Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed April 21, 1905. Serial No. 256,710.

To all whom it may concern.-

Be it known that I, JOSEPH S. CoATEs, of Goshen, county of Orange, State of New York, have invented a new and useful Improvement in Sulkies, of which the following is a specification.

In a former application filed by me in the Patent Oflice on November 8, 1904, and serially numbered 231,878, I showed, described, and claimed a sulky having a truss or trusses formed and constructed in a novel manner. I showed, described, and claimed a truss made essentially of three members, which I designated as a first and outer member or members, as this part might be made in two sections; second, an inner member, and, third, an intermediate member.

These three parts were so constructed and assembled as to produce an ideal truss, both from the standpoint of strength as well as of lightness. In that application I showed the intermediate member as oining and becoming a part of the outer member or members at the center of the truss, and, similarly after traversing the plane of the truss, as joining and becoming one with the inner member at points approximately near and just above the hub-line.

I have found by experiment that this produces, as above stated, a light, strong, and durable structure peculiarly adapted for the purpose for which it was devised, and my present invention and application relate to and embody a similar structure, I having in the meantime developed my idea and having now embodied it in a still more improved form.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a rear elevation of my improved truss, showing the forward end or edge of the seat attached thereto. Fig. 2 is a similar view, the shafts of the vehicle being here shown in place and attached. Figs. 3 and 4 are detail views. Fig. 5 is a side elevation.

In the drawings, A represents the outer member of my improved truss. In this case and instance I make this outer member continuous, and I have shown it extending from and connected with the outer ends of the wheel-hubs, over and above the wheels and across from side to side of the vehicle.

The inner member is shown at B. This likewise extends from side to side of the vehicle and is attached to the hubs of the vehicle attheir inner ends.

special and peculiar manner I employ in joining the intermediate members 0 to the outer member A. These parts are formed of tubular metal, and the upper ends of the members C are provided with extensions D, also tubular, and the tubular portion or opening being of an area in crosssection coextensive with the entire area in cross-section of the part or member A where the parts are intended to be joined.

By referring to Fig. 3 I show how the member O is introduced upon and secured to the member A. By assembling the parts in this manner the part C can be drawn up to the position shown in this figure, then by a turning movement of one part upon the other the members can be drawn to the position shown in Fig. 4, at which point and when so turned and drawn they will be firmly locked one to the other. By reason of the fact that altho ugh the part A can slip through the tubular extension D of part C when in the position shown in Fig. 3, the parts when drawn to the position shown in Fig. 4 will form an extremely tight joint, inasmuch as the relation of the curve of the part A has changed in relation to the curve in the tubular extension D of the member C, and while, as stated, the parts when in the relative position shown in Fig. 3 will slip one on the other they will, when in the position shown in Fig. 4, be securely bound and locked. The intermediate members C so attached to the outer member A are joined to the inner member B at points I) just above the hub-line. The joinder may be efiected by brazing or by other suitable means or processes.

The seat is shown at S and is supported at its forward edge upon the lower member B of the truss and at its rear edge is supported upon the shafts L. The shafts extend rearwardlyand immediately beneath the points where the members 0 are joined to the members A of the truss and are supported upon the lower member B through intermediate bolsters R, or they may be directly supported upon the member B. Pins P extend downwardly through the members A, C, and B,the shafts L and bolsters R locking them all together at these points. Braces E extend between the shafts L and the inner members B and the usual pins, and thimbles T may be employed to strengthen and buttress the members of the truss, as shown, and also to bolster the seat upon the rear part of the shafts.

The shafts are shown of one piece, continuing around and at the back of the vehicle between the members of the truss, as ex lained, and supporting the rear edge of t e seat. The hubs are shown at H and the wheels at W. I employ braces V also extending between the hubs H and the shafts L, connecting them to the shafts at point 1.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. A sulky having a truss composed of an outer member, extending from side to side of the vehicle, over the wheels and connected with the outer ends of the wheel-hubs, a continuous inner member extending between the inner ends of the wheel-hubs, and intermediate members formed as shown, and secured to the outer member at points near its shoulders, and to the inner member at points above the wheel-hubs.

2. In a sulky, a truss-axle formed of an outer member, extending from side to side of the vehicle, over the wheels and connected with the outer ends of the wheel-hubs, an inner continuous member extending between the wheelhubs, and two intermediate members, one arranged on each side of the vehicle and secured respectively to the outer member approximately near its shoulders and to the inner member at points just above the hubine.

3. A truss-axle for sulkies and like vehicles formed of inner and outer continuous members and two intermediate members having hollow portions at their upper ends which fit over corresponding portions of equal area in cross-section of the outer member, and being locked thereto by a turning movement, and secured at their lower ends, substantially as shown and described.

4. In a sulky, or like vehicle, a truss having a continuous outer member, intermediate members having hollow portions encircling the outer member and locked thereto by a turning movement, and secured to the inner member.

5. In a sulky or like vehicle, the combination of a truss having a continuous outer member extending from the outer ends of the hubs and over the wheels as shown, a con tinuous inner member extending betweenthe inner ends of the hubs, two intermediate members locked to the outer member at points approximately near the shoulders of the same and attached to the inner member at points just above the hub-line, with the shafts resting on the inner member and secured to the intermediate and outer member by bolts, as and for the purposes set forth.

6. In a vehicle, a truss member extending from side to side and connecting the wheels thereof, the parts of the truss being locked together by intermediate elements secured by a turning movement to one part and by brazing to the other part.
