SPECIFICATION forming part of Iietters Patent No. 291,017, dated January 1, l84.

' Application filed May 7, 1883. (No model To @ZZ who/1t it may concern:

Be it known that I, HIRAM R. ADAMs, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Ap- 5 paratus for Crimping Boots and Shoes, of f 'which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. n, .Boot and shoe uppers arenow usually crimped by placing the same in a crimping-machine, where they are engaged by a form and forced between jaws which stretch and fit the upper to the form as the latter is forced between and below the jaws. In this common method of crimping, the entire crimp imparted to the upper is given to it by one continuous passage of the upper acted upon by the form between the jaws, and the movement of the parts being rapid itis found impracticable to give to the upper but a limited amount of curve, and even with but little curve the uppers are frequently torn and injured, and the operation being quickly performed the leather has no 5 chance to set, and much of the stretch put into it while being passed between the jaws is lost as soon as the upper leaves the jaws. In accordance with my invention I have pivoted the foot of the crimping-form to the leg, so that when the edges of the upper are attached to the said foot and leg in their nearly straight condition the relative positions of the foot and leg are changed, gradually forcing the foot into a position more and more nearly to a right angle to the front of the leg part of the form, the said leg part being of greater or less length. During the forcing ofthe foot into its eect- `ive position,77 as I shall call it, the upper is acted upon by a `suitable rubbing device-Aa `wheel or stick in thehands of or controlled by an operator+-and the upper is thus gradually l crimped andthewrinkles,rubbed down and "but: giving ELDlllvlulent lshape'aud set to the J leather.4 f w. s

f `In my inverni-.mayasherein embodied, the

n uppermaybe lasted andat the same time be crimped, so that it may be applied directly to a last having a suitable inner sole, and the 1 flanged or turned-over edges of the upper will 5o be in proper stretched and bent condition to be united with the soles, the soles being united by staples, as in my Patent No. 262, 552, or by any other usual fasteners. My invention consists, essentially, inabootcrimping form composed of a leg and a foot 5 5 pivoted thereon, and adapted to be turned the one with relation to the other and both upon a common pivot, as will be described, to gradually effect the crimping operation, also, in a pivoted crimping-form having a pivoted 6o foot, combined with means to change the relative position of the said foot and leg to gradually effect the crimping operation.

Figure l is a longitudinal sectional view of a boot-crimping apparatus embodying my invention; Fig. 2, a rear side or edge view of the leg and foot removed from the leg-holder, and Fig. 3 a detail showing part of the soleplate of the foot with upper engaging orholding devices thereon.

The'foot A, preferably made last-shaped and as a cast-metal shell, is connected with the leg part B, also preferably made hollow and of cast metal, bya pivot-pin, C, or'other suitable hingej oint, care being taken to avoid as much as possible seams or spaces at the junction of the foot and leg to keep the leather smooth at that point. The leg part is attached to the leg-holder D by suitable screws or bolts, a, the said leg-holder having an ear, b', boredto fit 8o the guide-rod b2, to which it is rigidly attached, the said rod being placed loosely insuitable lugs or brackets, b 1f, bolted to abcd or bench, E, by bolts d. The rod bZ serves asV a guide for a yloose collar, e', having pivoted upon it one linke2, of a toggle-jointed lever, e? e3, the member e being pivoted on the ear b3. The central pivot, c5, is connected with ablock, e, having attached to it a rod, 5*, which will be operated by a treadle so pivoted that the pressure of the foot on the treadle will move the rod e4 in the direction of the arrow thereon, and cause the collar e to force the head or cam block f in the direction of the arrow on it, so that the said block placed loosely on the rod b", and acting on the extension g ofthe foot, will turn it gradually from its dotted to its full line position. The leg has flanges h, extended down into the foot below the pivot C, and slotted, as shown at h2 in Fig. l, to receive rods ha, having on them at the sides of the flanges suitable collars, h The bottom of the foot will be provided with a series of upper holders or clamps, B, substantially as shown in another application filed by me, wherein the same letter is used. The upper will have its edges clamped to the foot and leg, while the foot is in its dotted-line position, and then the toggle-lever will be gradually moved from its dotted to its full line or effective position, bringing the foot into its full-line position; and during this operation the operator will rub the upper on the foot and at the junction of the foot and leg, gradually iitting the upper to the foot and leg as their relative positions arechauged. During the operation the operator will rock the leg-holder I) and form, so as to place iirst one and then the other side of the form uppermost or in the most handy position to rub the upper, and during this time the block j" is also rocked ou the rod b in unison with the form.

I do not limit myself to the exact upperholding devices shown, and instead of them I may use any other suitable holding devices, or may engage the edges of the upper with pins yn, on the leg and foot. I do not desire to l. A boot-crimping I'orm adapted to be turned laterally upon a longitudinal pivot and having its foot portion pivoted to the leg portion, combined with means, substantially as described, to gradually force the foot portion more and more nearly into a position at right angles to the leg portion to crimp the upper, as set forth.

2. In a crimping apparatus, a leg portion and a foot portion pivotcd thereto, combined with a rod, If, on which said leg portion has a lateral rocking movement, and a block movable longitudinally of said rod and engaging the foot portion to force it into a position more or less at right angles to the leg portion, substantially as described.

3. In a crimping apparatus, the leg and pivotcd foot and leg-holder and the rod or guide to pivot the leg-holder, combined with means to automatically operate the foot, as described, while the crimping-'form is free to be rocked or turned with the said rod, substant-ially as described.

In testimony whereofl have signed my name to this speciiication in the presence of two subscribing witnesses.

IURAM R. ADAMS.
