Specification of Letters Patent.
. Patented Bed. 31, 1912.
Application filed September 10, 1906. 8erial No. 334,029.
To all whom it may concern:
Be it known that I, \VILLIAM H. CLAY- TON, a citizen of the United States, residin at Poplar Bluff, Butler have invented anew and useful Type-Writing Machine, of which the following is a specification.
This invention relates to improvements in the construction, combination and arrangement of parts included in typewriting machines generally, and in the present embodi- "ment of the invention it relates more spea letter spacing under control of a novel train to produce a compact, strong of mechanism whereby each key controls and V operates its proper type-bar; an improvement in the construction of the type-bars, each of which carries three distinct characters disposed thereon in a row, and the middle one of which strikes the platen except when the parts are specially adjusted to permit others to strike and make impressions; an improved mechanism for supporting the type-bars and mechanism controlling the supporting mechanism operable to move the same as requiredto cause any desired character to strike the platen when the typebars operate; improved tabulating mechanism for adjusting the platen for column printing; improved devices for rendering uniform the touch of the variouskeys which, necessarily from the construction of the parts, operate type-bars of different sizes and weights; and various other improved combinations and features of'arrangement and construction, all of which are particularly set forth herein.
One object ofv the invention, therefore, is and durable typewriter containing the combinations above and hereafter set forth, all designed to operate in harmony substantially as herein specified, and thereby produce records all of which will be visible to the operator count-y, Missouri,
without manually moving any of the parts after therecords have been made.
It is a further object to arrange and combine the entire tvpewriting mechanism so as to provide a relatively large open space between the key levers and within the machine below the platen, and toward the rear end of the machine in order that other mechanism may be mounted therein, a portion of which, in order to illustrate the location thereof, is shown in the drawings. I Another object is to produce a typewriter comprising two separate groups of typebars one of which is supported in a pivotally mounted .frame at each side of machine thereby leaving a central space of considerable width wherein other mechanism adapted for combination with this machine can operate without obstruction. from the typewriter parts, and mechanism for moving said pivotally mounted frames as required to produce impressions from the several types on each type-bar. moved only for lateral spacing and line spacing.
'Another object is to produce in combination with the platen and the automatic letter spacing mechanism coiiperating therewith, improved tabulating mechanism whereby the platen may be caused automatically to 'move laterally the width of one or more column spaces, and including a device for restraining the platen so that it will not move or stop with too great speed or force, which would eventually damage some of the parts. Mechanism is also provided operable to release the controlling mechanism from the platen so that the platen may be moved manually any required distance in either direction. 7
Other objects and advantages of mainvention will appear from the following description, reference being made to the accompanying drawings in which- Figure 1 is a side elevation of a typewriter constructed in accordance with the principles of my invention, and also illustrates an independent bank of keys and key levers and a portion of the mechanism controlled thereby, said key levers and the mechanism controlled thereby being mounted within the machine and below the platen, out of the Way of the typewriting mechanism so as not to interfere with the operation thereof.

Fig. 32'is a plan view of the typewriter key board and shows the position relative thereto ofan independent set of keys. Fig. 33 is a'sectional view showing ported by the carriage end plates. I
The base 1 sustains rigidly the two side frames 2. The base extends forward a considerable distance beyond the side frames and the keys 3 are disposed in a conventional or preferred arrangement over the front part of the base. The keys 3 are the type writer printing keys, and, through the medium of a. train of mechanism leading therefrom, their operation results in operation of Two posts or frame pieces 4 are secured to the base between the front. ends of the frames 2.
plate 5 (Figs. 28 30 and 32) is attached to the frame 2 at the left side of the machine relative to the operator, and to the right frame and to each of the posts or frame 4 pieces 4 a plate 6 is fastened (Figs. 31 and Between the plates 5 and 6 at one side like block'is secured between the plates 5 and 6 at of the machine (Fig, 32). These blocks,
number of slots 8 on their front sides and in each slot a key lever 9 is pivoted, each lever comprising a horizontal arm terminating in its key 3, and a vertical arm. The keys are arranged in transverse rows as usual in machines of this character, which requires that the horizontal arms of some of the key levers be longer than others. .To compensate for this unequal length, so that the touch of all the keys will be uniform and so that equalmovement of all the keys for writing purposes as required and maintained, the pivots are arranged nearer to or farther from the connecting devices, depending upon the length of the levers. For instance, the keys in the front row have longer levers than those in the remaining rows and the other side -which are duplicates, are provided with a same distance to produce uniform records.
as indicated at 12.
