SPECIFICATION forming part of Letters Patent No. 580,617, dated April 13, 1897.

Application filed MaTOll 6, 1896.

Serial No. 582,024:- (No model.)

To all whom it may concern.-

Be it known that I, HERMAN KREUSLER, a resident of Kreischerville, Richmond county, State of New York, have invented a certain new and Improved Printing-Telegraph, of which the following is a specification.

My invention relates to printing-telegraphs, and more especially to that class of telegraphs wherein the marking or printing is done by means of an instrument actuated or moving synchronously with a transmitting instrument.

My invention consists in the construction hereinafter set forth and claimed.

My invention will be understood by referring to the accompanying drawings, in whichi Figure l is a general diagrammatic view of apparatus embodying my invention, showing the circuit connections in detail. Fig. 2 is a detail diagrammatic plan View of a transmitting apparatus embodying my invention. Fig. 3 is a detail diagrammatic plan view of a receiving apparatus embodying my invention and corresponding to and capable of operation in conjunction with the transmitter shown in Fig. 2. Fig. 4 is a detail side elevation of the transmitter, showing also the circuit connections. Fig. 5 is an enlarged detail view of the rear end of one of the keys of the transmitter-keyboard. Fig. 6 is an enlarged detail View showing a pair of the cooperating contacts of the receiver, the same forming the circuit-closer of the top levermagnets.

Stated generally, the apparatus illustrated consists of a transmitter comprising a keyboard and a transmitting-arm, which transmitting-arm controls the line-circuit, in which is placed a receiver havinga similar traveling arm which controls the local circuit of a suitable type-writer or mechanical-writing machine. These transmitters and receivers may be placed upon the line in various numbers and variously arranged, but the preferable mode of connecting and arranging them is shown in Fig. 1.

Before proceeding to describe the general system I will now describe the transmitter and the receiver separately and will then describe their connections and conjoint action."

Referring particularly to Figs. 2, 4, and 5,.

a contact-arc G, also mounted upon the baseboard. Series of keys H are pivotally mounted in proximity to the contact-arc G, the said keys being shown as pivoted to a curved rod I, mounted in brackets d, rising from the baseboard and cooperating with a contact-plate J, above which they are suspended. The keys converge and their inner ends are adapted to arrest the arm F as it moves. Referring now to Fig. 5, which shows the rear end of one of these key-levers H, we note that the rear end is provided with an upturned tang e, which tang is shown as inclined at its top and provided with a notch f. These, keys,which are shown as converging toward the contact-arc G, have their rear ends in such close proximity thereto and to the path of travel of the end of the arm F as to cooperate with the end of the swinging arm F, as will more fully hereinafter appear. Magnets K are mounted upon the base-board beneath the pivoted armature E and serve to swing the said armature and its horizontally-swinging contact-arm up and down, the said armature being connected with the said arm by a pivotal connection and also by means of a restoring-spring g. The driving means for the worm-shaft O is constituted by a spring-motor L, which is provided with a control-wheel M, governed by a pivoted detent N, to which an armature O is fastened, magnets P upon the base-board serving to control the said armature. In lieu of the spring-motor and detent apparatus other driving means may be used. The magnet P, as

well as the magnet K, is in the present instance controlled by a local circuit manipulated through the keyboard. This local circuit is shown as consisting of a wire 1, which connects with the said magnet and with the rod I, which is in common electrical connection with the keys H, each of which forms during the normal state of a transmitter one pole of the local circuit, the other pole being constituted by the contact-plate J, from which the 'wire 2 leads to the magnet K, the said magnet K being connected to the battery 4 by a wire 3, the opposite pole of the battery being connected by a wire 5 with the magnet P, so that when a key is depressed we have a circuit from the battery by wire 5, magnet P, wire 1, rod I, key I-I, plate J, wire 2, magnet K, and wire 3 back to the battery. The effect of the passage of the current will be to release the detent N from the control-wheel M and swinging the armature E downwardly. The effect of releasing the control-wheel will be to start up the motor K, which, driving theworm-shaft C, will swin the rod F (whose bowl has been entered into the groove of the shaft by the swing of the armature E) in the direction of the arrow.

