.To all whom, it may concern Be it known that I, MYRICK DUDLEY, of

Lynn, in the county of Essex and Common-` wealth ofv Massachusetts, have invented certain 5 Improvements in StreetBailway Switches, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to meansv for working the switches of railways, and the nature thereof is fully described and specifically claimed hereinafter.

Figure l is a perspective view of a car-truck, a portion of the platform being broken awa-y to show the operating mechanism. Fig. 2 is a perspective view of a detached portion of the mechanism.

In this invention I make use of a switch-bar, A, that is provided with a cross plate or bar, d, on which are the upwardly-projectingpieces or lugs b c. Said parts may be constructed integral with the bar A,or may be separately formed and secured thereto. In all other respects the rails are the same as now in common use.

The mechanism designed for operating the switch A is represented, mainly, in the second igure of the drawings. It comprises the bar B, on which are fixed the downwardly-projecting feet or bosses c f, the operating-lever D, provided with swiveled fulcrum h and handle 7. These parts are attached to the car, as fully shown in Fig. 1. For the purpose of attaching these parts to the car I employ plates E, Fig. 1,which are secured to the car-axle boxes, and said plates are provided with heads F, having slots 4, adapted t receive the ends of bar B. Said bar is arranged in said slots, as shown,and permits vertical movement, to the end that it may be lifted so as to raise the feet e f high above the rail whenever occasion requires. The'bar also permits lateral or endwise move1nent,to theend thatit may be moved to carry the feet e or f, as occasion requires, into line for engaging the projections b or c and moving the switch-bar A.l The bar B is operated by the workman through the instrumentality of the lever D. To this end the lever D is secured,by means of the plate k, to the bottom of the car-platform, as shown, thereby 5o forming a swiveled fulcrum for the suspended .the rail.

lever. The rear end of said lever is connected,

as shown,with a pin, 6,which is secured in the bar B. The forward end of said lever extends forward and upward, terminating, as shown,

in a handle, 7. The bar B, when idle, is depressed by its own gravity, as represented in n Fig. 1. The feet efare then in line with and just above the rail and operate as a fender to remove any small obstructions that maybe on In operation the foot e or f, as occa- 6o sion requires, is brought into line for engaging the projections b or c, as occasion requires,and thereby carrying the switchbar into position, as required, to .give the desired direct-ion to the car. A

In Fig. l the foot f is in position to engage the projection band switch or move the bar A, so as to permit the car to turn the curve; but suppose the bar A were out of line with the straight rail, and yet it might'be desirable to 7o send the car along the straight rails. In this case the foot would be shifted into position to engage the projection c and move the bar4 A into line with the rail. These various movements of the bar B to position the feet e andf are effected by the workman, who grasps the handle 7, depresses the lever D, thereby lifting it outof a notch in thecar-platform, (not shown,) and then movesitto the right or left, as occasion requires, to give the desired movement to the barB. Thisbeinggained,thehandleisreleased. The lever D is then lifted by gravity of bar B, and the end of the lever D, falling into a slot or over a pin in the car-platform, is secured from further movement until the switch-b ar has been passed.

The projections b c, it will be observed, are beveled or inclined iu one direction. This is done to the end that the feet ef may be lifted and pass over the projections when the car travels in the opposite direction.

It should also be observed that the end of lever D is connected with bar B by meansof a pin, 6, the lever being allowed free movement along the pin, as shown, to the end that these parts may not be cramped and broken by the rocking movements of the car.

I claim- 1. In a railwayswitch,and in combination, the switch-rail A, provided with one or more Ico projections, the bar B, provided with feet ef, said feet being rigidly attached to the bar which extends from side to side of the car,and the lever D, for operating the bar, substan- 5 tially as described.

. 2. In combination, the switch-rail, the bar B, arranged transversely of the car and having the feet e f secured thereto and supported thereby, the said bar having vertical and transro verse movement, and the operating'lever D,

all substantially as described.

3. In combination, the bar B, having feet e f, the operating-bar D, and the switch-rail provided with projections, said projections being W'itnesses:
