T0 at whom it may concern:

1 Be it known that I, J OSEPH KoLzER, a subject of the King of Prussia, residing at Duisburg, in the Kingdom of Prussia, German Empire, have invented new and useful Improve ments in Telegraphic Apparatus, (for which I have obtained patents as follows: in Great Britain, N o. 8, 990, dated June 14, 1884; in Belgium, No. 65,449, dated June 11, 1884; in

1884,) of which the following is a specification.

My invention relates to improvements in telegraphic apparatus whereby messages can be transmitted from stations in one main line to stations in a second main line.

In carrying out my invention I make use of relays of special construction, such as are de-' scribed in my prior application filed August 14, 1884, Serial N 0. 140,597, an arrangement of circuitclosing keys, registers, a novel commutator, and connections between the main lines, whereby the above-mentioned result is accomplished, all of which is more fully pointed out in the following specification and claim, and illustrated in the accompanying drawings, in which" Figure 1 represents a plan view of the operating parts and connections; and Fig. 2 is a perspective view, on a larger scale than the preceding figure, of a relay.

In the drawings, the letters M N and O W respectively designate the two main lines. V is the central or connecting station. R and R are the relays thereof. S is a register. B B are the batteries in the lines. T isa fingerkey of the connecting station V, and U a'commutator, all arranged as shown.

The armature-lever O of the relay R is provided with an extension, 0, having thereon a head-piece, a,vwhich projects upward and is bent over to form a hook, on the end of which;

stops, the latter having an insulated point. j

is a button or stud, which projects from the insulating-layer 0 andforms a stop for the spring-arm i, so that the entire surface of the lattercannot bearupon the insulating-layer. The spring-arm i is connected, by a spiral spring, 9', to a binding-post, h, insulated from k, which the relay R, andthe said spring is made of' very thin wire, so that it can yield to the move 4 ment of the armature-lever 0 without retarding the said motion.

' The armature lever 0 of the relay R is con-. struct-ed and arranged as the armature-lever of these t o Morse relays,or by two polarized relays similarly constructed,in combinationwith suitable connections, the sideward connection of the two main-line circuits 0 W andMN approaching one another is effected. A part 'thcrelay R, just described. By the use of of the line-battery is short circuited, so that I no special local battery is necessary. The posilion of the point of connectionof the main line depends onlyon the reciprocal position of the circuitsto be united, and must be so chosen,

if possible, that the circuits are divided into' equal parts. By this sideward connection of thetwo main lines is simultaneously produced both the possibility of a sideward transmission from a main-line circuit to amain-line circuit and the lengthwise transmission from a mainline circuit to a main-line circuit. The first is accomplished by separating at the point of connection one branch of one of the main cirand the latter is accomplished if at the point of connection the easterly branch of one mainline circuit and the westerly branch of the other line-circuit are conducted to the ground.

The two main lines M N and O Ware, con- 7 nected with each other at thecentral station,

V, and for transmitting a message-say from M of the circuit M N is separated and cona station in the main line M N to the main line 0 W-the holes III and IV of the commutator U are plugged, and to disconnect the lines the plugs are removed from holes III and IV and inserted in holes I and II. In the latter case the batteries B B remain in the line circuit. When'the holes III and IV of the commutator U are plugged, as before stated, to throw the main lines in communication with each other, and all the finger-keys are in their nor mal or open position, the current in the linecircuit M N takes the following course: from a point, N,' in the line to commutator U, over plate 1 thereof to wire 1, through armaturelever O of relay R, contact 70, spring-arm 0;, spring binding-screw h,the coils of relay B, through wire 2,and back to plate 5 of the commutator, through the medium of wire 3. From plate 5 the current passes overplugged hole IV to plate 6, and from thence to one pole of the battery B through wire 4, and continues in the circuit M Nalong wire 5, while from the other pole of the battery B the current flows.

in a direction from pointO in the line 0 Wto plate 4 of the commutator II, over plate 4, through wire 6 to the armature-lever O C of the relay B, through contact k, spring-arm 6, spring 9, binding-post h to relay B, through the wire 7. The currentcpasses through the coils of this relay and returns to the commutator through wire 8, which is connected with plate 2, and then over plate 2, plugged hole III, plate 3, through wire 9 to one pole of battery B, through wire 10 to the register S, through wire 11 to the finger-keys T, and continues in the line 0 WV along wire 12. I

If a key is depressed in any station on the line M N, the writing or registering instruments in all the stations on the line 0 WV are actuated. For instance, if at the station V a finger-key is depressed, all the armature-levers of the receiving-instruments in the circuit 0 W fall off, the armaturelever of the relay R at station V is attracted, and closes first, -by means of spring-arm i and stop I, the local circuit of battery B to relay B, so that the position of the armature-lever C G of the latter remains unchanged from the position shown in the drawings, and only after this can the current pass through the contact k to springarm 5, whereby the current is broken in linecircuit M N. All the instruments in the stations on the mainlines M N and O Ware consequently set in operation. When the finger-key at the station V is released and thereby thrown out of contact, the current is reestablished in the main line 0 W, as the contact through 73 k at relay R had not been broken previously. The armature-lever GO returns to its normal position, whereby the circuit M N is first closed by contact k and spring-arm z, and the 1 Witnesses: local current through spring-arm 'i and stop Z WALTER H. SCHULZ, is broken. If it be conceived that the branch CARL BADE.

ducted to the ground at the station V, I have in the remaining lines of the circuit 0 W and N a sidewise translation from a main line, 0

W, to a main-line current, N.

If the branches M and W of the two main lines M N and O W are separated at station V and grounded, I have in the remaining line, 0 N, the. lengthwise translation from a main-line circuit to a main-line circuit. The Morse or polarized relays previously described can be replaced by Morse registers, the anchorlevers of which are constructed in a. similar manner as those of the relays. The registers in this case perform both the function of writing and transmitting.

The commutator used and necessary in the abo v e described arrangement consists of a base and six plates, 1, 2, 3, 4, 5, and 6, and plates 3 and 4 are separated by a hole, I, plates 1 and 6 by a hole, II, plates 2 and 3 by a hole, III, and plates 5 and 6 by a hole, IV. The

holes separating plates 3 and 4 and plates 1 .No. 140,597, filed August 14, 1884, and in my Patents No. 311,330, dated January- 27, 1885, and March 9, 1886, No. 337,590, shown telegraphic apparatus whereby messages can be transmitted from a remote station in a main line to a remote station in a branch line, from a remote station in a branch line to a remote station in a main line, and also from a station on a branch line to a home or receiving station that has been disconnected froma main line.

The presentinvention differs from the above so far as the special arrangement of the circuits and form of the commutatoris concerned, and relates altogether to the means whereby messages can be transmitted over two wires.

What I claim as new, and desire to secure by Letters Patent, is

In a telegraph apparatus, the combination,

JOSEPH KOLZER.
