FIFTH-WHEEL.

SPECIFICATION forming part of Letters Patent No. 307,894, dated November 11, 1884.

Application filed July 17, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. YOUNG, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Improvement in Fifth-\Vheels or Circle-Plates for Connecting the Front Axle of Four-\Wheeled Vehicles to the Gearing, of which the following is a specification.

This invention relates to that class of fifthwheels which are constructed and adapted for use in cases where the king-bolt is located in front of the axle, and is passed through circle-plates,which are also projected in front of the axle; and the invention consists in certain features of construction hereinafter described, and specifically set forth in the claims.

The object of my invention is to obviate the rocking or side motion now common in wagons, and, further, to provide a safety-hook which, in connection with interlocking circleplates, will hold the axle-gearing together if the king-bolt should be removed or broken. I attain these objects inthe mannerillustrated in the accompanying drawings,in which similar letters of reference indicatelike parts.

Figure l is a perspective view of a part of a wagon embodying my invention, and Fig. 2 is a vertical longitudinal section of the same.

A is the axle. Bis the head-block, G the spring, and D the reach.

E is the upper circle-plate attached to the head-block K and reach D, and F is the lower circleplate fastened to the axle A. Both of these plates E and F extend in front of the axle, and have a large working surface,which, together with the hollow stems a b, which form parts of the upper and lower plates, re

spectively, and through which the king-bolt G is passed, obviates the rocking motion.

H is the safety-hook, secured at one end to the reach D, and passing down under the axle is bent up and fastened to the top plate, E. The bottom of the hollow stem 1) on bottom plate, F, fits into the lug c on the upper surface of safety-hook H, which holds said hollow stem 7) in position. On the upper surface of bottom circle-plate, F, is another spherical lug, (Z, which fits into the upper plate, E, and, in connection with hook H, prevents the two circle-plates E F from separating, and thereby holds the axle and gearing together when the king-bolt G is broken or removed.

By reference to Fig. 2 it will be seen that thebolt G is neither tapered nor shouldered at any point below its angular or square head, so that the full strength thereof is utilized, and ease of manufacture thereof is secured. The lower end of the bolt is screwthreaded, as also is the bolt-passage through the safety-hook or brace H, so that by turning the head of the bolt the plates E F and hook H are firmly bound together, rendering the nut on the bolt below the hook either unnecessary or with merelythe function of a set-nut. The function of the recessed lug c of the safetyhook is, primarily, to form, in connection with the stem I), a permanent kingbolt, or parts that act as such in the absence or breakage of the bolt G, said parts in such case being held in operative position by the connection therewith of the safety-hook at the top of the plate E, at the bottom of the stem 1), at the bottom of the axle A, and at the bottom of the reach D.

I am aware that the king-bolt has heretofore been placed in front of the aXlein wagons and thrashing-machines, and I do not, therefore, claim such a device, broadly, as my invention; but

Vhat I do claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the plate E, having the hollow stem a, terminating below the upper surface of the head-block, and the plate F, having the hollow stem 1), said stems being located in front of the axle, with the safety-hook I-I, having the recessed lug c, and secured to the plate E and to the reach D, substantially as specified.

2. The combination of the safety-hook H, secured to and extending from the reach to upper circle-plate, and having an intermediate recessed lug, 0, the plate F, having the hollow stem b, resting in said recess, and the bolt G, substantially as-specified.

3. The upper circle-plate, E, secured to the reach and bolster, in combination with the lower circle-plate, F, secured to the axle,

and the safety hook H, connected with both neetecl with the lower end of the slezn of the plates, the axle, and the reach, substantially plate F, and secured to the top of the plate as specified. E, substantially as specified.

4. The combination of the plates E and F, GEORGE H. YOUNG. 5 each having hollow stems located in front of Witnesses:

the axle, and the latter having the lug d,with WALTER CHAMBERS,

the safety hook H, secured to the reach, con- XV. H. FLUKE.
