I ALFRED DOMAN, of 12 Richmond Villas, Seven Sisters Road, Holloway, London,
in the County of Middlesex, Agent, do hereby declare the nature of my invention
for IMPROVEMENTS IN DOOR KNOBS FOR THE ATTACHMENT AND PROTECTION OF
MILK CANS, to be as follows:-
:-
By means of a knob and spindle the shoulder of which is partially filed to
receive the bail of a milk can, which when placed into position and the knob being
pushed towards the door, is forced into a slot in a rose or collar screwed to the
door, through which the spindle passes, the spindle being secured when thrust
through the door by a catch, so that the knob cannot be withdrawn unless
unfastened from the inside. The rose having a slot across the front to receive the
bail of the can, prevents the can from being shifted, and the knob from being
turned round or released from the outside whilst the can is attached to the door,
thus securing the can and preventing theft.
The spindle being notched on the top only, enables the user to turn round the
knob and withdraw it sufficiently to enable the can to be placed into position, the
end notch encircling the spindle prevents it from being entirely withdrawn through
the door.

I ALFRED DOMAN, of 12 Richmond Villas, Seven Sisters Road, Holloway, in the
County of Middlesex, Agent do hereby declare the nature of my invention for
IMPROVEMENTS IN DOOR KNOBS, FOR THE ATTACHMENT AND PROTECTION OF MILK
CANS, 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 this Invention is to secure milk cans from being stolen, and to
prevent the contents from being tampered with, when the dairyman leaves his
supply of milk at the consumers door; thus obviating the necessity of disturbing
the inmates, and saving time in delivery. For this purpose, I employ a knob and
spindle, as in Figure 1, the shoulder of which is partially filed away so as to receive
the bail of a milk can, this when placed in position, and the knob pushed towards
the door is forced into a slot in the rose or collar, (Figure 2) which is screwed
to the door, and through which the spindle passes, as in Figure 3, the spindle when
thrust through the door, being secured by a slide or catch, (shown in Figure 4)
which works on a plate fixed on the inside of door; hence the knob cannot be
withdrawn until unfastened by the inmates.
The rose or collar having a slot across the front, as in Figure 2, to receive the
bail of the can, this prevents the knob from being turned round or released from
the outside, whilst the can is in position as in Figure 5, thus forming a perfect lock
when in actual use.
The spindle of knob being notched on the top only, enables the user to turn
round the knob and withdraw it sufficiently, for the can to be placed in position;
the end notch encircling the end of spindle, prevents it from being entirely with-
drawn through the door.
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
1st A knob with spindle, the shoulder of which is made to receive a wire bail,
and the body and end of which spindle is notched so that it may be secured by
the catch on the inside of door.
2ndly A rose or collar with a slot cut across the front to receive a wire bail of a
can; this combined with the knob described above being so arranged to operate
substantially as hereinbefore described.
