IMPROVEMENT m MACHINERY FOR HEELING Boers AND SHOES.

Speci ficati on forming part of Letters Patent No. 147,5 l3, dated February 17, 1874; application. filed January 12, 1 874.

- new and useful Improvement in Machinery for Heeling Boots and Shoes; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, which denotes a side elevation of a jack provided with my improvement.

' My invention has reference to what is known as the McKay heeling-machinc; and consists incombining, with the jack or last-holder of such machine, an attachment or device, as hereinafter described, whereby the fixation of a heel having a blind. top lift is effected with much greater facility than. by the method heretofore adopted.

As my invention has sole reference to a device to be attached to the jack of such machine, itis not deemed necessary to show the other parts thereof.

I would remark that in the said lieclingmachine the jack or last-holder is affixed to a head or carrier which is capable of being adjusted vertically by means of a handwhcel and a train of gears affixed on the top of the machine.

Under this arrangement, a boot or shoe which is to have a heel affixed to it provided with what is termed a blind top lift --that is, one in which the outer lift is secured to the under lifts by nails project lug-from the latter, and partially through the top lift, so as to leave the outer surface thereof smooth, or without showing the means by which it is secured to its fellow lifts -requires the jack to be twice adjusted in the fixation of each heel; first, to locate the sole of the boot at the requisite distance from the nailing and compressing mechanism to receive the under lifts, and enable such to be secured to the sole and duly compressed; and, second, to place it at such greater distance from the said mechanism as to receive the blind top lift, and allow the compressing mechanism to affix it to the under lifts, and to compress the whole with the required degree of pressure.

These adjustments of the jack are governed. solely by the judgment of the operator, and require much care and skill to produce the proper fixation and compression of the heel.

By my invention, after the jack has been once adjusted to the grade of shoes, any number of heels may be affixed without further adjustment of the jack.

In the drawing, A denotes the jack-block, and B B two standards or posts projecting down therefrom, and having a shouldered tenon, a, formed on the lower end of each. I) is a steadying-plate, which is slipped over the tenons, and rests on the shoulders of the posts B. The tenons a a enter corresponding holes in the last, and serve to hold the latter in position; all of such parts con stituting the jack, and being constructed of metal, in the ordinary manner. 0 is a gage plate or block, which is hinged or pivoted to one end of a pitman, cl, whose other end is pivoted to a clamp, c, secured to the base of the posts B, as shown in the drawing; or such pitma-n may, if desirable, be pivoted to the under surface of the jack-block A. The said gage is bifurcated, so as to straddle the last tenons hereinbefore mentioned, and has a width eorrespondin g with the standard thickness of the blind lift forming the outeror tread surface of the heel.

In using my invention in affixing the foundation heel or under lifts to a sole, the gage-block is made to straddle the tenons a a, and rest upon the plate b, as shown in the drawing. The last is next affixed to the jack, its upper surface resting upon the gage-plate. The jack having been previously adjusted at the proper distance from the nailing and compressing mechanism, the under lifts are affixed and secured to the sole in the usual manner. In aiiixing the blind top lift, the latter is placed upon the heel-plate in the ordinary way, and the gage-plate next drawn back, as shown by dotted lines in the drawing, when the compressing mechanism,b ein g brought into operation, forces the last up against the plate 1), at the same time securing the top lift, and compressing the whole heel to the requisite compactness.

From the above it will be seen that by the employment of my invention, the jack once having been adjusted with respect to the nailing and compressing mechanism, no further adjustment thereof becomes necessary in the fixation of any number of heels, While Without the same two adjustments thereof are required in the attachment of each heel.

, It will also be seen that such not only effectsa great saving in time, but causes the pressure exerted upon the heels to be unvaryingly uniform.

What I claim is- The combination of the pivoted gage-block (J with the jack or last-holder of a boot or shoe heelin g machine, substantially as and. for the purpose set forth. r
