COUNTER-STIFFENER MACHINE.

SPECIFICATION forming part of Letters Patent No. 286,432, dated October 9, 1883.

Application filed August 17, less. (No model.) 7

To all whom it may concern:

Be it known that I, J litres L. Huron, of Rochester, county of Monroe, and StateofNew York, haye invented an Improvement in Machines for Elongating and Finishing Counter- Stiffeners for Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

IO In the manufacture of counter-stifi'eners the leather or leather-board, cut into the proper shape, is rolled or flanged between a revolving and a stationary mold, which leavesthe counter stifiener in a too-nearly circular form to fit the heel of a last, and thereafter the said rolled counterstiffener is molded between firm, rigid,

, hinged jaws of a divided mold, the latter clamping the stiffener to the form, while a V- shaped slide irons and sets the flange. In my experiments to produce a counter-stiffener to fit the human heel, I have discovered that the said stiffener may be greatly improved in shape I by stretching the same at its sides on the same machine which irons and sets the flange. To 2 this end I have combined with the heel-like form on which the rolled stiffener is placed and held an. impinging follower and a con neeted clamp composed of one or more springs, which act upon the outer sides of the rolled o stiffener placed on the said form and stretch and elongate it from its media-n line along its sides, and in connection with the same I use a horizontallyreciprocating V-shaped slide by which to iron and smooth down and set the 3 5 fiange partially set in the rolling process.

Figure 1 in top view, represents a machine containing my improved apparatus for elongating and finishing counter-stiifeners, the stiffener being shown in dotted lines. Fig. 2 40 is a longitudinal section of Fig. 1 on the dotted line as x, the guide for the V-shaped slide being, however, omitted; Fig. 3, a crosssection on the dotted line a? of, Fig. 2. Fig; 4 represents a stiffener as taken from the rollingmachine to be stretched and finally shaped by the machine herein described. Fig. 5 represents a finished stiffener; Fig. 6, a section of Fig. 1 on line 00 a, and Fig. '7 a section of Fig. 1 on line so".

The heeli'orni A composed of cast metal and of suitable size, according to the stiffener to be elongated and finished, rests in a groove,

a, in the bed-plate B, and slides therein more or less, as the stiffener is acted upon by the stretching-clamp G. The heel-form has abolt or rod, I), which is entered through a rigid upright part, If, of the usual'frame-work, A and through a suitable spring, 1), preferably of india-rubber.

The follower D, forming part of the stretching-clamp, is made as a solid block, concavcd at its frontend and wider at top than at bot tom, (see Fig. 6,) thus giving to it verticallyinclined faces, is attached to a suit-able rod, D, which, in practice, will be guidedin a suitable bearing, 2, one or more, and will be reciprocated longitudinally by means of a suitable cam, A, the face of which receives a pin or roller, 4, attached to the slotted part D of the rod D, the shaft A3, to which the said cam is attached, being extended through the slot in D This follower has attached to it the steel springs s s of the clamp, each spring being connected with the follower D by suitable bolts, 5 6, and preferably connected therewith in an adjustable manner by making the central part of the side faces of the follower D, between the bolts 5' 6, higher than at the said bolts, (see Fig. 1,)so that adjustment of the bolts 5 6 will enable the free or front ends of the springs s s of the clamp to be more or less separated; and so, also, to stiffen the said springs, the bolts may be moved to more or less bend the springs over their fulcra. It will also be understood that I may stiffen the springs, if desired, by adding a leaf of spring outside each spring 8, as wagonsprings are commonly stiffened, the outer end of that stiffening-leaf not, however, being extended but little beyond the bolt 6.

The main shaft E of the machine, having suitable hearings in standards mounted on the frame-work, has a pinion, E, which engages a tooth-gear, E fast on the cam-shaft A at the side of the cam A, before described. The shaft A has fast at each end of it a crank, 10, which, by link 12, is jointed to a carriage, E. The links 12 are connected with this carriage at each side of its center, and the carriage provided with suitable projections, f, which are fitted under cap-platesf which thus act as a guideway for the carriage as it is reciprocated by the said cranks and links.

