PROVISIONAL SPECIFICATION.
Improved Means and Appliances for Delivering Milk to Houses.
We THOMAS MARNS of 12 Rokeby Street Engineer, and JOSEPH WILLIAM
MARNS of 45 Bramwell Street Grocer, both of "Sunderland in the County of
Durham, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide improved means and appliances for
the better delivery of milk from house to house, whereby the necessity of the door
being opened is obviated while complete security against theft and malpractices is
assured.
According to our invention we provide in the house door an aperture of any con-
venient shape and size with a corresponding cover hinged at its base and opening
outwards and provided with a suitable iock and key. In a simple arrangement on
the inner side of this cover is fitted a detachable funnel below which upon the door
is placed the vessel for receiving the milk. Where more than one delivery is to be
made to one house more than one vessel is arranged below the said funnel, which
is then made capable of some swivelling motion on and about its support
so that its discharge orifice can be directed to each or any of the said vessels
to be filled.
To provide against fraud malpractices and accidental waste of milk we may
provide a check on the lock. This may consist of a catch acting on the cover, or a
stop or other device acting on the latch of the lock, controlled by the milk vessel
itself so that the said cover is always held locked and cannot be opened even by its
proper key until and unless the milk vessel is in the proper position for filling ;
but when the vessel is in position its weight frees the catch or lock and the cover
can be opened by its key. When the distributor's funnel is inserted to deliver the
milk it displaces a movable lever flap or other part and so causes the vessel to be
displaced, so that when the cover is reshut it cannot be again opened until the vessel
has been replaced in its proper position.
Any number of vessels may be provided and attached one behind the other, and
to prevent milk being spilled in case the second or other inner vessel is not in
position, we provide for each vessel an aperture with flaps in one side and a
projection on the other side, so that when the vessels are placed in position the
projections will open the flaps and allow the passage of the shoot, but the flap of
the outermost vessel is always closed and the further passage of the milk shoot
prevented.

COMPLETE SPECIFICATION.
Improved Means and Appliances for Delivering Milk to Houses.
We, THOMAS MARNS of 12 Rokeby Street, Engineer, and JOSEPH WILLIAM
MARNS of 45 Bramwell Street, Grocer, both of Sunderland in the County of
Durham, do hereby declare the nature of this invention and in what manner the
sanie is to be performed to be particularly described and ascertained in and by the
following statement :—
This invention has for its object to provide improved means and appliances for
the better delivery of milk from house to house, whereby the necessity of the door
being opened is obviated while complete security against theft and malpractices is
accused

