SPECIFICATION forming part of Letters Patent No. 466,490, dated January 5, 1892.
Application filed October 10, 1896. 1 Serial No. 367,751. (No model.)
To all whom it may concern:
Be it known. that I, GEORGE M. EoKELs, a citizen of theUnited States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Type-Writing Machines, of which the following is a'specification.
The object of my invention is to provide a type-writing machine by means of which more than one character in the proper consecutive order, with requisite spaces between letters: and-words, may be printedupon the paper by; simultaneous pressure upon the keys which:
produce the character-sand spaces.
To this end my invention consists, prima-' rily, in providing for the character, more than one key, pressure upon either .of which shall produce theimprint of the same character; further, in mechanism wherobythe different keys for the same character cause the letter to be imprinted in different orderwith relation to the other letter or letters produced by simultaneous pressure upon other keys; and it consists, furthermore, in the general .mechcanism and various details of construction and combinations of parts whereby is carried into effect.
In the drawings, Figure .1 is a topplan view ofthe machine with a part broken away for purposes of illustration; Fig; 2,a view of the my invention same in side elevation; Fig.3, a brok'enpen' spective view of the back of the device and showing only certain of the details; Fig. 4, a perspective view of apart of the mechanism removed from the frame and placed in'oper ative relation, some of the details shown being indicated in part, where: hidden, by dotted lines, and another detail being partly broken away for purposes of illustration; Fig. 5, a-
broken perspective view of the same character as the last and illustrating some of the same and other details of the construction; Fig. 6, a plan view of the key-board; Fig. 7, a broken perspective view of a detail of the spacing mechanism; Fig. 8, a view in eleva-' tion of a wheel provided on its perimeter with type, hereinafter designated as the first-podesignated, respectively, as second and -1liof Fig. 9. andviewed in the direction of the arrows; Fig. 12,'a'top-' 'planview of the type wheel and segments; Fig. 13, a section taken on linei.13.13 of Fig. 16 and viewed in the direction of the arrows; Fig. 14, a section taken -on'line 14.14 'ofFig. 15, and viewed in the direction of the arrows; Fig. 15, a view in elevation of the second-position type-segment;
Fig. 16, a similari'v'iew of the third-position type-segment; Fig. 17, a group of keys'for vthe-three positions of one character; Figs. 18 and 19, two views of adetail, showing itin different positions; and Fig. 20, a perspective of the general construction, showingthe general arrangement of parts and not confined to the specific form inevery detail. I I 7 It is wellto state-in the outset that in the type-writer illustrated each small letter, ex-
cept a; and 2, has threekeys grouped together,
"as shown; in -Figs..4,,5, and 17,.and as outlined by'the' heavy lines in Figs. 1 and 6, The
lower left-hand key of each grouptmarked 1) in the first-mentioned figures .isthe first-poper on which the letter-press is to be produced isinserted in a; traveling carriage to move across the-face of the type wheel and segments, and the impression is produced by the impact against the reverse side of the paper opposite the type of a hammer, which drives the .paper and an inked ribbon located between the. paper and type against the type when anyone of the said keys is struck. The
sition key, the lower, right-hand key (marked striking of a first-position key operates to ro 4 tate the type-wheel and bring the character which corresponds with that of the key into alignment and to cause the hammer to produce the impression, and the release of the key causes the carriage to travel the distance of one space. When a second-position key is struck, it operates to rotate the second-position type-segment and bring the character thereon which corresponds with that of the key into alignment and operate the ham- 'mer, and when a third-position key is struck ICO it rotates in like manner the third-position segment and operates the hammer. The release of a second-position key causes the earriage to move a distance of two spaces, and the release of a third-position key causes the carriage to move a distance of three spaces. At the middle of the key-board are the-spacing-keys, (shown most clearly in Figs. 5 and 6,) and marked, respectively, 1, 2, 3, and l, to indicate the distance or number of spaces which the carriage will travel when the particular key is struck and released.
