[No. 88

No. 19909.—22nd August, 1905.—BENJAMIN LOCKING, of Tennyson Street, Napier, Hawke’s Bay, New Zealand, Medical Practitioner. Improved apparatus for generating gases to be used for poisoning and disinfecting purposes and the like.

Extract from Specification.—According hereto the combustion-chamber in which the gas is generated is arranged within an outer vessel containing water, and the gas is led through a coiled pipe surrounded with water before it is discharged into the pipe which conveys it to the place where it is to be used. The fan or blower conveying air to the combustion-chamber is carried upon a vertical tube, which is fitted telescopically upon a cylindrical extension from the combustion-chamber.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19914.—22nd August, 1905.—GODFREY BENINGTON JOHNSON, of 8, Victoria Street, Westminster, London, England, Engineer. Improvements in machinery for bringing metal strips and sheets to a curved form in cross section.

Extract from Specification.—According to the present invention each of the rolls for producing a number of corrugations or contours of reverse curvature side by side in a sheet of metal comprise an arbor and a series of roll sections independently splined thereon and normally held a predetermined distance apart by spring pressure, each section comprising a salient portion of the roll contour, and the sections of successive pairs of rolls being of progressively diminishing width and mounted at progressively diminishing distances apart in accordance with the progressive diminution in the effective width of the sheet of metal during its passage through the machine. The arrangement is such that as a pair of rolls operate upon the sheet the sections of each roll of the pair will approach one another by sliding upon the arbor in accordance with the contraction simultaneously produced in the effective width of the sheet owing to the concurrent deepening of the corrugations, the normal distance apart of the sections of successive pairs of rolls being so adjusted that the sheet will be prepared by the action of one pair of rolls for entry between the next succeeding pair, and will thus be subjected to a gradual and continuously progressive process of cross-bending without suffering from sudden or violent strains.

No. 19916.—22nd August, 1905.—JOHN RUTHERFORD PARK, of 55, Lambton Quay, Wellington, New Zealand, Registered Patent Agent (nominee of Carl Weber, of 159, La Salle Street, Chicago, Illinois, United States of America, Civil Engineer). Improvement in chimneys.

Claims.—(1.) A chimney having its base and superstructure formed of concrete, reinforced by metal beams embedded therein, with the lower section rising from said base composed of an outer wall and an inner wall forming an interposed air-space with or without air-admission ports in said outer wall, and the upper section composed of a single wall, characterized by the inner wall being free at its upper end from the outer wall, and thus contractible and expansible independently thereof. (2.) The chimney described in preceding claiming-clause 1, characterized by an annular expansion-chamber in the inner surface of the outer wall near the junction of the lower double-walled and upper single-walled sections, into which expansion-chamber the upper end of the inner wall of the air-space extends to permit free expansion and contraction of said inner wall. (3.) The chimney constructed as shown and described.

No. 19924.—23rd August, 1905.—BRAIM PATENT SWITCH COMPANY, LIMITED, of 800, Hastings Street West, Vancouver, British Columbia, Canada (assignees of William Henry Braim, of Vancouver aforesaid, Motorneer. Means for operating a street-railway switch from an approaching car.

Extract from Specification.—As a car approaches the junction the motorneer lowers the lever 31 that its end 30 may engage either 15 or 26 as he requires to take the junction or proceed on the straight track, and the slidable block engaged is moved along its slot to effect the desired movement, being automatically disengaged at the limit of its movement by the raised portion 41 at the end of the slot, and the switch-blade is retained in the position it is moved to and the recoil prevented by the spring 12 in the lever-box 6.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 7s.; drawings, 2s.)

No. 19926.—23rd August, 1905.—GEORGE LINDSEY, of “Culloden,” Livingstone Road, Marrickville, near Sydney, New South Wales, Australia, Brewer. Improved means for filling casks and other vessels with liquid.

Claims.—(1.) Improved means for filling casks or other vessels with liquid consisting of a plug or cup fitting in the filling-orifice and provided with a passage for the filling-pipe, and a chamber or recess having an inlet communicating with the interior of the vessel and an outlet communicating with the atmosphere, said outlet being capable of closure by a ball or other float, substantially as described. (2.) In means for filling casks or other vessels, the combination with the filling-orifice, of a plug such as 4, passage such as 7, chamber such as 10, inlet and outlet passages thereto such as 11 and 12, and float such as 13, substantially as described and explained, and as illustrated in the drawings.
(Specification, 2s. 3d.; drawing, 1s.)

No. 19927.—23rd August, 1905.—SIDNEY READ BELLINGHAM, of Rydal, New South Wales, Australia, Artist. Improvements in animal-feed boxes.

Extract from Specification.—A movable nose-board attached to a flexible false wall is situated within the feed-hopper and adapted to automatically control the supply of feed therefrom to the box proper. By this arrangement there is only a small quantity of feed in the box at a time, and when said box is empty it is replenished by the movement of the animal’s nose whilst eating, engaging the nose-board, which causes a reciprocatory movement of the flexible wall and allows a small quantity of feed at the discharge end of hopper to fall.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 4s. 6d.; drawing, 1s.)

No. 19930.—24th August, 1905.—PAUL SCHOU, of 257, Vesterbrogade, Copenhagen, V., Denmark, Civil Engineer. Improvements in thrust-bearings for revolving shafts.

Extract from Specification.—The elastic effect of the bearing is obtained by inserting a ring filled with fluid between the bearing itself and the part of machinery surrounding same, and the principal feature of the invention is that the whole surface of the said fluid-ring is arranged to bear against the walls of the said parts even if these move in relation to one another; consequently the elastic walls of the fluid-ring itself will never at any point be freely exposed, and may therefore be made quite thin.

No. 19931.—24th August, 1905.—CHRISTOPHER BURTON, Clockmaker, ALEXANDER IRONSIDE LITTLEJOHN, Jeweller, and PETER STILL, Jeweller, all of 85, Lambton Quay, Wellington, New Zealand. An improved apparatus for straining wires and the like.

Claims.—(1.) Apparatus for the purpose indicated, comprising, in combination, a bar, a hood integral with each end of the bar, there being a slot through one side of each hood, the top of each hood sloping downwardly to its end of the bar, a disc within each hood, an arm projecting forwardly and laterally from one hood, an operating-lever fulcrumed to the arm by a pin, a second bar pivoted to the lever, and a hood integral with the end of the bar and having a slot through one of its sides, and having a top sloping downwardly to the end of the bar, substantially as set forth. (2.) Apparatus for the purposes indicated, comprising, in combination, a bar, a hood integral with and upon each end of the bar, there being a slot through one side of each hood, the top of each hood sloping downwardly to its end of the bar and having a circumferential groove, a bar across the larger end of the hood, an arm projecting forwardly and laterally from one hood, an operating-lever fulcrumed to the arm by a pin, a second bar pivoted to the lever, and a hood integral with the bar and having a slot through one of its sides, and having a top sloping downwardly to the end of the bar, substantially as set
