SJCIFICATION forming part of l'retterslafCt-illit No. 279,717, dated June 19, 1883.

` Application filed April 2, 1883. (No model.)

Be it known that I, LOUIS COT, of St. Hyacinthe, in the county of St.' Hyacinthe and l Province of Quebec, Canada, have invented certain new and useful Improvements in Machines for Shaping Boot and Shoe Counters, of which the following, taken in connection with the accompanying drawings, is a specification. l

My invention relates to certain improvements in the process of and machinery for shaping counter-stiifeners or heel-stiffeners for boots and shoes; and it consists in a novel method of imparting to the counter-stifeners blank the desired shape, and to certain novel constructions and arrangements of mechanical devices whereby the machine is adapted for reshaping a counter-stiffener, or, in other words, for completing the shaping of a counter which has already been subjected tothe action of rolls or revolving dies whose transverse section is circular, and has been brought to a similar circular form, whether or not the iiange has already been formed on said counter-stiffeners.

It further consists in a novel arrangement for holding the stationary dies or molds, ad`

given to the work, all of which will be best understood by reference to the following description of the drawings, and to the claims to In the drawings, Figure l is a perspective vview of a machine embodying' my invention. Fig. 2 is a perspective View of a portion of the same, looking from aslightly-different di- Fig. 3 is a vertical section taken through the center of both sets of dies. Fig. 4i. is a partial. vertical section online on Fig. 3, and Figs. 5 and 6 arel respectively an elevation and edge view of a disk or wheel adapted to receive and carry a flanged counter-stiffener.

Similar letters refer to similar parts in the different figures.

A is the frame of the machine, upon the rear side of which is a driving-shaft, B, mounted in suitable bearings, and carrying at its rear` end the fast7 and loose pulleys B and'Bi, adapted to receive a suitable driving-belt.

C is a shaft mountedin bearingsA/ A of the frame A, and having secured upon its rear end the spur-gear wheel C', which engages Vwith and receives motion from the pinion B",

in conjunction with the stationary die or mold.

E to shape the countergstiffeners from suitable blanks, the shape of the former D and mold E and the action thereof upon the blank being substantially the same as described in reissued Letters Patent No. 7 ,356, granted to me October 24, 187 6. The mold E is held and adjusted in an improved manner, as will hereinafter be described.

Upon the shaft C is secured the pinion C2, which engages with and imparts motion to the gear-wheel F, mounted loosely upon the driving-shaft B, and revolving independent of the motion of said shaft. The gear-wheel F has secured thereto the pinion F, which revolves with it and engages with the gear-wheel G', secured firmly upon the shaft G, mounted in bearings A A2 'in the frame A.

Upon the front end of the shaft G' is secured the disk or wheel H, having a rounded edge roughened or serrated to secure a iirmer'hold upon the counter-stiffeners while being shaped.

J is an adjustable mold, partially surroundingV and inclosing the upper portion of the wheelfH, and provided with a Haring mouth at a., to facilitate the introduction of the counterstiffeners between it and the wheel H. The concave surface of the mold J, against which the counter is pressed by the rotation of the wheel H, is made very smooth, its upper surface being brought into close proximity to the edge of said wheel, and curved so as to be e011- centric, or nearly so, therewith, except at the moutha, as shown vin Fig. 3. The side portions of said concave or working-surface of the mold J are made somewhat iiaring, as shown in Fig. 4, admitting of a greater or less space between4 them and the side of the wheel H, acy vided with a hollow threaded shank, l, upon which is screwed the nut K. The shank I' IOO passes through a slot, I), Fig. 2, in the ear or I shelf b of the frame A, the shoulder yd of the socket I bearing against the under side of said shelf 5 and the nut K, being screwed down tight upon'the upper side thereof, serves to hold the socket securely in position.

