COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 17616.—4th March, 1904.—ALBERT OLIVER SMITH, of Feilding, New Zealand, Carpenter and Builder. An improved acetylene-gas generator.*

Claim.—A small tank tapered at the bottom with a sludgetap in it, a tube or carbide chamber at the top end with a revolving shelf to hold the carbide out of water while charging, and a water sealed pipe from generator to holder. (Specification, 2s.; drawing, 1s.)

No. 17625.—7th March, 1904.—RODOLPHE JEAN WILLIAM GRASSET, of 10, Railway Place, South Yarra, Victoria, Australia, Mechanical Engineer. An improved electrical hydro-pneumatic governor for marine engines.*

Claims.—(1.) In an electrically controlled hydro-pneumatic governor for marine engines, the adoption and use of an electric contact-breaker such as o, o, and clutches m, m, in conjunction with a solenoid such as v, whereby automatic and instantaneous control of the throttle or other equilibrium valve is secured, substantially as and for the purposes set forth and described, and illustrated by the drawing. (2.) In an electrically controlled hydro-pneumatic governor for marine engines, the combination of parts whereby a varying air-pressure acting beneath an elastic diaphragm through a metal spindle such as g closes the electric circuit by the use of a contact-breaker such as o, o, and clutches m, m, thereby forming an electrical connection with the solenoid v, and so controlling the steam-valve C, substantially as and for the purposes set forth and described, and illustrated by the drawing. (Specification, 3s. 6d.; drawing, 1s.)

No. 17656.—15th March, 1904.—FREDERICK WILLIAM SEARS, of Wellington, New Zealand, Survey Draughtsman. A process for imprinting matter upon photographic negatives.*

Claim.—A process for imprinting matter upon photographic negatives, the same consisting in first taking an impression of the desired matter from a litho. stone, plate, type, or other device with a suitable printing-ink upon the prepared surface of a transfer paper, laying such paper upon the negative so as to transfer the impression to it, and then strengthening such impression and fixing it upon the negative, substantially as specified. (Specification, 1s. 6d.)

No. 17661.—16th March, 1904.—UNITED SHOE MACHINERY COMPANY, of Paterson, State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, and having a place of business at 205, Lincoln Street, Boston, Massachusetts, United States of America (assignees of Frederick Jesse Nash, of Somerville, Middlesex, Massachusetts aforesaid, Manager). Improvements in or relating to machines for splitting leather or like material.*

Extract from Specification.—The machine of the present invention is provided with a splitting-knife and a pair of feed-rolls, one of which rolls is held in rigid relation to the knife at a distance from the plane of the knife equal to the desired thickness of sole, while the other feed-roll is yieldingly mounted to enable it to adapt its position to the thickness of stock being fed. The rolls force the stock against the knife, and the sole passes between the rigidly sustained roll and the knife, while the surplus material split off from the sole passes between the yieldingly mounted roll and the knife. The rigidly sustained feed-roll is adjustable to adapt the machine for evening different grades of soles, and means is provided, shown as a pointer movable over a graduated plate, for indicating to the operator the degree of adjustment of the roll for each grade of sole. It is desirable to mark the soles to indicate their grade, and the machine of the present invention is preferably provided with a stamping or other marking mechanism for this purpose. The stamping mechanism shown as embodying one form of this feature of the present invention comprises a recipro-
cating member and a normally stationary co-operating member. One of said members supports a plurality of dies, any one of which may be brought into position for stamping the desired mark to indicate the grade or thickness of soles being evened. As shown, the dies are carried by the normally stationary member, which, to this end, is made in the form of a rotatable block with dies secured in or upon its periphery. Preferably the die-carrying member or die-carrier, as it may be called, is arranged to be adjusted for putting the proper die into operative position by means which is operated simultaneously with the means for adjusting the rigidly sustained feed-roll. By this arrangement the stamping mechanism is always adjusted so that it will mark the sole in accordance with the grade for which the evening mechanism is adjusted. Preferably the die-carrier will be so constructed and arranged that when it is adjusted for marking thin stock its acting face will be brought closer to the reciprocating member than when it is adjusted for marking thick stock, in order that the stamping mechanism may act uniformly on stock of different thicknesses.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 12s.; drawings, 3s.)

No. 17664.—15th March, 1904.—GEORGE THOMAS BOOTH, Manufacturer, and WILLIAM BREW, Engineer, both of Christchurch, New Zealand. An improved front-wheel lift for ploughs.*

Claims.—(1.) In a front-wheel lift for ploughs, the general arrangement, construction, and combination of parts, substantially as specified. (2.) In a front-wheel lift for ploughs, a hanger-bar upon the front-wheel stalk, pivotally mounting a lever, the outer end of which bears upon the lower part of the front-wheel clutch to cause it to slide upon the front-wheel stalk when the lever is rocked by suitable means, as specified. (3.) In a front-wheel lift for ploughs, in combination with the front-wheel clutch upon the front-wheel stalk, a hanger-bar upon the stalk and a bent lever or levers pivotally hung upon the hanger so that its forward portion or portions will come below the said clutch, and a connecting-rod attached to the other end of the lever or levers for the purpose of rocking it or them from a lever accessible to the driver of the plough, as specified. (4.) In a front-wheel lift for ploughs, as specified and in combination, a boss upon the front-wheel stalk between the forks of the front-wheel clutch and a set screw in the boss, as described, and for the purpose explained. (Specification, 3s.; drawing, 1s.)

No. 17665.—15th March, 1904.—GEORGE THOMAS BOOTH, Manufacturer, and WILLIAM BREW, Engineer, both of Christchurch, New Zealand. Improvements in or relating to skeith-buckles.*

Claims.—(1.) A skeith-buckle for ploughs that shall be capable of acting either as a fixed or swivelling buckle upon the same mounting. (2.) In skeith-buckles, the general arrangement, construction, and combination of parts, substantially as set forth and for the purposes specified. (3.) In skeith-buckles, means for rendering the skeith operable either fixed or swivelled on the same mounting, comprising a collar on the skeith-stalk capable of being secured thereto, said collar being between bosses on a plate mounted on the plough-beam, through which bosses the stalk passes, and to which the same is secured when it is to be used fixed, but when it is to swivel, freed from the bosses and secured to the collar between the same, as specified. (4.) In a skeith-buckle, in which the skeith may be used fixed or to swivel as desired, lugs or abutments on a collar on the skeith stalk that limit the radial movement of the skeith when swivel mounted, as set forth. (Specification, 1s. 6d.; drawing, 1s.)

No. 17707.—28th March, 1904.—GEORGE THOMAS ADAM, of Prebbleton, New Zealand, Farmer. Improved means for securing breeching-straps to the shafts of vehicles.*

Claim.—Means for fastening the breeching of harness to vehicle-shafts, comprising, in combination with a breeching and a ring held therein, a hooklike device, that is secured upon the vehicle-shaft, in which the ring on the breeching engages, said hook being belted or sagged, and having a rigid prong or horn of a length sufficient to prevent the ring, when the horse is harnessed to the vehicle, from coming out of the device, substantially as described. (Specification, 2s. 3d.; drawing, 1s.)
