TYPEWRITING-MACHINE.

Taal! whom. it 'may concern:

`'Be it known that we, EnwAnn Turnus ,and liunnumr C. STiCaNnY, both citizens of thc United States, said Tnrmiis resiiling in New York city, county and State of New York, and said S'rlon NnY residingy in Elizabeth.` county oi' Union and State of New Jersey, have invented certain new and nsoful improvements in Typewritiiig-Machines, of which the following;y is a specilication.

This invention relates to typewriting Ina-5' chines and more particularly to means for controlling thc character ot thc printing.

ln *"acticc, it is sometimes desired to have the writing in certain columns char acteristit'ally distinguished troni that done in other' columns. This may be done by writing the characters with types bt ditlerent size or conformation, or by printing` thc characters through ribbons of different colors.

The distinctive printing may be accomplished according to a predetermined plan, to relieve the operator of the necessity of manually changing the character of printing; and a feature of the present invention is the provision of improved automatic means of this kind.

AV column-selecting device is usually the most eiiicicnt way of locating the carriage in a predetermined column. and the means for changing the character of printing is preferably connected to the column-selectin r keys to be operated thereby.

:The typewriter carriage, however, may be fed into the special zone in which the distinctive printing is desiredby its ordinary escapement mechanism, or otherwise than by tabulating. As it is sometimes desired to determine whether the carriage entered the special zone by the column-seleetingjr mechanism, or by the cscapement mechanism, or otherwise, We n'oride mechanism which will' cause die printing in the special column, when the carriage is thus positioned, to be distinctive not only from the ordinary work but also from the Work which is (lone in thc special column, when the carriage is located thcrin by the Column-select ing mechanism.

In providingr for the distinctive printing while the carriage is in the special zone,

21, 1916, Serial No. 133,159. Divided and this application filed Decem- Serial No. 267,440.

after being positioncd there by the ordinary letter-feedingr escapcn'ient, we have found it cmivcnient to utilize the bichromc ribbonshift of the machine, so as to change the color of the printing. The bichrome ribbon usually co'nprises two distinctive colors,

one oi' which is usually red and the other black'. This bichronie shift may be con- ;trollcil by a iupr settable along the carriage; 'and this lug; may bc part ot the usual tabuf lator stop.

ln order not to burden the typewriter carriage with the actual operation of the ribbon-shifting mechanism, and in case the typewriter carriage should pass the special zone without any printingr being: done therein, We have provided mechanism whereby the carriage simply positions certain mechanism, which causes` the shifting;r operation to take place, when the type keys are operated to print. This mechanism may comprise a bail extending across the entire zone, and adapted to be operated by a lug on a tzibulator stop used to locate the carriage in the special zone. Connected to this bail by suitable mechanism, may be provided an interponent in the forni of a universal member, which is moved by the operation ot' the bail beneath the type key levers of the machine. T his bail may have suitable connections to the bichrome ribbon-shift of the ma.- chine.

This ap 'lication is a division of our application erial No. 138,159, filed December Q1, 1916 (now Patent, No. 1,312,145, dated August 5, 1919).

Other features and, advantages will hereir.' 'fter appear.

In the usual Underwood typewriting machine, alphabet keys 1 and numeral ke s 2 depress levers 3 to rock bell cranks 4 w lich are connected to swing type-bars 5 upwardly and rearwardly against the front side of a, platen 6, mounted in a carriage 7. The car-- riage 7' travels step by step at cach depression of a numeral key by means of the usual escapement dogs 8 and 9, which are eliective on the usual cscapelnent wheel l() permitting the .'arriage to he drawn forward by a springr barrel, not shown herein. "lille ca"n ringe is fonti-oiled by said escapement wheel through a ravir ll swingable on said cai ringe, but normallyv meshing with a pinion l2 conm-.chal willi said esrapement wheel. To permit said esrapement wheel to turn, the dogs 8 and 9 are rocked at each depression oi a numeral key, by means of a universal frame lil, which is actuated by a heel 14. on each type-bar as it approaches the platen. In addition to the above-described forward letter-feed of the carriage, the Underwood typewriting machine usually includes a tabulating mechanism for rapidly positioning thc'typewriter carriage at any one of a number of selected letterspaces. For this purpose, the machine is provided with decimal tabulating keys l5 mounted on the front ends of key levers 1G, pivoted at 17, so that when any one of said keys is de pressed, the rear end of its lever will rise and lift a plunger 1R. so that the upper end thereof, forming a counter-stop 19, will lie in the path of any column-stop 20, which is in effective position, said column-st0ps being adjustable along a rack bar 2l, which includes teeth at letter-space intervals.

