preserving wood, which consists in making an aqueous solution of aluminum sulphate, mixing with said solution a carbonate, impregnating the wood with the mixed solution, and subsequently evaporating the moisture from the wood. (5.) The described process of preserving wood, which consists in injecting a preserving fluid through the wood from one end thereof to the other in the direction of the grain of the wood, discharging the fluid from the opposite end of the wood until the specific gravity of the fluid being emitted is substantially equal to that of the fluid being injected, thereupon preventing the escape of the fluid from the wood at the discharge end thereof, and continuing the injection of the fluid until it is distributed radially from the centre through the substance of the wood and appears at the circumference thereof. (6.) The combination with an impregnating receptacle of means for opening and closing said receptacle, a gasket of resilient material within said receptacle arranged to seclude one end of a body of wood inserted therein, means to inlet and outlet fluid with respect to said receptacle, and means to control the pressure of fluid at the secluded end of said body, independently of the remainder thereof. (7.) The combination with an impregnating receptacle of means for opening and closing said receptacle, means within said receptacle arranged to seclude one end of a body of wood inserted therein, means to inlet and outlet fluid with respect to said receptacle, means to control the pressure of fluid at the secluded end of said body independently of the remainder thereof, rollers mounted to rotate in said receptacle, and means exterior to said receptacle arranged to actuate said rollers. (8.) The combination with an impregnating receptacle of means for opening and closing said receptacle consisting of removable lids secured to the opposite ends thereof, a gasket of resilient material within said receptacle supported by one lid thereof, means in the other of said lids arranged to adjustably thrust a body of wood within said receptacle against said gasket, a fluid-port for the space surrounding said body within said receptacle, means to control said port, a fluid-port for the space enclosed by said gasket, and means to control said port. (9.) The combination with an impregnating receptacle of an externally projecting chamber arranged at the end thereof, a circumferential inwardly facing seat arranged around the end of said receptacle, a sliding lid adapted to close against said seat and to be withdrawn into said chamber, means connected with said lid whereby it may be shifted to and from said chamber and said seat, means within said receptacle arranged to seclude one end of a body of wood inserted therein, and means to control the pressure of fluid at the secluded end of said body independently of the remainder thereof. (10.) The combination with an impregnating receptacle of an externally projecting chamber arranged at the end thereof, a circumferential inwardly facing seat arranged around the end of said receptacle, a sliding lid adapted to close against said seat and to be withdrawn into said chamber, means connected with said lid whereby it may be shifted to and from said chamber and said seat, means carried by said lid arranged to seclude the end of a body of wood inserted in said receptacle, a fluid-port opening through said lid in communication with the secluded end of said body, and means to control said port. (11.) The combination with an impregnating receptacle of a lid in removable relation therewith, a slide-bearing in said lid, a shaft supported by said receptacle and extending through said slide-bearing, a thrust-bar entered through said lid, and means to adjust said bar longitudinally through said lid.

No. 14522.—13th February, 1902.—FRANK WIGGINS, of Tacoma, Washington, United States of America, Gentleman. Improvements in self-tightening clutches for pulleys.

Claim.—In combination with a shaft and split pulley, one of the adjacent edges of the section of said pulley being recessed, the bottoms of the recesses being straight and inclined in relation to each other, the oppositely disposed keys curved on their inner toothed faces, and straight on their opposite faces, to correspond with the walls of said recesses, as set forth.

No. 14523.—13th February, 1902.—HERBERT BRYAN NEWTON, of 123, Main Street, Haverhill, Massachusetts, United States of America, Manufacturer (assignee of Arsene Hebert, of 100, Purchase Street, Boston, Massachusetts aforesaid, Machinist). Hand tacking-tool.

Claims.—(1.) A hand tacking-tool comprising a relatively fixed member, a reciprocating member having a tack-passage therethrough, a driver which is secured to said fixed member and is arranged in said passage, a latch which in its normal position permits the passage of a tack below said driver, but which is adapted to freely slide upwardly across said passage, and thereby prevent movement of the tack above the end of the driver. (2.) In a hand tacking-tool, a relatively fixed member, a reciprocating member having a tack-passage which extends to its lower end, a driver which is secured to said fixed member and arranged in said passage, a pivoted latch which is adapted to freely slide obliquely across said passage below the end of the driver when the reciprocating member is in its outermost position, a spring for swinging said latch across said passage at the lower end thereof, and a stop for said spring which prevents the latter from pressing said latch against the opposite wall of said passage. (3.) A hand tacking-tool comprising a relatively fixed member, a reciprocating member, one of said members having a hammer face, a relatively narrow projection on said reciprocating member which extends to one side of said face and has a tack-passage, and means for forcing the tacks separately out of said passage. (4.) A hand tacking-tool comprising a hammer 2, a block 4 which slides in said hammer and has a narrow projection 40 extending beyond the hammer’s face, and means for forcing the tacks separately from the end of said projection near its edge. (5.) In an automatic tacking-device, a slotted support as 27 upon which the tacks are delivered so that they hang by their heads, a feeder as 28 which engages the tacks below said support and separates and delivers them into the tack-passage.
