IMPROVEMENTS IN CABS
Year: 1884

page_text: I, WILLIAM JOHN BREWER, of 23 Rood Lane, Fenchurch Street, in the City of
London, Civil Engineer, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN CABS" to be as follows:-
My Invention relates to an improved Cab designed to ride easily, to turn freely
and in a small space, and to be accessible and commodious for the rider.
Upon the axle of a pair of large bearing wheels preferably as patented to me
under No 1862, 12 Apr. 1883 and 5000 17 March 1884.
I mount my Cab body as near the centre of gravity as may be. The entrance to
the body is by means of two doors at the front, which, opening outwards, are
swung on lateral hinges at an angle, so as to cut off the two front corners of the
body. The opening and closing of the doors is effected by means hereinafter
specified.
Under the front of the body is a trailing castor bearing, carrying a wheel of
small diameter, but wide periphery. The journal bearings are boxed in to prevent
entry of dust and dirt, and are formed of any suitable anti-friction metal such as
manganeze. I further provide. a brush pressing in a groove in, or against a
shoulder in, the axle to prevent dirt working in.
The shafts or pole I fix so as to have perfectly free lateral play and this I effect
either by mounting it or them upon a vertical hinge or free to slide upon a sémi
circular bracket. This will allow of the cab turning in its own length and will
permit of the doors being brought close against the curb.
The doors are actuated either directly by a handle, by the driver from his box,
or by the rider from his seat-In the frame against which the edge of the door
closes are springs, which are in compression when the door is shut, but which
immediately upon its release cause it by their reaction to fly open. The Cross head
of the door latch is pivotted to a vertical lever, which is the lowest of a series of
jointed levers, the uppermost being provided with a push within reach of the
driver, who can thus release the door at any time. For the convenience of the
rider a set of cords running over suitable pulleys in the roof or sides of the cab
controls the cross head of the latch.
A quadrant or guide is provided in the travel of the door and is fitted with stops.
so that the door may be held at any desired angle of aperture.
In place of hinged doors, I may employ sliding doors, and in this case the door
when shut holds spring stops in compression as before and is controlled by either -

over pulleys to the coachman to enable him to close the door.
To ensure ventilation in the Cab, I fix an upright pipe having in its orifice an
inner case and surrounding its orifice an outer cone with an upper cowl. The
upward draught between the two cones causes the air to be drawn through the
upright pipe from the interior of the Cab-A shutter or valve inside the Cab will
permit of the rider regulating or closing the orifice.

and
I, WILLIAM JOHN BREWER, late of 23 Rood Lane, in the City of London, but
now of 2 Victoria Mansions, in the City of Westminster, Civil Engineer do
hereby declare the nature of my Invention for "IMPROVEMENTS IN, CABS"
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 an Improved Cab designed to ride easily, to turn freely,
and in a small space, and to be accessible and commodious for the rider.
In order that my invention may be the better understood I now proceed to
describe the same in relation to the drawing hereunto annexed and to the letters
and figures marked thereon. Like letters refer to like parts throughout the
figures.
Referring to the general elevation Figure 1. and Plan Figure 2. of my improved
Cab :-
Upon the axle of a pair of large bearing wheels, preferably as patented to me under
number 1862 12th April 1883 and N° 5000 17th March 1884 I mount my Cab body
as near the centre of gravity as may be--The entrance to the body is by means of
two doors A. at the front, which, opening outwards, are swung on lateral hinges B,
at an angle, so as to cut off the two front corners of the body-The opening and
closing of the doors is effected by means hereinafter specified-At the front of the
body is a spring bearing carrying a Wheel of comparatively small diameter.
The journal bearings of all the Wheels are boxed in to prevent entry of dust
and dirt.
The detail of the boxing in of the main bearing wheels is shown in figures 3
and 4-On reference to my earlier patents aforesaid it will be found that the
bearing of my Wheel is taken by a sliding block sliding in a groove C. in a
second block containing a spring-This Groove is closed by means of a plate or
plates D. to prevent entry of dust-In the case of tlie front wheel, the sliding piece
and spring are enclosed in a Cylindrical Casing E, and the play of the sliding piece.
takes place through a suitable packing.
The journal bearings are formed of any suitable anti friction metal, such as
Manganese, and in order to further obviate the entry of dust to the main bearing
wheels, I may provide a brush pressing into a Groove F, Figure 4, or against a
shoulder on the axle to prevent dirt working. in.
The shafts or pole I fix so as to have perfectly free lateral play, and this I effect
either by mounting it or them upon a vertical hinge or pivot as shown in Figure 1,
or free to slide upon a semicircular bracket. This will allow of the cab turning in
its own length, and will permit of the doors being brought close against the kerb―
The doors are actuated either directly by a handle, by the driver from his box, or
by the rider from his seat. In the frame of the cab, against which the edges of the
doors close, are springs G, shown in enlarged detail in Figure 5, which are in
compression when the doors are shut, but which immediately upon their release
cause them by their reaction to fly open.
'
_ Referring now to the enlarged detail shown in Figure 6-The spindle of the
door latch is furnished with a cross piece H working in a mortise in the substance