To produce this result the longer or front row key levers are pivoted near theirangle as indicated at 10 v next row at, 11, and the lovers in the rear row are pivoted farthest from their angles In this manner the key levers are pivoted int-W0 groups, leaving between said groups a relatively large open space which may be to Fig. 32.
At the rear of the machine two shafts 13, 14 are supported by the side frames 2. A pairof arms 15 near each side of the machine are removably secured to said shafts by clamp devices 16. The forward ends of each pair of arms are connected by one or more rods 17 thereby forming a strong frame, and another rod 18 is supported in each frame behind said rods 17. A number of substantially vertical levers 19 are supported by said rods 18 spaced apart by washers or hubs 19 and near the upper and lower ends of said levers in the rear sides thereof are formed notches 20. The levers' 19 correspond in number to the key levers 9, to which they are connected by means of links. The connecting links are all alike, and one of them is shown. in detail in Fig. 10. Said link comprises a central portion 21 to the front and rear ends of which are attached slotted plates or loops 22, adapted to receive the lower ends of the levers 19 and the upper ends of the vertical arms of the key levers 9; and to rest within the notches 20 in said levers 19 and within corresponding notches 23 in the key levers. As shown in Fig. 2 thelinks are properly connected to the key levers at different distances from the ends thereof, as a further compensation for the unequal length of the levers in order to secure uniform touch and movement. The upper ends of the levers 19 areac'tuated forward by springs 24 connect- .ing the levers with the rods 17. It is ob vious that depression of any key lever extends the corresponding spring 24 and that the key levers will be restored to idle posi-' tion by said springs after operation. The key levers are gulded and restrained against lateral oscillation by a series of teeth or projections 25 extending between said levers from a comb plate 26 which is supported under the horizontal arms of the levers.
Su ports for the type-bar frames are remova ly secured to the upper sides of the side frames .2 near the front edges thereof. These supports are symmetrical and consist of the vertical portions 27 and the inwardly projecting horizontal portions 28. Angular frame parts 29 are hinged to the upper ends of the supports, said frame parts conforming in general shape with the supports to which they. are hinged, and are sustained in (Figs. 23 and 31), the
understood by referringsuch position that their horizontal arms may be raised and lowered 'as hereinafter described. A plate 30 is rigid or integral with each of the frame pieces 29 and said plates are secured to the frames 31 wherein the type-bars are pivoted. The last named frames consist of upper and lower parts the inner ends of which parts in each frame are fastened together and the said parts extending downward and outward therefrom (see Fig. 7). The rear end of a rest piece 32 is fastened to the inner end of each frame 31, said rest pieces projecting forwardly and obliquely downward and outward, and being strengthened by braces 33 connecting their outer ends with the lower corners of the frames 31. The type-bar frames 31 are detachable from the supporting parts 29, so that an entire typebar frame including all the type-bars thereon may be conveniently taken off the machine for repairing or other desired pur oses.
