Assuming the invention to be embodied as illustrated, the elements comprehend a basef-rame 31, including a top 32, sidewalls 33, a rear wall 34, a central bottom brace 35, and an intermediate wall 36,- having an integral abutment 37, projecting upwardly relative to top 32, tosupport the type-characters while an impression is made therefrom. The several parts of the base-frame serve to support directlyor indirectly, the various operative mechanisms as correlated for imprinting ordinary and phonetic combinations of characters. i

A shaft 38 is revolubly mounted in frame member 39,. integral with top 32, and has revolubly mounted thereon a concentric shaft 40, including the uppermost type actuator 41, and concentric shaft 42, including the lowermost type actuator 43. A shift frame 44, slides vertically in the base-frame, but does not rotate, and serves as a carrier for the type segments. Type segment is actuated by actuator 41, and segment 46 is actuated by actuator 43.

Type characters

47 and 49 are on the uppermost segment, and

type characters

48 and 50 are on the lowermost segment, and, in normal position, are disposed in equal proportion, on opposite sides of a fixed plane extending through shaft 38 and a vertical printing line opposite abutment37. Each type actuator has a segment 51, provided with correctingnotches 52, each of which is opposed to a type character. Each type segment is connected to and rotates synchronously with its corresponding actuator. Each segment is slidable relative to its corresponding actuator and is adapted to reciprocate through an arcuate path determined by a corresponding guide-way in the lift frame 44'. The type segments are collectively shifted above and below their normal working position to respective operative positions.

The. movement of shift frame 44 downwardly will place type characters 47, and movement upwardly will place type characters 50in the printing zone. The shifting mechanism consists of members 53, mounted on a shaft 54, and having cams 55 and 56.

Members 53, have each an inclined cam slot '57, and shift frame 44 has rollers 30 in endepressed, serve to swing members 53 to elevate the shift frame from its normal position. Levers 61 are pivotally mounted in the forward portion of the base frame, and bear against the base portion62, of members 53. Springs 63, actuate the levers 61, and the arrangement is such that the levers 61 tend to return the swin ing members 53 to their normal position. imilar springs (not shown) serve to return the

key bars

58 and 60 to their normal position whenreleased by the operator. A bar 65 serves as a brace to connect the members 53. Members 53 are arranged with the cam slot open atthe extremity 66. Therefore, when the key-bar has been depressed to elevate the shift frame from its normal position, the rollers 30 will register with the open portions of the cam slots. The shift frame may then be grasped by the operator and lifted from the machine. Each

key bar

58 and 60, is provided with a slot 67, so that, as the key bar is depressed, it will not interfere with the actuating mechanism for the type segments.

For correcting the alignment of the type characters in the printing position, the. stopbars 68 and 69, sliding in brace member 39,

are provided with heads 70, adapted to engage with correcting notches 52. A universal shaft 71 is journalled in the bearings 72, on the side Walls of the base-frame. Lever arms 73 and 74 support a rock-bar 75, allbeing integral with shaft 71 to form a rock-frame. pivot shaft 76 is fixed to central brace mem-v ber 35. Bell-crank levers 77 are pivotally mounted on shaft 76, and have arms 78, extending forwardly, and arms 79 extending upwardly. Stop-bars 68 and 69'are connected to arms 7 8, of levers 77. A bail member 80 extends beneath the key bars 81, each bail member being disposed on one side of a'fixed plane angularly intersecting the printing zone. Stop bars 68 and 69 extend through slots 82in the extremities of the bail members. Slots 82 are so arranged that the bars 68 and 69 are actuated subsequent to initial movement of key-bars 81, and this serves to correct the alignment of the type characters which have been brought to the printing position on the initial movement of the key-bars. In inoperative position, the bars 68 and 69 are normally spaced apart from the upper ends of slots 82.

