Application filed November 15, 1907, SerialNo. 402,285. Renewed February 6, 1912. Serial No. 675,909.

To all whom it may concern Be it known that I, Josnrrr H. Porn, a citizen of the United States, residin at Hamilton, in the county of Essex and mmonwealth of Massachusetts, have invented certain Improvements in Heel -'Attaching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to heel" attaching machines and more particularly to heel attaching machines having provision for securing top lifts to heels.

Heretofore top lifts have generally been formed of a unlform symmetrical contour whether they were to be attached to heels of right or left shoes. Then it has been desired that the top lift of an attached heel be of an unsymmetrical form, the necessary contour has been secured in the operation of breasting the heel. It will be seen that if such top lifts were originally formed of substantially the contour which is secured in breasting, some waste of leather occasioned in the latter operation would be avoided.

An object of the present invention is to provide a heel attaching machine with mechanism permitting the attachment to heels of top lifts of an unsymmetrical contour, such, for, example, as characterizes a right or a left heel.

It will be understood that the breast edge of a right or a left top lift is oblique to the longitudinal central line of the lift, the inclination for a right lift being opposite to that for a left lift. I

An important feature of the present invention accordingly consists in a top lift holder adapted to retain in a predetermined position a top lift having an oblique breast edge. e t

The embodiment of the invention herein shown comprises a rear-gage formed to engage opposite sides of the curved end of a lift, a breast gage held yieldingly toward the rear gage and arranged to engage the breast edge of the lift at a plurality of points, said breast age being so formed as to hold in op; erative engagement with the rear gage a top lift having an oblique breast edge- In order to effectively retain and position a top lift upon a holder of the nature above described, it is desirable that the breast gage engage a lift at its breast corners. breast gage herein illustrated is accordingly so formed that the portion engaged by one breast corner is arranged in advance of the other breast corner, or farther. toward the front of the holder. It is also desirable that the construction be such that the holder may accommodate top lifts of either of the con tours which characterize a right and a left lift respectively. The breast gage in the The holder shown is accordingly arranged for adjustment to permit a lift of either form to be retained thereon. 1.

A further feature of the invention relates to a provision for retaining securely a top lift or other heel blank upon a holder. In

machines now commonly employed inattaching heels a top lift holder is automatically moved into attaching position after a heel has been attached. In consequence of the rapid movement imparted to the holder and the shock incident to the arrest of its movement, lifts have been at times dislodged from the holder. To prevent such dislodgment the present invention contemplates roughening the portions of the gages which engage the edge of a lift. It is desirable that this feature shall not interfere with the action of the gages in positioning and centering the lift upon the holder. The gages are accordingly provided with parallel corrugations or ribs so arranged that they do not interfere with movement of the lift in its own plane. To this end the corrue gations or IlbS formed upon the gages extend in a direction parallel with the face of the lift.

Other features of the invention will be hereinafter described and defined in the claims. 7 t

In the drawings, Figure 1 is a view in plan with parts in horizontal section ofa portion of a heel nailing machine equipped with a top lift holder adapted to retain either right or left top lifts; Fig. 2 is a view in plan of a portion of the holder shown in Fig. 1, illustrating different positions ofthe parts; Fig. 3is a perspective view illustrating a rear gage provided with corrugations for retaining a top lift upon a holder; Fig.

4 isa perspective view of a breast gage plate 12 is arranged for movement about a pivot 14. The plate 12 is adapted to sustain upon its upper face a heel holder and a top lift holder. It will be understood that in the use of machines of this class the heel holder in the heel attaching operation is in line with the nail block. After the heel has been attached, the plate 12 is automatically actuated to move the heel holder to the left in Fig. 1 and bring a top lift carried by the top lift holder into alinement with the attached heel.

The top lift holder comprises a guide 16 which forms, in conjunction with the plate 12, two parallel guideways. The stem of a rear gage 18 is arranged in one guideway, and that of a breast gage 20 is inserted in theother guideway. The forked rear gage 18is stationary and controls the position of a top lift by engagement with opposite sides of its curved end. Adjustment of the rear gage, such as may be occasioned by a change in size of top lifts, is secured by a screw 22. It will be understood that the plate 12 is extended beneath the reargage 18 and the breast gage 20 and thus constitutes a spanker plate for supporting the top lift as it is spanked upon the heel. A spring 24 is arranged to hold the breast gage yieldingly toward the rear gage, the backward movement of said breast gage being limited by an adjustable stop 26.

The features of the machine thus far referrcd to by reference character are wellkno-wn in the art. A feature of the present invention consists in the provision of a bar 30 arranged upon the breast gage in, position to be engaged by the top lift at both the breast corners. One end of the bar 30 is pivotally connected to the breast gage at 32. The opposite end of the bar is main tained in stationary position by a pin 84, inserted in the bar 30 and cooperating with suitably arranged holes 36 in the breast gage to retain said bar in either of two positions in which the face of the bar is oblique to the longitudinal central line of the holder, asshown in Fig. 1. As will appear from Fig. 2, the obliquity of the face of the bar in one of these positions is opposite to that in the other.

I have illustrated'in Figs. 3 and 4, respectively, a. rear gage 40 and a breast gage 42 formed to prevent a top lift from being dislodged from its holder. As will appear from said figures the portions of said gages, with which the top lift comes incontact, are provided with parallel ribs or corrugations eX- tending in a horizontal direction.

In the use of the mechanism illustrated in Figs. 1. and 2, the bar 30 is adjusted according to the form of top lift to be attached. It will be understood that if a top lift of the contour shown at the left in Fig. 5 is to be attached, the free end of the bar 30 will be nxed in the position shown in full lines in Fig. 2, whereas if the top lift to be attached is of the Iorm shown at the right in Fig. 5 the bar 30 will be given the position shown in dotted lines in Fig. 2. The top lift is inserted by moving the breast gage forwardly to permit a lift to be placed between said gage and the rear gage, and the breast gage is then allowed to be moved rearwardly by the spring 24. In the rearward movement of the breast gage, the oblique breast edge of the top lift is engaged at the breast corners and the lift is pressed against the rear gage and also centered and properly positioned upon the holder. It will be seen from Fig. 1 that when a lift is in position upon the holder its longitudinal median line is in vertical alinement with the longitudinal median line of the holder. The top lift is thus located upon the heel with its rear portion in a symmetrical relation to the shoe.

The corrugations formed upon the gage sections, shown in Figs. 3 and 4t, effectively retain a lift upon a holder. A provision of this nature is particularly desirable where compressed top lifts are used, since the edges of such lifts are smooth and somewhat polished and are consequently not firmly gripped by gages having smooth faces. The arrangement of the corrugations horizontally permits movement of a lift in a horizontal plane upon the holder, such for eX- ample as would be occasioned by the positioning and centering action of the gage. It will be seen that the corrugations offer no obstruction to movement of a lift in a horizontal direction, or in the plane of the lift, although they resist movement of the lift in a vertical direction or perpendicular to said plane.

It will be understood that the top lift holder shown for accommodating top lifts of different contours is merely illustrative of one form ofthe invention. Variations in the holder shown may be made without departing from the present invention. It will also be understood that the provision for retaining securely a top lift upon its holder is of general application, and is not restricted' to use with a holder of the type herein illustrated.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A holder for heel lifts, having in combination, a rear gage for engaging the rounded end of a lift and a breast gage formed to engage the breast of the lift at a plurality of points having provision for simultaneously varying the positions of said points for the purpose of accommodating lifts with breasts of different or reverse obliquity.
