We have the pleaſure to conform to the wiſhes of our Lea dents) by pre- ſenting them with a Plate and Deſcription of 2 Family Mi/l, which tully merits the reward beſtowed on it by the Society of Arts and Commerce” Indeed this Society ſeems likely to become the uſual medium by which the moſt valuable inventions are preſented to’ the public.

TEE PARTIE OR FAMIEN‘MIEL,

Invented by Mr.T. RusTALL, Wheelwright, of Bur brook- Heath, near Partſmauth, for which he ob:ained the Premium of Forty Guineas from the SOCLE LN OF ARTS AND COMMERCE.

HIS MYI promiſes to be of great public utility, as it can

be confſtruéted at a moderate expence, and ſtands 0a 2 fmall ſpace of ground. It may be worked within a room in a. farm houſe, or even.in a public kitchen, without occafioning‘much incumbrance,

Its peculiar excellence conſiſts in this circuniſtance;; thats from tlie vertical poſition of the ſtones, a(ion may be given to it without the intervention of.cogs or wheels: it may be uſed to grind malt, to bruiſe oats for FEE or to make flour, or‘for âll theſe Moles:; and it can eaſily be altered to grind fine or coarſe, as occaſion may reguire.

It may be worked by one man: but if two perſons‘are em- ploved, it will furniſh, in two hours, a ſufficient quantity of flour to ſerve a family of E or. eight perſons for a week. The far- mer, by a llotting half an hour's time in the evening for its ufe, may make comparative.experiments of the quality Sf his grain, and, at a trifling expence, provide himſelf with flour. from his own wheat, without fear of ſophiſtication, or. being liable to- the. caprice or defrauds.of a miller.

Repeated ſatisfa@tory expériments have been made with thig Mill before Members of the Society; and the original Mill is now in their repoſitory forthe infpedtion óôf the public.

Referenge to thè Plat& of(Fig. 19);

A, the handle of the Mill. B, oute of the mill„.ſtones, about 30 E diameter, Andfive inches thick, moving with its axis C.

D, the other mill-ftone, which is. ſtationary when uſed, but maybe placed nearer to, or further from, the moveable ſtone B, by means of three ſcrews paffing through the wood-block E, which ſupparts one end ofthe axis C, after it has paſſed through 2 perforation in thè centre of is bed-ſtone. Through this hole alſo the grain paſſes from the hopper Finto the Mill.

F, the hopper, to which an agitation 1s given by two iron pins‘fixed on the axis C, which alternately raiſe this hopper cón- taining the grain lat to be ground: the hopper ſinks again by its own weight; the corn is delivered“ by this motion through 2 ſpout, Aae from the ſaid hopper into the centre of the Mill behind, and through the.bed-ſtone, D.

G, a paddle ELEA regulates the quantity of corn to, be deli-- veréd into the Mill; a Dreatet or léſs quantity of which may- be furniſhed, by railing or lowering the paddle,