In the present machine, the mechanism is somewhat modified from the usual Underwood mechanism and is of the illustrated in the patent to Vl ernery, 1,108,415, August 25, more in detail in tion No. 782,391, filed August 1, 1913 (now Patent No. 1,292,151, dated January 21, 1919). In the mechanism illustrated in said patent and application, the column-stop bar 21 is normally raised so as to hold its stops 20 out of the reach of the counter-stops 19 even when a counter-stop is projected, as above described; the rack bar for this purpose comprising arms 22 which are pivotedV at- 23 on the typewriter carriage, thus permitting a spring 24 to normally hold Said rack bar in its elevated position.

Whenever it is desired to perform the tahulating operation, it is necessary in the present disclosure of the invention to depress both a decimal tabulatinr key l5 and a column-selmfting key 25, am the connections are such that whenever a column-selecting key is depressed, the rack bar 21 will be swunf downwardly when the column stop 2() tiereon approaches the proper column, witli the result that the stop 20 then lies in thepath of the elevated counter-stop l9. in which the tahulating is to he done must be lirst determined by tho column-selectin r. key 25 and then the particular letter-space in said zone is determined by the decimal tabulating key l5, which. in thel meantinuf, has been depressed. ln miler to bring about this resuit, the columnselecting keys 25 are effec tive to depress the rack bar 2i only when suivi rank bar has brought the stop thereon approximately to the beginning ot' the desired zone or column.

l`o iuwoinplisli this, the colinnueselecting lzeys 25. which are mounted ou the front ends of the key levers 2G, pivoted at 27, raise at their rear ends, column-selecting `bars 2S, which normally are lnefective on the rack bar' 2l, but which are each adapted to tension their suit that when the stop 20 arrives at the proper column, the spring 29, which is tensioned by its column-selecting key, will depress thc rack bar 21, this being accom plished through connections to be described presently in' detail, but which include a lever il!) comprising a roller 3l, rolling on the rop of :i plate 32. fast to said eolunnrstop rarkhar til. llvhcnever a spring' 29 is thus tensione-d, it tends to raise a slide 33 on its har 2H and as soon as it can raise said slide` the slide will rock the lever 3U by means of a bail 34, which passes thro'ugh slots 35 in all of the slides 33. This bail is fast t0 the rear end of the lever 30, which is pivoted on a shaft 36, and has a rearward extension 37 carrying said bail. From this it will be seen that the depression of a given column or zone-selecting key 25 tends to make the slide 33 rise, and if said slide were permitted 4to rise at once, the lever 3() would depress the rack bar 21, so as to carry the column-stops thereon within the range of any elevated counterstop 19, and thus the first columnstop 20 would arrest the typewriter carriage by colliding with the elevated counterstop 19.

In order to revent this, the column-stops 20 are adaptedD to operate a slidable locking bar 38 which prevents any slide 33 from prematurely becomin l effective to move the column-stops 20 Wtliin the range of the own springs 29, with the recounter-sto s 1-9.

These interponents are shlftablealong the rear ends of the key levers 26 of the column-selecting keys 25, and are adapted to occupy either a forward ineffective position or a rearward effective position, according to the position of the revoluble heads 70.

So that the operator may readily set these heads 70, each of the heads is provided with a window or opening through which either the indications A or may be seen, avoiding to `the position of the head. Then the character A is visible, the key will not automaticall shift the platen when operated, but w en the B is visible the iuterponent 73 is in position to cause the column-selecting key 25, to automatically shift the platen when depressed. The operator may, therefore, b revolving 'the head 7 O to either position X or position B, determine whether or no't the column-selooting;r keys, for each individual column, shall automatically shift the platen to upper-case position when said keys are used to locate the position.

