Complete Specification Accepted, 14th Dec., 1888
I, EDWIN JAMES MUTTON, of 14, Market Street, Cambridge, in the County of
Cambridge, do hereby declare the nature of this invention to be as follows:-
My invention relates to milk-cans of that class which is used for transporting milk
on railways, and the object of my invention is to provide means for facilitating the
handling of the same.
According to my said invention the projecting ventilator which is formed on the
lid or cover of the can and which is usually held in one hand whilst rolling the can
along, is provided with a rotatable cap or ring. This cap or ring is preferably mounted
upon a pivot secured to the top of the ventilator but it may be arranged in any other
suitable manner.
In rolling a can along, this cap or ring enables the can to be held firmly, the
ventilator rotating within the cap so that no motion is imparted to the latter.

page_text: Improvements in Milk Cans.
I, EDWIN JAMES MUTTON of 14 Market Street Cambridge in the County of
Cambridge, Ironmonger 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 refers to circular Milk "trunks" or "churns" as they are termed
being the cans now employed for conveying Milk by Railway, and is designed to
facilitate the moving of the said cans and also to ventilate them without letting the
Milk escape when they are moved.
In the accompanying drawings
Fig. 1 shews a full size sectional elevation of my ventilator and revolving cap.
Fig. 2 shews a section of the rotating cap.
Fig. 3 shews a section of the ventilating cone and spindle.
Fig. 4 shows a view of the washer employed to fasten the cap.
It will be seen that my invention consists of a small hollow fixed cone or cylinder A,
with horizontal ventilating perforations B, surmounted by a truncated revolving
cap C, which is substituted for the centre lid ventilator usually employed. My
cone or cylinder is so fixed in the centre of the slightly convex horizontal cover of the
can shewn by the dotted lines T, that about half its length projects below the line of
the cover, the ventilating holes in the cone being above the cover. Shortly above the
the ventilating holes, the cone or cylinder ends, and is contracted into or surmounted
by the circular metal stud, or pin, which forms the spindle D, upon which the circular
cap C revolves.
This cap has a tubular centre E, forming a bearing to fit and revolve upon the
spindle D, and is constructed of convenient size for being held in the hand of any-one
moving the can. It is attached to the spindle so as to revolve freely thereon, but
cannot escape therefrom being fastened by the washer F, which fits into a recess in the
said cap and is formed with a countersunk hole G, in its centre fitting over the
contracted end H, of the spindle D, in such a way that the said end H, is easily
rivetted down flush into the said counter sunk hole of the washer, and the cap'C, is
thus firmly attached to the cone.
The advantages of my cone and smooth revolving cap are (1) That the can, may
be easily rolled or trundled along the ground upon its hooped ring or foot without
removing the hand from the cap, and without fear of lacerating the hand, as often
happens with the centre ventilator now usually held for this purpose. Moreover (2)
ventilation is secured by the inserted cone with air holes above the line of the cover,
without fear of spilling the milk when rolling the trunk.
My cone or cylinder and revolving cap, can be made of malleable iron tinned to
prevent oxydation, or of other suitable metal.

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,
•
1st. A fixed ventilating cone or cylinder for insertion in the covers of milk trunks
or cans the said cone terminating in a spindle upon which a cap revolves, the said cap
forming a rotating handle or knob, by means of which the removal of the can is greatly
facilitated, as herein explained and set forth.
2n1: A rotating cap or knob revolving on a hollow fixed cone or cylinder the said
cone being inserted partly below the line of the cover and having air holes above the
said line for ventilation as herein explained and set forth.
