Toll whom 'it may concern:

Be it kno`wn that I, RUSH E. MARTIN, a

citizen of the United States, residing at.

Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certaln new "and useful Im rovements in Ty e- Writing Machines, of which theffollowing is a specitication.`-

My invention relates-to improvements in type-writers, andv especially to improve- A mentsin that class of typewriting machines "having a type basket and a single-lettter t 'pe movement, s'uch as the Remington and ensmore machines, andthe objects of my invention are to increase thespeed of execuwritingj machines, s

adapted to print syllables of three letters or tion and the utility of typewrting machines. I achieve these results by addmg tothe ordinary mechanism of said class .of typefurther mechanisms words or syllables of two letters, and `pro vide a space, syllables of four letters or words orsyllablesfof three letters andprovidea s ace, lsyllables Aof live letters or words A or sylla les of four letters .and 'provide a' space, syllables 'of sin-letters or words or syllables of 've letters andl provide a space, and further, if desired. It isobvious that where an entire word or terminal Asyllable is printed the space should be added by. the escapement-'as hereinafter stated. I thus print the shorter words of plural letters, or

a word andmprovide a space bodily' bya single yim actof the type.

Figure 1 is a pian view of my device; Fig.

2'is a side elevation illustrating the opera? tion of my invention, jand Eigis a rear view of the same. vFlg; 4 1s a slee view .of

one of the key-levers'operating the singleletter escapement.I Fig. 5. is a side view of one of 'the keylevers operating the wordescapement'. Fig. 6 ,is alfront view, and Fig. V7 a` side view of the escapement frame. Figs. 8 and 9, 10 and l1, 12 and 13,

. 14 andflareside and front views of the lrespective escapements. Fig. 16 is a detail view ofone of the type heads.

In my invention much larger than the ordinary basket used in said class of machines, and I 'arran e the `single-letter types at the rear of the asket In the rawings illustrating my devinez-'-` construct .the basket and they are dperat'ed inthe same manner and by the. same key-board as sOrdna'rily usedin suchclass of machines. The type" heads carrying the words are arranged at lthe front part ofthe basket. The -spac'is entirely 'effected bythe escapemet. "IC'D- videtwo words on each word type-hea' so thatthe upper word may be printed bythe use of the ordinary shift key. i

In my invention I arrange upon the keys, wordsA to correspond f'w'it the word type-headsl in the basket; 4

The arrangement of the key-boardliij7 be adapted to suit the convenience'o'f the operator or to the particular .class of'business'for which .the particular machine lis desired. In the newspaper business certain words are most frequently used and the k"- board can `be arranged accordingly. -jn court" and l'awwork a different set 'of words is most frequently used and the4 key-board ycan be arranged accordin ly; and thesame ap lies to other classes o business such as rai road, grain lumber, paper, etc.

, A further o ject of my invention is to provide escapements relative 'to each class of words that may be operated by key-levers further'bals.' 'or sets of keys outwardly and rearwardly from .the ordinary key-board, and

to move the paper the pro er distance to allow the type-head to ,print the deslred length of vword and provide the desired machines of said description, and 7, 7,7, etc. l

represent the word ke' -levers Each keylever 7 rocks upon the ulcrum rod 8,`which, extends through an eye, 8 in a lug 9fen the keyfle'ver for that purpose. The fiilcrum rod 8 isV supported by the standards 9-9 attached to the frame. Each keylever 7 is provided with a lug 15, having a.

-U-shaped slot 1 6.-

17-17 etc., represent escape'ment support- 5 ino' frames which slide u ward and downward in perpendicular guides"34, 34, 34 etc.

provided at each side. t

In Fig. 2 the side rail of each frame is cutaway to show the bottom rods 18, 18, 18

etc. Downward pressure upon the-key 5 rocks the key-lever 7 upon the fulcrum rod 8 and raisesthe opposite end. The rods 18, 18, 18 etc. pass through the' U-shaped slots 16, 16 16, etc. 'and are carried upwardly at each pressure on a word key.

19 represents the top-rail of lthe frame andv supports one of the escapements, as 22.

In my invention I arrange the frames 17,

17 etc. to the rear of the general mechanism 20 of the machine, and I suspend the ratchet t bar 24 by hangers 25, -25 which are rigidly attached to the release lever rod 26, said rod being journaled to the carriage frame at 27, 27. The holding ratchet wheel 28 1s keyed to the end of the shaft 29 which'carries' the single-letter escapement 30.. By this constructionl do not disturb the ac- Ytion of the regular mechanism appliedto the single letters, andam able to locatdthe 30 entire word escapement mechanism to the reir of the regular mechanism. Theratchet b'ai 24 is detained by engagement of one of its teeth with a corresponding-tooth of. the

holding ratchet wheel 28. `When releasedv from this engagement the bar 24 is moved with the carriage vby the ordinaryA carriage spring 37, provided for that purpose.

