Application filed December 27, 1913. Serial No. 808.998.

To all 'w/mm, iii/lay concern.

lie it known thatI, KENNEDY DoUcAN, a

citizen of the United States, and residentof Minneapolis, in the county of l-lennepin and State of Minnesota, have invented certain new and useful Improvements in TypeJVriters, of which the following is aspecification.

This invention relates to typewritingmachines, and has for its object to provide a small and light machine. This object is attained by a construction which dispenses with keys, keyle\'ers, and type-bars, all of the type being carried by devices mounted upon the fingers of the operators hands.

In order thatthe invention may be fully understood, reference will now be made to the accmupanying drawings, in which:

Referring to Figs. 1 and 2: 1 is the base of a typewriting machine adapted for the practice of this invention. 2 is a cylindrical platen, having gudgeons rotatably mounted '5 inthe end pieces 3 of the carriage 3l. Preferably, the platen 2 is made hollow. Said carriage has for its base a flat rectangular plate 4 which is longitudinally slidable and is held down to the base and laterally 10 guided by undercut lugs (3 on the base 1 of the machine. Cut in one edge of the carriage base 4 is a rack 7 which engages a pinion S, which gears with a spur wheel 'engaged with a spiral spring 10 whose inner end is fixed to a bearing 12. Said spring is tensioned by drawing the carriage to the right, as in ordinary typewriters. The escapement for letter spacing comprises a pinion 13, engaged by rack T, a star-wheel ll fixed on the same shaft as pinion 1 aml a suitable detent 1(3 of known construction mounted on a vertically l'eciprocable rod 17, which is actuated by means presently described. -The carriage base. -l is supported by four anti-friction rollers 18, two .of

which are shown in Fig. 3, said rollers being'mounted on fixed shafts 1!) held by lugs 20 in the base 1.

The inking ribbon, 21, is preferably car- A ried by and upon the carriage 2- ll. Several constructions of this kind are possible. In the construction shown, said ribbon 21 is wonndupon a small reel 22 which is detachably mounted on one of the platengudgeons 5 between the carriage end part -5 ,fllltl the platen knob 23. Said knob is quickly detachable to permit removal of the reel 22 'and substitution of a fresh reel of ribbon. Said knob is held in place by a suitable spring latch, as 2 r, the free end ofwhich takesinto-av small hole in the knob stem Stem 25 and the correspomling hole through the knob 23 are square, so that when the platen is turned by thisknob no strain,will be placed upon the latch 24.

.The inner face of the reel 22 bears an annular series of ratchet teeth 26, engaged by a spring pawl 27 which prevents the reel tnrnadapted to pierce the ribbon. The ribbon is,

drawn moderately taut and pressed down 6 over said points 30, whereby it will be supported clear of the platen and about inch thereabove. This arrangement of the ribbon reel and;spring holder 2!) is so simple that it'reduces the size and cost of the machine materially and siinplilies the construe tion. But it will be understoodthat the invention is not limited to said device nor to its mechanical equivalents.

'hen the portion of the ribbon that extends across the platen becomes worn out, a fresh length is to be drawn from the reel and the worn portion is to be cut oll', the. fresh end of the ribbon being then attached to the tension device as aforesaid.

At each side of the printing center 31, a 1-ll)l)()ll5lll)l)tIl'tlllg device 32 is'providtal, which permits the ribbon to slide therethrongh when the carriage is shifted. As shown, said device comprises a pair of resilient lingers -32, mounted on lugs 1-32) on a bearing yoke ill. Said lingers 32 extend forwardly and are pri-ivided with slotted end portions 35 through which the ribbon is passed.

'The type,

ried by the operator's lingers and are struck down upon the ribbon 21 at the printing center 31, making their imprints upon a sheet of paper passed around the platen from the front of the machine. For drawing in and guiding a sheet of paper Fig. 2 shows a small friction-roller Ill) aml a curved sheet metal plate 37. Said roller is carried by bearings 38 integral with said plate. Said plate is roekably mounted on a non-rotatable rod'ild by means of lugs +0. The ends of said rod are held by the carriage end parts 3. Roller ill) is held pressed against the platen by torsion springs ll, one end of each of which is secured to a lug ll) on plate 37,

.the other end being secured to a collar 1;?

held in position on rod 35) by a set-screw l2 Means for turn ng the platen step by step for one, two, and three line spacing, areshown in Fig. l, but said means are no part of this invention and therefore are not described. There is also shown'a simple adjustable carriage-stop -l-l, foradjusting the width of the. margin at the left ol'the page.