To illustratethe operationsay, for example, that the word the is to be writtenthe operator will place the fingers of his right hand on the first-position t-key, the secondposition h-key, the third-position e-key, and the l-space key and press them all down sim ultaneously. This operation will cause the entire word to be printed at once and the carriage to move along four spaces when the keys are released. If the word to be written is these, the operator will strike the letters t h e simultaneously, (but not the 4=- space key, which will cause the carriage to move only three spaces and then strike the first-po sition s-key, second-position e-key, and the 3- space key simultaneously, which will complete the word and space it from the word to follow.
A is the frame of the device. Each key is mounted upon a separate key-lever, the firstposition keys on the straight key-levers t, which are all fulcrumed upon the diagonal rod i, the third-position keys on the angular key-levers s, which are all fulcrumed upon the rod 8', and the second-position keys on the angular key-levers r, all of which are fulerumed on the rod 'r. Fulcrumed at one end at the side of the frame and extending diagonally across the latter nearthe back are levers g, which rest each normally on the ends, respectively, of two levers t, located at opposite sides of the space-key levers, levers g, which in the same manner rest on the ends of two similarly-located levers s, and levers g which rest on the ends of two similarlylocated levers '7'. Thus there are half as many levers q q (l as key-levers t s r, and those of the same class extend side by side, as shown in Figs. 1 and 2.
The type-wheel I3 is provided on its perimeter with the twenty-six small letters of the alphabet,which occupy one-third of the'pcrimeter, twenty-six capitals, which occupy another third, and allthe marks of punctuation and other desired symbols, which occupy the remaining third. The second-position typesegment 0 and third-position type-segment D each have a perimeter equal to about onethird of that of the wheel l3, and upon which are provided only twenty-f0ur small letters of the alphabet, being all but as and The wheel B has a sleeve 13, provided with a pinion W, and is mounted upon a shaft 13, which passes loosely through the sleeve. The shaft is supported at opposite ends in brackets 12' and upon the frame, as shown. The segment 0 has a sleeve 0, which fits loosely over the shaft 1) and is provided with a pinion C and the segment D has a sleeve D, which fits loosely over the sleeve 0' and is provided with a pinion D Upon the outer side of the wheel 13, near its periphery, are six short studs 0, o, 0 0 0", and 0 located equidistant apart. The segments 0 and D have each an arm 0 and D respectively projecting radially t'rom its sleeve at an angle of about sixty degrees from the lower end of the segment. Stops a; w are'formed on the adjacent edges of the arm 0 and segment 0, and upon the segment D and arm D are studs y and y.
Meshing with the pinion B is a segmental rack 91, provided with a head '21., from the up per and lower sides of which extend springarms a and a. A similar segmental rack m meshes with the pinion D and is provided with the head m and lower and upper springarms m and m", and a segmental rack I, like the others, meshes with the pinion (J and has the head l and lower and upper springarms Z i The rack 01. is pivoted at its head upon a short shaft n, mounted in a swinging bracket n, which is fulcrumed at one end upon the shaft 1) and supported at its opposite end by a rod V, hereinafter described. The segmental racks m Z are pivoted at their heads, respectively, upon a shaft Z supported by the arm 12*. Extending between the arms respectively of the racks n m 1, near the free ends of the former, is a rod '5, supported near opposite ends in two substantially similar standards A and A which form part of the frame A. The rod 1' extends through and beyond the standard A, as shown.
