Each type bar is pivoted at 7`na type br hanger 8 secured to thefront ',f'a'ce ofthe segment 3 by screws 9. Each typebarfhas a pull link 10 connected thereto, lthe'forward end ofsaid link beingpi'vot'ed at 11 'to an actuating lever'12 pivotejdvfatl 13 to] a' fixed portion of the machine. f A key stein 14 carrying a finger key 15 isjpivoted'a't its lower end, as at 16, to the associated actuating lever 12.

N o. 782,859, hereinbefore referred to.

' Substantially horizontally disposed parali lel links 32 are connected to the shift rail and to the frame of the machineto guide the shift rail and the parts carried there by in their case shift movements. Thus, the forward end of ea'cli link 32 is pivoted at 33 to the shift rail, whereas the rear end of yeach of' said links' is pivoted at 34 to the frame of the machine. The shift rail carries depending arms 35 to the lower ends of which are pivoted, at 36, a second set of parallel links 3T. These links are pivoted at to the frame of the machine and are extended rearwardly beyond their pivots 38 to form arms or links 39'which -are fixedly lconnected with a tie-rod or cross bar 40. The shift rail and the parts carried thereby are thus 'supported for case shifting movement under control 'of suitable case i feed vdogs 42 and 43 are pivoted at 45 i seen that the engaging tooth of the feed dog "rack, as indicated in 42 extends upwardly from. its lever-like carrier 48 of which it forms a part, said carrier bein Y first or` er. This lever-like carrier is mounted on one side of the plate-like dog rocker 47 and the engaging tooth or dog thereon normally engages ay tooth of the feed Fig. 1, and constitutes a holding dog. The carrier 48 of this dog received in a cut-out portion 49 (see Fig.

6) in one side of the dog rocker, and a contact portion 50 on the member 48 is adapted to overlap and-engage a contact portion 51 on the dog rocker, in order to limit the turning movement ofthe dog carrier 48 in one direction around its pivot `45. The dogcarrier 48 carries a rearwardly extending pin for appear. @ne is connected to a 54 on thedog carrier 48. the opposite end'of this spring beingconnected to a pin 55 which extends rearwardly from the carrier 56 of the dog 43. The power of this spring end of a contractile spring therefore is exerted on both dogs and tends*` to return them to normal position. ,From

' an inspection of Figs. 2 and 6 itwillbe obin the nature of a lever of the'l purposes which will hereinafter y rearwardly extending pin g' which the served that thedog rocker is formed with two shoulders 57 and 58 between which the carrier 56 of the feed 'dog 43 is received, these shoulders or abutments limiting the movement of the carrier 56`to and from 7( normal position. It will be understood that the feed dog 43 constitutes a stepping dog which has a movement around its pivot 46 in the general direction of the length of the feed rack 41; It will also be seen that 7i the feed dog 4'2- is fixed against movement in the direction of the length of the feed rack, thus constituting a holding dog, but that saidI dog has a movement aroundv its pivot 45 substantially at right angles to the length of the feed rackin order to move into and out of engagementwith the teeth of the latter. The force of the spring 53 is exerted to normally maintain the carrierof thefeed dog 43against the abutment 57, as indicated in.Fig. 5, and also to normally maintain the feed dog 43 up lin engagement with the feed rack, as shownkin said figure.

, Thedog rocker 47 is provided with trunnion-likepivots 59 and 60, the pivot 59 being received rin a bearing opening in an ear 61 of a bracket 62 which is secured by screws 63 to the shift rail 25. From an inspection of Fig. 5 it will be seen that the trunnion-like pivot of the dogrockler is received in the recessed end of a screwr 64, which latter is threaded into a tapped/opening in an ear 65, corresponding to the ear 61 and like itprojecting `fromthe bracket 62. A lock' nutv 66 is threadedl onto the screw 64 to hold it against accidental vdisplacement `from the position to which it isv adjusted. The dog rocker has a depending projection or arm 67 to which one end'fof a` contractile f spring 68 is connected, theoppOSite end of being connected to adepending said spring arm 69 on the bracket 62.'` The power o this spring is exerted to normally maintain the dog rocker in the position shown in Fig. 1. with the holding dog 42 in engagement with the feed rack. From the foregoing description it will be understood that the dog rocker is carried b v the shiftrail and shifts with the latter during itscase. shifting move- Motion is-transmitted to the 4dog rocker A universal bar 70, which is segmental in form. is arranged above the tvpe bars inthe rear of the pivots thereof. This universal bar is 4bent at lits forward edge, as indicated at 71. to form a contact face with -forward edges of the type bars. near the heels thereof, contact vduring the movements of the type bars tothe printing position. 'l` he universal bar has rearwardly extendinglugs T2 towhich are riveted.` at 73. bracket-like supporting `members 74 which are pivoted'f, at Tftonpward'ly extending parallel supporting arms 76 and "17.v `The lower-.ends of arms'arepro- 'in tearing ripening-fa' the-2 ien" er e bracket, the klatter' being' secured by screws 84' toltheftype bargsegment 3. The opposite4 end l,of the shaft y80'` isreduced to form a l, pivot .85 .whichfis seated-in recessed end of.

