PROVISIONAL SPECIFICATION.
Improvements in Valves for Tar. Ammoniacal Liquor, and other
Liquids.
I, FREDERICK SOUTHWELL CRIPPS of 9 High Street, in the Town of
Sutton, in the County of Surrey, Civil and Mechanical Engineer, do hereby
declare the nature of this invention to be as follows:-
The valve is so constructed as to admit of its being placed within contracted or
confined spaces; the distance from "outside to outside" of flanges measured along
its axis is not more than three inches, instead of eleven or twelve inches as in all
valves hitherto used for similar purposes and having the same bore, or diameter of
open way.
The valve is so constructed that the usual springs, wedges, & other devices for
pressing the slide up to its face, are rendered unnecessary. All the working parts
are protected from contact with tar, ammoniacal liquor and other liquors passing
through the valve.
In order to render the nature of my invention clear I append a sheet of
illustrative drawings, of which
Fig. 1 is an elevation with one of the side flanges removed, exposing the slide
and spindle to view.
Fig. 2 is a vertical section through center of valve.
Fig. 3 is a side elevation or outside view.
Fig. 4 is a sectional plan through center of valve-slide.
Fig. 5 is an outside plan.
The body of the valve consists essentially of three pieces, viz. a center casting
or distance piece A, and two side castings or flanges B and C. The faces of the
distance piece and the flanges are planed or faced to make sound joints. The
slide D, works against the planed faces of B and C, and within the distance
piece A. It is faced so as to work easily up and down in contact with and between
the parallel faces of B and C. The slide is actuated by the screwed spindle E,
which has a right and left handed thread, the former working through the flanged
nut F. at the top of the distance piece A. and the latter entering the body of the
slide D. into which it is screwed. When the position of the slide is determined the
lock nut G. is screwed tight down to prevent any possible leakage.
The valve is prepared for bolting to flanges of adjoining pipes &c. in such a
way as to make them perfectly solid with the valve and avoid springing same.
Dated this Twentieth day of September 1893.

COMPLETE SPECIFICATION.
Improvements in Valves for Tar, Ammoniacal Liquor, and other
Liquids.
I, FREDERICK SOUTHWELL CRIPPS, of 9, High Street, in the Town of
Sutton, in the County of Surrey, Civil and Mechanical Engineer, 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 valve is so constructed as to admit of its being placed within contracted or

page_text: confined spaces; the distance from "outside to outside" of flanges measured along
its axis is not more than three inches, instead of eleven or twelve inches as in all
valves hitherto used for similar purposes and having the same bore or diameter of
open-way.
The valve is so constructed that the usual springs, wedges, and other devices for
pressing the slide up to its face, are rendered unnecessary. All the working parts
are protected from contact with tar, ammoniacal liquor or other liquids passing
through the valve.
In order to render the nature of my invention clear, I refer in the following
description to the sheet of illustrative drawings left with the Provisional
Specification, and of which
Fig. 1. is an elevation with one of the side flanges removed, exposing the slide
and spindle to view.
Fig. 2. is a vertical section through centre of valve.
Fig. 3. is a side elevation or outside view.
Fig. 4. is a sectional plan through centre of valve-slide.
Fig. 5. is an outside plan.
The body of the valve consists essentially of three picces, viz. a centre casting or
distance piece A, and two side castings or flanges B and C. The faces of the
distance piece and the flanges are planed or faced to make sound joints. The
slide D, works against the planed faces of B and C, and within the distance piece A.
It is faced so as to work easily up and down in contact with and between the
parallel faces of B and C.
The slide is actuated by the screwed spindle E, which has a right and left
handed thread, the former working through the flanged nut F at the top of the
distance piece A and the latter entering the body of the slide D, into which it is
screwed. When the position of the slide is determined the lock-nut G is screwed
tight down to prevent any possible leakage.
The valve is prepared for bolting to the flanges of adjoining pipes &c. in such a
way as to make them perfectly solid with the valve which latter is clasped between
the flanges and bolted right through with single bolts instead of a separate set or
ring of bolts on either side of the valve.
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. The valve is so constructed that the width or distance from outside to outside,
measured along its axis, does not exceed one third of the similar dimension in any
other valve used for similar purposes or for gas, and having the same bore or
diameter of open-way.
2. Making the flanges a part of the solid body of the valve, instead of casting
them on necks or collars projecting from both sides of the valve as is the case in
all valves hitherto used for similar purposes.
3. The provision for attaching or bolting the valve to adjoining flanged pipes,
connections or the like, by single bolts passing right through the entire width of
the body of the valve so as to clasp or clamp the adjoining flanges to which the
valve may be connected and the parts forming the body of the valve tightly
together into one block, instead of a separate series of bolts on either side.
Dated this Fifth day of February 1894.