Fixed at their ends in the frame and extending transversely across the latter are shafts 7a, 5 and f. The shaft It extends below the series of key-bars t, the shaft 9 below the key-bars s, and the shaft f below the key-bars 7-. Each shaft carries a pair of curved plates h m, g 9 and f f respectively, which extend along the shafts on opposite sides of the space-key bars. upon the shafts and extend normally against the under sides of the respective series of key-bars, excepting only the key-bars of the space-keys; At the end of its free edge nearest the respective end of the shafth the rocking plate 71. is pivotally connected to a rod 72., which at its opposite end is pivotally connected with the free end of the spring-arm n In like manner the plate g is connected by a rod with the spring-arm m and the plate f by a rod f with the spring-arm Z Fnlcrumed at their centers upon the standard A are three levers if, 1 and f The lever 71/ is pivotally connected at one end with the spring-arm n, the lever g with the springarm m and the lever f with the spring-arm l At their opposite ends the levers h, and f" are pivotally connected respectively with the ends of the free edges of the rocking-plates 7L2 g f by the rods 71.5 g f The curved plates rock Belowthe typewhe'el and type-segments is a block, E, having a concave upper faceconcentric with the wheel and segments.

block, one row being adjacent to, the outer side of the type-wheel, the second row coincident with the second-position type-segment,
and the third row adjacent to theouter side of the third-position type-segment.
Extending vertically upward fromthe th,i I-
teen bars q, are an equal number of rods g The thirteen holes of the first-mentioned row in the block E are each in direct vertical line with ,a bar q, and the rods q extend loosely through the holes which correspond with the respective bars from which they rise, andtheir upper extremities normally are approximately flush with the curvednpper surface of.
the block. The holes of the second row in the block Eare in direct vertical linewith the bars (1 and the third row of holes inthesame relative location to the bars g. Rods qtex-Z tend upward from, the bars (1 through the second row of holes, and rods g from the bars q through the third row of holes. Like the rodsq the rods g and g are loose, in the: holes and extend approximately flush with the uppersurface of the block.
The carriage F comprises a frame having. corresponding arms F F and upward-ex-j The carriage is. mounted to moveupon rods G G, supported. by brackets G? G3 on the back of the frame, The carriage is held tothe rods by collars G tending brackets F and E.
which are open, as shown in Fig. 2, to clear the brackets G Eulcrumed at opposite ends respectively in the brackets F F are rollersjH H, normally in frictional contact, and the shaft of the upper roller extends through the bracket F and carries at its end a thumb-wheel H by means of which the upper roller may be turned and by friction rotate the lower roller.
Extending across theback of the frame is a fixed horizontal bar I, having a serrated upper edge, the teeth affording between them thespacing-notches e. Upon the side of the bar I is a barl, provided with notches e,
corresponding with the notches e.. The bar I has elongated slots 6 near its opposite ends and is secured to the bar .I by screws 6 which pass through the slots into threaded holes a in the latter bar. This connection between the bars permits to the bar I independent forward limit of its Fulcrumed at opposite ends in the arms F F and extending parallel with and directly ,over the bar-I, is a rock-shaft 1 formed with a radial plate I. Extending through asocket in the rock-shaft I and pivotally secured therein, is a dog 1 having a weighted arm a, --Whl(3ll.tel1dS.t0 maintain the dog at the lowest limit'of its oscillation.
K isa weight uponrthe end of a cord or like flexible medium K, which runs over a sheave K on theback of the frame and con- I meets at its opposite end with the arm F of the carriage. The dog I engages normally with the notches e and holds the carriage, while the weight K operates to draw'the carriage forward when the dog is oscillated from ter described.
rocking plates h 71 and extending toward each other in rear of the shaft 72, are spacer- .plates, at. The curved plates g and g and f and f? are provided with similar spacer-plates cl in the same relative locations.
