No. 28046.—8th July, 1910.—FRANK PARRY, of Brightwater, British Columbia, Canada, Gentleman. Hat-pin guards.

Claims.—(1.) In a guard for the purpose intended, a body provided with a compartment, and a spring arm overlying the compartment, and a sliding member upon the guard adapted to swing and retain the arm within the compartment. (2.) In a guard for the purpose set forth, a body member comprising a compartment, and a spring arm overlying the compartment, both the body and the spring arm being provided with stops, a disc upon the rear end of the body, and a member slidable between said disc adapted when slid in one direction to force the arm within the compartment, and when slid in the opposite direction to allow the arm to swing from the compartment. (3.) In a device for the purpose set forth, a guard comprising a body, said body having a longitudinally extending compartment having its lower wall curved, the body being further provided with an integrally formed spring arm overlying the compartment, the under-face of the spring arm being curved, a pin-protector member provided with a V-shaped opening within the compartment, and a slidable member upon the guard for compressing the arm to swing one of its ends within the compartment.

(Specification, 3s. 9d.)

No. 28047.—8th July, 1910.—BENJAMIN FRANKLIN CRANWELL, of Henderson, Auckland, New Zealand, Agricultural Engineer. Improvements in and relating to apparatus for spraying fruit-trees and the like.

Claims.—(1.) Apparatus for the purpose indicated, consisting of the parts constructed, arranged, combined, and operating substantially as specified, and illustrated in the drawings. (2.) Apparatus for the purpose indicated, comprising in combination a revolving barrel to contain the spray-fluid, a pump, a motor for driving the pump, the suction-pipe of said pump passing through one trunnion-bearing and the delivery-pipe through the other trunnion-bearing of said barrel, substantially as specified and illustrated. (3.) In apparatus for the purpose indicated, the employment of means for heating the spraying-fluid, substantially as specified.

[NOTE.—Here follow three other claims.]

(Specification, 3s. 6d.)

No. 28053.—9th July, 1910.—THOMAS MILLER, of Ponsonby, Auckland, New Zealand, Engineer (nominee of Francois J. F. Benz, of Weltevreden, Batavia, Engineer). An improved steam-engine having an automatic valve-motion and an automatic changeable expansion.

Claims.—(1.) The improved steam-engine specified, consisting of the cylinder internally fitted with piston, springs of said piston carrying touchers set to engage and lift ball seated within ball-chest, whereby the inlet-valve is lifted automatically, handles and levers provided to lift by hand said inlet-valve, valve-spring set to control inlet-valve, flange for admitting boiler-steam, steam-space above cylinder and surrounding said inlet-valves, steam-hole, horizontal steam-hole, condenser-spaces, three-way cocks, exhaust-steam port, inlet-valve chest, horizontal steam-face, spindle provided to adjust opening of said inlet-valve and to be worked alternatively, short cylinders cut with square screw-thread, steam-holes in cylinder-wall, gear-wheel working on governor and working with either alternative discharge-valves connected by lever working on fulcrum, exhaust-lap, cylinder-cover, and clearance, constructed in the manner and for the purpose set forth, as described and illustrated.

[NOTE.—Here follow five other claims.]

(Specification, 5s. 6d.)

No. 28059.—12th July, 1910.—THE PITTLER UNIVERSAL ROTARY MACHINE SYNDICATE, LIMITED, of Norwich House, Southampton Street, High Holborn, London, England, Manufacturers (assignee of Wilhelm von Pittler, of Norwich House, Southampton Street, High Holborn, London, Mechanical Engineer). Improvements in rotary fluid-pressure machines.

Extract from Specification.—According to this invention, one or more concentric grooves or channels are provided in a stationary part of the machine in order to serve as working chambers. These channels are traversed by an abutment-slide, which is provided with slots and are normally shut off by the full portions of the slide. Upon the approach of the pistons which are working in the grooves, the abutment-slide, however, is adjusted in such a manner that its openings or recesses coincide with the grooves or channels, and allow the pistons to pass. The control of the abutment-slide is effected by a revolving cam in conjunction with the action of a pressure-fluid, in such a way that the latter balances the cam mechanism while the other eliminates the unreliability of the fluid-pressure-controlling device, and that at the same time the waste spaces are reduced in consequence of the accelerated controlling-action rendered possible by this combination.

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

(Specification, 5s. 6d.)

No. 28063.—12th July, 1910.—CHARLES CRAIG, of Kaiapoi, Canterbury, New Zealand, Inventor. Improved safe.

Claims.—(1.) A safe for comestibles, consisting of the parts constructed, arranged, and operating substantially as set forth and illustrated. (2.) A safe for comestibles, having sides and ends provided with reticular panels, and a hood having inwardly inclined walls and sides inclining therefrom, substantially as specified and illustrated. (3.) A safe for comestibles, having a hood provided with a hinged side, which may be used as a shelf, and having inwardly inclined walls upon each side, substantially as specified and illustrated.

(Specification, 2s.)

No. 28075.—13th July, 1910.—HENRY BERRY, of Croydon, Hunslet, Hydraulic Engineer, and GEORGE HUTCHINSON MANN, of 58 Sholebroke Avenue, Chapeltown Road, Mechanical Engineer, both of Leeds, in the County of York, England. Improvements in valves and valve-gear for internal-combustion engines.

Claims.—(1.) In internal-combustion engines of the four-stroke cycle type, a valve operated directly by an eccentric mounted on the half-speed shaft, the movements of the eccentric-strap being alternately increased and diminished by consecutive movements obtained from the main shaft or equivalent part having a one-speed movement. (2.) In internal-combustion engines of the four-stroke cycle type, in which the inlet and exhaust openings are fitted with a single piston or slide-valve, reciprocating the said valve by connecting it directly to a rocking-lever having a combined movement imparted thereto from an eccentric situated on the half-speed shaft, and an eccentric situated on the engine-shaft or other one-speed shaft, said actuating mechanism being so arranged that during certain periods in the cycle the combined movement obtained gives the valve a rapid opening-and-closing movement, and at another period has the effect of holding the valve stationary or almost stationary.

[NOTE.—Here follow two other claims.]
