TYPEWRITING MACHINE Filed Dec. 7, 1931 5 Sheets-Sheet 5 June 26, 1934.

Patented June 26, 1934 UNITED STATES PATENT OFFICE 56 Claims.

This invention relates to typewrting machines, and more particularly, to means for facilitating the making of multiple copies.

As in my prior application, Serial No. 410,477,

filed November 29, 1929, on which this invention is an improvement, the transfer medium of the present invention is in the form of a disk entering between the superposed strips or sheets carried by the platen of the typewriter and adapted to roll through the superposed strips as the typewriter carriage is moved in letter-feeding direction.

A feature of the present invention is the provision of means mounted at one side of the typewriter for holding the transfer disks in operative position at the printing point, thus leaving one side of the machine free from any encumbrances.

In the form of the invention illustrated. which is that at 'present preferred, the means for holding the carbon disks comprises a plurality of arms pivotally mounted on the'supporting means and movable into operative position from an out-lof-the-way position up away from the platen, the mounting of the arms and their supporting means being an important feature of this invention.

In my prior application, the mounting for the transfer disks was so arranged that the circumi'erential margin of the disk could be moved vertically with relation to the line of writing, so that the operator by manual adjustment could utlizethe greater portion of the annular margin of the transfer disk. However, it was found that with this arrangement, the fact that the carbon was becoming worn would not be noticed by the operator until Vafter the impressions had become very weak.

According to the present invention, and this is an extremely important and advantageous fea- 40 ture thereof, the transfer strip is movedvermany with relation to the line or writing Vas. well as being rotated during the travel of the typewriter carriage. thereby distributing the impressions taken from the transfer disk over a substantially wide annular margin of the disk.

Again, with my prior device, since it rotated during both the leather-feeding and return movements of the typewriter carriage, the relation of each part of the annular margin of the disk to a part of the line of writing was substantially constant. Hence. those portions of the transfer diskrelated to the portion of the line of writing receiving the greatest number of im- 65 pressions would become worn and exhausted of (Cl. IS7-128) transfer material before other portions of the annular margin of the disk.

This is obviated by the-present invention by holding the disk raising and lowering device against rotation during the return movement 6 of the carriage and causing the first impression of the next line of writing to be in'an entirely different place from the first impression of the previous line of writing.

A further feature of this invention is the proe5 vision of means for pressing the superposed strips and transfer disks together above the line of writing to thereby avoid the presence of air pockets between the strips and disks at the line of writing and thereby cause the impressions to be sharp and clear.

A still further feature of this invention is the provision of improved means for attaching and mounting the carbon arm supporting means on a typewriter frame, the clamping means being so arranged as to flt the frame of any typewriter on the market.

Other features and advantages will hereinafter appear.

The typewriting machine shown in the accompanying drawings is of a conventional type having a cylindrical platen 20 rotatably mounted in a carriage 21 which itself is mounted for 1ongitudinal movements in a frame 22 under the control of letterJeed mechanism not shown. In front of the platen there is a ribbon 23 against which type bars 24 are adapted to strike and cause impressions to be made on the uppermost of the Worksheets or strips 25 when the keys 26 are operated; the keys 26 in their operation also causing the platen 20 and carriage 21 to move step-by-step toward the left. After a line has been written, the carriage 21 may be returned by means of a lever 27, operation of which, through line-spacing' mechanism 28, causes the platen to be rotated to bring a fresh portion (i. e. the next line) of the worksheets or strips to the line of writing. The work 25, which may be in either sheet or strip form, is led to the platen over the usual paper table 29 and is held against the platen to be advanced by the rotation of the latter by feed rollers 30.

Ordinarily, in order to cause the impressions of the type bars 24 to print on the under worksheets or strips, which, for convenience, will be 4indicated by the numerals 25a and 25h when referred to specifically, sheets of carbon paper are interposed between the several worksheets or worksheet strips, but these sheets require considerable handling, causing such inconvenience that many efforts have been made to obviate the need for them.

