for supporting the tread-face of the sole, and, if desired, for assisting in the bending operation. (2.) In a machine such as is described in claiming clause 1, mechanism for causing the tool to oscillate about an axis at or near its operating-tip, and preferably in a plane approximately at right angles to the sole. (3.) A machine for shaping portions of a shoe, having means for bending the marginal portion of the sole, and for shaping the adjacent portion of the upper, comprising a vibratory carrier provided with a sole-bending tool adapted to enter the crease between the upper and the sole, and a blocking-device mounted in the carrier in position to engage the upper. (4.) A machine for operating upon a shoe-sole, having a rotary pressing and wiping member which, if desired, is provided with yielding peripheral segments, and which, by the combination of a wiping action and a succession of pressing actions or blows, returns or forces the marginal portion of the sole to or beyond its original plane or forces it out of that plane. (5.) A machine for shaping a portion of a shoe, means (for example 14) arranged to act upon the sole for bending its marginal portion and for simultaneously laying the channel-flap, with or without a cooperating vibratory tool (for example 16) or other support either for assisting in bending the sole or merely for supporting said marginal portion. (6.) Mechanism for laying a channel-flap, or for bending a sole, or for both, comprising a rotary hub, a plurality of segments pivoted to the hub and provided with oblique or other ribs, and a spring interposed between two adjacent segments and tending to swing them in the same direction about their pivots. (7.) The combination of the mechanism described in claiming clause 6 with means for rotating the hub and connected parts in the direction in which the work is fed, together with a rest or gauge for the edge of the sole. (8.) In a machine of the class described, a shaft provided with an extension the axis of which is oblique to the axis of the shaft, a sleeve on the extension, a tool arranged to be vibrated for the purpose of shaping a portion of a shoe, a carrier for said tool constructed to vibrate about an axis which does not intersect the axis of said shaft, but which preferably is at or near the operating-tip of the tool, together with connections from said sleeve to said carrier.

No. 21101.—8th May, 1906.—FRANCIS JOSEPH McCARTY, of No. 1022 Mills Building, San Francisco, California, United States of America, Electrician. Wireless telephone.

Claims.—(1.) In a telephone, an induction-coil consisting of a plurality of primary coils and a secondary coil, a double transmitter, alternately acting contacts upon opposite sides of one transmitting-diaphragm, and connections between said contacts and with one of the primary coils. (2.) In a telephone, a mouthpiece, a transmitting-diaphragm with contacts upon opposite sides disposed to alternately complete and interrupt circuits through each pair of contacts when energized, metallic connections between the exterior elements of said contacts, an induction-coil, and connections between the contacts and said coil. (3.) In a wireless telephone, a mouthpiece, a transmitting diaphragm with connected metallic contacts upon opposite sides, an induction-coil and battery and connections with the transmitter, a microphone transmitter actuated in unison with the first-named transmitter, a second primary winding of the induction-coil connected with the microphone transmitter, and a battery interposed between said transmitter and the connected primary winding of the coil. (4.) In a telephone, means introduced into the primary circuit, said means comprising a plurality of primary windings whereby a secondary coil is energized, a mouthpiece, a transmitting-diaphragm with metallic contacts connected upon opposite sides, and a microphone transmitter, means whereby a spark is produced and the aerial transmitting medium is affected to transmit articulate speech, and a receiving mechanism having a variable coherer and capable of receiving transmitted speech. (5.) In a telephone, means introduced into transmission-devices comprising a double transmitter, said transmitter including a mouthpiece, a transmitting diaphragm with metallic contacts upon opposite sides, an induction-coil and battery and connections with the transmitter, primary coils and a secondary coil energized thereby, means whereby a spark is produced and the aerial transmitting medium is affected between the sending and receiving mechanism to transmit articulate speech. (6.) In a telephone, means introduced into the transmission-devices, including an induction-coil and connections with the transmitter, whereby the aerial transmitting medium is affected to transmit articulate speech.

No. 21114.—9th May, 1906.—HENRY WALLACE McCLELLAN, of No. 3, Henry Street, Hawthorn, Victoria, Australia, Plumber. Improvements in gas water-heaters.*

Claims.—(1.) In a gas water-heater, the described means of insuring the liberation of any gas accumulated in the casing of the heater before the gas-burner can be lighted. (2.) A gas water-heater having the gas-supply tap situate within its cylindrical casing, said casing having a hinged door extending the whole or a portion of its side, as and for the purpose specified. (3.) In a gas water-heater, means for automatically regulating the supply of gas to the burner by the quantity of water supplied, substantially as set forth. (4.) In a gas water-heater of the kind described, a water-reservoir situate at the bottom of the apparatus, an outlet from said reservoir provided with two passages of differential areas situate one above the other, substantially as described and illustrated. (5.) In a gas water-heater, a cylindrical casing having a reservoir of water in the bottom, a vertically guided float provided with a plug adapted to control the outlet of the gas-supply pipe, and a water-outlet from said reservoir, as and for the purposes set forth. (6.) In a gas water-heater, a cylindrical casing having a reservoir of water in the bottom, a vertically guided float provided with a plug adapted to control the outlet of the gas-supply pipe, and a water-outlet from said reservoir provided with a main passage and also with another restricted passage below said main passage, as and for the purposes set forth. (7.) In a gas water-heater, a floating valve supported in a reservoir of water whose level is regulated by the water-supply in the bottom of the casing of the heater, and adapted to control the supply of gas to the burner, in combination with an outlet or overflow to said reservoir provided with two separate passages, the upper one being of greater area than the lower one, substantially as described. (8.) In a gas water-heater, a float situate in a water-reservoir and provided with a sleeve surrounding the gas-supply pipe, a cap on the top of said float having an outlet in the upper end and a partition or diaphragm near the bottom provided with comparatively large openings and with a central downwardly extending plug formed with a restricted vertical passage, and adapted to be normally seated in the open end of said gas-supply pipe, a burner above said cap, and an outlet to said reservoir, substantially as and for the purpose set forth. (9.) In a gas water-heater, a gas-supply pipe extending upwardly through the bottom of the casing thereof and provided with a tap within the latter, said casing being provided with a hinged door extending the whole or a portion of its side, in combination with a float supported in a reservoir of water in the bottom of said casing, and provided with a cap having outlets, and a plug formed with a restricted outlet-passage and adapted to fit the open end of the gas-supply pipe, and an outlet or overflow to said reservoir of water having passages of differential area situate at different levels, all substantially as and for the purposes set forth. (10.) In a gas water-heater, means for automatically regulating the supply of gas according to the actual supply of water, substantially as and for the purpose specified.

No. 21146.—15th May, 1906.—GEORGE EVERARD CHURCHES, of Te Awamutu, New Zealand, Dairy-farmer. A cleaner for flexible tubes, the same being specially adapted for cleaning the rubber tubes used with milking-machines.*

Extract from Specification.—This invention relates to a construction of cleaner for flexible tubes, such as those made of indiarubber, and employed in connection with milking machines or appliances. Hitherto it has been customary to clean these tubes with brushes that are drawn through them, but such means do not prove to be effective, insomuch that the milk has a peculiar action upon the rubber, and tends to enter into combination therewith so as to coat the inside of the tubes with a coating that cannot be properly removed
