Leners Patent No. 90,477, dazed Maly 25,1869.

IMPROVE!) BOOT-GRIMPER.

The Schedule referred to in these Letters Patent and'making part of the same.

To all whom 'it may concern Be it known that I, J OHN B. AIKIN, of Somerton, in the county of Belmont, and State of Ohio, have invented a new and improved Boot-Grimper; and I -do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part 'of this specification, in which- Figure l is an end elevation,

Figure 2, a side elevation, and

Figure 3, a detached view ot' a part of the olimping-board, or pattern, showing a portion thereof 1n section.

The object of this invention is to provide for public use a boot-crimper, which can be very quickly and conveniently operated, and which will crimp the boot without wrinkling the leather at the instep.

In the drawiugs-'- A represents the frame of the machine, which resembles that of an old-fashioned hand printingpress, being supported on three legs aa a,and having a stout standard, a?, the object of which is to support the plate B, which forms the tixed jaw of the clamp.

B is the movable jaw of the clamp, it being supported on a standard, b, which embraces and slides horizontally upon an armor shank of the leg al.

G is a screw-rod,l working through a nut, c, for the purpose of moving the jaw B hackand forth, toward and from its companion B.

D is a spring-standard, supporting the rod G, and forming an abutment which confines the -nut c in place,- and insures. the properv operation vof the Yscrew-rod, while, at the-same time, it yields slightly, allowing the movable jaw to give7 as the pattern and boot are forced down between the clamps.

M is the pattern, or crimping-board, having a piu, fm, at one end, and a ratchet-plate, m', at the other, as shown in iig. l. i

N is a sti" rod, constructed to fit to the inner edge Aof the crimping-board, and to press a smoothing-plate,

O, against it at the instep of the boot, as shown in fi 3.

The plate O is bent to conform to the angle of the instep, and is articulated to the rod N, as shown at o. It lits like an inverted saddle over the edge of the crimping-board, extending up a short distance on each side, and operating, when pressed in place, to coniine the leather firmly to-the board, and prevent its slipping and wrinkliug as the board and boot are forced between the clamps.

The rod N is fixed in place by fastening one end oi' it over the pin, or hook m, bringing the plate O into position, forcing the opposite end of the rod almost against the edge of the crimping-board, and conining it there bymeans of a hook, P, articulated to the end of the rod, and engaging with the ratchet-teeth, as shown in iig. 1.

F is a vertical rack-slide, working in a suitable socket, or bed in the frame A, or standard a2, and capable of being moved up and down by means of a pinion, f.

- G gis a gear-arrangement, for the purpose Vof increasing the power, and

g is the crank by which the operator applies the power to move the slide. l

f' is an arm projecting out horizontally from the slide F, and serving to support a stout bent rod, or arm, J, by means of which the pattern and boot can be forced down between the clamps.

In operation, the leather is properly cut and tacked to the board M, and is stretched or drawn up at the instep by means of the screw I and corrugated clamp, or nut I'.

The jaws B B are then slightly separated andthe board placed betweenthem, as shown in figs. l and 2, and forced down a short distance by hand.

The operator then takes hold of crank g', turns it to the left, and runs the slide F and rod J up sailiciently far to allow the bent end of the rod to be brought over the apex of the pattern, and inserted into a socket, c, as shown in fg.,3.

The jaw B is then screwed upsuiiciently, andthe 4 crank g is turned to the right, which runs the slide 'and bent rod J down, forcing the crimping-board and boot down between the two clamps B B', and thoroughly crimping the leather, without tearing or wrinkling it.A i

As the board is thus forced down, it operates like a vwedge between the two clamps, its lower edge being made tapering, or wedge-form, as shown in fig. 2, to adapt it to that purpose, and it presses back the movable jaw, orclamp B', the spring yielding to accommodate the latter, but yet holding it firmly against the crimping-board and leather.

When it is desired to raise the crimping-board, or pattern out from between the clamps, the latter are separatedby means of the screw-nut o, and the crank g is turned to the left. This raises the bent rod J, and as it rises', its notched point, engaging with a stop, t, draws up the crimping-board from between the clamps. As soon as it is clear of' them, the operator, pressing his iiirger o the stop t, disengages it from the rod J, and removes the crimping-board.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The bent rod N, having the part 0 articulated to it, as shown at o, and adapted to be attached to the-crimpiug-board byl means of the pin fm, rack m', and hook P, substantially as and for the purposes set forth.

crank g, -the bentrod .L 'having the notch at its upper end, and'dtpted to operate in connection with the stop t, attached to the crimping-board, substantially as and for the purposes specified;

3. The combination of the spring-standard I) with the nut c, screw-rod O, and movable jaw B',vwhe`n 2.111 eombinaton with slide F, wheels Gr y, andemloyed in a, boot-ol'imper, substantially as' and for the pnrposes set forth.

To the ztbove speeica tion of my invention, I have signed my hand, this 17th day of Api'il, 18.69.
