CONTROL DEVICE.

Specification of Letters Patent.

Application filed May 20, 1915. Serial No. 29,399.

To all whom it may concern:

lie it known that I, HARRY R. FOWLER, of Toledo, Lin-as county, Ohio, a citizen of the United States of America, have invented new and useful. Control Devices, of which the following is a specification.

This invention relates to inter-connected elements of indication and operation.

This invention has utility when incorporated in connection with determining the position of a main driven member, say in railways or highways, as switches, crossings and movable bridges, and simultaneously cmitrolling other operations, as lighting lamps for signaling or indication, and operating devices, as semaphores.

rheferring to the drawings:

Figure 1 is a view, with parts broken away, showing an embodiment of the invention in connect-ionwith a movable bridge;

Fig. 2 is a side elevation, on an enlarged scale of features of the devices disclosed in Fig. 1, I

Fig. 3 is a detail view of a group of terminals operable in conncctionwith a group of the devices;

Fig. 4 is a side elevation of one of the compound lever devices;

Fig. 5 is a section on the line V-V, Fig. 2, looking in the direction of the arrow;

Fig. 6 is a section on the line VI-VI, Fig. 4; and

Fig. 7 is a wiring diagram of the control device connections.

The way 1 may have therein the movable member or bridge 2 driven by the motor 3 as determined by the controller 4.

For actuation in synchronism with the travel of the driven member 2, the sprocket chain 5 may extend to the sprocket wheel 6 on the shaft '7 in the housing 8.

Adjustably mounted on the shaft 7 by set screws 9 are the arms 10, 11, 12, 13, 14, which may be set for any desired or successive timing for actuation of control devices.

Connection carrying bars 15, 16, 17, 18 (Fig. 5), are mounted in the housing 8.

These bars may be of slate or an insulating material when the connections controlled are electric circuits.

The bars 15, 16, have mounted therebetween by the screws 19, the fulcrum blocks 20. Each block 20 carries centrally the fulcrum pin 21 serving as a common fulcrum hearing or axis for the pair of upwardly into seat 26 by the work or loading springs 28 engaging the lever 22 beyond the power receiving rollers 25.

These springs 28 through the pin 29 apply power to the lever 23 between its fulcrum pm Working member. The free end of the lever 23 has the pin 30 mounting thereon the fiber or insulation H-lolock 31 rockably as to the lever 23. This block 31 may have conducting faces or contact plates 32 on opposite sides thereof with the conductor jumper 33 therebetween. Terminals or contacts 32 may be connected by the line 34 to terminals 35 on the bar 17. The opposite bar 18 is provided with terminals 36 opposing terminals 35, and also for being contacted by the movable terminals 32.

WVith the way clear and the bridge 2 down indication thereof may be had by light 37 through which electric current may be supplied by the line terminals 32, bar terminals 35, lines 34, 39, completed by the return line 40. Upon the bridge starting to move, the arm 10 may be adjusted to at once shift its control device, breaking the circuit in the line 39 as well as through the line 41, coil 42, and line 43, thus deenergizing the coil 42 and opening the switch 44. The circuit 45 is accordingly broken, solenoid 46 deenergized and the semaphore arm 47 is raised by its counterweight 48 to danger or horizontal position, from the dropped orclear position.

The throwing of the control device which breaks the circuit through the light 37 at Once connects through the terminal 36 to light the lamp 49 indicating to the bridge operator the position of the bridge, even though the operator is not in a posltion to see the bridge. As the travel of the driven member 2 continues, the second arm 11 is effective to break the circuit through the lamp .9 by Shifting another control device,

21 and the relatively rockable 38, through the device and simultaneously light the indicating lamp50. i Thissuccessive operation may occur with the remaining indicators 51,52, 53, of such number as desired and disclosing stages required. In the return of the driven member or lowering of the bridge, the opposite actionoccurs, for the arm 14- in its backward swing first causes a control device to darken the lamp 53 and turn on the lamp 52, and these steps recur in the reverse order of the bridge opening till with the 1. A movable switch actuating driven member, quick throw switch means brought to actuation by said member, said switch means embodying a yieldably connected trip pable pair of circuit closing levers, a relatively rockable contact face carried by one of thelevers and an opposing member having a contact face with which the switch means may directly make and break con tact, said contact faces each being independent of the driven member.

2. A switch comprising first and second members, a common pivot bearing for the said members, an'operating member movable in one direction to engage the first member remote from the bearing, a spring connectingthe first and second members and coacting to throw the first and second members away from actuation by the operating member after'actuation by the-operating member is initiated, and stop means for the first member inclearance position as to the operating member in continuation of travel of the operating member in the direction efl'e'cting the throw actuation by the spring.

3."A'switch comprising first and second members, a common pivot bearing'for said members", an operating member movable in one direction to engage the first member at a first point remote from the bearing-and movable in*anotherdirection to engage the first member at' a second pomt remote from the bear1ng,--a sprlng-connectlng. the first and sec-ond m'embers remote'from the bearingffor throwing the first member away from the operating member, and stop means for the-first member in clearanceposition at its first point for continuation of operating member travel initiated by the operating member and thrown by the spring in one direction and as to the first member second point for travel initiation and throwing in another direction.

efAswit'ch comprising first and second levers, a common fulcrum bearing therefor providing a pair of'spaced stops, a pair of pins carried by the first lever remote from the bearing, one pin at one limit of travel ofth'e first lever engaging with one stop and at the other limit of travel of the first lever the other pin engaging the other stop, a spring connecting the levers remote from the bearing, and a rotatable operating arm in its travel clear of stop engaged pin but movable to initiate travel of the first lever by engaging the other pin to bring the spring into action to throwthe engaged pin clear of the arm into its stop.

A "switch comprising first and second levers, a supporting frame therefor providing a common fulcrum bearing for the levers and on each side of said bearing a stop, a'pair of laterally spaced rollers 'car ried by the first lever spaced from the bearing, one roller in the rocking or the first lever in one direction coming to rest in one stop'and the other roller in the rocking of the first lever in the other direction coming to rest in the "other stop, a spring extending to connect the first lever, more remote from the bearing than the rollers, with the second lever spaced from the bearing, contact means carried by the second lever more remote from the bearingthan the spring connection to the-second lever, a cont-act'member opposing the contact means to beengaged thereby upon a throwing of the switch, and an operatingarm' rotatable in one direction to engage a roller and initiate its travel for bringing the spring into action to throw said roller clear of the arm and against its stop while simultaneously shifting. the pair of levers.
