Application filed November 12, 1885. Serial No. 182,515. (No model.)

To all whom it may concern:

Be it known that I, August FriebebtSHAUSER, of Sandusky, in the county of Erie and State of Ohio, have invented certain new 5 and useful Improvements in Pocket-Knives; and I do hereby declare the following to be a full, clfiar, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the ic same.

My invention relates to improvements in pocket-knives, in which the spring - back is dovetailed to the sides of the handle, the object being to provide a cheap and strong at15 tachment for these parts.

In the accompanying drawings, Figure 1 is a side elevation of a two-bladed knife embodying my invention. Fig. 2 is a plan view of the back of the knife. Fig. 3 is a side view 20 of the handle and a view in perspective of the spring - back, showing the parts detached. Figs. 4 and 5 are respectively views of the side and back Of a four-bladed knife embodying my invention.

The sides A of the handle are of metal, and have corresponding slots, «, in the back edge, the end walls of which are undercut, as shown. The spring-back B is provided with laterallyprojecting tongues or wings &, with beveled 30 edges, and made to fit the slots a, the parts, when assembled, forming dovetails. If there are one or more blades at each end of theknife, the tongues & should be located about in the center lengthwise of the knife, and maybe nar35 row; but if there are blades only at one end of the knife the tongues b may be located well toward the opposite end, and should be of considerable width to resist the torsional strain on the tongues caused by the action of the spring-back. A rivet passes through the 40 sides A laterally at each of the handle and secures the parts, and one or both of these rivets serve as pivots for the blades, accordingas there are blades at one or both ends of the knife. In case there are blades only at one 45 end of the knife, the rivet a' passes inside of the spring-back, the latter at this end curving up and corresponding to the shape of the sides to form a better finish. As there are no rivets passing through the spring-back, the latter 50 is made of a flat steel plate only thick enough to give the required stiffness to the spring. In addition to the metal sides A, of course any outside covering may be had for ornamentation or otherwise; but in the absence of any 55 such covering the sides A may be polished and plated, if preferred, so as to present a fine appearance. In this manner a strong, durable, and finely-finished knife may be made at a small initial cost. 6o
