Improvements in the Manufacture and Construction of Handles for
Dish-covers and of other Metal Handles of a like Character or
Description.
I, ALFRED NIND HOPKINS, of the firm of J. H. Hopkins and Sons, of Granville
Works, Birmingham in the County of Warwick, tinplate workers, and Japanners,
do hereby declare the nature of this invention to be as follows :-
This invention has for its object to cheapen the manufacture and improve the con-
struction of the handles named in the title.
According to this invention, the bows and bosses or feet are formed of tinplate or
other sheet metal, and tho screws by which the handles are to be fixed in place are
secured within the bosses by soldering or otherwise. The halves of the bow which lie
on opposite sides of the longitudinal axis are formed separately, by pressing or
stamping in suitable tools, and are then joined together by soldering or in other
convenient manner. The bosses or feet are "raised" in suitable tools and have each
a hole formed through the back or outer plate thereof to receive an end of the bow.
The half-bows are formed with reduced ends which are passed through the holes in the
bosses when the bow is made up, and shoulders formed by reducing the ends bed
against the backs or outer faces of the bosses. The reduced ends of the bows which
project into the hollows of the bosses are soldered or otherwise fixed within such
hollows.
A convenient method of fixing the half-bows together is to first form them with
outward flanges, then to turn up such flanges parallel, or approximately so, with one
another, and so that the flanges of one half-bow may be inserted tightly between the
flanges of the other, and then, after putting together the halves in this manner,
squeezing the outer flanges towards one another by which means the two halves are
securely fixed together. The bow thus formed may have the halves still further
secured to one another, when of tin-plate, by re-dipping in molten tin; and this operation
has also the effect of brightening them.
The halves of the bow may, however, be fixed by simply lapping the edges of the
one over the edges of the other and soldering them together; or the edges may be
formed each with a slightly turned out rim, and a thin open-jointed tube or channelled
strip be placed over each abutting pair of such rims and be soldered thereto to fix the
halves together.
Instead of forming the bows and bosses separately from one another as above
described, each half-bow may be formed in one piece of tinplate or other sheet metal
with a half boss at each end, by pressing or stamping in suitable tools, and the half-bows
and hosses thus formed may be put together in pairs and fixed in any manner above
described, with reference to the half-bows, to form the complete handles (excepting
for the screws which are afterwards secured thereto by soldering or in other
convenient manner) in lieu of fixing the bosses separately as above described.
Handles made in the manner above described are much cheaper and, when made of
tinplate and re-dipped, have a more brilliant appearance, than when cast solid as in the
usual method of manufacture and construction.

Improvements in the Manufacture and Construction of Handles for
Dish-covers and of other Metal Handles of a like Character or
Description.
I, ALFRED NIND HOPKINS, of the firm of J. H. Hopkins and Sons, of Granville
Works, Birmingham in the County of Warwick, tinplate workers and japanners,
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 for its object to cheapen the manufacture and improve the con-
struction of the handles named in the title.
According to this invention, the bows and preferably also the bosses or feet are
formed of tinplate or other sheet metal, and the screws by which the handles are to be
fixed in place are secured within the bosses by soldering or otherwise. The halves of
the bow which lie on opposite sides of the longitudinal axis are formed separately from
one another, by pressing or stamping in suitable tools, and are then joined together in
any convenient manner. The bosses or feet, when of sheet metal as is preferred, are
"raised" in suitable tools and are joined to the bows by soldering or in other convenient
manner.
A convenient, and as I at present find the preferable, method of carrying out this
invention in practice is shewn by the drawings herewith, of which figure 1 is a plan
of a flat annular blank from which two half bows for distinct handles are to be formed.
Figure 2 is a plan view of the same pressed or stamped into the trough shape shewn
in section by figure 3, that is with the upper sides a a of the trough shouldered out
from the lower portion and also inclining outwardly as shewn. For each pair of
complete handles required, one blank such as shewn by figure 1 is pressed or stamped
into a trough shape of the section shewn by figure 3, and one such blank is pressed or
stamped into a trough shape of the section shewn by figure 4, with the upper sides bb
also shouldered out from the lower portion and inclining outwardly, but of such a
width across at the top as will permit of its being turned over edge downwards and
placed with the sides bb between the sides a a of the other trough, and resting against
the shoulders of such latter trough, as shewn by figure 5. The two circular troughs
thus formed to fit the one within the other are firmly fixed together, whilst placed in
the relative position with one another shewn by figure 5, by spinning turning or
closing the sides a a of the one trough tightly against the sides bb of the other trough,
as shewn by figure 6, the inclination of the sides giving a very firm hold. The hollow
ring thus formed may, if desired, when made of tinplate, be dipped into molten tin to
still further secure and close up the joint, but this is not at all essential. Such dipping
has also the effect of brightening the ring. The ring is sawn across at opposite sides,
as indicated at c c figure 7, to form it into two bows.
The bosses or feet are pressed or stamped from metal blanks. One of such bosses is
shewn in vertical section by figure 8, and in plan by figure 9. Each boss is formed
with a short internal downward socket d which, preferably, tapers smaller in diameter
downwards and is of such dimensions that the end of a bow will enter from the upper
side but cannot be pushed through the socket, the bottom of which is preferably punched
out to leave a clear opening therethrough.
The end of a bow is joined to a boss by first inserting it into the socket d of the boss
and then soldering.
The screws are formed with flat heads e, as shewn by figure 10 which is a detached
view of one of the screws, and are fixed in place by means of dished plates f one of
which is shewn in section by figure 11 and in plan by figure 12. Each of these plates
has a hole through its centre through which the screw passes, and to fix a screw within
a boss after the bow has been fixed thereto the plate is passed up over the lower end
of the screw and against the underside of the head and is then soldered around its 5
periphery to the inside of the boss. The plates fare dished to such degree that when

