Application filed April 18, 1922,'Ser1a1 1T0. 555,885. Renewed Apri117, 1924.

This application. is a duplicate of my prior application #505,258 which was a renewal of application #324,643, which was a duplicate of application 250,380 which was a renewal of application 839,965, May 21, 1914.

This invention relates to a type wordwriting machine and it comprises:

First: A means for producing by the single depression of a key, and in some cases the depression of a shift key, whole words, groups of characters of any kind, and groups of small words or phases, with the spacing betweenisuch words, of all words and groups of characters in ordinary use.

Second: A means for producing all single characters by the depression of keys corresponding therewith, numerical and other characters being produced by the same keys.

Third: A means whereby two ke s "constitute-one in a compound key, there y lessening the number of independent single character keys, to thirteen.

Fourth: A means for automatically spacing the carriage a number of spaces corresponding with and one space more than the number of characters in a word, the said feed being a variable feed which actuates the carriage according to the length of any group of characters, and whichis also actuated by the depression of character keys.

Fifth: A means whereby 'a number of hammers are automatically operated also by the depression of a character key, the said number of hammers operated being equal to the number of characters in a designated word.

Sixth: Means whereby the carriage may .be moved forward immediately a designated number of spaces, the said movement being independent from the movement of a character key.

Seventh: An automatic end of a line, is returned from the end of each line to the beginning thereof, also means for returning the carriage mechanically from any positionit may occupy on a line, and a means for automatically feeding thepaper one or more line spaces, with the return of the/carriage to the beginning of a line;

construction whereby the carriage when 1t reaches the Eighth: A means whereby an ink ribbon is fed alternately in a forward and backwhich causes it to wind more upon the other reel and in the opposite direction, until entirely wound thereon; the operation being repeated with the continued movement of the carriage.

Ninth: A power mechanism operating mechanism of the machine; the said mechanism being set in operation bythe depression of a character key; and governed by a governor, and a means whereby an alignment lock, when in engagement with the type supports, and when having locked the same, causes the action of mechanism for impressing the type set, and the feeding of the carriage forward after such impression.

Tenth: A synchronizing mechanism for evenly. depressing transver 1e bars for simultaneously operating a plurality of-t-ype sup ports when the said bars are actuated by a character key.

Eleventh: A means for shifting transverse bars simultaneously and laterally across a type operating mechanism to change combinations of words.

In the figures A in'dicatesthe machine 'frame to which are pivoted at ,a type supports A (here shown in the form of wheels). Secured toeach type wheel A is a pinion a which is operated by a rack A which rack passes through a guide a at its lower end, and is held in position by a guide rod (1}. Thesaid rack A is pivoted by a pin a in a hole or lateral slot a each to a lever A, which lever is pivoted to a shaft (1, and continues as at A beneath the key .a solid bar, as at b". various heights, as shown in Figs; 1 and 22, the latter View showing a bar B depressed on to the frame A, which in said Fig. 23

blocks aresecured the levers 43 which converge into parallel lines to form the extensions A which connect loosely with the racks A and the carriage feed mechanism,

The outer blocks A may be provided with loosely i nwhich will be described later.

terlocking positions a, a for the purpose of facilitating the converging of the levers A Over" the levers A A is a key frame B forming guides b b and adapted to shift laterally across the said levers by means of rollers 5 having flanges 1).

Within the said frame B and arranged To the opposite end of each of these longitudinally andadapted to shift there with, are transverse bars B, which bars are provided with pins preferably threaded as at I)" (as clearly shown in Fig. 23), the

said bars B? being preferably shaped in cross section, having longltudinal flanges b I). and provided with a series of holes i b (Figs. 13 and 16)extending through both Fig. 51 indicates a type strip having char flanges. The holes in one of the said flanges of the bar B are threaded to receive for adjustment the threaded end I) of the pins 5 But the pins 6 may also be forced into These pins are set at is represented by dotted lines. It is thus seen that since each lever operates a type support, and that the degrees of depression imparted to a lever by operating through the mechanism leading to the type supports,

as described, will actuate said supports according to the depth or depths to which said levers may be depressed and move desiglid nated type corresponding to such depres- SIOIIS, into printing position. Fig. 22 represents a number of type operating levers, as shown by A, depressed to varying depths by the pins of the said transverse bars, and the even seating of the said bars which would cause a number of type corresponding with the depression of said levers, to move into printing position.

