DEVICE FOR PRODUCING WRITING CHARACTERS.

Specification of Letters Patent.

Patented Apr. 2, 1.912.

Application filed September 12, 1910. Serial No. 581,667.

To all whom it may concern Be it known that I, Gnono BAIIR, a subject of the German Emperor, and resident of Franklinstrassc 99, Berlin-(harlotteir burg, Germany, have invented certain new and useful Imprcwements in Devices for Producing l/Vriting Characters, of which the following is a specification.

My invention relates to a device for producing writing characters by the use of a transparent plate or straight edge of celluloid, glass or the like provided with incisions for use in guiding a marker. The plate or straight: edge is so disposed as to move along a guide such as a T-square but in such a manner that the wet writing is not affected by the displacement of the plate or straight edge. As compared with previously proposed devices of this kind, the novel and essential feature of the invention consists in that the transparent plate or straight edge is provided with successively arranged incisions some of which form guides for whole letters while others form guides for only parts of letters, namely of parts which have the same form in various letters so that by suitably adjusting the plate or straight edge whole letters and parts thereof can be readily drawn. \Vith this arrangement of letters and parts thereof, a complete set of incisions for lettering and numbering can be provided within comparatively small space and in such a manner as to exclude all free hand tracing of separate portions of the writing in any letter or number.

The improved device insures ready manipulation as well as the producing of clean and correct writing characters. WVith similar apparatus heretofore in use an easy manipulation of same has not been possible for the reason that the various characters and signs have not been systematically arranged and that the apparatus is often too large and too complicated for the reason that each writing character and number was complete. Some of the known apparatus necessitate the completing of some of the letters by hand so that the finish of the writing is in many cases objectionable.

It is advantageous to provide in the plate or straight edge various holes between the characters or incisions at difierent distances from the ground line, their use being for the production of stops and lines, espe cially horizontal lines, by inserting the pen therein and suitably shifting the plate or straight edge.

For writing with the aid of the aforesaid plate or straight edge it is advantageous to use pens having a tubular nozzle in connection with a reservoir.

The accompanying drawing shows several arrangements by way of example:

Figure 1 shows a plan of a suitable device for writing capital letters, the plate or straight edge being mounted in a guide arranged on a T-square. Fig. 2 is a cross section on the line I-I of Fig. 1. Fig. 3 shows a face-view of a plate for use in writing small letters. Fig. 4 shows in plan and section various separate letters or numerals. Fig. 5 is a front view and Fig. 6 is a longitudinal section of the writing pen.

According to Fig. 11, the numeral 1 denotes a T-squarc and 2 denotes the holder or guide for the transparent plate or straight edge 3. The holder 2 is advantageously formed with a handle 4 and with a spring-clip 5 or the like for holding the plate or straight-edge. The plate or straight edge 3 has several complete writing characters such for example as the letter N marked 6, letter Z marked 7, letter U marked 8, letter O marked 9, the.

numeral 2 marked 10, and so forth. The

numerals

11, 12, 13, I l and so forth serve for tracing parts of letters and some of them may be used for completing letters by shifting the plate or straight edge. Holes 20 are provided at various distances from the ground line 91 so as to serve for making stops and also for making lines by leaving the pen in the hole and shifting the plate or straight edge. The same remarks apply to the plate or straight edge shown in Fig. 3 and various separate letters or numerals are shown in Fig. 4.

The parts 15 shown in Fig. 4 are provided with guide strips 16 adapted to be guided along a T-square or the like and they also denote the letters or numbers that can be produced by each part.

The pen for tracing the letters consists of the known shank 1.7 and of a reservoir 18 in which is fitted a small tube 19 which projects sufficiently far from the reservoir 18 so as to enable it to reach the writing surface when inserted in the incisions of the plate or straight edge. The pen shown in Figs. 5 and 6 illustrates an example only, and various other forms may be adopted.

The device is used in the following manner. The holder 2 or the guide 16 is placed against the edge of the T-square 1 and is then shifted according to the requirements of the parts of either the plate or straight edge 3 or the separate parts 15. To write the word Puzo for example, the incisions 22, 8, 7 and 9 are used, each producing a complete letter. For writing the word Berlin the procedure is as follows :The letter B is formed by tracing part thereof in the incision 22 and then moving the plate or straight edge 3 to the left until the incision 11 forms the lower curved portion of the letter B. Then the straight edge 3 is shifted so as to bring the letter E in the required position with respect to the letter B whereupon the pen passes through the incision 23. The letter L is produced by suitably shifting and using the incision 23, which latter may also serve for forming the letter I although for the same purpose the incisions 6, 23, 13 and others may be used. The last letter N is traced in full through the incision 6. Numbers can be produced in the same manner as letters. The plate shown in Fig. 3 and the separate parts shown in Fig. 4 are used in the same manner.

l/Vhat I claim as my invention and desire to secure by Letters Patent is A device for producing writing characters consisting of a transparent plate or straight edge having a ground line and formed with successively arranged incisions and with perforations arranged therein at diiferent distances from the ground line, a spring-holder for said plate or straight edge, and a handle on said spring-holder, the latter being adapted to be guided on a T-square, substantially as set forth. I

In testimony whereof I have hereunto signed my name this 1st day ofSeptember 1910, in the presence of two subscribing witnesses.
