the Invention of "IMPROVEMENTS IN PUMP BUCKETS, WHICH IMPROVEMENTS

PROVISIONAL SPECIFICATION. left by the said Myles Kennedy and
Thomas Eastwood at the Office of the Commissioners of Patents, with
their Petition, on the 22nd December 1855.
We, MYLES KENNEDY, of Ulverstone, in the County of Lancaster, and
THOMAS EASTWOOD, of Preston, in the same County, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN PUMP BUCKETS, WHICH IM-
PROVEMENTS ARE ALSO APPLICABLE TO LIFT PUMP'S, AIR PUMPS, AND ALL SIMILAR
APPARATUS," to be as follows:-
Our Invention consists of using an expanding metal ring clack of such con-
struction that as the bucket rises against the said ring clack it causes the same
to expand from its peculiar form and construction, as will be clearly under-
stood by reference to the accompanying outline Drawing, in which the working
barrel and pump bucket are shewn in section. A represents the top and
bottom guard; B, the expanding metal ring clack; C, the bucket seating;
and D, the working barrel.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Myles Kennedy and Thomas Eastwood in the Great Seal
Patent Office on the 20th June 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MYLES
KENNEDY, of Ulverstone, in the County of Lancaster, and THOMAS EASTWOOD,
of Preston, in the same County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Twenty-second day of December, in the
year of our Lord One thousand eight hundred and fifty-five, in the nineteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Myles Kennedy and Thomas Eastwood, Her special
licence that we, the said Myles Kennedy and Thomas Eastwood, our executors,
administrators, and assigns, or such others as we, the said Myles Kennedy and
Thomas Eastwood, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN PUMP BUCKETS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO LIFT
PUMPS, AIR PUMPS, AND ALL SIMILAR APPARATUS," upon the condition (amongst
others) that we, the said Myles Kennedy and Thomas Eastwood, by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Royal Letters Patent.
NOW KNOW YE, that we, the said Myles Kennedy and Thomas East-
wood, do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say) :-
:-
.
Our said improvements. consist in employing an expanding ring clack,
which by its friction against the bore of the barrel is raised or lifted from its
seating when applied to a lift pump as the spears and bucket descend, thereby
allowing liquid to pass through to the barrel of the pump, and also causes it to
press against its seating (to which it is well fitted) when the spears and bucket
rise, thus preventing the escape of liquid downwards, and allowing it to be
lifted towards its ordinary exit at the upper part of the barrel. The ring clack

page_text: consists either of one or more expanding rings in conjunction with one that
does not expand, or of one expanding ring only. If more than one are used,
the ring which fits the seating may be, well fitted to the barrel, but not divided
or cut.
These improvements will be clearly understood, by reference to the accom-
panying Sheet of Drawings, with the figures and letters of reference thereon,
which are the same for similar parts in the different views.
Fig. 1 represents a section of part of a working barrel of a pump, with the
improved bucket; Fig. 2 is a plan of one of the guards; Fig. 3 is a plan of
the seating; Figs. 4 and 5 represent the expanding ring clack composed
of two parts; and Fig. 6, the expanding ring clack in one part.
The top and
bottom guards are represented at a, b; the expanding ring clack, which consists
of two parts of metal or other material, at c and c'; and the bucket seating
at d, between which and the bore of the working barrel e, a sufficient space
is left for the passage of the liquid, the upper part of the said seating being
conical, or of any desired shape, and is made true, so that when the part c¹ of
the ring clack is pressed upon it, no liquid shall escape. As before mentioned,
the ring c¹ is not cut, and therefore does not expand, but the ring c is cut, and
by expanding, fits the bore of the barrel, the notch or space being covered with
a facing when desired. Between the seating d and upper guard a there is
a greater distance than the depth of the rings c and c', so that a space f may
be obtained between the clack and its seating for the passage of the liquid
as the bucket descends. The guards and seating are placed upon the lower
part of the rod or spears 9, and are kept firm by the nuts h, which are
prevented from turning by the pin i in the usual manner. The expanding
ring clack is placed between the seating and upper guard, as shewn in.
Fig. 1, and the course of the liquid as it enters the barrel is represented by
arrows. The parts thus combined forming a bucket of great economy and
efficiency. It is evident these improvements may be applied to any kinds of
pumps.
Having thus fully described the nature of our said Invention, and in what
manner the same is to be carried into practical effect, we desire it to be under-
stood that we do not confine ourselves to the precise details herein set forth, as
such may be varied or modified without departing from the principle thereof.
But we claim as of our Invention, and which to the best of our knowledge and
belief has not been hitherto used within this realm,
Firstly, the expanding ring clank, which rises and falls by its friction
against the working barrel of a pump as the bucket moves up and down.

page_text: And, secondly, the general arrangement of apparatus,, as herein described,
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, we, the said Myles Kennedy and Thomas East-
wood, have hereunto set our hands and seals, this Eighteenth day
of June, One thousand eight hundred and fifty-six.
Witness,
ROBERT KENDALL,
Ulverstone.
