'TYPE-WRITING MACHINE.

Specicaton of Letters Patent. Patented Aug. 31, 1915. p

l Application filed January 7, 1914. Serial N0. 810,712.

T0 all lwhom t may concern Be it known-that I, FRANK C. URSBRUCK, a citizen of the United States, residing in New York city, in. the county of New York and State of New York, have invented-certain new and useful Improvements in Typel-Vritilg Hachines, of which the following is a specification.

This invention relates to typewriting .inachines, and particularly to means for enabling-the use of a plurality of sets of typee bars in which the types or characters of one set are of a diierent width' or size from those of the other-'set and require letterspaces on the work-sheet of greater width for the characters ot' one set than for those ot' the other set.

This invention relates principally to machines of the kind disclosed in an application of Stephen T. Smith, Serial Number 802,337, filed November 22, 1913, in which a paper carriage may be translatable from one set of types to. another set, each set having its own keys. The type sets may be placed side by side, and the carriage may run upon a multiple-length track which enables it to coperate with either set of types at the will of the operator. Thus the number of types for use with a single paper carriage niav be doubled, and in order to permit the use of larger types with one set, or

characters requiring wider space on the work-sheet than required by the characters of the other set,Y the invention provides means whereby the paper carriage, when cooperating with one set oi types, is lied through letter-space distances of greater eX- tent than when cooperating with the Aother set. Thus larger types may be used ywith yone set than with the other, or the wider type blocks may be devoted to italics or script, or. the two keyboards could be deetc., or various other combinations 'nay be used. A

This invention also gives the operator the choice of writing letters, bills or other' typewriters, two separate machines Wouldbe required. Also different styles of t pe might obviously be employed on the di erent sets of type-bars.

The present invention is also of value in adapting one machine for writing a number of different .languages where the characters of one language require a wider space than the characters of another language. Thus, for example, the larger types might be used for writing a language such as the Korean language in which a numberof characters are grouped together and printed by a single type-stroke, such a group requiring a wider space than the individual characters of another language, such as English, which could comprise the smaller types.

In the preferred manner of carrying out the invention, there may be employed tWo Underwood front strike machines, which may be placed sidev by side and iXed together, therusual carriage tracks being replaced by multiple-length front and rear rails. anda single carriage may be run on of two keyboards, as more than two key- 'boards and two sets of types might obvioushY be employed.

The carriage track may be` of sufficient length to permit the carriage to be shifted along the rails into'coperative relation with the desired set of types, each set of types being provided with its own keyboard.V The letter-space feed of the carriage, when cooperating with any set of type keys, is coni trol-led by an'escapement rack on the carriage running in mesh with an escapement pinion mounted upon the machine frame. In accordance with the present invention, and .to permit the feed to-be varied for the different sets of type, a plurality of' feed racks are provided upon the carriage, a

' respectively.

y riage rail 5 separate rack and letter feed mechanism belng employed for each setof types, said mechanisms being so proportioned that the letter spacings correspond with the size of type employed in thecorresponding set.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective plan view ot' one form of machine made in accordance with thel present invention. Figs. 2 and 3 are detail views of the escapement mechanism at the lefthandand right-hand sides of the machine, Fig. 4 is a rear perspective view of the mechanism shown in Fig. 2, the escapement wheel being omitted. Fig. 5 is a sectional elevation tak'enabout centrally of the right-hand main portion ofthe machine, as shown in Fig. 1. Figs. 6 and 7 are views of types ot' diti'erent-sizes for use at the left-hand and right-hand sides ofthe machine, respectively.

In practising the invention in the form illustrated, the frameworks 1 and 2 of two Underwood front-strike typewriting machines may be rigidly secured by fasteners 3 5) upon a common base Jr, and they may also be rigidly joined by a rear carand a front carriage rail G, each of which rails extends from the left-hand end ofthe frame 1 to the-right-hand end of the frame 2. Upon these rails may travel a carriage 7, which, as shown, is an Underwood typewriter carriage of the usual con- Structon.` This carriage 'has front rolls 8 which run in the groove of the rail or track 6, and collars '9 which rail 5 I The carriage is preferably provided with a-plurality of feed racks, one for each set of type-bars 12 and 13; these racks 10 and 11 being adapted to be brought into mesh with pinions 14 and 15 mounted upon the 'rightdiandand left-hand frames 2 and' 1,

respectively. The feed racks 10 and 11 may be connected together and form part of a swinging frame 16 pivoted on the carriage 7 and operable by a key"17 to lift theracks 4and thus release either rack "from its pinion.