The mechanism for actuating the type segments to bring type characters to printing position, consists of rock arms 83 and 84, each having a toothed rack 85, a universal shift rail 86 and an integral lever 87 the rock arms and levers 87 being pivotally mounted on shaft 54. Each key bar 81 has an angular and arcuate slot 88, through which a shift rail extends, and is pivotally mounted on key-bar pivot shaft 89. A spring element 90, connected to a key bar to return the key bar to its normal inoperative position. Each cam slot 88, has its angular ortion 92, at a greater or less distance from the shift rail in its normal position, to throw the rock arm through a greater or less are of movement. In a portion of the key-bars the angular portion of the slot is inclined relatively from the shift rail to actuate the corresponding rock arm in one direction from zero position, and in another portion of the key-bars the angular portion of the slot is inclined in the opposite direction to actuate the rock arm in the opposite direction from its zero position. At each end of the rock frame there are providedlevers 61, actuated by springs 63, and bearing against the base portion 93, of lever arms 83, 84, and levers 87. The shift rail is actuated during the initial". movement of a key-bar 81, and passes freely through the arcuate portion of the slots in the remaining and inactive key-bars. The type-actuator 41 is provided with an integral gear wheel 94, and type-actuator'43, with an and an element 91, serves integral gear Wheel 95, in mesh with respecin either direction will actuate the type-seg-' ment-s accordingly. As may be seen in Fig. 16, the uppermost type-segment 45 is providedat each end with a retaining member 96,

Working on the inner side of lift-frame 44,

and the lowermost type-segment 46 is provided at each end with a retaining member A :97, working on the inner side of lift-frame 44.

Lugs 98, projecting inwardly from each retaining member, engage with

corresponding type actuators

41 and 43. A single set of-keybars, therefore, through a corresponding shift-rail and rock arm, will actuate a typeactuator member, andwill oscillate a corresponding type-segment in either direction from its zero position to place any of the typecharacters thereon in the printing position \within the printing zone, during the initial movement of any key-bar.

Hammers 99v and 100, centrally disposed, have platen heads 102, and 103, and are capable of being elevated for printing a half of a type character. The lifting mechanism consists of a pivotal shaft 104, on which the ham mers are hung. The outermost key-bars 105, are pivotally mounted on fixed shaft 54, and their inner arms 106, carry pivotal shaft 104. The depression of a key-bar 105 will-serve to elevate the hammers. Links 107 are connected to arms 79, of bell-crank levers 77. These levers 77, are operated by bail members 80. The hammers are therefore operated synchonously relative to the type aligning-bars, and subsequent to the initial movement of a key-bar. The lowermost platen head 103, is rotatable on a pivot member 108, and is provided with lugs 109 and 110, adapted to engage with a plunger 111, which is actuated by a spring 112, mounted in a recess within hammer 100. "W hen platen head 103 is rotated a quarter of a turn, the pin 113 engages with a corresponding recess in the uppermost hammer 99. The hammer 99 is then actuated by the depression of any key-bar and the movement of either shift rail. When thus locked together, the lowermost platen head 103 is in an inoperative position, being retained in such position by spring 112 and plunger 11.1. In locked position of the hammers, a single line of printing maybe made from

type characters

47, 48 and 49; the

characters

47 and 49 being placed in printing position by actuating shift-frame 44.

With the type segments in their normal I 118. Spacing notches 119, and rack teeth 120,

on bar 118, are provided; An independently revoluble paper shaft 121, loosely mounted in bearings 122, serves to hold a roll of paper 123, of any width to and including a standard sheet. Shaft 121, has knurled ends 124, and is retained by springs 125, in its bearings. Included with the carriage are

