HEEL-STIFFENER MACHINE.

SPECIFICATION forming part of Letters Patent No. 447,944, dated March 10, 1891.

Application filed October 2'7, 1890. Serial No. 369.423. (No model.) i

T0 at whom it may concern:

Be it known that I, LOUIS COTE, of St. Hyacinthe, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Heel-stiffener Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to machines for forming heel-stifieners, and is an improvement upon the machine described in Letters Patent No. 435,481, granted to me September 2, 1890; and it consists of certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings, and to the claims hereinafter given, and in which my invention is clearly pointed out.

Figure 1 of the drawings is a front elevation of so much of a machine as is necessary Fig. 2 is a side elevation of the same. Fig. 3 is a plan of the mechanism for reshaping the side portions of the stiffener and turning the flange on said stiffener. Fig. 4 is a front elevation of a portion of the same parts. Fig. 5 is a vertical section on line 1 l on Fig. 3. Fig. 6 is a sectional plan of same parts with the two parts of the divided former in contact for the greater part of their lengths, the cutting-plane being on line 2 2 on Figs. 4 and 5. Fig.7 is a simi-' lar sectional plan with the free ends of the divided former separated and pressing the side portions of the stifiener between it and the molds, and the reciprocating notched plate moved into the position to turn the rear portion of the flange. Figs. 8 and 9 are respectively a side elevation and an inverted plan of the divided former. Fig. 10'is an elevation of the inner or working face of one of the molds which co-operate with the divided former to reshape the sides of the counterstiffener, and Fig. 11 is a central vertical section of the notched plate for turning the rear portion of the flange. In the drawings, Ais the frame of the head of the machine, constructed and arranged to be supported upon a column B, only a small portion of the upper end of which is shown, said frame having mounted in suitable bearings formed thereon the horizontal shafts G, D, E, and F. 4

G and G are the tight and loose pulleys on the driving-shaft O.

a, b, c, and m are gear-wheels connecting said shafts.

g and g are fluted rolls for corrugating that portion of the blank from which the flange or heel-seat of the stiffener is to be formed.

H and H are respectively the former and mold for performing the second operation upon the blank of imparting thereto curves both longitudinally and transversely. I and J are respectively a revoluble disk and an adjustable mold for performing the third operation, or the reshaping of the center or rear portion of the partially-formed or clam-shell counter-stiifener.-

So far the several parts of the machine are constructed, arranged, and operated substantially as in my before-cited patent.

In the machine described in my beforecited patent the table L was securely bolted to the frame A and had formed in its upper surface a transverse groove, in which were fitted two sliding plates, upon which were pivoted two molds to co-operate with a divided former pivoted to the table L, to reshape the side portions of the stiffener without attempting to turn the flange.

In my present invention I form the molds O 0 with'the inwardly-projecting lips e a, which extend along those portions of their lengths which act upon the side portions of the partially-formed counter to reshape the same, said lips 6 extending under the two parts of the divided former P, each of which is provided with the lip or rib f, extending along its bottom surface, saidribs f'being of a vertical height equal to the width of the flange to be turned on the counter-stiffener and serve to raise the main body of the former above the surface of the table a sufficient distance to permit the lips e of the molds O to pass beneath the body of said former, carrying therewith those portions of the blank which are to form the flanges of the sides of the counter-stiffener.

The two parts of the former P are pivoted together and to the table L, and the molds O O are pivoted to the sliding plates M in sub. stantially the same manner as in my beforecited prior patent.

In my prior patent the slides M were face of said table into the said bore to receive said slides, as shown. The outer ends of said bore are closed by the screw-plugs N N, and between the inner ends of said plugs and the outer ends of the pistons N N are placed circular disks of'thick rubber Q, which serve as springs to press said pistons, their attached slides, and the molds O Otoward each other.

The ribs fon the under side of the two parts of the former P extend toward the heel end of the former only to the outer side of the pivotal pin about which said parts move, so that the rear portion of the lower edge of the counter may be turned under said former to form the flange or heel-seat around the heel end of the counter-stifiener.

