Abstract: 869,998. Proof-printing apparatus. McFARLAND, J. A. Aug. 25, 1959, No. 28984/59. Classes 100(2) and 100(3) A manually portable device for taking proof copy from type &c. 27 in a made-up chase or forme 24 having spaced parallel side members 22, comprises a carriage adapted to be reciprocated by hand over the forme 27 and including side members 2 which engage the members 22, and a fixed shaft 6 on which is mounted a frame 28 carrying an inking roller 32 and an impression roller 34, either of which can be brought into position to engage the forme. Each side member has three rollers, such as 8, and a fixed abutment 14 which engage side extensions on the forme members 22 to guide the carriage. The frame 28 comprises slotted ends 30 carrying bearings for the shafts of the rollers 32, 34, each bearing being spring-urged away from the axis of the shaft 6, and the ends 30 are mounted rotatably, on the shaft 6 by central bearings provided with spring-urged locking pins adapted to engage in recesses in the shaft 6 whereby the frame can be releasably locked in either of three positions, i.e. two in which one or the other roller engages the forme, and a neutral position. In operation, when the type &c. is set-up, the carriage is engaged over the members 22 of the forme, and is reciprocated over the forme, first with the inking roller 32, and then with the impression roller 34, in contact with the type, a sheet of paper being placed over the type between these reciprocations. In the case where the ends 22 of the forme 24 are not recessed as at 26 to provide extensions beneath whichthe rollers 8 engage, the carriage is modified by arranging one side member 2 to have screwthread engagement with the shaft 6, and sliding engagement with the cross-bar 4. In this modification, the carriage rollers 8 &c. engage the plain end faces of the members 22 by friction when the said side member 2 is urged inwardly by the screw-thread means. Inking-apparatus:-The roller 32 is inked between each proof-printing operation by an ink reservoir roller 90 supported on spring-urged pivoted arms supported on the two members 30. The roller 90 comprises two tubes rotatable with respect to each other by knurled knobs on their ends to bring apertures therein into coincidence, thus permitting ink to flow on to the roller 32, and a hand-crank device fitted on one member 2 is then rotated to distribute the ink over the roller 32.

Abstract: 280,218. Lehinant, A. Nov. 3, 1926, [Convention date]. Sluice gates.-A weir of the horizontally hinged type with the hinge at the bed of the channel is automatically controlled so as to maintain a predetermined water level by means of a counterweight, rolling weights, and float members actuated by the water on the downstream side of the weir. The weir A, Figs. 1 and 3, is supported by means of a counterweight D extending across the channel and hung from the ends of levers C at each side of the channel. The levers. C are pivoted centrally and are also supported on shafts E which are mounted on floating members F located in chambers H formed in the banks at each side of the channel and connected by a conduit J. Gates M, G, above and below the weir respectively, control the level of the water in the chambers H. The upstream ends of the levers C are connected to the upper edge of the weir A by links B. In the position shown, the weir is in equilibrium, the pressure of the upstream water and the weight of the weir being balanced by the counterweights D. If the upstream level rises the weir descends and the downstream level rises. The floats F are arranged so that they come into operation when the water level 2, shown in Fig. 1 in broken line, below the weir is the same as that above. At this level, the weir is kept in equilibrium in the position 2, shown in broken lines. On further rise of level, the opening of the weir is assisted by weights K rolling on guides L on the levers C. The hinge of the weir is kept watertight by packing com- -prising two plates 0, P, Fig. 4, the plate 0 being pivoted to the weir A so as to form a watertight joint, while the plate P is secured to a plate Q on the bed of the channel. The plate 0 is located below the plate P and its lower edge slides on the plate Q as the weir moves.
