I, THOMAS AGNEW, junior, of Manchester, in the County of Lancaster,
Publisher, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN APPARATUS FOR COATING OR COVERING MOULDED OR OTHER SUR-
FACES WITH CERTAIN COMPOSITION OR MATERIAL," to be as follows:-
My Invention relates to improvements in apparatus which is designed
to apply the well known composition termed "whitening composition" to
moulded or other surfaces, and after such, composition has been applied and
become slightly "set," to effect or produce thereupon a hard smooth surface,
such as is required for subsequent gilding.
The improvements consist, first, in the novel employment and use of a
chamber or receptacle sliding from end to end of a framing, and containing
the composition beneath the surface to be coated (such surface, whether
moulded or plain, being face downwards); within this chamber a horizontal
brush roller, travelling band, or other medium rotates, and is so arranged as to
convey the whitening composition from the chamber and apply it to the afore-
said surface, the ends of such chamber through which the moulded surface
passes being so shaped or cut away as freely to admit the passage thereof and
yet sufficiently to confine the composition-within the chamber.
I wish to state that I prefer to operate upon two surfaces simultaneously,
for which purpose the two moulded surfaces are secured by clamps or other

page_text: simple means, one to each side of a bed or plate which is mounted on pivots
at each end in the framing of the machine, so that the bed may turn round
one moulding, always being face downward, and the other upward; the said
chamber is to be passed (and the brush driven) by rack and pinion or other
means from end to end of the moulding, which will cause the composition to
be applied to the then inverted surface in any required quantity, which is
adjusted and governed by the speed the brush is caused to rotate. Across
the top of this chamber and travelling therewith a "template" is secured,
which is a plate having an opening formed the reverse of the moulding, the
use of which otherwise applied being well known and commonly used for
defining the exact form of the coating of whitening composition, and also for
imparting a smooth polished surface thereto. Thus whilst the moulding
on the under side of the bed face downwards is being coated with composition
the one face upwards is being acted upon by the "template" which removes
the superfluous composition from the moulded surface, and smoothes the por-
tion remaining upon it, the superfluous composition falling again into the
chamber as the latter passes off the moulding. The upper moulding when
finished is removed and replaced by one requiring coating, the bed is turned
round and the lower one is brought uppermost, the chamber and template
is then passed back again, and so on.
A more simple arrangement may also be employed by separating the
chamber and template so that the moulded surface may first be coated by the
brush from the chamber below and then turned up and the template passed
over it as a second operation.
I would also remark that the bed may be hinged at one side, and by being
turned over the face of the moulding may be dipped into a chamber of com-
position, and then be submitted to the action of the travelling "template
or the composition may be applied with a brush by manual labor.