' The spin les 34 of the type-bars 35 have bearings in the upper and lowr parts of the frame 31. The upper ends of the spindles are threaded (Fig. 12) and receive the interlocking nut 36 after removal of which the type-bars may be taken out. The several type-bars 35 are rigid on their respective spindles and are preferably formed with hubs 36 whereby they will be more securely held. The type-bars 35 project forward in substantially horizontal position graduating serially downward and outward on the under sides of. the frames 31, as re quired by the shape of said frames. The type-bars are of the same general shape and are of graduated lengths, and their spindles are arranged at proper inclinations so that when operated they will strike at the same point'on the platen. The forward ends of the type-bars bend upward as indicated at 37, one in front of the other so that any one may move without contact with any others. On the parts 37 of the type-bars the type heads 38 are secured facing inward, each type head having a groove in its outer side whereby it is fastened onto the type bar and having three characters 39 engraved in a row on its inner face (Figs. 3 and 7 The middle character will strike the platen upon operation of the typewriter keys except when the type are moved by the shifting mechanism to cause the upper or .lower characters to print. The rear. ends of the several type-bars have lateral projections 40 to which are connected the front ends of links 41 leading from levers 19 and connected therewith by slotted plates or loops 412' resting in the notches 20. In this way the several keys are connected with their respective type-bars, all of the connections being illustrated diagrammatically in Fig. 10. Inasmuch as the levers 19 are restored immediately to idle position after the operated -keys are released, and as the idle position tached to the ends of the shaft 50, to be en-' to a rock shaft 60, by
' from the printing point,
-line spacing or other purposes,
ford means torestrain or to move ,the platen automatically swmg back to their idle position after release of the keys. j Two standards 43 are secured on the base of the machine and the upper ends of said standards support a track member 44 which has longitudinal grooves 45 in its upper and dower edges. A channel movable member 46 incloses the track member 44 and is provided with longitudinal grooves 47 matching the grooves 45, and within the passa es formed by said grooves a number of ba ls 48- are located to facilitate lateral movement of the platen, and carriage, which are supported by the said member 46. A plate 49 is attached to each end of the art 46 and in said plates the platen shaft 50 is journaled, said shaft carrying the platen 51 which may be of any known or referred construction. Knobs 52 are atgaged for manual rotation of the platen for and also af- The rear side of the part 46 carlaterally.
' with which meshes a pinion ries a rack 53 54 attached to the forward end of a shaft 55. The rear end of the shaft 55 is in an adjustable bearing formed'witha supporting part 56 and two screws 57 operating in lateral holes, acting as pivots for the shaft and capable of adjustment to tighten or loosen the shaft therein. The front end of the shaft 55 is mounted in a bearing 58 sup-' 59 which are attached rocking which the pinion 54 may be lowered out of mesh with the rack 53 and thereby permit unrestrained lateral movementof the platen. The pinion is upheld in mesh with the rack by a spring ported by two arms 61 connecting the upper end of a lever 62 shaft 60 with a stationary part of the frame. On the rear end of the shaft 55 an escapement wheel 63 is attached, said wheel having a number of teeth or projections 64, shaped substantially as illustrated in Figs. 13, 15 and 17. A rock shaft 65 is supported by the frames of the machine below the wheel 63 and has an arm 66 rigid therewith adjacentto the said wheel. An escapementpart 67 having a notch 68 in its upper end is separably attached to said arm 66. p The peculiar shape of the teeth 64 on the wheel and of the notch permits the wheel and shaft 55 to rorigid on the rock tate step by step one toothat a time when construction and connection is utilized, said motor being supported on a bracket 70 secured to the track said type-bars will:
arm 85 attached to the rock s 7 44. Behind each group of levers 19 a rod 71 is supported by arms 72 attached to" the rock shaft'65. From the arrangements of these parts it is obvious that when any of the ty ewriter keys is depressed the shaft 65 will be rocked and the escapement device operated, so that the platen may be moved one space leftward. The arrangement of the parts comprising the escapement relative to the levers 19 and -intermediateparts is such that the platen will be moved only after the type has struck and rebounded so thatthe printing will be clear and distinct and not blurred or marred as would be the case were the platen 00 move with the type held against the rib- To operate the escapement and permit the platen to move for word spacing and the like, special mechanism is rovided. In front of the keys 3 a space ar 73 is carried on two stems 74 which operate within guides 75 and project below the base (Fig. 1) where they are pivoted to levers 76 attached to a shaft 77. A link 78 is connected to an arm 79 on the shaft 77 and leads to a second link 80 to which it is connected by pin-and-slot connection 81 so that depression of the spacing bar will cause both links to be moved backward, but permitting the link 80 to be moved independently of the spacing bar. The link 80 connects to an arm 82 on a rock shaft 83 at the rear end of the machine. A link 84 connects an aft 83 with an arm 86 rigid on the rock shaft 65, whereby the escapement is operated. From the foregoing it is obvious that operation of the spacing key will cause the escapement controlling the platen to operate and thereby permit the platen to be moved step by step laterally. The plates 49 which carry the platen support a bar 87 which has a series of holes 88 adapted to receive the stop pins 89 which are removable. Bearings 90 are rigid with the track 44 and a rod or shaft 91 is mounted therein. An arm 92 is mounted on the shaft 91 and is actuated forward against the bar 88 by a spring 93 encircling the shaft. Said arm has a projection extending under the bar 87 against which one of the pins 89 will strike and thereby the latter has moved the required distance. These pins may be adjusted to limit right and left movement of the platen and, by proper adjustment, will stop the platen at any desired positions.
