This'invention relates to improvements in the attachment of top lifts to wood'heels and to improved wood heels. 7 f In attempting to attach -top lifts to wood heels by rows of slugs or other fastenings 1nserted through the top lifts parallel to and near the edges of the top lifts and heels dif ficulty hasYbeen experienced by reason of the tendency of theheels to split adjacent to their breast corners. The grain of the wood of wood heels runs lengthwise of the heels and when 'a row of fastenings is insertedparallel to the edge of the top lift 7 and spaced 0f an inch or so frornthe edge of the'top lift with the fasteningsg or of aninch apart the strain put upon.

the wood is often more than it can stand, particularly in the case of high heels having small top lifts. For this reason heretofore, in order to obviate the losses due to excessive splitting of heels, the more usual practice has been to rely upon fastenings inserted a considerable distance from the edge of the heel to hold the top lift in place, the slugs, if any there be, being driven into the top lift but not any substantial distance into the wood of the heel.

It is an object of the present invention to provide a method of attaching top lifts to wood heels whichrwill eliminate the danger of splitting the heel even though a row of closely spacedfastening be driven through v the top lift into the wood heel close to the edge of the top lift and heel. I have dis: covered that if holes for the reception of the fastenings are made with an awl having a V-shaped or chisel point positioned with the the heel adjacent to the breast corners of the heel is practically eliminated. In the case of wood heels having leather top lifts, more-' over, the passage of the chisel point of the awl through the leather top lift is effective to force the fibre of the leather of the top lift below the surface of the '-wood of the heel, depressions into which the fibre of the leather :isldfagged being formed at oPl?osite sides of the holes. This prevents the top lifts from working on the heel, and pro-V VIClQS- an unusually secure attachment for the toplift. v V I 1 In another aspect this invention comprises a wood heel having a leather top lift attached thereto by fastenings, for example paper pegs, inserted through thestop lift into the heelwith the fibre of theleather' adjacent to the fastenings forced downwardly below the surface of the Wood of the-heel, and thereby preventing the top lift from working'upon the heel and eventually becoming loose."

. The wood heel of Fig. 1 is vprovided with covering .12 of any suitable material, for exampleleather or celluloid, and a top lift :14 illustrated as of leather. In attaching the top lift to the heel in accordance with my invention, the heel with the top lift held in position, for example manually, may be placed the-usual. wooden bodyinember 10having a upon the work-support .16 ofafastening inwhine (which, ,as illustrated,,is of the well- W v 65 WVit-h the'ab'ove and other objects in view 1 sertinga-machi'neofknown type provided with {vi a presser plate 18, a gage. 20, awork penetrat- I in Figs. 1 and 2, and thus extendingtrans versely of the grain of the wood when oper ating in the vicinity of the breast cornersof' the heel, Thus the edge of the chisel point 32 of the awl will engage'the top lift along such a line as-is indicatedat ge in 1. 1 r The use of an awl having a chisel point of this character not only substantially eliminates the splitting of wood heels, but also servesto force thefibre of a leather top lift down below the surface of the wood of the heel at opposite'sides of the fastening 30 as illustrated at 36in Fig. 4:. This action is accomplished by means of the inclined surfaces 38 and 4:0 on opposite sides of the chisel point 32'of the awl, and does not take place, at

'least to. any substantial extent, as viewed upon planes defined by the axis and the edge of the chisel point of the awl. This forcing of the fibre of the-leather top lift down below the surface of the wood of the heel makes a much more secure attachment than would otherwise be provided, locking the fastenings in the wood and preventing the top lift from working on the wheel when the shoe to which the heel is attached is worn.

Having thus described my invention, vwhat I claim as new and desire to secure by Letters Patent of theUnited States is:

1. That improvement in methods of attaching top lifts to wood heels which comprises holding a top lift and a wood heel in assembled relation, making holes through the top lift into the wood of the heel with an awl having a'chisel point positioned with its edge extending in a direction substantially normal to the edge of the heel, and inserting fastenings in the holes thus formed.

2. That improvement in methods of attaching top lifts to wood heels which comprises making holes through a leather top lift into a wood heel with an awl having a chisel point positioned with its edge substan tially normal to the edge of the heel and thereby forcing the fibre of the leather of the with an-awl having a chisel point, with the edge of'the chisel point of the awl extending transversely of the grain of the wood-'ofthe heel, and inserting-fastenings in the holes thus formed. .a I a v '5; That improvement in methods of attaching leather top lifts to woodheels' by paper pegs inserted through thetop lifts into the heels characterized by forcing the, fibre of the leather adjacent to the paper pegs downwardlyrbelow the surface of the wood of the heel-at opposite sides'of the pegs.

6. A wood heel having a leather top lift attached thereto by paper pegs inserted through the top liftinto the heel, the fibre of the leather adjacent to the pegs being forced downwardly below the surface of the wood of the heelat opposite sides of the pegs.

In testimony whereof I have signed my name to this specification.- I
