No. 12787.—14th July, 1900.—JAMES RAPSON, Blacksmith, and JOHN RAPSON, Engineer, both of Kakanui, New Zealand. An improved wire strainer, cutter, and key combined.

Claims.—(1.) An improved wire-strainer, with a table frame in combination with perpendicular sides, having on one end four feet for straining to posts, such as C1 and C2 on No. 1, as illustrated. (2.) In an improved wire-grip with corrugated faces A and A1, such as shown on No. 2, A being worked by a small lever A¹, self-adjusting, which, by eccentric motion, feed together, and renders slipping impossible. (3.) In an improved wire-cutter, such as shown on No. 2, a lever having a round cutting-end, which can be removed by the screw C, and by the motion of leverage cuts against cutter g, which also has a cutting-edge; it is removable by the screw D, and can be adjusted by the screws J when the edges have become worn or short by sharpening. Being made of the best steel, and having a 9 in. lever, operates easily. Having no spring or sliding-knives which will not operate when they become wet and rusty, it cannot get out of order. When in operation the lever is open, such as shown on No. 2, and opens the cutters to admit the wire. In closing the lever the cutting-edges come together, and are prevented from touching by the lever coming against the slot T, beneath the frame, and is held in position by the catch M, such as shown on No. 3. (4.) In an improved hook B, such as shown on No. 6, having a slot on the top side to lead the wire into the wire-grippers. (5.) In an improved clip H, such as shown on No. 5, forming a part of the frame; the strong spring E, as shown on No. 2, keeps the wire firmly down in its place, so that the wire cannot get out and the machine tip over when winding. (6.) In an improved removable barrel without flanges, so that should the wire break on the barrel while winding it can be easily removed. (7.) The advantage gained by the frame being 14¾ in. long is to obtain leverage on the winding-handle and the cutter. It also offers resistance from tipping when beginning to wind slack wire. (8.) The advantage of the wire-grip is to prevent turning over the machine when forming the loop, as it is very liable to break old wire while the strain is on the barrel.

(2.) In a draught-excluder for doors, the combination with a spring-raised draught-excluding strip C of the parts referred to by the letters H to M, all located and operated substantially as and for the purposes set forth and illustrated. (3.) In a draught-excluder, the combination with a spring-raised draught-excluding strip C of the parts referred to by the letters J to M, all located and operated substantially as and for the purposes set forth, and as illustrated.

No. 13140.—7th November, 1900.—EDWIN ARNOLD, of Willis Street, Wellington, New Zealand, Manufacturer. Improvements in wire-wove spring mattresses.

Claims.—(1.) In wire-wove spring mattresses, an elastic strip secured to the mattress-frame, and passing transversely beneath the mattress, in combination with a number of helical springs attached to a transverse batten secured beneath the strip, such helical springs pressing against the strip and forcing it into contact with the under-side of the mattress, as and for the purposes set forth. (2.) The general arrangement, construction, and combination of parts in my improvements in wire-wove spring mattresses, as described and explained, and for the purposes set forth.

No. 13141.—7th November, 1900.—SIDNEY READ BELLINGHAM, of Glen Hill, near Picton, New South Wales, Artist; DAVID FELL, of Equitable Buildings, George Street, Sydney, New South Wales, Public Accountant; and NORMAN PHELPS RICHARDS, of 384, George Street, Sydney aforesaid, Merchant. Improvements in receptacles or containers for discrete materials, whereby arbitrary portions may be withdrawn.

Claims.—(1.) In receptacles or containers of the class set forth, the combination with the body thereof of a sliding vertical door adapted normally to press downwardly and close a wedge-shaped scoop or drawer adapted to slide under said door, and a shelf or bottom extension of the receptacle below and outwardly of said door, substantially as described and explained. (2.) In receptacles or containers of the class set forth, the combination with a sliding spring or weighted door and a wedge-shaped scoop or drawer of protector-pieces on the side walls of the body or of recesses therein, for the purpose set forth, substantially as described and explained, and as illustrated in the drawings. (3.) In receptacles or containers of the class set forth, the combination with a sliding spring door and a wedge-shaped scoop or drawer of a hinged or spring shelf or a spring liner adapted to rise upwardly at the front of said drawer or scoop, substantially as described and explained, and as illustrated in the drawings. (4.) The combination and arrangement of mechanical parts, all together forming receptacles or containers for discrete materials, whereby arbitrary portions may be withdrawn, substantially as described and explained, and as illustrated respectively in Fig. 1, in Fig. 2, in Fig. 3, in Fig. 4, and in Fig. 8 of the drawings.

No. 13142.—7th November, 1900.—WILLIAM LINDSAY CORSON, of San Francisco, California, United States of America, Mechanical Engineer. Exhaust mechanism for explosive engines.

Claims.—(1.) In an explosive engine, the combination with the exhaust-chamber of a hollow exhaust-valve arranged therein, and of means for supplying a cooling medium to the interior thereof. (2.) In an explosive engine, the combination with the exhaust-chamber of a hollow exhaust-valve arranged therein, of means for supplying a cooling medium to the interior of the valve, and of means for maintaining the cooling medium within the valve until a predetermined level has been reached. (3.) In an explosive engine, the combination with the exhaust-chamber of a hollow exhaust-valve arranged therein for controlling the exhaust-port of the exhaust-chamber, said valve being provided with a hollow body of less diameter than that of the valve, and of means for supplying a cooling medium to the hollow valve. (4.) The combination with a hollow exhaust-valve of a hollow stem extending therefrom, a tubular extension secured to the valve, and of means for supplying a cooling medium through the tubular extension to the interior of the valve, the hollow stem communicating with the interior of the valve and serving as an outlet for the cooling medium.

(6.) The combination with an exhaust-valve for explosive engine of a body portion of less diameter than the valve proper, a stem extending from the valve, of means actuated by the engine for raising the valve from its seat, a spring for holding the valve to its seat, and of means for maintaining the valve cool during the working of the engine. (7.) The combination with the exhaust-chamber of an explosive engine of the exhaust-valve arranged therein, said valve being provided with a body portion of less diameter than the valve, a sleeve or collar removable secured within the exhaust-chamber, a stem extending from the valve, a spring for holding the valve to its seat, devices operated by the movement of the engine for raising or unseating the exhaust-valve, and of means for maintaining the valve cool during the working of the engine.
