ADOLPHUS A. KuUDsoN, or BROOKLYN, NEW YORK, Assienon To THE GOLD ANDSTOOK TELEGRAPH COMPANY, OF NEW YORK CITY.
IMPROVEM ENT IN PRlNTlN G -TELEGRAPHS'.
Specification forming part of Letters PatentNo. 133,4 2, dated October. 17, 1876; application filed February 1, 1876. 3
To all whom it may concern;-
Be it known that I, ADQLPHUS A. KNUD.- SON, of the city of Brooklyn, county of-Kings,
and State of New York, have invented certain.
new and useful Improvements :in Printing.- Telegraphs, of which the following. is a full and exact description, reference being. had. to the accompanying drawings. V
Figure l is a plan of theapparatus from the top. Fig. 2 is a side elevation, with a sea This invention pertains .to the class of print ing-telegraphs which have the type-wheels driven by a train of gearing and a weight or spring, or some other motor, and in which the type-wheels of the several instruments in the circuit must be brought intothe same position at rest, or what is termed unison with each other and with. the transmitter; and. this in.-
vention consistsof a novel combination and.
arrangement of parts, which will be. fully hereinafter described, and specifically pointed out. in the claims, a preliminary description being deemed unnecessary.
At A is represented the base of theapparatoe, on the under side of which are supported the electro-magnetsfione pair in a vertical position, as at B, for operating the printing .or press lever, and two pairs in a horizontal position, as at G and O, for operating the type-v wheel. Between these last two pairs of magnets is mounted a polarized armature, as at D, to which is attached an escapementflever, as at E, which extends up throughthebaseA, and is forked at its upper end, and provided with pallets to engage with an .escapementt wheel, as at F, on the type-wheel shaft G, the type-wheel being shown at G. These several magnets are all connected with the main circuit, and the several parts thus mentioned are well known, and are embraced in a previous patent to me.
The drivingrtrain or motor, alsoshown at H, where the main stem for winding up the pallets and the escapement wheel, so that. said lever can vibrate. to and from the plane' of said wheel when desired. Now, it is manifest that if the motor-train be in action upon the type-wheel shaft, and the pallets be drawn out of contact with the teeth of the escapement-wheel, the type-wheel will begin to run instantly and freely, and continue until the motor is checked.. A stop is therefore, attached upon the side of the escapement-wheel, as at F, or it may be placed on the shaft G, but is so arranged relatively to the teeth of the escapement-wheelthat when tlie pallets are disengaged therefrom said stop will, in less than one revolution of the escapement-wheel, come in contact with the end of the pallet; lever, and thereby stop. the rotation of the type-wheel. pallets from the escapement-wheel in the pres ent case is by the use of a small electro-magg net, asat K, between the poles of which the pallet-lever is placed, and on the opposite side is the armature, as at K fastened'upon'a lever,.K (see Fig. 4,) the free. end of which rests against the side of the pallet-lever, and in such a position as that when the armature K is attracted to the magnet K the pallets. will be forced out of contact with the escape;
ment-wheel, audit will be permitted to run freely and quickly until the stop F strikes the end of the pallet-lever or some projection thereon. This operation is accomplished automatically by the use of a small local batg tery,.the wiresto which are shown at L L,
one .of which is attached to a bracket, as at L on the. top of the base, where, through a vibrating tongue, as at L its connection is. made to an insulated brake, as at L, one end The method of disengaging the of which brake is arranged to come in contact with a pin, L on the type-wheel shaft. The other wire, L, from the battery is connected directly to the magnet K.
Said vibrating tongue L is simply a piece of brass fastened upon the top of the base, and is not an armature, but is provided with a facing of soft iron at one or more points on its under side, to come in contact with projecting poles from the press-magnet, as at L (see Figs. 6 and 7,) and by which the tongue is drawn down toward the press-magnet, (whenever the main circuit is working,) and out of contact with the regulating-screw L, which is mounted in the bracket L and to whichone of the wires, as already stated, is attached; consequently, when the said tongue is held upon the press-magnet or the projections therefrom, the circuit between the local battery and the magnet K, for disconnecting the pallets, is broken, and therefore the pallets are held in working position by the spring at M under the base A. (See Fig. 4.) When, however, the main circuit is broken, andthe press-magnet ceases to hold the vibrating tongue L down, then it rises in contact with the regulating-screw L and closes the local circuit, and thereby instantly draws the pal-- lets out of contact with the escapement-Wheel on the type-wheel shaft, and the type-wheel.
instantly begins to revolve freely and quickly, being driven by the motor-train. But in less than one revolution the stop on the escapement-wheel comes in contact with the end of the pallet-lever, and the type-wheel stops. At this instant the pin on the type-wheel shaft strikes the end of the brake-piece at L, which scribed, or it may be operated by any other magnet in the main line.
It is evident that the armature acted on by the magnetK, and controlling through the medium of lever K the relation of the escapement-lever and escape-wheel, may be placed directly on the escapement-lever, as shown in Fig. 8,in which case the magnet K may, if desired, be a singlespool magnet.
Another improvement in this apparatus" consists in the combination of certain devices with the type-wheel shaft, by which a bell may be struck from the sending-station upon each one of the instruments in the circuit, in order to call attention in the change of the reports, or to strike the time of day, if desired. This is accomplished by mounting a bell, as
as at N, in the type-wheel shaft, and which is caused to vibrate backward from the shaft whenever the pin strikes said beveled end. In the inner side of said pendent arm there is a pin, as at N", which extends through the frame and in front of the pendent stud N so as to press said stud back over the press-lever, and hold it there when desired. Now, at the proper time tosound the bell, the type-wheel or its shaft is revolved, to bring the pin N on the shaft against the pendent arm N and thereby press back the pendent stud N on its lower end directly over the lever of the pressmagnet, and therehold it until the press-lever can be operated as manytimes as it is desired to strike the bell.' When finished, the instrument may return to unison again, as already described, and by the same mechanism;
Having thus fully described my invention, I desire to, and do, claim- 1. In a printing-telegraph, the combination, with the motor-driven train,a type-wheel, and an escape-wheel, both rigidly secured to a shaft, of a pallet or escapement lover of an electromagnetic escapement, and an electromagnet operating to disengage the leverfrom the escape-wheel, and'allow both the type and escape wheels to be turned freely and instantly to a designated point by the driving-train,
substantially as described. l
2. Thecombination, with the escapementlever, of a magnet and a local circuit therefor,"
controlled by the main circuit, and'operating to disengage the escapement or pallet lever," and rigidly-attached escape and type wheels,
substantially as described;
3. The combination, with the pallet ores capement lever, of two electro-magnets, one
controlling the action of the lever upon the escape-wheel, and the otherits positionlin relationthereto, substantially as described.
4. The combination, with the pallet orescapement lever, arranged to engage with or be disconnected from an escape-wheel, of a stop on the type-wheel, or shaft thereof, arranged to take against the pallet when the same is disengaged, and simultaneously stop the type and escape wheels at the desired point, substantially as described.
5. The combination, ina printing-telegraph, of a circuit-breaker with the type-wheel, or its shaft, and an electro-magnet, whereby the escapement mechanismmay instantly and auto matically return to its working position, substautially as described. p 6. The combination of the electro-magnet 0n the outside K, its armature and lever, and a local circuit,
