Improvements relating to Stop Valves.
We, CHARLIE LIONEL TEMPLER, Associate Member of the Institute of Civil
Engineers, Allesley, King Charles Road, Surbiton, in the County of Surrey and
JAMES PHILIP RANOE, of 9 Prospect Place, Long Ditton, in the county
aforesaid, Engineer, do hereby declare the nature of this invention to be as
follows:-
Our invention pertains to improved means for the actuation of double check
stop valves whereby the steam or other fluid is enabled to obtain a straight
through passage and the valves are actuated in a positive manner.
In carrying our invention into effect when constructing a double check stop
valve in accordance with our present invention, we provide two beat or other
valves vertically disposed, which we connect together by means of a valve rod and
provide with seats in the valve casing, the one upon the admission and the other
upon the exit side thereof. This valve rod we operate by means of a transverse
vibrating arm which we pivot upon one side of the casing, and we provide pins or
pivots secured to such rod for working within a sliding or bearing block or blocks
that is or are allowed a slight reciprocation within a longitudinal slot or slots
formed in the vibrating arm in such a manner that upon the actuation of the
vibrating arm a vertical notion is imparted to the valve rod; the sliding or
bearing block or blocks allowing for the slight lateral component of the curvature
of the vibration at that point of connection.
We communicate motion to the vibrating arm by means of a screwed spindle
disposed in a parallel direction to the valve rod, which spindle we arrange within
a side casing preferably formed integral with or separated by a joint from the
valve casing proper, and we provide upon such screwed spindle a loose nut which
travels to and fro upon its rotation from without by incans of a handwheel
attached to the extremity of the spindle for this purpose. A pin or pins upon this
travelling nut works or work within a swivelling or sliding block or blocks which
is or are embraced by the forked end or ends of the vibrating arm, and upon the
operation of the screw the travelling nut causes the movement of the forked end
of the arm and a vertical motion is thereby imparted to the valve rod depending
for its direction upon the direction of rotation of the handwheel, whereby the
valves are opened or closed in a positive manner.
In another manner of carrying our invention into effect we provide for the
actuation of the valve rod by means of a screwed spindle disposed transversely
thereto, such screwed spindle being provided with a bearing upon one side of the
casing and at the other side with a stuffing box; and has formed thereupon a right
and left handed screw upon either side of the valve rod which may be bifurcated
or otherwise formed to clear it. The valve rod and valves are actuated by means
of nuts or screwed collars which are caused to travel in opposite directions upon
the rotation of the screwed spindle, the lateral motion of such nuts or collars
communicating a vertical motion to the valve rod by means of connecting links,
secured therefrom to the nuts upon the spindle in such a manner that on receding
the nuts or collars cause a corresponding downward motion of the rod and close the
valves, while the valves are lifted when motion is imparted to the screw in the
opposite direction.

page_text: We do not limit our invention to the particular mechanical details herein
described for communicating motion from the travelling nut, nuts or collars upon
the operating screwed spindle to the vibrating arm or to the valve rod, but
modify the same to meet exigencies of manufacture or the requirements of any
particular case.

Improvements relating to Stop Valves.
We CHARLIE LIONEL TEMPLER, A.M.I.C.E. Allesley King Charles Road
Surbiton in the County of Surrey and JAMES PHILIP RANOE, Engineer
9 Prospect Place, Long Ditton in the county aforesaid 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 :-
Our invention pertains to improved means for the actuation of double check
stop valves whereby the steam or other fluid is enabled to obtain a straight through
passage and the valves are actuated in a positive manner.
Fig. I is a section elevating following axial lines of spindle of straight through
valve.
Fig. II ditto of an angle way valve.
Similar letters of reference refer to like parts.
In carrying our invention into effect when constructing a double check stop
valve in accordance with our present invention, referring to Fig. I we provide two
beat or other valves A & B vertically disposed which are connected together by
means of a valve rod C which rod is free to move in valve B and has considerable
vertical play in valve A.
on the
The seatings for the two valves are provided in the casing, one
admission and the other on the exit side thereof. The valve rod C. we operate
by means of a transverse vibrating lever D. which we pivot on one side of the
casing to the eye holt E.
The rod C. also has a block or blocks F. sliding in a slot or slots G, which
allow a slight reciprocation within the slot or slots G, the block or blocks F being
pivoted by pins or pivots to the vibrating lever D. and, sliding in the slot or
slots G allow for the slight lateral component of curvature at that point of
connection, thus keeping the valve rod central,
We communicate motion to the vibrating lever shewn in plan Fig. 1^ D. and
also in elevation in Fig. 1. D. by means of a screwed spindle H. placed in a
parallel direction to the valve rod C. which spindle we arrange within a side
casing integral with or preferably separated by a joint from the valve casing
proper; and we provide on such screwed spindle a loose nut or nuts which travel
to and fro upon its rotation from without by means of the hand wheel J. attached
to the extremity of the spindle for this purpose.
The nut or nuts 1. are flanged so as to be embraced by the forked end or ends of
the vibrating lever D. or pin or pins upon the travelling nut or nuts work or works
within a sliding or swivelling block or blocks, which is or are embraced by the
forked end or ends of the vibrating lever D. and upon turning the screw the
nut or nuts 1. raise or lower the vibrating lever D, thus giving a vertical motion
to the valve rod C. whereby the valves A. & B. are opened and closed in a
positive manner.

