Patented Aug. 10, 1937 UNITED STATES PATENT OFFICE MEANS FOR. BEPRODUCING INSQKIPTIONS AND THE LIKE 12 Claims.

The present invention pertains to a novel device for reproducing an original writing or drawing. The device is intended primarily, although not so limited, for reproducing a signature on a document such as a check, bond, insurance policy, or the like, where. a great number of duplications of the signature are required and where the possessor of the signature does not desire to spend the time that would be required for him to write his signature in each case.

The principal object of the invention is to provide a device oi this character that reproduces the signature, writing or drawing from an original master made by the author. The reproduc- 13 tions can then be made mechanically by a clerk. Another'object of the invention, is to provide a means and method of reproduction or transcribing wherein any possible alteration of the original in the process is reduced to a minimum.

Theoutstanding conception of this invention is the effect of mirroring an exact reproduction of character of signature or handwriting by the act of writing the signature itself.

In the accomplishment of these objects, the

writing or drawing is performed in the original on a fixed sheet beneath which are moved two or more strips at an angle to each other. A suitable medium, such as carbon paper, is provided between the strips and between the upper strip and the fixed sheet. The writing or drawing is thereby resolved into undulating and normally unintelligible components on the moving strips.

From these strips are produced matrices conforming to the undulating lines and also in strip form. To reproduce the original inscription, the matrix strips are run through the machine orone identical thereto. A writing instrument is guided by the intersection of the matrices and thereby reproduces the original inscriptlonon a sheet placed beneath the instrument.

A third strip is preferably made during the inscription, and a matrix produced therefrom. Such a third matrix, during transcription, passes continuously through the point of intersection of the other twoand continuously moves the writing instrument out of the angle of intersection, so that it cannot become wedged in that angle.

The invention lends itself to code writing inasmuch as the strips and matrices are individually unintelligible and cannot reproduce the original unless used in the original angular relation of the strips and at the same relative speed. Hence, this angular relation is an essential element in 5-the decoding process.

1936, Serial No. 98,3?3

The invention is iully disclosed by way of example in the following description and in the ac= companying drawings in which Figure l is a plan view of the machine, showing the original scribing operation; 5

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a plan view of the machine, illustrating the reproducing operation;

Figures 5, and 6 are sections on the lines 10 3-4, 5-5, and 6-t respectively of Figure 3, and

Figure 7 is a plan view of one of the strips with humps or risers applied thereto.

Reference to these views will now be made by use of like characters which are employed to 15 designate corresponding parts throughout.

In Figures 1 and 2 the machine is illustrated as comprising a bed or table I standing on legs 2. The body ofthe machine carries, in any suitable manner, pairs of opposed brackets 3 and 3' carrying pairs of opposed and parallel rollers 4. The line of travel of any pair of rollers, that is, the line drawn between the rollers of a pair, is at an angle to the line or travel of every other pair of rollers. Moreover, the lines of travel of the several pairs of rollers intersect one another in the proximity of the center of the table I. One roller of each pair has an extended shaft 5 carrying one or two gears 6, as required, for gearing the shafts together as illustrated in Figure 1. One of the shafts is driven by an electric motor I or other suitable driving means, whereby all the pairs of rollers are driven in synchronism.

Each pair of rollers is designed to carry and propel a strip which is preferably endless and passes over and beneath the bed i as shown in Figure 2. The strip may be also used as two rolls of photographic film for any length, dependent on its use. The several strips are designated by the numerals 8, 9, and ill in Figure 1. They are 40 preferably apertured at H along the edges to receive cogs l2 on the rollers for accurate feeding and propelling.

The brackets 3' are preferably slidably mounted in lugs I3 on the table and enclosed by springs 45 l4 between the outer lugs and the ends of hubs 15 in which the corresponding rollers are journaled. These springs exert a slight outward pressure on the hubs l5 and thereby maintain the strips in a taut condition. The legs 2 pref- 59 erably support also a base l6 carrying brackets l1 and idlers l8 mounted respectively beneath the rollers 4 for guiding the strips.