As in my prior application, this is done by the use of disks or wheels 31, which may be made of paper or other material impregnated with ink or coated with carbon or other transfer material. The entire disk 31 may be coated or impregnated, or, if desired, only an annular marginal portion thereof, the inner boundary of which is indicated 'by dotted lines in Fig. 2, may be so treated. In either event, as in my copending application above referred to, the carbon disks are supported at the printing point of the type bars 24 and have their marginal edges projecting between the worksheets 25, 25a and 25h. or any of the latter, so that when the type bar 24 prints upon the top sheet 25 through the ribbon 23, an impression will also be made on the sheets 25a and 25h by the transfer disks 31.

As disclosed in my prior application above referred to, each transfer disk is mounted in a bail which is fulcrumed at opposite sides of the typewriter and which may be swung up out of the way when desired. According to ,the present invention, however, and so as to permit one side of the typewriter to be free and unencumbered by the attachment of the present invention, the carbon disks 3l are each mounted near the loose end of a carbon arm 32, see Fig. 6. The carbon arms 32 near their other ends are mounted on a shaft 33 carried in a frame 34 and are spaced from each other by spacing washers 35. Each carbon arm 32 has an extension 36 beyond the shaft 33 normally urged downwardly by a spring 3'1 and therefore has a tendency to raise the disk supporting end of the arm 32 and carry the disk 31 out of the line of writing, as indicated by the most rearward carbon arm and disk in Fig. 5. When, however. the carbon arm and disk is intentionally depressed so as to enter the line of writing, the extension 36 of that arm is engaged by a latch 38 and held in that position. The latches 38 are pivotally mounted on a rod 39 and are urged toward operative position by springs 40. The upper ends of the latches 38 are provided with numbered ngerpieces 41 which may be canted, as has occurred to lever No. 4 in Fig. 12, to release the extension 36 and allow the carbon arm 32 and disk 31 carried thereby to rise and remove the disk from the line of writing-this being a non-print position of the carbon disk.

So far as its carbon arm carrying function is concerned, the carbon arm frame 34 could terminate adjacent the shaft 33. However, to form a handle by means of which the frame may be swung in manners and for purposes hereinafter referred to, to form a protective casing for the `carbon arms in use, to carry means for controlling the position of the carbon arms relative to the writing line, and, for holding the worksheets together at the printing point, the frame 34 is provided with two long arms 42 and 43 extending to the printing point of the machine. The carbon arm frame is also pivotally mounted on the shaft 33 which is carried in an arm 44 having a square or other noncircular extension 45, see Fig. 13, wherein this is accomplished by having the shaft 33 threaded in a shaft 44 and provided with a should-er 46 engaging the arm 43 of the frame fitting in a supporting bracket indicated as a whole by the reference numeral 47.

Thus it will be seen that the carbon arm frame 34 with the carbon arms 32 and disks 31 may be swung as a unit upwardly out of the line of writing and completely out of the way of the typewriting machine and, of course, it may be swung from this out-of-the-way position down to position for writing. In its lower or operative position, the carbon arm frame is held at a predetermined height by means which, according to the present invention, engages the platen 20 of the typewriter. When the disks are in operative position, the letter-feeding movements of the platen and the paper carried thereby will cause the disks 31 to each roll down into the line of writlng and remain interposed between two adjacent worksheets 25. On the return of the carriage, after the paper has been line-spaced, the disks can again roll, but this time in the reverse direction, through the line of writing and are brought at the end of the carriage return operation to position to receive the next impression through the type bars 24.

In my prior application above referred to, the transfer disks roll back and forth in the line of writing at a predetermined depth with relation thereto. After the transfer material of the portion of the disk utilized, while the disk was at this definite depth, became consumed and made weak impressions, the operator would make an adjustment to increase or decrease the depth of the disks relative to the line of writing so as to bring a fresh annular zone on the carbon disk into use.

Moreover, with this arrangement, there being nothing to avoid it, each time the carriage was returned the same point on the disk would be located at the printing point the disk rolling as much in 4one direction as another. Accordingly, ii.' greatest efliciency was to be obtained the disk would have to have a circumference substantially equal to the length of the line of writingotherwise there would be an unused portion on each disk when the other portions became consumed.

