No. 16799.—10th August, 1903.—CHARLES HENRY LOWE, of Violet Street, Eden Terrace, Auckland, New Zealand, Blacksmith. A complex lever for shoeing horses.*

Extract from Specification.—I use and employ the complex lever made and described — that is to say, where the curved arm c is adjusted, and set by the set-screw d, that while holding the head of the nail in position with the balance-plate e on the top bars the curved arm c on the sliding bar, by hand-pressure of the two lever-bars No.1 and 2 together, is brought to bear upon the cut ends of the nails protruding out on the face on the foot, its serrated teeth firmly clinching with ease each nail without any jar to the foot and in much less time than is now occupied.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 17058.—2nd October, 1903.—DAVID DUNN, of Oamaru, Otago, New Zealand, Mechanical Engineer. An improved wheel-jack.

Claims.—(1.) The general design and combination of the standard and lever, doing away with unnecessary parts, thus saving material and labour in its manufacture. (2.) The link C and its shape, the position of the hole and notch in the lever, causing it to lock when the wheel is raised, as in the position Fig. 5. (1.) The link C and its shape. (2.) The position of the hole in the lever B in relation to the notch F when connected to standard A by the link C.

No. 17390.—18th December, 1903.—ANDREW HARDIE McCULLOCH, of 118, Pitt Street, Sydney, New South Wales, Solicitor of the Supreme Court. The prevention of the escape of the volatile from the fixed carbon in the coal when burning.

Description.—Grind the coal fine, add to it 5 per cent. of burnt lime, then spread it on a clean floor and damp it with water having in it as much burnt lime as it will take up, and use care that it shall not be wet, but only damped so that the coal on being squeezed in the hand will remain as a ball, and after it has been exposed to the air in a dry place for about twelve hours press it in a brick or other press as severely as it can be, and place it to become dry, after which it will be ready to be used. I am aware that the combination of lime and coal as a fuel is not new, and I wish it to be understood that I do not claim such combination broadly.
[NOTE.—The above description is inserted in place of the claims.]

No. 17457.—12th January, 1904.—ALEXANDER HARRISON BROWNLEY, Jeweller, and ISAAC SAMUEL FLETCHER, Master Mariner, both of Onehunga, Auckland, New Zealand. New and improved serviette-holder.

Extract from Specification.—The device comprises an attaching-clasp 1 and a holding-clasp 2, connected together by a universal joint, the clasp 1 being for the purpose of attaching the device to a person or thing, and the clasp 2 to hold the article desired—for instance, a napkin or towel. The attaching-clasp comprises jaws 3 and 4, each provided with ears 5 and 6 respectively at opposite sides, through which a pivot-pin 7 passes, and for the purpose of holding said jaws normally closed to clasp an article between them a coil spring 8 is mounted on said pin, one end of which engages one of the jaws and the other end the other jaw. The holding-clasp comprises spring jaws 9 and 10, formed of one piece of metal bent upon itself and cut away at 10 to form spaced ears 11, between which a plate 12 on the inner end of the pivot-pin 7 projects, and is pivotally supported therein on a pin 14 passing through the ears 11 and through a hole in said plate, thereby forming a universal-joint connection between the two clasps so that they may be turned at different angles with relation to each other as may be required, and for the purpose of closing the clasp positively a lever 15 having a downwardly projecting nose 15a is pivotally and reciprocally supported in ears 16 on the lower jaw 10 of the clasp by headed journals 18 projecting laterally from opposite sides of the lever into engagement with the keyhole-slots 19 in said ears 16, the keyhole-slots being for the purpose of allowing the insertion of the headed journals and to allow rotary and reciprocatory movement of the lever 15, and the heads on said journals to prevent them from slipping out of the slots.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

(2.) In steam-boilers, the combination of a heating coil or coils in bottom of boiler with a connection to steam-space of boiler and an automatic trap for condensed water, together with pump or pumps automatically controlled for returning the condensed water to boiler. (3.) In steam-boilers, the combination of a heating coil or coils in bottom of boiler with a connection to steam-space of boiler and an automatic trap for condensed water, together with pump or pumps automatically controlled for returning condensed water to boiler through a chest with a coil for heating the feed-water.

The process of vulcanising and solidifying timber consisting in first impregnating it with sugar-syrup or liquor containing sugar, and subsequently artificially heating it and solidifying the sugar, substantially as described. (3.) The process of vulcanising and solidifying timber consisting in boiling the timber in a solution of syrup of sugar, or sugar-liquor, then heating such timber saturated with the syrup or liquor by hot dry air at temperatures such as specified, and driving off the moisture and solidifying the sugar therein, as set forth.
