Year: 1819

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TYROR, of Liverpool, in the County of Lancaster, Coachmaker, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great
Britain and 'Ireland, bearing date at 'Westminster, the Thirteenth day of
'March, in the fifty-ninth year of His reign, did give and grant unto me,
the "said: William Tyror, my executors, administrators, and assigns, His special
licence, full power, sole privilege and authority that I, the said Willam Tyror,
my executors, administrators, and assigns during the term of years therein
expressed, should and lawfully might make, use, exercise; and vend, within
England, Wales; and the Town of Berwick-upon-Tweed; my 'Invention of
1 CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF PUMPS, AND IN THE MACHINERY
FOR WORKING THE SAME;" in which Letters Patent there is contained a proviso
obliging me, the said William Tyror, under my hand and seal; 'to causé à
particular description of the nature of my said Invention, and in what
manner the same is to be performed; to be inrolled in His Majesty's' High
Court of Chancery within two calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same
(relation being thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Tyror, do hereby declare that my said Invention is fully described and
ascertained by the 'Drawings in the margin of these Presents, and by the
following description thereof (that is to say)

page_text: My Invention of Certain Improvements in the Construction of Pumps, and
in the Machinery for Working the Same, consists in four brass chambers
marked P, P, P, P, in the Drawing No. 5, joined together by means of breech
pieces with screws, and soldered across the joints, these breech pieces, marked
Q, Q, in the Drawing No. 5, being cast of brass or any other suitable metal.
When these are complete together, and that marked P, p, in the Drawing
No. 5, being placed upon the breech piece marked Q, q, in the Drawing
No. 5, I fix them to or under a box or frame suitable for the purpose. I then
furnish this box or frame with eight brass grooves, as marked 0, 0, 0, 0, in
the Drawing No. 4, fastened to the sides with screws.. I then furnish it with
a crank, or four cranks in one, that is, one crank out of each side of the same
piece; of square iron or any suitable metal, being one up, one down, one
towards you, and one from you.
My further improvements are in the formation of one end of the crank or
cranks. I fix two tooth and pinion wheels at a sufficient distance from each
other upon the end of the crank above mentioned to allow two wheels of the
same diameter and thickness to stand between them, so that the cranks may
go round without moving the other wheels marked C, and E; and the
wheels D and F on the cranks A, A, in the Drawing No. 4, being made fast
on the cranks A, A, by means of a screw or pin, and the wheels C and E,
being fixed close together, slide to and fro upon a square end of the axle
marked U in the Drawing No. 4, by the means of a guide or sliding gear
marked V in the Drawing No. 4, which is fixed in a groove turned out of the
nave of the wheel E, by means of a clip and two screws which fastens it under-
neath, and rests in the notches fixed at the other end of the box or frame for the
end of the guide or geer to rest in. The notches are three in number, on each
side of the box or frame marked W in the Drawing No. 4; the one farthest
from the wheel has the guide V drawn back with the wheel marked E upon
the small wheel marked F; by moving the guide into the middle notch keeps
the wheels C and E between the wheels D and F, and the notch nearest the
wheels guides the wheel C on the large wheel D, so that the power is much
greater when forcing or drawing water from a greater depth, when the
wheels C and E are placed in the space between the lower wheels. I then move
the handle from the upper axle U, and place it upon the end of the crank A, A,
and work without the assistance of the wheels as occasion may require. I
further furnish this machinery with four key bow rods marked B, B, B, B, in
the Drawing No. 4, for the purpose of fixing the spear boxes or blunging rods
to, by means of a joint and pin or bolt, the key bow being filed square across
in the inside, so as to give the rolling step a fair bearing.

page_text: I do also claim as my Invention the following mode of making the rolling
step marked Y and X in the Drawing No. 5 --I form two pieces of brass,
the one half round and the thickness according to the strength or size of the
machinery, and the other round like a wheel or sheave in form, of the same
thickness as the other half. I then cut this round sheave or wheel half
through the middle edgeways. I then cut that piece off and cut a dovetail
down the width in proportion to the crank. I then fit the other half into the
place where I have cut out of the larger piece, and hold them together by
means of two screws. This being done, the sheave or wheel then bears the
form of its first appearance before being cut. I then drill a hole through the
centre of it, and place it upon the before-mentioned crank or cranks. This
being done, and fitted together in a proper manner, the Drawing No. 5,
marked Y, represents the larger half of this step, and the Drawing marked X
represents the smaller half, with the dove-tailed piece standing upon it, which
fills up the vacancy or room that is made in the large half for fixing it upon
the cranks.
screws.
I also claim the following as my particular mode of forming the key bow
rod, it being made in so simple a manner, the ends of each bow being set in
the grooves 0, 0, 0, 0, in the Drawing No. 4, and the key bow rods marked
B, B, B, B, work through holes in the bottom of the box, for which purpose
I have formed an iron plate or bar, with four holes, as marked S, S, S, S, in
the Drawing No. 6, which I fix to the bottom of the box or frame with
The rods being fitted into the holes in this plate keep the stroke of
the pump perpendicular, while the step rolls to and fro in the key bow as they
are forced up and down by the cranks moving or turning alternately round.
When this machinery is made use of over a forcing pump, or placed upon a
fire engine, it causes a greater quantity of water to be discharged from the
cistern or engine; and it being so powerful, it is highly necessary it should
have a cock of a superior size to let more water pass through in the same
time than ordinary. I have for this purpose invented a cock which will admit
a great deal more water than any other that has been made for the purpose.
I therefore claim as my Invention the formation of this cock. I make the
barrel, or part of the cock where the key or stop goes in, all to one side.
This being done, I have but one stop to the plug or key. The stop resting in
that part that overhangs the side, admits of room for a full-sized waterway to
be completely through it without causing the water to have any bubble or curl
as it passes through the plug.
The Drawing No. 1 represents the side view of the cock. The Drawing
No. 2, a top view of the cock; and the Drawing No. 3, the plug with the

In witness whereof, I, the said William Tyror, have hereunto set my
hand and seal, this Fifth day of May; in the year of our Lord One
