RELAY non wmnness smnanme sysrnars.
Original application filed January 22, 1917, sci-1&1 No. 143,560. Divided and all; application an fle itember 11, 1919.eria1-'N o. 323,065.
To all whom it may concern: 1 Be it known that I, FREDERICK S. McCall LoUcH, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and
' State of Ohio, have invented new and useful-Improvements in Relays for Wireless Signaling Systems, of. which the following is a specification, the principle of the in-j vention being herein explained and the bestmode in which I have contemplated ap plying that. principle, .so as to distinguish it from other inventions.
This invention relates to relays for-Wireless signaling systems, and is herein shown and described as embodied in'a'system for signaling elevators and embodies subject'- matter divided'out of original application Serial No. 143,560, filed January'22, 1917..- An essential object is toprovide a simple, efficient means for actuating signals in elfevator cars and on the-various floors of the building, and which shall be comparati'vely cheap to manufacture and not liable to get out of order. s
In the system use a high frequency generator preferably connected by a single wire with capacity members arranged at the several floors for one elevator car or a plurality of elevators in a bank. I arrange capacity members on' the car adapted to be brought into proximity with the successivecapacitymembers for the floors so that when a signal switch is actuated on any floor it may connect the corresponding capacity member with the. generating means and cause energy to be transmitted across the air dielectric from one capacity to the other while they are adjacent, and I arrange on the elevator car a relay adapted to be actuated by the electric impulse passing from one capacity to-th'e other,
This relay may control a visual or audible signal on the elevator car.
To make the system more complete 1 may arrange an additional capacity plate on each car at each floor and a relay on each-floor to actuate a signal indicating that a car is about to respond to the signal of the waiting passenger.
,My invention is hereinafter more fully described in connection with the drawings,
1 'which illustrate a convenient arrangement thereof, and the essential characteristics of the invention are set forth in the claims.
disclosed'in said patent I;
. Figurel is a side elevation of the'relay;
Figure 2 is an axial section thereof; Figure 3 is a transverse horizontal section' taken substantially'on the line- 3-3 of Figure'el is a similar section taken substantially on the line 4--4 of Figure 2.
' I Figure 5 is a section onthe line'55 of Figure 2.
For, actuation of the signals on the car and on' the variousfloors I provi e relays such as disclosed herein-which .a-re'sovcon structed as to be aetuatedby that form of energy which surrounds a. wire connected with one terminal of a high potential transformer connected with 'a high -fr'equenc y generator and which energy does not de lpendyfor. its existence upon any: return or ground wires. I have found in actual practies. that such -a relay can be actuated through a single wire so connected. even when the wire is divided'by' capacit'y'plates separated by an air gap of" several inches.
Thus bya'bringing such capacitiestogether- I accomplish the selective signaling .de-I scribed, One form of such a relay is illustrated in Figures 1 to'5-inclusiveandmay be constructed as follows i At 7 0 is indicated a suitable support on which is mounted a block or casing -7lpr eerably of insulating material. Two lateral.
Specification of Letters Patent ,Patentd an 17," 1922: l
The spindle 8O is provided with a down ward extension 86 insulated therefrom and adapted to contact with a plate 87 connecte'd with a battery (SS-which is included in one-of the signal light circuits, the connection being-made through a wire 89 which is'so coiled about the eXtension'SG as not to interfere with its rotation or vertical movement. A'suitable cap 90 supports the plate 87 and protects the contact 86.
This relay depends for its operation upon the} attraction of one a'ir electrode to another when charged With the energy which -follows-a wire connected with a source of high frequency current of a high. potential W hen the field of energy surrounds the Wire leading to therelay, the wings 7 8 are caused to move downwardly and turn slightly with-,
inv the cage 76 by their attraction to the leaves 77; This action occurs when the capacity plates are 1n proximity and after the.
energizing of one of the push button signal circuitswhich causes the relay to make a contact at 86- and 87, whereu on the light .10 becomes incandescent.
I found by experiment that thisrelay may be constructediin many diil'erent ways, the
essential features being an electrode attracted to some other object, and I have also found thatthe action may be augmented by the use of a small resistance wire. which heats when, the energy passes; along-the same. Accordingly I may make the coil spring 81 of such wire so that its expansion,
due to the heating, mayincrease and make morepositive contact.
the movement of the relay a wire supporting said spindle, said wire wire spring supporting said spindle andadapted to be heated by the electric energy I conveyed to the relay.
4:. In a signaling system, a static relay having. in combination, fixed plates, a movable spindle, vanes attached to said spindle, said p ates and vanes being set so as to make an an le less than ninety degrees with said spindle, and a Wire supporting said spindle and adapted to expand when electric energy is conveyed by it:
- 5. In a signaling system, a static relay having, in combination, fixed plates, a movable spindle, vanes attached to said spindle, saidplates and said vanes being set at angles less than ninety degrees with said spindle, a spring supporting said spindle, and a contact member attached to said spindle.
,6. In a signaling system, a relay having, incombination, stationary plates, a movable spindle, vanes attached to said spindle. said plates and said vanes being set at an angle with said spindle, so that when they are attracted by each other, said spindle. will be caused to rotate and to move longitudinally.
7. In a signaling system, a relay having, in combination, stationary plates, a movable spindle, vanes attached to said spindle. said plates and said vanes being set at an angle other than ninety degrees with said spindle, aconducting support for said spindle adapted to expand when conveying electric energy. said plates and vanes and said conducting support coacting to move said spindle longitudinally.
Signed by me, this 8th day of September, 1919.
