Printing surfaces.-A printing plate cylinder 20 includes a shaft 60 rotatable from plate locking to plate unlocking position, plate tensioning hooks 65 engageable with the plate near one end thereof and rotatably journalled on the shaft 60, and springs 74 for individually rotating the hooks on the shaft, the hooks being retracted by rotation of the shaft. The shaft 60 has splined thereto collars 75 provided with slots 78 adapted to receive one end of the torsion springs 74, the other ends of which are formed with an axially extending end 84 which engages in a notch 85 formed directly to the rear of the hook 68. To limit movement of the hook members 65 a slot 81 is provided therein through which a bar 80 passes, the ends of the bar 80 being fitted into the slots 78. A plate lifting ear 70 is also provided on the hook members 65. The shaft 60 is carried by bearings 64 seated in the cylinder body and may be rotated from plate locking to plate unlocking position by linkage 90, 91-94 and worm gear 96. The other edges of the plates 22 are held in position by circumferentially movable hooks 26 mounted on bars 28 which fit into T-shaped slots in the cylinder and are adjusted by rods 41, 42-44, each of which is provided with an upstanding prong 46 which engages a wedge member 39. Each bar 28 is provided with two cam members 38 which co-operate with wedges 39 so that by moving the rods 41, 42-44, each of the bars 28 may be individually positioned and if necessary may be slightly skewed. Rods 41, 42-44 are formed at their ends with a rack portion which co-operates with a pinion 54 on a wrench 52, the wrench 52 being provided with four annular grooves co-operating with a pin 50 so that it may be positioned to move any one of the rods 41, 42-44. In a further embodiment (Figs. 12 and 13) compression springs 175 provided in the shaft 160 are compressed by screw plugs 177, and bear against abutments 180 slidable in the shaft. The abutments carry a square pin 182 provided with enlarged rotatable roller ends 184, slid able in slots 186 in the walls of the shaft 160 and bearing against helical slots 188 formed in the plate hook sleeves 165, thus causing the plate hook to tend to rotate relatively to the shaft.

Abstract: 296,105. Schobbens, V. Aug. 26, 1927, [Convention date]. Addition to 276,681. Spray carburettors.-The carburettor described in the parent Specification which uses gaseous fuel, is modified for use with either liquid or gaseous fuel. Liquid fuel is supplied from a, float chamber 29, Fig. 2, through a conduit 28 to a main nozzle 27, Fig. 1, and through a conduit 30 controlled by a three-way cock 12 to a slow-running nozzle 6. The nozzles 2'7, 6 open into a mixing-chamber 3 provided with an air inlet 38 and a mixture outlet 4. Gaseous fuel under pressure is admitted to an expansion chamber 45 through an orifice 48 controlled by a manuallyoperated valve 49 and passes through a conduit 46 to a main nozzle 26 surrounding the liquid fuel nozzle 27, and through a conduit 47 and the cock 12 to the slow-running nozzle 6. The outlets of the nozzles 26, 27 are controlled by a spring- loaded valve 31 provided with a head 34 engaged by a cam 35 connected to the spindle 5<1> of the throttle valve 5. The slow-running nozzle 6 is controlled by a suction-actuated sleeve 18 provided with outlet apertures 20 and loaded by a spring 24 acting through a rod 23. Air is admitted to the interior of the sleeve 18 through ports 15 controlled by a ported sleeve 16. The supply of gas to the main nozzle 26 is controlled by a valve 62 coacting with the conduit 46, the valve being spring-loaded and provided with a pin 61 engaged by one arm 60 of a bell-crank lever, the other arm 58 of which engages a diaphragm 51. A rod 53 bears on the diaphragm 51 and is engaged by a lever 56 against which bears a pin 57 eccentrically-mounted in the end of a spindle 42, the spindle 42 being provided with an arm 41 which is connected by a cable 43 to a suctionactuated flap 39 controlling the main air inlet 38. When suction ceases in the carburettor, the closing of the valve 62 by the spring 64 effects the closing of the air valve 39. When liquid fuel is used, the connection between the main fuel tank and the float chamber 29 is opened, the valve 49 is closed, and the cock 12 is positioned to connect the conduit 38 to the slow-running nozzle 6; when gaseous fuel is used, the float chamber is emptied, the valve 49 is opened, and the cock 12 positioned to connect the conduit 47 to the slow-running nozzle.
