GEORGE OKILL STUART OONXVAY, OF STONEFIELD, QUEBEC, CANADA, ASSIGNOR OF TWO-THIRDS TO JAMES COOPER AND FREDERICK FAIR- MAN, BOTH OF MONTREAL, CANADA.

RAI LWAY-CA R.

SPECIFICATION forming part of Letters Patent No. 308,830, dated December 2, 1884. Application filed July 29,1F84. (No model.) Patented in Canada August 9. 1884. No.19,955.

To aZZ whom it may concern:

Be it known that I, GEORGE OKILL STUART CONWAY, of Stoneiield, in the county of Argenteuil and Province of Quebec, Canada, have invented certain new and useful Improvements in Railway-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has reference to certain appliances to be attached to railway-cars of all kinds, and which come into action instantaneously upon a wheel or wheels leaving the rail, the breaking of an axle, or any other ac cident from which a car is likely to leave the road-bed and become ditched. These appliances serve in such a case to hold the trucks in their normal position with regard to the axis of the ear, thereby keeping the car in the line of the train and on the road-bed, even on the sharpest curve.

The apparatus which I have invented for the above purposes may be briefly described as consisting in shoes or bails suspended from the longitudinals ot' the car closely under the truck-transoms, so that if for any reason the wheels or any of them should leave the rails these transoms would immediately drop into and be held rigidly by the bails, thereby preventing the truck from turning, and keeping the car in the line of the train.

For full comprehension of my invention reference must be had to the accompanying drawing, forming part of this specification, and being a sectional View of one truck-frame of a car to which my invention has been applied.

A is one of the longitudinals of the car, 13 being the bolster, and O O G the transoms or truck-frames, all these being of any usual construction.

D is an iron bail or shoe, of suitable section and strength, turned up at the ends, on which are formed fiat eyes (1 d, and of sufficient length to allow, when in position, full play to the transoms when passing around a curve.

E E are chains hung by hooks e e to elevises F F, bolted to the longitudinals A, these chains passing through the eyes d of the bail D, and holding it, as shown in the drawing, just below the under side of the transomsOO. As these supports are free to run through the eyes or links d, they help to adjust the bails and keep them in proper position with regard to the truck-frames, whatever may be the curve or grade of the road. So long as the wheels remain on the rail the bails simply hang clear of all other mechanism under the truck-frames; but if from any cause the transoms drop they are received and held rigidly in the bails D D. and thereby prevented from turning in either direction.

Jointed or other rods suitably attached to the longitudinals and to the bails may be in some instances substituted for the chains E E.

\Vhat I claim as my invention, and wish secured by Letters Patent, is as follows:

1. In combination with a railway-car, safe ty bails or shoes suspended loosely from the car beneath the truck-frames, substantially as described.

2. The combination, with the truck-frame of a railway-ear, of thebails D, suspended to the longitudinals of the car by chains E E or other supports allowing of compensating play, all as herein set forth.

GEORGE ()KILL STUART CONWAY.
