Since thisA relay vhas very little. mechanical work jto do it may be very sensitive and easily eration of the printer on .-much lon er lines t-lian Athe ordinary stock ticker can e operated o'n successfully,l also a number of Such separator relays, corresponding` to separate printers,.ma 'be included inthe saine circuit operated. may 'be increase, I commonly place this .separator relay, Yor Vthe separator relay cfa-,plurality oflpiinters when animiber qfprinters are to be worked -:trom the samecircuinin u local circuit controlledby a line relay; and for the same reason I com-v ,9.0, operated, and for this reason permits theopmachine is particularly adapted for receivprinter; in the general arrangement of the ,I will now proceed to describe my invention with reference to the accompanying 4on the line 6-6 of Fig. Q, this view showing monly place the magnet of the escapement l mechanism,controlling the rotation of' the type wheel, in a local circuit also, both of these local circuits being controlled by the Sallie line relay. By reason of the use of this line relay, separator relay, and the local circuits and conmiutator mentioned, I require only one strength of current in the line circuit and only one class of signals therein, namely, current alternations; and the-se alternations may be of quite'higlffrequency, comparable to the alternations produced by a VVheatstone transmitter operating at high speed. ln fact, since the line conditions controlling the operation of my printer are much the same as those which obtain in lVheatstone operation, the printer is susceptible of being ope `ated over lines of very great length.

My` invention consists in .means whereby the complete control of the various meel-1anisms of the printer is effected with only one class ofA line signals; in the separator relay controlling the hannner magnet and the magnets of various other mechanisms of the mechanisms of the machine, whereby the ing Hat sheets of considerable length and. Width and for printing in successive lilies, z'. e., for page printing, all in full view ot the operator, and in various other features of construction and arrangement of the parts, as hereinafter described and particularly pointed out in the claims.

The objects of my invention .are to improve and simplify the printers of printing telegraph systems, to avoid the use of more than one line conductor and more than one class of signals in that line, to adapt the printer for high speed operation over relatively long lines, to make the printer sensitive and accurate, simple, compact, durable, relatively inexpensive, and easily kept in repair, and to particularly adapt the printer for use for receiving ordinary telegraph messagesl on. ordinary telegraph message blanks, and for operation under the charge of ordinary receiving operators drawings, in which one form of printercmbod-ving the said invention is illustrated, and Will 'then point out the novel 'features in claims.

In said drawi1'1gs2--lt`igure1 .shows a front elevation of the machine; Fig. 2 an elevation of the right hand side of the machine; Fig. 3 an elevation ofA the ,left hand side of the t machine; Fig. 4 a top view of the machine; Fig.' v5 a longitudinal vertical section of they machine looking from the right hand side; Fig. 6 a transverse sectional elevation taken particularly the escapement magnets, the

In the drawings numerals 1 and 2 designate respectively a base plate and a top plate, 3-3 designate pillars between these plates l and2, and 4--4 designate legs, usually of rubber or like material, on which the machine stands.

5--5 designate side guide rods of a paper carriage, G-G designate end plates of such carriage connecting said-rods, 7 designates a feed roll mounted in said carriage and 8 5 designate idler rollers mounted upon a shaft 9 and adapted to hold paper against the feed roll 7, said shaft heilig mounted to slide up and down somewhat in guides IO of the end plates 6 of the earriage,ia1nl being normally held downward by s]1)1'ings 11. I

12-12 are handles by which the feed roll may be rotated. p

This machine has no real platen, butA the carriage has a iiexible strip il, (usually oi rubber); and the paper to be printed ou is held in the carriage above said strip. A hammer hereinafter mentimied, located below the flexible strip, is arranged to drive the paper so held against the type faccson the type wheel hereinafter mentioned. la per guide plates V1:3 and l() are provided in iront of this strip llt and-in rear otl the ieed roll T, as shown particularly in Fig. 5. In feeding paper into the machine, thev paper sheet is laid upon the guide plate 15 and thence passed between the strip let and the lypewvheel, and between feed roll 7 and idler rolls 8, and thence over the guide plate 16.