co-acting feed rollers

126 and 127. Roller 126, has an integral shaft 128, provided at each end with finger-manipulated buttons 129, and a ratchet V 130, operated by a spring-actuated plunger 131, to engage with a corresponding carriage "end frame member 132. Each finger button 129, has a ratchet 133, which is spring-actuated to engage with an independently revoluble gear pinion 134, mounted on shaft 128.' Roller 126, shaft 128 and finger buttons 129, are integral and rotate as a unit. The rotation of pinion 134 in one direction does not afiect the rotation of the feed roller, as it is held by ratchet 130, in engagement with the carriage end frame member 132. The rotation of the pinion 134 in a contrary direction serves to operate paper feed roller 126 tofeed the paper between the rollers and upwardly into the printing zone. Roller 127 is inde pendently rotatable on a bail member 135,. depending from carriage end frame members 132. Pinions 134 are in mesh with correspondingly geared sector members 136, pivotally mounted relative to frame mem ers 132, and actuated by springs 137. Sector members 136, when actuated in opposition to the tension of retractor springs 137, will rotate pinions 134 in a direction in which the ratchet elements are inoperative to actuate the paper feed roller. When released, the sector members rotate the pinions 134 and op-v erate the feed rollers accordingly. Each gear sector is provided with a slot 138. Finger levers 139, pivotally mounted relative to end frame members 132, and independently operative relative to the corresponding sector members, are provided each with a cam 140, adapted to engage with a corresponding slot 138 in the sector member, and, when moved by the operator, to actuate the sector member.

1 In inoperative position, the sector members and finger levers 139, eachrest in'contact with carriage bar 118. Springs 141 serve to hold roller 127 in contact with roller 126.

Means for detaching a printed portion of the paper web, consist of a bail 142, pivotally connected relative to carriage end frame members 132, and having an integral knife portion 143. Member 144, having a knife ually to inoperative position.

Means for manually line-spacing to advance the paper in the printing zone, consist of a frictionally-held slide 149, mounted on a stud 150, and having cams 151 and 152, which may be positioned in the path'of sector member 136'to limit the movement thereof for single or double spacing.

The carriage escapement mechanism. consists of a slidable reciprocatory member 153, adapted to slide on abutment 154,- integral with bottom brace 35, and to slide on abutment 155 on base-frame wall 36. Lever arms 156, integral with shaft 71, engage with bearings 157', in escapement member 153. Rack gear teeth 120, on carriage bar 118,.are in mesh with escapement gear wheel 158, mounted on stud-shaft 159, integral with frame wall 36 and member 116.

Ratchet wheels

160 and 161, having oppositely disposed teeth, are integral with gear wheel 158. Escapement member 153, has an integral pawl 162, engaging with notches 119, in carriage bar 118. Ratchet frame 163, pivotally mounted on bearing stud-164, has opposed ratchet teeth 165. and 166, to engage with

wheels

160 and 161, respectively. Frame 163 is pivotally con nected to a plunger 167, and has two operative positions. A spring 168, interposed between plunger flange 169 and a swivelly mounted plunger guide 170, serves to maintain frame 163 in either of its operative positions and in engagement with

ratchet wheels

160 and 161. V

The arrangement of the spring-actuated ratchet frame 163, and ratchet

wheels

160 and 161, to actuate gear wheel 168, serves to advance the carriage along its path of movement upon the base frame. As the carriage approaches the limit of its movement, frame 163 will contact with carriage end frame members 132, thereby reversing the operative position of frame 163, andthereby automatically reversing the traveling movement of the carriage. Escapement retractor springs 171 connected to lever arms 156, on universal shaft 71, and to arms 78, of bell-crank levers 1 through levers 7 3 and 74, will actuate univer,v

member 153, disengaging cam 162. On reverse movement of member 153, the ratchets and gear wheel 168 are actuated, thereby advancing the carriage. Upon depression of a single key bar, the rock bar 75, will operate through the slotted extremities 172, of the universal bail which is inactive. As the escapement member approaches the limit of its movement when actuated by levers 156, it engages with a corresponding notch 17.3, in carriage bar. 118, to PIOX BIIt movement of the carriage at the moment of impression.

Means for disengaging the frame 163, from

wheels

160 and 161, during the initial or upward movement of escapement member 153, consists of releasing dogs 174, mounted on pivot studs 175, and extending normally in the path of cams 176, on frame member 163. Stop pins 177, determine the operative position of the dogs to lift frame member 163 to disengaged position. Springs 178 normally maintain the dogs in engagement with the stop pins. 7 On reverse movement of the escapement members the dogs are shifted outwardly by cams 176. The slight depression of any spacing key bar by the operator, will move the escapement member sufliciently to hold the ratchet frame 163, out of engagement with

ratchet wheels

160 and 161. The carriage may then be manually shifted in either direction.