The transverse'bars B flareheld upward against an under edge bt'ofthe frame B, by means'of springs 0. bent over and held in position by a bar G which is secured at o to a plate 5* (see Figs. 1, 14 and 18), the said springs 0 being secured to the said plate 72*, as at 0 and projecting through the plate 5*, and in between and against the transverse barB to hold it 1n upward position.

These plates 6* also serve as guides to the ends 0" of the transverse bar B To each of the transverse bars B is attached a word key C by means of strips 0 which strips may be split and secured to each side of said bar, as at 0 0 or secured as at 0 or in any different manner. To insure the even depression of a bar, when a key may be located considerably at one side of the longitudlnal centre thereof, a synchronizing mechanism is employed, which consists of levers D, pivoted at (Z to projections d of the frame B. A connecting piece (Z connects pivotally at (Z (Z the two levers together. The opposite ends of the said levers support each a pin which passes loosely into a slot d". This construction is such that When any key at tached to a bar, is depressed and thereby depresses the transverse bar 13, by means of the slots (Z* in said bar and the pins in the levers D which fit into said slots, the lever nearest to the said key depressed upon the said bar, by means of its corresponding pin and slot, is actuated to move the bar (Z connecting the levers D together, and thereby simultaneously actuates the other lever D near the opposite end of the bar -B by means of its corresponding slot and pin, to move the bar evenly downother means than this may also be employed to the same end. The pins Z1 in thetransverse bars 13 are arranged equal distances apart corresponding with the distances the type operating levers are spaced apart. There are thirteen type operating levers here shown. (The number however may be increased or diminished). If a designated word contains a less number of characters than there are type operating levers, only as many pins are placed in the bar for the production of such word and to operate such levers, as there are characters in said Word. This is illustrated in Fig. 22. A key is provided with several words. The series of pins as shown in Fig. 22 represents the first word upon said key. For the second word to be produced by said key and its bar, a second series of pins (Z are arranged equal spaces apart, the said spaces corresponding to the spacing of the first series of pins, the first pin of the second series beginning next in order to the first pin of the first series, as shown in Fig. 1. The first pin of the third series (Z begins back of the first pin of the second series, and so on with as many series of pins (corresponding with the number of words upon a key) as there are spaces for said pins between each lever (the number here shown being ten series to a bar).

A means for simultaneously shifting the barsB for bringing one of the series of pins for the production of a designated word into position, is shown in Figs. .1, 7, 16 and 18, and consists of a number of stop or shift keys I), which keys pass through adjustable gauges d d preferably threaded and adustable in a portion of the key bed frame A These keys D? are provided With pins 03 which rest upon a portion of an angular lever D pivoted at at to the frame A or to the machine bed A. An opposite end D of the lever D is loosely connected by means of a slot and pin d, or other mechanism, to a portion of the rolling frame B which carries the transverse bars. A set screw D is made adjustable in said frame to limit the extreme lateral movement thereof against the frame A panother set Screw D corresponding therewith and at the opposite end of the frame B is made adjustable therein and against the frame A to limit the backward movement of the frame B and the transverse bars 13.

Each of the word keys C is provided with a number of words (Fig. 18) which are arranged in alphabetical order thereon, and are also arranged upon said keys under a designated initial character, as for instance the large character A upon the first word key, the said character A answering for all words beginning with A upon the imme diately following keys; the character B, upon the first of the keys having words beginning with B, and so on throughout the alphabet, a number of keys corresponding with the number of words ordinarily used beginning with a certain initial character being employed for words beginning with such initial character.

This arrangement is not essential to the proper working of the machine, as all words beginning with a certain initial character may be grouped together irrespective of the larger designations, A, B, C, D, &e. The words placed upon each key are arranged according to style of character, or background and position. Each word key is preferably divided by a dividing line C passing centrally across the face thereof, the first word on every key, as shown in Figs. 19 and 20, representing the arrangement, of words on two keys beginning with the initial character A, is here shpwn in a thintype on a white.

ground, the second position word on every key is a heavy character on a white ground, the third position word is a white character on a black ground, the fourth position word is a medium character on a shaded or tinted ground, and the fifth position word on every key is an open character on a lightly shaded ground. This arrangement of words according to style of character, and shade or tint of background may of course be varied as desired, or to facilitate manipulation.

