Improvements in Metallic Boxes for Containing Disinfecting or
other Powders.
We WILLIAM HENRY LLOYD of 71 and 73 Globe Road Mile End Tin Canister
Manufacturer and JOHN WYLDE of 179 Grove Lane Camberwell Chemist do hereby
declare the nature of this invention to be as follows:-
The object of the invention is in a simple and effective way to form a box for
containing disinfecting and other powders in such a manner that perforations formed
in its lid may readily be more or less opened-so as to give more or less access of air
to the interior of the box or more or less opening for the powder to be shaken through
the holes.
i
We form the upper part of the sides of a cylindrical box with a rim projecting
inwards from them. Through this inwardly projecting rim we form a number
of holes.
The lid we form with descending sides to fit over the exterior of the sides of the
top of the box and through the top of the lid we form a number of corresponding
holes so that by turning the lid the holes formed through it may be brought to
coincide with or to entirely close over the holes in the inwardly projecting rim.
The lid we preferably stamp out of one piece of sheet metal. The top surface we
dish inwards so that the portion through which the holes are formed may rest closely
down on to the surface of the inwardly projecting rim at the top of the box. The
centre of the top of the lid we also by preference dish somewhat inwards to
make it project downwards a short distance through the centre of the inwardly
projecting rim.

page_text: The inwardly projecting rim at the top of the box we form in one piece with a short
length of the sides of the box which is made in a separate piece from the remainder of
the box this short length we bulge outwards at the bottom into a V groove. The
upper edge of the sides of the lower part of the box we pass into this bulged portion
and turn it outwards so that it enters the groove and it is there retained by solder.
In the sides of the lid we form a T groove for a pin projecting from the side of the
box to enter. When the pin is at one end of the groove the perforations in the top of
the box coincide with the perforations in the lid and powder contained in the box
may be sprinkled out through them. When the pin is at the opposite end of the
groove the openings do not coincide and the box is closed.

Improvements in Metallic Boxes for Containing Disinfecting or
other Powders.
We, WILLIAM HENRY LLOYD, of 71 and 73 Globe Road, Mile End, Tin Canister
Manufacturer, and JOHN WYLDE, of 179 Grove Lane, Camberwell, Chemist, 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 :-
The object of the invention is in a simple and effective way to form a box for
containing disinfecting and other powders in such a manner that perforations formed
in its lid may readily be more or less opened-so as to give more or less access of air
to the interior of the box or more or less opening for the powder to be shaken through
the holes.
We form the upper part of the sides of a cylindrical box with a rim projecting
inwards from them. Through this inwardly projecting rim we form a number o
holes.
The lid we form with descending sides to fit over the exterior of the sides of the
top of the box and through the top of the lid we form a number of corresponding
holes so that by turning the lid the holes formed through it may be brought to
coincide with or to entirely close over the holes in the inwardly projecting rim.
The lid we preferably stamp out of one piece of sheet metal. The top surface we
dish inwards so that the portion through which the holes are formed may rest closely
down on to the surface of the inwardly projecting rim at the top of the box. The
centre of the top of the lid we also by preference dish somewhat inwards to
make it project downwards a short distance through the centre of the inwardly
projecting rim.
The inwardly projecting rim at the top of the box we form in one piece with a
short length of the sides of the box which is made in a separate piece from the remainder
of the box-this short length we bulge outwards at the bottom into a ✓ groove. The
upper edge of the sides of the lower part of the box we turn outwards and pass into
this bulged portion. In the sides of the lid we form a T groove for a pin projecting
from the side of the box to enter. When the pin is at one end of the groove the
perforations in the top of the box coincide with the perforations in the lid and powder
contained in the box may be sprinkled out through them. When the pin is at the
opposite end of the groove the openings do not coincide and the box is closed.
The drawing annexed shews various views of a metallic box formed as above
described.
Figure 1 is a side elevation, Figure 2 a vertical section and Figure 3 a plan.
Figure 4 is a plan with the lid removed.
The cylindrical portion of the lower part A of the box is made from tin plate in any
ordinary manner and its upper edge a is made to bulge outwards as shewn in section
at Figure 5. The upper part B of the box is made separately from a disc of tin plate. It

page_text: is first stamped to the form shewn at Figures 6 and 7 with an outward bulge b around
its lower edge and afterwards a circular hole is punched through its centre to bring
it to the form shewn at Figures 8 and 9-a pin 6 is also secured to it at the side as
shewn in that figure.
The two parts A and B are then put together in the manner shown at Figure 10 and
whilst they are supported upon a mandril the outward bulge 6 of the upper part B is
by means of what is known as a beading tool or in other suitable way closed over the
outward bulge a around the edge of the part A as shewn at Figure 2.
The lid C is also formed from a disc of tin plate. It is first stamped to the form
shown at Figures 11 and 12 and afterwards the holes c and the slot care stamped in
it to bring it to the form shewn at Figures 13 and 14.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :—
1. The construction of metallic boxes for containing disinfecting or other powders 1
substantially in the manner hereinbefore described and illustrated in the drawing
annexed.
2. The construction of the upper part of the body of the box from one piece of
metal with the perforated flange extending inwardly from the top of its sides whilst an
outwardly extending bulge is formed around its lower edge for the top edge of the
lower part of the box to be secured to it.
