TYPEWRITER.

Arplication filed December 19, 1922. Serial No. 607,854.

To (11/ 20/10/11 4'! may ('(HlC-Y'l'lt. I

i Be it known that I, Join, SMITH, a citi-, zen o-lithe United States, and aresident of Moran. in the county of Mackinac and State of Michigan. have invented certain new and useful Improvements in 'lypewriters, of

which the following is a specification.

My invention relates to in'iprovements in ,typewriting machines (or typewriters, as such machines are commonly called), and it consists of the constructions, combinations and mode of operation herein described and claimed.

An object of the invention is to provide a typewriter which is capable of producing printed matterin any one of a plurality of styles of type, 'or producing such printed matter in a mixture or combination of such various styles of type.-

further object, expressed more in detail, is to provide a typewriter which can he set to print lower and upper case letters in any one o'f a number of styles of type which it contains, but which may so readily be shifted that words, lines or sentences written in letters of another type style may be interpolattal for the .purpose of emphasis. etc, in the matter which is being written under the original setting of the machine.

A further object of the invention is to provide in the/foregoing machine, a style indicator so that the operator may know at a glance what style of type he has in the printing position.

Other objects and advantages willappear in the following specification, reference being had to the accompanying drawings, in which: i

Fig. l a planyieW of the improved type writer showing the setting of the type bars in segmcntslmth in front and rear of the printing platen, also disclosing other features of the invention for the understandingof which reference must be made to the accompanying description.

l ig. :2 is a longitudinal section of the typewriter (which might be considered as I talten substantially. but not. accurately. on

working parts of 'the of Fig. 1) clearly showing Fig. l is a. detail plan view of the type style indicator in Fig. 1,

Fig. 5 is a front View of the type bar guide through which the type bars pass as theystrilte the platen in the operation of printing, and Fig. 6 is a detail cross section on the line 66 of Fig. 5.

Generally speaking, this typewriter is so arranged that the operator may make an adjustmentto write in any one of several styles of type. F or example, the present typewriter has type in both large roman and italic styles. By making the proper adjustment, the typewriter will write in large roman style and by using the customary shift key will produce capital letters in that style. 7 i

The typewriter is also capable of Writing in italic style, but instead of arranging the mechanism in such a way as to render the necessary adjustments for writing in either one of the two styles permanent, provision is made to permit the operator to shift from one type style to another as readily as he shifts fromlower ease (small) to upper case (large) letters of the roman style. This is a feature that has obvious advantages. One may desire to emphasize some particular portion of the text under production.

The typewriter may be set to, produce.-

priuted matter inroman style. ,The operator may desire to set 011' or emphasize certain foreign words; phases, or even sentences. convenient and effective shifting to the italic style, and words. etc. written in this style and interpolated in the roman style of, type, will receive the proper recognition intended by the author. \Yith this brief introduc tion in mind, thereader may consider the details of the machine, whiclrdet ails are described under major subjects.

The frame con'iprises a eastih l which is the foundation by which all 0 the other structure supported. The tr. e has lugs or ears 2, only partly slunvnin ltigd. and a little more clearly shown in Fig. for the purpose of providing means to grip the frame so that itmay be conveniently. lifted. The frame also has feet 3 adapted to carry the usual pads to rest on'the desks.

A bridge 4; and supporting bar 4 extend from one side of the frame tothe other.

The bridge 4 furnishes the suppprt for the This is accomplished by the Very print capital letters in roman style.

The printing platen 12 being perhaps more closely associated with the frame 1 than with any other part, i: therefore described under this subject. It is mounted on a carriage 13 (Fig. 2) which is merely indicated in dotted lines so as to disclose its general location. The arriage adapt ed to run on a travel way 14, which in turn is adapted to move longitudina i of the frame between the front stop 15 (furnished by a part of the frame 1) and the hack stop 16. This,longitudinal movement oi the travel way is accomplished by the case shift. key 11, and obviously, moving the travel way as described, will move the printin point in relation to the frame so that a capital character which otherwise misses the printing point, will then strike it.

Fig. 3 illustrates how the carriage travel way 14: is shifted. A shaft 17 runs of the frame and is supported in bearings 18 at the ends. Adjacent to each end. the shaft 17 carries a bell crank (onl one be ng shown in the drawings) having! a vertical arm 19 and a horizontal arm 20. The one connects with a in; 21 on the underside of the 1. tavcl way 14, while the other cenn'ecls with a link 22 in turn ei'inncrtml at 23 to the lever 24; of the *asc shill; key ll. mentioned before. A block 25 supports a link .36 which has pivotal connection with a bearing; 27 adjacent to the rear edge of the travel-n This link is necessary to assist in support- 7 ing the travel-way.

