No. 17627.—7th March, 1904.—JAMES PALMER CAMPBELL, of 15, Featherston Street, Wellington, New Zealand, Solicitor (nominee of George Westinghouse, of Westinghouse Building, Pittsburg, Pennsylvania, United States of America, Manufacturer). Improvements in fluid-pressure turbines.

Claims.—(1.) A vertical fluid-pressure turbine so constructed that the propelling fluid enters at or near the bottom and exhausts at the top of the turbine, and that the shaft-bearing is substantially relieved from the weight of the moving parts by upward fluid pressure acting within a balancing-chamber upon the rotary member, said pressure being automatically regulated in accordance with the conditions of exhaust by a relief-valve operated by the upward movement of the rotary parts when the pressure in the balancing-chamber is excessive. (2.) The modification of the invention in which the pressure in the balancing-chamber is utilised to control a pressure-regulating valve, whereby a pressure of propelling fluid is maintained within an auxiliary balancing-chamber, in restricted communication with the first-named balancing-chamber, which pressure does not exceed by more than a predetermined amount the variable pressure of supporting fluid within the first balancing-chamber, substantially as described. (3.) In a vertical turbine of the kind described, means for adjusting the relief-valve seating independently of the adjustment of the rotating parts, for the purpose specified. (4.) A vertical fluid-pressure turbine of the kind described in which means are provided for conducting the leakage of propelling fluid to a point where its energy can be utilised, substantially as described. (5.) Means for supporting the rotating parts of a vertical fluid-pressure turbine under all conditions of exhaust, arranged and operating as described with reference to the drawings. (6.) The construction of vertical fluid-pressure turbine shown in the drawings.

No. 17628.—7th March, 1904.—JAMES PALMER CAMPBELL, of 15, Featherston Street, Wellington, New Zealand, Solicitor (nominee of George Westinghouse, of Westinghouse Building, Pittsburg, Pennsylvania, United States of America, Manufacturer). Improvements in fluid-pressure turbines.

Claims.—(1.) For a fluid-pressure turbine, an impulse or impact wheel provided with fluid-receiving passages which extend inwardly and forwardly and thence outwardly and rearwardly to one or to both side surfaces of the wheel. (2.) The modification in which the fluid-receiving passages extend forwardly at a gradually increasing depth for portions of their lengths, and thence outwardly and rearwardly with a gradually increasing area to one or both side surfaces of the wheel. (3.) A turbine-wheel constructed substantially as described and shown in Figs. 1 and 2, or in Fig. 4, of the drawings. (4.) A fluid-pressure turbine constructed substantially as described and shown in Figs. 3 and 5 of the drawings.
(Specification, 5s. 6d.; drawings, 2s.)

No. 17630.—8th March, 1904.—JAMES GRAY, of Dunedin, Otago, New Zealand, Agricultural-implement Maker and Importer. Improvements in the construction of seed-sowers.

Claims.—(1.) In seed-sowers, in combination, a hollow cylinder having grooves and rows of holes, a seed-case having an outlet near its bottom, horns upon the seed-case extending partially around the cylinder, and a removable annular band fitted into the cylinder to form a bottom for the said holes, substantially as and for the purposes set forth. (2.) In seed-sowers, an annular band fitted into the sowing cylinder, the said band forming a bottom for the holes in the cylinder, substantially as and for the purposes set forth. (3.) The combination and arrangement of parts comprising the improvements in seed-sowers, substantially as and for the purposes set forth, and illustrated upon the drawing.

No. 17633.—8th March, 1904.—CHARLOTTE FRANCES AMY SCHAEFER, ERNEST GEORGE SCHAEFER, and PHILIPP PAUL SCHAEFER, trading as “Schaefer and Company,” of Wellington, New Zealand, Merchants (assignees of Albert Lauermann, of Detmold, Germany, Manufacturer). An improved composition for the manufacture of stucco ornaments and the like.

