page_text: I, FRED ASHTON of Vickerman Street, Halifax, in the County of York, Plumber
do hereby declare the nature of this invention to be as follows:-
This invention relates to improved construction of appliances for purpose
aforesaid, and is designed to secure an increased area, or water way passage.
According to this my said invention I bush the upper part or cap of the box with
a ring of brass through which is bored or formed a hole of diameter or capacity
equal to the interior of the stand pipe
The upper part of the bush is countersunk-that is to say-the angle or aris
around the hole is turned off or cut away Upon the face of the said bush which
is level with the face of the cap I employ a packing washer of india rubber or other
like material having a corresponding hole and also countersunk or angled on the
face.
On the opposite surface of the packing washer is a projecting rim extending
around the hole and angled or feathered to an edge, which rim lies in the counter-
sunk part of the bush above mentioned and which serves to keep the packing washer
in true position over the disc, the countersunk part of the packing ring forms the
seating for the ball, there is thus a perfectly clear and open way for the water, there
being no overhanging edges or parts of the packing and seating washes as
heretofore employed, which overhanging parts impeded the flow, but were indis-
pensable in order to protect the ball from contact with the bore metal of
the cap.
The lower part of the box I construct balloon shaped and employ spaced vertical
ribs which afford ample room for passage of the water between them whilst the ribs
serve to keep the ball in true position within the ball box.

page_text: I, FRED ASHTON of Vickerman Street, Halifax in the County of York, Plumber,
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:
This invention relates to improved construction of appliances for purpose aforesaid,
and is designed to secure an increased area or water way passage.
According to this my said invention I bush the upper part or cap of the box with
a ring of brass through which is bored or formed a hole of diameter or capacity
equal to the interior of the stand pipe. The upper part of the bush is countersunk
that is to say, the angle or aris around the hole is turned off or rounded away.
Upon the face of the said bush which is level with the face of the cap 1 employ a
packing washer of india rubber or other like material.
On one side of the said packing washer is a projecting circular rim extending around
the hole and which rim lies in the countersunk part of the bush above mentioned
and which serves to keep the packing washer in true position over the disc, the
circular rim part of the packing ring forms the seating for the ball, there is thus
a perfectly clear and open way for the water, there being no overhanging edges or
parts of the packing and seating washers as heretofore employed, which overhanging
parts impeded the flow, but were indispensable in order to protect the ball from
contact with the bore metal of the cap
The lower part of the box I construct balloon shaped and employ spaced vertical
ribs which afford ample room for passage of the water between them whilst the
ribs serve to keep the ball in true position within the ball box.
Such being the nature and object of this my said invention, the following is a
complete description of same reference being had to the accompanying drawings:
Fig 1 is a sectional elevation of the improved valve and ball box.
Fig. 2 is a sectional plan on line A. B of fig. 1, the ball being shewn in
elevation.
The several figs. on sheet 2 are details of the valve and ball box detached.
At 1 is the box of the valve to which by bolts 2-3 is secured the plate 4 under
the rabit or recess 5 is the flange of the ring of brass 6 which is of concave form as
shewn, corresponding to the exterior of the india rubber ring 7 which forms a
watertight joint for the plates 5-6 and also a seating for the ball 8 the orifice or
discharge way being through the opening forming interior of the ring 7, the
projecting ribs 9 in the box 1 serve to keep the ball 8 in a central position in the
box when it is forced down, and the valve is open, also ensuring ample passage
ways at 10-10 for the water, past the ball 8 and to the outlet, 11 is a loose cap for
covering the valve seat 7 and ball 8.
It will be obvious that the flange of the ring 6 may be extended so as to receive
the bolts 2-3 and thereby dispense with the plate 4 but 1 prefer the use of the
ring 6 as shewn, because its first cost is less and cost of replacement when worn
Is less.

page_text: Having now particularly described and ascertained the nature of this my Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. Improvements in ball boxes wherein is combined a box having the ribs 9,
ball, washer 7, ring 6 and plate 4 all in combination as and for the purpose
herein fully described and illustrated by annexed drawings.
2. I claim the flanged ring 6 and indiarubber washer 7 in combination with ball 8
constructed and applied as and for purpose herein fully described and illustrated
by annexed drawings.
Dated this 5th day of March 1889.