page_text: in place within the bosses they press the heads of the screws against the lower ends of
the sockets d. It is preferred to run some of the solder into or around the crevice
formed between the screw and the edge of the hole in the plate through which it
passes.
Figure 13 shews, in vertical section, a complete handle constructed in the manner
above-described.
The balves to form a hollow ring as above described may be formed with plain
vertical sides, shouldered out from the lower portions or not, and be fixed together by
simply lapping the edges of one over the edges of the other and soldering the joint;
or the edges may be formed each with a slightly turned out rim g (see figure 14 which
is a corresponding view to that shewn by figure 6) and a thin open-jointed tube or
channelled strip be placed over each abutting pair of such rims and be soldered
thereto to fix the halves together. At the right-hand side of the section the rims
are shown without the channelled strip thereover, and such strip is shewn a short
distance back therefrom.

Parts which are soldered together cannot of course be dipped into molten metal.
It is not essential in making the bows to first.make complete rings and saw them in
halves as described, as each half bow may be pressed or stamped direct from a suitable
blank, that is frou a blank of which a pair would be formed by cutting the blank
shewn by figure 1 into halves.
Instead of forming the bows and bosses separately from one another as above
described, each half bow may be formed in one piece of tinplate or other sheet metal
with a half boss at each end, by pressing or stamping in suitable tools, as will be
readily understood, and the half bows and bosses thus formed may be put together in
pairs and fixed in the manner above described with reference to the bows, to form the
complete handles (excepting for the screws which are afterwards secured thereto by
soldering or in other convenient manner) in lieu of fixing the bosses separately as above
described.
Handles made in the manner above described are much cheaper in manufacture and,
when made of tinplate and the bows, or the bows and bosses complete as the case
may be, dipped into molten tin, have a more brilliant appearance than when cast solid
as in the usual method of manufacture and construction.
This invention has been described specially with reference to the manufacture and
construction of bow handles for dish covers; it will be obvious however that it is
applicable in the manufacture and construction of other metal handles also of a like
character or description. In the case of ring handles the rings are formed according
to this invention in the manner of the hollow rings above described.
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 :-
1. The improvements in the manufacture and construction of handles for dish
covers and of other metal handles of a like character or description, substantially as
described.
2. The improvements in the manufacture of bow handles for dish covers and of other
metal bow handles of a like character or description, which consist in pressing
or stamping the parts to form the bows and bosses from sheet metal blanks and
then joining the separate parts together, substantially as described.
3. In the manufacture of bow handles for dish covers, and of other metal bow
handles of a like character or description, forming tubular bows of sheet metal of halves
joined longitudinally, substantially as described.
4. In the manufacture of ring handles, forming the rings of a tubular shape of
annular channelled pieces of sheet metal joined together, substantially as described.
5. In the manufacture of handles for dish covers, and of other metal handles of a
like character or description, pressing or stamping channel rings from annular sheet
metal blanks, substantially as described for the purpose set forth.

page_text: 6. In the manufacture of handles for dish covers, and of other metal handles of a
like character or description, pressing or stamping pairs of channel rings from annular
sheet metal blanks to such shapes that the edges of the one ring will enter within the
edges of the other and that the subsequent spinning turning or closing in of the outer
edges against the inner will cause the pair of channel rings to be firmly fixed together
and form a hollow ring, substantially as described for the purpose set forth.
7. Handles for dish covers, and other metal handles of a like character or
description, having bows or rings of tubular section formed from sheet metal,
substantially as described.
8. Handles for dish covers, and other metal handles of a like character or
description, constructed in the manner substantially as shewn by the drawings
herewith.
