CAR-DERAILING DTEVIIGE.l

Specification of Letters Patent.

Patented May 3U, 19106.

Application led February 12, 1915. Serial No. 7,697.

To all whom 'it may concern Be it known that I, THOMAS MGWATTERS, a subject of the King of Great Britain, residing at Glassport, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Car-Derailing Devices, of which improvement the following is a specification.

My invention relates to improvements in devices for derailing cars, and is particularly applicable for use in connection with coal trains.

Heretofore, so far as I am aware, there has been no efiicient device capable of derailing a train of coal cars when desirable to prevent the utter wreckage of the same.

In operating coal mines it is usual to load the coal upon a number of cars which when connected in the usual manner form a long train. Not infrequently these trains in descending inclined tracks get away from control and speed down the inclined tracks at such rate that when they come in contact with abutments or other devices at the end of the inclined tracks, they telescope upon one another, occasioning the wreckage of the entire train. iHours are consumed in clearing up the wreckage, during which the track is out of commission.

The object of my invention is to produce a device adapted to derail the car to which it is attached within a very short distance and thus prevent the train from obtaining dangerous momentum. I accomplish this object by means of the device hereinafter more specifically described, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a coal mine car with my improved derailer attached thereto. Fig. 2 is a fragmentary sectional view of a section of the car and derailer on line 1 1 of Fig. 1. Fig. 3 is a plan View of the derailer. Fig. 4 is a side elevation of the same. Fig. 5 is a bottom plan view of the portion of the derailer in contact with the rail. Fig. 6 is a left end view of the device as shown in Fig. 3. Fig. 7 is a right end view of the same. Fig. 8 is a plan view of the angle support for the derailer.

Fig. 9 is an end elevation .of the same showing the link or arm whereby the derailer is attached to the car. Fig. 10 is a side elevation of the same. Fig. 11 is a plan view of mine track showing cars in the act of being derailed by the device.

Referring to the drawings, l, is a coal mine car of the usual and ordinary type, adapted to be mounted upon rails, 2. A derailing device comprising a block, 3, is preferably formed of cast steel, as shown in Fig. 3 and has its surface adjacent to the rail preferably provided with serrations, 4f, as shown in Figs. l and 5. The upper portion or top of said block is provided with an inclined groove, 5, in which the flange, 6, of wheel, 7, is adapted to engage when the derailing device is in the position shown in dotted lines in Fig. 1. When in this lposition, the flange of the car wheel enters said groove and is guided or directed from the rail as shown in Fig. 11.

8, is a link or arm pivotally connected to the block, 3, of the derailing device, the upper end terminating in a hook, 9, adapted to engage over a pin, 10, secured upon the side of the car.

l1, is a prong which is pivotally secured upon the rear end of the block, 3, of the derailer, and is adapted to engage in the surface of the earth as soon as the oar attempts nto move backward in the event of a break in the cable. When this occurs, the link is thrown upwardly thereby disengaging the hook, 9, from the pin, l0. The device when so disengaged rests upon the rail in the path of the car, the Harige of the wheel entering the groove, 5, derailing the car and stopping the train before the same has traveled any great distance or acquired great momentum, thus saving the train from complete destruction, which normally occurs upon the happening of such accident.

Having described my invention, what I claim and desire to secure by Letters Patent, is

l. In a device for derailing coal cars, the combination of a car, a derailing device detachably secured to said car and adapted to travel therewith on vthe rail, the said derailing device having a prong pvotally secured In testimony whereof, I have hereunto to the rear end thereof.
