IMPROVEMENT IN KING-BOLT FOR WAGONS.

TO ALL WHO M IT MAY CONCERN:

Be it known that I, JonNJ. WALnnoN, of East Darham,;in the county of Greene, and State of New York,

have invented and made a certain new and useful Improvement in King-Bolts for Wagons, &c.; and I do hereby declare the following to be-a full, clear, and exact description of the said invention, reference being bad to the annexed drawing, making part of this specificatiomwherin- Figure 1 is. an elevation of my said king-bolt, as applied to the axle and bolster, and

Figure 2 is a section of the said king-bolt and the parts that it connects.

Similar marks of reference denote the same parts.

Heretofore the king-bolt has generally passed through the bolster or head-block, and heensepured by a nut above the spring. The k ingbolt has to be made small, in order to prevent injury to the head-block and spring by a large-sized hole; as a consequence, theparts wear away rapidly, and become loose from the con-' stant motion to which they are subjected.

The nature of my said invention consists in a socket'formed upon the plate that unites the perch and headbloek, said socket receiving the king-bolt, and forming a brace to the same, and presenting an extended surface. that prevents the parts wearing loose, and allows forthe introduction of a king-bolt that is much larger and stronger than could before be used with the same sized head-block, thus rendering the parts more durable and reliable in use. I v

In thedrawing, a represents a portion of the axle b and c are the fifth-wheels or segments; dis the bolster or head-b-lock-to which the perch e'is connected ,by the T shaped platef.

(j is the spring, and I). h the clips, by means of which the spring is held to the head-block 01. These parts may be of any ordinary character, so far as described.

I The king-boltz' is secured by the clip I: to the axle a, and its upper end passes into the socket Z. on the plate f, and the extreme end of said king-bolt is made smaller and passes through ahole in the platef, and is secured by the nut 0, that is countersunk in the bolster d, or said king-bolt may pass through the bolster d and spring 9, and terminate with a screw and nut, the smaller part only of. said king-boltpassing through. I

The king-bolt z, in the socket Z, taking an extended bearing, and being of a large size, is very strong and durable, and the bolster or head-block is not weakened.

What I claim, and desire to secure by Letters Patent, is-

The'socket Z, projecting downwards from the platef, that unites the perch c and bolster or head-block d, in combination with the king-bolt i, that enters,- at its upper part, said socket l, and is retained by the nut a above said platef, as and for the purposes specified. I i

In witness whereof,- I have hereunto set my signature, this thirtieth day of December, A. D. 1867.
