IMPROVEMENT IN TELEGRAPHS.

Specification forming part of Letters Patent No. 13,655, dated October 9, 1855.

To all whom it may concern:

Be it known that I, WASHINGTON ABRAM PEASLEE, of Indianapolis, in the county of Marion and State of Indiana, have invented an Improvement in Instruments for Telegraphic Purposes; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes it from all the other things beforeknown, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 is a side elevation. Fig. 2 is a ground plan; Figs. 3 and 4, end views; Fig. 5, detached view of the armature-lever Fig. 6, diagram of circuits, &c. 1

My invention consists in placing two receiving electro-magnets, in combination with an armature-lever having ground-connections, in a main telegraph-circuit, so as to form two separate circuits, and the transmission of signals from either one of the circuits so formed to the other without the use of other agency than the power of the batteries in the main circuit.

Fig. 5 is an armature-lever, made of ivory or other non-conducting material balanced upon axles t t". Upon one side of the armaturelever is a metal lining, f, touching one of the axles, 'i, and extending from the axle i to the 1) top of the armature-lever, m, and upon the 0pposite side of the armature-lever is a similar metal lining, f, touching the other axle, t", and extending from the axle t to the bottom of the armature-lever a.

Upon the armature-lever are metal arms 13 13 ,13? being slightly the heaviest, which, with respectto each other, are upon opposite sides of the armature-lever and at equal distances from the axles t 'i. The pivots of the axles i t" of the armature-lever rest in standards K K. The upper and lower ends, on and n, of the armature-lever vibrate between the points 0 0 and 0 0 The points 0 o are of non-conducting material. The points 0 0 are of metal. The points 0 0 are supported on the frame A A, independent of the standards K K, and the points 0 0 are in separate standards fastened to the platform of non-conductin g material 7.

B is apair of helices supported by the standard D, and is above the axles of the armaturelever and opposite the metal arm B 0 is a pair of helices supported by the slide S and is below the axles of the armaturelever and opposite the lower metal arm, B The helices G, in relation to the helices B, being on the opposite side of the armature.- lever, the helices B and G are placed near enough the arms B and B to attract them when the helices B and O are magnetized.

7 is aplatform of non-conducting material. S S are metal plates made fast to the platform 7. S S are movable slides, which rest in dovetailed grooves in the metal plates S S and support the standard D and the helices G. S S are set-screws, and take hold of the slides S S By the use of these screws S S the helices B and C may be advanced toward or removed from the metal arms B B of the armature-lever, as may be necessary.

at d are the main wires leading from the batteries into the metal standards 19 q. d d are small wires leading from thestandardsp q to the helices B O. b b are small wires leading from the helices B O to the metal standards 19 q. 0 O are wires leading fromthe standards 19 q to the metal points 0 0 Z l are wires leading from the ground to the metal standards K K. a a. is a wire connecting the standards 1n diagram, Fig. 6, at w are ground-plates. Z Z are batteries. 8 8 are break-circuit keys. (I d are the main wires leading from the breakcircuit keys to the standards 12 q. 61 61 are wires leading from the standards 1) q to the helices B O. b b are wires leading from the helices B" G to the standards 19 q. a a is a wire connecting the standards 12' and g. c c are wires leading from the standards 1) q to the metal. points 0 0 g g, the armature-lever; B B the metal arms attached to the armature-lever; o 0, the non-conductin g points, representing the armature-lever resting against them when balanced in its perpendicular position. it represent the axles of the armature-lever. la la represent the metal standards; I 1, wires leading from the standards 7: k to the ground-plates w w. B 0 represent the helices. H represents a wire leading from the zinc pole of the battery Z. j represents a wire leading from the platina pole of the battery Z to the ground plate or. H represents a point of the breakcircuit key, which is connected with the main wire (1; j, a wire leading from the zinc pole of the battery Z to the ground-plate w; H a wire leading from the platina pole of the battery Z to the break-circuit key which is connected with the main wire d.

