CHARLES E. LINDSAY, OF TERRACE PARK, OHIO.

DERAILER.

SPECIFICATION forming part of Letters Patent No. 593,304, dated November 9, 1897.

Application led September 9, 1897. Serial No. 651,024. (No model.) l

T0 all whom t may concern.-

Be it known that I, CHARLES E. LINDSAY, a citizen of the United States, residing at Terrace Park, in the county of Hamilton and State of Ohio, have invented certain'new and useful Improvements in Derailers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a reliable derailer of simple and cheap construction.

To this end my invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like notations refer to like parts throughout the several views.

Figure lis a perspective view showing the derailer as it appears when in working position, some parts of the track being broken away. Fig. 2 is a plan view of the parts shown in Fig. l, with the truck-wheel in position to show the direction of approach; and Fig. 3 is a detail showing the fixed part of the locking device.

The numerals l represent the ties, and the numeral 2 one of the rails of the track.

3 represents a pedestal or stand adapted to be secured by spikes 4 to one of the ties on the inside of the track-rail 2. To said pedestal or stand 3 is pivoted by bolt 5 the derailing bar or arm 6. This arm or bar 6 is of the proper shape to overreach the rail 2 and be secured to one of the ties on the outside of the rail by the customary switch-lock. For this purpose the arm 6 is curved near its outer end, as shown at a, and then again extended substantially parallel with its body portion to form a foot-like extremity a', which is provided with a suitable slot a2 for engagement over the upper end of an eyebolt 7. The eyebolt 7 is preferably formed with a lag-screw stem, adapting the same to be tightly secured to the tie, and the head of the bolt is provided with a suitable eye for receiving the lock-pin 8 when the derailer is in working position, as shown in Figs. 1 and 2. The stand 3 and the eyebolt 7 are properly positioned in respect to each otheron opposite sides of the rail 2,

ner of said arm, and thereby the wheel will be made to climb ,over the ball of the rail and be guided off by the body of the derailingarm to the outside of the track, thus derailing the car.

The expanded foot portion a at the outer end of the arm 6 gives a large bearing-surface at the tie for assisting the lock and the stand in preventing the derailer from being overturned under the action of the Wheel.

The broadening of the arm 6 begins at the point a, just before the downturn of the arm and extends to the outer end, with sufficient spread to deflect the wheel-flan ge laterally and make the wheel clear the lock when the drop occurs. This avoids breakage or injury of the lock.

A derailing device constructed as above described is very reliable and is very simple and cheap to make. It is especially well adapted for preventing cars from side tracks on grades running back down onto the main track, thereby insuring the prevention of the serious accidents which might otherwise occur. It is well known that cars when standing on side tracks on grades will sometimes get started at most unexpected times and when no means are available for controlling the movement of the same. By the provision of the derailer herein disclosed and the location of the same near the lower end of the side track or other desired point it is always possible to get a limit to the travel of the runaway car.

Moreover, another important feature of advantage in this form of derailer is the fact that it does not weaken the rail and is always available.

By actual usage I have demonstrated the e'iciency of this device for the purposes had in view.

lVhat I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. A derailer, comprising an arm adapted IOO to over-reach a track-rail and be secured, at its opposite ends, to the fixed track structure, on opposite sides of said rail at an acute angle to the rail in the direction of the cars approach, substantially as described.

2. A derailer, comprising a pedestal or stand, an arm pivoted to said stand, and adapted to overreach the rail, and a locking device for the free end of said arm, with said stand and said locking device secured to the track structure on opposite sides of the rail, in position to permit the arm to stand at an acute angle to the rail, on the side of the approaching car, when in Working position, substantially as described.

3. The derailer comprising the stand 3 and the eyebolt 7, made fast to the track structure on opposite sides of the rail, the arm 6 pivoted to the stand 3, at its inner end, adapted to overreach the rail, and having a downturned outer end with slot adapted to engage CHARLES LINDSAY.
