The latter action causes the straightening head 10 to be 5 brought into engagement with the bent portion of the stake B so as to bring about the straightening of the stake. The device is shown as being applied to a car of shallow depth.

When used in conjunction with a car of greater depth the-tie straps 13 will be secured to the lower end of the frame beneath the cylinder. I

It will thus be seen that I have provided 15 a highly novel, simple, and eflicient coal car stake straightening device that is well adapt ed for all the purposes heretofore designated.

Even though I have herein shown and described the invention as consisting of certain detail structural elements, it. is nevertheless to be understood that minor changes may be made therein without affecting the spirit and scope of the appended claims.

Having thus describechny invention, what I claim as new is:

1. -In a coal car stake straightening device, a frame unit, means associated with one end of the frame unit whereby to facilitate its attachment to the upper edge of a wall of the car directly above the upper end of the stake to be straightened, means whereby the lower end of the frame may be secured in spaced relati0n-with the car, a cylinder associated with the frame and having a rectilinearly movable piston therein, a lever pivoted at one end to the forward end of the piston rod and at its opposite end to the said frame and a straightening head associated 40, with said lever and adapted to be moved into engagement with the bent portion of the stake when ressure is admitted into the cylinder in bac of said piston.

2. In a coal car stake straightening device,

an inverted L-shaped member having a finger on the lateral portion thereof for hooked engagement over the upper edgeof the car, above the upper end of the car stake, means pivotally disposed on the vertical portion of the L-shaped member having a finger thereon for engagement with the lower part of said car, a lever ivoted at one endto the-lateral portion 0 said L-shaped member, a straightening head arranged on said lever,

and power means associated with the other end of said lever for forcing said straightening head into engagement with the bent portion of said stake.

\ In testimony whereof I aflix my signature. so CAREY E. STRAUSBAUGH.
