SWITCH-STAND.
Specification of Letters'Patent; Patented NOV. 11, 1919.
Application filed January 30, 1919. Serial No. 274,124.
To all whom it may concern." I
'Be it known that I, SHERROD RIDDEL, a
citizen of the United States, residing at the position shown in Fig. 1. Nut is car-7 Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Switch-Stands, of which the following is a specification.
My invention relates to improvements in switches and refers more particularly to switch stands therefor.
The principal object of the invention is to provide a simple and reliable device of the foregoing character wherein the number of operating parts is reduced to the minimum, and in. which the action of the operating lever will be communicated to themovable switch tongues in a direct line by the use of a worm drive in place of the usual reciprocating levers or cog gears.
With the foregoing general objects in view, together with other objects which will hereinafter appear, my invention comprises the new and useful details of construction and arrangement, which will be herein fully described, illustrated in the annexed drawings, and pointed out more specifically in the appended claims.
In the accompanying drawings wherein the preferred embodiment of the device is shown, like reference characters refer to like or corresponding parts throughout the several views.
In the drawings Figure 1 is a vertical section of the switch stand of my invention, the view being taken crosswise of the track and in the vertical central plane of the stand. Fig. 2 is a top plan view of my stand, the lid therefor being removed for clearness of illustration. Fig. 3 is a vertical sectional view ofmy stand, the view being taken on line 33 of Fig.2.
Referring now to the drawings, numerals 1 designate the switch tongues of a switch, and 2 the bridle rod uniting said tongues. On the bridle rod I provide a downwardly extending lug 3 perforated to receive the throw rod 4: of the operating mechanism, a nut 4 being attached to the outer end of the throw rod in the usual manner. Spaced from the lug 3 I provide a second nut 6 on rod 4, and between the nut 6 and lug 3 I apply a coil expansion spring about the rod, the spring being adapted to normally force lug 3 and bridle rod-2 to'the right,
thus normally forcing the switch points into ried adjacent the outer end of rod 4: and engages the lug 3 to move the switch points in the opposite direction when the rod is so actuated.
The switch stand comprises a frame 11 which comprises three sides, the inner side being open. .Across the top is bolted a re-,
movable top plate 13. Within frame 11 a slidable block 7 is adapted to travel at right angles to the track, a pair of guides 12 being provided on the inner walls of the frame,
and coacting guide grooves on the block being positioned to register therewith. A worm 10 is provided on shaft 14, said worm meshing with teeth provided in the interior of block 7. An operating lever 15 is keyed to shaft 1% outside of the frame.
It will be readily seen that as the shaft let with worm 10 is rotated by the actuation of lever 15, the block 7 will be actuated along guides 12 in frame 11. Throw rod 4 is removably fixed to the block 7 by the provision of a depending lug 8 perforated to receive said rod, nuts 9 being provided on rod 4 on each side of lug 8 to secure the rod in fixed relation to the block.
As a means of. indicating the-condition of the switch I have provided the usual semaphore-20, the same being pivoted in the top plate 13. Between the plate 13 and the block 7 is a cam 16 fixed to the lower end of the semaphore staff 19. Cam 16 is provided with a slot 18 and an upstanding pin 17 in block 7 is adapted to register therewith. It will be seen that as the block and switch tongues readily seen" that my invention provides a simple and reliable switch stand, wherein the number of operating parts has been re- I duced tothe minimum, and in which the action of the operating lever iscommunicated to the movable switch tongues in a directdetails may be varied in many ways without departing from the spirit of the appended claims.
. Having thus describedmy'invention, what I-claim is 1. In a switch stand,
a casing, a horizontally slid-able internally threaded block in said casing, a screw-threaded shaft engaged in the threads in said block, an operating lever on said shaft, and connecting means between the block and switch points.
2. In a switch stand, a casing having three vertical walls, an internally threaded block slidable horizontally into and out of the easing, a screw-threaded shaft engaged in the threads in the block, an operating lever on said shaft, and connecting means between the block and switch points.
3. In a switch stand, a casing having three vertical walls, the opposite walls thereof having horizontal guide ways, an internally threaded slidable block having guides on its opposite faces engaging the guide ways in the casing walls, a screw-threaded shaft engaged in the threads in said block, an operating lever on said shaft, and connecting means between the block and switch points.
i. In a switch stand, a casing, a horizontally slidable internally threaded block in Copies of this patent may be obtained for said casing, an upwardly extending pin in said block, a semaphore stafi pivoted to the casing, a cam fixed to the semaphore staff to rotate therewith, a cam slot in the cam positioned to receive the pin on the block, a screw-threaded shaft engaged in the threads in said block, an operating lever on said shaft, and connecting means between the block and switch points.
5. In a switch stand, a casing, a horizontally slidable internally threaded block in' said casing, a screw threaded shaft engaged in the; threads in said block, an operating lever on said shaft, a throw rod fixed to the block, spaced-apart nuts on said rod, means between the nuts engaging the rod to the switch, and a coil spring between said means and one .of the nuts.
