.fiPECIPICATION forming part of Letters Patent No. 316,698, dated April 28, 1885.

Application filed August '7, 1884.

To all whom it may concern.-

Be it known that I, HENRY VAN I-IoEvnN- BERGH, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Receiving- Instruments for Printing-Telegraphs, of which the following is a specification.

This invention is designed to provide a receiving-instrument adapted to be 'usedin connection with a printingtelegraph transmitter of a peculiar organization which is described in another application of even date herewith, and this instrument is designed to dispense with type wheels, which are usually employed in printing-telegraph instruments, and

to so organize the parts that it may be operated with great rapidity, and also to avoid the necessity of employing unison devices. The two instruments depend, essentially, in their mode of operation upon each other; but itwill be necessary in this specification to describe the transmittirig-instrument to such an extent only as to show the general plan of transmit- 2 5 ting the various classes of currents required for operating the receiver at the proper times and in the proper quantities. Considering, first, the general organization of the receiving-instrument, the type are carried upon a flexible supporting plate, which is so supported that it is capable of two independent movements, for the purpose of bringing any one of the several type above a printing-platen, across which the paper which is to receive 3 5 the message is carried. These two movements, although independent of each other, may be made simultaneously-that is to say, a resultant movement may be given to the supporting -plate for the purpose of more quickly bringing a type into position to print. The faces of the type are placed in the same plane, and they are arranged in a series of transverse rows. One movement of the fleXible supporting-plate is designed to bring the proper series above the platen, and the other movement, which is at right angles to the first movement, is designed to bring the proper type in that series above the platen, and when both these movements take place simultane- 50 ously the desired type is moved diagonally toward the printingplaten. For the purpose (No model.)

of obtaining these movements, the mechanism which isemployed for obtaining the first movement is actuated by electric impulses of a given strength and of alternating polarity, while the mechanism which produces the sec ond movement-that is to say, the movement in the proper direction for bringing the individual type above the platen-is obtained through the influence of electric currents of increased strength and of either positive or of negative polarity. If, however, it is desired to move the flexible supporting-plate in both directions si1nultaneously-that is to say, in the resultant or diagonal directionthen it will be necessary to transmit alternating impulses of increased strength. The desired type having been brought above the platen, an impression is made by forcing the flexible plate downward at the proper point by means of an electro-magnet, which is vitalized in any convenient manner, preferably, however, through the influence of a prolonged current.

It will be obvious that for the purpose of transmitting the proper impulses i'or opera-t- 'ing this instrument, a transmitter of peculiar organization is required. For this purpose a series of keys corresponding to the type carried upon the flexible plate is supported in a suitable frame, beneath which twoarms are adapted to move at right angles to each other. These arms, when the transmitter is operated, move simultaneously toward the key which is depressed, and each of them is adapted to transmit a number of impulses having the corresponding characteristics, depending upon the distance through which the arms move before they are arrested by the key. These impulses serve to move the plate oi the receiving-instrument a suiflcint distance in the 0 corresponding direction to bring it into position to print the character corresponding to the key which is depressed. The impulses which are thus transmitted during the movement of both arms possess the characteristics 9 5 assigned to each arm, and the plate of the receiving'instrument is thus moved in its diagonal direction.

The invention involves numerous details of construction, which will be described in con- :00 nection with the drawings.

In the accompanying drawings, Figure 1 is tion of the impression-producing devices. Fig.

5 is a transverse section through the'lines 5 5' of Fig. 1, showing the details in the construction of one of the devices for actuating the type-support. details in the construction of the devices employed for returning the type-support to its normal position.v Fig. 8 is adiagram illustrating the general organization of the apparatus, together with the circuit-c0nnections of the same.

Referring to the drawings, H represents'a suitable base, upon which the various parts of the instrument are supported.