L, M, N, and 0 are respectively first, second, third, and fourth position spacer-levers, which are fulcrumed adjacent to each other on therod 8. Each spacer-lever has a head cl'of the width of the notches. e e. and extending normally into the sockets e and a downward-proj ect-in g arm CF. The key-levers ,projecting arms 1?, which extend into contact with the backs of the arms d of respective spacer'levers. On the fourth-position spacerlever O is a lug 613, which projects over the jects over the top of the second-position spacer-lever M, and on thelast-named lever is also-a lug 01 which projects over. the top of ,the first-position spacer-lever L. An arm L extends from the spacer-lever L beyond its the curved plates h 71 andis flangedat the end to rest normally onboth of those plates. In like manner an arm M of the lever M extends to and rests on the plates d, extending from the second-position curved plates f f and an arm N on the lever N extends to and rests upon the plates d, extending from the third-position curved plates g 9 P is a lever fulcrumed on. the rod 1". At one end the lever P is bifurcated to afford a socket P, which fits loosely over the rocking plate 1 and at its opposite end it extends down to the plates d on the first-position curved plates h h ,.whe're it rests normally upon the flanged end of the arm L of the lever L. V
Q is a rock-shaft fulcrumed at opposite ends in the frame and extending transversely across the latter. The rock-shaft Q carries a curved plate Q, which rocks with the shaft and extends normally against the under sides of all the key-levers, except those of the space-keys, the levers of which a re at their the notches e into the notches e, as hereinaf-- Rigid upon the adjacentends of the curved top of the third-position spacer-lever N. On 7 the latter there is a similar lug d which prot of ,the space-keys are provided with upward- TIO fulcrum, down to the two spacer-plates (Z of under edges on a higher plane than the other key-levers, as shown in Fig. 5. At one end the rock-shaft Q carries an eccentric-arm Q R is the hammer, which is in the form of a lever, with a face or striking surface a near one end. The hammer is fulcrumed on a standard A at the back of the frame and extends in a plane parallel with the roller H, directly above the latter. The striking-surface c is in the alignment plane of the type on the wheel B and segments 0 and D, and is maintained normally away from the type by a spring 0' on the standard A. At the end opposite the face c,'beyond its fulcrnm,the hammer is pivotally connected by means of a rod Q with the eccentric-arm Q The inked ribbon S is connected at opposite ends with vertically-disposed rollers S S upon shafts which are j ournaled, respectively, upon the brackets E and l of the carriage. The ribbon is wound upon the rollers, and the latter are provided upon their shafts with thu mb-wheels S The keys are all arranged together in a keyboard, those of corresponding characters being grouped together in clusters. The keys are preferably of hexagonal shape, and so arranged that the key-board may be as small as possible consistent with the necessary size of the keys. The keys of each cluster fitas closely together as practicable. The clusters intermesh with each other, as shown, and to clearly distinguish them they maybe separated from each other by spaces slightly in excess of the spaces between the keys which go to form a cluster, or they may be marked along their edges with lines or the like to render them readily distinguishable. As shown in Fig. 6 of the drawings, each cluster may be marked with its character, the mark spreading over the three keys of the cluster. The aggroup' ment of the keys of corresponding characters into clusters, as described, is a most convenient arrangement, and, besides economizing space, reduces the complexity of the keyboard to a great degree.
The operation of the mechanism thus far described is as follows: When any one of the first-position keys to the left of the space-keys is struck, the long arm of its respective key-lever is depressed and its short arm (in rear of the fulcrum at t) raised. The rise of its short arm lifts the respective bar q, which rests upon it, and raises the rod q, attached to the said bar, through the respective guideopening in the block E to cause the end of the rod g to project into the path of the studs on the side of the typewheel B. As the initial movement is given to the rod q the key lever commences to press down the rocking curved plate 7a, causing it to draw down the springarm a through the medium of the connectingrod h While the spring-arm n is being drawn down the spring arm n, which is of equal resilience with the latter, is stopped from descending with it by the rod 2, as shown in Fig. 18. The arm n is thus caused to yield by the force exerted against the arm n and the segmental rack n is rotated approximately with one-half the speed with which it would be turned were the resistance of the arm a not present, the Work to be performed by the segment offering, as it does, comparatively little resistance to be overcome. It being unnecessary under any circumstances, as hereinafter explained, to turn the type-wheel B (or, in fact, either of the type-segments) more than one-sixth of a revolution, a comparatively slight rotation of the segmental rack against the small pinion B suffices. Thus as the spring n is drawn down the type-wheel is rotated until its stud 0 meets the raised rod q, which prevents further turning of the type-wheel. The relative positions of the openings in the block E and the ends of the rods cf therein, and the stud 0' and small letters of the alphabet on the wheel which correspond with those on the first-position keys to the left of the spacekeys are such that when any one of said keys is struck down and its rod ,1 raised and the type-wheel turned, as described, the engagement of the stud 0' with the rod will bring "into the position of alignment the letter which corresponds with that on the key. As the k-ey'lever is depressed it presses down the curved plate Q, which rocks the shaft Qand turns the eccentricarm Q upward. i Through the medium'of the rod Q the hammer R is thereby turned against the resistance of its spring a and the surface a strikes the paper and inked ribbon against the type, which has by this time been brought into alignment,
