Year: 1885

page_text: I, EDWIN POWELL, of Charles Street, Wolverhampton in the County of Stafford,
coach builder, do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR OPENING AND CLOSING THE DOORS OF HANSOM CABS, to be
as follows:-
The object of this inveution is to provide efficient and simple means whereby
the doors of Hansom cabs may be readily opened and closed by the driver without
dismounting from his seat at the back of the cab.
A wheel, having a grooved periphery, is formed with or carried by the part of
each upper hinge which is fixed to a door, and in such position as to be concentric
with the hinge-pin; and this wheel in each case acts also as the tongue of the
hinge and takes, consequently, within the jaw formed by the opposite part of the
binge.
The doors are opened and closed by means of chains or cords passing around
the pulleys and fixed thereto at some convenient point in the circumference of the
pulley. A connection is formed between the chains or cords, which actuate the
pulleys, and a handle or treadle in convenient position to be operated by the driver,
as follows:-A vertical double-ended lever, or double quadrant-ended lever, is
carried upon a fulcrum on each side of the inside of the body of the cab, and the
two ends of each cord or chain are connected, respectively, to the ends of the levers.
Two L-shaped levers are carried upon the inside seat underneath the cushion.
These levers are fulcrumed at their angles so as to work in a horizontal plane, and
in such position that one arm of each lever extends outwards towards the side of
the cab and the other arm extends backwards. The two back ends of the back-
ward arms are joined together with a link so as to act together, and the outward
ends of the other arms are connected, by means of short links, with the lower ends
of the double-ended or quadrant-ended levers first described, and these last-
described links are provided with universal joints to allow of the motion of the
levers and arms. The link joining the back ends of the L-lever arms is moved
transversely of the cab by means of a vertical lever inside the back of the cab fixed
to a short spindle passing through the back of the cab and having a double-ended

page_text: treadle upon the outward projecting end, so that by depressing one end of the
treadle the link will be moved in one direction and by depressing the other end of
the treadle the link will be moved in the opposite direction; or a vertical, or
approximately vertical, spindle may be carried up inside the back of the cab
terminating at its lower end in a lever connection with the link and passing up
through the top of the cab and terminating in a handle in convenient position for
the driver.
The end connections between the outer ends of the arms of the L-levers and the
links to the vertical side levers are slotted, one of such slots having a lead in
relation to the other, so that the door which overlaps the other at the centre is
first commenced to be opened so as to allow sufficient clearance for the opening of
the other door, and so that the reverse operation takes place in closing the doors,
that is so that the door which is the last to be opened is the first to be closed.
When quadrant ends are used for the side levers the chains or cords of course
bear around the peripheries of such quadrants.
In lieu of the slotted connections, before-described, knee-joints, limited as to
their degree of angularity, may be employed.
The chains or cords are of course guided between the levers and pulleys by
suitable pulleys or other guides as may be necessary.

page_text: COMPLETE SPECIFICATION,
Improvements in Apparatus for Opening and Closing the Doors
of Hansom Cabs.
I, EDWIN POWELL, of Charles Street, Wolverhampton in the County of Stafford,
coach builder, 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, reference being had to the accompanying drawings, and
the letters of reference marked thereon (that is to say):-
The object of this invention is to provide efficient and simple means whereby
the doors of Hansom cabs may be readily opened and closed by the driver without
dismounting from his seat at the back of the cab.
Figure 1 of the accompanying drawings is a longitudinal section through the
centre of the body of a Hansom cab having my improved apparatus for opening
and closing the doors applied thereto. Sufficient only of the cab is shewn to make
the application of the invention clear. Figure 2 is a sectional plan taken on
line of figure 1, but one side of the cab is shewn as if broken away, for con-
venience of illustration, and other parts not necessary to illustrate the invention are
omitted.
Similar letters of reference occurring upon both these views indicate corre-
sponding parts.
A A is the body of the cab, B the right-hand door pillar, and C the right hand.
door shewn open.
a is a grooved wheel formed with or fixed to the flap 6 of the
upper hinge, that is the part of the hinge which is fixed to the door C, so that as
the wheel is moved axially the door turns therewith. The hinge pin c passes
through the centre of the wheel a, and the wheel a thus acts as the tongue of the
hinge and takes, consequently, within the jaw formed by the opposite part 1 of
the hinge. d is a vertically-mounted lever carried upon a stud e projecting from
a plate fixed inside the body of the cab. a and c are links connected each at
one end with the lever dat equal distances on opposite sides of the fulcrum c.
d'd etc. is a chain or cord which passes from the forward end of the link a¹ under
a grooved pulley el, at the back of a grooved pulley f³, around the outside of the
wheel a, and thence around the inside thereof behind the pulley g, under the
grooved pulley g, and thence to the nearer end of the link c', to which it is
connected. It will thus be seen that the lever d, links a¹ and cl, and cord or
chain dd etc., together form in effect an endless cord or chain. The pulleys e¹
and g are mounted vertically between a plate fixed inside the cab, and a
guard h¹ fixed to such plate, and the pulleys f¹ and g are mounted in, an inclined
position between jaws or snugs projecting from such plate, as shewn, so as to guide
the chain or cord between the pulleys e¹ g' and the wheel a. The chain or
cord d d etc. is fixed to the periphery of the wheel a by means of a stud or peg j,
so that such wheel is moved axially as an endway movement is given to the chain

