IMPROVEMENT IN PRlNTlNG-TELEGRAPHS.

Specification forming part of Letters Patent No. 137,117, dated March 25, 1873.

To all whom it may concern:

Be it known that I, OHARLEs J. WILEY, of the city, county, and State of New York, have invented new and useful Improvements in the Telegraph for Printing Stock and Gold Reports, of which the following is a description, reference being had to the drawing accompanying and making part of this specification.

My improvements have reference to that class of telegraphic instruments used in print ing stock and gold reports in private lines; and the nature of my invention consists, first, in operating the printing-cylinders by the same wire and circuit or magnets so as toprint from the cylinder having the alphabet, or the one having the numerals, as desired, the motion of the one cylinder being arrested while the other is being rotated; secondly, in the construction and arrangement of the devices by which the motion or rotation of the cylinder is arrested and suspended while the other is in motion, and for automatically shifting the rotation from one cylinder to the other, as desired thirdly, in the arrangement of the ratchets, pawls,detents, and springs for regulating and rendering precise and accurate the stepby-step motion of the cylinders; fourthly, in regulating and guiding the paper ribbon to be printed by means of a peculiar guide-frame and plate, which enable the paper ribbon to pass smoothly and easily from the feeding mechanism; fifthly, in a novel mechanism for the feeding and guiding the paper ribbon as it is impressed in printing.

In the accompanying drawing, Figure 1 represents a plan view of the instrument. Fig. 2 represents an end elevation of the same. Fig. 3 represents a side elevation of the same. as seen from a vertical section at line A B of Fig. l.

In all the figures similar letters represent similar parts of the instrument.

The drawingrepresen ts an instrument adapted to setting or adjusting itself to one letter or number from the point of stopping; but the capacity may be increased by enlarging the diameter of the cylinders and blanks at the slots. The working parts of the instrument are mounted upon a circular base or platform of hard wood, 0, of the usual form. Upon the platform are secured the two electro-magnets, D D, the wires of which, d, are connected with the wires of the main circuit, and allow the current to pass from one to the other. Upon opposite sides of the base are arranged the two parallel pairs of magnets, E E EE, the conducting-wire of which, 0, is so arranged as to allow the transmitting the current to all the magnets E at the same time. 0 are firmly secured the two equal parallel frames, G G, which, rising vertically to a suit able height, bend forward in a horizontal direction and support, upon suitable bearings, the supporting-shafts F F of the two hollow type or printing cylinders, H H. Between each pair of the frames G are hung the double ratchets I I fast upon the shafts or axles F F. Between the pairs of frames j j are the armature-vibrating levers J J, one end of which holds the steel armature-attracting plates j j, each extending over both magnetsE E, and

upon which the magnets act; and the other end carries the double or forked pawls l 1, fitted to mesh into the side teeth of the ratchet I. These ratchets are provided, both, with the side teeth, and also with teeth upon their peripheries; and each side tooth, when acted upon bythe vibrating armature-levers J J and spring-pawls 1 1, turns the shaft and type-cylinders by a step-by-step movement, so as to move forward a letter or number one step to ward the printing-pad. Attached to each of these ratchets is a forked detent spring, 2 2,

or click, which catches intoa tooth on each side i of the ratchet at each vibration of the lever. Another detent, 3, passes between the forks of 2, .falls into the periphery-teeth after each vibration of the armature-leversJ and another detent, 4, passes under the ratchet and hooks into the periphery-teeth, so as to arrest the movement of the ratchet at the exact distance of the step-by-step movement. These pawls and detents are all attached to the armature-levers J J so as to act and react with the vibration ofthe levers. 5 5 are spiral springs of the usual form for accelerating the vibration of the levers. H H, Figs. 2 3, are two hollow parallel and similar type or printing cylinders, which, being attached to axes FF, respectively, derive their movement from them and the pawls and ratchets above described. These cylinders are placed side by side, but leaving a small open space between their inner edges. Their outer ends are closed, but at the oppo- Upon the base site end they are open'so as to form an open space within from end to end. Suspended from the cross-shaft K, which is supported by the two vertical side bearings, K, secured to the frames G, is the fixed central arm L, which is flat and thin, so as to pass between the inner edge of the peripheries of the two cylinders. To the lower end of arm L is jointed the horizontal vibrating arm M, which is bent downward at each end, so as to form dogs or downward-projecting prongs m m, as shown in Fig. 2, the exterior of the cylinder being partly left off in the drawing to show the form and arrangement of this device. The cylinders H H are provided with two'open parallel and equal slots, or longitudinal openings in their peripheries, so as to permit the projecting prongs m m to pass through them to just outside the peripheries, alternately, as the arm is vibrated by the driver, hereinafter described. Upon the inner edges of the peripheries of each of the cylinders are projecting rings or flanges h h, one of which has upon the outer surface or periphery the letters of the alphabet, and the other the numbers from 1 to 0, and their fractional parts, arranged for 1')rinting, at equal distances apart, as partly shown in Fig. 2. The purpose of the vibrating arm M, and slots in the cylinder, and their operation, are now to be described.

