page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN THE CONSTRUCTION OF NAVES OR BOSSES FOR WHEELS."-A communi→

PROVISIONAL SPECIFICATION left by the said Richard Archibald.
Brooman at the Office of the Commissioners of Patents, with his.
Petition, on the 2nd March 1860.
.I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF NAVES OR BOSSES FOR WHEELS,"
(communicated to me from abroad by Gustave Hamoir, of Saultain, France,)
to be as follows:-
This Invention consists in forming upon the outside of a box or tube
cylindrical or conical on the inside, according to the form of the journal of the
axle or of the shaft on which it is to be placed, two discs at right angles, or
nearly so, to the outer surface of the box. The inner ends of the spokes pass'
between these discs, and rest upon the box, where they are secured by the
discs being drawn and held together so as to press so much of the ends of the
spokes as is contained between them. One dise may be cast or otherwiso

formed in a piece with the box, and the other may be a separato piece of
metal with a hole through the centre to slip over the box, the movable disc
being drawn towards the stationary disc by means of screw bolts and nuts, or
otherwise; or both discs may be movable, and may be made to approach each
other, and hold the spokes by means of screw threads. Where the spokes
are to be fitted into the nave at an angle, the inside of the discs is so shaped
as to admit them at the required angle. The spaces between that portion of
the spokes comprised within the discs are filled up with blocks of wood. The
inner surfaces of the discs may be grooved. or serrated to give them a better
bite upon the spokes, but this has not been found necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 1st September 1860. :
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Second day of March, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her

said Richard Archibald Broonian, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, 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 "IMPROVEMENTS IN THE CONSTRUCTION OF NAVES OR BOSSES FOR WHEELS,". (a
communication from abroad by Gustave Hamoir, of Saultain, France,) upon the
condition (amongst others) that I, the said Richard Archibald Brooman, 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 per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six. calendar monthis next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same 'is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed (that is to say):-
:
This Invention consists in forming upon the outside of a box or tubo
cylindrical or conical on the inside, according to the form of the journal of the
axle or of the shaft on which it is to be placed, two discs at right angles, or
nearly so to the outer surface of the box. The inner ends of the spokes pass
between these, discs and rest upon the box, where they are secured by the
discs being drawn and held together, so as to press so much of the ends of the
spokes as is contained between them. One disc may be cast or otherwise
formed in a piece with the box, and the other may be a separate piece of
metal with a hole through the centre to slip over the box, the movable disc
being drawn towards the stationary disc by means of screw bolts and nuts,
or otherwise; or both discs may be movable, and may be made to approach
each other and hold the spokes by means of screw threads. Where the
spokes are to be fitted into the nave at an angle, the inside of the discs is so
shaped as to admit them at the required angle. The spaces between that
portion of the spokes comprised within the discs are filled up with blocks of
wood. The inner surfaces of the discs may be grooved or serrated to give
them a better bite upon the spokes, but this has not been found necessary.
Figure 1 of the accompanying Drawings is a longitudinal section of the
nave or boss of a wheel constructed according to this Invention; Figure 2 is
a plan of a portion of the same; and Figure 3 is a transverse section showing
the manner in which the spokes are fitted into the nave. E, E, (Figure 3)
are wedges or blocks of wood filling the spaces between the inner ends of the
spokes and taking the bearing of the shoulder D formed on the spokes C.
The shape of the opening between the inner ends of the spokes prevents the
wedges, after being inserted therein, from being jolted out by the motion of
the wheel. The ends C' of the spokes meet together at the part marked F,
and afford a mutual support to one another. The wood is made sufficiently
thick, in order that when the spokes are in position their inner ends shall not
touch the outside of the box. The upper ends of the wedges project a short
distance beyond the discs H and H'; when the tyre is applied the shrinking
of the metal in cooling tightens up all the parts. The second disc H' is con-
nected to the first H by four or a greater number of rivets or bolts a. The
two discs are constructed in such manner as to give to the wheels the
necessary inclination. The first disc H is made in a piece with the nave, as

page_text: shown in the Drawing, or it may be made independent of the nave, and after-
wards connected to it. In a similar, manner the disc H' can be made of any
other suitable form than that shown.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the construction
of naves or bosses for wheels; by forming on or connecting to the box two
discs between which the spokes are held, essentially in the manner herein-
before described and illustrated in the accompanying Drawings.
.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and scal, this First day of September, One thousand
eicht hundred and sixty.
R. A. BROOMAN. (L.s.)
