PROVISIONAL SPECIFICATION.
New or Improved Machinery or Apparatus for Testing Milk and
Drying Butter.
I, SYDNEY CHEELD, of Waterside Iron Works, Chesham, in the County of
Buckingham, Engineer, do hereby declare the nature of the said invention to be
as follows:-
This invention relates to new or improved machinery or apparatus so arranged
and adapted that it can be employed either for the purpose of testing milk or for
extracting water or other liquids from butter by centrifugal action.
For this purpose I arrange a vertical spindle in a suitable framing or support
with strap or other gearing for imparting a suitable speed of rotation to the said
spindle. The upper end of the aforesaid spindle is adapted to receive and carry
round with it either the frame to contain the test tubes in the well known
centrifugal milk tester, or the cage of a centrifugal butter dryer, according as it is
required to use the machine as a milk tester or as a butter dryer, the aforesaid
test tube frame and the butter dryer cage being interchangeable on the spindle.
By these means the one machine or apparatus is made to serve at pleasure either
of the above-mentioned purposes by placing on the spindle the milk tester frame
when it is desired to use the machine as a milk tester, or the centrifugal cage when
it is desired to use the machine as a butter dryer.
The upper part of the apparatus is, or may be, surrounded with a casing or
vessel such as is usually employed round the milk testing frame or the butter
dryer cage when those parts are used in separate machines.
I do not confine myself to a vertically placed spindle, as the same may in some
cases be placed obliquely or horizontally, but so far as I am at present aware, the
best results are obtained with a vertical spindle.

COMPLETE SPECIFICATION.
New or Improved Machinery or Apparatus for Testing Milk and
Drying Butter.
I, SYDNEY CHEELD, of Waterside Iron Works, Chesham, in the County of
Buckingham, Engineer, do hereby declare the nature of the said 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 new or improved machinery or apparatus so arranged
and adapted that it can be employed either for the purpose of testing milk or for
extracting water or other liquids from butter by centrifugal action.
And in order that the said invention may be fully understood I will proceed to
describe the same with the aid of the accompanying drawings in which
Figure 1 is a sectional elevation of the apparatus arranged to act as a butter
drier.
Figure 2 is a sectional elevation of the same apparatus taken on a plane at right
angles to Figure 1, but arranged to act as a milk tester, and
Figure 3 is a plan of the base of the apparatus with the upper parts removed.

page_text: A is a vertical spindle mounted in bearings A' A² in a suitable framing or
support B and having a toothed bevil pinion C secured thereon and gearing with
a toothed bevil wheel D fixed on the counter-shaft G revolving in bearings G¹ G'
in the framing B. E is a spur pinion fixed on the end of the shaft G and gearing
with an internal spur wheel F turning on a pin fixed to the base or frame B. A
suitable speed of rotation can thus be imparted to the said spindle A by means of
the crank handle H secured to the wheel F. The upper end of the aforesaid
spindle A is adapted to receive and carry round with it either the frame 1 to
contain the test tubes J used in any suitable centrifugal milk-tester as shown in
Figure 2, or the cage K of a centrifugal butter dryer as shown in Figure 1,
according as it is required to use the machine as a milk tester, or as a butter
dryer; the aforesaid test tube frame I and the butter dryer cage K being
interchangeable on the spindle A, both being provided with a socket L provided
with a conical or pyramidal hole adapted to fit ou to the correspondingly shaped
upper end A3 of the spindle A.
By these means the one machine or apparatus is made to serve at pleasure either
of the above mentioned purposes by placing on the spindle A the milk tester
frame 1, when it is desired to use the machine as a milk tester, or the centrifugal
cage K when it is desired to use the machine as a butter dryer.
The upper part of the apparatus is or may be surrounded with a casing or
vessel M such as is usually employed round the milk testing frame or the butter
dryer cage when those parts are used in separate machines, and the said upper
part of the apparatus may also be covered with a lid or cover N. It is obvious
that the gearing for driving the machine may be modified in a variety of ways and
that instead of being actuated by hand, as shown in the drawings, it may be driven
by any other suitable means such as a strap and pulley for example. If desired
the machine may be provided with a brake of any suitable construction to assist in
stopping it quickly; for example a brake sheave P may be fixed on the shaft G
and a brake strap Q fixed at one end to a part R of the frame B may be carried
round the said sheave and fixed at the other end to a lever S. On raising this
lever the strap Q is tightened and the brake applied, and on lowering the said
lever the strap is relaxed and the brake taken off.
1 do not confice myself to a vertically placed spindle as the same may in some
cases be placed obliquely or horizontally but so far as 1 am at present aware the
best results are obtained with a vertical spindle.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what
claim is :-
First. Machinery or apparatus so arranged and adapted that it can be employed
either for testing milk or for extracting water or other liquids from butter by
centrifugal action, substantially as described.
Second. Machinery or apparatus for testing milk and extracting water or other
liquids from butter by centrifugal action which consists of a milk testing apparatus,
a butter drying apparatus and a revolving spindle, the said spindle being adapted
to support and carry round with it either the said milk testing apparatus or the
said butter drying apparatus both of which are adapted to fit interchangeably on
the said spindle, substantially as described with reference to the accompanying
drawings.
