gni-tris tang gntrnt @time HENRY WRIGHT, OF SACO, ASSIGNOR- TO JAMES R.. CLARK, OF BIDDE FORD, MAINE. t

Letters Patent No. 73,483, dated January 21, 1868.

IMPROVED; Boor-omar.

TO ALL WHOM ILT MAY CONCERN:

Be it-known that I, HNRY WRIGHT, of Saco, in the county of York, and State of Maine, have invented certain new and usefullmprovements in Boot-Crimps; and v:l: do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, und the letters of reference marked thereon.

The nature of my invention consists in certain iinprovements in the eonstructionland arrangement of the details 0f a hoot-crimp, said improvements being'of such nature as not to admit of being briefly set forth.

, Drawings.

Figure 1 is a perspective view of my hoot-crimp in working condition.

Figure 2 is an elevation of the crimp.

Figure 3 is an elevation, with the stretcherf removed.

Figure 4 represents the stretching-device.

Figure 5 is a section of the lever.

Figure 6 is a. section through the'line x y, iig. 2.

c A, gs. 1, 2, 3, and 6, is the form, such as is used by all boot-makers, made of suitable material, and of such dimensions as .is desirable. To this form is attached the incline-bar B, gs. 4, 5, and 6, made of suitable metal, having the inclined planes b m cast thereon. To this bar is attached a straining-bal', D, which oneloses the har B on three sides, and is held to by the screw H', iigs. 1, 4, and 5. Said screw H works in a slot in D, as shown in tig. 1, so that the incline-bar B may have a longitudinal motion with the straining-bur D. a, figs. 4`and 2, represents a short straininghnr, attached to incline-bar B by the screw H, inthe saine manner that the bar D is attached. B', tigsf2, 4, andA 5, represents' an enlarged part of the incline-bar B, and forms what may be called the head of the crimp. The socket R, iig. 5, receives adowel, L, whichv is permanently attached to the lower straining-bar E. The straining-bar E terminates in a thin flexible metallic strip, E', which, being made fast tothe form A, serves asa flexible and yet quite rigid connection. S,gs. 1 and 2, is u. bolt passing through a projection on the straining-bar D, and downward into the form A, to which its lower end is'attached by means of the screw K, ns shown in iig. 2. The upper endet' the rod S is provided with a nut, so that the strniningbar D cannot move up or dawn, but may swing out from the form, as shown in g. 2.

The incline-bar B`has permanently attached to it two inclines, B and M, which work in corresponding inclined sockets made in the form A. The lower incline, M, is provided with a dove-tail, m', figs. 4 and 5. This dovetail serves to keep the lower end of the incline-bar in position. J, figs. 2, 4, and 5, is a. thumb-screw which works through the straining-bar D, andis attached to the incline-bnr B by a swivel, w, fig. 5. This thumb-screw serves to move the incline-bnr B, and by it all the straining-parts ofthe crimp. O O, Stic., are small dogs, used for attaching the vamp to the crimp. The method of using my crimp is so obvious to those skilled in the art as to require no explanation.

What I claim V:is my invention, and desire to secure by Letters Patent, is

, 1. The combination and arrangement ofthe screw-bolt S,the 4straining-bar D, the screw H', and the inclinebnrB, allmade substantially as and for the purposes set forth.

2. The combination of the dove-tail vM', with the incline M, substantially as described and for the purpose set forth. I l

3. The lexiblemetallic connection E', in combination with the lower straining-bar El i i HENRY WRIGHT.
