I, THOMAS GLOVER LYON, of No. 39, King Street, Cheapside, in the City of
London, Physician, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in hansom cabs by means of which the
ventilation of the interior of the same can be effected and regulated without difficulty
when the front window is in its lowered position. The said improvements are simple
and durable and are of such a nature that they can be applied, with little expense, to
cabs already constructed.
This invention is applicable to hansom cabs having the glass of the front windows
contained within two separate frames, the upper one of which is hinged to the top of
the interior of the vehicle and the lower one is ordinarily either hinged to the bottom
bar of the upper frame so that may fold on to the latter when the window is raised,
or, it is so arranged in connection with the upper frame that when raised by a cord
provided for that purpose, it slides up the back of the upper frame. In the latter case
a loop or guides are pivoted to the lower part of the upper frame. The lower frame
is free to slide up and down between the upper frame and the said loop or guides, and,
when slightly raised, can be turned outwards on the latter. The said lower frame is
arranged in connection with the upper frame in any ordinary manner which will
permit of its being moved at an angle, as hereinafter described, when slightly raised
and will prevent it from becoming disengaged, from the upper frame.
On the inner face of the vehicle immediately above the doors, or door frames,
I arrange a number of grooves or guides and when the lower frame of the window is
lowered into its usual position the sides thereof will enter the inner grooves, thereby
closing the space above the doors. If the person within the vehicle desires to adinit
more air he raises the lower frame until it is free from the grooves, and then turns
it outwards on the hinge or loop until the bottom bar thereof is a sufficient
distance from the tops of the doors when he allows it to descend into the grooves
corresponding with that position, or, the said frame may be guided into the desired
grooves as the window is being lowered.
Dated this third day of July 1888.
VAUGHAN & SON,
Agents for the Applicant,

page_text: I, THOMAS GLOVER LYON, of No. 39, King Street, Cheapside, in the City of
London, Physician, 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 tho
following statement:—
My said invention relates to improvemonts in hansom cabs, by means of which,
the ventilation of the interior of the same can be effected and regulated without
difficulty when the front window is in its lowered position and without danger of
admitting rain.
The said improvements are simple and durable and are of such a nature that they
can be applied with little expense to existing cabs.
The invention is applicable to hansom cabe having the glass of the front windows
contained within two separate frames or sashes, the upper one of which is hinged
to the top of the interior of the vehicle and the lower one of which is ordinarily
either hinged to the bottom bar of the upper frame or sash, so that it may fold on
to the latter when the window is raised, or, in which the lower frame or sash is so
arranged in connection with the upper frame, that, when raised by means of a cord
provided for that purpose. it slides up the back of the upper frame. In the latter case,
guides are fixed to the lower part of the upper frame, and the lower frame is free to
slide up and down between the upper frame and the said guides.
Now, according to my invention, the said lower frame or sash is arranged in
connection with the upper framo in such a manner that it is capable of being raised
or folded out of the way, and, when in its lowered position, of being moved outwards
at an angle, without becoming disconnected from the upper frame and there fixed, as
hereinafior described.
space
On the inner face of each side of the front of the vehicle, immediately above the
doors or door frames, I arrange a number of grooves, guides or recesses, so that when
the lower frame or sash of the window is lowered into its usual position closing the
above the doors, the sides thereof or studs or projections thereon will engage the inner ono
of the group of grooves, guides or recesses and thereby hold the window closed. If,
however, the person within the vehicle desires to admit more air, he can raise the
lower frame until it is free from the grooves, and then turn it outwards until the
bottom har thereof is a sufficient distance from the tops of the doors and allow it to
descend and engage the grooves, guides or recessos corresponding with that position,
or, he may guide the said frame into the desired position as the window is being
lowered by the driver.
Or, if preferred, the studs upon the lower frame or sash may be spring studs, in
which case, they will sump into and out of the grooves, guides or recosses and it
will be unnecessary to raise the lower frame or sash in order to regulate the
dimensions of the ventilating opening.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully to
describe the same,

