Improvements in or applicable to Butter-drying Apparatus.
I, THOMAS BRADFORD, of High Holborn, London, Dairy Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to centrifugal butter-drying apparatus used for freeing
churned or granulated butter from adhering butter-milk and the like; and has, as its
main object, so to adapt such apparatus as to render it also applicable for washing the
butter and for brining it, so as to enable all such operations to be successively
accomplished in the same apparatus, whereby, unnecessary handling of the butter, in
removing it from the apparatus to a butter-worker, is avoided, and the operations are
expedited and rendered more cleanly.
To this end, I bridge the drying case, diametrically, by a bar or girder, which is
hinged, adjacent to the centre of its length, in such a manner, that, when its parts are
fully extended in line, the bar or girder will be rigid and will partake of the motion
imparted to the cage, the hinged connection of its parts also permitting of the same
being removed from the cage.
Midlength of the bar, it is formed as or is provided with a cup or liquid receptacle
adapted to support a cone and a stepped set of differentiating dispersing surfaces,
operating, while the cage is being driven at a sufficiently high speed, to deliver the
butter-washing-water or the brine, as the case inay be, (and which is admitted to the
cup from a convenient reservoir by a tap or the like) against the granulated butter
walled around the inner periphery of the cage, after being freed from the butter milk,
in a differentiated shower, the cone equally distributing the stream of water or brine
around it, and the successively lower steps of successively increasing diameter
dispersing and delivering the water or brine in a spray-like condition in successively
finer states of division.

I, THOMAS BRADFORD, of High Holborn, London, Dairy Engineer, 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 an improvement applicable to centrifugal butter-drying
apparatus of the character described in the Specification of Letters Patent No. 17971,
of 1895, granted to me, the improvement being designed to increase the utility of
such apparatus by providing means for washing and brining the butter in a more
effective manner, and whereby all required operations are caused to be successively

handling of the butter, in removing it from the apparatus to a butter-worker, is avoided,
and the operations are expedited and rendered more cleanly.
On the drawings:-
Fig. 1, represents, in elevation, partly in section, the centrifugal butter-dryer above
referred to, and also shows the improved spraying device applied thereto.
Fig. 2, represents the spraying device half in section and half in elevation. And
Fig. 3; represents the same in plan.
According to the invention, I apply to the rotary cage a, diametrically thereof,
a bar or girder b, which is formed in parts hinged together at c, in such a manner
that, when the device is applied to the cage-rim a', and its parts are fully extended
in line, its ends will be caused to rigidly engage with the cage-rim, so that it will
be caused to partake of the rotary motion of the cage, the hinged connection of
its parts also permitting of the same being caused to assume an angular relation
: so as to permit of the bar being readily removed from the cage.
Midlength of the bar, it is formed as or is provided with a cup or liquid
receptacle d, adapted to support a cone e, and a stepped set of differentiating
dispersing surfaces f, g, h, which, while the cage is being driven at a sufficiently
high speed by means of the handle i, serve to deliver the butter-washing-water, or
the brine, as the case may be, (and which is supplied to the cup b, from the
reservoir j,) against the granulated butter walled around the inner periphery of
the cage (in the operation of freeing it from the butter-milk) in a differentiated
shower, the cone e, equally distributing the stream of water or brine around it,
and the successively lower steps f, g, h, of successively increasing diameter,
dispersing and delivering the water or the brine in a spray-like condition in
⚫ successively finer states of division.
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 :-
The application to centrifugal butter-drying apparatus of the character herein-
before referred to, of a, spraying device constructed and adapted to operate in
- manner hereinbefore described.
