PERKINS II. DE ROCIIEMONT, OF CHATTANOOGA, TENNESSEE, ASSIGNOR OF ONE-HALF TO CHARLES HERRON, OF SAME PLACE.

RAILWAY- SPECIFICATION forming part of Letters Patent No. 674,535, dated May 21, 1901.

Application filed March 19, 1901.

To all whom it may concern.-

Be it known that I, PERKINS H. DE ROCHE- MONT, a citizen of the United States, residing at Chattanooga, Tennessee, have invented certain newand useful Improvementsin Railway- Switches, of which the following is a specification.

My invention relates to improvements in railway-switches; and the object of the into vention is to provide a sim ple and efficient arrangement for station -work by which the main-line switch,the second-track switch,and the derail may all be operated from the main switch without the loss of time ordinarily required by the switch man in passing back and forth between the switches.

The invention is illustrated in the accompanying drawings, in which Figure l is a plan view showing the relative arrangement of the tracks and switches. Fig. 2 is a sectional elevation on line 2 2 of Fig. 1. Fig. 3 is a detail showing the levers in a raised position. Fig. 4 is an elevation of the switch-stand looking from the track.

In the drawings, (t represents the main line, having switch-rails a; c, the second track, having switch-rails c, and b the third track, having derailing switch-rail I). These switchrails are adapted to be thrown, respectively, by switch-rods 50, x and at, connected to crank-arms 3 3 and y, as shown in Fig. l.

I have designated the switches as A, C, and B, and it will be understood that switch A, which is the main switch, is adapted to be operated without affecting either of switches B and C, the mechanism by which this is rendered possible being hereinafter described in detail.

Inorder that the switchman stationed at A may, when desired, operate both switches B and C simultaneously without leaving his post at switch A, I provide a rod W, connected to a crank-arm a at switch A, to a crankarm 0 at switch C, and to a crank-arm b at switchB. The relative arrangement of these crank-arms and the arms y, g and y is shown in Fig. 1 and, as will be observed, is such that when switch A is operated in the direction of the arrow, the attachment being connected in the manner hereinafter clescribed, the movement of the rod W in the di- Serial No. 51,839. (No model.)

rection of the arrow adjacent thereto will move the arms 11 and y in the direction indicated by the adjacent arrows, throwing the corresponding switch-rails in the position indicated bydotted lines.

In order to provide for switch A being operated alone or simultaneously with switches. l3 and C in a simple and etficient manner, I provide the construction shown in Figs. 2, 3, and 4. A suitable stand D is provided, in which is 'journaled a vertical rod d, which carries at its lower end the crank-arm y, before referred to, which operates the rod 41;. This rod is turned or rotated by a handle E, having a portion a rigidly secured to the rod above the stand and having a hinged and slotted handle portion 6' adapted to be turned down into engagement with the staple e for locking the switch. A loop a having its arms loosely engaging the vertical rod, forms the crank-arm indicated in Fig. l by said reference-letter. To the upper arm a of said loop is hinged a short arm F, which is designed when in ahorizontal positiomas shown in Fig. 2, to engage the rigid portion e of lever or handle E, so that both must move together. It is also capable of being swung into a vertical position, as indicated in full lines in Fig. 3, at which time it is disengaged from handle E and switch Ais free to be operated alone.

A hinged handle portion F is capable of being swung down into the position shown in full lines in Fig. 2 to engage the staple for looking switches B and C.

While I have shown a rigid rod as forming the connection between the switches A, B, and C, it will be understood that I do notlimit myself in this respect.

Having thus described my invention, what I claim is 1. In combination, the main line, a side track with a main switch connecting the two, a second side track, a switch connecting the 95 second side track with the first side track, and connections from the main switch to the second switch whereby both switches may be simnltaneouslyoperated from the main-switch stand, substantially as described.

2. In combination, the main line, a side track with a main switch connecting the two,

a second side track, a switch connecting the second side track with the first side track, a derailing-rail in said second side track, and connections from the main switch to the second switch and derailing-rail whereby both switches and third rail may be simultaneously operated from the main -switch stand, substantially as described.

3. In combination, a main switch, a second switch and a derailing-rail, operating connections between said second switch and derail-- switch and a derailing-rail, operating connec-- tions between said second switch and derailing-rail, said connections extending to the main switch and means at the main switch whereby said connections may be operated simultaneously with the main switch or disconnected and the main switch operated independently, said means comprising a vertical shaft having a crank-arm connected with the main switch, a. second crank-arm pivotally con nected with the first and means whereby said second arm may be caused to move with said vertical shaft, substantially as described.

5. In combination, a stand, a vertical shaft having a switch-operating crank-arm atits lower end, a crank-arm comprising a rod having angnlarly-bent ends pivotally engaging the vertical shaft, said second crank-arm being adapted to operate a second switch, a pi voted handle connected with the shaft and a second pivoted handle connected with the second crank-arm, substantially as described.

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