PROVISIONAL SPECIFICATION.
An Improved Top and Cover for Milk Churns, Cans, and the like.
I, EDWARD MASKREY Tin Plate Worker 3 Agard Street Derby do hereby
declare the nature of this invention to be as follows:-
I construct a top for milk churns and the like, of any suitable metal or substance
having in the inner side thereof, two projections of any convenient size placed
generally opposite each other and placed any convenient distance above the flange
or bed upon which the lid or cover rests.
I construct the lid or cover in any suitable metal or substance, in any similar
shape to those generally used or in any shape, but, the outer edges of which are
bevelled to and fit down on the flange constructed on the top aforementioned.
In the outer edge of the cover 1 make a slot slightly larger than the projections in
the sides of churn top aforementioned.
To fix the cover on the top it is necessary to place one side of cover on the flange
under one of the projections in side of top, bringing the slot in cover opposite the
other projection in side of top when the cover is free to fall into a resting position
on the bed or flange.
A slight turn is then sufficient to fix the cover securely to the top.
As will readily be seen this invention does away with the necessity of having
hinges, hooks, staples, chains, springs and the like in fixing cover to top and
greatly facilitates perfect and easy cleaning of the churn also: and rapid and simple
fixing or removing of cover.
Dated this Thirteenth day of February 1894.
An Improved Top and Cover for Milk Churns, Cans, and the like.
EDWARD MASKREY Tin Plate Worker Agard Street Derby, 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 consists of an improvement in the upper part of a churn or can or
such like vessel used for general holding purposes such as holding and conveying
milk or other liquids or for any general holding purpose, and the invention is
intended to do away with hooks, chains, bolts, hinges, springs and all loose
fastenings, which are more or less generally in use for fastening the lids or covers
to the tops or upper parts of milk churns and the like, this invention is also
calculated to minimise labour and to ensure perfect cleanliness by doing away with
the loose parts aforementioned, and in addition to the foregoing great saving of time
in fixing or removing the cover or lid from the top or body of the churn, vessel
AT 00n

page_text: This invention deals with and consists of two parts.
Firstly the upper part or top of a can, milk churn or vessel of like nature which
I call hereafter the "top" in this Specification.
Secondly the covering part or lid of a milk churn, can or vessel of like nature,
which I call hereafter the " cover in this Specification.
"
The invention consists in the manner and method in which the said cover
is attached to and detached from the said top and the means which I employ for
that purpose.
I make in any suitable metal, earthenware or substance the top B Fig. 2 the
same being a dished rim or hoop of any desirable depth generally about four
inches the lower edge of which may be arrauged to fit on to the body of a churn,
vessel or can by any well known means or the top may even be an extension of the
body of a churn, vessel'or can; now in the inner side of the said top I make a
flange or bed-which I call hereafter the "bed "-which may be set at any
angle or project any distance from the rim B Fig. 2 and at any convenient part of
the same that suits my purpose.
The cover may also be made in any suitable metal earthenware or substance and
in any suitable or well known form, I make the cover to fit inside the top at the
point where the bed C Fig. 2 meets the rim B Fig. 2 so that the cover may rest' on
the bed C Fig. 2 and fit the rim B Fig. 2.
I then make on the inside of the rim B Fig. 2 two projections or "lugs "D', D³,
Fig. 2 these may be opposite to each other or at varying distances from each other
as may be wished and if desired there may be more projections than the two
mentioned, and I place the lugs at a sufficient distance above the bed C Fig. 2 to
enable the cover when at rest on the bed C Fig. 4 to be clear of the said lug
except under conditions as stated hereafter.
Now as will readily be seen the cover would be prevented from resting on the
bed C Fig. 2 by the projections, or "lugs" as I hereinafter call them; and in order
to allow the cover to pass I make a slot in the outer circumference of the cover A
Fig. 1 said slot or cut being sufficiently large to enable one of the projections or
lugs D1 D2 to pass through the said slot E now as will readily be seen the cover
may be placed on the bed C by bringing the slot E in the cover opposite the
lug D' or D' and placing the outer circumference of the cover at the point farthest
from the slot E opposite the lug D' or the lug D' as chosen in the manipulating
and working the same.
It is now apparent that the cover meets with no obstruction to its passage to the
bed C but can at once be lowered on to the bed C.
To affix the cover A to the top B all that is required is to turn the cover A
round while laying on the bed C'the cover A may be turned any proportion of a
circle as unless the slot E is brought opposite either of the lugs D' D' it is
impossible to remove the cover A from the top B. Where special security is required
against the lid or cover becoming detached from the top I may make one of
the lugs D', D' of larger size than the other, as may be seen by the slot E being
of only sufficient size to pass the smaller of the two lugs D1, D2 the cover A may
only be removed from the top B or attached to the same by the slot E passing the
smaller of the two projections or lugs D¹ or D'.
For the purpose of more perfectly securing the cover A to the top B 1 employ
the following method where. I consider the same desirable for my purpose, at the
outer circumference of the cover A at any distance from the slot E but generally
at a distance of about a quarter of the circumference from the same, I gradually
raise the upper edge F sufficiently to cause the cover to bind and tighten to the top
on a sharp twist or turn or even a slow firm revolving motion being given to the
cover A when at rest on the bed C on the raised outer edge coming under either of
the lugs D' or D and in order to give a better grip to the union I may slope the
under sides of the lugs-D to any desired angle or angles-as will be seen this forms
a means by which the union of the top and cover may be made perfect and
minimises the danger of the cover working round to the removing point.

page_text: To facilitate the affixing of the cover to the top and the removing or unfixing of
the same, I make any convenient grip or handle on the cover such as a loop for
the fingers, so as to give more power to affix or remove the cover and the top such
handgrip is shown at G Figs. 1 and 4.
To more easily explain the invention and the manner in which it is applied,
I append to this Specification drawings of the top and cover and a milk churn
showing as affixed to the same.
Figure 1 shows a plan and section of the cover.
Figure 2 shows a plan and section of the top.
Figure 3 shows an elevation of the cover showing the raised outer edge and the
handgrip.
Figure 4 shows the plan of the cover and top attached.
Figure 5.shows the cover and top as applied to a vessel used for holding and
conveying milk and generally called a milk churn.
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 what
I claim is:
1. The top or upper part of a churn, can or other vessel used for general
holding purposes having lugs or projections in the side thereof which hold down
a cover or lid to the flanged bed of the top as described herein before.
2. A lid or cover having a slot or cut in the outer circumferential edge of the
same of sufficient size to pass over the lugs or projections mentioned in Claim 1,
said slot permitting the cover to pass on to the bed as herein before described.
3. A raised part of the outer circumferential edge of the said cover which will
bind the cover to the top in the manner described when the said raised part comes
under or partly under the lugs or projections mentioned in Claim 1.
4. A handgrip on the cover to facilitate the fixing or removing of the cover to
or from the top.
5. The whole working and acting conjointly and in the manner as described in
this statement hereinbefore.
Dated this Thirteenth day of November 1894.
EDWARD MASKREY.
