, v {.1 LEBAVHIDS T0 all'whom it may Be it known that I, 11m n) of A drian, in the county of Lenawe'eandState .of Michigan, have invented new and useful structing the draw-bar-or draw-head with two enlargements orshoulders, at a suitable distance apart, to serve, bycoming in contact with suitable abutment-s in its movement, as stops to protect the draw and buffer spring or springs from undue strain, and to support the draw-bar in-lcaseof the failure offs-aid springs.

' It further consists, in combination withfthe above, in a superior mode of applying and supporting the draw-ban and the draw and bufi'e springs.

In the drawings, Figure 1 represents a plan view of one end of the bed-frame of a car provided; with my improved draw-bar arrange ment, and Fig, 2 a vertical longitudinal sec- A'represents the bed-fr'ameof the car, which may be constructed of the usual form and materials, having-in it at each end, in the form of a pair of cross timbers orsills, BO, arranged at a suitable distance from the ends, between two central longitudinal sills, and a central protuberance or buffer-plate, D, on the outer side of each end sill, each being suit-ably perforated, as provision for the reception of the draw-head or draw-bar and its appurtenances. E represents the draw-head oi' draw-bar, which may be constructed in anyusua-l or suitable manner, and is provided on its outer or front end with a suitable coupling, and at suitable distance apart, and in such relative position as to be on each side of the front sill of the frame when in position, as represented, with a pair of enlargements or shoulders, e e, which, in the normal position of the parts, as

"represented,.are at a distance from the respective sides ofsaid end-piece equal to the desired extent of the 'movemeutin each direci 7 Specification forming part or Letters Patent'No. 93,5 84;'iistsdlhlgisti jest-.5

I represents a pin traversing the rear end of the draw-bar F, to secure omit the disks G H;

which is placed loosely on the draw-bar F'between the disks G H..

K represents atruss rod extending across the frame A, beneath the buffer-plate 1).,to support said plate and the front sill of the frame, on which the greatest strain falls.

In operation, as the draw-head E recedes on its collision by or with another, the disk G slides back on the mid F, compressing the spring J, which abuts, in this partof the operadeaden the shock which\jtouldwtherwise reult.' On the compression offtii'c spring-J to the extent which has been deemed-ladvisable, the shoulder-or stop e, coming in contact with the bufi'er-plate D, arrests the movement, and

prevents the undue straining of the spring.

Being formed as shown and described; the draw-head provided with them may be made as readily and nearly as cheaply as without.
