A THREE WHEEL CAB
Year: 1885

page_text: JAMES HOARE Beer House Keeper 19 Compton Street Clerkenwell do hereby
declare the nature of my invention for A THREE WHEEL CAB and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to a three wheel cab to seat four people.
To be 36 inches wide in the front which front shall be concave with a fall inward
to the centre of 12 inches.
The doors to be on each of the front sides which doors shall be concave or bent
inward and shall be 22 or 24 inches wide and to be on an angle.
From the doors to the back or end of the cab the body shall be 50 inches wide
and 40 inches long inside measurement.
The seats to be placed each side as in an omnibus and to be 15 inches wide each
seat and to be 40 inches long, and to allow 20 inches between seats for knee room.
The bottom or floor to be 30 or 36 inches wide from the back to the doors where
it shall widen out to 50 inches to facilitate the entry or exit.
The centre of the roof shall be 36 inches wide from the back to the doors, where
it shall widen out the full width of the cab and then fall in to the front.
The roof from the doors to the back from its width of 36 inches shall drop
4 inches which shall be used for ventilation as in a tramcar, glass, wood or any
other material being used as I may think best, the roof then to widen out the full
width of the cab.
The height from floor to roof shall be 64 or 66 inches from the front to the
back of the doors, and from there to the end of the cab for 36 inches the centre
width of the roof.
The sides shall be 41 inches from the top of the cushion to the roof and 20 inches
from cushion to floor.
The 36 inches centre of roof only to have a rail for carrying luggage.
To have two windows in the concave front two windows each side, one window
in the back and a concave window in each door.

page_text: The body from 41 inches, from the roof shall recede or fall under to the width
of the bottom after the style or build of an omnibus.
I shall use a crank or bent axle for the bind wheels which shall be 42 inches in
diameter with ordinary springs.
The front carriage shall consist of two wheel plates 20 inches or more in diameter
the lower or bottom wheel plate to have bolted or wheldid on each side from back
to front two pieces of T iron 1 or 2 inches wide or stouter as I may think best,
shaped like the front of the letter K the flat sides of the T iron to face each other.
To be tied in the centre by having wheldid to them a round plate 5 inches in
diameter.
And to be secured at the bottom ends by having a piece of angle iron from one
to the other and bolted together.
Between the flat sides of the T iron from the centre to the bottom shall slide up
and down two 2 or 3 inch metal boxes or bearings having flanges or guides to
keep them in their places.
The bearings or boxes to have a stubb or projecting point on the top to hold
secure the lower end of a spiral spring which spring shall also be secured at the
top to the centre plate attached to the middle of the T irons.
The axeltree to be fixed in the stock of the wheel, the ends to revolve in the
boxes or bearings which shall be providid with lubricators.
. Or I may think it best to fix the axle both sides and let the wheel revolve on
the axle in the ordinary way.
Now to prevent the side or laterial motion I must go back to the lower wheel
plate which shall have two half circles, each of 6 inches wide wheldid on each side
of the wheel plate.
From each half circle shall be two stays or supports of round iron or other
metal (light or heavy as I may think best) to the bottom of the T irons on each
outer side.
From the front of the lower wheel plate shall be a stay to the centre of the
splinter bar, and from the two half circles, one on each side of the wheel plate,
shall be two stays one on each side.
Now joined to the two half circle stays as I shall call them shall be two stays
from the lower end of the T iron wheldid together near the splinter bar.
There shall also be two other stays from the inside of the lower end of the
Tiron leading up to the centre of the splinter bar.
In order to still further explain my invention and that it may be well under-
stood I shall now proceed more particularly to describe the same reference being
made to the accompanying sheet of drawings like letters of reference indicating
corresponding parts in the respective figures.
Figure 1 is a top view of my three wheel cab or carriage Figure 2 is a front
view Figure 3 is a side view thereof and Figure 4 is a back view.
In carrying out my invention I make the front of my cab or carriage concave
as shown in (Fig. 1) to enable the front carriage and wheel to revolve, and to place
it as near as possible to the hind wheels and by so doing insuring the stability of
the vehicle, I also shew the position of the doors B. B. and the seats inside C. C.
The front of my cab or carriage shall be concave from the top to the bottom
and shall have two concave windows as shewn in (Fig. 2 the doors D. D. shall
also be concave and placed on an angle to the full width of the cab E. E. from
which angle the roof is reduced in height on each side to insert ventilators F. F. as
shewn in (Fig. 3) and carrying luggage as near as possible on the centre of the
roof G. as shewn in (Fig. 4).
The lower wheel plate H. of my front carriage shall have attached to it on each
side two pieces of what is termed T iron as shewn in (Fig. 3) and lettered L. I.
sloping in to the centre where they are attached to a round plate J. from which.
point they decend perpendicular to the bottom, the two ends are then held secure
by pieces of angle iron K. bolted to the T irons, between these aforesaid T irons

page_text: from the centre to the bottom shall be placed two boxes or bearings L. wherein
the axle revolves.
To the centre plates J. shall be attached two spiral springs M. as shewn in
(Fig. 3) secured at the base by two stubbs or projections attached to the above
mentioned boxes or bearings L.
For preventing the lateral motion and rendering the front carriage rigid, I attach
to the lower wheel plate, two half circles N. N. as shewn in (Fig. 1) to which shall
be attached two rods O. O. as shown in (Fig. 3) of iron or other metal, secured to
the lower end of the centre or as before named T irons and lettered I. I.
The splinter bar P. shall also be attached to the wheel plate by a rod J. of iron
or other metal in the centre, and from each half circle N. N. attached to the wheel
plate shall be two rods or levers R. R. as shewn in (Fig. 1) and joined or wheldid
to which shall be two rods leading down and fastened to the lower ends of the
Tirons and lettered S. S. as shewn in (Fig.) 2.
There shall be two more rods or levers rising from the bottom ends of the centre
or Tirons to the middle of the splinter bar and lettered W. W. in (Fig. 2).
•
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The general construction of the Vehicle.
The construction of the front carriage which can be used for other Vehicles.
The concave front to enable the front carriage and wheel to revolve thereby
bringing the hind wheels and the front wheel as close as possible to insure the
stability of the vehicle.
The construction and arrangement of the doors being concave and placed on each
of the front sides and at an angle as aforesaid.
The widening out of the floor near the doors and the increase of the width of
the roof over the doors.
The arrangement for carrying luggage on the three feet centre of the cab.
