A tap provided with a two-way cock or plug so disposed and arranged that when the cock or plug is turned in one direction communication shall be established between the liquid-reservoir and a measuring-chamber, and when turned in another direction communication shall be established between the measuring-chamber and the exit-passage of the tap, in combination with a graduated measuring-chamber such as C that is provided with an axial tube which may slide freely through a gland in the cover of the measuring-chamber or be permanently fixed in any desired position, as and for the several purposes specified. (4.) The general arrangement, construction, and combination of parts in our improved measuring-tap as described, as illustrated in the drawings, and for the several purposes specified.

No. 16056.—6th March, 1903.—JAMES McGRATH, of Peak Station, Onslow, Western Australia, Pastoralist. Thumb and guard attachment to sheep-shears.

Claims.—(1.) In sheep-shears, an attachment forming a combined thumb-rest and guard-plate as f, which is secured in a hinged or pivotal manner to a blade as b of the shear, substantially as and for the purposes set forth and explained, and as illustrated in the drawings. (2.) In sheep-shears, adjustment holes as c formed in the blade as b of the shear, whereby a plate attachment as f may be adjustably secured thereto so as to suit the requirement of the user, substantially as and for the purposes set forth and explained, and illustrated in the drawings. (3.) In sheep-shears, a hinged plate as f provided with a screw-pin as d and with a bracket as e, the whole secured to and in combination with a shears-blade, which latter is formed with adjustment holes as c, substantially as and for the purposes set forth and explained, and as illustrated in the drawings.

No. 16066.—9th March, 1903.—EDWARD WATERS, Jun., a member of the firm of Edward Waters and Son, of 414–418, Collins Street, Melbourne, Victoria, Patent Agents (nominee of the St. Louis Plate Glass Company Corporation of Missouri, and having a place of business at Valley Park, St. Louis, Missouri, United States of America—assignee of Daniel James Murnane, of Kirkwood, St. Louis aforesaid, Glass-manufacturer). Improvements in machinery for grinding and polishing glass.

Claims.—(1.) A machine for grinding and polishing glass wherein a revolving runner-frame carries blocks having grinding or polishing surfaces mounted therein, in such manner that they are loosely held so as to be free to bear by gravity upon the glass to be ground or polished, and are at the same time maintained by centrifugal action in substantial parallelism with the glass surface to be ground, substantially as described. (2.) In a grinding and polishing machine such as is referred to in the first claim, connecting the gravity blocks at their inner end in an automatically adjustable manner to the runner-frame so that such connection shall always lie practically in the same plane as and in a radial line with the centre of gravity of the block, in order by centrifugal action to insure the parallelism of the grinding-surface of the block with the glass surface, substantially as described. (3.) In a grinding and polishing machine of the kind referred to in the first and second claims, the modification whereby the gravity grinding-blocks are loose in the runner-frame and are held against the action of centrifugal force by abutment surfaces on the runner-frame, against which they bear in such manner as to be capable of moving up and down thereon, substantially as described. (4.) In a grinding and polishing machine of the kind referred to in the first claim, connecting the gravity grinding-blocks to a vertically movable runner-frame by means of adjustable suspension bolts, so arranged that when the frame is raised the blocks are suspended therefrom by means of the said bolts, while when it is lowered so that the blocks rest upon the glass to be ground they are not suspended by the bolts but are free to be acted upon by gravity, substantially as described. (5.) In a grinding and polishing machine, a revolving runner-frame consisting of a central hub with annular gutter for the reception of abrasive material, from which radial or tangential arms or ribs project that are connected together at their outer ends by an annular flange, the sector-shaped spaces between the ribs serving to contain correspondingly shaped loose grinding-blocks that are carried round by coming in contact therewith, substantially as described. (6.) In a revolving runner-frame such as is referred to in the fifth claim, the arrangement for raising and lowering the same in order to raise the grinding-blocks up from and to lower the same

on to the glass surface, consisting in suspending the central shaft thereof from a lever by which it can be raised and lowered and adjusted accurately in the required lowered position, the said shaft being connected by a feather and groove with a toothed wheel through which it receives rotary motion, substantially as described. (7.) The combination with a runner-frame having tangential arms or ribs, such as referred to in the fifth claim, of grinding-blocks having corresponding tangential sides so as to operate obliquely upon projections on the glass surface, substantially as described. (8.) In a machine for grinding or polishing glass, a revolving runner-frame suspended from a suitable raising and lowering device, and having radial or obliquely placed arms or ribs between which are loose sector-shaped grinding-blocks so connected to the runner-frame that while they can be raised and lowered thereby they are free to bear by gravity upon the glass surface when in the lowered position, substantially as described. (9.) In a machine for grinding or polishing glass, a revolving runner-frame having radial or obliquely placed arms or ribs between which are sector-shaped gravity grinding-blocks, the inner ends of which are connected to the hub of the runner-frame by pivoted links so arranged as to be automatically shiftable in the vertical direction both as regards their connection with the hub and as regards their connection with the grinding-blocks, substantially as and for the purposes described.

No. 16068.—9th March, 1903.—HENRY HARRAWAY, of Crawford Street, Dunedin, New Zealand, Miller and Grain Merchant. An improved grain drier and conditioner.

Claims.—(1.) In means for drying grain, an internally heated chamber provided with perforated sides and with an outer covering or shell composed of louvres or perforated material arranged so as to leave vertical spaces between the chamber and the shell, in combination with means whereby the grain may be delivered into the top ends of the spaces and collected at the bottom ends, and with means for conducting heat to the inside of the inner chamber, as specified. (2.) In means for drying grain, a chamber with perforated sides and with a perforated outer shell arranged so as to leave vertical spaces between the chamber and the shell, in combination with horizontal alternately inclined deflector plates placed one above the other within such spaces, as specified. (3.) In means for drying grain, a chamber with perforated sides and with a perforated outer shell arranged so as to leave vertical spaces between the chamber and the shell, in combination with a chamber or duct leading into the bottom of the chamber and provided with a number of apertures, such chamber or duct being in communication with a source of heat-supply, as specified. (4.) In means for drying grain, a chamber with perforated sides and with a perforated outer shell arranged so as to leave vertical spaces between the chamber and the shell, in combination with hoppers placed upon the top of the chamber with passages leading therefrom to the top of the spaces, a trough placed longitudinally beneath the bottom of the spaces, and an archimedian screw mounted longitudinally within the trough, as specified. (5.) The general arrangement, construction, and combination of parts in my improved means for drying and conditioning grain, as described and explained, as illustrated in the drawings, and for the several purposes set forth.

No. 16069.—9th March, 1903.—PETER ESKESEN, of Waihi, Auckland, New Zealand, Bootmaker. An improved boot.

Extract from Specification.—This invention relates to the manner of constructing the boot-uppers of lace-up boots, being devised for the purpose of dispensing with the front seam caused by the joint of the two pieces of which the upper is generally composed. The invention consists in forming the upper of one large piece, that is so shaped that when doubled over it shall form the whole of the upper with the exception of a small side or filling-in piece that is secured to it in order to complete the upper.
Claim.—Constructing the uppers of boots in the manner described and explained, as illustrated in the sheet of drawings, and for the purposes set forth.
