We ALFRED GEORGE MARGETSON, of the Bristol Wagon Works, Bristol, Engineer
and WILLIAM STUDLEY HEK, of the same place, Foreman Wheelwright; do hereby
declare the nature of this invention to be as follows:-
The objects of our invention are to construct dog carts and other two-wheel
vehicles in such manner that the body can be readily adjusted or balanced in
accordance with the number of passengers carried, the distribution of the load or the
inclination of the road, and that a break or breaks can be applied in going down hill
without bringing the weight on to the horse's back as is the case with the breaks
usually employed on two-wheel vehicles.
For the purpose of enabling the body of the vehicle to be readily adjusted or
balanced we have below the body a frame which is connected to the shafts and is
made separately from the body. On each side of this frame is fixed a longitudinal
bar the front portion of which is toothed like a rack for a sufficient distance to
give the necessary travel to the body to and fro. To cach side of the body are
attached two brackets that carry small wheels which are grooved or flanged and run
on the longitudinal bars before described; the two front wheels are also toothed so as to
work into the racks or toothed portions of the said bars; these front wheels are
connected together by a horizontal spindle. Outside the body at one side is an
upright spindle fitted at top with a handle within reach of the driver. This spindle
has a worn at its lower end gearing with a wheel on the horizontal spindle. By
turning the handle in the one direction or the other the body can be moved back-
ward or forward as required to adjust or balance it.
For the purpose of applying a break (or breaks) in going down hill without
bringing the weight on to the horse's back we fit the break to an arm or arms bolted
or otherwise fixed to and projecting forward from the front of the body. By moving
back the body on the frame in the manner before described the break is brought in
contact with the wheel.

Improvements in Dog Carts and other Two-wheel Vehicles.
We ALFRED GEORGE MARGETSON, of the Bristol Wagon Works, Bristol, Engineer,
and WILLIAM STUDLEY HEK, of the same place, Foreman Wheelwright, 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:-
The objects of our invention are to construct dog carts and other two-wheel
vehicles in such manner that the body can be readily adjusted or balanced in
accordance with the number of passengers carried, the distribution of the load or the
inclination of the road, and that a break or breaks can be applied in going down hill
without bringing the weight on to the horse's back as is the case with the breaks
usually employed on two-wheel vehicles.
For the purpose of enabling the body of the vehicle to be readily adjusted or
balanced we have below the body a frame which is connected to the shafts and is
made separately from the body. On each side of this frame is fixed a longitudinal
bar the front portion of which is toothed like a rack for a sufficient distance to
give the necessary travel to the body to and fro. To each side of the body are
attached two brackets that carry small wheels which are grooved or flanged and
run on the longitudinal bars before described; the two front wheels are also toothed
so as to work into the racks or toothed portions of the said bars, these front wheels
are connected together by a horizontal spindle. Outside the body at one side is an
upright spindle fitted at top with a handle within reach of the driver. This spindle
has a worm at its lower end gearing with a wheel on the horizontal spindle. By
turning the handle in the one direction or the other the body can be moved back-
ward or forward as required to adjust or balance it.
For the purpose of applying a break (or breaks) in going down hill without
bringing the weight on to the horse's back we fit the break to an arm (or arms)
bolted or otherwise fixed to and projecting forward from the front of the body. By
moving back the body on the frame in the manner before described the break is
brought in contact with the wheel.
The annexed drawings represent a dog cart in which our improvements are
embodied. Figure 1 is a side view with the body in position for a level road, the
break being off, and Figure 2 is a similar view with the body moved back for going
down hill, the break being on; in these figures the shafts are shown as cut away
in order that the mechanism for moving the body may be more clearly seen.
Figure 3 is a plan of the under frame and of some of the parts that aro fixed to
the body.
A, A represent the shafts of the vehicle. B is a frame connected to the shafts and
situated below the body C and made separately therefrom. D, D are longitudinal
bars fixed to the two sides of the frame B; the front portion of these bars is
toothed like a rack for a sufficient distance to give the necessary travel to and fro
to the body C. To each side of the body are attached two brackets E, E that carry

page_text: small wheels F, F which are grooved or flanged to run on the bars D, D; the two
front wheels are also toothed to work into the racks of the bars. G is a spindle con-
necting these front wheels. His an upright spindle fitted with a handle J within
reach of the driver. The spindle H is formed with a worm K gearing with a wheel L
on the spindle G. By turning the handle J in the one direction or the other the body
C is moved backward or forward as required to adjust and balance it. M is a break
fitted to an arm N bolted to and projecting forward from the front of the body C.
When the body is moved back on the frame B the break M is brought in contact
with the wheel of the vehicle, as seen in Figure 2, without bringing the weight on to
the horse's back.
said
Having now particularly described and ascertained the nature of our
invention, and in what manner the same is to be performed, we declare that what
we claim, in respect of dog carts and other two-wheel vehicles, is :-
1. An arrangement consisting of racks, wheels, worm and operating handle, sub-
stantially as hereinbefore described, whereby the body of the vehicle can be moved
backwards or forwards on an under frame so as to adjust or balance it, as set forth.
2. In combination with an arrangement such as is claimed in claim 1 for moving
the body of the vehicle, we claim a break fixed to and moving with the said body as
hereinbefore described so as to come in contact with the wheel of the vehicle when
the body is moved back.
