LINE -FORMING ATTACHMENT FOR TYPEWRITERS Arthur F. Becan, Bayport, N. Y.

Application May 27, 1947, Serial No. 750,771

4 Claims. (Cl. 197-113) This invention relates to typewriters, and more particularly to attachments adapted for use with typewriters, whereby vertical and horizontal lines can be disposed upon the paper within the typewriter.

It is an object of the present invention to provide attachments for typewriters which will make vertical and horizontal lines quickly and easily upon the paper within the typewriter, and which have particular use for the forming of lone lines on the sheet without the continual striking operation which is necessary in effecting such long lines with the present underline key of the typewriter.

It is another object of the present invention to provide an attachment for typewriters which will form dotted lines extending both vertically and horizontally.

To effect these objects, additional type arms are added to the typewriter, or business machine, in available space upon the machine depending upon the model of the machine, such space being readily found at the side of the last type arm at either the right or left side of the typewriter. These arms are attached to be pivoted from the same part of the machine in the same manner that the type key arms are pivoted. In lieu of type on the arm there is provided a modified miniature version of a ball point pen adapted to have replaceable cartridges for supplying the ink material to the ball and to form continuous vertical and horizontal lines when the arm and the ball point are brought into engagement with the sheet within the machine. Another arm carries two small toothed wheels, or styli, one to revolve on a horizontally extending axis to provide a vertical dotted line, and the other to revolve on a vertical axis to provide a' horizontal dotted line. These dotted lines are used in stencil work, and are formed by the actual cutting or punching of the paper. Aline key is provided with the neces- 'sary mechanism to cause the ball point pen to be pivoted from its normal resting position and firmly pressed against the sheet within the typewriter. Mere horizontal movement of the carriage of the typewriter quickly and easily causes the desired horizontal line to be drawn upon the sheet and the rotating of the platen quickly produces a vertical line. The typewriter ribbon will remain in lowered position at times when the ball point pen and toothed wheel are being used since the use of the new type arms will not effect a simultaneous raising of the ribbon for employment as is done by a coordinated action in the-use of the standard type arms. A release key is disposed adjacent the line key which effects a release of the arm and return of the arm to its normal or inoperative position.

Connections are made with the standard ribbon bar to effect automatically the drive coupling connection of the toothed wheel arm with the operating key or the ball point pen arm with the operating key at the same time that the standard ribbon lever is set for either stencil or normal typing positions. With the standard ribbon lever set in stencil position, depression of the new line key operates the toothed wheel styli arm to be employed for stencil work while with the standard ribbon lever set for normal typing, depression of the new line key operates the ball point pen arm to be employed. In use of the toothed wheel arm. the standard shift lock key will be depressed, as in normal typing procedure, to cause the upper character or vertical wheel to be engaged in the event it is desired to cut a vertical dotted line.

For other objects, and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure l is a side elevational view of a portion of a typewriter with a portion broken away to show the application thereto of lining means illustrative of the invention.

Figure 2 is a perspective view of an improved lining means adapted to be operatively associated with a typewriter.

Figure 5 is a side elevational view of a modified form of ball point pen.

Referring now particularly to the figures, I0 represents a typewriter having a frame supported upon the usual feet I l and provided with a forwardly extending keyboard [2, a conventional carriage, not illustrated, movable transversely of the frame and a rotatable platen carried by the carriage. Connected to opposite sides of the typewriter and extending upwardly are brackets l3 and [4. Each of these brackets is made in two parts, one part being shown at [5 and the other part at It. The part l5 can be adjusted relative to the part It by the provision of slots H in the part It and clamping bolts i8 extending through the slots and adapted to be secured at any station along the height of the slots. Bolt holes l9 are provided in the part l6 for the attachment of the brackets to the typewriter frame l0. At the upper end of the bracket part l are openings 2| and 22 through which can be extended shafts 24 and 25. These shafts extend transversely across the full width of the typewriter. The shaft 24 can be longitudinally and rotationally adjusted through the openings 2| of the bracket parts |5. The shaft 25, however, is fixed against axial displacement by collars 26 abuttingthe faces of the bracket parts l5.

To the shaft 25 there are aihxed axially spaced pinion gears 28 and 29. On the shaft 24 there are connected axially spaced pinion gears 3| and 32, adapted to be respectively brought into mesh with the gears 28 and 29 of the shaft 25. Since the shaft 24 is axially adjustable, the gears likewise will be adjustable, and either the gear 32 will be placed in mesh with the gear 29, or the gear 3| will be placed in mesh with the gear 28. The gear 3|, however, rotates upon the collar 33, so that when the gear 3| is in mesh with the gear 28, the gear 3| will be rotated without effecting the rotation of the shaft 24. The gear 32 may be similarly connected to its collar, but this is not necessary.