Because of the intersection of the lines of travel as stated above, the strips 8, 9, and I0 intersect one another over the bed ,I. Over the area of intersection is provided an open clamping frame I! located on studs 20' mounted on the bed I and not interfering with the several strips. 5 The frame may be clamped down by wing heads II on the studs 20.

The lower surface of the frame is designed to carry a fixed sheet of paper 32. The several strips I, I, and II pass beneath the frame and 10 beneath the sheet 3 2 at diiferent levels but in close proximity to each other. An inscription made on the sheet I! by a pen or other instrument 3! is transferred to the strips 8, 9, and II by a suitable transfer medium. Such a medium 15 may be, for example, sheets 34 of carbon paper inserted between the strips and between the upper strip and the sheet 32. The carbon sheets as well as the sheet 82' may be so shaped and perforated as to receive the studs 20 and there- 20 by he held in a fixed position beneath the frame ll.

The strips 0, s, and Ill may consist of paper, celluloid film or any other suitable material adapted to take a transfer of the impression 25 made by the instrument 33. Likewise, the transfer may be effected by any suitable means other than that disclosed, such as, for example, car-. bonizing the lower surface of the sheet 32 and of each strip.

80 The'inscription II to be later reproduced is on the sheet I! by the instrument 38 while the strips I, I and iii are in motion. The instrument is adapted to scan the open space within the frame I! by touching any point therein,

8 and in this sense the operation performed by the instrument is termed scan-scribing". The inscription is usually, but not necessarily, in the form of a signature. Due to the movement of the sheets, the transfer of the inscription is sep- 40 arated into components It on the respective strips. These components are unintelligible unless treated, assembled and used in the manner Presently to be described. As shown, they consist of undulations, or hills and valleys, similar to those forming the sound track of a phonograph record, and determined by the resultant of the direction or the-instrument II with the direction of each strip.

For reproducing the inscription, the strips I,

. so 0, and II areconverted into matrices IA, IA, and

IIA following the lines ll thereon. This may be done in numerous diflerent ways. consist of heavy material, they can be out along the lines ll; or the lines I! may be grooved after 55 inscription or during inscription by the addition of moving instruments attached by arms to the pen I! in such manner as to groove spacedapart strips on either surface. If they consist of material not suitable for cutting. the lines may be transferred photographically to film which is thus cut. Or, the strips may be given a protective coating at one side of the line and dissolved Y chemically at the other side of the line to leave an edge constituting a matrix conforming to the 55 line. The matrix lines are designated by the nu- "meral "A in Figure 3.

The matrix strips IA, 9A, and IIA are then placed in the same machine in which the inscription is made or in an identical machine. If the 7 same machine is used, the clamp frame I! is removed and replaced by a properly supported pen. For this purpose, a main arm 40 is pivotally mounted on a pin ll inserted in the bed I. The hub'" of the arm around the pivotal axis is sur- -7 rounded by a coil spring 48, one end of which If the strips bears against the arm and the other end is anchored in a finger 45 also mounted in the bed. To the free end of the arm Iii is pivotally at- 'tached a link ll by a pin 48. A spring 4'! surrounds the pin and has its ends bearing respecs tively against the members 40 and 45. The free end ofthe link ll carries a follower 48 adapted to lie at the common point of intersection of the several matrix edges "A.

In this connection it will be understood that the original profile lines 36 emanated, at any given instant, from a common point while being formed by the instrument 3:. Consequently, whenthe corresponding matrices are mounted in an identical? machine in the original angular relation to each other and run at the same speed, they also will intersect at one point at any given instant. This point, of intersection is followed by the follower 48 which therefore outlines the resultant of the several matrix components and hence outlines the original inscription. The transcription is, however, made by a suitable scribing instrument such as a fountain pen I! carried by the follower as shown in Figure 4. In one embodiment of the invention, the sheet for taking the transcription may be directly upon the bed'l and beneath the pen, follower and intersecting matrix strips.