Within the socket I is a disk, c, provided with a tubular shank, f, which passes through the hole in the shank I of the socket I, and has screwed upon its upper end the nut g. Above the disk e is a ring, 7L, of rubber or other suitable elastic material. Through the center of the tube f extends the rod i, having a screw-threadA at its lower end, which engages with a corresponding female screw-thread in the lowerend of the tube f. The lower end of the rodi' bears upon the top ofthe mold J, and it is provided with ahand-wheel, i, at its upper end, by which it may beturned. Two bolts, kk, are secured at their up per ends in the upper end ofthe cylindrical socket I, and, passing through holes in the rubber ring 71 disk e, and mold J, are provided with nuts l Z at their lower ends, the purpose of said bolts and nuts being to preventthe mold J from dropping down and resting upon the edge of the wheel H. The upward pressure of the mold J', taken upon the end of the screw i, is transmitted by the disk e to the rubber ring 71, compressing it against the upper end of the socket. I. The pressure of the mold J upon the work being formed may be regulated by the nut g by turning said nut so as to raise the disk e and compress the rubber l1y when greater pressure is wanted, or by turning the nut in the opposite direction so as to lower the disk e and allow the rubber to expand when a less amount of pressure is required, while the mold .I is adjusted toward or from the wheel H by means of the screw i and nuts Z Y.

The mold E,before referred to,is held in a cylindrical socket, L, provided with a shank, m.,

' and nut n, for securing it within the slot o of the frame A. The socket L is provided with mechanism for adjusting the mold E and regulating the pressure thereon, constructed precisely similar to that above described in connection with the socket I, except that the bolts 7c 7c are dispensed with, as the axis of the socket L is horizontal, and the mold E has no tendency to slip from its place. Two pins, p p, (shown in Fig. 1,) project from the edge of the mold E upon opposite sides of the shaft (l, and serve to prevent the mold E from turning round in the socket L.

In the operation of my invention a blank is iirst fed endwise between th e former D and mold E, or by modifying the shape of the mold and former the blank may be fed between them transversely of its length, by which means it hasaY curved shape imparted thereto in two directions. It is now desired to reshape the counter-stiffener to make it conform more nearly to the shape of the last upon which the boot or shoe is made by giving the counterstiffeners a sharper bend at the back of the heel and bringing the sides nearer together.

This is done by passing the counter between the edge 'of the wheel H and the mold J in a direction at right angles to the length of said counter-stiifeners, or transversely thereof, so that the counter-stiifeners will be compressed between the edge of the wheel H and the mold J at the back of the heel for a width about equal to the thickness of the wheel H, while the sides ofthe coiniter-stiifeners will be pressed inward by the action of the mold J to form what I term a reshaped unflangedy counter,77 substantially as shown and described by me in another appli cation of even date' herewith. In reshaping a counter-stiffener having a fiange around its lower edge, I make the wheel H,as shown in Figs. 5 and 6, with two lugs, s s, pro! jecting from opposite sides of said wheel, and a radial slot, r, in its edge cutting through said lugs. A former and mold of suitable shape for making aflanged counter-stiffener being substituted for the former D and mold E, the blank is passed endwise between the said former and mold, which compress and crimp it toform a circular flanged counter-stifiener ready for rey shaping. It is then placed upon the wheel H. in the position shown in dotted lines in Fig. 5, with a portion of its iiange at the back of the heel inserted in the slot r, when the rotation of the wheel H will carry the counter through the inold J, compressing and shaping itin the same manner as in the case of the unflanged counter-stiffeners, as above described, the p ortions of the flange at the side of the counterstiffeners being supported by the walls of the slot r as the said sides are pressed inward, said walls thus preventing -the counter-stiifeners flange from being disturbed or thrown out of shape. Y

By the use of my present invention I am enabled to reshape counter-stiffeners in a very simple and effective manner, as by firmly com- 4pressing them at the back of the heel in the ters are shaped by being pressed around a form corresponding in shape and size to thelast upon which the shoe is to be made. By the arrangement of the cylindrical sockets I and L andY mechanism contained therein, avery simple and convenient means of adjusting the molds E and J is obtained, while the method of attaching the sockets I and L to the frame A permits of their removal for the purpose of changing their respective molds.

The width and shape of the nished counterstiffeners may be varied by changing the width of the wheel H and the width and shape of the concave working-suri'aee of the mold J.

W'hat I claim as new, and desire to secure by Letters Patent of the United States, is as follows:
