SPECIFICATION forming part of Letters Patent No. 693,390, dated February 18, 1902. ' Application filed October 19,1886- Serial No. 216,682. (No model.) To (555 whom, it may concern.- Be it known that I, FELIX BENEDLCT Ilsa- ZOG, a citizen of the United States, and aresident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Electric Signaling Apparatus, (Case No. 36,) of which the following is a specification. In United States Letters Patent Nos. 289,83t and 292,115 and in numerous subsequent patents and applications I have shown various forms and constructions of signal-transmitting apparatus differing broadly from all previous inventions in that the signal to be transmitted is not sentat the instant of setting nor operated by the transmitting operator solely, but requires some'additional cooperation of mechanism at the receiving-station before it transmits its signal. The transmitter shown in the present new system and organization is of this general character. Figure 1 represents thistransmitter. Fig. 2 shows a detail of its construction and attachment in circuit; Fig. 3, a modification thereof; Fig. 4, an enlarged view of a detail; Fig. 5, a general view of the system as well as of my novel annunciator and signal-receiving mechanism; Fig. 6, an enlarged view of this signalreceiving mechanism; Fig. 7, another form thereof. In Fig. l, A is a reel operated by a clockwork-train B D and carrying a roll of paper or metal tape which has been previously perforated, embossed, or dotted with an insulating-ink or otherwise suitably prepared in a manner usual in a well-known branch of automatic telegraphy. This reel operating clockwork can be wound and remains wound until it is permitted to operate by the withdrawal of a detent, which engages with a su itable part of its mechanism, (in this case the notched disk D.) The detent'is released by the operation of the armature-lever L of the magnet M when the latter is energized by a closure of the circuitand insertion of sufficient battery at the receiving-station after the entire transmitting apparatus has been put in circuit by the closure of the switchlever 2, Fig. 2. As soon as this detent is removed the reel begins to roll up the paper, (or, if desired, it may be made to feed out the paper which is held closely or is drawn up by a second drum, not shown,) or the clockwork may operate suitable pawl and ratchet or friction'roller, or any other suitable and wellknown device to be used for the purpose. The circuit after passing through the magnet passes into the contact bed or bracketF and themes, as the respective perforations pass, into the metal screw (J to the return-wire or ground, as the case may be. The mechanism may be so organized that the message-tape is of about the length to be entirely carried along by one winding of the spring, or, if preferred, it may be much shorter, in which case it is desirable not to waste the spring energy, which waste may be prevented as shown that is, for instance, by causing the disk D' to revolve once for a certain length of tapeand if there be no perforation or equivalent, and hence no closure of the circuit during this time, then the armature-lever will fall into the notch in the disk and stop the movement. If desired, an electromotor, either in local or inshunt circuit, (as elsewhere shown by me,) may be employed to feed the tape in place of the clockwork. InFig. 5 is seen my new annunciator, as follows: A metal drum is covered. by a sheet of paper G, held in place by adjustable rings or other suitable means. (Not shown.) This paper is of such character as is usually employed in automatic electrochemical telegraph-receiving apparatus and is kept moist partly by its capillarity and partly by being from time to time rotated on its arbor so that its surface passes through the solution in the trough H, which contains solutions such as iodid or ferrocyanid of potassium or other solutions, such as are well known in electrochemical telegraph receivers. Cooperating with this solution moistened paper on its metal drum is a stylus or spring of iron, tin, platina, tellurium, or ruthenium, 850., so placed that when a current passes through the paper from the stylus to the drum itleaves a mark on the paper. Any of the well-known cooperating solutions and terminals in electrochemical telegraphy may be used, and of course it is understood that where a stylus is used which is decomposed by the current without the presence of a moist paper, or Where the moisture is not required for the purpose of lessening the resistance,the trough is dispensed with; or the paper may be covered with a hygroscopic solution. There is a stylus K for each and every terminal and transmitter X at the distant station,and these are mounted on an insulating-frame J. To the spindle carrying the paper-mounted drum is fastened a ratchet-wheel T, which is operated step by step at each depression of the pawl-knob V, and this at each depression of this knob turns the drum sufficiently for the operator to observe the space which till then had been under the stylus-pointthat is, about one-quarter to one-half inch. Each line comprises a spring-jack W, and cooperating with the pin thereof are a hollow plug and a flexible cord, terminating in the battery and thence leading to the return-wire. In this cord or circuit is looped the receiving-pencil instrument 0,. which can be made in various forms, but which in the instance shown in Fig. 6 consists, essentially, of a hollow tube 0, to the upper end of which is fastened a small sounder or diaphragm or electric bell E, the operatingmagnet F of which soundproducinginstrument is in the circuit of the flexible cord; but this circuit is broken within the tube and can only be completed by pressure upon the pencil-point D. This pencil is an ordinary lead-pencil or pen or writingpoint of any desired character fastened into a rod, which has on it a collar against which bears acylinder-spring. A metal cap with a hole sufficiently large to permit the pencil to move freely up and down within it, but not large enough to permit the spring-retaining collar to protrude, keeps the parts together. A modification of this instrument, in which the circuit is closed by means