J The key levers 1 are pivoted `at their rear ends by bearing upon a cross bar 2, andthey overlie the universal bar3 provided at, its ends with rearwardly` extended arms 3a that are pivoted at 4. tothe base of the machine. A link 5 extends throu h a-lug 6 on the unii i as a concave under surface tolwhich is fitted the conveX'surface forms an adjustable connection which allows anA easy pivotal movement of the s ace frame, which is made up of the universa and its rearwardly extended arms 3a, and without liability of the parts binding. The upper end of the link is pivoted to an arm 9 s flied to a rock shaft 10. 'A clutch section 1 1 (see Fig. 4) is fixed adjustably to this rock shaftl and the tooth or end projection thereof loose collar or clutch section 12 which carries a rearwardly extending arm 13, to the rear endl-of which is pivoted'a link 14, (Fig. 3) that has the uiper'end pivoted at 16 to a holdi dog o the escapement mechanism.. l TheI ink 14 is. referably made of two parts thatare united y a turn buckle 17 in order that the link may be lengthenedor shortened at will. -Theholding ,dogor pawl 15 has a 'laterally extending tooth 18, (see Fig. 8) with .avertically disposed edge to engage the, .teeth-.19 projecting laterally from thefeed rack that is 'earned by. the carria e'. l holding dog is pivotedat 21 ,(see i 3).to

A detcnt or feed og 26.is pivotally connected with the standard 22 by a in 27/ which projects from the standard an passes through a Y slot .28 in the feedvdo to permit a longitudi-v nal movement thereo in the direction of the travel of the rack as well :is aswinging move- 7 ment around the pin 27 and at substantially right angles to the rack.

In this movement, however, the tooth of the holding dog is brought into lthe path lof the next or advancing tooth' of the feed rack 19 and when the feed dog releases-the rack, the paper carriage moves toward the left and the holding dog will be in position to arrest ,its movement when the carriage has moved the distance of one letter` 15 s ace7 or one tooth of the rack. The feed dldg 26 when released in the manner described is pressed to the fight and downwardly by a spring 32 which engages the said dog ata point above and in rear of its pivot and as-soon as the feed dog is raised out of engagement by the holding dog it is forced by its spring to the right .the distance of one vtooth `of the feed rack and is moved into engagement with the nexttoothfthereof. The :cam surface or projection 31 is formed so that the feed do can engage the next tooth on the feed rac ,before the holding dog; begins f. to descend and for this urpose the cam suryface inclinesdownwardly and to the right or. it may be made sufficiently narrow to simo f yply lift the feed dog through the pin and then When the feedL dogis moved tothe right by its.- spring the said `pin simply drop w off of the projection 31,y thus permitting the -feed vdo if f mentfwith Yther-rackimmediately after its relea'se and thereis no possibility of the carcapement 1s provided.`- Y' The artsare so related and timed that the feed .dog effects this position andbeforethe holdin'gjdo begins sgdescrendingmovement.Y Whent e holdrngfdogreleases the te eth. 19 of 'the`rack, the .feedzdeawhh'halggd a tooth-29 and inovespn step .withL-therack and carriage to engage the next toothon the* rack. rom thlseonstructigon it will be seeni that,fthe,feed dogagain effects an engageriage skipping anda quick and efiicie'nt'essecondengagement with the teeth 29" of'the r'ackbefore the typebarleaves the printing revents anyisleeve"49 hasan upwardly extending arm or has made its imprint and has and is at a distance approxilaten. By the ereinbefore described7 the releaseor escape of the carriage may be obtained with but slight movement of the holding d og.

