SWITCHING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 612,063, dated October 11, 1898. Application filed January 18, 1897. Renewed March 5, 1898. Serial No. 672,778. (No model.)

To all whom it may concern:

Be itknown that I, GEORGE W. SINGLETON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Switching Mechanism, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in switching mechanism for railways, and has for its object the production of a simple and efficient device for enabling the motorman or other occupant of a vehicle or car movable along a railway to govern the operation of the switches of the railway; and to this end the invention consists in the general combination, construction, and arrangement of the parts of a switching mechanism, all as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a diagrammatic view of a vehicle or car and a portion of a railway provided with my improved switching mechanism. Fig. 2 is a top plan of a portion of said railway and the terminals secured to the vehicle or car. Fig. 3 is a transverse vertical section taken on line 3 3, Fig. 2. Fig. tis a detail section, partly broken away, taken on line 4 4., Fig. 3; and Fig. 5 is a detail section taken on line 5 5, Fig. 3.

A A A A are the rails of main and branch tracks of a railway, B a frog for uniting adjacent rails A A, and O a vehicle or car movable along the railway. The tracks A A body of the'frog B is provided at one end with a series of openings 5 arranged beneath the free extremity of the switch-point b for receiving dirt or other material accumulating between the adjacent portions of the rails 12 b. The opposite end of said body is formed with a depending hollowhub Z2 and a depending bracket b having a substantially horizontal lateral extension or arm arranged beneath the lower face of the hub b This lateral extension supports a rock-arm B or other electrically-operated means rigidly connected to the switch-point b and is usually formed with a socket in its upper face, in which a depending projection or hub provided upon one end of said rock-arm is removably arranged.

The switch-point b is provided at one end with a depending spindle 11 j ournaled in the hollow hub 5 The lower end of the spindle 12 preferably projects beneath the lower face of said hub, is formed angular in cross-section, and is removably arranged in an aperture of similar shape provided in one end of the rock-arm B, which is removably mounted on a suitable support, as the lateral extension or arm of the bracket b, and remains in position on said lateral extension or arm, even though the switch point is removed from the frog. The opposite end of the rockarm B is provided with oppositely-arranged lateral projections 19 b and independently;

her B arranged beneath the frog B. Said the upper ends of the cores of the electromagnets and their opposite extremities provided with shoulders engaged with the outer faces of said upright walls. The chamber B is detachably connected to the lower face of the frog B and is removably supported above a receptacle or catch-basin 13 provided with a manhole B and an overflow-conduit B. Said chamber B usually consists of a substantially upright rectangular body and is provided with a chute B which extends forwardly beneath the openings 1) in the frog B and conducts to the receptacle or catchbasin B the dirt, water, or other material discharged through said openings.

Corresponding ends of the coils of the electromagnets B are connected to a grounded conductor, as one of the rails A, and their opposite ends are connected to separated electrical conductors or terminals Z7 Z1 which may be supported above the rails A A A A, although they usually consist of bars or strips of metal interposed between the rails A A of the main track in advance of the frog B. The terminals 19 are engaged by the lower ends of movable terminals 0 c, insulated from each other and suitably secured to the Vehicle or car 0, which may be of any desired construction. The terminals 0 c are preferably pivoted at their upper ends to the vehicle or car C and are forced into engagement with the terminals h Z9 by suitable manually-operated means, which usually consists of a vertically-reciprocating foot-pieced, pivoted to the terminals 0 c. A suitable spring 0 is connected to the foot-piece c and the vehicle or car 0 for normally elevating the foot-piece and retracting the terminals 0 c from operative position. The upper ends of said terminals c c are electrically connected to separated terminals 0 c of an electric switch, which is supported on the vehicle or car 0 and is provided with a movable switch member 0 electrically connected byany suitable means to a grounded electric conductor, as a trolley-wire O.

The switch member 0 is movable into e11- gagement with either of the terminals 0 c and when the terminals 0 c are in operative position the circuit is completed by said switch member between one of the electromagnets and the trolley-wire O, whereupon said electromagnet is energized and rocks the switch-point h in the desired direction. The terminals 0 c are usually arranged at the end of the vehicle or car 0 in close proximity to the motorman, and as it is usually customary to use either end of a vehicle or car as an advance end I have here shown each end of the Vehicle or car 0 as provided with terminals c c, foot-pieces c, springs 0 switchterminals 0 c and switch members 0 of similar construction. I have also shown each end of the vehicle or car 0 as provided with suitable signals, as lamps c 0 which are connected in shunt to the conductors leading from the terminals 0 and by their failure to operate or afford the usual illumination inform the motorman whenever the potential of .the current flowing through either of said conductors to the corresponding electromagnet is insufficient to energize said electromagnet and effect the desired operation of the switch-point of my improved mechanism.

The operation of my switching mechanism will now be readily understood upon reference to the foregoing description and the accompanying drawings.

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