and boiling water poured upon it, the mouth of the coffee pot is fitted with a strainer, and the vessel reversed. The hot heater is then dropped into the tube, which causing the rapid generation of steam, forcibly expels through the strainer or filtering material, the clear decoction of coffee, which is received in a suitable vessel for serving.

The claim is to the mode of constructing apparatus to act as a filter, being inverted, and aided by the application of heat.

JOHN WHITE WELCH, OF AUSTINFRIARS, MERCHANT, for an improved reverberatory furnace to be used in the smelting of copper ore, or other ores which are or may be smelted in reverberatory furnaces. (A communication.) Rolls Chapel Office, January 21, 1842.

This furnace has two chimneys or flues, leading away in opposite directions from the circular basin or body of the furnace to two upright chimney-stacks, by means of which the requisite draft is obtained. A rapid current of flame, heated smoke, gas, and air, proceeds from the fire in a fire-place situated on one side of the furnace, over a low wall, called the fire-bridge, into the body of the furnace, at the upper part thereof, and, striking against the arched dome, is deflected or reverberated downwards upon the ores, or other matters lying on the floor of the furnace, and being divided into two currents, passes away to the chimneys. The heated gases, &c., are deflected down upon any ores, &c., which may be placed in the passages, which slope downwards towards the body of the furnace. The ores are fed into these passages from hoppers placed above, and as they become roasted or calcined, are pushed down into the main body of the furnace, by means of iron rabbles introduced through suitable openings made for that purpose.

Furnaces thus constructed are said to be applicable to the calcining or melting of copper or other ores, previously prepared and mixed in the usual manner.

The claim is to the improved reverberatory furnace before described; the novelty and the chief distinction between such improved furnace and those in common use being, that the current of flame, heated smoke, gas, and air, which proceeds, in the usual manner of ordinary reverberatory furnaces, from the fire-place, and over the fire-bridge into the body of the furnace, (instead of proceeding onward away from that body by one flue or passage to the chimney, as is the case in ordinary furnaces,) in the improved reverberatory furnace divided into two separate currents, which pass away laterally from the body of the furnace in opposite directions, in

93

order to go by two distinct flues or passages to the chimneys; in each of which flues or passages part of the ore, (regulus or imperfect metal,) which is to be operated upon may be placed, so as to receive a heating action from the divided currents of flame, heated smoke, air, and gas, passing through cach of the said passages respectively; so that two flues or passages, both having ore in them, are heated by the same fire, and with an economy of fuel. The improved reverberatory furnace may have two distinct vertical chimneys; or the said two vertical chimneys may be brought together into one vertical stack or chimney, by means of suitable flues or passages extending from the lowest part of the two vertical chimneys, to lead into the lower part of the said one stack or chimney, if that mode is preferred.

WILLIAM WARD ANDREWS, OF WOLVERHAMPTON, IRONMONGER, for an improved coffee-pot. Enrolment Office, January 21, 1842.

Within the body of the coffee-pot is placed a perforated box furnished with a movable top, which is held on by a clutch and ring; within this perforated box, and connected with it, is a perforated pyramid or cone, the base of which communicates with a waterpassage at the bottom of the coffee-pot; at the back of the coffee-pot, close to the handle, there is a forcing-pump fitted with a solid piston or plunger, and near the top of the pump-barrel there is a lip and cover, for pouring in boiling water. The piston being raised to the top of its working-barrel, boiling-hot water is poured into the lip, which flowing down the pump-barrel, passes along the water-passage, up through the perforated cone, into the perforated box in which the ground coffee had been previously deposited, and thence into the body of the coffee-pot. The piston is then forced down, which drives the small quantity of water contained in the pump-barrel through the coffee-box into the body of the pot, whence it can be drawn off by a spout of the usual construction.

The patentee claims "the improved coffeepot, as described, whereby I am enabled to force the boiling-hot water, of which the coffee is to be made, by means of a solid piston and force-pump, through the coffee, while the coffee is contained in a fixed closed and perforated box."

Neither the mode of using, nor the advantages supposed to be obtained by this improvement, (?) are by any means clearly set forth in the specification. Whether the pumping action is to be continued for any length of time, or whether the magic influence of one small quantity of water forced through the coffee by manual pressure, while

NOTES AND NOTICES.

Fire-proof Cement.-Mr. Martin, of Blackfriarsroad, has invented a fire-proof cement, which has been already used at the Earl of Sefton's residence, in Belgrave-square, at Stafford-house, &c., and which, we are informed, is intended to be used by Mr. Barry, the architect, at the new Houses of Parliament.-Court Journal.

Mr. Barry has done himself a great deal of credit by his decision on this subject, and we shall be glad to find his example followed by other surveyors of

public buildings. We would more particularly all lude at present to the British Museum and National Gallery, the literally invaluable contents of which are in hourly danger of destruction from the combustible nature of the floors and linings of the walls, and the tinder-ish state in which they are kept by the hot air and water flues running under or alongside of the wood-work. Since Mr. Martin's fireproof composition has been brought forward, there is no excuse whatever for exposing these, or any other of our public institutions, to the danger of con⚫ flagration. The composition alluded to is the same which Mr. Cubitt, the eminent builder, has employed at his extensive factory at Thames Bank, in place of wood, for almost every purpose to which the latter is applicable in buildings. It has been also used for floorings, to a considerable extent, in the new houses which Mr. Cubitt is engaged on in Belgrave-square and its neighbourhood. - ED. M. M.

Mostyn Foundry Marine Steam-engines.-On Thursday last a new steamer, called the Taliesin, was launched at the building-yard of Messrs. Eyton Brothers, at Mostyn, Flintshire. She is entirely owned by Messrs. Eyton; is intended to ply on the Liverpool and Mostyn station; and has been modelled so as to combine capability of stowage with speed. A pair of 45-horse steam-engines, for the Taliesin, are now in the course of erection at the Mostyn Foundry. These engines have been recently invented by Messrs. Eyton, being on an entirely new principle, combining extraordinary lightness with power and economy of space. The two engines weigh about 12 tons, have no beams, and only occupy about four feet, longitudinally, of the vessel's hold. They have another advantage in long connecting-rods, and the smallest, possible amount of friction. These engines are equally applicable to steamers of the lightest as of the heaviest class, from a river boat drawing one foot of water to the first-class war steamer.-Liverpool Albion.

[We presume that the weight here assigned to the engines is exclusive of the boilers; but even with that qualification, it is surprisingly-indeed, we may almost say incredibly-small. We shall be glad to receive some farther account of these engines.-ED. M. M.]

Electro-Magnetic Railway Controller.—A private exhibition of Messrs. Wright and Bain's Patent Elec tro-Magnetic Railway Train Controller took place on Thursday evening last, at the Royal Polytechnic Institution, Regent-street. The object of this invention is to prevent those dreadful accidents which 80 often occur under the present system of working railways. These improvements were illustrated by working models, which clearly showed that, in the event of any obstruction on the line, disarrangement of switches, or leaving open of cross-road gates, &c., timely warning would be given to the engineer; and, in the event of his not regarding it, a loud signal would then be given, and the train stopped without his aid, before it reached the point of danger.

Intending Patentees may be supplied gratis with Instructions, containing every particular necessary for their safe guidance, by application (post-paid) to Messrs. J. C. Robertson and Co., 166, Fleet-street, by whom is kept the only COMPLETE REGISTRY OF PATENTS EXTANT, (from 1617 to the present time). Patents, both British and Foreign, solicited. Specifications prepared or revised, and all other Patent business transacted.
