Improvements in the Means or Mode of Adjusting the Seats of
Two-wheel Vehicles known as Dog Carts.
1 WILLIAM HENRY BRITTAIN of the firm of T. Brittain & Sons, Carriage
Builders Bristol Street, Birmingham, do hereby declare the nature of my said
invention to be as follows:-
My Invention consists in the construction and arrangement of parts by means of
which the seats of vehicles known as Dog Carts can be adjusted to accommodate two
or four persons as may be required.
At the back of the vehicle interiorly is arranged two cranked levers, each one near
to each side, a connecting rod is arranged from cach crank to the inner part of
the door and near to each end, the other ends of the cranked levers is provided with
levers working upon a common centre, while the extreme end of each said lever is
secured at or near the seat and at the back of the driving seat but working upon a
pin and plate in connection with the movable seat, that is the seat capable of adjust-
ment, which is effected as follows-The door which is at the back of this class of
vehicle is now up or closed and the movable seat is concealed or partly so, so that
only two persons can ride and at the front but by bringing down the door, the
rods, cranks, and levers are brought into operation and the seat brought out for use
the door forming the foot board. The action reversed again closes and conceals the
seat.

Improvements in the Means or Mode of Adjusting the Seats of
Two-wheel Vehicles known as Dog Carts.
I WILLIAM HENRY BRITTAIN of the firm of T. Brittain & Sons, Carriage
Builders, Bristol Street Birmingham, do hereby declare the nature of my said
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 in the construction and arrangement of parts by means of
which the seats of vehicles known as Dog Carts can be adjusted to accommodate two
or four persons as inay be required.
At the back of the vehicle interiorly is arranged two cranked levers each one near
to each side. connecting rod is arranged from each crank to the inner part of the
door and near to each end. The other ends of the cranked levers are provided with
levers working upon a common centre, while the extreme end of each said lever is
screwed at or near the seat and at the back of the driving seat but working upon a
pin and plate in connection with the moveable seat, that is, the seat capable of
adjustment, which is effected as follows: The door which is at the back of this class
of vehicle is now up or closed and the moveable seat is concealed or partly so, so that
only two persons can ride and at the front, but by bringing down the door, the rods
cranks, and levers are brought into operation and the seat brought out for use, the
door forming the footboard." The action reversed again closes and conceals the seat.
And in order that this my said invention may be more clearly understood I will
now proceed to describe it with the assistance of the accompanying sheet of
drawings, similar letters of reference denote similar parts in each figure in which
they occur.

page_text: Fig. 1 is a longitudinal section, through the body of a dog cart to which my
invention is applied.
Fig. 2 is a cross section of the same.
Fig. 3 is a plan view of the same with the seats removed to show the parts
beneath.
Fig. 4 is a longitudinal section through the body of a dog cart to which a
modification of my invention is applied.
of
Fig. 5 is a longitudinal section through the body of a dog cart with a modification
my invention applied.
a is the body of the dog cart in all the Figures-b is the front seat which is
made moveable so as to be placed either nearer to the front or nearer to the back
as desired, it slides in guides a¹ provided for the purpose.-c is the back seat of
the dog cart Figs. 1-4. d is the door or back of the dog cart-sometimes
called the cratch." e is the floor of the dog cart.
When it is desired that both seats of the dog cart shall be occupied it is
necessary to let down the back d into the position shown in full lines figures 1.
3. 4. 5. The front seat 6 is then in its forward position as shewn at b figure 1.
When only the front seat is to be occupied it is necessary for the sake of
properly balancing the dog cart to push the front seat farther back into the
position shewn at b₁ the door d. must then also be closed that is brought into the
position shown by the dotted lines at d¹ in Figs. 1. 4. 5.
These movements of the front seat and the door or hinged back d are simul-
taneously effected by my invention so that the one movement cannot take place
without the other, by the following means I will first describe my invention in
its primary form as illustrated in Figs. 1. 2. 3. f is a fixed cross rail extending
from one side of the dog cart to the other under the front seat. To this rail are
affixed two fulcrums g g-On these fulcrums work bent levers hh, one to each.
The long arms of these levers are provided with slots h¹ h¹. The under side of
the moveable front seat 6 is provided with a pin 62 which engages in the slotted
ends of the levers hh (see Fig. 3). The other ends of the levers hh are jointed
at 22 by means of universal joints to the rods j; the outer ends of which are
connected by means of proper joints with the hinged back d at_d² d. The
rods jj are close to the sides of the dog cart and are provided with proper
guides k k.
It is evident from the Figs. 1 and 3 that if the seat b with its pin 6 be
pushed back then the levers hh will assume their dotted position, and the back
or door d will be closed.
Fig. 4 shows a modification of my invention in which straight vertical slotted
levers are used instead of the bent horizontal ones- is one of the levers, slotted
at and moveable on a fulcrum m. The end of this lever is connected with
the door d by a rod j. The lever is also provided with a handle 8.
In this modification there will be a set of levers on each side of the dog cart
so as to ensure smoothness in working. Or by employing a rod fixed at p (that
is the front edge of the seat c) and connected to the lever at any position
between m the fulcrum, and 12 being the end of 1. Take Fig. 4 with the rod
affixed as above described and by raising the handle the front seat b is taken
back, and the back seat c is brought forward and hidden under the front seat b. This
will be of advantage when the front seat only is occupied as the back part of the
cart will be clear for luggage.
In connection with the handle 3 I propose to employ a suitable fastening so
that when the door d is up or closed it cannot be surreptitiously opened as when
the back is occupied with luggage.
The above being my said invention I wish to say that 1 do not limit myself to
the precise details or arrangement of parts as shown on the accompanying sheet
of drawings but that I hold myself at liberty to alter or modify the same with-
out departing essentially from my said invention.

page_text: 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
1st. The movement of the front seat of the vehicle, to the desired position by
the movement of the door, simultaneously effected by parts arranged, combined,
and operating substantially as herein before described in the foregoing Specification
and illustrated in Figs. 1. 23 of the accompanying sheet of drawings and for the
purposes specified.
2nd. The movement of the front seat of the vehicle to the desired position by
the movement of the door, or the movement of the front seat and the back seat
to a desired position by the movement of the door in either case simultaneously
effected by parts arranged, combined and operating, substantially as hereinbefore
described in the foregoing Specification and illustrated in Figs. 4. 5 of the accom-
panying sheet of drawings, and for the purposes specified, the whole forming
Improvements in the means or mode of adjusting the seats of two wheeled
vehicles known as Dog Carts.
