Henry Mackenzie at the Office of the Commissioners of Patents, with
their Petition, on the 14th May 1867.
We, BENJAMIN BARRETT, of Birmingham, in the County of Warwick, Silver
and Electro-plate Manufacturer, and HENRY MACKENZIE, of Birmingham,
aforesaid, Silver and Electro-plate Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN OR ADDITIONS TO EGG
BOILERS FOR THE TABLE," to be as follows:-
Egg boilers for the table as ordinarily constructed consist of a small boiler or
vessel provided with a lid or cover, in which vessel the eggs are boiled; the
said boiler or vessel is supported on legs, and is heated by a lamp placed on a
stand underneath the said boiler, the lamp stand being carried by the legs of
the boiler.
Our Invention consists of the improvements in or additions to the said
egg boilers herein-after described. We provide the edge of the lamp stand
with two, four, or other required number of small radial platforms or supports
to carry the egg cups; these supports may be made in one piece with the
lanıp stand or soldered thereto. Each of the said supports has a small peg
and conical seat at its upper side, upon which the hollow foot of the egg cup

to the side or other convenient part of the egg boiler, the said frame being
capable of rotating upon the said screw pin as a centre. The metal frame of
the minute or sand glass is provided with a handle by which it may be turned;
by giving a semi-rotation to the frame the minute glass is inverted, and the
sand from the upper bulb passes to the lower bulb in the usual way, and thus
indicates the time necessary for boiling the eggs. We connect the minute or
sand glass to the frame by means of concave bearing plates at top and bottom
which fit upon the convex ends of the said glass. One of these bearing plates |
is fixed and the other is moveable. The said moveable bearing plate has a
screwed stem which passes through the end of the frame, and is fixed by a
screw nut; by means of this moveable bearing plate a fresh minute or
sand glass can readily be fixed in the frame should the minute or sand glass

Patent.
NOW KNOW YE, that we, the said Benjamin Barrett and Henry Mackenzie,
do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
Egg boilers for the table as ordinarily constructed consist of a small boiler
5 or vessel provided with a lid or cover, in which vessel the eggs are boiled.
The said boiler or vessel is supported on legs, and is heated by a lamp placed
on a stand underneath the said boiler, the lamp stand being carried by the
legs of the boiler.
Our Invention consists of the improvements in or additions to the said egg
boilers herein-after described. We provide the edge of the lamp stand with.
two, four, or other required number of small radial platforms or supports to
carry the egg cups; these supports may be made in one piece with the lamp
stand or soldered thereto. Each of the said supports has a small peg fixed to
a conical seat at its upper side, upon which the hollow foot of the egg cup
fits. The egg cups are thereby prevented from falling from the platforms or
supports at the base of the egg boiler.
We also provide the egg boiler with a minute or sand glass for indicating
the time for boiling the eggs. The said minute or sand glass is carried in a
metal frame, which frame is connected by a screw pin and nut, or otherwise
to the side or other convenient part of the egg boiler, the said frame being

the minute or sand glass is provided with a handle by which it may be turned.
By giving a semi-rotation to the frame the minute glass is inverted, and the
sand from the upper bulb passes to the lower bulb in the usual way, and thu
5 indicates the time necessary for boiling the eggs. We connect the minute o
sand glass to the frame by means of concave bearing plates at top an
bottom, which fit upon the convex ends of the said glass. One of thes
bearing plates is fixed and the other is moveable; the said moveable bearin
plate has a screwed stem which passes through the end of the frame, and ma

Figure 1 represents in perspective an egg boiler for the table containing o
improvements; Figure 2 represents a portion of the egg boiler in vertical
section, and exhibits the construction of the minute or sand glass; and
Figure 3 represents, partly in vertical section and partly in elevation, the base 10
of the egg boiler, and exhibits the construction of the platforms or supports
and the feet of the egg cups. The same letters of reference indicate the
same parts in each Figure of the Drawing.

egg
The top of the egg boiler is closed by a cover e.
The legs b are provided with clips f for supporting the egg spoons 9, 9. At
the edge or periphery of the lamp stand c are two radial platforms or sup
ports h, h, for supporting the egg cups i, i; these supports are made in one
piece with the lamp c, or are soldered or otherwise fixed thereto; each 20
support has a peg 1 at its upper side which the hollow foot 2 of the
upon
cup i fits, as best seen in the sectional part of Figure 3. The peg 1 is fixed
to the conical seat k, the conical seat k and peg 1 are made by preference
separately from the supports h, and are fixed to the said supports by the screw
nut m; by means of the conical seat and peg described, and the hollow foot s
of the egg cup for fitting thereon, the egg cups are prevented from falling
from the platforms or supports. Instead of two platforms or supports for
carrying the egg cups three, four, or other required number may be used.
At the side of the body a of the egg boiler is a minute or sand glass n for
indicating the time for boiling the eggs. The said glass n is carried by the
metal frame p, the said frame being capable of rotating on the pin or centre
fixed to the side of the body a. The frame

plater to the required extent in the frame a fresh sand or minute glass may

be readily replaced and fixed in the said frame should the minute or sand
glass be broken.
When the time for boiling the eggs is required to be indi-
cated the frame of the minute or sand glass n is turned by its handle p² so as
to invert the said glass n; the sand in the upper bulb of the glass thereby
5 passes to the lower bulb and indicates the time necessary for boiling the eggs,
as is well understood.
Although we find it convenient to place the minute or sand glass at
the side of the body of the egg boiler, as represented in the accompanying
Drawing, yet we do not limit ourselves to that position, as the said sand
or minute glass may be placed at any other convenient part of the egg
boiler.
By constructing egg boilers for the table according to our Invention they
are made to carry the egg cups, and are furnished with an indicator by which
the time for boiling the eggs can be ascertained.
Ilaving now described the nature of our Invention, and the manner in
which the same is to be performed, we wish it to be understood that we do
not limit ourselves to the precise details herein described and illustrated, as
the same may be varied without departing from the nature of our Invention;
but we claim as our Invention of improvements in or additions to egg boilers
for the table,-
Firstly, combining with the said egg boilers a series of radial platforms o
supports for carrying the egg cups, substantially in the manner herein-before
described and illustrated in the accompanying Drawing.
Secondly, combining with the said egg boilers a sand or minute glass fo
indicating the time for boiling the eggs, substantially in the manner herein
before described and illustrated in the accompanying Drawing.
In witness whereof, we, the said Benjamin Barrett and Henry Ma
kenzie, have hereunto set our hands and seals, this Eleventh day
November, in the year of our Lord One thousand eight hundred an
