REUBEN FAIRCHILD AND STARR FAIBCHILD, OF TRUMBULL, CONEGTICUT.

BOOT-CRIME.

Specication of Letters Patent No. 4,038, dated May 10, 1845.

To all whom t may concern .Be it knownthat we, REUBEN Famer-ULD and STARR FAIRCHILD, of Trumbull, in the county of Fairfield and State of Connecticut, have invented `a new and useful lmprovement in the Mode and Combination of Apparatuses for Crimping Boots; and we "1 do hereby declare that the following is a i any common boot crimp, in whatever way they are or may be hereafter constructed or any part thereof, which prevents the leather when placedbetween them from wrinkling and forming an uneven surface in crimping, and making a more durable and strong crimp; when thus placed together, a bar is extended over the crimp, with crank screws hanging in or being screwed through said bar, or screws being inserted into the heel or back of the form, with a nut attached to attach a hook and eye thereon, which serves to draw theA leather into the form required, said hook and eyes may in certain cases be projected over on the back of the form and when secured together hold the leather from giving back, and may be rubbed off by hand or it may be forced through between two cheek pieces and stretched into form and made smooth, where it is held by the arrangement and combination of said hooks, therewith in some instances without nailing, as hereafter more fully described, and detached from under the jaws.

The construction is as follows, Figure l, shows the jointed crimp, it is composed of several strips of wood, iron, or other suitable material, which are placed side byside each other and tongueand groove, together, with dovetails groove and tongue; so that they t can slide one upon therother, the innerV strip (a) has a segment joint as shown atA. d etached, so as to present an 'even surface 1n all positions opposite the above named oint, all the other strips are jointed as at (22),the inner strip has a hook (c) at one end that is hooked into a staple in the bar (d), when the crimp is in the position shown by the red lines, the outside strip has a handle (e) aiiixed to theend opposite the hook on the `inner strip, by which it is borne down and all the joints bent as represented in the figure, (or it may be otherwise bent in form), the rounding edge of the inner strip being forced upon the bar (d), the leather is stretched somewhat into the desired shape, or in some instances it may be completed on this instrument, a whalebone or other elastic material may be substituted `for the inner strip (a).

Fig.` 3, is a machine for perfecting the crimp, and is made as follows: A frame (a) is formed consisting of two upright posts framed into arbase, with a groove cut on theinside of each post for a guard to slide in; near the top of said post are two jaw pieces that extend from one post to the other, von each side of the above named groove and just far enough apa-rt to have the guard leather Sec., slide between them.

These jaws have a triangular projection on i their upper side, and their `distance apart is regulated by set screws (c) in each post, on one side of the guard there a shaft (d) below the jaw bearing a pinion near each end, these work into corresponding racks (e) on the guard, and outside the post on one side there is on the same shaft a spur wheel (f), that gears into a pinion (g) on a crank shaft, which when turned causes the gate to move up and down; the bar is not permanently connected with the guard and does not pass down through the jaws but rests on the posts above as shown in F ig. `(3), but it rests on the side pieces (c), of the guard when raised up to receive the leather above the jaws, as shown by the dotted lines. j

The guard for passing through the above jaws may be composed of two side pieces in which the racks (e) are situated, with a cross piece (h.) near the same shape on the upper side as the outline of the crimped leather when perfected, and corresponds with the front of the former (0), having a groove in its upper edge to act as a guard (76) passing throughit that serve to draw the hooks, that the leather is attached to, up till they are brought over the edge of the former (o), when they are connected and hold the leather while the screw is detached. One of these hooks is shown detached in F ig. il, it is a flat plate with an eye in one end, and the other curled up so as to receive the leather into it, and be fastened by a pin which is slipped into the.

hook. This guard is forced down by the crank or by any other plan that suits the construction and operation, the leather having been placed between the former and guard which protects its edge while being acted on by the screws and jaws between which it is clamped, when it has passed down below the former with the leather attached as shown in Fig. 5, is detached from the guard and laid away to dry. We also have discovered what might be called a variety of forms or shapes for crimping boots, which may be shown by taking hold cfa piece of leather when crimped in its usual form and bringing it in a straight position with the crimped part, or bending it so the ends or leg and foot are brought together or nearly s0,) and forms may be made in any shape that the leather may form in undergoing this operation, or by slightly pressing it by hand to form any shape you desire, which crimps the leg o-n one side of the form and the foot on the other in same instances; as shown in Fig. 6, detached from the guard and jaws; (B) is the foot crimped on one side of the former (O), the dotted line (L) is the outline of the leather on the opposite side. The guard may be applied on the edge of crimped, the leather being placed between Y them, to prevent wrinkles, &c., as herein described.

3. We also claim the hooks Fig. 4:,/in combination with the screw vand nut, and connected to the leather, so as to be brought over the back of the former and passed through between the jaws as set forth.

4:. lVe also claim in combination with the above named guard and form the bar in which the screws for drawing back the leather are situated, in the manner, and for the purpose before specified.

5. Also the passing of the form and leather down through the jaw piece, as herein set forth, with, or without a guard on the edge of the former.

6. XVe also claim the variety of ways for constructing forms as herein made known, in combination with the guard.

7. Also the application of cranks to screws, and'used in crimping boots as herein before mentioned. Y
