lMPR OVEMENTlN 'TELEGRAPHIC SIGNAL APPARATUS;

Specification forming part ofLettersPatent No. 158,7l5, l September 28, 1874.

7 To all whom it may concern:

Be it known that I, JOSEPHWYLKATES, of

Richmonthin the county of Henrico and State".

automatic signal-telegraph to be used in ho-- tels, public departments, large business establishlnents, and also private residences, which shal'ltransmit toacentral supply-station the most frequentlyrecurring wants of the establishment,.and whose operation shall be so simplified as to be adapted to the ordinary intelligence of persons unskilled intelegraphy.

- A grooved drum rests in a hearing at one end, and connected at the other with the main shaft of-a clock-gearing. Within the grooves of said drum are woundnon-conducting tapes, fastenedfto. the drum at one end, and having elongated and round perforations punched within the same, arranged to represent tele graphic letters. These tapes correspond. in number to the most frequen tly recurring wants of: the establishment, and their free ends pass between two metallic rollers or wheels. The lower set of these wheels. have broad faces,- the first one to the leftbeing connected'with the positive pc'le of-the linowire connection, The upper set of wheels are much smaller than the lower set,.and are held down upon the tapes by means of springs, the first one to the right being connected with themegative pole of the line-connection.

- As thetapes are pulled out by hand, and then drawn back by means of the clock-gearin g, the current is alternately made and broken by the contact of the two wheels, through the perforations in the tape, and the appropriatesignal transmitted-to the central supply-oflice. A galvanometer is placed in the apparatus, icon eting-with the lineaFiresand indicates,

box with a pordate'd'January 12, 1875; application filed Q by a tremulous motion, to the operator the employment of thewires by some other instrument, thus enabling him to avoid all confusion of signals Said grooved drum is provided with a stop which limits the motion of the drum.

A loose arbor-wheel on the main shaft is also provided with a stop, which prevents the motion of the clock-gear when the tape is withdrawn, and'also'serves to shunt the. circuit from the operating parts of the apparatus when not in use.- I

' My inventionconsis'ts'in the combination of the above devices, as presented in the claims. I in the drawings, Figures 1 and 4, A represents the grooved drum, r es ting in a bearing,

- B, atone end, and attached to the main shaft 0 of a plock-gearing a theother. D are, the tapes,-i 'astened at one end to the drum, and wound around the same inthe grooves. These tapes correspond in number to the most frequently recurring wants of theestablishment, and are provided with elongated and circular perforations, arranged to represent telegraphic letters. Each one of the said tapes in the same instrument hafsthe first letter alike to indicate the locality, the letters or numbers indicating ,the want being different, as A A, A &c.;

the next instrument, Bl, lZ,-B. at. E is a non-conducting bar, upon which are fastened thesprings F, containing the small wheels G.-

H, Fig. 2, is a'second non-conducting bar, upon which are placedthe metallic supports I, con-v taining-the metallicwheels J. In between these wheels J and the wheels G pass the tapes 1), thelatterterminating outside the box in metallic clips, containing rings K, and the said clips having shoulders which rest in slots in a metallic lace-plate. Z-is the linewire connection for'the incoming current, and M the line-wire connect-ion for the outgoing current. Said post Z' connects,- by means of the wires'a and I), Fig. 1, with the first of the springs F, and, through the wheel, with the supports I. N, Figs. 1-, 2, and, 3, are wires connecting the support of the first of wheels J with the spring F of the second wheel G,

, &c., the last of these supports 1 'comnuinicat- 'ing with the post 0 upon the metallic frame of the clock-gearing through the wire 0. 1

Figs. 2and' 1. is a clock-spring, and Q a ratchet-wheehniade fast to shaftO attachedftd the drum is a loose wheel',-bearing a pawl, and meshing with a spur-gear and 11y. Said wheel It hasa stud, cl, which moves readily in one direction under-- an insulated catch,-:-S, but is'opposedbyfa notch in the latter'when moved in an opposite direction. Said catchconnect's, through a; .spring, T,- with the postZ, and serves, through'stud d; to, shunt the circuit from"the Operating partsiwhen not'in use. v81nd stud d opposes the motion of wheel R when the tape is withdrawn, and the shunting of the opera-t ing :parts is maintained until-the tapeis'released. U, Figs. 1 and 3, is a galvanometer,

spaces beneath the grooves of the drum into recesses, which, when a signal is sent,.receive the relaxed folds of theother tapes, andpre vent the same from becomingdisplaced or tangled.

The operation of this-apparatus is as follows: The instrument is supposed to be set up at a station, and to be connected at a central supply-oflice with a relay-magnet, Morse register, or sounder. Now, when the apparatus is not in operation the current comes in at post Z, passes along wire 'a through-the metallic frame of the clock-gearii lg-dowu wire a through thecoils of the .galvanometer, and out wire y to the post M, theonlymanifestation ot the same appearing in the needle of. the galvanometer, which, if the-current be broken by some other instrument, becomesagitated in its endeavors 'to dispose itself transversely to the currcntin the'coils, obedient to certain laws of magnetism. lf the needle is, therefore, in motion, to avoid confusion of signals, the operator must wait until it becomesquiet, as its treniuious motion indicates the employment of the wires by some other instrument. "Now, if a carriage is.

is transmitted through thennbroken eonnection of the metallic conductors F,JG, I, J, and N, out to post M through-cs3 g Having thus described my invention, what I claim as new isv I 1. The combination of the pertorated nOnconducting tapes D, with a grooved drum, A, placed upon one and the samesh'uft with the mainspring of a clock geariugso constructed and arranged that the withdrawal of the tapes winds up the spring, andthe reaction of the spring, when thetapes are released, winds up signals, substantially as described.