Near one end of the shaft 65 (Figs. 5, 15 and 16) is a lever 7 1 pivotally supported by the frame of the machine, and adjustably sustained by a screw 71 in a bracket 71. A spring'72 connects said lever with an 'arm 72 attached to the shaft 65, which controls. the escapement. The arm 72 is stop the platen when.
between two screws 72 adjustable in the tension exerted by the spring 72' can be increased or reduced by means of the screw.
71 Said spring operates the escapement members supported by the shaft 65 back to idle position after their operation by the eys.
Near one side of the machine a tabulating key is located, which key is operable to release the escapement from the platen carriage and thereby permit the platen to shift at a single movement any desired distance leftward. Said key comprises a rod 94 (Figs. 2 and 4) supported at its front end in a bearing 95 attached to the frame 2, and connected at its rear end to the lower end. of the lever 62 attached to the rock shaft 60. A spring 96 encircles said rod between its head and the bearing 95 and assists in actuating the rod forward and, through the lever 62, in holding the pinion 54 in mesh with the rack 53. A slidable collar 97 is on the end of the rod 94 and bears against the lever 62. A spring 98 encircles the rod 94 in front of the collar 97 and behind another collar, and thereby makes the connection between the rod 94 and the lever 62 yielding but of suflicient tension that when the rod is pushed rear-, ward it will oscillate the lever and thereby ro'ckthe shaft 60 and so disconnect the pinion 54 from the rack 53. Thereupon the platen will be drawn leftward and to prevent too rapid movement and sudden stops a brake device is employed to restrain the platen so thatit will move quietly and easily until stopped by the pin 89 striking the arm 92. This brake device consists of a lever 98 pivoted to one of the arms 59 and provided with friction part or brake shoe 99 on its upper end adjacent to the bar 87 in the platen frame. An arm 100,0n said lever extends over the shaft 60 so that when the arms 59 are lowered said arm 100 will engage against the said shaft 60 and thereby fo-rce the part 99 against the bar 87. The frictional contact of the part 99 and the bar 87 will cause the platen to move slowly to position and prevent any sudden jerks or stops. A screw 101 operates through the arm 100 against the shaft 60 and affords means for adjusting the brake to conform to different degrees of pressure as required.-
Below the bar 87 a cam bar or shaft 102 is mounted in bearings in the platen end plates 49. The rear side of this bar 102 is a plane (Fig. 20). A lever 103 is mounted on? the shaft 91 and has its upper end close against the bar 102 and its lower end extends over one of the arms 59 by which the bearing for the shaft 55 is supported. Rotation of the bar 102 operates the lever 103 and pushes down the arms '59 and thereby disconnects the pinion 54 from the rack 53 and permits the platen to move freely in either direction. A lever 104 is secured to each end of the bar 102 and affords means for manual engagement to turn the bar 102 and thereby operate the lever 103. Such operation permits the platen to be moved manually in either direction and to any desired position in which it may be stopp'ed by releasing the lever 104, whereu on the spring 93 will restore the lever to i e position and permit the escapement again to couple up.
