ABSTRACTS OF SPECIFICATIONS OF ENGLISH PATENTS RECENTLY
William Chester man, of Burford, Oxford, Gentleman, for improve
ments in filtering different liquids. Enrolment Office, December 21, 1841.
Under this deceptive title we are presented with another new coffee-pot.
This coffee-pot is made of tin plate, with a wooden handle attached horizontally to one side of it; a hole is made in the bottom of the vessel, to admit a heater to enter a tube which passes up the centre of the pot. The ground coffee being placed in the vessel, 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. Joseph Gaucy, of North-crescent, Bedford-square, Artist, and Alex
ander Bain, of Wigmore-street, Cavendish-square, Mechanist, for improvements in inkholders. Enrolement Office, December 21, 1841.
The first of these improvements consists in placing a small forcepump at the bottom of the interior of the inkstand, the piston of which is raised or depressed by means of a screw, or other suitable contrivance ; when the piston is at the top of the working barrel, the ink flows into it through small openings made in its side for that purpose, .which ink, on the descent of the piston, is forced up a tube into the ink holder, or dipping-place. In a second modification, the piston-rod works through a stuffing-box in the closed top of the pump-barrel, and raises the ink in its upward movement. In a third modification, the pipe leading perpendicularly from the inkholder forms the piston-rod, the piston being affixed to its lower end, and working in a well at the bottom of the inkstand.
A second improvement consists in forming the inkstand of a horizontal cylinder, with a projecting spout or dipping-place on one side. When in a position for use, the ink flows into the dippingplace ; but when done with, thé inkstand can be turned on its axis; the whole of the ink flows back into the interior, and the spout rises up against an ornamental stop, which closes the orifice, preventing evaporation of the ink, or collecting of dust. In another
arrangement of this inkstand, the front is a circular glass plate, with a dipping-place, which turns in a fluid-tight joint, and allows the dipping-place to be raised up against the stop, as before, while the main body of the inkstand and its contents remain stationary,
The claim is, 1. To a mode of constructing inkstands by apply. ing a force-pump below the surface of the ink, in the vessel containing the ink; 2. To a mode of constructing inkstands by causing the ink vessel, (or part thereof,) containing ink, to move partly round, and, by the gravitating property of the ink , to supply ink to an inkholder for use. Moses Poole, of Lincoln's Inn, Gentleman, for improvements in steam
baths and other baths. Enrolment Office, January 13th, 1842.
A room is constructed in a steam-tight manner by being lined with sheets of lead or zinc; on one side, near the floor, there is an opening, furnished with shutters, by which the admission of atmospheric air can be regulated at pleasure, while on the opposite side of the room, near the top, another opening, similarly fitted, is placed for the escape of the impure heated air and steam. Light is admitted at the top by a double sky-light. A boiler (of copper is preferred) is furnished with a safety-valve, and also an apparatus for supplying it with filtered soft water. Steam is generated in this boiler under a pressure of from 10 to 20 lbs. upon the inch, for the purpose of supplying steam to the bath, and also for heating a quantity of water contained in an elevated cistern. Another elevated cistern contains a supply of cold water. Within the room or bath there are three rose heads, one above the other, connected with the hot and cold water cisterns in such a manner, that by regulating the cocks, a shower of hot or cold water, or of any intermediate temperature, may be obtained from either of these rose heads; so that a person may apply a shower of cold water to the head, warm to the stomach, and hot to the feet. The mode of using this improved bath is as follows:-The bather, on entering the bath, prepares himself by first subjecting his body to the shower from one or more of the rose heads, gradually increasing the temperature; steam is then gradually admitted, until the bath attains a temperalure of 80° or 100°. The floor is of wood, perforated with a number of holes for the escape of the water from the rose heads, and provision is made for the bather to sit or lie down; flexible tubes are also attached to the steam pipes, by means of which jets of steam may be directed to any part of the body. The steam bath having been continued long enough, the hot shower bath is again resorted to, gradually decreasing the temperature till it approximates to that of ihe external atmosphere. • The claiın is, 1. To the mode of producing a steam bath by the application of steam (generated under considerable pressure) within a room so arranged as to allow of a sufficient circulation of fresh atmospheric air, as above explained ; 2. To the mode of combining the use of a high-pressure steam bath in a ventilared room, with a rain douche, or water bath, whereby the skin is prepared before and after a steam bath, as above explained ; 3. The mode of regulating the temperature of douche baths, « whether rain or voluminous. a William Ilale, Engineer, and Edward Dell, Merchant, both of Wool
wich, for improvements in cases and magazines for gunpowder. Enrolment Office, February. 12, 1842.
These improvements consist in the construction of covered cases and magazines for gunpowder of cast or wrought tin, whereby cases containing gunpowder will not be chemically or injuriously acted on by the powder.
These cases are made six-sided, so as to possess considerable strength, and at the same time, to allow of a number of them being packed closely together. On the top there is a cylindrical neck, on which a male screw is cut or formed, blanks or spaces being cut' in three equidistant parts, to admit corresponding projections on the inside female screw of the cower to enter. The cover is held to the case by a quadrant-shaped bolt or pin, which prevents, its being detached when the case is opened.' Ou the inside of the cover is placed a leather or other washer, so that on placing the cover in its place, and turning it partly round, a close joint is made. These cases may be cast in moulds of either sand or metal, or they may be made of wrought tin soldered up. By this means, say the patentees, a covered case or magazine of any required size may be made, which, from the peculiar character of the metal, will retain gunpowder with great safety, and without the metal of which it is composed being prejudicially acted upon by the chemical properties of the gunpowder.
The patentees state that they do not confine themselves to the exclusive use of tin. But they consider tin, in an unalloyed state, to be best adapted for this purpose.

CHAPTER THE TWENTY-THIRD.
The secretary put his hand before his eyes to shade them from the glare of the lamp, and for some moments looked at Hugh with a frowning brow, as if he remembered to have seen him lately, but could not call to mind where, or on what occasion. His uncertainty was very brief, for before Hugh had spoken a word, he said, as his countenance cleared up :
« Ay, ay, I recollect. It's quite right, John, you needn't wait. Don't go, Dennis.»
Your servant, master," said Hugh, as Grueby disappeared.
« Yours friend, · returned the secretary in his smoothest manner. • What brings you here? We left nothing behind us, I hope ? »
Hugh gave a short laugh, and thrusting his hand into his breast, produced one of the handbills, soiled and dirty from lying out of doors all night, which he laid upon the secretary's desk after flattening it upon his knee, and smoothing out the wrinkles with his heavy, palm.
