Apparatus for Securing the Chaplets Used in Supporting Cores
for Castings.
I GEORGE DYSON of 29 Bruce Street, New Wortley, Leeds, in the County of
York, Iron Moulder, do hereby declare the nature of my invention for APPURATUS
FOR SECURING THE CHAPLETS USED IN SUPPORTING CORES FOR CASTINGS to be
as follows:
The invention consists of one or more standards made to fix on to the moulding
box cross bars, the said standards to have a suitable recess or recesses for carrying, the
chaplet supporting bars, the said supporting bars to be adjustable by a screw passing
through the top of the said standards.

Apparatus for Securing the Chaplets Used in Supporting Cores
for Castings.
I, GEORGE DYSON, 29, Bruce Street, New Wortley, Leeds, Yorkshire, 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 :-
This invention has reference to means to be employed for preventing the core.
holding chaplets from rising when molten metal is poured into a mould.
As is well known these chaplets support the cores both underneath and above, which
chaplets unless weighted down rise or get displaced by the molten metal when it is
poured into the mould around the cores, whereby faulty castings are made.
The object of my invention is to provide a ready and positive means for preventing
the upward movement of the chaplets.
In order to do this I fix one or more pairs of steel jaws to the top cross bars of the
moulding box. Onto the top of these jaws I place a standard or box connected to
the jaws by a pin so as to swivel or be capable of moving around thereon. A bar is
then placed into an opening in each standard, which bar rests upon the top of the
chaplets and is held in position by a screw.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and for that purpose make reference to the accompanying sheet
of drawings which is perspective view of the top of a moulding box A, having my
improvements applied thereto. The moulding box is made in the ordinary manner
with the cross bars B, onto any of which I place steel jaws C, made secure thereto by
set screws a.
Onto the top of each jaw I place a box D which is secured to the jaws by a pin
so as to allow the box to oscillate opposite a corresponding box through two of which
I place a bar E.
These bars are placed onto the top of the chaplets b which project up above the
moulding sand, and such bars do not rest upon the bottoms of the openings in the
box, but they rest upon the top of the chaplets, and are held thereon by means of
screws and handles F.
By this means the moulten metal can not lift up the chaplets, consequently faulty
castings by their displacement are now avoided, and if the casting is being made
where a top and bottoin box is used, no weight to keep the box down is now
necessary.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
The means substantially as herein shewn and described for preventing the upward
movement of chaplets used in moulding.
