} SPECIFICATION forming part of Letters Patent No. 724,656, dated April '7, 1903. Application filed May 29,1902. Smrial No. 109,411. mamas.)

To all whom it may concern:

Be it known that I, ARTHUR B. BELLOWS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered In the accompanying drawings, forming a;

part of this specification, Figure 1 is a top plan view of my improved switch-stand. Fig. 2 is a sectional elevation of the same on a plane indicated by the line II II, Fig. 1. Fig. 3 is a side elevation showing the operating-lever in mid-position. Fig. 4 is a sectional view of the lock mechanism on a plane indicated by the line IV 1V, Fig. 3. Fig. 5 is a top plan View of a modification of the lock mechanism, and Fig. 6 is a sectional view of the same.

In the practice of my invention I employ a case or shell consisting of the upper and lower parts 1 and 2, which are adapted to be secured together by suitable bolts and to adjacent cross-ties or other foundation by spikes or other suitable means. It is preferred that the upper portion of the case or shell should overlap the lower portion, as shown in Fig. 2, and that the securing-spikes should pass through suitable notches formed in the edges of the overlapping portions of the upper portion of the case or shell. A vertical shaft 3 has its lower end journaled'in suitable bearings 4, formed in the lower portion 2 of the case or shell, and. saidshaft projecting up through the upper portion of the case or shell has a bearing 5 formed therein. An arm 6 is formed on or secured to the vertical shaft and is provided with a pin 7, engaging a slot formed in a transverse enlargement 8 in the switch-rod 9, so that by rotation of the vertical shaft a longitudinal back-and-forth movement is imparted to the switch-rod. Itis preferred in order to prevent any rotation of the switch-rod or shaft that a bearing 10 for the lateral extension of the switch-rod should be formed in the vertical side of the case or shell, as clearly shownin Fig. 2. A yoke 11, provided at its outer end with a socket, is pivotally connected to the vertical rod orshaftjust.

above or'outside of the upper portion of the case or sl1ell, and a block 12, provided with a projection or pin adapted to enter the socket in the yoke, is secured to the operating-lever 13, which, as shown, is pivotally mounted, preferably, between lugs 14, formed on the case or shell, in such manner that the plane of movement of the operating-lever will be at right angles to the switch-rod, and consequently parallel or substantially parallel with the rails of the track. As is customary in this form or style of switch-stand, the oper-- ating-lever is moved through an arc of one hundred and eighty degrees and is designed when in its normal positions to lie upon or closely adjacent to the surface of the ground. When the operating-lever is shifted from one position to the opposite, the'block 12 is carried through an arc whose axis will coincide with the axisof the pi vot-pin of the lever and will carry with it the yoke 11, the pin-andsocket connection between the yoke and block permitting a rotation of the block relative to the yoke during this movement. The yoke in its movement will describe the surface of a half-cone, its pivotal connection with a verti cal shaft or pin permitting such movement of the yoke.

In order to lock the switch-rod in its diflerent positions, a pin 15 is arranged in the lat: eral extension 16 of the upper portion of the case or shell and is adapted to enter transverse holes in the switch-rod in its difierent normal'positions. In the construction shown in Figs. 3 and tthis pin is loosely connected to a lever 17, pivotally mounted on lugs 18 and provided with a foot-plate whereby the pin may be raised out of engagement with the switch-rod. The opposite end of'the lever is provided with a weight 19 toreturn the lever to normal position, and when in normal in position. In Figs. 5 and 6 the pin is connected to a block or weight 19, which is adapted to be raised by the lever 17 carrying the foot-piece, the lever projecting under the block. The block is provided with a laterally-projecting arm 22, having a lug 23, projecting alongside of the lug 24 on the extension of the case or shell, and the latter lug also bearing along its opposite edge against the block. The arm extending from the block is provided with an opening registering with an opening in the case or shell, so that the block and pin may be looked as against vertical movement when desired. It will be observed that the movement of the operatinglever is in a vertical plane parallel or substantially parallel with the rails of the track, so that the operator moving along the track will not have to change his direction of movement to shift the switch, but has only to stoop down and pull the lever over, and, further, while shifting the'lever the operator does not have to bring any portion of his body in dangerous proximity to the track.

I claim herein as my invention- 1. A switch-stand having in combination, a case or shell, a vertical shaft having bearings in the case or shell and provided with an arm, a switch-bar longitudinally movable in hearings in the case or shell and having a sliding connection with the arm on the shaft, a lever pivotally mounted in a plane at right angles to the switch-bar and an arm pivotally connected at its ends to the shaft and lever, substantially as set forth.

2. A switch-stand having in combination, a case or shell, a vertical shaft having boarings in the case or shell and provided with an arm, a switch-bar longitudinally movable in bearings in the case or shell and provided with a slot for the reception of a pin on the shaftarm, a lever movable in a single plane at right angles to the switch-bar and a loose connection between the lever and shaft, substantially as set forth.

3. A switch-stand having in combination a vertical shaft provided with an arm, a switchbar provided with a transverse slot for the reception of a pin on the shaft-arm, a lever movable in a plane at right angles to the switchbar, a yoke pivotally connected to the shaft and a block connected to the lever and hav ing a rotatable connection with the yoke, substantially as set forth.

4. A switch-stand having in combination a switch-operating lever, a switch-bar operating connections between the lever and switchbar, a weighted locking-pin adapted to engage the switch-bar and lever for shifting the pin, substantially as set forth.

In testimony whereof I have hereunto set my hand.

ARTHUR B. BELLOWS.
