To all whom if: may concern:

Be it known that I, CHARL S T. MILLER,

J12, a citizen of the United States, residing in Brooklyn Borough, in the county of Kings, city and Stateot New York, have invented certain new and useful Improvements in 'lypewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly to'tabulating devices for such machines, and is herein disclosed as applied to an Underwood standard typewriting machine.

The invention as herein disclosed is a decimal tabulating device which is adapted to be actuated by the numeral keys Off the typewriting machine, and is especially adapted to be incorporated in machines of the usual type with the minimum amount of As herein dismay be proare slightly modification or special work. closed, the usual decimal stops vided with key levers which shorter than the usual levers, so that said levers, instead of extending to the front of the machine, may terminate substantially beneath the front of the numeral key levers, and are connectible to the latter by normally ineffective connecting devices.

The connecting devices may be in the form of hooks adapted to engage studs on the numeral key levers, one book being pro vided for each tabulating stop and corresponding numeral key. The hooks may be normally disconnected from the studs and may be swung into engagement withthe studs by a bar which extends across the bank of keys and lies between the numeral bank and the next bank below, thus being out of the way and yet enabling the mechanism to he compact.

The connections may be such that the usual numeral key levers, which print when depressed, are not carried down to the same extent when connected to actuate the decimal stops, with the result that printing is avoid- I key levers may be effective by actuationot a conveniently placed key, which is automatically returned to ineffective position when,

released.

Other features and advantages will hereinafter appear.

In the accompanying drawings, pFigure 1 is a diagrammatic sectional side view or an Underwood standard typewr tmg machine, showing the present invention as applied thereto, the machine being in normal condition :tor typewritingp Flgure 2 is diagrammatlc side view,

Figure 7 is a view on a smaller scale, simi lar to Figure 3, but showing the key top rotated to display one tabulating legend and conceal the numeral. 5

Figures is a fragmentary side view, showing the connecting key depressed to connect the numeral keys to the tabulating devices.

In the Underwood standard typewriting' machine, alphabet keys 10 and numeral keys 11, when depressed, carry down'key levers 12, rocking sub-levers 13 to carry type bars 14 upwardly and rearwardly, so that types 15 thereon print against the "front side of the platen '16, journaled on a carriage 17. Whenever a numeral key 11 or alphabet key 10 is depressed, it feeds the carriage 17 along the distance otone letter space when released, and. tort-his purpose each type-bar 14: is provided with a heel 18 which actuates a segmental universal bar 19, as the types 15 approach the platen. This actuates" the usual escapement device, and permits the usual spring barrel 17 to draw the carriage 17 along the distance of a letter space,the carriage for this purpose being provided with a pivoted rack bar 20, which meshes witb'apinion 21 connected to the escapement wheel, When a key 10 or 11 is released, it returns to normal position under the influenceof its returning spring 22. The carriage 17 travels in the manner described on a" front rail 23 and. arear rail 24:.

When it is desired to bring the carriage 17 rapidly to a more or less distant letter space in its travel, the tabulatin r mechanism may be made effective by depressing a linger-piece or connecting key which is pivoted by a shouldered screw 26 on a bracket 27, held by screws 28 to the frame of the typewriter inside of a side member 29 at the end of the keyboard. \Vhen the key is depressed, a cam 30 on it rides down upon a universal bar or bail 31 which is mounted in arms 32, vpivoted to shouldered screws 33 each fast in one of the sides 29.

As the cam 530 descends it rocks the bar 31 riuirwardly, swinging he connecting books 34 rearwardly,because it bears against the front sides of said hooks. llach hook 3% is pivoted by a shouldered screw 35 upon the front end of a decimal-key lever 36 pivoted intermediate its ends at 37, and adapted to lift its one of an array of counterstops 38 into the path ot a column-stop 39. adjustably mounted on a rack bar 4-0. fast to the usual brackets ti on the typewriter carriage. To enable any hook 2-34 to carry down its key lever 36 in the manner described, each book is provided with jaws 42, whiclu at the depression of the connecting key are adapted to extend over and em brace a stud 4:25 on its numeral key lever 12, so that the depression of the numeral key will carry down the tabulating;- lever 36 to quake its stop 38 effective.

