IMPROVEMENTS IN PUMPS POR SHIPS
Year: 1866

page_text: LETTERS PATENT to Thomas. Burton Taylor, of Seaham, in the County of
Durham, Shipowner, for the Invention of "IMPROVEMENTS IN PUMPS POR
SHIPS."
Sealed the 22nd March 1866, and dated the 25th September 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Burton Taylor
at the Office of the Commissioners of Patents, with his Petition, on
the 25th September 1866.
I, THOMAS BURTON TAYLOR, of Seaham, in the County of Durham, Ship-
owner, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN PUMPS FOR SHIPS," to be as follows:-
I furnish the pump barrel with what may be termed a solid plunger in the
sense of its occupation of space in the pump barrel; it is however hollow and
open at the top, permitting the connecting rod from the lever handle or crank
to pass to the lower part of such planger, where it is jointed thereto. The
plunger is fitted in a packed gland, or is otherwise sufficiently tight to obtain
the necessary vacuum in the barrel and to guide the plunger in its rectilinear
motion. I dispose one valve on the top of the suction pipe, the seat being
raised a little above the bottom of the pump chamber; this valve is of the
full area and passage of the suction pipe. The valve I prefer at this point is

page_text: a lift valve with a guiding stem above it, which works in a guide in a bridge
piece, or it might be a perforated diaphragm separating the valve chamber
from the body of the pump barrel. The delivery valve I place in the spout,
and use a pendant clack valve at that point. Thus I dispense with pump
boxes, and the pump will raise any floating or even denser matters that may
come up the pipe without danger of choking, having a free passage through-
out equal to the area of the suction pipe. It at the same time works very
easily and does not require the introduction of water at the top to obtain the
necessary vacuum in the first instance.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filod
by the said Thomas Burton Taylor in the Great Seal Patent Office on
the 23rd March 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BURTON TAYLOR, of Seaham, in the County of Durham, Shipowner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of September, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Burton Taylor, Her special licence that I, the said Thomas
Burton Taylor, my executors, administrators, and assigns, or such others as 1,
the said Thomas Burton Taylor, 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 "Im-
PROVEMENTS IN PUMPS FOR SHIPS," upon the condition (amongst others)
that I, the said Thomas Burton Taylor, 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 Thomas Burton Taylor, do hereby
declare the nature of my said Invention, and in what manner the same i is
to be performed, to be particularly described and ascertained in and by the

page_text: following statement, reference being had to the Sheet of Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to say) :-
I furnish the pump barrel with what may be termed a solid plunger in the
sense of its occupation of space in the pump barrel; it is however hollow and
open at top, permitting the connecting rod from the lever handle or crank to
pass to the lower part of such plunger, where it is jointed thereto. The
plunger is fitted in a packed gland, or is otherwise sufficiently tight to obtain
the necessary vacuum in the barrel and to guide the plunger in its rectilinear
motion. I dispose one valve on the top of the suction pipe, the seat being
raised a little above the bottom of the pump chamber; this valve is of the
full area and passage of the suction pipe. The valve I prefer at this point is
a lift valve with a guiding stem above, which works in a guide in a bridge
piece, or it might be a perforated diaphragm separating the valve chamber
from the body of the pump barrel. For simplicity and economy a clack
valve may be used if desired. The delivery valve I place on the spout, and
use a clack valve at that point in a somewhat pendant position. Thus I
dispense with pump boxes, and the pump will raise any floating or even denser.
matters that may come up the pipe without danger of choking, having a free
passage throughout equal to the area of the suction pipe; it at same time
works very easily, and does not require the introduction of water at the top to
obtain the necessary vacuum in the first instance.
DESCRIPTION OF DRAWINGS.
Figure 1 is a central vertical section of a ship's pump constructed according
to my Invention.
A, A, is the pump barrel bolted down on the deck in the usual manner;
this barrel A is provided with a stuffing box, packing, and gland b at the
upper part, and is furnished and fitted with a plunger C. The plunger must
be truly cylindrical and smoothly surfaced in order to work freely in the
packing; it should fit easily in the pump barrel A and gland b, which must
both be truly bored, the former however need not be the case throughout, but
only to a limited extent below the stuffing box, beyond which it should enlarge.
To the plunger C I connect a rod D by a joint d at the bottom of the
plunger, which is hollow as seen; the other end of rod D is attached to the
crank e of the shaft E, disposed transversely over the pump barrel, and carried
by two brackets (one on each side) fixed on the upper flange of the barrel A,
which extends at the sides for that purpose. The shaft E is furnished with a
fly wheel F and winch handles for operating the pump; f is the suction valve;
which in this case is an ordinary conical valve fitted to a seating and guided

page_text: by a stem 9 working in a guide arm h; i is the delivery valve, which is
simply a clack valve of leather with a metal backing fixed on the mouth of
the spout, as shown; thus it will be seen the passage for the water through-
out is uninterrupted and equal to the size of the suction pipe G, which should
be carried down to the bottom of the ship of same diameter. By operating
the crank axis the plunger C is caused to reciprocate, the upward stroke pro-
ducing the necessary void or vacuum in the pump barrel (the valve i being.
closed at the time) to suck the water up the suction pipe G, as well understood,
while the down stroke produces the delivery at the spout. Instead of operating
the plunger C by a crank it may be worked up and down by means of a lever
like an ordinary pump handle.
Figure 2 represents a partial external view and partial section of a pump
similar to that represented at Figure 1, but in which a clack valve is sub-
stituted for the lift valve before referred to and shown.
Figure 3 represents a lateral vertical section of a double pump constructed
according to my Invention, which is simply combining two pump barrels A, A,
and the constituent parts of the pump in duplicate, the plungers being
operated from a double crank shaft as seen. The two barrels A, A, both
open at bottom into same chamber and communicate with the same suction
pipe H. There may be two delivery spouts or only one, as shown in the
Drawings, in which case it opens and is common to both pump barrels, when.
so arranged one delivery valve i only is required.
Having described the nature of my Invention, and the manner of performing
the same,
I declare that what I claim as my Invention to be protected by the
berein-before in part recited Letters Patent is, the arrangement and combina-
tion of parts represented in the Drawings and operating as herein-before
described constituting pumps for ships' purposes.
In witness whereof, I, the said Thomas Burton Taylor, have hereunto
set my hand and seal, this Twenty-first day of March, in the year
of our Lord One thousand eight hundred and sixty-seven.