Numeral 1T designates grooved guide rolls mounted upon the top plate of the machine,

as guides for the guide rods 5 oi" the carriage.

bove the strip ll there is a type wheel 1S mounted upon a shaft-'19; said typciwheel having a hub-bushing Q0 slotted as shown particularly in Figs. 2 and 5, a key 21' mounted on shaft 1t) working in this slot; the construction being such that'while the bring one oranother of itsjrowsof characon the' vsha-ft of fthe motel.'

ters into printing position.

Printing is e'ectedfby a hammer 2x2-forming tl 1e g plunger of a solenoid 23, said; harnmer being located ,directly beneath the type lwheel 18 and the strip 14 and being arranged to be driven upward, when the solenoid is'energlzed.

24, Figs. 2, 3 and v4,?designates a motor by means of which the type wheel shaft -19 and the carriage-feeding shaft are driven.- v Shaft 19 is driven -from this motor by means of a belt 'V passing-about a suitable pulley 26 and about' a 'suitable Apulley 27 yon the' shaf 19, "this latter pulle not bein keyeddirectly to-shaft19 but riving sai shaft throughthe friction driving device shown in detail in Fig. 10, and comprising friction disks 28. pressed against the web of said pulley 27 by a spring 29, there being rubbing pieces of Ifelt, leather, or other suitable material, 30, be-

tween thedisks' 28 andthe web of said pul.

ley 27. This friction driving device permits continuous operation of the motor 24 and pulley-27, while shaft 19 will be driven by said pulley or will be Vheld stationary, ac-

-cording'as .the escapement mechanism for said shaft perm-its. `'T his escapement mechanism, shown particularly-in Figs. 5 and 7, comprises an escapement wheel 31, secured to shaft 19, and an escapement anchor 32 mounted Ona-n arm 33, secured to a pivot shaft 34, to which is also secured the armature 35 of field magnets 36. 4The armature 35'is polarized by a magnet 37, the pole pieces 38 of which are extended to embrace the hub of the armature 35,.as clearly shown in'Figs. 6 and 7. It willlbe clear that current reversals such as are commonly employed to operate synchronous printers, occurrinor in the' circuit of the field magnets 36, will cause the escapement anchor 32jto be vibrated'back and forth, permitting shaft 19 tobe rotated step by step by motor 24.

In synchronous printers of the step by step type, synchronizing means are commonly. provided to bring the transmitter and printer into synchronism; and such synchromzing means are provided in this machine.

comprising a smral'thread 39 on shaft 19, and a pivoted stop arm 40 adapted to ride in this thread and tobe moved thereby toward the left of Fig. 2 and provided With 'a'lug 41 adapted to engage a projection 42 when said arm`40 has been carried as far to the left as it can go, engagement of the lug 41 and stop projection 42 arresting rotation of shafty 19. The synchronizing der vice further comprises a lifter 43jfor arml y 40, mounted upon a shaft 44-arranged to be oscillated by the armature 45 o f a magnet I ing device, illustrated in etailin Fig; 12,. 46, each time the solenoid 23 or one of the landicomprising disks 67 pressed against the 130 f said latch being the armature' o other magnets hereinafter mentioned operi ates, andwhen vsaid lifter 443 is operated. it raises the arm 40 out of the splral thread on shaft 19, permittin said arm to be pulled back to the right o Fig. 2 by a spring 47;A

the construction 'being such that so long as,y

characters are being steadily printed the stop arm 40 will not be permitted to move" far enough tothe left of Fig. 2 to arrest the rotation of the shaft; but when the type Wheel of the printer is caused to rotate a number oft-imes withoutvthe printingof a character, the lug 41 vof stop arm 40 is brought into engagement with the stop prochronizing'device is in principle the same i as the synchronizing devlce commonlyused on stock tickers and the like, and, therefore, l

