IMPROVEMENT IN HEAD-BLCCKS FOR VEHICLES.

Specification forming part of Letters Patent No. 147,126,5Iatcd February 3, 1874; application filed February 10, 1872.

To all whom it may concern Be it known that I, PAUL M. GUTcHEs, of Galena, in the county of Delaware and State of Ohio, havel invented a new and useful Improvement in HeadBlock and Gear for Carriages, of which the following is a specification:

The invention will irst be fully described, and then clearly pointed out in the claim.

In the accompanying drawing, Figure l represents a vertical longitudinal section taken on the line w :v of Fig. 2. Fig. 2 is a back view. Fig. 3 is a plan view of the reverse side of the gear. Fig. 4 is a detail view of the under side of' the top part of the fthwheel. Fig. 5 is a detail, showing the friction-ball arrangement between the two parts of the fifth-wheel. Fig. 6 is a perspective of the head-block alone.

The head-block A is made of metal, and has formed with it, A in a single piece, the socket for the king-bolt B, the socket for the reach D, the upper part e of the fifth-wheel, and a socket or recess, 2, in its top, to receive the spring L.

The head of the kin g-bolt does not pass up through the block A and spring in the usual manner, but is heldin the socket g by ahead, 8, of any suitable kind, and a tubular nut, 71 which screws into the socket.

By this arrangement of parts the headblock and spring do not have to be drilled through, the parts are not uselessly weakened, and the nut which secures the block and bolt together is not exposed and liable to constantly work loose. The lower part of the bolt B is bifurcated, so as to straddle over the top of the axle-bed, and thus forms the clip F for securing the head -block thereto. The clipplate J has a screw-bolt, 4, projecting from its under side, which passes down through the curved brace I,.which passes down under the axle-bed, and has its ends fastened to the under side of the #head-block A, at the points k k', the projection or ear 5, extendingl outward from the back of the block A and cast with it, being formed for this purpose. In the top of the block A is formed an elongated recess, 2, in which is placed a cushion, of wood or rubber, It, upon which the spring L rests. This cushion equalizes the bearingsurface of the spring, and prevents the liability of straining or breaking it. The spring is secured in position by means of the two clips M, the ends of which pass down through the ears 6 formed with the block A, and the curved brace O having the plate N formed with it, which rests upon the top of the spring and passes under each of the clips. The front end of the brace O is fastened to the top ofthe screw-socket 7 by the bolt l?, which passes downward through both of the braces I O and end ofthe reach D. Cast with the block A, and forming part of it, are the two ears T, which project downward from the under side of the socket 7, and

form guides, between which the under part Cv ofthe fifth-wheel moves. This part C has a clip, S, formed with.it at each end, and by which it is secured in position; In order to make the two parts of the fifth-wheel move as easily as possible, the friction-roller V is placed under the under side of the part O, and in the under surface of the top part and top surface of the under part there are formed a number of circular grooves, U, shown in Figs. 4 and 5, in which are placed the friction balls or rollers 8. The reach D consists of a metal tube of any desired size, and has its front end provided with a screw, so as to screw it into the socket 7. Through this end of the reach is formed an elongated hole or opening,

9, at right angles to the reach, and through which the bolt P passes.

Bymeans of this hole the reach can be turned partially around in either direction, so that either one ofthe wheels can run down into a rut without straining or injuring the reach. The screw-thread prevents the whole strain from coming upon the bolt alone, and in case the bolt should break the thread prevents the reach from coming out of the socket.

y Near the rear end of the reach there is cut a slot, in which, from opposite sides, are in-y serted the shanks of the hounds x. These shanks y are just sufciently thick to fill the slot up flush with the surface of the reach and have the screw thread, which also extends around. the reach, eut in their Outer surface, so a socket 0r recess, 2, in its top, to receive a that by screwing up the nut z they will be secushion for the spring, the Whole being formed cured rnily in place. in a single piece of metal, substantially as set Having thus described my invention, I forth'.