Claim.—In the manufacture of stucco ornaments, the introduction of cotton wool into the pulpy composition of which the ornaments are made.
(Specification, 2s. 3d.)

No. 17643.—10th March, 1904.—SAMUEL WHITFIELD THACKERAY, of 118, Annandale Road, Greenwich, London, England, Patent Expert. An improved keyboard adapted for playing music at any absolute pitch, and an improved system of musical notation specially adapted for use therewith, and also adapted for other musical purposes.

Extract from Specification.—The Uniclef keyboard may be of any convenient compass, and consists of a series of keys, which preferably may be of uniform size, shape, and colour, arranged at a uniform level, thus dispensing with the ordinary short raised black keys. Each key may consist of two sections, b, b', superposed on each other. Figs. 8 and 11 show transverse sections of this key taken on the line a— in those figures. The lower portions of the keys are fitted to the instrument in the ordinary manner, and are each furnished on its upper face with slotted feathers c, whereon the corresponding upper portion is fitted and secured by pins inserted therein transversely, so that it is free to slide either backward or forward by operating a transposing-bar d, which is fitted across the action of the instrument at the back part of the keyboard. By this means that part of any key which is operated on by the fingers may be made to occupy either a front position or a rear position. Such bar has a series of teeth e formed on its lower edge which engage with catches f fitted to the rear ends of the upper sections. These teeth are spaced out so as to form a series of octaves of any given scale, the number of octaves being governed by the compass of the keyboard. Or, instead of making each key in two parts, it may be made integral—that is, in one piece, and not in upper and lower sections as above described. In this modification slots are substituted in place of the circular holes with which ordinary keys are provided on their undersides for the supporting pegs to take position in. The said slots must be of sufficient length to admit of the keys being slidden the desired distance forward and backward, preferably about two inches. . . . The second part of my invention relates to the representation of music, and consists in the improved staff and representations of notes and their arrangement described and illustrated in the drawings, and specially adapted for use with the Uniclef keyboard, and for other purposes. By these improvements leger lines, clefs, key signatures of sharps and flats, and the various chromatic and enharmonic signs, together with the different characters and devices for indicating time values of notes hitherto in use, are entirely dispensed with; and by the combined use of the Uniclef keyboard, the Uniclef staff, and the Uniclef musical notation, the ancient principle of a movable doh system of notation as now employed in the tonic sol-fa method for singing merely is rendered applicable to instrumental as well as to vocal music. The staff which I prefer to use may be obtained in this manner: The lines of the staff are a mere representation in miniature of some of the equidistant division lines between the keys on my Uniclef keyboard, or between the rear portions of the keys on an ordinary keyboard. These division lines are supposed to be transferred in miniature to the music-sheet, and then, if necessary, prolonged across the whole width of the paper. Horizontal lines specially distinctive are used to mark off spaces of the staff which represent intervals of an octave, corresponding to the space occupied by twelve keys on the keyboard. Thick black lines are preferable for the purpose.

No. 17646.—10th March, 1904.—JOSEPH THOMAS PRINCE, of Papatoitoi, Auckland, New Zealand, Blacksmith. Improvements in or relating to whiffletrees.

Extract from Specification.—According to this invention a whiffletree has a coupling or bracket at each end provided with a spike which enters a hole in the whiffletree, a shoulder butting against the end of the whiffletree, and an eyelet-hole formed in a bracket which extends along the whiffletree. The links to which the traces are attached pass through the eyelet-holes and loosely around the whiffletree. The centre bracket has an eyelet-hole for the usual drawpin and spikes for entering the whiffletree. The bracket is secured by bolts.

No. 17648.—11th March, 1904.—AXEL WILLIAM TOPFER, of Reefton, New Zealand, Miner. Improved means for releasing runaway horses from vehicles.

Extract from Specification.—This invention provides means for releasing from a vehicle horses which have become un-