A four-point suspension is furnished to the travel-Way 14 by the hell crank and link connections just described, it being" understood that the duplicate of the arrangement in Fig. 3 occurs on the opposite side of the frame which would be at the right in Fig. 1. It seems an obvious expedient to provide a three-point suspension by employing the same'arrangement disclosed in Fig. 3, with the exception that onlyone link 26 would be used and in such case the link should situated to support the travel-way in the centei ait the rear edge and thus take aposition at one of the three points of a triangle.

A spring 28, connected between the arm 19 and a. bracket 29 on'the bottom of. the

frame,' kee s thetravel-way Ll in normal contact Wit the front sto 15 of the frame. A spring 30 (F g; 3, rig t er id) leeps the 1 sense shift lever Ell normally do. (inc and of the spring; is suitably secured to the spring bar 31, while the other end has a suitable conncetion to the shift lever.

llhcre is another shift lever at the right side of the machine so that ashift from lower case to upper case characters may be accomplishciil from. either side of the frame. This other shill; lever designated 32 in Fig. i. As stated before, ithas operating connections with the travel-way l l idcnti cal to those shown in Fig. 3. Both shi'lt lovers are connected toa cross bar 33 at the rear of the frame. This cross bar is journalled if"; a hearing block 34-, and the cross ha; is siloa eo helow the connnon pivot rod oi the typewriter hey lovers 36 ot which there are lo iy-two as shown in Fig. i.

The case hilt lock down had best he dcscribcd in connection with the case shift key ll. an"! :hitt lever 2t in Fig. 3. I s purpose is to hold the carriage travel-way ll hack against the stop l6 so as to retain the correspondiugly snil'ted position vof the printing point. should the operator desire to write inpupplu' case characters for any prolonn'm lol'lOCii. By use oi? the shift lock the printingplaten l; is held in. the rearinost position so'tho't upper caseor capital letters of any of the Lypcstyles in which the machine is capable of writing and for which it may be adjusted, may appear at the printing point.

This shift lock down is very simple. The shank 3%? oi the key (Fig. 3) has a'hingc connection flh with the i'ronl end of the lever 24. vThe shank includes a catch 39 which, i 2 l ordinary depression of the shift lever,

avoic me shoulder i-O (Fig. l) of the lockinn 1 r ti. lint upon turning the shank .l' to and the. lett (Fig. 1), having first depressed the shitt key, the catch 39 is moved under the shoulder l0 and so holds inc shift key and lover down.

To facilitate the turning of the shank 37, the key ll includes an upturned flange which terminates in abutnmnts l-Q on each side at the front. 'lhcse are useful in taking the side thrust of the lii'igrcr in either moving the shank 37 toward the left (as stated) to obtain ti o lock down, or to. and the right to release the latch 39 from the shoulder 40. The shift key 11 is kept, in the desired nor-' mal position (Fig. 1) on the shift leverzl by a spring %8 (Fig. 3) which has connection between a lug 4% on the he and a lag on the lever. Another smal lug 46 (carried by the key) is arranged to engage the side or the lev r near the top edge, as shown in 3, to limit the turning move ment of the shank 3? under the influence of the spring. will become obvious later that the foregoing iockdown means may he applied to the style shift lever as well as to the Case sh ll lever, although the drawing '60 of the type basket.

a generally oblong shape, including parallcl side arms 47 and semi-circular ends which are made in this shape to conform to the configurations of the frontand rear type bar segments 48 and 49.

Each of the type basket side arms 47 moves lose beside the bridges In) which are an integral part of the frame 1 and form the connections between the lower and toremost parts thereof with the yoke 51 at the rear. Portions of the upper surfaces of the bridges are faced at 52 to provide races for anti-friction bearings 53-carried by suitable containers 54 which rise from the side arms 47 with the general appearance of lugs.

A cover 55 (Fig. 1) keeps dust and dirt out of certain bell crank connections of the type bar system at the rear of the basket. Only one of these covers is shown imFig. l but there is another one like it (in actual practice) on the left side of the center of the machine. The cover is fastened down onthe yoke 51 by screws 56, and it includes a strong catch 57 which extends down and engages the under side of the adjacent bridge 50. The covers assist in holding the type basket to its bearings. i

A similar arrangei'ncnt oi anti-friction bearings occurs at the front of the type basket. Upwar-d extensions 58 (Fig. l) turnish bearing surfaces for the anti-friction bearings 59.- carried by forward extensions The upward extensions 58 have lugs ($1 at: the front and lugs (i2'at places adjacent to the type basket. The extensions (it) have stops 63 which movc be tween these lugs and so limit-the forward and rearward movements of the type basket.

