COMPLETE SPECIFICATION.
Improvements in Fasteners for the Lids or Covers of Butter-tubs
and the like.
I, WILLIAM WARD, Grocery and Provision Dealer, residing at Water Street,
Harbor Grace, Newfoundland, do hereby declare the nature of this invention and
in. what manner the same is to be performed, to be particularly described ani
ascertained in and by the following statement :--
This invention relates to an improvement in fasteners designed for use in
fastening the lids or covers of butter-tubs, etc., and the object is to provide a
fastener of this nature which, while securely holding the lid or cover in place when
so desired, may be operated to admit of the removal of the cover or lid without
extracting any of the nails primarily used in fastening the same. Obviously, many
advantages will be derived by the use of these fasteners among which is the facility
with which the contents of the tub may be displayed to intending purchaser, and
this in the butter trade is a serious desideratum.
My invention consists in the combination and arrangement of parts hereinafter
described and pointed out in the appended claims.
: j
In the accompanying drawings forming part of this specification :
Fig. 1 is a side elevation of a butter-tub having my invention applied thereto.
Fig. 2 is a similar view, the fastener in position to admit of the removal of the
cover; and
Fig. 3 is an enlarged view of the fastener removed.
A designates the butter-tub, B, the cover and C the loops or bands, all of any
ordinary or usual construction."
Within the inner loop or band of the cover, I arrange the fasteners D, preferably
three in number and these are formed out of any suitable metal, and I will now
proceed to describe their peculiar construction.
That part of the fasteners which is attached to the cover I will term the
member d and this member is provided at or near its lower end with a slit d' partly
formed in the member d and partly in the member d² adjacent to and forming part
of the fastener. Continuing, this member & terminates in a short member d³ at
right angles thereto and parallel with the member d sufficient space being left
between the two latter to admit of a nail E, which is driven into the tub and thus
prevents the lifting of the lid, all of which is clearly shown in Fig. 1 of the
drawings.
The lid or cover being thus fastened to the tub, it is only necessary to give a
slight movement of the fastener to the right, as shown in dotted lines in Fig. 1
which will enable the user to bend over the short member d³ until it comes
below the level of the head of the nail E when a movement to the left of the
fastener will admit of the ready removal of the lid or cover, it being only
necessary to reverse this operation to refasten the lid.
It will thus be seen that by use of my invention all necessity of removing
the nails is avoided, and that the covers or lids may be rapidly removed and as
and
speedily replaced, thus saving much time, annoyance and inconvenience;
when the cover or lid is permanently removed, the fasteners may be folded up
under the cover and out of the way.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is :-
1. A fastener for butter-tub covers and other like receptacles, comprising a
member swung from the cover and provided with a notch or slot and means for
fastening the same to the tub, substantially as shown and described.
2. A fastener for butter-tub covers and other like receptacles, comprising a
member pivoted to the cover, an adjacent member at right angles thereto, a notch
or slot and means for securing and releasing the fastener, substantially as shown
and described.
3. A fastener for butter-tub covers and other like receptacles, comprising a
member d pivoted to the inner face of the cover rim and having its lower end
provided with a notch or slot, the adjacent members d and d³ and means,
substantially such as described for securing and releasing the fastener, as set
forth.
4. A fastener for butter-tub covers and other like receptacles made of pliable
metal, comprising the member d pivoted to the cover and having its lower inner
end provided with a notch or slot d' at its junction with the projecting member d²
to receive a retaining stud E inserted in the tub between said member d and the
adjacent upright member ³, which member is adapted to be bent at a right angle
to release the fastener from engagement with the tub, whereby the cover may be
detached, substantially as shown and described.
