The Schedule referred to in these Letters Patent aud making part of the same. 1
To all whom it ma/ afconce/m:
Be it known that I, W. C. G. Ensnmn, of Nether Kinnedder, Dunfermline, Fifeshire, in Scotland, have invented a new and useful Improvement in. Coffee-- Pots; and I do hereby declare .that the following is 'a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the' same, reference being had tothe accompanying drawings, forming part of this specification. i
This invention relates to improvements in coffee pots, designed to provide a better arrangement forextracting the essence of the jcoffee, and separating it from the grain, than any now in use; and
It consists in the peculiar' construction of the strainer, whereby two increased straining-surfaces are produced, of unequal fineness, as will be hereinafter more fully described. f
Figure l represents a sectional elevation of my improvernent, applied to a coi'eepot; and
Figure 2'represents a section ofthe same', taken on the linex :t of iig. 1. r'
Similar` letters of reference indicate corresponding parts.
. AI represents .a sheet-metal vessel, preferably of round forni, and having a conical bottom, adapted. to titiuto the opening through the top of an ordinary tea or ooi'ee-pot.
v Withiuthe vessel A, I provide a perforated cone,
` B, having an opening in the top.
Within this cone, and extending through a hole in the bottom of the vessehA, I provide a perforated tube,'C,the said perforations being smaller than those Yinthe cone B.
The said tube is stopped at the top, and opened at the bottom; l p' A key, E, may be passed through the lower end of the latter, below the bottom of the vessel A, to hold the cone B down to the said bottom, but so arranged Vthat it may be readily detached, from time to time,
for removing any of the finer grains that may pass through the perforations of the cone. u
The ground coiiee is placed in the vessel A, above the cone B, and the hot water-poured thereon,'in any required quantity, and allowed tov stand a Vshort time, for the water to filter through the coffee and the perforated cone' and tube, which it readily does', and passes into the pot below,.taking up, at the same time, the strength of the coi'ee, but leaving'the solidmatter.
yHaving thus described my invention,
I claim as new, and desireto securel by Letters Patent- Y The strainer, constructed as described, of the cone B, provided with coarse perforation's, and the finelypertbrated tube C, extending vertically through said cone, both arranged as described, and adapted for at'- tachment to the interior of the case A, iu the manner set forth, for the purpose specified.
The above specification of my invention signed by me, this 29th day of January, 1869.
