PROVISIONAL SPECIFICATION.
Improved Means for Raising and Lowering Windows.
I, ROBERT MARRINER PAINTER, of Penkhull, Stoke-on-Trent, Staffordshire,
Commission Agent, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to improved means for raising and lowering windows in
frames or casements, the invention being especially applicable to the raising and
lowering of railway and other carriage windows.
In accordance with the present improvements, the sash-frame is connected to one
end of a freely extending and collapsing lazy-tong system of levers, the other end of
which is centred or pivoted to the door or window frame at a suitable part thereof,
and such system of levers has extending and opposite movements imparted thereto
by means of a guided rod or equivalent means (to which a relatively small extent of
motion is imparted by hand) projections from which engage with slots formed in the
lazy-tong lever arms next adjacent to the said pivotal connection, in consequence of
which the aforesaid small extent of movement imparted to the said rod or its
equivalent causes a relatively greater extending or opposite movement of the system
of connected levers and a corresponding opening or closing movement of the
connected window.
The said movements of the guided rod or its equivalent may be effected by linking
it to a lever arm on a spindle projecting through the door or window framing and
provided with a spring lever handle in convenient position for use, and such handle
may advantageously work in connection with a notched segment or equivalent means
so that the window may be readily raised or lowered to and set at any desired position
by correspondingly moving the said handle. The movements of the said rod or its
equivalent may, however, be effected by other suitable manually operated means.
The window frame may be fitted with a draught excluder intended to be actuated
by the lever handle by proper connections.

COMPLETE SPECIFICATION.
Improved Means for Raising and Lowering Windows.
I, ROBERT MARRINER PAINTER, of Penkhull, Stoke on Trent, Staffordshire,
Commission Agent, 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 :-
This invention relates to improved means for raising and lowering windows in
frames or casements, the invention being especially applicable to the raising and
lowering of railway and other carriage windows.
On the accompanying drawings
Fig. 1, represents an inside view of a railway carriage door adapted with the
present improvements, part of the lining of the door and part of the improved window
opening and closing mechanism being shown as removed, and the window being
represented as open.
Fig. 2, is a like partial view, representing the window as closed.
Fig. 3, is an elevation of one modification of the hand actuating mechanism.
Fig. 4. is a sectional elevation thereof: and

page_text: Figs. 5 and 6 are like views of another modification thereof.
In accordance with the present improvements, the sash-frame 7, is connected to one
end, as at 8, of a freely extending and collapsing lazy-tong system of levers 9, the
other end of which is centred or pivoted, as at 10, to the door or window frame 11, at
a suitable part thereof, and such system of levers has extending and opposite move-
ments imparted thereto by means of a guided rod 12, or equivalent means and con-
necting lever arms 14, or the like (to which a relatively small extent of motion is
imparted by hand) projections 15 from which arms 14 engage with slots or holes 16,
formed in the lazy-tong lever arms next adjacent to the said pivotal connection 1,
in consequence of which the aforesaid small extent of movement imparted to the said
guided rod or its equivalent causes a relatively greater extending or opposite move-
ment of the system of connected levers 9, and a corresponding opening or closing
movement of the connected window, 7.
The said movements of the rod 12, (which may be guided by a projection 17,
supported by the door frame,) may be effected by linking it, as at 18, to a lever-
arm 19, on a spindle 20, projecting through the door or window framing or lining 21,
and provided with a spring lever handle 22, in convenient position for use, and such
handle may advantageously work in connection with a notched segment 23, or
equivalent means so that the window 7, may be readily raised or lowered to and set
at any desired position by correspondingly moving the said handle. The handle 22,
is pivoted at 24, to a lever arm 25, working with the lever arm 19, and is linked, as
at 26, to a catch 27, guided by bearings 28, and normally kept in gear with the
ratchet 23, by a spring 29. The movements of the said rod or its equivalent may,
however, be effected by other suitable manually operated means, as for example the
arrangement illustrated in Figs. 3 and 4, wherein the rod 12, is not guided but is
directly connected to the lever arm 19, the handle 22, also being directly applied to
the spindle 20, and adapted with a finger pull 30, by which the catch 27, is withdrawn
from the ratchet 23, against the resistance of the spring 29, to permit of the opening
or closing of the window.
The window may be suitably balanced if required, and this may be effected by
giving the extending movement of the lazy-tongs a start by means of a spiral or other
suitable spring attached to the lower centre pin of the device.
The window frame may be fitted with a draught excluder actuated by the lever
handle by proper connections.
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. The hereinbefore described improved means for raising and lowering windows or
sash frames in frames or casements.
2. In combination, in apparatus for raising and lowering windows or sash frames
in frames or casements, a freely extending and collapsing lazy-tong system of levers
opposite end or parts of which are respectively connected to the sash frame and to
the casement, and means substantially such as those herein before described to which a
relatively small extent of motion is imparted by hand for extending and collapsing
such system of levers.
