For instance, any one of the Wheels may rise or fall in passing an elevation or depression in the road without affecting the other Wheels or straining the connecting-frame. The construction is also comparatively cheap and the joints are all simply and easily adjusted to take up Wear and prevent rattling,

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a motor-vehicle frame, the combination of the front and rear axles, two reachbars extending from the front axle to the rear axle and connected to both axles by universal joints, and two diagonal braces each connected rigidly to an intermediate portion of a reach-bar at one end and connected by a universal joint to an intermediate portion of the rear axle at its other end.

2. In a motor-vehicle frame, the combination of the front and rear axles, a forwardlyprojecting frame connected to the middle of the rear axle, reach-bars connected at their ends to the axles by universal joints, and braces each connected rigidly to a reach-bar at one end and having its other end connected with the. forwardly-extending frame on the rear axle by a universal joint.

3. In a motor-vehicle frame, the combination of an axle, a threaded stud secured at one end to the axle and having a concave seat or recess formed in its free end, a reachbar having at one end a ball-like projection adapted to t in said seat formed in the axlestud, and a threaded retaining-sleeve tting said stud and engaging With the ball at the end of the reach-bar to hold the saine to its seat on the stud.

4. In a vehicle-frame, the combination of axles having studs projecting therefrom provided With ball seats or sockets in their free ends, tubular reach-bars, balls secured to the ends of said reach-bars and adapted to lit said seats or sockets in the axle-studs, and sleeves adjustably connected to the axlestuds and engaging with the balls at the ends of the reach-bars to hold the same in their sockets.

5. In a motor-vehicle frame, the combination of the front and rear axles, the frame 7 projecting forwardly from the rear axle, the threaded studs rigidly connected to the front and rear axles and to said frame, the reachbars having balls connected to their ends, the threaded sleeves connecting said balls With the studs on the axles, the diagonal brace-rods having their outer ends connected rigidly With intermediate portions of the respective reach-bars, balls connected by the inner ends of said brace-rods, and threaded sleeves connecting said balls with the studs upon said frame.

In testimony whereof we affix our signatures in presence of two Witnesses.