When the column-selecting key 25 is depressedv and rocked about its pivot 27, and the interpellent 73 thereon is in e'ective position, the upward movement thereof, causes the interponent to strike andv lift e bail 74, overlying the interponents and fast tol a rook shaft 75 journaled in the frame of the machine. Secured to the rock shaft 75 is an arm 76, which is moved downwardly when said shaft is rocked. This arm 76 is connected by a link 77 to a bell crank 78, havinv an arm 79 `engaging with lever 62 of the usual Underwood typewritlng machine. As the link 77 is drawn downwardly, by the upward movement of the bail 74 caused by the interponent 73, the arm 79, of the bell crank 78, eu ages the arm 63, of the shift key lever, an operates the case-shift mechanism, causing `the platen to be shifted to upper-case position. The arm 63 thus being moved, causes the forward end of the shift key lever 62 to be depressed and locked in depressed position by the pin 68 thereon engaging' with the latch 66.

If, after having shifted `the platen auto matically when positioning the carriage by the column-selecting keys, the operator for some reason, desires to print the same form of characters as in other columns, the latch 66* may be manually moved by the handle 69, to free the pin 6'8 therefrom, thus permitting the shift key lever 62 with the platen, to return to normal. lower-case position. y

According to the present character of printing is though the carrie. has been positioned in the special zone other means than the column-selecting keys, and when so positioned, the character-.of printing s entirely distinctive from that done in other columns, and also from that clone in the special co1- umn, when the carriage is .lpositioncd by the column-selecting means. 4or this urpose, we have found it convenient to utilize the usual bichrome ribbon mechanism of the Underwood ty ewriting machine to change the color of t e rinting. Said bichrome mechanism inclu es the usual ribbon viinvention, the changed, even brator 66 through which the bichrcme rib-- bon is threaded at the top, said bichrome being actuated by a iever 8l. This lever is adapted to be given various throws, aocordin to the color of rinting desired, and the eo or of the printing is varied by the fact that the top of the ribbon, forexample, as shown in Fig. 9,-may he black, whereas the bottom of the ribbon may be red. Thus a small throw of the lever 81 will cause black printing, and a larger throw will cause red printing. The varying throw of the lever 81 is obtained b the usual bichrome actuator' of the Tnderwood machine, said actuator benv in the` form of an open box, best shown 1n Fig. 9, as comprising' a rear side S2, a black printing Side 83, and a red rinting side Sei. This actuator as usual, 1s mounted on the universal bar or frame 13, at the rear end thereof, and is shiftable -sidewise on` Said frame by means of a link 85, for the purpose of bringing `either. the. side 83 or the side 84 in engagement with one orthe other of actuating pins 86 and 87, The side 83 has a slot in it in which the pin 86 can work, and since said pin is' remote from a Jivot `88 about which the lever S1 works, sai pin.

will give said lever 81 a comparatively small throw. The shape of thisslot is best shown in Fig. 7, where it appears that the slot is vertical, andthat its sides lit the pin 86 closely. The side 84 of the actuator box has a somewhat similar slot which actuates the pin 87, and since said pin is comparatively near the pivot 88 of the leverv 81, it will give said' lever 81 a. comparatively lar e throw, thus bringing the red stripe of t e' Vizy'pevvriter ribbon to the rinting point.

e actuator box' is `slidab y held in the usual manner `on said universal bar or frame 13.