page_text: or cord. and are screwed sockets for adjusting the lengths of the links a¹
and c, respectively, and thus adjusting the exact position of the chain or cord in
relation to the wheel a. kare horizontally-mounted levers fulcrumed to
studs upon plates fixed upon the seat-board D of the cab. m m² are arms
formed with the levers kk², respectively. n is a link connecting the outer end of
the arm m with a universal joint n¹ upon the end of a link o; and this link o is
connected at its other end with the extreme lower end of the lever d. p is a bar
connecting together the hinder ends of the levers k k', and p¹ is a transverse sluice
in the centre of the bar p. q is a vertical rod passing down inside the back of the
cab, as shewn. The lower end of this rod is cranked, and the bottom of such
cranked part fits within the sluice p¹. The top of the rod is fitted with a handle q',
in position to be readily operated by the driver whilst seated at the back of the
cab. As the handle is moved in one direction, the bar p is moved endways in a
direction indicated by the arrow r, carrying with it the back ends of the levers k
and . The outer end of the lever m is consequently moved backwards, and so is
therefore the lower end of the lever d, and the chain is consequently pulled in such
direction as to turn the wheel a in the direction to close the door C. Upon the
handle being moved in the reverse direction, the opposite effect is, of course,
produced, that is the door is again opened. Duplicate mechanism is carried within
each side of the cab, except that the chain or cord passes in the reverse direction
relatively around the wheel a on one side to its direction around the wheel a on
the other side, so that both doors may be opened and closed together.
In the position in which the levers l l are shown in figure 2, both doors are
wide open.
C is that door which underlaps the other door of the pair. 8 s' are.
slots in the ends of the bar p; and in the relative positions of the levers le k¹ and
bar
P, as shewn in figure 2, the pins connecting the levers with the bar pass
through the outer ends of the slots. As the bar is moved in the direction of the
arrow r, to close the doors, the back end of the lever k is simultaneously moved in
the same direction, and the door C commences to close. After the bar has been
moved sufficiently, in the direction described, to bring the inner end of the slot 8¹
against the pin therethrough, the back end of the lever moves simultaneously
with the bar. A lead is thus given in closing to the door C. Each door is moved
by the mechanism in closing until up to the point when it has a tendency to fall
inwards and close itself. At such point the door C operates through the mechanism
and causes the back end of the lever k to advance more rapidly in the direction of
the arrow r, until the pin through the slot s comes against the inner end of the slot,
after which the door is held by the mechanism from closing too rapidly. Shortly
after the door C has passed the point at which it has a tendency to fall inwards,
the other door passes its corresponding point, with the effect of moving the pin
through the slot s again rapidly into position against the outer end of the slot,
after which this door also is held by the mechanism from closing too quickly.
It will now be seen that the door C (that is the underlapping door) will close first,
because, after the doors have passed the point in closing at which they have a
tendency to fall inwards, the pin through the slot & is at the inner end of the slot,
whereas the other pin is at the outer end of the slot s¹. As the bar p is continued
to be moved in the direction of the arrow r, after the door C has been closed, the
other door is also closed, and the slot 8 is moved into position with its outer end
against the pin therethrough; so that when both doors have been closed, the pins
through the slots & s', respectively, are against the outer ends of the slots. As the
handle q is moved to traverse the bar p in the reverse direction to the arrow r, to
open the doors, the reverse action. to that already described takes place, as will
now be readily understood, that is to say, the overlapping door is the first to be
opened. The length of the slots 881 is, of course, made sufficient to allow of the
necessary lead of the underlapping door in closing, and consequently of the over-
lapping door in opening.

