PROVISIONAL SPECIFICATION.
Improvements in Tea or Coffee Urns.
1, EBENEZER BOYES, of Albert Road, Peckham, in the County of Surrey,
Wholesale Coffee Dealer, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to provide an urn for tea or coffee which
can be
swung into any convenient position for pouring and retained in such position
so as to avoid disturbance of the grounds or leaves, which can be readily removed
from the carrier, which will keep the contents hot for some considerable time, and
which will prevent the grounds or leaves from passing away with the liquor
through the spout.
I make use preferably of an earthenware jar fitted into a metallic case, and I
fill such space with charcoal or other non-conducting material, so as to avoid any
material loss of heat of the liquor in the jar. If desired the lid may also be
provided with an outer case and a space between them, which is filled as above
described.
The upper part of the outer case extends above the upper edge or flange of the
jar, and it is there provided on the outside with a straining chamber communicating
with the interior and with the pouring spout; the jar may also at such part be
formed with a pouring lip or flange to direct the liquor into the straining chamber.
I also provide the interior of the jar with a retaining ledge or flange just below the
upper edge or pouring lip, so that when the urn is greatly tilted, such interior ledge
or flange shall prevent the grounds or leaves from passing, to any great extent,
away with the liquor to the straining chamber.
I also provide the urn with trunnions, which are mounted in a frame or stand, and
according to my invention I provide means for retaining the urn in any position to
which it may have been tilted, so as to avoid the disturbance of the grounds or
leaves, which would be caused by allowing the urn to resume its originally vertical
position after each tilting thereof for pouring.
In order to make the urn readily removeable from its support, I make the
trunnions separate from the urn and I provide means for readily connecting and
disconnecting the urn and trunnions, the trunnions in such case.always remaining in
their bearings in the frame or stand.

COMPLETE SPECIFICATION.
Improvements in Tea or Coffee Urns.
I, EBENEZER BOYES, of Albert Road, Peckham, in the County of Surrey,
Wholesale Coffee Dealer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters marked thereon :-
The object of the present invention is to provide an urn for tea or coffee which
can be swung into any convenient position for pouring and automatically retained
in such position, so as to avoid disturbance of the grounds or leaves, which can be
readily removed from the carrier, which will keep the contents hot for some

page_text: with the liquor through the spout. -
In the accompanying drawings
Figure 1 is a vertical section,
Figure 2 is a front view and Figure 3 is a plan, of a tea or coffee urn showing
one method of carrying my invention into effect.
Figure 4 is a sectional view showing one of the trunnions and the coacting piece
at one side of the urn.
Figure 5 is an edge view of the coacting piece separately, and
Figures 6 and 7 are sectional views through the trunnion end and the coacting
piece showing the extreme positions the latter can take.
and
Figure 8 is a sectional view of a trunnion and its support showing a modification,
Figure 9 is an end view of Figure 8.
I will first describe the arrangement shown at Figures 1 to 7.
I make use preferably of an earthenware jar a fitted into a metallic case b, and I
fill the space between the case and jar with charcoal or other non-conducting
material so as to avoid any material loss of heat of the liquor in the jar. If desired the
lid may also be provided, as shown, with an outer case c¹ and a space between them,
which is filled with non-conducting material. The upper part of the outer case /
extends above the upper edge or flange of the jar a, and it is there provided on the
outside with a straining chamber communicating with the interior of the urn and
with the pouring spont 2, a strainer being fixed within the chamber '; the jar a
may also at such part be formed with a pouring lip or flange a to direct the liquor
into the straining chamber bl. I also provide the interior of the jar with a retaining
ledge or flange a just below the upper edge or pouring lip a', so that when the urn
is greatly tilted, such interior ledge or flange a² shall prevent the grounds or
leaves from passing to any great extent away with the liquor to the straining
chamber.
I also provide the urn with trunnions d which are mounted in a frame or
standards and, according to my invention, I provide means for automatically
retaining the urn in any position to which may have been tilted, so as to avoid
the disturbance of the grounds or leaves which would be caused by allowing the
urn to resume its originally vertical position after each tilting thereof for pouring.
For this purpose I make the trunnions d and the holes in the standards e in which
they are mounted, slightly conical and I form a square d' near the smaller end of
the trunnion to receive a square holed washer d², and beyond said square dis
formed a screw ³ to receive a nut d and lock-nut d; thus, by screwing up the
nuts d' d³, any required amount of friction can be put on the trunnions d. also
fix in the larger end of each trunnion a stop pin do to act against stops e' on the
standards e to limit the motion of the trunnions, and consequently of the urn, in
either direction.
.In order to make the urn readily removable from its support, I, according to the
arrangement represented at Figures 1 to 7, make the trunnions separate from the
urn, and I provide means for readily connecting and disconnecting the urn and
trunnions, the trunnions in such case always remaining in their bearings in the
frame or standards e. For this purpose the inner ends of the trunnions are cach
formed with a tapered socket d and the urn casing has fixed thereto projections b
which are tapered to fit the sockets d' and have the smaller ends of such tapered
parts cut off at an angle to enable them to readily enter the said sockets. By the
peculiar form of the projections and sockets and the combination therewith of
the stop pins and stops e¹, the urn, can be turned within the limits of the stops
without danger of becoming accidently disconnected from its trunnions.
According to the modification represented at Figures 8 and 9, the trunnions are
carried by the urn but are readily removable from the standards e. In this
modification a hole is formed in each side of the casing b; a centrally perforated
disc fis fixed in such hole, partly by rivets passing through lugs
and through

page_text: the casing b, and partly by solder around the edge of said disc; a trunnion g
passed through the perforated disc, and its head g fits against the interior face of
the disc; the cylindrical part of the trunnion fits the hole in the disc, and on the
outer face of such cylindrical part is formed a square y² to receive a square holed
washer g³, and beyond such square is formed a screw 'to, receive a nut go, by
means of which any desired amount of friction can be applied to the disc between
the trunnion head and the washer 3. The outer ends 9° of the trunnions are
flattened to fit corresponding open slots in the standards e by these means the urn
with its trunnions can be readily removed from and replaced in its supports.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In a tea or coffee urn, the peculiar combination and arrangement of parts
substantially as herein shown and described and for the purpose stated.
2. A tea or coffee urn provided with trunnions mounted in a frame or standards
and arranged in such manner as to automatically remain in whatever tilted position
may be given to it and so that it can readily be removed from the frame or
standards, substantially as herein shown and described.
3. In tea or coffee urns, the combination therewith of a pouring spout, a straining
chamber communicating with said spout, a strainer within such chamber, and a
ledge or flange within the body of the urn and adjacent to the straining chamber,
substantially as herein shown and described and for the purpose stated.