The front end of the table L has formed therein the open slot h, in which is fitted, so as to be movable toward and from the front of said table therein, the block or arm R, upon the upper end of which is firmly secured the plate S, the inner edge of which has formed therein the curved notchz'and recess j, fitted to conform substantially to the under side of that portion of the former under which the blank is to be turned to form a flange around the heel end of the stiffener.

The lower end of the arm R is fitted upon the rod T by a sliding fit and is arranged to be locked to said rod by means of the latch-lever 7c, pivoted to said arm at 7t and arranged to engage with the notch Z, formed in said rod T, at the pleasure of the operator. This is accomplished by means of the link or rod m, pivoted at its upper end to the free or movable end of the latch-lever is and at its lower end to a treadle,(notshown,) said latch-lever, rod, and treadle being raised to disengage said latch-lever from the notch Z by the spring 02, all as shown in Figs. 1 and 2.

The rod T has formed in one piece therewith the yoke T, in which is formed the slot 0, extending at right angles to the axis of said bar, with which slot the crank-pin 19, set in the disk U, operates to impart to-said rod a reciprocating motion at each revolution of the shaft V,upon which the disk U is mounted.

The shaft V is mounted in suitable bearings in the frame A and has secured thereon the spur gear-wheel WV, the teeth of which engage with and are act-ed upon by the teeth of the gear on to impart to said shaft V a rotary motion.

X is the cam for moving the free ends of the two parts of the divided formeraway from each other, and Y is the spring for moving said parts toward each other and toward the cam, arranged to operate substantially as in my prior patent before cited.

The operation of my improvement is as follows: The parts being in the positions shown in Figs. 1, 2, and 3 and the driving-belt being shipped upon the tight pulley, so as to set the machine in motion, the blank is subjected to the first three operations by passing it endwise between the fluted rolls g then between the former H and mold H and then transversely between the edge of the disk I and the mold J to reshape the center or heel portion of the partially-formed counter-stiffener. The counter-stiffener is then slipped endwise upon the heel end of the former with its sides between said former and the molds O and its base edge resting on the table and its heel end between said former and the flange-turning plate S, where it is held until its sides have been subjected to a suitable number of blows in succession to properly reshape the upright portions of the sides and turn under said former the side portions of the flange or heel-seat, and then the latch-lever 7c is pressed down so as to engage with the notch Z of the rod T, when the plate S will be moved forward beneath the heel end of the former and the front ends of the molds O, as shown in Fig. 7, thus turning the flange of the heel and of the counterstiffener and completing the shaping of the same. By the use of myinvent-ion counter-stiffeners of any style or size can be made upon a single machine and have their flanges turned so that they are ready for use in boots or shoes and require very little care or labor of the operator in applying them.

I claim 1. In a machine for shaping counter-stiffeners for boots or shoes, the combination of a former approximating to the shape of the heel portion of a last and provided along the center of its tread-surface with a downwardlyprojecting rib, leaving a recess on each side, a pair of molds having their inner faces made to conform to the shape of the sides of said former and each provided with a lip to overlap or pass beneath a portion of the treadsurface of said former, arranged one upon each side of said former and to be moved toward and from each other and said former, and a notched plate constructed and arranged to be reciprocated in the direction of the length of said former to turn the rear or heel portion of the flange of the stiffener, While the side portions of said flange are turned by the lips on the molds.

2. In a machine for shaping counter-stiffeners for boots or shoes, the combination of a former made in two parts pivoted together and to the table or bed of the machine at or near the center of the heel end and provided with a downwardly-projecting rib extending from its pivotal connection toward its free or movable end, a pair of molds arranged one upon each side of said former and mounted upon movable pivots, with their inner faces made to conform to the forward side portions of said former and each provided with a lip to project under the tread-surface of said former to turn the side portions of the flange of the stilfener, springs for pressing said molds toward the former, a reciprocating notched plate for turning the rear portion of the flange of the stiffener, a revolving wedge-like cam constructed and arranged toact upon the free or movable ends of the two parts of said former to separate them, and a spring to move said part-s toward each other and said cam.
