It is, of course, very undesirable to make the

strap so light that it will readily break, as this
beneath a cow.
One feature of this invention is that the milker OI means that the strap must be continually re
placed. Moreover, if '-the strap is made light
support includes a connection arranged to with
enough to break at the desired strain when it
stand the normal milking strains but to separate
when the strain on the connection exceeds a pre
determined force, to prevent injury to the cow in
the event it catches a foot in the supporting
means, or in the event of any other abnormal
strains; another feature of this invention is that
although it requires a substantial ‘force to sepa
rate the connection, it can be remade easily; and
still another feature of this invention is that the
release means comprising a preferred embodi
ment of this invention is simple and rugged, well
adapted to service in a dairy barn.‘ Other fea
tures and advantages of this invention will be
apparent from the following speci?cation and 20
the drawings, in which:

is new, deterioration due to age, sweat and the
like will cause it to break under normal milking
strains, since a completely ?lled suspended‘
milker weighs in the neighborhood of 50 pounds
and this force is increased by dynamic strains
due to movement.
I have obviated these di?iculties by devising re
lease means which will maintain the milker in
proper position and withstand all normal milk
ing strains but which will cause a connection of
the supporting apparatus to separate when a pre
determined strain is exceeded. Moreover, my re
lease means is so constructed that it does not
deteriorate or change with age, and so that a
connection broken by abnormal strains can be
quite easily remade.
In the particular. embodiment of my invention