Mention should also be made of the -fact that other parts of the type bar system at the front of the typewriter are protected by covers (54. In Fig. 1, one of these shown in place, the other being removed so as to reveal the location of such parts. T hcseare described below. A cover 65 protects the rear ends of the typewriter key levers, es pecially the places where they are pivoted on' the rod 35. v

Only one type bar is shown in each the type bar segments 48 and 49 inl+ig. 2, and this for simplicity in illustration. The respective type bars are designated 66 and 67 respectively. Each terminates in a head .68 and 69 respectively, the former having capital and small printing characters 70 71, 7 2 and 73, the latter-having small and capital type printing chara'cters74, 7 5, 76nd 77.

Taking these characters in- ,the order named, there are first, the capital ll and small h (To and T1) in roman style Next, the capital [1 and small l1 (7:3 and 73) in italic style. These occur in the front segments. In the rear segments, there are the small "p" and capital *1" (Tit and 75) in italic style, and small," p and capital *1 (7(3 and 77) in roman style.- The reader will have observed that both the order of the characters and their styles are reversed (reading down from the top) in" the two type segments.

This arran 'emc-nt or reversal of the order (it the printing characters and type. styles in the front and rear type bar segments is made necessary to acconumalatc the rearward movement of the printing platen 1:3 upon a case shift. The printing point is designated by the arrow 1 in Fig. 2. According to the present adjustment of the typewriter, a depression of the proper printing key will depress the type bar (it; and print the small h 71 in roman style (follow the heavy. dotted line 78).

lnder the same adjustment of the typewriter, the depression of another printing key will more the type bar 67 to print the small p 70 in roman style (follow the dotted line 75)). Should the operator now desire to print capitals or upper case letters 70 and T7 in roman style, the case shift key 11 must be depressed to mare the platen l2 rtaii-wardly so to shift the printing point to the place P. By following the light dotted lines 80 and Si respectively, the reader will see that the paths of the characters *ll" and 1 (7t) and 77) fall to the let't of the paths of the corresponding small characters, as is made necessary so that they may reach the new position of the and 4t), as'the printing paint I is shifted from the normal printing point I upon a case shift. In other words, the capital H 70 and the capital 1 77 are as far above and below the corres muding small letters 71 and 76 as the shifted printing point I" is from the printing point P. The identical principle )i'evails in ti 9 arran ement of the 1 i 1 "t 1 b t c ype s y e. u as characters in the ital printing in this styleinvolves shifting the type basket 7, the. description of the operas tion thereof is reserved to the place under the The Style Shift heading below.

The type bars in the respective front and rear segments 48 and 49 are mounted on pivots 82 and 83. A link 84, mi1nected at l the link so receives its motion through two (it, M

above the pivot 82 of the type her 66, produces a downward stroke of that type her upon a downward movement. The link 8-} llilSdliECi) connection with an appropriate one of the key levers A link 88 has it pivotal connection 8? with the type hair 67 at the rear of the machine null ut it point below the pivot 83, (1116i an upward movement of the link causes a (lownwurtl stroke of the type her to the printing: position.

Anticipating that promptness of return movement of the type bars 67 in. the rear segin'cnt i9 may he sacrificed by the pivotal connections of operating ports between the type bars 6? end the appropriate key levers, provision is made of :1 spring 9 each of the type bars in said rear segment. The spring 92 (there being one for each type bar inthe rear segment) is connected hetwcen a. crank extension 93 oi the hell crank 88 and a bracket 9% on the rear of the type basket 7. The tendency of this spring is to pull down on the bell crank 88, and by tram ing the connections, the reader will see that the ultimate tendency i; to push the type her 3? to the erect position.

Pads 9.3 and 96 in the front and. rear segments respectively, receive the return thrusts of the type our heads 68 mil t5?) and serve to rcilncc the sound of contact. These pulls are mounlcal on metal strips 9 end 98 which, in turn, may he made removable so that the pads may he replnccil when necessury. The type bar hemls are impelled hack to position against pads and 96 chiefly by the springs 30 (Fi e l} which operatencar pivotal hearings of key levers to re turn these levers to rest position.

