page_text: LETTERS PATENT to Robert Greon Grimes, of No. 130, Saint George
Street, in the Parish of Saint George in the East, in the County of
Middlesex, Public House Bar Fitter, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION AND ARRANGEMENT OF THE WORKS AND CASES OF
BEER ENGINES."
Sealed the 30th May 1865, in pursuance of an Order of the Lord Chancellor,
PROVISIONAL SPECIFICATION left by the said Robert Green Grimes,
at the Office of the Commissioners of Patents, with his Petition,
on the 17th November 1861.
I, ROBERT GREEN GRIMES, of No. 130, Saint George Street, in the Parish
of Saint George in the East, in the County of Middlesex, Public House Bar
Fitter, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION AND ARRANGEMENT OF THE WORKS AND CASES OF BEER
ENGINES," to be as follows, and shewn by accompanying Drawings:-
I make, arrange, and fit in their cases the works of beer engines so as to
render them self-fixing by means of their own connecting nuts and screws or
unions (see Figure 1 at a, b, c, d, and e; Figure 2 at a and b, and Figure 3
at e.) Portions of their cases are male moveable so as to present easy access
to their various parts, in order that they may be easily fixed or disconnected
(see Figure 1 at f, g, and n).
I provide for iceing or cooling liquors when within the pump cylinders of
the beer engines by the construction of cisterns in their cases, into which the
pump cylinders are to be fixed (see Figure 1 at 1, 2, and h³).

page_text: I also construct smaller cisterns within or in contact with the larger
cisterns for the purpose of cooling water (see Figure 1 at j). Ginger beer,
soda water, lemonade, or other articles may be placed in the cisterns for the
purpose of being iced or cooled. The cisterns may also be used for the
purpose of warming liquors when within the pump cylinders.
I also provide cocks and pipes connected with the larger and smaller
cisterns for the purpose of drawing the water therefrom or for conveying
steam or other heat thèreinto (see Figure 1 at 7 and m).
I make the bottoms of sinks of beer engines of tin, tinedir on, zinc, or
other metal or other hard substance, and form pot stands or gratings fixed
thereon (see Figure 1 at k).
I make projections to cover the backs of the sinks of the beer engines to
prevent splashings getting behind them (see Figure 1 at i).
SPECIFICATION in pursuance of the conditions of the Letters Patent
and of an Order of the Lord Chancellor, by the said Robert Green
Grimes in the Great Seal Patent Office on the 31st May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
GREEN GRIMES, of No. 130, Saint George Street, Saint George's in the East,
Public House Bar Fitter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Hor Letters
Patent, bearing date the Seventeenth day of November, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Robert Green Grimes, Her special licence that I, the said
Robert Green Grimes, my executors, administrators, and assigns, or such
others as I, the said Robert Green Grimes, my executor, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend within the United Kingdom
of Great Britain and Ireland, the Channel Islands, aud Isle of Man, an
Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF THE
WORKS AND CASES OF BEER ENGINES," upon the condition (amongst others)
that I, the said Robert Green Grimes, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention

page_text: and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Green Grimes, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement:-
This Invention has for its object improvements in the construction and
arrangement of the works and cases of beer engines, and consists in making
the works so as to render them self-fixing by means of their own nuts and
screws or unions. Portions of the case into which the works are fixed are
made moveable so as to present easy access to their various parts. The pump
cylinders are fixed to a plate of tined iron or other hard material which is
made to serve the purpose of a bottom for a chest or box formed in the case
for the purpose of containing ice to cool beer or other liquid when passing
through the
pump cylinders. A small is placed inside or in contact with
the chest or box, into which clear water may be placed and cooled and
drawn off as required by means of a pipe and cock connected therewith. The
water caused by the melting of the ice may also be drawn off by means of
another pipe and cock and hot water; air or steam may be injected to the
chest or box by means of a pipe connected to a screw on the nose of the cock
so as to warm beer or other liquid when passing through the pump cylinders,
and to fix projections to the bottoms of the sinks of beer engines for measures
to stand upon.
And in order that my Invention may be most fully understood and readily
put into practice, I will now proceed to describe the accompanying Drawings.
Figures 1, 2, & 3 shew transverse vertical sections of the parts of a beer
engine as constructed and arranged agreeably to my Invention. a, a, in
Figures 1 and 2, shews double action nuts and screws by means of which the
handle is fixed to the stem of the lever; b, b, in Figures 1 and 2 shows the
means by which the handle, lover, axle bearings and sling (usually termed the
gearing of the engine) is fixed. The whole of the gearing is connected
together and passed into the case through the front door or fall () when
opened, and the handle lever and part of the bearings pass through a hole in
the top of the case so far as the flange or stop will allow. The screw upon
the bearings is raised above the upper side of the top so that it may enter the
fly nut, which is passed over the handle and screwed down upon the top,
thereby fixing the whole of the gearing to the top of the case.
shews a fly nut and nut and screw to fix the spout and connect
c, in Figure 1
the pipe from

page_text: the pump cylinder to the tail of the spout; d, in Figure 1 shews a thumb-
screw pin to connect the sling to the piston rod of the pump; e, e, in Figures
1 and 3 shews the bottom screw of the pump cylinder passed through a plate
of tined iron or other hard material so far as the flange will allow, and the
bottom of the pump screwed on to the under side of the plate, thereby fixing
the pump cylinder to the plate. f, in Figure 1 shews the front door or fall
which opens and affords easy access to the interior of the case; g, in
Figure 1 shews a door or fall which opens at the back for the same purpose;
h1, h2, and h³, in Figure 1 shews the front, bottom, and back of the chest or
box formed in the case for the purpose of containing the ice required for
cooling the beer or other liquid when passing through the pumpcylinders for
cooling the clear water in the cistern and such other articles as the chest or
box will contain, and which it may be desireable to cool; 7, in Figure 1 shows a
moulding or other projection upon the front of the case to cover the back of
the sink so as to convey the splashings into the sink; j, in Figure 1 shews a
cistern formed in the chest or box for the purpose of cooling clear water;
k, in Figure 1 shews the bottom of the sink of the engine made of tined iron
or other hard substance with projections thereon to form a stand to prevent
the measures from standing in the slop in the sink; and m, in Figure 1
shews the pipes and cocks by which the melted ice may be drawn from the
chest or box and also the clear water from the cistern, and the screw shewn
on the nose of the cock is for the purpose of connecting a pipe thereto
through which steam, hot air, or hot water may be passed into the chest or
box in order to warm beer or other liquor when passing through the pump
cylinders, although the section shews only one pipe and cock, there will be
two, one at each end of the engine under the sink; n, in Figure 1 shews a
door or fall below the sink, which may be opened in order to reach the
bottoms of the pump cylinders and other connecting unions; o, in Figure 1
shews a lid or cover to prevent the cold or heat escaping from the chest or
box in which the pump cylinders are placed.
In witness whereof, I, the said Robert Green Grimes, have hereunto set
my hand and seal, this Thirty-first day of May, in the year of cur
Lord One thousand eight hundred and sixty-five.
