AUTOGRAPHIC TELEGRAPH.

.SPECIFICATION forming part of Letters Patent No. 305,259, dated September 16, 1884.

Application filed November 2, 1883. (No model.)

To all whom, it may concern,.-

Be it known that I, MICHAEL HOFFMAN \VILsoN, of Brooklyn, in the county of -Kings and State of New York, have invented a new 4 5 and useful Iniprovementin Autographie Tele which is externa-'l to the main circuit, is ar- 2O ranged to move between and in contact with the interrupted lends of the branch wires, and

thereby to close the circuit through said branch v wires and to the main-line wire successively.

According to my present inventionI em- 2 5 ploy branch wires which are continuous from end to end, and a cgmmutator adapted to make contact with the ends of the branch wires succcssively, and arranged in the main circuit, the main-line wire being connected with the 3o commutator-hub or its shaft. 1 In autegrapliic telegraphs of the hind described it is of great importance that the commutatore of the two or more instruments in the line rotate synchronously; and my invention further consists ina novel combination of parts in a unison apparatus, whereby the closing and breaking of the main circuit by the non-conducting or insulating ink on the form passing into and out of contact with 4o the terminals of the branch wires will automatically and synchronously effect the starting and stopping of the commutators of all the instruments on thei line. Such unison apparatus is also applicable to the machine 4 5 shown in my aforesaid application.

In the accompanying drawings, Figure l is a vertical longitudinal section of an instrument embodying my invention, and Fig. 2 is an yend relevation of such parts of the machine 5o as are necessary to illustrate the unison apparatus. v

Similar letters of reference dcsignatecorre spending parts in both figures.

A designates the basepiece or bed of the instrument, and B designates the table supported thereon by pillars A.

Below the table B are arranged the branch wires or conductors a, which are placed side by side, as in my aforesaid application, and are secured to bars-b of insulating material. The terminals a of these branch wires project upward through an aperture, c, in the table B, and are arranged in two rows across the table, the terminals in each row being opposite the spaces between the terminals of the other row'. The branch wires or conductors (l, may be of any suitable character.

'Immediately over the aperture c in the table is arranged the cylinder D, which may be of copper, and is located in the electric circuit.

The form on which is delineated the writing or other matter to be reproduced may be of paper or other suitable material, and the writ ing `or other matter may be delineated in a non-conducting ink. 4

In the transmitting-instrument the paper ou which messages are written may be in sheets, or in the form of a strip, E; but in the receiving-instrument the reproduction may be ob- SO tained on a continuous strip of paper, E,which may be wound upon a drum or reel, E', being drawn thereto over a guide-roller, El.

The cylinder D is rotated to transmit messages, and wheels or rollers may be made to rotate by frictional contact with the -cylinder, as shown and described in my aforesaid application, so as to feedthe paper along. These wheels or rollers are not here shown, as they form no part of this invention. The form E being carried over the terminals a', the circuit from the cylinder to the branch wires a is broken repeatedly by the characters in nonconducting ink. The branch wires a diverge at the end of the tableB, and are secured at a proper distance apart in a semicireular or are-shaped support or frame, F,which should be of insulating material.

Gr designates a commutator mounted loosely upon a rotary shaft, G', but in electric comroo munication with said shaft. The commuwtator y carries brushes d, which make contact successively with the terminals fr ot' the branch wires a, and to the shalt G is attached the line wire c. Thus itwill be seen that when a conducting part ol" the form E is in contact with the terminals c and the commutator is rotated the circuit is closed from the cylinder D through the branch wires a, the commutator G, shaft G, and line-wire c. It will therefore be seen that in .my present instrument the commutator is in the main circuit, while in Amy former application, above referred to, the branch wires were interrupted or divided, and the commutator was rotated between the in terrupted ends ot' the branch wires, so as to close the circuit through them successively, and was not itseli` in the electric circuit.

The cylinder D and the commutator-shaft may be rotated by any suitable mechanism. As here shown, the connnutator-shatt G is connected by a coupling,f, to a longitudinal shaft, H, which is in line with it, and which is supported in bearings g.

