LOCOMOTIVE-TRUCK SPRING-HANG ER.

SPECIFICATION forming part Of Letters Patent No. 558,399, dated April 14, 1896. Application fil d January 25,-1896. Serial No. 576,860. (No model.)

To all whom it may concern.-

Be it known that I, OHARLEs LINSTROM, of Vicksburg, in the county of Warren and State of Mississippi, have invented a new and Improved Locomotive-Truck Spring-Hanger, of which the following is a full, clear, and eX- act description.

The object of the invention is to provide a new and improved locomotive-truck springhanger, wherein the springs and equalizingbars are not forced out of their proper position, usually caused by heavy shocks or jars incident to the wheels passing over the railjoints.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is an enlarged end elevation of the hanger with the equalizingbars in section. Fig. 3 is a sectional side elevation of the hanger on the line 3 3 of Fig. 2, and Fig. 4 is a cross-section of the same on the line 4 4 of Fig. 3.

The locomotive truck is provided with equalizing-bars A, arranged in pairs, one pair for each side of the truck, and resting on the journal-boxes B in the usual manner and as indicated in Fig. 1. In each pair of bars A are held transversely-extending pivots C, on which are fulcrumed the downwardly-extending spring-hangers D, provided at their free ends with curved seats D for the free ends of the leaf-spring E, so that the latter is free to yield lengthwise, owing to its support on the said hangers D.

Each hanger D is preferably of the construction shown in Figs. 2, 3, and 4that is, each hanger is provided with two forks D and D engaged transversely by the pivots C,

and the equalizing-bars A fit between the members of the forks, as will be readily understood by reference to Fig. 2. The innermost members of the forks D and D are rigidly connected with each other by a crosspiece D', so that a very strong hanger is obtained.

By the arrangement described each leafspring extends between two equalizing-bars on each side of the truck, and the seat D in each hanger is at the center thereof, so that the load is well distributed. It is understood that one-third of the entire weight of the 10- comotive rests on the leaf-springs E, and if the latter are not properly hung they Will soon be out of alinement and uneven relatively to each other, so that the springs are twisted and the weight of the engine is not distributed equally on all the spring-bearing surfaces. The twisting of the springs often repeated causes them frequently to break, notwithstanding that the springs have never exceeded the proper limit of their elasticity.

By the improvement above described it is impossible to force the springs out of their proper position.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A spring-hanger provided with two forks for engagement with the pivots of equalizingbars, the inner members of the forks being rigidly connected with each other, and the said forks being adapted to receive the equalizing-bars, substantially as shown and de scribed.

CHARLES LINSTROM.
