Abstract: 211,458. Fallot, A. Feb. 14, 1923, [Convention date]. Rotary offset machines.-A rotary offset machine is constructed to allow of ready accessibility of the parts of the machine, to take up small floor space, and to allow of deliver without undue bending of the sheets. The machine is of the kind in which the plane containing the axes of the plate cylinder l and offset b is inclined at an obtuse angles to the plane containing the axes of the cylinder b and an impression cylinder a. According to the invention, the sheets are fed to the grippers g of cylinder a by means of auxiliary grippers f which take the sheets from the feed board e, and the sheets are delivered by grippers on chains c arranged to take off the sheets at approximately or slightly above the height of the centre of the impression cylinder a. This arrangement permits the damping-apparatus m to be arranged low down on the plate cylinder l and with a space between the damping-apparatus m and inking-apparatus n, and also between this and the offset cylinder b. The operator can thus inspect the working of the damping and inking apparatus readily, and apply a wet sponge to the plate if the damping-apparatus is not working correctly, or adjust the ink distribution if required, and watch the condition of the blanket on cylinder b.

IPC: G11B3/38
Filed: 1959-01-22
Abstract: 843,592. Automatic gramophones. STEIDINGER, O., and STEIDINGER, S., [trading as STEIDINGER KOMM.-GES. GEB.]. Jan. 22, 1959, No. 2346/59. Class 40 (2). In a pick-up arm, a device for detecting the record diameter comprises retractable supporting members projecting below the stylus at different levels and adapted to be locked in the extended position, and a control mechanism driven by the driving motor operated by the starting button or the run-out groove of the record to unlock and retract the said supporting members. The supporting members comprise rollers 39 and 40, the roller 40 being lower than the roller 39 and set such that an outward movement of the pick-up arm is caused when in contact with the record, while the roller 39 is set to produce an inward movement when roller 40 drops over the edge of the record. At such a stage in an automatic cycle, a lifting rod 9 in contact with a leaf spring 13 lifts the pick-up arm about a pivot 6 until stopped by the abutment of stops 29 and 30. At this point the spring 13 flexes and lifts a pin 20 from engagement with a spring-loaded slide 18 registering with the rod 9 and permits a link 14 to allow the withdrawal of an oblique cam 32 under the influence of a spring 42 so that the bracket 38 carrying the rollers is withdrawn. The lowering of rod 9 then permits the stylus to engage the record. At the end of the playing of a record the initiation of an automatic cycle causes the rod 9 to be slightly raised so that the conical part thereon relatches the pin 20 and cam 32 into the position in which the rollers 39, 40 are again extended for a record diameter detecting operation, and at the same time reduces the tension of a weight reducing coiled spring 25.
