FIFTH-WHEEL PLATE.

SPECIFICATION forming part of Letters Patent No. 281,357, dated July 17, 1883.

u Application filed February 16, 1883. (No model.)

To all whom it may concern:

Be it known that I, CoRNELIUsT. GANDY, of Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Plates for Fifth-Wheels and I do hereby declare that the following is a full, clear, 'and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apart of this specification, and in whieh- Figure I is a perspective view of my improved ifth-wheel plates. Fig. 2 is a vertitical section through the same. top view of the lower plate, and Fig. 4- is abottom view of thev upper plate, separated from each other.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of fifth-wheel platesin which both the plates have a number of concentric and corresponding annular projections and grooves fitting into each other; and it consists in the improved construction and combination of parts of two plates of this class, in which the bearing-surfaces are conical or beveled, for the purpose of taking up wear, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the lower plate, which is fastened upon the swiveled front portion of the running-gear, and B the upper plate, which is fastened to the rigid portion of the wagon, both plates having bolt-holes for the introduction of fastening bolts or screws. l The lower plate, A, has a central aperture, C, from the sides of which projects a conical hollow sleeve, D, through which the king-bolt passes. A low annular projection, E, surrounds the base of this sleeve, forming a receptacle for the oil used in lubricating the'king-bolt and the bearing-surfaces of the two plates, the oil passing out through the perforations e in the annular rim as it is used.

The front rim of the lower plate is provided with an upward and inward bent lip, F, the inner surfaces of which form circular segments, and the inward-bent edge G of which is beveled inward and downward. A similarly- Fig. 3 is a slides upon a rearward-projecting arm, J, of

plate A, and is fastened adjustably upon the same by means of set-screws K,passing through a longitudinal slot in the base-plate I into screw-threaded holes in arm J, so that the plate and its lip may be adjusted closer to or farther off from the center of the plate A.

rlhe upper plate, B, has a central aperture, M, the edges of which form a downward-projecting hollow conical sleeve or collar, N, which fits over the upper portion of sleeve D, and by the shape of the two sleeves they will always wear to a seat, thus insuring a perfect fit of the two plates upon each other.

An annular box or downward-proj ecting rim, O, projecting from the under side of plate B, incloses the conical sleeves, preventing access of dirt or sand, and bears with its lower edge upon plate A, immediately around -the annular rim E; and two segmental lips, P, project from the lower edge of box O-one forward and one rearward-catching under lipsF and H, so that if, by accident, the king-bolt should break, the lips engaging each other will prevent the swiveled portion of the runninggear from separating from the body of the vehicle. The outer surface of the boX O forms a portion of an inverted cone, and the beveled lips F and H, bearing against it, will always wear so as to t tightly the inclinations running in the same directions in the lips and the box.

It will also be seen that any wear in the lip H may be taken up by adjusting it closer to f the box, so that itwill catch sufficiently over the lip -P to hold it in case of accident to the king-bolt. Y.

The lips F and H and P occupy each somewhat Y less than one-fourth'of the circumference of the circle they form segments of, so that'by turning the plates at right angles to each other they may be separated, the lips then being free of each other. These plates may also, with a slight change, be used in connecting double-trees to a wagon, or singletrees to a wagon or double-tree, the one plate being fastened to the stationary, and the other plate to the pivoted, part, with abolt pass- SCI IOO

sleeves upon the plates.

I am aware that iifth-wheel plates have been made in which both the plates have annular concentric and corresponding projections and grooves, and I do not claim such construction broadly; and likewise that fth-wheel plates have been constructed having a sliding lip upon the one plate engaging an annular or segmental flange upon the other plate; but

Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

The combination of the upper plate having the annular sleeve and box, provided with the diametrically-opposite segmental lips, the lower plate having the annular sleeves and projections tting into the sleeve and box of the upper plate, and provided with the rigid CORNELIUS T. GAND Y.
