RICHARD C. MARTENS, OF LONDON, ENGLAND. I
APPARATUS FOR CODING MESSAGES.
Specification of Letters Patent.
Patented July a, 1916,
Application filed April 19, 1916. Serial No. 92,185.
T0 all whom t 'may concern Be it known that I, RICHARD C. MARTENS, a subject of the Emperor of Russia, and a resident of the city of London, Kingdom of England, have invented a new and useful Improvement in Apparatus for Coding Messages, of which the following is a speci fication.
This invention relates to the art of transmitting intelligence by means of code messages.
In the business of importing and eXporting houses there is constant necessity for sending messages relating to articles illustrated in the catalogues of manufacturers and dealers, and, in the case of a concern doing an active business, the aggregate of tolls becomes very heavy. This expense could be largely reduced if there were some short way of designating particular cuts upon the printed page. Thus, with proper coding, it may be possible to specify the particular catalogue and page, including the manufacturers name and the class of goods, all within one word, but particularizing one cut upon a page may require two or three words more.
By the present invention I am enabled to designate any cut by a single symbol, which may constitute a word by itself or be incorporated with other matter in a longer code word. upon the page of the catalogue containing the particular cut in question a sheet of transparent material ruled with parallel vertical and horizontal lines, suitably numbered in the margins. The top and lefthand boundaries of the ruled area of this sheet are caused to register with the upper and left-hand boundaries of the printed portion of the page; the numbers of the lines which intersect over the given cut, preferably substantially at its center, are
This is accomplished by placing then noted; a symbol for these numbers is found in the code book, and such symbol incorporated in the message. The recipient, being provided with a corresponding ruled sheet, merely has to apply the same to the page of his copy of the catalogue in order to ascertain the cut referred to.
The invention is illustrated in the accompanying drawings, wherein- Figure l represent-s a catalogue, lying open, with a fragment of the transparent ruled sheet superposed in proper registry upon one of its pages; and Fig. 2 represents a simple form of one of the ruled sheets,
In the supposed catalogue of the drawing it will be perceived that the lower left-hand cut, representing a nut, may be designated by the intersection 20-100, which by aid of a code may be expressed Very briefly. The boundaries of the ruled area of the transparent sheet are registered with the printing matteion the page of the catalogue rather than with the edges of the page, in order to avoid the possibility of error which would otherwise arise from variations in the margins of different Copies of the same catalogue.
Vhat I claim as new is:
Apparatus for use in sending messages by code comprising a transparent sheet having vertical and horizontal lines and indicia designating the same adapted to be superposed on the pages of a catalogue or the like to assist in identifying a particular cut on the page.
In witness whereof, I have hereunto set my hand this 18th day of April, 1916.
