SIGNALING SYSTEM.

Specification of Letters Patent. Patented line 4, 1912.

Original application filed September 1, 1810, Serial No. 580,068. Divided and this application tiled tremity a toothed elemc t 8 secured thereto by means of a. set screw 9. A clockwork. mechanism carried by the framework 10 and of ordinary construction, drives the shaft 3 after the shaft has been moved in a direction against said clockwork and a governor 12 controls the speed of rotation. A spring 13 is adapted for engagement with the teeth 14 of the element 8 and is suitably mounted upon ,an insulating bracket 15. The spring 13 in association with the movable element 8 controls the circuit through a relay 16, which circuit also includes a battery 17. The relay in response Be it known that I, HARRY O. RUGH, a citizen'of the United- States, residing at Sandwich, in the county of, :Gook and State of Illinois, have invented a certain new and I useful Improvement in Signaling Systems, of Which'the following. is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to circuit controlling a: aratus and is of more particular service in connection, forinstance, with call boxes for selective signaling systems, although of course notrso limite My invention herein isa divisional application of a co-pending application of mine, Serial No. 580,068, filed Sept. 1, 1910 in which a complete call box is set forth and in which my. present invention was originally disclosed.

My invention herein concerns itself with a movable member-of a call box in association with which switching elements are provided of a certain character which control certain circuit changes. The switch eleassociated with the movable element and this frictional engagement permits a very simplified structure of devices of this character.

I will explain my invention more in detail by referring to the accompanying drawing setting forth one embodiment thereof in which:

Figure 1 is a front view of a call box constructed in accordance with my invention; Fig. 2 is an interior View of the call box setting forth the structural arrangement of my invention, and: Fig. 3 is a diagrammatic view setting forth the circuitarrangements.

The call box of my invention has a cover plate 1 associated with 'a box 2, which cover plate carries a shaft 3 mounted therein. On the front face of the cover plate is 1'0- tatably mounted a disk 4 which is secured to the shaft 3. A handlc-5 loosely mountprovidcd with a knob 6 any angular position 4 and is adapted to mit the "battery impulses from a battery 19 tors 20 and 21. ing the plate 4 rotates the movable element 8 into a position from which the clockwork rotates it, and during this restoring notation of the element 8 the substation selecting impulses are transmitted.

, During the time that the element 8 is being set to its initial call sending position, it is of advantage that a long impulse be transmitted in order to place the substation signal receiving devices in condition to recelve the impulses which are later transmitted upon the reverse movement of the element 8, and to accomplish the sending of this long impulse I provide two springs 22 and 23' which are independently mounted on an arm 24 and which when in a closed position close circuit through the relay 10 so that an impulse is transmitted. The novel structural features of these circuit elements are the subject matter of my present invention. The spring 23 carries a frictional element 25, which frictional element engages the movable element ,8. Now when the element 8 is rotated referring to Fig. 3 in a contra clockwise direction, which is the setting operation, then the friction between the elements 8 and 25 causes a fiexure of the spring 23 so that it engages spring 22 is adapted to be set at with relation to the disk Fig. 3, then the friction between the elements 8 and. 25-moves the spring 23 away from thespring 22 and circuit through the relay 16 is broken except as it is made when teeth 14: engage the spring 13.

depending upon where the button 6 is placed with relation to the openings 7 in the said 4 more par ticularly to 2, carries at its opposite experiodically to impulses actuates an armature l8 totrans over aline circuit comprising the conduc- The handle 5- when rotatand closes circuit through the relay 16. I Now 'when the clockwork rotates the ele ment in a. clockwise direction, referring to v This frictional control of the circuit changing springs 22 and 23 serves'to provide a "cry simple and efficient controlling device which is of service in this and of course other connections.

Having thus described one form which my invention may take, what I claim as new and desire to secure by Letters Patent .is:

1. A call box havinga circuit controlling clement, contact making devices mounted 'independently of said element, controlling means for said contact making devices also mounted independently of said element and having-frictional engagement with said-element. whereby movement of said element in one direction willestablish certain circuit conditions, and a movement in the opposite direction of the element will establish different circuit conditions. i

2. A call box having a movable circuit controlling element, contact making devices mounted independently of said element, controlling means for said contact making decontrolling element, contact making springs vices mounted on one of said devices and having frictional engagement with said element, whereby movement of said element in one direction will establish certain circuit conditions, and a 'movement of the element in the opposite direction will establish different circuit conditions.

3. A call box havinga-movable circuit mounted independently of said element, controlling means for said contact making springs mounted on one of said springs and having frictional engagement with S31d 8l8 ment, whereby movement of said element in one directionwill establish certain circuit conditions, and a movementof the element in the opposite direction will establish difierent circuit conditions.

5. A call box having a rotatable circuit controlling element, contact making devices mounted independently of said element, controlling means for said contact making devices also mounted independently of said. element and having frictional engagement with said element, whereby movement of said element in one direction will establish certain circuit conditions, and a movement in the opposite direction of the element will establish different circuit conditions.

6. A call box having a rotatable circuit controlling element, contact making devices mounted independently of said element, controlling means for said contact making devices mounted on one of said devices and having frictional engagement with said ele ment, whereby movement of said element in one direction will establish certain circuit conditions, and a movement of the element in the opposite direction will establish different circuit conditions.

7. A call box having a rotatable circuit controlling element, contact making springs mounted independently of said element, controlling means for said contact making springs also mounted independently of said element and having frictional engagement 0 ;with said element,'Whereby movement of said element in one direction will establish certain circuit conditions, and a movement of the element in the opposite direction will establish different circuit conditions.

8. A call box having a rotatable circuitcontrolling element, contact making springs mounted independently of said element, controlling means for said contact making springs mounted on one of said springs and having frictional engagement with said element, whereby movement of said element in one direction, will establish certain circuit. conditions, and a movementof the element in the opposite direction will establish diiferout circuit conditions.

In witness whereof, I hereunto subscribe my name this 31st day of August, A. D., 1911.
