SWITCH MECHANISM.

To (LZZ'UJILO/ll lid mm concern: 1

Be it known t at I, Nan. E. SALSIOH, a citizen oi the United States, and, resident of Bethlehem, county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Switch Mechanism, of which the following is a specilication.

The present invention relates to switch stands and more particularly to means to actuate the signal usually employed to indicate the position of the switch.

Signals of the usual type associated 'Wltll switch stands are moved through an angle of 90 when the switch is thrown. Some switch throwing mechanisms however do not have any member which moves through exactly 90, and the present invention is directed to provision of means for actuating a signal employed. with a mechanism oi. the latter type.

The objects and features of novelty of the invention will be apparent from the description taken in connection with the drawings, in which:

Figure 1 is a top plan view of a switch stand having a signal disposed and actuated according to the present invention;

Fig. 2 is a view similar to Fig. 1 illustratin g the positions of the parts at the other end of the throw of the switch, and

Fig. 3 is a sectional elevation taken substantially on the broken line 33 of Fig. 1.

Referring to the drawings the switch stand with which the present invention is shown is that disclosed in my Patent No. 1,303,967 granted May 20, 1919. this switch stand comprises a base 10 adapted to be secured to a pair of adjacent ties 1]. and having an upstanding post 12 carrying a rotatable member 13. This rotatable member has two arms, one of which, indicated at 14, is connected to the switch by a rod 15. The other arm, indicated at 16, is formed witha curved slot 17 in which operates the block 18 pivotally carried by the hand operating lever 19. In throwing the switch the hand lever 19 is moved from the position shown in Fig. 1. to that shown in Fig. 2, that is, through an angle of substantially 180. This movement, through the block and slot connection, turns the member 13 through an angle a (Fig. 1). It will be observed that this angle a. is less Specification of Letters Patent.

than 90 and hence the signal cannot be di- .rie's the signal, this post being rotatably mounted in the bore 21 and held against downward movement by means such as the collar 23. Post 22 projects slightly below the arm 20 and is formed with a transverse aperture 2 1. A link 25 is slidably disposed in the aperture 24: and has an end 26 bent downward and fitted in a recess 27 in the base 10 of the switch stand. As shown the recess 27 is intermediate the axes of the signal and the member 18. Hence as the arm 20 swings through the angle a, the signal will turn through a different angle indicated. at b, the location of the recess 27 being such that the signal will turn through substantially 90 in the present embodiment.

It will be observed that the above described means provides a very simple mechanism for turning a signal, where it is not possible to obtain the desired movement by directly securing the signal to a member of the switch stand. Furthermore, the link 25 is disposed. under the arm 20 and is always covered thereby, thus protecting the link from injury. If desired the post 22 may be provided. with an. aperture 28 disposed at right angles to the aperture 24 so that the post may be interchangeably used with a switch stand on either side of the track.

Although a specific embodiment of the invention has been described in detail, it is to be understood that the invention is not thus limited but includes modifications and changes which come within the scope of the appended claims.

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

1. The combination with a switch stand, of an arm pivotally mounted at one end and having a rotatably mounted signal at the other, means connecting said arm and the switch stand mechanism whereby the arm is swung when the switch is thrown, and means operated by the swinging of said arm to turn the signal.

2. The-*combination with a switch stand, of a member pivotally mounted thereon, a signal rotatably carried by said member eccentric to its pivot, means to turn the member when the switch is thrown, and means operated by the swinging of said member to turn the signal.

3. The combination with a switch, of a pivotally mounted member, a signal rotatably carried by said member eccentric to its pivot, means to turn the member when the switch is thrown, and means operated by the swinging of said member to turn the signal. at. The combination with a switch stand having a pivoted member adapted to be turned when throwing the switch; of an arm rotatable with said member, a signal pivoted on said arm eccentric to the pivot of said member, and a link pivoted intermediate the member and signal pivots and slidingly engaging the signal, whereby the signal is rotated when the member is turned.

'5. The combination with a switch stand having a pivoted member adapted to be turned when throwing, the switch; of an arm rotatable with said member, a signal post pivoted on said arm eccentric to the pivot of said member, and a link disposed under said arm pivoted to the stand intermediate the member and signal pivots and slidingly engaging said post, whereby the signal is rotated when the member is turned.

6. In a switch stand having a member rotatable through an angle of less than 90 when the switch is thrown, a signal rotata; bly carried by said member, and means actuated by the movement of said member in throwing the switch to turn the signal through substantially 90.

7. In a switch stand having a switch operating member pivoted to swing through a definite angle when the switch is thrown, a signal rotatably carried by said member, and means actuated by the movement of said member in throwing the switch to turn the signal through a different angle than the member.

In testimony whereof I affix my signature.