page_text: V is a rail or bearer above the levers to carry boarding on which the cushion
is placed. Similar rails or bearers are employed near the front of the seat board,
and at the sides of the cab, so that the mechanism may be properly boxed in.
The wheel a may be fixed to the door in any convenient manner, but so as to be
in line with the axis of the hinges.
Figure 2 illustrates a means for keeping rain, snow, &c from driving into the
cab through the hole w (figure 2) in the door pillar through which the chain
passes. This view is a corresponding section to that shewn at figure 2, but only
sufficient of the parts is shown to make this part of the invention clear, and the
door C is in this case shewn closed, instead of open as in figure 2. v is a sheet
metal guard fixed to the pillar B by means of a plate v¹ to which it is brazed or
otherwise fixed. The guard vis formed to pass partly over the wheel a as well as
in front of the hole w, as shewn, and thus securely covers the hole w (figure 2).
Figures 3 and 4 illustrate a modification of the means for operating the levers k
and Figure 3 is a vertical section through part of the back and seat board of
the cab, and figure 4 is a sectional plan taken on line y of figure 3, but shewing
only sufficient of the cab to make the application of this modification clear. A¹ is
the back of the cab, and D¹ the seat board, t is a bar corresponding to the bar p
(figures 1 and 2) and u is a snug standing up on the bar t. t is a lever fixed to
a spindle passing through a mounting at the back of the cab, as shewn, and is
jawed at its lower end to embrace the snug u. A pin passes through this jaw to
connect it with the snug, and consequently with the bart; and the hole in the
enug through which the pin passes is slotted vertically to allow of the vibration of
the lever tu' is a double-ended pedal mounted on the back end of the spindle,
aforesaid, and in position to be readily operated by the driver whilst seated at the
back of the cab. Upon depressing one end of this pedal the doors are closed, and
upon depressing the other end the doors are opened. A handle may be employed,
if desired, in lieu of the pedal. The bar t is slotted at its ends similarly as the
bar p (figures 1 and 2) is slotted, and for the same purpose,
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
1. The apparatus by means of which the driver of a Hansom cab is enabled to
open and close the doors of such cab without dismounting from his seat, sub-
stantially as herein described and shewn by the drawings herewith.
2. In apparatus for opening and closing the doors of a Hansom cab, the com-
bination of a lever d on each side of the cab with a chaiu or cord d¹ d' etc. and a
wheel a fixed to, or forming part of, the portion of a hinge of a door which is fixed
to the door, or otherwise fixed to the door and in line with the axis of the hinges,
and with suitable means for adjusting the chain or cord in relation to the lever
and wheel, substantially as and for the purpose, herein described, and shewn by the
drawings herewith.

I, EDWIN POWELL, of Charles Street, Wolverhampton in the County of Stafford,
coach builder, do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR OPENING AND CLOSING THE DOORS OF HANSOM CABS, to be
as follows:-
The object of this invention is to provide efficient and simple means whereby
the doors of Hansom cabs may be readily opened and closed by the driver without
dismounting from his seat at the back of the cab.
A wheel, having a grooved periphery, is formed with or carried by the part of
each upper hinge which is fixed to a door, and in such position as to be concentric
with the hinge-pin; and this wheel in each case acts also as the tongue of the
hinge and takes, consequently, within the jaw formed by the opposite part of the
hinge.
The doors are opened and closed by means of chains or cords passing around
the pulleys and fixed thereto at some convenient point in the circumference of the
pulley. A connection is formed between the chains or cords, which actuate the
pulleys, and a handle or treadle in convenient position to be operated by the driver,
as follows: A vertical double-ended lever, or double quadrant-ended lever, is
carried upon a fulcrum on each side of the inside of the body of the cab, and the
two ends of each cord or chain are connected, respectively, to the ends of the levers.
Two L-shaped levers are carried upon the inside seat underneath the cushion.
These levers are fulcrumed at their angles so as to work in a horizontal plane, and
in such position that one arm of each lever extends outwards towards the side of
the cab and the other arm extends backwards. The two back ends of the back-
ward arms are joined together with a link so as to act together, and the outward
ends of the other arms are connected, by means of short links, with the lower ends
of the double-ended or quadrant-ended levers first described, and these last-
described links are provided with universal joints to allow of the motion of the
levers and arms. The link joining the back ends of the L-lever arms is moved
transversely of the cab by means of a vertical lever inside the back of the cab fixed
to a short spindle passing through the back of the cab and having a double-ended

