Improved Means or Apparatus for Raising, Lowering, and Retaining
in any desired position Carriage or other Windows and the
like, and for Excluding Draughts therefrom.
1, JOHN COLMAN of Beachenhurst Lincoln Road Acocks Green in the
County of Warwick Gentleman, do hereby declare the nature of this invention
to be as follows:-
-
This invention consists of an arrangement constructed upon the lazy tong
principle for raising & lowering windows.
Attached to the bottom of the door within the lower part of the same & again to
the bottom frame of the window is the lazy tong arrangement, rizt. strips of metal
or other suitable material crossing one another & being rivetted together at the
ends & in the centre in the usual manner to allow of opening & shutting.
Connected to the lazy tongs wherever found most convenient by means of a
crank piece is an angular piece of metal forming a lever arm this is hinged or
pivotted at its elbow to a bracket piece from the door whereon the lever works.
The one arm of the angle iron to which the handle is connected is extended up
the door. Two horizontal bars cross the door at the bottom of the window opening,
a sufficient distance each to each to allow the neck of the handle to pass between,
the lower bar has indents or slots where required for the neck of the handle to take
into to regulate the height of the window.
The handle connection with the lever is made to slide onu with the other so as to
lengthen & shorten in its passage across the door, when the window is being raised.
By drawing the handle along the bars the lever is actuated and the lazy tong
arrangement expanded the window being thereby raised, the height of the same
can be determined by the indents or slots on the lower bar whichever the handle
may be rested in. The reverse action of the handle & lever obviously will lower
the window the lazy tongs being thereby contracted.
When desired I may use weights & springs to assist the lever in its work & to
take off some of the weight from the lever, thereby reducing friction.
In connection with my improvements I use an arrangement for excluding
draught & weather, this consists of a horizontal strip of metal or any suitable
material which is pivotted on the outside of the door frame in such a manner that
upon the window being raised it will bear against the frame & when the window is
full up it will tilt underneath the bottom of the same & be held & so form a
weathering or drip, the window upon being lowered causes the strip to turn on its
pivots & allows the window to pass down the door.

Improved Means or Apparatus for Raising, Lowering, and Retaining
in any desired position Carriage or other Windows and the
like, and for Excluding Draughts therefrom.
I, JOHN COLMAN of Beachenhurst Lincoln Road Acocks Green in the County
of Warwick Gentleman 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 to the figures and letters shewn thereon:-
Figure 1 is a sectional elevation of my improvements as applied to a carriage
door shewing the window lowered or open.
Figure 2 is a sectional elevation of same shewing the window raised or closed.
My invention consists of an arrangement of parts constructed upon the lazy tong
principle for raising and lowering the windows of carriages and such like and also
for retaining the same in position.
Attached to the bottom frame of the door A, within the lower part of the same
and also to the lower frame of the window B is an arrangement of cross bars or
strips of metal upon the lazy tong principle C.
These cross bars or strips of metal (or other suitable material) C, cross_one
another and are rivetted together at their ends D, and also in their centres E, to
allow of being expanded or contracted.
Connected to the lazy tong apparatus wherever found most convenient by means
of a crank piece F is an angular piece of metal of any desired thickness which
forms a lever arm G, G¹, this lever arm is hinged pivotted or otherwise suitably
connected at its elbow G", to a bracket piece H attached to the frame work of the
door and window, whereon the lever arm G G¹, has its bearing and works. The
oue arin G of the angle iron is extended up the door and is connected to a tubular
(or other) piece of metal I, which is made to slide or telescope within the tubular
lever J, so as to lengthen and shorten in its passage across the window or door,
when the window B is being raised or lowered.
Two horizontal bars K K³, cross the door at the base of the window opening B',
a sufficient distance being allowed between each bar to allow of the neck of the
handle L passing between same, the lower bar K is provided with indents or
slots M at certain distances for the neck of the handle L to obtain a seating in
when required to adjust the window at any given height.
OPERATION.
Given that the window B is lowered and it is required to raise same.
By drawing the handle L horizontally along the bars K, K', the tubular rods I J
of the lever, telescope or shorten in their passage the tubular rod I being
immediately connected to the arm piece G¹ of the angle iron or lever arm causes
the same to pivot or turn at its elbow G", and thus actuate the lazy tong move-
ment C, whereby the same is expanded the window being then raised as shewn in
Fig. 2. The height it is desired to raise the window is determined by the stoppage
of the handle in either of the indents or slots M.
The window upon being raised its full height lodges upon the intermediate cross
bar or sill of the door B or will be retained in place by the vertical position of
the lever attachment and the handle within one of the slots on the lower horizontal
crossbar.
The reverse or backward action of the handle L and lever connection obviously
lowers the window as the lazy tong movement will become contracted as shewn
in Fig. 1.
I
hin and

page_text: to assist the lever arrangement in its work and also to take off some of the weight
from the lever in order to reduce possible friction but as a rule I prefer the method
illustrated.
I may mention in connection with my improvements, I can when needful use an
arrangement for excluding draughts, and bad weather, which consists of a
horizontal strip or plate of metal or other suitable material, this strip or plate will
be pivotted on the outside of the door frame in such a manner that upon the
window being raised it will bear against the frame and when the window is closed
up it will tilt underneath the bottom of the same and be held in place by the
window and so form a weathering or drip.
The window upon being lowered causes the strip or plate to turn on its pivots
and allow the window to pass down the door.
I have not illustrated the above method of weathering or drip as usually I prefer
to dispense with the same, and merely raise the window by my improved method
described in the first part of this Specification.
I wish it to be understood that I do not confine myself to the precise details
herein described as I may modify or vary the same where occasion may require
without departing from the general principle of this my invention.
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 improved means or apparatus consisting of the general combination and
arrangement of parts or any mere equivalents thereof for raising lowering and
retaining in any desired position carriage or other windows, shutters, and the like
substantially as herein more fully described and illustrated.
