PROVISIONAL SPECIFICATION.
Improvements in Milk-testers.
I, EDWARD ASHTON LISTER, of Victoria Iron Works, Dursley, in the County
of Gloucester, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to milk-testing machines of the kind in which a series of
test bottles are connected to a revolving wheel or disc, as for instance in what is
known as the "Babcock" tester.
The object of my invention is to provide improved means for carrying the test
bottles, so that they can be readily introduced into the machine, and so that they
are freely exposed to the action of the external heat which is usually applied
through the medium of hot water.
According to my invention I carry the test bottles in wire cages or carriers, each
carrier advantageously having an eye to receive the neck or contracted portion of
a test bottle and a base to support the bottle when in an upright position and to
resist the centrifugal action when in a horizontal position.
The said cages or carriers are advantageously formed with hooks by means of
which they may be connected with the revolving disc, but they may be connected
therewith by any other suitable means.

Improvements in Milk-testers.
I, EDWARD ASHTON LISTER, of Victoria Iron Works, Dursley, in the County
of Gloucester, 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 :-
My invention relates to machines for testing milk, cream or the like of the kind
in which a series of test bottles are connected to a revolving wheel or disc, as for
instance in what is known as the "Babcock" tester.
The object of my invention is to provide improved means for carrying the test
bottles, so that they can be readily introduced into the machine, and so that they
are freely exposed to the action of the external heat which is usually applied
through the medium of hot water.
According to my invention I carry the test bottles in wire-cages or carriers, each
carrier advantageously having an eye to receive the neck or contracted portion of
a test bottle and a base to support the bottle when in an upright position and to
resist the centrifugal action when in a horizontal position.
The said cages or carriers (which may be single or duplex) are advantageously
formed with hooks by means of which they can be connected with the revolving
disc, but they may be connected therewith by any other suitable means.

page_text: To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a perspective view of a single bottle-carrier for a milk or cream
testing machine constructed according to my invention; and,
Figure 2 is a perspective view of a duplex carrier, that is to say, a carrier
adapted to hold two bottles.
с
a is the eye of the carrier, 6 is the base or support, and c is the stem which at its
upper end is provided with a hook d as shewn in Figure 1 (or otherwise formed)
to enable it to be connected to the disc of the milk or cream testing machine.
The carrier shewn in Figure 2 is of similar construction to that shewn in
Figure 1 except that it is. provided with two eyes a and with two bases or
supports b. This holder instead of being provided with a hook as in Figure 1 is
represented as provided with a pine which is carried in suitable bearings in the
carrier-disc.
In practice I make my carriers of wire bent to the desired form. The carrier
shewn in Figure 1 is composed of a single piece of wire whilst that shewn in
Figure 2 is made of two pieces. It is to be understood, however, that the carrier
may be made in any other suitable manner.
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 :-
1. A cage or carrier for holding test bottles for testing milk, cream or the like,
the said carrier being made of wire and having an eye to receive the neck or
contracted portion of the bottle and a base or support for the bulb of such bottles,
substantially as described.
2. The manufacture and use of carriers for holding test bottles for milk or
cream-testing machines substantially as hereinbefore described and illustrated in
the accompanying drawing.
