i I will describe one form of. apparatus embodying my invention, and will then point out the novel features thereof in claims.

The accompanying drawing is a diagrammatic' view illustrating one form of apparatus embodying my invention. Referring to the drawingg my invention is shown as comprising railway traflic controlling devices, here shown as two switches of a crossover designated respectively operating motor designated by the reference switch 'A actuates a circuit-controller P comprising a contact 38 39 which is closed its full reverse position. The circuit controller P also comprises a contact 4Q-f41' which" is closed when the switch occupies its f is closed at all other times. In similar manner a circuit controller Pl controlled 1 bynormal position and a contact 4042 which switch A 'comprises a contact 46 47 closed at alltimes except when the switch'A 'occupies its full normal position. Thecircuit controller P also comprises a contact 43. 44 j which is closed when the switch A occupies its reverse position and a contact 43 which is closed at all other times I The motor M is controlled by a. manually operable lever L which maybe one of a mum ber of such levers located at a point remote from the switch, such, for example, as in'an v A 1: interlocking cabin. As here shown, the lever 45 L is capable of assuming four positions indi- 'cated by dotted linesfon the drawing, and

D and R. The lever L controls two NBcon which are each provided with an ton the lever L, to'terminal'Y. plied'to the motor "whichare closed for alllever positions between R and D. tus for controlling an electric motor such as a As shown in the drawing thelever L occupies its normal position N, and switches A.

and A are both normal. 1 If the operator wishes to reverse-the switches A and A he moves the lever L toward its reverse position, to close the RD contacts on the lever. v

Current then flows/from terminal X of a source of energy not shown in the drawing, throughan RD contact on leverL, conductor- 11,- contact 43;4.5 of circuit contrOllerPF,

rent is supplied to motor M, from terminal X, through an RD contact on the lever L, conductor 11, contact 43 44 of circuit controller P wire 53, contactY38- -3 9' of circuit concontact on lever L and back to terminal Y 7 of troller asy nmetric'unit 6,'field 2 off'motor M,asymmet ric unit8, wire 14,],armature' l of motor M, conductor 10,1and anRD contact "Current sup- Mover the circuit just traced causes the motor to move switch Afto.

,In order to restore the switches A ,an'djA v to their normalpositions, lever Lis returned toward'its N position.

asymmetric unit 49, field 2 ofmotor M asymmetric unit51, contact et6i7 of-circuit controller P wire 55, contact %1 of circuit controller P, wire 54, conductor 11, and an NB contact on lever L to terminal Y. It

will therefore, be observed thatwhen'the lever L is moved from one extreme position to the other, the motors M and M are successively operated to reverse the corresponding switches. That is to say, in moving from normal to reverse, the motor Ml is first con- 1 nected with the source and when this motor has moved its switch tothe full reverse position, the motor M is connected with the source. ,Similarly, in switch movements from reverse to normal, the motor M is first (connected with the source, and'motor M v is not supplied withenergy until switch A has been restored to its full normal position.

It should be understood, of course, that the lever L may be provided with-locking apparatus similar to that shown in my copending application hereinbefore referred to, and that an'indication relaymay beacontrolled by pole-changers,associated with the is understood that 'VEIIIOLIS' changes and Iicla m i switches A and A in accordance with the usual and standard practice. These parts have been omitted from the present drawin in order to simplify the disclosure.

modifications may be made therein within the scope of the appended claims without de- Per mgfrom the sp it a d cope o y in- 1 vention. 7 V VHavingthus described my invention, what '1. In combination, a railway switch,
