Animals.
:
We, LOUIS ADRIAAN VAN DALSUM, Merchant, and JOHANNES GYSBERTUS
SLUYTER, Manufacturer, both of 138 Botersloot Rotterdam, Holland, do hereby
declare the nature of this invention to be as follows:-
any
kind
This invention relates to the haulage of vehicles by draught animals of
and its purpose is to protect the draught animal or animals from the effect of the
jolting of the vehicle and in general to render the drawing of the vehicle more
even and the pushing of the animal against its collar more uniform.
The improvements consist in forming the whiffle-bar to which the traces are
attached, of a flat spring of suitable constitution curved in the usual way, the
centre of the curve being presented outward, that is to say towards the draught
animal, in combination with a cross bar in the same horizontal plane as the spring
and adapted to form a stop for the latter when the tension of haulage is sufficient
to draw the spring into a straight line or nearly so, whereby the spring is drawn
against the said cross bar.
The spring is attached at its centre to the vehicle or any part thereof and the
traces are connected to its ends. The cross bar is fixed at the centre of the curve
of the spring and extends at each end to a suitable distance in the plane of flexure
of the spring.
Dated this 24th day of April 1893.

LOUIS ADRIAAN VAN DALSUM and JOHANNES GŸSBERTUS SLUYTER, both
at Rotterdam, Gedempte Botersloot No. 138, Irondealers, 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 whiffle bars for the haulage of vehicles by dranght
animals of any kind, and its purpose is to protect the draught animal or animals
from the effect of the jolting of the vehicle and in general to render the drawing of
the vehicle more even and the pushing of the animal against its collar more
uniform.
Reference being made to the annexed drawing,
Fig. 1 is a plan view, and Fig. 2 an elevation from the back or vehicle, of a
whiffle bar constructed according to this invention.
The improvements consist in forming the whiffle bar B to which the traces are
attached, of a flat spring of suitable constitution, curved as is usual with springs
which are made up of a bundle of flat plates, the centre of the curve being
presented outward, that is to say towards the draught animal, in combination with
a rigid and inflexible cross bar E in the same horizontal plane as the spring
connected to it at the centre and extending so as to form a stop for the latter
TDOI

nearly so, whereby the spring is drawn against the said cross bar.
The spring is provided at its centre with an eye. A for securing it to the vehicle
or any part thereof, and the traces are connected to its ends, for which it is
provided with eyes C. C. The cross har E is fixed at the centre of the curve of
the spring and extends at each end to a suitable distance in the plane of flexure of
the spring to form with its ends F F abutments for the cushion blocks D D fixed
on the spring.
: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
-claim is :-
A whiffle bar consisting of a curved flat spring in combination with a centrally
placed eye directed towards the centre of the curve and an inflexible cross bar
attached at the centre of the outside of the curved spring extending in the plane
of flexure of the spring and adapted to serve for abutments for limiting the flexure
thereof substantially as set forth.
