To fir/ZZ whom, it may concern;

Be it known that we, J OHN J. HANNAHS, whose residence is 210 West Fourth street, New York, county ot' New York7 and AN- THONY A. HIEBER, whose residence and postoi'lice address is 1243 Putnam avenue, Brooklyn, county of Kings, State of New York, citizens of the United States, have invented certain new and useful Improvements in Type-Writers, `fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

4 The present invention relates to that class of type-writing machines in which an open base-frame is supported upon or over the paper to be .inscribed and the type when actuated by they keys strike` downward through the frameupon the paper. A type mechanism of this class .is shown in our application, Serial No. 45,810, filed February 4, 1901, in connection with a flat platen, such as is used for writing upon leaves of books or large sheets of paper.

lhe chief object of the present invention is to adapt the same type mechanism for-use with a movable carriage carrying line-feed rollers. In. such new construction the type mechanism is held stationary and the carriage travels longitudinally beneath the same to `effect letter-spacing, `while the feeding d evices upon the carriage serve to shift the paper for line-spacing.

ln the present invention the bed of the machine is provided ,with a hinge-bar io which the type mechanism is attached to be turned upward, if desired; also, with track-rails to support the paper-carriage .below the type mechanism, Iand 'the carriage has upon the top a track-railwhicli supports ihefront side of the type mechanism lbymcans of a rolloli-,the supports for the tabulating-stops,

resting thereon.

The present improvements include the construct-ion et the bed withwtrack-rails in the lower part and a paper-carriage movable thereon and a support igor the type' mechanism above such carriage, means to balance the Jtype mechanism when turned upwardly upon t he hingebar, and means for locking the Paper-carriage when the type mechanism is raised I in the present invention any suitable bed 'speeicatin of Letters Patent. l

may be used to support the type mechanism above the paper-carriage, and any species of rails or guides may be used to support.such,

. carriage:

The `construction shown in the drawin `s will first be described, and any desirab e :modifications will then be pointed out.

Figure 1 is a plan of the machine Without tabulator. Fig. 2 is a cross-section on line 2' 2 in. Fig. 1. Fig. 3 shows the base-frame with the ribbonfeed attachments alone,4 Fig. 4 is a plan of the paper-carriage de'- tached lfrom the bed and type mechanism.

' Fig. 5 shows the right-hand end of the pa ercarriage and its connection with the ed. Fig. 6 shows the left-hand end of the apercarriage and the same connection. ig. 7

shows the gearing within the right-hand end of the paper-carriage.. Fig. 8 is an elevation viewed .from within the center of the baseframe of the connections from the spacinglever to the feed-escapement. Fig. 9' is` an elevation of the escapement-lever with the pawl shown in dotted lines. Fig. 10 is an elevation, drawn twice 'the size of Fig. 5 of the line-feed pawl and adjustable stop. Fig. 11 is a plan ofthe tabulating appliances. Fig. 12 is an elevation of the same; Fig. 13,

an end elevation of the bed and carriage withV cross-section of the base-frame, showing the tabulating appliances; and Fig. 14 shows one.

Fig, 15 is a'plan, and Fig. 16 a side elevation,

Vshowing the manner in which the universal bar orbars which are operated by the keylevers are connected to the devices which control the letter feeding or spacing movements ofthe carriage.

A designates the bed of the entire machine, havingat its rear corners bearings B, .projected upwardly to carry the hinge-bar C.

.D 'designates the base-frameof the type IOO mechahism', having type-bars E with heads E, carrying multiple type-faces arranged inl rows radiating from opposite sides of the printing-point, as described in our applicapivoted upon the front oi the base-frame D.

he rear edge of the base-frame has lugs C secured upon the hinge-bar C, and such lugs and the roll'b support the type mechanism in' its operative position above the paper-carriage, which is free to move longitudinally upon the track-rails G G". A revoluble po- A lygonal platen K is journaled in the carriage along the middle vline thereof and is provided at one end with a knob K', whereby it may 'be rotated. The usual notched wheel K2 is `fixed to the platen, and a detent K3 of any usual construction cooperates with said wheel to prevent accidental revolution of the platen. Feeding-rolls L are journaled upon the carriage-bars J at opposite edges of such l platen, and a rack-bar M to feed the carriage for letter-spacing is carried upon the rear edge oi the carriage by pivoted arms m. (See IFigs. 4, 5, and 6.) Leaf-springs l are extended from the rack-bar M and the rail c toward the tops of the feeding-rolls, and pressure-rolls e are journaled upon the ends of such springs, so as to turn when the feedingrol-ls are rotated. Flat plates f and j are fixed in the carriage at the outer sides of the as permitted by an adjustable stop i, which rolls L, one of'them to guide the paper g into the feeding-rolls and the other to lead the paer therefrom, as indicated b y the dotted line g in Fig. 2. At the right-hand end of I the paper-carriage, the inside of which is shown in Fig. 7, the feeding-rolls are connected by l l with a central gear Z', having attached to its hub (on the outer side of the carriage-bar J) a ratchet-wheel fi, and a line-feed lever N is pivoted upon the same end of the carriage and connected with an arm fa, carrying a pawl n to engage the ratchet-wheel 7L. A spring N presses the arm and the pawl normally downward as far is journaled upon the axle "of the ratchetwheel 712 and may be set in different positions around "said wheel by a spring-stud, iitted to any one of a series of holes lc in the framebar J. A spring n2 is provided to press the pawl n normally into the wheel 7L; but the "lowerend'of-the pawl is Yformed with a shoulder-which when it contacts with the stop i, (see Figs. 5 and 1U) throws it out of the teeth @eaves bein u ou a lover or arm' which is, ivoted v at '22 upon a part of said frame D. T e'lever p and the pawls are vibrated by the 'typelreys. For this purpose there is employed an actuating-arm 23, extending forwardly from a rock-shaft 24, journaled in ears 25, rejecting rearwardly froml said frame By rocking the shaft the arm 25 vibrates and b means of 4its forked connection with paw lever p gives the necessary o'cillation to the latter, so that the paper-carriafe is fed step by step un`der the influence o` the .springdruni M.' Also fixed upon the rock-shaft 24 are two iorwardlyextending arms 'J p, whereby said shaft is rocked. Each oig the type-operating levers 26, bearing the keys F,

