1'0 all whom, it may concern:

Be it known that 1, CHARLES 'Bivori'r, a citizen of the Republic of France, residing Paris, in said Republic, have invented certain new and'useful Improvements in-Stenor graphing-Machines, of Whichthe following is a specification.

This invention relates to typewriters of the class designed to imprint stenographic characters upon a band of paper which is fed longitudinally to the printing mechanism,

lateral feed of such paper.,

One object of the invention is to provide improved mechanism actuated by the depression of the keys for feeding the paper, feeding the inking-ribbon, and up the paper after the same has been written upon.

A further object of the invention is to provide an improved arrangement of the ribbonspools with regard to the ma azine paper-- drum and the receiving-drum tor the paper.

Other objects of the invention are to provide improved means for changing'the direction of the ribbon feed, and to furnish an improved carriage-shifting 'mechanism.

7 To these ends the invention consists in a stenographic machine embodying the novel arts and combinations of the same to be hereinafter described and recited in the appended claims.

In the accompanying drawin s, in Which the same parts are denoted by t e same reference characters throughout the different views, Figure 1 is a side elevation, partlyin section, of a machine constructed in accordance with the invention, Fig. 2 is a detail plan view of part of the mechanism, Fig. 3is a bottom plan view of the machine, showing the carriage-shifting mechanism, and Fig. 4

. illustrates a device 'upon'which the printed each key being. mo

paper band is wound in such a manner that. the characters may be read oii in their proper sequence.

Referring to the drawin s, a indicates the base of the machine, and an upwardly-extending support carried by a box 0 screwed to the base at'the rear of the same. Said support 3) has journaled at the rear thereof a horizontal magazine pa er-cylinder or drum d,.and at'the front,- a orizontal receiving drum e upon which the paper is to be Wound after having been written upon. 2 denotes the platen. The kevhoard comprises keys f,

two. parallel rows,

preferably arrange ted at the forward exend to a. shaft h extending longitudinally to the machine and forming a common pivot for all of the key-levers.

The horizontal rearward prolon ation g of each key-lever, g is operable to liit a horizontal cross-bar 'i which extends across all the key-levers adjacent their upper edges, as shown. Said prolongation or extension g comprises. an upwardly-extending arm or lug g the 11 per end of which enters a rabbet of the typeevers of a carriage m located at the rear of the base, the connection between said end and the corresponding type-lever being constant. All of the type-levers are pivotedto a shaft Z extending longitudinally to the carriagem near the upper part thereof, and each such lever carries at its printing end several types or characters. Fig. 1 shows'one of the type-levers provided with two types 7c, 7r; it is obvious, however, that they may carry three or more of such types. The carriage m is shiftable forwardly and rearwardly on the base a by means of adsvice comprising two shift-keys n, a arranged at the front of the keyboard. These keys are arranged to act upon

levers

0, 0 respectively, these two levers being pivoted at p to the base a, and hidden, ,for the most part, by the latter. The carriage m carries upon its bottom portion depending parallel lugs 7" which extend through an opening 1'"in the base. Between said lugs is secured one end of a connecting rod or bar g, the opposite end 'of which is pivoted to a depending leg of the key a In lever 0, whereby the depression of the effects the rearward shift of the carriage. the rear of

thelevers

0, 0 is a bar 8, pivoted intermediately between its ends and having its ends abutting against the corresponding shift-levers. When one shift-key is imressed the other end of against the other raised and the carriage shifted forwardly,

' key a and lever o are depressed, thecharacters shift-key nis the arm 0, the lever 0 rises as a resultoi'the movement of the bar 8, and in'rising the carriage is shifted forwardly through the intermediary oi the connecting rod g, so that the characters. k are situated at point. The magazine-drum o3 drum e are located at the and the receiving.- rear-and front, re-

- are effected simultaneously when one of theward direction; ward end an upwardly-disposed pawl 'v,which (in which figure the course of the paper is likewise indicated), the paper and inkingribbon being fed parallel to each other.

The winding of the paper upon the receiving-drum e, the feed of the paper, and the progressive movement of the inking-ribbon,

keys is depressed, by mechanism which will now be described.

The upwardly-swinging horizontal bar 5, which is pivoted at i, and which rises upon the depression of one key or of several to gether, carries a laterally-extending pin it (Figs. 1 and 2) which acts, at each ascent, to lift a lever u, pivoted atthe rear of the machine, as shown at a, and extending in for- This lever carries at its forat each oscillation of said-lever produces the advance, to the extent of one tooth, of a ratchet-wheel as, which transmits this movement, by the intermediary of two pinions 'y,

z, to a rubber-covered roller 1 bearing against thereoeiving-dmm e and-imparting to the same its rotary movement, thereby producing the winding of the printed portion of the band of paper upon-said drum.

the step-by-step movement of the platen 2,

i is eiiected by a ratchet-wheel 4, fixed to'the shaft 12 of said platen, said wheel beingengaged by a pawl 5 mounted at the upper end of an arm 3 pivoted at 6 to the base of the machine and actuated by means of a stud 7 upon the lever a. The pawl '8, also mounted upon the arm 3, pawl. I a

The feeding movement of the inking-ribbon in either direction is efiectedby means of a pawl 10 which is mounted directly on the lever u, and which actuates a ratchetwheel 11. To the shaft of said ratchetwheel 11 is keyed a pinion 16, and said pinion is arranged to transmit movement to either of the ribbon-spools 1.3, 14, by means of pinions 15, 15( mounted u on a shiftable hanger 15 on the box a an adapted to engage

pinions

17, 18, respectively, mounted on the ribbon-s 001s. These

pinions

15, 15 mesh constant y with the lnion 16, but when the hanger 15*- is shifte' so that one of is merely a retainingsis-2,2594

the pinions carried thereby transmits rotary movement to its corresponding

pinion

17 or 18 on the ribbon-spool, the corresponding pinion on the hanger is in inoperative position. By shifting the hanger 15 either of the ribbon-spoois may be actuated from the pinion 1-6, and the direction of feed of the inking-ribbon may thus be changed as desired. The hangerlt'i is guidedon the .box 0 by means of astud-shaft 19 movable in a slot 19 in the. side-wall of the box a and carrying a knob 19 by means of which the hanger15 and its pinions are shifted into the desired position.

The type-levers j are returned by leafsprings'20 bearing against the upper edges of the'fsame, and-theparts described as a whole by a single spring 21 acting-upon the lever why the intermediary of alink 22. The tension of the spring 21 may beregulated at will by suitable means such as indicated in Fig. 1. The keys and th eirlevers are returned by helical-springs 24 depending from the front bar 23 of the machine.

Fig. 4 shows in front elevation the drum and winch device which is also shown in side elevation in Fig. 1. This mechanism is fitted to the bar 23 by means of' bifurcated spring lugs 25, and comprises a drum 26 to which a. rotary movement may be transmitted by means of a crank 27.