Fingers 9i) and 100 guide the type bars .66 and (3? of the front and segments luring the downward anti upward strokes. These fingers are nothing more then nrcnzite metallic strips which divide tin. spaces hetwcen the type bars. To further gniile the type liars, insure on zihsolutel'. accurate printing impressinr 21ml pie wetions of the type hers, the pun on a-iuhstzin tinlly control, type her guide lot, is made.

As it is obviously impossible that a, similar place of engagement of the type her 66 in the front segment &8 may he made with the guide 101, said type her is :rovided with a key 162 at the upper extremity of the head 68 to serve the purpose under consideration.

The tyne bar guide 101 has the general shape of ii, as is to be seen in Fig. 5. But. in order to produce it more rapidly nerrowing passage than straight-sided i would provide, the inner edges of the guicle l 'll ere conrexly curved as shown. The guide has flanges 103 at the top for the puro'f fastening to the-adjacent side arms at? of the movable tyne basket 7. 'l he lower ends of the guide are connected by a bridge 10%, but this hriilge is so located as not to conflict either with the type bar 67 of the rest: segment or the key 192 of the front segment.

For the purpose of furnishing a complete description of the type our system, it is necessary to shy that the bell cranks 88 end 89 (Fig. '2) of the rear and front segments respectively, are divided into two sets of ten each. These bell crank. sets occupy pOSMlOIlS at the sides of the center of the machine (see Fig. 1). Of necessity, the various hell crank sets have hearings 105 and 166 respectively. The top conncctin links 90 cross the machine according to t 6 arrangement in 1, connecting corresponding hell crank sets of the two segments as diametrically opposite to each crank arms longer than others. it 1 :nccc. y to make them so in older that the links may cross as described. The foregoing description deals with a detail of construction of the typewriter, and. this has no particular hearing on other features of the cntion which are regarded as more important.

'il'ne style shift occurs when the type basket "I moved rez'irwarilly. The style of writinn; then changes from large roman to italic. All oi" the type hers in the two segments 48 enri itl'ltl ell connecting links and hell cranks move with the type basket 7 as a unit. The printing platen 12 remains where it unless the operator desires to print capital tiers, whereupon the case shift key-ll is depressed, as before.

-fill is sceoinplishcd either by cleprcssing the nyle shift key 107 or moving the ere-nit 108 Fig. 2) to the forward end of the nrcnnte slot 109. The first act furnishes mere temporary adjustment of he-type to the italic style which iuliustnient,

is s

remains only so long as the operator keeps rolon :(l mliustincnt of the typei mains until the crank 108 is turned back to the position now shown in Fig. 2.

' The first or temporary adjustment is made when the operator desires to interpolate in text written in large roman style, certain words, phrases, or portions of printed matter which it is desired to emphasize or offset from the rest of the text. The second adjustment is made when it is desired to write all of the text in italic style, and under such adjustment the style shift key 107 will function precisely as before, i. e. it will operate to temporarily reversely shift the type basket 7 so 't in large roman style in the italic style text.

Consider the construction A bar 110 rocks on the same pivot which supports the style shift bar (3; in fact, the rocker bar 110 may be considered an integral part of the bar 6. The rocker carries pendent links 111 and 112 at its ends. These terminate in hooks 113, 114 which partly embrace the lever 115 of the style'shift key 107.

- The style shift lever has shoulders 116 and 117 at the front and rear respectively, considering them in reference to the "perpendicular location of the. style shift bar 6. The hooks are connected by a link 118 which insures a parallel motion. Vi/hen assuming one position (as in Fig. 2)'of the rocker bar 110, the hook 114 lies in the path of the rear shoulder 117, while the hook 113 is out of the path of the front shoulder 11(3. Upon reversal of positions, the hook 113 will he in the path of the front shoulder 116 while the hooks 114 will be out of the path of the rear shoulder 117.

This change in position of the hooks-in reference to the shift lever shoulders determines whether the type basket 7 shall be shifted rearwardly or forwardly upon a depression of the style shift. key, 107. Take the adjustment as it. now is in Fig. 2: A depmssion of the stylishift key 107 will cause forward shoulder 116.

An operating bar 119 extends between the crank 108 and a bearing block 120 on the bottom of the frame. This block has a vertical slot ,121 so that the stud 122 of the bar may ride up and down when the crank 108 is turned from the rear end 1211 of the slot 109 to the front end 121. "This bar occupies space. between lugs 125 on the link 118, and it through engagen'ieut with one or the otherof these lugs that the hooks 113 at words, etc., may be interpolatedstyle.

and 114 are made to shift in respect to the style shift lever shoulders accordingly as the crank 108 is turned.

