SPECIFICATION forming part of Letters Patent No. 446,392, dated February 10, 1891.

Application iileclAugust 15, 1890. Serial No. 362,092. (No model.)

To all whom zit may concern:

Be it known that I, HUBERT F. PROBERT, of Three Rivers, in the county of St. Joseph, State of Michigamhave invented certain new and useful Improvements in Car-Trucks, of

which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to produce a truck that is complete in itself, that is adapted to carry interchangeably any sort of body that may be attached to it, that is so constructed as to carry its body evenly and smoothly without jarring or swaying, and is also so constructed that the wheels, boxes, and axles may be conveniently removed from the truck and afterward replaced without detaching the truck from its body.

In the accompanying drawings, Figure l is a side elevation of my improved truck; Fig. 2, a top plan view of the same. Fig. 3 is a view of a part of one of the side frame-pieces detached. Fig. et is a front view of a pair of truck-wheels, showing the relations to it of parts of my truck. Fig. 5 is a side elevation of the frame-work of one side of my truck detached.

Referring to the letters on the drawings, A

' indicates the side frame-pieces, each of which preferably consists of a pair of fiat metalbars set edgewise and separated by blocks B or the like and bound together by bolts O.

D indicates the lower middle bars, each being preferably made of fiat metal, bent at each end at right angles, and bolted at its ends to the outside of the frame-piece A.

E indicates the lower end bars, each being preferably made of flat metal and bent at one end at right angles and at the other end at an oblique angle and bolted at its ends to the outside of 'one of the frame-pieces A.

E indicates a pair of bars that are separated from each other by thimbles and are bolted to the inner side of the bars D and E.

F and Gindicate transverse stays that pass through the frame-pieces A and the bars D, respectively, and hold the parts rigidly to gether.

H indicates the wheels of the truck, that are carried inside of the frame by axles lin boxes J. rlhese boxes are carried in the spaces be- It may be added that fenders N maybe carried by any suitable means upon the frame at each end.

The above-described truck is a complete thing in itself, and, being' carried rigidlyupon the axles, is adapted to carry a motor, Where one is used, either upon the axles or frame or to supports secured thereto, as may be desired, which are adapted to give it a firm and rigid support.

Upon the top of the main frame above described is carried a body-supporting frame P, of corresponding dimensions with the main frame and preferably made of at metal.

Q indicates vertically-sliding brackets that are bolted in pairs to the lower side of theA body-supporting frame P and are adapted to move smoothly and freely along the outer sides of the adjacent bent ends of the bars D and E, as upon ways, and also to bear lat-erally on the outer sides of the frame-pieces A. By this means the body-supporting frame is carried securely upon the main frame, but may move freely in a vertical direction upon it.

The brackets shown and described are a convenient means' of movably securing the body of the frame to ways upon the main frame; but I do not desire to limit myself to the exact details in this respect. Any sort of ways upon the main frame, and a traveler upon the body-frameare contemplated by my invention.

R indicates springs,A preferably made of metal in spiral form; but any kind of spring may be used. They are distributed along the sides of the truck in suitable numbers, and are carried in bearings adapted for them between the body-suporting frame and the IOO , ing-frame and may be readily detached from itrwhen it is desirable to change one body for another.

By means of the construction above described I am able to distribute the springs between the body-supporting frame and the main frame, so as to attain a very etfective equalization of all motions, shocks, and strains that vmay be imparted through the main frame to the bodyesupporting frame and the body carried thereon. By this means and the location of the wheels Within the frame I am able to prevent the swaying inotion incidental to many kinds of street-cars, for instance, and thereby to contribute to the ease and oomfort'of passengers. At the same time I do this without disturbing the irmness of the parts that carry the car-motor when lit carriesv one.

What I claim is l l. In a street-car truck, the combination, with its Wheels and their axles, of side frames 'and oars D and E, secured thereto and bent so as to form spaces for the bearings of the axles, substantially as set forth.

2. In a car-truck, the combination, with its frame, Wheels, and axles, of vertical pockets in the frame, adapted to receive the bearings of the axles, and bars detachably secured to the sides of the pockets for closing them, whereby ready means for securing and detachingthe frame from the Wheels, axles, or bearings is provided, substantially as set forth.

3. In a car-truck, the combination, with the main frame, of a body-frame carried thereon, the main frame being provided with bars D and E, secured to it and bent so as to form Ways, and brackets upon the body-supporting frame, adapted to move vertically upon said Ways and to otherwise hold the body-supporting frame in fixed relations to the main frame, silibstantially as set forth.

Ll. In a car-truck, the combination, With the main frame', of a yieldingly-supported bodysupporting frame adapted to be carried thereou, the Ways upon the main frame, and brackets upon the body-supporting frame, adapted to travel upon the Ways and While restraining motion in every other direction to permit free vertical motion of the body-supporting frame upon the main frame, substantially as set forth. A

In testimony of all which I have hereunto subscribed my name.

HUBERT F. PROBERT.
