PROVISIONAL SPECIFICATION.
Improvements in Centrifugal Apparatus for Butyrometers and other
Fat Testing Instruments and for the like purposes.
We, WILLIAM THOMAS WEBSTER, FR M S., of 252, Caledonian Road, in the
County of London, Analytical Chemist, and the DAIRY OUTFIT COMPANY, LIMITED,
of 251, Pentonville Road, King's Cross, in the County of London, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to produce centrifugal apparatus for butyro-
meters and other fat testing instruments and for like purposes which can be
placed in any convenient spot and there rotated without requiring to be fixed
thereto, and whereby also the sample or substance can be rapidly and effectively
subjected to the centrifugal process while retaining the necessary amount of heat
The centrifugal apparatus consists of a spindle or shaft having a handle or
holding device at one end and a base or foot at the other end and carrying a
bevel cog wheel mounted in suitable bearings on the spindle which wheel is
provided with a handle or like device for rotating it
This bevel cog wheel engages a smaller bevel cog wheel fixed to a sleeve rotat-
ing freely on the said spindle or shaft and to the said sleeve a number of radial
arms are fixed in a position slightly inclined downwards towards the outer ends.
These radial arms are fitted with spring clips or the like to receive tubes fitted
with removeable enda and made of cardboard or other heat non-conducting
material.
Into these tubes the milk-sample or other testing tubes are placed, the ends are
closed, the base or foot of the spindle of the centrifugal apparatus is then placed
on any convenient spot and the whirling of the apparatus is effected by rotating
the hand bevel wheel

page_text: formed to be particularly described and ascertained in and by the following state-
ment:-
The object of this invention is to provide a centrifugal apparatus for butyro-
meters and other fat testing instruments and for the like purposes which can
be placed in any convenient apot and there rotated without requiring to be fixed
thereto and whereby also the sample of substance can be rapidly and efficiently
subjected to the centrifugal process while retaining the necessary amount of heat
The accompanying drawing shows a partly sectional elevation of the centrifugal
apparatus forming the subject of this invention, A is a spindle or shaft having
a handle or holding device A¹ at one end and a base or foot A³ at the other end.
The handle A is affixed to a frame B to which the spindle A is secured by
means of the set screw b. To the frame B 18 secured a transverse pin b¹ one end
of which projects beyond the frame and has rotatably mounted on it a bevel cog
wheel C having a crank handle D affixed thereto. This wheel engages with a
small bevel cog wheel E fixed to a sleeve F rotating freely on the spindle or
shaft A, and to the said sleeve F a number of radial arms G are affixed in a
position slightly inclined downwards towards the outer ends. These radial arms G
are fitted with spring clips or the like g to receive tubes H fitted with remove-
able ends and made of, or lined with, cardboard or other heat non-conducting
material
Into these tubes the milk-sample or other testing tubes J are placed, the
ends are closed, the base or foot A of the spindle A of the centrifugal appa-
ratus is then placed on any convenient spot and the whirling of the apparatus is
effected by rotating the hand bevel wheel C.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same 18 to be performed we declare that what
we claim is:--
Centrifugal apparatus for butyrometeis and other fat testing instruments and
for the like purpose, comprising a non-rotatable shaft having a holding device
and a foot or base, a rotatable sleeve on said shaft with downwardly inclined
radial arms affixed thereto, a bevel wheel on said sleeve, a second bevel wheel
geaung with the first and carried by the frame of the apparatus and fitted with
a crank handle or other means for rotating it substantially as described.
