"Improvements in Milk Cans and the like."
I, OSCAR MARTH of Neuhaldensleben in the Empire of Germany, Engineer. do
hereby declare the nature of this invention to be as follows:-
This invention has for its object a wooden cask-like vessel for conveying milk,
which is intended to avoid the drawbacks of the vessels hitherto employed in
which in the case of metal vessels a deleterious action on the milk is caused by
the unfavourable action of variations of temperature, whilst in the case of wooden
milk cans as the stopper is arranged in the middle of the lid, a considerable edge.
remains which remders very difficult the pouring out of the milk and the very
necessary cleansing of the vessel.
The wooden milk can forming the object of the present invention removes these
drawbacks, the can or vessel which is wide and roomy below, being reduced in
diameter towards the top, so that a closing device or stopper of ordinary dimensions
may be inserted to fit directly up to the walls, whereby when the stopper is
opened. the whole mouth of the can is free, and moreover the insertion of a special
lid the same as the bottom is dispensed with.
The vessel, which is composed in the ordinary way of wooden staves held
together by hoops and provided with a bottom, is so tapered or reduced in diameter
towards the top that whilst capacity is afforded in the vessel for sufficient cubical
contents, a metal ring may be inserted in its mouth by means of a screw thread
or the like, to carry the actual stopper.
A form of construction of the stopper which is well adapted for use with the
new can or vessel consists of a lid hinged to the ring, and adapted to be pressed
on the closing or washering surface or edge of the ring by a curved piece handle
or bail having a cam action. The lid is of softer metal than the ring, and con-
sequently the edge of the latter is pressed sufficiently into the lid to socure a.
tight joint. If the ring be made of softer metal, the washering edge must, on
the contrary, be made on the closing lid.
Any other suitable stopper lid or closing device may be employed in combina-
tion with the above described milk can or vessel which tapers towards the top,
such stopper being inserted in the ring lot into the mouth.

COMPLETE SPECIFICATION.
"Improvements in Milk Cans and the like.".
I, OSCAR MARTII of Neuhaldensleben in the Empire of Germany, Engineer, 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 has for its object a wooden cask-like vessel for conveving milk.

page_text: remains which readers very difficult the pouring out of the milk and the very
necessary cleansing of the vessel.
The wooden milk can forming the object of the present invention removes these
drawbacks, the can or vessel which is wide and roomy below, being reduced in
diameter towards the top, so that a closing device or stopper of ordinary dimensions
may be inserted to fit directly up to the walls, whereby when the stopper is
opened, the whole mouth of the can is free, and moreover the insertion of a special
lid the same as the bottom is dispensed with.
This improved can is shown in the accompanying drawings, in which:
Figure 1 is a vertical section;
Figure 2 a section of the fastener on the line ay of Figure 5 with the lid
closed.
Figure 3 a similar section with the lid open.
Figure 4 a section of the lid on the line s z of Figure 5.
Figure 5 a plan view of the lid.
The vessel a which is composed in the ordinary way of wooden staves held
together by hoops and provided with a bottom b is so tapered or reduced in dia-
meter towards the top that whilst capacity is afforded in the vessel for sufficient
cubical contents, a metal ring c may be inserted in its mouth by means of a screw:
thread or the like, to carry the actual stopper.
A form of construction shown in Figures 2 and 3 of the stopper, which is well
adapted for use with the new can or vessel, consists of a lid d hinged to the ring c
and adapted to be pressed on the closing or washering surface or edge of the ring e
by a curved piece, handle, or bail e having a cam action. This cam action may
be obtained by any ordinary mechanical means for instance in the manner shown
in the drawings, which is as follows:
A cross piece h is secured to the top of the lid d, the said cross piece having
upwardly extending ends 2, the tips of which are turned over outwardly, as
shown in Figure 4. These projections h h (which may if desired be directly.
formed on or connected with the lid without the cross piece h) have their tips
moreover shaped to a cam-form as shown in Figure 3. The handle or bail e is
pivoted in eye-brackets g and carries at each end a
plates are turned over inwardly to form claws e to engage over the cam-shaped
plate e the ends of which
tips of the projections h¹ h2 (see Figure 4). When the bail e is turned up, the
claws lie to one side (Figure 3) and allow the projections h¹² to pass and
the lid to be turned down on its hinge f and closed. After closing the lid the
bail is depressed thus causing the claws to ride over the cam-shaped tips of
the projections h h of the lid whereby the latter is forced tightly to its seating
(Figure 2). The lid is of softer metal than the ring, and consequently the edge el
of the latter is pressed sufficiently into the lid to secure a tight joint. If the
ring c be made of softer metal, the washering edge must, on the contrary, be
made on the closing lid.
Any other suitable stopper lid or closing device may be employed in combina-
tion with the above described milk can or vessel which tapers towards the top,
such stopper being inserted in the ring e let into the mouth.
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
claim is;-
1. A wooden milk can characterised by the walls of the downwardly widening
vessel (a) being contracted or tapered towards the top to receive a ring (c) which
holds any convenient or suitable stopper filling up the entire mouth, substantially
as described.

page_text: 2. In the herein described wooden milk can, a construction of stopper character-
ised by a lid d and a ring (c) made of metal of different hardness so that on their
being closed together with pressure the edge of the one part forms a tight joint
against the surface of the other part, substantially as described.
