CaiMPlNG-BOARD Foa BooTs AND SHOES.

SPECIFICATION forming part of Letters Batent No. 251,568, dated December 27, 1881.

Application tiled October 5, 1881.

To all whom fit may concern:

Be it known that I, GHAnLEs It. GIBBs, a citizen of the United States, residing at Harrisonburg, in the county of Rockingham and State of Virginia, have invented new and useful Improvements in Crimping-Boards for Boots and Shoes, of which the following is a specication.

rI his invention relates to an improvement in the crimping-board for boots and shoes secured to myself and E. Feddon by Letters Patent ot the United States dated May 3, 1881, and numbered 240,996. The crimping-board madein accordance with the invention secured by said Letters Patentconsisted of a vertical leg or body portion, formed integral with a foot portion, having side curves to impart the right and left formation of the footto the leather, and an upper curve for imparting the instep formation to the same. In manufacturing these crimping-boards they have been cut from a solid timber, and as the leg or vertical body portion is considerably longer than the foot portion the crimping board has been formed with the grain running lengthwise with the said vertical and longer portion, both for the sake of economy in material and also for rendering the body portion strong and durable; but this mode of manufacturing the crimping-board necessarily produces a foot portion with the grain of the wood running transversely' to its length, since the foot portion is at, or about at, right angles to the vertical or leg portion ot' the article through which the grain runs longitudinally. Hence the foot portion possesses less strength and durability than the body portion, and is liable in time to be broken oft' or chipped, so as to render it unfit for further use. If, however, such crimpingboard were cut out ofa single piece of wood, with the grain running lengthwise ofthe foot portion, the latter would be strengthened at the expense of the body portion, the grain of which latter partl would then necessarily run transversely to its length.

It is the object of my present invention to obviate such defects by so forming the crimp ing-board that the grain of wood shall run longitudinally both with thelength ot' the vertical (No model.)

runninglengthwiseorlongitudinally with each, and then secure said two parts firmly together, in order to form the complete cri mpin g-board.

The construction ot' my improved crimpingboard is represented in the accompanying drawings, in which- Figure 1 is a perspective view with the upl per and leg portion of the leather in position and crimped. Fig. 2 is perspective view ofthe complete crimping-board. Fig. 3 is a bottom view; and Fig. ,4 represents a section through one of the clamps for drawing and holding the leather upon the crimping-board, the latter being also shown in section. Fig. 5 is a crosssection on the line m fr of Fig. 1. Fig. 6 is a side elevation, partly in section.

The letter A indicates the vertical body or leg portion, which is shaped along its length to crimp the leg of the boot, and formed with the grain a, running longitudinally or substantially parallel with its length.

The letter B indicates the footportion, which is shaped with the curved portion C, for crirnp ing or forming the instep to the leather, and with the opposite curved sides D E, for causing the upper to partake of the right and left sides of' the foot. This footportion is made separately from the leg or body portion, and is formed with the grain c, running longitudinally or substantially parallel to its length. The

lower end of the leg or body portion and the upper portion, c', consisting of a short neck of the foot, are formed so as to tit closely together, and arerigidl y secured by any/suitable meanssuch,forexample, as by dowel-pins on one part entering recesses in the other part. In this way a strong crimping-board having not only all ofthe characteristics of' that secured by said Letters Patentis produced, but also one having the grain of the wood running longitudinally both with the leg or body and with the foot portion ofthe same.

The letter F indicates the recesses formed in the body and foot portions for receiving the clamp-rods and nuts; and G indicates one ot' the clamps employed for holding the leather upon the crimping-board, said clamp comprising the screwthreaded bolt G, with the nutg, fitted thereon, and the angle-plate H, formed with serrated ri gid jaws for holding the leather, and arranged loosely upon the screw-rod back ofthe nut. This clamp will be applied as illustrated in Fig. 4 of the drawings, in which it will be seen that one end of the rod is stepped in a small socket, h, at the bottom of the recess F, and the nut upon the screw-rod received in the said recess F. The leather is clamped at its edges between the ronghened beveled sides of the nut and the inner serrated sides of the angle-plate, which said sides are inclined, so as to conform to the bevels ot' the nut. By now turning the rod in the socket receiving its end the nut will recede from the crimping board, and hence stretch the leather, which, in the first instance, will be firmly clamped between the nut and jaws ot' the angle-plate by holding the latter and turning the screw-rod.

Having thus described my invention, what I claim is- As al1 improved article of manufacture, the

herein-described crimpin g-board, consisting of 2o two parts permanently secured together, one of said parts being the Wooden vertical body portion A having the grain runninglongitudinally to its length, and the remaining wooden foot portion B having the grain running longitudinally to its length, and having the side curves, D and E, to impart the right and left formation of the foot to the leather, and the curve C, fol-imparting the instep formation to the same, substantially as described.

In testimony whereof I have h eunto set my hand in the presence of two suL cribing wit-
