ADELARD F. MARTEL, OF- MONTREAL, QUEBEC, CANADA, ASSIGNOR OF ONE-FOURTH TO CHARLES AUGUSTE MARTEL, OF SAME PLACE.

RAILWAY-SWITCH.

SPECIFICATION formingpart of Letters Patent No. 243,933, dated July 5, 1881.

Application filed March 2, 1881. (No model.)

To all whom it may concern Be it known that I, ADELARD FRANK MAR- TEL, of the city of Montreal, in the county of Hochelaga, in the Province of Quebec, Canada, railway-conductor, have invented new and useful Improvements on Railway-Switches; and I do hereby declare that the following specification is a full, clear, and exact description of the same.

My invention relates to railway-switches; and it consists in a point or tongue pivoted at the end of the inner siding-rail and adapted to be swung against the inner main rail, and a lever connected with said point or tongue, and having two arms, to one of which a weight is applied to hold the point ortongne normally away from the main rail, and to automatically open the switch after the passage of a train to or from the siding, while the other arm is furnished with a wire rope, or its equivalent, by which the switch may be closed by the attendant in the switch-house or at a distance.

Figure 1 is an elevation of my invention. Fig. 2 is a plan of my invention.

A is a movable point or tongue hinged to the inner siding-rail and connected with the switch-rod L, so as to be controlled by the switch-lever M through the weight D on lever N.

B is the fixed point of outer rail of main line I, and is made so as to be a continuation of the outer rail, although not connected, and allowing the flanges of the wheels to pass between it and the outer rail, 0, of the siding, when the switch is put into action and the point A brought into contact with the inner rail, P, of the main line, to enable the train to take the siding.

C is the switch-post, to which the switchlever M is pivoted by a bolt through it, so as to secure the necessary leverage, and provided with the projection N to hold weight D.

D is a weight placed on projection N, so as to keep the movable point A always open, so that the main line is clear at all times when no train is taking the siding.

E is the joint of the movable point A.

F is the frog attaching the inner rail, R, of the siding with the outer rail, S, of the main line.

G is a guard-rail for the purpose of protecting the openings in the rails at the frog-angle.

H is a guard-rail for the same purpose. I is the main line.

K is the siding.

L is the switch-rod, connected with the inner side of movable point A to keep it detached from the inner rail, P.

M is the switching-lever, having two projec- 6o tions, N and N, to which are attached, respectively, the weight D and the wire rope S, which may be placed in a tube or otherwise protected and attached in the station to a lever, so as to allow the switch to be manipulated inside.

O is the outer rail of the siding.

P is the inner rail of the main line.

B is the inner rail of the siding.

S is the outer rail of the main line.

S is the wire rope from the office to the switching-levers N.

The mode of working this switch is very simple. The main lineis always clear except during the time of switching 01f a train, and a train coming from either end of the line is switched onto the siding by moving the point A close to the inner rail, P, by rope S and switching-lever M, which returns to its first position on loosening the rope S by weight D on projection N.

1 am aware that a pivoted tongue held away from the main rail by means of a weight or spring to keep the main line normally open is not, broadly, new; but 1 am not aware that any one has hitherto constructed and arranged 8 5 the parts in the manner herein set forth, or that means have been provided for operating the switch from within the switch-house or from a distance.

What I claim as my invention is--- 0 1. In a railway switching apparatus, the combination and arrangement of inner rail,

P, of the main line, outer rail, S, of the main line, outer rail, 0, of the siding, inner rail, It, of the siding, frog F, guard-rails G and H, 5 stationary point B, moving point A, rod L,

switching-lever M, projections N and N, post 1 its equiva1ent,-and connected with the tongue 0, weight D, and rope S, the whole arranged A, as set forth.

as descfibed, and for the purposes set forth.

2. In combination with the main and siding l 5 rails, arranged substantially as shown and de- Witnesses:

scribed, the pivoted tongue A, and the Weighted T. RAJOTTE, lever M, provided with an actuating-rope, or AUG. LEVEQUE.
