' type-wheel through a connection therewith comprising shalt 12. Said disklfl carriesla pair ol'radially project-- v'ing

arms

17, 17 which constitute strikers or type-actrj ators having such a length that when either of thenncoinsides with the shortest rad ius'from shaft 12 to templet ring 3, its end will project into someone of the holes 7 and push a type 8 from the corresponding pocket into printing position; while, when ,either-actuator17 is in a position at right angles to this shortest radius it `will l be withdrawn -from the holes and will clear the inner 75 sition of rest. The magnet-'member 1-1 has ,two

windings

18, 19, separated by aange or partition 20 formed onan inner core 2l which extends from one end to the other of the 1nagnet menrher and is paralleled' by an outer sleeve or case 22 inclosing the

windings

18, 19, and its, left hand end constituting the bearing studA. The core and outer case are made ofy'soft iron, and atv 4'ea-ch Aend of the magnet-member they present two Opf' posite pluies..4 The disklis made up oi kan outer soit iron ring 23 coinciding with the casing 22, an adjacent non-magnetic ring 24 coinciding Awith the winding 18, and an inner soit ironring 25 coinciding with the core 2]. lt will be noted' that the magnetic lines of' iorce mature 16 and out of said -.r11-mature by way of the other soft' iron/ring of disk 13 to the other magnet pole, and

any attraction exerted by said magnet has'a tendency to draw the armature lftoward that end and magnetically lock it to the disklS. Theoretically some longi `tudinal movement of shalt 12 is necessary in order to permit this, but in practice such movement may be made infinitesimal in amount. At the opposite end of the double magnet-member 11 is a soft iron armature disk 26 lixed to shaft 12. Itis obvious that-should the force of the left-hand electro-magnet predominate over that of the right hand magnet, armature disk 1G will 'be ldrawn against and locked with the revolving disk 13 so as to be revolved thereby, and if the right hand' magnet predominates, armature 1.6 will be released [rom the re volvingdisk 1.3 and brought to rest by the magnetic locking of armature disk 26 against the right end magnet poles.

27 isa fixed conrrnrrtator consisting of

segments

28, 110 28 and 29, .29 are two revolving brushes carried by

arms

30, 30 fixed to the underside of a bevel gear 31 in mesh With a bevel gear 32 ol equal size secured to the hub 'oll the type-wheel. The brushes 29 accordii'igly' rotate-in contact'with the commutator in synchronism with the type-Wheel l. Thcsebrushes are both electrically conf nccted with a continuons.conductive insulated vcon#` tact ring 33 on the upperside 'oi the gear 3l, from which current passes to the magnet, `as hereinafterv explained ,2.

through a brush 34'.

35 is a keyboard having a series ol depressible keys 36, l82 controlling

circuit wires

37, 37 connected with the respective segments 28 ol the commutator.' 'lhe conmutator 27 and brushes 29 constitute a-con troller or circuit-selector whereby every one of the keycircuits is twice in a revolution lolwthe typeqvheel put into condition to be operated, andit ai/ key 36 or 182 is de-k pressed long enough for one of 4tlnrihrushes 29 to pass- 'ovcr the commutator segment corresponding to tlia't4 selector'.` Current goes into said devices from the posii tive pole ol a battery 43 by way of a wire 42 connected with a binding post 45 shown 'in Fig.` 3, and goes out by way ol a Wire 44 connected with the brush 34. The

brushes

40, 40 are in parallel with the Wires`42, 44. The lett hand magnet-winding 1.8 hasits terminals '46, 46 connected with the respective poles of the battery 43 and a current ytherefore constantly flows through this Winding. T he right hand magnet-winding 19 is composed ol two circuits ol equal resisting andl clectmmagnetic qualities and having termina-

ls

47, 47, and 48, 48.

TheI circuit

48, 48 is connected directly with the opposite poles oi the battery 43 and the current flows through it continuously. When acting alone it creates a magnctismat the right hand vmagnet poles which predominates over the magnetism at the left hand poles created bythe winding 18. The

circuit

47, 47 is neutralizing circuit in parallel with the keyboard circuits and the brushes 40, and so connected with the battery 43 as to receive current in the opposite `direction to the current.

