LOCOIMOTIVE-SPRING.

.5PECIFICATION forming part of Letters Patent No.350,629, latex". October 12', 1836.

(No model.)

To all whom it may concern:

Be it known that we, ROBERT H. ILLING WORTH and DE WITT O. SMILEY, J11, citizens ofthe United States, residing at Jersey City, in

the county of Hudson and State of New 'Jersey, and Newark, Essex county, New Jersey,

respectively, have invented certain new and to letters of reference marked thereon, which form apart of this specification.

The object of this invention is to provide, at a reduced cost of manufacture, a spring for use more especially in locomotives, railway- 26 cars, and other. vehicles, that will be more durable and avoid the great loss now sustained through the breakage of elliptic springs now very generally in use.

The invention consists in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each ofthe several figures, Figure 1 is an end elevation of a vehicle to which the improved spring is attached. Figs. 2, 3, and 4 are respectively top, side,'and bottom views of the spring in detail. Fig. 5 is a side view of the 3 5 device as applied to locomotives. Fig. 6 is a top view of-the same, and Fig. 7 is a view in perspective of a certain central bearing block or piece.

Heretofore helical springs have in some cases 0 been employed in connection with bearing arms or lovers in certain respects resembling those herein shown; but in the cases referred to the devices have been complicated and expensive, and defective in that the springs in 4 5 said devices have been arranged in sockets beneath central pivotal joints, so that should one of said springs break the removal of the broken parts and the substitution of a new spring would involve great labor and expense of time.

7 Again, in carriages oppositely-extending arms have been centrally pivoted upon a single pin arranged in suit-ablebearings, and have rested upon caps, beneath which vertical spiral springs have been stationed. This construction is defective, and especially so for 1000- motive purposes, in that the vertical arrangement of the springs takes up more room than ordinarily is afforded by the peculiar construction of the frame and other 00 operating parts of the said locomotive to get the necessary play.

In the improved device, by simply raising one of the lovers by a jack the broken spring may be easily replaced by another without the trouble referred to, and the spring-arms may he brought quite close to the frame.

In the said drawings, A indicates a portion of a locomotive frame or truck with which my improved device is connected. Bis a bearing, which forms a portion of the journal-box of the drivingwheel. O is a hearing or block, which is supported on said bearing B. This takes weight on its opposite sides of the frame or truck and the car, &e., thereon. Said block C separates the two horizontal springs, so that 7 5 they may act independently of one another, and is provided with ears or pivotal or fulcrumal bearings a on opposite sides thereof,-to receive oppositely-projecting arms I), which take the weight of the body of the vehicle from hang- 8o ers, straps, or portions 0, which are in one way or another connected with the body of the vehicle. Below said ears, on the opposite sides of the block 0, are seats (I (l, to receive theinner ends of helical springs e e, which latter may be held on said seats by pinsff or other suitable means. The said springs e e are arranged horizontally on each side of the center bearing and work horizontally, to allow a full spring action to be gained without consuming 0 or occupying undue vertical space.

. Upon the pivotal or fulcrumal bearings a a are arranged the arms I) b, which latter areprovided with depending bearings g 9. These are disposed at points opposite or approximately 9 5 opposite the seats d (l, and co-operate with saidseatstoholdthespringsin position. Pressure brought to bear on the extremities of the arms is received by the springs and transinit- 1 ance with the weight they are to bear, the

spring on the side of the center bearing correspomling with the heavy end of thelocoinotivebeing made much heavier than that on the opposite side corresponding with the less weighty end. This feature is of much importance in balancing the locomotive. as will be evident. By the construction described the accessibility of the springs is apparent. i

The invention can be applied to wagons, true-ks, carriages, and other vehicles, as will be seen npon reference to Fig. 1, and be used with the best results.

'Having thus described the invention, what we claim as new is- V Y 1. In combination with the frame A and hangers c of a locomotive, the central bearingblock, the oppositely-extending arms pivoted thereon, and horizontallyarranged springs separated by said block, said springs having their bearings on or between the sides of said block and arranged between said block and depending bearings, all substantially as and for the purposes set forth.

In testimony that We claim the foregoing we have hereunto set our hands this 28th day of October, 1885. l
