PROVISIONAL SPECIFICATION.
New or Improved Apparatus for Stirring Enamel Mixtures Used in
the Manufacture of Enamelled Metallic Name Plates. Wall Plates,
and other like Metallic Plates, and other Enamelled Metallic
Articles.
I BENJAMIN BAUGH of The Imperial Enamel Works, Watery Lane
Birmingham in the County of Warwick, Manufacturer do hereby declare the
nature of this invention to be as follows:-
The enamel mixtures used in the manufacture of enamelled metallic name
plates wall plates and other like metallic plates, and other enamelled articles
set quickly that is, the suspended particles fall through the liquid to the
bottom of the bowl containing the enamel mixture and hence the quantity of
suspended enamel rapidly diminishes and the workman has from time to time to stir
the enamel mixture to preserve its uniform character.
My invention has for its object to obviate the inconveniences attending the
ordinary method of preserving the uniform character of the enamel mixture and
my said invention consists of the construction and combination of the parts
hereinafter described of apparatus for automatically stirring the enamel mixtures
in the bowls containing them, without interfering with the free access of the
workman to the bowls containing the said enamel mixtures as bereinafter
described.
The essential parts of the apparatus constituting my invention consist of a
rotating bowl, containing the enamel mixture, in combination with fixed brushes or
stirrers for stirring the said enamel mixture. The rotating bowl is supported ou a
fixed vertical axis on its underside the said axis and bowl being driven from a
horizontal shaft by bevil gearing. The said rotating bowl works closely in
a circular opening in the work bench and the fixed brushes or stirrers, within the
bowl, are attached to carriers or stems of different lengths and the latter are fixed
to a horizontal bar crossing the bowl as a diameter, the said cross bar being
supported upon the work-bench and above the bowl by short uprights on opposite
sides of the bowl. The brushes or stirrers are situated in the same line but are
slightly inclined to the middle cross bar carrying them. The carriers or stems of
the brushes are of such varying lengths that the acting parts of the said brushes
touch or nearly touch the bottom of the bowl. By the rotation of the bowl in
conjunction with the fixed brushes or stirrers, the enamel mixture in the bowl is
thoroughly stirred and its composition maintained uniform. By the position of
the fixed brushes or stirrers with respect to the rotating bowl the halves of the
bowl, on opposite sides of the fixed brushes or stirrers, are free from obstruction
so that the workman can use the half of the bowl nearest to him either to dip the
article being enamelled into the enamel mixture or to dip in his brush and take up
the enamel mixture according as he is operating with body enamel or with coloured
enamel.
A series of rotating bowls and fixed brushes or stirrers may be arranged at
uniform distances apart along the same work-bench; and the series of rotating
bowls may be driven from the same horizontal shaft.

the Manufacture of Enamelled Metallic Name Plates, Wall Plates,
and other like Metallic Plates, and other Enamelled Metallic
Articles.
I BENJAMIN BAUGH, of The Imperial Enamel Works, Watery Lane
Birmingham in the County of Warwick, Manufacturer do hereby declare the
nature of my invention and in what manner the same is to be performed to be
particularly described. and ascertained in and by the following statement :-
The enamel mixtures used in the manufacture of enamelled metallic name plates,
wall plates and other like metallic plates, and other enamelled articles set quickly;
that is, the suspended particles fall through the liquid to the bottom of the bowl
containing the enamel mixture and hence the quantity of suspended enamel rapidly
diminishes and the workman has from time to time to stir the enamel.mixture to
preserve its uniform character.
My invention has for its object to obviate the inconvenierces attending the
ordinary method of preserving the uniform character of the enamel mixture;
and my said invention consists of the construction and combination of parts
hereinafter described of apparatus for automatically stirring the enamel mixtures
in the bowls containing them, without interfering with the free access of
the workmen to the bowls containing the said enamel mixtures as hereinafter
described.
The essential parts of the apparatus constituting my invention consist of a
rotating bowl, containing the enamel mixture, in combination with fixed brushes
or stirrers for stirring the said enamel mixture. The rotating bowl is supported
on a vertical axis fixed on its underside, the said axis and bowl being driven from
a horizontal shaft by bevil gearing. The said rotating bowl works closely in a
circular opening in the work-bench and the fixed brushes or stirrers, within the
bowl are attached to carriers or stems of different lengths and the latter are fixed
to a horizontal bar crossing the bowl as a diameter, the said cross bar being
supported upon the work-bench and above the bowl by short uprights on opposite
sides of the bowl. The brushes or stirrers are situated in the same line but are
slightly inclined to the middle cross bar carrying them. The carriers or stems of
the brushes are of such varying lengths that the acting parts of the said brushes
touch or nearly touch the bottom of the bowl. By the rotation of the bowl in
conjunction with the fixed brushes or stirrers, the-enamel mixture in the bowl is
thoroughly stirred and its composition maintained uniform. By the position of the
fixed brushes or stirrers with respect to the rotating bowl; the halves of the bowl,
on opposite sides of the fixed brushes or stirrers, are free from obstruction so that
the workman can use the half of the bowl nearest to him either to dip the article
being enamelled into the enamel mixture or to dip in his brush and take up the
enamel mixture according as he is operating with body enamel or with enamel
colours.
Figure 1 of the accompanying drawing represents in vertical section and Figure 2
in plan, apparatus for stirring enamel mixtures constructed according to my
invention, the said apparatus being provided with a series of stationary brushes
or stirrers ;
Figures 3 and 4 represent sections of the apparatus, taken in planes at right
angles to one another, in which a single long stationary brush or stirrer is used and
Figure 5 represents a plan of the same.

