ABSTRACTS OF SPECIFICATIONS OF ENGLISH PATENTS RECENTLY

ENROLLED.

William Chesterman, of Burford, Oxford, Gentleman, for improvements 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 Alexander 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 inkholder, 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, the 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.
