SUPERVISORY RELAY.

SPECIFICATION forming part of Letters Patent No. 705,092, dated July 22, 1902. Application filed February 4, 1901. Serial No. 45,964. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM KAISLING, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Supervisory Relays, (Case No. 16,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, form- IO ing a part of this specification.

My invention relates to a supervisory relay more particularly designed for telephone purposes, although equally applicable to other uses.

The object of my invention is to provide a compact and efficient relay, and more particularly to provide means for mounting the armature of the relay.

I have illustrated my invention in the accompanying drawings, in which Figure 1 isa longitudinal sectional view of the relay of my invention. Fig. 2 is a view thereof, partially in section. Fig. 3 is an end view of the relay. Fig. 4 is an end view of the relay, the capf being in section and the armature 0, together with the greater portion ofitssupporting-strip c ,beingremoved. Fig. 5 is a detail View of one of the relay-contacts and the mounting therefor. Fig. 6is adetail view showing the armature and the mounting therefor. Fig. 7 is a detail view showing the manner of securing the armature to the suspending-spring. I

Like letters refer to like partsin the several figures.

The relay is surrounded by a shell or of magnetic material, and within this shell the core a is mounted, the core having a threaded shank a adapted to pass through an open- 4 ing in the rear of the shell a and adapted to be secured in position by means of a jam-nut a Upon the core a the winding Z) of the relay is mounted, the winding being held between insulating end pieces b The ends of the winding h are connected, respectively, with the leading-in conductors or rods 12 l)", which pass freely through holes Zr I) in the end of the shell Ct.

The armature c is preferably made circu- 5 lar in form and carries at the center a tapped hole adapted to receive a screw 0, secured in position by a jam-nut 0 The end of the screw carries a contact-point 0 preferably of platinum, which is adapted to serve as one of the contacts of the relay. The armature c is suspended opposite the end of the core a by means of a strip 0 preferably of copper, and adapted to serve as a spring. One end of the strip 0 is secured to the end of the shell a by means of the screw 0, and the opposite end of said strip 0 is adapted to rest in a saw cut or slot provided in the face of the ar mature 0 near the periphery thereof. The end of the strip 0 is bent substantially at right angles for insertion in said saw cut or slot,and after the said end has been inserted in the saw-cut the circumference of the armature directly over the slot is prick-punched to secure the armature to the strip. The strip 0 serves to normally maintain the armature a short distance from the end of the core, and when the armature is attracted the same is drawn toward the core to close together the relay-contacts. WVhen the armature is attracted, the metallic circuit is completed from the shell-terminal e through the shell and suspension-spring a to the armature-contact c thence to the back contact (1 and by wire 6 to terminal 0. By this means of suspension the weight of the armature is balanced, and therefore the only strain to'be exerted by the magnet is against the spring copper strip 0 Moreover, this strip serves to make a good electrical contact between the armature and the shell of the relay.

Upon the front insulating-plate b a spring or strip d is secured by means of a screw d. The lower end of said strip (Z carries a platinum contact (Z adapted to be engaged by the relay-contact carried upon the armature c. The platinum contact (1 carries a shank (Z extending to the rear of the strip (Z, said shank being guided in an opening provided in an insulating-block d, inserted in a bore in the end of the core a. The face of the insulatlug-block (Z rests at a distance from the end of the core, so that the contact d rests wholly within the end of the core. A slot (1 is provided at one side of the core to accommodate the passage of the strip (1. An opening is pro- I00 vided through the strip 0 supporting the armature, to thereby permit the contact 0 to engage the contact (1 A leading-in wire or rod 6 is secured to the head Z) and passes through the end of the shell a, being insulated therefrom by means of a bushing c. Said rod 6 is electrically connected with the strip (.1 by means of a conductor 6 the end of the shell (7., being in electrical contact therewith. The wires 6 and 0 form the terminals of the circuit adapted to be controlled by the relay'cont-acts. For the purpose of illustration I have shown a battery 0' and a lamp 0" in circuit with the wires c and 0 The circuit may be traced from the battery through the lamp 9", wire 6, conductor e strip (Z, relay-contact (Z thence, when the armature is attracted, to contact a, armature c, strip 0 to shell a, thence through wire (2 to the opposite pole of the battery.

Upon the end of the shell Ct is mounted a cover or capf, said cover having upon opposite sides the bayonet-channels ff, adapted to engage, respectively, the pins f f carried upon the shell a. The cap f carries a screw f By turning this screw the same may be caused to engage the head of screw 0 to limit the distance to which the spring may retract the armature.