Near the side of the machine the ribbon spools 105 are mounted on vertical shafts 106, the upper ends of which are journaled in bearings in the horizontal parts 28 of the supports for thetype-bar frames, and the lower ends project through, and have bearings in, the base 1 (Fig. 1). Slots 107 for said shafts 106 are formed in the horizontal parts of the parts 29 so that the latter may be moved vertically without interference with the shafts. The ribbon 108 winds on the spools and extends across the machine in front of the platen just below theprinting line. The lower end of each shaft 106 has a worm wheel 109 attached thereon whereby 'said shafts will be rotated and the ribbon wound from one spool to the other as desired. A worm 110, of known construction and arrangement, is supported in position to operate the shafts 106. At the middle of the shaft 110 is a toothed wheel 111. The link 80 has a forward projection 112 having teeth engaging with the wheel 111 so that each backward movement of the link will rotate the shaft 110 slightly and thereby the ribbon spool shafts 106 causing the ribbon to wind from one spool to the other. The link 80 is quided bv a member 113 attached to the base and having-a slot 114 wherein the link moves (Figs. 1 and 25). It is obvious from the foregoing that operation of the spacing bar 73 in addition tocausing the platen to travel laterally, will also wind the ribbon from one spool to the other, and it is obvious also that operation of any of the typewriting keys will produce the same result bv rocking the shaft 65 and moving the connections leading therefrom to the link 80.
Two arms 115 are suspended from the shaft 91, and said arms are of substantially arcuate shape and extend forward under the platen (Figs. 1 and 13). On the forward ends ofthese arms a ribbon-guide frame 116 (Figs. 2 and 26) is attached, said frame be ing in front of the lower part of the platen below the printing line. An upright part 117 having a forwardly extending hook 118 is at each end of the frame, there being a passage or slot 119 separating said upright parts from the frames. The ribbon passes across in front of the platen (Fig. 2) in slot 131 in the plate 5, and a pin 132 at its horizontal. A spring 134 .plished when the typewriter keys are operated. The arms are connected and braced by a rod (Fig. 13) from which a link 121 leads to a lever 122 which is pivotally supported at its. lower end at 123.
The upper end of said lever 122 is connected to an'arm 124 rigid on the rock-shaft 65, by a link 125 so that, when said shaft" is rocked by the typewriter key connections, the arms 115 through the medium of the connections just described leading to said shaft, will be raised the required distance to position the ribbon over the printing line to receive the impact of the type. The parts arearranged so that the ribbon will be so positioned before the type strikes, and will be held until the key is released, and the train of connections between the key and its type-bar have started back to idle position.
As stated heretofore in describing the type-bars and their frames and supports, it is necessary to move the type to cause the upper and lower characters to print. The
plate 5 and the adjacent bearing block 7 (Figs. 28 and 32) support a plvot pin 126 on which is mounted an angular key lever 127, one arm of which extends horizontally forward and is provided with a key 128 arranged at the end of one of the rows of keys 7 ward from the pivot. A lever 129, comprising a vertical part and'a horizontal part extending rearwardly from the vertical part midway of the ends thereof, and having a in at its upper end projecting into a lower end projecting into a slot 133 in said plate, is pivoted to the lower arm of the,
angular key lever 127 by means of the pin 132 at the lower end ofsaid lever 129. The idle position of the lever 129 is that in which the pins 130 and 132 thereon are in the front ends of their respective slots in the plate 5, and in which the rear arm of said lever is is connected to the vertical part of said lever 129 midway of its endsa'nd to a forwardlyprojecting arm 135 on the plate 5, and serves to hold saidlever in idle position and to restore it to such position after operation, all of which will be understood by reference to Figs. 28 and 29. Depression of the lever 127 will raise the rear end of the lever 129, the pin 130 on said 3 and the other arm of which extends downpin reaches the end of the slot 133. A link 136 (Fig. 1) connects the rear end of the lever with one of two arms 137 attached to opposite ends of a transverse shaft 138 supported'just above the base of the machine. 0 each of said arms 137 a vertical link 139 is connected, and the upper ends of said links connect to arms 140 attached to rods or shafts 141 journaled in bearings 142. On the opposite ends of each of said shafts 141 an arm 143 is attached, and said arms are connected to the adjacent pivoted type-bar supports 29 by links 144. From the foregoing it is obvious that depression of the key lever 127 will raise the two groups of typebars, such movement being limited by the pin 132 in the slot 133. This movement is just sufiicient to position the type-bars so I that when the typewriter keys are operated the characters 39 which are lowest on the type heads will strike the printing point and record. Upon release of the lever 127 the parts are restored to idle position by the spring 134.