For holding the bottom of a sheet of paper to the platen so that a line may be printed close to said bottom, the drawing shows a pair of lingers ll), both of which are mounted on a. rock-shaft l7, journaled in the carriage ends 3. Said lingers are pressed against the platen by a spring 48, acting on a. pin ltl projecting from said rock-shaft. By depressing a linger-pitate 50 on said rock- 'shaft,.the lingers ll) may be retracted from the platen to permit a sheet of paper to be passed around the platen from below upward, if so desired. ()rdinarily a sheet of paper will be lirst passed under the. lingers 4t) and back to the roller 3t); then a turn of the platen will feed the paper. in to the position to receive a date line or a lirst line of print.

Coming now to the printing means: The

hereinafter desrrilwthare ca rforms of printing means which are described first herein, are not necessarily the best forms'fin practice, as compared with other iorms which are also hereinafter described,

but are first described for the reason that they coact with the type-guide shown in .Fig. 1.

In'Figs. 8, 9, and 10, the type, as the characters will herein be termed, are formed upon one or more sides ot'a thin, rectangular, preferably square block 5. which may be of any sutliciently hard or tough material. Where three sides of such block are provided with type, the lower case characters h are placed on the intermediate side as shown; and the capitals, numerals and. miscellaneons characters on "the adjacent sides. Regarding the number of characters to the side, an odd number is preferable in the present instance, and in order to pro Vide a small and light block it is thought that five characters per side are sutiicient. The above described form of type block is to be attached to a finger of the hand, or of a glove, by any suitable device. Portions ot' such devices are shown in Figs. 13, 17 and 18.

In the structure shown by Figs. 9 and 101 a pair of very thin sheet metal ears 56 are provided with a pair of opposed studs .39

which project both inwardly and outwardly.

'Ilhe inwardlv projecting portions 5 take into a centrally positioned opening in the block 54. The ears 56 are resilient. and exert inward pressure on said block. \Vhen removed from the block by being sprung outwardly they will spring back to their normal relative position.

A slight rocking motion of the, ty 'ie block upon the stud ends 5!) may be provided for by any suitable means. Asshown in Figs. 9 and 10, a small pin 57 is fixed in the type block with its ends projecting slightly. lo receive said projecting ends a short slot 58 is punched in each of the. ears 5G. The advantage of this device will be hereinafter stated. Fig. 11 shows another means'to the same end. In this'device the cars 56 have a slight play between lugs 35, the studs 5?) being the pivots of the motion.

The. outer stud ends 59 are preferably round in cross-section, and their function is to enable the operator to accurately register the selected typewith] the printing center 31. As it would be inconvenient for the operator to bring the type carriers into a position at right angles to the longitudinal axis of the 'ilatcn. there are two type guides .provided, and wlnch cross each other at right 'angles both centering over 'the same point on the platen. The type carrierson one hand are struck into one of these type? carrier guides, and those on the othor'hand into the other guide. 7

The type guide' shown in Figs. 1 and 2 consists of a sheet metal device having in its-impet taco two intersecting grooves, R and'L, whose intersection is directly above the printing center 31. Each of said grooves is formed by two-pairs of walls (31, whose upper portions are flared apart as shown. andwhose lower portions are spaced apart the proper distance to receive and lit loosely a type block 5% or the lower portion. of a type block. All the walls (31 are'secured to a base plate (52, and some of said walls may be integral with said plate. Intersecting slots registering with grooves R and L are cut through the base plate '62, to permit passage of the type blocks therethrough in any position. Cut in the upper portion'ot each wall (31 are a series of notches (it; of which there are four pairs-tor each groove R, L, said notches being adapted to receive the studsSJ, guide the type block longitudinally, and permit full depression of such block between the walls (31. Said studs are made of a diameter equal to the thickness of a type block, in order that thewalls (31 shall serve as guides for said studs when themiddle character of any row of characters is to be printed, for example E -in Fig. 8. In other words, the walls 31 then'iselves will serve the same purpose as'ifsaid walls were unbroken by the grooves R, L and had centrally positioned guiding notches for the studs 59. As'clearly shown in Fig. l, the type guide G1-62 has provision tor guiding a type block in five positions, regardless of whether the type-block be inserted in its normal position (intermediate side down) or as shown in Fig. 17, or 18. The guiding groove marked R is appropriated to the use ottype blocks carried by the right hand, and the cross groove marked L is apj'n-opriated to those carried by the left hand. The angles at which said grooves extend are such that the operators lingers may be held in easy, natural positions while operating, this-being of course conducive to speed.