VThe red printingpart of this mechanism is automatlcally brou ht into play whenever a number `1s wringen in a special zone, but has been written `'without previously iso positioning the carriage by operating the column-selectingr keys. Y

To bring about this result, this ronnec* tion is herein disclosed as connected to the column-stops of the typewriter, sint-e these stops are customarily used for sehen ing the sperial Zone, and in the present in vention are used to an even greater extent than in some Inaehines for said purpose. The rolnmn-stops are effeetire to determine whether the machine shall write in red or black, by lneans ot an arm S) pivoted at the rear of the machine, on which arm they are elieotive through a oaxn 90 fast on said arm. The arrangement ol the Cointrin-stops 2li and the earn D() such that it no eohunnselertingr key has been depressed1 the eoinmn-stop 20, it travels along with the typewriter carriage, will engage (see Fig. l) and cani outwardly (see Fig. T) the cani 30, with the result that the arm S9 on which said cam is fast, is swungr rearwardly and rocks its color control shaft 9i.

Fast on this shaft 91 is a rook arm 92, which has pivoted upon its dependingr lower end a vforwardly extending earn-operatiup,r link D3. rIhis link operates a cam for the purpose ot compelling the keys. when said cam is in its effective position, to shift the ribbon so that the printing will be done in red. This is effected by putting a ribbon ,shifting member 94 under the keys of the typewriter, which is adapted to shift the above-described actuator 82 from its normal black-printing position to a position in which it causes the printing to take place in red. It will be noted that the connections may be such that this ribbon-shifting meind ber 94 is operated only by the numeral keys of the typewriter, with the, result that the alphabet keys of the typewriter may write black in any Column, whereas the numeral keys are compelled to write red in a special column when the column-selecting` keys have not been operated.

'This ribbon-shifting member 94 is in tho form of a bail having upstanding a 'ins 95, one of which is adapted to lie under every numeral key. the intervening spaces being left for the operation ot the alphabet keys of the typewriter. The bail 94 is splined on a transverse rock shaft 9G, and is normally drawn by a spring 97 in such a way that the opstanding` arms are clear of the numeral keys of the typewriter. iVhen, however, a columnselecting stop 20 strikes the cam 90, as described above, so as to shove the camoperating link 93 forward.` the link carriesV its cam 98 forward, so as to thrust the bail 94 sidewise by a pin 99 fast thereon. This thrusts said bail 94 so that the arms 95 thereon are in their effective positions under the numeral keys. lith the parts positioned thus, every time a numeral key is depressedq it will rock said baii 94 and the shaft 96 on which the bail is mounted. then the shaft J6 is so rocked. a rock arm 10i) thereon draws clown a link lOl attached to a roek arm illi on the usual colora-ontrol shaft lllll ot' the linderwood typmvriting nun-bine. rilus color-control shaft includes the usual rook arm lili. i which is pivoted the actin :dor-shiftingr` link H5. and this link.` when shifted to the right. as seen in. Fig. Si. canse-s the uiarhino to write in red.

The iink h5 is normally thrust to the left by a spring?r 1117i foiled around the shaft W3, and shown in Fig. o. Those connections'` are sluh. therefore, that the ribbon coni'neiions norlnaliy stand so that they will print in blank.y but whenever a numeral key operated. the ribbon shit's to red. il the cam llfl engages' the eohmnrstop Ell. The eolorrontrol shaft 103 may be extended in front of the trame of the typewritinlh` machine, in order to enable the operative to eontrol the nolor nuinually, and may be provided with a suitable key lllt. whereby the ribbon may be held down to print red when it would otherwise print blark. In order that the key.`- need not print red in a special Zone.y the rau! fill is so placed that when a columnselertiug key swings the rack bar 2i downwarflly.y it rai-ries every e'oiunnrstop 2l) thereon below the lerel of the ram 90. so that said Cani is idle, and the connections between thc keys and the eolor shit't are irwti'oeti've.

lfu order to make the equipment of the nun-bine as simple as possible, the columnstops 20 may have their sides of two torms1 or be unsyininetrical, as seen in Fig. l. ete.. one side being ent away. as seen at 107 (see Fig. Then this eut-away side is uppermost. the cam il!) is always entirely ont ol' rearh of the eolunfin-strnos` so that the nou-bine.y then. will write normally in black in every column. or in any column in which the rolurnn-stop 20 is appropriately set.

Variations may be resorted to within the sropo ot the invention.v and portions of the improvements may be used without others.