ya screw 86 threaded .into a tapped opening in anfear87'on the bracket 83. A lock nut' 88 is threaded onto the screw 86 in order to hold it against accidental displacement from `the4 position 'to which it is adjusted.

Connected with the ,universal bar about midway in the length thereof is a rearwardly. directed .plate-like arm 89 provided with a foot-piece 90 vby which the arm may befriveted,pat 91, to the universaly bar. This arm. is enlarged -to form a vertically disposed plate-like vactuating member 92. A centrallydisp'osed upright supporting link 93 is pivoted vat its upper end, as at 94, to vthe j actuating member and is pivoted at its lower end, as at 95, to an ear 96 on the bracket 88. Thisl link 93 Vwithy the `parallel supporting arms 76 and 77 constitute means for supporting the universal bar and the actuating plate 92, ixedly connected therewith, on the frame of the machine and for movement. fore and aft of the machine. The rear edge ofthe plate-like actuating member consti-4 tutes' contact faces 97--98 which are adapted to coperate with 'the .dog rocker to actuate Figs'. 1 and '5.,

it;l Thus a depending 'arm 99 on the dog rocker. is lprovided with an offset engaging member 100 which extends intothe path of the actuating member 92, as .indicated in During a rearward movement ot the universal bar the actuating member 92 willbe brought into contact with the engaging portion-'100 of the dog rocker in" order to turn said dog rocker on its pivots, irrespective of the position to which the dog rocker may be vshifted with the shift rail.` It will be seen that the contact face 98 on the actuating member extends rearwardly further than the' contact face 97. This is in forder that the actuating member ma)T properljf'coperate with the dog rocker when the platen is shiftedto its uppermost position, 1t

, being understood that the platen and the dog rockerwhich moves therewith receive an upward and rearward movement from the lowermost to the uppermost position.

` In order to limit the return movement of the dog rocker' around its pivot, I have provided a set screw Aor adjustable stop 101 which is received in a tapped. opening 1n the depending arm 99 andeXtends through said opening and is adapted to contact at its torniger and 5).

nan angular stop 102 (see .The stop 102 projects from an ear 103 'carried bv a depending arm or plate-like portion 104 of the bracket 62 ward 'end with which, as he'reiiibeforezl explained, is carried (not shown). This actuating lever 105 is provided with a trunnion-like pivot 106 which is iXed thereto-and ,is reduced at one end to form-a pivot 107. The pivot 107 is received in the recessed end of abearing screw 108 threaded into a tapped opening in an ear 109, which corresponds to the ear 103 and like it projects from 'the bracket plate 104. The opposite end of the trunnion-like portion 106 is reduced at 110 to forma pivot which is received in abearing opening in the ear 108. A contractile spring 111 is connected at its lower end toa bracket arm 112,

secured lby a screw 113 to the bracket plate 104. The opposite end of the spring isconnected to a pin 114 which projects from the trunnion 106. The power of this spring is exerted to return the lever and the parts connected therewith, including the actua-ting member 92 and the universal bar 7 0` to normal position. Operative connection between this lever and the actuating member 92 is effected bv a pin 115 which projects laterali;7 from thelever 105 and extends into a curved slot 116 provided in a depending arm 117 on the actuating plate 92. This slot extends upwardly in the plate, corresponding iii contour to the path of movement of. the pin 115 in the movement of the latter during the case shifting movements of the platen. It will be understood that the lever 105 is thus operatively connected with the universal bar to be actuated by the 'latter atv each printing operation, the movement of the universal bar eiiecting a pivotal movement of the lever toA actuate the ribbon vibrator and ribbon Afeed mechanism (not shown) controlled thereby. It will also be understood that the lever-.105 partakes of the shifting movement 'of the platen in the case shifting movements of the v latter and at such time moves independentl)r i of the actuating member 92.