The Words below the dividing line C on each key repeat the order and style of character and background of the words above the said line.

The shift keys D numbers 2, 3, 4 and 5 correspond in the style of character and background with the words occupying the second, third, fourth and fifth positions upon line of each key is practically in the sixth position withrelation to the operation of the machine, the arrangement of the words below the line and the shift keys corresponding therewith, being the same as the words above the line, the .order of the shift keys, for such words below the line, is simply repeated to facilitate operation, and the number 1 shift key is made to represent-the first word below the line, and so on with the remaining keys.

Between the keys C and made flush with or raised a little above the surface thereof, are placed dividing strips C which form between them cells for the reception and separation of the said keys C. These strips may be adjusted in any suitable manner to accommodate the said result, which is primarily to prevent accidental depression of other keys than the one containing the designated word or Words.

Running laterally across and beneath the transverse bars 13 is a piece E supporting strips or thin plates 6, Figs. 1 and 15,. which strips are arranged a sufficient distance apart to permit of the transverse b'ars passing loosely between them, the top edges 0 of the said strips being adapted to serve as rests or limits to the said transverse bars by the bottom edge of the latter resting thereon when depressed. This device is toprevent the undue springing of a bar whenidepressed by a key which is attached near its central portion.

Within the frame B are secured parallel guides F which are fitted with (preferably) threaded adjustable gauges F These gauges are provided with holes f through which extend key pins F which are in position immediately abovethe levers A. These keys. as shown in Fig. 21, are arranged from the shaft (1 over the said levers A to the pivot a They represent the single charac ter keys, and consist of a key within a key,

Figs. 24 and 25 sectionally illustrating the construction thereof. They are deprcssible to different depths according to their positions and corresponding with their designated characters, as limited by the auges F The construction employed in these keys is that of an outer key F having a depressed area f with a bevelled top edge f and a tube or sheath F Figs. 24, 25 and 26) extending therefrom and through the said gauges F Within the area f and below the surface of the key F is placed a smaller key F having preferably a convex surface F. From the key F extends a strip or pin f whichpasses loosely through the sheath or tube F and is in position above the levers A, A", its

bottom end being flush with the bottom end of the tube or sheath F struction of this device is that of employing A preferable con a thin strip for the inner key extension, and

between the transverse bars, though this is i not actually necessary. The lower ends of the extensions F and i may be bevelled in order that the two may be held together. In Fig. 24 is seen a spring f which'is of a weak construction and is designed to mere ly support the weight of the inner key in order to keep the lower ends of both stems even.

The gauges F are preferably tubular in construction with a reduced opening at theirlower ends, and within their said tubular portions, and around the sheaths or tubes F of the keys are placed spiral springs f which bear against the under part of the keys F to hold them .in upward normal position. Between the said keys are placed division strips F which form cells to receive and separate the said keys; the said strips being made flush with or raised above the surface of the said keys. The levers A} A are held even spacesapart on the shaft or pivot A which is held in position by supports F", by means of collars F which are adjustable preferably by means of screws 7, see Figs. 16 and 18. It will be seen, by referring to Fig. 18 that all of the vowels fall upon the inner keys, and that the consonants areplaced upon the outer keys, the arrangement of the type upon the supports, since the inner keys have a greater movement than the outer keys,

corresponds in'order with the arrangement with the characters upon said keys, the characters running in the order B A, D C, F E &c., the order of the type upon the type sup-'1 ports, Fig. 49, corresponding with the ar-'- rangement of characters upon the keys.