The receiving end of the circuit is shown in Fig. 3, to which reference is now invited. In this'figure, Q is a motorhaving a control-wheel R, which is controlled by a detent carried upon a pivoted armature h-under the influence of a magnet S. This motorserves-to drive a worm-shaft T, which is locatedin proximity to a receiving-table of contacts shown as aseries of insulated contact points c' 'i i 2' t, &c. Pivotedv upon a verticallyswinging armature U, which is controlled by a magnet V, is an arm W. This arm is pivoted to swing in a horizontal plane and is connected with a restorin g-sprin g j,-Whi 3h serves to restore it to its initial position, and is also provided with a bowl- 7c,which enters the groove tin the worm-shaft. This arm is adapted for cooperation with the contact-points 1 2 1 ;-&c., before referred-to. and is swung along the path formed by the said contact points when the motor Q is operated. The

' magnets S and V are in the line-circuitand are actuated by the same impulse, the magnet S operating to release the detent h from the control-wheel R, whereupon the motor starts up, and the magnet V- operating to swing the armature U- and arm WV downward to enter the bowl 7t into the groove 25 in the worm-shaft T, so thatas soon as the-circuit of the magnets Sand V is closed the arm W will be swung upon its vertical pivot. This arm will not, however, contact with thecontact-points 71,850., until the circuit of the-magnets S and V is broken, for the arm travels below the contact-points, as 'will be seen in the detail side View, Fig. 6. As soon, however, as the circuit of the magnets S and V is broken the motor will ceaseto operate and the armature U will swing upward, carrying thearm into contact with one of the contactpoints, thereby touching the contact-point which the arm. maybe opposite at the moment of the breaking of the circuit, the-said arm being of such a length as to just touch the contact-point as it rises past the-same.

The arm is raised by the restoring-springl above the level of the contact-points and is guided in its upward movement by the bowl working against the edge of the groove in the worm-shaft, the said bowl being of such length as to remain in contact with the groove until the arm has touched and has been raised above thelevel of the contact-point which it may be opposite, when the bowl passes out of the groove and the spring] is permitted to swing the arm back to its initial position.

The said swing takes place above the level of the contact-points and out of contact therewith by reason of the fact that the bowl does not-leave the groove until the end of the arm -ula-tions of this writing-machine! may be effectedbyregulating the stoppage of thearm W, which is the receiving-arm, in front ofany predetermined contact-point.

Referring now to Fig. 1, we have thegeneral arrangement of circuits and .apparatus. In this figure it will be noted that the linewire A is connected to the wire 13,. which connects with the-magnet S, -which :magnet S is connected-withthe magnet V bywi-re 14,

the magnet V being connected to; the linewire A :in which the battery A is interpolated and which is-connected to the contact strip or rail G- of the transmitter,- theilinewire A being connected to the armatureE of the magnetK, so that as soon as the mag- .net K- is operated to bring =the-arm=F into contactwiththe contact-rail G? thecircuit will be closed through the magnets-S and V. As before mentioned, the closing'of the circuits through these magnets will have the effect of starting up themotorand-driving the arm TV through the medium of r the wormshaft 'T. As longas the circuit is closed, which will be-as long as the arm F contacts with its rail, the arm W will continuetomove, and the motors L and Q being synchronous motors the arms will be driven atthesame rate of speed-and-will= consequently, in the apparatus shown, traverseequal' spaces.

- It-will' be observed, therefore, that 'by controlling the extent of the horizontal. swing-of the arm F- the-extent of swing-ofthearnrW may be very exactly controlled, so as to 'produce the desiredeffects upon thewriting-machine Y, which effects may,'as beforestated, be of various-kinds, the magnets being connected, as before pointed out,to the-separate insulated contact-points z','i,'t' &c.,-and being. provided-with a common return 15, which is electrically connected with the armW, so that thearmNV will close the circuitof-any magnet by touching the contact to which the said magnet is connected. The keys of the keyboard regulate the distance of travel of the arm F-that is to say, by depressing a key a local circuit is closed, by which the arm is engaged with its propelling worm-shaft and carried along thereby, the arm W following the movements ofthe arm F until the end of the arm F comes in contact with the tang e of the key H, when it will ride up the incline thereof and be thereby elevated from contact with the arc G, breaking the controlled circuit of the arm W and bringing the said arm to rest, the notch f engaging the arm to prevent a retrogression thereof until the key H is released, whereupon the restoring-springs g and a will restore the arm F to its initial position, the arm WV being restored by its restoring-springsj and Z. These manipulations may be repeated as'often as desired.