Upon the cross-shaft N, (Fig. 1,) supported in fixed upright bearings, are suspended the two similar horizontal vibrating armaturelevers, O 0, to one end of which are attached the attracting steel plates a a, over the magnets by which they are operated, and the other end of these levers extend under the typecylinders H H, and continue outward, so as to operate the paper-feeding mechanism. Directly under the vertical center lines of the cylinders is the round flat table P, supported on the upright standard 19. Above this table are two arms,6 6, secured to the inner faces of the armature-levers 0 O, and projecting horizontally inward at right angles to the levers, so as to nearly meet. These arms support the two projecting pads 7 7, which are thus, respectively, directly under the rings of the cylinders which carry the types for the letters or numbers. 8 8 are two uprights, one under each of the levers O, and being provided with rotary heads and screw-spindles r, (Fig. 3,) working in the uprights, the adjustment of the position and downward movement of the levers is regulated with exactness, and the amount of pressure of the armature-levers upon the swinging bar, next herein described, in connection with the vertical springs. Between the upper surface of the table 1? and the arms 6 6 is hinged upon a central pivot the vibrating plate 9. At each end of the vibrating plate are secured the brackets 10 10, projectingoutward and upward. Upon thearmaturelevers 0 O are placed the two sliding boxes 11 11, which are slotted, and a stud with a head fixed on the upper side of the armaturelevers, within the slot, holds the box and limits its movement to the length of the slot, the length of the slot corresponding with the ex-. tent of the movement of the boxes. These boxes carry each a projecting head, 12, which alternately act upon one or the other of the prongs m m of vibrating arm M, when opposite the slot in the cylinder, before described. Upon the axes of the cylinders, on each side, are secured the two tapering operating pins or fingers, 13 13, which are carried round with the axles and cylinders, their outer ends extending down far enough to come in contact with the projections 10 10, and thereby to vibrate the arm 9 when required. These pins or fingers must be always in a line with the slots of the cylinders so as always to indicate their position. Two vertical pins, 14: 14, are secured in the base of ,the instrument, which are placed so that when the pins 13 13 are vertically downward they will be directly over the fixed pins 14 14. The inking-roller s is carried by the two movable brackets s s, hinged to the cross-bar K, and rests by its own weight upon the type-rings when in action, and rotates with the cylinders, and may be thrown back when necessary in .the usual manner. The paper ribbon, on which the printing is to be impressed, passes between suitable guides on the armature-levers O, and between the printing-pads 7 7 and the cylinder-rings, and isconducted thence to the feeding mechanism, which consists of the feeding-wheel 15, to which is fixed a smaller ratchet, 16, to which is attached a springdetent, the two ratchet-wheels 17 17, and springlS, which are operated by the pa-wls 19, which is operated by vibrating arm 20, connected by rod 21 withthe armature-levers, and so that the feeding-wheel will be turned by the movement of either or both of the armature-levers. Extending over the feedingwheel is a spring pressure-plate, 22, by which the paper is kept to the feeding-wheel by a gentle yielding pressure. The feeding-wheel is turned the distance of a tooth of the ratchet at each release of the attracting armatureplate from the magnets, when the ends of the levers at the feeding device descend. A square frame, 23, (Fig. 2,) of the width of the paper ribbon, supports on the top the pressure plate or spring 22, and forms a guide-within which the paper ribbon passes smoothly and easily away from the feeding mechanism.