At the right side of the machine is the standard ribbon bar 34 on common machines, forward and rearward movement of which is controlledby setting the standard ribbon lever of the machine in either stencil or typing positions. Placing the standard ribbon lever in stencil position causes a forward movement or shift of the bar, and arm 35 is pivoted forwardly about a pivot point 38 on a bracket 31 extending from the bracket part l5. Coupled to the arm 35 is an arm 38 having a forked formation 39 at its outer end adapted to extend over the shaft 24 to engage collars 46 and 4| thereon. With the bar 34 moved forwardly or to the right as viewed in Figure 2, the forked formation 39 will abut the collar 4| and cause the shaft 24 to be moved to the left and to take with it the gear 3| and place the same in mesh with the gear 28, and at the same time unmesh the gear 32 from the gear 29. This will make possible the use of a dotted line device 42, whereas in the position as shown and before the gear 3| had been shifted the arrangement was such as to effect the operation of a ball point pen device 43.

The dotted line device 42 comprises an arm 44 having a head formation 45 at its upper end adapted to contain two toothed wheels 46 and 41. The wheel 46 is disposed within a slot 48 in the upper end of the head formation 45 and in such a manner that the wheel may rotate about a horizontal shaft 49 extending between the sides of the slot or opening 48. This wheel 46 will be used at times when it is desired to place a dotted line upon the sheet in the typewriter which extends in a vertical direction. With the arm 44 brought into a position to effect this result, the same can be done quickly by simply rotating the platen containing the paper sheet. The arm 4| is pivoted upon a pin 5| carried upon some part of the typewriter, such as the typewriter part upon which the conventional type bars are pivoted. Below this pivot a link 52 is pivotally connected to arm 44 at 53, which will serve to pivot the arm upwardly on its pivot pin 5|, this link connecting at 55 to an arm 54 extending from the gear 3|. When the gear 3| is in mesh with the gear 28 and the shaft 25 is rotated, the gear 3| will be rotated and the arm 54 thereof will be brought, downwardly to cause the arm 44 to be brought upwardly and into engagement with the sheet within the typewriter.

The wheel 46 and the wheel 41 may be selectively positioned for operative contact with a paper sheet or stencil in the typewriter by operation of the conventional type bar shift lever 11 which is effective to relatively move the typewriter platen and the pivotal support for the type bars to bring different parts of the type bar striking ends against platen carried paper.

The wheel 41 is carried upon a shaft 58 extending vertically through the notch 56. At times when it is desired to have a dotted horizontal line, the arm will be brought upwardly and the carriage of the typewriter will be slid across the typewriter frame, whereupon the wheel 41 will be operated and dotted impressions will be made upon the sheet.

On the pinion 32 is an arm 6| connected by a link 62 to the ball point arm 63 forming a part of the ball point device 43. This link is con- :nected to this arm, as indicated at 64, and the arm in turn is pivoted upon a shaft 65. When the gear 32 is in mesh with the gear 29, as shown. and the shaft 25 is rotated, the ball point 66 will engage the sheet in the typewriter.

The ball point pen device 43 includes a cartridge formation 61 adapted to be removably attached to a head 68 on the arm 63 and upon a threaded projection 69 provided for the purpose. The cartridge 61 is screwed down upon the threaded projection 69 and is retained thereon against turning movement by a cotter pin 1| extending through a slot 12 in the threaded projection 89 and through holes in the cartridge sleeve 61. The upper end of the cartridge has a guide arm 13 securely attached thereto to guide the ball point device over the typewriter platen.

Referring now particularly to Figure 5, there is shown a modified form of the ball point cartridge wherein the cartridge, as indicated at 14, is retained in a horizontal position upon the top end of a specially formed arm 15. The screw cap 16 provides access for replenishment of ink supplyin cartridge form.

Coming now to the device for effecting the rotation of the shaft 25, there is provided a lateral extension 8| on the bracket part If; at the left side of the typewriter. The outer end of the projection 8| is bent upwardly, as indicated at 82, and carries a notched vertically extending plate 83. This plate may be adjustably secured to the extending formation 82, if desired. This plate 83 has a plurality of notches 84 adapted to be engaged by a projection 85 on a depending arm 86 of the line key 81. The line key is pivotally mounted on the release key 89 by a pivot pin .88 above the point where the teeth or notches :84 are engaged by the projection 85. As the key 89 is brought down by the key 31 against a stop :92, which may be adjustably connected to a formation 93 upon the projection 8|, the shaft 25 to which the key 89 is secured at 9| will be rotated. The key 89 in its engagement with the stop 92 will be cushioned by a spring 94 which will aid the return of the key 89 to its normal position raised above the stop 92. As the shaft :25 is rotated by keys 81 and 89, the respective devices 42 and 43, depending upon which one has been selected, will be brought to bear against the sheet of paper in the typewriter carriage.

In order that the keys 81 and 89 may be held down without the requirement of manual labor, the arm 86 is arranged so that its detent formation 85 will engage one of the notches 84. After the line has been formed, the release arm 89 can be slightly depressed so as to release tension at the point of engagement of detent 85 with the notch 84 and permit a tension sprin 96 to return the line key arm 81 to a position wherein the detent 85 will be out of engagement with the notch 84. The spring 96 is connected, as at 91, to the rear end of the key arm 89 and is connected at its opposite end, as indicated at 98, to a formation 99 on the rear end of the line key 81.

It should now be apparent that there has been provided an attachment for a typewriter whereby vertical and horizontal lines can be formed upon the sheet within the typewriter carriage with ease and in an expeditious manner. It should also be apparent that the attachment has made use of the standard ribbon release arm or ribbon bar to effect the selection of one or the other of its devices.