and produces the letter-press upon the paper in the manner hitherto common in typewriters. The rocking of the curved plate It described causes its extension or plate (I to turn upward and carry with it the adjacent ends of the levers L and P. This movement of the lever L causes its head d to descend out of the sockets c and that of the lever P causes the latter to oscillate the plate I and swing the dog out of engagement with the respective notch e into the respectively adjacent notch e. The first spacer-head d being out of the socket e and the dog I out of engagement with the movable bar I, the latter is drawn forward byits spring 1 until stopped by engagement of the end of its socket c with the second spacer-head d. \Vhen the key which has been struck is released, the resilience of the spring-arm n draws up the curved plate It and that of the spring 0' the curved plate Q, thereby raising the key-lever to its normal position, causing the barq to descend with its rod g out of the path of the stud 0 and the type-wheel to be turned to its initial position.
the same time swings the dog I out of engagement with the respective notch 6 into the respectively-adjacent notch a, when the weight K will draw the carriage forward and also the bar 1 against the resistance of its spring 1 until the end of its socket c strikes the side of the fourth-position key-lever head The lever P at d, at which time the first head 61' enters the.
carriage has thus been moved ahead the dis tance of one space. When a first-position key tothe right of the space-keysis struck, the short arm of its lever t raises the respective .bar q and causes its rod g to projectabove the block E into the path ofthe studs on the type-wheel. The long arm of the key-lever rocks down the curved plate 71 and draws with it the connecting-rod 71 and lever h, which raises the spring-arm n Raising the springarm ra causes the arm n to bear against the rod 2 and-bend, as shown in Fig. 19, as the segmental rack 42 is rotated downward. This movement of the segmental rackturns the type-wheel in the direction contrary to that before described until the stud 0 strikes the projecting rod g3, at which time the small letter of the alphabet corresponding with that .on the key struck is in the position of alignment. The impression and spacing'are produced, as before described, by the rocking of the curved plate Q and extension at of the curved plate k It will be noticed that the same bar (1 and rod g do duty for aligning one type when the rod g ismet upon one face by the stud 0 and for aligning another type when met upon the opposite face by the stud 0. The striking of asecond-position key to the left of the space-keys causes the short arm .of its key-lever to raise a bar (1 and through it a rod (1 through the block E into the path of the stop 00 on the second-position type-segment 0. At the same time the curved platef',
being turned down, draws with it the connectin g-rod f and spring-arm Z against the resistance of the spring-arm Z which bears against the transverse rod t', and turnsthe pinion. C and type-segment C until thestop wmeets the projecting rod qflwhich brings the type corresponding with that on the key struckinto alignment. The impression is produced by the rocking of the plate Q, as before, and the spacing by the rise of the extension or plate d on the curved plate f, which raises the arm -M of the space-lever M, swings the heads of the latter lever and lever L out of the sockets e and causes the arm L to swing the lever P. When the key is released, the carriage moves forward the distance of two spaces. When a second-position keyto the right of the space-keys is struck, the operation is in all respects the same, except that the curved plate f is rocked, and, through the medium of .the connecting-rod f and lever f raises the spring-arm Z3 against the resistance of the arm 1 and turns the type-segment in' the contrary direction to that described, until its stop a: strikes the, projecting rod which brings theproper type into alignment. A third-position keywhen struck causes its respective barq and rod (1 to be raised, so that the latter will project into the path of the studs y 11 on the type-segment D, and, depending upon whether the key struck is to theleft or rod g to bring the desired type into align;
ment,'or, in the second instance, to turn the segment D in the contrary directionuntil its stud y strikes the rod g for the same purpose. A The impression is produced as before, and the spacing by the rise of the extensionplate 01 of the rocking plate g or g and consequent disengagement from the sockets e of the heads of the three spacer-levers L, M, and N, which permits the carriage to travel the distance of three spaces. When a space-key is struck, the arm t of its lever engages the arm at of the respective spacer-lever and disengages the head of thelatter, and with it (if it be the second, third, or fourth position key) the head or heads of the levers which precede it." Thus, forexample, it the fourth spacekey is depressed, the heads of all the spacerlevers are disengaged from the sockets e and the dog I swung out of engagement with the movable bar I, which latter is drawn by its spring the distance of four spaces, whereby when the key is released the disengagement of the dog from the bar I and its re-engagement with the bar I permits the carriage to be advanced the distance of four spaces.