This is avoided by the present invention by causing the carbon disks to oscillate vertically as well as rotate during the letter-space movements oi' the carriage and by preventing oscillation but permitting rot'ation if desired during the return movement of the carriage.

This is accomplished by providing the arm 43 of the carbon arm frame with an eccentric roller 48 carried on a boss 49 on the arm 67. The arm 67 is adjusted, in a manner hereinafter referred to, so that the roller 48 rides on the top surface of the cylindrical platen 20 and, as the platen travels with relation to the carbon arms and the printing point of the machine, the roller 38 causes the carbon arm frame 34 to be raised and lovv ered, the frame 34 pivoting during this motion on the shaft 33,

During the return travel of the carriage, however, rotation of the roller 48 is prevented by a ratchet wheel 50 carried by it. see Figs. 4 and 5, which is engaged by a dog 51. Hence, as indicated diagrammatically in Fig. 2, the center oi the disk 31 follows an irregular path, indicated by dot-and-dash lines provided with arrow heads, during the rotation of the roller 48 while the carriage is feeding toward the left. and in a straight line from wherever it happened to be stopped by the dog 5l when the carriage is returned toward the right. f Thus the relative positions between the platen and the disk 31 become changed at the beginning of each new line and in this way the entire usable surface of the disk is employed.

It should be understood that in the matter of regulating the positions of the transfer disks relative to the line of writing by means engaging the platen, in the broader aspects of this invention it is immaterial whether an eccentric wheel, a plain concentric wheel, or a shoe, be used for this purpose. The eccentric wheel distributing the wear of the disk as above described is preferable.

When initially placing the transfer disks 31 between the worksheet strips 25. it is'desirable to have considerable looseness between the strips 25, although. while typing. this looseness, if still present, might cause air pockets to be formed between the worksheet strips and the carbon disks with the result that typing might be blurred. To obtain the `advantage and avoid the disadvantage just referred to, the front arm 42 of the carbon arm carrying frame is provided with a. pair of spring lngers 52 normally biased to move outwardly away from the web but held inwardly toward the uppermost worksheet 25 by an arm 53 pivoted at 54 and having a flat portion 55 engaging the spring arms 52V where they adjoin. By raising and lowering this arm 53 the operator may provide or remove looseness between the strips 25.

As shown inFig. 17, the paper ngers 57 and 58 and the movable paper fingers 52 'are carried by a block 54a having an edge 54h in contact with an edge 42a of the arm 42 of the frame 34 which extends down in front of the lworksheets. The block 54a is secured to the arm 42 by a screw 54e passing through an ear 42h on the arm 42 and threaded in' the block 54a. The block 54a is slidable vertically relative to the arm 42 for the purpose ci raising and lowering the ngers 52 and 5'? relative to the line of writing, and to permit this the ear 42h may be provided with a slot 42e in which the screw 54o may ride when the latter is loosened. To adjust the paper guide device. including the block 54a which carries the `various parts. the screw 54e is loosened, the block 54a moved up or down as desired, and then the screw 54o is tightened to hold the block 54a in adjusted position. i

To avoid the leading edge or other portions of the paper. such as the line of transverse perforatiohs 56. catching onto the arm 42 when the paper is advanced, the end of the arm 42 may be provided with depending paper lingers 57, and thse may be formed integral with an upwardly extending ilnger 58 which tends to hold the worksheet strips from falling forwardly. In fact, the fingers 52 may, as shown, be formed integral with the fingers 57 and 58, but only the fingers 52, in the preferred form of the invention, are made movable toward and from the worksheets.

