PROVISIONAL SPECIFICATION.
An Improved Sluice or Device for Controlling the Flow of Liquids.
I, FREDERICK SPENCER METCALFE, of The Sewage Pumping Station, Stretton,
in the County of Stafford, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
The object of my invention is to provide a simple and cleanly sluice or device
for controlling the flow of liquids, my invention being chiefly designed for con-
trolling the flow of sewage in and about sewage works but as will be readily under-
stood it may be also used for other liquids or semi-liquids.
My invention consists of an outer casing in two parts, each of which is bored
or otherwise formed with a waterway of preferably but not necessarily the same
diameter as the interior of the pipes to which they are bolted or fixed in any well
known manner. One side of the casing has a flang cast or formed thereon all
round, thus a space is left between the two sides, in which a slide is free to move
backwards and forwards when operated from the outside. This slide is formed
with an orifice of the same size as the openings in the two sides of the casing so
that a full way is obtained when the three orifices are concentric, it also has a
blank portion thereon so that the flow of the liquid may be cut off and under
absolute control from the outside by simply pushing the slide backwards and
forwards with a rod or other device passing through the casing.
When the slide and ways have been thoroughly lubricated and the whole
bolted together, the flow of liquid may be regulated as required without fear of
any objectionable matter passing into the parts of the sluice between the slide
and casing.
Any suitable stops or locks may be provided for stopping the slide in its desired
positions and in the case of large sluices inspection boxes or openings may be
formed at or near the ends of the casings for lubricating and cleansing purposes
without stopping the flow of liquid: any suitable means may be employed for
operating the slide rod.
Although a flange is herein mentioned as being case or formed on one side
and between the two parts of the casing it will be evident that a separate piece
would answer the same purpose as the bolts would hold it securely in position.

page_text: 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 object of my invention is to provide a simple and cleanly sluice or device
for controlling the flow of liquids, my invention being chiefly designed for con-
trolling the flow of sewage in and about sewage works but as will be readily under-
stood it may be also used for other liquids or semi-liquids.
In describing my invention reference will be had to the accompanying sheet
of drawings upon which Figure 1 is a sectional elevation on line aa of Figure 2.
Figure 2 is a section on line b-b of Figure 1.
My invention consists of an outer casing in two parts A and B each of which is
bored at C or otherwise formed with a waterway of preferably but not necessarily
the same diameter as the interior of the pipes to which they are bolted or fixed
in any well known manner such as by bolting them to the flanges' C; C2. One
side of the casing A has a flange A¹ cast or formed thereon all round, thus a space D
is left between the two sides, in which a slide E is free to move backwards and
forwards when operated from the outside. This slide is formed with an orifice E'
of the same size as the openings in the two sides of the casing so that a full way
is obtained when the three orifices are concentric, it also has a blank portion E²
thereon so that the flow of liquid may be cut off and under absolute control
from the outside by simply pushing the slide backwards and forwards with a
rod F or other device passing through the casing, the rod F may pass through, a
stuffing box G and be operated from its outer extremity by means of a screw,
balance weight or any other suitable device, the latter not constituting any part
of the invention is not shewn upon the drawings.
When the slide and ways have been thoroughly lubricated and the whole bolted
together, the flow of liquid may be regulated as required without fear of any
objectionable matter passing into the parts of the sluice, between the slide and
casing, it will be observed that as the slide is operated backwards and forwards
any matter that may accumulate between it and the casing, when. the former is
closed, is simply pushed back into the full aperture when it is opened.
Any suitable stops or locks may be provided for stopping the slide in its desired
positions and in the case of large sluices inspection boxes or openings H may be
formed at or near the ends of the casings for lubricating and cleaning purposes
without stopping the flow of liquid.
Although a flange is herein mentioned as being cast or formed on one side
and between the two parts of the casing it will be evident that a separate piece
would answer the same purpose as the bolts I would hold it securely in position.
The meeting faces of the slides and the other internal parts of the device may be
faced with any metal or material best suited for its purpose.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:.
The improved device or sluice for controlling the flow of sewage and other liquids
or semi-liquids, consisting of the casing A, B with waterway C, flange or distance
piece A', with or without the cleaning doors H; in combination with the slide E
having orifice E and blank portion E³, operated by the rod F, substantially as
described and illustrated...
