SWITCH- STAND.

Specification of Letters Patent.

Patented Nov. 23,1915.

Application filed April 19, 1915. Serial No. 22,344.

To all whom it may concern:

Be it known that I, RENE J. BRETON, a citizen of the United States, residing at Stockton, in the county of San Joaquin, State of California, have invented a new and useful Switch-Stand, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a switch stand so constructed as to prevent the operator from looking it unless it is set for the main line track, thereby reducing the risk of looking the switch in an improper position.

It will be understood by those skilled in the art that railroad regulations are such that a trainman very seldom leaves a switch unlocked when through using it, stringent penalties being provided for the failure to lock the switch in the position for the main line track. However, the switch stand may not always be working easily and in the haste of locking the switch and running to catch the train it may be possible for the trainman with the ordinary switch to lock it in one of two positions and if the light is out, it is not possible for him to tell at a distance whether the switch is set for the main line track or for the turn out unless he goes to the track and examines the switch points.

It will also be understood that it is necessary to provide some means to hold the switch points in one position or the other during the time the train is passing thereover to prevent the switch points from working out of their proper position and thereby permitting the car wheels to pass on to the ground, so that the object of this invention is to provide means whereby the switch may be secured in either position, but can be locked in only one position thereby enabling the trainman to make sure that if he remembers locking the switch that it is in the proper position.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof.

Figure 1 is a perspective view of the complete switch stand, Fig. 2 is a plan view of the switch stand on a smaller scale, showing the tracks at the side of the same, and Fig. 3 is a vertical sectional view through a portion of the switch stand illustrating the difan extension 10 passing into a hole in the base 1 and an arm 11 for the operation of theswitch rod 12, the latter rod extending to the switch points 13 and 1 1.

The rod 9 carries a target 15 and lamp 16 while adjacent the top plate 5 there is a heavy casting 17 riveted to the rod 9 and having a slot formed therein, within which slot the lever 8 is pivoted on the pin 18. The lever has a portion at the top provided With one large hole 19 and one small hole 20.

At the side of the switch stand a padlock 21 is hung on a chain 22 while at the other side a hook 23 is hung on a chain 24. The notch 6 is deeper than the notch 7 and allows the lever 8 to fall down into the position shown in solid lines in Fig. 3, thereby exposing the large hole 19 so that the padlock hasp can be passed therethrough. When the switch is to be turned the lever 8 is lifted out of the notch 6 and the rod 9 is twisted around until the lever can fall into the notch 7, but the latter notch is so shallow that only the small hole 20 projects out from the casting 17. This hole may be used with the hook to prevent the train going in the tracks 25 and 26 from shaking the switch points out of their proper position, but the hole is not large enough to receive the hasp of the padlock so that when the trainman returns to the switch stand to throw the switch over he can only insert the padlock in the lever when the switch stand has been set to the proper position as will occur when the switch is set for the main line position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as fol.- lows, modifications within the scope of the claims being expressly reserved:

1. A switch stand having a deep and a shallow detent, a switch operating rod, a lever pivoted to the switch operating rod and adapted to be passed into one of the detents or the other when the switch points are in diiferent positions, and a cover for the switch operating lever to prevent the padlock from being inserted in said lever when the switch points have been turned for the branch line track.

2. A switch stand having a deep and a shallow detent, switch points an operating rod pivoted to the switch stand; a lever pivoted to said rod and having a portion thereof provided'with a large and a small opening, the large opening adapted to receive a padlock hasp when the switch is turned for 'the main line track and the small opening capable of receiving a hook smaller than the padlock hasp when the switch is turned for the branch line track and the switch operating lever in the shallow detent. I

r 3. A switch stand having a deep and a shallow detent, a padlock connected to the stand on one side thereof, a hook connected to the stand on the other side thereof, a switch operating rod pivoted to the stand, a lever pivoted to said switch operating rod and adapted to be placed at will in either the deep or the shallow detent, said lever having a large hole to receive the padlock hasp when placed in the deep detent and having a small hole to receive the hook when the lever is placed in the shallow detent.

In testimony whereof I have hereunto set my hand this 13th day of April A. D. 1915, in the presence of the two subscribed witnesses.
