Improved Means and Apparatus for Painting or otherwise Coating
Venetian and like Blind Laths or Slats, applicable also for
Painting Boards, Metal Strips, and the like other than Blind
Laths or Slats.
I, OLIVER WESTLAKE, of 147-9,. Great College Street, Camden Town, County
of Middlesex, Shop and Venetian Blind Manufacturer, do hereby declare the
nature of my said invention to be as follows:-
This invention has for object, painting or otherwise coating or staining say,
wood laths or slats by a combined dabbing or rolling and a brushing operation
for the coating and then for them to pass between a series of brushes for clearing
superfluous matter and for finally finishing previous to leaving the apparatus to
be dried.
To carry my invention into practice I prepare a trough of colour, size, stain or
other liquid body and dip a roller more or less into the same.
Just in front and slightly above the axial line I fit a brush to be in contact
and take its supply from the roller. which can be rotated by any means say, by a
treadle.
When a lath is to be pushed in between said brush and roller its end is dipped
and then forced up between the brush and roller and pushed inwardly, there being
sufficient colour lifted for coating the lath on both sides and edges.
The lath is then passed between one or more pairs of clearing and finishing
brushes and on issuing is placed upon or in a rack for drying.
The clearing and finishing brushes can be weighted or pressed on in any con-
venient manner the superfluous colour falling onto a shoot to return to the trough.
When sizing or varnishing is to be performed, I purpose using a stove or heat
for liquifying same.

I, OLIVER WESTLAKE, of 145, 147, and 149, Great College Street, Camden Town,
County of Middlesex, Shop and Venetian Blind Manufacturer, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:--
This invention has for object, painting varnishing or otherwise coating or
staining, say, wood laths or slats by a combined dabbing or rolling and a brushing
operation for the coating and then for them to pass between a series of brushes
for clearing superfluous matter and for finally finishing previous to leaving the
apparatus to be dried.
To carry my invention into practice, I prepare a trough of colour, size, stain, or
other liquid body, and dip a roller more or less into the same. Just in front and
slightly above the axial line I fit a brush to be in contact and take its supply
from the roller which can be rotated by any means, say, by a treadle. When a lath
is to be pushed in between said brush and roller its end is dipped and then forced
up between the brush and roller and pushed inwardly there being sufficient colour
lifted for coating the lath on both sides and edges. The lath is then passed
between one or more pairs of clearing and finishing brushes and on issuing is
placed upon or in a rack for drying.
The clearing and finishing brushes can be weighted or pressed on in any con-
venient manner, the superfluous colour falling on to a shoot to return to the trough.
When sizing or varnishing is to be performed I purpose using a stove or heat
for liquefying same.
My invention will be clearly understood by reference to the annexed drawings
in which Figure 1 is a sectional elevation of the machine or apparatus.
Figure 2 a front end view.
Figure 3 a back end view.
Figure 4 a plan.
A is the framework of the apparatus having a trough 13 for carrying the liquid
paint, stain, varnish, size, or other substance. C is a roller dipping into the
trough B and revolving in the liquid for conveying same to a brush D adjustably
fitted and held to the framework A by a set screw E.
F, G, are brushes having bars H, I, for engaging slots J in the framework A,
the bottom brushes F resting at the bottom of the slots J, the top brushes G
being capable of movement up and down in the slots due to the varying thickness
of the material being passed between them. K are weights resting on or forming
part of the brushes G to keep them to their work.
L is a shoot arranged underneath the brushes and fitted at an angle, so that
superfluous substance falling from the brushes F, G, may run back into the
trough B. M is a fast and loose pulley by which the roller C can be driven but
said roller may be driven by any other means, such as by a treadle action.
The brushes F, G, may be of different degrees of fineness and the weights K
may vary according to the pressure required to be placed upon the material being
passed through between the brushes, for instance, the first set of brushes through
which the material passes may be of a coarse nature and the weights heavy to
spread and remove the superfluous paint and the last set of brushes be of fine

page_text: texture and the weights of a light nature, so that the brushes only smooth the
paint or the like on the material being acted upon so that it leaves the apparatus
in a condition ready for drying and without streaks or imperfections.
In practice, the lath or other piece of material to be operated on has its end
first dipped in the trough B and is passed up between the brush D and roller C,
these smearing the paint on both sides of, say, the lath which is then pushed
through between the series of brushes for properly smoothening the paint on both
sides and edges, and its end after leaving the last set of brushes is caught hold
of by an attendant and the lath removed and placed to dry.
The number of sets of brushes may be varied according to the length of the
lath to be acted upon.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
-
1. The improved means and apparatus for painting or otherwise coating
venetian and like blind laths or slats, boards, metal strips, bars, rods, or the
like as described and substantially as illustrated on the annexed drawings.
2. In a machine or apparatus for painting or.otherwise coating strips or lengths
of material, the combination of a roller A, trough B, brush D, one or more sets
of brushes F, G, shoot L, all arranged substantially as set forth.
