IMPROVEMENT IN 'PRINTING-TELEGRAPHS.

Specification forming part of Letters Patent No. 76,993, dated Ap1il2l, 1868; Reissue No. 3,810, dated January 25, 1870. a

To all whom it may concern:

Be it known that, EDWARD A. CALAHAN, of Brooklyn, in the county of Kings and State of New York, has invented, made, and applied to use a certain new and useful Improvement in Telegraphic Printing-Instruments for Registering Gold, Stocks, 8m. and the following is declared to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure 1 is a general plan of said apparatus. Fig. 2 is a plan in smaller size, illustrating the manner in which the wires are arranged -said objects in a very reliable manner, and to dispense with the complicated mechanism heretofore made use of to cause an impression to be made when the type-wheel has been brought to a proper position. A magnet and armature are employed in eflectin g the movement of the type-wheel, so that the same is turned to the required position, and then by an independent motion separately controlled from that of the type-wheel the impression is made, so that thetype-wheeltcan remain after it is adjusted or be again moved previous to the impression ein g made. The impression is made on a strip of paper by two type-wheels, so that the printing is in two lines, and the figures and fractions for denoting the prices or quotations are contained upon a wheel and combined therewith. Letters are provided for printing on the same strip of paper to denote the arti- 'cle to which the quotations relate. As the different machines will generally be but a short distance apart, it is preferred to make use of two or more wires communicating through the entire. circuit of machines.. One of these wires transmits the pulsations of electricity that act upon a magnet and adjust the type-wheel to the proper letter or number. The other who transmits the pulsations of electricity, which, acting in a magnet, produce the impression upon the paper. In the drawings three circuit-wires are represented-on e for the alphabet-wheel, another for the number or figure wheel, and the third for giving the impres sion; but the number of wires employed is unlimited.

In the drawings, a is a fin ger-key in the circuit I) to the magnet c.

d is a transmitting-instrument formed with a hand that is moved around from one letter to another, and in so doing makes and breaks the circuit 0 tothe letter-wheel magnet f, giving a pulsation of electricity for each letter.

9 is a transmitting number instrument formed to correspond generally with the letter-transmitting instrument d, and h is the cir cuit thereof to the magnet i of the numben wheel k. y

The finger-key a and dials g and d, being known do not require further description, and it is remarked that the mode of arranging several receiving-instruments in a line, so as to be worked by one battery, is well known, the connections being such that all the magnets are in the-circuits e, and so on.

The type-wheels k and l are provided with the desired letters, numbers, or characters. The wheel k is shown as formed with numerals and fractions for printing the required prices, and the wheel I is provided with the necessary letters of the alphabet, so as to be used in printing names. The mechanism between the magnets and the respective type-wheels being the same, it is only necessary to describe the same on one side of the machine. .The armature an, with its lever 01, swings on the axis 0, and-the amount of motion is regw late-d by the screws 2 and 3, and 4 is a spring to lift the armature and lover.

5 is a pawl on the arm 6 of the armature m,

the wheel 11, and 'r-and's are pawl-arms from Ihe'lever a, taking on opposite sides ofthe wheel q.

It will now be seen that when the armature is attracted by the magnet the pawl 5 turns .the type-wheel one letter by acting on the ratchet p, and at the same time the pawl-arm 1" takes one of the teeth of the reverse ratchet;--

wheel q, rendering it impossible for the momentum to turn the type-wheel too far, and ef- *i'etually blocking the same. As the electrical" circuit is broken and the armature rises the arm s comes against the ratchet q to prevent Thisarrangementefinechanisminsuresgreater accuracy in the movement of the type-wheels, and prevents mistakes when the movement is rapid.

The two type-wheels k and Z, although on separate shafts, stand contiguous to each other, so as to be impressed separately or jointly upon the same strip of paper that is fed alongheneath them, the impression. from the respective wheels forming two difl'erent.

lines of printing.

The means shown for printing are the magnet 0 and finger-key a, sothat whenevereither. or both type-wheels are properly set the fingerkey a is to be closed to operate by the magnet '0 on'the armature t and throw the impression roller or surface it upward, carrying with it the paper strip a: and impressing it upon the type or types.

The roller u (see Fig. 4) is shown as operated ,npon by the hanging pawl 11 to turn the same the amount necessary to feed the paper along, and the pawl '12 on the armatnre-leverframe-t prevents the roller u turning back. The paper is guided in the loops or guides 10, and the motion of the armature is regulated by the screws ll. and 12.

It will now be understood that this apparatus is especially adapted to giving simultaneous'ly at (liffereut.-points: and .withgreat reliability the most recent quotations in theuprice of gold, stocks, or other articles, as the same may be reported ata central station.

I Each ofthe wheels I and I: has a blank space that is turned toward the paper while the other wheel only-is being printed from.

The inking-rollers 2/ 3/..in contact with the respective type-wheels, serve to ink the same.

The roller that feeds the paper along might be operated by ratchet-wheels and pawls similar to those that move the typewheels.

The magnet that gives the impression may be placed directly in the main electric circuit; or it may be operated from the main current by a relay and local circuit. This machine seldom requires attention, except to supply paper from time to time and moisten the inking-rollers, because all the movements of the receiving and registering mechanism are efi'ected by the electricity itself, thus rendering the ma-.

chine entirely automatic.

What is claimed as the invention of said E.

. A. UALAHAN ismotion while the printing is being performed.

'a magnet in one'main circuit, and a magnet in a second main circuit for giving the impression,

1. A type-wheel receiving its motion from in combination with means for moving the paper by the reverse movement of the armature of the magnet of the second maincircuit, substantially as set forth.

2. Two or more type-wheels moving independen'tly and controlled by magnetism,iand arranged so as'to print jointly or separately upon one strip of paper in two or more lines,

substantially as specified.

3. The combination of the type-wheels k and l, magnets fand 'i with the magnet c and impression-roller u or its equivalent, substantially as set forth.

4.. The reverse ratchet-wheel q and stop or i pawl r, in combination with the ratchet-wheel p and pawl 5 for moving and holding the type or character wheel, substantially as set forth.

5. The stop-pawl s, in combination with the armature-lever n, type-wheel l, ratchet-wheel q, and pawl 8 for adjusting or holding the typewheel-in position while the impression is being made, substantially as specified.
