42 Roslea Drive, Glasgow, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the method and arrangement of mould for casting chains,
so as to cast the one link inside of the other.
The mould, which is made of iron or other suitable material, is constructed in four
pieces, which are fitted together, a space being left for the links already made to be
put into the mould, so that the link being cast will be inside the links already in the
mould, thus forming a chain.

An Improved Method and Arrangement of Mould for Casting
Chains.
We ANDREW MUIR, of 651 Gallowgate Street, Glasgow and PETER BURT of
Henrietta Street Glasgow in the County of Lanark, Scotland Engineers 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 relates to the method and arrangement of the mould for casting
chains so as to cast one link inside of the loop of one or two links already separately
formed.
The method consists of casting a link between and and connecting two links already
formed which said last two links may be formed either by casting or forging separately
as most convenient. Two or more series of three or more links may be again
connected by casting a link or links between and connecting said series, thus forming
a chain more expeditiously than by merely casting one link to and connecting on
one other.
The machine or mould for effecting the above is represented on the
accompanying 3 Sheets of Drawings on which Fig. 1 represents a plan; Fig. II a
transverse section on the line of Fig. 1, showing the face of one half of the chill or
jaws when open with link cast therein. Fig. 3 is a longitudinal sectional elevation the
"sectional part being on the centre line; Figs. 4 and 5 being Diagrams representing
the top halves of the mould and handles in different positions.
The Mould or chill which is made of iron or other suitable material which may be
lined or coated with any suitable material having good heat resisting properties, is
constructed in four pieces 1. 2. 3 and 4, which by means of the handles 5 can be
brought close together, curved spaces 6 being left which, when the two lower pieces 2
and 4 are close so as to bring their jaws together as indicated by diagram 5, leave
spaces into which one end of the already formed links 6" are fitted one end of the last
said links thus being inside and encircling the hollow space 7 which constitutes the
mould for the link to be cast in. Figs. 1. 2. and 3 represent the position of the
4 pieces and jaws of the mould or chill as nearly full open with a cast link 8 still in
position on one of the lower jaws with only one link connected to it.
The two lower half pieces 2 and 4 are fitted on to and slide along the sole plate 9, a
vertical spindle 10 being fitted in each. The spindles 10 are each rigidly fitted with
handles 5 and two cams 11 and 12, the lower cams 12 working inside and against the
transverse edges of square holes in sole plate said cams 12 and holes being indicated
on Fig. 1 in dotted lines. The top cams 11 works between two transverse flanges on
top pieces 1 and 3. The top pieces 1 and 3 are fitted to be carried by and slide along
the top of lower pieces 2 and slots 13 being formed in said top pieces through which
the spindle 10 projects.
One end of the links already formed being placed into the spaces 6 the handles are
drawn full round the cams thus acting on and closing the 4 jaws close together the
pins 15 fitting into holes 16 on opposite jaws, thus keeping said jaws from moving
transversely. Two gates 14 lead into the casting hollow space 7 constituting the

page_text: mould into which the molten metal is poured thus forming the link connecting the
already formed link or links held in the spaces 6.
We do not limit ourselves to the present mode of operating the machine or mould,
as said operation may be effected by Hydraulic, Steam, Pneumatic or Electric power,
whichever may be found most suitable and effective from time to time.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is.
1st. The method or process of forming or casting chains substantially as herein-
before described.
2nd. The arrangement, construction, and combination, of the Machine or mould for
forming a link between and connecting two already formed links substantially as set
forth and shown on the Drawings.
3rd. In a mould for casting chain links providing spaces inside the loop of casting
space to hold two already formed links therein while connecting link is being cast,
substantially as set forth and shown.
