I, FERDINAND BOSSHARDT of the firm of Bosshardt and Grant Mechanical &
Consulting Engineers and Patent Solicitors of 24 & 32 Bulls Head Exchange
Chambers Market Place, Manchester in the County of Lancaster, do hereby declare
the nature of my invention for "IMPROVEMENTS IN APPLIANCES FOR HOLDING
RAILWAY, CARRIAGE OR OTHER WINDOWS IN ANY DESIRED POSITION," which
has been communicated to me from abroad by Edwin Long, of Rawal Pindu
(Punjab) India, Carriage Foreman, to be as follows:-
My invention relates to improvements in appliances for holding railway carriage
or other windows such as cabs, omnibuses or the windows of buildings, in any
desired position and has for its object to produce an appliance which can be adapted
to existing windows without altering the frames and which is not subject to repairs
and cheaper than those in use at present.
The improvements consist in providing one or both sides of the window frame,
which slide in the recessed part of the sash frame with one or more springs of a
half elliptic shape and flat in section, which spring or springs press against the
recessed part of the sash frame, and thus holding the window in any desired
position when raised or lowered.
This spring or springs I provide with one or more anti-friction pullies which run
in the recessed part of the sash frame.
The said spring or springs are slightly imbedded in the frame of the window
and attached thereto by means of screws or pins which pass through a short slot
formed in each end of the said spring which slots allow the spring to be depressed
when the window is put into the recessed part of the sash frame.
The window is provided at its top with a nob by means of which it can be
raised and lowered & if found necessary the recessed part of the sash frame on

page_text: which the anti-friction pulley or pullies run, may be covered with india-rubber in
order to give the anti-friction pulley more bite and make a good joint.
By these means I am enabled to dispense with the ordinary strap and stud used
for holding the windows in carriages, and with the balance weights cords and
pulley in case of buildings.
COMPLETE SPECIFICATION.
Improvements in Appliances for Holding Railway Carriage or 1
other Windows in any Desired Position.
I, FERDINAND BOSSHARDT, of the firm of Bosshardt & Grant of 24 & 32 Bulls
Head, Exchange Chambers Market Place Manchester in the County of Lancaster,
Mechanical & Consulting Engineer & Patent Solicitor, do hereby declare the nature
of this invention, which has been communicated to me from abroad by Edwin
Long of Rawal Pindu (Punjab) India, Carriage Foreman, and 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 improvements in appliances for holding railway carriage
or other windows, such as cabs, omnibuses, or the windows of buildings, in any
desired position and has for its object to produce an appliance which can be adapted
to existing windows, without altering the frames, and which is not subject to
repairs, and cheaper than those in use at present.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference, indicating
like parts in the various figures.
Fig. 1 is a front view. of a railway carriage window.
Fig. 2 is a view of the window separately, provided with my improved appliance,
& Figs. 3 & 4 a front & side view respectively.
In carrying out my invention I provide one or both sides of the window frame a,
which slide in the recessed part of the sash frame b with one or more springs c,
of a half elliptic shape and flat in section, which spring or springs press against
the recessed part of the sash frame b and thus holding the window in any desired
position when raised or lowered.
This spring or springs I provide with one or more anti-friction pullies d, which
run in the recessed part of the sash frame b..
The said spring or springs are slightly imbedded in the frame of the window a
and attached thereto by means of screws or pins e which pass through a short

page_text: slot f formed in each end of the said spring c which slots allow the spring to be
depressed when the window is put into the recessed part of the sash frame b.
The window a is provided at its top with a knob y, by means of which it can
be raised and lowered, and if found necessary, the recessed part of the sash frame
on which the anti-friction pulley or pullies d, run, may be covered with india-
rubber h, in order to give the anti-friction pulley more bite and make a good joint.
By these means I am enabled to dispense with the ordinary strap and stud used
for holding the windows in carriages, and with the balance weights, cords and
pulley, in case of buildings.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
•
Providing railway carriage or other windows with, and holding same in any
required position by, one or more half elliptical springs furnished with one or
more anti-friction pullies substantially as described and illustrated in the accom-
panying specification and drawings.
