IMPROVEMENTS IN VALVES FOR CISTERNS AND BOILERS
Year: 1884

page_text: I DAVID REGINALD ASHTON of 10 Avenue Road Clapton London, E. in the
County of Middlesex Brass Finisher do hereby declare the nature of my Invention
for IMPROVEMENTS IN VALVES FOR CISTERNS AND BOILERS to be as follows:-
A Valve the outlet of which is controlled by a cap, the interior of cap having
a seating of India Rubber or other suitable material which is secured in its position
by a ring or collar of any convenient depth the upper portion screwing into
the cap.
The cap is actuated by a lever pivoted to a carrier one end of lever having a ball
or float by reversing the lever and substituting a weight the Valve is suitable for
Steam purposes as an escape Valve.
My Invention relates to improvements in Valves for Cisterns and Boilers.
In carrying out my invention I apply it as a ball valve for controlling the flow
of water or other fluids, the inlet may be in any position, the stoppage or control is
effected at the outlet by a cap, in the interior of the cap is a seating or washer
made of India Rubber or other suitable material, the washer is secured in its
position by a ring or collar of any convenient depth the upper portion screwing into
the cap, the ring or collar also acts as a guide.
The cap is actuated by a lever pivoted upon a carrier one end of the lever is
pivoted to the cap the other end of the lever is connected to a ball or float, the
rising of the ball or float presses the cap on to the mouth of the outlet and prevents
egress of the water or fluid.
By pivoting the lever the reverse way, one end pivoted to the carrier it answers
the purpose of an escape Valve for Steam, Hot Water, fluids and compressed air, it
can be set to blow off at any given pressure by adjusting the position of a weight
hanging on to the lever which may be notched and marked to indicate the position
of the weight, the ring or collar which secures the washer and at the same time
acts as a guide may be perforated for the purpose of giving vent to the escape of
fluids.

page_text: Figure, 2, the principle is precisely the same and the same references to the
parts with the exception that H the ball or float is dispensed with and a weight, J,
substituted.
Figure 3 shows the underside of the ring or collar, E as applied to figure, 1.
Figure 4 shews the underside of ring or collar as applied to figure 2 as also vent
boles on the exterior of the collar.
Having described the nature of my Invention and the manner of performing
the same I declare that what I claim as my Invention to be protected is a cap
working on the exterior of the outlet combined with the ring or collar for securing
the washer or seating and the general arrangement of pivoting the lever for the
purpose substantially as set forth in this specification.

page_text: I DAVID REGINALD ASHTON of No 10 Avenue Road Clapton E in the County of
Middlesex do hereby declare the nature of my Invention for LMPROVEMENTS IN
VALVES FOR CISTERNS AND BOILERS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My Invention relates to Improvements in Valves for Cisterns and Boilers, in
carrying out my Invention as illustrated by drawings filed with my provisional
specification and figure 1 thereon I apply it as a Ball Valve for controlling the flow
of water or other fluids the inlet may be at the bottom as shewn in figure 2 or at
the side at right angles with the outlet as shewn figure 1 A is the inlet and B the
outlet, the stoppage or control is effected by a cap C, in the interior of the cap is
seating or a washer D made of India Rubber or other suitable material, the washer
is secured in its position by a ring or collar E of any convenient depth the upper
portion screwing into the cap the ring or collar also acts as a guide The cap is
actuated by a lever F pivoted upon a carrier G one end of the lever is pivoted to
the cap the other end of the lever is connected to a ball or float H the rising of the
ball or float presses the cap on to the mouth of the outlet and prevents egress of
the water or fluid.
By pivoting the lever the reverse way as shewn in figure 2 viz; one end
pivoted to the carrier it answers the purpose of an escape valve for Steam, Hot
Water, fluids or compressed air and can be set to flow off at any given pressure by
adjusting the position of a weight J hanging on the lever which may be notched
and marked to indicate the position of the weight, in figure 2 the ring or collar E
may be perforated at its lower extremity to give increased vent or egress.
Figure 3 shews the underside of the ring or collar as made for figure 1.
Figure 4 shews the underside of the ring or collar as made for figure 2.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
In a Valve for a Cistern or boiler the cap combined with the ring or collar for
securing the washer and seating substantially as shewn and described.
(2.) In a Valve for a Cistern or boiler the general arrangement of pivoting the
lever for the purpose as set forth and shewn on the drawings.