In order to effect a release of the carriage from control ofthe escapement mechanism, I have provided a releasing bar 118 which extends throughout. or substantially throughout. the length of the carriage and is fixed at `its ends in supporting arms 119, 120. The arm 119'is pivoted on a headed pivot yscrew 121 received at its threaded .end

in a tapped opening inthe ri ht-hand end plate 18 of thecarriage, a was er'122 being interposed between vthe' larm and said end plate. Thearm'120 is pivotally sup orted in a like mannerto 'theright-hand en plate 18 of the carriage. .A11-Thus a headed pivot screw 123 ,is received at its threaded endv in the left-hand end plate 18 of the carriage vand a spacing sleeve 1221 is interposed between the arm 20 and said end plate. The

arm is extended' forwardly and up-l wardly wherefits provided with a finger piece 125 by which .the releasing rod or bail 118 may be controlled. A contractile sprin 126 is connected-at one end to a pin 12% which projects from the arm 120, the oppo# `site end of said' spring being .connected to a pin 128 which projects from the left-hand end plate 18 of the carriage. The 'power of this spring is exerted vto return the releasing bar to normal position. From an inspection of Fig. 1 Vitfwill be understood-that the releasingbar 118 is arranged above the pin 52 .on the dog carrier 18. -A depression 'of the finger piece` 125 is eective thereforeto move the bar 118 downwardly against the pin 52, thereby turning. the carrier 48 on its pivot 45 -to the position vrepresented in Fig. 4. This movement disengages the holding dog 4:2 from-the feed rack in .order to.'

lfree .the carriage from the control of its escapement mechanism and enable the carri-age to be moved in -either direction;

I have provided independent means for controlling the escapement mechanism `from the space `key of the machine. VThus from an inspection o' Figs. 7 and.8 it will be seen that a space key or bar 129 has a sheet metal bracket 130 secured thereto by screws 131. IThis bracket has dependingears or lugs l132 to which a yoke-'like member, designatedvas a whole by the reference numeral 133, is secured by screws 134. This yoke-like member 133 is provided with widely separated arms 135 by which it isattached to the ears 132 and a centrally disposed-depending arm 136 projects from the cross bar ofthe yokelike member. Each arm l135 has an ear 137 'O'ted at 139.l The width of this 1in-k Cerresponds substantially to the width of the yoke-like member 133 `at thelbroadest porthe latter. The rear. end of the link A 138 is pivoted at 140in upright ears 1451 of a bracket112, the latter being securedto a the spring'l 53;v

The rear end o f-therock shaft ,148 has acrank arm 150 secured thereto. This crank arm, as will be best-understoc'xl .from an inspectionA of Figssl' and .5; overlies a' crank arm'1'51 [whichwproject's from 90 will be understood,I therefore, that a depres sion of the space key 129 i'se'ectiveto turn the rock shaft 14:8 and vto 'communicate movementc through .the crank arms 150 and 151 to the .universal bar and the parts controlled thereby tol effect a'letter feed move-. mentof the. t,:a`rriage. l

In the operation of hemachine a depression of thefinger key 15 is effective to actuate the universal bar and transmit movement to the actuating lmember This in turn operates o n the dog rocker to effect a.` pivotal movement of the vlatter. A depression of the finger key is'eifective, therefore, to move the holding dogoutfof engagement' io with the. tooth of the feed rack and to bring the alined stepping dog into en agement: with the same tooth. The power o i the car-v l riage spring-exerted through the feed rack 'l on theI engaged stepping dog ,will overcome' and vthe dog rocker willbe returned to 'normal position by its sprinl y68.

that the `actuatin'g, member 92V 'moves mechanism is not actuated until just before the typebarreaches the printing position when the letoi'of thecarriage occurs, thus providing a rapid f reverse feed and. providing" a light. touch by reason of the fact that each type action is set in motion before any resistance is oiered'by the universal bar or by the escapement mechanism which it controls, ,and that these-parts are taken up successively and not until late in the printing movement of thetype bar. Moreover, while'most of the part.; are' made of sheet metal andare comparatively light and inexpensive to manufacture, 'they are durable and eiiicient in action and are not liable to become deranged or broken.

While I have shown with considerable detail one form' of mechanism embodying -my invention, it should be understood that various changes may be made Without departing from the spirit and scope of the in' vention and that some. parts .may be employed without others.

That I claim as new and desire to secure by Letters Patent, is l L'In typewriting machine, the combi nation'of a carriage; a series of type bars; a segmental luniversal bar actuated thereby; escapement -mechanism controlled by said universal bar;- a space key; a rock shaft which extends fore and aft of the machine andl which is controlled 'by said space key; and intermediate operative connections be.- tween said rock shaftand said universal bar, said intermediate operative connections comprising a supporting arm on which the universal bar is mounted, alcrank arm on said supporting arm, and a coperatin crank arm on the rock shaft. v