Carriage release-In order to release the carriage from the escapement so that it may be moved freely in either direction I provide a vertically disposed release rod or bar 34', (Figs. 3, 4 and 8), having an inwardly turned upper end 35 extending under a pin 36 on the feed dog 26. This release rod is guided through a bracket 37 of the post 22 and at its lower end is pivoted to a lever 38 connected with a hollow rock shaft 39 journaled in the base of the machine (Fig. 4). A keylever 40 is connected to the rock 'shaft and has a key 41 adjacent to the keyboard s that by de pressing this key theI release rod 34 will be elevated and the feed dog will be lifted from engagement with the feed rack and the earriage will be free to be moved' in either direction. In addition to this carriage release mechanism'I employ a bar 42. (Figs. 8 vand 8a) having inclined slots, through which pass screws 43 that `take in' threaded openings in the bar.20a, of the carriage which supports the feed rack so that by pressing upon the thumb piece 44, (Fig. 1), at the left of the carriage, which is operatively connectedhto the bar 42 it wil-l ride up on the screws 43 and its edge'engaging with a forwardly projecting s urv45 on the feed dog will lift the'dog and tlius free thecarriage. By the employment of carriage release -ust described the carriage yin addition to 'being released can be positioned as desired by the operator, whose hand is at this time onthe carriage and conftrols its movement; that is it can be pushed toward theright or it can be allowed to move any distance toward the left under the action {fits springdrum 46, which is connected y with thecarria'ge by a' strap 45', Fig. 3.

Type' bar action-#The type bar action oonlsists essentiallyof a series foftype bars 54 (seei Figs. 1', 2, 7, 13' and.14)pivoted to a segmenlaten, the said type bars inclining upwar y toward the with `their upperends upon a stop rail 56.

l Links 57 connect the lower ends of the type bars with sub-levers 58 and from the forward ends ofl these sub-levers, links 59 extend down to connect with the key levers 1. The

'sub-levers have laterally extending pivot "r pins or trunnions engaging a groove 6() formed in a slotted segmental bearing 61, supported on posts 62 of a platform 63, which platform also carries the arms 64 which hold the stop rail or'rest 56 for the type mit which prevents the pivots from being unseated from their bearings in the lgroove. The sub-levers are under tension of springs 68'(Fig.`1),whichare l l' selves lproperly disposed in their slots.

By

these meansthe tension'oneach spring mayr be varied and the springs are accessible from the front as the space between the platform and the bar61'is unobstructed, the posts62` l scale. 77.

being arranged at the ends of the bar.`

The segmental bearing 55 consists-of two 1 Earts'55, 55- (see Fig.' 13) andthe latter part oovem its as a longitudinally. extending 'pintle's' or trunions of the type bars and both parts are slotted transversely asV shown 1n Figs.l 1"and'2', to receive theI type bars.' The f par`t`55 is removable so that any type bar may be taken out but as the pintles 4rest in lthe-lowersections of the crown, the other not be disturbed vin-re'moving any one ofthem. The slotted portions of the .bearing are of such lower part thereofis' equi-distant from4 the shape that all except the p ntle recel ng groove so that'the wearing Vsurface' of the type bars is substantially eircular' in form in. order `to reduce friction.

Projecting ing surface and the friction between the type each type bar a projection 71, (Fig. 7 4is arranged opposite the space between the upper and lower case type on theface of the'bar. \This -projection is slightly greater than-the height of the type so that in case two keys are struck about the same time the type on the in contact with the back of the bar which is at or adjacent to the printing point but the body of the last operated bar will strike the projection 71, of the first Iactuated bar, as shown in Fig. 7, thus preventing the type from being damaged by the clash.

rounded and hardened so as to resent a small surface and avoid friction, and extending rearwardly from the guides are arranged projections 73, (Figs. 1 and 2)', which extend to and terminate at the line of 4printing which is indicatedby the'dotted line 74 in Fig. 2.

remova le and adjustable pieces for determining/the pro er positioning of the pa er with relation to t e printing line.