* supporting-plate, H, for the type h is carried ing along the teeth of the pinion j wise, if' the pinion j be alone revolved'in the rests upon a similar segment, j

in a suitable frame, H, above the base H. This frame is designed to be moved above a suitable impression platen or roller, H so that any one of the type may be brought into position to print its character upon the paper H, which is moved across the platen in any suitable manner. For this purpose the frame Hi'ssupported by means of a guide or rest, I, and three rack-bars, J, J and J The bars Jfand J rest upon a sector of an'elongated pinion, j, and the bar J 'in like manner The entire plate is thus free to move under the influence of the pinionsj and f. If one pinion, j, alone is'revolved in the direction indicated bythe arrow 00, then the entire plate will be moved inthe' corresponding direction, the bar J 3 slid- Likedirection of the arrow 00*, then the plate will move in the direction at right angles 'to'th'e movement occasioned by the pinion j, and

the bars J and J 2 will slide along the teeth of If, however, both pinions be simultaneously revolved, then a movement will be given to the plate in a resultant or diagonal direction, as indicated by the arrow 00 The type it are arranged'inseries, and

these series are successively brought above the printing-roller H when one pinion alone is revolved, and the individual type in one of the series will be successively brought above the printing-roller when the other pinion alone is'revolved. When both pinions are simultaneously revolved, then the diagonal movement of the plate will cause the first type of the first series to be replaced by the second type of the second series, and that by the third type of the third series, and so on. "If, for example, it is desired to print from the fifth type of the fourth series, a diagonal movement of the plate would be occasioned by the simultaneous movement of bot-h pinions until the fourth type of the fourth series isinpo sition above the printing-roller, and then one 'plied a driving-pawl,

Figs. 6 and 7 illustrate certain pinion alone is revolved for the purpose of bringing the fifth type of that series into position.

For the purpose of obtaining the desired movements of the pinions, a ratchet-wheel, k, is applied to the shaft or arbor of the pinion j, and to this ratchet-wheel there is ap- The pawl It is carried upon the armature-lever 7c of an electromagnet, K. This electro-magnet is included in the circuit of a local battery, 0, the connections of which are. made and broken by means of the armature-lever k of a polarized relay, 70 The relay k is included in the circuit of a main line, L, extending from the transmitting-instrument. One pole of the battery 0 is connected by conductor 10 with a contactstop, is", of the armaturelever k, and this lever is connected by the conductor llthrough the coils of an electro-magnet, K, with the remaining pole of the battery 0. When, therefore, the relay is actuated by means of a curtric impulses of a number dependent upon the v position of the series in which the desired type stands,'and these positive impulses secure the proper advancement of the frame H to bring that series into position to print. It is evident, however, that the type may be the'first, second, or any other type in such seri'es,'and

for the purpose of bringing that particular type above the platen the pinion j,'with its bar, is employed. This pinion is provided with a shaft or arbor, j, carrying a ratchet-wheel, m,which is similar to the ratchet-wheel 70. A pawl, m carried upon an armature lever, m is employed for driving this ratchet -wheel through the influence of an electro-magnet, The electro-magnet K is included in the circuit of a second local battery, 0 the con nections of which are designed to be completed and interrupted by means of an electro magnet, m which is included in the circuit of the main line L. For this purpose the electromagnet m is providedwith an armaturedever,

m, to which there is applied a front contactstop, m One pole of the battery o 'is connected by a conductor, 12, with the stop m ICO ating the electro-magnet k When, however, such currents are transmitted through the main line of whatever polarity, the armature lever m will make contact with the stop an and cause the electro-magnet K to be vitalized. Each impulse, therefore, of sufficient strength will cause the pawl m and ratehet-wheel m to advance the frame H in the corresponding directionthrough the distance corresponding to that which separates one type from a second type in the same series. If these currents be of negative polarity, then the eleetro-magnet K will not be vitalized, and the frame H will be driven only by the pinion j If, however, they be of positive polarity, then both pinions will be actuated simultaneously, and the resultant movement will be given to the plate in the direction of the arrow or. Any one of the several type may thus be brought into position to print by the transmission of the proper electric impulses, and-for the sake of economy of time more or less of these impulses may be simultaneous that is to say, a simultaneous movement of the two pinions may be obtained by the use of positive currents of sufficient strength to actuate the electro-magnetm. In