page_text: Figure 1. represents a longitudinal section of part of a hansom cab, having my
invention applied thoreto.
Figure 2. represents an inside view of part of the front thereof.
Figure 3. represents an outside view of part of the front thereof.
Figure 4. is a sectional side view drawn to an enlarged scale of part thereof.
Figure 5. is a face view.
Figure 6. is a plan thereof.
Figure 7. is a sectional side view of part of the front illustrating a modification.
Figure 8. is a sectional outside view of part of the front thereof, and
Figure 9. is a longitudinal section illustrating the application of my invention to
another class of window.
In the several figures of the drawings, like parts are indicated by similar lettors of
reference.
Referring to Figures 1. to 6. a. represents the body of the cab, and b. b¹ represent
respectively, the upper and lower window frames or sashes which are connected
together at their meeting edges by means of guides & hinged at their lower ends
to the lower part of the upper frame b. and formed to embrace the side edges of
the lower frame or sash and yet permit it to be slidden up and down freely on
the inside of the upper frame b. in order to lower or close the window or to be
folded and raised or opened by means of the cord c. until it assumes the position
shown by the dotted lines in Figure 1. as will be readily understood.
d. represents the ordinary fixed curved guides for guiding the lower frame or sash b¹
into proper position over the top edge of the doors a¹ when lowered by the cord c.
The lower frame or sash ¹ is, by reason of its guides & being hinged to the upper
frame or sash b. capable of being turned on such hinges and moved outwards at an
angle as shown by the dotted lines in Figure 1. and there retained as hereinafter
described.
Upon the inner face a² of each side of the front of the cab, I arrange a number
of grooves, guides or recesses a³ and upon each of the corresponding edges of the
lower frame or sash b¹, I provide a stud or projection 63 so that when the lower
frame or sash b¹ is lowered into its usual position closing the space above the doors a¹
the studs or projections 6 will engage the inner ones of the group of grooves
guides or recesses a and thereby hold the window closed, or the edges of the
Tower sash or frame b' might be caused to engage the grooves, guides or
recesses a³.
If, however, the person within the vehicle desires to admit more air, he can raise
the lower frame 6 by means of the knob b until it is free from the grooves, guides or
recesses a and then turn it outwards upon the hinges of the guides until the bottom
edge thereof is a sufficient distance from the tops of the doors a' to give the required air
space and allows it to descend and engage the grooves, guides or recesses a
corresponding with that position; or, he may guide the lower frame or sash b¹ into
the desired position as the window is being lowered by the driver.
Or, if preferred, the studs or projections & upon the lower sash or frame b¹ may be
spring studs, in which case, they will readily snap into and out of the grooves, guides
or recesses a³ and the lower part of the frame or sash b¹ may be moved in and out
without the necessity for raising it clear of the grooves, guides or recesses a³ in order
to regulate the dimensions of the ventilating opening.
The extreme motion of the lower frame or sash bin an outward direction is limited
by the flanges or stops a' upon the inner side a² of each side of the front of the cab,
but, if a greater range is required the cab front must be built out at that point and the
number of grooves or recesses a³ must be correspondingly increased.
In the modification represented at Figures 7. and 8, which are drawn to an enlarged
scale, a groove a is formed in the side of the cab front to receive the studs or
projections of the frame or sash b' and thereby guide such frame or sash in its
movements, and when employing spring studs or projections 63, they will snap

page_text: into and out of the groove a when tho window is being raised and lowered, but
when employing fixed studs, or projections 6, an opening a indicated by dotted
lines, is formed to allow of the studs entering and leaving that part of the groove at
such times, and the lower part of tho groove a is continued horizontally as shown by
the dotted line to enable the window to be moved in and out as desired.
In the arrangement represented at Figure 9. the upper and lower frames or
sashos b. b are connected together at their meeting edges by means of hinge joints
in such mannor,
that such frames are capable of being folded and raised by means of
the cord c. into the position indicated by the dotted lines as is well understood, hut, in
other respects, the parts are similar to thoso hereinbefore described.
1 would here remark, that I do not confine myself to the precise details of con-
struction herein shown and described as it will be evident that the samo may he
considerably variod without departing from the peculiar character of my invention.
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 :-
1. In a hansom cab, constructing the lower frame or sash of the glass front or
window and the cab front in such a manner, that the lower frame or sash is capable
of being moved outwards at any desired angle within certain limits and there retained,
all in manner substantially as herein shown and described and for the purpose
stated.
2. In a hansom cab of the character referred to in the preceeding claim, constructing
the glass front or window with guides hinged to the lower part of the upper
frame or sash b. to receive and guide the lower frame or sash & in its up and
down movements and yet permit it to be moved outwards at an angle, all in manner
substantially as herein shown und described and for the purpose stated.
3. In a hansom cab, in which the lower frame or sash of the glass front or
window is capable of being moved outwards at an angle, constructing the front of
the cab with grooves, guides or recessos a to receive the lower frame or sash b' or studs
or projections thereon, all in manner substantially as herein shown and described,
and for the purpose stated.
