PRINTING-TELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 268,237, dated November 28, 1882.

Application tiled February Q3, 1882. (No model.) Patented in England March 29, 1882;-i11 Austria April T. NS2; in France April 15, 1882; in Belgium April 17, 1882, and in Germany April 1S, 1852.

To all whom it ma 1/ concern Be it known that we, ALBERT F. JOHNSON and FRANK B. JOHNSON, citizens of the United States, residing in the city ot' Brooklyn, in the county of Kings and State of New York, have invented an improved lteceivinglnstrument for Automatic Printing-Telegraphs; and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accoml'ianying` drawings, (on two sheets,) which i'orm a part of this specifica tion. y

This invention relates to improvements in instruments for automatically receiving and printing telegraphic messages, and forms part of the mechanism embraced in our improvements in automatic printing telegraphs, described in our specification marked A, filed simultaneously herewith. In this receiver each kind of letter or character used in transmitting messages is printed through the medium of a separate magnet connected with the transmitting-instrument by a separate line-wire. Ordinarily the messages are sent by passing a perforated strip or sheet of paper through a transmitting-instrument, each perforation in said paper representing a certain specified letter or character, and said transmitting-instrument being provided with devices by means of which each of said perforations brings in to circuit the magnet which prints the particular letter represented by such perforation; but this improved receiver may also be operated directly from the sending-station by means of a keyboard provided with a series of press buttons or knobs, each of which is marked with a particular letter or ch aractcr, and is connected by a line-wire with the magnet that prints such letter er character, so that by successively pressing the knobs in the order in which the letters of the message are found the said magnets on the receiving-instrument will operate to print the same letters in the same order upon a message-strip in said receiver. The message is printed in one continuous line, with suitable spaces between letters and words, upon a strip of paper fed automatically through the instrument, and means are provided for concealing the message by sealing a second strip of paper over the message-strip which contains the printing.

The invention hereby claimed consists in the improved constructions and combinations ot' parts, as hereinafter particularly described.

In the accompanying drawings, Figure l represents a plan view ot' the instrument; Fig. 2, a transverse vertical section through the center; Fig. 3, an elevation ot' part of the feeding mechanism. Fig. 4 is a detail hereinafter explained; Fig. 5, a plan view of a portion ot' a printed message-strip.

Similar letters of reference indicate the same parts in all the several figures.

F represents a series ot' magnets, one coil of each of which is connected with a transmitter at the sending-station by liiiewircs f-L and a series oi' binding-posts, H, and its other coil is connected with a battery and thenceV with the earth through the medium oi' bindingscrews I, iitted upon a copper ring, J, arranged in a convenient position, or as shown in the drawings. rlhe armatures of these magnets are hinged, as shown at It, and their inner ends are prolonged and rest upon the ends of pivoted bent levers L, the lower end of each ct' which carries a printing-type of thc particular letter or character v'hich such magnet is arranged to print when brought into circuit. These levers are pivoted to uprights i, and radially arranged so that the types on their lower ends shall strike on one particular point when ever their upper ends are depressed by the attraction of the armatures of the respective magnets which operate them, that point being' the under side ot' the message-strip G as the latter passes over the under surtaceoi the feedroller N, and they are retracted by suitable springs, O, and thus brought into their normal position when the attraction oi' the armature ceases. The upper ends of these levers L may either be pivoted to the ends ot' the armatures (the [,iivotspassing through elongated slots) or a cap may be secured at the end et' the latter to tit over the end of the levers, as shown at lf3, for the purpose of keeping` them engaged. The uprights M and springs O are insulated from 2 assess 2 the base R. The feed-roller N is xed upon a shaft, N', having bearings in insulated uprights vsecured to the base It,'and the message-strip G' passes over the under surface of said roller from a reel, Q, supported by a standard, Q2, in any suitableposition,andis carriedfrom thence between said feed-roller and afriction-roller, N2, and thence, through a tube or other suitable conductor, N3, to any convenient point.

F'isa magnet,one coil ot' which is connected with a line-wire, f5, by means of a bindingpost, H',its othercoil being connected by means of one of the binding-screws I with the copper ring J, and thence with the local Abattery S'. The armature of this magnet is hinged, as at lr, and to its inner prolonged endis pivoted an upright rod, k2, the upper end of which is provided with a pawl, 705, that rotates a ratchetwheel, l, xed upon one end of the shaft N', so that the feed-roller N is moved forward by each -stroke of said armature for the purpose of leaving spaces ou the message-strip G' between the letters and words on the message, and at the end of the subject-matter ofthe message to leave space between the message and the address.

An inking-ribbon, S, in the form of an endless band, is interposed between the messagestrip G' and the types on the levers L, said ribbon being stretched over rollers S' S' and S2 S2. An inking-roller, S3, is held in contact, by suitable means, with the ribbon S for the purpose of applying ink to the same, and 765 (see Fig. 3) is a pulley provided on the end of one of the rollers S', which is driven by a belt from a similar pulley on the shaft N' for the purpose of imparting motion to said inkingribbon.

lThe ring J is divided at any convenient point,A and its ends connected respectively with the two sections of a switch, R',and from thence with the battery S4 and the earth, for the purpose of throwing the instrument into or out ofcircuit with the sending-station, so that when a message yis to be received and printed l by the instrument the plug R2 of the switch is inserted to bring the same into circuit with the transmitter at the sending-station; and when said plug is withdrawn the currents pass on to the next station which has its receiver in circuit with said sending-station.

In Fig. 4 is shown an elevation of the rear side ofthe pawl and ratchet for rotating the feed-roller; and we may here state that all the magnets and posts, together with other parts through which the currents pass, are insulated from the base R and from the other parts of the instrument.

In order to keep the message secret, a second strip of paper, G2, is sealed over the messagestrip G' by means of the following-described devices: Said second strip, G2, is held upon a reel, Q', supported by a standard, Q3, in any suitable position, and from thence passed between the friction-roller N2 and the messagestrip G' as the latter passes over the feed-roller N. The edges of said message-strip are gummed on that surface which is to receive thevprintin g previously to being placed in the instrument. A cup, N3, containing a moistened sponge arranged to dampen the under side of the edges ot' the strip G2 before the latter passes between the rollers, is suspended from alever, N4, pivoted to any suitable support, and to the opposite end of said lever the plug R2 is pivoted in such manner that whenever said plug is inserted in the switch It' said sponge will be in contact with the edges of the strip G2, as shown in Fig. 2, and the edges of the message-strip having been previously gumvmed, the two strips are sealed together as they pass between the rollers N and N2, with the printing' between them. By these means, whenever the circuits are closed by the insertion of Vthe `plug R2 to receive a message, the cup N3 will be in position to seal the strips together. As the address is printed on the message-strip in the same manner as the subject-matter ofthe message,'it is concealed by the second strip, G2, and it is necessary to provide means for ascertaining the address without the subject of the message being revealed to the person in charge of the receiver. This maybe accomplished as follows: A number ot' arrows or similar marks are printed on the'strip G2 previously to its .being placed in the instrument, for the purpose of indicating in which direction the message is printed, so that the person in charge of the instrument may know from which end of the message-strip the second strip is to be removed in order to ascertain the address, and he removes the same from that end of the strip to the blank space between the message and the address. In order to facilitate the removal ofthe second strip, it may be of thin dark-colored paper, such color admitting of the use of thin paper without the printing being visible through it; and

it may also be perforated along its edges, so as to be readily torn o'. Aportion of a printed strip is shown in Fig. 5.

We are aware that a receiving-instrument having a separate magnet to print each kind of letter or character has heretofore been used, and therefore we do not claim that as our invention.
