position by the nut 46. To limit inward movement of the supporting member and gage there is a stop screw 48 extending through the depending portion 4U and into the horn. The screw 48 has a head 50 which is adapted to engage the depending portion 40 when the supporting member 22 is moved to the left in Fig. 2. The position of the head can be adjusted by rotating the screw 48 which can be locked in adjusted position by a nut 52. Thus it will be seen that by releasing the locking screw 28 the supporting member 22 and gage 24 can be adjusted in either direction between two limiting positions determined by the positions of the

screws

42 and 48. By this mechanism the gage 34 can be positioned to locate a shoe relative to tool 20 for spacing the fastenings to be driven at any desired distance from the edge of the sole of the shoe and can rapidly be shifted to either of two predetermined positions.

The horn I4 is supported in a bracket 54 secured Vto the upper end of the spindle I2 and is arranged for movement heightwise of the machine in locating a shoe against the presser plate I8 adjacent to the tool 28. The spindle I2 is normally held in elevated position by a system of links 56, there being a treadle 58 secured by links 60 to the lower end of the spindle I2 for depressing the spindle to permit insertion or removal of a shoe between the supporting member 22 and the presser plate I8.

In driving the fastenings into the shoe it is desirable that the latter be held with its sole lying in a plane substantially at right angles to the line of action of the tool 20. To assist the operator in accomplishing this, I have provided an auxiliary supporting member comprising a roll 62 carried at the upper end of an arm 64 pivotally mounted at 65 upon the bracket 54. The roll is adapted to enter the welt crease or shank crease of the shoe at a point upon the opposite side of a shoe from that engaged by the supporting member and cooperates with the latter to maintain the shoe with its bottom substantially normal to the line of action of the tool I8. The roll 62 is carried by a shank 66 which is adjustable heightwise of the arms 64, the shank being held in adjusted position by two bolts 68 which extend through an elongated slot 'I0 in the arm 64 and into the shank 66.

The arm 64 is normally forced about its pivot 65 in a counterclockwis-e direction (Fig. 1) thereby to urge the roll 62 toward the support 22. This is accomplished by spring 'I2 which extends between an ear 'I4 on the bracket 54 and an ear 'I6 on the arm 64.

In the operation of the machine the treadle 58 is depressed and a shoe such as shoe I6 is positioned upon the supporting member 22 with the nose 26 thereof extending into the shank crease or welt crease of the shoe and with the edge of the sole in engagement with the gage 34 and the roll 62 in engagement with the opposite side of the shoe. The treadle is released with the result that the horn is elevated to present the shoe to the presser plate I8 and the shoe is advanced past the fastening-inserting tool 28 which drives a row of fastenings through the outsole and into the insole along one side of the shoe. The shoe is then reversed and the same operation performed upon the other side of the shoe. If it is desired to drive a second row of fastenings the supporting member 22 and gage 34 are moved to the right or left as the case may be and the operation repeated.
