No. 19741.—13th July, 1905.—EDWARD SPREY, of Montreal and Salisbury Streets, Christchurch, New Zealand, Hawker. Improved spring hooks and eyelets.

Claims.—(1.) In hooks and eyelets, single-pointed hooks bent and arranged so as to spring into a sheath and to be opened for hooking or unhooking by being pressed on the body of same, in combination with raised eyes, the whole secured to the proper portions of the fabric to be hooked by eyelets, all substantially as set forth, and as illustrated in the drawing. (2.) In hooks and eyelets, double-pointed hooks arranged by being bent to spring open, in combination with pairs of eyelets, said hooks being closed sufficiently to enter or withdraw by pressing their body, all substantially as set forth, and as shown on the drawing. Hooks formed substantially as set forth and as shown on the drawing, secured to one edge or end of a fabric, in combination with eyes or eyelets secured to another edge or end to be hooked together, said hooks having their bodies pressed or closed when hooking or unhooking, all substantially as set forth and for the purposes indicated.

No. 19761.—20th July, 1905.—WILHELM SCHMIDT, of Wilhelmshohe, near Cassel, Hesse-Nassau, German Empire, Civil Engineer. Improvements in packing check-ring devices for piston slide-valves.

Extract from Specification.—The subject of my invention now consists in means for laterally pressing fast the gas-check rings in certain positions, but at times releasing the rings again. For this purpose a comparatively great lateral pressure is necessary, which is obtained by sparing out the piston-slide in the middle down to the piston-rod and arranging upon this side of the piston-slide a flexible or axially movable pressure-plate of great surface so that the inside steam-pressure can firmly press the rings in certain positions against the outside surfaces of the piston-slide.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19766.—20th July, 1905.—PATRICK SARSFIELD TRIGGS, of 80, Ladbrooke Grove, London, England, Engineer. Improvements in and relating to disintegrating-machines.

Claims.—(1.) The combination with a revolving disintegrating-drum of a rebounding device or roof partly surrounding it, and consisting of a series of rounded pockets, substantially as described. (2.) The combination with a revolving disintegrating-drum provided with triangular teeth of a rebounding device or roof partly surrounding it, and consisting of a series of rounded pockets, substantially as described.

(4.) A locomotive tube boiler with superheating-tubes arranged in some enlarged smoke-tubes of the boiler, the ends of the superheating-pipes being bent backwards in such a manner that they are turned backwards into the direction of the tube-plate of the smoke-box, the ends of the tubes being tightened to steam-chambers by flanges firmly attached to the ends of the superheating-tubes, the front of the steam-chambers is in an upright position and directed towards the door of the smoke-box of the boiler, substantially as and for the purpose set forth. (5.) A locomotive tube boiler with superheating-tubes arranged in some enlarged smoke-tubes of the boiler, the ends of the superheating-pipes being bent backwards in such a manner that they are turned backwards into the direction of the tube-plate of the smoke-box, the ends of the tubes being tightened to steam-chambers by flanges firmly attached to the ends of the superheating-tubes, the front of the steam-chambers is in an inclined position and directed towards the door of the smoke-box of the boiler, substantially as and for the purpose set forth. (6.) A locomotive tube boiler with superheating-tubes arranged in some enlarged smoke-tubes of the boiler, the superheating-pipes arranged as outward and return flue conduits, and their ends being bent backwards in such a manner that they are turned backwards into the direction of the tube-plate of the smoke-box, the ends of the tubes being tightened to steam-chambers, the front of which is in an upright position and directed towards the door of the smoke-box of the boiler, substantially as and for the purpose set forth. (7.) A locomotive tube boiler with superheating-tubes arranged in some enlarged smoke-tubes of the boiler, the superheating-pipes arranged as outward and return flue conduits, and their ends being bent backwards in such a manner that they are turned backwards into the direction of the tube-plate of the smoke-box, the ends of the tubes being tightened to steam-chambers, the front of which is in an inclined position and directed towards the door of the smoke-box of the boiler, substantially as and for the purpose set forth.