aper fingers extend partly around the platen and guide the paper afterit leaves the paper feed roll 76. These fingers are adjustably connected to the scale 77 carried by the support 78 of the upper feed roller 76 and the fingers are provided with indicating lines 79l Which'are'a ined with the printing line so scribed to adjust or position the pa er with .relation to theprintlng line, when lling in partly printed blanks or for the purpose of makmg corrections etc. likewise' vprovided with a printing point indicator V116jwhich. is located `adjacent to the printing point and co-operates with the Ribbon l'movement: The ribbon -80 l(see Figs. 1 and'2) of a vibrator 82 which 1s secured to' a bent downwardly extending bar 83 which slides in guides` of the bracket 84 which supfport-s the l:segment 5,5 While the vibrator itsel slides in fixed guides 82 on the arms 72. The slide 'bar 83 is slottedy at 85 (Fig. 2) and has a pin '83". (Fig. 1) which is engaged by the forked end of anv arm 86 that isfxed on a rockfshaft 87, ournaled inthebracket 88. The rock shaft as an arm 89 connected by. a link 90 with an arm 91- fixed to the rock shaft 10 before mentioned; so that eachtime'the rook shaft 10 is moved by the depression of key, and upwardly from the position shown 1n Fig; 2'to a position where the ribbon will f cover the printing point and be interposed in bars,- and their bearings..

bars.` The arm9 1 is slotted and the link 90 is adjustablyconnected therewith, so that the vibratorcan be given a longer or shorter throw and the ribbon can be movedv transversely to a greater or less extent to bring different portions of it over the printing point. From the vibrator, the ribbon extends toward the ends of the machine around rollers 93 and thence atright angles toward the front of the machine 'over rollers 94, and thence downwardly to the ribbon spools 95 which are arranged so as to be easily accessently of the spools and in either extreme po.

sition one of. the clutches 99 Vsecured to the shaft near the ends thereof, will engage a tooth or a pin 100.0f the associated ribbon spool, so that one spool will turn with the' v shaft to wind -the ribbon` while the other spool is free to unwind. The shaft has a button 101 at each end by which it may be moved in a longitudinal direction to throw one clutch out of engagement with its .spool and to throw theother clutch into engagement with its spool. At .about the center of v the shaft 96 is splined a worm wheel 102" which is held against longitudinal movement on the shaft by apertured lugs 103i through which the shaft extends and .which are locatedl on opposite'sides ofthe worm wheel and. project from a bracket 104 attached. to

the segment supporting bracket 84. This bracket 104 supports a shaft 105 which extends at right-angles to the shaft 96 andhas a worm wheel 106 at one end thereof that engages the worm 102 of the ribbon spool shaft. AAt its opposite end the shaft 105 has a ratchet wheel 107 engaged bya pawl 108 that is carried by a gear wheel 109 thatiis lloose on the shaft 105 and which meshes withf al rackI 110 secured to the front bar of the 'paper carriage. By this arrangement each movement of the carriage in thedirection of its feed will move the rack 110 and lthrough the gear 109, the ratchet mechanism and the worm gear connections will turn a ribbon spool shaft to move the ribbon lon,- gitudinally'lacross the printing point. On

- the return of the carriage to the right, the

gear 109 rotates in an opposite direction, carrying the pawl 108 freely over the teeth of its ratchet Wheel, so that the gear 109 simplyruns free and do'es'not effect a feed of the ribbon. To the bracket 104 is pivoted a latch 111,

`the end of which engages in a groove 112 in pins 114,115.

The ribbon .key attached thereto.

the ribbon spool shaft.

The latch is conopposite end connected to the bracket, and the movement of the latch is limited by the sto a When the ribbon spool sha `t is moved longitudinally the latch will be car- .ried around its pivot with it, together-'with the upper end of the spring 113 and the force of the spring will accordingly be exerted on the shaft in either direction and tend to maintain the shaft in the longitudinal position to which it has been moved.

