page_text: NOW KNOW YE, that in compliance with the sand proviso, 1, the San
William Paliner, do hereby declare that the nature of my said Invention,
and the manner in which tho same is to bo performed, aro fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention relates, first, to improvements in vessels for making infusions
or decoctions of coffee, or of other matters. Secondly, my Invention relates
to improvements in vessels for cooking. And thirdly, my Invention relates to
apparatus for measuring dry granulated matters, such as tea, coffee, &c.
And in order that my Invention may be most fully understood and readily
carried into effect. I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents the section of a vessel suitable for making infusions of
coffee or other matters; this vessel consists of two parts a and b, the part b
being to contain the infusions when obtained, and the part a is for placing in
the ingredients for infusion, and it is the mode of constructing the upper part a,
which constitutes the first improvement under the present Patent. c is a
partition which divides the upper and under parts of the vessel a, b; in this
partition is formed a small hole d (over which is placed a strainer d', as shown
in the Drawing), through which the infusions will flow, but owing to its being
very small, the liquor will flow through very slowly; and the apparatus shown
is such, that the upper vessel being filled with water it will take about five
minutes flowing through, but this time may be varied by having a slightly
larger or smaller holo d; and there may be several serows with holes d
applicable to the same vessel, by which the time of running off of the fluid
may be varied, depending on the time the particular matter under process.
should be submitted to be soaked in the water used for obtaining the infusions.
For it will be understood that this improvement consists in applying so small a
hole that the matter to be treated should be allowed to sonk only for a given
time, and that time to be determined by the size of the hole, and the con-
sequent time the liquor will occupy in passing through the hole. a, e, is a
cylinder, having a handle, which fits within the upper part of the vossal a, b,
and the cylinder a has a filtering fabric of cotton or other fibre stretched over
its lower end and fastened by sewing it to the cylinder, as is shewn, or by other
convenient means. This apparatus constitutes the filter, and is placed in the
vessel a, as is shown in Figure 1, and is kept from coming in contact with the
partition c, as is shown. The coffee or other matter to be treated is to bo

page_text: placed in the filter e, and boiling water poured into the vessel a so as to fill it;
the coffee or other matter will then remain soaking in the water, and the
infusions will flow through the filter only so fast as the hole d will carry it off,
thus will the soaking of the coffee or other matter be prevented soaking
longer than necessary, and no attention will be required to observe the time
required for the soaking.
Figure 2 shows the section of another vessel, similarly constructed to
that above described, excepting that the hole is so large that it would
carry off the liquor produced too fast to allow of the soaking of the coffee or
other matter being continued for any length of time, so far as the hole d
is concerned, but, by having the filtering material capable of being raised
and depressed, as is shewn in Figure 2, the extent of the filtering surface
would be contracted to the size of the opening d, and thus prevent any
material quantity of the liquor passing through the filter till the filter is
raised; thus, supposing coffee to be put into the filter when in the vessel a,
it will be ovident that if the filtering material touch the surface of the
partition call over, the only part where filtration will go on will be over
the orifice d, and this will be comparatively to a small extent compared with
the extent of the filter; it will therefore follow, on pouring water on to the
coffee or other matter in the filter, that the matter so treated will remain
soaking till the filter is raised up, and kept raised by the studs g, 9, of the
handle of the filter being caused to rest on the projections h, h, in the vessel a,
when the whole area of the filter will be brought into action; and it is this
mode of using a filter, combined with a hole, which constitutes another im-
provement. In making dedoctions the ingredient must be first boiled, and
then poured into the vessel a, when the clear liquor will run through into the
lower vessel, as before described.
Figure 3 shews a section of a similar vessel for cooking to that shewn at
Figure 1; there is a strainer used to guard the hole from filling up, but as
this vessel is intended to cook eggs, the strainer need not be so large as
when making infusions. This apparatus acts on a similar principle to that
of Figure 1, whereby the quantity of water used is only allowed to pass away
in a time which will be sufficient to cook the eggs placed in the upper part of
the vessel a, b; the eggs to be cooked are to be placed in the basket or reticu-
late cylinder e, e, and boiling water poured in to fill the vessel a; the cover is
then placed on, and by the time that the water has run from the upper part a
to the under part 6 of the vessel a, b, which will be in about five minutes, the
eggs will be cooked.
I will now describe the third part of my Invention, which relates to an

page_text: apparatus for nieasuring granulated or other matters. such as ten, coffee. &c
Figure represents two external views of a vessel, having the apparatus applied
thereto; Figure 5 shows two sections of the vessel, and mensuring apparatus;
and Figure 6 shews three views of the measuring apparatus, separately. The
vessel may be of any desired size and shape, and may have a measuring
apparatus applied thereto of such capacity as will draw off the quantity wished.
The measuring apparatus consists of two cylinders y and a, the cylinder y
being affixed to the vessel, and the cylinder is placed within the cylinder y,
so that it may revolve therein, as is clearly shown in the Drawing. In the
cylinder y there are two openings, one into the vessel, and the other at the
opposite side; and in the cylinder there is one opening, by which arrange-
ment, when the opening of the cylinder a is opposite the opening in the
cylinder y,
which opens
into the vessel, then the granular matter contained
therein may be shaken or allowed to run into the cylinder 2, and when the
cylinder a is turned round so that the opening therein comes opposite the other
oponing of the cylinder y, the granular matter will run therefrom. And it
should be remarked that it is important to call attention to the circumstance
that the outer and inner cylinders y, a, are so far apart that any grain cou-
tained in the vessel would be allowed to go between the two cylinders, and
yet permit the inner cylinder to move round freely; w is a cover to the outer
opening of the cylinder y.
Having thus described the nature of my Invention, and the manner in which
the same is to bo performed, I would have it understood that I do not con-
fine myself to the precise details shown and described, provided the peculiar
character of either of my improvements be retained; but what I claim is,-
First, the mode of constructing vessels for obtaining infusions and decoctions,
as described in respect to Figure 1, where the time of allowing the material to
be soaked is regulated by a small hole; and I also claim the mode of regu-
lating the speed of filtration when making infusions, by combining a filtering
surface which can be raised with a small hole, as described in respect to
Figure 2.
Socondly, I claim the mode of constructing apparatus for cooking, by
regulating the timo of the operation by a small hole, as above described.
And thirdly, I claim the mode of combining two cylinders y and a, with a
space between them, for measuring granulated matters, as above described.
In witness whereof, J, the said William Palmer, have hereunto set my
hand and seal, the Second day of September, in the year of our Lord
One thousand eight hundred and forty-two.
