Application January 12, 1937, Serial No. 120,196 2Claims. (01. 145-128) My invention relates to the attachment of heels to shoes.

In attaching heels to shoes, practice to apply a temporary fastening device to a lasted shoe and its heel to draw the heel against the heel seat portion of the shoe, and

then later remove the temporary fastening device and replace it with a permanent fastening device such, for instance, as a screw.

In my improved method of attaching heels, it is an object of my invention to employ .but ofie v fastening device, a wood screw, and itsapplication to the shoe, and heel therefor is permanent, thus eliminating the usual temporary fastening step,

is and, to this end', I employ the usual last having a heel section provided with a thimble hole for jacking the' last, and I provide the heel section.

of the last with an inclined bore extending from the upper face of the heel section to the lower face of the heel section. I also provide the lower,

or heel seat face of the last with a metal plate having a hole of less diameter than. the inclined bore in the heel section, and, which hole 'is in axial alignment with the bore to provide a shoultached thereto, and, to simultaneously countersink the .upper end of the hole, and a tool to force a screw into. the hole and move it into home position for permanently securing the heel to the 35 shoe. g v

The manner in which the above and other ob-.i

. jects of the invention are secured,'and the means it has been the Fig. 41s afragmentary sectional view of the heel portion of a shoe last and a metal plate secured thereto having an cpeningof less diameter than the opening in the heel portion of the shoe last to provide a stop shoulder for the opening'pro- 5 I testing device.

' shoe last, said tube being removable from the 10 opening.

Referring to the drawing, the reference numeral 3| designates the heel portion of a shoe last which maybe of the usual type provided with a thimble hole 2 for jacking the last, except for such other II constructional features and associated parts as hereinafter fully described as pertaining to my present invention.

In carrying out my invention, I provide the heel section I of the last with a bore 3 between the $0 thimble hole 2 and the rear face 4 of the heel portion of the last. The bore 3 extendsfrom the top face of the last to and through the lower face of the last, and the bore is disposed at an angle to the axis of the thimblehole 2; or, in other as employed, will be apparent from the following description,-',and 'the accompanying in which:

Fig. 1 is a fragmentary sectional viewshowing the heel portion of shoe last with a part of a shoe mounted thereon, and the last being' provided with devices for protecting an opening in the heel portion of the lastand a tool to drill a hole maheehtobesecuredtotheshoebymeanscf ajscrew, as-wellas counter-sinking the materialof the heel seat portion of the shoe.

Fig. 2 isaviewsimilartoFigLliutshowing 50 device for protecting the opening in the last as unsecured to the drilling and eountersinking device.

Fl g. 3 ma view similar to Fig. 2, showing a words, it converges at its lower end toward the V axis of the thimble hole 2.

I provide the lower face of the heel section of the last with a metallic nail clinching plate 5, which'is suitably secured thereto, and the'plate so 5-is provided with an opening '6 in uial alignment with the 'axisof the bore 3. The plate opening 5 is of less diameter than the vbore 3 and the plate at'the edge portion of the opening therein serves to provide. a stop shoulder l for a a removable tubular metal lining, or sleeve I for the bore 3.

, The tubular lining or sleeve l,'in one .embodiment ;of the invention is associated with a tool embodying a shank 8 having a longitudinal bore l0 therethrough. The lower face of the shank 9' device within the opening protecting device for 5 securingascrewtotheheelofashoe.

is formed to provide a bevel, or countersink cutter ii. The upper end of the shank bore ll is screw threaded to receive screw 12. Asteel shaft I3 is disposed within the bore II below the adjusting screw l2, and the shank ll, of a suitable drill I5, is receivable in. the lower end of the bore with the drill l5 projecting'beyond the countersink cutter II. The drill shank is held against rotation relative to the tool shzanlr 9 by means of a set screw 16, and it is held against upward movement into the shank bore bythe steel shaft l3 and the adjusting screw II.

A suitable stop collar I1 is mounted on the tool II on one race thereof, which is adapted to receive the upper end of the tubular member 8. The tubular member 8 is provided with an opening I 9 through which a set screw 20, carried by the collar l1 passes for ,end contact with the tool shank I. The screw 20 holds the collar I1 in-its adjusted position on the tool shank 9. When the drilling and countersinking tool is thus provided with the tubular member 8, it can be inserted, as a unit into the bore 3 of the shoe last and the lower end of the tubular member stops and rests against the metal plate shoulder 1 at the edge of the plate opening Ii. When in this position in the bore 3 of the last, it'will be observed, that the tubular member 8 resting on the shoulder 1 prevents the hole in the heel being drilled too deep, likewise the countersink in the heelportion of the lasted shoe. Further, the tubular member 8 serves to protect the bore against injury or wear as the tool is rotated in the bore 3.

It will be apparent that when the collar I1 is reversed on the shank 9, that the tubular member does not rotate with the shank 9 and thus does not rotate in the bore 3, but merely serves as a removable liner therefor. It will beapparent from the drawing that the collar II, as well as the tubular member 8 are" removable from the .tool shank carrying the drill and countersink cutter and can be attached to ascrew driver shank 2|. when-used with a screw driver, it is apparent that it is for the purpose of forcing a fastening screw through the heel portion of the shoe and into the drilled opening in the'heel forp'ermane tlyfattaching the heel. to

the shoe. a The many advantages of the herein described exercise of invention,

from the spirit of the invention within the scope oi the appended claims. a

What I claim is:

1. A tool for use with a shoe last having a bore'therethrough and a plate having a hole of less diameter than the bore. to provide a metal shoulder, said tool comprising a shank having a longitudinal bore therethrough, a drill insertable into the bore from the lower end thereof, the upper end 0! the bore being screw threaded, a screw threaded into the screw threaded bore and serving as a stop for the upper end of the drill, a set screw carried by the shank for preventing rotation of the drill relative to the shank, a countersink cutter formed on the lower-end oi the shank, a sleeve mounted on the shank, a gauge collar'having a bore to receive the shank and having a bore'oi larger diameter to receive the upper end of the sleeve, and a set screw insertable through a screw threaded opening in the collar and an opening in the sleeve for vertically adiustably securing the sleeve to the shank to prevent rotation of the sleeve relative to the shank and to cause the lower face of the sleeve to serve as an annular shoulder adjacent the countersink cutter to engage said metal shoulder 'on the last, and said collar being reversible on the shank to serve as a stop to act against the upper end of the sleeve when the sleeve is used asaguidetortheshanktopass throughandto turn in when the sleeve is used as a removable lining for the'last bore so that the shank can turn relative thereto instead of therewith.

2, A tool of the class described having. in combination, a shank having a longitudinal bore therethrough. a counter-sink cutter formed on the lower end or the shank, a drill insertable into the shank bore, means for adjustably securing the 'dl'ill in position, means adJustably carried in the bore of the shank serving as a stop for the inner end of the drill, a sleeve mounted on the shank, a reversible collar adiustably secured to the shank to serve as a stop to limit downward movement of the shank relative to the sleeve, and means for connecting the sleeve and the collar to rotate as a unit when desired.
