Granted: 1902-11-06
Abstract: 19,738. Lorie, A. F. W. July 19, [date applied for under Patents Act, A.D. 1901]. Window holders. -In order to secure a window either in a closed or an open position, a screw working in a nut fixed to the lower sash engages a plate fixed to the side rail of the upper sash. The end of the screw may be flat, pointed, or chisel-shaped, and the plate is formed with corrugations, serrations, or perforations. A counterbalanced hook-shaped lever or catch may be secured to the window frame to engage the screw, when the bottom sash is down, and thus lock the sash in position. The end of the screw may be formed with a stop to engage a recess in the nut. Fig. 17 shows a system of operating-levers arranged in connection with the screw. The screw, which works in the nut 6 and is adapted to engage a plate 1, has a cranked end 9 connected by levers 13, 19 to a lever 24. The screw and levers are connected together by knuckle-joints, and the lower end of the lever 24 slides in guides secured to the bottom of the sash. Each guide consists of a base-plate carrying two spindles connected by a plate 42, the lever sliding between pulleys 43 mounted on the spindles so as to have a longitudinal as well as a rotary motion. Upon lifting the lever 24, the screw is turned to release the top sash, and upon releasing the lever, it falls to secure the sashes together. A counterbalanced hook 25, pivoted to a plate secured to the frame, may engage the bent end of the lever 24 when the bottom sash is in the lowered position, to lock it in the closed position. In the arrangement shown in Fig. 14, the screw 5 is turned to release the top sash by means of a chain 32 passing over a pulley 29 on the screw spindles. A spring enclosed in a casing 36 controls the screw and returns it to the locking position on the release of the chain. The pivoted catch 25 is secured to the window frame and is arranged to engage the screw when the bottom sash is closed. In a modification, shown in Fig. 12, the screw is replaced by a spindle 5<c> having a spiral groove to engage a pin 6<c> in the spindle casing. The spindle is moved in one direction by a spring 34<e>, one end of which is secured to the spindle and the other to the casing.

Casting and moulding.-A yielding and collapsable core of the type described in Specification No. 19,934, A.D. 1902, is used to obtain chill castings in iron or hollow castings in steel, copper, aluminium, brass, or other metals or alloys. The cylindrical core bar e consists of a number of seg. ments, bolted together and to spiders h, and serving as guides for radial bars l, 4, to which the segments j<1> and the filling-strips y forming the chill surface are, respectively, connected. The chill segments are expanded and contracted by eccentrics o on vertical shafts m engaging recesses in the bars l, while the bars 4 are operated by eccentrics on a central shaft 6. The segments move on balls 10 on a plate a, on which the core bar is placed, the plate being fixed by screws c and cottars on a table b, on which the mould is placed. Some of the segments may be formed in parts hinged together, and may be provided with holes 13<a> filled with leam to diminish the chilling effect on parts of the casting, as in the case of casting cylinders with steam ports &c. Loam may be inserted in various parts 13 of the segments to facilitate the pouring of the metal. The whole of the parts are secured in position, when adjusted, by bolts 7, which also secure a plate 8 with a suspension ring 9. When the metal has commenced to set, the filling-pieces are withdrawn and the shafts m are slightly turned so that the segments may be collapsed by the contraction of the metal. The shafts m, 6 may be adjusted from above or below the mould. The joints between the parts of the chill surface may be filled with plumbago or other refractory material, and are locked in their adjusted position by a four-arm frame, centered on the shaft 6, and having snugs on the boss and at the ends of the arms to engage recesses in collars on shafts when the frame is lowered into the locking position. The invention may be used in the casting of chilled cylinders for steam, oil, &c. engines, or chilled turbine casings, &c. or in casting metals or alloys which contract to a considerable extent during cooling.

Abstract: 505. Anderson, H. P. H., and Wilding, J. Jan.8. Lift valves; selfclosing valves; pressure - regulating valves.-The selfclosing valve, shown in Fig. 1, comprises a lift valve B, seating against a web a in the casing, an attached piston B<3>, sliding through hat-leather or like packing at the lower end of a cushioning- chamber D, and an attached stem terminating in a push-knob B<2> outside. The valve consists, preferably, of a leather or composition disc B secured by a nut F. The cushion chamber D and the inlet side of the valve are connected by a hole d in the valve-stem, a non-return ball valve being fitted in the nut F to close the inlet orifice of the hole. When the knob is pressed down to open the valve, water passes through the stem into the chamber D. On releasing the knob, the fluid pressure acts to close the valve, but the closing is resisted by the fluid in the chamber D ; this fluid is gradually discharged through the bye-pass G to the inlet, the time taken being regulated by a cock g. Concussion is thereby prevented. In a modification, the valve is opened by a cam lever. Two or more valves may be connected together, and operated by levers. The stop valve, shown in Fig. 5, is operated by a cam lever and has the end of the spindle screwed and fitted with a hand-wheel for holding the valve against its seat. Fig. 7 shows the invention adapted to a reducing-valve ; the stem B<1> slides in a guide part of the casing, and a spring J is provided to counteract the fluid pressure.
