UNITED STATES PATENT OFFICE.
JOHN MARTIN TREBER, OF LOUISVILLE, KENTUCKY.
TELEG RAPHIC RELAY.
SPECIFICATION forming part of Letters Patent No. 432,098, dated July 15, 1890.
' Serial No. 346,882. (No model.)
To all whom it may concern;
Be it known that I, JOHN MARTIN TREBER, a citizen of the United States,residin g in Louisville, in the county of J efierson and State of Kentucky, have invented certain new and useful Improvements in Telegraphic Relays, which the following is a specification.
My invention relates to improvements in telegraphic relays; and my object is to render the operation thereof extremely sensitive, While at the same time retaining a very simple construction.
I-Ieretofore a telegraphic relay has been constructed with a pair of fixed magnets and a pair of magnets over them carried by one arm of a weighted lever, said arm vibrating between a stop and a contact-piece; but in my invention I simplify this construction and avoid any unbalancing of the magnetic circuit.
My invention consists in the construction and combination of parts, as hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a side elevation of my complete relay, the c011- tact-post being in section. Fig. 2 is a plan of the same. Fig, 3 is an end elevation from the left of Fig. 1, and Fig. 4 is a diagrammatic view showing the circuits and the relay in outline.
A indicates the baseboard, having near one end two brackets b, which support the lower horizontal magnet B by means of its core, the brackets forming the poles of said magnet.
D indicates a T-shaped post carrying at its upper outer ends bearings (l for the fulcrumpins 6 of the armature-lever E. This lever has an adjustable weight 6 on its long arm and a yoke c at its outer end, carryingthe pole-pieces c, which are secured to the core of the upper magnet G. Near the end of the long arm of the lever a contact-post F is secured to the base-board, and has a horizontal block f, of insulating material, at its upper end. This block is recessed to form a seat f for the end of lever E and carries the contactspring G. At the upper end of post F is a contact-pin 11, said pin and post being insulated from an inclosing-tube.
Four bindin -screws for the circuit-terminals are shown at 1, 2, 3, and 4, and near the bracket 1) areshown two more binding-screws 5 and 6. Connections are made as follows:
From screw 1 to lower magnet B, from B to screw 6, from'screw 6 to upper magnet C, from Gto screw 5, (the two latter connections .being coiled around the pivot-pins e of the lever, as shown in Fig. 2, to avoid interference with the free movements of said lever,) and I from screw 5 to screw 2, the terminals of the main or operating circuit being attached at l and 2. From screw 3 connection is led to the T-post D, which supports the lever, and from the contact-spring G to screw 3 through a local battery I and through a sounder or other local translatingdevice :r. The current in this circuit may pass from post D to lever E spring G. Additional circuits might be con-' trolled by placing springs or contact-points on both sides of the armature-leverat proper points to engage circuit-terminals.
The upper magnet O, besides being in itself an electro-magnet excited by the same main current which excites magnet 13, is also the armature, the north pole of magnet C being opposite the south pole of magnet B and the south pole of the former being opposite the north pole of the latter. The two magnets, which are substantially equal in power, have an equal attractionfor each other, and the device is therefore extremely sensitive.
The weight c serves to adjust the tension of the armature by being set at different positions of the longer arm of the lever.
The vibrations of the lever by the main current exciting the two single magnets causes an alternate make and break of the two local circuits, one circuit being made through the armature-lever and contact-spring G and the other through spring G and contact-pin H, the two circuits including, respectively, the
sece
of the first-mentioned magnet, a main circuitincluding the said magnets, and a plurality of local circuits operated by the contact end of the lever, substantially as described.
2. In a relay, the COllllJlllFtiilOll, with a staiionary magnet, of an armature-magnet car-- ried at one end of a lever, a contact-spring above the other end of the lever, a contactpin beyond the end of the lever and under the spring, amain circuit including the said magnets, a connection from a battery to the spring, and branch connections from the battery to the lever and to the contact-pin, said branchesincludingtranslating (leyicesavhereby the Vibrations of the armature-lever will alternately operate two local circuits, substantially as described.
3. In a relay, a single n'nignet having its pole-pieces in the form of two brackets, the feet of the brackets being secured to the base out of the Vertical plane of the magnet, whereby the magnet may be located close to the base, and the said pole-pieces serve the double function of influencing the armature and securing the same in position.
In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
JOHN MARTIN TREBER.
