B. P. GROW. CABLE GRIP CAR.

UNITED. STATES PATENT OFFICE.

BENJAMIN F. CROIV, OF ST. LOUIS, MISSOURI.

CABLE-G RIP CAR.

SPECIFICATION forming part of Letters Patent No. 431,936, dated July 8, 1890.4

Application filed February 15 1390. Serial No. 340,534. (No model.)

To all whom -it may concern.-

Be it known that I, BENJAMIN F. CROW, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Cable-Grip Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved inanner of mounting -car-bodies on their trucks, and the invention is particularly designed for cable-grip cars.

Myinvention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top or plan View, part in section, illustrative of my invention. Fig. Il is a vertical section taken on line II II, Fig. I.

Grip car bodies have heretofore been mounted on their trucks without the use of the ordinary king-bolt arrangement, so that the grip can be placed centrally of the truck, so that in turning curves the grip willbe at the turning center of the truck, thus permitting shorter curves without the grip binding or coming into severe frictional contact with the slot-rails of the conduit. So far as I am aware, however, serious objections have existed in all such constructions heretofore devised, and to produce such a construction as will be satisfactory is the object of my invention.

Referring to the drawings, 1 represents part of the frame of the car-body, which rests upon and is secured by suitable means to an annular fiat ring 2, which has a downwardly-extending flange 3, preferably at its inner edge, as shown.

4 represents a fiat annular ring, corresponding in size to the ring 2, and whichis supported by and secured to the truck. (Not shown.) This ring is of course beneath the ring 2, and it is provided with a downwardlyextending flange 5, preferably at its inner 6 represents rollers placed, preferably, in pairs between the flat rings 2 and 4. These rollers bear on the ring 4, and the ring 2 bears on them, and they thus carry the weight of the car on the truck, permitting the latter to turn freely when rounding curves in the track. The rollers 6 are mounted in pairs on short shafts 7 and are held in their proper locations relatively to each other by annular rings 8, in which the ends of the shafts fit, (see Fig. IL) and which are held from horizontal movement by the flange 3. The ring 2 may be held from vertical .movement relatively to the ring 4 by clips 9, secured to its flange 3 and extending beneath the flange 5 of the ring 4. A construction of this kind permits the grip to be located in the center of the truck, while at the same time it is durable, cheap, and not liable to get out of order.

I claim as my inventionl. In a cable-grip car, the combination of the upper and lower annular rings 2 and 4, open for the passage of the grip, and frictionrollers 6, placed between the rings, substantially as and for the purpose set forth.

' 2. In a cable-grip car, the combination of the upper and lower rings 2 and 4, open for the passage of the grip, and rollers 6, arranged. in pairs and placed between the rings, substantially as and for the purpose set forth.

3. In a cable-grip car, the combination of the upper and lower rings 2 and 4, rollers 6 on shaft 7, and rings 8, all of said rings being open forthe passage of the grip, substantially as and for the purpose set forth.

4. In a cable-grip car, the combination of the upper and lower rings 2 and 4, having flanges 3 and 5, rollers 6, rings 8, and clips 9, all of said rings being open for the passage of the grip, substantially as and for the purpose set forth.
