No. 15819.—30th December, 1902.—GEORGE HENRY DUNLOP, of 17, Dundas Place, South Melbourne, Victoria, Civil Engineer. Improvements in the construction of walls or linings for tunnels and shafts.

———

Claims.—(1.) In tunnelling and in shaft-sinking, a wall or lining consisting of rings built in sections or segments, each composed essentially of ribs as a and laggings as b, substantially as described, and shown in the drawings. (2.) A wall or lining for tunnelling or shaft-sinking composed of ribs as a and laggings as b, and struts as c having, if necessary, a strengthening “sett” as e, e¹, e², flanges as f and segments as d, all secured together and arranged substantially as described, and shown in the drawings. (3.) In tunnelling and in shaft-sinking, a wall or lining consisting of ribs a, laggings b, and masonry x and struts as c when requisite, built substantially as described, and shown in the drawings. (4.) A wall or lining for tunnelling or shaft-sinking of the type specified, having the laggings as b (Fig. 4) so arranged as that they overlap, as and for the purpose described. (5.) A wall or lining for tunnelling or shaft-sinking of the type specified, having the whole of the outer surface of the lagged segments or the joints thereof covered with sheet metal, tarred felt, or other material lapped at its meeting edges to make a good joint, as and for the purpose described. (6.) In tunnelling and in shaft-sinking, a wall or lining consisting of wooden ribs as a used continuously in rings in contact, and either with or without laggings, the joint throughout being packed as specified and all arranged substantially as described. (7.) A tunnel or a shaft lining as described and shown. (8.) A tunnel or a shaft lining as described, consisting of a preliminary lining as of wood with a final lining as of concrete or other similar material, with a waterproof lining supported from within as by masonry of sufficient strength to bear the outer water-pressure, substantially as described and shown. (9.) The erection of the last section of each lining-ring with rib segments having radial joints, within a closely fitting shield, in the manner described.

No. 15820.—30th December, 1902.—MURRAY CORRINGTON, of 40, Wall Street, New York, United States of America, Counsellor-at-Law. Improvements in variable-speed safety-valves.

———

Claims.—(1.) In a safety-valve device, the combination of a piston in a chamber open on one side to fluid under pressure, a load on the other side of said piston balancing a given or normal pressure on the opposite side, and means arranged in the wall of the piston-chamber and controlled by said piston for permitting a considerable excess of pressure to escape past the piston at a continuously varying rate of speed as the load returns the piston towards its normal position. (2.) In a safety-valve device, the combination of a piston in a chamber open on one side to fluid under pressure, a load on the other side of said piston adapted to balance a given definite pressure on the opposite side, and means arranged in the wall of the piston-chamber and controlled by the movement of said piston for permitting a considerable excess of pressure to escape past said piston, slowly at first and then at an increasing rate of speed as the load returns said piston towards its normal position. (3.) In a fluid-pressure brake system, the combination, with a brake-cylinder, of a piston-chamber, a passage for permitting the pressure to escape from said cylinder through said piston-chamber, a piston in said chamber carrying a load adapted to hold it in position to close said passage when a given or normal pressure is admitted to said cylinder, and means arranged in the wall of the chamber and controlled by said piston so constructed that when an extraordinary pressure is suddenly admitted into said cylinder it will escape, slowly at first and then at an increasing rate of speed as the piston is returned by the load toward its normal position. (4.) In a fluid-pressure brake system, the combination, with a brake-cylinder, of a piston-chamber, a passage for permitting the pressure to escape from said cylinder through said piston-chamber, a piston in said chamber, a spring bearing on said piston and adjusted to hold it in position to close said passage against a given definite pressure admitted to said cylinder, and means so arranged in the wall of the chamber and controlled by said piston that when a considerable excess pressure is admitted into said cylinder the spring yields and the piston permits the pressure to escape slowly, and as the pressure falls and the spring returns the piston towards normal position the pressure escapes at an increasing rate.
(Specification, 7s. ; drawings, 1s.)

No. 15821.—30th December, 1902.—JOSEPH MOSS, of Apollo Chambers, 326, Flinders Lane, Melbourne, Victoria, Indentor. Improvements in window sashes and frames.

Claims.—(1.) The improved combination top and bottom window sash and frame consisting of a top and bottom sash in the styles of which are pivot-pins, said pivot-pins turning in slides, said slides having a wedge-shaped vertical surface on the inside of the building, and capable of moving vertically between the parting-beads of a window frame and a box frame having an upward extension above the lower or inner sash, said slides being lifted by a sash-line passing over a pulley and supporting a weight, in combination with a fastener secured above the meeting-rail of the inner sash, and a catch on the meeting-rail of the bottom sash, and a combination dust-excluding strip and lock on the inside of each style, said strip and lock having a series of oblong holes and a finger-hold, and held to the style by screws, all as and for the purposes described, and as illustrated in the drawings. (2.) The improved combination top and bottom window sashes and frames consisting of sashes having integral with or attached to the outer surface of the styles dust- and draft-excluding strips, pivot-pins attached near the middle of said styles, slides sliding between parting-beads outside said styles, a hole through each slide to accommodate a pivot-pin, dust- and draft-excluding strips on the meeting surfaces of each slide with its style, each slide being supported by a sash-line passing over a pulley and hung by a weight, a box frame having an upward extension above the lower or inner sash, in combination with a catch on the meeting-rail of the bottom sash, a fastener on the meeting-rail of the upper sash, and a casing containing a holding-pin forced outwardly by a spring secured to the meeting surface of each slide, said pin engaging with a hole in a holding-plate attached to each style, all as and for the purposes described, and as illustrated in the drawings.
