PROVISIONAL SPECIFICATION
Improvements in the Manufacture of Sheet Metal Jelly, Pudding,
Blanc-mange and analogous Moulds.
I, HUGH MCCLELLAND of the Firm of McClelland Brothers, of Cambridge
Street, in the City of Birmingham, Merchant and Manufacturer, do hereby
declare the nature of this invention to be as follows
This invention relates to improvements in the manufacture of corrugated or
reeded sheet metal moulds in which puddings, jellies, blanc-manges and other
analogous confectioneries are moulded or shaped, and particularly to moulds made
of tinned iron or other coated metal although my invention is applicable to
uncoated sheet metal moulds, and has for its object principally prevention of the
bursting, stretching or buckling of both the body metal and coating metal, or the
separation of the said coating metal from the body metal during the process of
shaping and making.
The production of fluted, reeded or corrugated moulds from both plain and
coated metals by the ordinary process is fraught with difficulties in consequence of
the body metal being buckled or seared at parts, or the coated metal being broken
or separated from the body metal.
Now by my improved process, as hereinafter described, such defects are obviated
by distributing the area of the body metal blank over the superficial shape area to
be formed.
The process of production is as follows:-
A polished tinned-iron or other metal blank is taken and operated upon by a
pair of tools, which form the same into a shape alike unto a flattened and shallow-
corrugated mushroom head or umbrella, with or without a circular button shaped
or other sinking at the crown. The first-named blank then, may be operated upon
by a second pair of tools whereby its corrugations are deepened and its sides
gathered-in, thus giving to the said partially formed mould a figure resembling a
bell or an inverted cup with corrugated sides.
It is understood that the process of shaping is performed by he and she
tools corresponding to the inside and outside shape of the partially formed moulds
although if necessary this last named process may be dispensed with.
The said partially formed mould is then placed upon a boss or fluted he-die or
internal support of an outside shape corresponding to the inside shape to be given
to the mould; then by means of. a she or collar drawing-down die or bollow
corrugated tool, the desired shape is given to the mould by the drawing of the she
die over the he die with the said mould between them, and from which dies the
mould comes out with deep sides and nearly parallel crinkled flutings, and with the
body metal and coating metal upon the same left intact and unseared and
unbuckled. The edges of the mould may be subsequently cupped, turned-over or
trimmed in any desirable
way.
I wish it to be understood that the shapes of the moulds produced by my
improved process may be suitably varied without departing from the nature of my
invention.
Dated this 30th day of May 1895.

Blanc-mange and analogous Moulds.
1, HUGH MCCLELLAND of the Firm of McClelland Brothers, of Cambridge
Street, in the City of Birmingham, Merchant and Manufacturer, 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 improvements in the manufacture of corrugated, reeded
or fluted sheet metal moulds in which puddings, jellies, blanc-manges and other
analogous confectioneries are moulded or shaped, and particularly to moulds made
of tinned iron or other coated metal although my invention is applicable to
uncoated sheet metal moulds and has for its object principally the prevention of
the bursting, stretching, buckling or otherwise disturbing of both the body metal
and coating metal, or the separation of the said coating from the body metal
during the process of shaping and making.
The production of fluted, reeded or corrugated moulds from both plain and
coated metals by the ordinary process is fraught with difficulties in consequence of
the body metal being buckled or seared at parts, or the coating metal being broken
or separated from the body metal or disturbed.
Now by my improved process, as hereinafter described such defects are obviated
by distributing the area of the body metal blank over the superficial shape area to
be formed.
The process of production is as follows:-
:-
A polished tinned-iron or other metal blank is taken and operated upon by a pair
of tools, which form the same into a shape alike unto a flattened and shallow-
corrugated mushroom head or umbrella, with or without a circular button shaped
or other sinking at the crown
The said partially formed mould is then placed upon a boss or fluted he-die or
internal support of an outside shape corresponding to the inside shape to be
given to the mould; then by means of a she or collar drawing-down die or hollow
corrugated tool, the desired shape is given to the mould by the drawing of the she
die over the he die (or forcing the he-die through the she-die) with the said mould
between them, and from which dies the mould comes out with deep sides and nearly
parallel crinkled flutings, and with the body metal and coating metal upon the
same left intact and unseared and unbuckled. The edges of the mould may be
subsequently clipped, turned-over or trimmed in any desirable way.
I wish it to be understood that the shapes or patterns of the moulds produced
by my improved process may be suitably varied without departing from the nature
of my invention. Thus the said moulds may be elliptical, rectangular or fluted on
the twist, in which latter case one of the tools would take a slight rotatory
movement.
Figure 1 of the accompanying drawings represents in side elevation one form of
crinkled-sided or fluted jelly mould made according to my invention.
Figure 2 is a topside plan of the same.
Figure 3 is a side elevation of the top or he forcing through tool or mandril
tool, and Figure 4 is a plan of the same.
Figure 5 is a plan of the she-tool, which may, if necessary, be moved over the
prior named tool which is then held stationary.
Figure 6 is a horizontal section upon the dotted line a, Figure 5.
Figure 7 represents the polished and tinned sheet metal blank from which the
mould, Figures 1 and 2 is made

page_text: Figure 8 represents the said blank after being shallow stamped prior to the
gathering of the same into crinkles or folds.
Figure 9 is a cross section of Figure 8 upon the dotted line x².
In carrying out the production of a jelly mould, I take the blank Figure 7,
shallow stamp the same into the shape shown in Figure 8, and then drop the said
shallow stamping into a set above the open mouth of the lower die Figures 5 and 6,
when the upper-tool-then- descends-and-gathers or folds_the_metal between the
inside surface of the one die and the outside surface of the other. The blank
is pulled through the lower die and the desired figure given to it by the con-
tinued descent of the upper tool, whereby the body metal is shaped to the
desired figure and the coating metal upon the surface of the same is left intact or
undisturbed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is
First. In jelly and like moulds, fashioning the same by the gradual gathering-in
and pulling through process herein described and set forth.
Secondly. Fashioning jelly and like moulds from sheet metal by a pair of tools,
consisting of an open-ended die and a mandril tool substantially as herein described
and set forth.
Thirdly. The improvements in the manufacture of jelly, pudding and like moulds
from sheet metal substantially as herein described and set forth.
