No. 16278.—28th April, 1903.—EDWARD VERDON DIXON, of Opotiki, Auckland, New Zealand, Mechanical Engineer. An improved screw propeller.*

[NOTE.—The title in this case has been altered. See list of provisional specifications, Gazette No. 37, of the 14th May, 1903.]

Claims.—(1.) A ship’s propeller formed with a blade helically arranged upon a boss, and of spirally increasing radius from the outer end to the base, and ending in a radial edge extending inwards to the boss, such blade being formed with a widened portion at a point in its helical length of equal width to the width of the blade at its base end and with a radial edge extending inwards from such widened portion diametrically in a line with the radial edge at the base end of the blade, substantially as specified. (2.) A ship’s propeller formed with a pair of blades each helically arranged upon a boss, and of spirally increasing radius from the outer end to the base, and each ending in a radial edge extending inwards to the boss in the same diametrical line, each of such blades being formed with a widened portion in its helical length of equal width to the width of the blade at its base end and with a radial edge extending inwards from such widened portion in the same diametrical line but at right angles to the radial edges on the base ends of the blades, substantially as specified.

No. 16288.—30th April, 1903.—ALFRED MOUSELL SPRANGER WATTS, of College Street, Palmerston North, New Zealand, Inventor. Improved means for attaching draw-off taps to drums and the like.*

Claims.—(1.) In means for attaching draw-off taps to drums and the like, a tap formed with a flange and with a pointed barrel adapted to pierce the side of the drum, and a flange upon the barrel, near the top flange, adapted to be screwed into the drum so as to grip the edges of the pierced hole between the adjacent faces of the two flanges, as specified. (2.) In means for attaching draw-off taps to drums and the like, a tap-barrel formed with pointed ends and with a radial longitudinally tapering knife upon its outer periphery, and a circular flange-plate upon the barrel, broken away for a short distance in its circumference, to one edge of which the radial knife is attached by means of a curved portion, as specified. (3.) A tap formed with a flange upon its end, in combination with a barrel one end of which is adapted to be secured to the flanged end of the tap, and the other end of which is formed with pointed ends, a flange-plate secured upon the barrel near the flanged end of the tap and extending nearly round the circumference thereof, a sharpened edge upon one end of the flange-plate, and a radial longitudinally tapering knife upon the outer periphery of the barrel attached to the other end of the flange-plate by means of a curved portion, all as and for the several purposes set forth. (4.) The general arrangement, construction, and combination of parts in my improved means for attaching draw-off taps to drums and the like, as described and explained, as illustrated in the drawings, and for the several purposes set forth.