\Vhen printing the characters most trequently used, the type block is simply held in the vertical position shown in Fig. 9 and depressed. \Vhen printing from the other sides ot the type block. the type carrier is to be held as shown in Fig. 17 or Fig. 18 and depressed.

In order that the carriage shall be automatically stopped for each character printed, the type-guide. may be mounted for vertical movement, or, the same result may be efl'eeted with a stationary guide where other (34 in whose ends are. conical holes (not shown) into which project the conical ends of set screws (39 which pass through the arms of bearing yoke, 84. Inte ral with portion M is a depending lug 67, which is urged forwardly by a spring 8 secured to a crossbar (39. Fig. 1 The guide (31-432 is thereby held yieldingly in a position above that to which it is depressed when a character is struck. The downw .rd movement of said guide is adjustably limited by a stop 70, Fig. 1', which is shown as an eccentrically fUFllittl lug 79 on a roekable transverse bar 71,whose ends are journaled in -the yoke arms 31. Said stop is turned by means of a lever 7:2, and is lixed in adjusted position by a jamnut 72- on thethreaded portion 74. The up motion of the guide til-tt2 is limited by a stop 76. which is shown as integral with the yoke 34. The eseapement connecting rod 17 extends up through a guiding hole in the base 1 and is pivotally connected to the arm lit by a pin or its equivalent, 77. -\Yhen the guide (El-(3; is fully depressed. arm (A depresses rod 17 which causes detent 113 to shift. but notto release the star wheel 14. When the guide (H 2 asceuds. rod 17 lifts thedetent it) which in so moving permits the star-wheel to be turned one point by spring 19. the star-wheel being then arrested by the detent. as is well understood. Said motion of the star-wheel l lpermits rotary motion of pinions 1F). and hence a leftward step of the carriage, to position the paper for the next character.

The forward portion 7h of the guide base (r2 may be suitably formed. as shown or otherwise. to provide a spacing ke v.' This key may be struck by the thumb of either hand, without shifting the hand from its usual operating position.

The guide il--92 and the members that are integral therewith will be made as light in weight as consistent. in order to reduce the inertia thereof as much as possible.

In using a plane sided type block, in practice, the block is likely to descend in the guide at an incorrect angle, thereby causing an uneven impression to be made upon the paper. Mechanical means have been devised which will automatically alinev the typeblock in this respect. just before the type strikes the paper. simple form of such means comprises sho ilders 79 on each type block, whereby a plain block becomes as shown in l igs. 9 and 1t). Said shoulders slightly from the sides of the block and. are parallel and close to the periphery thereof on the three type-bearing sides. For coaction with these shoulders, the inner faces of the guide-walls ()1 are formed with narrow seats 80 uponwhich the shoulders 79 are to be seated, as shown in Fig. 5. Said should'ers are not visible in Fig. 2, as their upper surfaces are in the same plane as the upper surface of the base plate- 62. .TVhen av type block is pressed down into groove R or L, it

' the seats 80 in the guide walls 61.

-vided with a pair of sheet metal crator places the 79 project.

will be automatically. alined by the pressure of the finger upon the carrier, causing the shoulders 79 to seat thelr full length upon grooves R, L being oblique to a line of writing, the type must of course be set obliquely upon the blocks as is shown by Fig. 8.

Beforedescribing any specific finger-attaelnnentdevices, the modified forms =of type-blocks shown in Figs. 12, 13, 14 and 17 will be briefly described.

'lhe-bloek shown in Fig. 12, is made with the guide-studs S1 integral therewith or tightly, fitted in an axial hole therein, instead of said studs being held as in Fig. 10.