Turning or shifting the crank 108 changes the tension of the springs-12o and 127. These springs are connected between a disk 128 on the crank and the extremities of an are 129 which forms part of a bracket 130 carried by the rocker bar 110. \Vhen the crank 108 is in the reaward position, the spring 120 is expanded and the type basket 7 is held in. the forward position because the direction of the tension of the spring 126 is diagonally upward toward the left and under the pivot of the style shift bar 6. When the crank 108 is shifted forwardly, the spring l27 will be expanded and the type basket 7 will be held in the rearward position because the direction of, the tension of the spring 127 will be diagonally upward toward the right under the pivot of the bar 6.

It is therefore largely a matter of tension in one or the other of the springs 126 and 127 that determines the forward or-rearward position of the type basket 7. Obviously a depression of the style shift key 107 will act against such spring as is then under tension. For example, a depression of the'style shift key 107 under the present;

adjustment will rock the bar 110 counterclockwise and thus convey the lower right extremity of the are 129 farther toward the right.

This will increase the tension ofspring 120- and this increase of tension m0 serves .131 return the typebasket 7 to the originali'tosition when the key 107 is re leased. "lhe reverse operation occurs in re-' spect to the spring 127 and key 107 when the type tlasket 7 stands n a more permanently shifted position by virtue of changing the crank 108.

The type style indicator air-important part of the style shift apparatus, iii that it shows at a glance which of the two"ty pe styles are in printing position at any given time. The indicator is shown in position in Fig. l, and Fig. 4 shows it more in detail. The type basket 7 carries a plate 131 which has the legends 11a. Rom. 1312 and Italic 133 printed thereon. The former is the abbreviation for large roman and indicates one of the two styles of type. This plate,-

being a1iixed to the type basket, necessarily .moves back and forth with corresponding movements of the type basket.

Afiixed to an adjacent part of the bridge. I

,4 is a covering plate134. having an o emn'g- 135111 such a pos tion as to reveal cit er of. .the legends; referred to, 'accordmg t'o the position of the type basket. The operator uis only to glance at the covering pintet o see. whetherthe typewriter ishdjuswdfnl.

There are two of these segments, one at the front, the other at the rear. The rear. segment 4:9 l us type bars in which beta the order of the. characters and of the styles are reversed. 7- and. are the lower and upper case letters in itslic style, while 70 and 77 are the corresponding letters in roman style. This reversal of order and style is made ncccssz ry to reach the printing point elther in its original position l r shifted. position 1 To printlower case or small letters in roman style: the typewriter is used without changing any of the present adjustments in liig The operator depresses the shift levers 30 (Fig. 1) as in. any other typewriter. A dowrnvarl stroke of the typebar 6G (Fig. 2) will move the small character 71 along the dotted line 78 until the printing point P is reached. All other lower (use letters in large roman style and in the front segn'icnt elS will traverse a similar path. The letter 70 of the type bur i7 will traverse the pulh 70, and so will all other lower case letters in roman style in the rear segment 4%. None of the other letters represented will strike at the printing point under the present zuljustnient of the typewriter, us is poifectly obvious by referring to the dotted line position of the rear type liar (37.

To print upper case; letters inroinan style: press the ruse shift liey ll. This shifts the travel-way 14- (Fig. 2) against the heck stop 16 and shifts the printing' point on on the platen 12 corresponding distance. The shifting of the travel-way is ac C()lll1)llSllG(ll)3' the hell cranks l9 and 20 and link 22 in Fig. 3. Operate the key levers Sit us before. Either the upper case (immetcrs 70 (in the from segment 48) or 77 (in the rear segment 40) will now traverse the path 80 or 81 and reach the shifted printing point P. The reader should hear in mind that the printing platen l2 is moved in reference to the type ours in order to shift from lower case to upper character printing.