page_text: of the door, and this cross piece is pivoted to a vertical bolt K, which engages with
a hole in the frame of the cab against the spring pressure of a stop L. This stop L
is pivoted to a bell crank M which is under the control of the driver by means of
the rod N. Upon the driver pulling the rod N the bell crank will depress the
stop L and press the bolt K out of the hole in the frame of the cab, thus leaving
the door free to be thrown open by the reaction of the springs G, a Second bolt may
be applied as shown For the convenience of the rider a set of cords running over
suitable pullies in the roof, or at the sides of the cab, may control the cross head of
the latch. and bolts aforesaid Quadrants or guides O are provided in the travel of.
the door, and are fitted with stops or holes at any desired angle of aperture-In
place of hinged doors, I may employ sliding doors, shown in detail in Fig: 7,
A. A being the doors and P being the Chamber in the frame of the cab into which
they slide. In this case it will be seen that the front of the cab must be formed of
a semicircular form in order to permit of. the travel of the doors. Suitable spring
stops may be supplied as before described and the travel of the doors may be
controlled by means of cords led over pulleys for the Coachman or Rider. To
ensure Ventilation in the Cab, I fix one or more upright pipes having at the orifice
of each of them an inner cone S (Figure 8) and surrounding its orifice an outer
cone S¹ with an upper cowl T. The upward draught caught by the wind, or the
draught created by the travel of the Cab, causes the air to be drawn 'through the
upright pipe from the interior of the Cab. A Shutter or Valve U of any suitable
form inside the Cab will permit of the rider regulating or closing the orifice..
At the back of the Cab I provide a rumble or seat, and this rumble is detachably
hinged to the body, so that it may be taken off if required, or by means of a
suitable arrangement of jointed supports, it may be folded against the body when
not in use. The jointed supports, as shown, are held rigidly in position, when
expanded, by the cross piece W which engages with a hook in the body of the Cab.
On release of this hook, the joints X X being folded in contrary directions
(X inwardly) permit of the seat being folded against the body of the Cab. This
would be found useful in cases where stable room is limited, or where the driving
is effected from the interior of the Cab.
Having now fully described the nature and object of my invention and the
manner of its performance I declare that what I claim is
The complete or partial combination in an improved Cab of my special
devices, viz :-
The special arrangement of doors swung on lateral hinges and controlled by
means of levers or cords by the Driver or the rider; the vertical pivoted front
wheel permitting of handiness in the Cab: the boxing in of my special axles to.
prevent entry of dust and dirt; the employment of a brush for the same purpose;
The mounting of the shafts to allow of lateral play; the quadrant device to allow
of the door being at any angle of aperture; of a special Ventilator; and a
detachably hinged and folding rumble or seat, all substantially as and for the
purposes specified.
