PROVISIONAL SPECIFICATION.
An Improved Apparatus for Measuring Liquids and Gases.
CHARLES THOMAS BULLOUGH 3 Ballater Road Brixton Surrey Engineer do
hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved apparatus for measuring liquids
(hot or cold) but it may be applied to gases. It consists of a double-acting
cylinder fitted with a leather packed piston & gland, although two single acting
cylinders could be used & then the gland would not be required. If used for hot
liquids, it would be fitted with metallic packings. The piston rod in the case of the
double-acting cylinder would be hollow in its length in which slides an hinged piece
attached to a link at one end & the other end is hinged to the slide valve & so
imparts a portion of the pistons travel to it. The cylinder has the necessary
ports & passages which are parallel to its bore, the middle or exhaust port is
extended at its ends.
The slide is of the ordinary D type with a port at each end of its exhaust
chamber which communicates with a small cylinder upon the top of the slide valve
which is fitted as the before-mentioned measuring cylinder. The piston rod of
the slide cylinder may be extended at both sides so that it will fit between two
parallel faces in the interior of the casing but it may engage into a T slot on one
side only.
In applying this invention for gases bellows would be used after the usual manner
of dry gas meters.
The action of this apparatus is as follows,
The piston of the measuring cylinder which is attached to the hollow piston
rod travels from one end of the measuring cylinder almost to the other, when the
hinged piece touches at the end of the hollow piston rod & so imparts the necessary
motion to the slide valve which opens one of the ports in the valve face and causes
the slide cylinder to move to the side and so reverses the action.
This meter has only one slide and one face the action of which is rectilenear so
that it will keep the faces in better order than if it moved in one direction only
and both cylinders use one common exhaust.
The slide face may be cylindrical the out side of the slide cylinder being turned
a fit so that it can be made to revolve backwards and forwards through a lever,
rifle or other means. The valve controlling the measuring cylinder ports would have
a slight spring behind it so as to keep it tight, the two ports in the slide cylinder
would come alternately opposite ports in the slide casing and so work the cylinder
and slide over the measuring ports.

COMPLETE SPECIFICATION.
An Improved Apparatus for Measuring Liquids and Gases.
CHARLES THOMAS BULLOUGH Engineer 3 Ballater Road Brixton Surrey do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings:-
Fig. 1 longitudinal section of my improved apparatus.

page_text: Fig. 2 transverse section through the centre.
Fig. 3 is a plan of the apparatus showing the inlet, outlet, and index.
Fig. 4 show the valve and slide faces.
This invention has reference to an improved apparatus for measuring liquids
(hot or cold) but it may be applied to gases. It consists of a double acting
cylinder fitted with leather packed piston and gland but I have shown two single
acting ones as preferable. If used for hot liquids it would be fitted with metallic
packings. The cylinder has the necessary ports H and K which are parallel to its
bore the middle or exhaust port J is extended at it ends.
The slide B is of the ordinary D type with ports L and N at each end of the
exhaust chamber M which communicate with the small cylinder B upon the top
of the slide valve which is fitted as the before mentioned measuring cylinders.
The piston rod E engages in a T slot on the side of the casing.
In applying this invention to gases bellows would be used, after the usual manner
of dry gas meters.
The action of this apparatus is as follows,
The piston C of the measuring cylinder A travels from one end of the measuring
cylinder almost to the other when it touches the slide cylinder B and so imparts
the necessary motion to the slide valve which opens one of the ports L or N and
causes the slide cylinder to move which opens alternately the ports of the measuring
cylinder H and K.
The receptical F for the index has on the bottom a piece fitted so as to impart
a pressure upon the top of the slide to keep it on its face. The necessary motion
for actuating the index is purposely omitted to avoid complication. This meter
has only one slide and one face, the action of which is rectilenear so that it will
keep the faces in better order than if it moved in one direction only both cylinders
use one common exhaust J. The slide face may be cylindrical the outside of the
slide cylinder being turned to fit so that it can be made to move back wards or
forwards through a lever, rifle, or other means. The valve controlling the
measuring cylinder ports would have a slight spring behind it, so as to keep it
tight. The two ports in the slide cylinder would come alternately opposite ports
in the slide casing and so work the cylinder and slide over the measuring ports.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. An improved apparatus or meter constructed and arranged in manner sub-
stantially, as shown in the drawings and as herein-before described.
2. A slide moving rectilenear and thereby actuating itself and controlling another
cylinder or cylinders.
3. The slide to be made cylindrical and to have part rotary motion and part
reciprocatory.
