Specification of Letters Patent.

I Patented April 2, .1907.

Original application filed February 4, 1901, Serial N0.'45, 810.' Divided and this applicationfiled October 12, 1905. Serial 110,282,493.

To all whom, it may concern.-

Be it known that we, JOHN JAY HANNAHS and ANTHONY A. HIEBER, citizens of the United States, residing at. the city of New York, in the boroughs of Manhattan and Brooklyn, respectively, and State of New 1 York, have invented certain new and useful Improvements in TypeJVriting Machines, of which the following is a full, clear, and exact {'0 description.

' The present invention relates to that classof type-writing machines in which an open per to be inscribed and the type-bars, which are actuated by the keys, strike downward through the frame upon the paper. The type mechanism of this class is shown in our application, Serial N 0. 45,810, filed February 4, 1991, in connection with a fiatplaten, such as is used for writing upon leaves of books or large sheets .of .paper.

The 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 efiect letter-spacing, while the feeding devices upon the carriage serve to shift the paper for line-spacing. Y 1

In the present invention the bed of the machine is provided with a hinge-bar to which the type mechanism is attached to be turned upward, if'desired, also with trackrails'to support the paper-carriage below the type mechanism, and the carriage has upon the to a track-rail which supports the front side 0 the type mechanism by means of a roll resting thereon.

The present divisional applicatiomrelates to the construction of the carriage mechanism'and articularly the apparatus for feeding and ine-spacing the paper thereon.

In the present invention any suitable bed may be used to support the type mechanism above the paper-carriage and any species of rails or guldes maybe used to support such carriage for longitudinal movement.

In thedrawings a machine is represented with a substantially fiat bed provided with track-rails to support the paper-carriage by ,means of rolls upon the carriage and the type mechanism is sustained above the carriage by the connection of its base-frame with a hinge-bar at the rear side of the bed and by a roller upon the base-frame resting upon a rail provided for the purpose on the 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 transverse sectional view through the carriage and other operative parts of the machine, showing the radiating row of type-bars on one side of the machine. Fig. 2 isa top plan view of the carriage. Fig. 3 is a detail side view of the same. Fig. 4 is a similar view looking from the opposite side of the machine. Fig. 5 is a detail view showing the gears forming part of the paper-feed. ing mechanism. Figs. 6 and 7 show other details of the carriage relating to the letterfeeding thereof, and Fig. 8 is a detail view showing a portion of the paper-feeding mechanism by which the same serves to line-space the paper.

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-frame of the type mechanism, having type-bars E with heads E, carrying multiple type-faces arranged in rows radiating from op osite sides of the ed in our applicasupport a roll I), pivoted upon the front of 'the base-frame D. The 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 trackrails G G. I I

A revoluble polygonal platen K is ournaled in the carriage along the middle lineknob. K where 3, 4,) depressiblo by lever Qf limit-springs, V

d are extendek l'from the ragzk-bar M and the rail 0 toward ihefl-tops of. the feedmgwolls,

- and pressure-rolls e are journaled upon the ends of such springs, so as to turn when the feeding-rolls are rotated.

, Flat plates f and-f arefixed in the 'ear{ riage at the outer sides of the rolls L, one-of. them to guide the paper ginto the feeding,

rolls and the other't'o lead the paper therefrom, as indicated by the dotted line g in Mg; 1.

5, the feeding-rolls are connected by gears Z and Z with a central gear 1, having attached to its hubf (on the outer side of the carriage-bar J a ratchet-wheel h, and a line-feed lever N ispivoted upon the same end of the carriage and connected with an arm n, carrying a pawl n ratchet-wheel h.

Aspring N presses the arm and the pawl normallydownward as far as permitted by anadjustable stop t, which is journaled'upon the axleof the ratchet-wheel h, and may be set in diflerent positions] around said wheel by asprin'g-stud j, fitted to any one of a series of holes is in the frame-bar J. A spring n is, provided to press thepawl n normally into;

the wheel h; but the lower end of the pawl is formedwith a shoulder which when it contacts with thestop 'i (seeligs. and 8) throws it out ofthe teeth upon said wheel, so that the feeding-rolls: may be rotated manually by a knob It. (Shown in Fig. 2.) I

The rack-bar is engaged bythe usual feed pinion m, F igs I, 6-, andS, which is provided with the usual escapementswheel m having connections gate the spacing-key F? and the At the righthandend of the paperf carriage; the inside of'which is shown in. l is.

to engage the ,usual connections to the type-keys the letters when printed.

WV hat We claim is I 1; In a type-writing machine, a bed having a hinge bar, a type mechanism supported by said hinge-bar, and arranged to'strike to s p ace downwardtoward the printing-point, a ear riage movable on said bed, a platen joul naled n said carriage, a pair of feeding-rolls adjacent to saidplaten and having their top surhures, in. horizontal alinement with the- .r surface oi'said platen, and gear con: ens between said platen and feeding- 2. In a type-Writing n'iachinc, a bed havinn; a hingeebar, a type mechanism supported by said bar, aparriage movable on said bed, a platen journaled in the carriage and hav, ing a plurality of plane faces in the path of said typemechanism, feeding-rolls adjacent to said platen and having their topsurfaces in. horizontal alinementf therewith, and spring-impelled presser rolls bearing upon saidfeed-rolls.

3. Ina typeswriting machine, a bed having a hinge bar, a type mechanism supported by said hinge-bar, a. carriage movable on said bed, a'platen journaled'in the carriage and in the patlrofsaid type mechanism, said platen having-a ratchet-wheelthereon, a segmentgear carryin apawl adapted to inove said ratchet-whee ,and a cam actuated when the type mechanism ist-ilted about said hinge-' bar for releasing said pawl;

' I4. .Ina type-writing, machine, a pair of' horizontally.- di'spo'sed feed-rolls, pressure gear-section meshingwith said first-named gear-section.

In-witness whereof we subscrlbe-our signatures in the presence of two witnesses.
