Title: Improvements in or relating to reproducing the surface markings of wood and other material
IPC: B41M3/06
Filed: 1931-04-15
Abstract: 374,206. Printing-surfaces. OXFORD VARNISH CORPORATION, Empire Building, Detroit, Michigan, U.S.A.-(Assignees of Casto, L. V.; 4084, West Philadelphia Avenue, Detroit, Michigan, U.S.A.) April 15, 1931, No. 11213. Convention date, April 16, 1930. [Class 100 (ii).] The appearance of natural objects such as high-grade wood, marble, and the like is reproduced on a base such as metal, wall board, inexpensive woods, and the like, by the employment of two printing-surfaces bearing the design respectively in sharp and weak contrast as in Specification 374,205, photographs of the original material showing the design in sharp and weak contrast being used in the preparation of the printing-surfaces. The impressions from the printing-surfaces are applied without regard to registration to a base treated to represent the ground colour of the material to be reproduced, a darker colour being used with the sharp-contrast surface than with the weak-contrast surface. The photographs are used to prepare resists, for example as described in Specification 169,515, [Class 100 (ii), Printing processes &c.], through which the printing-surfaces are etched. The weak-contrast photograph is prepared on a soft emulsion film such as a portrait film supported on a base such as celluloid, glass, paper, or the like, and the other photograph is prepared on a process film. Preferably a shallow etching is used for the weak-contrast printing- surface and a deep etching for the sharpcontrast surface. The degree of contrast may be controlled by the timing and development of the photograph, and the etching may also be controlled as in Specification 374,205. The weak-contrast printing-surface may be used with any one of a number of sharp-contrast surfaces each arranged to print a different grain design.

The sacks are ejected through the opening in turn by an inclined, plate 14, or merely fall by gravity, passing between the cross-bars on the return run on to a shoot, not shown.. To prevent jamming the sacks are assisted in passing between the cross-bars by a roller 6 and a supporting flap 9 which normally extends across the path of the cross-bars and rests on a stop 11. Flap 9 is hinged at 10 and coupled by levers 12b, 12c to a member 12a hinged to the guides for the return run of the chains, such that upon engagement of the member 12a by the returning cross-bar 13 the flap 9 is hinged upwardly to the chain line position out of the way of the cross-bar. The flap returns to normal position by gravity or spring means. A door may also be provided for closing the opening in the trough when a sack is not being discharged.
