AN 1906:64832 CAPLUS DN 0:64832 TI METHOD OF MANUFACTURING TRANSPARENT PATTERNS IN Baynes, John PA de Forest, Lockwood, USA SO U.S. CODEN: USXXAM DT Patent LA English INCL 156062000; 40-615; 156-251; 156-253; 430-5 CC 29 (Leather and Glue) PATENT NO. KIND DATE APPLICATION NO. DATE --------------- ---- -------- -------------------- -------- PI US 418674 A 18900107 US AB To to all whom it may concern: Be it known that I, JOHN BAYNES, a subject of the Queen of Great Britain, and a resident of West Chester, Westchester county, New York, have invented a new and useful Improvement in the Manufacture of Transparent Patterns, of which the following is a specification. In the manufacture of certain articles, or in the ornamentation of such articles-as, for instance, in the ornamentation of the backs of watch-cases, the surfaces of vases, salvers, and various useful and ornamental objects, it is now the practice to employ transparent patterns consisting of glass with the pattern painted thereon by hand, which pattern is used between the object to be ornamented and the source of light, the rays of light passing through the pattern and acting photographically or otherwise to produce or aid in producing the desired result. The method of making such patterns by painting the desired matter upon the glass sheet is expensive, and the patterns so produced, unless carefully made, will present ragged edges, and are liable to permit a partial passage of the light at the parts which should be absolutely opaque and impenetrable. In order to overcome these objections, I produce the patterns in a manner which I will now describe, reference being had to the accompanying drawings, in which-Figure 1 is a perspective view of a prepared plate illustrating my improvements. Fig. 2 is an edge view illustrating one manner of using the completed pattern-plate, and Fig. 3 is an edge view illustrating another manner of employing the pattern-plate.
