TYPE-WRITER AND COLOR ATTACHMENT FOR PLATEN-PRESSES.

Application filed. January 22, 1917.

To all whom it may concern Be it known that l, WILLARD lt. Disson- BOURG, a citizen of the United States, residin g at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Typell riter and. Color Attachments for llaten- Presses, of which the following is a specification.

This invention relates to printing machinery and particularly pertains to a multigraph attachment for platen presses.

One leading object of this invention is to provide improved means for doing n1ultigraph work on a platen press, and another leading object is to provide improved means for doing multieolor work, including multigraph work, on a platen press.

it is often found desirable to reproduce a typewritten letter or other copy in a rapid and inexpensive manner and to give it the appearance of having been an original copy made upon a typewriter. It is one of the objects of this invention to provide an attachment for platen presses which will make it possible to use the press in the rapid production of such copy and to give it all the characteristics of an original sheet individually written upon a typewriter.

. Another object of this invention is to provide means embodied within the attachment whereby a letter head, the body of the printed matter, and the signature or other added matter may be simultaneously placed upon a sheet and printed in various colors as desired.

Another object of this invention is to provide an attachment for platen presses of the above character which may be readily mounted upon the press and operated there by without alteration of the various parts of the frame or mechanism and in a manner to r iquire but slight change in the arrangement of the existing parts.

Another object of this invention is to pr0- vide a positively acting feed mechanism by which an inking ribbon is fed over the type and which is operated by the normal movement of the press without the use of other actuating mechanism.

rlnother object is to provide easily adjusted means for changing the feed of the ribbon as deemed suitable for various type.

another object of the invention is to provide simple and easily operated means for Specification of Letters Patent.

reversing the direction of movement of the ribbon when desired.

Another object of this invention is to utilize the present inking disk to'supply part of the type with ink wlthout interferiiw with the body of the letter, and also to utilize the inking roller saddles and their shafts without alteration.

Another object of the invention is to provide an attachment for platen presses which will permit two or more colors to be printed upon a sheet simultaneously and in any po sition upon the page.

It is a furtherobject of this invention to provide an attachment for printing multicolored duplicate letters and other copy which will be simple in its construction, direct in its action, and adapted to positively and continuously operate in synchronism with the present planten press mechanism.

Other objects will appear hereinafter.

Referring more particularly to the drawings, 10 indicates the body of a platen press, which is of any desired design, and is here shown as formed with a suitable table 11 and a platen 12. A form or type-bed frame 13 is pivotally mounted for vertical movement upon a pivot shaft 1-1 and suitable actuating mechanism draws it and a type bed carrying a type form 15 against the platen when printing. Mounted above the form and upon the frame is an inking disk 16 over which a series of inking rollers are normally adapted to pass. These rollers are rotatably mounted within saddles l7 and 18 at each side of the disk and the saddles in turn are supported upon saddle rods 19 and 20 resiliently mounted within the roller frames 21. These frames are adapted to be oscillated around a pivotal point of rotation by suitable mechanism which causes them to carry the inking rollers over the face of the inking disk 16 and downwardly over the face of the type in the form, after which the rollers are returned by the same mechanism. The mechanism thus far described constitutes the general construction of platen presses in common use and does not f'orm'any part of the present invention except in combination with the attachment which will be hereinafter described.

