No. 24484.—4th June, 1908.—PITTLER UNIVERSAL ROTARY MACHINE SYNDICATE, LIMITED, of Norwich House, Southampton Street, High Holborn, London, England, Manufacturers (assignees of Julius Wilhelm von Pittler, of 6–7 Schiffbauerdamm, Berlin, Germany, Mechanical Engineer). Improvements in rotary engines, pumps, and similar mechanism.

———

Claims.—(1.) A rotary engine, pump, or the like mechanism in which slides having ports or openings therein are by axial or radial guide cams on the casing moved axially or radially in grooves in a carrier secured to the driving-shaft, whereby at one part of its revolution the openings in the slides pass over fluid-tight segmental pieces on the casing inserted in annular concentric grooves formed on one or both end surfaces of the carrier, and in the other part of its revolution the solid portions of the slides are moved to close the said grooves and form working chambers, substantially as described. (2.) A rotary engine, pump, or the like mechanism in which a carrier secured to the driving-shaft has a plurality of annular concentric grooves on one or both of its end surfaces and radial grooves crossing the annular ones, end casings having axial segmental pieces inserted fluid-tight in the annular concentric grooves to bound working chambers of the same cross section throughout the said grooves, and slides having ports or openings therein guided to move radially to pass the said segmental pieces at one part of a revolution and by their solid portions to close the said annular concentric grooves at the other part of their revolution, substantially as described. (3.) The modification of the mechanism claimed in the preceding claims whereby the pressure fluid is caused to act constantly upon the slides to keep them in contact with a cam surface at the outer end of the slides, substantially as described. (4.) The modification of the mechanism claimed in claims 1 and 2 whereby a space between the casing and carrier is caused to act as a chamber for the pressure fluid to exert pressure on the ends of the slides to counteract centrifugal force, substantially as described.

———

Claims.—(1.) An improved vehicle-wheel specially adapted to receive an auxiliary or spare rim, such wheel having an extra flange fixed to the metal rim or wooden felloe, substantially as set forth. (2.) An improved vehicle-wheel as above claimed, in which the extra flange is carried by a ring of shape suitable to fit the rim or felloe, substantially as set forth. (3.) An improved vehicle-wheel as above claimed in which the extra flange is located behind the plane of the outer face of the metal rim. (4.) A modification of the improved wheel above claimed, in which the extra flange is made in separate parts or sections, each part or section being carried by a ring section or fixing plate, substantially as set forth. (5.) The improved wheel claimed in claim 4, in which the extra flange is in the form of hooks, substantially as set forth and illustrated in Figs. 7 and 9. (6.) The improved wheel claimed in claim 4, in which the extra flange is in the form of loops, substantially as set forth and illustrated in Figs. 10 and 12.

No. 24506.—9th June, 1908.—IVOR BEVAN, of 92 Cannon Street, London, E.C., England, Merchant, and FREDERIC ANDERSON, of Freya, near Johannesburg, Transvaal, Engineer. Improvements in straightway valves.

———

Claims.—(1.) In a straightway valve the use of an ordinary tee as the valve body or casing, substantially as described. (2.) In a straightway valve the combination with an ordinary tee which serves as the valve body or casing, of a piece or casting, removably positioned, therein having a passage therethrough and constructed to form the valve-seat, substantially as described. (3.) A straightway valve as claimed in claim 2, in which the piece or casting is constructed with grooves for the reception of packing to make a fluid-tight joint between it and the tee, substantially as described.

[NOTE.—Here follow three other claims.]

No. 24513.—11th June, 1908.—FREDERICK LYMAN ALLEY, of 83 Clarence Street, Sydney, New South Wales, Australia, Engineer. Improvements in beating-machines for finishing boots and shoes.

———

Extract from Specification.—According to my invention I provide a guide which takes in the crease between the upper and the sole, or acts as a rest or guide in beating up boots and shoes after lasting and before the sole is laid. The said guide may be fixed, but preferably I have it mounted, so that the action of a spring keeps it in contact with the work and permits it to readily follow the contour of the boot or shoe. Adjacent to and preferably vertical with said guide is a sliding hammer, suitably mounted so that a reciprocating motion is imparted to it. On each side of the hammer is an adjustable guide or roll, which is also preferably provided with a spring. The said guides or rolls, in addition to forming rests for the boot, also have a smoothing-out effect, but primarily their object is to allow the hammer to retract from the boot after delivering a blow.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 24514.—11th June, 1908.—COLIN MATHESON BROWNE, of 43 Leopold Street, South Yarra, Victoria, Australia, Gentleman, and WALTER JOHN JAMES, of 55 Park Road, Middle Park, Victoria, aforesaid, Gentleman. An improved method of manufacturing boots, shoes, and the like from the skins of animals.

———

Extract from Specification.—The skin is removed from the animal or limb thereof by peeling it off so that the portion removed is practically tubular. This is cut to the desired length, and tied at one end after the manner of a ligature. It is then pulled tightly over the last or other molding-piece and tied or fastened at its other open end, so as to retain it in position. The last or mould, with the skin stretched tightly over it, is then immersed or subjected to treatment in a solution of alum, permanganate of potash or other astringent preservative or tanning substance, which tends to contract the skin tightly on the last or mould. After this it is removed and placed in the sun or any warm place and allowed to dry. When dry the skin is cut and the last or mould removed, when the ragged parts of the skin may be trimmed off and the edges braided or finished in any desired manner.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

———

Claims.—(1.) The improved saw-set, formed of a block of metal having an inclined slot adapted to receive a saw-tooth, extending upwards from its bottom edge, and an extension-piece extending longitudinally downward from one edge of the slot, substantially as specified. (2.) The improved saw-set as described in claim 1, in combination with a number of gauge-blocks of different lengths, each one of which is adapted to be secured in the top end of the slot, substantially as specified.

[NOTE.—Here follow six other claims.]
