Claims.—(1.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte liquid, of a shaft above the same provided with a coating of insulating material for supporting and rotating the coil, an anode located within said tank, and a cathode connection between the coil and said shaft, substantially as described. (2.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte liquid, of a shaft above the same provided with a coating of insulating material for supporting and rotating the coil, an anode located within said tank, and a cathode connection between the coil and said shaft, and a partition located in said tank between the anode and said coil and extending from the top of the tank to a point adjacent to the bottom thereof, substantially as described. (3.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte liquid, of a shaft above the same provided with a coating of insulating material for supporting and rotating the coil, an anode located within said tank, and a cathode connection between the coil and said shaft, and a partition located in said tank between the anode and said coil and extending from the top of the tank to a point adjacent to the bottom thereof, a compartment located within the coil to be acted upon and provided with apertures for the circulation of the electrolyte, and an anode located in said compartment, substantially as described. (4.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte, of a shaft above the same provided with a smooth coating of insulating material, collars of insulating material to prevent the endwise movement of the coil and collars, of conducting material to engage the end of the coil, an anode within said tank, and a cathode connection with said conducting-collars, substantially as described. (5.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte, of a supporting-shaft of smaller diameter than the coil of mother-wire for supporting said coil, said shaft being provided with a coating of insulating material, means for rotating said shaft, a cathode connection between said coil and said shaft, and coil-engaging devices on said shaft for retaining the coil against lateral movement, substantially as described. (6.) In apparatus for the manufacture of wire or the like by electro-deposition upon a mother-wire in the form of a coil, the combination with the tank for containing the electrolyte, of a supporting-shaft of smaller diameter than the coil of mother-wire for supporting said coil, said shaft being provided with a coating of insulating material, means for rotating said shaft, a cathode connection between said coil and said shaft, and struts secured to said coil for preventing the lateral movement of the convolutions thereof, substantially as described.

No. 14867.—1st May, 1902.—ROBERT STUART REID, of Timaru, New Zealand, Surgeon. Improvements in or relating to windows.*

Claims.—(1.) In windows, a toothed rack secured to the face of the top sash and upon the edge thereof, a sliding spring bolt secured transversely within the sash-slides of the window-frame and provided with a tooth normally engaging with the rack and with a pin projecting into the slide of the bottom sash, in combination with an inclined surface upon the edge of the bottom sash that is adapted to engage with the bolt-pin so as to free its tooth from the rack when the sash is raised, and with means for locking the lower sash in its closed position, as set forth. (2.) In means for locking windows, a pendant pivoted hook secured within a cavity in the bottom end of the lower sash-frame, provided with an inclined surface on its lower end and with a spring bearing against its back side, an upright staple secured upon the window-frame with which the hook will engage when the sash is lowered, and a push upon the inside face of the sash-frame whereby when the lower sash is down the upper sash may be locked in any position from further opening, and when the lower sash is raised the upper sash will be unlocked, as specified. (3.) In windows, a toothed rack upon the inside face of the top sash, a transverse sliding spring bolt within the sash-slides of the frame provided with a tooth normally engaging with the rack and with a pin projecting into a vertical groove upon the edge of the bottom sash, and an inwardly inclined surface upon one side of the groove, in combination with a pivoted spring hook mounted in a cavity formed in the bottom end of the lower sash, such hook being provided with an inclined undersurface and adapted to engage with an upright staple secured to the frame of the window when the sash is down, and a push for freeing such hook from the staple, as specified.
