IMPROVED MECHANICAL ARRANGEMENTS APPLICABLE TO PUMP BUCKETS AND PARTIY
Year: 1868

page_text: LETTERS PATENT to Francis Reddicliffe, late of Seglenlas Mine,
Llanidloes, in the County of Montgomery, now of Hendre Mine,
in the County of Flint, Mine Agent, for the Invention of "IMPROVED
MECHANICAL ARRANGEMENTS APPLICABLE TO PUMP BUCKETS AND PARTIALLY
Sealed the 1st December 1868, and dated the 5th June 1868.
PROVISIONAL SPECIFICATION left by the said Francis Reddicliffe
at the Office of the Commissioners of Patents, with his Petition,
on the 5th June 1868.
I; FRANCIS REDDICLIFFE, late of Seglenlas Mine, Llanidloes, in the
County of Montgomery, now of Hendre Mine, in the County of Flint,
Mine Agent, do hereby declare the nature of the said Invention for
"IMPROVED MECHANICAL ARRANGEMENTS APPLICABLE TO PUMP BUCKETS AND
PARTIALLY APPLICABLE TO PISTONS," to be as follows:-
My former Patent, dated 21st June 1867, No. 1821, comprised certain
improvements in pump buckets and pistons whereby, as described in the
Specification thereof, their packing could from time to time be effectually
adjusted as the same became worn away.

page_text: By my present Invention in lieu of the arrangements described in the
said Specification, with the exception of the fork and the bar at the
bottom of the pump, which may be the same as in my former Patent, I
use the following arrangements: -I construct the bucket in divisions,
one division being recessed to receive the packing or gearing, and
another division being of -sufficiently large diameter to allow the first-
mentioned division to fit therein, the packing or gearing being fitted in
the recessed portion aforesaid; across the recessed division a bar is secured
through which a screw or adjuster attached to the fork above mentioned
or otherwise works, and by operating on which by means of a bar at
the bottom of the pump, in similar manner to that described in the
Specification of my former Patent or by other means, one of the
divisions is caused to move within the other and the packing or
gearing is thereby pressed out and adjusted. I sometimes prefer the
screw and fork to be dispensed with and the outer ring to be made to
screw upon the inner one. The bar at the bottom of the pump should
be adjustable by means of rack and pinion or other suitable mechanism,
and a bar should be used across the unrecessed division to carry the
fork and screw.
Pistons of engines are arranged in similar manner to the buckets
as aforesaid. The valves of the said buckets I prefer to construct as
follows: In the centre or other part of the ordinary valve I have a
smaller valve of similar construction whereby more than one opening
for the exit of fluid is provided upon the opening of the valves.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Francis Reddicliffe in the Great Seal Patent
Office on the 5th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
REDDICLIFFE, late of Seglenlas Mine, Lanidloes, in the County of
Montgomery, now of Hendre Mine, in the County of Flint, Mine 3
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of June, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give 3

page_text: and grant unto me, the said Francis Reddicliffe, Her special licence
that I, the said Francis Reddicliffe, my executors, administrators, and
assigns, and such others as I, the said Francis Reddicliffe, my 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, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVED MECHANICAL
ARRANGEMENTS APPLICABLE TO PUMP BUCKETS AND PARTIALLY APPLICABLE TO
PISTONS," upon the condition (amongst others) that I, the said Francis
Reddicliffe, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 Letters Patent.
NOW KNOW YE, that I, the said Francis Reddicliffe, 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:-
My former Patent, dated 21st June 1867, No. 1821, comprised certain
improvements in pump buckets and pistons whereby, as described in the
Specification thereof, their packing could from time to time be effectually
adjusted as the same became worn away.
In lieu of the arrangements described in the said Specification, with
the exception of the fork and the bar at the bottom of the pump, which
may be the same as described in that Specification, I use the following
arrangements:-1 construct the bucket in divisions, one division being
recessed to receive the packing or gearing, and another division being
of sufficiently large diameter to allow the first-mentioned division to fit
therein, the packing or gearing being fitted in the recessed portion
aforesaid. Across the recessed division a bar is secured, through which
a screw or adjuster attached to the fork above mentioned (or otherwise)
works, and by operating on which by means of a bar at the bottom of
the pump, in similar manner to that described in the Specification of my
former Patent, or by other means, one of the divisions is caused to move
within the other, and the packing or gearing is thereby pressed out and
adjusted. The bar at the bottom of the pump should be adjustable by

page_text: means of rack and pinion or other suitable mechanism and a bar should
be used across the unrecessed division to carry the fork and screw. I
sometimes prefer the screw and fork to be dispensed with and the outer
ring or division to be made to screw upon the inner one.
Pistons of engines are arranged in similar manner to the buckets as
above mentioned. The valves of the said buckets I prefer to construct
as follows: In the centre or other part of the ordinary valve I
have a smaller valve of similar construction, whereby more than
one opening for the exit of fluid is provided upon the opening of the
volvos

Having now particularly described and ascertained the nature of the
said Invention, and in what manner the same is to be performed and
carried out in practice, I hereby declare that I claim the Invention of
Improved Mechanical Arrangements applicable to Pump Buckets and
partially applicable to Pistons," the nature and character whereof is set
forth by the words precceding the works Description of the Drawings,
it being understood that I do not claim the mere constituent details per
se and apart from the purposes of my said Invention.
In witness whereof, I, the said Francis Reddicliffe, have hereunto
set my hand and seal, this 3rd day of December, in the year of
our Lord One thousand eight hundred and sixty-eight.