Fig. 13 shows a type-block. 81 which is' made lrollow, with stiffening ribs 8%, and at one side with a heavyportion S-t" ilito which the stem 55 of a finger clip is screwed. 7

Figs. 1} and 15 show a type-block 86 proside plates ST-sccured thereto by rivets 88. Each of said plates is formed with three two pronged forks, 89, one for each printing face of the block. Figslti is a plan view of a guide which is adapted to coact with-this form of type block. This guide is or may be exactly similar to that shown in Fig. 1, with the e \ception that the spaced tongues 90 between the notches 91- are positioned'to guide the forkshtl in adjusting the block for. different characters. This is to say; the 0pfoidts S9 astride of the proper pair of tongues 90 whereby the typeblock is longitudinally adjusted, then depresses the type block as usual, either vertically or in the manner shown by Fig. 17 or 15. Obviously the guide grooves R, L must be unobstructed, in order that they may receive the type-blocks in any position.

So, in order to provide substitutes for-the tongues 90 that must be omitted on account of this fact, the guide walls 92 are cut away as shown at 93, sufliciently to receive the forks 89 between them when a middle character is to be printed.

The finger attachment device shown in Figs. 17 and 1b and partly in Fig. 9 is made of a single piece of very thin metal, excepting the studs 59. Said piece comprises the.

aforesaid ears 513, a flat portion 91 connect-- ing said ears, upwardly turned finger cli s 96, 97 and two pairs of ears 98 which ho d the finger-tip in place. One or both of said clips9t' 97 are provided with suitably posi tioned cars 99 which aid in holding the devicein proper position upon the finger. The clips 96, 97 may engage the sides of the finger, but preferably they engage its front and back, asshown. In Fig. 13',tl1e finger tip cup 100 is provided with ears 101 to which any desired form of finger clips may be attached.

The'type blocks may berotatably mounted, whereby the type carriers may always be Tli'e said depressed in one A rotatable type.

block is illustrated in Figs. 19 and 20. The type block 102 is of the same form and has the same arrangement of type as that already described. The studs 103 may be rotatable in: the ears 104, and fixed in the block 102, r vice vei'sa. (See Fig. 10)., A

- spring detent l is provided for holding the'block temporarily at any of the three printing angles. As shown, the. detent is integral with one of the resilient sheet metal ears 104. Three indentations 100 are made in'the block, to receive the detent in their ns type block is to be turned when necessary by spective positions of the type block.

' pushing any corner thereof against any conrows of type but is ofsinaller dimensions venient fixed portion of the machine (see Fig. 1). or against the tabe upon which said machine rests; thereby imparting one or vanore quarter-turns to the type block, ac-

cording to circumstances. The cl'iaracters Ii. of most frequent occurrence, are placed upon the intermediate side of the block. I

' In Figs. 21 and 22 isshown a tormof type-block which is. provided withv three than that heretofore described and is pi votally mounted to turn about an axis that is parallel to the row of type. The type block carrier consists of a sheet-metal yoke 107 .108 in whose ends 108 the gudgeons 109 of thetype block 110 are j ournaled. One gudgeoii 109 is extended to rece ve a very small pinion 111. .Said pinion is engaged by a segment gear 112 on the end of a lever 113 having opposed lever-arms 114. band lever is. pivoted on a pin 116 and is held yieldingly in acentral position by a spring 117. Spring 117 as shown is a lcat spring, and is secured to the cross member 107 of the yoke by a rivet 118. The free end of the spring passes through a slot in the adjacent yoke portion 108 and the extreme end of the spring presses down upon a flat surface of the gear lever-.113 between arms 114, holding said lever, pinion 11.1 and type block 110 at normal position, in which position the type block 110. will stand squarely, with the row of type it most often used at the bottom thereof. The yoke ends 108 are provided with guide- lugs 121, 223. In the guide walls 123 are suitable receiving grooves, 122. Said grooves'are spaced the distance from center to center of the type. in a row, and are upwardly flared, as shown in Fig. 47, to facilitate the insertion of the guiding parts on the type yoke 107-108. The notcbcs122 are preferably positioned in the four interior corners of the guide 123. These notches122 receive lugs 121 or 223 on the yoke ends 108 when the type carrier is in extreme positionin either groove R, L, and thereby assist in holding the type block in ahnement. 'lho guide-walls 123 are set in pairs to form two intersecting grooves, and are spaced at such' a distance apart as to permit the type block In order that the type block shall. be