To lower the type as required to print the uppermost characters on the type heads a special key lever 145 is pivoted to the plate 5, and provided with a key 146 also at the end of one of the rows of keys 3. Said le-' ver is pivoted at 147 and has a downwardly projecting arm the pin 130 on the lever 129. A slot 149-in said lever 145 receives the pivot pin 126 and permits operation of said lever 145. Depression of the lever 145 oscillates the lever 129 on the pin 132 as a pivot and lowers the rear end of said lever which, through the connections described in connection with the lever 127, lowers the typebar supports 29, to position the uppermost characters on the type heads for printing. The parts are stopped at the. required position by the pin 130 reaching the end, of the slot 131. Upon release of the lever 145 the parts are restored to idle position by the spring 134 as in the case of the lever 127.
'The manually operable mechanism for moving the platen, and other mechanism cooperatlng with the platen for adjusting the same, are supported by the plates 49. At the right of the machine relative to the op- I erator, is an angular lever 150 having the end of one of its arms pivoted to the bar 102 and the other arm projecting vertically and provided with a hand-hold 151. An arcuate slot 152 in said lever receives the platen shaft 50 (Fig. 13), and permits oscillation of the lever without obstruction from the shaft. Said lever is "sustained by a spring 153. A pin 154 on the lever 150- projects behind the lever 104 so that when the lever 150 is lowered the lever 104 will be operated, which result-sin release of the escapement from the platen by means of the lever 103 controlled by the bar 102 to which 148 which is connected to said lever 104 is attached. It is obvious, therefore, that by operating the lever 150 the platen may be guided manually in either direction and to any desired position. At each end of the platen shaft a ratchet wheel 155 is attached, the teeth on the said wheels being arranged suitable for line single spacing. The lever 150 carries a T-shaped pawl 156 the lower end of which is actuated forwardly toward the ratchet wheel 155' by a spring 157., The adjacent plate 49 supports a member 158 which has an arm 159 projecting over the top of the pawl 156. A sleeve 160 is slidably mounted on the arm 159 and in the under side of said sleeve a notch 161 is formed. (Fig. 14..) In idle position the end of the front arm on the pawl 156 engages against the sleeve within the notch and in such position the lower end of the pawl is held away from the ratchet wheel 155 so that the platen may be rotated freely in either direction. When the lever 151 is engaged and lowered the pawl 156 engages the wheel 155 and rotates the platen forward two teeth or spaces, and thereby adjusts the paper for double space printing. The lever 151 is intended to be engaged after each line of printing to move the platen laterally for the next line, and the rotation of the platen for line spacing is automatically accomplished. If the sleeve 160 be moved endwise the pawl 156 will be held farther back and will engage one tooth lower on the ratchet wheel 155 and, upon operation of the lever 151 will rotate the thereby adjust the paper for single space printing.
162 indicatesa feed roller operating, in connection with the platen, to assist in insorting and moving the paper in line spacing. This roller is supported by two levers 163, pivoted to the frames49, and actuated bysprings 164 to hold the roller against the platen. Oscillation of the levers 163 in opposition to their springs 164 will move the roller 162 away from the platen and leave the paper free for manual adjustment. For this purpose levers 165 are attached to a shaft 166 supported by the plates 49 and bear against inclined surfaces of the levers 163, so that operation of said levers 165 will move both of said levers 163 and thereby the roller 162. In addition to the pawls 156 whereby the platen is rotated as before described, a pawl 167 is sometimes arranged to operate upon each of the ratchet wheels 1555 and whenever it is desired to rotate the platen to move the paper backward said pawls must be disengaged from the ratchet wheels. Each of said pawls has a pin 168 projecting through a slot 169 in the adjacent plate 49, said pins also projecting over the ends of the levers 165 whereby back- 'wa-rd movement of the lovers will raise the platen one tooth or space, and
ward into the lower portion of the large central space around which the typewriter mechanism is built as described, and wherein a portion of the adding machine mechanism 171 is shown. The typewriter keys are operable independently of the keys 170 to perform all the usual functions of the typewriter and the special functions herein described. Further illustration of the adding machine mechanism is believed to be unnecessary in this application.
