IMPROVEMENTS IN MEANS AND APPLIANCES FOR SECURING MILK CANS AND OTHER ANALOGOUS ARTICLES TO THE EXTERNAL PARTS OF DOORS AND DOORWAYS
Year: 1885

page_text: I HERBERT PRICE LAVENDER of Cleveland Safe Works, Wolverhampton, in
the County of Stafford, Managing Director, do hereby declare the nature of my
Invention for IMPROVEMENTS IN MEANS AND APPLIANCES FOR SECURING MILK
CANS AND OTHER ANALOGOUS ARTICLES TO THE EXTERNAL PARTS OF DOORS AND
DOORWAYS 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 provide means whereby milk cans and other
analogous articles may be securely fastened to the outside of doors or door jambs
pending the opening of such doors by the inmates.
And in order that my said invention may be clearly ascertained reference is
hereby made to the accompanying drawings in which similar letters of reference
indicate corresponding parts.
Fig 1 is a side elevation of an ordinary milk can, a is the can, b the lid, c is the
ordinary wire handle; d is a fixed hook attached to the rim of the can, and e is a
clip hinged to the lid at e¹ as shown.
Fig 2 is an elevation of a rim lock which is fixed to a door, door post or door
jamb as shewn in Figs 4 and 5. f is the outer plate of the lock, which plate is
shewn removed in Fig 3 and the inside of the lock is seen-g is a catch which is
pressed downwards by the spring h. The rim of the lock is perforated at i for the
reception of the hooks d and e of Fig 1. k is a lever, which may be moved by hand
to the position k³ (shewn by dotted lines); and this movement of the lever raises
the catch g and disengages the clips d, e,-The end g¹ of the catch g is cut away
behind so as to allow the clips de to pass downwards to the position shown by
dotted lines in Fig 3, the bent end of e being caught and securely held by the end gl
of the catch g as shewn.
In Fig 4 m is a section of a portion of a door and n a portion of the door-jamb.
The lock is there shewn fixed to the door in which position the lever k is in contact
with the door-jamb, and the can cannot be removed until the door is opened and
the lever k thus set at liberty is moved outwards, as shewn in Figs. 2 and 3.
In Fig 5 the lock is shewn fixed to the door jamb, and the door m impinges
against the lever k and thereby prevents the removal of the can until the door is
opened and the lever k moved by hand as before described.

page_text: Although I have described the application of my invention to milk cans it
is obvious that, with suitable modifications it may be applied to other articles of
an analogous nature.
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
I claim is
1. The means and appliances for securing milk cans and other analogous articles
to the external parts of doors and doorways, substantially as herein before described
and shewn on the drawings.
2. The method of securing locks for the purposes aforesaid, by means of an
external lever k which is securely held in a locked position while the door is shut,
and only capable of being released when the door is open, substantially as herein-
before described and shewn on the drawings.