Paper carriagez-The paper carriage comprises a frame 117 arranged in inclined position and having bearing rollers that run upon stationary tracks` 118, 119, supported from the base ofthe machine. The rollers have trunnions with which cone bearings cooperate; the bearings being held in place by set screws as shown in the detail Fig. .15. The track 118 isI supported upon a shoulder 119 ofthe post 120, by a screw 121 and the track is grooved on its upper face to receive the carriage rollers and prevent lateral displacement of the carriage, whereas the carriage is held against upward displacement by small rollers 122 that extend under the track 'rail and project laterally from depending arms that project from the carriage. vThis arrangement allows the carriage as Aa wholeI to be run off the tracks, when desired, without dismounting the tracks or rollers. The platen is journaled in a frame 123 which is connected with and. supported from the carriage frame 117 by parallel links 124 and 125 so that the platen frame may have a transverse shifting movement to change from the lower to upper or from the upper to lower ease printing position. The links 125 have 'downward extensions which carry a cross rod 126 that extends across the machine and is engaged by the fork of a lever 127 fixed to a rock shaft 128 that is journaled above the base of the machine. This rock shaft is connected by an arm 129 and link 130 with the key lever 131, which has the upper case By depressing this key the forked armi will rock the links 125 IOO and shift lthe platen frame-with the platen and the platen frame being arranged on any incline will drop back tothe lower case printing position by gravity. In order to revcnt shock when the platen drops back an to render the shifting movement of the parts easy,

a contractile spring 132, (Fig.2) is connected at one end to the'platen frame 123 and at its opposite end to the ,carriage frame 117. `Paper feed Tolles-As before stated the paper feed roll 76 (Figs. 1, 2, 5, 11 and 12) is. carried in supporting arms 78. These arms are pivotally supported upon a cross bar 78 carried by the brackets 133 (Fig. 1) forming part of the platen frame and curving about the under side and to the rear of the platen. As has been heretofore pointed stesse out the arms 78 supporta platen scale bar 77 o n which paper guiding fingers 75 that j carry margin feedrollers 75 as shown in Fig. 2. The-,rollsupporti-ng arms 78 are underpressui'ei of leaf springs78 (Fig. 5)/secure'd Lof vthe platen frame.

Thesev fingers 75 thereto and bearing upon the front bar 123 The lowersetof paper feed rolls 76v are'earried on a shaft 7 6" jourings Ibefore mentioned. The arms 76 arepnderlpressure of leaf lsprings 76 each 'naledin arms 7 6'/ extending from a rod or rock shaft 761. which is journaled inthe beardgatojne end to the pa er shelf 7 6d so lower paper feed rol s willbe forced againstltheplaten In order to Vrelease both setsefrolls and the margin feed rollers from 1 (Figi the-platen simultaneously I provide a lever 134 securedfon the left-hand end of the shaft {erockshaftfwil be turned so rejections 76" an '7 64f` thereon move respectively the supports 78y ofthe up er feed roller and margin feed rollers' andft eshaft 7&6" ofthe lower setof Irollers ftoimove the rollers away from the platen, it" being 'understood by reference to Fig.. 3 th'a'tthefarms or projections' .76f enc- `tendfaeross the front side of the shaft 7 6.

L'tnespac'e,mechcmism-At the left of the platen there isfa ratchet wheel 135 (Fig. 16a) wlth which engages apawl 136 ivoted at 136.L to a/stud. 13T-which is swive edl n avertically disposed pivot .to one Varm of la bell F crank or angular lever 1-38that ,isivotedto eiplaten, the `other arm of (Figf'') t"anlarI n1-41 .on the rock shaft 50. Thisrock shaft 50 extends fore and aft of the i machine from lthe rear-'to the front .thereof through the hollow shaftqor sleeve 49 herein-j before-referred to, and has an upwardlyeX- 4tend-in 'actuating'arn-jr lever 48adjacent to the eyboard (Figs. 1 and2'). `.By movmg this armthe linespa'ce'pawl will be operated through the 'intermediate connections lto turn the platen step by ste-p forl the line s acing.

