RAILROAD SWITCH-S'T'AND.

SPECIFICATION forming part of Letters Patent No. 291,804, dated January 8, 1884.

Application filed March 16, 1883. (No model.)

To all whom it may concern..-

Be it known that 1, CHARLES H. TALMAGE, of Atchison, in the county of Atchison and State of Kansas, have invented anew and I mproved Railroad Switch-Stand, of which the following is a full, clear, and exact description.

My invention consists of an improved contrivance of the switch-stand for what is known as the three-throw split switch, and consisting of two switches branching off from the main track at the same place, to be operated from one and the same stand.

The improvement in the stand consists of a contrivance of gears connecting the two switchshafts with the shaft of an operatinglever by a mutilated or partly-toothed wheel, whereby the two switches may be operated by one and the same hand-lever, so as to simplify the apparatus and cheapen the cost, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 isahorizontal section of the switchstand and plan of part of the switch. Fig. 2 is a front elevation of the switch-stand, and Fig. 3 is a plan view of the switch on a reduced scale.

The shaft-s a and b are geared with the levershaft 0 by the wheels (I and e on them, and the wheel f on said lever-shaft, for being operated by one and the same lever, g. The wheel f is toothed in part and to such extent only that it will only turn the wheels (I and 6 one way from the starting-point-that is to say, when turned in the direction of the arrow 1, Fig. 1, and back, it will turn wheel 6 in the direction of arrow 2 and back without turning wheel (I; and when turned in the direction of arrow 3 and back it will turn wheel (Z in the direction of arrow 4 and back without turning I turned in the direct-ion of the arrow 5, drawing switch-rails a toward the switch-stand, and the train will run on the lower track or rails, 3 3, the rails b not being disturbed, and by turning the lever 9 back and then in the direction of the arrow 6 the rails a will be shifted back to the position represented in the drawings, and rails 12 will be shifted from the switch-stand, and the train will run on the upper track or rails, 1 1, all being effected by the one switch-lever.

The supporting device for the shafts a b is to consist of the two uprights h, of any suitable base, i, and having a top, j, under which the sockets 76 are provided for the upper ends of the shafts a b, and also the socket Z for the lower end of shaft 0, the latter being located below wheel f and supported by the brackets m of the uprights h. The uprights it have bearings n for the proper support of the shafts a b at their lower ends. The lever-shaft c is to have a proper extension above the lever g, for the application of a target, 0, and for the attachment of a lamp, 1).

Although I have represented the wheels d and e as being mutilated or only partly toothed, that is not an essential feature for them; but they are not required to be toothed all round. It is only the wheel f that is nec-' essarily toothed only in part.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a pair of crankshafts set at right angles to each other, and adapted to be connected to the switch-rails, and gear-wheels on said shafts,ofalever shaft provided with a mutilated gear-wheel, substantially as herein shown and described.

2. The combination, with the rails a b", of the crank-shafts a b, the wheels d e, the mutilated wheel f, and operating-lever g, substantially as herein shown and described.

3. The supporting-frame for a switch-stand, consisting of uprights h, base i, and top j, and being provided with sockets k and Z, and the shaft-bearings n, substantially as described.

CHARLES H. TALMAGE.