page_text: We will now particularly describe our invention in reference to the accompanying
drawings in which like letters refer to.like parts;
.
Figure 1 is a vertical section of one form of appliance:
Figures 2 and 3 respectively are internal and external clevations thereof showing
the cover closed and open.
A is the house door in which according to our invention we provide an aperture a
of any convenient shape and size and to it we fit a corresponding cover Chinged
at to the door or to a frame e and opening outwards for a suitable distance
limited by a stop such as it is provided with a suitable lock L with catch
engaging the frame, and suitable key. In a simple arrangement to the inner side
of the cover is fitted a detachable funnel F shown hooked on at f, below which
upon the door is placed the vessel V for receiving the milk. When more than
one delivery is to be made to one house more than one vessel V is arranged one
alongside another on the door below the said funnel, which is then so mounted as
to be capable of some swivelling motion on or about its support f, so that its
discharge orifice can be directed to each or any of the said vessels to be filled as
will be readily understood without further illustration.
To provide against fraud malpractices and accidental waste of milk we provide
a check on the lock. This may consist of the arrangement shown in Figures 1, 2
and 3 wherein a stop is arranged to act upon the latch of the lock and its position
controlled by the milk vessel itself so that the cover C is always held locked and
cannot be opened even by its proper key until and unless the inilk vessel V is in
the proper position for filling, but when the vessel is in position its weight frees
the stop and lock and the cover can be opened by its key.
To the catch of lock L is applied a tail lever B: H is the vessel holder
hinged to the door frame c at hand having a weighted stop S which when vessel V
is not in position rests back against cover C below tail B which thus holds up
catch and the lock cannot be operated, but when the vessel V is hung on H its
weight removes S and the lock is freed.
The dotted lines in Figure 1 show the position of the parts when opened.
An alternative arrangement of checking device is shown in Figures 4, 5 and 6
wherein a catch is arranged to act-upon the cover C: in this case the milkman
carries the distributing funnel.
Figure 4 is a vertical section showing the parts locked the vessel not being in
position.
Figure 5 is a section showing vessels in position, and in dotted lines the inserted
funnel and change of position of parts.
Figure 6 is a sectional plan with funnel inserted, and
Figure 7 a perspective view of funnel.
A tube T is fitted in aperture a on which is centred a lever G having a
catch on its longer arm adapted to engage an eye c³ on cover C when the
vessel V is not in position; and a sloping tail g'.
The inner end of tube T is provided with a flap t hinged at t to a slotted
flange to upon and projecting above the tube T, and capable of vertical turning
about ; upon the hinge pin is an arm counterweighted at one end to keep the
flap normally closed as illustrated at Figure 4, and its other end t projects through
the slotted flange to towards the tail g of lever G and is forked so that it can pass
over the tail g₁ when operated as hereinafter set forth.
The vessel V has an aperture adapted to fit over the flapt and tube T and when
it is placed in position it rests upon the tail g' and against the forked end t³, and its
weight pressing down tail g raises catch gout of engagement with eye c³ of
cover C which can then be opened by its key; when the funnel is inserted it
raises the flap and the part 3 of arm t² is turned down out of engagement with
the vessel which then slips off the tail g' against the flange to thus liberating
lever G, so that when the funnel is withdrawn the cover C will be again locked by
the catch g and cannot be opened by its key.
When more than one delivery is to be made at one house any number of vessels

page_text: may be provided and attached one behind the other, and to prevent milk being
spilled in case the inner vessel is not in position we provide as follows: a second
vessel V is fixed by hooks K to the first vessel V and apertures for the passage of
the funnel F are cut in the juxtaposited sides of V, V.
The aperture on the first vessel V is protected by an inwardly opening hinged
flap & normally closed by its gravity so as to stop the passage of the funnel if Vi is
not in position. The flap & has a projection arranged as shown Figure 5 so that
the act of placing the second vessel V in position will open the said flap k so as to
allow the passage of the funnel F as illustrated in Figures 5 and 6, but the flap of
the outermost vessel is always closed and the further passage of the funnel
prevented.
The funnel F may conveniently be made of the form illustrated in Figure 7 closed
at its end and having a discharge aperture at f¹ and a hinged stop f* for determining
the distance of insertion for the first vessel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In appliances for delivering milk to houses the application of means such as
are herein described for maintaining the delivering aperture cover locked unless
and until the receiving vessel is in position and then utilizing the gravity of the
vessel itself when placed in position to automatically release a part and enable the
cover to be unlocked as and for the purposes set forth.
2. In an appliance for delivering milk to houses the combination with hinged
cover C and lock catch having tail B of hinged vessel holder H. and stop S adapted
to maintain the cover C permanently locked unless and until the vessel V is in
position for receiving the milk and then automatically releasing same all arranged
and operating substantially as set forth in reference to Figures 1, 2 and 3.
3. The locking and releasing devices applied to cover C as set forth in
reference to Figures 4, 5 and 6, consisting in the combination of cover C having
eye with catch lever G, hinged flap t, weighted arm & constructed as specified and
adapted to maintain cover C fast unless and until the receiving vessel is in position,
and then to automatically release said cover and allow insertion of milk funnel, but
to automatically relock same on withdrawal of funnel substantially as set forth.
4. The combination of hinged cover to aperture with locking device freed by
the action of the receiving vessel and adapted to be relocked by the action of
the inserted funnel, and the means described for preventing waste of milk in
case of more than one vessel being employed substantially as set forth and
illustrated.
5. The herein before described improved means and appliances for the delivery of
milk to houses in the manner set forth.
