Railway-Switches. No. 145,518. I Patented Dec. 16,1873.
UNITED STATES PATENT OFFICE.
EDYVARD MEROIER, OF SPRINGFIELD, MASSACHUSETTS.
IMPROVEMENT IN RAILWAY-SWITCHES.
Specification forming part of Letters Patent No. 145,518, dated December 16, 1873; application filed July 22, 1873.
To all whom it may concern:
Be it known that I, EDWARD Mnncnsn, of Springfield, Hampden county, State of Massachusetts, have invented an Improved Self- Operating Railroad-Switch, of which the following is a specification:
My invention consists in the combination and arrangement of parts whereby the train of cars will always throw the switch to connect with the main track, whether coming from off the switch to the main track or coming from either direction toward the switch when connected with a side track.
In the drawings, Figure I is a plan view of my improved switch. Fig. II is a partial side view, and Fig. III is a detail view.
In the drawing, Fig. I, the switch D is shown connected with the side track B and I will suppose the train approaching upon the main track from either direction; if from the direction indicated by the arrow marked I, a suitable projection, b, Fig. II, from the front of the train or engine, coming in contact with the hinged piece 0, the side of which extends obliquely across the track of the train, swings it out of the way, and in that action, by the connection It and crank T, partially rotates the shaft U, which rotation, by means of the eccentric W and connection R therefrom to the switch D, swings the switch to connect with the main track H. The same rotation of the shaft that accomplishes this, by means of the crank O and rod 1, swings the hinged piece V, having double-inclined surfaces, into such position that it would be cleared by the projection 12 from the train if coming toward the switch upon a track connected therewith, but would be swung aside by such projection if approaching upon a disconnected track. In the same way the train moving upon the main track, as shown in Fig. 1,1'n the direction indicated by the arrow II, would, in moving through the incline V, throw the switch D to form the connection, and at the same time swing the piece 0 so as to leave it in the proper position to be cleared by trains going in either direction upon the connected main track. Thus it will be seen that the main track will always be kept clear and continuous, automatically, to a train already upon it, and also connected to the side track from which a train is passing.
The cranks T and O are arranged upon opposite sides of the shaft U, so that the inclines O and V may be swung in opposite directions to accommodate themselves to the changed position of the switch D, and the rods h p are formed, as shown in Fig. IV, so as to have inclined surfaces 3 4:, to rise upon the shaft U and permit the pin j to play in slot it until the rod h or 1) shall have raised the pin j from a center. The eccentric when the shaft U is partially rotated, throws the switch D and when the switch D is opposite either track B or H, the eccentric is looked upon a center, so
that no force applied to the switch itself can move it from its position. The eccentric, as-
shown in the drawing, has its cover removed, which, when on, prevents the rod R from rising, and holds it in place. At one end of the shaft U is placed the handle a, by which the switch is manually thrown to connect with the side track, and which, by hearing against the tie f, holds the crank IV upon a center. Stepped in the tie f is the signal-target E, from which chains or cords m m pass to the shaft U, to which they are attached, so that the shaft, when it rotates, acts as a pulley to partially rotate the target. to expose its face to the approaching train when the main track is connected. The projection b may be arranged in front of the pilot of a locomotive, or in any other forward part of the train, so thatit may be lifted by the engine-driver when not required, or when it is desired to pass onto the side track; and it may be sleeved or otherwise constructed to rise upon and pass over the pieces 0 or V upon the beveled end 0, as shown in Fig. II, where the end 0 is shown in profile, should the projection b be left dependent.
In this self-operating switch I am able to guard against three frequent causes of acci dent, namely, from trains running onto a switch holding another train or loose cars, and from jumping the track entirely by passing off of either a side track or the main track when the switch is misplaced, as the engine-driver, if the projection b is not already down, can drop it instantly upon being apprised by the target that the switch is not in its proper place.
Now, having described my invention, what I claim is- 1. In combination with the switch D, and
with the shaft U, with crank T and eccentric W, or equivalent device for diverting motion to the switch D, the hinged piece 0, arranged and constructed to be operated substantially in the manner and for the purpose set forth.
2. In combination with the switch D, and with shaft U, with crank O and eccentric W, the double incline V, operated in the manner and for the purpose set forth.
3. In combination with the switch D, the hinged pieces 0 and V, cranks T and O, shaft U, and eccentric W and handle a, the parts being relatively arranged to operate substangially in the manner and for the purpose set orth.
4. The crank O or T upon rod U, constructed so that the inclined surfaces 3 4L bear against the crank-shaft U, to start the crank from off a center and permit the pin j to play within slot k until the center is overcome.
5. In combination with the swinging beveled inclines between the rails, the slide 1), to be raised by the inclines themselves when they are not in the position to be swung by said slide 1), as shown and described.
