RAILWAY-SWITCH THnow R;

7 '0 all whom it may concern:

Be it known that I, SAMUEL LEVY, a sub ject of the Czar of Russia, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented anew and Improved Railway-Switch Thrower, of which the following is a full, clear, and exact description.

This invention relates to railway appliances, and has particular reference to means for controlling the position of a switch point from the car, and by the term car as used hereinafter, I wish to be understood as covering any type of railway rolling stock from which the movable switch point may be operated or controlled.

Among the objects of the invention, therefore, is to provide an attachment for the switch point adapted to be operated by the actuation of one or the other of several plungers carried by the car and adapted to be depressed by the motorman or other operator, according to the direction in which the switch point is to be moved.

l/Vith the foregoing and other objects in View the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation of a part of the car and indicating a part of the track structure in longitudinal section on the line 11 of Fig. 3; Fig. 2 is a plan view of the track adjacent the switch; Fig. 3 is a front elevation of the car with parts in section on the line 33 of Fig. 1; and Fig. 41 is a vertical transverse section on the line 44 of Fig. 1.

Referring more particularly to the drawings, I show at 10 the rails of a track on which cars are presumed to be operated in the direction of the arrows and having associated therewith a movable switch point 11 leading to a side-track 12.

At any suitable place along or between the rails 10 is a bedplate 18 having vertical longitudinal slots 14 adjacent the opposite ends of the plate. The bed plate 13 is preferably depressed at or below the surface of the street or roadway and constitutes a housing Specification of Letters Patent.

or protection for the mechanism constitutmg the subject matter of this invention.

Beneath the bed plate 13 and a forward. extension 18 thereof, I arrange rock shaft 14 parallel to the line of movement of the cars and supported upon standards 15 and 16. This rock shaft has a crank 17at'its forward end and its rear end is provided with a miter gear 18. At 20 Ish'ow a rod connected at 21 to the arm17 and having its other end attached at '22 to the SWitCLll point 11. i

At 23 is a base structure having uprights 24 in which are journaled a pair of shafts 25 and 26 inaxial ali'nement with each other and in the horizontal plane of the rock shaft 14. To the inner ends of the shafts 25 and 26 are connected

miter gears

27 and 28 respectively, both inconstant mesh with the first mentioned gear 18, whereby a rotation of the rock shaft and its gear in either direction from one of the

shafts

25 or 20 will cause a corresponding rotation ofthe other shaft inthe opposite direction. The

shaft 25 carries an arm 25 atthe end opposite the gear 27 and the shaft 26 carries a corresponding arm 26*. The arms 25 and 26' are so mounted upon their shafts that they are normally arranged at an angle to each other from the axis of the shafts. In other words, as shown in Fig. 1, when the arm 25 is upright the other arm is inclined forwardly.

In this normal position the arm'25 projects upwardly through the slot 14 and bears against the rear end of such slot. The slotted portion of the plate 13, however, is depressed or concave so that the upper end of the arm 25 projects above the slot but not above the plane of the plate and is in position to be engaged by a plunger 29 carried by the right hand side of the car and adapted to be depressed against the force .of the spring 30 by the foot of the operator. When the plunger is thus depressed it will engage the upper end of the arm 25? causing a forward and downward movement thereof around the axis of the shaft 25 with a corresponding rotation of the gear 27. This rotation of the gear 27 will cause a rotation of the gear 18 and rock shaft 14 toward the left causing the crank 17 to draw the switch point to the left, opening the switch to the side track. While the arm 25 is thus moving forwardly and downwardly the opposite arm 26 will be moved in an opposite direction to its upright position where it may Patented Feb. 1, 1916.

be engaged subsequently by a plunger 31 on an opposite side of a subsequent car in case such second car is to takethe main track hi stead of the switch. In other words, with the cars equipped with my attachment, the inotorman or operator on any car by pressing the proper plunger may cause the switch point to be thrown according towhether such car is to take the main track or the siding and irrespective of which arm is moved downwardly through the slots '14. The other arm will always be brought into position to be engaged by the subseable switch point associated therewith, of a bed plate extending transversely betweenthe rails andbelow the surface of the road bed, said bed plate having a pair of slots adjacent its ends extending parallel to the rails and forming concave portions of the plate, a pair of arms cooperating with the bed plate and extending upwardly in alternation through said slots, connections between said arms and the switch point and -means carried by a car adapted to engage one of said arms moving it forwardly causing the switch point thereby to be thrown and bringing the other arm into an upright position through its slot.

2. The combination with a pair of rails,

a siding and a switch point between the main rails and the siding, of a rock shaft parallel to and below the surface of the rails, a crank at one end of the rock shaft, a-rod connecting said crank to the switch point, a

pair. of shafts journaled on opposite sides of the rock shaft and at right angles thereto, gearing betweenthe rock shaft and said pair of shafts, an arm carried by the outer end of each shaft of the pair, the two arms being arranged normally at an angle to each other, and means carried by a car to engage one of the arms carrying it forwardly and down wardly causing the switch point to be thrown and the other arm to be moved in an opposite direction.

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