PROVISIONAL SPECIFICATION left by the said Henry Harris Lake at the
Office of the Commissioners of Patents on the 19th September 1881.
HENRY HARRIS LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN CANS OR VESSELS FOR
THE TRANSPORT OF MILK." A communication from abroad by Ferdinand
Fleischmann, of Moedling, Austria.
This Invention relates to improvements in cans or vessels to contain milk
which has to be conveyed from one place to another by railway or otherwise.
In constructing a can or vessel according to my Invention I provide a cylindrical
body or shell to which an inner bottom piece is attached by a lap-joint, and over
this part is placed an outer ring, within which and below the said bottom piece is
fitted a disc of hard-wood, the latter being hermetically enclosed by a second or
outer sheet metal bottom piece carefully soldered into the said ring. The body or
shell is also stiffened or strengthened by several hoops or rings of iron placed at
intervals around its circumference, these rings being designed to protect the can as
far as possible against being crushed; the upper end of the shell or body has a
neck somewhat in the shape of an inverted funnel, this being attached to the
cylindrical part by a lap-joint. The lid of the can forms a vessel with a rounded
body, whose upper edge is curved outward and downward, so as to form a groove
of semicircular cross section, within which there is an india-rubber ring. A bridge
piece is fixed on the upper edge of the lid and is rounded off at both ends; it not
only serves as a handle for the lid, but its ends take the pressure required for
keeping the lid tight. This lid is moreover provided with a protecting ring, one
part of which extends within and is securely soldered to the lid, the upper portion

page_text: of the ring extending above the lid and being supported at a shouldered portion
upon the raised rim formed by the outwardly curved portion of the lid. The
object of this protecting ring is to take violent thrusts from the top to which the
can is exposed, especially when full during unloading, thus preventing the closing
devices being injured.
Upon the lid a bracket is also provided corresponding with an angle piece upon
the neck of the can in such a manner that when the latter is closed the bracket
will be exactly over the angle piece and a lug upon the said bracket will abut
against the angle piece. This bracket is rivetted securely upon the protecting
ring of the lid. In some cases I may, however, dispense with the protecting ring,
and then the bracket will be of somewhat different shape, and must be fixed on the
lid itself.
At the upper part of the can two curved cross pieces are provided, one on each
side, both being rivetted to the can. At the upper part, that is to say, in the
centre of each curve, there is a pivot, and upon these pivots the ends of a curved
lever are placed, so that they may move freely thereon, the ends being excentric.
This lever is free to rotate in a semi-circle around the pivots, and the arrangement
is such that the two excentrics press upon the ends of the aforesaid bridge piece,
and consequently upon the lid when the said lever is pulled downward. When
the lever is brought down so that it rests upon the aforesaid bracket a pad-lock can
be inserted within the three parts, viz., the angle piece, the bracket, and the lever,
so that the contents of the can may be protected from being abstracted. Instead
of a pad-lock, string, the ends of which are to be secured by lead, may be used, in
which case for perfect safety the string has also to be passed through the small lug
on the bracket. The lid fits within the neck of the can, and its bottom is rounded
for the purpose of allowing all the air to escape; moreover, said lid is hollow to
provide a space together with that enclosed within the protecting ring for the
reception of ice designed to keep the milk cool; the capacity of this space can be
increased by cutting out the centre of the bottom of the lid and providing it with
a downward extension.
On the top-edge of the protecting ring a hinged lid is placed to prevent the ice
being jerked out during transport. The hinged lid is made to snap, and has on the
side opposite to the hinge a lug with a hole through which the string can be drawn
when string is used.
.1
In-cases-where-the-fastening_is_not_required_to be so perfect as that above
described I modify the construction of the devices as follows, that is to say, instead-
of the two cross pieces with the excentric lever I provide upon the can at
opposite points two uprights, with eyes or loops, under which the rounded off part
of the bridge-piece can be inserted, so that the lid is kept down sufficiently firm;
the india-rubber ring is also omitted in a can of this construction. A bail or handle
by which to carry the can is inserted in the two uprights.

