DERAILER FOR RAILWAYS.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application led May 9, 1906. Serial No. 316,013.

To @ZZ whom it may concern:

Be it known that I, WILLIAM R. COCHRAN, Jr., a resident of Delphos, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Derailers for Railways; 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 vuse the same.

My invention relates to an improvement in derailers for railways, the object of the invention being to provide improvements of this character of extremely simple construction, cheap to manufacture, strong and durable in use, and which absolutely prevents a train passing from a siding onto the main track when the maintrack is open.

A further object is toprovide improvements of this character which permit a train to pass onto the siding after the switchpoints are thrown, but automatically sets to prevent any return of the train until the switch is opened.

With these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view illustrating my improvements. Fig. 2 is a view in section on the line a: thereof, and Figs. 3 and 4 are detail views.

1 represents the outside rail of a siding, and 2 my improved derailer, which is located some distance from the switch, as is customary.

The derailer comprises two main partsnamely, the derailer proper, 2, andits support or carrier 3. The support or carrier 3 has a small platform 4 and an outward extension 5. The platform 4 is secured to an :arm 6, which latter and an arm or extension 7 on the derailer are pivotally secured, as shown, permitting both to move vtogether or the derailer to move independently, as will hereinafter appear. The derailer rests on platform 4 and is recessed to receive the rail l and project its top portion over the rail, forming a tread portion 8, onto which the wheel-tread rides, elevating the wheel-ange onto the derailer, the latter being dished, as shown at 9,

to prevent the wheel-flange violently striking the same and permitting it to ride easily onto the derailer and move against a cam or diagonal fiange or web 10 on the derailer and be guided 'thereby off the rail.

The derailer is provided with a rod 11, secured thereto and movable in a perforated lug 12 at the outer end of extension 5, and a coiled spring 13 is located on this rod between the lug 12 and the derailer to normally hold the latter on platform 4, a lug 14 being provided on derailer 3 to compel the derailer to move back from the rail when the platform 4 is moved.

A link 15 connects the arm 6 with the switch-throwing mechanism, (not shown,) so that when the switch is thrown the derailer will also be moved, as will now be eX- plained.

The operation of my improvements is as follows: The derailer is maintained in the position shown in Fig. 1 and is moved only when the switch is thrown to open the siding. As the train passes from the main track onto the siding the switch is of course held open; but after the last car has passed the switch the siding is closed when the last car is some distance from the derailer, and the latter will be moved over the rail when the switch is thrown. l However, this will not interfere with the rear end of the train passing onto the siding, as the wheel-flanges will engage* the arm 7 and force the derailer back against the tension of spring 13, which latter will return the derailer to normal position over the rail. Any movement of the train toward the main track before the switch is open will cause the wheel-treads to ride on the tread portion 8 of the derailer, which will guide the wheel-fianges against the cam-web 1() and derail the car. It will thus be seen that while the wheels can pass the derailer when moving onto the siding even though the switch be closed the wheels cannot pass to the main track until the switch is open, and my improvements are an absolute preventative for accidents due to this cause.

A great many slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself IOO l l l at liberty to make such slight changes and alterations as Jfairly fall within the spirit and scope of my invention.

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

l. The combination with a movable support, of a derailer movable on the support, means for moving the support to move the derailer away from rail, and said derailer constructed to be moved independently of the support, by a wheel passing in one direction but derail the Wheel in passing in the opposite direction.

2. The combination with a rail, of a derailer, an arm thereon pivotally secured to one side of the rail permitting the derailer to be moved by a wheel-flange engaging the arm, a tread portion on the derailer supported on the rail7 a deflecting flange or web on the Vderailer to be engaged by a Wlieel-iange Awhen the wheel rides up on the tread and defleet the wheel from the track7 and a recess between the tread portion and iange to permit the wheel-flange to ride onto the derailer Without violently striking the same.

3. The combination with a rail, of a platform, an extension thereon, a pivoted arm secured to the platform, a derailer, an arm thereon pivotally secured to the pivotal end of the platform-arm7 a rod on the derailer movable in a lug on the extension, a spring on the rod bearing against the derailer, and a lug on the derailer to engage the platform.

4. The combination with a rail, a movable platform, means for connecting the latform with a switch-throwing device to ook the platform against movement when the switch is thrown, of a derailer mounted to move on the platform and constructed to be moved by the flange of a wheel in passing in one direction and to derail the wheel when passing in the reverse direction, and elastic devices normally holding the derailer over the rail.

5. A derailer, having a pivoted arm made with a cam edge to be engaged by a wheellange to move the derailer out of the path of a wheel when the Wheel is moving in one direction, a tread on the derailer supported on the rail tol receive the wheel and elevate the lange of the wheel, and a cam liange 0r web on the derailer to be engaged by the wheeliiange to deiiect the same from the rail.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
