THEODORE I. I-IEINEMANN, OF CONNERSVILLE, INDIANA, ASSIGNOR TO THE SIG-N COMPANY, OF 00 TRIPLE-SIGN MANUFACTTIRE.

To all whom it may concern:

Be it known that I, THEODORE P. I'IEINE- MANN, a citizen of the United States, residing at Connersville, Fayette county, Indiana, have invented certain new and useful Improvements in Triple-Sign Manufacture, of which the following is a specification.

This invention pertains to the manufacture of triple signs, being that class of signs which show one reading when viewed directly from the front, and another reading when viewed diagonally from the left and still another reading when viewed diagonally from the right, and it relates particularly to the manufacture of that type of triple signs in which the forwardly projecting vertical slats are formed by being out from a sheet previously prepared by having delineated upon the front of the sheet the matter which is to be read when the completed sign is viewed diagonally from one direction, and having delineated upon the back of the sheet the matter which is to be read when viewed diagonally in the other direction.

The improved manufacture will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is a perspective view of a triple sign as viewed diagonally from the left: Fig. 2 a perspective view of the same sign when viewed diagonally from the right: Fig. 3 a front elevation of the rear member of the sign: Fig. i an elevation of the preliminary pattern employed in arranging for the delineation of the sign-matter upon the rear surface of the front plate of the sign: and Fig. 5 a front elevation of the final pat tern for the sign work upon the rear surface of the front plate of the sign.

In illustrating my invention I have chosen, as a simple exemplification, a sign of three letters or symbols only, the letter D when the sign is viewed diagonally from the left, the letter E when it is viewed squarely from the front, and the letter A when it is viewed diagonally from the right.

In the drawing :-1., indicates the rear member of the sign, being the tablet which is to be viewed through the open work of the front member: 2, sign -matter delineated on the front face thereof in the form in which it is to appear when the triple sign is viewed from the front: 8, the front plate,

overlying the rear member: t, a horizontal series of vertical slats disposed parallel with each other and projecting forwardly from the front plate, these slats being formed by suitably cutting them from the front plate: 5, signmatter delineated upon the left hand faces of the projecting slats 4, or the face corresponding with the front of the front plate before the slats are bent forwardly: 6, sign-matter upon the opposite faces of the projecting slats, corresponding with the rear face of the front plate before the slats are bent forwardly: 7, a preliminary pattern sheet corresponding substantially in size with the front plate: 8, vertical divisions laid off upon this preliminary pattern plate, the divisions corresponding in width with the divisions represented by the slats of the front plate: 9, sign-matter delineated upon the preliminary pattern and corresponding with the signmatter which is to appear upon the triple sign when the latter is viewed in such diagonal direction as to comprehend those faces of the slats which originally were at the rear of the front plate: 10, numbers indicating the relative position of the divisions 8 in the preliminary pattern, or at least such of those divisions as are involved in the sign-matter to be dealt with: 11, the final pattern for the sign-matter which is to be upon the back of the front plate before the slats are bent forward: 12, the sign-matter as it appears upon the final pattern in order to bring about the sign-matter as indicated in Figs. 2 and 4: and 13, the division numbers 10 after transposition of the pattern divisions to which they pertain.

Assuming the three sign-matters found in the example, namely, the letters D, E and A, the letter E will be delineated upon the front face of the rear member, without modification, as seen in Fig. 3. \Vhile the front plate is still in flat condition the letter D will be delineated upon its front face, and without modification; that is to say, just as it is to appear when the triple sign is viewed diagonally from such direction as will comprehend those sides of the slats which originally formed the front face of the front plate. In short, the delineation of these two sign matters has called for no special patterns, their production involving the simple delineation of the two sign-matters as they are to appear upon the sign. But the de lineation of the sign-matter for the opposite faces of the slats, the faces originally corresponding with the rear surface of the front plate, is an entirely different matter and is arranged for as follows i The temporary pattern 7 is to have delineated upon it the sign-matter derived from the rear surface of the front plate and this sign-matter is to be delineated upon the temporary pattern in just the form in which it is to appear in the completed triple sign when the sign is so viewed as to expose matter which was originally on the rear surface of the front plate. This temporary pattern is now to be laid off in divisions corresponding with the spacing of the slats, and then the temporary pattern is to be cut up into these separate divisions, the divisions being first serially numbered as in Fig. 4. The temporary pattern may be made of a complete sheet out up into divisions after the sign-matter has been delineated upon it, or the temporary pattern may be formed by laying together side by side the several divisions previously formed, and then properly delineating the sign matter upon the assembled divisions. The temporary pattern with its separable divisions having been completed, those divisions involved in the sign-matter are now transposed as indicated in Fig. 5. This completes the final as distinguished from the temporary pattern. The abnormal sign-matter appearing upon this final pattern is now to be delineated upon the back of the front plate, while the front plate is in fiat condition, the front surface of the front plate bearing normal sign- I matter. The transferring of the abnormal sign-matter from the final pattern to the l back of the fiat front plate may be done in l any desired suitable manner, as by painting, lithographing or otherwise.

It 1s to be understood that triple signs of the general class referred to may be formed of paper, metal, or other material, metal being the preferable material when the front member of the sign is formed by cutting loose and bending forward the slats without actually disconnecting the slats from each other, and the term plate or sheet employed herein is to be considered regardless of the material of which the plate or sheet may be formed.

I claim 1. The improved method of triple sign manufacture consisting in delineating normal sign matter on a flat pattern, dividing that pattern into a series of strips in correspondence with the slat spacing of the sign to be produced, reversibly transposing the strips bearing said sign matter, thereby producing a flat pattern bearing abnormal sign matter, and copying said abnormal sign matter on a plate to form part of the sign, as substantially set forth.

2. The improved method of triple sign manufacture consisting in delineating normal sign matter on a flat pattern, dividing that pattern into a series of strips in correspondence with the slat spacing of the sign to be produced, reversely transposing the strips bearing said sign matter thereby producing abnormal sign matter, copying said abnormal sign matter on the back of a front plate, and delineating normal sign matter on the front of said front plate, all substantially as set forth.