page_text: treadle upon the outward projecting end, so that by depressing one end of the
treadle the link will be moved in one direction and by depressing the other end of
the treadle the link will be moved in the opposite direction; or a vertical, or
approximately vertical, spindle may be carried up inside the back of the cab
terminating at its lower end in a lever connection with the link and passing up
through the top of the cab and terminating in a handle in convenient position for
the driver.
The end connections between the outer ends of the arms of the L-levers and the
links to the vertical side levers are slotted, one of such slots having a lead in
relation to the other, so that the door which overlaps the other at the centre is
first commenced to be opened so as to allow sufficient clearance for the opening of
the other door, and so that the reverse operation takes place in closing the doors,
that is so that the door which is the last to be opened is the first to be closed.
When quadrant ends are used for the side levers the chains or cords of course
bear around the peripheries of such quadrants.
In lieu of the slotted connections, before-described, knee-joints, limited as to
their degree of angularity, may be employed.
The chains or cords are of course guided between the levers and pulleys by
suitable pulleys or other guides as may be necessary.

the letters of reference marked thereon (that is to say):-
The object of this invention is to provide efficient and simple means whereby
the doors of Hansom cabs may be readily opened and closed by the driver without
dismounting from his seat at the back of the cab.
Figure 1 of the accompanying drawings is a longitudinal section through the
centre of the body of a Hansom cab having my improved apparatus for opening
and closing the doors applied thereto. Sufficient only of the cab is shewn to make
the application of the invention clear. Figure 2 is a sectional plan taken on
line xx of figure 1, but one side of the cab is shewn as if broken away, for con-
venience of illustration, and other parts not necessary to illustrate the invention are
oinitted.
Similar letters of reference occurring upon both these views indicate corre-
sponding parts.
A A is the body of the cab, B the right-hand door pillar, and C the right hand
door shewn open.
a is a grooved wheel formed with or fixed to the flap b of the
upper hinge, that is the part of the hinge which is fixed to the door C, so that as
the wheel is. moved axially the door turns therewith. The hinge pin c passes
through the centre of the wheel a, and the wheel a thus acts as the tongue of the
hinge and takes, consequently, within the jaw formed by the opposite part b¹ of
the hinge. d is a vertically-mounted lever carried upon a stud e projecting from
a plate fixed inside the body of the cab. a¹ and c¹ are links connected each at
one end with the lever d at equal distances on opposite sides of the fulcrum c.
dd etc. is a chain or cord which passes from the forward end of the link a¹ under
a grooved pulley e, at the back of a grooved pulley f¹, around the outside of the
wheel a, and thence around the inside thereof behind the pulley g, under the
grooved pulley g¹, and thence to the nearer end of the link c', to which it is
connected. It will thus be seen that the lever d, links a¹ and c¹, and cord or

