County of Warwick, for the Invention of "IMPROVEMENTS IN MAKING
REVOLVING DISHES AND REVOLVING BUTTER COOLERS, AND OTHER SIMILAR
ARTICLES."
Sealed the 17th April 1877, and dated the 19th October 1876.
PROVISIONAL SPECIFICATION left by the said George Green and Jaime
Mallol at the Office of the Commissioners of Patents on the 19th October
1876.

"IMPROVEMENTS IN MAKING REVOLVING DISHES AND REVOLVING BUTTER COOLERS,
AND OTHER SIMILAR ARTICLES."
In making revolving dishes, butter coolers, and such like articles as at present,
the bottom and cover of the revolving dish, butter cooler, or other article, is first
stamped out of a flat piece of metal, and the bottom is afterwards generally
encircled with wires forming a frame as it were to which the bottom of the article
is soldered, the whole being supported upon legs or fect. The covers are then
connected to the bottoms by what is known as a revolving joint, and a slot is cut
in the flange of the bottom of the article to allow the cover to revolve.
The object of this Invention is to make the supporting frame in a more expe-
ditious way, to apply the bottom in such a manner as that it can be quickly
removed from the frame for cleaning it, and to make an improved joint to those
hitherto used.
To make the frame a flat piece of metal of the proper size is cut either circular or
oval, according to the shape of the article to be produced, and from the centre of
this piece is cut another piece of the same size as the bowl of the bottom of the
article, so that the metal forming the flange of the bowl as at present made is left
in the metal from which the frame is to be made so as to form the frame and flange
of the bowl all in one piece. This piece of metal is now stamped in a die of the
proper shape so as to make a rim, and at a right angle a flange for the bowl of the
dish to fix in, and the edges are then what is known as "destroyed," either by

page_text: soldering a wire around them, or by lapping a wire in the manner described in
the Provisional Specification of our Invention for "Improvements in Mounting
Electro-plate Wares, such as Waiters, Side Dishes, Butters, Cake Baskets, and
other Articles of a similar Kind," bearing even date herewith, and it is then ready
for the dish or bowl.
The bottom is inade as at present, but with the necessary flange to rest on the
wider flange of the above mentioned frame, and the edge of the small flange of the
bowl is "destroyed" either by simply lapping it by soldering a wire, or by lapping
a wire by our above referred to improved process. The slot which allows of the
cover revolving is then cut in the flange of the rim instead of in the flange of
the bottom dish or bowl as at present.
The improved revolving joint is made of a short piece of tube threaded externally
at one end on which a cap fits, and made in halves lengthways, and this forms the
support of the pin soldered to the cover of the dish. The pin is made of the same
length as the tube and to fit the hole of the tube, and it has two flat heads leaving
between them exactly the space necessary for the tube. One of the flat heads is
soldered to the cover of the dish, and is made of the same diameter as the tube, the
other is made a little smaller in diameter than the tube and has a central projection,
against which the cap presses when screwed up, producing friction between the
other side of the head and the tube, so as to prevent the cover of the dish falling.
suddenly.
This joint may be applied to and used in connection with other revolving dishes
or articles.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said George Green and Jaime Mallol in the Great Seal Patent Office on the
19th April 1877.

"IMPROVEMENTS IN MAKING REVOLVING DISHES AND REVOLVING BUTTER COOLERS,
AND OTHER SIMILAR ARTICLES."
This Invention relates to the making of revolving dishes, butter coolers, and other
similar articles.
In making such articles as hitherto practised, the bottom, bowl, or dish, and the
frame, have been, stamped together from one piece of sheet metal, and afterwards
generally encircled with wires soldered thereto to strengthen the frame, which is
supported upon legs or feet. The cover which is also stamped from sheet metal is
then connected to the frame or dish by what is known as a revolving joint, and a
slot is cut in the flange of the dish to allow the cover to revolve.
The objects of this Invention are to make the frame in a more expeditious way
to apply the bottom, dish, or bowl, in such a manner that it can be quickly removed
for cleaning, and to make an improved revolving joint for allowing of the quick
removal of the cover.
The Invention is illustrated on the accompanying Drawings in Figures 1 to 4,
and 7 and 8, Sheet 1; and in Figures 5 and 6, Sheet 2.
To make the frame 1 we cut a flat piece of metal the required size and shape, and
from the centre thereof we cut another piece of the size the bowl or bottom is
required. The ring piece of metal which is left we then stamp in a die of the shape
the frame is required, and so as to form a broad flange 2. We then "destroy" the
edges 3, 4, of the flange 2, and of the frame 1, preferably by lapping wires 5 in the
manner described in the Specification of Letters Patent, No. 4037, bearing even
date herewith, and granted to us for our Invention of "Improvements in Mounting
Electro-plate Wares, such as Waiters, Side Dishes, Butters, Cake Baskets, and
other Articles of a similar Kind."
The frame and flange are represented in plan view in Figure 1, of which Figure 2

page_text: represents a cross section through a—b; Figure 3, through c―d; and Figure 4,
through e-f
In transverse section at any part the frame would then present the appearance
delinated in Figure 2; we then cut the slot 6 in the flange 2, and which allows of
the cover revolving, and which has hitherto been cut in the flange of the fixed bowl.
The legs or feet are then soldered to the rim 4 of the frame as usually, after which
the latter is ready for the loose dish, bottom, or bowl 7.
We form the bowl 7 (which is shown in plan view in Figure 5, and in transverse
section in Figure 6) by stamping the centre cut piece of metal above mentioned to
the shape required, and we make it with a narrow flange 8 to rest on, and be
supported by the wider flange 2 of the frame 1; and we also "destroy" the edge 9
of the flange 8 (see Figure 6), preferably by our above referred to improved
process. The loose bowl or dish is intended to be used with other makes of frames
than that herein-before described.
The improved revolving joint which is shown in elevation in Figure 7, and in
longitudinal section in Figure 8, we form of a short piece of tube 10 threaded
externally at one end on which a cap 11 fits, and made in halves lengthways. The.
tube 10 forms the support for a pin 12 which is as usually soldered to the cover 13
of the dish, see Figure 6. The pin 12 is made with two flat heads 14, 15, leaving
between them a length of pin equal to that of the tube 10 and fitting its interior.
The head 14 is soldered to the cover 13, and is made of the same diameter as the
tube 10, the head 15 is made a little smaller in diameter and has a central pro-
jection 16, against which the cap 11 presses when screwed up, producing friction
between the other side of the head and the tube 10 so as to prevent the cover 13
falling suddenly.
This improved joint may be applied to and used in connection with revolving
dishes or similar articles of the usual construction.
Having now described the nature and object of our said Invention together with
the manner in which the same is to be or may be performed or carried into practical
effect, we would remark in conclusion that we claim as our Invention,-
1. The improved method of forming the frame and bowl supporting flange.
2. The improved method of forming and applying the loose bowl.
And, 3. The improved revolving joint for revolving dishes, butter coolers, and
other similar articles, all substantially as above described and as illustrated on the
annexed Drawings.
In witness whereof, I, the said George Green, have hereunto set my hand
and seal, this Seventeenth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
GEORGE GREEN. (L.S.)
