GEORGE G. HUNT, OF BRIDGEPQRT, CONNECTICUT.
lMPROVEMENT IN CAR-TRUCKS.
Specification forming part of Letters Patent No. 45,609. dated December 27, 1864.
To all whom it may concern;
Be it known that I, GEORGE G. HUNT, of the cityof Bridgeport, in the county of Fairfield and State of Connecticut, have invented erence n arked thereon.
The nature of my invention consists in so constrncting'the trucks of railroad-cars that the axles and axle-boxes may be readily removed from the truck-t'ramewith greater ease and facility than has heretofore been done; also, in making the main trussbolts of the truck adjustable, in order to bring the strain more perfectly upon the trusses in a longitudinal direction.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
The accompanying drawing represents a. side view of my improved truck, which is constructed chiefly of iron, and in which M M are the top and bottom plates of the frame;
K K, the trusses; P P, the axle boxes; A A,
1 8 8; B B, the journals or axles; N N,
the springs; D 1) and E E, the bolts for connecting the axle-boxes with the truck'trame; E F, the main truss-bolts, which are made adjustablcby means of the nuts H I! and I I Z, the center beam of the truck; J J, collars or washers for the purpose of stiffening the bolts, 1 F. l is a top view of the axle-box 1.
The bolt 1) passes through the top and bottom plates, M M, and the truss-plate K, and also through an opening in the axle-box P, as shownat 0 in P; The bolt E also passes through the same plates and truss plate, but
, tits into a slot cast in the axle box, as shown at R- in P. The bolt 1) may also tit in'o a. slot instead of passing through the opening 0,
and .I. usually construct them in that manner.
In order to remove the axle-wheels and axleboxes from the truck-frame,1 raise the end of the truck from which they are to be removed a trifle-say one-eighth to one-quarter of an inch-and then unscrewthe nuts from and remove the bolts D, when the axle and axleboxes can be easily rolled out of the truck frame. I
The main truss-bolts F F have threads out upon them extending from the small end to the bottom of the center beam, Z. The nuts G Gare screwed firmly against the center beam, and sustain all the weight that is placed upon said center beam After the frameof thetruck is put together the nuts H H are screwed down firmly against the collars J luntil the strain is brought upon the truss-plates K Kin a 101igitudinal direction, The nuts H H can at any time be raised or lowered in order to increase -or diminish the longitudinal strain of said trusses. Without these adjustable bolts F F it isnlmost impossible to putjhe truck-frame together in such a manner but that too much strain will be brought upon the topplate, M, and too little upon the truss-plate K. By the use of these adjustable bolts I am enabled to make a much stronger truck-frame with much lighteriron than is ordinarily used.
It will be observed that in the model there is a duplicate of the truck-frame shown in the drawing, which is placed upon the opposite side of the wheels; but, as the double frame constitutes no art of the invention for which I claim Letters Patent under this application, I have not considered it necessary to describe it.
I claim- 1. The slotted axle-boxes P 1, in coin ination with the movable bolts D I) an the truck-frame, for the purpose of removing the axles and axle-boxes from said truck frame with facility and dispatch.
2. The adjustable bolts F F, in combination with the truss K, in order to bring the weight of the car chiefly upon said truss, and thus throw the strain upon said truss in a line with the grain oi the iron. GEO. G, HUNT. Witnesses: HORACE Nrcnotis,
I. A. BISHOP.
