No. 22379.—31st January, 1907.—JENS WORM JENSEN, of Willis Street, Palmerston North, New Zealand, Settler. A device for holding the tails of cows while being milked.

Claims.—(1.) An improved mechanism for holding the tails of cows while being milked, such mechanism consisting of a springy metal clasp or clip, as set forth. (2.) In mechanism for holding the tails of cows comprising a springy metal clasp or clip, one end of the clasp or clip to fasten to the milker’s trouser-leg and the other to the cow’s tail, as set forth.

No. 22388.—5th February, 1907.—ALFRED GEORGE JACKSON, of Ann Street, Brisbane, Queensland, Australia, Electrician. Improvements in mechanism for electric clocks and other purposes.

Claims.—(1.) Improved mechanism for electric clocks and other purposes, comprising a gravity propelling-lever normally supported by a spring catch, a releasing-wheel operated directly by a pawl on the clock-pendulum, said wheel constructed to direct the said pawl periodically against the spring catch and release the gravity lever, a wheel on said gravity lever adapted to come in contact with the pendulum on the fall of the lever, an electric circuit through a magnet to throw up the gravity lever to its initial position, and a dial or dials electrically propelled and operated by the said pendulum, substantially as set forth. (2.) In an electric-clock mechanism of the kind set forth, the arrangement of parts for producing the electric circuit through the gravity lever, dial-circuit, magnets, and armature so that the duration of contact at each impulse will be decided by the self-induction, and the eventual stoppage of the clock will be in open circuit, substantially as described. (3.) In an electric-clock mechanism of the kind set forth, the arrangement of the pendulum A, the gravity arm B, and the armature D so that in the event of the electrical energy developed being insufficient to raise the said gravity arm sooner, the return stroke of the pendulum will assist the action of the current and the increased duration of contact will automatically indicate the impending failure of current, substantially as described. (4.) In electrical clock mechanism of the type set forth, the combination with an electrically actuated dial-circuit of the pendulum A, the adjustable wheel R, the pawl F, the gravity lever B with block G, the escape-wheel E, the check E², the arm H with support C, the magnets M, the armature D, substantially as and for the purpose described, and shown in the drawing. (5.) In combination with an electric-clock mechanism of the type set forth, the split or adjustable pawl F and adjustable wheel R on lever B, substantially as and for the purposes described, and illustrated in the drawing.

No. 22403.—6th February, 1907.—ALBERT RICHARD DIETZ, of 52 Barrett Street, Albert Park, Victoria, Australia, Marine Engineer; THOMAS RUFFIN RICKETTS, of Warragul, Victoria aforesaid, Seed-grower; and FREDERICK HENRY COOK, of Dandenong, Victoria aforesaid, Engineer. Improvements in and connected with rotary engines.

Extract from Specification.—An engine constructed according to our invention possesses the advantages of having most of the working-parts arranged outside the cylinder, whereby they may be readily adjusted or replaced with ease and convenience, thus obviating the disadvantage of dismounting the engine, as is the case with most rotary engines when adjustment or repair is required. In this invention there is provided a cylindrical casing forming a chamber of suitable diameter and width, provided with—at ordinarily its top portion—a cylindrical steam-chest furnished with a slide-valve of the piston type, and so constructed that there is no back pressure of steam on the same, besides possessing other features described. The main piston of our engine, consisting of a cylindrical drum or disc secured to the main shaft and designed to revolve within the cylinder or steam-chamber, is of suitable dimensions, furnished with one or more piston-blocks—one for single expansion and three for a triple-expansion engine. The piston block or blocks, having the same width as the piston, are of such height as to fill the space between the outside periphery of the piston and the inside periphery of the cylinder, and are preferably constructed integral with the piston.

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

No. 22418.—13th February, 1907.—WILLIAM McEACHERN, of Rosewood, New South Wales, Australia, Civil Engineer. Improvements in and connected with bottle-attachments and aerated-liquid delivering.

Claims.—(1.) A perforated block having means for the opening of (and a passage for withdrawal of liquid from) an inverted internally stopped bottle, in combination with a projecting screw for fastening the block and adjusting its position relatively to a support. (2.) A perforated block having means for the opening of (and a passage for withdrawal of liquid from) an inverted internally stopped bottle, in combination with a projecting screw for fastening the block and adjusting its position relatively to a support, the screw being located non-centrally so as not to be under the block-passage. (3.) A perforated block of the class described having in its base a screw-threaded hole for the adjustment therein to a predetermined depth of one end of a screw, the other end of which will project from the block, for the purposes described. (4.) In a device of the class indicated, a combined table-clamp, standard, adjustable bottle-clamp, perforated block, and bottle-pressure means, as set forth. (5.) In a device of the class indicated having a standard and an arm pivoted thereto for pressing down a bottle, a pressure-member projecting from the said arm and adjustable by screwing, substantially as described. (6.) In a device of the class indicated, a block having a nozzle to support an unseated ball within the bottle-neck, and a passage having its upper or vertical part of less diameter than its lower part, and an exit-pipe having its passage of greater diameter than the said vertical part of the block-passage.

No. 22420.—13th February, 1907.—CHARLES JAMES WALKER, of “Cloverfield,” No. 238 McKean Street, North Fitzroy, near Melbourne, Victoria, Australia, Boot-manufacturer. Improved manufacture of boots and shoes.

Claims.—(1.) In the manufacture of boots and shoes, the employment of a “rand” or narrow strip of leather formed with a channel along its inside edge, the inner selvage of said channel being tingled near the edge of the last, and the other selvage turned upwardly for the purpose of sewing the upper thereto, substantially as set forth. (2.) In the manufacture of boots and shoes, the employment of a “rand” or narrow strip of leather formed with a channel along its inside edge, the inner selvage of said channel being tingled near the edge of the last, and the other selvage turned upwardly, and a stay-piece adapted to be placed within the “rand” and sewn in conjunction with the upper to said upturned selvage of the “rand,” for the purpose set forth. (3.) In the manufacture of boots and shoes, the employment of a “rand” or narrow strip of leather formed with a channel along both edges, and secured to the last by tingles passed through the inner selvage of the inside channel, the outer selvages of each channelled edge of the “rand” being turned upwardly for the purpose of stitching the welt-strip and the upper thereto, substantially as set forth. (4.) In the manufacture of boots and shoes, the employment of a “rand” or narrow strip of channelled leather to which the upper is stitched and tacked to the last, and following the contour thereof, said “rand” being made up of two separate pieces, the meeting ends of which are cut in an opposite oblique direction, substantially as set forth.