Means for automatically feeding the paper into the printing zone consists of cams 179, pivotally connected relative to brace member 35, and swinging, on each movement ofthe hammers, into the path of cam 180, integral with a gear sector element 136. As the carriage approaches the limit of its traveling movement, a cam 180, on the sector element approaching the hammers, is, actuated, and

this serves to actuate the paper feed rollers.

through a limited arc of movement, thereby advancing the paper correspondingly into the printing zone. This actuation continues until the carriage is traveling in reverse direction, and cam 180 is again out of the actuating zone of a corresponding cam 179. Spring 181 maintains cams 179 in operative position in contact with actuating pins 182, on the printing hammers. The movement of either. hammer will actuate cams 179 and operate to feed the paper.

A ribbon guide 183, having arms 184, sliding in corresponding grooves in the baseframe section 36, has a slotted portion 185, through which a ribbon 186 is threaded. To vibrate the guide upwardly to bring the ribbon into the printing zone, the two-armed vibrator levers 187 are provided, each having a long arm 188 in engagement with an arm 184, of the ribbon guide, and a short arm 189, connected by a link 190, with a lever 19] extending from universal shaft 71. The ribbon vibrator levers 187, are integral with. a

sleeve 192, rotatably mounted on shaft 193, of ribbon shift frame 194. The ribbon shaft frame has an integral pivot shaft 195, journalled in brackets 196, and has integral lever arms 197, each connected by a link 198, with a ribbon shaft key-bar 199. On manual manipulation of a ribbon shift key-bar, the shaft 193, of frame 194, 1s elevate-d, which'corre-- spondingly elevates the ribbon guide,'so that, if a ribbon of more than one color characteristic be used, the different color is brought into the printing zone.

The means for feeding the ribbon consists of spools 200, mounted on rotatable spool carriers 201, which are independently rotatable on shafts 202. Ribbon 186 is adapted to wind from one spool to the other. Lever arms 203, projecting upwardly from universal shaft 71, are feathered to shaft 71 and adapted to slide longitudinally thereon, each arm 203, having levers 204.

Lever'arms 203, projecting upwardly from the actuator shaft 71, have spring pawls 205, in engagement with corresponding ratchet wheels 206, integral with'ribbon spool carriers 201. Feed reversing levers 207 and 208 are connected by a universal link 209, having cams 210 thereon, and are further provided with a short arm 211. A plunger 212 is hingedly connected to the short arm 211, and is supported by a swivel guide member 213. A spring 214 is interposed between the end of arm 211 and swivel guide member 213, and serves to retain link 209 in either of two operative positions, in which a spring pawl 205 is in engagement with a ratchet Wheel 206.

Oscillating levers 215 are mounted in the top of-the frame, and have an arm 216 beneath the top and adapted to engage with a.

cam 210. The outer arm 217 is provided with slits 218, through which the ribbon is threaded. The ribbon is provided near its ends with buttons 219, which actuate levers 215. When the winding of the ribbon on one spool is about completed, a button engages with arm 217 adjacent to the .empty spool, and swings the lever,-thereby through a corresponding cam 210, shifting the link 209. An arm 220 projecting from link 209, ,is provided for manual manipulation of the feed reversing mechanism for the ribbon. Feed reversing levers 207 and 208 are in engagement with levers 204 on lever arms 203, and therefore serve to shift the spring pawls into operative andinoperative positions. Other spring pawls 221,

mounted on levers 207 and 208, serve to prevent a contrary rotation of the ribbon spool carriers, and these are shifted to operative and inoperative positions on movement of the reversing levers. V

To look the type actuator members together, a feather key 222, on shaft 38, is provided. This feather key extends in the inner concentric shaft 40, and may be shifted to engage with the outer concentric shaft 42.

