Year: 1827

page_text: LOCKYER, of the City of Bath; Brushmaker, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-eighth day of April, One thousand eight hundred
and twenty-seven, in the eighth year of His reign, did for Himself, his heirs
and successors, give and grant unto me, the said William Lockyer, His
especial licence that I, the said William Lockyer, my exors, admors, and
assigns, or such others as 'I, the said William Lockyer, my exors, admiors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT IN THE MANU-
FACTURE OF BRUSHES OF CERTAIN DESCRIPTIONS, AND IN THE MANUFACTURE OF A
MATERIAL OR MATERIALS AND THE APPLICATION THEREOF TO THE MANUFACTURING
OF BRUSHES, AND OTHER PURPOSES;" in which said Letters Patent is contained
à provisó, obliging me, the said William Lockyer, by an instrument in writing
under my hand and seal, particularly to describo and ascertain the nature of
my said Invention, and in what inanner the same is to be performed, and to
cause the same to be inrolled in His 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 Lockyer, do declare that my improvement is on brushes for plasterers*
uses, commonly called "stock brushes," and my method of manufacturing
them is as follows:-
I take a piece of elm or other wood and reduce it to about the thickness of
one and a quarter inch and to ten inches wide, or thereabouts, according to the
work to which it is to be applied, and the length of the handle may be varied
to suit the taste of the manufacturer; I then bore (see Drawing annexed) the
holes about half an inch deep and about one-eighth part of an inch diameter.
I chiefly use Glascotts bitts for this purpose. Having bored the holes, I take
bristles or other suitable materials, and confine by tying or otherwise fastening
them, previously having dipped them into the material, hereafter to be described,
to unite the bristles or other materials into knots; these knots I dip a second
time into the material, hereafter described, and pass them up the holes previously
bored to receive them, the cement causing them to be permanently fixed in the
holes; I have founed tying the bristles or other materials to suit my purpose
best; round the rim of the brush, thus formed, I nail a slip of zinc of from
three-quarters of an inch to one inch wide, placing it so that about one half the
width of the zinc shall rest on the wood and the remaining half, or thereabouts,
on the bristles or other materials. When the zinc is so nailed on I press it
gently inwards towards the bristles or other materials; this causes the brush to
work very clean and prevents it splashing; they will be found to be more
durable and superior brushes than those at present used by plasterers. Other
materials may be used to go round the rim of the brushes, such as copper, tin,
brass, iron, or even leather, but I have found zinc to answer best. The
material or materials consist of a mixture of about seven-eighth parts of pitch
and one part eighth of shellac, to be melted over a slow fire and well mixed,
when it will be in a proper state for being applied to fastening of the bristles or
other materials into the handle or stock of the brush. Other proportions may
be used, but I have found this to suit the purpose; and other materials may be
mixed with the pitch and shellac to produce a cement, but I have found the
above described to suit my purpose.
I claim the application of my improvement first described to plasterers'
brushes, commonly called "stock brushes," whether made with my improved
cement or with any other, and also the cement above described.
In witness whereof, I, the said William Lockyer, have hereunto set my
hand and seal, this Twenty-second day of October, in the year of our
Lord One thousand eight hundred and twenty-seven.
WILLIM
(L.S.) LOCKYER.