To ten'iporerily chun from large roman to italic style printing: tiis facility of the on adven e o only at the operator do res such times f.

terpolnte words, etc, in italic style in the roman style text which the typewriter is presumed to he printin The printing platen 12 remains where it is in Fig. 2 when the operator desires only to have the interpolated matter appear 1n lower case italic. For example, to print the lower case italic 73 depress the style shift key 107. The shift lever will (through the shoulder 117 and hook 114) rock the bar 6 to move the type basket 7 rearwnrdly until the pivot 82 assumes the position'a (Fig. 2) and the pivot 83 assumes the position b. A depression of the appropriate typewriter key will move the character 73 along dot and dash lines 136 until it reaches the printing point P. Similarly, the depression of' the aforesaid key will more the lower case italic letter Yd-in the rear-segment 49 along the dot and dash line 137 until it too reaches the printing point P. The aforesaid depression of the style shift key 107 is against the tension of the spring 126. -This spring already is under tension and is the medium whereby the type basket 7 is held in the forward position shown. The additional tension under which it is put upon depression. of the key 107 merely serves to return the type basket to the original position when the key 107 is released. i

To temporarily print capital italics while the machine is under adjustment for printing in roman style. press both the case shift key 11 and the style shift key 107. This shifts the printing platen 12 back to a position beneath the shifted printing point P. l t also shifts the type basket 7 until the pivots 82 and 83 assume the positions a and b. A depression of the appropriate key will more the upper case italic 72 along the dot and dash line 138 until it reaches the shifted printing point P, while the depression of the appropriate key of a. type bar in the rear segment will move the u .iper case italic 75 along the dot and dash l1ne 139 until it reaches the shifted printing point.

As long as both keys 11 and 107 remain depressed, the machine will write in upper case italic. Releasing. these keys will restore the printing platen 12 t0 the forward position and the ty e basket 7 to the forward position so that lower case writing in roman style may be resumed. To continuously print in italic style: the position of the crank 108 must be reversed until it assumes a position in the front end 2+3: of the circular slot 109. This change: the tension of the springs, putting the spring 1:27 under tension and relaxing the spring 126. This causes the style shift bar 6 to rock. so that the arm 8 changes its inclination toward the left and causes the type basket 1) engage the lugs 62. The printing n. 12 remains where The pivots lili) to more rearwa-rdly until the stops 63" 82 and 83 now permanently assume the positionsv/ and I), and by tracing the paths of the lower case italic letters along thelincs 1216 and 1217, the reader will see that nothing but small letter text \villappear at the printing point P.

The shifting of the crank 108 also shifts the positions of the hooks 113 and 114, the former now being under the shift lever shoulder 11.3. The hook 11-1 which was active in the preceding description, now assumes. a position to the right of the shoulder 11.7. and a depression of the style shift lever 115 will have no effect upon the hook 114.

To interpolate roman style printing in italic style text: it the operator desires to write one or more words in lower case roman style while the typewriter is adjusted for continuous italic style printing, the style shift lever 115 should be depressed to cause the type basket 17 to moveforwardly into its original position, as in Fig. '1. This is done against the further tension of the spring 127, and a release of the key 107 will cause the basket 7 to move back to its rearward position. The effect of the forward shifting of the type basket is'to perm-it printing of lower case characters 71 and 76 in roman style at the printing point P (follow lines 78sand 79).

To print upper case, letters in roman style while the machine is adjusted for continuous italic style printingz-depress both keys 107 and 11 at once.

I This again shifts the type basket.7 forwardly against the tension of spr-ing127, and shifts the printing platen 12 'rearwardly until it, comes under the shifted printing point P. By following the see dotted lines 80 or 81,:t he reader. wi]

' that the depression of the appropriate keys will carry the upper case roman style characters and 77 down to the printing point Pand thus interpolate upper case roman According to' the style printing in the italic style text, as long as pressure: remains on'the keys 107 and 11.

The reader now understands that the case shift key 11- is usedwhenever the operator desires to print upper case characters in either of the two stles, roman or italic. o'regoing description, pressure must be maintained on both keys 107 and 11 it the'interpolated upper case matter is to becontinuous' As this, under so necircumstances, might easily 'prove an arduous -tas k, provis1on is made of the shift lever lock-down -mechanism described in connection with Fig. 3. By the use of this meohanism the case shift lever 24 of the key '11 may .be'held down for a 'ressure on the key 107 to kee rolonged pe riod and the operator need on y to maintain the type asket'i' to the front. It can a so be seen,

by. having on the style shiftlever the same lock down construction as ison-thecase .1) the latch-39 is brought in position under the shoulder 40 and remains there by friction until the 'key is given a reverse motion to release it from said shoulder. While the construction and arrangement of the improvedtypewriter as herein described and claimed, is that of a generally preferred form, obviously modifications and '85' changes may be made without departing" from the spirit at the invention or the scope of the claims. i
