PROVISIONAL SPECIFICATION.
An Improved Fastening for Milk Cans, to Prevent the Lid being
Raised by Unauthorized Persons when Left at the Door of
Dwelling.
CHARLES HEATH 40 Lena Gardens Hammersmith Builders Foreman do hereby
declare the nature of this invention to be as follows :-
The object of my invention is to prevent rival milk retailers and others from
tampering with or injuring in any way, or stealing, the milk left at the doors of the
various dwellings in towns or other places.
To accomplish this I use a hasp of metal fastened to the lid of the milk can in
such a manner that it moves as on a centre; at a certain distance from the bottom
of the can I affix a metal staple or bow, to this bow is attached by means of a hole
passing through it a metal catch.shaped to fit the latch which is the subject of
Patent No. 16853 1891, the hasp being furnished with a slot or chase through which
the aforesaid catch passes, which having assumed a horizontal position is now forced
into the latch and so the lid of the milk can is securely fastened down until the
catch has been released from the latch by the owner of the milk or whomsoever
may be authorized to receive it.
In the case of high caus or where specially desired I affix to the lid a metal drop
eye and to the body of the can I slot on a metal hooking piece which engages with
the eye and by bringing the catch into a horizontal position and forcing it into the
latch (which is the subject of a Patent taken out by me being No. 16853 1891).
To improve the appearance of the fastening and to make it more useful I attach
to the hasp a moveable plate or tablet upon which I engrave or otherwise inscribe
the name of the dairy from which the milk has been procured or a description of
nursery milk
new milk this can form a part of the hasp
the said milk such as
9966
or be of a temporary character removable at the will of the owner.
My invention in brief consists of
1st. A hasp of metal (either as a whole or as before described) attached to the
lid of milk can slotted or chased to receive catch.
2nd. A bow or staple affixed to the body of milk can at a certain distance from
the bottom of the said can.
3rd. A catch being a piece of metal with a hole at one end for fitting to bow or
staple, the other end shaped to fit latch the subject of Patent No. 16853 1891.
4th. A label attachment whether of a temporary or permanent character.
Dated this 19th day of December 1891.

CHARLES HEATH 40 Lena Gardens Hammersmith London W. Builders
Foreman 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 prevent rival milk retailers and others from
tampering with the milk left at the doors in the early morning, to accomplish this
I use a hasp of metal part of which I solder to the lid of the can the other portion

page_text: works upon the aforesaid part as upon a.centre, this part is slotted and shaped; but
to better understand the construction and details of the invention, reference must be
made to the accompanying plate of drawings.
Figs. 1, 2, 3 & 4 illustrate the different heights of milk cans now in use in the
dairy trade, there are some higher and a few not so high, but to accommodate my
invention to them will not alter the principle of the invention.
Fig. 1 treat as a "high can" and to prevent the hasp being in the way (if
constructed as for lower cans) I fasten a part of the same to the body of the can
B is a sectional view of this part of the hasp and I also shew a front view of same in
which a is a slotted hole punched in the hasp which forms a hook, b is a slot punched
in hasp through which is passed the screw e this screw is tapped and soldered to
face of can and forms a guide and stop for hasp, c is also a slot to take catch g
which will be hereafter explained: A is a section through the wire ring with part
squared out from the circle, which forms a centre upon which the drop stubb works
(a front view also of this part is shewn) the wire ring is soldered to the top of the
can lid as shewn in Fig. 1 so that the stubb drops down on the front of the can and
when the hasp B is raised to its full height the sail drop stubb passes through the
hole a and as the hasp drops down by its own weight the narrow part of the stubb
passes up the slot as seen in Fig. 1 is a staple soldered to face of can which forms
a guide to hasp and a centre upon which works the catch g, this catch has a hole
drilled or punched at the back end through which the said staple passes this hole is
drilled or punched as close as possible to the bottom side (so that when not in use it
may easily fall down in front of the hasp) but a much greater distance is allowed
from the end of the catch so that when placed in a horizontal position it passes
through the slot c in hasp and fits tight to the front of the can by this means the
hasp is kept down to its lowest point and as the drop stubb d has been passed into a
it is impossible while the catch remains in a horizontal position to raise the lid of
the can; the other end of the catch is shaped to fit latch which is the subject of
invention Patent No. 16853 1891; the said latch being fixed to the door jamb as
described in the aforesaid Specification the catch being forced into the latch, is kept
in a horizontal position until the catch is released from the latch in the manner set
forth by that Specification.
my
Fig. 2 is a section through the front of a smaller. or lower can C is an elongated
front view of hasp is the staple fastened to the front of can upon which the
catch g is secured as in Fig. 1, the slot in this hasp (of which a front view is given)
is long enough for catch y to pass through, to secure the lid the catch is passed
through the slot in the hasp, the catch being brought into a horizontal position
tightens down the hasp and being kept in that position, by being secured to the
latch it is impossible to raise the lid until the catch has been taken out of the latch
by the person authorized to do so and in the manner described in Specification
No. 16853 1891.
Fig. 3 is a smaller can, the staple is soldered to the face of can to form a centre
for catch g to work on, the hasp differs but little from C, the straight part of
ring is turned up sufficient for the part X of hasp to work on: I prefer to bend
this part of the hasp rather quickly as by doing so the lid is pressed tightly down
as the catch is brought into a horizontal position as described for other cans, the
hasp CI prefer in some cases to bend, but for simplicity of manufacture I make
it straight as illustrated. With this and smaller milk cans I sometimes prefer as
in Fig. 4 to make the staple as in Fig. 3 but the back end of catch I allow.long
as for high cans, on the lid of these cans I solder on the ring as at front view of A5
without the drop stubb, a small piece is then cut out of the under side of catch
to permit same to fit tight on top of can lid, the catchy being brought into a
horizontal position and being so secured as before described, and as the milk can
cannot be placed much out of the perpendicular through coming in contact with
the door frame the lid cannot be raised until catch g has been released from the 5
latch.
The ring which forms a part of the hasp in Figs. 1, 2, 3 and as a guide for