- If desired the order here shown may be so changed that the outer keys will have the vowels and the inner keys contain the consonants', thus causing the said letters to read in alphabetical order A to Z, when the type upon'the type supports would be arranged to correspond therewith, as shown in Figs. 53 and 54. Forthe production of numerals,

punctuation and other signs an extra type support (as shown in Fig. 50) may be provided, which support, fitted with such characters, shown in Fig. 51,-is journaled upon the shaft before and with the supports bearing the alphabetical characters.-

A support, A similar to that employed in the-operation of the other type supports,

Fig. 50, is employed to operate said first positioned support,.and a means is provided whereby the said support may be thrown into or out of operation- This means consists of a lever A which from its flexibility, or a hinge 9', may by any efficient means he swerved in one direction, to engage said first support, and disengage the second support, and if swerved in the other direction, disengage the first support and engage the second support, as shown in Figs. 50 and 55. A pin is secured to said leverA, which may pass alternately into a slot 9 of the first piece A or into a slot 9 of the second piece A This lever A" may be operated by means of a spring lever G secured thereto, which is provided with a finger push g,

- which finger push" is in frictional contact with a catch ,piece C, secured to a lever block A the said piece C being provided with nicks 9 into which nicks is adapted to movably fit a pointed or sharpened edge 9 of the lever G. It is thus seen that if the lever G is pushed and caught in forward position the lever A by means of its pin 9* will engage and operate the second support A which will operate the first support hearing letter characters. If the lever G is drawn backwards, the lever A, as described, will be thrown out of engagement with the said letter support mechanism A and will be thrown into engagement by means of the pin 9 and slot gt with the mechanism for operating the first support, which bears the numerical and other characters.

It is thus seen how the single character keys, shown in Fig. 18, since the arrangement of all characters upon such keys correspond with the arrangement of type upon the said supports, may produce, or may move into printing position, any of said characters that they may represent.

The transverse loarsB are preferably held from frictional contact with each other, and guided intheir downward movement by parallel strips B secured in the frame B, Fig. 14:.

Fig. 29 represents a modification of the type support, and consist of a strip H, having type it arranged longitudinally along one surface, and guided by guides 72 in front of a brace 72?, a rack )5, running longitudinally along the back of said strip. Each of the said strips H are operated by a cog wheel H which is pivoted upon a shaft 1* and operated by racks H which correspond with the racks A and operate upon pinions h secured to the said wheels H I do not limit myself to this construction shown, or to any construction to accomplish the end herein set forth, as I am aware that such construction can be modified in many ways to produce a similar result, it being needless to express more than suflicient to demonstrate the desired result attainable.

The feed employed in the operation of this machine is such that the mechanism will always produce one space more than the number of characters in a designated word set.

mama"? tion, iscapable of producing a movement equivalent to only the exact number of characters in a word, but it is desirable to have the machine automatically produce the space between the words. This construction is what I term a self differentiating feed device, since the said feed is diiferentially set by the difference in action as to the number of the type supports operating mechanisms upon the dogs of said feed, which causes them to be differentially set and consequently to make a different action upon the feed to move the carriage a different number of spaces according to the number of type set for a word. One manner of accomplishing this result is set forth in Figs. 2, 36, 44 and 45, in which the continuations A of the levers A are pointed as at 2' to operate upon feed set pieces I which are pivoted to small pins at i and which normally occupy a horizontal position when the levers A occupy a normal position. These pieces I are of graduated lengths and correspond in number with one space morethan the number of characters in a designated word. They are supported pivotally at i by a double lever l which is pivoted at i to a portion of the machine frame or bed. Below the pivot i is secured to the said levers a plate 1 which is provided with steps 5 corresponding with or one less than the number of pieces T, and back of the said piece I is a stop piece 2'" which limits the swing of the pieces I to a vertical position when actuated by the point 2' of the levers A A. The object of the plate I is to take the strain from the pivot 2' which is exerted upon the said pivot and the pieces I when the latter are set in vertical position to operate upon the edge I of the feed plate I when the said pieces I are actuated by the lever A The smallest of the pieces I, marked in Fig. 45 2' correspond with and is operated by the first position type operating lever. The second piece i corresponds with and is operated by the second lever. The third piece i is operated by the third lever. The fourth piece i is operated by the fourth lever. Having a pressure'upon' the lower plate T of the lever T is a spring I secured at i to a portion of the machine frame or bed. which spring has a set screw 1 bearing upon an extended end thereof, as a means for placing a tension upon said spring and lever l, to hold the latter in downward or normal position at the plate P. The before mentioned plate I which actuates the feed by means iof the construction "just described, is pro- 'vidcdhere with extended portions 1 j which pass through guides j 7' This plate is movable longitudinally in said guides and has secured to it a piece J which is pivotally connected with said plate at 7' The opposide end of said connecting plate J engages This same construction, with a slight altera pivotally at 7' with a. piece J 2 which is piv- J This cam or eccentric J is provided with a weight j, and frictionally engages when moving in one direction a clutch J which is secured to said shaft. The shaft J 3 is journaled in a portion of the machine frame A, and has secured thereto a cog wheel J which meshes with a rack J which is pivotally attached at y" to a portion of the carriage frame K. Supported by and loosely pivoted, upon the shaft J is another cog wheel J 8 of the same dimensions and kind as the cog wheel J These two cog wheels are placed adjacent to-each other, but the cog wheel J being. loosely supported by said shaft J is secured to and rotatable with a sleeve j to which sleeve is also securely fastened the friction wheel J (see Fig. 36 top view, and Fig. 37 sectional view).