This roller "also serves yin connection with the locking lever 143' to insure the accurate positioning of the platen at each line space movement and there is no liability of the roller riding up on the teeth or an overthrow of the laten as might-be the c ase were the locking ever omitted and the i` roller alone relied upon. This might result in an irregularity in the printed line'7 as the l jarring o the machine might cause the 'platen to turn slightly after the line of printmg had been begun and to continue to turn until the roller res-ted in the lowest position. between. the teeth and this would cause the first part of the line't'o be out of alinement with the last part, which latter part only Inorder I i would be in the correct position. to change the spacing ofthe lines a controlling piece or adjustable device 148 (Fig. 16a) is carriedpivotally by the forward upturned 136 moves in the same plane as the line spac- Yeo and' it is normally vout ofengagement w1t fthe ratchet wheel'andthe platen 4can therefore be turned in either ldirection by turni'n either ofthe finger wheels-at the ends thereo The pawl` 136 rests upon theroller 145 and vwhen the platen is turned the roller is lifted -sli htly by the'teeth so that the awl parta ing 'of this movement 'will be 'fted still. 1 has Iing wheel and the throw thereof is regular or IIO fa' cutout portion with an incline on' am 'edge- 136b which-enables the pawl to maink tain en agement with' and to follow up the' teeth e the line `spacing wheel as aline space ing movement is transmitted vvto thevplaten and to' disengage the pawl from the teeth of the wheel during 'the forward orreturn move-v ment of the pawl.4 In the upper side of the Vpawl 1.36 anotch 149 (Fig' 1) is formed and y lifting the awl this notch is engaged by a cross bar 150 6) of the guide 151 on the which guide the pawl ex- .erting pressurelon the parts, will serve to vhold the pawl, the arm 146 andthe roller 145.; f elevated, so that vthe platen will be perfectly free' and may be adjusted without regard' to the ratchet teeth and roller. anism themaehine is adapted for vuse in fill- By this'meeh- .izo

When it is desired to return the carriage fora new line and at the same time turn the platen, the arms or levers 48 48, are grasped between the' thumb and forefinger and pressed together and both arms are then moved together toward the right or if desired the same result may be accomplished by merely swinging the finger piece or arm 48 from left to right. From'an inspection of Figs. 1 and 2fit, will be se'en that there is a forward extension 48X on the. arm 48 with which the arm 48 is adapted to contact after the line spacing movement has been` effected so that the two arms will move tol gether.

But there is, nevertheless, no n ecessity for moving the two levers to ether to effect the line spacing and return o the carriage because a single movement of the arm 48 would be effective for this purpose. By

f returning the carriage through the arm 48 by the co-operation thereof with the arm 48 the line spacing mechanism is relieved of the strain incidental to returning the carriage `by a pressure exerted through said line spacing mechanism. When it is desired to return the carriage without spacing for the line it is simply necessary to turn the arm 48.

From the foregoing description it will be seen that the axis of the pivot 136a ofthe line spacing pawl 136-extends parallel to, or substantially parallel to, the axis of the/platen, whereas, the axis of this vertical pivot which unites the part 137 to angular actuating lever 138 is at right angles to the axis of said first mentioned pivot, so as to form a universal joint between the line spacing pawl and its angular actuating lever. It will also be seen that the rock shaft 50 extends fore and aft of the machine'and that the movement ofthe substantially horizontally disposed line spacing pawl is fore and aft of the machine or in the general direction of the length of said rock shaft and that the lrocking motion of- Isaid shaft transmits a line spacing movement to the pawl through the universal joint. Furthermore, it will be seen that although the line spacing mechanism is carried in part by the shiftable platen frame and in part by the framing of the machine or a part that l Vremains fixed during the case shifting move- \ments'of the platen frame and that although the dierent parts of the line spacing mechanism' are positively connected,theyy do not interfere with the platen shifting movements nor do the shifting movements of the platen frame affect the line spacing mechanism.

