SWITCH STAND.

T all 'whom z't may concern:

2 Be it known that I, Ronnnr T; BUTLER, a'

citizenofthe United States, residing at v Flushing, in the county of Belmont and State c of Ohio, have lnvented certaln new and useful' Improvements in Switch Stands; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in'the the same; i v This invention relates to a switch stand, and the object is to provide a device especially adapted for use in mines, where the space is limited, and where a switch stand which may readily be made-'byany skilled 'mechanic,.will serve the purpose. f A A further object istol provide switch controlling mechanism which may be mounted so in such position that the stand will be parallel with the rails, instead of being mounted transversely thereof, in accordance with the usual practice.

A still further object is to provide a stand per so which may be of arch construction, the arch mounting a pivoted arm, extending transversely of the base portion and being 10 art towhich it appertains to make and use resiliently supported at one end, -with an operating lever pivoted to the upper portion or crown of the arch and having pivotal connection with a second lever which in turn is pivotally mounted on the transverse arm, the second lever directly or indirectly con trolling the usual rod connected with the switch rails.

A still further object is to provide a particular form of connection between the levers mounted on the stand, and the rod directly connected with the rails, whereby the stand may be mounted in a position parallel with the rails, instead of transversely thereof. 7

With the foregoing and other objects in view, the invention consists in the novel con- Figure 1 is a perspective view of the switchv stand per se, but showing also an angle lever, for connectionwlth a swltch rod, not shown,

scribed below.

struction, combination, and arrangement of Figure 2'is a top plan view showing the stand mounted parallel withga section of track, adjacent to the switch rails,

Figure 3 is a detail of construction de- The switch stand includes an arch shaped frame comprising the outer sides 10 and ;12.

The arch is supported upon foot members 15' and 16 1nounted'on bars 17, and 18'which in turn are connected with the ties or sleepersj19 and 20, extending a considerable distance beyond the tracks per se, in accordance with the usual practice. The stand may be formed of angle iron, and being simple in construction, may be made by an expert mechanic, such as a blacksmith usually employed for work at the mines. The foot members may be formed by securing an addi tionalpiece of angle iron to each side ofthe main frame, or the frame may be constructed of two complete strips of angle iron.

A transverse bar 21 is pivoted at 22 to one side member of the frame, the opposite end of the bar being apertured and accommodating a vertical rod 23 which passes through the aperture and through a bracket 24 connected with the frame. A spring 25 encircles the rod below the transverse bar,and the spring is retained bya nut 26. While a compression spring has been shown in the drawings, nofllimitation in this particular type of connection is intended, the essential point being that a resilient mounting be pro vided.

An operating or hand lever 28 is pivoted at 29 on the frame and has pivotal connection at 30 with a second lever 31, the latter, in turn, being pivoted at 32 to the transverse bar 21. The length of the levers-is such, between the pivotal points, that the lever 28 when thrown in either direction will necessarily depress the pivoted arm 21, the latter yielding under the action of the spring.

The switch throwing rod 34 is pivotally connected with an angle lever 36, mounted at 37 on one of the bars extending transversely of the tie. The other end of the angle lever is connected by link 38 with the lower end of the lever 31, the connection bemoves in a vertical longitudinal plane, permitting the switch stand to be mounted parallel with the track.

Having thus described the invention, what I claim is i 1. ln a device of the class described, a frame, an operating lever pivoted thereon, a

second lever pivotally connected with the operating lever, an arm pivotally connected at one end with the frame, the opposite end of the arm being resiliently held in an approximately horizontal position, means for pivotally connecting the second lever with "saidarm, a switch rod, and means for connecting the latter with the lower ,end ofvthe second lever.

2. In a device of the class described,a frame, an arm pivotally mounted on the frame, one end of the arm being movable in a vertical plane, means for resiliently mounting the movable end,; an operating lever pivoted to the upper portion of the frame, a second lever pivotally connected with the operating'lever and with the aforesaid arm, a switch rod movable in a horizontal plane, the aforesaid levers moving in a vertical plane, and means connected with the lower end of the second lever for transmitting the movement of that lever to the switch rod; 7

frame,aplurality of levers, one of the levers beingvpivotally connected with the frame,

and the levers being pivotally connected with each other, a switch rod, an angle lever pivotally connected therewith, said rod and lever being movable in a. horizontal plane and the levers being movable in the vertical plane, and a link pivotally connecting the angle lever with one of the levers first named.
