Improvements in Machinery Employed in Producing Letters or
Designs upon Enamelled Surfaces.
I, CHARLES ARTHUR SMITH of Temple Row Birmingham in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manner in which I construct and arrange a machine for
brushing and cleaning off the powder from the stencil-plates used in the process of
enamelling metallic and other surfaces whereby I am enabled the more expeditiously
and efficiently to remove the powder from the surface of the plate, in all places not
covered by the stencil and at the same time to keep the stencil in its correct position
without disturbing it by the motion of the machine over and along its surface. I am also
enabled to more uniformly brush the surface of the exposed portion of the plate and
so give motion to the machine by a more constant and controllable system than is at
present adopted.
In carrying my invention into effect I construct a machine for removing the
powder from the exposed portion of the plate to be enamelled.
I form two side frames having bearings for carrying rollers or travelling wheels
running at each end; the two frames I connect together by means of stretcher bars
or distance pieces passing from one side to the other.
The running or travelling wheels I carry upon shafts which pass from side to side
and which are contained within the bearings formed upon or attached to each side
plate or frame.
The wheels or guide runners I prefer to run under the guide rails or girders so that
the weight of the machine is not carried upon the rails but presses down upon the
rollers within the frames beneath the wheel spindles.
From side to side of each frame 1 ass two or more spindles upon which I mount
circular brushes or cleaners and I arrange also in the same direction a series of rollers
covered with india rubber or other yielding composition for pressing down upon the
plate to be enamelled.
These covered rollers i carry within bearings upon each side plate having springs
for automatically pressing the rollers down upon the plate and for permitting them to.
rise and fall to accomodate the varying thicknesses or inequalities of the plate or
stencils.
The bearings for the brush spindles I adjust by means of screws for taking up the
wear and tear upon the surface of the brushes and for similar purposes.
The circular bushes I rotate by means of a main driving cotton wire or ordinarily
constructed driving rope which I cause to pass over the table of the enamelling
machine and which I drive and reverse by any well known ordinary gearing having
tightening pulleys and other usual accompaniments for controlling and reversing the
motion.
The driving rope I receive upon my machine by means of guide or bearing pulleys
carried upon one side of my frame which allow the rope to rest or pass over them
and then to pass under the pulleys carried upon the ends of the brush spindles; thus
giving motion to the brushes direct from the rope.
In some cases I arrange the machine so that it shall automatically reverse its
travelling motion and thus pass first over the plates in one direction, and then to
similarly pass back again over the same plates. Thus I carry into effect by one
method by placing a rod or striking bar along the line of the machine having an
adjustable loose collar, which I secure at any position to suit the particular require-
ments upon it against which some portion of my machine can strike and thus carry

page_text: over the belt forks or the levers actuating the cones or other driving arrangement
which I adopt. Although I do not limit myself to any particular method of reversing
the notion but employ any well known arrangement with similar advantage, providing
only that it shall be controlled by the machine itself.
I employ reducing gearing wheels for giving motion from one or both guiding or
bearing pulleys, to the travelling or rail wheels or runners and thus cause the machine
to travel along the rails as the brushes rotate.
I do not limit myself to any particular kind of brushes or rollers but employ any
well known form of bristle or other brush or any kind of yielding. india rubber, or
other suitable material upon my rollers with similar advantage.

COMPLETE SPECIFICATION.
Improvements in Machinery Employed in Producing Letters or
Designs upon Enamelled Surfaces.
I, CHARLES ARTHUR SMITH of 71 Temple Row Birmingham in the County of
Warwick, Engineer, 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 :-
My invention relates to the manner in which I construct and arrange a machine for
brushing and cleaning off the powder from the stencil plates used in the process of
enamelling metallic and other surfaces whereby I am enabled the more expeditiously
and efficiently to remove the powder from the surface of the plate in all places not
covered by the stencil and at the same time to keep the stencil in its correct position
without disturbing it by the inotion of the machine over and along its surface and the
stencil. I am also enabled to more uniformly brush the surface of the exposed portion
of the plate and to give motion to the machine by a more constant and controllable
system than is at present adopted.
In carrying my invention into effect I construct a machine for removing the powder
from the exposed portion of the plate to be enamelled.
I form two side frames having bearings for carrying rollers or travelling wheels
running at each end; the two frames I connect together by means of stretchers, bars
or distance pieces passing from one side to the other. The running or travelling
wheels I carry upon shafts which pass from side to side and which are contained
within the bearings formed upon or attached to each side plate or frame. The wheels
or guide runners I prefer to run under the guide rails or girders so that the weight of
the machine is not carried upon the rails but presses down upon the rollers within the
frames beneath the wheel spindles.
From side to side of each frame I pass two or more spindles upon which I mount
circular brushes or cleaners and I arrange also in the same direction a series of rollers
covered with india rubber or other yielding composition for pressing down upon the
plate to be enamelled.
These covered rollers. I carry within bearings upon, each side plate having springs
for automatically pressing the rollers down upon the plate and for permitting them to
rise and fall to accomodate the varying thicknesses or inequalities of the plate or
stencils.
The bearings for the brush spindles I adjust by means of screws for taking up the
wear and tear upon the surface of the brushes and for similar purposes. The circular
bushes I rotate by means of a main driving cotton cord, wire, or ordinarily con-
structed driving rope which I cause to pass over the table of the enamelling machine,
and which I drive and reverse by any well known ordinary gearing having
tightening pulleys and other usual accompaniments for controlling and reversing
the motion.