The carriage E has attached to it by bolt 14 the V-shaped slide F, which is moved forward horizontally above the heel-form and clamp to iron down, smooth, and set the flange of the counter. The'forward part of the V-shaped slide is guided in a guide-plate, S, provided at its under side with a dovetail or other suitable groove to receive the said slide.

The plate Sis held down by springs S acted upon by suitable nuts, 20, on bolts 21, by which to adjust the strength of the said springs, and thereby permit the slide F to rise more or less, according to the thickness of the turned'over or flanged part of the stiffener.

The rolled stiffener it (see Fig. 4) having been placed upon the heel-form A, the clamp will be moved forward, and the curved end of the springs will first impingeagainst the stiffener at about the line g y, and will then spread as the clamp is being moved forward,

and will slide over and in contact with the said stiffener on theheelform until the springs reach thethickest part of the heeLform, which is in the line a 2, at which time the stiffener is subject-ed to the greatest elongation or stretching strain from its back vertical center or median line. After this the free ends of the springs are gradually permitted to approach each other, following in and hugging closely to the outer side of the stiffener supported upon a thinner part of the heel-form, stretching, smoothing, and elongating the said stiffener from the said line 2 forward to its ends.

If, desired, I may relieve the pressure of the springs on the stiffener as the clamp is drawn off backward. To do this the lower edge of each spring will be provided with an incline to strike against a roller or stud, which will be thrown up in the path of the backwardlymoving clamp. The clamp having been moved fully forward, as in Fig. 1, and the springs s 8 having acted upon the sides of the stiffener and stretched and fitted it to the contour of the heelform, the slide F will be moved forward until its V-shaped end passes beyond the corners of the flanged part of the stiffener, the said slide, by its downward and forward pressure,which may be varied in amount as desired, ironing, smoothing, and setting the flange of the stiff ener. As the clamp reaches its extreme forward position the concave face of the block D strikes and presses the stiffener at and about its median line closely against and about the end of the heel-form. The downwardly and inwardly beveled sides of the block D enable the springs s s to be placed in an inclined position, so as to hug closely against the stiffener outside of the thinnest part of the heel-form, thus drawing it in to insure a proper adaptation of the upper or unflanged part of the stiffener to the natural heel.

Referring to Fig. 6, it will be seen that the heel-form is made narrower opposite the curved top edges, ha, of the stiffener h. To enable the part h of the stiffener to be fitted closely to the heel-form, the sides of the follower D from top to bottom are beveled inwardly, so that the lower edges of the springs s are closer together than their upper edges, and the springs inclined inwardly, as in Fig. 6, are enabled to flt the counter-stiffener closely to the tapered narrower thin parts of the heel-form.

I claim 1. The heel-form, combined with the fol lower D and its attached springs s, to shape the stiffener to the heel-form, substantially as described.

2. The heel-form and the reciprocating follower D, combined with the springs s, and with screws to adjust them upon the follower, substantially as described. A

3. The heel-form, made thinner below its upper part, upon which rests the flange of the counter-stiffener, combinedwith the springs having their low er edges inclined inwardly, to act upon the entire sides of the stiffener from its flanged portion to its curved or top edge, substantially as described.

4. The heel-form and the reciprocating follower, and springs to act directly upon the counter-stiffener placed on the said form, combined with the reciprocating slide F, to iron and set the flange of the stiffener, substantially as described.

5. The heel-form, the reciprocating follower, and springs to act upon the outer sides ofthe counter-stiffener, and the slide F, to iron and set the flange of the stiffener, and the carriage to move the said slide, combined with means, substantially as described, to vary the downward pressure of the slide F upon the said flange.

In testimony whereof Ihave signed my name to this specifi cation in the presence of two subscribing witnesses.
