To all whom it'mag concern Be it known that JOHN EL Gnmnnn, of Beverly, in the county of Essex-- and" State of h iassachusettsy insane, invented certain- Improvements in HeeLDies; of- Whichthe following description; in connection withthe accompanying drawings, is a SPGClfiCBr' tion, like reference characters onthe draw ings indicating like parts inthe several fig: ur'es.

This invention relates to-diesf'or building heels, and more particularly to dies for cut ting out lifts and parts of lifts frompieces of leather or the like, the dies serving: as receptacles into" which: the died-out piecesare pressed and in: which these piecesare compactly arranged to form heels for boots and shoes.

Dies of the type to Whichthis invention particularly relates are knoWn comm'er cial'ly as Haverhil-l-heel dies; These dies are 1 usually fixedupon a benchor table with their cutting edges extending upwardly therefronn and in practice the pieces of leather to'be out are laid' upon the cutting edge: of the die and then died-out by being: forced downwardly againstthe cutting edge by a mallet or other similar hand operatedinstrument. Waste scraps of leather of i=r regular form and of Varying sizes and slia'pesare; utilized, such, for example,-, as are left fromthe operations of dieing out soles, heel lifts and the like from sides oflea then Whenenough sections of leather have been cut and compactly forced downinto the die to" fill: it completely,- one or more heel nails are driven to hold the different s'ections of theheelfirmly together. Before the built-upheel i'scom'pressed it is frequently provided with a Wholeor onepiece heel seat lift of leather or of leather board and afterward; during the heeling I operation, a Whole outer or top lift isusui all y' blind nailed: thereto, thesejjone piece li-fts' assisting nra'teriall-y inholding the intermediate sections of scrap leather securely place; In certain classes of Work; hoW- ever; it is desirable to have the-finished heel present similarly inclined breast and faces, the breast slope being usually inwardly and rear-Wardl-y; and the pitch at the back being outwardly and rearwardly from the outer lift to the heel seat- A specification of LettefsPatenti Patented res;-

icorcling lya principal objectof this inven= tlon IStOPFOV'i'ClQ a die of: the character de=- scribed by the use-of whichan undercutor in ardl'y inclined heel b1-east can-be' secured and at the same tlmea snmlarslope'canbe given to the back of the heel;

In the embodiment of this invention herei in shown: and described in connection with a die of: the typeabove-mentioned; this and other obj eots and advantages hereinafter set ifft'h, are attained by inclining or tippingboth therear and-breast walls of the die, the slope of the front or: breast Wall" being pref erably in thesaine direction as that of the l rear Wall; irearwalls of the die; particularly if the By" so inclining the breast 'and' ngle of 'lTiClillfl'flOIl at the-rear be substantially equal to that at the front,-heels can be built up-by superposing? lifts of suhstanti-ally the: same area and the desiredpitch at back and front-can be obtained, the suc''-' cessive lifts being displaced: toward the rear relatively to each other astli'ebuildi-ng operation pro-gresses. In order thatthebreast slope thus obtained may not be destroyed: in the compressing operation as would be the case if a vertical-- breast platewere employed; a heel having inclined breast and rear surfaces-may compressed in a mold having an inclined breast plate, suchforexample, as that described in United State's Letters Patent tQ- L11I1Cl= No. 974555,- dated Nov-em herlg- 191-0, in which case the breast slope will be unimpaired by the compressing 013,- oration.

- A s further feature of the present inventionconsists in the resulting. economy of stock 1 eifectednby its use inproducin'g: certain-kinds of heels,- p articularly those infen'de d to; have permanently inclined breast faces:- While' it" is poss ble in the breasting operating-to in cline; the breast face simi-larly' to the pitch of the rear, it: is much more economical so- Etobuild and compress the heel: that, prior to'the breastin'g the contour oftheheel may approximate as closely as possibleits fin iished form, in order to reduce thee-mount Q of waste stock; removedin=breastingi From the frontor breast edge of the heelseat to ithe breast edge of the outer lift the slope- 'will be practically that desired in the fin;

ished= heel and hence there Will bea minimum of waste to be removed by the breaster.

Indeed, in cheap grades of work a very satisfactory breast can be obtained merely through the compressing operation without any breasting whatever, provided the heel is built and compressed with its breast face presenting substantially the contour desired for the finished heel. Preferably the angle of inclination of the front of the die will be substantially the same as the angle of inclination of the rear, since this construction gives the best results in obtaining properly directed and suflicient pressure to effect the desired rear pitch and because in finished heels which present a final slope it is usually desired that thebreast pitch shall closely approximate the rear pitch, both in direction and in extent.

Another feature of the construction contemplated by this invention results from the fact that the tilt of the die giving to its cutting edge an oblique cut through the superposed leather largely diminishes the resistance of the leather to the die. This not only facilitates the cutting, but also tends to leave the cut edges of the leather clean and free from outstanding ragged fringes. Moreover, the oblique cut prolongs the life of the die by lessening the liability of breakage, particularly at weak points such as the corners between the curved edge and the straight edge where experience has shown that the die is most liable to break down and by insuring that the cutting edge of the die will not be so frequently and easily dulled.

These and other features will appear from the following description of a preferred embodiment of this invention read in connection with the accompanying drawlugs.