The two parts of the coupling f are represented as separated by insulation j", and the shaft G is mounted in a bearing, g, which is insulated from the base-piece or bed A.

I designates a large bevel-wheel, and 71 a ybevel-pinion, which are formed integral or rigidly connected, and which rotate on a iiXed stud, h. The wheel I gears with a pinion, h2, on the shaft H, and the pinion Zi gears into a large wheel, I', mounted on a shaft, h. The shaft Zr carries a pinion, 7i", which gears into a large wheel, I`, on the shaft of the cylinder D.

The mechanism described, while transmitting a slow rotation to the cylinder D, will rotate the commutator-shaft very rapidly. The cylinder D and shaft II G are intended to be constantly rotated by clock-work or any other suitable motor. (Not here shown.) I will now describe the unison apparatus, which is best shown in Fig. 2, but also in Fig. l. As before stated, the commutator G is loose upon its shaft G', although it is in electric communication therewith, and to the outer side of the commutator is secured a disk, J, in the edge of which are two notches, t'.

K designates a collar iixed on the shaft,and connected with it a ratchetwheel, L. The disk J and wheel L are represented as insulated from the commutator G and collar K, rubber or other insulation, j, being between them, and said disk and wheel, by said insulation, are out of electric 'communication with the shaft G.

To the disk J is pivoted a pawl, 71.', which, by a spring, lz, is held in engagement with the ratchet-wheel L when not otherwise actuated.

In the line-wire c, which connects with the commutator-shat't G", is a magnet, L, which vis energized whenever the main circuit is closed it' the instrument is intended for work ing on a closed circuit.

At each instrument is a local circuit, Z,which includes a battery, Z, and a magnet, Z2, and one end of which is connected with a contact-piece, Z, while the other end is connected with the 'a-rmature, mi, which answers for thc local magnctZ'l. The lever M also carries a toe erprojcction, mi, for acting` 011 the pawl Zt, to disengage it from the ratchet-wheel L. XVhen the vaction ofthe local magnet Z2 ceases, the lever M is pulled down by a spring, fm'.

From the foregoing description itwill be understood that as long as the pawl k is held out of engagement with theV ratchet-wheel L the shaft H G will rotate independently of the commutator Y the commutator being held against turning by the stop-pawl in engaging with one ot' the notches or stops Z in the disk J. This condition is maintained until the forni is introduced between the rotary cylinder D and the terminals a, and the writing, in insulating or non-conducting ink, comes into contact with said terminals. As soon as this occurs, the circuit through the main line c and magnet L is broken, the armature-lever Z is released, and at once moved by the spring away from the contact Z. The local circuit Z being thus broken, the spring in" draws down the lever M, thereby moving tlie'stop-pawl n1. away from the disk J and the teem away from the pawl 7,:,whereupon the spring 7i throws the pawl 7.: into engagement with the ratchet-wheel L, and through said `pawl the said wheel L rotates the disk J and commutator G. As soon as the insulating or non-conducting ink on the form passes the terminals a, the circuit through the main line c and magnet L is closed, and the magnet L is energized and attracts the lcver Z, to cause it to make contact with Z, and thus close the local circuit Z. By the currentthrough the local circuit the magnet is en ergized and attracts the lever M, thereby causing the toe m3 to disengage the pawl k from the ratchet-wheel L and bringing the stop-pawl on` into one of the notches Z on the disk J. The commutator is thus released from its operating mechanism and brought to rest, where it remains until the insulating-ink of the form again reaches the terminals a. Thus it will be seen that the commutators of the instruments in the main line c are all brought to a common starting-point and are simultaneously released when each line of writing' on the form comes in contact with the terminals a.

rIheinstruments are arranged and connected for operation as shown and described in my aforesaid application, one instrument being-at each end ot' the line, and each instrument serving both for receiving and transmitting.

The ratchet-wheel L and the pawl and disk k J constitute a clutch-connection between the commutator and its shaft, and the lever M, with the stop-pawl n1., forms a stop mechanism operated by the closing of the local circuit.

That I claim as my invention, and desire to secure by Letters Patent, is-