In a preferred construction, however, anumber of sheets to be similarly inscribed are fed upwardly to the bed I. Accordingly, the bed has a removable section II directly beneath the pen 4! so that the pen may have access to the upper- -most sheet. The sheets are successively presented to the pen by any suitable mechanism such asa number of leaf springs II secured to the underside of the bed I and supporting a follower plate I! adapted to support the sheets. The lower surface of the plate carries a handle 53 by which the plate may be pulled down after the top 00 sheet has been inscribed, whereupon'this sheet may be withdrawn without smearing. On releasing of the handle, the next sheet is presented to the pen.

Guide strips Ilmaybemountedonthebed l 46 to m the edges of the traveling strips and thereby confine them to an accurate, straightline movement. The motor I is started, for either the scribing or the transcribing operation bya push button 6. It can be stopped at any times as in an emergency, by another button 51, although an automatic stop is preferred.

This stop consists of a metal clip I applied to an edge of one of the strips and engaging both surfaces, in conjunction with a pair of fixed 86 brushes I and II controlling the motor and between which the clip II is adapted to pass. The

brushes are wired to a solenoid 63 operating the throw-out switch II on the motor.

In forming the'original inscription I! by hand I) with the instrument a, the instrument will at operation, these members ride beneath a ring or projection II on the follower ll, as shown in Fig- 7 ure 4, and thereby lift the follower with the pen 4!! from the paper.

Further, in the transcribing operation, the superimposed, intersecting matrix strips are pressed against the bed I by a leaf spring it (Figure 4) which may be fastened to one of the pins 20.

Within the scope of the invention, the shifting point of intersection of the strips may be used in other ways to make the transcription. For example, the lines 36 may be originally scratched on a coated surface that becomes, or is treated to become, transparent along the lines. The strips are then passed in proper relation before a light, whereby there is projected a point of light outlining the inscription. This point, projected on apparatus of the type used in sound filmsycan operate mechanism for actuating the transcribing instrument. Inasmuch as the travel of the follower and transcribing pen is determined by the intersection of moving lines, only two such lines are necessary for determining the shifting point of intersection. Only two matrices might, however, occasionally form a sharp angle that binds and locks the follower. This contingency is avoided by the third matrix that constantly moves through the intersection of the first two matrices and thereby applies to the follower an independent 39 force constantly moving the follower out of the angle formed by the first two matrices.

The number of components formed from the original inscription may be increased beyond three, if desired, in which case the matrices would be similarly, increased and the difficulty of transcribing, in secret communication, would likewise be increased.

In the use of the invention, the inscription is originally made by the hand of the writer, and

40 the matrices are outlined. in the same manual operation. It is one of the important characteristics of the invention that the medium controlling transcription, namely the matrices, is produced with a minimum of manual intervention with the original manual inscription.

The inscription strips 8, 9 and 10 may be run through the machine at various relative speeds and angles with respect to each other, and the same relations must be preserved in the transcribing machine. Thus, these relations are essential elements, without the knowledge of which facsimile transcription is impossible. This condition is very desirable in the use of the invention as a means for transmitting messages in code by transmitting the intelligence of the respective component strips at different times by various agencies, in which case the transmitted matrices have no significance for facsimile transcription of messages unless their angular relation and relative speeds be known to the receiver, in order that thellatter may properly assemble the strips.

. After the matrices have served their purpose in transcribing a message or a signature, they may be destroyed or preserved in a safe. A code mes- 5 sage would of course be of no future value, and it is quite expedient to destroy matrices for signatures rather than keep them on file, since new strips can be easily made according to the invention by the means described herein. In the case 70 of tax receipts and the like, where future reference may be necessary, the matrices may of course be preserved.

Although the strips are herein shown as physically crossing each other, the matrices may be 76 prepared and transcribed without physically crossing each other, but placed at an angle to each other as previously described. In such case, the matrices would be inscribed by the use of multiple pens and transcribed by the use of extension arms from the respective matrices to the transcribing pen, or a group of transcribing pens, if desired, for simultaneously reproducing the original inscription on several surfaces.

The words inscribe" and inscription are here employed in the sense defined in the New Century Dictionary (copyright 1933-1934) and including further the delineation, by any means, of any writing, drawing, picture, character, symbol, design, and in fact, any matter that is subject to delineation for representationpn a surface.
