No. 14336.—16th December, 1901.—THOMAS SUMMERTON, Jun., of Armagh Street, Christchurch, New Zealand, Engineer. Improvements in mechanism for operating venetian blinds.*

Claims.—(1.) The combination in apparatus for the purpose indicated of a drum having recesses upon its circumferential periphery, and revolving with the cord-pulleys of a venetian blind, operating-cords passing over said cord-pulleys, a pivoted trip-lever, the rear end of which has a projection adapted to engage in any one of said recesses, a cross-bar at the forward end of said trip-lever, and pivoted grip-levers serrated at their lower ends and having projections from their upper ends adapted to be engaged by said cross-bar when the rear end of the trip-lever is raised, as specified. (2.) The combination in apparatus for the purpose indicated of grip-levers having serrations at their lower ends, said levers being pivoted above the operating-cords of a venetian blind and normally tending to grip same by the weight of the blind upon the cords, projections from the grip-levers, a pivoted trip-lever having a bar adapted to engage such projections, a projection from the rear end of the trip-lever adapted to engage in any one of a plurality of recesses in the periphery of a drum revolving with the pulleys which guide the operating-cords, as specified. (3.) The improved apparatus for operating venetian blinds consisting of the parts arranged, combined, and operating substantially as and for the purposes specified, and illustrated in the drawings.

No. 14451.—20th January, 1902.—CATHERINE ESTHER BAMFORD, of Hautapu, Rangitikei, New Zealand, wife of Frederick Bamford. An improved means of preventing young children falling out of bed.

Description of Invention.—This invention is intended to prevent children falling out of bed and thereby injuring themselves. It consists of a strap which is placed round the child’s waist and fastened in the ordinary way by a buckle or other suitable contrivance. Secured at right angles to this strap, about half-way between the buckle and the other end, is another strap. This second strap is of sufficient length so that when in use it can be carried up under the pillow and be fastened to the bedstead. To enable the strap to be conveniently secured, I attach a short length of strap to it and provide this small strap with a buckle, with which the end of the long strap engages after passing round the bedstead.

Claim.—The means for preventing children falling from beds, consisting of the set of straps arranged and operating substantially as described.
(Specification, 1s.)

No. 14452.—21st January, 1902.—ADOLPHUS JAMES PARK, of Ngaruawahia, Auckland, New Zealand, Engineer. Improved means for delivering steam into steam heating-appliances.

Claim.—In means for delivering steam into steam heating-appliances, a nozzle adapted to be screwed on to the steam-pipe, in combination with a pipe or hollow casing surrounding the nozzle and formed with a number of apertures therein, behind the opening of the nozzle, as specified.
(Specification, 2s.; drawings, 1s.)

No. 14480.—29th January, 1902.—THE WILFLEY ORE-CONCENTRATOR SYNDICATE (LIMITED), of 7-11, Moorgate Street, London, England (assignees of Arthur Redman Wilfley, of Denver, Arapahoe, Colorado, United States of America, Engineer). Improvements in ore-concentrators.

Claims.—(1.) In an ore-concentrator, the combination with a base or bed frame, and a table or deck supported thereby and adapted to move with respect thereto, of wedges interposed between said parts at opposite sides thereof, and means for simultaneously shifting said wedges whereby to raise one edge of the deck or table and lower the other, substantially as specified. (2.) The combination with a base or bed frame, and a table or deck supported thereby and adapted to move with respect thereto, of oppositely inclined wedges interposed between said parts at opposite sides thereof, rods connecting the sets of wedges together, racks on said rods, a rock shaft, means for rocking the latter and pinions on the rock shaft engaging the rack-teeth on the rods for reciprocating the latter simultaneously in one direction or the other, whereby the deck or table is simultaneously raised at one edge and lowered at the other, substantially as specified. (3.) The combination with a bed or base frame, rods having sliding connection therewith and carrying wedges, the wedges on the two rods inclining in reverse directions, said rods having rack-teeth, a rock shaft having pinions which engage said rack-teeth, and an intermediate frame supported by the bed or base frame in position so that its opposite edges are simultaneously raised and lowered as a result of the endwise movement of the rods which carry the wedges, of a concentrating deck or table having reciprocating connection with the intermediate frame, substantially as specified. (4.) The combination with a base or bed frame, and a concentrator-table having sliding connection therewith, of a draw or thrust bar connected with the table at one end, means for supporting it at the other end, means for positively moving the draw or thrust bar in one direction, and tension-mechanism against which the bar abuts as it is moved in one direction, and which gives pressure to it in its opposite movement, substantially as specified. (5.) The combination with a base or bed frame and a concentrator deck or table constructed and adapted to move with respect thereto of a fixed post or abutment secured upon the frame, a spring-actuated abutment or bridge-piece connected with the frame, a draw or thrust bar extending between the table to which it is attached and the bridge-piece or movable abutment against which it abuts, toggle-mechanism interposed between the draw or thrust bar and the fixed post or abutment, a crank-shaft and a pitman extending from the latter to the toggle-joint, substantially as specified. (6.) The combination with a base or bed frame and a concentrator deck or table constructed and adapted to move with respect thereto of a fixed post or abutment secured upon the frame, a spring-actuated abutment or bridge-piece connected with the frame, a draw or thrust bar extending between the table to which it is attached and the bridge-piece or movable abutment against which it abuts, toggle-mechanism interposed between the draw or thrust bar and the fixed post or abutment, a crank-shaft, a pitman extending from the latter to the toggle-joint, and means for adjusting one end of the toggle-joint with respect to the fixed post or abutment, substantially as specified. (7.) The combination with a base or bed frame and a concentrator deck or table constructed and adapted to move with respect thereto of a fixed post or abutment secured upon the frame, a spring-actuated abutment or bridge-piece connected with the frame, a draw or thrust bar of skeleton form having a hollow interior, said draw or thrust bar extending between the table to which it is attached and the bridge-piece or movable abutment against which it abuts, toggle-mechanism interposed between the draw or thrust bar and the fixed post or abutment, a crank-shaft, a pitman extending from the latter to the toggle-joint, the toggle, pitman, and fixed post extend-
