JOHN M. PERKINS, OF SOUTH BEND, INDIANA.

CARRIAGE-=BOW SOCKET.

E PECIFEQATIQN forming part of Letters Patent No. 337,61 dated 9. 1886.

Application filed J anuury 7, IFEG.

To (:ZZ whom it may concern Be it known that I, JOHN M. PERKINS, a citizen of the United States, residingat South Bend, in the county of St. Joseph and State of Indiana, haveinvented certain newand useful Improvements in Bow Sockets; and I do hereby declafethefollowing to bea full, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same.

My invention relates to bow-sockets for carriages and similar articles, and has for its object the construction of a strong and durable article that cannot be broken. bent, oi split.

It consists, principally, of a combination with a suitable core or base of layers of thin veneer inter-wound with coarse open-woven cloth, the whole iirmly united by glue orother suitable cement; and in the construction of a bow-socket I add a double ferrule, all as more particularlyhereinalterdescrihedand claimed.

The employment of thin sheets of veneer glued together and textile t'abric in connection therewith is old; butin such cases it has been customary to arrange the sheets with the grain crosswise of the contiguous sheet, and when a textile fabric has been employed it has been of a close, fine material and used simply as a lining to the veneer. My invention in this respect differs in the fact that[ use the veneer in .very thin layers, the grain of which all runs the same way, and interpose between such layers layers of open-woven cloth known as scrim, and unite the whole by glue. The open meshes ot' the cloth permit the glue, which is used to connect the layers of scrim and veneer, to penetrate and surround the same, and to thus make a solid, substantial structure.

It is now a well established fact that with veneer or boards glued across the grain, with the grain ot'one piece placed at right angles to the grain of the other, the connection will not be as close, secure. and permanent as when glued together with the grain of the adjoining pieces placed parallel.

My invention is illustrated in the accompanying drawings, which show a section of the lower end of a bowsocket.

Figure 1 is a side elevation of the same, and Fig. 2 a longitudinal sectional view on line x m of Fig. 1.

Serial No. 187,840. (No model.)

A is the core of the socket, which may be either solid or tubular.

B is an aperture in which the end of a slatiron is inserted.

O is a layer of coarse cloth, like scrim, having open meshes and glued to the core. The glue is first laid on the surface and the scrim then applied thereto, and when pressed the open meshes ot' the cloth permit the glue to pass through and adhere to the next layer, D, which is a very thin sheet oi" wood or venee C is the next layer .of scrim, and D another layer of wood, with the glue applied between them and all pressed together.

E is an inner ferrule placed over the inside layers, 6 and D, of scrim and wood, and E an outside ferrule placed over the succeeding layers of scrim and wood. The outside ferrule is used for the reason that the ends of the veneer will sometimes crack when the slatirons are inserted and pressed hard into the socket.

One of the chief ClllfiClllllGS experienced in the making of ordinary lmw-sockets with a veneer-covering is the splitting of the veneer covering the socket on fastening the slat to the top bow, and when the top-prop is nailed or screwed in place in the top part of the socket. Great care is taken in the ordinary methods to prevent this by seeing that the grains of the respective layers cross each other at a right angle or nearly a right angle; but with this method a safe or reliable adhesion of the glue cannot be obtained, as already stated.

By my construction all difficulty of splitting or separation of the parts from the metal,due to driving the slat-iron in or to shrinkage, is avoided.

Closely-woven cloth or muslin will not answer the purpose of the open-meshed cloth or scrim that I employ, as both sides would have to be carefully covered and filled in with glue, whereas by the use of scrim the glue need be applied to but one side, when it will pass through the meshes and cover the opposite side when the succeeding layer of veneer is pressed on.