caused to turn to present either lateral row of type downward, for printing, two pairs of shift plates 124, 125,126, 127, are provided, one pair for each pair of guide walls Each of said shift plates is formed with high portions 128 alternatingwvith re-. cesses 129, said high portions being spaced the same as are the guide grooves 122, there being a high portion and a recess for each character in a row on the type block. Each shift plate-is mounted movably, whereby either a high 128 or a low 129 may be positioned directly below one of the lever arms on the type carrier. As shown, each shift plate is attached to its guide wall 123 by two screws 130 which pass through a longitudr Normally all'four of the shift plates are in iiioperative position, that is, their lows 129 are beneath the. lever arms 114 in anyposition oithe type block in either groove R or L, said recesses being deep enough to permit a full depression of the t ype block without actuating, either of the lever arms. Any

suitable mechanism for shifting the. shiftplates when necessary, may be :employcd.

Such mechanism must either shift each plate independently, or one plate of each pair-simultaneously. In Figs. 24 and 25 a very simple mechanism is shown by which the last named mode of shifting is effected. A cam ring 132 is rotatably mounted upon grooves in the" end walls 133 of the type block guide. Upon the. upper face of said ring are four cams 134, 135, 130 and 137.

Each cam in the form of a narrow tongue,

having preferably a curvature to reducefriction of operation. shift-plate 125 has an Referring to Fig. 22, extension 138 in-the bottom-ofwhich is a cam-notch, 139 thro igh which the cam 13:) is adapted to pass. 1 Each -of the other shift plates is idei'itical in construction, and said plates are shit'table in like manner by the other three cams 134, 136, 137, respectively. It istliought the showing in Fig. 23 will suffice for all the parts.

just mentioned. Fig. shows all four cams in their normal position, in' which one end of each is just entered in its notch. If the cam ring 132 be turned clock-wise, cams 134 and 130 Will move shift-plates'1'24 and 126 inwardly, while the other two cams 135 and 137 will recede from their shift-plates without moving them. By turning the cam ring back to normal, shift plates 124 and 126 are replaced in normal position. If the cam ring be turned counter-clockwise from normal position, cams 135 and 137 will move shift-plates 125 and 127inwardly, hil th other two shift plates will be unaffected. The reverse movement of the cam ring will restore the shift plates 125 and 127 to normal. The cam ring is provided with an arc.

late 144 provides a spacer-key, correspondmg to the part 78 shown in Fig. 1. Pinion shaft 143 is journaled in the .base 146 and has keyed thereon an arm 147 to which is connected a tension spring 148 which normally holds the pinion 142, cam rin 132, cams, and shift plates, in normal positions. For turnin the shaft 143, any suitable means may fie provided. As shown in Figs. 24 and 25 there is a shift-bar, 149-149, eX- tendin right and left from the shaft 143. Said s ift-bar is pivoted in bearings 150 and acts on shaft143 through bevel gears 151, 152, 153, 154. Depressing the front side of either half of the shift-bar will turn the parts in one direction, and depressing the rear side of said shift-bar will turn the parts in the opposite direction. The parts referred to will be automatically returned to normal by the spring 148. The pinion 142 is sufficiently lengthened below the gear 140 to retain its enga 'elnent with said, gear .when the type bloc guide is depressed by the operator for the purpose hereinbcfore stated.v I When anormal character is to be printed,

the operator inserts the guide lugs 121 in the proper pair of grooves 122 and depresses the type-carrier until the type strikes the paper through the ribbon 156. Both of the leverarms 114, will pass down into re cesses 129 and willnot be turned,- hence the type block 110 will not be turned. Now supose that the next character to be printed lies on a lateral side of a type block on the operators right hand, and that the type block must be turned to the ri ht in order to print said; character. With t e left thumb the operator actuates shift bar 149 in the pro er direction, and inserts the type block e groove R in the correct longitudinal position. Said movement of the shift bar 149 causes cam 134 to shift plate 124 inwardly, whereby the highs 128 of said plate will be placed inthe positions normally oc cupied by the lows 129. Now when the type carrier is depressed, the left hand lever-arm 114 (seen as at the right in Fig. 22) will be forced upwardly by one of said highs 12%, whereby the pinion 111 and type-block lli) will be turned to the right. the latter receiving just a. quarter-tun beforedts rotary mo.- tion is stopped by a tag 156 on gearl'l2,

The operation of the shift-plate having been fully described for one character, "its use for any character will now be readily understood.

