Improvements in Means for Suspending Mechanical Milking
Apparatus from the Cow.
I, CARL GUSTAF PATRIK DE LAVAL of 16A Handtverkaregatan, Stockholm,
Sweden, Doctor of Philosophy and 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 improved device for suspending a mechanical milking-
apparatus. from the cow in such a manner that, the apparatus, with a single grasp is
brought into its, right position. for use.. For this purpose a saddle girth or belt
is arranged around the waist of the cow, and to this girth a suspensory attachment
having a horizontal guide of some suitable form and nature is attached in a suitable
manner, upon which guide the milking apparatus is hung, so that it comes in its
proper, position. This guide forms a path, upon which the milking-apparatus can
slide and it can be arranged in different ways, of which some will be named
hereinafter.
In the accompanying drawings.
Figs. 1 and 2 show in part sectional side view and in part sectional plan,
respectively, a construction according to my invention.
Fig. 3 shows a milking-apparatus, as suspended on a cow.
Similar letters of reference indicate corresponding parts.
The arrangement shown on the drawing consists in a tube or sleeve a, through
which a cord.b or the like is passed in such a way that the tube can be moved upon
the cord. The ends of the cord are provided with means, for instance buckles c,
for attaching it to a saddle girth, which is passed around the waist of the cow.
The tube. a, cord. b, and buckles c form what may be termed the suspensory
attachment.
The tube or sleeve a is straight at its middle part and supports a rod e, which
extends laterally from the tube and runs parallel with it. The milking apparatus
is provided with a sleeve, which is inserted on said rod e, and the free end of
which extends forward beyond the straight, middle portion of the tube, which has
end portions a', a', bent according to the contour of the belly of the cow.
This said sleeve may properly, as shown in the drawing, be provided with an
to on
enlarged mouthpiece
rod e.
In order to prevent the apparatus suspended in this manner from turning the
tube a the apparatus being suspended laterally to the middle part of the tube,
the ends a', a', of the tube a are bent forward in such a way that the centre line of
said ends of the tube lies in a vertical plane through the centre-line of the rod.
Fig. 2 sbows this clearly.
The cord b is passed loosely through the tube a thus enabling the tube to be
moved on the cord. When using this suspensory arrangement, the saddle girth
fixed at c c is applied to the cow and then the milking apparatus is supported on
the rod e by means of the sleeve f.
As modifications of the invention may be mentioned that the milking apparatus
may be provided with a rod or pin formed like e and the guide or path, fitted apon
the tube, consist of a sleeve f. Furthermore the guide or path inay be arranged
either above or beneath the tube; and in these cases the ends of the tube do not-
need to be bent forward as shown at a' in the drawing and it causes no trouble evca
if the tube turns a little by the insertion of the apparatus.

page_text: When the guide or path consists of a rod e said rod may be attached to the tube
at more than one place. The sleeve ƒ must be slit open for enabling the insertion
upon the rod.
Instead of the tube a, a rod which by means of hooks or otherwise is attached to
the saddle girth, may also be used.
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. In means for suspending milking apparatus the combination of a suspensory
attachment to be applied to a girth around the body of the cow and consisting of a
tube, a guide-rod fixed to and extending laterally from said tube, and a sleeve
attached on the frame of the milking apparatus and adapted to be received on said
guide-rod, substantially as set forth.
2. In means for suspending milking apparatus the combination of a suspensory
attachment to be applied to a girth around the body of the cow and consisting of a
tube, being straight at its middle part, a guide-rod fixed to and extending laterally
from said tube and running parallel with its middle part, and a sleeve attached on
the frame of the milking apparatus and adapted to be received on said guide-rod,
substantially as set forth.
3. In means for suspending milking apparatus on the cow, the combination of
the suspensory attachment to be applied to a girth around the waist of the cow
and consisting of a tube, and a cord passing through the tube, a rod fixed to and
extending parallel with said tube and with its free end reaching forward beyond
the middle part of said tube, and a sleeve attached on the frame of the milking
apparatus and adapted to be received on said guide-rod, substantially as
set forth.
4. In means for suspending milking apparatus on the cow, the combination of
a tube, the end parts of which are bent according to the belly of the cow, a cord
passing through the tube adapted to be attached to a girth applied around the
waist of the cow, and a horizontal rod, extending laterally from said tube and
running parallel with it, the ends of the said tube being bent forward so that their
centre-line falls in a vertical plane through the centre line of the rod, substantially
as set forth.
