Improvements in Rest Bars for Road Vehicles.
I, JAKOB KRAUS, of Neuss a/Rh. in the Empire of Germany, 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 rest bar for road vehicles, and it is
particularly adapted for vehicles having two wheels and which may require the
horse to be unharnessed while the vehicle is still loaded, and it consists essentially
of the usual bar attached to the pole or to one of the shafts by any suitable form of
universal joint and of a sliding sleeve or socket mounted on one part and adapted to
engage with the other part and so make the joint rigid.
In the accompanying drawing which illustrates this invention:-
Figure 1 is a broken view in elevation-partly in section-showing the rest in
position for use.
Figure 2 is a similar view showing the rest in its raised position when not
in use.
Figures 3, 4 and 5 are broken views-partly in section-showing various
modifications of my invention, and
Figure 6 is a view in cross section on line A. B. Figure 5.
Throughout the views similar parts are marked with like letters of reference.
On to the top of the rest which may be of wood or other suitable material is
fixed a cap a carrying an extension a' which is preferably cylindrical in cross
section, but may be of any other desired shape. The free end of the extension a
carries a ring or loop adapted to engage with the ring or loop e carried by an
extension or projection d¹ on a plate d adapted to be attached to the pole or to one
of the shafts of the vehicle in the usual manner, the shape of the extension or
projection d in cross section coinciding with that of the extension a¹ of the cap a.
On the extension a' is mounted a sleeve or socket e free to slide thereon and
capable on being engaged with the extension or projection d¹ of making the joint of
the rest rigid as shown by Figure 1.
As a modification, the sleeve or socket e may be mounted to slide on the
extension or projection .
To keep the sleeve or socket e in engagement with the other part of the joint
either a wedge such as f (Figure 1) or a bayonet joint device consisting of a
feather a² on the extension a and a featherway el in the sleeve or socket e
(Figure 5) may be used, or the sleeve or socket e may be threaded internally to
screw on to the extension or projection d' which is threaded to receive it as shown
by Figure 3.
It will be understood that in vehicles having a pair of shafts one of these rests
may be applied to each of the shafts if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what. I
claim is :-
(1.) The improvements in rest bars for road vehicles substantially as herein-
before described and illustrated by the accompanying drawing.
(2.) In a rest bar for road vehicles, locking the joint by which the bar is
attached to its point of support to make the same rigid by means of a sliding sleeve
or socket substantially as set forth.

page_text: (3.) In a rest bar for road vehicles, the combination with the bar and its
attachment fittings, of an extension of the one part carrying a sliding sleeve or
socket, of a projection on the other part with which the sliding sleeve or socket can
engage,
and of any of the devices hereinbefore described and shown by the accom-
panying drawing or their equivalents for holding the sliding sleeve or socket in its
locking position, as set forth.
