RAILWAY-SWITCH.

Y SPECIFICATION forming part of Letters Patent No. 292,144, datcd January 15, 1884..

' Y .pplieaiion led July 18, 1683.l (No model.)

To aZZvwhom, it may concern:

B e it known that I, EDWARD STONE, a citizen of theUnited States, residing at Cortland,

in the county of Cortland and State of New York, have invented certainnew and useful Improvements in Railway-Switches; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itV appertain's to make and use the same, reference being had to the accompanying drawings, and to the letters or iigures of reference marked thereon, which form a part of this specication.

My invention relates to railway-switches; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

The objects of the invention may briey be said to be, amon-g others, iirst, to provide a switch which shall be safe, inexpensive, simple,

and durable; second, to provide means whichV shall signal in either direction the position of the switch, and which shall be operated automatically and simultaneously with the switchoperating mechanism; and, third, to provide a novel and useful pivotal connection for the switch-rails.

To these ends the invention consists in the mechanisms fully illustrated in the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a plan view, showing the main track open in full lines and the side track open in dottedlines, parts of said gure being broken away to show the signal-connections; Fig. 2, a

, vertical section of the switch box and standard; Fig. 3, a detail showing the connections between the switch-standard, the rod which operates the switch-rails, and therods which operates the signal; and Fig. 4, a detail showing pivot-bearings of the movable switch-rails.

Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A represents the continuous rail of the main track, the other' rail, A', having thefrog J, side rails, K, andthe pivoted rail B. I have illustrated but one main track; but it vwill be understood that another is contemplated, similar, except in reverse positions,'as

ing with the frog-piece on the adjacent track, and vice versa. part of the main track when the main track is open, and has a beveled portion, b', to make a close joint with said main rail A at the bend. It is pivoted at b' bythe .joint shown in Fig. 4.,'-which will hereinafter be described.

C designates the other`switch-rail, similarly pivoted at c, and having a similar bevel, c. The freeends of these switch-rails are adjustably secured` by jam-nuts d to a threaded bar, D, which operates loosely through both the tracks A` and A, and this lrod D is connected with a disk, E, by a loosely-pivoted link, D.

The switch-rail B forms a' The disk E has a square or polygonal connecf tion with the oscillating standard Fwhich has one or more horizontal hand-levers, F, rigid therewith and working in segmental slots g, formedin the box G. This box G is stationary, and of sufdciently larger dimensions than thestandard to allow the play of a spring, H, between the two. One end of this spring is secured to the standard F and the other end to the box G, and it exerts a constant force to hold the main track open, as shown lin Fig. 1,

except when its force is overcome by the manipulation of the levers F. To the disk E, about ninety degrees distant from the connection of the link D, isopivoted a link, I, the other end of which connects with a long rod, J', which rod extends for a sufficient distance from the switch to make a signal serviceable, and is there connected by an arm, ls, with a disk, K3, on a standard, K2, working ina box, K, and carrying a signal, k, This rod J is protected by a covering, or works in a box, L, so that its free movements will not be interrupted or interfered with. It will be seen that when the main track. is open the signals are presented edgewise; but when the switch is open the signal faces one-quarter around and designates the condition ofthe track.

4Referring to Fig. 4, the stationary tracks which connect with the switch-tracks are each provided with a portion, in, which extends under the pivotal ends of the switch-tracks, andV `joint.

these portions m are each provided with concave sockets or bearings a. The switch-rails are cut away to correspond with the projections my, and have cach a convex portion, o, which operates in the sockets n. The chair P at this joint is made suiiiciently Haring .at one end to admit the necessary oscillations of the switch-rails, as described; and I attach much importance to thc construction of this pivot or single rods Without a spring, these modifications being considered equivalents.

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

I. In combination with the rails having projections m with sockets u, the switch-rails B and C, having cut-away portions and convex bearings o, and the chair I?, having Haring mouth, as set forth, for the purposes specied.

2. In combination with the switch-rails B and C, pivoted, as shown, to the rails A K, the standard F, box G, spring H, and connections E, D, and D', as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