HENRY HARRIS LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. " IMPROVEMENTS IN CANS OR VESSELS FOR
THE TRANSPORT OF MILK." A communication from abroad by Ferdinand
Fleischmann, of Moedling, Austria.
This Invention relates to improvements in cans or vessels to contain milk which
has to be conveyed from one place to another by railway or otherwise. In the
accompanying Drawing,―
Figure 1 is a vertical central section of a can made in accordance with my
Invention.
Figure 2 is a side elevation of a portion of the same.
Figure 3 is a plan of the same.
Figures 4 and 5 show the lid provided with a receptacle for ice.
Figure 5* is a separate view of the bracket p.
Figures 6, 7, 8, 9, 10, and 11 are detail and other views shewing the can with
a fastening of simple construction.
In constructing a can or vessel according to my Invention I provide a cylindrical
body or shell A to which the bottom piece B is attached by a lap-joint, and over
this part is placed an outer ring D, within which and below the said bottom piece
is fitted a disc m of hard wood, the latter being hermetically enclosed by a second
or outer sheet metal bottom plate b carefully soldered into the said ring. The
body or shell is also stiffened or strengthened by several rings D of hoop iron
placed at intervals around its circumference, these rings being designed to protect
the can as far as possible against being crushed. The upper end of the shell or
body has a neck C somewhat in the shape of an inverted funnel, this being
attached to the cylindrical part by a lap-joint. The lid of the can E forms a
vessel with a rounded body, whose upper edge is curved outward and downward
BO as to form a groove of semi-circular cross section, within which an india-rubber
ring is fitted. A bridge piece F is fixed on the upper edge of the lid and is
rounded off at both ends; it not only serves as a handle for the lid, but its ends
take the pressure required for keeping the lid tight. This lid is moreover provided.
with a protecting ring R, Figures 1 and 2, one part of which extends within and
is securely soldered to the lid E, the upper portion of the ring extending above
the lid, and being supported at a shouldered portion upon the raised rim formed
by the outwardly curved portion of the lid. The object of this protecting ring is
to bear the violent thrusts from the top to which the can is exposed especially
when full during unloading, thus preventing the closing devices from being
injured.
Upon the lid a bracket p is provided corresponding with the angle piece k upon
the neck of the can, in such a manner that when the latter is closed the bracket
will be exactly over the angle piece k, and a lug upon the said bracket will abut
against the angle piece k. This bracket p is rivetted securely upon the protecting
ring of the lid. In some cases I may, however, dispense with the protecting ring,
and then the bracket will be of somewhat different shape (see Figure 9), and must
be fixed upon the lid itself.
At
At the upper part of the can two curved cross-pieces G, G', are provided, one on
each side, as shewn in Figures 1, 2, and 3, both being rivetted to the can.
the upper part, that is to say, in the centre of each curve there is a pivot Z, Z¹,
and upon these pivots the ends of a curved lever H are placed, so that they may

page_text: move freely thereon, the ends of the said lever forming excentrics. This lever is
free to rotate in a semi-circle around the pivots Z, Z', and the arrangement is such
that the two excentrics press upon the ends of the aforesaid bridge-piece F, and
consequently upon the lid when the said lever is pulled downward. When the
lever is brought down so that it rests upon the aforesaid bracket a padlock can
be inserted within the three parts, viz., the angle piece k, the bracket p, and the
lever H, so that the contents of the can may be protected from being abstracted.
Instead of a padlock a string, the ends of which are to be secured by lead, may be
used, in which case, for perfect safety, the string has also to be passed through
the small lug on the bracket p.
In use the can is filled up to where the neck assumes a cylindric shape, then the
lid is inserted in the neck of the can after the lever H has been raised into the
position shewn in dotted lines in Figure 1. The lid fits within the neck of the
can, and its bottom is rounded for the purpose of allowing all the air to escape.
When the lid is inserted it is rotated until the downwardly extending lug of
the bracket p abuts against the angle piece k. The lever H is then depressed
towards the right, as shown in Figure 2, until it rests upon the bracket p, and the
can is provided with a padlock or string in the manner hereinbefore described.
The lid E of the can is hollow to provide a space together with that enclosed
within the protecting ring R for the reception of ice designed to keep the milk cool;
the capacity of this space can be increased by cutting out the centre of the bottom
of the lid and providing it with a downward extension S, see Figures 4 and 5.
On the top edge of the protecting ring a hinged lid M is placed to prevent the
ice from being jerked out during transport. The hinged lid M is made to snap,
and has on the side opposite to the hinge a small lug with a hole through which
the string can be drawn when string is used.
In cases where the fastening is not required to be so perfect as that above
described, I modify the construction of the devices, as shewn in Figures 6, 7, 8, 9,
10, and 11, that is to say, instead of the two cross pieces with the excentric lever H
I provide upon the can at opposite points two uprights X, X', with eyes or loops,
as shewn; under the said eyes the rounded off part of the bridge-piece F can be
inserted so that the lid is kept down sufficiently firm, and the india-rubber ring is
als omitted in a can of this construction. A bail or handle T by which to carry
the can is inserted in the two uprights X, X', see Figures 6 and 7.
Having thus fully-described-the-said.Invention_as_communicated_to_me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
The general construction of milk-cans, substantially as described and as shewn
in the accompanying Drawing.
In witness whereof, I, the said Henry Harris Lake, have hereunto set my
hand and seal, this Eighteenth day of March, in the year of our Lord One
thousand eight hundred and eighty-two.
HENRY H. LAKE. (L.S.)
