PROVISIONAL SPECIFICATION.
Improvements connected with Shaft Attachments for Road
Vehicles.
I. ARTHUR BARNWELL, of 48 James Street, Rugby, Warwickshire, Coach
Builder, do hereby declare the nature of this invention to be as follows:-
This invention has for object, to reduce or obviate a rattling-noise between the
shaft attachments of road vehicles, also to give a cushion like pull upon the vehicle
to relieve the strain upon the horse, as between the collar and the vehicle.
For the purpose of my invention, I employ india rubber tubing in the eye of the
connection iron and the barrel to which the shaft is attached, and in combination
therewith, I employ a pad of india rubber between said iron and the shaft bar.
To carry my invention into practice, I enclose the bolt between the two ears of
the connecting iron with a length of india rubber tubing specially made to fit, and I
surround said india rubber by a barrel, the tangs of which are affixed to the shaft.
In conjunction with the foregoing, I slot the back plate of the connection and fit
the lip of an india rubber pad therein, said lip projecting slightly through for the
back surface of shaft barrel to impinge against should the eye tubing become worn
from the constant action of the shaft in being subject to extra wear from the pulling
and backing of the vehicle. This lip is in a piece with a pad fitted between the
connection and the shaft bar.
The arrangement of the eye tubing is applicable whether the shaft be attached
to the front of or under the shaft bar and the connection can be fixed in place by
bolts or by clips.

COMPLETE SPECIFICATION.
Improvements connected with Shaft Attachments for Road
Vehicles.
I, ARTHUR BARNWELL, of 48 James Street, Rugby, Warwickshire, Coach
Builder, 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 has for object, to reduce or obviate a rattling noise between the
shaft attachments of road vehicles, also to give a cushion like pull upon the vehicle
to relieve the strain upon the horse, as between the collar and the vehicle.
For the purpose of my invention, I employ india rubber tubing in the eye of the
connection iron and the barrel to which the shaft is attached, and in combination
therewith, I employ a pad of india rubber between said iron and the shaft bar.
To carry my invention into practice, I enclose the bolt between the two ears of
the connecting iron with a length of india rubber tubing specially made to fit, and I
surround said india rubber by a barrel, the tangs of which are affixed to the shaft.
In conjunction with the foregoing, I slot the back plate of the connection and fit
the lip of an india rubber pad therein, said lip projecting slightly through for the
back surface of shaft barrel to impinge against should the eye tubing become worn
from the constant action of the shaft in being subject to extra wear from the pulling

page_text: and backing of the vehicle. This lip is in a piece with a pad fitted between the
connection and the shaft bar.
The arrangement of the eye tubing is applicable whether the shaft be attached
to the front of or under the shaft bar, and the connection can be fixed in place by
bolts, or by clips.
My invention will be understood by the annexed drawings, in which I show
several forms of shaft attachment with rubber compound cushions.
Figure 1 represents a side view of a dog cart with shafts outside the body, and
fitted by scroll irons and bracket plates respectively.
Figure 2 is a back view of a cart showing four different arrangements of con-
necting, one A being from the bottom back rail B, one C from body side corner
post D, and two by back cross spring or curved bar E, one of these being an eye
coupling F, and one with socket G bolted direct to end of spring E.
Figure 3 shows a back attachment of shaft and composed of a combined strap H
with lips I, I, barrel J, and bolt K to a tang L capable of being welded to a scroll
iron of any shape, the strap H and the barrel J being provided with rubber
tubing M, N, as a liner, the tubing M having a depending check P to bear upon
the barrel J to prevent the strap H jumping should the bolt K become worn,
whereby I preserve the cushioning action of the shaft socket rubber M which the
shaft fits tightly but with an amount of play by the compression of the rubber due
to the position of the load, and the oscillation given by the horse, that part of the
shaft Q being of oval formation to fit the oval form of rubber and strap H but
which shape would vary to suit taste, or fancy.
Figure 4 represents a front shaft clip R bolted down upon an eye plate S, said
plate having a hole, through which a depending cheek P of the rubber M as a flat
cushion, which either projects slightly above the surface of the plate S, as at
Figure 5, or is spread over the surface of the plate, as at Figure 6, to bear in
contact with the shaft Q when clamped home, this forming the fulcrum on which
the shaft can oscillate as well as the purchase for draught by the attachment of the
scroll iron T to the body.
Figure 7 shows a single cushion strap with lug U for direct attachment to body
or spring, as at G (Figure 2) by the inserted bolt V put in place before the rubber
cushion M is pushed in.
Figure 8 illustrates a barrel for similar direct connection to body, or to spring,
as at A, F, (Figure 2) the hole in the rubber being for the bolt K, as at Figure 3,
for rear end of shaft, and I employ a square socket, as at Figure 9, with a similar
arrangement of fastening direct, as at Figure 7, or by the strap and lip appliances
Figure 10, and as seen in the perspective view, Figure 11.
If desired, the barrel bolt K may be part of the scroll iron, or other form, as at
Figure 12, for attachment, as at C, Figure 2, to the cart, and such means of
attachment may have any desired number of fangs W, as at Figure 13, to suit the
position.
I am aware that rings, blocks, and different shaped pieces of rubber, as cushions,
have been applied to cart shaft attachments before the date of my present
application for Patent, but in no instance has a collar kind of cushion been made to
be encircled by a strap, and provided with a depending lip to abut upon the metal
barrel containing a rubber tube, as at Figure 3, within which, a bolt is fitted from
one part of the connection to another part thereof.
Neither has a flat rubber body with a depending lip been employed in a bracket
for shaft front attachment, said lip to bear upon a barrel containing a rubber tube
for a bolt, as at Figure 4.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. The employment of moulded rubber cushions with depending lips in clips in
conjunction with rubber cushions in the barrels of single eves for attachment by

page_text: scroll irons to the rear of shafts and cart body respectively, as shown on the annexed
drawings, and as described.
2. The employment of moulded rubber with depending lips in bracket plates in
conjunction with rubber cushions in barrel of single eyes for attachment to fore ends
of shafts and cart body respectively, as shown on the annexed drawings, and as
described.
3. The employment of moulded rubber with overlap ends, and acting as liners
for direct touch of cart shafts, as and for the purposes described, and as shown on
the drawings.
