To afZZ whom, it may concern:

Be it known that I, ViLLI'AM DALTON, of Schenectady, in the county of Schenectady and State of New York, have invented a certain new and useful Improvement in Cushioning Appliances for Locomotives, of which im rovement the following is a specification.

he object of myfinvention is to provide means for the prevention of the jars, shocks, and injury to track-rails resultant upon the heavy blows struck thereon in the side lurching or abrupt lateral movement of locomotives when running at high speeds. This destructive action, while exerted 'to a substantialdegree in the operation of steam-locomotives, is not as great as in the case of electric locomotives, by reason ofthe fact that in the former the center of gravity of the machine is above the spring suspension, and the springs on opposite sides being comparatively close together, as the frames are located inside the wheels, side blows on the railscaused by lurching of the locomotive are in a measure cushioned by the pressure of the locomotive on the spring, which causes a portion of the blow to be expended in downward. pressure on the rail, tlie action being that of. an inverted pendulum. in electric locomotives the heavy motor-weights are hu ig between the wheels and the center of gravity is below the spring suspension, and under these'conditions lurching'or abrupt lateral movement of the locomotive exerts heavy side blows on the rails, which are injurious to them and to the locomotive.

My invention is designed to so cushion the side blows referred to that the impact of the locomotive upon the rail will be reduced to such an extent as to prevent the objectionable results experienced at high speeds in present practice. y

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a view, partly in section, showing an axle of an electric locomotive, with its Wheels, axleboxes, and pedestal-shoes, illustrating an applicatjon of my invention; Fig. 2, a side view in elevation of a portion of. the locomotiveframe,showin'f an axle-box and wheel; Fig. 3, a horizontal section, on an enlarged scale, through a pair of pedestal jaws, shoes, and an adjacent wheel-hub Fig. 4, a similar section,

on a further enlarged scale, through one of the jaws and shoes; Fig. 5, a vertical section through one of the shoes on the line c a of Fig. 3, and Fig. 6 an outer end view in elevation of the shoe.

My invention is -herein exemplified as applied in connection with an axle 2 of an electric locomotive, upon which wheels 4 are secured and which is'journaled in axle-boxes 3 in the ordinary manner. Pairs of l lateral flanges 3l and 3 are formed in the axle-boxes, and pedestal-shoes 5e are fitted in the spaces nr side recesses between said flanges. Each of the shoes 5e is provided with lateral flanges extending on o posite sides of a pair of vertical pedestal-jaws 5b, fixed on and constituting part of one of the side frame members of the locomotive, the construction providing for vertical movement of the edestal jaws and shoes relatively to the ax e-boxes and being .as thus far described one which is Well known in ordinary practice. v

In the practice of my invention as herein illustrated in structural detail, which has been found desirably adaptable in actual service, a vertical recess 5f is formed in one of the side flanges of each of the pedestalshoes 5e, and a plate-spring 10, having one or more leaves, as desired, is fitted in each of said recesses. The ends of the spring 10" or of the outer leaf, if more than one 1s used, bear on seats 5g at the ends of the recess 5f, and the middle portion of the sprino or of the inner leaf, if more than one is usedb, bears against the adjacent side of the pedestal-'aw 5l', as clearly shown in Fig. 5. Sufficient 'clearance is left between the side flange of the shoe on the, outside of the4 roove 5 andthe pedestal-jaw to admit of t e lateral movement of the axle-box and shoe and the compression of the spring in resistin such lateral movement in direction towar it, as most clearly appears by reference to Fig. 4. As

motive construction, the shoes 5'e are interposed between the axle-boxes and pedestaljaws-merely to act as liners or bearing-surfaces for the axle-boxes, and therefore the location of the springs 1() in the inner flanges of the axle-boxes instead of in the shoes, as in the instance shown, would not-invo`lve any departure from the spirit and operative principle of my invention.v .Y
