Improvements in Moveable Covers for Packages, Cases, Barrels,
and Boxes.
We, WILLIAM DE COURCY PRIDEAUX, 5 Fore Street, Wellington in the
County of Somerset, Ironmonger & Engineer JAMES CHADWELL CHAVE
5 Mantle Street Wellington in the County of Somerset, Agent and CHARLES
BAKER 8 High Street Wellington in the County of Somerset Grocer, 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 our invention is to protect the contents of casks bins tubs jars
cases or boxes or any other receptacles from dust or dirt when such casks bins
tubs jars cases or boxes hereinafter for the sake of brevity called a package are
being opened and having their contents used or dealt with. We carry our inven-
tion out in manner as hereinafter described.
Upon the open end of such package a casing or frame is fixed in manner as
hereinafter described and such casing or frame will be hereinafter styled the
frame. The frame may be made of sheet metal wood paper machie or any other
suitable material. To the frame a hinged sliding or pivotted door or flap is
attached this part of our invention will be hereinafter referred to as the flap or
cover. The frame is attached to the package by means of springs clips nails
rivets chains or any other suitable means.
The method of applying our invention is as follows.
When a package is opened the frame is put on the open end and attached to
the sides or suitable part of the package by means of clips nails screws or any
other suitable hereinafter described devices. When the contents of the package
are being used from the flap is opened and contents taken out and then the flaps
closed thus avoiding the dust or dirt falling into the package.
In order that our invention may be more readily understood we annex hereto
one sheet of drawings which are to be read herewith and taken as part of these
presents.
Figure 1 is a plan of the frame in which A is the cover which hinges at B ou
the frame C.
Figure 2 is another plan of a frame in which A is the cover sliding in groove
or channel D parts making up groove being attached to frame C.
Figure 3 is a further plan of a frame in which the cover A pivots or swings
at E upon the frame C.
Figure 4 is an elevation of the frame showing it in position upon a package and
also one method of fastening the frame to package by means of a spring which is
attached rigidly to the frame C at point K this however may be fixed in more
than one place if necessary and also so placed with reference to the package that
it can be placed wholly or partially round the package while it firmly grips it and
thus attaches the frame to the package. On reference to the drawing B is the
hinge F is the spring and H the package to which the frame C is attached.
Figure 5 shows an elevation of the frame C attached to the package H. A is
the cover D the groove or channel in which the cover slidės I is the knob for
pulling open or closing the cover, the plan of this arrangement is shown in
Figure 2.
Figure 6 is an elevation of the frame C attached to the package H. E is the
pin or pivot upon which the cover A turns I is the knob for actuating the cover,
the plan of this arrangement is shown in Fio 3

page_text: Figures 7, 8, & 9 show some methods of shaping the fasteners which are rigidly
attached to the frame C and have also to clip the package H in a firm manner
and are elevations of plans of springs shown in Figs. 10. 11. 12. of which Figure 8
is a sectional elevation.
Figure 10. shows a spring which takes in more than the half girth of the package.
J. J. J. shows the spring in its normal position. J'JJ' shows the spring when
it is clipping or holding the package for each spring suitable for it being larger
than the normal position or state of rest of the spring that is to say the spring
for a package must be when in its normal position smaller than the package to
which it is to be fitted so that the spring being extended or forced apart as
indicated by JJ J it tending to resume its normal position J. J. J. compresses
the package it is placed around.
Figure 11 is a modification of the method of spring clip shown in Figure 10
in this case the spring goes inside the package and may or may not extend more
than half the inside girth of the package but by preference it does so extend more
than half the inside girth of the package the action of the spring is as follows
LL. L is the normal position of the spring to fix it to package it is compressed
to position L L L and then placed inside the package it will tend to resume its
normal position and its resiliance in so doing will fix it firmly in package and
consequently the frame C to which spring L L I, is attached. The free ends of
the spring may be pointed or bent over to enter into the material of which the
package is composed or they may be looped or flattened out and pierced so as to
be fastened with nails screws rivets or other suitable devices.
Figure 12 is a further device for fixing M is a band of iron cord chain or any
other suitable material and N is a coiled or other spring which acts upon the ends
of the band M there may be one or more springs acting on the band M and in
this case the band M is made in two or more sections or pieces as may be
desirable.
Figure 13 illustrates a device for fastening the frame to the barrel O are ears
projecting over the side of the package H and are fastened to the package by
screws nails or any other well known devices or conversely these ears and screws
may be inside the package.
Some further modifications of the methods of fastening on frame are shown in
Figures 14, 15, 16, 17, 18, 19, 20, & 21.
Figure 14 shows one method of using a coiled spring which when at rest or not
fixed in package assumes the position shown at Q P is a clip that fits over the top
edge of the package. When ends of spring Q are drawn together and placed
inside package the spring strains against clip and thus fixes the frame in package
as clip P and spring Q are firmly attached to frame.
Figures 15, 18, and 19 show another arrangement of fastening spring Q which
is fixed in a more or less vertical direction relative to the cover and thus enters
the open end of the package in a more or less vertical direction to fix the frame
on the package the ends of spring Q are compressed together and then inserted in
the open end and allowed to expand the clip P being used to keep cover in
its place being placed either inside or outside the package as is deemed
desirable.
On reference to Figures 16 and 17 another method of applying the spring Qis
seen in this case no coiled spring is used but the spring is a plain straight or
curved one longer than the part of the package it fastens in and thus requiring to
get it into the package to be bent on itself and when this is done it is inserted
in the package and in tending to resume its original shape clips the package and
so fastens frame.
Figure 20 shows another way of shaping spring Q the extreme ends are bent in
and will thus when pointed enter the wood of the package.
Figure 21 shows the way the clip P is fastened to the frame and prevents the
tendency of the action of certain of the springs to displace the frame."

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The making of a moveable frame in the manner of and as hereinbefore
described and set forth.
2. The fastening same to packages in the manner as hereinbefore described and
set forth.
3. The combination of parts forming the frame as hereinbefore described and set
forth.
4. The combination of parts forming the frame and the methods of fastening