' To lift shaft 38 for this purpose, there is protype actuator members together.

vided a lever 223, pivotally mounted on a shaft 224: connecting brackets 196. The long arm 225, of lever 223, is in engagement with the bottom extremity of shaft 38. The short arm 226, of lever 223, is operated by a bail 227, connected to key-bars 229, the depression of either one of which willserve to lock the Spring 230, returns shaft 38 to its normal position when released bylever 223.

the character key-bars 81, are divided into groups or sets which are disposed on opposite sides of a fixed plane. The set adapted to be actuated by the fingers and thumb of the right hand, consists of four aligned banks of

keys

231, 232, 233 and 23 1. As the typesegments are interchangeable by removing the case-shift frame and substituting another case-shift frame having mounted vthereon segments with different character arrangement, the keys are blank, and may therefore be provided with detachable tablets bearing indicative characters to correspond with the particular arrangement of the seg ments in use.

The first bank of keys 235, includes the variousshift key-bars which may be depressed simultaneously with the charactermoving key-bars. The central key-bars 60, when depressed, serve to elevate the case-shift frame from'its normal position. The special .key-bars. 58, when depressed, serve to lower the case-shift frame from its normal position.

The key-bars 229, next in succession from the central fixed plane, when depressed, serve to lock the type-actuating wheels together. The next successive shift key-bars 199, serve, when depressed, to shift the ribbon guide for printing the type-characters in different color characteristics. The outermost shift-keybars 105, serve, when depressed, to shift the platen hammers upwardly from their normal position. All of the shift key-bars, except the outermost bars 105, serve, when depressed, as

spacer keys to operate the escapement devices for the carriage.

Mechanism associated with the' key-bars mounted in the right side of the base-frame, serves to actuate a type-actuating wheel to rotate in either direction. Mechanism associated with the key-bars mounted in the left side of the base-frame, serves, to actuate, on depression of a'left character key-bar, a corresponding type-actuating wheel to rotate in either direction. The left-hand key-bars therefore actuate the lowermost type-actuating wheel, and the right-hand keyrbars therefore actuate the uppermost type-actuating wheel. Means for locking

levers

58,60, 105, 199,,and 229, in depressed position, consist of pivotally mounted cam-levers 236, which may be moved into the path of said levers when in their depressed position.

Type-

segments

47 and 49 are connected to operate synchronously, and type-

segments

48 and 50 are similarly connected. They there fore will move in pairs in annular ways on frame 44. Each pair of integral segments is mechanically connected with and operated by the keys of a corresponding key-set. In their'normal and independent relation, each pair of type-segments can be actuated only by'the keys of its corresponding set. When,

F I however, the two pairs are locked together Referring to F 1g. 24, 1t maybe seen that as hereinbefore described, then, all segments being operable as a single segment, they can be actuated by the keys of either set.

Forty type-characters are arranged in lateral alignment on each segment, there being twenty to the right and. twenty to the left of the vertical printing plane. The type characters which 'may be moved to the printing plane by the right hand set of keys are alternately arranged relative to the type characters which may be moved to the printing plane by the left hand set of keys. Assuming the type-characters which are to be operated to printing position by the right-set of keys to be represented by the character (0) and the charactersto be operated by the left set of keys to be represented by the character the type segments would be represented by the following arrangement of characters:

The type-characters, when at rest, will be hand keys will move only the charactersto printing position, each set of keys operating only a pair oftype segments. When the lll segments are locked it is obvious that any key of the right key-set moves'a corresponding column of (0) characters to printing position, and any key of the le key-set moves a corresponding column of U) characters to printing position.

Toillustrat-e the disposition of type characters on the segments relative to the key arrangement, the following may be assumed as one of any number of possible arrangements:

With the above arrangement ofkeys, the type character arrangement onthe segments .cetfkkppttijvvbbddss The purpose of the four segments is to provide more ample means for symbolic representation and for abbreviation in stenotyping the characters that, are on the diiferent segments. For a special use or system, the characters on thesegments may be wholly different. However, this method is preferred for stenotype purposes.