page_text: The driving rope I receive upon ay machine by means of guide or bearing pulleys
carried upon one side of my frame which allow the rope to rest or pass under the
pulleys carried upon the ends of the brash spindles; thus giving motion to the brushes
direct from the rope. In some cases 1 arrange the machine so that it shall auto-
matically reverse its travelling motion and thus pass first over the plates in one
direction, and then to similarly pass back again over the same plates. This I carry
into effect in one method by placing a rod or striking bar along the line of the machine
having an adjustable loose collar which I secure at any position to suit the particular
requirements upon it against which some portion of my machine can strike and thus
carry over the belt forks or the levers for actuating the cones or other driving
arrangements which I adopt. Although I do not limit myself to any particular
method of reversing the motion, but employ any well known arrangement with similar
advantage providing only that it shall be controlled by the machine itself.
I employ reducing gearing wheels. for giving motion from one or both guiding or
bearing pulleys, to the travelling or rail wheels or runners and thus cause the machine
to travel along the rail as the brushes rotate.
I do not limit myself to any particular kind of brushes or rollers but employ any
well known form of bristle or other brush or any kind of yielding india rubber or
other suitable material upon my rollers with similar advantage.
In the accompanying drawings Figure 1 is a side elevation of my improved cleaning
and brushing machine, and Figure 2 is a plan of the same.
Fig. 3 is an end elevation showing my improved machine in position beneath the
guide rails or guide beams, and Fig. 4 is a side elevation showing the guide rails and
the general enamelling table in position.
Referring to Fig. 1 and Fig. 2, A A' are the side frames upon which the rollers BB'
and brushes D D are mounted; suitable bearings being provided within each side
frame for the ends of the spindles.
The motion of the endless rope or cord E is imparted to the brushes or cleaners D D',
by means of the guiding rope pulleys F F¹ carried upon spindles at one side of my
machine and which pulleys direct the rope to the underside of the pulloys G G carried
upon the brush spindles g g'; the bearings of the roller spindles are preferably
mounted beneath springs 9 9' which permit of a slight rise or fall being given to the
rollers when revolving, and the spindles 99' are carried in bushes having set screws HH'
for adjusting the brushes to suit any particular thickness of plate or surface that may
be under the machine for enamelling.
The motion of the rope E being a fast one I reduce the speed down by suitable
gearing and worm wheel arrangement M, N, O, P, for causing the travelling
wheels K, K', to revolve at a suitable speed and thus move forward the machine upon
the guide rails or bearers J J.
I connect the side frames together by one or more stretcher bars S, and I mount the
rail wheels K K¹ upon cross shafts kk. Thus as the machine travels forward driven
by the endless cotton cord or wire rope E, the circular bushes D) D¹ revolve and
clean the stencil or plate while the rollers B B¹ press upon the plate or stencil and
keep the same in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The improvements in brushing and cleaning enamelling machines substantially
as and for the purposes hereinbefore described and illustrated in the accompanying
drawings.
2. In a brushing or cleaning machine employed in the process of producing
enamelled surfaces, the arrangement of circular revolving brushes such as D D
with circular pressing or holding down rollers such as B B₁ as and for the purposes.
set forth, and illustrated in the accompanying drawings.
3. In a brushing or cleaning machine for enamelling processes, the arrangement of
a cotton cord or wire, driving endless rope such as E for operating the said machine

page_text: in the manner hereinbefore described and as illustrated in the accompanying
drawings.
4. In a brushing or cleaning machine for enamelling processes, the arrangement of
guide rollers such as K K' for running underneath instead of upon the top of the
guide rails or beams J J' substantially as, and for the purposes hereinbefore described:
and illustrated in the accompanying drawings.