more detailed description of its operation 'is not required. 4

As shown, the type wheel 18 has t'wo rows of type faces; and one row or the other is brought over the hammer 22 by moving said type wheel along the shaft 19. For this pur-f pose said type wheel is embraced by a slid-l ing yoke 48 Fig. 2) mounted upon a sliding rod 49, itsel arranged to be operated by -a sprin 50 andby a bell crank 51 connected i by a4 ink 52 to the armature 53 of a shift ma net 54. To hold the type wheelin its shi ted position. against the` act-ion of the,-

spring 50, a'latch 55 (Fig. 6) is, rovided,` a latch magnet 56. The spring 57 of this latch 55 is a compression spring tending to move the latch away from the magnet and into en#- gagement with the armature 53.

Upon the left hand side of the machine,

as viewedifrom'the front, there is a shaft 58vv carrying a gear 59 (Fig. 3) meshing with i the rack bar 60 of the paper carriage of the machine. This gear 59 is driven from shaft 58 by mea/ns of a counter shaft 61 (Figs. 2 and 4) driven by gearing from the shaft of the motor and provided with a beveled pin ion 62 (Fig. 4) adapted to engage one or the other of two beveled gears 63 and 64 keyed to the shaft 58, but arranged to be moved axially thereon, to bring one or the other of .said gears into engagement' with the pinion- 62, by thearmature lever 65 of a carriage return magnet 66. It is clear that the effect of shifting gears 63 and 64 is to 'change the direct-ion of rotation `of shaft 58. Gear.59 is driven from shaft 58 throu h a friction driv- -roll 7.

vrodY 8() to the left of Fig.

sides 'of saidgear 59 by a spring 68, there being suitable rubbing pieces ($9 between these disks G7 and the faces of the gear. Normally shaft 58 rotates in such direction as to cause gear 59 to tend to feed. the carriage toward the left (looking from the front of the machine) but such motion of the earriage is controlled by an ordinary typewriter escapenient mechanism comprising an escapement.wheel,70, an escapement anchor to the rack bar 60 of the carriage by means of a pinion mounted on the same shaft as said escapement wheel 70 and intermeshing with said rack bar.

To permit return of the carriage not-Withstanding engagement of the escapement wheel 70 by the escapement anchor, said es rapement wheel is driven from pinion 76 through pawls on said escapement wheel, engaging teeth of a ratchet wheel driven by said pinion, as indicated in dotted lines in Fig. 8. This is a well known construction.

For feeding the paper lineby line in the carriage, I provide a feed magnet 77, the armature 78 of which actuates a pusher 79 in such 'manner that'when the said magnet T7 is energized the front end of 'this pusher pushes against a rod 80 extending lengthwise of the carriage and mounted upontwo levers 81 atopposite sides of the carriage, oneof these levers carrying a pawl 82`which is adapted to engage teeth of a ratchet wheel 83, mounted on the shaft of It will be clear that each time feed magnet. 77 is energized pusher 79 will move 11, causing the ratchet lwheel 83 to be moved forward one tooth; and that as soon as the magnet is deencrgized the pusher 79 .will retire, permitting springs S4 to move. back arms S1 and the pawl 82, so that said pawl may engage another tooth of the ratchet.

'lhe circuits of the shift magnet 54, tht` latch magnet 5G,`the carriage return magnet 06 and the paper feed magnet 77, are controlled by a commutator 85, mounted upon the type wheel shaft .19 to rotate. in synchronismfwith the type wheel, and by a `series of brushes 80, S8, 89, 90 and 91, mounted upon a block of insulation S7 and adapted to engage Suitable conductive strips of this commutator.

