SPECIFICATION forming part of Letters Patent No. 287,282, dated October 23, 1883. Application filed September 1883. (No model.)

My invention relates to wooden hames braced or bound by iron stays or ribs, the object being to provide an iron binding made in a single piece having the required strength, combined with lightness, and capable of being formed in roller-dies, whereby the cost of production is materially diminished.

Heretofore in the manufacture of hames it has been necessary to make the iron stay in two separate pieces, which are welded together by hand, one of said pieces being of such thickness as to impart the required strength to the bowed end of the hame,which supports nearly all the strain, while the other is made thinner,

in order to give such degree of strength as is facture is largely increased.

necessary, and at the same time avoid undue weight and clumsiness. This method of making the iron stays has given rise to several serious objections. It has been found practically impossible to form them by rolling and in a single piece, and, owing to the necessity of shaping each part separately and then welding them by hand, the expense of manu- Moreover, it is evident that the welding must be done with the greatest care in order to effect a perfect union between the two parts, and even when all possible pains are taken it frequently happens that a little wear and some oxidation of the metal will open seams or cavities between the parts which were not perfectly united during the process of welding. This leads to the speedy destruction of the stay-piece, for water penetrating these openings will rapidly out away the iron by oxidation. By my invention these objections are avoided, and I make the stay-piece continuous, avoiding the welding, securing the required strength and lightness, and greatly diminishing the cost of'nianufacture.

Referring to the drawings forming part of this specification, Figure l is a perspective view. Fig. 2 is a cross-section, and Fig. 3 is an elevation of the back of the hame with the stay removed.

A in said drawings represents the hame, which is made of wood in the usual manner. The back of the hame is formed, as shown in Fig. 2, with a fiat-surfaced ridge, a, extending hame, and lie closely against the surfaces at b c,

with its edges resting upon the seats (I and e. The outer surface of the stay is rounded transversely, and its edges are squared off, as shown at f f, so that said portions are nearly parallel with eachother. The stay made in this form is riveted to the hame in the ordinary manner. By making the stay of the peculiar form shown and described, I am able to roll it out between roller-dies,thereby avoiding the costly and tedious method of hand forging and welding heretofore employed. Moreover, the shape of the stay is such as to give it the required strength without thickening the metal at the curve of the hame, and I am thereby enabled to use a rib having uniform thickness throughout. This will readily appear from the fact that as the stay fits closely upon the flat top and angular sides of the ridge upon the back of the hame, it not only receives lateral support therefrom, but also has that shape which, in accordance with well-known laws of physics, best enables it to resist bending and torsional strain.

Instead of forming the hame A with a flat surface, a, upon its back, the inclined sides I) and 0 may be so formed as to meet each other, in which case the rib B will be rolled with an angular groove in its lower face. Other forms I also may be employed without departing substantially from my invention. The ridge upon the back of the hame is continuous throughout its length, except at those parts where the wood is cut away beneath the stay. Instead of rounding the back or outer surface of the stay, it may be made flat, if desired.

Having thus described my invention,what I claim is 1. The combination, with a hame having a and c, and seats cl and e, of the iron stay B,

ridge or rib formed upon its back, with sides I which incline toward seats upon each side of said rib, of an iron stay rolled in a continuous piece of uniform thickness and extending from end to end of the hanie, said stay being convex upon its outer surface, and shaped to fit closely upon the rib of the hanie, its edges lying in the seats and beveled off exteriorly to form flush surfaces with the sides of the hanie, substantially as described. 7

2. The combination, with the hanie A, having the angular ridge to, with inclined sides 72 formed in a continuous piece, fitting upon said haine, in the manner described, the outer surface being rounded and its edges f f squared off, substantially as described.

3. A wooden haine having formed upon its witnesses.
