I, CLEMENT SIMS of 98 St Martins Lane W.C. in the County of Middlesex
Cabinet Maker do hereby declare the nature of my invention for "IMPROVEMENTS
IN MECHANISM FOR OPENING AND CLOSING THE DOORS OR COVERS OF COAL BOXES
CABINETS AND OTHER RECEPTACLES" to be as follows:-
For this purpose the handle of a coal box cabinet or other receptacle is connected
to and combined with levers and links on each side attached to the door or cover
so that when the handle is moved in one direction the levers cause the door or
cover to be moved away from the opening to the coal box cabinet or other
receptacle to gain access thereto, and when the handle is moved back again the
door or cover is brought into position again to close the opening to the coal box
cabinet or other receptacle.

I, CLEMENT SIMS of 98 St Martins Lane, W.C. in the County of Middlesex
Cabinet Maker 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 :-
For this purpose the handle of a coal box cabinet or other receptacle is connected
to and combined with levers and links on each side attached to the door or cover
so that when the handle is moved in one direction the levers cause the door or
cover to be moved away from the opening to the coal box cabinet or other
receptacle to gain access thereto, and when the handle is moved back again the
door or cover is brought into position again to close the opening to the coal box
cabinet or other receptacle.
And in order that my invention may be clearly understood and readily carried
into practice I will proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section of a coal box having mechanism applied thereto
for opening and closing the same in accordance with my invention.
Figures 2 are details of the handle as I construct it when centred on the inside
of the coal box.
Figures 3 are details of the handle as I construct it when centred on the outside
of the coal box.
Referring to Figure 1-a is the body of the coal box into which a metal liner
containing the coals is placed. b is the lid or cover carried by arms c, pin jointed
to the sides of the box at c¹,-so far the description agrees with the coal box
described in the Specification of my Patent dated April 22nd 1885, No 4986, but
in place of moving the lid or cover by hand I now make use of the handle by
which the coal box is carried and this I do in the following manner.
To the handle d are attached two side bars or levers e turning on centres at e¹,
the lower ends of these bars or levers e are connected by links f with the arm c
carrying the lid or cover b, so that by moving the handle into the position shown
by dotted lines in Figure 1 the lid is fully raised and the contents of the coal box
can be readily removed.
Figures 2 shew the manner in which I construct the handle when it turns on
a centre inside the box.
Screwed to each side of the box is a metal fixing g having at its centre a circular
boss gl with a square hole therein, this boss projects inwards through a hole in the
side of the box and on to it is placed one of the side bars or levers e a square
plug having a flange h¹ and a screwed hole therein is then inserted into the hole
in the boss g¹ an ornamental boss g² is then placed over the fixing g on the outside
and the whole screwed up tightly by a screw i. thus on reference to Figures 1 and 2
it will be seen that the side bars or levers turn on the boss gl as a centre and
inside the box.

page_text: When the side bars or levers turn on a centre outside the box I arrange it as
shown by Figure 3. In this case the side bars or levers are constructed in two
parts . the part k, carries the circular boss e similar to g¹ of the previous
arrangement and the part the square plug 1 being similar to h in Figure 2.
The circular boss k¹, is inserted into a hole in the side of the box-the plug is
passed into the square hole in the boss, an ornamental boss m is placed upon the
outside of the part and the whole secured by a screw n. By these means the
two parts k. l. are firmly secured to each other and turn as one lever in the hole in
the side of the box. The part being then on the outside of the box.
This arrangement of mechanism can also be applied to a coal box or receptacle
having a curved door or cover.
From the previous description it will be evident that a competent workman will
readily apply my improved mechanism for opening and closing the doors or covers
of cabinets and other receptacles.
I would remark that I do not confine myself to the exact details of con-
struction herein before described so long as the main features of my invention
are retained,
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 I make
no claim to any of the parts separately but what I claim is:-
The improved arrangement combination and application of mechanism for
opening and closing the doors or covers of coal boxes cabinets and other recep-
tacles in which the movement of the handle d actuates the levers e. c. links f and
arms c, to raise or move the cover b to open the coal box or other receptacle and to
close the same substantially in the manner herein before described and represented
in the drawings hereto annexed.
