Improvements in and relating to Valves, especially designed for
Drawing Off or Controlling the Passage of Sewage or its
Effluent or Gases.
We SAMUEL HENRY ADAMS Hydraulic Engineer Peaseholm Green York
and MOSES JAMES ADAMS Sanitary Engineer Peaseholm Green York, 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 improvements consist amongst other things in the application of a wedge
movement similar to that of a screw down penstock to a closed-in valve in order
that where desirable and especially in connection with sewage tanks a cheap
reliable valve may be used-rather than the costly valves now employed-and also
in the way we secure the swivel movement of the floating outlet arm as a part of
the valve first named.
Reference to our drawings will make our invention clear. At A Fig. 1 is a
length of cast iron pipe (in this instance built into a wall) having two flanges
thereon. The flange B is provided with holes through which bolts C. C are
placed, these bolts coupling to the flange B another flanged casting E which is so
constructed that when the two are in position a space is left between-this space
being provided in order that another flanged casting F may be held therein-and
at the same time that the casting F and its main bend G. attached thereto with
pipe H. shall be free to swivel up or down as the float J rises or falls in the liquid
around, or as the pipe H may be otherwise raised or lowered. We prefer to form
a cavity or recess K. in our flange faces, and in these we prefer to place brass or
other suitable metal rings or washers, allowing these to be held only in place by
contact with the various parts and we secure thus easy moving wearing surfaces.
The float J is attached to pipe H. by bolts M and stays N. We prefer to arrange
the attachment at M in such a manner that the relative angles the float and pipe H
shall bear to each other may be adjusted as desired. At Fig. 2 we shew our
wedge movement valve where A is the body of the valve B the valve door or
sliding face. C the faces upon which it closes. D the screw spindle working in
nut E by which the valve is raised or lowered and F a slot which may be provided
at both sides of the valve body in order that the valve face sliding up and down
within this body shall be loosely held in the desired position. At G we shew one
of the wedges attached to the valve body-and at H dotted will be seen one of the
wedges attached to the valve door itself, and it will be evident that when the
crew E is turned and the valve door moved downwards (this may be contrived in
any desired manner) these two wedges coming in contact the valve door will be
forced against the valve body faces C. and the passage of any passing body, liquid
or otherwise will be stopped. We prefer to form the face of our valve of a less
diameter than that of the orifice at the opposite end, to enable us thus to insert a
cool here which shall machine the desired face. At Fig. 3 we shew such a valve
loor-where the wedges are marked H-the screw spindle in this case may work in a
ug J the spindle thus being held stationary in a stuffing box. At Fig. 4 we shew
plain light door with wedges H and an attachment for simply raising by hand-
n such a case the screw spindle is not required. It is evident that the movement
f the valve may be caused in many ways but what we desire is simply to arrange
o place within a valve body a valve door or faces or a face which shall by coming

page_text: into contact with a wedge or wedges, attached to a valve body regulate or shut off
entirely the passage of any body, liquid gaseous, or semi liquid through it--and in
another form at Fig. 5 we shew wedges very similarly contrived. These wedges
operate within a valve body in the following manner-A spindle working freely
on a wedge having two faces is raised by hand or by screw movement up or down,
taking with it the wedge-and the two faces which are loosely attached thereto.
Now when the central wedge is down it comes into contact with the wedges of the
valve faces, forcing these faces against the faces of the main body of valve-the
act of withdrawing the central wedge will remove the pressure before exerted on
the valve faces, making the act of opening the valve entirely an easy one.
manner in which we attach our valve faces to our spindle is immaterial-here we
shew them coupled thereto by a simple link through which the spindle passes. In
our drawings at Fig. 5-A is the main body of valve B. its faces. CC. the valve
door or faces D the wedges attached thereto E the main central wedge F the
links attaching the valve faces to spindle--with G the spindle and H as desired a
screw nut or stuffing box.
The
And now having particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st. In a valve the use of a wedge or wedges attached to a valve face in com-
bination with a wedge or wedges attached to a valve body all so placed and
working within the said body in such a manner that the contact of these wedges
shall shut off or control the passage of liquids gases or semi liquid as shewn by my
drawings.
•
2nd. In a sluice valve the use of wedges within a closed body for the purpose of
forcing such valve faces together arranged as shewn.
3rd. In a sluice valve the placing of the face as C which requires tooling-in
such a position opposite to G. and the making this face C of a less dimension
-across-its-diameter-than-G.-in-order-that-it-may be freely tooled by the introduction
of a straight tool-at G. as shewn at Fig. 2.
4th. In a valve for withdrawing effluent or other purposes the swivel movement
as obtained by an attachment of flanges and faces as shewn at Fig. 1.
5th. The use for above of a valve so contrived that the swivel movement desired
is given and at the same time that the pipe or other connection as G. H. is held in
place only by the faces and flanges giving such movement.
6th. The use of the groove or grooves cut in a flange or flanges in combination
with a collar or washers or ring which shall be placed in said groove or grooves
for the purposes of our invention.
7th. The use of a wedge which moving down shall force asunder valve faces, to
close a valve or which being raised shall withdraw these faces from contact with a
valve body, the said faces being then freely raised all for the purposes of our
invention in combination with a valve body.
8th. All the several parts as shewn and described and their equivalents though
differing in form yet practically the same and for the same purpose.
