finger and ruler. A semicircle inscribed upon the plate is divided into degrees. Other semicircles inscribed upon the plate are divided as required to form letters of the alphabet having various characteristics. Thus, a vertical block letter or numeral, or a block letter or numeral sloping to the right or left, may be formed, and the instrument is provided with means whereby a letter may be made with a thick down-stroke and fine upstroke.

No. 21115.—31st August, 1905.—SAMUEL FREDERICK MUDGE, of Wilson Street, Albury, New South Wales, Australia, Auctioneer. An improved adjustable wheel-tire.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Australia.]

Claims.—(1.) An improved adjustable wheel-tire formed in one or more sections, enlarged ends on said section or sections, recesses formed in said ends, and tie or connecting pieces formed corresponding in shape to said recesses, in combination with a wheel having its rim formed corresponding to the tire sections. (2.) An improved adjustable wheel-tire formed in one or more sections, enlarged ends on said section or sections, circular recesses formed in said ends, and tie or connecting pieces formed with ends corresponding in shape to said recesses, in combination with a wheel having its rim formed in sections, substantially as described. (3.) In a wheel-tire of the kind described, formed of one or more sections, enlarged ends on said sections, recesses extending through said enlarged ends, a feather-edge flange on said section or sections of tire in combination with a tie or connecting piece, and fastening bolts or pins extending through the ends of the tie-pieces and through the enlarged ends of the tire section or sections, substantially as set forth. (4.) In a wheel-tire of the kind described, formed of one or more sections, enlarged ends on each section of the tire, circular recesses extending partly through said enlarged ends, a shoulder formed at the end of each circular recess, a hole extending through said shoulder, in combination with a tie or connecting-piece having circular ends thereon and lateral pins on said ends, substantially as described. (5.) In a wheel-tire of the kind described, formed of one or more sections, enlarged ends on said section or sections, recesses in said ends, and tie or connecting pieces corresponding in shape to said recesses, and with or without fastening-bolts, slots in the ends of said tie-pieces and in the enlarged ends of the tire sections, pins adapted to fit into said slots, in combination with a wheel having its rim formed corresponding to the tire sections, substantially as set forth.

No. 21116.—9th May, 1906.—JOHAN PETTER JOHANSSON, Enköping, Sweden, Managing Director of Enköpings Mekaniska Werkstads Aktiebolag, Enköping, Sweden. Improvements in centrifugal liquid-separators.

Extract from Specification.—This invention relates to an arrangement of the plates differing from those stated above, which renders the said distance pieces or projections superfluous, the spaces between the plates being thus open and free entirely along their whole surface. Owing to this fact the plates may be fixed to each other at their inner edges, as the open spaces are so accessible that the cleaning operation can be effected without the plates being further separated. By this arrangement the liner, as a whole, becomes a single firm body, which can easily be put into and taken out of the drum, and also can be more easily handled than liners composed of a plurality of small pieces. The said object is attained by the liner—that is, the whole set of plates—being made conical or convex at its top as well as at its bottom with the axis of the cone coinciding with the axis of the drum and by the drum being correspondingly shaped inside at the top and at the bottom, so that the liner is positively supported along its conical or convex surface by the drum. For that reason the latter is provided with a funnel-shaped bottom and with a cover or an inner cap, like a funnel turned upside down. As the said surfaces of the liner are the same at the top and bottom edges respectively of the plates, each plate has in this manner a positive support against the drum at the top edge as well as at the bottom edge along its whole length between the inner edge and the outer edge. Owing to this fact it is held in a reliable manner in its position, and prevented from bending during the rotation. For additional security such a special curved shape has been given to the plates that they form a large angle—that is, almost a right angle—to the radius of the drum for the greatest part of their length, so that the plates viewed from the top for the greatest part of their length with the edge will follow the top and bottom bearing surfaces of the drum mentioned above, almost parallel to the circumference of the drum, owing to which fact the plate is prevented from sliding outward along the said surfaces. At the same time the space—that is, the distance between the plates—will become great near the centre of the liner and small at the circumference of same, which is a great advantage, since the milk-layers then are thin where the centrifugal force is greatest, and the slow-running cream has to overcome less resistance or get better room near the centre, between the plates. If desired, the said bearing surfaces may be provided with notches with which the plates engage.

No. 21253.—30th May, 1906.—ROBERT ANDREWS and WILLIAM ORANGE MCFADDEN, both of Parnell, Auckland, New Zealand, Contractors, and DANIEL WHITBURN, of Auckland aforesaid, Carpenter. An improved means of fastening gratings in traps and cesspits or drainpipes.

Claims.—(1.) In the improved means for fastening gratings in traps and cesspits or drainpipes specified, the grating made with lugs as part thereof or secured thereto, the groove made in said grating with the bolt adjusted to work therein, fitted to engage recesses made in the trap and in cesspit and the said recesses for the purpose set forth, substantially as described and illustrated. (2.) In the improved means for fastening gratings in traps and cesspits or drainpipes specified, the holes made in the trap and in cesspit with hook fixed in one hole and angle-iron turnably fitted in other hole both to engage grating and in combination with said grating for the purpose set forth, substantially as described and illustrated.
