Title: An improved method of and means for applying water or other ink-rejecting agent to planographic printing plates
IPC: B41F7/26
Filed: 1931-07-23
Abstract: 379,475. Lithographic printing. TRIST, A. R., 56, Victoria Street, London. July 23, 1931, No. 21098. Convention date, July 25, 1930. [Class 100 (ii).] In a lithographic printing-machine, an inkrejecting agent is applied to the printing plate by a rotary brush in light contact with the plate and moving at a higher surface speed than that of the plate. The Figure shows a brush for applying a mixture of mercury and water vapour to a plate having non-printing areas of mercury amalgam. The brush comprises a perforated tube 5 covered with a napped fabric 9 and provided with two concentric tubes 16, 17 of fine wire gauze between which is packed a mixture of chalk and finely divided mercury. Centrally of the brush is arranged a fixed tube 11 connected to a supply nozzle 13 for water under pressure and provided with a straight row of perforations 12. Surrounding the tube 11 is a tube 14 provided with a helical row of perforations and rotatable by a handle 16 to bring any one of its perforations into register with one of the perforations 12. The brush is mounted in bearings 7 and rotated at high speed by a pulley S, the nap of the fabric contacting with the printing surface so lightly as not to injure the inked image. The water passing through the tubes 16, 17 carries sufficient mercury with it to maintain the printing plate in proper condition. The brush also acts to prevent tarnishing of the amalgamated surface of the plate. For applying water only for ordinary lithography, the tubes 16, 17 are omitted, and the tubes 11, 14 may also be omitted, the water being applied to the brush in any suitable manner.

Abstract: 247,482. Liptak, M. Sept. 4, 1925. Walls of the type comprising an outer permanent wall and an inner replaceable wall connected by blocks or bricks that are seated in the outer wall and extend into the inner wall have these connecting blocks obliquely set in the walls. Adjacent rows of the connecting blocks may extend in opposite directions to form a dovetail anchorage between the two walls, these connecting blocks forming shelves upon which the brickwork belts of the inner wall are built. The permanent wall comprises horizontal belts 15 of common bricks between which are set horizontal rows of oblique L-shaped blocks 16 of fire-clay, leaving oblique recesses into which are inserted the fire-clay connecting blocks 18. The blocks 16 in alternate rows are shaped with an acute angle and the blocks 16 in the intermediate rows with an obtuse angle to give the dove-tail effect when the blocks 18 are fused under the heat to the firebrick 17 of the inner wall built upon them. Blocks 18 of firebrick extending only through the replaceable wall fill the spaces between the connecting blocks 18, and indentations 18a in the blocks 18 enable them to be easily removed when worn, after removal of the part of the brickwork belt 17 immediately above them. The blocks 16 may be formed with longer outer wings so that the blocks 18 may be placed in pairs in the recesses, and the outer wall may comprise three horizontal courses of brickwork instead of two, the blocks 16 then having wider outer wings. In the case of a central or partition wall of a furnace the permanent wall 20 shown in plan in Fig. 11 includes horizontal rows of oblique spaced blocks 21 leaving oblique recesses in which are inserted long connecting blocks 23 projecting on each side of the permanent wall, forming shelves upon which the replaceable firebricks 22 are built. Indentations 23a facilitate removal of the blocks 23, and the spaces between these blocks are filled by shorter blocks 24. In this form also the connecting blocks 23 may be set in pairs. As shown the connecting and filling blocks are in the form of oblique parallelograms to give a smooth wall, but square blocks may be used, producing an irregular surface.