To illustrate the full arrangement on the four segments, the principle of a differentiating characteristic may be designated in a diagrammatic arrangement by the use of capi- 6 ml letters on one segment, and by underscoring on others. It will also be an-advantage in stenotypin g to distinguish those characters which can only be printed by locking the segments together. The differentiating characteristics on the segments for stenotyping may be indicated by the following:

OCFFKKPPTTJJVVBBDDSSNNR will give, for example, i, which may be understood to express kr kthe underscored letter signifying that the phonic r is to be put between the printed characters. In like manner would symbolize -trs. Thus, by two siTnult-aneous depressions the symbols would be 2% and thereby indicate the phonetic outline krktrs which is sufiicient in short writing practice to stenographically symbolize the term characters.

The printing of a single type symbol may nnrr'llmmaaeeiioou'u RLLMMAAEEIIOOUU ccff'kkppttjjvvbbddssnnrrllmmaaeeiioouu The operation of the duplicate mechanism for stenotyping consists in the use of a duplicate set of characters as above set forth. By means of this arrangement syllabic symbols may be composed for the more important of the phonetic combinations by a single simultaneous depression of two keys, one from each set. Phonetic characters of a syllable are typed one above the other in a lateral series as described, and thus represent graphically unitary and individualized syllable symbols. The duplicate arrangement of characters relative to the keys involves the principle of having similar character keys for operation by corresponding digits of the two hands.

To illustrate further the use of the four segments and their type charactistics, take for example a method of writing the word characters. This word may be sufiiciently symkats. there rkr being four depression periods, in three of which thereis a simultaneous depression of two keys, one of each set. The operation for double typing in this manner is more rapid than the typing of the ten characters in the ordinary manner, assuming skillful operation. However, the symbolic representation and the typing may be further simplified. It is a feature of the invention that the typesets oneach segment difier initype form. For example, on the first set, there may be small bolized phonetically thus:

TIJJVVBBDDSSNNRELLMMAAEEEllQOEE be mnemonically used to represent a word phrase according to its peculiar'type form, its position in the upper or lower line, its color characteristics, or by printing said symbol in portion, as well as other distinctions achievable by a combined use of these devices as provided for.

Since the left key-set prints in operation normally the upper line of characters with out shift of the case-shift frame, it will be evident that this is reversed when shifting to the upper or lower case position, and that the superposed characters are printed by keys of the opposite or right key-set. Certain honetic elements and combinations as those alphabetically symbolized by y, 11, q, w, x, and z, which may not be provided with a corresponding key and type character, may be designated by writing a symbol to which they adjust the lower hammer head out of its normal position. By using the three upper segments for the type characters for typing, and employing the upper and lower case shifts,

on the second; capitals, and onthe third,

as many as one hundred and twenty type characters may be made available for printmg.

Employing a key board of approximately the so-called standard arrangement, as

levers

60, 58, 229, 199 and 105 in depressed position, consist of pivotally mounted cam levers 236 which may be moved into the path of said key-bars when the key-bars are depressed. If the type-segments be locked together as herein described, and the lowermost printing platen be turned to inoperative position, the characters will then be printed in a single line. Forty characters may be printed with the case-shift frame in normal position.

- On elevating the case-shift frame, an additional forty characters may be printed on de pressing the key-bars, and on depressing the case-shift fr me from normal position, another additional forty characters may be printed.

From the description, it may be seen that the typewriter is further adapted for printing type-characters in two parallel rows and with the simultaneous depression of a key of one set and a key of another set, that two characters are printed in vertical alignment. An individualized syllabic character is thus formed by the printing of the two type characters, and a number of such characters may be written to form a single line of such syllabic characters or word-signs. For the phonetic writing, the type-segments have the characters arranged in practically duplicate sets on opposite sides of a fixed plane. Any system of phonetic or stenographic characters may be employed merely by substituting a case-shift frame having thereon the type-segments which are desired. This method of typing and using phonetic and other general characters insures great advantages in speed and accuracy of recording speech in condensed form.
