APPARATUS FOR PRODUCING IMITATION TYPE-WRITTEN LETTERS.

Specification of Letter s Patent.

Patented Dec. 30, 1913.

Application filed. July 22, 1912. Serial No. 710,822.

To all whom it may concern:

Be it known that I, JAMES A. LooKwoon,

a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Apparatus for Producing Imitation Type-lVritten Letters, of which the following is a specification.

My invention relates to a novel apparatus for producing imitation typewritten let ters and its principal object resides in the provision of a mechanism of simple construction which may be readily attached to an ordinary job printing press and which operates to impart to impressions made from the type on the press, the ribbon effect which is desirable in the production of imitation typewritten letters or circulars.

Another object of my invention is to provide in association with the apparatus, means whereby the letter-head and the body of a letter are printed simultaneously respectively without and wit-l1 the ribbon effect and, if desired, in different colors. I attain this object by the mechanism illustrated in the accompanying drawings in the various views of which like parts are similarly designated, and in which,

Figure 1, represents a side elevation of an ordinary job printing press to which my attachment has been applied, part of the crank wheel having been broken away, Fig. 2, a fragmentary section along the line 22, Fig. 1, looking in the direction of the arrow A, and drawn to an enlarged scale, Fig. 3, a similar section taken along the same line but looking in the direction of the arrow .0, Fig. 4, a section taken along the line Fig. 3, and Fig. 5, a section taken along the line 5-5, Fig. 3.

In the drawings, 2 designates the sta tionary frame or body portion of a job printing press of ordinary construction, 3 the oscillatory frame which carries the chase 4 and the ink distributing disk 5, 6 the oscillatory member which at its end supports the inking rollers 7, 8 the crank wheel which by means of a pitman 4C0 imparts a reciproeating movement to the frame 3, and 9 thetympan plate or platen which in the operation is actuated by a cam 10 to press a sheet of paper fed thereonto from the feed table 12, against the type arranged in the form 13 which is held in the chase on the oscillating frame.

My attachment consists of a standard 1 1 which is adapted to be supported and fastened upon the floor in adjacency to the press and which at its upper extremity has a laterally extending arm 15 the end of which is turned downwardly to provide a support for a non-rotary shaft 16 whose opposite end is fixed in an opening in the upright body portion of the standard.

Loosely mounted on the shaft 16 is a winding spool 17 the circular end-flanges 18 of which are peripherally toothed. An arm 19 pivotally mounted between two collars 20 on the shaft, carries a feed pawl 21 in engagement with the teeth of one of the flanges l8 and it is connected with a downwardly extending rod 22 on one of the collars by means of a coiled spring 23.

A second pawl 24 mounted on an arm 25 which is fixed on the shaft 16, engages the teeth of the opposite flange 18 for the purpose of preventing retrograde movement of the spool 1?. Attached to the outer end of the pivoted arm 19 is a cord 26 which being rove through two rings 27, respectively secured on the arm 15 and on the upright portion of the standard, is connected at its opposite end to a collar 28 which is adjustably secured around the pitman 450 of the press.

An inked ribbon 29 of the character used on typewriting machines but of larger proportions, is wound upon a spool 30 rotatably supported between two plates 31 which are vadjustably secured at opposite sides of the stationary frame 2 of the press, and the opposite end of the ribbon which extends between the platen 9 and the chase 4 on the oscillatory frame 3, is secured to the windns po IVhen in the operation of the press the type-holding element and the platen are moved together to produce an impression on a sheet of paper held upon the latter, the ribbon 29 interposed between the said sheet and the body of type secured on the said element, will cause the impression of the type to be produced on the paper in exact imitation of the work of a typewriting machine and without the aid of the inking mecha nism of the press. After each impression, the oscillating frame 3 moving away from the platen causes by means of the cord 26, an upward movement of the arm 19 against the action of the spring 23 with the result that a determinate port-ion of the ribbon is fed onto the winding spool and a fresh part of the same is brought in engagement with the type when the next impression is being made.

When it is desired to print on a sheet of paper a letter-head at the same time that the body of a letter is being printed thereon, a ribbon is used whose width corresponds with the length of the body of the letter, as is shown in Fig. 2 of the drawings, in which the position of the ribbon with relation to the type in the form 13, has been shown by broken lines 32, the type in the form from which the body of the letter is printed, having been designated by the numeral 33 and that which produces the letter-head by the numeral 3%. The composition around the cores of the inking rollers T has been eliminated with the exception of two portions 35 and 36 at opposite ends thereof, one of which is of a width equal to the height of the letter-head for the purpose of inking the same during each movement of the oscillatory frame of the press, while the other serves to keep the rollers from binding by engagement with an edge of the chase beyond the opposite end of the form.

Inasmuch as the type of the letter-head is not engaged by the ribbon while the impression is being made and the type of the body of the letter is not engaged by the inking rollers, it will be seen that in each impression of the type in the form the letter-head will appear as usual, while the letter itself will have the appearance as if it had been written on a typewriting machine and by supplying the ink rollers with an ink of a color diiferent from that with which the ribbon is prepared, the letter-head and the body of the letter may be printed simultaneously in different colors.-

After the entire length of the ribbon has been unrolled from the spool 30 and wound onto the winding spool 17, it may be rewound on the first mentioned spool by applying a crank to one of its trunnions by which it is supported on the plates 31.

Having thus described my invention what I claim and desire to secure by Letters- Patentis:

1. The combination with the platen and the moving type-holding element of a printing press, of a standard separate from the latter, a winding spool rotatably mounted on said standard and including a toothed wheel, a spring-impelled arm pivotally mounted on the standard, a pawl on said arm in engagement with the teeth of said wheel, and a cord connecting said arm with a part of said element.

2. An attachment for printing presses comprising a movable independent support, a winding spool and mechanism for rotating the same, mounted thereon in cooperative relation to each other, means for the direct cooperative connection of said mechanism with a reciprocating member of a printing press, a second spool, means to rotatably attach the same to the frame of a printing press, and an inking ribbon wound on said spools.

3. An attachment for printing presses comprising a movable independent support, a winding spool and mechanism for rotating the same, mounted thereon in cooperative relation to each other, a cord for the operation of said mechanism, a clamp on said cord for its direct connection with the pitman which in the operation of the press converts the rotary motion of the driving shaft thereof into an oscillatory movement of the type-carrying frame of the same, a second spool, means to rotatably attach the same to the frame of a printing press, and an inking ribbon wound on said spools.

In testimony whereof I have afiixed my signature in presence of two witnesses.

JAMES A. LOCKWOOD.
