:ssage 22 therein, which communicates with
said passage 10. When the screw 21 is turned
in one direction, the outer end of this passage
becomes exposed, and air is then free to pass
s therethrough into or out of the passage 10.
After coffee and water' have been placed
within the urn, as ordinarily, the crank 16 is.
otated so as to impart rotary motion to the
.-stons12in the directions of the arrows shown.
IFig. 2. This will cause the liquid tobe drawn
npward through the gage 8 and around within
he circular chambers 11 and up hiou"h the
t.be 19 and pipe 20. This circulation of the
coffee will continue as long as the pistons are
15 rotated. After the operation has been com-
n.eted the thumb-screw 21 may be rotated so
_sto expose the outer end of passage 22 therein,
and air is thus parraitted to pass therethrough
into the passage 10, so as to return the liquid
20 within the gage to its natural level.
In will be seen that the pump herein de-
seribed may be readily attached. to an ordi-
nary urn, and by means thereof a circulation
of coffee may be quickly established..
25 Haring thus.described my invention, what
claim as new, and desire to secure by Ietters
Patent, is-
". In combination with an urn and its gage,a removabie pump attached to said gage where-
by a continuous circuit of liquid may be drawn
from and into the urn through said gage, and
an air-vent connected with the pump to be
opened when said pump is not in use to cause
the liquid to return to its level.
2. In combination with an urn and its gage,
a removable pump-casing at one end "Of the
gage. a channel between the casing and the urn
and a pump within the casing whereby a con-
tinuous flow of liquid is drawn from, the urn
and through the channel by way of said gage.
3. In combination with an urn and its gage,
a removable pump-casing at one end, of the
gage,a channel between the casing and the urn,
a pump within said casing whereby a contin-
uous circuit of liquid may be drawn from and
into the urn by way - of the channel through
the gage, and an air-vent connected to said
pump-casing to be opened when the pump is not
in use thereby causing the liquid to return to
its level.
In testimony whereof I affix my signaturein
presence of two witnesses.