In order to release the carriage from the pinion 21 to enable it to travel until it is arrested at the proper space by a oohu-nnstop 39, when the latter strikes the counter stop 38, there is provided a carriage re lease device which may be much of the usual sort and includes a short universal. bar 44 overlying heels 45 on the counter-stops 38:

said universal bar, when actuated, adapted to lift the rack bar 20 clear of the pinion 21 and allow the spring barrel 1'? to draw the carriage to the left until arrested by the column-stop 39 striking the raised counterstop The connections for lifting the rack bar 20 include a. roll 4-6 on the front end ota, lever 47 pivoted intermediate its ends and connected by a link 1th to the rock arm l9, fast to the shaft 50, which latter fast tothe universal bar i l. The roll ",6 when raised runs on the usual tlat margin o i the rack bar 20. Y

It is found that any tabnlating lever 36, it pivoted at the usual point, nearly inte.'- mediate its ends will raise its counter-stop 38 to the proper position determined. by the usual arresting bar 51 even though the numeral key actuating it is only depressed far enough to raise its type-bar lat to the Figure F or limiting the travel of the counterstops 215 there may be provided notches 52 of much the usual length thus answering the purpose just described. in order to norinally keep the hooks 23 i; clear of the numeral keys and keylevers, each hook is provided with a wire spring 53 which is coiled aroun zl a washer 53, interposed between each hook 3i and its lever 36, and normally throws its hook forwardly to the Figure 1 position against the bar 31. in the ineiilcctive position of the latter, The throw of the bar 31 is limited by the end of the cam slot 56 which normally engages the bar 31 since the connecting key is normally held in its uppermost (liigure 1) position, by a returning spring 57 coiledabout its pivot screw 26.

To limit the rearward travel oi. the bar 31, the arm 32, which carries the bar 3.1. may be provided with a tail which is adapted to engage a pin 59 fixed in the adjacent side frame 29., it being so located that it arrests the bar 31 with the jaws e2 fully engaged with the studs 42h and yet not creatinsr rious triction of the bar 31 on the hooks ill. in order to e ive the key the right feel to the t iq'iist the cam 30 adjacent the bo tom 56 is quite steep, but at point 58 becomes a dwell 60 which holds the bar 31 substantially with the tail 58 against the pin lt found that the bar ill may rest against the downwardly sloping portion ('31 ot the key levers 12 ot' the alphabet keys It), and yet bear far enough down on the backs oi the hooks 34- to enable the nunueral ken, ill to fully t epress the hooks without carrying; them beneath the bar 31 and beyond its control,

Each numeral key 11 above referred to, is preferably provided with a special body 62 and a top (l3, so that the top may be rotated to display the mimeral printed by the key, or the decimal place at which the key will arrest the carriage when operated in either of two systems of pointing o'tl numbers. F or this purpose the bodies 62 are made fast to the key levers 12 in any suitable manner, and the rotatable tops 63 include annular rings M having; lugs (35 which are aih pted to be turned under the bodies; The i numerals and tabulatingr data ori-1n 5; the legends tor the keys may be printed upon the (03s oi? the bodies 62 and show bencaih the glass (36. Above the glass. and fast to the ring (5i, may be a shield (5'7, which covers levers extendng 3 0 one of three denr ions 3'0, so ,.o hold the cover 6'? to dis 'ilay one of the three lcgeinls. i The numeral keys ii are steadied against side-wise; movement by the usual con 1h T1,

and, to hold the hooks 8 71: ,npright, there is provided a comb 72th:: the key levers an. The lit oi the hooks 3% on their screw pivots and washers 52-3 is close enough to ensuretheir proper co-eperatioi'i with the nu- 'meral he though the'studs are short enonghto clear" the adjacent v 1 levers 12 and studs til, even i he nun'ieral type usual up per and lower bars fnay incinr case types, and the kev-heads may bearjcoratspondmg upper and"lower-case designa- "trons.

Variations may he resorted to within the ,scope of the invention, and portions of the improvements may be ,used without others.