The carbon disk 31 is mounted on the carbon arm 32 as showr in Figs. 6, 'I and 8. Each carbon disk -has a central aperture 59 adapted to nt onto a stud 60 carried near the end of the arm 32. On this stud there is a downwardly projecting ringer 61 terminating in a point 62 lying close to the lower edge 63 of a metal disk 64 carried by the end 65 of the carbon arm 32. To apply the carbon disk. it is slightly bent as shown in Fig. 8 so that the end 62 of the nger 61 may pass through the aperture 59. I'he disk is then drawn upwardly until the aperture clears a. slight upwardly extending projection 66 on the nger 61 to the position shown in Fig. 7. If in this position it is allowed to fall by gravity, the disk will be prevented from slipping ofi' the stud or bearing 60 by the projection 66. In actual operation. the thrust of the disk 31 on the stud 60 is upward and thus, with the finger 61 preventing it. there is no danger of the disk falling oil the pin forwardly. When out of contact with the paper. however. there is no thrust on the disk except the force of gravity and. should the disk tend to fall forwardly off the stud, this would be prevented by the projection 66.

It should be noted that while there is usually one carbon arm and disk for each carbon copy which is to be made of the work done or the original or uppermost sheet or strip, it is within the purview of this invention to have two arms and two disks for any or all oi.' such copies. This is shown in Fig. 5. in which there are two disks 31 and 31abetween the worksheets 25a and 25h. This arrangement may be employed when it is desired to have the impressions on the copies made in diierent colors at diierent times. For instance, one carbon disk may give a black impression while the other gives a red. This can be accomplished merely by pressing the control button 41 for the arm carrying the black disk 31 to release it and allow the disk to be moved up by the spring 37 and at the same time manually press the arm 32 carrying the red disk 31a down into operative position.

It will thus be seen that by the present invention a bichrome printing arrangement is effected and further that non-printing may be effected merely by pushing the buttons 4l to allow the carbon disks to be raised out of the line of writing.

In order to adjust the device to the platen of the particular typewritier with which it is used. instead of the eccentric 48 being carried directly on the arm 43, it is mounted on a separate arm 67 pivoted on a screw 68 carried by the arm 43 and it is clamped to the arm 43 in adjusted position by a screw 69 in the arm 43 riding in a slot 70 in the lever 67. If the platens of all the machines with which the attachment is to be used were of the same diameter and the lines of writing were at the same distances from the tops of the platen, this adjustment would not be needed.

As above stated, the carbon-arm frame 34 is secured to a shaft having a noncircular extension 45 and this is mounted in a fitting 47 o a supporting structure. This will now be described.

The vertical standard 72 has a vertical extension 71 preferably in the form of a tube cast therein and of noucircular formation, preferably square, which extends into and is clamped within one half 73 of the tting 47. The portion 73 of the fitting has a vertical slot 74 therein and also has screw-threads 75 by means of which a cap 76 is applied to the part 73 to close the open side of the slot 74, and also to form a bearing for a clamping screw 77. the inner end of which engages the vertical supporting tube 71. By loosening the screw 77, the tting 47 may be raised and lowered on the supporting frame 72.

The part 73 of the fitting 47 also has a stud 78 which has a bearing in the other half 79 of the fitting, so that the two parts of the tting may rotate relatively. The end of the stud has a washer 80 secured thereto and between the washer 80'and a ange 81 on the part 79 there is interposed a spring 82 which tends to draw a shouldered portion of the part 73 against the part 79 to yieldingly resist rotation of the halves 73 and 79 of the fitting 47, and also .to take up any wear which may occur between these parts.

The part 79 of the fitting also has a slot 83 therein and the open side of this slot is closed by a cap 84 similar to the cap 76 of the part 73. This slot receives the noncircular extension 45 of the carbonfarm supporting arm and it is held in the part 79 of the fitting by a screw 85.

Thus it will be seen, that the carbon-arm frame 34 may be swung in a vertical plane on the shaft 33, and then with its extension 45 may be swung upwardly and backwardly about the center of the fitting 47 to the position shown in dotted lines in Fig. 3. where it will be entirely out of the way, the portions 73,:1nd 79 of the tting rotating relatively for this purpose.

