PROVISIONAL SPECIFICATION.
Improvements in or relating to Bucket Pumps.
I, JAMES MCEWEN of 11 Rushton Street, Hulme, Manchester in the County
of Lancaster, Engineer, do hereby declare the nature of my said invention to be as
follows:-
This invention refers to improvements in or relating to bucket pumps, such as,
soda water pumps, syrup pumps, and others for pumping water and other liquids,
and consists in means which allow of the bucket leather or packing being tightened
or slackened without taking the same out of the pump barrel. This invention also
admits of a single bucket leather or packing being employed in place of two as in
pump buckets at present in use, thereby reducing friction to a minimum. This I
accomplish by mounting the bucket leather or packing on the body of the bucket,
and secure the same in position by means of a screwed ferrule or its equivalent.
Between the bucket leather or packing and the ferrule or its equivalent is placed
an india-rubber or other elastic ring held in position by a metallic ring or plate and
a disc; the latter being secured in the body of the bucket in any convenient manner
so as to allow of the india-rubber or other elastic ring being operated upon to press
or force the bucket leather or packing against the working surface of the pump.
The disc is provided with means to allow of the same being turned by a screw-key
or any other tool suitable for the purpose to operate on the india-rubber or other
elastic ring according to the pressure required to make the bucket leather or
packing tight on its working surface. If desired the disc can be locked in position
by any suitable mechanical means. The pump barrel is provided with an opening
in any convenient place to allow of the disc being operated without removing the
bucket therefrom; the said opening being closed by a plug or other cover.

COMPLETE SPECIFICATION.
Improvements in or relating to Bucket Pumps.
I, JAMES MCEWEN late of 11 Rushton Street, Hulme, Manchester in the
County of Lancaster, and now of Ruthven House, Bowden Lane, Marple in the
County of Cheshire, Engineer, do hereby declare the nature of my said 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 refers to improvements in or relating to bucket pumps, such as,
soda water pumps, syrup pumps, and others for pumping water and other liquids,
and consists in means which allow of the bucket leather or packing being tightened
or slackened without taking the same out of the pump barrel. This invention also
admits of a single bucket leather or packing being employed in place of two as in
pump buckets at present in use, thereby reducing friction to a minimum. This I
accomplish by mounting the bucket leather or packing on the body of the bucket,
and secure the same in position by means of a screwed ferrule or its equivalent.
Between the bucket leather or packing and the ferrule or its equivalent is placed
an india-rubber or other elastic ring held in position by a metallic ring or plate
and a disc; the latter being secured in the body of the bucket in any convenient
manner so as to allow of the india-rubber or other elastic ring being operated upon
to press or force the bucket leather or packing against the working surface of the
pump. The disc is provided with means to allow of the same being turned by a
screw-key or any other tool suitable for the purpose to operate on the india-rubber

or packing tight on its working surface. If desired the disc can be locked in
position by any suitable mechanical means. The pump barrel is provided with an
opening in any convenient place to allow of the disc being operated without removing,
the bucket therefrom; the said opening being closed by a pling or other cover.
Fig. 1 is a sectional elevation of my improved pump bucket.
Fig. 2-is-a plan of top side of same.
Fig. 3 is a sectional plan through line A B in Fig 1, and
Fig. 4 is a part sectional elevation of my improved bucket as applied to syrup
pump of my patent rapid paragon filling machine, the latter being provided with
means to allow of the bucket leather or packing ring being tightened or slackened
without removing the bucket from the pump barrel.
C is the pump barrel; D the pump or bucket rod, and E the body of the bucket.
The bucket leather or packing G is mounted on the body E, and is secured thereon
by means of the screwed ferrule H. The latter is provided with the slots or
recesses I to allow of its being screwed up or otherwise by means of a forked 'tool.
Between the bucket leather or packing G and the ferrule H is placed the india-
rubber or other elastic ring J held in position by the metallic ring or plate K'and
the disc L. The disc L is screwed into the body E of the bucket, by which 'the
india-rubber or other elastic ring J can be operated upon to press or force the
bucket leather or packing G against the working surface of the pump barrel C
to make a tight joint. The screwed disc L admits of any amount of pressure being
imparted to the india-rubber or other elastic ring J requisite to form a tight joint
between the bucket leather or packing G and the pump barrel C. The disc Lis
.provided with the square or other opening M or other equivalent means to admit
of the same being operated in either direction by a square ended or other key.
After the disc L has been screwed down sufficiently to make a tight joint between
the bucket leather or packing G and the pump barrel C it is locked in position by
the set screw N passing through the bottom end of same into the end of pump or
bucket rod D. The head of the set screw N is provided with a saw-cut to allow
of the same being operated by a screw driver.
An important part of this invention is that the bucket leather or packing G
can be tightened or slackened without removing the same from the pump barrel C.
This I effect by providing the end of the latter with the opening P sufficiently
large to admit a square ended or other key to fit into the opening M, and close
the said opening by the screwed plug or other cover O as shown in Fig. 4.
case of small pumps the body E of the bucket can be formed on the end of the
pump or bucket rod D, thereby dispensing with the screw P' or its equivalent.
In
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 1
claim is :-
1. The general arrangement, construction, and combination of parts composing
the improved pump bucket with a single bucket leather or packing ring that
can be tightened or slackened by means of a screw key or other means without
removing the same from the pump barrel as hereinbefore described and as illus-
trated in the annexed drawings.
2. As means for tightening or slackening the bucket leather or packing ring of a
pump bucket without removing the latter from the pump barrel, the disc L with
the opening M or its equivalent, with or without the locking arrangement, sub-
stantially in the manner described and as illustrated in the drawings.
**
3. In combination with the pump barrel C the use of the opening 'P an. rewed
plug or other cover O, substantially as described and for the purpose spec.
