Year: 1868

page_text: ETTERS PATENT to Marc Antoine François Mennons, of the Firm
of Mennons and Telescheff, Home and Foreign Patent Agents, of
No. S, Southampton Buildings, in the County of Middlesex, and
53, Rue de la Chaussée d'Antin, Paris, in the Empire of France,
for the Invention of "AN IMPROVEMENT IN CERTAIN DESCRIPTIONS OF
BRISTLE BRUSHES."-A communication from Thomas Maury, residing
at Washington, in the United States of America.
Sealed the 4th August 1868, and dated the 21st February 1868.
PROVISIONAL SPECIFICATION left by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition, on the 21st February 1868.
I, MARC ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and
Telescheff, Home and Foreign Patent Agents, of No. 8, Southampton
Buildings, in the County of Middlesex, and 53, Rue de la Chaussée
d'Antin, Paris, in the Empire of France, do hereby declare the nature
of the said Invention for "AN IMPROVEMENT IN CERTAIN DESCRIPTIONS
OF BRISTLE BRUSHES" (a communication) to be as follows:-
This improvement consists in rounding off to a blunt point the
angular extremities of the bristles of certain descriptions of brushes,

page_text: thereby substituting a smooth and polished surface to the harsh and
irritating asperities of ordinary brushes. To this end the face of the
manufactured brush is submitted to a grinding process, which may be
performed by a hard close grained grindstone, and is thereafter polished
off by a wheel armed with bristles similar to those employed by dentists.
The grindstone used in this process may be either circular or flat, a
horizontal to-and-fro motion being in the latter case imparted to the
slab by any suitable mechanism. For serrated brushes a number of
thin V-edged discs or slabs, formed preferably of corundum or other
known whetstone composition are mounted face to face on a central
bar, or otherwise clamped together, so as to present a corrugated surface
corresponding with that of the brush, but this arrangement when so
desired may be replaced by a single stone with moulded ridges of the
required depth and form; the serratures being formed by this apparatus,
the longer bristles are grained to the required extent on the plane faced
stone in the same manner as the plain or oval faced brush. The
polishing and finishing is effected as before stated by a revolving
wheel armed with bristles, which at same time remove all the powder
which may have accumulated in the brush during the grinding process.
The improvement above described may be applied to nearly every
description of hogs'. bristle, brushes, but will be found more especially
useful in tooth, hair, nail, flesh, cloth, horse, and other brushes of like
class.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Marc Antoine François Mennons in the Great Seal
Patent Office on the 11th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANCOIS MENNONS, of the Firm of Mennons and Telescheff,
Home and Foreign Patent Agents, of No. 8, Southampton Buildings, in
the County of Middlesex, and 53, Rue de la Chaussée d'Antin, Paris,
in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

page_text: give and grant unto me, the said Marc Antoine François Mennons,
Her special licence that I, the said Marc Antoine François Mennons,
my executors, administrators, and assigns, or such others as I, the
said Marc Antoine François Mennons, 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 of "AN IMPROVEMENT IN CERTAIN DESCRIPTIONS
OF BRISTLE BRUSHES," (a communication from Thomas Maury, a person
resident at Washington, in the United States of America), upon the
condition (amongst others) that I, the said Marc Antoine François
Mennons, 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 monthis next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Marc Antoine François Mennons,
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, that is to say:-
This improvement consists in rounding off to a blunt point the
angular extremities of the bristles of certain descriptions of brushes,
thereby substituting a smooth and polished surface to the harsh and
irritating asperities of ordinary brushes. To this end the face of the
manufactured brush is submitted to a grinding process, which may be
performed by a hard close grained grinding stone, and is thereafter
polished off by a wheel armed with bristles similar to those employed
by dentists. The grindstone used in this process may be either circular
or flat, a horizontal to-and-fro motion being in the latter case imparted
to the slab by any suitable mechanism. For serrated brushes a number
of thin V-edged dises or slabs, formed preferably of corrundum or other
known whetstone composition, are mounted face to face on a central
bar, or otherwise clamped together so as to present a corrugated surface
corresponding with that of the brush, but this arrangement when so
desired may be replaced by a single stone with moulded ridges of the
required depth and form; the serratures being formed by this apparatus,

page_text: the longer bristles are ground to the required extent on the plane
faced stone in the same manner as the plain or oval faced brush.
The polishing and finishing is effected as before stated by a revolving
wheel armed with bristles, which at same time remove all the powder
which may have accumulated in the brush during the grinding process.
The improvement above described may be applied to nearly every
description of hogs' bristle brushes, but will be found more especially
useful in tooth, hair, nail, flesh, cloth, horse, and other brushes of like
class.
Having now described and ascertained the nature of the said
improvement, and the manner in which it may be carried into
effect, I declare that what I claim, and desire to secure by Letters
Patent. is, the rounding off to a blunt point of the angular extremitics
of the bristles of tooth, hair, nail, flesh, cloth, horse, and other brushes of
like class, thereby substituting a smooth and polished surface to the
asperities of ordinary brushes, the said rounding off being effected by
grinding or other equivalent process, substantially as above described.
In witness whereof, I, the said Marc Antoine François Mennons,
have hereto set my hand and seal, this Tenth day of August,
in the year of our Lord One thousand eight hundred and
sixty-eight.
