TYPE-WRIT|NG MACHINE.

SPECIFICATIQN forming part of Letters Patent No. 344,143, dated June 22, Il B86.

Application tiled September 22, 1885. Serial No. 177,810. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CHARLES Srino, a citizen of the United States, residing at New York, in the county of New York and State Vo f New York, have invented certain new and useful, Improvements in Type Vvriters, of which the following is a specification, reference being had to the accompanying draw-A ings.

This invention has relation to that class of typewriting machines which comprise a disk having printing-characters at or near its periphery and mounted for rotation to bring a desired character to the printingtield,toward which the disk is actuated by hand to give an impression of the character selected. The motion of the parts employed in giving the impressions has also been utilized in feeding the platen or paper-carrier to present a new printing-field for succeeding characters.

The object of my invention is to produce a machine consisting of as few parts as possible, and yet possessing the essential characteristics and capabilities of machines having a greater number of parts, so that a practical useful type-Writer having substantial merit can be secured at a low cost.

In order to accomplish the object of my invention, I have peculiarly constructed and arranged the principal elements of the machine, as hereinafter described, the novel features being particularly set forth in the claims.

Referring to the drawings,Figure l is a plan of a type-writing machine constructed in accordance with my invention, one end of the machine being broken off. Fig. 2 is a plan of the under side of the principal elements in volved in the printing, inking, and feeding mechanisms of the machine. Fig. 3 is a side elevation of the printing, feeding, and inking mechanisms, the remaining portions of the machine being shown in vertical section. Fig. 4 is a side elevation of the bracket and dial. Fig. 5 is a plan and side elevation of the inking mechanism. Fig. 6 is a plan of the principal lever of the feeding mechanism; and Fig. 7 is a side elevation of a simplified bracket.

Like letters indicate like parts in all the gures.

The object of the invention being, as before stated, simplicity, eheapness, scrviceability, and the possession of the substantial merits of higher-priced machines, I make material progress toward that object Iby constructing the framework of the machine in a single casting comprising the bed A, end brackets, A', and tie-bars A2 A3. If desired, (and it may be preferable,) the tie-bars A2 A3 maybe of separate pieces, bars, or rods secured to or in the brackets in any suitable manner. A platen, B, having pawl and ratchet line-spacing mechanism B and thumb-nut B2, is mounted in the brackets and partially encircled by a guide plate, B3, these parts being for the reception and feeding of the paper, as usual. A guiderod, C, having ahandle, C', is passed through the brackets, and serves to hold the paper X upon the platen. Between the tie-bars is arranged a feed rack-bar, D, which is mounted pivotally by means of screws D', threaded in the brackets and projecting into the ends of the rackbar. A projection, D2, on the rackbar,by coming into contact with a similar pro1 jection, D, on the bracket, limits the oscillation of the bar in one direction. Upon the rack-bar is mounted a bracket, E, having a sleeve, E', perforated to embrace the rack-bar, the perforation being in this instance rectan4 gular, as is the rack-bar,in cross-section. Other forms of perforations and rack-bars may be employed, either polygonal in cross-scction or circular, with a groove or iin co-operating with a fin or groove in the sleeve.

Projecting from the bracket is a post, E,

and at the opposite end of the bracket a hub,

E2, is formed, upon which, in one instance, is mounted the dial E, while in the other instance (see Fig. 7) the bracket itself is constructed as a disk or dial, E, the hub E2 being arranged on the under side thereof.

At one end of the bracket and above the rack-bar is arranged the feeding mechanism, which comprises a lever, F, pivoted at F', and extended to form a check-pawl, F", which, by means of a spring, F3, secured at one end to the stud E", is forced into contact with the rack`bar. To the lever F is pivotally secured the feed-pawl G, which, by means of the spring G', is forced into contact with the rack-bar when not otherwise infiuenced. The spring F3 heilig wide, bears upon a pin, F4, projecting IOO from the check-pawl F2'. It is evident that the spring may project upon the check-pawl, thus obviating the use of the pin.

The printing device is a disk, H, having a depending flange, II, on the lower edge of which are arranged the printing-characters, the disk being secured to the locking-wheel I by screws H2, therefore permitting of the substitution of different printing-characters. The locking-wheel I is acted upon by the usual spring-detent, I', (see Fig. 3,) secured to the under surface of the bracket and projecting between the teeth of the locking-wheel, as usual. The locking-lever I, having the detent I, is pivoted at IJX to the bracket below the sleeve. Projecting downwardly from the lever :I2 is an arm or rod, F, to which 1s secured an inker-operating arm, L, which 1s b1- furcated at its end; or it may be other-wisel adapted to be pivotally connected with the arm M, projecting from the pivoted end of the inking-arm M, which is rotatably secured by the screw N.

