IMPROVEMENTS IN GAS METERS
Year: 1860

page_text: LETTERS PATENT to Edwin Harrison and Joshua Scott, of Oldham, in
the County of Lancaster, Gas Meter Manufacturers, for the Invention
of "IMPROVEMENTS IN GAS METERS."
Sealed the 6th July 1860, and dated the 13th January 1860.
PROVISIONAL SPECIFICATION left by the said Edwin Harrison and
Joshua Scott at the Office of the Commissioners of Patents, with
their Petition, on the 13th January 1860.
We, EDWIN HARRISON and JOSHUA SCOTT, of Oldham, in the County of
Lancaster, Gas Meter Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN GAS METERS," to be as follows:-
We employ a spoon or feeder for supplying water from the cistern to the
interior of the meter, and give it motion by causing a cam or eccentric on the
upright shaft to act on an arm or lever on the spoon shaft, the spoon or feeder
supplying the water according to the speed of the upright shaft, a. pipe.com-*
municating with the cistern and the interior, in order to maintain a proper
level and prevent overflow. We also separate. the float from the water cistern
by means of a partition, thus rendering. the level of the water in the interior
perfectly independent of the water in the cistern; or we, modify the arrange-
ment by having no partition in the cistern, and maintain the proper level of
the interior by means of an overflow pipe.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edwin Harrison and Joshua Scott in the Great Seal Patent
'Office on the 12th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWIN
HARRISON and JOSHUA SCOTT, of Oldham, in the County of Lancaster, Gas
Meter Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of January, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edwin Harrison and Joshua Scott, Her special licence that
we, the said Edwin Harrison and Joshua Scott, our executors, administrators,
and assigns, or such others as we, the said Edwin Harrison and Joshua
Scott, our executors, 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, and Isle of Man, an Invention for "IMPROVEMENTS IN GAS METERS,"
upon the condition (amongst others) that we, the said Edwin Harrison and
Joshua Scott, our executors or administrators, by an instrument in writing
under our, or their, or one of our or their hands and seals, should particularly
describe and ascertain the nature of the said Invention, 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 we, the said Edwin Harrison and Joshua Scott,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained' in
and by the following statement (that is to say):-
-
We employ a spoon or feeder for supplying water from the cistern to the
interior of the meter, and give it motion by causing à cam or eccentric on the
upright shaft to act on an arm or lever on the spoon shaft, the spoon supplying
the water according to the speed of the upright shaft. There is a pipe com-
municating with the cistern and the interior, and also a hole above, so as to
maintain a proper level and prevent overflow.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is a back
view of the meter with the cover off, in order to shew the interior; Fig. 2, an

page_text: end view of the same with part of the side removed; Fig. 3, a detached
elevation of the upright shaft and eccentric; and Fig. 4, a plan of the eccentric
only.
The spoon is shewn at a on the spoon shaft 6, fixed to which is the arm or
lever c pressing against the rim of the eccentric d fixed upon the upright
shaft e, which, at each revolution, causes the spoon to move up and down and
supply water from the cistern. When water is supplied to the meter, its
proper level is obtained by the elbow pipe f, and if the spoon should deliver
more water into the measuring capacity than is required, the proper level is
maintained by means of the overflow pipe g or hole h, or both combined if
desired. In the cistern there is a partition i extending from the top to the
bottom, and also to the door, which partition has at the bottom an aperture k,
to allow any excess of water in the measuring capacity to return into the
cistern containing the spoon. We also, when desired, separate the float from
the water cistern by means of a partition, thus rendering the level of the
water in the interior perfectly independent of the water in the cistern.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, wo desire it to be distinctly understood
that we do not confine ourselves to the precise details berein set forth; but
we claim, the eccentric and lever for giving motion to the spoon shaft and
spoon, with the partition and passages of communication for maintaining a
proper level of the water in the cistern and the interior, as herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Joshua Scott, for and on behalf of myself
and the said Edwin Harrison, have hereunto set my hand and seal,
this Tenth day of July, in the year of our Lord One thousand eight
hundred and sixty.
Signed, sealed, and delivered by the
within-named Joshua Scott, in
the presence of
E. J. HUGHES, Patent Agent,
Manchester.
