THOS. E. ROBERTS, OF ALAMANOE COUNTY, NORTH CAROLINA.
TRUCK FOR RAILROAD-CARS, &C.
Specification of Letters Patent No. 25,139, dated August 16, 1859-.
lb all whom "it may concern:
Be it known that I, Trros. E. ROBERTS, of Alamance county, State of North Carolina, have invented certain new and useful Improvements in Center Bearings for Trucks for Cars, Locomotives, and All Hailway-Carriages; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the let ters of reference marked thereon.
Similar letters of reference marked in the several figures indicate like parts.
Figure 1 represents a crosswise sectional view of truck frame, and also bottom sill of car. Fig. No. 2, represents top view of bolster piece of truck frame with face view of center, and side bearings. Figs. 3, 4L, 5, 6, 7, 8, 9, 10, are details of Fig. No. 1.
Invention.-The nature of my invention consists in the construction of twocast iron concave chilled plates; and securing one upon the bottom sill of the car, and the other upon the bolster of the car truck, with a double sided cast iron chilled, convex plate between, and in connecting and combining this center bearing, with self oiling friction rollers, at the ends of the bolster, to impart to the car body; an easy motion while the truck is free to yield universally to all the inequalities of the road, with very little friction or abrasion of the parts of the center bearing, all as will be hereafter seen.
Oonstruction.To enable others skilled in the art to which my invention appertains, to construct and carry out the same, I will describe it as follows:
A is bottom sill of car.
B, B, are two separate concave chilled cast iron plates firmly secured respectively to sill A, and bolster D.
C is an oval or double convex bearing or plate, working or playing with ease between the two plates, B, B, and kept therein by circular lips it, formed on these plates for that purpose, and against which the edge of the convex plate C, impinges and comes in contact, the object of the play of the convex plate C, between the lips h, is to relieve the concussive shocks which would otherwise. be received by the car body, load, and machinery, and this is very important.
The three parts, B, B, C, combined forms the center bearing which works universally with the greatest ease.
E E, represents two kingbolts that secure the car to the truck frame. They are placed firmly through the sill A, and through holes in top plate B as represented in Fig. No. 8, by T, but rotating freely through slots in bottom plates B, and I as represented by M M, in Figs. 2, and 4.
I is a stud plate secured to bottom of bolster D, supporting truss rod J G, O, H, are friction rollers caps and self oiling box secured to each end of bolster D to support, and equalize the weight of car or engine goin around curves where one side of track is graded higher than the other.
F F are plates of iron secured to the bottom of sill A for the rollers G, G, to rotate against.
In Figs. 3 and 4, L represents top view of stud plate I with slots M M; K, a longitudinal sectional view of stud plate I.
In Fig. No. 5, H represents a box in which roller G runs, and O, a cap to box H. The box is so constructed as to hold oil, that when the roller G rotates, it becomes its own lubricator, and letting the truck rotate when curving; with greater ease than the ordinary friction slide now in common use.
P, and S represent face view of top and bottom plates B, B.
Q, Fig. 6, represents face view of the oval or double convex bearing or plate, O.
R in Fig. 7 section of plate O.
U, V, in Figs. 9 and 10, represents a longitudinal sectional view of concave plates B, B.
The arrangement of my center bearing; and its combination with my friction rollers G, O, H, is necessary in carrying out my invention, as the necessary yielding movement is first obtained by the peculiarity of my center bearing, and then this yielding movement is controlled by the side friction rollers G, O, H which perform their governing function with ease, and with very little abrasion, and they are self oiling; that is they oil themselves and the plates F, F, with which they come in contact the oil being retained in the boxes H, and so that the periphery of rollers G, is immersed in it and consequently imparts the oil to the plates F, whenever it comes in contact with them.
WV WV, represents car wheels, X represents the axle, Y the pedestal that supports the box in which the journals of the axle turns Z the boxes.
Having thus fully described my invenplate C With each other in the manner detion I will state that I do not claim a ball scribed, and their combination With the self 10 and socket joint as that forms no part of my oiling friction rollers G, O, H, for the purinvention.
What I claim as new and desire to secure by Letters-Patent is The construction and arrangement of the concave chilled plates B, and convex chilled poses fully set forth.
