NEW WIND PUMP.

A very ingenious wind pump may mow be inspected on the premises of Mr Williams, engineer and iron-founder, Christ church. The. pump is an American patent by A. P. Brown, and was shown at the Sydney Exhibition, where it was purchased for Mf J. E. Brown, who intends to erect it on his farm at Swannanoa, Eyreton. Hitherto the drawback to the employment of wind pumps has been their liability to damage by gales of wind, but this fault is entirely removed in the machine under notice, indeed it is the primary point for which the patent w*s granted. The machfne now in Mr Williams' yard is a sme 1 ! one, but the pniK^ple on which it is worked can of course be applied to any size. There are six sheet iron blades 18iri by J6in on iron arms which work in a socket in the centre of each plate. On each arm there is a ol&rong wire spring, and in each socket Ufere is a slit in which a small pin pro-

When, therefore, the wind blows above a certain strength, instead of the pump bein( operated upon so violently as to iri£Jr< the maohineiy, the blades revolve a kftU on the shaft according as the wind pressure affects the spring, and a diminishec face is at once offered for the wind to ac upon?; thfuay however violent a gale may be blowing,, the pump cannot be workec beyond a certain speed, inasmuch as the wind increases in strength so are thefacei •f the sails firmed more ifl an angle to iti deereaaiaftUw space subject to wind in« luence, This is an invention that has long been required, for it prevents, all anxiety 1 «U ibft* ptitrip in rough weath'6r, and it fiUtto doubt be extensively copiedi AttWmM tb me wind pump is a large perM^Qicular sheet of iron, affixed to the fhsrtjpuii' whivh the ■ sails * arß^ftcwdj and actinglik^theftaHof.avan^jo that the least alteration in the direction of the wind causes the sails to. answer to it instantaneously.

Another ad- . vantage, also, is that the smallness of $c ropes, as compared with timber frame- , Work,. prevents wind being diverted from
