No. 11345.—26th January, 1899.—JAMES BAIRD, of Devonport, near Auckland, New Zealand, Engineer. An improved rotary engine.*

Claims.—(1.) In a rotary engine, a disc centrally mounted on shaft, said shaft passing through cylinder slightly out of centre—that is, more to top of said cylinder than to bottom, whereby a wide annular space is formed at bottom—said disc having on its inner and outer surfaces inner and outer radial piston-arms, with upright hubs or bosses, and steam-tight pieces on ends of inner arms fitted to ends of outer arms, and having slide-blocks adjusted to upright hubs or bosses, said inner and outer arms having eye-pieces placed over shaft and adjusted to one another, with an inner hub secured to or cast with central dividing-piece, and an outer hub secured to or cast with cylinder-cover fitting closely to shaft, and between said eye-pieces and shaft, for the purpose set forth, as described, and as illustrated by the drawings. (2.) In a rotary engine, inner and outer radial piston-arms, said inner arms having their outer ends extended into upright hubs or bosses and steam-tight pieces on to which outer ends of outer arms fit and form pistons which engage bore of cylinder, said upright hubs or bosses having slide-blocks adjusted to and oscillating on them, said slide-blocks carrying said arms level with inner and outer surfaces of said disc centrally mounted on shaft, said shaft passing through cylinder slightly out of centre—that is, more to top of said cylinder than to bottom, whereby a wide annular space is formed at bottom—said inner and outer arms having eye-pieces placed over shaft and adjusted to one another, with an inner hub secured to or cast with central dividing-piece, and an outer hub secured to or cast with cylinder-cover, fitting closely to shaft, and between said eye-pieces and shaft, for the purpose set forth, as described, and as illustrated by the drawings. (3.) In a rotary engine, slide-blocks adjusted to upright hubs or bosses, and oscillating on them, said upright hubs and steam-tight pieces being extensions of inner radial piston-arms on to which outer ends of outer arms fit, and form pistons which engage bore of cylinder, said slide-blocks carrying said arms level with inner and outer surfaces of said disc, centrally mounted on shaft, said shaft passing through cylinder slightly out of centre—that is, more to top of said cylinder than to bottom—said inner and outer arms having eye-pieces placed over shaft and adjusted to one another, with an inner hub secured to or cast with central dividing-piece, and an outer hub secured to or cast with cylinder-cover fitting closely to shaft, and between said eye-pieces and shaft, for the purpose set forth as described, and as illustrated by the drawings. (4.) In a rotary engine, an inner hub secured to or cast with central dividing-piece, and an outer hub secured to or cast with cylinder-cover, fitting closely to shaft and between eye-pieces of inner and outer radial piston-arms, said inner arms having their outer ends extended into upright hubs or bosses, and steam-tight pieces on to which outer ends of outer arms fit and form pistons which engage bore of cylinder, said upright hubs or bosses having slide-blocks adjusted to and oscillating on them, said slide-blocks carrying said arms level with inner and outer surfaces of said disc centrally mounted on shaft, said shaft passing through cylinder slightly out of centre—that is, more to top of said cylinder than to bottom, whereby a wide annular space is formed at bottom—for the purpose set forth as described, and as illustrated by the drawings. (5.) In combination in a rotary engine, a cylinder having a central dividing-piece with a hub secured to or cast with same, said hub bored to hold and holding shaft slightly out of centre—that is, more to top of said cylinder than to bottom—said shaft having a disc so centrally mounted on it and within said cylinder that a wide annular space is formed at bottom of cylinder, which said annular space receives either water, steam, compressed air, gas, elastic fluid, or any other suitable form of power which may be used to actuate pistons and said disc, said disc having on its inner and outer surfaces inner and outer radial piston-arms with upright hubs or bosses and steam-tight pieces on ends of inner arms fitted to ends of outer arms, thereby forming pistons, and having slide-blocks adjusted to upright hubs or bosses, said inner and outer arms having eye-pieces placed over shaft and adjusted to one another, with said inner hub on central dividing-piece and outer hub secured to or cast with cylinder-cover, fitting closely to shaft and between said eye-pieces and shaft, said disc having packing or steam-tight rings kept in place by springs and packing-pieces let into ends of steam-tight rings, said cylinder-cover securely fastened to cylinder and right and left ports, for the purpose set forth as described, and as illustrated by the drawings.

No. 11356.—2nd February, 1899.—WILLIAM ERNEST HUGHES, of 54, Lambton Quay, Wellington, New Zealand, Patent Agent (nominee of Egbert Moore Tingley, of Amber Club, Pittsburg, Pennsylvania, United States of America, Electrical Engineer, and Mary Woolslair Shallenberger, of Madison Street, Rochester, Pennsylvania aforesaid, executrix of Oliver Blackburn Shallenberger, deceased, joint inventor with the said Egbert Moore Tingley). Improvements in phase-adjusting, and regulating methods and means for alternating-current apparatus.

Claims.—(1.) The method of adjusting an existing difference of phase between two magnetic fields produced by two coils caused by placing an inductive resistance in series with one of the coils, which consists in shunting this coil with a non-inductive resistance, so as to still further retard the phase of the current flowing in said coil, as described. (2.) The modification of the invention wherein one of the coils is not directly connected with the main circuit, but is included in the secondary circuit of a transformer, the other of the coils having an inductive resistance in series, as described. (3.) The method of obtaining a desired difference of phase between two magnetic fields produced by two coils, which consists in energizing one of the coils from a transformer wound with two or more primary coils, the currents in said primary coils having a difference of phase, substantially as described. (4.) An electric measuring-instrument provided with the various means of securing a desired difference of phase between the two operative magnetic fields, substantially as described with reference to the drawings.
