Draughtsman do hereby declare the nature of this invention to be as follows:-
This invention relates to the apparatus used for regulating the flow of water or
other fluids into steam boilers or other receptacles so that the level of the water
may be kept at any desired height within the boiler or the level of the water may
be raised or lowered at will.
The arrangement by which the above is carried out is by means of a double
beat or single faced valve operated on by means of a float attached to the long arm
of a bell-crank lever inside or in connection with a boiler or other receptacle.
The Float is arranged on a bell-crank lever which is balanced by a counterpoise
or spring in such a way that when the water level rises or falls the float rises and
falls with it.
A connecting link is attached by one end to the short arm of the bell-crank
lever the other end of the connecting link is attached to an adjustable piece or rod
this adjustable piece or rod is connected to the double beat or single faced valve
ov suitable means so that the distance between the short arm of the lever and the
double beat or single faced valves can be increased or decreased the valve seats
remaining stationary or the connecting link can be made to take the place of the
adjustable piece by putting the adjustable part on the link instead
of on a separate piece by increasing the distance between the double
beat or single faced valves and the short arm of the lever the long
arm of the lever to which is attached the float will be raised and the
water will be required to rise to a higher level before the float will come into
operation to close the valves and prevent the water or other fluids from passing
into the boiler and thus the water level will be raised or if the distance between
the double beat or single faced valves and the short arm of the lever be decreased
the long arm of the lever to which is attached the float will be lowered and the
water will not be required to rise so high before the float will come into operation
to close the valves and prevent the water or other fluids from passing into the
boiler thus the water level will be lowered.
Instead of using a double beat or single faced valve I may use a slide valve or
other form of valve operated on as described above.

Draughtsman 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:-
This invention relates to improvements in the apparatus used for regulating
the flow of water or other fluids into steam boilers or other receptacles whereby
the water level may be raised or lowered at will.
The arrangement by which the above is carried out is shown by the drawing
annexed.
With reference to the annexed drawing Figs. 1 to 4 show sectional details of the
valve while Figs. 5 & 6 show one method of attaching the same to a water tube
boiler. The apparatus may be attached in a similar manner to any other form of
boiler or receptacle.
Fig. 1 is a sectional elevation. a is the valve case or chest having-one. or: two
seats b. c. which are covered by the valve lids d. e. if two valve seats are used the
valve lids d. e. are connected together and form a double beat or balanced valve
one side of the valve lid d. is connected to the part f. by means
of ribs or feathers g. to this part f. the spindle h. is attached by
means of a screw or other suitable arrangement so as to enable the end of the
Float lever to be brought nearer to or removed further from the valve lid d.
thereby raising or lowering the float k. thus causing the water level to be raised
or lowered, on one side of the valve lid e. is a square or other shaped part r. which
works freely in the hollow spindle 7. which has a corresponding part in it so that
when the spindle 7. is rotated by the wheel m. or other appliance the part f. is
caused also to rotate and as the spindle h. is prevented from turning the spindle h.
will be drawn in or out of the part f. thus increasing or decreasing the length
between the float lever j. and the valve lid d. thereby raising or lowering the
float . The nut n. which works on the spindle 7. is prevented from rotating by a
guide o. which may be marked thus indicating the amount of rise or fall of the
float . The inlet of the valve is at p. and the outlet at q. or q. may be made the
inlet and 2. the outlet.
Fig. 2 is a cross section on line S. T. which shows the part f. and the ribs or
feathers g.
Fig. 3 is a cross section on the line U. V. showing the hollow spindle 7. and the
square on the valve e.
Fig. 4 is a cross section on the line W. X. showing the nut n. and guide o.
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
I. In the apparatus used for regulating the flow of water into boilers or other
receptacles a means of altering the level of the water within a boiler or other
receptacle by suitable means from the outside.
II. In the apparatus used for regulating the flow of water into boilers &c. a
means of connecting a single or double beat valve to a float contained in a boiler
or other receptacle as shown in Figs. 1; 5, & 6.
III. A means of altering the position of the float in relation to the valve or
valves contained in the valve case by, rotating a spindle, connected to the valve
or valves in such a way that the valve or valves can be rotated without interfering

page_text: with the free motion of the valve or valves in a direction parallel to the axis of the
valve or valves as shown in Fig. 1.
IV. A means of attaching the link or rod to the valve or valves in such a way
that while the valve or valves are rotated the link or rod is prevented rotating
thus causing the link or rod to be drawn nearer to or moved further from the valve
or valves by the link or rod being screwed into the end of the valve or valves or
the link may be screwed inside and the end attached to the valve or valves screwed
on the outside thus effecting the same purpose.
V. A means of shortening or lengthening the distance between the valve or
valves d. e. and the Float lever j.