I show in Figs. 11 and, 12 amodified arrangement of paper feed roll'and paper fingers in which case .the arms 7 8 are substantially the same as the arms 78 before described, being pivoted to curved brackets 133 of the platen frame. The'ends of these arms 78 carry the paper roller 76, and the said arms have .upward extensions to which the graduated paper scale 77 is attached on the under side. Arms 78',1 are pivoted to the platen frame outside lof the arms 78 and carry at their upper ends a cross rod 7 8b on whichl slides a block, carrying the paper fingers 75 which areprovided with small rollers 75. The arms 78 on the opposite side of the feed roller 76 carry the cross rod 78C and the paper fingers have tail pieces or extensionsv bearing upon this cross rod. Springs a attached to the platen frame bear upon the arms 7 8a, land the paper fingers are made of spring metal and are of such form that when the arms, are pressed by the springs a the fingers will be under spring tension and the roller carried thereby will be held against the platen so that after the paper leaves the feed roll 76 it will beengaged by the paper finger rollers. rThe feed roll 76 and the arms 78 are forced toward the platen by the pressure exerted on the pivoted arms 78a 'and rods 78h, by the springs a. The arms 78X may be operated bythe lever 134 as before described and when so operated the paper fingers and the feed roll 76 will be released from contact with the paper simultaneously. The paper fingers can be moved lor adjusted along the supporting rods longitudinally of the platen to properly position them to co-operate with paper of different widths.

,[will now describe my improved combined carriage release, line lock and marginal stop device. Within the hollow shaft 39 (Fig. 4) is a shaft 151x, to which are respectively attached the forwardly extending lever 15.2' and the rearwardlyextending lever 153 having upon its rear end a forked shaped portion 154 whichengages the shaft 155, (Figs. 1, 3u and 4). A line lock lever156 having an elongated eye 157 (Fig. 4), through it at its rearward end is located directly over a hole 158-cut in the base plate, and over the forked arm 154. The shaft 155 operates within thel eye 157 and turns, through an eccentric portion thereof, the lever 156 upon its fulcrum 159, and throws the forward end of said lever under the arm 9, thus locking it against movement, and preventing the types from striking the paper upon the platen. The manner inv which this shaft 155 is turned will bc hereinafter more fully explained. As before described when it is desired to release the carriage, so thatit may be moved in either direction, the lever 40 is pushed downward by depressing the key 41 upon its forward end, marked Carriage release, which raises the lever 38 and the release bar 34', thus lifting the feed dog from the rack. From an'inspection of Fig. 3a it will 'be observed that a bell 160 is attached to the bracket 161 and that the lever 162 carries a hammer at one end and a bell trip 163 at its Ich yIO

other end, to engage with the pin 164 on. a

bring the pin 164 lin such position that the bell Will be sounded several letter spaces .be-

fore the end of the line is reached or before the pin 164 engages with the stop 166, and

andthe carriage against further movement.

vWhen the pin 164 strikes the belltrip 163, it

carries the upper end ofthe lever 162 with it until the .p in moves-out of Acontact with the trip and the bell hammer drops by gravity upon the bell and sounds the-alarm. A stop' pin 167 pro `ects fromthe 4bracket at a point Where it wil arrest and normally maintain the bell lever out of contact with the bell. The portlon ofthe lever-162 which carries the hammer may`be made resilient, to permit the ybell hammer to spring down When ythe lever strikes the pin 1.67 and thus' strikev the bell and then rebound and remain at a short distance from it. The trip 163 is pivoted upon the upper end piece 168 (Fig. 3b) that normally rests against the lever and is heldin thislposition by gravity. The relation of the parts is such that when thecarriage vis moved from right rto left, the pin 164 will contact with the trip and cause the lever 162 to move with, it to sound vthe alarm. When, however, the pin 1.64 contacts With the trip 163 in the return movement of the carriage toward the right,

thetrip will merelybe turned on 'its pivot without moving the lever 162 andwithout sounding the alarm.