. in circuit 48,148, as plainly indicated bythe arrows, so

. netically locked in said position by contact of the ar-v that il both circuits are energized at the same time, they will completely neutralize eachother and' no polarity will be created in the right hand magnet. As the

brushes

40, 40, are in parallel with the member 4l representing the ke'y circuits through the key contacts and the circuit-selector, completing the circuit.througlrsaid brushes has the same etlect as completing it through Aany of the. key circuits.

The nonprinting condition of the machine is with the type-Wheel l, vclutch disk 13, and brushes 29 revolving in synchronism, lan d the actuators l7 stationary at right angles to their position shown -in Fig. 4, magmature 26 with the right hand magnet poles, this contact' being due to the tact that the magnet circuit 47. 47 is open; Now let a key 3G be depressed and held down an instant until the brushes 29 have had time to makt` practically hall acomplete revolution. The speed oi the brushes andl type-wheel is such that this `each 'half revolution ot the shalt l2.

period of time is very short. Contact will be made by one or the other oi the brushes 29 with the committator segment corresponding to-theI depressedkey at the same instant as the type character in the type. Wheel corresponding to .thatkey comes opposite one OA the actuators 17. rllhe same character will at this `instantbe oppositeeachfoithe tivo typo actuato1s,since there are duplicate'sets of characters in the two halves oi each row of types in the type-wheel, that is, in each row there are two complete alphabets or other sets oi characters. At the instant that the key circuit. is completed, theright hand electrounagnet winding becomes neutralized and the armature disk lo is locked to the revolving disk`l3. The actuators 17 are accordingly carried around with the type-wheel and the one which starts at the dotted position 1.7/ moves into the templet hole 7 opposite which it ,has arrived and pushes out the proper type 8 into printing position. Alter the said actuator has moved through an angle of lltlD and reached the )osition J7 it is arrested and mao-4 D iietically locked by the breaking oi the magnet circuit 47, and the type which has done the printing is pushed vvsaid brushes and brings the latter into contact with the succeeding conductive segment 38, .whereby the circuit is immediately maintained and the continued rotation ol the shalt l2 is insured. The circuit 47 hecomes broken as soon as the brushes 40 pass oiln from theisegment 38 0n to the other insulating segment 39, which occurrence takes place in exactly a halt revolution of all oi the described revolving parts from the time when the key circuit was energized.-

The magazine ring 5 is provided with a, cricmnlerential groove 49 engaged by two

studs

50, 50 on the end o a forked lever or yoke 5l pivoted at52 tothe machine trame 53. A spring 5l (Fig, 2) attached to said lever normally holds the type magazine in its right-handmost position with the lo\\'er-case row of types in register with the type actuators 17. rl`he lever is cn- -pableot` being oscillated to the lett to successively ister with the type actuators and the holes l. 7,tnnd

such oscillation is controlled from the keyboard in the following manner: 55 is a cam formed by the edge ot thel armature disk 2o and having two similar protu berant portions which operate against. one arm ot' a. bell-crank lever 56 pivote-d at 57 to the machine trame and having its other arm pivotall)7 engaged with n sliding shifter-rod 58 so to reciprocate said rod ont-e lor 'lhc cam is so shaped as to project the rod 5S toward the left. immediately when the shaft l2 begins to rotate. und keep it in this lelt-handward position until just belortl s-.tid shalt completes its hall revolution. 59 is a rocleshat't adapted to be oscillated to different` degrees by two pivoted shiit keys til, G2() whose inner ends engage un arm (501 on the endiolshalt 59, the outer ends ol said shift-keys abutting against stoppins G02, U93 which permit angular movements of different extent to'the two shift-keys. Attached to the shaft 59 is' an arm (i2A provided with two abutments 63, 64 of different thick ness. The Idepression of shift-key 61l oscillates the rock-shaft 59.to'a certainA degree so vas to bring the thin abutment 63 between theshifter-rod 58'and the yoke 51, and on the next left-handward reciprocation of the shifter-rod it will oscillate the yoke and shift the'iiiagazinering 5 so as `to bring its middlerow of I'types opposite the type )actuators 17 The depression of shift-4 key G20-osci`llates the rock-shaft 59 to a 'further degree and brings the thick abutment 64 between the shifterarm having the'abutments 63', 64 to move with the rodA tionary printing position, yet its'irnaga'zine'ring may rod 58 and yoke 51 which causes the magazine ring to be shifted to a further -degree to bring its right-handmost row of characters into register with the type actua'- tors. The shank of varm 62, as 'shown in Fig. 13, is made thinand resilient so as to'permit the upper end of the 58' while therock-shaft 59' remains axially immovable. When neither of the abutments 63, 64 is between-the rod .58 and yoke 51 the rod on its left-handward reciprocation approaches the yoke, but does notoscillate ,it-. Thus it will be noted that while the type-wheel'ln'has a stabe shifted axially to alternatively associate any vof 'itsrows of types with the type actuators and with the keyboard circuits, which include the segmentsvof the circuit-selector. It will be observed that as a conse-- quence,'a given number of key circuits and commu-` vtator 'segments controls a nnkltipleA of that number of alphabets and other sets of characters on the type-wheel. l may employ more or less than two sets of 'characters in the periphery ofjthe type-wheel-anda corresponding'f numberpf type-actuators and selector brushesi.