Fig. 13 shows diagrammatically circuits of the apparatus, also diagrammatically a transmitter such as is commonly used in synchronous printing telegraph systems. In said figure the transmitter there diagrammatically illustrated comprises a shaft92 arranged to be driven bysome suitable friction driving the paper feed detail.

device, in this-'case illustrated as a belt wheel rent reverslng commutator 95 of well known type, and driving the trailer 96 of a sunflower 97. In practice this trailer is mounted directly on shaft- 92 but for convenience in illustration I have in this figure, shown it arranged to rotate about an axis at right angles to that of shaft 92 and driven from said shaft by beveled gears 98. It will be clear that the operative effect is the same. 99 designates a suitable keyboard, each of the keys of which is arranged when depressedto connect a corresponding segment of the sunflower 97 to a return (mnductor 100, so that depressing any key of the keyboard places said return conductor in electric connection with the segment of the sun.- fiower corresponding to that key. Suchkeyboard contacts are well known and I do not deem it necessary to illustrate the same in Return conductor 100 leads through battery 101 to stop magnet 102 and thence to brush 103 electrically connected to the trailer 9G. It will be seen that upon the depression of any key of the keyboard the circuit of this stop magnet 112 remains open until the trailer 9tiis upon corresponding sunfiowfcr segment, whereupon the circuit is completed, the stop magnet energized, and its armature 104 engages stopwheel 94 and arrests further rotation of the trailer, holding said t'ailer stationary until the finger key which has been depressed is released.

The effect of the operation of the current reversing commutator 495 is to place opposed sides of' the divided battery 105 alternately to liuc 10V). leading to the receiving printer. This printer comprises, besides the parts hereinbcfore described and illustrated in Figs. lil? inclusive, a polar relay 113 and a so-called separator relay 114, which are instruments of well known construction, being in effect ordinary relays. relay 113 vibrates with each reversal ofcurrent by conn'nutator 95, such reversals corresponding to the passa-ge of the trailer 96 rom one segmentof the commutator to another segment thereof. rPhis armature' is connected to a source of electric energy, and makes contact alternatelywith two contact stops 115 and 116 which are connected by conductors 117 and 118 respectively, to opposed coils of escapement magnet 36 of the printer, and thence to ground. It will bc clear that the effect of the operation of the armatureof relay 113, is to cause corresponding vibrations of the escapement anchor 32, and that. in principle -theeffect is the same as if this escapement anchor were on the In practice it is better to have the escapement operated by a local circuit, as shown, as the. instrument operated directly by the line will ordinarily be sensitive, particularly if the line over ltorrelay issomewhat sluggish, and thou h its 'armature is affectedV more or less 10. tact' with contact screw 121 until the armatureof relay l113 remains in contact with one of tsstQpS, 11'5 or 116, for a relativelylong escapementlmagnet 74; also through the branch conductor 124, to the magnet 46 of the'greaterpor'tion of] the rotation of .Sai

This missing of pulses I have overcome bymeans of the spring 133" ('Fi and 9) one end of which is secured to t e shaft 19 and the other end secured to the hub of said typewheel, and by providing a-certain amount of play between the key 21 on shaft 19and the'sides of the slot inthe hub of the type Wheel in which said key works; with this construction, when the shaft 19 first' commences to rotate, the typewheel may lag slightly behind the shaft, in-

creasingl the tension of spring 133, and then, l

as the inertia of the typewheel is overcome, said wheel springs forward again into proper position with relation to the shaft 19. In connection with the typewheel I provide an ordinary inking roller 134.

In the operation of the machine, a paper blank is inserted inthe carriage from ythe front, so that 4it is jheld beneath the type- "wheel 1 8. During the-operation of printmg space is provided above the top plate 2, and

between the rearcarria'ge guide rolls 17 and the escapementmechanism, so that thepaper may be fed backward until free of the carriesgo, and then-removedlaterally. This arf rangement of the parts `isg-particularly convelient inthe 'case'of a. prlnter doing com; mercial telegraph work, as it vpermits the use of standard te egraph blanks, and permits the receiving operator to read the message as printed and to check .any possible errors in .the printing, and at the conclusion of the message -to` remove the blank from the machine and by the same motion of the paper ieed rol-l 7 to introduce a neW .blank to prepai'e the machinefor the recelpt of another messae, the required interval between messages cmg thereby'rendered very brlef 1n. deed. f
