IMPROVEMENTS IN THE GEARING OF MOWING AND OTHER LIGHT PORTABLE MACHINES
Year: 1860

page_text: LETTERS PATENT to William Manwaring, of Banbury, in the County of
Oxford, Engineer, for the Invention of "IMPROVEMENTS IN THE GEARING
OF MOWING AND OTHER LIGHT PORTABLE MACHINES."
Sealed the 17th May 1861, and dated the 23rd November 1860.
PROVISIONAL SPECIFICATION left by the said William Manwaring
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd November 1860.
I, WILLIAM MANWARING, of Banbury, in the County of Oxford, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
GEARING OF MOWING AND OTHER LIGHT PORTABLE MACHINES," to be as
follows:-
My Invention is intended to avoid noise and secure durability in the gearing
of machines of the above class, in which space is limited, and it consists in con-
structing one or both wheels (but by preference one only) in any pair or pairs
of wheels gearing into each other, as follows:-
I take two metal discs, having opposite and corresponding recesses or per-
forations in or through their faces near the periphery arranged in a circle at
equal distances from each other and from the centres of the discs, and I connect
such discs by means of teeth or pins of wood, or of any other non-metallic com-
pressible substances, driven tightly into such recesses or perforations, bracing
the discs together by bolts or cottars, or other well known fastening, if required.

page_text: Each pair of discs so constructed will form a toothed or tumbler wheel, and is
used to gear into another wheel of similar or of any other (by preference of the
ordinary construction.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Manwaring, in the Great Seal Patent Office on
the 22nd May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MANWARING, of Banbury, in the County of Oxford, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of November, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Manwaring, Her special licence that I, the said William
Manwaring, my executors, administrators, and assigns, or such others as
I, the said William Manwaring, 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 GEARING OF MOWING AND OTHER LIGHT PORTABLE
MACHINES," upon the condition (amongst others) that I, the said William
Manwaring, 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 William Manwaring, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention is intended to avoid noise and secure durability in the gearing
of machines of the above class, in which space is limited, and it consists in
constructing one or both wheels (but by preference one only), in any pair or
pairs of wheels gearing into each other, as follows:-
I take two metal discs, baving opposite and corresponding recesses or per-

page_text: forations in or through their faces near the periphery arranged in a circle at
equal distances from each other and from the centres of the discs, and I connect
such discs by means of teeth or pins of wood, or of any other non-metallic com-
pressible substances, being either driven in, wedged, or otherwise secured by
any known means; but I prefer simply to drive them into such recesses, the
discs being also braced together by bolts or cottars, if required. Each pair of
discs so constructed will form a toothed or tumbler wheel, and is used to gear
into another wheel of similar or of any other (by preference of the ordinary)
construction.
The accompanying Drawing represents the mode of constructing gearing
according to my Invention, which I prefer.
Figures 1 and 2 are respectively a section and a plan of my improved wheel.
The dotted lines a, a¹, a", and so on in the latter show the position of the teeth
and the recesses, which may be of any other shape, as, for instance, round,
oval, &c.; the dotted lines b, b', in the same figure, and the parts similarly
marked in Figure 1 represent the boss which keeps the two discs at the proper
distances from each other, and through which the bolts or other fastenings
c, c¹, c", connect or brace the said discs together; d is the eye of the wheel in
which the axle is keyed; e, e', are the two discs; f, f¹, f", f, the recesses in
the same, and g', g, two of the teeth driven into such recesses.
I claim as my Invention the construction of gearing wheels for mowing, and
other light portable machines, in the manner and on the principle herein-
before stated.
In witness whereof, I, the said William Manwaring, have hereunto set
my hand and seal, this Twenty-first day of May, One thousand eight
hundred and sixty-one.
Witness to the signature,
JOHN SHAW, Engineer,
Banbury.
WILLIAM MANWARING. (L.S.)