is provided with a lug- 27 to'catch under a 95 universal bar 28, one at each side of the machine, Figs. 1 and 2, to lift the universal bar or bars during the movements of the typebars to the platen, Said universal bars are mounted upon arms 29, the latter fixed upon and projecting rearwardly from a rock-shaft 3 By means 'of this universal-bar frame the arms p are rocked, the escapen'ientlpawls 2() 21 operated, and the paper-carriage fed at the successive operations of the typekeys F. lhe outer arms 29 are forked at their rear ends at 29a, Fig. 16,` to engage pins 29h, fixed in the forward ends of arms p, whereby movement of arms 29 is communicated to the latter.

It will be understood that when the typebar-carrying frame D is swung upand back about the hinge .or axis C the escapementpinion m, w'iieh. is mounted upon said frame D, necessarily swings up out of engage- IKO ment with the escapementrack M, and

hence loses control of the same and of the paper-carriage, so that'the latter would be .driven to the `leift by-the sl'iring-drum M; but this dilliculty is avoided by the use of a detent 31, fixed u on said frame D immediately behind rack il and normally out oi' engagement therewith, Fig. 2, but moving into engagement with said rack as said frame' D swings upward, so as to keep control of the rack while pinion m is rising, and thereby hold Itho carriage stationary, said detent curving about the axis C or having the form of a segment. so as to maintain engagement with said rack during the swinging up and When desired the carriage maybe` moved freely to left or right Whether the frame D is up or down. The type-guide a, which is a necessarily adjacent to the1printing-'po1nt upon the platen, serves as a convenient ind ex to' guide the 'operator in positioning the carriage.

' One of the arms m, AWhich supports the rack-bar M, "has a lever ma and'islextended (see Figs. 6 and 1 1) past its'fulcrum (upon ,then

carriage end nearly to the opposite side of the carriage, and a release lever or key Q is pivoted upon the same ien'd of the carriage and has an arm Q extended beneath the end of the lever m3 and supported When at rest upon Vthe pin g. A spring fn'c* presses the arm mupward to hold the rack-bar M normally in engagement with the pinion m', and the carriage is 'released from the pinion m by pressureV upon the release-lever Q, which lpresses the lever m upward and lowers the rack from the pinion. r

Counterbalanc'ing of type mechaisimw Figs. l2 and 13 show a collar 1^ uponthe hinge-bar C adjacent to the bearing B, in Which one end of the hinge-bar is journaled,

,such collar having a segmental noteh'whose opposite ends 1" form stops to engage a pin s upon the bearing. A spiral spring t is wound upon the hinge-bar and has one end attached to such pin and the other end to the hingebar,the torsion of the spring being adjusted to counterbalance the' greater part of the Weight of the type mechanism.. AOne of the stops r serves to hold the type mechan- Ithe spool-shaft 11.

ism when turned up into equilibrium' above the hinge-bar to correct the Writing upon the paper beneath. A sullicient proportion of the Weight is'left unbalanced by the spring t to drive the roll b by friction with the rail c when the carriage is fed by the rack-bar M.

Ribbon-feed.-Figs. 1, 2, and 3 show a shaft u geared to the roll b and carrying a Worm u', fitted to a Worm-Wheel v upon the The 'shaft is fitted -movably to the Worm-Wheel and has a slot c2 to fit a pin or key in the Worm-Wheel, and the shaft may thus be shifted4 endwise to engage the gears es With either spool V at pleasure. The Worm-Wheel is held from end motion by suitable stops, andthe spool-shaft is locked in either of the required longitudinal adjustments by a latch n, fitted at pleasure to l either side'oil a collar v5 upon the spool-shaft.