By downward pressure upon one of the keys 5, one of the escapements as 2'0 is 40 brought upwardly into engagement'with the lateral teeth upon the ratchet 'bar 24 and vraises said bar free from the holding ratchet wheel 28. The carriage spring, as 37, aforesaid, then o crates to `move the ratchet bar 24 ily and revolves one ofthe escapements, as 20, in engagement therewith, untill the lug 31 strikes against the st op 32. At `the same time the downward pressure' upon the key 5 operates the type-bar 33 and foi-'ces the type-head 14 upwardly against the platen. This operationwill print syllables of three letters or words of two let- Aters and provide one space. As soon as the..

key 5 is released `the escapementas 20, drops by gravity -out 'of engagementwith the ratchet bar 24, and said ratchet bar 24,

. same manner the escapements 21, 22 and 23 may loe operated to print syllables orfwords provide a space. ycapement 20 is provided with three teeth,

einem of four letters and provide a space; syllables or words of sinA letters, or of live letters and For that purpose the esthe escapement 21 with four teeth, the escapement 22 with live teeth, and theescapement 23 with six teeth, and the escapeinent wheels revolve a corresponding vdistance between the respective stops 32 and 36. In the operation of the. escapements, as 20, against the ratchet bar 24 the first engaging tooth upon the escapement is. alwaysv farthest to the right and uppermost when brought to the engaging position, as shown in the drawing Fig. 3.

By reason of the arrangement of the frames in the guides 34, 34, 34, etcrit isnecessary to off-set the escapement supporting standards 39, 39, 39 etc. at dierent degrees (except one of the escapement supporting standards 39, supporting escapement 21) each of lsaid standards being offset at a prop er degree to bringthe escapernent, as

22,'1n perpendicular alinement 'with the ratchet bar 24.

It will be observed that the word typebars as 33 must be arra-nged'in the .basket in front of the fulcrum rod 8 so that the downward pressure upon a key5 will operate a type-bar bearing a word type, as 14. 4The eyes 8 are located in top lugs 9 so that the fulcrum rod 8 extends abo've' the ordiinterfere withv their operation. l

In the operation o f my .inventionthe 0perator by pressing4 downwardly upon one of the keys 5 actuates the type-head 14 up-' wardly toward the platen, and at the-same timeY by the'rocking of the key-lever 7 upon nary keV-levers of the machine and does not the fulcrum rod 8 the opposite end of the key-lever 7 is raised and carries with it onev of the escapement supporting frames.v The full downwardpressure upon the key causes the escapement, as 22, to engage and raise the ratchet bar 24. The 'strength of the carriage spring'37 is much greater than the strength ofthe escapement spring 35. The carriage is moved horizontally by the tension of the-carriage spring 37, compressing the spring 35 untilzthe lug 31st`ri-kes against the stop V32. A spacel is then' aorded for l'the 'striking of the word type-head 14 against the platen@ As soon :as key 5 is re- Aleased the escapement, as @20, drops by ravity ont, of, engagementwith the ratchet O bar24, and the ratchet bar" 24,"Lby,gravity and spring pressure, descends into vreengagement with the hold-ing ratchetwheel 28.

The operation of my inventiondees not in any manner interfere with the operation 'of' the single-letter keys.-

The rods 18', 18, 18 etc. .extend through 'all @insee of the U-shaped slots 16, 16, 16 etc. of each respective series of Word key-levers. When a Word key-lever is operated it raises the escapement frame, as 20,'and the rod 18 is permitted to travel in the U-shaped slots 16, 16, 16, etc. of all otlierword key-levers in said series Without interfering with or actuating them in any Way.' For this purpose the slots are made Wider at the top so as to give a free action to said rod 18.

The U-shaped slts 16, 16,16, etc. are of sutticient depth to permit the operation of the rods 18,18, 18 etc. below the range of the ordinary single-letter key-levers, and likewise to permit of the operation of the ordinary single-letter key-levers Without coming into contact With said rods 18,' 18, 1S, etc. y

Having thus described my invention 'what u I claim to have `invented and desire to secure by Letters Patent is l. ln a. typewriting machine of the class described, the combination ,Withjthe ordinary mechanism of the machine of one or more series ofword key-levers, a 'fulcrum rod extending through eyes in the keylevers, escapement supporting frames, perpendicular guides for the frames, dependent lugs integral with the key-levers, near the rear ends, and having U-shapedslotsA Which inclose the base rod .of the escapement sup.-
