page_text: I, THOMAS GRAYSON, of 16, Queen Street, Derby, in the County of Derby,
Coppersmith, do hereby declare the nature of this invention to be as follows:-.
The object of my invention is to provide an improved dust proof lid or cover
for railway milk churns and also to protect the ventilator and labels affixed on
or to the said cover from being damaged.
I am aware that a dust proof cover for railway milk churns is not novel but
such covers have usually been made, in common with the ordinary cover, with a
downwardly projecting bottom rim fitting inside the top of the churn, this is a
great harbour for dirt and very difficult to keep clean and sweet; while in the
case of the usual dust proof cover fitting over the top edges of the churn the venti-
lator projects upwards and is liable to get knocked off or damaged and the label
which is usually fixed on the top of the cover is liable to be defaced or knocked
off, and further, when "bowling" the churn along the operator cannot see when
the milk is escaping until it is pouring out between the overhanging edge of the
cover and the top of the churn.
My invention is designed to overcome these difficulties and in carrying the
same into effect I form the cover of a slightly convex section with an upwardly
projecting rim or flange all round, the top outside edge of the said rim projecting
slightly, so that the whole fits down upon a double internal rebate in the top of
the churn, the lid is placed sufficiently low down in the top of the churn to pro-
tect the ventilator placed in its centre from being damaged and when bowling
the churn along the operator will be enabled to see the milk when escaping
before it reaches the top edge of the churn, while any dust that may fall on the
top of the lid or cover will remain there until it is washed off instead of passing
into the interior of the churn as is the case with a many of the ordinary covers

label being fixed on the top of the cover cannot be readily defaced before it
reaches its destination.
The churn top is preferably made of malleable iron and has a lug or projec-
tion cast on inside which fits into a corresponding recess in one side of the cover
and so dispensing with the usual loose castings which are continually getting
knocked off; on the opposite side of the cover I provide a hasp and staple or any
other suitable means of fastening same down. By these means the whole of the
lids will be interchangeable.

page_text: Improvements in and relating to Railway Milk Churn Lids or Covers.
I, THOMAS GRAYSON, of 16, Queen Street, Derby, in the County of Derby,
Coppersmith, 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 my invention is to provide an improved dust proof lid or cover
for railway milk churns and also to protect the ventilator and labels affixed on
or to the said cover from being damaged.
I am aware that a dust proof cover for railway milk churns is not novel but
such covers have usually been made, in common with the ordinary cover, with a
downwardly projecting bottom rim fitting inside the top of the churn, this is á
great harbour for dirt and very difficult to keep clean and sweet; while in the
case of the usual dust proof cover fitting over the top edges of the churn the venti-
lator projects upwards and is liable to get knocked off or damaged and the label
which is usually fixed on the top of the cover is liable to be defaced or knocked
off and further, when "bowling" the churn along the operator cannot see when
the milk is escaping until it is pouring out between the overhanging edge of the
cover and the top of the churn.
My invention is designed to overcome these objections and in describing the
same, reference will be had to the accompanying sheet of drawings upon which
Figure 1 is a vertical transverse section through the top and cover of a churn
constructed according to my invention.
Figure 2 is a section shewing an alternative section of top and cover as will
be hereinafter explained.
Figure 3 is an elevation from the inside shewing the back junction of the
churn top and cover to be also hereinafter further explained.
In carrying out my said invention I form the cover A of a slightly convex
section with an upwardly projecting rim or flange A¹ all round, the top outside
edge A² of the said rim projecting slightly, so that the whole fits down upon
a double internal rebate 13 B2 in the top B of the churn, the lid or cover A.
is placed sufficiently low down in the top of the churn to protect the ventilator C
placed in its centre from being damaged and when bowling the churn
along the operator will be enabled to see the milk when escaping before
it reaches the top edge of the churn, while any dust that may fall on the
top of the lid or cover will remain there until it is washed off instead of passing
into the interior of the churn as is the case with a many of the ordinary covers
in use when in transit or when the cover is taken off. For the same reason the
label being fixed on the top of the cover cannot be readily defaced before it
reaches its destination.
The churn top is preferably made of malleable iron and has a lug or projec-
tion B cast or fixed on inside which fits into a corresponding recess A³ in one side
of the cover and so dispensing with the usual loose castings which are continually
getting knocked off; on the opposite side of the cover I hinge a staple 1) the
cuter end of which passes through the side of the churn top, this staple fits over
a pierced lug E fixed to the side of the cover so that a lock, split ring or peg may
he passed through the hole in the lug and hold the lid securely in position.
The ventilator is preferably given a slight projection below the underside of
cover to stop the milk or the like splashing out of the holes F therein.
Instead of forming the churn top with a double rebate inside, I may form it

page_text: with a single one as shewn at B on Figure 2 and adopt the simple form of cover
rim A' thereon illustrated.
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:
The improvements in the tops and lids or covers of milk churns substantiaily
as described herein and illustrated on the accompanying sheet of drawings.
