page_text: LETTERS PATENT to Joshua Blow, of Carden Road, Nunhead, in the County
of Surrey, Factory Manager, for an Invention of "IMPROVEMENTS CONNECTED
WITH DISTRIBUTING PASTE,COLOUR, SIZE, OR OTHER LIKE ADHESIVE UPON
PAPER OR OTHER FABRICS."
PROVISIONAL SPECIFICATION left by the said Joshua Blow at the Office of
the Commissioners of Patents on the 7th February 1880.
JOSHUA BLOW, of Carden Road, Nunhead, in the County of Surrey, Factory
Manager. "IMPROVEMENTS CONNECTED WITH DISTRIBUTING PASTE, COLOUR,
SIZE, OR OTHER LIKE ADHESIVE UPON PAPER OR OTHER FABRICS."
This Invention relates to improvements connected with distributing paste, colour,
size, or other like adhesive upon paper or other fabrics, and consists in an arrange-
ment of brushes or felts set at suitable angles above and below the pasting table to
spread or distribute the paste or other adhesive evenly and uniformly upon the
surface or surfaces.
The brushes are preferably of cylindrical form, and mounted in bearings which
are adjustable by set screws to determine the amount of pressure or frictional
contact for passing the paper from the pasting drums to the attendant.
The inner end of one brush of each pair (there being two below and two above)
is slightly in advance of the inner end of the other brush, and in opposite positions
that a straight line of motion is given to the paper in its passage.
A series of parallel brushes are in most cases arranged behind the angled brushes
or felts to receive the paper and convey it to the attendant stationed at any distance
from the pasting machine.
The angled brushes are rotated at a speed proportionate to that of the pasting
drums, and their action distributes the paste evenly and uniformly upon both sides
of the paper, or upon one side only if desired, that the tree marks" left by the
pasting drums are destroyed, superfluous paste removed, and plain clean surfaces
produced.
The action of the angled brushes or felts effect a better pasting of the paper, and
a more solid pasteboard is the result.
I have described the Invention as applied to the usual pasting machine used in
the making of pasteboards, but it is applicable to other machines, such as those
where colour or size is spread upon papers and other fabrics.

JOSHUA BLOW, of Carden Road, Nunhead, in the County of Surrey, Factory
Manager. "IMPROVEMENTS CONNECTED WITH DISTRIBUTING PASTE, COLOUR, SIZE,
OR OTHER LIKE ADHESIVE UPON PAPER OR OTHER FABRICS."
The object of this Invention is apparatus to be attached to pasting, sizing, or
colouring machines, whereby an even and uniform distribution of and the removal
of superfluous liquid or semi-liquid substance is effected upon the paper or other
fabric after it has left the pasting drums, the result being an entire absence of
" tree marks," and the production of a clear plain surface of the fabric on one or
on both sides, as desired.
The apparatus shown in the annexed Drawings consists essentially of two pairs
of cylindrical brushes A, A¹, B, B¹, (hair or felt covered) set at opposite angles,
between which the fabric is caused to pass after leaving the pasting or sizing drums
C, C, the fabric being led to the brushes by strings and rollers D, D. Each pair
of cylindrical brushes A, A¹, B, B¹, are geared at Ĕ, E, to slightly draw the fabric
in between them, and to pass it on to other rotating rollers F, F, towards an
attendant stationed at G to receive the sheets in succession. The brushes F, F, are
actuated by pinions H, H, on their axles I, I, gearing into the wheels J, J, which
receive their motion by a strap pulley K from any suitable part of the pasting
machine.
In the Drawing, Figure 1, which shows a pasting machine complete with my
distributing apparatus affixed, the strap L for operating on the pulley K is driven
from a rigger fastened to cog wheel of pasting machine; K¹ is the driving shaft
with cog wheel M to work into J, J, which are in a piece with or mounted on the
same axles as the wheels J, J, and the bevilled wheels N, N, which produce the
desired speed of rotation of the lower cylindrical brushes A', B', of each pair by
the gearing E, E, the upper cylindrical brushes A, B, obtaining their rotation
from the gear wheels, as clearly shown by the plan, Figure 2, and by the perspective
view, Figure 3.
Behind the rollers F, F, are a number of other rollers R, R, which get their
rotation from the axles P, P, through the intermediate pinions S, S. These rollers
may be increased or diminished in number as desired, their purpose being to carry
the fabric to the attendant only.
The speed of rotation of the angled cylindrical brushes A, A¹, B, B', is in excess
of the travel of the fabric through the pasting, sizing, or colouring machine, and
they consequently exert a brushing action upon it, which not only distributes
the substance evenly and uniformly upon the surface or surfaces, but removes the
superfluous portion, and destroys all lines or "tree marks" left upon the fabric by
the pasting drums.
The degree of frictional contact of the brushes A, A¹, B, B¹, upon the fabric can
be regulated by the tightening nuts and set screws T, T, for adjustment for different
thicknesses of fabric.
It will be seen (more particularly) by the plan view, Figure 2, that the pairs of
angled brushes are of different lengths, that the inner end of one pair B, B¹, come
beyond the inner end of the other pair A, A', that no line of division be left by
them upon the fabric.
Having now described the nature of my said Invention and in what manner the
same is to be performed, I declare that I claim,-
The apparatus consisting of two pairs of brushes of different lengths arranged at
opposite angles, as shown in the annexed Drawings, for evenly and uniformly

page_text: distributing paste, size, or other adhesive or colour upon fabrics after such fabrics
have received a mechanical pasting, sizing, or colouring, as described.
Secondly. I claim the combination of appliances shown in Figures 2 and 3 of
the annexed Drawings, forming an apparatus for attachment to a pasting, sizing, or
colouring machine, for the purpose or purposes set forth.
In witness whereof, I, the said Joshua Blow, have hereunto set my hand
and seal, this Sixth day of August, in the year of our Lord One thousand
eight hundred and eighty.