The cog wheel J is secured on the shaft J and revolves therewith, to which shaft is also secured a drum'J", preferably having the flanges j". To this drum is secured a cord or other flexible strip j which is wound upon the said drum by the action of the feed in rotating the friction wheel, which action moves forward the rack J of the'carriage frame K by means of the c'og wheel J this forward movement of the rack, since the cog wheel J 6 also meshes therewith, and consequently moves with the cog wheel J revolves the drum J and winds, the cord j upon said drum thereby raising the -weight J until, when the carriagedias" reached the end-of a line, a portion 7a of the carriage frame K bears upon and moves forward a plate or bar 70 which is 'slidable in guides 72 of the machine frame A.' This part In is best illustrated in Fig. 38. It consists of a bar or rod, as stated, having an inv clined slot with elongated parallel ends Is into which slot loosely fits a pin is of a lever K, which leverlis secured to a pivot or shaft k", which has secured to it another lever K provided with a preferably short prong k and a. long prong k, which latter prong isiprovided inwardly with a spring 7.2 These prongs project one each side of the pivoted rack J, and the spring J? is placed in light contact with the side of the said rack nearest to the friction wheel J It is thus readily seen that if the feed actuates the wheel J 2 to move forward the rack J and consequently the carriage K, when the said carriage reaches the end of a line, the part k thereof will bear against and move longitudinally the bar is, which by means of the inclined slot and the pin 70 fittingtherein, will move the lever K, which in turn will move the lever K which by means of the spring 70 upon the prong is being caused to bear upon the "surface nearest to the friction wheel J 5 of the pivoted rack J,

will swing'the said rack upon its pivots y" away from and out of connection with the cog wheel J thus leaving it only in engagement with the bog wheel J (the limit of its movement being such-as to holdit in such position), when the weight J having been raised, revolves backward by means of its cord 9' and the drum J and the shaft J,

the cog wheel J", which, still meshing with the rack J", by the falling of said weight, carries the carriage back to its original position, at the beginning of a line, when the projection k* strikes against the oppositeend of the bar 7: which reverses the action of the levers K. and K and in the manner described, (though inversely) swings the rack J back to its original position, and in engagement with the cog wheel J i, this op- -eration being repeated with each movement of the carriage, back and forth. It is also readily seen that the bar is may be moved by the finger to cause the carriage to return to its original position at the beginning of a line from any position of its travel.

The carriage for carryingthe paper, as here shown, consists of the endsK which are held together by rods Ki and K To these rods is secured a plate K which is split longitudinally at the part 10 this split being directly in front of the space at which the type come to alignment for the production of a word. The rods K K slide loosely through bearing K in the machine frame. Depending from the said carriage is a metal sheath or tube K which is adapted to receive the paper, as-shown at Z, the said paper passing over the plate K and between the said plate and the type supports, and between a roller L which is pivoted at Z to a portion of the carriage frame, and a roller L which is pivoted as at Z to the carriage frame. To the end of, the roller L are secured preferably by means of a wheel L spurs Z spaced even distances apart. and of an even length. 'These spurs are adapted' with the backward IHOVQIHGllt of the carr1age, to glide against a curved angularly arranged strip L (Figs. 45, 46 and 47),

spurs. This strip L is pivoted as at Z, and

is preferably provided with a weight Z to hold it in one position, and a shoulder Z to limit its movement upon the pivot Z in one direction.

