SPECIFICATION forming: part of Letters Patent No. 281,307, dated July 17, 1883.

Application filed October 10,-18E2. (No modem 1 To all whom, it may "concern.-

Be it known that I,.WILLIAM G. SHIPHERD,

of Cleveland, in the county of Ouyahoga and.

State of Ohio, have invented certain new and useful Improvements in Fifth -Wheels for Wagons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to fifth-wheels for vehicles; and it consists in the parts and combination of parts, as will be hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a view in perspective of a fifth-wheel embodying my invention. Fig. 2 is a vertical cross-section, taken through my fifth-wheel, showing its construc tion more clearly. Fig. 3 is a view in section of a part of my device, showing another manner of forming a washer which'I use in connection with my device.

A represents an axle of a vehicle, to which is secured, by means of suitable clips, B B, the lower plate or segment, 0, of my fifth-wheel.

Extending out from the segment G, and rearward of the axle A, is a conoidal-shaped pivot, D, on which is journaled the upper segment, E, of thefifth-wheel.

Between the bearing F of the upper segment, E, and the pivot D is a packing, G, of leather, rubber, or other like or suitable material. The function of this packing G is to prevent any noise that might arise from the contact of the two metals.

From the bearing F of the upper segment an arm, E, extends downward, and is prolonged rearward, as shown at e, this rearward pro longation being bolted to the upper side of the coupling-pole P. To the lower side of this coupling-pole is bolted an arm, M, which projects forward of the axle, and is bent upward, as shown at M, this upwardly-bent portion being shouldered, as shown at m, and having above said shoulder a screw-threaded portion, m, which passes through a radial cross-bar, e, of the upper segment, and secured thereto by a nut, m

While the arm E and its rearward f dered portion serve as an additional means'of attachment, and also to firmly brace and support the forward-projecting portion of said upper segment.

H is a bolt, which is provided with a flat head, and also with an angular or irregular shaped portion contiguous to the head, said angular portion fitting in an opening, a, which passes vertically through the center of the pivot D. .This opening may be of any irregular shape to correspond to the irregular-shaped portion of the bolt and prevent said bolt from turning.

Beneath the pivot D is a recess, I, which is adapted to receive a spiral spring or an elastic washer, I, through which the lower or threaded end of the bolt Hpasses. (See Fig. 2.) The nut J, which is screwed on the end of the bolt H, acts to compress the spring or washer I against the end of the recess, and thus the bolt H is prevented from making a noise, while it is loose enough to allow of the free revolution of the upper segment.

K is a bolt, the head of which is formed at a right angle to the shank. This bolt K is secured in a socket, K, on the upper segment in such a manner that its head extends under and acts to support the lower segment. The socket K extends downward across and below the edge of the lower segment, and is open on its rear side, in order that the head 70 of the bolt K may project laterally directly from the socket, so that the side walls of said socket will prevent said head from swinging sidewise and escaping from under the lower segment, which it would otherwise be liable to do. The threaded end of the bolt K is provided with an elastic or spring washer, which may be a spiral spring, as shown in Fig. 2, against which the nut L impinges, thus acting to take up any wear that may occur between the parts, and prevent the noise that would result from such wear or loosene'ss.

It is obvious that, if desirable, the conoidalshaped pivot may be secured to the upper segment and the journal to the lower segment. It will operate equally as well either way.

What I claim is- I prolongation e serve as a means of attach- 50 ing the upper segment firmly to the couplingpole, the arm M and its upwardly-bent shoul- 1. In a fifth-wheel or turn-table of avehicle, the combination, with the conoidal pivot D of the lower segment, of the corresp onding-shaped bearing F of the upper segment, and the interposed packing G, substantially as described, and for the purpose set forth.

2. The combination, with the axle and the lower segment secured thereto, and having the attached pivot in the rear thereof, of the upper segmenthaving a bearing to receive said pivot, and provided with the radial cross-bar e, and the downwardlyextended arm E, having the rearward prolongation 0, the coupling-pole having said prolongation secured to its upper side, the arm M, secured to the under side of the coupling-pole, extending forward under the axle, and having the upwardly-bent portion ll secured to the radial cross-bar of the upper segment, in front of the axle, and the spring-controlled angle-bolt arranged to hold the forwardly-projecting upper and lower segment together, substantially as described.

3. The combination, with-the lower segment, of the upper segment having a socket extending downward across and below the front edge of said lower segment and open at its rear side, and the bolt extending through said socket and having a head projecting laterally therefrom directly under the lower segment, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
