Year: 1875

page_text: LETTERS PATENT to Jobu Musgrave Sagar-Musgrave, Joseph
Backhouse Akcroyd, and Daniel Ward, all of Leeds, in the County
of York, for the Invention of "IMPROVEMENTS IN PUMP BUCKETS, AND
VALVES FOR THE SAME."
PROVISIONAL SPECIFICATION left by the said John Musgrave
Sagar-Musgrave, Joseph Backhouse Akeroyd, and Daniel Ward at
the Office of the Commissioners of Patents, with their Petition,
on the 19th July 1875
WC, JOHN MUSGRAVE SAGAR-MUSGRAVE, JOSEPH BACKHOUSE
AKEROYD, and DANIEL Ward, all of Leeds, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PUMP BUCKETS, AND VALVES FOR THE SAME," to be as follows.-
This Invention relates to the buckets used in ordinary lift
pumps, and
is especially applicable to such pumps when used in collieries and
mines, but it may also be used in pumps applied to other purposes. It
has for its object novel methods of constructing and arranging the

page_text: buckets and valves for such pumps so that they shall be stronger,
cheaper, and more durable than buckets and valves of the kinds
ordinarily constructed and used.
We make the bucket of metal or other suitable material in the form
of a hollow tube of any convenient length, but preferably of as great 5
length as the pump will allow When of sufficient length it may be
made to fit the pump accurately and to work without packing, but it
may be provided with grooves or recesses round it with or without
packing or rings of metal or other suitable material.
We prefer to make the bridge across the upper end (to which the 1
pump rod is fastened) of one picce with the bucket, but sufficiently high
above the latter to allow of the introduction under it (when the pump
rod is removed) of valve of metal or ōther suitable material-which fits
upon a seat on the upper edge of the bucket. When the pump rod is
replaced in the bridge its lower end serves as a stop to retain the valve ]
in its place and prevent it from rising too high. The pump rod is
preferably fixed by one or more nuts screwed upon it below the bridge,
but leaving sufficient of its end projecting to act as a stop, as already
described.
In order that ample waterway may be allowed through the bucket,
we make no central stem or spindle to the valve, but we form three or
more equidistant rings or guides upon its lower side which fit against
the inner side of the bucket as they rise and fall. The lower edge of
the bucket is preferably brought to a thin edge so as to cause less
resistance and give the least possible friction, and the nuts upon the :
pump rod may be prevented from unscrewing by a split pin through the
latter.
By the method of construction described we make the pump bucket
and valve very strong, cheap, and durable, whilst great waterway is
afforded through the valve, and by making the bucket of much greater
length than the pump buckets as ordinarily constructed and used the
water is prevented from passing by it, and it secures at all times a full
Lift of water at each stroke; thus pumping "solid" and avoiding the
wear and tear caused if the water only partially fills it.

filed by the said John Musgrave Sagar-Musgrave, Joseph
Backhouse Akcroyd, and Daniel Ward in the Great Seal Patent
Office on the 19th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, John
MUSGRAVE SAGAR-MUSGRAVE, JOSEPH BACKHOUSE AKEROYD, and
DANIEL WARD, all of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Ier
Letters Patent, bearing date the Nineteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said John Musgrave Sagar-Musgrave, Joseph
Backhouse Akeroyd, and Daniel Waid, Her special licenco that we, the
said John Musgravo Sagar-Musgrave, Joseph Backhouse Akeroyd, and
Daniel Ward, our executors, administrators, and assigns, or such others
as wc, the said John Musgrave Sagar-Musgrave, Joseph Backhouse
Akcroyd, and Daniel Ward, our executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, usc, exercise, and vend, within the United King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN PUMP BUCKETS, AND VALVES FOR
THE SAME," upon the condition (amongst others) that we, the said John
Musgrave Sagar-Musgrave, Joseph Backhouse Akeroyd, and Daniel
Ward, our exccutors or administrators, by an instrument in writing
under our, or their, or one of their hands and scals, should particularly
describe and ascertain the nature of the said Invention, and in what
mannci 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 Letters Patent.
NOW KNOW YE, that we, the said John Musgrave Sagar-Musgrave,
Joseph Backhouse Akeroyd, and Daniel Ward, do hereby declare the
nature of our said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawing (that is to say) :-
Our Invention relates to the buckets used in ordinary lift pumps, and