The object of a pivot to this strip is that the said strip may easily be mo ed out of its course to allow.it to freely escape the spurs Z with the forward movement ofthe 'carriage. The part L to,which the said strip L is pivoted is provided with slots Z Z, and is held movably in position by means of screws or pins Z Z, and a catch spring Z which has projections which fit into nicks 2 in the piece L; a knob or other projection Z is secured to the said piece to enable it to be moved to and from the pivot Z of the roll L. When the stripL is moved to a position as represented by the dotted lines L the spurs are able to glide upon its edge a distance sufficient only to revolve the roll L a distance corresponding with one space between writing lines, but when the strip L is in position toward the pivot Z the leverage of the spurs Z being diminished, in gliding against the strip L since the said strip then acts upon their pivot Z itcauses the said roll L to be revolved double the number of spaces, since the said spurs haye still to travel over the same surface but at a less leverage than required to travel when the strip L -is in the position L. To the pivot Z or to the spur wheel L is secured a lock wheel L, preferably provided with lock recesses and teeth Z with which is adapted to lock a lock or pawl L which is pivoted at Z and isprovided with a spring Z secured to a portion of said carriage, and having a tension upon the said pawl L to hold it in engagement with locks Z To the carriage frame is attached a rigid bar M running longitudinally across the front of the said carriage, and running longitudinally along said bar is a strip or sheath M having ends M which preferably pass each-side of the said bar M, and above the same, thereby forming a slot in which is placed a spring m secured by a pin m These springs exert a pressure upon the bar lM suflicientvto hold the strip or sheath in? in set position upon the said bar. Secured loosely to the strip or sheath M at M by, means of slots m and pins m are two racks M The teeth of the rack M are inclined in the direction of the forward movement of the carriage, and the teeth of the rack M are inclined in the reverse direction; Each of these racks are shorter in length than the length of the travel of the said carriage. and consequently do not act throughout the entire length of travel upon more than one of the ribbon feed reels, which longer action upon such reel is due to the position of the racks in relation to the said carriage. With these racks mesh ribbon reels M and M composed of a lower plate m wa secured to a hub m which is supported turnably upon pins m, the top plates 'm and m of the said reels are provided each with oppositely inclined teeth m? and m which mesh with their respective racks. The lower plates m m are preferably secured to the pin m which is loosely supported in the frame. The ribbon N is furnished wound upon a reel composed of thin plate on m secured to a hub m. From the said plate m projects a pin m and" through the said hub and plates is adapted to pass a pin m having a head m. This construction, bearing the ribbon N is adapted to beplaced between the upper m in the reel upper plate, and thereby holds said upper plate in rigid position. The pin m by means of the loop N formed at the end of the ribbon also fastens the said ribbon to the hub m The'ribbon is drawn from one reel and secured to the other reel with a wind in the opposite direction, as shown in Figs. 1 and 36. s

Fig. 36 shows the ribbon N unwound from the reel M and passing round a roll U pivoted at 0 and under a friction spring 0 said roll and spring being swivelled at O to a portion of the machine frame. The said ribbon passes from the roll 0 up over an inclined form 0 Figs. 1, 2 and 36, and around a form 0 across the front of the type wheels (the said ribbon being wider than the said type) and passing over similar forms adjacent to .the ribbon reel M and connecting therewith.

Since the sheath or strip M (Fig. 36) by means of the construction described may be shifted a space longitudinally on the bar M, which bar is secured to the carriage frame, and when so shifted will act on one reel and then on the other reel, as set forth, it is obvious that if the said strip M with its ratchets is shifted toward the right hand side of the carriage, when the said carriage travels backward along the line in operation, the teeth of the ratchet M will engage the teeth of the ribbon reel M and the teeth of the ratchet M will escape the teeth of the ribbon reel M. The forward travelling of the said carriage will operate upon the reels in the reverse'of the action just described, but since'the racks are shifted to the right hand end of the carriage the rack M being brought more into play with the ribbon reel M will have an action upon it greater than the action of the ratchet M upon the ribbon reel M, thus though the ribbon is wound from one reel upon the other reel and back again with the movement of the carriage, it is gradually wound upon the receiving reel, which is now M by the difference in the action of the racks upon saidreels; until the ribbon is almost entirely wound upon the reel M as shown in Figs. 1 and 36, when the double thickness N near the end of the ribbon N passing under the friction spring (Fig. 39 enlarged and detached view), the said spring ordinarily allowing only the single thickness of theribbon to pass freely under it. receives a tension from said spring which checks the free travelling and movement of its doubled portion N thereby causing a binding of the said ribbon N by means of its doubled thickness N passing under the said spring thereby causing'a binding of the ing the continued movement of the carriage,

