PROVISIONAL SPECIFICATION.
Improved Means and Appliances for Opening and Closing Cab Doors.
We, MOSES SMITH, of 75 Great York Mews, Baker Street, Oxford Street,
Middlesex, Cab Builder and CHARLES ALEXANDER WHEELER, of 133 Railway
Cottages, Willesden, Middlesex, Engineer, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to means and appliances by which cab and carriage doors
can be opened from the driver's seat, whether he sits in front as with Clarence cabs,
or behind as with Hansom cabs, to enable persons to enter, but which doors can be
opened freely by the occupants to get out as is usual, the mechanism reversing itself
by the pressure put upon the door to open it.
For the purpose of this invention, if fitted to a Hansom cab and to which it is
more applicable, the door proper has on its inner side, a couple of lugs in which a
bolt can rise and fall. This bolt is jointed to a curved bar link, the opposite end of
which is attached to another bar-like link, which is jointed to a plate affixable to the
body of the vehicle.
We employ a spindle which passes upwards just behind the front upright and has
a bevil pinion on its upper end in gear with a wheel having a lever attached to its
collar. This lever leads up to a bell crank and a handle is arranged within reach of
the driver, which on being pulled over a quarter of a circle gives motion to the door
and opens it.
If the door be formed in two halves, as is usual with the present style of Hansom's,
a set of the appliances is applied to each half door, which may, if desired, be operated
by a single handle at the upper part.
For Clarence cabs and carriages having side doors, the appliances are so fitted
that the driver can operate the handles for opening the door without moving from
his seat.
The invention is subject to various modifications according to the contour of the
front of the cab, if for the Hansom tribe, particularly, the shape of the curved bar
link and the distance to which the bolt in the lugs may travel.
Instead of the holt and the curved bar link being connected to the door, as
described, it may be attached to the body of the vehicle and the bolt be used as a
spindle for operating the other parts.

For the purpose of this invention which is specially applicable to a Hansom cab, as
indicated by the annexed drawings,
Figure 1 being a side elevation from inside the cab body.
Figure 2 a view of the apparatus at right angles and
Figure 3 a plan of the lower levers.
The door proper A has on its inner side, lugs B, B, to which is jointed a curved
bar link D, the opposite end being attached to another bar like link E which is jointed
to a plate F projecting from a spindle H which passes upwards at an angle and has a
bevil pinion I on its upper end in gear with a wheel J having a lever K attached to
its collar. This lever leads by a rod L up to a bell crank M and a handle N arranged
within reach of the driver, which handle on being moved over a quarter of a circle
gives motion to the door A and opens it.
If the door be formed in two halves, as is usual with the present style of Hansom's,
a set of the appliances is applied to each half door which may if desired, be operated
by a single handle at the upper part.
For Clarence cabs and carriages having side doors, the appliances are so fitted that
the driver can operate the handles for opening the door without moving from his seat,
for which purpose the doors are hinged in the reverse direction, i.e. from the front.
The invention is subject to various modifications according to the contour of the
front of the cab, if for the Hansom tribe, particularly the shape of the curved bar link
and the distance to which the bars may travel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. The arrangement of appliances shown on the annexed drawings for enabling cab
and carriage doors to be opened and closed by the driver, as set forth.
2. The two curved bar links D, E, connecting the door of a cab or carriage with a
rotatable spindle, as and for the purpose described.
