No. 27499.—24th March, 1910.—ARTHUR RICHMOND CHRISTIAN, Pattern-maker, and ERNEST ALFRED REYNOLDS, Fibrous-plasterer, both of Christchurch, New Zealand. Improved means for causing trolley-poles to be lowered when such poles accidentally disengage the wire.*

Extract from Specification.—In trolley-poles of this description there is a serious danger of the trolley, should it accidentally disengage the wire, fouling some portion of the overhead gear of the permanent-way, as, owing to the absence of the downward pressure exerted upon the trolley by the wire, the spring carries the pole upwards, and maintains it in this condition until it is again replaced by hand. The object of the present invention is therefore to provide means whereby this momentary upward movement will cause the compression of the spring or springs to be sufficiently relaxed to allow the pole to fall back again by reason of its own weight to a point below the wire where it will be in no danger of coming in contact with any of the overhead gear, and means are also provided whereby the pole may be simply and expeditiously replaced with its trolley in contact with the wire.

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

(2.) The improved indiarubber and the like stamp, and the process for manufacturing same, substantially as described and set forth.

(Specification, 4s. 6d.)

No. 27832.—6th June, 1910.—WILLIAM WALTER WAKELY, of Featherston, New Zealand, Flaxmiller. Improvements in flax-stripping machines.*

Extract from Specification.—The invention consists in mounting the drum-spindle in bearings that are capable of sliding in the side frames of the machine. These bearings are then cushioned at their backs by means of long helical springs that project from holders formed in the frame, and thus serve to keep the drum pressed up to its proper position in relation to the beater-bar.