and c, respectively, and thus adjusting the exact position of the chain or cord in
relation to the wheel a. kare horizontally-mounted levers fulcrumed to
studs upon plates fixed upon the seat-board D of the cab. m m¹ are arms
formed with the levers lek, respectively. n is a link connecting the outer end of
the arm m with a universal joint n¹ upon the end of a link o; and this link o is
connected at its other end with the extreme lower end of the lever d. p is a bar
connecting together the hinder ends of the levers k¹, and pl is a transverse sluice
in the centre of the bar p. q is a vertical rod passing down inside the back of the
cab, as shewn. The lower end of this rod is cranked, and the bottom of such
cranked part fits within the sluice p¹. The top of the rod is fitted with a handle q¹,
in position to be readily operated by the driver whilst seated at the back of the
cab. As the handle is moved in one direction, the bar p is moved endways in a
direction indicated by the arrow r, carrying with it the back ends of the levers
and . The outer end of the lever m is consequently moved backwards, and so is
therefore the lower end of the lever d, and the chain is consequently pulled in such
direction as to turn the wheel a in the direction to close the door C. Upon the
handle being moved in the reverse direction, the opposite effect is, of course,
produced, that is the door is again opened. Duplicate mechanism is carried within
each side of the cab, except that the chain or cord passes in the reverse direction
relatively around the wheel a on one side to its direction around the wheel a on
the other side, so that both doors may be opened and closed together.
In the position in which the levers are shewn in figure 2, both doors are
wide open. C is that door which underlaps the other door of the pair. 88' are
slots in the ends of the bar p; and in the relative positions of the levers k k¹ and
bar p, as shewn in figure 2, the pins connecting the levers with the bar pass
through the outer ends of the slots. As the bar is moved in the direction of the
arrow, to close the doors, the back end of the lever k is simultaneously moved in
the same direction, and the door C commences to close. After the bar has been
moved sufficiently, in the direction described, to bring the inner end of the slot 8¹
against the pin therethrough, the back end of the lever moves simultaneously
with the bar. A lead is thus given in closing to the door C. Each door is moved
by the mechanism in closing until up to the point when it has a tendency to fall
inwards and close itself. At such point the door C operates through the mechanism
and causes the back end of the lever k to advance more rapidly in the direction of
the arrow 7, until the pin through the slot & comes against the inner end of the slot,
after which the door is held by the mechanism from closing too rapidly. Shortly
after the door C has passed the point at which it has a tendency to fall inwards,
the other door passes its corresponding point, with the effect of moving the pin
through the slot s again rapidly into position against the outer end of the slot,
after which this door also is held by the mechanism from closing too quickly.
It will now be seen that the door C (that is the underlapping door) will close first,
because, after the doors have passed the point in closing at which they have a
tendency to fall inwards, the pin through the slots is at the inner end of the slot,
whereas the other pin is at the outer end of the slot s¹. As the bar p is continued
to be moved in the direction of the arrow r, after the door C has been closed, the
other door is also closed, and the slot s is moved into position with its outer end
against the pin therethrough; so that when both doors have been closed, the pins
through the slots s s¹, respectively, are against the outer ends of the slots. As the
handle q is moved to traverse the bar in the reverse direction to the arrow
open the doors, the reverse action to that already described takes place, as will
now be readily understood, that is to say, the overlapping door is the first to be
opened. The length of the slots 8 st is, of course, made sufficient to allow of the
necessary lead of the underlapping door in closing, and consequently of the over-
lapping door in opening.

Figure 2a illustrates a means for keeping rain, snow, & from driving into the
cab through the hole w (figure 2) in the door pillar through which the chain
passes. This view is a corresponding section to that shewn at figure 2, but only
sufficient of the parts is shewn to make this part of the invention clear, and the

and . Figure 3 is a vertical section through part of the back and seat board of
the cab, and figure 4 is a sectional plan taken on line y y of figure 3, but shewing
only sufficient of the cab to make the application of this modification clear. A¹ is
the back of the cab, and D¹ the seat board, t is a bar corresponding to the bar p
(figures 1 and 2) and u is a snug standing up on the bar t. t is a lever fixed to
a spindle passing through a mounting at the back of the cab, as shewn, and is
jawed at its lower end to embrace the snug u. A pin passes through this jaw to
connect it with the snug, and consequently with the bart; and the hole in the
snug through which the pin passes is slotted vertically to allow of the vibration of
the lever tu¹ is a double-ended pedal mounted on the back end of the spindle,
aforesaid, and in position to be readily operated by the driver whilst seated at the
back of the cab. Upon depressing one end of this pedal the doors are closed, and
upon depressing the other end the doors are opened. A handle may be employed,
if desired, in lieu of the pedal. The bar t is slotted at its ends similarly as the
bar p (figures 1 and 2) is slotted, and for the same purpose.
