Title: Improvements relating to garment presses
IPC: D06F71/34
Filed: 1933-12-18
Abstract: 430,657. Ironing-presses. RICHARDSON, J. R. S., and WHITAKER, Ltd., R. G., Middle Mill, Portland Road, Kingston-on- Thames. Dec. 18, 1933, No. 35563. [Class 138 (ii)] A press of the kind in which vapour is withdrawn from the pressing surface by vacuum apparatus controlled by power-operated means in conjunction with the opening of the press is characterized in that the said means includes a trip device by which the vacuum control valve is closed after a predetermined opening movement of the press. In the form shown in Fig. 1 wherein the press is closed by fluid pressure admitted to a cylinder 2 containing a piston, the rod 5 of which acts on a treadle 6 connected to the usual press-operating linkage, upward movement of the treadle during the press opening phase opens the valve 10 in the pipe between the buck and the source of suction. This is effected by means of a lug 15 which, during the upward stroke of the treadle, engages a lever 13 and thereby opens the valve 10. As the treadle continues its upward movement the lug 15 trips past the lever 13 and the valve 10 is closed again by its spring. The lever 13 is normally held up against the valve stem 11 by a light spring 14. A valve 3 in the exhaust pipe from the press operating cylinder 2 is operated by the movement of the piston rod so that the cylinder 1 functions as a dash-pot for the treadle during the opening phase. In the form shown in Fig. 3 air is bled from the fluid pressure cylinder 2 through a reducing valve 21 to a cylinder 18 containing a piston having an enlargement 19 on the rod 17 thereof. The enlargement coacts with a lever 20 which actuates the vacuum valve 10. After opening the valve 10 the enlargement slips by the lever 20 and the valve is closed by its spring. In another form the initial opening movement may energize a solenoid to open the vacuum valve with an interposed time lag device.

Abstract: 854,211. Vehicles supported by gaseous cushions. HOVERCRAFT DEVELOPMENT Ltd. Dec. 11, 1956 [Dec. 12, 1955], No. 35656/55. Class 4. A vehicle which comprises means for causing a fluid to issue from the lower part of the vehicle in such a way as to result in the formation and maintenance of at least one curtain of moving fluid which travels across the gap that in operation exists between the surface over which the vehicle is to hover or travel and the structure of the vehicle and, together with the said structure and surface, encloses a space into which the said fluid, or a gas other than the said fluid, flows so as to result in the formation of a pressurised cushion or cushions by which the vehicle is wholly or partly supported, the pressure of the cushion causing, and in its turn being contained due to, a change of direction of the moving fluid which results in a curvature of the curtain, and in which the means for forming the curtain are such that in cruising conditions the thrust due to the stream of fluid finally leaving the vehicle is substantially less than the weight of the vehicle when loaded. The fluid forming the curtain may be liquid, such as water or gaseous and in one example an air jet is projected through a substantially annular orifice 8, Fig. 3, on the vehicle undersurface, the thrust being obtained from a double propeller 3 driven by a motor 4, and located in an opening 2 in the vehicle and forcing air through a chamber 6 and tunnel 7 to the orifice 8. The pressure of air trapped under the vehicle surface causes the jet curtain to move in a substantially arcuate bell-mouthed path. Slots 15, connected to chamber 6 to provide air jets within the curtain, may be provided to divide the undersurface into separate compartments to maintain the vehicle in a stable attitude. Forward motion for the vehicle may be obtained by deflecting the annular jet backwards by vanes 9 in the orifice 8 or by separate engines arranged specifically for propelling. The vehicle may be steered by a tail plane 14 or by flaps 16, Fig. 6, operated by hydraulic motors 19 to restrict portions of the annular orifice 8. The system may be used in place of a conventional undercarriage for take-off or landing of aircraft on land or water.
