COMPLETE SPECIFICATION.
Improvements in the Manufacture of Enamelled Advertising Plates:
and other such articles.
I, JAMES ADAMS JORDAN of the firm of The Universal Enamelled Iron Company
Enamel Works Bilston in the County of Stafford Manufacturer do hereby declare
the nature of my said invention and in what manner the same is to be performed to
be particularly described & ascertained in and by the following statement:
My invention has for its object improvements in the manufacture of enamel
advertising plates & other such articles & refers more particularly to the mode of
clearing the superfluous dust from the stencils prior to finally fusing by which it is.
done more expeditiously & clearly than hithertofore and at the same time in such a
manner that there is no necessity for the operator to brush away the superfluous
dust from the stencil by hand which was objectionable by reason of the operator
inhaling the dust during the operation.
In order that my invention may be clearly understood & more easily carried into-
practice I have appended hereunto a double sized sheet of drawings upon which I
have fully illustrated the nature of my said improvements.
Figure 1 is a view shewing a plate B upon a table E with stencil A in position on.
plate ready for being cleared as shewn and hereafter described.
Figure 2 is a plan shewing a modification in the form of stencil.
Figure 3 is an elevation of Figure 2.
Figure 4 is a section on line 1-2.
I will proceed to describe my invention as applied to the manufacture of adver-
tising plates in which the surface is first coated and fused with one color & afterwards
coated with a second color & dried after which the stencil is placed upon the plate.
and that portion of the coating within the cutting on the stencil is brushed away
leaving the under coating exposed after which the plate is fused. Hitherto it has.
been necessary to effect the brushing away by the use of two stencils as in the case
of those letters having loose centres a³ Figure 1 one half a¹ of such letters have to
brushed away first & the remainder a² by means of a second stencil afterwards..
Now by my invention the whole of such letters may be cleared in one process with
one stencil although I do not confine myself to the use of one stencil as I may
find it convenient to use two stencils as before but in either case I use a sand
blast to clear away the coating from within the letters in the stencil; the sand H¹
which is directed from the nozzle H quickly cutting up the coating and leaving a
clear & sharp edge to the letters. In blasting with sand the loose centres of the
letters may be hung from the beam f³ which is mounted upon the pillars f¹ & which
supports the centre of the letters by the pendant f³ and thus the necessity for
two stencils is obviated. By my improved mode of manufacture the stencils last
much longer, the process is much quicker while it is much healthier for the operatives.
After the letters have been cut in the coating the plate is fused in the ordinary
manner.
Having now particularly described & ascertained the nature of the said improve-
ments & in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in the manufacture of enamelled advertising plates &
other such articles substantially as & for the purpose herein set forth and shewn
upon the accompanying drawings.
2nd. In improvements in the manufacture of enamelled advertising plates &.
other such articles the mode of & means for fixing the loose centres of the letters.

drawing.
