CONTROLLINGIDEVIGEFOR RAILWAY-SIGNALS AND THE LIKE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, WILLIAM REID, a subject of the King of Great Britain and Ireland, residing at Caulfield, in the State of Victoria, Commonwealth of Australia,

. have inventeda new and useful Improved Controlling Device for Railway-Signals and the Like, of which the following is a specification. This invention relates to an improved controlling device for railway signals and the like and refers more especially to a mechanically controlled device by which certain semaphoreisignals may be controlled from two separate stations.

This invention is capable of many different modifications injuse, such as for example in such installations in which two semaphores are arranged upon the same post, each being operated from a different source and in which the operation of one is controlled by the other, or where one sema- 1 phore is controlled by two separate levers operated from different sources.

The object of this invention is to provide I a'controlling apparatus of simple and cheap construction, whichmay be easily affixed to the signal posts themselves and connected to the ordinary mechanism as at present in use, andproviding the control above referred to. I accomplish this object by providing a controlling apparatus which consists of a swinging'pendulum lever having a shouldered recess that engage's an arm connected to one operating rod, the said swinging lever engaging at its lower-end a 7 slot or recess upon a hinged trigger which is operated by a rod, connected to the other lever. 40.

In order that my invention may be the better understood I will now proceed to dependulum lever B which is suitably enthe shouldered recess B of the swinging pendulum lever'B. The rod E connects the lever C with an operating weighted lever F. The swinging pendulum lever B is provided with a roller B at its lower end, which engages a recess G upon the under side of a weightedtriggereG yvhich is pivoted upon a lug A of the casing A. 'This pivoted trigger G is operated by a rod H which is connected as hereinafter described.

It will be seen thatas long as the tripping trigger G is in the position shown in Fig. 1, the swinging pendulum lever B securely'locks the end of thelever C, the re-. cess B acting as' afulcrum for the same,

allowing the'rod D to operate the sema Patented May 28,1912.

the operation 'of the rod E is ineffective so far as manipulating the semaphore is concerned. I

When the'controller is applied to a signal posthaving one semaphore, the connection is as shown-in Figs. 1 and'2. In this case the rod I-I operating the trigger G is connected to a second weighted lever J, which is connected by a wire J to another signal box. When the two levers F and J are in the horizontal position as shown in Fig. 1 that is to say, when tension is applied to their respective wires F and J the trigger G is in its downward position and the swinging pendulum B locksthe inner end of the lever C within its recess B. Consequently the operation of the lever F as actuated by the wire F is such that the semaphore cannot be operated until the lever J through the rod H releases the trigger G into the position shown in Fig. 1.

When the lever J is released as shown in Fig. 2 it will be seen that the rod H raises the trigger G and allows the swinging pendulum lever B to move across thereby releasing the inner end of the rod C from the shouldered recess B so that the lever F is operated through the wire F the lever C (not now being fulcrumed at its inner end) the manipulation of the semaphore through the rod D is ineffective. It will be seen therefore that the semaphore cannot be manipulated until the lever J has been operated from its respective signal box while furthermore by releasing the tension upon the wire F the semaphore connected to the rod D may move back into the danger position by its counterweight, irrespective of the operation of the lever J.

When the controller is adapted for use with a two-semaphore signal post the connection is as shown in Figs. 3 and at. In this case the upper semaphore D which controls the track is connected by means of the rod D directly to the operating lever F, which is connected by a wire F to one signal box. The other semaphore M is connected by means of the rod M to the lever C which projects into the controller casing A the internal arrangements of which are the same as shown in Figs. 1 and 2. To this lever C is pivoted a connecting rod E which leads to the other weighted lever J which is connected by a wire J to another signal box. The rod H which operates the trigger G within the controller A is connected to the weighted lever F upon the side opposite to its weight that is to say upon the same side as the operating wire F. The operation of this signal post and controller is such that the upper controlling signal 1) is operated directly by the lever F as pulled by the wire F from the signal box while at the same time the lever H is withdrawn from the trigger G by which the lower end of the swinging pendulum lever B is locked correspondingly locking the inner end of the lever C within the shouldered recess B, so that the operation of the weighted lever J as manipulated from its signal box through the wire J imparts movement through the rod E to the lever C which being tulcrumed at its inner end within the shouldered recess B moves the semaphore h into the 01 1" position as shown in Fig. 4-. It will be seen therefore that the semaphore M can only be operated after the semaphore D while at the same time unless the semaphore D is pulled into the ofi' position, it is impossible to operate the semaphore M as any external tension placed upon the wire J would not operate the semaphore M.

The swinging pendulum lever B is also provided with a lock P, which projects through a slot in the casing A, having a hole P at its outer end by which the same may be locked at any time by means of a padlock or other convenient locking device.

I claim 1. A cont-rolling device for railway-signals and the like, comprising a casing, a swinging pendulum-lever within said casing, said lever having a shouldered recess, a lever engaging said recess, a semaphore, a rod connecting the lever with said semaphore, a weighted operating lever, a rod connecting the operating lever with *the semaphore operating lever at or about its center, a trigger engaging the lower end of the pendulum-lever, and having a recess, a rod engaging said trigger, and a weighted auxiliary lever for actuating said triggerrod.

2. In a controlling device for railway-signals and the like, the combination of a casing, a swinging pendulum-lever within said casing, said lever having a shouldered recess, a lever projecting through a slot in the casing, a semaphore, a rod connecting the outer end of the lever with the semaphore, a weighted operating lever, a rod connecting the lever with the operating lever, a trigger having a recess engaging the lower end of the pendulum-lever, a rod operating said trigger, and means for actuating said trigger rod.

3. In a controlling device for railway-- signals and the like, the combination of a casing, a swinging pendulum-lever in said casing having a shouldered recess, a lever engaging said recess, a semaphore, a rod connecting the outer end of said lever with the semaphore, a weighted operating lever, a rod connecting the semaphore-operating lever with the said weighted lever, a trigger having a recess engaging the lower end of the pendulum-lever, a rod acting upon said trigger and an independently operated weighted lever actuating said trigger-rod.

4. In a controlling device for railwaysignals and the like, the combination of a casing, a swinging pendulum-lever in said casing, said lever being provided with a shouldered recess, a lever fulcrumed at its inner end in said shouldered recess, a semaphore, a rod pivoted at its lower end with said lever and at its upper end with the semaphore, a trigger having a recess engaging the lower end of the pendulumlever, a rod for operating the trigger, and means for locking the pendulum-lever to the casing.

5. In a controlling device for railwaysignals and the like, the combination of a casing, a swinging pendulum-lever in said casing, said lever having a shouldered recess, a lever fulcrumed at its inner end in said shouldered recess, a semaphore, an auxiliary semaphore, two weighted operating levers fulcrumed below said casing, a rod connecting the casing-lever with the auxiliary semaphore, a second rod connecting the second lever with the lower operating lever, a rod connecting the firstor mainsemaphore with the upper operating-lever,