of any type which has thus been placed in position to print, an electromagnet, P, is employed. This electro-magnet is designed to be vitalized by means of a local battery, 0", the connections of which are controlled by means of the armature-levers of the electromagnets K and K and an armature-lever, n, of an electro-magnet, M, which is included in the main line L. For this purpose one pole of the battery 0" is connected, bymeans of a conductor, 14, With an insulated contact-point, it, carried upon the armature-lever It, and this contact-point is-provided with an insulated resting-point, a The point a is connected by conductor 15 through the coils of the electro-magnet 1? with the armature-lever a. This lever is provided with a front contactstop, of, which in turn is connected through conductors 16 and 17 with an insulated contact-point, n, carried upon the armature-lever m A resting contaotstop, 11F, applied to this .point, is connected by a conductor, 18, with therefore, both armature-levers k and m are remote from their electro-magnets, and the armature-lever n is drawn forward then the current of less strength than is necessary to vitalize the electro-magneta and of negative polarity, and also of greater duration than is normally required for actuating the two electro-magnets, k and a. Vhen the electromagnet P is vitalized,its armaturedever p is thrust downward toward the face of the plate H, and the extremity p of this lever serves to strike the particular type which chances to be above the printing-platen. The plate H is sufiiciently flexible to allow the downward thrust of the lever p to strike the face of the type against the surface of the paper carried upon the printingroller H, and to thus effect an impression.

It remains now to describe the means whereby the plate is returned to its normal position after an impression has been effected. Two retaining pawls or dogs, r and W, are respectively applied to the ratchet-wheels It and on. These pawls constitute extensions of the armature-levers of two electro-magnets, It and R respectively. The electro-magnets It and R are included in the circuit of a local battery, 0; but the connections of this battery are designed to be completed only for such brief periods during the operation of bringing a type into position to print that the electromagnets will not become vitalized. NVhen, however, an impression has been made and it is desired to return the type-plate to its normal position, the electro magnets R and R are allowed to become vitalized. For this purpose one pole of the battery 0 is connected by conductor 19. including the coils of the electro-magnets R and R with the armature-lever n. The back contact-stop,r of this armaturelever is connected by means of a conductor, 20, with the remaining pole of the battery 0. \Vhen, therefore, the electro-magnet n is not vitalizcd, the circuit of the battery 0 is completed, and the pawls r and r are drawn away from or out of engagement with the corresponding ratchet-wheels. During the transmission, however, of alternating impulses, or of the successive impulses employed for moving the typeplate, the armature-lever n continues to vibrate between the stops r and n with such rapidity that the circuit of the battery 0 is not completed sufiicient time to vitalize the electro-magnets R and R; but when the current of the main line is interrupted, then the continued contact of the armature-lever with the stop 1' serves to cause these electro-magnets to be vitalized.

To the shaltsj and j, respectively, there are applied two coiled springs, s and 8 These springs are caused to be wound by the forward movement of the corresponding pinions, and when the wheels are released they serve to return the pinions to their normal or starting positions. The dogs 1" and 1", however, prevent this return during the operation of setting the plate in position to print. WVhen,

however, both armature-levers and m are remote from their electro-magnets and the electro-magnets Bi and R are vitalized, and the pawls r and r are respectively drawn out of engagement with their ratchet-wheels k and m, then the springs s and s serve to rotate the pinions back to their starting-point, thus placing the type-plate in the position shown in the drawings.

Suitable stops, it and are applied to the pinions j and j, respectively, for the purpose of limiting the backward movement of immediately follows may be employed for printing.
