Thejstern 40 of each lever 29 i's' pi 'otally connected'to a rearavardly extending link 41 and the rear end of 'saidlink 41 is'pi-ioted -to a-lug 42 of alty'pebar 43, The typ'e bars 43-;are pivoted to a wire or rod 14', arranged .in asegment 45 said segment being held'to the-transversely .100 extending bar,19.' At the"forward end of each type-bar 43; is a block or head 46,011 which are a plurality of characters 47. There may be two or -mor'e chara-ctersifacja machine has-a single ,105 or-don l'e-fcase shift.

The outer type bars are pi'votally held and type-barsgi usually four'in number ateach nected to the lower levers 29, areconnected to levers, Fig. .14, corresponding some- 4 what'to "the shape of the levers 29,. These ted'to' the stems of the m I end key-operated levers, and each of said end key-operat-edlevers is pivoted to a link i or let er 50" thereby providingpairs. of levers in a. manner similar to the remainder of the key-operated levers. .The upper levers 50 are each provided with a projecting. stem rtion 50 which is connected to one of the inks of the type-bars to operate the same,
.' and is provided with aforwardly projecting part 50 to which a spring 50 is vcon-- lnected, said: springs being held to the plate 39 in amanner similar. to the springs 38 and like said springs serve to return the key-operated levers to their normal position. The bar 11 1s cut away to provide free move ment to the projecting part 50 of thelevers 5Q". The purpose of havingthe links of'the end ty bars connected to the upper levers 50, w ile the links of the other type-bars are eonnectedtoithe lower levers, is that a more direct connection is thus made with the brackets 51, Tat-theforward edge by a rail 52 and at the rear portion thereof by'a rail .53. These type-bars anda more uniform touch ob tamed.
The carriage 50 comprisesend plates or. which are ,COIlIlGCfJiCl together 'f1rails aretgrooved, and are opposed to grooves ails 54 .and55 respectively, so as to proy raceways for anti-friction devices, as" ball '6, toadapt the carriage to travel is mounted upona shift. frame 58, said] the tension of i a strap 59 riage, "various means may carriage and shift jecting outwardly adapted to "be engaged readily transversely of the machine under the tension-ofa spring in a drum 57, which drum being provided with means to vary thespring and connected by or. other flexible connection to a rearwardly extending part 60 of one .of the carriage end plates 51 The rails 54; and 55 form a part of the shift frame, and the rail 54 is pivotally mounted by means of 12, orotherwise to lugs 62 3 screws 61, Fig. 0n the movableffame part 12 to adapt the I frame to "be moved with thereon relatively to the the parts mounted by mechanism typesfor case shift purposes, to be presently described.
As a means-to shift the frame be employed. As shown, the 'shiftframe 58 is provided with a roll or a plurality'of rolls 6i, Figs. 5 and llfwhich are held to a stud or pin 65 pro- 4 from one of the side rails The rolls .64 are by shift levers '66 and 67; The two shift levers 66 and 67 are both pivoted to a lug (38 pro ect1ng 1nthe side plate 20 of the mov- '1'2,.and each lever is sub- 63 of "the shift' frame.

Thepart 71 of the'lever (i s longer than the sa'me part of the lever part 71 ofthe' lever 0s is prohill -a d vided with. a cam'slot. 72 at the upper portion thereof, while the lever 67 is provided with a cam slot T3 at the upper portion thereof; and are each adapted to engage one of the rolls 4 on the shift frame, said rolls being s jaced by a suitable washer. The cam slots 72 extend upwardly and rearwardly, while the slot 73 'extends downi wardly and rearward-l), and during the operation of the shift lever 66 will raise the roll and shift frame with the carriage and partsmol-mted thereon from thenormal p'osi" tion shown,.while on the depression of thelever. 67 the cam slot. will cause the shift frame to be lowered from the normaloperativeposit-ion shown. It will be'evident that the cam slot 73' prevents the roller from passing too far down when returnin'gfrom "the upper base position, and the canrslotm of the.leverfilserves not only to shift the roller andshift frame upwardly, but holds it against movement, above its centralpositionwhen returning from the lower shift posit-ion, said'cam slots being made the exact length to move the rollerthe proper dis tance when it is at the extreme end of the cam, and in this way the 'twocam slot-s guard against vibration of the roller and shift frame with the-carriage in all of its,
three positions. The weight of the shift frame andcarriage is nearly ba'lanccd'by a suitable spring Tl," which is secured to the rear bar 23, and the shift levers are returned totheir normal positions as soon as their;
finger keys are released by spring 7-H, said shift. levers being adapted to engage a back stop or rest T Fig. 12, against which the arms are normally held by their retracting springs. The shiftlevers as thus mounted have the keys board, and by having the Slllftlevers mounted upon the movable frame-part 12,
forming a part of the key -the keyboard is thus partly mounted upon a stationary part of the main frame, and
another part-upon the movable part of the main frame.
