To all whom it ma 1 concern.

'BCf-lll known that l, Xi'zLsox 'lowxn SnAw, a cit zen ofthe United States, residing at Los ,Angeles, inthe countyof Los Angeles and" State ot (-alil'orina, have invented anew and usefulElectric Swircli or Signal (onti'olling Apparatus; of which the following is a specification.

This invention is intended particularly for the o 'ieration of the switches ofrailways, forf example, street railways, the object of the in vention in that connection being 'to provide 'means, for operation of a switch, in opening and closing the same, by the inotorinim, without necessity ofhis leaving the car. i

The invention, in some of its features, is

also applicable for the operation of electric railway signalingzdeviees, for example, semaphores in block'signaling apparatus.

- In the accompanying drawings:Fignre 1 is a plannofa railway track atra switch or turnout, showing the swi'tcl'i operating means the'reat, :the cover of the ctfiitaining case 7 thereof being removed to show the-interior i'f j 2f5 -parts Fig. .2 is a diagrammatic section of the car, showing the contact neans thereon for controlling the operation of the switch.

Fig. 3 is a vertical sectionjof 'a ,referred-con-- struction andarrangement oft 1e switch 01)- 30,.erating means: 4 is a sectional elevation of a semaphore fora block signal provided with my invention, the controlling circuits thereof beingshown diagrammatically.

Referring to Fig. '1, 1 designates the main, track or railway line and 2a branch thereof; a movable switch orltongue 3- being provided to turn the car fromth'e main to the branch line. A, spring" 4 operates on the switch to normally-hold the sameopen, so that the car '40 will continuefon the I-main line. The switch operating means may be- 'inel'osed in a case 5 located adjacent tothe track'an'd containing a switch operating electromagnetic means or solenoid, 6- and a retaining electromagnetic means orsolenoid 7. "The armatureor core 8 of solenoid 6 is connected to.a level-9 and a link or rod 10 connects this'lever with the switch tongue 3 so that energization of solenoid 6' will, throughthe core-8,1ever 9 and rod 10, push; the s; itch ton ue to closed positionto'tu'rn the i onto t e branch 2. A looking .or retaining lever 12 is pivoted in the "case and has a hook 13: engaging with the le- "ver 9 when the latteris operated by core 8, to hold said lever in such operated position, a spring-14 acting on-the retaining lever 12 STAT A with :SHAW, or 'L-os-;in GELES, cALito 'iNi i. l

through switch 32 to shoe 27 and contact block 30', then'ce by wire 36 to solenoid 6 and track onto the branch track, and after it'has by wire 37 .to ground. The. solenoid 6 thus energized, operates through the connections 8, 9 and 10 as shown in Flg. '1, (or through the connections 18, 19, and '21 as shown in Fig. 3), to move the sw tch-tongue over to position for turning the car onto] the" branch line; As" the car passes ofi' the main fully left the main track, the contact shoe 27 will pass onto the contact block 30 in the track bed establishing connection from operating lever 24 to disengage it froin'lever trolley 33 through circuit 31, shoe '27, contact block 30, wire 38 to releasing solenoid 7, thus operating lever 12 to disengageit from lever 9 ,or, in the torn shown in Fig. 3,

- T 'e invention is app icable in connection withrailway semaphore signals as shown in 'Fig. 4, wl1ere 40 designates the semaphore mounted on a column or pole 41,-the lever 9 of solenoid 6 beingconnected to operate '40 a. car or train passes onto a sect on, it estabthe operating rod 43 for the seina hore, and lever 12 being adapted to lock tie lever 9 in operated position and to be released, by

solenoid 7, as above described.v In this case the solenoids 6 and}? are connected in two circuits 45, 46 res ectively connected to two insulated contact locks 47, 48 at the ends of a block of the track, these two circuits 45, 46, respectively, including batteries 49, 50. As

. lishes circuit by grounding the insulated contact block 47, current passing from bat-,- tery 49, throu h circuit to solenoid. 6 to ound "and through ground and contact lock 47 to the other side of the battery,

The solenoid 6 operates the semaphore and when the car reaches the end of the block it grounds the other contact block 48, operat-' ing the solenoidl7 in similar manner to release the semaphore which is returned automatically to safety,v
