PROVISIONAL SPECIFICATION.
Improved Devices for Cleaning Churns, Milk Cans, and similar
Receptacles.
I, CHARLES HEDGES of Spa House, Box, in the County of Wiltshire Gentleman
do hereby declare the nature of this invention to be as follows:-
This invention relates to the cleaning of churns, milk cans and similar receptacles
whose interior is of other than cylindrical nature and of wider diameter in places
than the open orifice through which the cleaner is to be introduced, and the
purpose of the improvements is to provide for the more efficient cleaning of the
interior surface by means of a revolving brush or system of brushes, or of a
stationary brush or system where the vessel revolves.
The brush system comprises a series of bars of the general shape of the inside of
the vessel cut upon a plane parallel to the axis or some plane near thereto so that
the bars may extend from the base of the vessel to the mouth or neck.
Inasmuch as in churns and the like the base is of greater diameter than the neck,
the bars which are provided with brushing or equivalent cleaning surfaces are
mounted so that they may be contracted together for insertion into the vessel and
afterwards expanded within the latter so as to come in contact with the walls
throughout their whole height. This may be effected by connecting the bars at
one end to a rigid disk or rigid arms and at the other to hinged or pivoted arms.
A central shaft carries the aforesaid disk or arms sliding thereon and the latter
hinged arms hinged to it or to a disk thereon without sliding. Movement of the
sliding disk or arms will draw the bars so that the hinged arms revolve on their
pivotal centres thus drawing the bars towards the shaft for insertion or withdrawal
from the vessel, or pushing them from the shaft and so extending the diameter of
their action when within the vessel. There may be brushes on the hinged arms or
on the disks and the device described may be used in conjunction with other
brushes adapted to clean the exterior of the vessel at the same time, the brushes
then revolving in opposite directions where the outside brushes are rotary
brushes.

COMPLETE SPECIFICATION.
Improved Devices for Cleaning Churns, Milk Cans, and similar
Receptacles.
I CHARLES HEDGES of Spa House, Box, in the County of Wiltshire, Gentleman,
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 relates to the cleaning of churns, milk cans, and similar receptacles
whose interior is of other than cylindrical nature and of wider diameter in places
than the open orifice through which the cleaner is to be introduced, and the
purpose of the improvements is to provide for the more efficient cleaning of the
interior surface by means of a revolving brush or system of brushes, or of a
stationary brush or system where the vessel revolves.

page_text: The brush system comprises a series of bars of the general shape of the inside of
the vessel cut upon a plane parallel to the axis or some plane near thereto so that
the bars may extend from the base of the vessel to the mouth or neck.
Inasmuch as in churns and the like, the base is of greater diameter than the neck
the bars which are provided with brushing or equivalent cleaning surfaces are
mounted so that they may be contracted together for insertion into the vessel and
afterwards expanded within the latter so as to come in contact with the walls
throughout their whole height.
This may be effected by connecting the bars at one end to a rigid disk or rigid
arms and at the other to hinged or pivoted arms. A central shaft carries the
aforesaid disk or arms sliding thereon and the latter hinged arms hinged to it or to
a disk thereon without sliding. Movement of the sliding disk or arms will draw the
bars so that the hinged arms revolve on their pivotal centres thus drawing the bars
towards the shaft for insertion or withdrawal from the vessel, or pushing them
from the shaft and so extending the diameter of their action when within the vessel.
There may be brushes on the hinged arms or on the disks and the device described
may be used in conjunction with other brushes adapted to clean the exterior of the
vessel at the same time, the brushes then revolving in opposite directions where the
outside brushes are rotary brushes.
The annexed drawing will illustrate a convenient mode of performing the inven-
tion. Fig. 1 being a churn in section, with the improved brush or devices therein
shown expanded against the sides. X is the churn, A. the centre shaft, bar, or
member of the brush device which has expansible side bars or arms B and C
attached to it at the top by a cross bar H having forked ends working on and
controlled by pins L fitted in the side bars B and C as shown in Fig. I and in
enlarged plan in Fig. 2. Said side bars are kept in an extended position by the
springs D sprung between them and the centre bar as shown; to said side bars are
hinged or pivoted at K and J two bottom bars E and F which are slotted and work
on a pin or guide M placed on the bottom of the centre bar A. The articulations
of the brush device are such that on pulling out or upwards the handle N the
centre bar A is drawn upwards and the spring is drawn inwards together with the
side and bottom bars and the whole can be removed through the top of the churn.
The gearing with handle for working the brush may be of any convenient kind
and supported on prongs or limbs O as shown.
Several of such brush devices can be worked off one shaft with appropriate
gearing and in such a way that while the insides of contiguous churns are being
cleaned, their outsides may be also cleaned by brush devices of similar construction
but arranged the other way up.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
The improved devices fitted with brushes arranged and operated substantially as
illustrated and described for the purposes of cleaning milk cans and receptacles of a
similar nature.
