PROVISIONAL SPECIFICATION.
A Plasterers' and Cement Workers' Self Mitreing Mould Runner
and Cutter, for Running Cornices and other Mouldings.
I, ELIZA MAIN of No. 2 Chapman Street, Loughborough in the County of
Leicester, Married Woman do hereby declare the nature of this invention to be
as follows:-
A zinc or metal mould cutter, fixed in a wood or metal frame, with side wings or
guides, the said cutter to work at an angle of 45 degrees (or any other angle) with
the moulding being run, so that when the tool arrives at the angle or end of the
moulding, the cutter is in a direct line with the mitre required, and by running
the tool on the opposite guide which is in a line or parallel with the next moulding
to be run, the mitre is formed. The mitres may be made to obtuse, acute or right
angles as required by altering the guides and angle of cutter. The cutter is fixed
in a frame and the guides are formed by a wood or metal plate or plates on the
bottom side and are stayed to the cutter frame by struts which form the handles for
working the tool. The frame is made so that the cutter may be secured by thumb
screws so as to allow for fixing of various patterns of mould cutters.

COMPLETE SPECIFICATION.
A Plasterers' and Cement Workers' Self Mitreing Mould Runner
and Cutter, for Running Cornices and other Mouldings.
I, ELIZA MAIN Married Woman 2 Chapman Street Loughborough Leicester-
shire 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 :-
A zinc, steel, or other metal mould cutter fixed in a wood or metal, or wood and
metal frame with side wings or guides. The said cutter to work at an angle of
45 degrees or at any special angle that may be required.
The tool when in use will form the mould required on a straight line in the same
manner as an ordinary plaster mould, but when it arrives at the angle or end of
moulding the cutter is in a direct line with the required mitre and by running the
tool on return side of angle it completes an exact mitre.
Fig. 1 is a perspective view of a mould for moulding a cornice. A is a metal
blade suitably shaped to form the required cornice and is attached by screws or any
other convenient method to the blade holder B which is secured to a base C and
a back support D. The front edges of the base, hereinafter called guiding faces
are preferably fitted with anti-friction rollers E and are arranged at such an angle
with the vertical plane of the blade that the latter will form a mitre at either an
internal or external angle. For a room with square corners the angle of each
guiding face with the blade is 45° F are struts or supports to the blade holder
and also form handles for the mould. In use the mould is kept in the required
path by the guiding piece G, which slides against the ceiling, and the guiding faces
which slide or roll against the wall, the underside of them being guided by a lath
temporarily fastened to the wall, as in using ordinary moulds. For rooms which
to

page_text: are not rectangular adjusting pieces H may be attached by screws or other suitable
means to the guiding faces the pieces H then form the guiding faces at the required
angle with the blade.
Fig. 2 is a perspective view of a mould for moulding architraves or panel
mouldings. In it A is the blade attached to the blade holder B. C are the guiding
faces (fixed at an angle of 45° to the blade for rectangular mouldings) which slide
against strips temporarily fixed to the wall or whatever the moulding is to be formed
upon. D are additional guides which guide the mould round arches or the like but
do not come into contact with the aforesaid strips which guide the mould for straight
work. These guides D may be attached to the guiding faces C by screws or any
· other suitable method.
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―
(1.) A mould for forming cornices, architraves and the like, in which the blade
is attached to a guide block, the guiding faces of which are set at such an angle to
the blade that the blade will form a mitre at either an internal or external angle:
substantially as described with reference to Fig. 1.
(2.) A mould constructed as described in the previous claim with additional
guiding surfaces: substantially as described with reference to Fig. 2.