The pinion 14 may be connected in the usual 'manner through a one-way driving pawl 18 toan escapement wheel 2O controlled by a dog rocker 21, the latter actuated by type keys 22 mounted on levers 23 connected through sub-levers 24 to typefbars12, which have heels,"25 to thrust backwardly a uni# versal bar 26 mounted on links 27 and adapted tostrike the dog rocker 21. The type keys 28 connected tothe type-bars 13 operate 4in like manner through auniversal bar and a'dog rocker 21a to control an escapementr wheel 29.

Assuming the carriage 7 vis in the righthand Writing'field, as' shown in Fig. l, the

operator l-nianipulates thel keys 22 to swing` engage the rear guide therewith, the rack the type-bars 12 upwardly 'and 'rearwardly to bring the types El() thereon against the front face cf the `platen 31,. and the carriage is fed along, step-bv-step in the usual manner, the rack 1U heilig in mesh with the pinion l1 and perniitting the carriage t0 move forwardly at each type stroke a distance detcrn'iined by the pitch of the teeth on cscalnmeut wheel 2i), andthe diameter of the pinion 1i, such distance ably the distance between adjacent teeth of the rack 10. Ribbons ffl-2 mounted on' spools 33 operate in the usual manner.

An index pointer 34 on the carriage moves over a scale 5&5 on the front rail (i: the gradua'tious on the spond with the the carriage wheel 20.

lt' at any time, the operator wishesto use the set of types 36 in the left-hand system, he depresses the release'key 17 to vlift the rack l0 free from thev pinion 14, and then shift-s the carriage to the left to bring the work-sheet ,to the writing position fol,` `the types fltj The key'l7 is then released and permits the rack l1 to drop into mesh with the pin-ion 17 (Fig. lVriting may then' proceed in the usual manner. the keys 2S being n'ianipulated to actuate the types 36.

lly comparing Figs. 2 and 3,it will be observed that the rack l0 can only mesh with the pinion 14, and also that the rack 11 can only be brought into mesh with the pinion 15. TheV rack l() being somewhat lower than the rack 11, holds the latter away from the 'pinion 14, and the pinion 15 being located forward of the rack 10 and out of alinement 1l is permitted to move downwardto engage the' pinion 15.

letter-space movenieuts of being prefer-v scale being spaced to corre as controlled by the eseapement A As indicated on the drawings,the diameter ofthe pinionv 15 meshing with therack 11, is greater than that of the pinion 14 on which runs the rack 10, thus providing for feed of the carriage through comparatively wide letter-space.distances when in -the zone of the types 3G. The same result might be obtained in other ways, as forA example,.by having the teeth on ,the two escapernent wheels 20 and 29 'of different pitch.l These letter-spaees may, for example, be in the ratio of 8 1:0.10, as indicated by the

scales

35 and 37, the graduationsof which are spaced to correspond with the letter feed movements of the carriagewhen controlled throughthe racks 10 and 11, respectively.

, Obviously the ratio, as well as the'absolute value of the letter-space distances might be varied, or the positions' of escapement mech- Aanisms interchanged.

with upper and lower case types either of which may be called into use by a shift key 40, and the type-bars 12, as indicated in Fig. 7, are also provided with upper and lower'case types either of which may be called into use by the operation of a shift key 41. Thus on a single piece of work all of the different types may be employed.

AThe shiftkeys 40 and 41 are for temporar-y use, each being held depressed 'while the type keys are manipulated. The keyboards are also provided with permanent or locking shift keys 42 and 43. which lock the platen 3l in the upper shift position. The shift keys are connected to the shift rail 44 through suitable mechanism comprising a shift frame 45, whereby when a shift key is depressed, the rail 44is lifted and through l a shift roli 460m the' platen frame lifts lthe platen frame and platen to the upper shift position.

At the right-hand end of the frame` 2 the usual adjustable margin gage 47 for limiting the return stroke of the carriage in determining the beginning of a new line. The usual left-hand margin gage is omitted from the frame 2 in order to permit the shifting of the carriage across to the frame 1, and the usual right-hand margin gage is omitted from the frame 1 for the same reason. Fig. l, however, carries the usual adjustable let-hand'margin gage 48. Each keyboard is also provided with a space key, said keys shown at 49 and 50, and in general each section of the machine'` cooperating with the carriage forms a complete typewriter of itself.

Varia-tions may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I
