Improved Method of Delivering Milk at House Doors, and Apparatus
for use therein.
I, HAROLD DOUGLAS HARRIS, of 7 Salisbury Square, Cathays, Cardiff, ironmonger,
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 consists in an improved method of and appliances for facilitating and
expediting delivery of milk at house doors.
According to this invention a passage, having a downward inclination towards the
back, is made through the door and in this passage is fitted a tube. The inner end
of the passage is normally obstructed by a plate pivotted to the door and furnished
at one end with a hook and at the other with a counterbalance.
When the counterbalanced plate is in its normal position the hook is uppermost
and the channel in the door is obstructed at the inner end, but by turning the plate
on its pivot, and thereby reversing the positions of the hook and the counterbalance,
an aperture in the plate is brought to coincide with the inner end of the channel in
the door, and an unobstructed passage is obtained.
If, now, a can or other vessel for the reception of milk be suspended from the hook
the counterbalanced plate is thereby held in the position to which it has been moved,
namely having the hook lower most. The means whereby the milk is delivered into
the vessel thus suspended behind the door consists of a funnel the stem of which is
inserted in the vessel by the milkman through the channel provided in the door.
The outer end of the channel in the door may be protected by a hinged or sliding
guard plate.
Referring to the accompanying drawing, Fig. 1 thereon represents a vertical section
of a door fitted, in accordance with this invention, with appliances for use in delivering
milk.
C
Extending through the door a is a passage in which is fitted a tube or throat b.
At the back of the door is a plato e pivotted at d to the door, or to an intervening
plate e,
The plate c, in which is an aperture, is furnished at one end with a
and at the other end with a counterweight h.
hook
In the normal position of the plate e the hook g is uppermost and while this is so
the channel bis obstructed and closed at the inner end by the plate c, but if the
plate e be turned on its pivot d so as to bring the hook to the lowermost position,
the aperture in the plate coincides with the inner end of the throat, and the passage
through the door is made free. In this position the plate c is held by hanging the
can, or other vessel, to the hook g. Fig. 2 represents, in elevation, the back of the
door and shows the plate c in the position it occupies when the can is suspended to
the hook g.
Milk is poured into the can from without through a funnel such as k carried by
the person who delivers the milk. When the can is removed, the plate c swings
round on its pivot d and closes the inner end of the channel b, as seen at Fig. 3.
The outer end of the channel is protected by a swinging guard plate 1, as seen at
Fig. 4 which represents an exterior view of a part of the door a.
By the adoption of the above described method and means the delivery of milk
is expedited, being made direct into houses without regard to the presence or absence
of a person or persons therein.
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 :-
1. The provision. nt the book of
an outer door of a

over the inner end of an inclined throat such as extending through the door, the said
plate closing the throat at the inner end when the counterweight is lowermost, but
leaving the passage free when the counterweight is uppermost, substantially as herein-
before described and for the purpose specified.
2. The combination, for the purpose of expediting and facilitating the delivery of
milk into the interior of houses, of an inclined throat or channel extending through
an outer door, a swinging counterbalanced plate such as c at the inner end of the
channel, a funnel such as kand a vessel for suspension to the said swinging plate,
substantially as herein before described.