The main portion of the attachment concerned in the present invention resides in a feed mechanism 22 for an inking ribbon 23. This mechanism comprises a pair of magazine rollers 24 and 25 which are dotachably mounted in parallel relation to each other between sets of mounting disks 26 and 27. The disks 27 are formed with fixed studs 28 which extend inwardly and are seated within sockets in the ends of the rollers. The opposite ends of the rollers are fitted with sockets within which springpressed studs 29 are adapted to be held by springs 30. These studs 29 are fitted with knobs 31 by which they may be withdrawn from engagement with. the rollers and permit their removal. These rollers are adapted to be alternately actuated by the operating niechanism and are fitted with spur gears 32 and 33, respectively, by which they may be separately driven. A reversing ratchet criving gear 31 is mounted between the gears 32 and 33 and by movement of a control lever may be swung in an eccentric manner to engage either of the gears as desired. This driving mechanism is mounted upon a detachable frame member 36 which is similar in design to a frame member 37 disposed at the opposite ends of the rollers. These frame members are formed with horizontal slots 38 adapted to part ially encompass an extending ledge which normally occurs upon the form or type-bed frame of a platen printing press. Set scrcws 39 extend upwardly through threaded openings in the bottoms of the frames 3i) and 37 and provide effective clamps by which the two parallel frame members may be held in rigid detachable position upon the ledge of the press. Each of the frame members is further formed with an upwardly and forwardly extending roller supporting arm in between which an idler or guide roller 11 is supported upon a shaft 42. This roller is disposed with its periphery in tangent ial relation to the face of the type form and acts as a support and guide for the ribbon 23 which passes down over the face of the type from magazine roller 25 and returns over an idler or guide roller 13 to magazine roller 21. The ribbon here referred to is a typewriter or multigraph ribbon of a width corresponding to the length of printed matter adapted to be imitated in typewriter type upon the sheet.

The feed mechanism of the magaz'zine rolls comprises the gears 32, 33 and 34-. and an actuating mechanism which consists of an oscillating lever arm 1-4, which is mounted upon the shaft of the gear 34-. This arm extends upwardly and normally is held in a position toward the forward end of the printing press by means of a tension spring This forward movement is limited by a. stop pin iii. The free end of the arm is fitted with a bolt 4-7 which pivotally secures a substantially horizontally disposed adjusting bar 48. the outer end of the adjusting bar being supported by a vertically swinging actuating arm 49. This arm extends downwardly and is pivoted upon a pivot pin 50 mounted within a C'clamp 31. by which the arm may be detachably secured to the frame of the press. A second C-clamp similar to 51 is mounted at the other side of the press and the pivot .70 extends through the roller 43 to the second clamp, not shown. The arm 19 extends downwardly from the pin 50 and is adapted to be engaged by a transversely extending bar 52 which normally secures the roller frame members 21 to each other at their lower ends. It will thus be evident that when the roller frames are oscillated. the movement of the bar in the direction of arrow a will relieve the lower end of the swinging arm 19 and cause it to permit ill] till

rs-sash? movement of the oscillating arm ll in the direction of the arrow -b on Fig. and thereby advance the ribbon over the face of the type. Tn order to produce this ad vance movement, a pawl 53 is mounted upon the oscillating arm and normally held in engagement with the teeth of the gear 34: by means of a spring 54. A check pawl is mounted upon the frame member 36 and is held in engagement with the teeth of the gear 34x by means of a spring 56 and is so arranged as to prevent retraction of the ribbon after its advance.

its a means for adjusting the forward moven'ient or escapement of the pawl 53, the outer and under face of the bar 48 is formed with a series of semicircular serrations which are closed by means of a flat spring 57. These notches 57 are adapted to receive a pin 58 which is secured to the end of the swinging arm ll) and which may be selectively positioned in a desired notch to determine the length of stroke made by the oscillating lever 4A.

The inking ribbon is adapted to cover the type in the body of the type form and permit an imprint to be made against it and upon the sheet being printed. Tn case it is desired to simultaneously print the letter head and the signature, or other inserted matter, in the same or different color types, the normally used inking rollers are re moved from the press and sectional composition rollers 68 and 69 are substituted therefor, after which short steel. rollers 62 and 63 are placed upon the opposite ends of the roller shafts 59, and 61 and adjacent the saddles therefor. These steel. rollers are adapted to support the shafts in their normal position. In order to support the saddles and shafts throughout the length of their strokes, a pair of auxiliary supporting guides (Sal are secured to the type form frame and on a level. with the face of the present roller guides 65. The supplemental guides til extend rearwardly along opposite sides of the inking disk to a point above and in the rear thereof. lin this manner a frame guide and support is provided. the composition rollers 68 and 69 throughout the length of their travel over the disk. After the composition rollers have been mounted in position, the advance pawl 66 is drawn to a position of disengagement with the ratchet teeth 67 formed integral with the inking disk and therebeneath. In this manner rotation of the disk will be prevented and it will then be possible to apply ink to the disk in continuous surfaces extending the vertical width thereof. These strips of ink may be of different colors and are so placed upon the disk as to correspond to the position of the type within the form. As a means for distributing this ink upon the various parts of the type form, said rollers 68 and (39 are mounted upon the roller shafts and adjusted by set-screws 70 to cause them to roll over the desired ink and thereafter across the type to be thus inked. its indicated in the diagram disclosed in Fig. of the drawings, the sheet print-ed may have a typewritten body portion a of a color to be determined by the selection of the rib bon 23, a letter head --Z)- of any desired color, and a signature or footnote cof the same or a dil'lerent color. it will be further understood by examination of the structure here disclosed that innumerable variations in. the arrangement of the printed portions and their colors may be made by the use of the apparatus.