Referring to the drawings: Figure 1 is a view in perspective of a die in which the present invention is embodied. Fig. 2 is a View in perspective of a heel built up by the use of the die shown in Fig. 1. Fig. 3 is av longitudinal vertical central section of the die shown in Fig. l but on a smaller scale.

The heel die in connection with which one embodiment of this invention is shown for purposes of illustration has a base 2 provided with recesses 4 adapted to receive clamping bolts for removably securing the die as desired to a table or bench. Lugs 6 upstanding from the base 2 and conveniently cast integral therewith, are threaded at 8 to receive screw threaded bolts 10, the bolts 10 bearing against opposite sides of the body portion of the die and securing the die in position on the base 2. The die comprises a hollow body portion which consists of a wall 12 upstanding from the base and an ejector 14 which, as shown, is a paddle loosely fitting the interior of the die and provided with a handle 16 arranged to project outwardly through a slot 18 in the front of the upstanding wall 12. The under side of the paddle 14 has a thickened portion which rests normally upon the base plate 2. This paddle 14 normally serves as a bottom plate for the die on which the heel seat face of the heel is formed but it is arranged to be raised by means of the handle 16 to eject the built up heel from the die when desired. The wall 12 is formed with a straight front or breast face 20 and a U- shaped or curved rear portion 22, and has its upper edge 24L sharpened for cutting.

It will be observed by reference to Fig. 1 that in accordance with the present invention, the wall 12 is inclined forwardly at the front and at the rear so that the front face 20 of the wall 12 and the rear portion 22 are both tipped forwardly and so that the wall 12 at the rear overhangs a portion of the base plate 2 with the result that the built up heel shown in Fi 2, in which 26 represents the outer face of the heel to which the outer or top lift is to be attached and 28 and 30 the breast and rear faces respec tively, will have its breast and rear faces sloping rearwardly and inwardly from the outer lift to the heel seat, and so that the pitch of the rear 30 will extend in the same direction as the slope of the breast 28.

As shown in Fig. 1, and as above suggested, the die is conveniently made with the angle of inclination of the rear portion 22 of the wall 12 substantially the same as the angle of inclination of the front or breast wall 20, with the result that the dif ferent layers or lifts are of approximately the same area, this arrangement being both commercially desirable and productive of economy of time and of stock in cutting out the lifts or parts of lifts.

It should be noticed that although preferably the die will be constructed with its wall forwardly inclined it could equally well and entirely within the spirit and scope of this invention be made with its wall backwardly inclined, in which case, of course, the process of building the heel would be exactly reversed, that is, the heel would be built up with its top or outer portion 26 formed on the ejector 18 and its heel seat face at the top of the die. Or and equally within the invent-ion, the die could be formed with the angle of inclination of its front face difierent from that of the rear face. Various other modifications such as would readily occur to those skilled in the art could be made without departing from the present invention as shown and described herein purely by way of illustration and not by way of limitation.

In operation, the workman selects from a miscellaneous assortment of scraps of sole leather and the like such pieces as will out to advantage, holds the selected pieces over the cutting edge of the die or over a portion thereof and forces the leather down over the die by means of blows of the mallet, continuing this mode of operation until the die is filled up and using the mallet to hammer down the stock compactly so as to form a firm and well knit heel. As the leather sections are forced downwardly into the die by reason of the slope of the breast wall 20, and the inclination of the rear wall 22 there will be a crowding rearwardly so as toexert a suliicient compression to effect the desired pitch of the rear as above explained. WVhen the heel has thus been built up in the die, a number of heel nails are driven through at various points as above explained, and the heel is then ejected from the die, the operator commonly hitting the handle 16 of the ejector 14 a sharp blow with the mallet thereby raising the paddle let to eject the heel.

Having now fully described the present invention as preferably embodied in one illustrative construction, what is claimed as new and desired to be secured by Letters Patent of the United States is 1. A heel building die having an upstanding wall formed with front and rear portions obliquely inclined from the horizontal inthe same direction, the said wall being provided with an upwardly extending cutting edge.

2. A die for building heels having inclined breast and rear surfaces, said die having an upstanding wall provided with an inclined rear portion formed to project over a part of the interior of the die, and a forwardly inclined front portion, said wall having an upwardly extending cutting edge.

3. A heel building die having an upstanding wall formed with a U-shaped portion at the rear and a straight portion at the breast, both said portions being inclined forwardly whereby successive lifts are displaced toward the rear relatively to each other as the building operation progresses.

4. A heel building die having an upstanding wall with an upwardly extending cutting edge and formed with forwardly inclined rear and breast faces, the angle of inclination of the rear face being substantially (iqual to the angle of inclination of the breast ace;

5. A heel building die having an upstanding wall curved at the rear and straight at the breast, said wall having its rear and breast faces both inclined in the same direction.

6. A heel building die having an upstanding wall, U-shaped at the rear and straight at the breast, and a heel seat plate constituting the bottom of the die, said 'wall having both its rear and breast faces inclined obliquely to the plane of said heel seat plate.

7. A heel building die comprising an upstanding wall having rear and breast faces both inclined in the same direction and at substantially the same angle to permit a heel with inclined rear and breast surfaces to be built up therein by superposing lifts of substantially the same area. 7

8. In a die for building pieced heels the combination of an upstanding wall provided wit-h a cutting edge and having rear and breast faces both inclined in the same direc-' tion, abottom plate normally constituting the bottom of the die, and means for raising said plate when desired to eject the built up heel from the die.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
