COMBINED DERAILER AND RERAILER.

SPECIFICATION forming part of Letters Patent No. 758,994, dated May 3, 1904,

Application filed July 6,1903. Serial No. 184,409. (No model.)

To (ti/Z whom it puny concern:

Be it known that I, GEORGE L. lVlANsEIELp, a resident of the city of Chicago, county of Cook, and State of Illinois, have invented a certain new and useful and Improved (Joinbined Derailer and Rerailer, of which the following is a specification.

My invention relates to means for derailing cars or trains that have not the right of way upon railroads and also relates to means for rerailing cars or trains that have been derailed.

Derailers of the class to which this inven tion belongs are usually provided at the ends of side tracks, their purpose being to derail cars which from accidental causes may start toward the main track. To keep such a moving car from passing out through the switch and onto the main track, where it might collide with a train on the main track, it is necessary to derail the car before it reaches the main track, and when the car has thus been derailed it is desirable that it shall be replaced upon the track as quickly as possible.

To this end my invention consists, primarily, in a rerailer or replacing-frog that is placed alongside of the railroad-rail and is adapted to be moved over the same into position to guide the wheels of the derailed car upward and onto the track-rail.

My invention particularly consists in a cornbined derailing and rerailing frog or switch that is movable toward and from the trackrail and which when in position is adapted to either displace or replace the car-wheels that pass overit, suitable means being provided for operating the frog or switch to position the same upon the rail or remove it therefrom.

My invention also consists in the combination of a derailing frog or switch with the slide-guides therefor, which are fixed near the track-rail, and means for sliding the frog thereon, and, further, my invention consists in various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, in Which- Figure 1 is a plan view of a combined derailer and rerailer embodying my invention.

4 L are tie-plates that are spiked to the tiesand which are provided with the integralhorizontal guides 5. These guides are parallel and are perpendicular to the track-rail. The tops of the guides 5 preferably rise to the height of the track-rail and serve to guide the plate or frog 6. Said plate is provided on its under side with the T-guides 7 7, that receive the parallel guides 5 in the parts 7 7, which contain the T-slots and are preferably integral with the plate 6 and have under-hanging parts 7 which serve to hold the plate on the guides 55. The guideso are preferably recessed to reduce the friction between the parts. For operating the plate 6 I employ a rocking shaft 8, that is held in the lugs 9, which are preferably integral with the guide-plates 1. This shaft is operated by means of the arm 10, which is connected with a suitable lever or to the nearest track-switch stand. The plate 6 is provided with depending lugs or webs 11, and these contain the pins 12, by which the connection is made with the operating-arms 13 on the shaft 8. Said arms, as shown, are provided with slots l l, and when the shaft 8 is rocked the plate 6 will be moved either toward or from the rail 2.

15 represents the slot or recess provided in the under part of the plate 6 to permit the swinging of the arm 13 beneath it. The shoulders 16 on the lugs or ribs 11 strike the side of the rail when the plate is moved inwardly and serve as stops for the plate. The plate or frog 6 lies diagonally on the rail When resting on the same and is provided with a diagonal wheel-flange groove 17, which serves to guide the ear-wheels either off of or onto the rail, according to the direction in which the car is moved over the device. This groove lies between the inclined or diagonal ribs 18 and 19, that are integral with theplate 6. The rib 18 ends in an abrupt wedge or incline 20 above the rail and is sufficiently high to lift the tread of a car-wheel rolling upon it and prevent the flange of the wheel from striking the plate 6 at the bottom of the groove. From the high point the rib 18 slopes downwardly to the top level. A car-wheel rolling thereon is moved laterally by wedging engagement with the opposite rib 19. Thus the weight of the car is always carried directly above or outside the rail. The outer end of the rib 19 terminates above the outer side of the rail, and when a wheel has been taken into the groove of the derailer its continued movement will project it therefrom and off of the rail. The bottom of the groove 17 drops away suddenly at that end of the frog which is outside of the rail, affording a steep incline 17, defined by the sharply-inclined end 18 of the rib 18. At the bottom of this incline the frog has a foot 21, that is adapted to slide on a plate 22, provided on the wide tie 3. The bottom of the foot is ribbed, as shown, to minimize the frietion between the same and the tie-plate 22.

The cars that get loose while standing on a side track usually encounter the derailer while moving at a low speed, with the result that they are stopped as soon as the first truck of the first car is derailed, the wheels thereof becoming embedded in the road-bed. Derailments are frequently of a more serious character; but the greater number occur and resalt as above stated, and in such cases the derailed truck will be found to lie with its Wheels close to the track-rails. Under such circumstances and where my device is employed it is only necessary to couple the locomotive to the car or train and draw it back onto the track, the outer wheels of the truck being taken up by the quick incline 17 of the frog and forced inwardly by the rib 18 thereof while rolling over the frog. A stone or plank used at the opposite rail will lift the opposite truck-wheels at such times. The weight of the car at the moment that a truck-wheel strikes the quick rerailing-incline of the frog is carried by the foot 21, and the friction between the foot and the plate 22 is sufiicient to prevent the forcing out of the frog by wedging action of the opposite wheels against the opposite track-rail. On the other hand, if a car enters the track behind a derailer the first truck-wheel that strikes the derailer will either Wedge it off the rail or ride over the derailer and no part will be damaged.

The advantages of my device are as follows: It not only provides for the derailment of a car, but also provides for the immediate rerailment thereof. It is a positive derailer and a positive rerailer. 1n rerailing, the device may set out from the rail and will be drawn toward the rail by the lateral pull of the car.

The device is positively held against longitudinal movement on the rail and is so constructed that the wedging action of the carwheels when passing over the device in either direction tends to hold the device against and on the rail. The device has full latitude of movement, and when removed from the rail of the parts of a car-truck. Further, the device is composed of few parts, all of which are practically exposed, so that they can be easily inspected, cleaned, and lubricated.

As nu merousmodifications of my invention will readily suggest themselves to one skilled in the art, I do not confine the same to the specific constructions herein shown and described.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. The combined derailer and rerailer comprising the plate to lie upon a rail and having a diagonal groove to guide a wheel from either side of such rail to the other side thereof, substantially as described.
