Abstract: 354,586. Ironing-presses. BRITISHAMERICAN LAUNDRY MACHINERY CO., Ltd., Underhill Street, London.- (American Laundry Machinery Co. ; Norwood Station, Cincinnati, Ohio, U.S.A.) Sept. 9, 1930, No. 26958. [Class 138 (ii).] A rotary turret multiple ironing-press comprises a number of stationary press heads 16, Fig. 1, and a larger number of press beds 9 supported on arms 7a which are pivoted to the rotary turret structure 5. The stationary heads are so spaced around the turret that a space is left between two of the heads sufficient to accommodate two beds, an operator removing the finished article from one bed and another operator loading the other bed. The remaining heads are so spaced that one bed may be accommodated between them, an operator at each space rearranging the article on the bed. The turret is intermittently rotated from an electric motor 40 through worm and bevel gear 39 .. 36, Fig. 2, the arms 7a being provided with depending rollers 11 which run around a track 12. The beds that register with heads are raised into pressing engagement therewith, when the turret is stationary, by steam-actuated p.ston and plunger mechanisms 19. A pilot motor 50, Fig. 5, which runs continuously when a main switch 75 is closed controls the running of the main motor 40 and the fluid pressure inlet and exhaust valves which work in unison and are carried by stems 28, 30 respectively. When a conductor strip 56 on a continuously driven drum 54 bridges contacts 65, 66 a coil 68 is energized to cause a conductor 70 to bridge contacts 73, 74 to complete the main motor circuit which includes a solenoid 48, energization of which releases a band brake acting on th( motor shaft. The turret is consequently rotated and one of the conductor segments 58 of a commutator carried thereby bridges stationary contacts 60, 61 to complete the maintaining circuit for the main motor circuit which would otherwise be broken when the segment 56 ceased to bridge the contacts 65, 66. The maintaining circuit of the main motor circuit is broken when the commutator 57 has rotated sufficiently to bring one of the gaps 59 thereon into registration wit the contacts 60, 61, the coil 68 then becoming de-energized and causing the conductor 70 to open the main motor circuit at the points 73, 74. The stopping of the main motor, which is accompanied by the application of the band bralie, is arranged, to occur when the appropriate press beds are registering with the heads. The conductor 70, in breaking the main motor circuit at 73, 74, bridges other contacts 71, 72. These contacts are in series with a solenoid 33 which when energized opens the steam inlet valves to the cylinders of the piston and plungers 19 and closes the exhaust valves thereof, and with stationary contacts 63, 64 which, on continued rotation of the drum 54, are bridged by a conductor 55. When this circuit is completed the piston and plunger mechanisms are actuated to raise the beds into contact with the press heads and to maintain them until the conductor 55 moves off the contacts 63, 64 whereupon the solenoid 33 is de-energized, the steam inlet valve is closed and the exhaust valve opened by a spring around the valve stem 30. The main motor and the turret structure remain stationary until the conductor 56 again bridges the contacts 65, 66.