In order to stop rotation of the carbon-arm frame in the positions shown in full lines and dot-and-dash lines in Fig. 3. the part 73 of the litting 47 is provided with two pins 86 and 87 between which a pin 88 on the part 79 may operate. In the normal position of the carbon-arm frame 34, the pin 88 rests against the pin 86. but. when the carbon frame 34 is moved upwardly and rearwardly and assumes a horizontal position. the pin 88 engages the pin 87. Y

From the above it will be observed that when the supporting tube 'Il is located at a certain place with relation to the typewriter, which place depends somewhat upon the particular structure of the typewriter to which the device is applied,

the carbon-arm frame 34 may be adjusted vertically by loosening the screw 77 and sliding the tting 47 up and down. It may also be adjusted backwardly and forwardly by loosening the screw and sliding the square tube 45 relative to the fitting 47. Thus, the fitting 47 constitutes a universal union for securing the tubes 45 and 71 together in the desired relationship and, besides this, forms a pivot point about which the carbon-arm frame may be swung.

The supporting means for attaching the standard 72 and its vertical tube 71 to any of the diierent maires of front-strike typewriters now on the market is shown in Figs. 1 and 3. The main portion of this clamping bracket comprises a frame 89 extending from front to back and adapted to be located at one side of the typewriter. At the back end, this frame has a hook portion 90 which engages under a lower side rail 91 of the typewriter. At its front end the frame 89 has an arm 92 adapted to hook under and engage the front portion of the rail 91. The arm 92 is adjustable backwardly and forwardly with relation to the frame 39 and is held in adjusted position by a pair ol nuts 93. one below the arm 92 and the other above the frame 89. and said nuts being carried by a threaded rod 94 passing through aligned elongated slots in the frame 89 and arm 92.

The threaded rod 94 extends upwardly and at its upper end carries a block 95, see Fig. 18. having an inverted U-shaped horizontal slot in which a U-shaped bar 96 slides. The bar 96 may have any shape desired-the U-shape shown being employed for the purpose of strengthening it. At one end 97 the bar 96 is adapted to rest upon and engage some part 98 of the typewriter frame. In the construction shown, it rests upon the top plate at the forward part of the machine. This top plate is usually provided with a depending flange 99 and the bar 96 has a clamping block 100 slidably mounted in depending arms 101 and having a v-shaped track 102 engaged by V-shaped projections on the block 190. The sliding block has a hook 103 which may be drawn up under the flange 99 by means of a draw screw 104 cast in the clamping block 100 and drawn upwardly by a nut engaging the top surface ofthe bar 96.

In adjusting the supporting device to a typewriter, the arm 92 is so placed on the frame 89 that the hook` on the arm and frame may engage the side rail of the typewriter. '171e threaded rod 94 is then placed in such a position backwardly or forwardly on the frame 89 that its clamping block 100 may engage a suitable p0rtion of the typewriter. The nuts 93 are then tightened to secure the arm 92 and frame 89 together. 'Ihen the block 96 is slid toward or from the threaded rod 94 to bring it to desired position, after which the nut 105 is adjusted to draw the hook 103 on the sliding block 100 into proper position. After this is done. a nut 196 carried by the threaded rod 94 and engaging the block 95 (which has a clearance hole 107 through which the rod passes) draws the frame 89 and arm 92 rtightly upwardly against the lower rail 91 of the typewriter. v

The standard 72 and its tube 71 could be earried directly by the clamping bracket frame 89 for most purposes. However, in order to make the device universal for all kinds of front-strike typewriting machines, further horizontal and vertical adjustments are provided.

For this purpose the standard 72 is providedwith a horizontal portion 108 adjustable relative to an L-shaped bracket 109 in a horizontal plane. These parts are adapted to be secured together in adjusted position by a bolt 110. 'I'he L-shaped bracket 109 is mounted in a vertically disposed slot inl the frame 39 and is held in vertically adjusted position by a. clamp 111 carried by a threaded stud 112 threaded or cast in the bracket 89 and carrying a nut 113 by means of which the clamp may engage and rmly hold the L-shaped bracket to the frame 109, the L-'shaped bracket being provided with an elongated slot 114 to permit its vertical movement relative to the stud 112.

The typewriter herein selected for the purpose of illustrating the invention is of the kind wherein the platen moves step-by-step to carry the worksheets across the printing point of the machine. However, it should be understood that the various features of the present invention apply equally weil to a kind of machine such as a teletype typewriter, wherein the type basket travels relative to the platen.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
