COMPLETE SPECIFICATION.
An Improved Fastening for Securing Milk Cans or other Articles
to Doors so that they Cannot be Removed by Unauthorized
Persons.
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 :-
This invention has for its object the protection of milk cans left at the doors by
milkmen in the early morning before the occupants of the houses are about.
This invention will be better understood by reference to the enclosed plate of
drawings.
Fig. 1 is an end view of protector or fastening shewing mortice for catch.
Fig. 2 is the opposite end view shewing mortice for finger press of traveller.
Fig. 3 is a section shewing screw and tapped plate for connecting top and bottom
plates together.
Fig. 4 is also a section shewing the internal fittings viz.: traveller, wire spring,
screw for fixing top and bottom parts together, guide for traveller stop for spring
also the catch to be attached to milk can handle.
Fig. 5 is a horizontal section through door jamb and part of door with the
protector or fastening fixed to door jamb.
Fig. 6 is a projected view of same.
"
Fig. 7 is a vertical section through part of rail of door shewing face edge of door
jamb with can protector or fastening in position for holding the " can; the face of
protector or fastening used as an advertising medium.
In manufacturing the aforesaid invention, the two circular caps forming the case
and cover can be either cast brass or iron or stamped brass iron, zinc or tin; also
the traveller A shaped for finger press at D and rebated out for spring B, can either
be cast or stamped; the spring B I make of brass wire, the part GI either form
in a solid block or turn down as shewn; the two screws L are for fixing protector
or fastening to the door jamb after which I screw on the cover part of protector by
means of the screw K Fig. 3 and secure same in position with set screw M which
being the door side of protector or fastening cannot be turned back while the
door remains closed; the stud or pin C forms a stop for the traveller A and a
thrust for spring B the rim F is a guide for traveller A in lieu of which I can use
2 pins fixed to bottom plate; E is the catch in which is formed the slot H into
which the handle of the milk can is placed; to prevent the said catch from being
easily detached from the milk can I insert a small steel spring I which while
preventing the catch falling from the handle of the can, when released from the
latch; does not prevent it from being easily removed when so required.
I do not limit the use of my invention for milk cans only.
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 circular latch having traveller, and spring as before described which can
only be operated upon to release the catch when the door of dwelling is open, the
latch being affixed to the door jamb of the said door.
2nd. A circular cover plate with rim, attached by means of a screw and kept in
position by means of a set screw, which can only be turned when the door is open
thus preventing the latch being detached from the door jamb without first opening
L1

page_text: 3rd. A metal catch with slot in same for the insertion of the milk can handle,
having a small steel spring to prevent same being too easily detached from the can
handle.
4th. In a milk can protector a medium for advertising as shewn on plate of
drawings.
