I JAMES SINCLAIR of 20 Eglinton Street Monkwearmouth Sunderland county of
Durham Moulder do hereby declare the nature of this invention to be as follows:-
My improvements consist in arranging Moulding Boxes to work with hinges, also
means for raising lowering and stopping the top box, when required. The Hinges
are preferably my open lock Hinge. The means for lifting etcetera are sometimes
Handles with a form of Rack and Wedge for fixing in position or a Worm Gear and
Catches or their equivalents.

page_text: I, JAMES SINCLAIR, of 20 Eglinton Street, Monkwearmouth, Sunderland, 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:
The object of these Improvements is to save time, labour and space; to ensure good
lifts and to a certain extent to do away with Loam or other Guides also Clamps and
Weights. It will be found that these Improvements admit of a very general
application to existing Boxes. The principal Feature of these Improvements is the
application of Hinges to Moulding Boxes so as to better manipulate the work of
moulding coring &c. and to entirely separate the top and bottom parts if desired for
knocking out the parts after casting; together with a simple Form of Clamp, so that
when a Wedge is put in place, the Mould may be quite secure and ready for the
Metal. This Clamp greatly lessens the risk of bad Castings because usually several
Clamps are used causing the greater risk of parts of the Mould falling away. The
Box shewn with Worm Gear and Catches is one means or method for enabling the
Mould to be opened without assisstance and this method raises, stops & lowers the top
Box to any suitable position. Where preferred other well known arrangements of
mechanical Gear may be fitted. In the annexed Drawings Fig. 1 shows a front view of a
Moulding Box fitted up with the improvements. Fig. 2 shows an end elevation
clearly showing a style or form of open yet when in place Lock Hinge. Fig. 3. shows
an end elevation of a Box with Worm Gear and Catches arranged so that the Moulder
in some cases may dispense with additional help for lifting the top Box for coring &c.
A and A are top and bottom Hinges B and B top and bottom Boxes C the Rack or
Prop suitable Brackets, Da Wedge, E the Spindle or Axle which in the case of
Fig. 3 is prolonged to take the Worm Wheel to which it is keyed. H are the side
handles. Ordinarily the side Handles will be used the Rack or Prop C (Figs. 1 and 2)
let out, the Wedge D inserted at F so that the top box may be supported when turned
over. It will be seen that with the open lock Hinge the top box may be lifted quite
away from the bottom Box in almost any position or turned over in place without extra
trouble although I might use for Hinges close single and double eyes with loose pins.

page_text: 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. Applying Hinges to Moulding Boxes so as to better manipulate the working
of same.
2nd. Applying Worm Gear or other well known means in conjunction with Hinges
for raising the top Box.
3rdly. The application of what I term open lock Hinges.
4thly. The application of Rack and Wedge for safely and expeditiously clamping
top & bottom boxes together preferably in conjunction with lock Hinges.
Dated this 22nd day of May 1888.
