PRINTING-TELEGRAPH.
SPECIFICATION forming part of Letters Patent No. 274,300, dated March 20, 1883,
Application filed February 23, 1883.
To all whom it may concern Be itknown that I, STEPHEN D. FIELD, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Piinting-Telegraphs; and I do hereby declare that the following is a full and exact description of the same, referenoebeinghad to the accompanying drawings,
and to the letters ofreference marked thereon.
My invention relates to that class of stepby-step or gold and stock printing-telegraphs in which two type-wheels are used, from which a record is made on one fillet or band of paper in two parallel lines; and its object is to furnish a novel, simple, and reliable means for determining at will which one of the two type-wheels shall be printed from. The general construction of the apparatus is the same as that shown and describedin my prior application filed December 7, 1882, and bearin g Serial No. 79,185., Each type wheel is supported on its own shaft, which carries an escape-wheel controlled by an anchor. Both anchors are upon the same shaft, controlled by the armature of one polarized electro-magnet in the main type-wheel circuit. A motor is provided, tending normally to rotate continuously both type-wheels, which tendency to continuous rotary motion is regulated and changed by the anchor and escapement noted into a step by -step or intermittent rotary motion. as in the application noted, the dili'erence being in the means employed for determining which wheel shall be printed from, while the other is held in such position that no impression therefrom is bad. Each wheel is provided with a blank or unison point, where, if the paper be impressed thereat, no record is made.
An organization is provided to always hold one of the wheels at that point, while the other is allowed to rotate and be positioned for printing. In the type-wheel circuit is placed an ordinary or neutral electromagnet with an ordinary armature, armaturelever, and retractor. The armature-lever at its free end is connected to a bar at a right angle. In openings in this bar take the ends of uprights, having lugsor projections upon their inner sides in such position that the lever of the printingmagnet shall always, when called into action, strike upon one or the other, and carry up with Thus far the construction is the same (No model.)
i it the corresponding upright. The uprights at their upper ends are pivoted to the ends of a rocking bar, hung at its center, a T-arm projecting downwardly, the result being .that if an upright be forced upwardly the T-arni is carried to that side. The free or moving extremity of the T-arm carries two stops, one on each side. positioned to come in contact with stops on the type-wheels, one on each wheel, sothat by moving an upright a stop on the T-arm is carried into the path of the stop on one wheel and removed from the path of that on the other.- This may be more clearly understood from the following detailed description, and from the drawings, in which Figure 1 is a perspective of the parts embodying the invention, and Fig. 2 is a front view of the extra magnet and attachments for determining which wheel shall be rotated and positioned for printing.
The framing, pa per-feed, inkingdevices, motive power, 850., forming no part of this invention, and being well known to those skilled in the art, are omitted from the drawings, inorder that the real matters of invention may be more clearlyshown, it being well understood that in practice they will. be supplied in any of the well-known and usual ways.
-A A is a polarized electro-magnet in the type-wheel circuit 1 1, and having an armature, a, attached to a vibrating or rocking shaft, B, carrying anchors b b.
D E are two type-wheels, each having its own set of characters, its own shaft, and escape-wheel, D being on the shaft (J with escape-wheel ti, and E on shaft 0 with escape- In the printing-circuit 2 2 is the printing or 1 press magnet P, having armature p, retraotor f, and armature-lever P L, carrying the platen or press P, of sufficient size to take upon either wheel D or E. The printing-lever P L is enlarged at t i, or provided with projections.
the lever J is connected to an arm, H, ar

ranged to slide in any well known and suitable manner. In apertures in H, at a distance apart slightly greater than the distance apart of the outer edges of D and E, take the free ends of two uprights, F F, having lugs or projections f f upon their inner edges and just above the parts iiofP L. At their upper ends F F are pivoted to a cross-arm, G, hun g at its center upon an arm, 9, suitably supported in or from the framing of the instrument. From the center of G and below y depends an arm, T, having lugs t on each side.
Upon each type-wheel is a blank or unison point, and each wheel has also a. stop or lug, 0, adapted to contact with 1. when the wheel is in such position that the blank or unison point is presented to the press or platen P.
' The parts H, F, F, T, and t are so adjusted that t must always contact with the lug 0 on one of the wheels and stop it against the stress of the motor thereon.
The transmitter is so arranged that when stopped to position one wheel. it shall hold the circuit 1 1 closed, while when stopped to position the other wheel it shall hold the circuit l lopen. Supposing, now,that the wheel E has been in use, has been positioned and printed from, during such operation the stop t has contacted with 0 on D, held D against rotation and in such position that the blank space was opposite P, so that no impression could be made therefrom. A change to D is now to be made. The transmitter is turned to bring E to blank and stopped with the circuit l 1 closed. The force then of I holds J to itself, and the parts are in the position shown in Fig. 2. The printing-circuit 2 2 is now closed and the armature-lever P L thrown up, its projection i striking F, lifting it and turning G on its center g, so as to swing t on' T clear ofo on D, and put it in the path of 0 on E. The transmitter being then used, D is free to rotate, be positioned, and printed from" so long as desired. When desired to change to E again, the circuitl 1 is left open wit-h the wheels brought to blank and the circuit 2 2 actuated, when t strikesfon F, lifting it, depressing F and causing t to be swung into the path of 0 on D. By these means one or the other of the two type-wheels and its escapement is certainly and readily locked at will against the stress of the motive power, and in position to give no impression, while the other is allowed to be freely rotated by the motive power, as controlled by the cscapem'ent, and be positioned and printed from.
What I claim herein, and desire to secure by Letters Patent, is?- 1. The combination, in a printing-telegraph, of two type-wheels, a polarized magnet controlling the esoapements of both, a neutral magnet in the escapements-circuit, and means, as described,controlled by the neutral magnet for locking one of the wheels, substantially as set forth. y
2. The combination,in a printing-telegraph, of two type-wheels, a polarized magnet controlling the escapements of both, a neutral magnet in the escapement-circuit, and means controlled thereby adapted to determine which wheel shall be printed from, substantially as set forth.
' 3. In a printing-telegraph having two typewheels, each provided with its escapement, the combination of the two type-wheels, a neutral magnet, and a locking device controlled thereby, locking one wheel and its escapement and unlocking the other, substantially as set forth.
4. In a printing-telegraph having two type wheels, the combination of a polarized electromagnet controlling the escapements of the typewheels, a printing-magnet, a neutral magnet, and means controlled thereby'for determining which wheel shall be printed from, substantially as set forth;
5. In a printing-telegraph having two typewheels,thecombination of a polarized eleotromagnetcontrollingtheescapementsofthe typewheels, a neutralmagnet in the same circuit determinin g the position of the lockin g devices,
and a printing-magnet having anarmature-lever adapted also to move the lockin g devices, substantially as set forth.
6. In a printing-telegraph having two typewheels, a locking device for holding one typewheel stationary, consisting of a rocking lever having a stop attached thereto, and pivoted to two arms moved by alever attached to an independent neutral magnet, so that the movement of the arms controls the position of the stop, substantially as set forth.
This specification signed and witnessed this 19th day of February, 1883.
