Year: 1811

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TAYLOR, of Greenwich, in the County of Kent, Esquire, send greeting.
WHEREAS His present most Excellent Majesty King George the Third,
in and by His Royal Letters Patent under the Great Seal of the United
Kingdom of Great Britain and Ireland, bearing date at Westminster, the
Eleventh day of April, in the fifty-first year of His reign, for Himself, His
heirs, and successors, did give and grant unto me, the said John Taylor, my
executors, administrators, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said John Taylor, my executors, adminis-
trators, and assigns, by myself and themselves, or by my and their deputy or
deputies, servants or agents, or such others as I, the said John Taylor, my
executors, administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within that part of His said Majesty's United Kingdom called England,
the Dominion of Wales, and Town of Berwick-upon-Tweed, my Invention
of CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS FOR CARRIAGES
OF DIPPERENT DESCRIPTIONS;" in which said Letters Patent there is contained a

page_text: proviso, obliging me, the said John Taylor, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my said
Invention, and the manner in which the same is to be performed, and to cause
the same to be inrolled in His said Majesty's High Court of Chancery within
two calendar months next and immediately after the date of the said recited
Letters Patent, as in and by the same, reference being thereto had, will more
fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Taylor, do hereby describe and ascertain the nature of my said Invention,
and the manner in which the same is to be performed, by the Drawings here-
unto annexed, and as follows, that is to say :-
My Invention consists of an apparatus applicable to the wheels of carriages
of different descriptions, which is so constructed as to facilitate and render secure
the mode of fastening the box into the stock of the wheel, and the wheel on
the axletree, and to loosen or tighten the wheel on the axletree as circum-
stances or convenience may require, to reduce friction and prevent stickage;
and also in supplying such apparatus with oil without taking off the wheel
from the axletree, and in such a proportion or quantity as to render the neces-
sity of a supply not more than once or twice per year. My Invention likewise
consists of a spanner, for the purpose of fixing on and taking off the wheel from
the axletree; which spanner is composed of three parts, one for fixing and
unfixing the wheel, another to convey the oil into the box of the wheel, and
the other for cleaning out the hole in the arm. A in the annexed Drawing
represents the box to be made of iron, brass, bell metal, or any mixture of
metals of a texture hard enough to resist the friction of the arm, and of such
dimensions as to fit the arm tight, being solid at the end so as to prevent the
oil from escaping; at the small end of the box is a screw, and an inverted
point may be added if required (N° 1) for the purpose of being fastened into the
stock by means of a nut. No 2, the large end of the box of a circular shape
(with a screw inside) of a circumference sufficient to receive the flanch of the
arm, and the half nuts by which it is fastened on. No 3, the hole, of sufficient
space to admit the oil to pass freely into the box. In the large end of the box
at the extremity are shewn the grooves, of which there should be a sufficient
number to allow the wheels to be fastened tighter or looser, as may be required,
by means of two clickers, or stops, or pins in the half nuts.
B, the arm, of
cylindrical or conical shape, to which a bead may be attached for the purpose
of keeping it steady if required with a flanch, N° 4, which supersedes the
linch pin, and should be welded upon the arm in its proper position, so as to

page_text: fit the shoulder end of the box on the front side, and of such thickness as to
resist the pressure and friction of the half nuts, which are fixed behind it.
N° 5, a continuation of the arm behind the flanch for the half nuts to run upon,
with sufficient room for putting on the wheel, and a hole for the admission of
air into the reservoir, which is grooved for the purpose of supplying the half
nuts with oil. In the Drawing B, are introduced the half nuts, merely to
shew their proper position when fixed; on the arm behind the flanch the
dotted lines in the arm shew the communication between four holes for the
purpose of receiving, holding, and circulating the oil which enters at the hole
No 6 on the top of the flanch, passes from thence into the reservoir formed in
the arm, and circulates at the holes N° 7, and 8, and 9. C, section of the half
nuts, back view, representing the holes for the spanner N° 1, 1, and the screws
2, 2, which fasten to clickers; D, the clicker or stop, consisting of a pin of
iron, steel, or metal, of about one-fourth the length of the arm, with two
grooves, the smallest N° 3 for the point of the spanner when applied to
hole No 1 in the half nuts; N° 4, the other groove made larger for the
reception of the screw with which it is confined in the half nut, see N° 2; in
the half nuts under which screw the clicker must be allowed to move easily
when the spanner is applied by means of the screw being made small enough and
smooth at the centre part, as represented in the section E; F, the worm spring,
which being placed at the bottom of the hole occupied by the pin stop or clicker
in the half nut, forces or propels the said pin stop or clicker into the grooves of
the box, and thereby acts or operates as a spring stop, and prevents the half
nuts from turning in the thread of the screw when fixed; G, the spanner;
No 1, the end part for cleaning out the hole in the arm; N° 2, the funnel for
conveying the oil into the box, &c., which funnel being hollow receives the
end part No 1, and fastens with a snap spring at the hilt end, and these two
parts so united are received by the barrel of the spanner; No. 3, the forked
or clip end of the spanner, see letter H (representing the spanner entire),
fastens on the bed of the axle treeclose behind the nave of the wheel by
means of the screw N° 4; N° 5, 5, are the points at the extremity, for the
purpose of fixing and unfixing the wheel; N° 6, 6, points for fixing and unfix-
ing the screw nut on the front of the box occasionally to be introduced as
ornamental to the wheel.
In witness whereof, I, the said John Taylor, have hereunto set my
hand and seal, this Tenth day of June, in the year of our Lord One
thousand eight hundred and eleven.
JOHN TAYLOR. (L.S.)
