UNITED STATES ATENT OFFICE.
GEORGE W. COOK, OF ROOK ISLAND, ILLINOIS.
IMPROVEMENT IN RAI LROAD-CARS.
Specication forming part of Letters Patent No. 51,698, dated December 26, 1865.
lowing is a full and exact description thereof,
reference bein ghad to the accompanying drawings, and to the letters of reference marked thereon.
The nature of the invention consists in attaching underneath the car at each end four self-adjustable rollers, slightly elevated above the rails, which rollers, upon the car-wheels leaving the rails, will comein contact with the rails and immediately adjust themselves at a proper angle to incline and conduct the car directly back in the direction from which it came, thereby preventing the truck, or the wheels thereof, from coming in contact with the ground or ties, but keeping the body of the car directly over the track, the wheels either hugging the sides of the rails or rolling to their proper place.
To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.
Figure l represents an isometrical perspective View of parts of an inverted car-truck with attachment; Fig. 2, longitudinal section of the attachment; Fig. 3, a cross-sect-ion of the attachment at the line O on Fig. 2.
I construct my cars on any of the known forms, and to those constructed without reference to the attachment I attach my improvement in any manner and to any part of the locomotive, car, or truck which is most practicable to produce the desired result.
There are cars at present in use which will show the manner in which I make my attachment. They are constructed with timbers between the truck-wheels on a line with the axle thereof, as shown atAin Fig. l. I extend the length of this timber beyond the rails on each side of the track to a line taken up by the body of the car, as shown at P in Fig. 1. These timbers are fastened to iron bars or plates, which are attached to and connect the boxes on each side of the truck, as shown at R in Fig. 1. Underneath this timber Ifasten, by means of bolts or otherwise, the boxing B, either in sections, as represented at B B B B in Fig. 1, joining each together by means of bands, as shown at c c c, or in one solid piece where strength requires it.
I make the boxing of cast-iron, or any other metallic substance, and of sufficient thickness so that when the rollers D D D D are placed in the slots E E E E, as shown at Fig. 1, the.
rollers will project about one-fourth of their thickness below the boxing, thereby guarding the rollers against any contact except that which tends to turn them around. I also make the boxing wide, for the purpose of getting the inclines from the edge ofthe slots to the top edge of the pla-tes or boxing, in order that they may, in some instances, slide over obstructions, such as broken rails, &c.
At the outer ends of the two outside slots E E and the inner ends of the two inside slots E E, I make elongated and circular bearings to receive the rollers and permit the ends placed therein to play or swing from one side to the other, as shown at F in Figs. 1 and 3, thereby rendering the rollers self-adjustable as soon as they comein contact with the rails.
I make the lrollers of wroughtiron or any other metallic substance, from four to iive inches in diameter, or larger where strength is required. In order to prevent the rollers from sliding endwise when on the rails, I make shallow grooves with sharp ridges, as shown at Fig. 2.
rIhe bands c are made of wrought-iron, and intended to keep both the boxing and the rollers to their places, and can extend around the timber, as shown at Fig. 3, and there fastened with bolts, or around the boxing, as shown at Fig. l.
In order to use as small a roller as possible, I make one or more bearings on the boxing, between the ends of each roller, as shown at H H H Hin Fig. 2. This bearing should be of less width than that of the top ofthe rail, to prevent the rails from dropping in the corresponding bearing of the roller. The rollers should be elevated about two inches above the rails when in working order, and
should not touch the boxing; except at their in which they play, when applied to railroadpoints of bearing z' i 1) i i Mi 11i t', as shown cars and locomotives, for the purpose herein at Fig.2. described and set forth.
What I claim as my invention, and desire GEORGE W. COOK. to secure by Letters Patent, is- Witnesses:
The self-adjustable conducting-rollers D, in CHARLES BUFORD, J r.,
combination with their elongated boxing B, O. H. STRATTAN.