The form of type carrier and type block guide, shown in Figs. 21 and 22, may of course be embodied in a machine like the machine shown in Figs. 1 and 2.

Certain modified printing means are shown in F i s. 26.to 29, inclusive, and will now be brie y described.

Figs. 26 and 27 are a sectional side view and a top view of a one-fingertype carrier in which a pluralityof type blocks are carried. The remaining. figures illustrate various forms of type block guides and selecting devices with which a machine must be provided in order to utilize these forms of type carriers. In Fig. 26 and Fig. 27, the finger clip is one piece of sheet metal. liigidly mounted thereon are six pairs 0! aws 157, and pivoted in each pair of jaws is a type-block 158. Each type block bears two type 159, one on each end. These type blocks are free to turn 90 degrees ineither. direction, but normally each block is held in a transverse intermediate position (as shown) by a spring. One form of spring for the purpose is shown at 160, Fig. 28.

161 on the type block 158. form of guide for these type blocks is illustrated in Figs. 30 and '31. consists of a square tube" 162 havin four upwardly flaring walls'163. In the ottom of the guide is a reduced square opening 164. The diameter of the larger )assa equals the width of the jaws 151, while i the diameteinof the reduced opening 164 equals that of the type block 158 itself. In selecting theM-haracter to be printed, the operator strikes the end of the type block that is to beturncd up, against one of the flaring \val'lsl63. and pushes down, thereby lowering the proper end of the type bloc into the passage 165, through the guide opening 164. onto the receiving surface (ribbon or paper). l' i'ion removal of the carrier the. type block is returned to normal b its spring 160. This guide 162-163 wil answer for the type blocks carried by both hands. as will be readily understood by- This guide f 11'.

w cor? to be struck, maybe obviated by providing a guide that is capable of rotary movement.

Such a guide is illustrated in Figs. 3:2 to 38 inclusive. In this guide the walls 166' are "only slightly flared. In two ad acent walls are out two recesses '1', Z, wlnch permit one end of a type block to descend therein,1thedegrees therefrom. WVhen said recesses are pointed towardthe'operator, that end of a type block nearest'the operator will be depressed, but should the guide be turned 180 degrees,,the opposite end of the type block-- would be depressed, and a different character be printed. On the guide piece 166 are an annularflange 167 and a'rin of pinion teeth 168. A plate-169' (Fig. 36 "has a circular opening which loosely fits in the annulargroove 170 and supportsthe guide. A rack 171 is mounted slidably on'plate 169 and en gagesthe pinion teeth 168. Said rack is capableof turning the guide 180 degrees, and is provided with finger-pieces 172,; 17 3',

by whichitnmy easily be actuated. A stop' 171 on the rack limits its travel in'one' direction by striking, a stop 176 on the bottonrof One finger piece 173 limits the plate 169. opposite travel by striking the side of'plate 169.- The rack is supported by a piece 177 (Fig. 38) tlnrough which screws 178 pass into a piece 179 on the upper side of said plate. The rack 171 is manipulated according to the positions of the types that are used, some types requiring a turn. of the guide 166 and others not requiring such movement.

Fig. 39 shows a curved gear 180 for turning the type block guide. Saidgear-is actuated by manipulating the finger-piece 181. A n equivalent effect may be obtained by employing duplicate type block guides, with means for moving either one of them to the printing position. As shown by Figs. -10 and 41,.tw0 type block guides 186, 187 are rigidly mounted on an angle-lever 188 which is fixedly mounted on a vertical rockshaft 189 having bearings 190 on a post .191. In one of said guides the recesses r and I face the operator, but .when the other guide 187 is brought into positionvfor use its'recesses 1- and l are oppositely disposed.

