COMPLETE SPECIFICATION.
Improvements relating to Railway Milk Cans.
I FRANCIS HABGOOD FREETH of Victoria Works, Wandsworth Road, in the
County of Surrey, Dairy Utensil Manufacturer, 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 this invention is to provide means for preventing the lids or covers
of railway milk cans from accidentally coming off during transit or when being
trundled about. The invention comprises a double ended pivotted piece which is
In the
carried by a hinged elbow piece secured to the lid or cover of the can.
neck of the can is an aperture in the path of the pivotted piece and when the latter
has been passed therethrough it falls down under the action of gravity and forms a
catch securing the lid or cover to the neck of the can.
The accompanying drawings are furnished in illustration of the invention.
Figure 1 is a vertical section of part of a railway milk can and lid with the
invention attached thereto.
Figure 2 is an enlarged perspective view shewing part of the lid alone, and
Figure 3 is a plan of the fastening device.
The same letters of reference are used to indicate the same or corresponding parts
where they occur in the several figures.
A is the base of the fastening device by which it is firmly secured to the lid or
cover B in any suitable manner. C is an arm hinged or pivotted at D to the base A
and at its upper end turned over at right angles or thereabouts as shewn at E.
The piece E is bifurcated or cut away in the centre as shewn in Figure 3 and
between the cheeks so formed, the double ended piece F is eccentrically pivotted
at for it may be centrally pivotted and counterweighted at its outer end so as to
fall down under the action of gravity into the position shewn in Figure 2 and by
the full lines in Figure 1. The pivotted piece F may if so desired be pivotted on
one side or on both sides of the fixed piece E or two such pivotted pieces may be
pivotted one on each side of the fixed piece E.
'
The lid or cover B is placed in position on the can H and is fastened to the
neck G thereof in the following manner :-The arm C is turned down on its hinge
or pivot D towards the lid or cover B into the dotted position-shewn in Figure 1
and the double ended piece F is then lifted until it is in alignment with the side or
sides of the fixed piece E. The arm C is then turned forward on its pivot D and
the fixed piece E and pivotted piece F are together passed through an aperture g
made in the neck G of the can purposely to receive them. When the arm C is
close against the inside of the neck of the can, the pivot on the piece E will have
passed completely through the material of the neck of the can and will be outside,
when the double ended piece F will fall by gravitation into the position shewn in
Figure 1. In this position the two ends of the piece F will bridge over the
aperture g in the neck of the can and will prevent the lid or cover from becoming
detached from the can. To unfasten the device it is only necessary to lift up the
pivotted piece F into line with the fixed piece E as shewn by the dotted lines in
Figure 1 when the fastening can be withdrawn from the aperture g as will be
understood from the foregoing description.
If desired the piece E with the double ended piece F pivotted thereto may be
secured to the interior of the neck of the can and the arm C provided with an
aperture to receive them, but the arrangement shewn in the drawings is preferable
as when the lid or cover is removed there is no projecting part on the interior of
the neck of the can which may be cleaned or otherwise manipulated in the ordinary
way without inconvenience.

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 device such as herein described for detachably fastening the lid or cover to a
railway milk can consisting of a double ended pivotted piece counterweighted, or
eccentrically pivotted to a fixed piece forming part of or secured to an arm hinged
or pivotted to a base secured to the lid or cover said device engaging with an
aperture made in the neck of the can, through which said aperture the fixed piece
and the counterweighted piece can be passed when brought into line with one
another substantially as described..
2. For detachably securing the lid or cover to a railway milk can, a gravitation
fastening such as is hereinbefore set forth operating substantially in the manner
.described.
