and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF WHEELS FOR CARRIAGES;" in which said Letters Patent
is contained a proviso, that I, the said William Gilmour Wilson, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in Her said Majesty's High Court.
of Chancery within six calendar months next and immediately after the date;
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Gilmour Wilson, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawings. hereunto annexed, and to the figures and letters
marked thereon, that is to say:
DESCRIPTION OF THE. DRAWINGS.
Figure 1 is a front or outside view of a wheel constructed according to my
Invention. A. is the nave. or. centre; B, the arms or spokes; C, the rim;
D, D, the sockets or couplets for joining the naves and rims together.
Figure 2 is a cross section of the wheel, at the red line a, b, on Figure 1.
Figure 3 is a section of the wheel, at the red line c, d, in Figure 2. The
wrought iron, or other wrought metal, is to be formed by means of rollers,
or other means, into a hollow shape, as shown, and the ring may be of one,
two, or more pieces. A; nave or centre, which is formed of plates fastened
together by ordinary means, or it may be cast in one or more pieces. The
outside is kept close, so that neither the bush nor the end of the axle comes
through. to. the outside. On the inner side of nave or centre is a snugg or a
flange, by which a plate is fastened to the nave, and presses against the collar
of the axle, so as to keep the axle in the nave and bush. A section-of-the
flange is shown in Figure: 2, as also in details at h, h, and a face-view of the
same is shown in details at r. The plate is shewn on Figure 2 at J, J; and
a face in details at K; and B, B, are the spokes or arms; they are formed of
holfo tubes of iron, or other metal, and they may be filled with wood, so as
to lessen the sound of the wheel while running, and also to give strength to
the spokes. D, D, are sockets or couplings for fastening the spokes to the
nave and rim. The sockets may be formed of iron or other metal, as shewn
at Figures: 1, 2, and 3, as also in details at d, e; these sockets are fastened to
the rim and nave by rivets, bolts, screws, or other ordinary means. The
hollow rim. C. may be completely or partially filled with wood or other strong
light substance, so as to lessen the sound of the wheel while running, and give
stiffness to the hollow rim, as also to form a suitable bearing or bed-for the
hoops or tires, which forms: the wearing part of wheel; this wood or other
substance may also be studded with nails, wedges; or bolts made of iron or
other hard metal, so as to form the wearing part of rim, and in this way
dispense with a hoop or tire. A view of this part is shewn in details at g..
Having thus described the nature of my Invention; and the best-means-I

page_text: am acquainted with for performing the same, I would have it understood that
what I claim is,-
First, the mode of forming the hollow rim or felloe of a wheel by means of
wrought iron or other rolled metal.
Secondly, I claim the mode of fixing the spokes to the nave and to the rim
or felloe by means of sockets, as described. ..
And, thirdly, I claim the mode of forming the nave as shown in the
Drawings.
In witness whereof, I, the said William Gilmour Wilson, have hereunto
set my hand and seal, this 22nd day of October, in the year of our
Lord One thousand eight hundred and forty-five.
WILLIAM GILMOUR (L.B.) WILSON.