which thus shifts the racks tothe left end of the carriage which causes then the lefthand rack to act longer upon'the left hand reel than" the right hand rack acts upon the right hand reel, thereby alternately making each reel the receiving reel. Figs. 1 and 36 illustrate the position of the ribbon and mechanism at the moment when the binding of the ribbon would cause a shift to the aforesaid racks. n

A power device consisting of a coiled spring preferably contained within a box or drum, as shown at P, Fig. 44, is used for the operation of the mechanism for causing imprint of characters and for feeding the .carriage'and ribbon. This spring operates upon a shaftp, to which shaft is pivoted a slotted cross head P having an extension lever P fitted therein which lever is provided with a limit 1) for its movement. Operated by said P and connected therewith, is a friction clutch or pawl 19 preferably pivoted as at 2 to operate upon a friction or toothed wheel p, secured to the shaft p for winding the said spring. A' pawl 37, secured to a portion of the machine frame A loosely engages a lock wheel p which holds the spring in wound position. The wheel P meshes with the pinion P which is secured to a cog wheel P (preferably being about five times the diameter of the pinion P the cog wheel P meshing with another pinion P which is preferably pivoted upon the shaft 17, and is secured to a cogwheel P which meshes with a pinion P" secured to a shaft 9. This gearing may ofcourse be arranged differently, but the object is, with one winding of the. spring, to store sufficient power to perform as much writing as is ordinarily done in a day. Tothe shaft 9 are securely attached and adjusted to revolve therewith, curved spurs Q which are preferably formed in the shape of disks, as shown in Figs. 2,7,44 and 56, and to the same shaft is attached a worm wheel Q, which meshes with a worm Q secured to a revoluble post 9 having governor arms 9 with preferably extension weights 9". Any other suitable power and governing mechanism may be employed.

To the end of the post 9 or worm Q is attached a head Q which is fitted and:

/ adapted to revolve inside of a portion of the machine frame designated 9 which portion is provided with an inclined face, high at g and, lower at a, a catch stop 9" (see Figs. 3, 4t. and M) is formed upon said face between the heights of Q5 and g which thus forms another step at 9 Within the head 9? is preferably formed a slot passing diametrically across-the same, within which is placed a catch bar 9, which is pivoted at g to the said head. A spring is fastened to the head as at g, and bears upon the said bar 9 to hold it in locked position. ,Adapt ed to raise or move the saidbar g to release itfrom the catch stop 9 is a piece 1". pivoted and formed preferably as at r, Fig. 6, and having a spring r bearingupon theheel r of the piece 7. This arrangement allows of a lateral movement to the saidpiece,

which piece, with the saidspring, is secured to a lever R, which lever is-pivoted movably to the shaft a in the manner previously described concerning other levers, the said lever B continuing as at R under the key board, and having an extending position R which passes immediately under and'has a contact with the edge of the transverse bars B This lever is pivoted atsr to another lever B pivoted to the shaft or pivot a and having an extending end B which also rests against the under edge of the transverse.

bars B The extended portion of these two levers form a straight edge in contact with said bars. Attached movably to one of the said levers, as at r is a connecting rod 1" which connects with a crank 1' tooperate a shaft 1"", which shaft passes laterally (Figs. 7 and 16) under the key bed, andconnects pivotally by means of cranks r with connecting pieces 1 which connect each movably with a bar or strip R pivoted at r, and extending parallel with and to the end of one of the single character. key support and guide pieces F. To the said bar R is loosely connected at 1- another lever R which extends parallel with the lever RF, and is pivoted at r to the key bed frame.

