To all 'whom t may c'udnaem:

Be it,known that-L'JOHN MCTAMMANY, a citizenof'the United States', and a resident 'of Stamford,' inthe cohnty of Faireld and State of Connecticut, have invented certain new and usefullmprovements in Automatic Type-Writer Operators, of which the follow# ing is a specification.

' typewriter 1n a predetermined order' 'deter-l This invention relates to -an automatc ma chine controlled by a perforated mastersheet for'depressing the keys ofthe ordinary mined by perforations made in a mastersheet, the said sheetv being combined with mechanism which supplies power'tovthe typewriter keys in suchmanner'as to depress the same one by one. The invention has for its object', first, to provide a simple sheet-controlled operating mechaism'in which the power employed istransmitt'ed directly and positively tothe typewriter Skeys'without the employment of pneumatic or other like actuating means controlled by the sheet.

The invention also has for its object to provide an improved master-sheet, the key operatingperforations of which are designated vso that the letter or. character which operation; Fig. 5 represents a rear `elevation of the machine; Fig. 6 represents a sectlon 6-6 of `Fig-5; Fig. 7 represents a l a portion of the master-sheet.

on 1i i vviewldef 'T he same reference characters indicate the same parts in all the gures.

In .the drawings,-12, 12 represent the supporting portions vof the frame of an crdinary typewriter, and l13 represents one of thekeys or key levers, these belng parts of the' ordinary printing mechanism of the t newr-fter which forms no art of m'y in-. y` p with t e spacenhetween-two of the teethfQ f relie The mechanism embodving' myvintention.,

is mounted in a'ca'sing which constitutes a oase adapted to support the typewriter, saidcaslng, as here shown, comprising an lupper. section 14. to which the parts 12 of the type writer frame are detachably secured by 60' screws'v15, anda .lower'or' ,base section 16 supportlng these'ction14 and hinged thereto at 17 so that said section 14, and the typewriter attached thereto, may be swungupfwardly to ,expose .the `mechanism of the operator. 1,8 represents a shaft: mounted at its ends in -two opposite side-pieces of the casing section 1 4 andextending horizontally across the 1nterior. of said section. Upon the shaft 70 18 are mounted hubs 19 corresponding in number to the printing characters and key levers -of the typewriter and adapted to be independently rotated by friction as hereinafter described. To each hub 19 is attached 75,

a star lwheel 20, the teethl of which hre preferably 'formed as shown bv Figs. 1, 3 and 4.

21-,represent's a feed roll which is formed es .an elongatedv spur gear, said'ro'lllhaving L longitudmal vgear teeth 22 separated by'in- 80 terdental spacesof uniform width, the teethv being alsof uniform width.

` 23 represents a master-sheet of paperor fother suitable fieXible'ma-terial"having keyfoperating perforations 24.' The sheet 23;'85

passes between the feed rolli2l Vand the series of star wheels 20 .and is supported and driven by thefeed roll, the latter being provided at its central -portion'with radial pins 25,4Figs. 5 and 6, whichare formed on 'the 90 outer ends. o-f the gear teeth 22 and 'are adapted t'ente'r Vfeed orifices- 27 formed in the central portion of the sheet 23. The

perforations' 27 have' a function distinct `from from that of .th'e'key-operating oriv85 fces, namely,'to engage the pins 25 so that' there is always a positive feeding engagement between the feed rollandthe sheet 23.

The key operating perforations 24 are formed in accordance with the matter which 10Q i's to be printed by the typewriter, eachI perfox'vation 24" representing a printing character and key lever. As indicated bv Fig. 7 5 the key-operating perforationslalterlfate lengthwise of the sheet 'with the feed perforations 27 so that'a per-:

foration' .24 many-part of the ,sheet thatis passim the' feed .rplly 21 will cblticid'ri4 The feed roli and each ster Wheel 2O er .so relatively formed andV arranged the when iinperfo'rate portion of the sheet 2b is passing between the feed rolt and a.

5 Wheel, the teeth of the latter tviil bear inoperatively en the Sheet, as lindiceted ject through said perforation and enter the' space between two adjacent teeth oi' the feed roll, se that the ster Wheel is interengaged with the feed, roll and positively rotated thereby,as indicated by Fig. 4. This'move- ,ment of the star Wheel ie utilized to depress the corresponding typewriter-key 13 through the instrumentality of e. lever 28 fuleruined at :29 in the casing' section 11iand having one of its arms extending into the path of the teeth ef the star Wheel, tin-trete-v ing; ene lever 2S for ea'ch' star Wheel. The other arm of the lever 28 is provided with e coupling nieinher adapted to deteehably engage the correepending typewriter lrey 13. As here shawn, said coupling member includes en in7 er portion 3G pivoted at 3l to the lek-er 28. and provided with a, screwthreaded extension and en outer Jortion 33 haring e tapped eriice to receive the portion 3i? and e. key-hole siniped slot 34 adapt- 35 ed .to detaehebiy engage a headed stud 85 on a lrey 13. When e. star Wheel is :it rest the lever Q8 bears on thevupper side of one of its teeth, es indicated by Figs; l and 3, the key i3 being at the Same time in its" norm-.il 40 position.

feed roll through a key-operating perfor@- tion 24e in the muster-sheet, the arm of the lever hearing onthe star Wheel is raised, as indicated by Fig. 4C, and the opposite end is depressed, the depressed yend acting through the described connection to depress the key 13 and cause the printing ot the corresponding` character. The rotation of." the star '5G wheel is Continued until the engaged tooth recedes 'troin the. feed roll, the'star Wheel vagain assuming the inoperative position shown by Fig. 3, until the next perforation y 24 reaches 'ene of its teeth.I The feed roll may be rotated by any suitableineens euch as m electric motor 36` located in the casing section 16 :ind'a-train Vof gears connecting the shaft of the motorl with the feedroli. As best shown in Fig. 2, vthehuhs i9, to which the ster Wheels 2O 'are secured, are fitted close-together. and te the shaft 18 so that Whensaid shaft i8 vis rotated there Wilt be a constant tendency te rotate the4 said hubs- 19 in order that, Whenever e perforalVhen the star Wheel is engaged by theV end et a teot k'. teoti to @destinen n the lne-ritira v-to retnte 'the st Aing te e slieift t0 are perni-itt operating;