page_text: The same letters of reference indicate the same parts in the several figures of
the drawing.
a is the rotating basin or bowl containing the enamel mixture to be stirred, the
said basin or bowl being supported on the vertical driving axis b fixed to the
underside of it. The said basin works closely in a circular opening c in the work-
bench d. The vertical axis carrying the bowl is supported in a bearing on the
bracket e and the said axis is driven from the horizontal shaft through the bevil
toothed wheels g and h. The bevil wheel on the driving shaft ƒ is thrown into
and out of gear with the bevil wheel g on the vertical axis b so as to rotate the
basin a or bring it to rest, by means of the sliding clutch i working on the shaft f,
the said clutch i being operated by the hand lever k turning on the centre ³. The
handle end of the lever k projects through a slot in the table d so as to be readily
accessible to the workman for rotating and arresting the basin or bowl.
The stirrers represented in Figures 1 and 2 consist of a series of brushes m
having stems of different lengths, the said brushes being supported by and fixed to
the adjustable horizontal bar n secured to the workbench d. The brush supporting
bar n is situated a little above and crosses the basin a radially and the brushes m
are slightly inclined to the said bar n. The position of the brush supporting
bar n is adjusted by sliding it in the looped bracket p on the table and fixing it by
the binding screw q, and the vertical and horizontal position of the brushes, is
adjusted, so that their acting parts touch or nearly touch the bottom of the basin
by the screw nuts at r, r and the longitudinal slot in the bar n in which slot the
stems of the brushes are situated. By means of the adjustments represented,
the horizontal and vertical positions of the brushes can be effected with great
nicety.
Instead of using a series of nearly vertical brushes in the rotating bowl or
basin, a long single brush the stem or body of which is curved to follow the
curvature of the inside of the basin may be employed as represented in Figures 3, 4
and 5. In this modification the end of the curved stem or body of the brush sis
supported in the slotted bracket t and the said brush is adjusted vertically in the
said bracket by the screw nuts u, u. The horizontal adjustment of the brush is
effected by moving the slotted bracket t more or less in the loop a and fixing it by
the binding screw y..
In place of flexible stirrers in the form of brushes, rigid stirrers may be used
and the brushes or stirrers may completely cross the basin in the direction of a
diameter instead of partly crossing it as represented in the drawing.
By the rotation of the bowl containing the enamel mixture, in conjunction with
the stationary stirrers crossing or partly crossing the bowl, the said enamel mixture
is thoroughly stirred and its composition maintained uniform It will be seen that
the position of the stationary brush or brushes or stirrers with respect to the
rotating bowl is such that it or they offer no obstruction to the workman gaining
access to the bowl for the purposes hereinbefore explained.
A series of rotating bowls and stationary brushes or stirrers of the kinds or
substantially of the kinds described and represented may be arranged at uniform
distances apart along the same work bench; and the series of rotating bowls may
be driven from the same horizontal shaft.
Having now particularly described and ascertained the nature of my inven-
tion and the manner of performing the same I declare that I claim as my
invention;-
The new or improved apparatus for stirring enamel mixtures used in the
manufacture of enamelled metallic name plates, wall plates and other like metallic
plates and other enamelled metallic articles herein before described and illustrated
in the accompanying drawing; that is to say, apparatus for the purpose described
consisting essentially of a rotating bowl or basin containing the enamel mixture,
in combination with a stationary brush or brushes or other stirrers crossing or

page_text: partly crossing the rotating bowl or basin and made capable of adjustment, the
several parts being combined or arranged and worked substantially as described
and illustrated.