A universal bar frame 76 having a uniis pivoted to a transversely extending rod 78, The rod 78 is held betweenth'e side plates 20 and 21 of the movable frame part 12, and par takes of its compact movement. 3 The universal bar Wis adapted to be engaged by lugs or projecting portions 79 on each of the key-operated levers 33, 3-l'and'35, so that on the depression of any one of said levers the universal bar will be moved downwardly with, the rod 7 8 as a pivot. A link 80 is 7 at the forward portion thereof pi'votally held at its lower end to each of the rearwardly extending rails ,of the universal bar frame 76 and at the upper-end each link is pivotally connected to the forwardly ex-, I
tending arm of a lever 81. There are two levers 81 one at each side of the machine, and each lever pivoted at.82 to sing or iao' i one direction by a spring 1.
project ion H3. The rear arm 8-1 of each lever H1 extends ]t2ll'\\'2lltll and downwardly and is connected by an integral rod portion H5. On the rod portion is a rearwardly extending arm ht' having an angular portion ST which is adapted to engage the end NH of a dog carrier Ht This dog carrier at). Fig. 13. is loosely pivoted on a pin 90. and is provided with a slot 91 to adapt the same to have a relative movement on its fulcrmn pin 10. The carrier S51 is provided with dogs 92 and 9?, which ale adapted alternately to engage the teeth t l of an eseapement wheel 11.1 said dog carrier being normally t'orced in ()n the stud or pin on". and formed separately or integral with the wheel 1).) is a pinion 9T. \vhieh is adapted to engage a rack US extending len n'thwise of the carriz'ige it) to travel therewith.
When any one of the key-operated levers is depressed the projecting portion or in; TH thereof will engage the universal bar TT and will depress the same. thereby mo ing the links so. levers S1 and rod 85 on the pivots s2 to move the part 8t", upwardly into engagement with the end of the dog carrier. thus releasing the do gpit'rom one of the teeth of the toothed wheel 9.3. As soon as the dog 93 is released the dog 92 is moved into the path of another tooth of the toothed wheel. and prevents the wheel from moving more than the space of one tooth corresponding to a letter space of the carriage. as is usual in escapements of this kind. The purpose of the spring; 96 is to give the dog carrier at) a slight movement by reason of the slot 5 1 to prevent the dog 93 from again engaging the same tooth of the wheel 95. This particular escapement is not specifically claimed herein. having been made a part of a separate application. Serial No. 102,931 filed June 10. 11 16. The escapement mechnism; as well as the tension means. with the exception of the universal bar. is mounted upon the shiftframe, and partakes of the shift movement.
A space bar. 98*. Fig. 1. 5. 12 and 15 is supported by arms 98. These arms 98* are pivoted at their inner ends to brackets on the transversely extending bar 18 and one of said arms or both of them. ifdesired. has a pin 98 which enters a slotin a lever 98 The lever 98 is pivoted to the rod 30. 011 the slotted transversely" extending fulcrum bar 17 and at the outer end is held by a spring 99 similar to the springs 38. The rear end of-thelever 98 is ada )ted to engage and operate the universal ar '77 when the space bar 98 is depressed: thus the universal bar is actuated not onlv by the space bar, but "by the ke v-operated levers.
The carriage has the usual parts 006 we ating therew1th .as for example. paper eed means, ribbon mechanism, etc. These parts plates 51. The paper table on extends about the lower portion of the platen i and at the forward portion thereof is divided and made .to support the ends of the shafts on which three short feed rolls 103 re mounted. these rolls being located at intervals under the front edge of the platen and are normally tort-ed against the platen to engage the work sheet to feed the sheet with the platen when the latter is rotated. ()pposite the spacesbetween the front teed rail is a pair of rear teed rolls 111 The e roll 111;, are mounted on the rear end of heet metal upports 1 whieh have their fr nt portions rigidly con neeted to the upper urface of the rail .371. The supports fol the front t'eed rolls Cross and overlap the edge of the rear roll supports. and by moving the upper edge of the paper table forwardly both front and rear feed rolls arewithdrawn from the platen, it being understood that the supports for both front and rear rolls may be of sheet metalf and of spring temper.
Two ribbon spools I and 1011 are mount ed to rotate on extensions 10? projecti11g-.in= \vardly from the side rails as of the shift rail 5H and partake of the shifting movement of said frame. The ribbon spools are similarly constructed. Each -e 1nprise two sheet metal disks los and 10$). Fig. 1. having a spacing sleeve 111 and an inner sleeve 111. which passes through the disks and has its ends riveted to hold the several parts together. A short flanged tube 112 is mounted (2 a fixed stud 113 and a ratchet wheel 114 rests on the flange end of said'tube 112. a thin spacing washer being; placed on the ratchet wheel to space the spool therefron't. A knurled nut 115 is screwed (into the threaded end of the tube 112 to clamp the. ratchet wheel to the spool. the studs 11 -1 being tixed to the rackets 1t)T. .Eaen atchet" wheel is adapted to be engaged by a' pawl" 11"). each of which has its upper end rigidly secured to one ot the levers R1 and its lower end shaped to act as a drivingpawl on'the ing, to prevent backward movement of" the ratchet wheelI -at all times. Theratchet wheels in operation rotate slowly in opposite directions whenever the machine is in llr-ti and the ratchet wheel of the driving spool must be locked to'its spool by lneans'ofthe nut 115 to cause the spool to rotate'with'its ratchet wheel. the other spool being {loose upon its stud 113. To reverse the. feed of the ribbon the winding spool is'releasedi frdm; its driving ratchet and the. other-w-heelfiofi eted brackcts.--