G5 is a cylindrical platen-roll mounted with its axis parallel to the axisof the type-wheel 1 and adapted to receive a rotary movement to-coperate with the typewheel inprinting the characters, and to space the char-- actors' and words, and an axial or longitudinal meyement to space the lines. The web or paper 66 is' secured -'by one of its-longitudinal edges to the platen-roll by moans-'eta clamp consisting of a series of fingers 67,

mountcdhvithin the-platenfroll on-arock-shaft 68,

which. runs'longitudinallythereof and is provided,

'with a handle or lever 69 onitsright hand end. The

.opposite `edge of the paper is left free.- When swung to the right from the position shown in Fig.. 3, the lever:

69 opensbt e clamp so as to release the paper frombef tween the fingers' 67 and the opposed wallY 70 of the platen-roll, forming one side oi a slot in which the clamp is located, and when swung tothe left to close the clamp,

72, 76 designate two'sleeves constituting a rotary platenrollholde'r iu which the l.roll 65 is mounted and to which it is attached in a manner to permit axial movement but to preventrotary movement of the roll within the holder, by two spline-keys .7 3, 7 4 (Figs, 2 and 4) formed on'the respective sleeves 7G, 72- and operating in a slot v75 extending for the length ot the platen-roll. The two sleeycs rotate about la hollow bearing 77 formed on the machine frame, and the sleeve 72 is provided with a gear 78 connected by

gears

79, 80,l 81 witha gear 82 xed to thtl shaft 12, the gcar79 being loosely mounted on shaft 12. The relation/between the pitch diameters of gears 78land 82 is such that a half rotation of the shaft 12 imparts to roll-holder and plate'nfroll one complete rotation an additional fraction equal to a character s paceL In printing a line therefore, each depression o a character key results in starting the platen from a position of rest, which always corresponds tothe position 17 of the actuator and is about 90 from the printing point, and 4carries it through a complete rotation'back to thefpointywhere it started, plus one char'- acter space, thereby leaving the roll in position to receive the next imprint in the space following the last `printed character. For spacing between wordsa spacekey 182 is provided on Athe keyboard, controllingacirl cuit which corresponds with a portion ofthe type-wheel i periphery on which there are no types? v The line-spacing axial feed of the platen-roll`65 .is

.effected by a pawl 83 mounted on the sleeve'72 andgcol operating with theteethofa central .ratchet rod84 mounted on the roll 65. 85 is a'yielding check-pawl attached to the sleeveV 72. andengaging the' 4teeth of ratchet-rod.4 The pawl 83 is carried by a lever ,86 pivoted at 8 7 .to the sleeve 72 and'having its return throw adjustable by` means of a set-screw 88, said lever having and goes on to anew line without any attention oract 'mechanism, the platen automatically shifts to the left I roo o the operator. Provision is made whereby, when the ofcharacterspaces,l the platen-roll will automatically remain in rotation until it has spaced out the remainder ofthe line and automatically shifted to a new line, said -provision being as follows :--92 is an insulating ring yse- 'uous contact with those ends ofthe brushes 40, 4() which areA opposite to the 'ends contacting with the

rings

38, 3 9. In this ring 92 is mounted ametallic contact seg, ment 93 of a length corresponding to acertain. number solute rotary position, orposition betwee'printing cycles of the platen-roll, does not bring it underneath the brushes 40, 4Q until the end "of theline is ap-A proached; '[he segment 93 never comes to rest' under-Y neath the brushes, or as soon as the'platen-roll has an absolute rotary position which would bring the scgment to rest under the brushesafter. the vnext rotation,

