Claims.—(1.) In machines for “chipping” potatoes and the like, a base plate formed with a sliding top surface, a knife-frame resting upon and adapted to be reciprocated upon such sliding surface, a horizontal knife extending transversely across the top of the knife-frame, and a number of vertical knives depending at intervals from beneath the horizontal knife, in combination with means whereby the knife-frame and knives may be reciprocated and the material to be chipped fed into the machine so as to come into contact with the knives, as specified. (2.) A base plate formed with a sliding top surface, a cover hinged to the base plate and provided with a bottomless feed-hopper attached thereto, in combination with a knife-frame fitting between the cover and the sliding surface of the base plate and provided with means whereby it may be reciprocated, a horizontal knife extending across the top of the knife-frame with vertical knives depending at intervals therefrom, and an anvil-block provided with slots or grooves into which the knife-edges are adapted to fit, as and for the purposes set forth. (3.) The general arrangement, construction, and combination of parts in our improved machine for “chipping” potatoes and the like, as described and explained, as illustrated in the drawings, and for the several purposes set forth.

(3.) In an apparatus for printing in gold, silver, or other powders in the manner referred to, a horizontal bed, a work-table adapted to be reciprocated on the said bed, a vertically adjustable printing-block above the latter, an oil-roller, a powder-roller, and a powder-supply roller suspended from the said block, a slotted bracket on each side of the printing-block, a slide in each of the said brackets adapted to be reciprocated therein, bearings carried by the said slides in which the said oil and powder rollers are mounted adjacently, and a connection between the said slides and work-table for horizontally reciprocating the said rollers jointly, all combined substantially as and in the manner set forth. (4.) In an apparatus for printing in gold, silver, or other powders in the manner referred to, a horizontal bed, a work-table adapted to be reciprocated on the said bed, a vertically adjustable printing-block above the latter, an oil-roller, a powder-roller, and a powder-supply roller suspended from the said block, a slotted bracket on each side of the printing-block, a slide in each of the said brackets adapted to be reciprocated therein, bearings carried by the said slides in which the said oil-roller and powder-roller are mounted, and rails on the sides of the said block, the shaft-ends of the said oil-roller extending across the same, and inclines at the front end of the said rails adapted to guide the said shaft-ends underneath the said rails on the forward travel of the work-table, all combined substantially as and for the purpose set forth.

No. 15417.—18th September, 1902.—ERNEST SMITH BALDWIN and HENRIE HAMPTON RAYWARD, doing business under the name and style of Baldwin and Rayward, of National Chambers, Grey Street, Wellington, New Zealand, Patent Agents (nominees of George Edward Ridgway, of Brentwood, Ashley, Chester, England, Engineer). Improvements in apparatus for spreading liquids over given areas, primarily applicable for distributing sewage on to filter-beds.

Claims.—(1.) The improved apparatus for spreading sewage or other liquids over filter-beds, consisting of open troughs and means for imparting rotary motion to the said troughs, said means being adapted to be operated by the flow of the sewage itself, as and for the purpose described. (2.) The improved apparatus for spreading sewage over given areas, consisting of open troughs adapted to be moved rotarily, a supply-pipe, blades and openings between the supply-pipe and troughs whereby the troughs are caused to rotate upon the flow of sewage, substantially as described. (3.) The improved apparatus for spreading sewage over given areas, consisting of open troughs adapted to be moved rotarily, a supply-pipe having tangential openings e and blades f, blades g mounted at the inner ends of the troughs whereby the troughs are caused to turn upon the flow of sewage, in combination with the regulating plate u, substantially as described. (4.) The improved apparatus for spreading sewage over given areas, consisting of a pillar, open troughs radially arranged about the pillar and suspended therefrom, a supply-main opening to the axis of the troughs, vanes and openings between the supply-main and the radially arranged troughs whereby on the flow of sewage through the main the troughs will be caused to revolve, as and for the purpose set forth. (5.) In apparatus having troughs for spreading sewage or other fluids over filter-beds or other given areas, the combination with said troughs of an adjustable plate as u for regulating the outflow, substantially as described. (6.) The improved apparatus for spreading sewage or other fluids over filter-beds or other given areas, consisting of radial troughs as j that are supported by a central pillar as l and caused to rotate by the fluid from a central feed acting on tangential blades as g, in combination with blades as f, and with a plate u affixed to the troughs for regulating the outflow therefrom, all substantially as described.

No. 15418.—18th September, 1902.—ERNEST SMITH BALDWIN and HENRIE HAMPTON RAYWARD, doing business under the name and style of Baldwin and Rayward, of National Chambers, Grey Street, Wellington, New Zealand, Patent Agents (nominees of George Edward Ridgway, of Brentwood, Ashley, Chester, England, Engineer). An improved self-flushing time-valve appliance to sewage-distribution and other like purposes.

Claim.—The improved self-flushing time valve applicable to sewage-distribution and other like purposes, consisting principally of a door or flap, hinged at the top and closing downwards, acting against a seating fixed in the distributing-channel so that the pressure of the accumulating fluid keeps the valve closed, an opening or openings being made through or above the said valve at such a height that when the level of the accumulated fluid rises to a given height it flows through the said opening or openings into a chamber attached to the valve until the weight of fluid in such chamber overcomes the pressure on the valve, opening the same and allowing the fluid to escape with a “flush,” substantially as described, and illustrated by the drawings.

(2.) In bushed shafting, in combination, a shaft A having the end or ends concentrically shouldered as A¹, and further shouldered with any other than a round concentric section as A³, with a bush B, B¹, fitting same so that it will be as part of the shaft A, taking the wear from same at the bearings, said bush B being further secured by pin C through B¹ and A³, all substantially as set forth, and as shown on the drawing.
