end turned to receive the end of the hinge, and a hole in the gate-post into which the short end of the said bolt enters, substantially as set forth. (3.) The combination of a gate-hinge constructed as described in claim 1 with a strengthening-piece consisting of an eye and stem adapted to fit upon the hinge, substantially as set forth.

No. 22092.—21st November, 1906.—EMIL DEISTER, of 1415 Webster Street, Fort Wayne, Allen, Indiana, United States of America, Mechanic. Ore-concentrators.

Claims.—(1.) An ore-concentrator comprising a reciprocating-table with riffles thereon arranged in groups, the riffles of some groups varying in height and distance apart relative to those of other groups, the groups of higher riffles being located nearest the head-board or feed-side of the table, while the riffles of least height are nearest the tailings-discharge side thereof, and each group of riffles being separated from the adjacent group by a high riffle which projects above those of the groups. (2.) An ore-concentrator of the kind referred to comprising the rhomboidal table with the riffles nearest the head-board projecting higher and spaced further apart than the riffles nearest the tailings-discharge side, and a shoal-board along that portion of the forward end of the table adjacent the head-board. (3.) The improved ore-concentrator having its parts constructed, arranged, and combined to operate substantially as described with reference to the drawings.

No. 22093.—21st November, 1906.—HENRY HOWELL, 30 Chryssell Road, Brixton, London, England, Engineer. An improved incandescent-burner cluster for inverted lighting.

Claims.—(1.) In a burner for inverted incandescent lighting wherein a chamber to which the bent or inverted tubes are attached is mounted upon the head of the burner-tube, the arrangement within the said chamber of a cone or support carrying at its lower end a striking-plate against which the gas passing up through the burner-tube impinges before it passes to the bent tubes, in combination with a mantle-support carried independently of the tubes conveying the gas and air into the mantles and adapted to be adjusted relatively with the said tubes, substantially as and for the purposes described. (2.) In a burner for inverted incandescent lighting wherein a chamber to which the bent or inverted tubes are attached is mounted upon the head of the burner-tube, the arrangement within the said chamber of a cone or support carrying at its lower end a striking-plate against which the gas passing up through the burner-tube impinges before it passes to the bent tubes, substantially as described. (3.) A burner for inverted incandescent lighting wherein the mantle-supports are carried independently of the tubes conveying the gas and air into the mantles and adapted to be adjusted relatively with the said tubes, substantially as and for the purposes described. (4.) A burner for inverted incandescent lighting constructed and arranged substantially in the manner described, and illustrated in the drawing.

No. 22094.—21st November, 1906.—GEORGES SCHAULI, 175B Kentish Town Road, London, England, Electrical Chemical Expert Engineer. Improved electric cell.

Claims.—(1.) An electric cell comprising a negative-pole electrode composed of metallic plates and an intervening layer of porous liquid-absorbing material so arranged that the electrolyte comes into contact initially with one plate only, characterized thereby that the porous layer is in contact with the adjacent surfaces of both plates so that on the penetration of one by chemical action the electrolyte comes into electro-chemical action with the second plate at the portion of its surface adjacent to the place of penetration. (2.) A form of construction of electrode according to claim 1 in which each of the plates which are separated by the porous layer are metallically united to the attachment for the return lead to the cell of the electric circuit. (3.) A form of construction of electrode according to claim 1 in which the porous liquid-absorbing substance is impregnated with electrolytic reagents in a dry and inert condition. (4.) A form of construction of electrode for an electric cell in which the metallic plate with which the electrolyte comes in contact is a compound plate composed of a continuous fluid-tight plate and a perforated plate in metallic contact therewith.

No. 22118.—27th November, 1906.—FRIEDRICH LUDWIG BARTELT, of 3 Kensington Place, Brislington, Bristol, England, Soap and Chemical Manufacturer. Improvements in apparatus for washing linen.

Claims.—(1.) In apparatus for washing linen, a tank and structures placed therein comprising movable portions so arranged as to provide a zigzag channel for the linen, and means for giving to the movable portions movement in rotary paths in opposite directions whereby the linen is advanced and submitted to friction in the manner explained. (2.) The apparatus for washing linen comprising two structures made up of stationary and movable frames, and means for moving the movable portions in rotary paths in opposite directions, substantially as described. (3.) In combination with apparatus for washing linen comprising a tank and a structure forming a zigzag channel therein, feeding-rollers for the linen to prepare the same and to prevent choking or blocking of the channel by the linen, substantially as set forth.

(Specification, 4s.; drawing, 3s.)

No. 22121.—27th November, 1906.—ROBERT MORRIS LYONS, of Colac Bay, Wallace, Southland, New Zealand, Engine-driver. An improved shaft-coupling for marine engines and the like.

Claim.—A shaft-coupling comprising, in combination, a sleeve made in two parts, flanges upon the sleeve, bolts uniting the two parts of the sleeve together, keyways upon the ends of the shafts and upon the interior of the coupling, the said keyway in the sleeve being stopped at each end and a key deeper at each end than at its middle part, substantially as set forth.

(Specification, 1s. 6d.; drawing, 1s.)

No. 22126.—29th November, 1906.—RICHARD DIETZ, of 52 Barrett Street, Albert Park, Victoria, Australia, Marine Engineer; EDWARD KRIEGER, of Adelaide, South Australia, Engineer; and CHARLES ERNEST BARRY HART, of Elm Grove, St. Kilda, Victoria aforesaid, Business Manager. Improvements in and connected with seat-supports for bicycles and other vehicles, applicable also for handle-bars, crutches, and other purposes.

Extract from Specification.—The invention consists essentially in providing a support furnished at or near its upper end with an air-inlet valve, said support fitting within a cylindrical tube which forms an air or receiving chamber and is so arranged that when air is pumped into the support the latter acts as a piston or plunger within the said chamber and the seat of the vehicle rests on an air-cushion, by which means road riding or driving may be enjoyed more thoroughly than when the seats are supported on metallic springs in the ordinary manner. Moreover, improved retaining-means are provided by which the support can have only an up-and-down action, and when in operation it cannot rotate nor lift out of the cylindrical tube or receiving-chamber when raised to its highest position by the compressed air unless so required. With seat-supports or pillars of this description the main difficulty to be obviated is the escape of air, and our invention comprises a number of improvements whereby any leakage of air is effectually checked and the supports or pillars when once inflated will remain tight for a considerable time.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
