SELECTOR FOR RAILWAY SIGNALING APPARATUSQ SPECIFICATION forming part of Letters Patent No. 707,180, dated August 19, 1902.

Application filed November 10, 1900. Serial No. 36,019. (No model.)

To aZZ whom/it may concern:

. Be it known that I, J OHND. TAYLOR, a citizen of the United States, residing at Buffalo,-

New York, have invented certain new and useful Improvements in Selectors for Railway Signaling Apparatus, of which the fol-.

erating such signals; r

" My invention is further adapted to andis an improvement 'upon the signal apparatus heretofore patented to me on the 4th day of February, 1896,-N0. 554,097, and the 7th day The object of my invention is to provide means whereby either one of any number of signal-arms or indicator-disks may be operated by the same gearing at pleasure.

Figure 1 of the drawings is'an elevation,

partly in perspective, showing the device in the drawings and description it will be evident'to one skilled in the art how by the ad dition of similar parts the invention maybe adapted to the operation of or selection between any number of signal-arms.

1 represents a section of the signal-post carrying the signals proper and the motor and" mechanism for operating the same.

2 is a plate bolted to the post 1, having a bracket (not shown) which supports the outer end of the pin 4, which has its inner end supported in the plate 2. The pin 4; is the pivotal-snpport of the levers and the counterweight -lever. The horizontal part of the bracket-(not shown) supports the magnets. 6 represents a lever in the normal position, and 7 a second lever in the normal position, pivoted to the pin at. Each of these levers is connected to a signal-arm by connecting- rods 8 and 9, respectively; These levers take the place of the ordinary counterweight-levers. A counterweight-lever 10, to which the signalmotor. mechanism is connected by the chain 7 '11, is also pivoted to the pin 4. Each lever to which a signal-arm is connected carries a clutch 12, pivoted in any suitable wayin a fork 13, formed on .one end of the lever-bar. The clutc'h12 has a lug 14 at one end, which is adapted to engage with a cross-bar15,'c"arried at the end of the counterweight 10. This cross-bar 15 extends across all the clutches 12. The clutch 12 in the normal position extends across the poles of electromagnets 17. A motor 5, mounted upon the post 1, through gearing and a chain-sheave operates the chain 11.

When thesignal-operating motor 5 is actuated by a current, the counterweight-lever 10 is raised and the cross-bar 15 is carried downward through an arc of a circle a distance sufficient to set the signal.

The clutch or clutches 12 which are uninfluence'd by their corresponding magnets 17 hang so that their ends 14 lie without the path of the cross-bar 15 and are not engaged by 12 and the lever (6 or 7, as the case may be) to whichit is attached along with it.

'The movement of the lever (6 or 7, as the case may be) puts the signal-arm to which it is attached in the safety position. When the circuit is broken through the brake-magnets in the signal-operating machine, (not shown,) which magnets when energized hold the sigmeals in the safety position, the counterweightlever 10 falls and carries the cross-bar 15 upward. .The beveled upper edge 18 of the cross-bar 15 strikes the beveled shoulder '19 of the clutch 12, forcing the clutch back into its normal position with respect to its own lever and carries the lever back to its normal position, through which the signal-arm is re turned to normal or the danger position.

.There are as many magnets 17 used as there are signal-arms to be operated,'and an electrical conductor leads from a controlling-lever in the cabin to one terminal of the magnets 17. The remaining terminals of all the troller is in all respects like that used in connection with single signals. From the other terminal of the motor a common return-conductor-leads back to the cabin. The controlling-levers in the cabin are of course interlocked so that only one lever can be reversed at a time, and consequently only one of these circuits can be completed and only one of the magnets 17 energized at a time.

Having thus described my invention, What I claim is- 1. The combination with an operating-circuit, a signal-motor, gearing, and a plurality of signals, of a counterweight-lever, a set of signal-levers actuating said signals, mechanism for engaging any one of said signal-levers with said counterweight-lever, and a set of magnets to actuate said mechanism engaging said signal-levers with said counterweightlever, substantially as and for the purposes set forth.

2. The combination with an operating-circuit, a signal-motor, gearing, and a plurality of signals, of a counterweight-lever, signallevers and magnets in number corresponding to and in operation actuating said signals, mechanism for engaging said counterweightlever with any one of said signal-levers actuated by said magnets, and means for closing any one of said magnets in the motor-circuit, substantially as and for the purposes set forth.

3. The combination With an operating-circuit, a signal-motor, gearing, and a plurality of signals, of a counterweight-lever actuated by said motor, signal-levers oorrespondingin nu In her to and actuating said signals, clutches pivoted to said signal-levers, a pallet secured to said counterweight-lever capable of engaging any one of said clutches, magnets corresponding in number to said signals, means for closing any one of said magnets in the motor-circuit to throw its clutch into engagement with said pallet, substantially as and for the purposes set forth.

4. The combination with an operating-circuit, a signal-motor, gearing, and a plurality of signals, of a counterweight-lever actuated by said motor, signal-levers corresponding in number to and actuating said signals, a clutch pivoted to said signal-levers, a pallet secured to said counterweight-lever capable of engaging any one of said clutches, magnets corresponding in number to said signals, means for closing any one of said magnets in the motor-circuit to throw its clutch into engagement with said pallet, and means for disengaging said clutch from said pallet in the movement of the counterweight-lever to normal, substantially as and for the purposes set forth.

5. In combination with a signal-motor, an operating-circuit, a plurality of signals, a counterweight-lever, gearing connecting said counterweight-lever and said motor, signallevers corresponding in number to the number of said signals, a corresponding number of magnets, clutches on said levers, a pallet on said counterweight-lever to engage said clutches, said magnets having one terminal connected with controlling-levers corresponding in number to said magnets, and the remaining terminals of said magnets being connected to one terminal of the signal-motor, to close any one of said magnets in the operating-circuit and throw its clutch into engagement with the counterweight-lever coincident with the energizing of the motor, substantially as and for the purposes set forth.

6. The herein-described system of operating a plurality of electric signals by the action of one signal-motor and one train of gearing, consisting of said motor and gearing and motor-circuit and a plurality of signals, of a series of magnets equal in number to said signals, controlling-levers for operating said signals connected with one terminal of each of said magnets, the other terminals of said magnets connecting With said motor, a set of levers connected to said signals, a counterweight-lever actuated by said motor, and a clutch on each one of said signal-levers to engage said counterweight-lever by energizing one of said magnets coincident with the closing of the circuit through the motor, substantially as and for the purposes set forth.

7. The herein-described system of electric railway-sign als consisting of a plurality of signals, a single motor and mechanism connecting it with a single counterweight-lever, a counterweight-lever, signal-levers connected with said signals, a set of magnets corresponding in number to said signals, clutches carried by said signal-levers and adapted to engage With said counterweight-lever, means for energizing said magnets for throwing said signal-levers into engagement with said counterweight-lever, and means for mechanically disengaging said clutches on the return of the signal to normal, substantially as and for the purposes set forth.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.
