Year: 1857

page_text: LETTERS PATENT to John Smith, of Bradford, in the County of York,.
Machine Maker, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS USED IN THE MANUFACTURE OF BRUSHES FOR FLOUR DRESSING
MACHINES."
Sealed the 29th September 1857, and dated the 3rd April 1857.
PROVISIONAL SPECIFICATION left by the said John Smith at the Office
of the Commissioners of Patents, with his Petition, on the 3rd April
1857.
I, JOHN SMITH, of Bradford, in the County of York, Machine Maker, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
OR APPARATUS USED IN THE MANUFACTURE OF BRUSHES FOR FLOUR DRESSING
MACHINES," to be as follows:-
I place or distribute the bristles on a board or platform made in two parts
longitudinally of the length the brush is required to be made. I then
transfer the said board or platform with the bristles upon it to the surface of a
machine, which has a longitudinal slot or groove formed by a moveable jaw.
The bristles being placed across the said slot or groove transversely, I pass a
cord or band over them parallel with and over the slot or groove; a bar or
blade is then caused to descend upon the cord or band, and press it with the
bristles partially into the slot; the board or platform is then withdrawn, and
glue is introduced into the gutter thus formed by the bar or blade, which bar
is then further pressed down into the slot until the bristles are doubled up at

page_text: each side of the bar, and by means of the moveable jaw are held in that
double position until the bar or blade is withdrawn. A pair of clams are then
applied to the whole length of the bristles, and tightened up to secure and
keep them in the same position to be removed from the machine. I then
form another row or length of bristles, same as aforesaid, and made in the same
manner; the two rows or lengths are then placed together with the root ends
outwards and the flag inwards. The two rows or lengths of bristles are then
placed in grooved stocks made of two or more parts, which are laid in a press
and pressed together sufficiently tight to be screwed or fastened permanently.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Smith in the Great Seal Patent Office on the
2nd October 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SMITH, of Bradford, in the County of York, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of April, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Smith, Her special license that I, the said John Smith, my
executors, administrators, and assigns, or such others as I, the said John
Smith, 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 MACHINERY OR
APPARATUS USED IN THE MANUFACTURE OF BRUSHES FOR FLOUR DRESSING MACHINES,"
upon the condition (amongst others) that I, the said John Smith, by an
instrument in writing under my hand and seal, 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 John Smith, 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):-

page_text: I place or distribute the bristles on a board or platform made in two parts
longitudinally of the length the brush is required to be made. I then transfer
the said board or platform with the bristles upon it to the surface of a machine,
which has a longitudinal slot or groove formed by a moveable jaw. The
bristles being placed across the said slot or groove transversely, I pass a cord
or band over them parallel with and over the slot or groove; a bar or blade is
then caused to descend upon the cord or band, and press it with the bristles
partially into the slot. The board or platform is then withdrawn, and glue is
introduced into the gutter thus formed by the bar or blade, which bar is then
further pressed down into the slot until the bristles are doubled up at each
side of the bar, and by means of the moveable jaw are held in that doubled
position until the bar or blade is withdrawn. A pair of clams are then
applied to the whole length of the bristles, and tightened up to secure and
keep them in the same position to be removed from the machine. I then
form another row or length of bristles, same as aforesaid, and made in the
same manner. The two rows or lengths of bristles are then placed together
with the root ends outwards and the flag inwards in grooved stocks made of
two or more parts, which are laid in a press and pressed together sufficiently
tight to be screwed or fastened permanently.
But in order that my Invention may be clearly understood, I have given
reference to the accompanying Sheet of Drawings. The same letters refer to
the same parts in each Figure.
Figure 1 is a plan of a portion of the board or platform in two parts A, B,
on which are distributed the bristles, the root ends being placed to the fence
on the board A; Fig. 2 is an end view of the same, with a slip C of the same
length placed upon the part A, which together form a clam, by means of
which the bristles can be removed from the part B to the bending machine.
Figure 3 is an end elevation, Figure 4 is a front elevation, and Figure 5 is a
plan, of the bending machine, to which I transfer the bristles for bending or
doubling them.
D is a fixed jaw; and E is a moveable one, operated by the
screws F and bevil gear wheels G by means of the handle H. The nipping
edges of the jaws are indented or toothed. Figs. 6 and 7 are full size views of
parts of Figs. 3 and 4; Figs. 8 and 9 are end and side views of the clams, which
have bolts passing through them, with wing nuts outside and spiral springs
inside. Fig. 10 is a cross section of the wood stocks, in two parts, prepared to
receive the bristles; Fig. 11 is an end elevation; Fig. 12 is a front elevation;
and Fig. 18, a plan of the press. Figs. 14 and 15 are views of a complete
brush, the stock in three parts. The bristles are laid or placed across the slot
or groove formed by the two jaws, as seen at Fig. 6, the board A forming a

page_text: guide for placing them. A band or cord is then strung across the bristles
over and parallel with the groove, and the slip C is removed. The bar
or blade I is then forced down upon the cord by means of the bevil gear
wheels J and screws K pressing the bristles partially into the groove; the
moveable jaw is then brought forward and glue laid in the gutter thus formed
(as will be seen by dotted lines) along the side of the blade, which is then
forced down to the bottom of the groove and the movable jaw moved close up
to the blade, whereby the bristles are doubled up on each side of the blade,
which bar or blade is then withdrawn and the moveable jaw again screwed up.
The frame L which carries the blade is then turned back upon its hinges M. to
allow the clams to be applied to the bristles for removing them from the
groove, which is laid aside until another row of bristles is formed in the same
The two rows of bristles are then placed in or betwixt the wood
stocks which have been previously prepared as at Fig. 10, and then put in the
press and pressed close together, screws being inserted whilst in the press at
each opening N, as seen at Fig. 12, to secure the brush permanently
together.
Having thus fully described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that I claim as my Invention the combination and arrangement of
machinery or apparatus for the manufacture of brushes in the manner and for
the purposes as herein described, and illustrated in the accompanying Sheet
of Drawings, or any modification thereof.
In witness whereof, I, the said John Smith, have hereunto set my hand
and seal, this First day of October, in the year of our Lord One
thousand eight hundred and fifty-seven.
Signed, sealed, and delivered by the within-
named John Smith, in the presence of
W TASKER, Patent Agent,
Halifax.
JOHN SMITH. (L.S.)
