IMPROVEMENTS IN CONSTRUCTING MOULDERS' CHAPLETS
Year: 1885

page_text: I, GEORGE WILSON of 48 Springfield Road Glasgow in the County of Lanark,
Moulder, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN CONSTRUCTING MOULDERS' CHAPLETS " to be as follows:-
This Invention which relates to improvements n constructing moulders' chaplets
has for its object to form such chaplets in or from one piece of metal instead of as
heretofore usually practised, of two or more pieces rivetted or otherwise secured
together.
Under the improved mode of construction an iron, steel or other metal bar or
plate of the desired width and length is taken and at distances apart corresponding
to the length of the base of the chaplet the plate or bar is cut or sheared in from
both of its edges towards the centre a solid part being left between the inner ends
of the cuts. Between the said cuts and the ends of the plate or bar other similar
cuts are made at each side the length between them and the cuts first mentioned
being equal to the length of the distance piece between the base and the other
resting or supporting part of the chaplet. The metal between the said cuts is
then by hand or by any suitable creasing and (or) forging apparatus bent preferably
into a channel form after which from the inner cuts the metal is bent at right
angles to the base thereby forming the distance pieces or studs and the metal
between the outer cuts and the ends of the plate or bar is similarly bent at right
angles to the distance pieces, that is to say, parallel to the base the chaplet being
thereby completed.
Under this mode of construction two or more chaplets may be cut or taken out
of one breadth of metal if desired and it is manifest that the shape or form to be
given to the chaplet may be considerably varied.
When greater strength in the distance pieces or studs is desired the metal bar or
plate from which the chaplet is to be formed may be rolled or made thicker at the
parts which will subsequently constitute the said distance pieces or studs.

page_text: I, GEORGE WILSON of 48 Springfield Road Glasgow in the County of Lanark,
Moulder 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 which relates to improvements in constructing moulders chaplets,
studs, or core supports has for its object to form such articles in or from one piece
of metal instead of as heretofore usually practised of two or more pieces rivetted
or otherwise secured together.
Under the improved mode of construction several examples of which are illus-
trated on the appended drawings, an iron, steel or other metal strip or plate of a
width equal to the desired breadth of the chaplet and of say one sixteenth of an
inch or other thickness according to the strength or rigidity required is submitted
to the action of a shearing or punching apparatus by which cuts are made inwards
from both edges towards the centre of the strip or plate a solid part being left
between the inner ends of the cuts. The cuts are in pairs that is to say the cut
made inwards from one edge of the plate or strip is exactly opposite that made
from the other edge and the number of such cuts at both sides of the plate is
regulated by the shape which it is desired the chaplet stud or core support shall
assume when finished.
In the example illustrated at figures 1, 2, 3, and 4 of the drawings figure 1
represents a length of plate equal to one entire chaplet Figure 2, is a side elevation,
figure 3, a horizontal section on the line x, x and figure 4 a perspective view of the
chaplet when finished. For this form the plate or strip is sheared or punched in
from both sides at a, b, c, and d, the pieces of metal between the cuts a, b and c, d,
being preferably removed or taken out of the plate although if desired they may be
left in. In proceeding with the manufacture the parts of the plate between bc,
are then by hand or by any suitable cressing or forging apparatus bent along the
dotted lines fat right or other angles to the parts g, so as to constitute a channel
form after which the plate is by like means bent or cressed on the lines h, i, j, and k,
into the form indicated at figure 2.
Instead of the distance pieces g, between the base 1, and the resting or supporting
surfaces m, being set inwards from the ends of the base 1, and supports m, as at
figures 2 and 3 they may as seen at figures 5 and 6 be at the extremities of the
base and of the supports in which case in preparing the plate the cuts b, c figure 1,
are not made, only two cuts a, d at distances apart equal to the length of the
distance piece being produced as at figure 7. In the example figures 1, 2, 3 and 4,
two supporting surfaces m are shown carried on the same base plate but as indicated
at figs. 2 and 3, three or other number of such surfaces may be so carried the metal
to constitute all such surfaces intermediate between the end ones and the distance
pieces connecting them to the base being punched out of the base itself.
Figures 8, 9, and 10 illustrate a construction of the chaplet slightly modified
from figs. 1, 2, 3 and 4 in which the base and supporting surface m, have the
same length.

page_text: Figures 4 and 4b illustrate another construction in which the part marked
figs. 4a and 4b constitutes the base the plate or strip after being cut inwards from
the edge being first folded or cressed along the lines f so as to cause the parts f¹, to
stand at right angles to the body of the plate. The part g is then folded towards
the base on the line hand from the base on the line i which results in the formation
indicated at j fig. 4b. The plate is then further folded on the lines k whereby.
the parts m are converted into distance pieces and the part n into the resting or
supporting surface.
Figures 4°, 4, and 4° illustrate another example substantially similar in which
the parts n constitute the resting or supporting surface the parts o the distance
pieces and the part p the base.
Figures 11 to 16 inclusive show a mode of constructing a pipe chaplet or stud or
"stangie" in accordance with my invention.
Figure 11 represents the plate from which the stud is punched out the stem n
being preferably tapered and in the process of manufacture bent into a V, semi-
circular, channel or other form as indicated at figures 14, 15 and 16. When it is
not desired that the stem n, should be under or approximately under the centre
of the rest or support o as shown but that it should extend downwards from the
hack edge of the said support as at figure 5, the cut r is dispensed with and the
stein carried out to the line s figure 11.
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
(1.) In the art or process of constructing moulders chaplets, studs or core
supports the improvement consisting in forming the article in or from one piece
of metal by shearing punching or cutting into both edges of the metal, the cuts
being at distances regulated by the shape to be given and by subsequently bending,
cressing or folding the metal at and from the cuts into the shape required
substantially as described.
(2.) As a new or improved article of manufacture, moulders chaplets, studs, or
core supports constructed in or from one piece of metal plate or strip cut in:o
from both edges and subsequently bent cressed or folded at and from the cuts into
the shape required substantially as described and illustrated by examples on the
appended drawings.
