Machine for Painting Electric Casing and the like:
GEORGE HAWKINS CUTTING Electrical Engineer and GEORGE CUTTING late
Schoolmaster, both of 98, Uttoxeter New Road Derby in the County of Derby
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:-
According to this invention we provide a machine for the painting of Electric
Casing or strips or rods of wood or other material.
The strip to be painted is passed (according to the requirement of the case)
either under or above a revolving brush or brushes, these being placed in a con-
venient position for that purpose.
When two sides of a strip require to be painted at the same time, the said
strip is passed between one or, more pairs of revolving brushes. In each pair,
one brush is placed above the strip and one below.
When a third or fourth side of a strip is to be painted, brushes for this purpose
are provided, having their bristles set at right angles to the bristles of the afore-
said brushes but made to revolve in the same direction. The whole of the
revolving brushes are placed inside a box or case of metal or other material, so
that any splashing from the brushes is securely kept in a confined space.

In suitable positions in this case are placed the necessary bearings for the
revolving shafts, namely one on either side for each brush. These shafts are
prolonged outside the case so as to be fitted with gear wheels. These gear
wheels are so arranged as to give the requisite relative speeds to the different
brushes; and as all the shafts are geared together, when one of them is revolved
all the others are set in motion..
The strip to be painted is fed into the machine through a suitable opening
provided at one end of the " case," by means of a pair of rollers composed of
rubber or other material. These rollers are also geared to the shafts of the
brushes, and consequently are set in motion when the brushes are revolved or
vice versa.
The strip after being painted is brought away from the brushes through a
suitable opening provided in the end of the machine opposite to that by which
it entered.
The strip as it passes under or between the brushes is maintained in its proper
direction by adjustable guides attached to the case.
The paint required for the upper side of the work is fed on to it from a
receptacle at the top. By means of a tap in the feed pipe the supply of paint is
regulated according to the requirements of the work.
The superfluous paint removed by the top brush or brushes is made to fall
into a suitable well or dish at the bottom of the "case," and this paint is again
brought up by the bottom brush for the underside of the work.
In the drawings we have shown the mechanical arrangements whereby the
painting operation is performed, but we do not limit ourselves to the precise
design of outer case, or to the exact position of wheels as shown.

is fitted with a pipe which connects it with the interior of the " case S, and
also with a tap to control the supply. At the lower end of the pipe is a widened
outlet.

This machine offers many considerable advantages. For example, the great
rapidity and ease with which the work can be accomplished; the even-ness of
the paint laid on; the clean-ness of the operation, and consequent economy of
the liquid used.
Having now particularly described and ascertained the nature of our Invention,
and in what manner the same is to be performed, we declare that what we claim
is:
1. The use of a revolving brush or revolving brushes, enclosed in a box or
case for the application of paint or other liquid to Electric Casing or other strips
as shown and described.
"
2. The use of rollers geared to brushes mounted on shafts for drawing strips
to be painted into a machine for that purpose as shown and described.
3. The use of a dish or well, at the bottom of a case fitted with revolving
brushes, and fed from a reservoir above, for supplying paint to be carried by a
revolving brush to the underside of a strip to be painted.
