Abstract: 346,258. Pressing-machines. PROSPERITY CO., Inc., Beattie Street, Syracuse, New York, U.S.A.-(Assignees of Davis, E. ; 324, Roosevelt Avenue, Syracuse, New York, U.S.A.) Oct. 4, 1929, No. 30180. Convention date, Jan. 26. [Class 138 (ii).] In a press or other machine having an opening and closing movement and wherein the closing movement is controlled by manually closing two exhaust valves associated with a pressure fluid supply pipe and which is opened by actuation of a third manual control, means are provided to reset positively the press-closing controls on actuation of the press-opening control. As shown a main control 30 actuates the inlet valve 29 in the fluid supply pipe 28, and the two press-closing manual controls comprise exhaust valves 20, 21 which are closed by depressing buttons 33, 34 respectively. The buttons must be maintained depressed until after the piston 2 operating the press-closing link and lever system has passed a port 53 in the cylinder 1, whereupon the exhaust valves are automatically held closed by the fluid pressure acting through diaphragm chambers 43, 44. The press is opened by depressing a lever 54 of which an extension 56 engages the intermediate valve-operating lever 37 to swing the latter counterclockwise thereby permitting the exhaust valve 20 to open and exhaust the cylinder and diaphragm chambers. The upper end of the lever 37 engages the lever 35 on which the button 33 directly acts and rotates this lever so that the button is raised and thereby positively reset. The button 34 is also raised by the rotation of a rock-shaft 57 carrying arms 58, 60 engaging respectively the levers 54, 36. The press may be initially closed, without the application of heavy pressure by a separate piston and cylinder member 60a, to which pressure fluid is admitted from a pipe 67 through a pedal controlled valve 65. As shown, an inlet valve 210 may be provided on the stem of the exhaust valve 21 for actuation by the button 34, the valve 210 being in series with the main inlet valve 29. In a modification the inlet valve 29 and the initial closing cylinder 60a and controls therefor are omitted.

Title: Improvements in or relating to gramophones
IPC: G03B31/00
Filed: 1928-10-30
Abstract: 300,269. Robimarga, L. Nov. 10, 1927, [Convention date]. Multiple machines ; combined working of gramophones with kinematographs. - Relates to multiple-turntable gramophones, and consists in mechanism whereby several turntables, loose on continuously driven shafts, are brought into operation separately and in continuous succession, by being clutched to or declutched from the shafts. The control is effected by an apertured moving band coacting with electric contacts. The invention, which provides for continuity of sound-reproduction by automatic changing over from one record to another, is applicable to gramophones working in synchronism with kinematographs. In the apparatus shown, a motor A drives a turntable spindle 1<1>, this being geared to a similar spindle 1<11> through wheels 4 - - 8. Each turntable 2', 2<11> is loosely mounted on its spindle, and each carries a spring- controlled pawl 10<1> or 10<11> adapted to engage with a toothed disc 3' or 3" fixed on the said spindle. When the parts 3, 10 associated with either turntable are thus engaged, that turntable is driven. A centrally-pivoted lever 12 is so mounted that lugs 14<1>, 14" carried thereby can move into the path of the ends of the pawls 10<1>, 10<11>, respectively, so as to disengage either of these pawls from its toothed disc 3 white at tha same time the corresponding parts associated with the other turntable remain in engagement. By this means, whenever the inclination of the lever 12 is reversed, one turntable is started and the other one is stopped. Movement of the lever 12 is ejected by means of electromagnets 26<1>, 26", which are energized in turn, as required, on the completion of one or other of two circuits controlled by contact members 22<1>, 22<11>. These contacts bear on an insulating band 19, which is driven by a wheel 16 in synchronism with the turntable spindles. The band is provided at predetermined positions with slots 24<1>, 24<11> which control the starting and stopping of the turntables by allowing one or other of the contacts to complete the circuit through the corresponding electromagnet. Instead of using a special controlling band, the necessary slots may be provided on a kinematograph film. An electromagnetic synchronism-controlling device may be operated by means of a, contact-making arm 27 on one of the gear wheels 7.
