Improvements in Ventilated Fly-proof Covers for Meat and other
Perishable Articles.
I, CHARLES EDWIN HAYWARD, of Auckland in the Colony of New Zealand,
Settler, 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 relates to improvements in covers especially adapted for meat and
other perishable articles, whereby such covers are thoroughly ventilated, and are
at the same time so constructed as to efficiently preserve the said meat or other
perishable articles from the action of flies or other insects.
According to my invention a rim or side piece is formed of wire gauze or
perforated plate, and to this rim the top or body of the cover is attached; at its
upper part the said body of the cover is so formed with holes or perforations as to
permit a current of air to pass from and through the gauze or perforated rim
beneath. When desired I further protect the upper perforations by wire gauze or
equivalent material.
My invention will be readily understood by the following description having
reference to the accompanying drawings, in which
Figure 1 shows in side elevation a ventilated cover constructed according to my
invention, and
Figure 2 a similar cover protected at its upper part.
Similar letters of reference indicate like parts in the several figures.
A is the rim or side piece shown as being of wire gauze, although finely
perforated plate metal may be employed, if so desired. B is the body of the cover
attached to the upper part of the rim; the body is formed of tin. or other suitable
material, generally being more or less dome shaped as shown, although the shape
may obviously be varied according to circumstances. Care the perforations in the
upper part of the body B.
In the cover shown at Figure 2. the perforations C are protected by a wire
gauze, or finely perforated rim A' mounted on the body B, the handle or knob for
lifting the cover being situated on the top of the secondary cover; by this means
flica or other insects are thoroughly prevented from depositing offensive or
deleterious matter through the small holes or spaces in the upper part of the body
while at the same time (in both the examples shown) efficient circulation of air is
obtained.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In ventilated fly-proof covers for meat and other perishable articles, the rim
or side piece of wire gauze or perforated plate to which is attached the body of the
cover all substantially as and for the purposes herein described and illustrated with
reference to the accompanying drawings.
2. In ventilated fly-proof covers for meat and other perishable articles, the wire
gauze or perforated rim A, in combination with the body B having upper
perforations C protected by rim A¹ forming a secondary cover all substantially as

page_text: described and illustrated especially with reference to Figure 2 of the accompanying
drawings.
