IMPROVEMENTIN BLANKS FOR SHOE-PEGS.

Specification forming part of Letters Patent No. 25,149, dated August 16, 1859; Reissue No. 2,286, dated June 12, 1866.

'or ribbon of wood. Fig. 2 is a side elevation of the same and Fig. 3 is a section through the same.

Prior to the date of my invention machines for pegging shoes came into actual use, and it was a desideratum to discover for employment in them a better peg-blank than had been hitherto manufactured. These blanks, both for hand and machine use, had, prior to my inven tion, been made by splitting or sawing strips of the thickness of the length of a peg and as Wide as a peg from a slab of Wood cut across the grain of a log. When these strips were split they had not that uniformity of size desirable for use in a pegging-machine; when sawed there was a waste of material, and in both instances the strips were being limited in length by the diameter of the log, being too short for profitable use and too expensive,

After some consideration and experiment I discovered a means of making shoe-peg blanks by which I was enabled to make my new article of manufacture. This machinery consists of an ordinary lathe with a slide-rest hating a feed motion which will carry it regularly toward the axis of the lathe-spindle or across the ways of the lathe. On the restis secured a knife with one side of the edge beveled, and

- with the beveled side farthest from the axis of the spindle, and With the edge parallel to that axis. There is also secured to the rest a guard which bears upon any wood that may be in the lathe in advance of the knife-edge, and also makes pressure upon the wood that has been cut by the knife griping it. Aknife or knives so arranged as to eutinto the wood between the guard and the knife in planes perpendicular to the lathe-spindle axis, and also attached to the rest, andthese knives score the log before the first-described knife cuts it, and if more than one be used theyl are set apart from each other at distances equal to the lengt-h of a shoe-peg. By the use of these means a spiral of Wood can be cut off a log` of wood, previously turned cylindrical, of the width of the length of a shoe-peg, as thick as the thickness of a peg, and of a length depending upon the diameter of the log and the thickness of the scroll or spiral. Such strips are uniform throughout in width and thickness, and I have made them from iifty to sixty feet in length. After the strips are thus cut they are to beso shaped on one edge that when split the pegs produced will be pointed. I prefer to shape the edge by means of knives in circular cutters, similar in construction and use to those used in molding or stave-jointing machines, to shape the edge, as shown in the drawing; but the precise conguration of the edge from which the point is to be formed is immaterial, so long as it is of such character that the pegs when split from it are pointed sufficiently for the purpose of driving them into soles.

This is the way in which I prefer to make these peg-blanks; and in order to have these distinguishing characteristics they must be cut with their length in the direction ofthe spiral or scroll around the center of the log, or nearly so, and their distinguishing characteristics, when finished, are, irst, that they are as wide as the length of a peg; second, that they are as thick as the thickness of a peg; third, that they are on one edge so shaped, substantially as shown in the drawings, as to fit pegs split from them for being driven by the action of some proper instrumentality; fourth, that they are so shaped on the other edge, substantially as represen ted in the drawings, that pegs split from them shall be properly pointed, so as to be tit for driving into soles; fth, that the strip or scroll in the direction of its length is composed of bers of wood that originally run round the log continuously, substantially in the direction of a spiral or scroll, and that lines drawn perpendicularly across the strip or finished manufactured articles will cross the iibers in the direction of radii extending from the center ofthe log from which the strips are cut, or substantial-l ly so.

" the utility .aid of the foregoing The new article of manufacture herein described, Which is a peg-blank having essential characteristics, substantiallysuch as herein set I do not think it necessary to enlarge upon of the article of manufacture herein described, to show manufacturers or pegblank makers, to whom this specication is forth.
