VERNON CANO, ARTHUR A. CANO, AND LEWIS CANO, OF NEW YORK, N. Y.

ELECTRICAL-CIRCUIT CONTROLLER.

To all whom it may concern Be it known that we, VERNON CANo, AR- THUR A. CANo, and Lnwrs CANO, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Electrical-Circuit Controllers, of which the following is a specification.

This invention relates to electrical circuit-contr0llers and especially to a multiple circuit-controller by means of which two normally separated electrical conductors may be brought into contact at any one of a plurality of points.

A special object is to furnish a multiple circuit-controller of the simplest and cheapest construction for closing contact between two adjacent conductors at any one or more of a large number of points, the preferred construction employed being one in which substantially nothing more is involved than the two conductors themselves and a supporting strip for carrying them.

The invention is adapted for use in connection with any ordinary electrical controlling or other circuit in which it is desired to make contact at will between two main conductors at any one or more of a large number of points in the length of said conductors, the invention being especially applicable to the giving of a visual or audible signal from various points in a building or room and to the protection of walls, etc, against burglarious entry.

Other features of the invention not hereinbefore referred to will be hereinafter clescribed and claimed and are illustrated in the accompanying drawings, in which Figure 1 is a face View of an electrical circuit-controller embodying our invention and comprising two electrical conductors carried and normally separated by a strip of insulating material; Fig. 2 is a similar view showing a modification of the construction; Fig. 8 is a view similar to Fig. 1 showing the application of'the invention in a circuitcontroller of large area having several rows of points of contact of conductors instead of Specification of Letters Patent.

Serial No. 803,578.

the single row shown in the other views, and Fig. 4: is an enlarged transverse section of Fig. l, the section being taken in line 4l,

Fig. 1.

Similar characters designate like parts in all the figures of the drawings.

Referring first to Fig. 1, we have illustrated in this view a pair of electrical conductors carried by an insulating support or strip in such a manner that said conductors are normally separated from each other at one or more points. Said insulating support also embodies in this case means for bringing said conductors into contact with each other at any one of said points. lVhile this view illustrates a circuit-controller with conductors having a plurality of points of separation and a plurality of devices for efiecting contact of the conductors at such points, the invention is embodied in a single unit of the controller shown in said view and such a unit would comprise two conductors such as are illustrated at 2 and 3, normally separated at a single point, as indicated clearly in Fig. 4:, and a device, such as the tongue 4, integral with the main body or strip of insulating material, 5, for pressing said conductors into electrical contact. The strip 5shown is in the preferred construction a flexible stri 3 of insulating fiber relatively thin but of su cient thickness to have a fair amount of stiffness, and this strip has a large opening or openings, such as 6, therein at opposite sides of which the conductors 2 and 3 cross each other but are out of contact normally. This contact may be made in any suitable manner, but we prefer, as just stated, to cmploy tongues, such as 1, which are disposed in the openings 6 but are of smaller area, so as to leave a clear space around them except at the point of connection of each tongue with the strip 5, the object of this being to facilitate the insertion of the conductor 3 in place under each tongue and between it and the body of the strip.

Each conductor may be secured to the strip in any desired manner, but preferably by threading it through openings properly located in the strip. The conductor 3 is here shown as a fiat strip of sheet metal and the conductor 2 as an ordinary round wire. For the round wire conductor small circular holes, such as 7, are preferably provided; while for the flat strip, long slots, such as S, are preferable, these being disposed in pairs close together as shown in Fig. 1. The flat strip is threaded through these slots and under the tongues 4 and always passes the openings 6 on one side thereof, that is, at the front, as seen in Fig. 1; while the conductor or wire 2 is threaded through the small roundholes 7 in such a manner that it always crosses an opening (5 and the conductor 3 at the opposite side of the strip 5, that is, at the back thereof. Thus at the points of crossing-the conductors are always normally separatedso thatthe circuit remains open and no current can pass. The tongue t-is located at one side,-here the front, of both of the conductors and of the device as a whole and is intended to close contact between -the conductors by pressing them together. To accomplish this each tongue of course has suflicientmovement to assure the bringing of the conductors into engagement,qand the conductors themselves have sufiicient play in the openings 7 and 8 and are sufliciently' loose to permit them, though normally separated, to be brought together readily.- I

It will be noticed that the conductor 3 extends substantiallyin a straight line from end to end of the circuit-controlling strip, whereas the conductor 2 is passed back and forth. transversely of the conductor 3 for a considerable portion of its length, in order that points of crossing may be established at each opening by each conductor at which electrical contact may be made. The conductors 2 and 3 at their ends may be suitably secured to terminals, such as the metallic eyelets 9 and 10, which complete the circuit-controllingstrip. This strip as a whole may then be secured in place along any wall or other surface to which it is desired to apply it and may be connected in anyproper electrical circuit to be controlled by merely connecting the terminals of said circuit to one pair of terminals 9 and 10 on r the strip.

nary round wire, 3, is threaded under said tongues and through small round openings, 8", similar to those shown at 7 Otherwise the construction is substantially identical with that of Fig. 1 and the operation the same.

In Fig. 3 we have illustrated a modification of the invention showing its application to the protection of a surface of large area. Here a conductor 2 is threaded back and forth across and lengthwise of a relatively wide sheet, 5, of insulating material and passes through numerous small openings 7 disposed in a plurality of rows both lengthwise and crosswise of said sheet. We have also shown three flat strip conductors, 3, like those of Fig. 1, these three conductors being illustratedv as parallel with one another and as connected at their opposite ends by conducting wires, 11, by which they are joined in multiple to the terminals 10 as before; the conductor 2 being connected substantially as before described to the cont-actterminals 9. The contact strips 3 are threaded, as in Fig. 1, through pairs of parallel slots 8. The construction is such that there are'three rows of breaks at the openings 6 and the tongues at any one of which points the circuit may be closed by pressing on the proper tongue. For convenience the large openings 6 and the tongues in. alternating rows in this view are staggered, as are the pairs of slots The positions of some of the small openings 7 forithe round wire 2 are also varied because of the staggering of the'tongues of different rows. In other respects, however, the construction is substantially identical. with that of Fig.1 and themode of operation is the same, there being, however, instead of a single series of breaks in multiple three series of breaks in multiple. i

It will be obvious from the foregoing that our improved electrical circuit-controller may be employed either as a single unit or as a. strip consisting of a single row of units. or that it may embody a large numberof elements in each of a. large number of rows for protecting a surface of great area over which contact may be established when any one of a large number of tongues, such as at, is pressed either accidentally or intentionally.
