HEEL-BEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 388,790x dated August 28, 1888.

Application {led May 2Q, 1388. Serial No. 274,633. (No model.)

To :LUI whom it may concern:

Be it known that I, JOSHUA H.. RYDER, of rockton, county of Plymouth, State of Massachusetts, have invented an Improvement in 5 Heel-Beading Machines, of which the following description, in connection with the aecompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to construct [0 a machine for beading heels of boots and shoes.

My invent-ion consists, essentially, in the combination, with a rand-guide, ofa heel-beading tool having one or more canrlike or striking surfaces,\vhich in the rapid rotation ofthe rand-guide act in succession upon or strike against the heel and form thereon a polished bead next the rand-crease; also, in the combination,with the rand guide and a heel-beading tool, ofa heel-rest; also,in the combination,

with the rand-guide and its shaft,of a friction heating device for the shaft to which the randgude is secu1ed,whereby the rand-guide and heel-beading tool are kept heated. The heelheading tool which I prefer to employ has 2 5 Several camshapcd striking surfaces or projeetions, which are adapted to successively and rapidly strike or act upon the heel to bead it, said projections being formed by cutting away chords of the hub oi" the tool. The heel-rest 0 is larger in diameter than the shortest diameter of the heel-beading tool, so that only the rounded projections are permitted to act upon the heel.

Figure l shows in front elevation a heelbeading machine embodying this invention; Fig. 2, a sectional detail ofthe randguide and beading-tool together with a part of the shaft ou the line az, Fig. l; Fig. 3, a detail of the beading-tool and the randguide on the line c Fig. fi, a detail in the line a" ofthe heel-rest mounted upon the rotating shaft, and Fig. 5, a sectional detail of the friction heating device.

The main frame or support A, of suitable shape to sustain the working parts, has at its upper end suitable bearings, ff, for the rotating shaft I3, mounted in suitable bearings and having a belt-pulley, C, fixed to one end thereof. The shaft B near its opposite end reo ceives upon it loosely a heel-rest, c', having a milled or roughened edge or surface by which to score or indent the heel, the inner end of the said heel-rest being red ueed to form a sleeve, ai", which enters and takes bearing in a chamber bored out of the hearing f. rand-guide l) and heel-beading tool c, preferably made in one piece, are iixed by screw b to the end of and rotate with a shaft, B. The heel-beading tool chas rounded or cam-like projections c', herein shown as six in number, they being formed by cutting the hub of the randlguide to remove chord-like projections thereon and form lat sides or faces, the point wherein two of the flat sides or faces moet being rounded. The milled portion of the heelrest c is larger in diameter than the short diameter of the heel-beading tool, but smaller in diameter than the largest diameter of the said heel-beading tool,so that only the rounded projections c are permitted to strike against the bead of the heel.

I do not desire to limit myself to any particular number of projections c.

By this construction the heel is subjected to repeated blows of the projections c', and as the shaft B is revolved at a very high speed and with several such rounded projections employed the bead may be formed very quickly and very smooth. rlhe heel is pressed against the heel-rest a by the operator holding the shoe in hand, the milled teeth of the edge c' entering the leather to form a series of indentations.

The friction heating device herein shown consists of a plate or ilat strip of metal, B, attached at one end to the framework, the opposite end having secured to its under side a piece of leather, as d,which bears directly upon the shaft B. The friction will be regulated by the adj estiment-screw di. As the shaft B is revolved, the friction of the leather d on the said shaft will heat it, and will also heat the beading-tool sufficiently to prevent Wax or other material adhereing to the parts.

I do not desire to confine myself tothe pan ticular construction of friction heating device, as it may be changed somewhat and still sub serve the purpose herein designed.

Prior to my invention the work which my machine is to perform has been done by a tool The ICO

having a motion around the heel from breast to breast.

I am aware that burnishing-machines have been constructed having a rand-guide and a separate burnishing-sleeve, the sleeve being provided with cani projections, intermediate adjusting mechanism therefore, and a clampscrew to secure the same, and such construetion I do not claim. rIhe result obtained by forming the heel-beading tool and rand-guide inA one piece, as hcreinbefore set forth, is that the bead will always be formed in the correct or proper place, whereas when made of two pieces it is difiicult to properly and rapidly adjust the parts relatively, and even when so adj usted they are liable to get loose, owing toA and having one or more cam-like surfaces or projections, as c, substantially as described.

2. The rotary shaft B andthe rand-guide I),

combined with the heel-beading tool having cam-like surfaces or projections c', and the independent milled edge heel-rest a, substantially as described.

3. In a heel-beading machine, the following instrumentalities: the rotary shaft B and the randguide b, a heel-beading tool, e, fast thereon, Combined with the heelrest a, having the milled or roughened edge a and loose on the shaft B, substantially as and for the purpose set forth.

4. In a heel-beading machine, the following instrumentalities: the rotary shaft B and the rand-guide b and heel beading tool c, fast thereon, combined with the heel-rest a, having the milled or roughened edge a and provided with a sleeve-like extension, as, which turns in a bearing in a part of the frame-work independent of the shaft B, substantially as described.

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

JOSHUA I-I. RYDER.
