Mather and Platt, of Salford, in the County of Lancaster, Engineer,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR MEASURING
LIQUIDS, FOR OBTAINING MOTIVE POWER, AND FOR EXHAUSTING AND FORCING

by Emile Eugene Pierre Clausolles, of Barcelona, Spain, Doctor of
Medicine.
Scaled the 29th December 1874, and dated the 12th November 1874.
PROVISIONAL SPECIFICATION left by the said William Mather at the
Office of the Commissioners of Patents, with his Petition, on the
: 12th November 1874.
I, WILLIAM MATHER, of the Firm of Messieurs Mather and Platt, of
5 Salford, in the County of Lancaster, Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
MEASURING LIQUIDS, FOR OBTAINING MOTIVE. POWER, AND FOR EXHAUSTING AND

page_text: FORCING AIR AND OTHER GASES AND FLUIDS," being a communication to me
from abroad by Emile Eugene Pierre Clausolles, of Barcelona, Spain,
Doctor of Medicine, to be as follows:-
:―
This improved apparatus consists of three or other convenient number
of metallic or other bellows formed of annular discs or plates with
leather or other joints, which are in communication with the ingress
and egress passages formed in the foundation plate of a box, the bellows
are united by the arms of a compound lever which vibrates in a spherical
recess in a fixed stand, and the lower end of the axis of this compound
lever communicates a rotary motion to a circular valve which opens and
closes the ingress and egress ports, and the upper end of the axis gives
motion to the index dials, or to a rotary shaft for transmitting power, or
to pumps.
The metallic or other bellows are made to contain a certain fixed
quantity of liquid, and the pressure on the liquid to be measured causes
the said bellows to expand and collapse alternately.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Mather in the Great Seal Patent Office
on the 10th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MATHER, of the Firm of Messieurs Mather and Platt, of Salford, in the
County of Lancaster, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of November, in the year of our
Lord One thousand cight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Mather, Her special licence
that I, the said William Mather, my executors, administrators, and
assigns, or such others as I, the said William Mather, my 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

with the three-way valve shewn detached in Figs. 3, 4, 5, and 6. The
seating c of the valve is shewn in Figs. 3 and 4; the larger ports
marked care in communication with the bellows a, and the smaller.
ports c² communicate with the egress passage 62: The valve d shewn in
Figs. 5 and 6 fits on the seating c, and is kept central by the stud
projecting from the valve fitting in a hole in the seating; this valve has
a port d' which forms the communication between the ingress passage
and the bellows and the port d² which communicates with the egress
passage b³. At the upper end of each bellows is a socket to receive the
balls at the ends of the arms of the compound lever e which serves to
unite all the bellows a, a; the arms of this compound lever are fixed in
the centre ball e¹ which vibrates in a spherical recess in the fixed stand
screwed to the valve seating c, or to the foundation plate b. The ball e¹
is fixed to the axle g at the lower end of which is a recess fitting on a
pin in the valve d; the upper end of the axle g takes into the lever /
which is fixed on the axle of a worm which communicates motion to the
ordinary index dials. The whole apparatus is enclosed by the case i
which is secured to the foundation plate b.
The mode of operation is as follows:-The liquid to be measured is
supposed to be entering at 6', see Fig. 2, and when the liquid has filled
all the space in the box i it passes through the port d which is always
in communication with one of the bellows; the first bellows are then
expanded, and in rising they impart by the compound lever e and
spindle a partial rotary motion to the valve d, which then admits the
liquid into the second bellows. When the first bellows are fully
expanded the second bellows continue to impart the rotary motion to
the valve which brings the port d² over the port c¹ which communicates
with the first bellows, the fluid from which is thus conveyed through the
ports c¹ and c² to the egress passage 62. As the second bellows continue;
to expand the third begin to receive their share of fluid, and when the
third are fully expanded the second begin to discharge, and so the
operations are repeated, the valve d continuing to rotate over the
seating c, and opening and closing the ports as required. When
the three bellows have been expanded in succession the spindle g will
have performed one revolution which is recorded on the usual index
dials, and as each bellows contain a certain fixed quantity of fluid it is
evident that the said quantities passing through the machine will be
measured and recorded.

page_text: When the apparatus is used for obtaining motive power the liquid or
fluid under pressure expands the bellows, and the upper part of the
spindle in revolving imparts the requisite rotary motion to a driving
shaft; and when the apparatus is applied for exhausting and forcing air
and gases, power is applied to the end of the upright spindle g, thereby
actuating the bellows in succession, and thus exhausting or forcing a
constant current of air or gas.
Having thus stated the nature of my Invention and described the
manner of performing the same, I declare that I claim,—
First. The use of metallic or other bellows for measuring liquids, for
obtaining motive power, and for exhausting and forcing air and gases, as
shewn and described.
Secondly. Constructing bellows of thin discs of metal connected at
their edges by solder or otherwise as described.
And, Thirdly. The compound lever e and spindle g for connecting the
bellows and transmitting motion to the valve, and to the indicating dials,
or to or from a driving shaft, as shewn and described.
In witness whereof, I, the said William Mather, have hereto
set my hand and seal, this Eighth day of May, One thousand
eight hundred and seventy-five.