Operation: Diagram No. 6 represents the batteries, ground-connections, main wires, helices, vibrating armature-lever, 850., ready for operation, with the circuit broken at the point H of the break-circuit key 8. It being understood that the battery Z, having its platina pole connected with the ground by the wire 9" to the ground-plate 00, must have a groundconnection for its zinc pole also, to complete its circuit and bring it into action. But this is not the case, as is represented inthe diagram No. 6, the wire H, leading from the zinc pole of the battery Z, not being connected with the point H of the break-circuit key 8; cpnsequently the battery Z is inactive. The battery Z, being connected to the ground-plate 00 by the wire 3" leading from the ground-plate as to the zinc pole of the battery Z, which is connected with the reak-circuit key 8 by the wire H leading from the platina pole of the battery Z to the break-circuit key 8, the main wire d bein g in connection with the break-circuit key 8, and the metal standard q and standard q being connected with the helices G by the wire d,

and the helices 0 being connected to the metal standard q by the wire I), and the standard q being connected with the metal standard 1) by the wire a, a, and the standard 1) being connected with the helices B by the wire I), and the helices B beingconnected withthe metal standard 1) by the wire 6?, and the standard 19 being connected with the break-circuit key 8 by the main wire d, the point H of the break-circuit key 8 being the terminus of the unbroken connections leading from the platina pole of the battery Z and having no ground-connection at the .point H 5 consequently the battery Z is inactive also. The point H, being the representative of the platina pole of the battery Z, being brought in connection with the wire H leading to the zinc pole of the battery Z, the platina pole of the battery Z being connected with the ground-plate w by the wire j, the circuit is complete, having the zinc pole of the battery Z connected with the ground-plate ac, and the platina pole of the battery Z connected with the ground-plate w. The circuit now being complete the current passes from the zinc pole of the battery Z, which is connected with the ground-plate ac to the platina pole of the battery Z that is connected with the groundplate 00, charging and forming magnets at the same time of the helices B and O. The helices B and 0 being placed near enough to the metal arms B B of the vibrating armature- ]ever so as to attract the metal arms B B with equal force, the armature-lever is drawn from its perpendicular position (whereit rests, touching the non-conducting points 0 0 against the metal points 0 0 the metal points 0 0 be ing connected by the wires 0 c with the main circuit d d at the metal standards q.

Ground-connections are formed between the helices B 0 through the wires 0 and (Pleadin g from the metal standards 19 q to the metal points 0 0 the metal points 0 0 being in contact with the metal linings f f of the armature-lever, and the metal linings f fin connection with the metal axles t i, and the metal axles t t" in connection with the metal standards K K, and the standards K Kbeing in connection-with the ground-plates w w by the wires Z l, two separate and distinct cir cuits are complete, the batteries Z and Z being separated by the ground-connections, and these ground-connections being complete at m and w and at w and m. The current from the battery Z then passes from the zinc pole that is connected with the ground-plate x to the ground-plate to, which is now the terminus of the platina pole of the battery Z, which remains active in consequence of the zinc and platina poles having their respective ground-conned tions at the ground-plates w and w. The current from the battery Z also passes from its zinc pole, that is connected with the ground-plate w, which is now the terminus of the zinc pole of the battery Z, to its platina pole, that is connected with the ground-plate x. The battery Z also remains active in consequence of the zinc and platina poles having their respective connections with the ground at the groundplates w and 0c, the helices B bein gin the circuit actuated by the battery Z, and the helices 0 being in the circuit actuated by the battery Z, the helices B and 0 having been previously placed sufficiently near the metal arms B B of the armature-lever, so as to require the power of both helices B and O to draw the armature lever from its perpendicular position against the metal points 0 0 the power of the hel= ices B not being suflicient in itself for such purpose without the aid of the helices G, and the power of the helices 0 being insufficient for such purposes withoutthe aid of the helices B 3 but the helices B and G retain the armaturelever in its position against the points 0 0 until the circuit of the battery Z is broken again by separating the point H of the break circuit key 8 from the wire H leading to bat tery Z, which, as soon as done, destroys the attractive power of the helices B, and the helices (3 not being able to retain the armature-lever in its position against the points 0 0 by its power of attraction alone. The weight of the armaturelever at the arm B being equivalent to a spring in this case, causes it'to leave the metal points 0 0 and resume its perpendicular position against the non-conduct= ing points 0 0 thereby breaking the ground connections with the ground w and w, and thereby enabling the helices B and O to assist each other as soon as the point H comes in contact with the wire H, making the con nections between the batteries Z and Z, as heretofore described and explained.
