Title: Improvements relating to devices for keeping trousers and the like in creases
IPC: A47G25/72
Filed: 1944-11-14
Abstract: 583,660. Trouser stretchers. FLETCHER, F. G. Nov. 14, 1944, Nos. 22466/44 and 4626/45. [Class 141] A trousers press comprises a flexible sheet having means on one side for gripping the trousers which are inserted whilst the sheet is flexed concavely, the trousers being stretched either by the natural tendency of the sheet to return to its flat state or by its being subsequently held in a convexly flexed position. As shown, a laterally projecting cross-piece 2 is fixed to each end of the flexible sheet 1 and the ends of the cross-pieces are joined by strips 3 which are shorter than the distance between the cross-pieces, causing the sheet to be permanently flexed Cylindrical cams 6 are attached at either side to one end of the sheet 1 by inverted U-shaped members 4 passing through eccentric bores in the cams. Handles 7 bear against a cross-piece 8 to the underside of which are fixed two pressure plates 9. Similar cams are provided at the other end attached to the strips 3 and having their handles 7 bearing against a cross-piece 10 to which are attached plates 12 and pressure plates 11. Bows 13 are attached to the cross-pieces 8 and 10 and engage round the legs of the members 4 to allow the cross-pieces to move without becoming detached. When the sheet is concavely flexed, the turn-ups of the trousers are inserted beneath the pressure plates 9 by rotating the cam handles 7, and the trousers are similarly gripped near the crutch-piece beneath the pressure plates 11. Cover boards 14 may be inserted under the projecting edges of the plates '12 and beneath the plates 9. The flexure of the sheet 1 is reversed by applying pressure to its centre. In a modification the strips 3 are replaced by chains or cords permanently or detachably connected to hooks fixed at the ends of the sheets 1. Alternatively, the strips or chains may be omitted, the device being flexed concavely to insert the trousers and tending to return to its normal flat state on release ; or the sheet may be held in a convexly flexed position in a wardrobe. The device is also said to be applicable to tie-stretching.

Abstract: 1310645 Hydraulic pressure transformers W KIRSCHSIEPER 19 April 1971 [4 March 1970] 23130/71 Heading F1D An hydraulic pressure transformer comprises an inlet 12 and low and high pressure outlets 13, 14 communicating with a bore 2 containing a reciprocal control rod 3 having pistons 4, 5, 6. Pistons 8, 10, interconnected by rod 11, reciprocate in bores 7, 9. Ducts 15, 16, 17, 18 intercommunicate spaces in bores 2, 7, 9 as is clearly shown in the Fig. A passage 19 leads from the junction of bores 7, 9 to exhaust. In operation, and starting from the position shown, liquid enters through inlet 12 and passes to duct 18 and to the right-hand side of piston 10 which thus moves to the left forcing fluid at a lower pressure from bore 7 through duct 17 to outlet 13. When piston 10 passes over the opening into bore 9 of duct 15, then liquid passes from bore 9 through this duct 15 to the left-hand side of piston 4 thus moving the control rod 3 to the right so that piston 4 blocks outlet 13 but piston 6 uncovers outlet 14. Inlet 12 now communicates with duct 17 and thus moves pistons 8, 10 to the right to expel liquid at a higher pressure from outlet 14. When piston 10 moves past the opening of duct 16, this duct supplies fluid to the right of piston 6 to move the control rod 3 to the left to start the cycle again.
