No. 25083.—15th October, 1908.—JOHN ALFRED POWRIE, of Lower Hutt, Wellington, New Zealand, Builder. Improvements in water-strainers.

Extract from Specification.—A galvanised-iron tank I into which the water flows at A, passing through strainers B, C, and into the main tanks at outlet D. When the main tank is full the water rises in tank I and flows through outlet E into movable bucket F, which when full pulls lever G, lifts weight H, thus allowing water to flow through the bottom of tank I at L, thus flushing the strainers at C, B, as well as the tank I, and passes out at waste-pipe at bottom. Water runs slowly out of bucket F at J into waste-pipe K, allowing weight H to pull bucket F into its normal position after a certain space of time, at which time the weight will again close the waste-pipe at L. Straps M suitably fastened and fitting loosely may be used to steady the apparatus.

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

(Specification, 1s. 6d.; drawing, 1s.)

No. 25295.—30th November, 1908.—FRANCIS ERNEST ROSS, of Cambridge, Auckland, New Zealand, Farmer. Sanitary apparatus for use in milking-sheds.*

Extract from Specification.—The invention consists in providing a shute or shutes, which are connected by bars to a drain in such a way that the shute will, when in operation, be fitted to the back part of the cow or cows, so that while the milking is taking place the droppings of the cow will be caught by the shute, and thereby no part of the droppings of the cow will reach or fall into the receptacle holding the drawn milk; and in providing a means of removing the droppings from the drain in the manner detailed.

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

In the arrangement of cylinder No. 2 inside cylinder No. 1, together with its attachments, the lead weight and the metal rod C, for the purposes aforementioned, and as illustrated and described. (2.) In the arrangement of the gas-tap with its attachment, the bent metal strip being so placed that it is actuated by the rod C when said rod C travels down to it, all as described and illustrated. (3.) In the arrangement of the two flat metal springs 1 and 2 being so placed in electrical circuit with an electric bell, an electric battery, and an electric switch, that an alarm is given when the bent strip on gas-tap makes metallic connection with them. (4.) In the arrangement of the hinge and flat metal spring on rod C for the purposes as aforementioned, and as described and illustrated. (5.) In the arrangement of the metal tubing with its attachments, all as aforementioned, and as illustrated and described. (6.)
