Title: Improvements in and relating to casting machines for curved stereoplates
IPC: B41D3/00
Filed: 1924-12-30
Abstract: 233,627. Winkler, C. Dec. 30, 1924. Stereotype, casting. In a stereotype-casting machine of the type in which the mould is adapted to be pressed against the melting-pot which is provided with a cock to control the flow of metal, the mould bed and the core are carried by sets of levers and are pressed by a counterweight acting on the bed against the pot. The bed 7 and core 8 are carried by pairs of levers 5, 6 respectively, which are attached to the ends of a shaft 4 mounted in the side walls 3 of the furnace. The bed 7 is connected by cables 9 to a counterweight 13 and is held in open position by a pedal 14. When released from the pedal, the bed is moved by the counterweight against the core 8 and the two parts are then pressed against the pot 1, the completion of this movement effecting the closing of the circuit of an electric motor 18. Depression of a hand-lever 20 against the action of a spring 22 effects the engagement of clutch-members 19, 23 connected to the motor, and through the medium of wormgearing 24, 25, connecting-rod 26 and lever 27 opens the cock 2 of the melting-pot. The lever 20 is held in depressed position by a pawl 28, which is adapted to be disengaged, to allow the lever to be retracted by the spring 22, by a tappet 29 rotating with the worm-wheel 25. To close the cook, the lever is again depressed, a tappet 30 serving to release it. The lever 27 is provided with a hook which is adapted to engage with a roller 31 on the bed 7 in order to lock the parts of the mould in position against the pot when the cock is opened, the closing of the cock effecting the release of the mould parts. The mould is opened by pressing down the handle 7<a>, relative movement between the bed and core being limited by a roller 32 on the bed travelling in a slotted guide 33 on one of the levers 6. The downward movement of the core is limited by stops on the side walls engaging the levers 6. The cast plate 34 hangs from the top edge of the core when the mould is opened.

Title: Improvements in or relating to phototypographical machines
IPC: B41B27/28
Filed: 1958-10-01
Abstract: 905,457. Photographic type - composing apparatus. MERGENTHALER LINOTYPE CO. Oct. 1, 1958 [Nov. 14, 1957 (2)], No. 31415/58. Class 98 (1). In a photographic type-composing machine in which, as described for example in Specification 801,481, the characters are projected from a continuously-driven carriage, the exposure being made at an instant determined by agreement of the position of the carriage as determined by counting impulses generated photo-electrically by a grating carried by the carriage, with a position registered in accordance with perforated tape signals, arrangements are made whereby either all the photo-electric impulses or only alternate ones are counted at will so that the same row of slits in the grating can be used for two types, one twice the point size of the other. It is also arranged that the alternate ones of slots constituting a single row are offset so that the odd and even slots affect different photo-cells and the circuits are such that an impulse is only passed on if it is preceded by one of the opposite kind. In this way spurious impulses due to vibration of the carriage when stopped at an intermediate point are eliminated. Construction of grid and reading arrangement.- The grid is held on a frame 19, Fig. 2, mounted for up and down movement to bring a particular row of slits into co-operation with the reading arrangement, in accordance with the point size of the type being printed. The slits constituting a row are arranged as shown in Fig. 5 at equal horizontal distances with the even slits displaced downwardly. The reader comprises two aircooled lamps 35, 50 (not shown), each with an optical system arranged to project the image of an adjustable slit via the odd and even slits of the grid on to the cathodes of photo-cells 33, 34, respectively. Circuit arrangements, Figs. 11, 12.-The pulses from the odd and even photo-cells are amplified and shaped in separate paths and control the respective states of a bi-stable multivibrator which repeats each operation to a circuit 102 which produces a corresponding number of impulses in a single channel. This arrangement ensures that if the carriage is stopped at an intermediate position and vibrates sufficiently to cause the transmission of one or more spurious impulses, such impulses are ineffective since they are necessarily due either to an odd or to an even slot and the circuit inherently fails to respond except to alternate odd and even pulses. Normally contacts 105 are closed and the impulses from 102 are counted directly; but in the case of a type of double the point size normally associated with the operative row of slits in the grid, contacts 105 are opened and contacts 107, 113 closed. In this case, each impulse changes over a bi-stable multi-vibrator 111 but only the impulses due to a change in a particular direction are passed on and the number of impulses, accordingly, is halved. Specifications 801,480, 823,005 and 905,456 also are referred to.
