IMPROVEMENT IN THE MODE OF MAKING BATTERY CONNECTION WITH AN ELECTRO-MAGNETIC COIL ON THE TRAVELING CARRIAGE OF A TELEGRAPHIC REGISTER.

Specification forming part of Letters Patent No. [0,496, dated February 7,1854.

To all whom it may concern:

Be it known that we, JOHN M. BATOHELDER, of Cambridge, in the county of Middlesex, and MOSES Gr. FARMER, of Salem, in the county of Essezgand State of Massachusetts, have invented anew and useful Improvement in Elec tric Telegraphs or Telegraphic Registers for Reducing and Permanently Recording Telegraphic Signals; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and

- references thereof.

the carriage and thereoording-cylinder are produced, the said section being made 'to represent the main driving-gear on the crank-shaft The operative parts of the mechanism are supported, on a suitable base board or table, A, at or near one end of which is placed the machinery that gives motion to the traversin g platform or carriage B, and to the recordin g-cylinder O, the latter being arranged near the other end of the board A.

The train of wheel-work which operates-the platform and cylinder is mostly contained within a suitable frame, D, and should be so constructed and arranged that when put in operation it may be capable of giving to such parts their proper movements, as will be here. inafter described.

We generally move the platform or carriage" B on its rails F and G aboutone-twelfth of an inch in the same time that the cylinder 0 is made to perform one revolution. We do not,

however, confine our invention to such relative velocities of movement of the cylinder and carriage, as others may be adopted.

The rails F G beforementioned are arranged parallel to each other and made to rest onland extend abovethe base-board A. The carriage 13,,by means of four or any other suitable numberof wheels, (t a, 850., is made to rest and move on these .rails, which are 'constructed of such length as, to permit the carriage to traversca distance equal to the length .of the cylinder 0.

The carriage B supports an electro-magnet, E, that has an armature, I, placed in frontof its'poles and affixed to an arm, K, made to extend upward from a rocker-shaft, L, which is supported in bearings M M situated on the top of the carriage. Another arm,N, projects upward from the sh aft L and supports a stylus or Wire, 0, which is pressed toward the cylinder (J by the action of a spring, P, one end of which is attached to the lower partof the arm N, while the other is affixed to a cord, Q, that is wound on a Windlass-pin, It, sustained by a standard or post, S. By turning the Windlasspin so as to wind the cord on it the. stylus is pressed with greater force towards the cylinder, and, therefore, by means of the Windlasspin and cordthepressure of the stylus against a sheet of paper wrapped around the curved surface of the cylinder may be regulated. 7

Under the stylus a spirit-lamp, T,is placed, as seen in the drawings, its flame being directed upon the stylus so as to heat it while the machine is in operation. I

The cylinder or barrel 0 has itsjournals supported by two posts, U U. One end of it is covered around in a circular path with indjarubber, leather, or other equivalent, as seen at b. Against thisamilled wheel ,V, is pressed by the action of a spring,'W, which is made to bear against a movable standard or arm, X, that sustains one end of the horizontal shaft Y on which the wheel V is fixed. On

the other end of the shaftYis a spur geari, and a ratchet-wheel, k. A spring-pawl, 1, apv plied to the side of the gear 9 engages with the ratchet-wheel. A cord, m, is wound around the barrel '5, and has a weight attached to its lower end. I I

A fan-regulator, n, is aff xed on the top of a vertical shaft, 0, arranged as seen in the drawings. A pinion, 'p, on the shaft 0, is made to engage with a toothed wheel, q, fixed on a shaft, 0', on which there is a pinion, s, that is made to engage with the gear-wheel d.

A gear-wheel, t, is fixed on the inner end of the main shaft h, and is made to engage with another gear-wheel, a, that is supported on the outer end of a rocker-arm, '0, which turns on the shaft h. A small wheel, to, is attached to the wheel a, and is turned with and by'it and made to rest on a rail, at, elevated on the platformor carriage B, as seen in the'drawings. The pressure of the wheel on the rail and the .OtiltlOllS of the wheel will cause the carriage :0 be moved on itsrails in manner as required.

To the under side of the carriage B one end of a system of progressive levers, y y, &c., is jointed or made to turn on a pin, 2, the other end of suchsystem being jointed to the baseboard A, or made to turn on a pin, a the whole being arranged and applied together as seen in the drawings.

A bottom view of the system of levers is shown in Fig. 4. Theirjoint-pins b 0 (H0 f g, 8.20., extend above the levers a short distance.

The battery or circuit wires N P are fastened, respectively, to the pins 1) c thence they both extend to and are wound around the pin (2 thence they respectively extend to and are wound around the pins 0 f thence they are both wound around the pin and so they co'n tinue in the above manner to be applied to all the joint-pins of the series. Finally they are extended to and wound around the magnet or connected with its coil in the usual way. By means of this contrivance, the wires are prevented from being kinked or getting under the wheels of the platform during its movements. When the current of electricity is suffered to flow through the coil of the magnet the armature will be drawn towards the magnet, so as to cause the stylus or wire to be drawn away from the cylinder. As soon as the circuit is broken the stylus is returned against or pressed towards the cylinder by the retractile power of the spring 1?.