Levers R and R are similarly constructed and arranged and connected with the shaft 1' see Figs. 16 and 21. These levers R R, R and R are provided with different depths in steps, as shown at 1', r and 9, Fig. 21, the said steps being slightly raised above the gauges F, which limit the movement of the single character keys. By this means the single character keys, when about fully depressed, actuate the rod r and the catch 9 of the governor head Q To a crank on the shaft r is movably secured by meansof a pin and slot 8 a conwhose object is to cause a movement to the by the single depression of said key; the key head'tis secured to a strip T which may -be flexible, or may be provided with a hinge t and is fastened to a rocking bar t piv-' oted toa portion of the machine frame or bed. A piece T is formed as shown in-Flg.

17, preferably having the upright posts If and t. The top ends of these posts are above the lower edge of the flexible or hinged piece T. The said piece T is cut a varying-number of depths, as shown by the numerals, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Mechanism which will be immediately described, is connected to said key to impart a movement to the carriage correspondmg with the number of spaces in depth to which the saidkey isdepressed; for example: If the key is depressed until the lower edge of the piece T touches the part 1, the carriage will be moved forward one space, If the piece T is swerved to one side untll it touches the stop or post t and is then .de-

pressed, the number of spaces which the carriage will move will correspond with-the numeral and depth of space nearest thereto, as shown by 5. Intermediate steps indicate each a respective number of spaces. If the piece T is swerved over 6 and depressed, the carriage will move. six spaces, or if swerved to the post 25 and depressed, the carriage will move ten spaces. This construction of course may be arranged for any number of spaces. The shaft t con-. necting with the piece T of the key t passing from the ke board, bears a lever T connecting mova ly by means of a rod t with a bell crank 25, one of whose levers bears upon or connects with the ends t of a rod T which is provided with a spring '25 bearing against a collar 25 and a portion u of themachine frame. This spring It holds the rod T and piece T in normal position. Connectedpivotally to the rod T at u is a connecting rod u which engages movably at u with a part U pivoted to the shaft J; the said iece U bearing an eccentnic U. or other 0 utch to engage the friction wheel J and rotate the same when operated by the key 25. This clutch U when innormal position also serves to prevent the accidental backward movement of the carriage when operated by the machine, and the clutch J, Figs. 36 and 45 serves as a preventive for the accidental backward movement of the carriage when the same is moved forward by the key t. Placed in a parallel line opposite to the type supports are asmany hammers'or impressers V as there are type'supports. These hammers are provided with enlarged ends or heads '22. Figs. 2, 36 and 45, having projections e or having claws '0' adapted to' m'ovably hold hard rubber discs 11*, see Figs. 34 and 35. These hammers V preferably consist of straight bars held in parallel guides '0 and are provided with heels v and with springs 'v secured to the machine frame as at o and having a means a for adjusting the tension thereof. A finger key a) may be secured to said hammers to impart an impression by drawing the hammer back, thereby allowing it to strike against the paper to print or reprint an accidental missing or corrected type without operating the entire power. Bearing against heels of of each'of the said hammers, are bell cranks V pivoted as at 12 to a portion of the machine frame. These .cranks correspond in number with the number'of hammers. Movably secured to one lever of each of the said cranks are rods V which depend therefrom and are provided with feet shaped as shown at V which when the feed and hammer mechanism is in normal position and type operating levers are actuated by the depression of a key or From the ends of the levers V project at even distances pins 42 which have a loose engagement with and pass between the spurs of the spur wheels Q; and similarly projecting from the ends of the levers I bearing the feed set pieces I are pins o which pins are placed in said levers at a little greater distance from the pivot i than are the pills e in the' levers V from such pivot; the said pins '11 also passin between the spursof said spurwheels and having a frictional engagement therewith when the power is set in operation. Pivoted tothe machine frame at w is an arm or pendulum W which is provided with circularly arranged teeth '11) which mesh with simllar teeth to of an arm V which is pivoted at w and bears a cross bar or plate w and longitudinal ridges'w preferably V-shaped,- which when the type is set and the pendulum W swung pass into the nicks between the type upon the type supports and lock the same in alignment. To the 'p'vndulum W is attached an adjustable weight w, Fig. 2, and secured to the said pendulum is a spring actuated catch V which is adapted to loosely engage by means of its tooth a stay piece w. The said piece VV is provided with a lug 10' which when the pendulum WV is held in set position, is in position to be operated upon by a part w