It is to be understood that in practice, except in thecase of the space-keys, a second-position key is never struck alone, but always simultaneously with a first-position key,and a third-position key simultaneously'with keys of the first and second positions. The typewheel and type-segmen ts are always returned -to their normal positions by their respective spring-arms, which bear against opposite sides of the transverse rod t. The type-wl1eel is provided with characters over the entire surface of the respective third of its perimeter, because some one of its characters is to produce an impression each time the hammer strikes. type-segments O .D, however, which, when the latter are in their normal state's,'are in the position of alignment are depressed or unprovided with characters, so that when a first position character is struck alone no impression is made upon the paper by the type-seg-.
marks of punctuation are of course distributed only over the first-position -keys. I
, T is a key atthe side of the keyboard, mounted upon a leverT', which is fulcrumed Those parts of the perimeters of the IIO at .2 to the side of the frame, and U a key in rear and slightly to one side of the key '1, mounted upon a lever U, also fulcrumed at .2. Resting normally upon the short arms of the levers T U is the rod V, before mentioned, extending through guides l) b on the side, respectively, of the standard A and frame A, and pivotally connected at its opposite end with the swinging bracket 5L to which the head a of the segmental rack n is fulcrumed. Projecting over the short arm of the lever T from the side of the frame is a stop a, and projecting below the lever U from the side of the frame is a stop a. The key T, when depressed until its lever meets the stop a, causes the rod V to be forced longitudinally upward, which swings the bracket 01 upward on its pivot 13. The spring-arm n bearing against the transverse rod t', which acts as a fulcrum, causes the segmental rack a to move upward and rotate the pinion B to turn the type-wheel B one-third of a revolution. This brings the type adjacent to the stud 0 into the position of alignment, so that the figures and punctuation-marks, types, &c., range equally on opposite sides of that position. \Vhen a first-position key to the left of the space-keys is struck, the type-wheel is rotated to cause its stud 0 to meet the respectively-projecting rod g and when a first-position key to the right of the space-keys is struck the type-wheel is, as before described, rotated in the opposite direction until its stud o meets the projecting rod g which in each case brings the proper type into position of alignment. \Vhen the key T is released, the parts are returned to their normal positions by the resilience of a spring V upon the rod V, which, when the rod is raised, is compressed between a collar V on the rod and the guide I). Thekey II, when depressed until its lever U strikes the stop ct, lifts the rod V twice the distance which it is raised when the key T is depressed and causes the type-wheel to be rotated two-thirds of a revolution to bring the type which is adjacent to the stud 0 to the point of alignment. The capital letters are ranged at opposite sides of the type named and are brought, respectively, into alignment by the striking of the stud 0 against the projecting rod g or of the stud 0" against the latter, depending, as before, upon whether a first-position key to the left or right of the space-keys is struck.
