Improvements in or relating to Ascertaining the Weight of
Animals.
I, JON KJELLESTRÖM, Lieutenant, of Karlsborg, in the Kingdom of Sweden,
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 :-
According to the experience of the inventor, cattle, having the compass or
circumference over the breast immediately behind the shoulders diminished by 3rd.
of the difference between this compass and the length (C CL) alike (the
3
length preferably taken from the anterior upper point of the shoulder-blade to the
root of the tail), have the same weight (slaughter weight as well as living
weight), wherefrom it results that like sums of the compass and the half length

and length (C-C-L),

The inventor has likewise found that hogs, the compass of which diminished by
half the difference between compass
the length
preferably taken from the vertex of the head-in the middle between the ears-to
the root of the tail, is alike, have the same weight (slaughter weight as well as
living weight).
The measure which for cattle contains its compass diminished with the third part
of the difference between this compass and the length of its compass added to
the half length and for a hog its compass diminished with half the difference
"of the
between its compass and length, is hereinafter called the "weight measure
animal.
Two animals for which these measurements are equal have nevertheless seldom
the same compass and length, but-as already stated-when their weight measures
are equal, the weights (slaughter weight as well as living weight) are however the
same. When now for instance the weight-measure is 275 cm. for an animal, the
compass of which is 215 cm. and its length 120 cm. and the same is the case for an
animal with a compass of 205 cm. and a length of a 140 cm. and it being known
by experience, that the one as well as the other comprises 402 kg. living weight or
201 kg. slaughter weight, then those weights can consequently be indicated by the
weight-measures.
Upon these facts the present invention is based and consists of a tape or
equivalent measure (see the accompanying drawing) preferably 3.5 metres in length
and 1 centimetre wide, divided in weight measures calculated according to either of
the above formulæ and provided, according to the ascertained facts, with the
kilogram figures on the weight (living or slaughter weight) corresponding with the
weight measures. Thus the tape contains between 62-8 cm. and 157 cm. the weight
measures provided with their kilogram figures for the weight of hogs and for that
between 200 cm.
of cattle, when the division is based upon the formula C + 2'
and 351 cm.
L
When using the tape for ascertaining the weight of hogs, this division is made so
that, as indicated by the formula, the compass and the length are respectively
measured from the point of zero on the tape, and the portion of the tape indicating

in this folding.

When using this tape on cattle, the length of the animal is taken with the tape
for determining the quantities in the formula C + 2, referring to cattle, and this
portion of the tape is folded in the middle, the middle point being retained with the
thumb and the fore finger of the one hand and counted from this point, the compass
of the animal is now taken with the remaining portion of the tape, whereafter the
weight is immediately read at the last point obtained.

If the formula C
is taken as basis for the division of the cattle
weight-measures on the tape the compass and the length is taken from the point of
zero on the same, whereupon the portion of the tape indicating the difference
between these measures, is folded in three equal parts and the weight is read in the
extreme folding.
In the preceding formulæ L can in general be considered equal to the length of
the trunk and C equal to the compass of the breast immediately behind the
shoulders. At each line of division are three fingers. These are printed upon the
tape preferably in different. colours and the lower, middle or higher value is taken
according as the animal is of an average or other condition. If desired the back of
the tape can be divided in metres and parts thereof, but this is not necessary for the
above use of the tape, as the reading takes place on the front-face of the tape after
measuring directly upon the animal.
Instead of the measurements being indicated and taken according to the
"centimetre-gramme" system they may be indicated and taken according to the
"foot pound" or any other system.

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 I
claim is ;-
1. Ascertaining the weight of animals substantially as described.
2. A tape for or equivalent measuring device for determining the living or the
slaughter weight of cattle and hogs based upon the formulæ C

these weight measures so that when measuring the compass and length of cattle and
hogs by means of this device and treating the corresponding lengths of the device
in accordance with these formulæ the living or slaughter weight of the measured

3. A weight and dimension measuring tape or device substantially as described
and illustrated in the accompanying drawing.
