Improvements in Valves for Stopping or Regulating the Flow of
Chemical and other Liquids.
CHARLES HENRY CLIFFORD RUDD Clonsden Hill Forest Hall Newcastle-
on-Tyne Chemical Plant Maker do hereby declare the nature of this invention
to be as follows:-
"Improvements in valves for stopping or regulating the flow of chemical and
other liquids."
The necessity of a safe servicable and reliable means for stopping or regulating
the flow of chemical and other liquids has been a want long felt by chemical
and kindred trades manufacturers. The hitherto method of ordinary cocks or
taps has been found to have so many drawbacks-such as plugs lifting and
allowing the liquids to squirt or fly out causing accidents and loss, also the rapid
wear and tear by friction on the soft metals making them to become leaky and
worn out at a very short interval of time is a clear proof of the unreliability
of such means.
Attempts to remedy the above named drawbacks and defects
have from time to time been made by the introduction of various forms of taps
and valves, but their construction has been so unsuitable that they could not be
adapted with any success to the purpose for which they were intended-their
liability to choke up, corrode, wear out quickly or become fixed being amongst the
defects whereby such inefficiency was caused-hence the great necessity for an
improvement.
My valve by its peculiar construction and materials is peculiarly well adapted
to the purpose referred to namely for use with chemical and other fluids.

materials.

as herein described with reference to the accompanying drawing made in lead
regulus or any other metal or materials more suitable.

Improvements in Valves for Stopping or Regulating the Flow of
Chemical and other Liquids.
CHARLES HENRY CLIFFORD RUDD, 204 Church Street, Walker-on-Tyne
Chemical Plant Maker, 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:-
The necessity of a safe servicable and reliable means for stopping or regulating
the flow of chemical and other liquids has been a want long felt by chemical and
other kindred trades manufacturers. The hitherto method of ordinary cocks or
taps has been found to have so many drawbacks such as plugs lifting and allowing
the liquid to squirt out causing accidents to attendants and loss of liquid, also the
rapid wear by friction on the soft metals generally employed causing them to
become leaky and worn out in a very short period of time affords proof sufficient
of the unreliability of such means. Attempts have from time to time been made to
remedy the aforenamed drawbacks and defects by the introduction of various
forms of taps and valves, but their construction has been so unsuitable that they
could not with success be adapted to the purpose for which they were intended,
their liability to choke up, corrode, wear out quickly or become fixed and
unworkable being amongst the defects whereby such inefficiency was caused-
hence the necessity for an improvement.
My valve by its peculiar construction is especially well adapted to the purpose
herein referred to—namely—stopping or regulating the flow of chemical and other
fluids.
In the drawing lodged with Provisional Specification,
Fig. 1 represents a transverse section of my valve. A is the body with combined
or loose valve seat. B is the cover and stuffing box combined, C is the gland to
same, D is a cover which fits on to top of gland C. The gland C is made in two
halves and when the cover D is removed C can be taken out and the stuffing box

spindle, F is the hand wheel or handle with boss piece fitted for actuating the
valve, G is the bridge piece or bridle into the boss way of which the boss of F
is fitted, H is a guide clamp which by slot or opening h. h. is fitted on spindle E,
I is a nut which is screwed on to spindle E and fits down into hollowed part of H
and holds the latter in position.
Fig. 2 is an end elevation of this form of my valve shewing an external
appearance of the aforenamed parts which are lettered correspondingly, also
shewing a ridge J on inner side of bridge piece G, the small slot h. a. in guide
clamp H fits on to ridge J.
Fig. 3 is an elevation (on an enlarged scale) of the top or head gearing of my
valve and shews on spindle E two flat sides K on to which guide clamp at
opening his fitted.
Fig. 4 is a representation in plan of the part A with all else removed.
The internal parts of my valve are made in lead regulus or any other suitable
metal or materials, the packing is india rubber or other such elastic durable
substance, the outer or actuating parts are made in iron, brass or other suitable
material.
Having described one form of my valve I further claim for other forms to
place the inlet or outlet branch or branches at any angle to the valve and seat
or at any angle to each other or to make them any more suitable shape otherwise
than shewn in the drawing lodged with Provisional Specification.
Further to
employ any other method of joints usually used such as spigot, socket, male or
female ends, screw couplings and plumbed joints instead of flanges as shewn.
The valve is opened or shut by operating the hand wheel or handle F with boss
piece rotating in boss way of bridge piece G, F's internal screw rotates on screw of
spindle E and causes the latter to rise or fall, the guide clamp H with the nut I
fitted down into it being fitted on to flat part K of spindle E cannot become loosed
and also having the ridge J projecting into it's small slot . a. a most important
point is secured namely that rotation of the valve & spindle is rendered impossible
thus securing a minimum of wear in all parts desirable of the soft metals generally
used.
Having now particularly described the nature of my said invention and the
manner in which the same is to be performed, I declare that what I claim is
Constructing all stop or regulating valves for use with chemical and other fluids
as herein described with reference to the drawings lodged with Provisional
Specification, made in lead regulus or other materials suitable.