of a switch operated by the pressure of the fingers on the pencil instead of by the pressure of the penoil on the paper, is made by me the subject of another application. The operation of the parts above described is as follows: The sending operator adjusts the message-tape, (perforated beforehand in any suitable manner,) winds the feed-train, and closes the switch-lever 2, thereby closing the circuit through the corresponding stylus K, the sheet of paper G, metal drum-frame, bell B, and battery L. The resistance of the paper on the drum is so great that the magnet M is not energized, and hence the clockwork is not released. The receiving operator presses knob V once, and thereby causes the drum to rotate sufficiently to perceive clearly the discoloration made by the current in the place occupied by the stylus corresponding to the operated line. He thereupon inserts the plug Y in the corresponding spring-jack W, and thus completes the line, with the exception of the break within the receiving instrument. By pressing the point of the tube to paper the circuit is completed, and a current sutficiently strong to release the mechanism of X causes the paper to be fed, and the circuit will thereupon be controlled by the perforations in the tape. The object of the pencil instrument is so that a means of record ing the ticks as they come in is always at hand without dangerof being out of orderor of requiring delicate adjustment. These ticks or breaks are heard on the audible receiving instrument on the bell, (or, if desired, this is placed elsewhere, as it is merely for convenience s0 placed,) and as these are counted the number of the breaks in each group can easily and rapidly be recorded in numerals instead of being thereafter counted as spots or spaces on a printing-register tape. The contacts within the tube are so arranged that the pressure on the writing-point may vary considerably without breaking the circuit. Figs. 2, 3, and 7 show details and variations of what has already been described. Fig. 2 shows a plate of wood, iron, or other suitable material which is fastened to a stand or a wall, and the terminal wires for the signaling instrument are connected to metal plates G. Attached to corresponding points in the framework of the signaling instruments are other pieces of metal H, which form the terminals of the circuits in the instrument. At each corner are seen screw-holes P, by means of which the back plate and the frame can be fastened together, and when so fastened the circuit connections are automatically made without further necessity for putting wires in binding-screws or making splices, &c. If the parts are made interchangeable, a further advantage lies in the fact that new instruments can be quickly and safely inserted by those ignorant of the circuits and connections. In Fig. 8 there is a modification of this back contact, which of course is equally applicable to signal-receiving apparatus, and in another application I show a construction thereof wherein the contact also serves to hold the parts together. Fig. 3 is a modification of the signal-transmitter of Fig. l. A step-by-step-actuated electromotor takes the place of the clockwork and IIO the signals are received at the receiving-station in a manner analogous to that shown in before-mentioned Patent No. 292,115 and in a pending application for a district-box. At each demagnetization of the magnet M the ratchet-wheel J is moved one step and carries with it the gear-wheel meshing with a rack L, which causes this to move one step, and during this progression the contact brush or point S is carried over the character-blocks N,(enlarged in Fig. 4,) and thus transmits to the receiving operator signals at each break, which is caused whenever a notch in N passes under S. These pieces N can be inserted at will bythe operator, and thus the signals may be varied. Of course it is evident that the messagetransmitting mechanisms of Figs. 1 and 3 are interchangeable, the pertinent essential feature of difference being that the apparatus shown in Fig. 1 is operated after a single impulse from the receiving-station, while that of Fig. 3 requires as many receiving-impulses as there are individual signals or parts of signals. 1 Fig. 7 is another instance ofand a modification of the signal-receiver of Fig. 6. A slide P is carried on "a horizontal bar insulated from the metal bed R, on which rests a strip or cord of chemically prepared paper S. In the slide P is drilled a hole, loosely fitting within which is carried the stylus N, of suitable metal, chemically cooperating with the solution in which the paper has been moistened to form discolored (lots or dashes wherever they touch whenever-the circuit is closed. The weight of this pin N is'sufficient to cause it to drop upon the paper with sufficient force to close the circuit at the paper, or, if preferred, a weak spring may be made to do this. The pin-carrying slide P is fastened to a cord, the other end of which is wound around a coiled spring-drum O, which is prevented from running down too rapidly when the spring is wound by the train and fan escapement shown. hen it has run down, it brings the stylus-point to rest upon the rubber block R,thus breaking the circuit. The operation of this recorder is as follows: When the operator wishes to cause the distant signal to transmit and this receiver to record, he grasps the pin and, lifting it slightly,(so as to keep the point from the paper,) he draws it to the end of the rod Q and permits it to drop and at the same time to be drawn back by the cord and train. As it drops it closes the circuit, and as it is drawn back uniformly it produces a record of the dots and dashes. In practice I prefer to put the stylus of the annunciator within an inch of the surface of the liquid in the trough, as then the capillarity of the paper will keep it sufficiently moist, and by the time the rotation has brought a spot once more under the stylus the former marks will have faded, so as not to interfere with the later ones. A glass frame covers the annunciators. What I claim is 1. An electrolytic receiver comprising a cylinder-su rface and a bath-reservoir cooperating with a portion only of the surface. 2.
