In order t`o vsecure accurate alinement, I have found it'dcsirabet/o mount'the clips adj ustably upon the suppQpting-ringand the means vwhich I have illustratedin thcvdra'wings "for, .accomplishing this adjustment consist of locking-screws 36 for the upper clips-extending through radial slots 37`in the type-barfl supporting ring and engaging threaded apar-' Y tnresSS in the said clips, and similar lockingscrews 3l), extending. through longitudinal slots-10 in the lower cli-ps.l and engagingv threaded apertures 41 in the lsupporting-ring.
(For this construction see Figs. 1, El, 4, 7,8, and 9'.) ,y 'Thetype-bars are-,connected with the extremities of the key-levers by 'means l of draw rods or wires 42.
In order to reduce the number ofI type-bars,l zkeys, and operating connections, I employ upper and lowercase shifting mechanism comprising pivotal type heads 43, mounted upon the extremities of the type-hars and'. held in the lower-case position by means of springs 44, as shown in Fig. 3, and as par- 3E "1f-application, Serial No.l 545,508, above mening clips is clearly Aillustrated in Fig, 4,' in` ticularly shown and described in my former tioued.

Y
Dependingfrom the ribbon-spec' spindles' and provided with arms 95, which are fitted 'to slide .upon said spindles, respectively in front and in Vrear of the spools, are the ribbon-guides 06,-having inturned lower exf tremities 07, which extend below the plane of the type-bar-supporting rin',r and beyond the inner edge thereof. These ribbon-guides are flanged outwardly at their front and rear edges, as shown at EN, to form a seat'for the ribbon andy prevent forward and rearwarddisplacement thereof, and the horizontal or inturnedlower portions of the same are pro- .videdwith upstruck 'guiding-ears -99 which engage over guide-strips 100, securedhy i,.eans of brackets 101 to the lower side of the type-bar-supporting ring. The inner extremities ofthe horizontal portions U7 are transversely slotted, as shown at 102, and
through these slots the ribbon 103 passes, saidl ribbonv resting upon the guide-lip 101 at the extremity of the guide. Arranged in thekeyboard is a ribbon-shift key 105, having its stem connected to one arm 106 oa bell-crank level', the lower .arm 107 of said bell-crank lever being connected, by means of a link 108, with one of the ribbon-guides. Said hellcrank lever is lixed to Athe rock-shaft i109, ex-
tending parallel with the line of writing and provided at the end remote from the shiftingkey 105 :with a depending arm 110, connected by a link 111y with kthe contiguous ,ribbonguide. Said ribbon-shifting key is provided ywith a return-spring 112, and by its depression the ribbonguides are simultaneously.
moved to the rear in the direction indicated by the arrow in Fie. 3 to expose the line of writing. f
'In connection with the abovedescribed constructionl employ a table 113, (see Figs. .1, `3, and A12,) provided contiguous to one end and parallel with the edge with ,.a' vertically-adjustablc supporting-strip 114,provided with a depcndingslotted armll, which operates in a-guide-groovell in theguide-blocl5117. `Extending through the slot `118"of said arm isa locking-rod 110, providcdwith ashoulder 120, to bear against.` thc outer surface of the slotted arm and threaded in a nut 1?]` in the guide block. Said locking rod extends through the 'front-bar 122 ol' the table audis provided with y a` hand-wheel `123. In order to raise the supportiiig-strip when released. lby -unscrewing the-locking-red, l employ an elevatin-gspring 124, seated at its lower end in an A`ear 1250i] the guide-block'andcolled porting-strip. ln order to depress the strip to hold the book at the desiredelevatiom'one hand ol' the operator should be placed upon the surface ot' the book, and. when the`dcsired level is reached the locking-rod may be operated to clamp the parts in place.
that the sheet or page to he printed is held in ing plate or platen arranged thereunder and the tracks disposed upon the upper surface el" said sheet or page, the book-supporting strip being adjusted to arrange the page'in a level position, and in order to provide for adjusting either side of the book without changa second supportingstrip provided with means for adjusting the same which are the duplicate of those described in connection with the strip 111.
It will be seen, furthermore, that the tape 12S ol' the carriage-actu ating spring 120, which imparts forward movementvto the carriage and is attached to the carriage-'casing contiguous to its rear side, will not cause twisting or vibration of the carriage,forthe reason that the interval between the carriageguides is small, and'hence the strain of the carriages'pring is direct. Iain enabled to arrange said guides at the minimum distance apart by reason of the disposal of the type-bar-supstructing the same of the c resc'ent'orl segmental shape described and, furthermore, by reason of the fact that the keyboard, keys, and operating connections are disposed Abetween the vertical pla-nes of said front and rear guides. '.-ihe base required for' a carmuch as the center of gravity is contiguous to or slightly below the horizontal piane of the guides.l
A further advantage of the arrangement of the keyboardbetwcen the vertical planes of the guides ,is that vit allows the operator a free view of the line of writing while sitting Furthermore, the key-levers are constructed the type-bars, extend vvertifally downward through a segmental slot..120, (see Fig. 2,) formed in the floorof the Carriage-casing.
In order to prevent the'caiiriage from leaving the guides by accident er otherwiseand. serve as a stop tolimit the 'movement of the earriagevin both directions togthc length of the line which may be printed betweenthe tracks, I employa stop secured to the under side of the type-.bar-supporting ring'at its center and consisting of depending ears 131, the lower extremities of lwhich are disposed below the planes of the upper sides. of the tracks, whereby said ears engagel the tracks and are checked thereby. This Stop, which around a stem 126, depending from the sup' the desired position by means of the printing the'position of the book I provide at 127.

The object in arranging the stop contiguou."- to the printing-point of the carriage and .in the plane of the tracks is that it provides for adjusting the tracks to suit the width of the page without reference to the length of the 'carriageguides whereby the latter may beinadeequal to or greater than the greatest length of line desired. further advantage of this construction resides in the fact that the stop or'the carriage is thus arranged approximately in the plane of the center of gravityor ofthe heaviest portion of the carriag'e', whereby when the 'movement of the carriage is checked the parts thereof, particularly the hangers for the su pporting-riug, are not strained, as would be'the case .witha pendent type-bai'-supporting ring ifthe carriage were checked in or n'ear the planeof the carriage-guides.
In Fig. 13 I have shown slightly-dierent means for securing the adjustable track to the platen, the saine consisting of pins I32, depending from the track and engaging pers forations or sockets 1333 in the platen It will be understood that while L, ha've shou-'nsprings S9 updn the spool-spindles for assisting in returningthe spools ,totheir operative position in contactwith-thc stops 88 I am depending upon the spring 112 to return these parts by making saidspring 112 of sufcientstrength, and in practice I have found the operation of the parts to be satisfactory when relying solelyiiupon the' spring 112, thereby avoiding complications of the oonstruction oontiguoiisto the ribbon-spools.
VIn the drawiugsthe Series of bearing-clips is shown, as occupying slightly less .tia'n a .semicircle', whereby the foremost type-bars strike past the :near horns or arms of the eres# cent-shaped head oftheshifting-bar to cause the engagement of the trip-arm on the typehead withthe far or remote .horn or arm of said crescent-shaped head; but it will be undeistood that inasmuch as the trip-arm inciincs downward below the plane of the lower surface of the type-bar the series of clips may be extended, and the crescent-shaped .head may beI correspondingly extended, as may be found necessary in practice. The type-bars are adapted to strike over the near horn or arm of the head of the shifting-arm to engage the other horn or arm, while the printingface ofthe type-head passes down between the horns or arms. i
AVarious changesv in the form, proportion, and the minor'details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
