PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Sterilizing Milk and other Liquids.
We, ARTHUR SAXBY BARHAM, Managing Director of The Dairy Supply Company,
Limited, of 28 Museum Street, and LOUIS DE WYTTENBACH, Merchant, of
7 Bloomsbury Square, both in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in the apparatus described in our
Specification No. 13802 of 1896.
In place of the movable lid bearing on the collars by which the bottles are
closed we now employ simply a pair of transverse bars or an open frame actuated
by a screw in a similar manner to that employed for the lid. We now also close
the apparatus by a steam tight cover which fits onto the top and is secured by
clamps or otherwise. We also preferably close the collars on the top in lieu of
joining the flange and guide by stays, so that they assume the form of inverted
annular troughs.
In order to readily empty the vessel in which the milk or other liquid is sterilized
or heated in bulk we make a hole in the lid in which is secured a pipe passing
down nearly to the bottom of the vessel. This pipe is provided with a cock, above
the lid, and is curved downwards. When the heating or sterilizing has been
completed the cock is opened and the pressuro inside the vessel forces the liquid
out through the pipe.
The pipe is then disconnected and lifted out and a funnel is attached in its place
through which the vessel is refilled.

Limited, of 28 Museum Street, and LOUIS DE WYTTENBACH, Merchant, of

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:-

Specification No. 13802 of 1896.
In place of the moveable lid bearing on the collars by which the bottles are
closed we now employ simply a pair of transverse bars or an open frame actuated
by a screw in a similar manner to that employed for the lid. We now also close the
apparatus by a steam tight cover which fits onto the top and is secured by clamps
or otherwise. We also preferably close the collars on the top in lieu of joining
the flange and guide by stays, so that they assume the form of inverted annular
troughs.
In order to readily empty the vessel in which the milk or other liquid is sterilized
or heated in bulk we make a hole in the lid in which is secured a pipe passing
down nearly to the bottom of the vessel. This pipe is provided with a cock, above
the lid, and is curved downwards. When the heating or sterilizing has been
completed the cock is opened and the pressure inside the vessel forces the liquid
out through the pipe.
The pipe is then disconnected and lifted out and a funnel is attached in its place
through which the voggol is refilled
Figure 1 is a plan, Figure 2 a vertical section, and Figure 3 a horizontal section
along the lines I-II. and III.-IV. in Figure 2. Figure 4 is a plan view of the
cross bars for depressing the collars.
Figures 5 and 6 are vertical and horizontal sections of the vessel used for
sterilizing liquids in bulk, Figure 5 showing the syphon used for emptying the
vessel.
A is the outer vessel closed with a lid A¹ which has a double flange A2 A²
around its circumference in which a packing of felt or similar material may be
placed so that when the lid is held down by the clamping screws A' the vessel may
be closed air-tight. The lid is provided with holes a through which thermometers
may be inserted and with a safety valve a².
The means for supporting the bottles or vessels containing the liquid to be
sterilized, for closing the stoppers of the bottles and for introducing steam into the
vessel A are the same as those described in the Specification No. 13802 of 1896
except that we replace the moveable lid therein described by a pair of transverse
bars or an open frame b and that we form the annular collars O in the shape of
inverted troughs as shown in Figure 2.
In order the inore quickly to fill and empty the vessel S for sterilizing liquid in
bulk we provide a hole s in the lid A. (closed by a screw cap when not in use)
through which a funnel for filling or a syphon S¹ for emptying may be inserted as
shown in Figure 5. When the sterilization is complete the cock 8¹ is opened and
the pressure of the steam in the vessel A drives the liquid from the vessel S through
the syphon S¹ into a suitable receptacle. The syphon S' is then removed, a funnel
inserted and the vessel S refilled.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In apparatus such as is described in our specification before mentioned,
replacing the loosely fitting lid by an air tight lid and an open frame or transverse
arms substantially as described.
2. In apparatus such as is described in our specification before mentioned,
making the collars for closing the bottles of the form of an inverted trough.
3. In apparatus such as is described in our specification before mentioned, the
means for filling and emptying the vessel S substantially as described.