The vertically disposed shaft 155 hasits bearings in the projecting portions of the. bracket 161 and on its upper end is secured' the stop .or-dog. carrying block 1 69 which is shown in detail in Fig. 3e and Ito which are l pivoted the stops or dogs 166i, and 166 as tcarrlage like pie.ce r strip of metal 17 5, Figs. 1 and.` 3, forming abed for the sliding rods 165 and shown which are at diiferent heights (see Fig. 1). .To hold these stops in theirproper'and normal position the springs 170 (Fig. 3e)

' which are each secured at one end to the carrier, are made to vbear against the rear ends of saidstops 166 and' l166'#I` At the lower end of the shaft 155 a groove is cut to-receive the forked end154 of the lever 153, (see Fig. 1), and around the shaft 155 -is a coiled expansion spring 171 theA upper end ofwhich is connected to thev bearing'17 2 for the shaft, the

abling the operator to readilyv adjust the bars and thus regulate the margin, and the lineA lock mechanisms so 'that mai-y be set to operate at any desired-point.

n the bracket 161 is apin 177 (Figs. 3&3o

3d) which extends into a recess in the-circular base 178 of the stopblock 169 so as to limit the turning movement ofthe shaft 155 and l the block 169 carried thereby.

The operation of this margin regulator and line lock is as followsz-Suppose 1t 1s deslred` to lock the machine at the polnt on the' the alarmv they scale, thus leaving say a margm of five letter' hand edge of a sheet of spaces on the'right the operator ralses the aper.-' `To do this atch 17 6 on left hand end of carriage, draws` i out the sliding bar until the' proper nu# meral in the graduations on the bar comes "under the latch, then the latch is' dropped into a notch at that oint and thel operator proceeds to write. preaches the end of the line the pin`164 will first vibrate the bell trip and hammer and the alarm will be sounded.

155 is turned back to the normal position it' carries the forward end of the lever 156 from under the arm 9 and thus unlocks the machine. If the operator desires to regulate the left hand margin on the paper so that the printing will. begin at say ten letter spaces from the side, he simply raises the latch 176 on the-right hand side of the carriage, draws out the bar 165 until ten letter spaces are indicated by the graduations on the bar, drops the latch Y into the 'notch which has been brought beneath the latch and proceedsto write. This adjustment of the bar draws the pin 164 ten letter spaces toward the right 'and itcomes in contact with its stop 166 ten lspaces earlier than when in position to permit a full travel of kthe carriage to the right yand makes the margin uniformly tenspaces from the 4beginning ofthe line. Should the operator desire to write notes within the margin, it is simply necessary to depress the line lock key; which raises the shaft 155 and the stop 166 is raised out of the path of the pin 164 when the carriage can bey moved to the eXtreme right. i

It will be observed that the

stops

166 and 166 are placed on opposite sides ofthe block or carrier 169 and are free to move around their pivots independently of the carrier in opposite directions, so that when the carrier is raised to enable the operator toeither write within the margin or to add one or more characters at the end of the line the reverse movement of the carriage past the stop will cause the pins to move their respective stops around the pivots thereof without turning the shaft 155 and without interfering with the free movement of the carriage.

From the foregoing description of the line lock and margin stop mechanism it will be seen that the linelock stop 166- is carried by the frame of the machine and has three motions, one a swinging motion with the bar or rock shaft 155 at the end of a line to effect a line locking operation; another motion upwardly with the shaft 155 to take said stop out of the path of the co-operating stop on the carriage, and a third motion an independent pivotal movement on the'block 169 without moving the rock shaft, to enable the co* operating stops to passone another freely in the return movement of the carriage.

Certain of the features herein shown and described are not claimed herein, but will constitute the subject-matter of separate divisional applications.
