PROVISIONAL SPECIFICATION.
Improvements in Shafts for Road Vehioles.
We EDRICA DE LA POLE of Shute House, Devon, Lady and JOHN HENRY
BOLL of Yeovil, Somerset, Coach Builder do hereby declare the nature of this
invention to be as follows :-
1
Two pairs of shafts No. 1 & 2 on drawing are fitted to a pair of short shafts No. 3
and a cross bar No. 4, being well secured with plates of spring steel at points a, b, c & d.
The pair of shafts No. 3 are fitted to any two wheel carriage in the usual way (with
a shaft spring at back preferable) but made movable, so that a pair of single shafts
may take their place if required; thus enabling a single, or a pair of horses being
driven in a two wheel carriage, and with safety, with 2 sets of ordinary single
harness, requiring a pair of double reins only.

COMPLETE SPECIFICATION.
Improvements in Shafts for Road Vehicles.
We EDRICA DE LA POLE of Shute House, Devon, Lady, and JOHN HENRY
BOLL of Yeovil, Somerset Coach Builder do hereby declare the nature of this
invention and what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Two pairs of shafts No. 1 and 2 on drawing “left with the Provisional Specifica-
tion" made of wood of a springy nature such as lancewood are fitted to a pair of
short shafts No. 3 and a cross bar No. 4, a piece of wood is fitted between the
shafts No. 2, from the cross bar No. 4 up to points b. to keep them apart; plates
not less than 18 in. long run across the shafts No. 2 from points 6. to (one on
top and one on bottom) both bolted together, thus firmly securing the four shafts
at points b. b. Points c and d are also secured with plates. Shafts No. 1 are held
firmly against short shafts No. 3 at points a by means of a coupling-plate and strap-
bolt, top and bottom; made of spring steel and firmly fixed to shafts No. 3 with
screws and a shaft clip at point a (or shafts No. 1 and 3 may be bent and made
of one piece of wood, in this case a short bar is fitted between shafts 1 and 2, at
points a and b). The short shafts No. 3 are fitted to any two wheel carriage in
the usual way (with shaft spring at back preferable) but made movable so that a
pair of single shafts may take their place if required. The cross bar No. 4, (in
Atting up the shafts) goes under the foot board as far back as possible and back
part of shafts No. I a little in front of the dash, thus the back part of shafts No. 1
will support shafts No. 2 in the same way as a splinter bar supports a pole in a
four wheel carriage. Both horses being between the shafts they are always kopt
in their proper places. Both pairs of shafts play freely, independent of each other,
allowing a pair of horses with totally different action to be driven together, without
producing knee action or making the cart uncomfortable, in fact if one horse
canters whilst the other is trotting the body of cart remains comparatively steady
and very little inconvenience is felt by the occupants.
It is far easier than a pole and curricle for a two wheel and much safer; two
sets of ordinary single harness with a pair of double reins only are required, instead
of a special set of harness.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The method herein set forth of driving a pair of horses in a two wheel
carriage by means of a double pair of shafts taking the place of single shafts, but
being able to use either.
2. The use of a double pair of shafts made of wood of a spring nature being
much safer and easier for the occupants than a pole.
3. The advantage of being able to use two sets of ordinary single harness for
driving a pair in a two-wheel.