Having thus described the mechanical parts I of my invention, Inow proceed to describe the manner of setting and operating the same. Before commencing the printing I place the two printing-cylinders H H in such a position that the slots in each are at the lowestpoint and in a line with each other. This position is always indicated by the pointers 13 13 coming into a position in which they exactly coincide with the vertical pins 1414, respectively. The two slots being in a straight line, the vibrating bar M descends with its prongs one directly over each slot. The vibrating plate 9, carrying the two sliding boxes and heads 12, is placed so that one of the projecting heads 12 is directly under one of the projecting prongs m, the other end of 9, and the head 12 thereto attached, being removed forward in the position so as to be away from the slot to which it corresponds, and leave the slot free for the descent of the prong therein. If a movement is now given to the proper armature-levers, by pressing down the steel attracting-plate, the opposite end will run, and will carry the head 12, to which it is connected, up against the corresponding prong m, and raising it and that end of the lever M up, will force the opposite end down so that thereby the lower prong will project out of the slot of the opposite cylinder slightly-just enough to hold it and prevent the cylinder on that side from rotating. By the same movement the other cylinder is left free to move, it being understood that the object of this swingin g bar M, and its prongs and the slots, is to arrest the motion of one cylinder, and to leave the other free to rotate, as desired. Supposing that it is the cylinder to which the type letters are attached in the order of the alphabet, that is free to move by the operation just described, I connect the current or circuit with the magnets E, and, by means of the pawls and ratchets and side armature-levers above particularly described, the typeletter cylinder, which is free, is made to turn until the letter desired is brought directly over the printing-pad; but the other cylinder is prevented from moving by the prong in the slot. As soon as-the desired letter is over the printing-pad, the current or circuit is disconnected from the magnets E and directed to the magnets D, whereby the printing-pads are lifted, and press the paper ribbon to the letter and print it. The circuit is then again turned upon the magnets E until the next desired letter is reached, which is then printed by the same operation as that described with regard to the printing the first letter. To bring the cylinder which prints the numerals into operation, the armature-lever G, which is under the arrested cylinder, is operated so that the head 12, uponthe sliding box connected with it, and upon the armature-lever now moved, strikes against the prong m and raises it out of the slot, thereby freeing the cylinder, and at the same time arresting the movement of the opposite cylinder, which be.- fore was free.

It is to be observed that the turning of the free or released cylinder always carries round the pointer or pin 13, by rotation of its axle, to which the pointer is secured, and the pin 13 of the moving cylinder, in turning, carries in contact with the arm 10 of the vibrating plate 9, and pressing against the arm, removes the arm out of the way of the slot on its side,

and brings the projecting head of the sliding size of the slots, whereby the vibrating bar M will have greater space to release or relieve free either cylinder, so that the cylinders can be brought to unison or harmony by the magnetic pulsation which is made to pass through magnets E E, operating the released cylinder by the step-by-step movement.

By my improvements in construction of the instrument, the mechanism is greatly simplitied, and many parts used in other instruments are rendered unnecessary, and the expense of constructing greatly reduced, and

the operation facilitated as well as simplified.

Having thus described my invention and improvements, and the construction and op eration thereof, what I claim therein, and for which I desire Letters Patent, is-

1. The combination of the slotted type-cyb inders H H With the vibrating arm or bar M, and its prongs m m, operated so as to arrest or release either cylinder, as desired, so that the one released is rotated by the two sets of magnets E E E E, arranged in the same circuit, all constructed and operating substantially as set forth.

2. The vibrating arm M, the horizontally vibrating plate 9, andthe sliding boxes having heads 12, and operated by the. revolving fingers or pointers 13, combined with the cylinders and armature-levers 0 O, constructed and operating substantially as and for the purposes set forth.

3. The combination of the forked. pawls 1 l, the ratchet-wheel, toothed on opposite sides, the springs or clicks 2, and detents 3 and 4, for regulating the step-bystep motion, substantially as set forth.

4. The square guide-frame 23, and pressure plate or spring 22, for guiding and regulating the paper ribbon, constructed and arranged substantially as set forth.