The inking-padO is mounted on the padcarrier P, pivoted to the free end ot" the armI M. A spring, P', normally presses upon the carrier upon one side of its pivot, so as to permit the carrier to bedepressed, as shown by dotted lines, for the purpose of applying ink to the pad, and so as to yieldingly hold the pad in-contact with the printing-characters.

A coiled spring, K, is connected with the arm'L, and with the sleeve E', as clearly shown in Fig. 2.

J represents a handle, and J a pointer attached to the usual vertical shaft ofthe print-` ing-disk and locking wheel, whereby these parts may be rotated for the selection and presentation of a desired character at th printing-field of the machine.

F6 represents a handle projecting upwardly from the free end of the check-pawl lever F. From the opposite side of the lever there is a downwardly-projecting rod, F5. The rod IL is adjacent to the tie-bar A3 and the rod F5 is adjacent to the tie-bar A2.

The raclcbar is provided with numbers increasing from left to right, which serve the purpose of determining the point of commencement of a line of printed matter upon the platen.

The inker-operating lever L is mounted upon the rod IAL by means of the setscrew L', so that 'by securing the lever to the rod in different positions the ink-pad may be made to oscillate in contact with printing-characters more or less near the printing field, as desired A stop, Fl, serves to limit the movement of the lever F in one direction.

Thisbeing the'coustruction, the operation is as `follows: The machine in its normal position is clearly shown in Fig. 3, where the printing-disk is sustained in an elevated position above the platen by means of the reaction of thespring F3, bearing upon the check-pawl F2 and against the stud E, so that the free end of the check-pawl lever and its rod F5 is pressed yline of work.

against the tie-bar A2', the stops D Dideter mining the limit of the depression of the upper end of the bracket, aud therefore the elevation of its lower end. By means of the handle .I the pointer J is turned until it indicates a desired character, and force is applied in the desired direction on said handle, so as to depress that end of the bracket at which the handle is located. Such depression causes the rack-bar to oscillate or rock upon its pivots and the rod F5 to bear against the tie-bar A2. The upper end of the bracket moving in a circle the center of which is the center of the rack-bar, the rod F5 causes the handle F6 and the free end of the check-pawl lever, to which it is secured, to move away from the rod A2, by reason of the constant contact of rod F5 with rod A2, the former being bent under the latter, so as to lift the check-pawl F2 out ofconnection with the rack-bar and against 'the pressure of the spring F. This movement of the free end of the lever F draws the pawl G to the right, Fig. l, and upon the sleeve E', and out of connection with the rack-bar, and over a distance of one tooth thereof. By the same depression of the bracket the rod 1*, bearing against the tie-bar A3, causes the lever IIl to move into a position away from the sleeve, and substantially indicated by the dotted line a, Fig. 2. This causes the lever L to take the positionof dotted line b, the arm M to take the position of dotted line c, and the inker arm and pad to take the position indicated by dotted line d, thus removing the pad from over the printing-field, and at the same time distributing ink upon the character to be employed and the characters adjacent thereto. When the power applied to depress the printing-disk is removed, the reaction of the spring F3 upon the check-paw] F'l elevates the bracket to the position shown in Fig. 3, while the spring K, acting upon the arm L, returns the inking mechanism and the lockinglever I2 to their normal positions. When the printingdisk is depressed, the locking-lug I3 enters between the teeth of the locking-wheel to secure a proper alignment o'f the work. A stud, Q, may be secured by a screw or otherwise to the bracket just over the rack-bar sleeve, so that by placing a thumb against the same, and by means of a finger depressing the handle F,the checkpawl lever may be depressed, so as to throw both pawls entirely out of connection with the rack-bar, and thus permit of a movement of the carriage from right to left to begin a new This stud Q may, however, be entirely dispensed with and the thumb be placed against therhandle J, while the inger depresses the handle F, for the purpose described. I therefore illustrate in Fig. 7 the bracket without a stud thereon for the purpose mentioned.

The combination of a frame-work having a tie-bar, a rocking rack-bar parallel with the tie-bar, abracket mounted thereonand carrying a type-disk and a check-pawl lever, the free end i' of which is provided with a depending` rod having contact with said tie-bar, and a pawl spring, substantially as specied.
