whereby pulsations are given to the linings surrounding or adjoining the teat-chambers of teat-cups, or to tongues, bags, or similar devices placed within the teat-cups, by bringing them alternately under the influence of a vacuum and the atmosphere, the interiors of the teat-chambers being subjected to a continuous partial vacuum. (2.) In milking-machines, the use of a vacuum pulsator, secured to or supported by the usual claw, by means of which the spaces surrounding or adjoining the teat or milk chambers of one pair of teat-cups are brought under the influence of a vacuum, while the spaces surrounding or adjoining the teat or milk chambers of the other pair are brought under the influence of the atmosphere and continued alternately in each pair, substantially as described. (3.) In milking-machines, a pulsation cylinder having a compound piston therein, said cylinder being provided with ports and passages in communication with an identical valve cylinder having a similar piston, said cylinders being in communication with a vacuum-producer and the atmosphere, and the pulsation cylinder also communicating with the spaces surrounding or adjoining the linings or corresponding devices in the teat-cups, substantially as described with reference to Figs. 5 and 6 of the drawings. (4.) In milking-machines, a pulsator operated by a vacuum and consisting of the combination of the cylinders, pistons, ports, and passages substantially as described and explained, and as illustrated in the drawings.

No. 18337.—17th August, 1904.—ERNEST MOSS, of Christchurch, New Zealand, Mechanic. Coin-freed apparatus for stamping or franking letters, telegrams, and the like.*
[NOTE.—The title in this case has been altered. See list of Provisional Specifications, Gazette No. 74, of the 1st September, 1904.]

Brief Description. — When the machine is set to impress, say, a penny stamp, assuming a sovereign to have been placed in the machine, the pointer 8 is swung round the arc 10 until it rests in the notch 11 opposite the figure 1. The motion of the pointer also moves the casting 16 and cam 17, which will bring the mechanism bearing the penny stamp to a vertical position under the pressure hereafter to be described. At the same time the cam-race 17 will have thrust the bar 21 backwards, and a movement to correspond will be communicated to the block 24 through rod 23. This will set the machine to impress the penny stamp and to record such impression when the handle 2 is actuated by suitable mechanism for the purpose. Provision is also made for preventing more than one stamp or impression being obtained for one cycle or movement of the machine.
[NOTE.—The above brief description of working is inserted in place of the claims.]

No. 18353.—20th August, 1904.—WILLIAM FAIRWEATHER, SEN., JOHN FAIRWEATHER, and WILLIAM FAIRWEATHER, JUN., all of Walter Street, Blenheim, New Zealand, Engineers, &c. Improvements in or relating to flax-strippers.*

Claims.—(1.) The combination consisting of a grinding-wheel mounted on a spindle and having a rotary and longitudinal movement in bearings by means of a crank-handle or other device, the bearings to be part of the drum-cover or a separate equivalent frame, and having screws to adjust the wheel to its work—drum speed grinding speed. (2.) The correlation of feed-rollers and beating-bar whereby the flax is presented to the drum more radially, and the machine wants no ribber. (3.) Side plates on the ends of feed-roller, between the teeth of same and their bearings, preventing the flax getting between their ends and their bearings, and keeping the flax from getting over the side of drum. (4.) Flat spring to give the beating-bar resiliency.

No. 18377.—29th August, 1904.—JAMES CHARLES PARKE KIRKWOOD, of 14, Ebor Street, Wellington, New Zealand, Electrician. Improved regulating apparatus for electric arc lamps.*

Brief Description. — The improved regulating apparatus for electric arc lamps comprises a thermo-expansive wire or wires led over insulated pulleys suitably fixed to the frame of the lamp, one end being fixed electrically to an insulated terminal, and the other end to a lever, whereby the expansion due to heating by the passage of an electric current is “taken up” by a spring on the other end of the said lever, thereby raising a grip-lever, which engages and raises the top carbon from the lower carbon, and thus strikes the electric arc, combined with a device in the form of a thumb-screw for regulating the length of and the time of striking the arc; a small roller fixed to the frame and bear-

ing against the top carbon so as to keep it from being pushed to one side of a tube which contains the piston or plunger and the top carbon-holder, and by a device of one or two flexible wires or cords fastened at one end to the lower frame which carries the bottom carbon and the globe which encloses the arc, and the other end the grip-lever, preventing the pull of the spring on the main lever from drawing the grip-lever and the top carbon to one side, and the arrangement of the lower frame (which carries bottom carbon and globe) which keeps the globe pressed against a plate fitting its top opening, the said plate being held away from the main frame above by three legs, and is prevented from dropping when the globe is removed by two pins in the lower frame supporting it one on either side. Two springs, one on either side, are used to keep the globe through the lower frame pressed against the said plate, and by the use of a smoothly fitting piston or plunger in a tube fixed in the centre of the lamp and being part of the main frame, the said piston or plunger although being a close fit to the tube is free to move up or down (as the case may be) as the air leaks by it. A pin is fixed inside this piston or plunger, and carries, very loosely hung, the top carbon-holder, in which the top carbon is jammed or fixed. This said piston or plunger being fixed in the tube as described prevents the too rapid descent of the top carbon, but moves down slowly as the air leaks by it, substantially as described.
[NOTE.—The above brief description is inserted in place of the claims.]

No. 18380.—30th August, 1904.—WALTER WILLIAM PILKINGTON, of Victoria Street, Wellington, New Zealand, Accountant, and LUKE NELSON NATTRASS, of Lower Hutt, Wellington, New Zealand, Mechanic. An improved churn.*

Claims.—(1.) A churn comprising a vessel open at the top, trunnions upon the sides of the vessel, brackets upon which the trunnions rest, a plunger having perforations and fitting the vessel freely, a plunger-rod attached to the plunger, a cover fitting the top of the vessel and acting as a guide for the plunger-rod, a lever pivoted to the plunger-rod, and a standard to which the lever is fulcrumed, as set forth. (2.) A churn comprising a vessel open at the top, trunnions having heads and fixed to the sides of the vessel, brackets upon which the trunnions rest, keepers pivoted to the brackets and secured by thumb-screws, a plunger having perforations and fitting the vessel freely, a plunger-rod attached to the plunger, a cover fitting within the top of the vessel and having a flange fitting over the upper end of the vessel, a lever pivoted to the plunger-rod, a standard to which the lever is fulcrumed, and a draw-off plug fitted into the lower part of the vessel, as set forth.
