['0 al whom it may carioern: Be it known that I, JOHN BECKER, of Boston, county of Shifolk, and StateiofMassaeh'usetts, have invented an Improvement in Type-Writing, Machines, (patented in Great Britain, No. 12,960, dated October 12, 1886 in Germany, No. 41,127,:lated October 13, 1886 in Austria-Ho n gary,No. 9,034and No. 31,660,dated August 19, 1887; in France, No.182,323, dated Mareh21, re 1887, and in Canada, No. 26,157, dated March 7, 1887,) of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to improve the construction of type-writers of the class shown and described in United States Patent No. 350,717, dated October 12, 1886, granted to me.- 2o In accordance with this invention a comb-- like Presser-bar is employed to hold the paper upon the feed-roll. The inking-pads are attached to a sleeve mounted tomove freely Y upon the ratchet-toothed feed-bar in unison .25 with the printing devices, the said. sleeve being cut away at its upper side to permit the feed-dog to engage the teeth'of the ratchettoothed bar to efiect the step-by-step feeding V of the printing devices. The ruhbersegm'ent' o attached to the type-carrying segment pivoted --to the index-plate has upon its under side a series of projecting type separated by deep grooves, in order that as the rubber segment 7 carried by the type-segment is acted upon by the pivoted printi'ng lever each type may operate independent of its neighbor to print upon the paper. The spacing-stop herein shown consists of a spring-arm attached to the end of a -rocking" lever near that portion o thereof which is touched by the hand of the operator wh elrdepressing the said lever, sn ch position-of the. spacing-stops rendering it readily accessible. The bell to indicate the completion of each line is located upon the carriage in position to be struck by a positively moved bell-hammer actuated by the rocking lever.

Figure 1 shows in top View a type-writer em bodyin g this invention; Fig. 2, across-section of Fig. 1, takenonthe dotted lineww; Fig. 3,a rear side view'of a portion of Fig. 1, showing the pivoted printing-lever and the sleevecar- ,rying the independent pads; Fig. 4, a lefthand end view of the machine, the carriage comprising the printingdeviees being omit-t ted ;?Fig. 5, a. detail of the independent pads; Fig/'6, an enlarged detail of a portion of the rubber segment; and Fig. 7, an edge view of Fig. 6, to showfthe deep groovesiu the rubber] segment between the t-yp'es.

The main frame A, feed-roll lo, index-plate B, having'attached guides or arzhs I) mounted to-slide freely upon the ratchet-toothed har I a, the type-carrying segment 0, pivoted at C to theindex plate B, and. having an operat ing-lever c, the rubhersegment 0, attached to the type carrying segment 0, and having upon its under side a series of projectingltype, the series of. holes 4 bored in the type-carry ing segment to receive a pin attached to the printing-lever e, pivoted to the index plate, the feed-dog g.loose1y attached to the printinglever e, and engaging the teeth of the ratchettoothed bar a, the rocking lever 1, extending lengthwise of thefmachine and connected loosely with the ratchet-toothed bar a as its support, are all substantially as in the patent referred to, so need not be herein further described. p The feed-roll a, having its hearings in the f main framework A of the machine, has a milled surface and at one end a thumb-nut a, by which to rotate it by hand when de-' sired. A red 25, extending lengthwise of the machine, paraliel with the feed-roll a, i s pg; $5

"vide'd forits entire length with spring-fingers '26, which 'bytheir action upon the paper to be printed upon keep-the said paper closelyin contact with the feed-roll, the said bar and fingers constituting a presser and insuring c the accurate movement of the paper with the feed-roll.

The ratchet-toothed feed-rod a (see Figs. 1, V

and 5) is surrounded between the-guide-arms b of the indexplate B by a pad-carrying sleeve 27, which slides on the said rod a in unison with the index-plate as the latter is moved by hand. The sleeve 27 is cut out at as to bestruck by some-of the projecting length to enable the said inking-pads to be placed under the rubber segment carrying the type, the pads being left in such position type of the said-rubber segment a when the latter is depressed. The in k in g-pads (l d are also located some little distance apart to leave sniiicient space between the said inking-pads to enable the type on the type-segment to be forced against the paper to be printed.

The rubber segment 0', carrying the type, is provided (see Figs. 6 and 7) with a series of deep grooves 6, which separate the type one from the other, such separating-grooves enabling that one type of the segment immediately below the stud e attached to the printing-lever c, to be forced downnpon the paper without at the same time forcing downward against the paper other type ad cent to the one selected as next to print a letter.

The rocking lever f, loosely connected with the ratchet-toothed bar a, which serves as a bearing for it, passes between two projections 30 31, extending from the pivoted printinglever r, so that as the said rocking lever f is" depressed the printing-lever e will also be depressed, a spring 3:], introduced between the frame and rocking lever f at one end,

lever and rocking lever f tor moving the.

printing-lever, and the stop 33 for limiting go acting to raise the said lever and the printing-lever 0 when the hand is removed.

The rocking lever f, which operates the printing-lever e, vis provided at one end with a yielding project-ion or finger-piece 40, having a downwardly-projccting pin or stud 41, which cooperates withastop. (Shown in this instance as the milled head of the thumb-nut a \Vhcn the lever f is depressed by the action of the finger on the said finger-piece 40, the 'levcr e is depressed only far enough to compel the feed-dog r to move the carriage, thus forming the spacing; but when the said lever) is depressed by the action of the finger directly upon itt-lie movemcnt imparted to the lover a is sullicient to not only move the index-plate, but alsoto cause the stud c'- to depress the rubber segment far enough to print; but to prevent too, great descent oi" the said stud e" and lover a I have provided the regulating-lever is-mueh more readilyacces- 6o sible than when connected with the pinntinglever, as it is with the left hand that the machine is desired to be operated.

- A bell D is hereinprovideifonamlihlynzedicating to the operator when a line is nearly completed, such bell D beingherein located upon the pivoted.type-carryin" segment, the bell-hammer D being attache bye. yielding arm to the rocking lever f at or near its right hand end,so that as the bell moves from the left to the right with theindex-platein printing a line it will be struck by the hammer i? just at or before the line is completed. It1-s obvious that the bell may be otherwise ar ranged than that herein .described'li i'ithont 7 5 departing from this invention-such, for instance, asrcversing' the arrangement herein shown.

1. In a typewriter, the index plate and 8e type-carrying segment pivoted thereon, the guide-arms Z), and ratchet-toothed feed-bar a, combined withthe sleeve 27, mounted upon said feed-bar between the guide-arms and independent inking-pads carried by said sleeve,

and a pivoted printing-lever, all substantially as and for the purposes set forth.

2. In a type-writer, the pivoted printingthedownward movement of the printing-1evcr, combined with thespring-arm -iO,at tached to the said rocking lever, said arm having a projectiop 41 or equivalent for limiting by striking the thumb-nut .1 the downward 5 movement of the rocking lever whenthelat tcr is depressed by the operator acting upononly the arm 40, substantially as described.

In testimony whereof I have signed my name to this specification injhe presence of two ioc subscribing witnesses.