l Vl'ien it desired to print letters or other copy with the aid of the printing attachment here described, the type is set up, as desired, and thereafter the ribbon is positioned over the face of a certain portion of the type forn'i between ribbon guides or. as particularly disclosed in Fig. 13 of the. drawings, and over the supporting rollers l1 and i3. The pawl 66 is then thrown out of engagement with the ratchet teeth beneath the inking disk and thereafter the inking rollers are removed from their shafts. The roller supporting. guides (i i; are then. mounted upon opposite sides of the inking disk so that substitute rollers 62 and ()3 will. have a continuous bearing surface and support as inking rollers 68 and 69 move over the surface of the disk which is now doprived of its rotating mechanism and re mains stationary. The path of travel described by the rollers 68 and 69 across the face of the inking disk is then corered with a coating of ink of the color de sired, and the machine will be in condition for printing.

l issuming that the 'irinting press is in. the condition as illustrated in llig. l. of the drawings, movement of the actuating parts thereof will cause the type form to swing with its frame from the pivot pin 1-11: and away from the platen. Elimultaneous with this movement, the roller frames will. be oscillated. to swing dcuvnwardly and to pass the roller shafts 59, 60 and 61 with the inking rollers 68 and 69 over the face of the inking disk. As has been stated, this disk has been prm iously prepared and each of the rollers will be individually inked with ink of the same or different colors. The rollers will be supported by means of the steel rollers 62 and 63 upon the guide frame members G l which have been positioned along opposite sides of the disk. its the roller frames are swung downwardly, the inking rollers will pass over the face of the type and along opposite sides of the inking ribbon 23, in this manner supplying ink to the desired type without interfering with the inking ribbon or the type to be supplied Bilu.

with ink therefrom. At the beginning of the down stroke, the cross bar connecting the roller frames will move in the direction a and will relieve the lower end of the swinging arm L9 in a manner to permit oscillating lever n to be effected by the tension spring 45 and drawn in the direction of the arrow b*. This will cause the pawl 53 to engage the peripheral teeth of the gear 3% and rotate it a given part of a revolution, as determined by the position of the pin 58 in one of the notches 5'7. When the arm n encounters the stop %6 it will remain stationary and will cause the swinging arm 49 to remain stationary while the rocking frame swings outward and away from the lower end of the arm. As the roller frames and their cross bar return to their normal upright position, the swinging arm 4:9 will be encountered and will swing back to advance the pawl 53 the amount required for the next feed movement of the rollers. When the ribbon is entirely rolled from one of the magazine rollers, the lever 35 is swung a half revolution and will cause the gear 34.- to en 'age the opposite gear and actuate the opposite roller, thereby insuring the empty ribbon spool being rewound and the type properly inked. As the ink is removed from the inking disk by the rollers, it may be replenished as desired and thus a sheet may be printed in a single. operation and having several colors of print upon it.

It will thus be seen that the attachment for platen presses here disclosed provides easily and positively operated means for duplicating typewritten matter upon a sheet and to also print other printed matter in various colors upon the sheet as desired without the use of expensive mechanism nor the alteration of the presses in common use.

While I have shown the preferred con struction of my printing attachment for platen presses as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of my invention.
