page_text: LETTERS PATENT to Benjamin Joshua Grimes, of No. 170, Mile End Road,
and Lionel Dove, of No. 32, Tollett Street, Mile End Road, both in the Parish
of Mile End Old Town, in the County of Middlesex, for an Invention of "AN
IMPROVED APPARATUS FOR HEATING WATER, MULLING BEER, AND OTHER
LIQUORS FOR PUBLIC HOUSES AND GENERAL DOMESTIC PURPOSES BY MEANS
OF GAS OR OIL BURNERS."
PROVISIONAL SPECIFICATION left by the said Benjamin Joshua Grimes
and Lionel Dove at the Office of the Commissioners of Patents on the
27th November 1880.
BENJAMIN JOSHUA GRIMES, of No. 170, Mile End Road, and LIONEL DOVE, of
No. 32, Tollett Street, Mile End Road, both in the Parish of Mile End Old Town,
in the County of Middlesex. "AN IMPROVED APPARATUS FOR HEATING WATER,
MULLING BEER, AND OTHER LIQUORS FOR PUBLIC HOUSES AND GENERAL DOMESTIC
PURPOSES BY MEANS OF GAS OR OIL BURNERS."
The water is heated by gas or oil burners placed under the concave plates which
have a very small water space, as shewn at Figures 1 and 2 in Drawing annexed.
Figure 3 shews a hollow cylinder with a small water space between the inside
and outside casing, and is connected to the concave plates by a tube, as shewn at
Figure 4.
Figure 5 shews a pipe through which the cold water enters the cylinder,
Figure 3, and flows down the tube, Figure 4, into the bottom concave plates,
Figures 1, and from thence up the tubes, Figures 6, into the concave plate, Figure 2,
and passes out hot at the pipe shewn at Figure 7 into the urn or muller, as shewn
at Figure 8, and returns through the pipe shewn at Figure 9 into the heater again,
as shewn at Figure 5.
Figure 10 shews a pipe which is inserted between the inside and outside casing
of the urn or muller, to allow the hot water to be drawn off at the cock shewn at
Figure 11.
.
Figure 12 shews a pipe joined to the cock, Figure 13, so as to draw off the beer
from the muller, as shewn at Figure 14, after being warmed.
Figure 15 shews an expansion or exhaust pipe to prevent pressure upon the
muller.
The urn or muller is formed as a vase with an inside and outside casing, so as to
allow free circulation of the hot water; it can also be made in other designs for
keeping hot tea, coffee, wine, or other liquors, and for sausages and potatoes.

Office on the 27th May 1881.
BENJAMIN JOSHUA GRIMES, of Number 170, Mile End Road, and LIONEL DOVE,
of Number 32, Tollett Street, Mile End, both in the Parish of Mile End Old Town,
in the County of Middlesex, Engineers. "AN IMPROVED APPARATUS FOR HEATING
WATER, MULLING BEER, AND OTHER LIQUORS FOR PUBLIC HOUSES AND GENERAL
DOMESTIC PURPOSES BY MEANS OF GAS OR OIL BURNERS."
The illustration in the accompanying Sheet of Drawings shews a vertical sectional
elevational view of our apparatus as applied under the first mentioned head in the
title of our said Invention. The water is heated by means of gas or oil burners
placed under concave plates A, A³, and B, forming very shallow water spaces; C is
a hollow cylinder with a small water space between the inside and outside casing,
and is connected to the bottom water space A by the tube D. The cold water
enters the cylindrical vessel C through the pipe E, flows down the tube D into the
bottom water space A, and from thence up the tubes F into the upper water
spaces A and B, and passes out (heated) therefrom up the pipe G into the casing or
jacket of the muller H, whence it is returned to the heater again by a connection
made with the inlet pipe E.
The muller or urn is formed by preference of vase shape with inner and outer
casing forming a jacketting or space, so as to allow of free circulation of the hot
water, which is drawn off when required through the pipe J with cock K. The
contents of the muller-proper, that is to say, the interior vessel N, are drawn off
through the pipe L fitted with cock M. In order to provide against undue
pressure upon the muller, an expansion or relief pipe O is fitted to the apparatus
as shewn, and the return hot water passing through the pipe I may, as shewn in
the Drawing, instead of passing direct back to the heater below, be led away for
use at another portion of the bar or other place where our apparatus may be
fitted up.
We prefer to make the whole of the water receiving vessels and circulating pipes
in connection with the heater portion of our apparatus of copper. The heater itself
is enclosed in a surrounding casing, as shewn in the accompanying Drawing, and is
provided with a flue pipe P, to allow of the escape of the products of combustion
arising from the gas or oil burners.
It will be evident that in addition to the vessel N being used for mulling,
warming, or if required, highly heating and keeping hot various liquors, both
alcaholic and non-alcaholic, it may also be utilized with advantage for keeping hot
various items of diet, such as sausages, potatoes, and other edibles requiring to be
kept hot. And we would wish it to be understood that though we have shewn
only one special application of the apparatus according to our said Invention, it
may be applied in connection with a variety of domestic and other requirements,
such as for generating rapidly and economically the hot water for baths, or for
generating vapor or steam.
We would also wish it to be understood that we do not confine ourselves to the
exact arrangement shewn in the accompanying Sheet of Drawings as regards the
relative positions of the water inlet and outlet, as these may be varied without

page_text: departing from the nature of our Invention, substantially as herein described and
shewn in the accompanying Sheet of Drawings.
In witness whereof, we, the said Benjamin Joshua Grimes and Lionel Dove,
have hereunto set our hands and seals, this Twenty sixth day of May,
in the year of our Lord One thousand eight hundred and eighty one.