Fixedly mounted on the" shaft 189 is a grooved pulley 192, to the periphery of which the ends of two cords 193,191 are fastened, cord 193 being fastened to a pin 196, and cord 191 to a pin 197. Said cords are partly wound upon the pulley and-in the same direction, and the winding is performed by a torsion spring 198 which also holds theangle-lever 188 in the position shown, against a stop 199, in which'positi'on of the lever the guide 186' is in-op'erativerelation to-the platen,200. 'To cause an ator pulls on either cor-d193, 19-1, thereby the guide 187 in operative position. Ae

soon as the character has been printed the cord is released, and the spring 198 restores the other guide to operative position.

arranging the more frequently used charal this guide to the other may be tqfuded to 3 Instead of mounting the type carriers directly upon the fingers, theta/QB the glove being shown. This is what would be termed a skeleton glove, as unnecessary "ters to be operated 1n"the'nornially' qtloned guide 186, the numberofshifts 'rom 1 @arriersh v i 7 .may be permanently attaches to gloves. one of which'is shown by Fig. 4-"), the back of portions thereof'are cut away in order that" the, hand may be cooler and its fingersh'ave freer play. The knuckle band 203 is con nectedflwith the wristband 201 by two or more narrowj strips 206. The ends of the fingers are cut away on the back, as shown at 20. The inner. sides of the glove fingers '208, are left full length or nearly so, forming tags 209 and the type carriers are fas-' tened to said tags in any suitable manner..

One device forthis by Fig. 44, in which kind is indicated.

purpose is represented a type carrier of any A slot 210 is punche' side of the finger. The tag 209 of the glove inga type-carrier when the latter is, not in.

use and alsoto facilitate the placing, of the type carriers upon the fingers. Of course there 'will be as many of these stalls as there are type carriers, but the illustration of one will suffice for alfl. i 5

Fig. 15 is an elevation, facing the opera .tor, and Fig. 16 is a top view, in which the 'POSIIZIOII of a type carrier like that shown in Fig. 22 is indicated by dotted lines, being the type block. 114' the levenarms. pair of opposed springs 213 have a common base 21-1. which is secured to any horizontal surface by screws Q15. Springs 1213 converge rearwardly and at their free ends are f bent outwardly. forming inclined shoulders" 221. The height of springs 213 is about that of the guide lugs 121 (Fig. 22) which lugs the shoulders 221 are adapted to engage. Adjacentthe free end of each spring 213 is an upright spring 216, having a. foot 217, secured to the surface above mentioned,

100 throughthe clip 211 that engages the inner by screws 218. Each spring 216 is formed with an inwardly facing shoulder 219, and with a lip 220 extending upwardly from said shoulder. Said shoulders are so spaced as to receive between them and hold down the lever arms 11s when the type carrier is fully depressed. One of the springs 216 is provided with a lug 222.

The operation will be as follows: the type carriers, being in their stalls, are placed on the fingers by inserting the fingers down-- which is a longitudinal undercut groove 226.

227 are two type block turning members, one for each hand. These members extend across the pad and are sufiiciently high to engage and actuate the lever arms 11 1 of the species of type block shown in Fig. 22. Each member 227, is provided with a foot 228 which slidably fits in the groove 226. thumb-screw 229 is threaded through the foot 228, and by pressing upon the groove, binds the member 227 any desired pointv along said groove.

To ink the type of a type block of the species shown in Figs. 9, 11, 12, or 19, it is only necessary type block of the kind shown in Fig. 22, the lateral type rows are inked as follows: to ink the right hand lateral. row of type, the type block is placed at the right of one of the members 227, and the lever arm114 adjacent said member is pressed downupon said member, by depressing the finger clip 11:). Thus the type block 110 will be turned in the proper direction to bringthe desired row of type down upon the pad. Tolink the other lateral row of type, the type block is placed at the other side of the member 22 and theother lever arm 114 pressed down thereagainst. The forward portions ofthe members 227 serve as guides for holding the type carriers from turning on the fingers during the inking operation. The members 227 ,are made slidable so that they may be moved .toa freshportion of the pad when the ink becomes scant on the portions of the pad adjacent them. This pad may be mounted upon the base of a typewriting machine, if so desired.