Around the curved surface of the cylinder we place or wrap a sheet, h, of paper or other suitable material previously dyed or colored, or chemically prepared, or having a dyed surface capable of being either changed in color or decolorized by the action of heat, or instead thereof .weso prepare the surface of the cylinder, or apply to it such a chemical or other preparation or solution, as will be capable of being either changed in color or decolorized by the action of heat. Many such solutions or chemical matters are known to chemists. The ordinary rose or pinlrcolored tissue-paper of commerce will generally be found to be suitably dyed or prepared for our purpose.

Besides changing the color or decolorizing A, a surface or chemically-prepared material, our

instrument is capable of producing marks or telegraphic signs by burning'or charringv apiece of paper or other proper material. In this respect it differs essentially from the electro-thermic or-e1ectro-caustic telegraph invented by- George H. Horn, and patented on the 25th day of June, A. D. 1850, for in the latter a current of electricityoflowing through a stationary fine platina wire heats the wire to a burning or charring heat, whereas in our telegraphic instruments the markingstylus or burning-wire is heated by a lamp or other means, and is moved towards and away from the paper.

In our invention ormachine the wire may be heated by a separate or secondary current of electricity made to flow th rough it, such wire being moved or actuated by the agency of a main circuit. This combination of parts dili'ers essentially from the electrothermic telegraph of the said Horn, for in Horns invention there is no movement of the stylus or wire toward or from the paper by the agency of an electric or electromagnetic current. The

burning-wire of Horns telegraph is perfectly stationary, and is alternately heated and cooled during the passage of the paper over it. In

our instrument the wire when heated by an electric current is not alternately heated and cooled during its operation, but is constantly maintained at a burning or charring heat or suitable temperature, and by means of a secondary battery and circuit which has no such connection with the primary circuit as a sec ondary and primary circuit must have when used in Horns invention. In this latter the primary electromagnetic circuit must be employed to close the secondary circuit; but in our invention it has no such connection with the secondary circuit, it being independent of it in its operation, and used either to draw the heated stylus away from or towards the paper or cylinder as circumstances may require.

Our invention difi'ers also from that wherein the telegraphic marks are produced on paper or a dyed or chemically-prepared surface by v the direct contact of the electric spark or current, or acid produced thereby, when the said spark or current is made to operate as it does in Bains telegraph.

We do not confine our invention to the abovedescribed modes er machinery for imparting to the platform 13 and the cylinder 0 their respective proper movements, as various other kinds of mechanism may be used for such pur pose.

At each end of the cylinder 0 a spring, i is attached, the same being provided with a lip, k ,which.is so bent as to rest upon and overlap the ends of the sheet of paper h and confine the paper in place on the cylinder.

The paper we have found useful for our telegraphic instruments is known in commerceby the name of English tissue paper, of which various colors may be used, but that which is of a pink shade we have found best ada ted to the purpose, as the discoloration produced by the heat of the marking-wire is of a yellow tint, and is distinctly seen on a pink ground.

It will be observed that the rotary motion of the cylinder and the horizontal motion of the recording-wire cause the line of the marks and dots toassume a helical form. When the sheet of paper is unwrapped from the cylinder these lines will be parallel and may be read like common writing'that is, from left to right'and from the top to the bottom of the page or sheet.

To make the record, we prefer to employ the closed circuit in such manner as to cause it to draw the heated wire away from the paper, using a. spring, or its equivalent, to carry the wire back and keep it up to the paper.

In making the signals, we employ a breakcircuit key as in other electric telegraphs. As the slightest contact of the heated wire with the paper is generally sufficient to produce either, a legible mark or discoloration, and as very little force is required to withdraw the wire from the paper, the circuit, generally speaking, will have ample power to work the instrument without the intervention of alocal or secondary circuit, and a magnetic connection of the two, such as will enable the primary circuit to close the local or secondary one.

In our invention the working-wire may be held back or drawn from the paper by the action of a spring, or its equivalent, and brought or forced in contact with it by the action of the electromagnetic circuit; and we would also remark that instead of an electro-magnet and armatuve'to work the heated. wire a defiectin g needle and coil may be employed.

.7 Fromthe above it will be seen that'a principle of our invention is the application of a heated wire to a chemically-prepared paper or dyed surface, substantially as specified, so as to produce telegraphic marksor signals either by the simple change of color or decolorization of such paper or surface without buring into or through it, as does the electro-thermic or electro-caustic telegraph of Horn; also, that it is a principle of our'invention to produce such mark or marks by charring or burning into a surface, or through paper or other proper substitute by the employment of a heated wire, and by an electromagnetic circuit, makin g it movable toward or away from the moving .paper or substance onwhich the marks are to bemade.

We claim- The combination of the system of progressive levers with the battery-wires, the baseboard, and movable platform, so as to operate substantially as specified and for the purpose set forth.

In testimony whereof we have hereto set our signatures this 8th day of February, A. D.