page_text: it is more especially applicable to the buckets and valves of such pumps
when used in collieries or other mines, but it can also be applied to the
buckets and valves of pumps used for other purposes It has for its
object novel methods of constructing and arranging the buckets and
valves for such pumps so that they are stronger, cheaper, and more
durable than buckets and valves of the kinds ordinarily constructed and
used.
In order to carry out our Invention we make the bucket of metal or
other suitable material in the form of a hollow tube of as great a length
as the barrel of the pump in which it is to be used will allow. We
prefer to make it fit as accurately as possible into the barrel, and to use
it without leather, metal, or other packing rings; but such packing of
the kinds ordinarily used may be applied if desired, the bucket-being in
such case provided with suitable grooves or recesses round its cir-
cumference for the reception of such packing.
We prefer to make the bridge across the upper end of the bucket
(to which the lower end of the pump rod is attached) of one piece with
the bucket itself, but we make it sufficiently high above the latter to
allow of the introduction under it and into the bucket (when the pump
rod is removed) of a valve of any suitable material, but preferably of
brass or other metal which fits upon a scat formed upon the upper edge
of the bucket. After the valve has been inserted in its place, as
described, the pump rod is replaced in the bridge to which it is fixed,
and its lower end then serves as a stop to retain the valve in its place
and prevent it from rising too high. We fix the pump rod in the bridge,
preferably by one or more nuts screwed upon its end below the budge,
a sufficient length of the end being left projecting below the nut to act
as a stop for the valve, as already described.
In order that the waterway through the bucket and valve may be of
as large area as possible, we make no central guiding stem or spindle to
the valve, but we form three or more equidistant wings or guides upon
its lower side which are guided against the inside of the tubular bucket
as they rise and fall; and we prefer to bring the lower edge of the
bucket to as thin an edge as possible so as to cause less resistance and
give the least possible friction against the water when the bucket is
making its down stroke.

page_text: The nuts upon the pump rod, as described, should be prevented from
unscrewing by means of a split pin or cotter passed through the rod.
The accompanying Drawing is in illustration of our Invention.
Figure 1 is a side view of a bucket and valve; Figure 2 is a vertical
transverse section; and Figure 3 a plan from above of the same.
Figure 4 is a separate view of the valve; and Figure 5 is a plan of
the valve from below.
a is the tubular bucket which if necessary may have packing rings
round it, as shewn at b, c, d. The lower edge of the bucket at e is
brought to as thin an edge as possible The bridge fis formed of one piece
with the bucket, and is made sufficiently high to allow the valve g to
be introduced under it and dropped upon the seat / formed in the
bucket a; the pump rod i is then fitted into the bridge f, and is fixed
by the nut k and pin l, its lower end being long enough to form a stop
to the valve g, as shown in dotted lines in Figure 2 The valve g has
no central guide, but is shown (in Figures 4 and 5) with five wings or
guides round its lower side which fit into the cylindrical part of the
bucket a (as shewn in Figure 2). The lower ends of the guides upon
the valve are tapered down to as small a size as possible.
By the method of construction and arrangement described and shewn
in the Drawing we make the pump bucket and valve very strong,
cheap, and durable, whilst great waterway is afforded through them;
and by making the bucket, as described, of much greater length than
pump buckets, as ordinarily constructed and used, the water is prevented
from passing by its outside, and a full lift of water at each stroke is at
all times secured, the pump thus pumping "solid" and avoiding the
wear and tear caused if the water only partially fills it.
In witness whereof, I, the said Joseph Backhouse Akeroyd, have
hereunto set my hand and seal, this Seventeenth day of January,
in the year of our Lord One thousand eight hundred and seventy-
