PROVISIONAL SPECIFICATION.
An Improved Method of Steering or Guiding Wheel Chairs and.
other Vehicles from the Rear.
I SEPTIMUS LALONDE, of High Street in the Town of Weston-super-Mare, in
the County of Somerset, House Furnisher, do hereby declare the nature of this
invention to be as follows:-
:
My invention consists of a method by which a person pushing an invalid chair or
other vehicle at the back may steer or guide it alone. In order to do this the
pushing handle at the back is made to revolve on its axis and at each end of the
same, between guides, is fixed a chain. Each of these chains is caused to pass
suitably under the chair to the front or guiding wheel.
The front wheel being provided with arms of suitable length projecting on each
side of the guide. wheel. At the end of each of these arms is fixed: one of the
chains above referred to. One of these chains is attached to the front of the
revolving handle and the other to the back, so that by turning the handle forward
or backward one chain becomes shortened and the other lengthened, and vice versa,
thus pulling round the guide wheel on the shortened side to whichever way it is
desired the chair or vehicle should turn. In order to keep a proper tension upon
the chains a spring is placed in any part of the length of each chain, attached to
the body of the chair, or vehicle.

COMPLETE SPECIFICATION.
An Improved Method of Steering or Guiding Wheel Chairs and
other Vehicles from the Rear.
I SEPTIMUS LALONDE of High Street, in the Town of Weston-super-Mare in
the County of Somerset, House Furnisher, 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 :-
My invention consists of a method by which a person pushing an invalid chair
or other vehicle at the back may steer or guide it alone.
In order to do this, the pushing handle at the back is made to revolve on its axis,
and at each end of the same, between guides, is fixed a chain wire, cord, or other
suitable connection. Each of these chains or wires, &c., as aforesaid is caused to
pass suitably under the chair to the front or guiding wheel.
The front wheel being provided with arms of suitable length projecting on each
side of the guide wheel. At the ends of each of these arms is fixed one of the
chains, wires, or cords before referred to. One of these chains, wires, or cords, is
attached to the front of the revolving handle, and the other to the back, so that by
turning the handle forward or backward, one chain, wire, or cord becomes shortened
and the other lengthened, and vice versa; thus pulling round the guide wheel on
the shortened side to whichever way it is desired the chair or vehicle should turn.
In order to keep a proper tension upon the chains, wires, or cords, pulley wheels,
with or without springs, are placed in the most suitable places on the chair along
the length of each chain, wire, or, cord.
Fig. 1 is a section of the chair, a, is the pushing handle which revolves on its axis.
b, b, are the chains, wires, or cords. c, the guides. d, the arm projecting from the
guide wheel, and e, e, are the pulley wheels.

page_text: Fig. 2 is a plan of the chair, a, is the pushing handle as aforesaid, b, b, are the
chains, wires, or cords, which are shewn by dotted lines running under the chair,
c, c, are the guides to prevent the chain (&c.) running off the handle, d, d, are the
arms projecting from the guide wheel to which the chains (&c.) are attached.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
An improved method of steering or guiding wheel chairs and other vehicles from
the rear, by means of a pushing handle, revolving on its axis, having chains, wires,
or cords, from the same connected with arms projecting from the guide wheel as a
means of turning the same whichever way it is wanted to go; all substantially as
described in the Specification, and as shewn on the drawings annexed hereto.
Dated this 31st day of July 1893.
