Title: Improvements in or relating to sheet-feeding mechanism of rotary printing machines
IPC: B41F21/05
Filed: 1927-02-16
Abstract: 287,688. Linotype & Machinery, Ltd., and Dowson, R. Feb. 16, 1927. Sheet carriers and register. ing devices; gripper mechanism.-Sheet-feeding mech anism for rotary printing- machines of the kind in which grippers on oscillating arms take sheets from front stops on a feed board and transfer them to grippers on the impression cylinder is constructed with improved means to allow a quick return of the oscillating grippers after the sheet has been transferred, the means consisting of devices operative independently of the oscillating members to raise the grippers out of the path of the sheet, and subsequently to lower the grippers as they approach the front stops. The gripper and lay mechanisms are carried by a. frame 9 which can be conveniently applied to or removed from a printing unit. The grippers 5 are mounted on a shaft 6 carried by arms 7 on a shaft 8, which is oscillated from a cam 11 by a lever 12, link 13, and arm 14. The grippers are closed by springs 16 acting on arms 15 on shaft 6, and are opened to take the sheets from front stops 4 by means of a movable cam 20, and to deliver the sheets to grippers on the impression cyclinder by a cam 19 operated by a spring 39 and cam 38 on an offset cylinder 1. A stop 24 may be operated from the trip mechanism of the press to prevent the closing of the grippers at the sheet-receiving position when the printing-mechanism is tripped. The cam 20 is normally oscillated from a cam 21 on the cylinder 1, but, when the stop 24 is operated, the cam is prevented from allowing the grippers to close at the sheet-receiving position. The shaft 8 is mounted in eccentric bearings 30, and after the sheet is taken bv the impression cylinder 2 these bearings are rocked by a cam 35, levers 36, 33, and links 32, and arms 31. to raise the shaft 8 and allow the grippers 5 to return past the cylinder 2 without touching it. The shaft 34 of the levers 33 returns under spring action, and its final position is controlled by an adjustable stop 40, which thus controls the angular position of the eccentric bushes 30. The front stops 4 are mounted on a shoot 26 rocked by a cam 27 on the impression cylinder 2 through a link 28 and lever 29.

Title: Improvements relating to regulating devices for vehicle brakes
IPC: B60T8/74
Filed: 1927-02-16
Abstract: 266,356. Hallot, P., (Assignee of Mecanique Lyonnaise). Feb. 17, 1926, [Convention date]. Fluid-pressure.-Vehicles provided with fluid-pressure brakes are fitted with an inertia governor device adapted to relieve the braking pressure should the wheels tend to lock. As applied to a motor vehicle with vacuum brakes operated by the engine suction, the device comprises a quick-pitch screw 4 driven from a part connected to the rear wheels. A nut 5 engaged with the screw 4 carries a flywheel 6. Movement of the nut with respect to the screw is limited by a pin 7 and notch 8. The valve device controlled by the governor comprises a casing 20 having a connection 21 to the brake cylinder and a connection 25 to the main pedal actuated control valve. When the main control valve is operated to apply the brake, air from the brake cylinder is withdrawn past the valve 16. If the vacuum is excessive so that the wheels tend to lock, the tendency of the screw 4 to stop causes the nut 5 and flywheel 6 to travel to the right so that a pin 9 on the nut opens a valve 10 against the action of a spring 12 to admit air to the brake cylinder and, acting on the valve 16 through a spring 19, seats this valve to cut off the brake cylinder from the engine suction. When the vacuum has been sufficiently reduced the nut returns to its original position and the value 10 re-closes, but the valve 16 remains closed under the influence of the pressure difference acting on its two faces. To prevent jamming of the front wheels, the brake transmission system may be such that the effort applied to the front brakes is nine-tenth of that applied to the rear brakes. A clutch may be arranged between the screw 4 and the driving gear therefor.