the completion of that rotatonfmds the circuit 47 47 still completed through the brushes 40,. 40 by way of the segment 93 and compels the platen-roll to remain of character spaces, say tive, and so'loc'ated that itsab-` end of a line'is approached to within a certain number cured tothe periphery o ffsleeve 72 and having-contin in rotation until the segment 93 is' no longer under the brushes 40 in-the natural position of rest of the platenroll. It follows from' what has been said that as the end of a line is approached, the operator has merelyto depress the spacing key 182fandhold it down until the segment 93 would ,come under the brushes 40- at the end of its nextA rotation, after whichl he may release the key andthe machine will automatically space out the los line andshift to a new one. The segment 93 is embedl ded in an insulatingsegment 94 which is removably mounted in a dove-tailed groove in the ring 92, and the extra equipment of the machine preferably includes a number of substitute segments 94" 94" (Figs. S and 9) -having Contact `segments l93, 93" corresponding in length to differ-ent numbers of charac-Ltr spacts, said substitutesegments being adapted `to be inserted'iu .ring 92 in place of the segment 94, so aste start the automatie spacing earlier or later in the line. ily adjusting the stop-screw 88, the throw of pawl 83 may be `variedso that`i t feeds one or more teeth ot` the ratchet rod at cach stroke. thereby varying the spacingbetween lilies. .l

The ratchet rod 84 is'rotatively mounted in bearings at its ends and is provided at. its right hand end outside oi the roll 05 with-a handl-'J-slecvc 95 splined to the rod` \'\'ithin the roll 05 the sleeve 95 is provided with a clutch plate 90 having a tooth or project ion 97 adapted to enter either ol two notches 9S, 99 formed in a fixed clutch plate 100. A'spring 1.01` normally presses the sleeve to the right: and 'also'tends to rotate it and the ratchet rod ina direction to bring the teeth o the ratchet; rod into their normal position oi engagement `-ment with the notch 98. The slet-vc'95 may, however, by'lieing pressed inwardly to disengage the tooth 97 from .the notch 98, be rotated and the ratchet rod turned out of engagement with the pawls and held in ,its new position by the tooth 97 entering the notch'99. 'lhe platen-roll `being thus disengaged from its axial 'ieedmechanism may be moved by hand to any new line position and rengagedwitlrthe leed by returning the rack into rengagement with the pawls'. pin 102 tlierotary movements of the rack.

The irictional engagement oi the pawl and toothed wheel is sutlicient to prevent, relative rotat-ion ol the gears 80, 81 during the' ordinary rotary movements oi the platen-roll imparted by the `rotation o1 the shaft 12, but permits such relat` rotation when theoperator grasps and iorc-ibly be manually rotated to brinaA it to anypoiut in a liuc 'independently of its rotary leed mechanism.

or othcr suitable material, having holes litiregistering with the sockets 114, but'too small to permit the downward escape oi the keys, the edges of said apertures constituting inner key-seats. 'lothis plate is carried the wire 42A tallic piungers 117, spherically concave on their upper sides to tit the keys, and located in sockets in a thick insulating plate 11S, said plungers being .pressed upwardly by metallic springs 119 bearing against binding yposts l2() connected with the wires 37. ing-key 182 which is elongated and cylindrical, is preferably supported ata plurality of points along its length by plungers 121 which are cylindrically conavc on their upper sides.` 'lhe keys Ilo and 182 are normally pressed upwardly hy their springs out of contact with the plate .115, and when any oi them is depressed the corresponding key c `-cuit is completed through the plate 1.15, key 110 (or 182), plu/nger 117 (or 121). spring 119` and binding-post 120. vThe keys 3G,

182 and their inner key-seats .11G constitute the clec- 95 trodes ot' the key-circuits.V The spring pressure under 'the keys is very lightl and the distance through which they have to move is small. The particular object oi this design .oi keyboard is to permit the keys to be o ieratcd bv a wi )ing movcmentoi theo )eratofsiinffers yi t s in contact with the linger-board, thereby avoidingV noise and excessive linger action. Said movement in whatever direction made will tend to rotate the spherical keys 30, and ii made in an ruiproximately forward and backward direction, will tend to rotate the spac- '105 more-keys which maybe adjacent to cach other and in line any where on the board to be included in one movement oi the linger; (/haracters which occur in often-used groups can be associated on the board so as to effect by this wiping movement a considerable saving in time, labor, and movement on the part oi `the operator.