page_text: The action of the valve is as follows. Assuming a valve to be fixed as an
engine stop valve. The flange K is fixed on to the boiler or steam side of the
engine and the flange L. to the engine side.
Now in opening the valve the handwheel J. is turned and the valve B. opens
a little until the top of valve rod C. bears against the valve A. where there is
considerable vertical clearance and then continuing the turning of the wheel both
valves open up together. Now to close the valve the handwheel J. is turned to
give a downward motion to the valve rod C. and the valve A. having the clearance
above mentioned closes, first, by the fluid pressure alone, leaving the valve B.
still open a little, and then, in continuing the turning of the hand wheel the
valve B. is closed; the two valves being independent when closed, valve A. being
held tight by fluid pressure, and valve B. being screwed down tight by the hand
wheel.
The drain cock which is fixed to the hole M. is for the purpose of draining
away any possible leakage which might pass the valve A. when valve A. is
closed.
Fig. 2. represents another manner of carrying our invention into effect.
The two beat or other valves A. & B. which are connected by means of a valve
rod C. which is either solid with the valve B. or separated by suitable means,
which rod has considerable vertical play in valve A. The seatings for the valves
are provided in the casing the same as aforesaid mentioned in Fig. I.
The valves are opened and closed by the direct action of the screw H. which
is fixed to valve B. either free to move as shewn in drawing Fig. 2 with a little
play, or fixed solid to the valve B.
On turning the screw H. by means of a handwheel, the valves are opened and
closed in a positive manner; the two valves as in Fig. 1. being independent when
closed, valve A. being held tight by fluid pressure, and valve B. screwed down
tight by turning the screw H.
.
The action of the valve is as follows; Assuming these valves to be fixed on a
battery of boilers all of which are feeding one main steam pipe. The flange L.
Fig. 2. is fixed on the boiler and the flange K. coupled up to the main steam
pipe; now supposing it was desirous for a man to enter one of the boilers for the
purpose of cleaning or repairing it, the valve B. would be closed by the hand-
wheel, and the valve A. closed by the fluid pressure which is on the main steam
pipe, the drain pipe fixed at M. between the two valves being left open.
The valve A. being closed by the fluid pressure from the main steam pipe,
this valve closing before the valve B. by reason of the considerable play on
the valve rod and after A. has been closed by fluid pressure the valve B. is
screwed down tight by the screw E. which is turned by a hand wheel.
The two valves when closed being independent and forming a double check, the
drain which is fixed to the hole M. is opened; to allow for any possible leakage
which may pass the valve A. to escape, thus securing absolute safety to anyone
entering the boiler.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is
No. 1. In double check valves; an arrangement and apparatus constructed and
operated substantially as described and for the purpose specified.
No. 2. The combination of two valves contained in the same casing, connected
by a valve rod, but yet, free to close independently of each other. One valve
being closed by the fluid pressure alone; the other being closed by turning the
band wheel.
No. 3. In double check valves, the combination of two valves contained in the
ame casing, one valve being closed by fluid pressure alone, and the other by the
handwheel, with a drain cock fixed in the valve casing between the two valves, in

page_text: communication with the atmosphere or condenser substantially as described and
for the purpose specified.
