Improvements in Apparatus for Hanging Window Sashes and
the like.
I, ALEXANDER JAMES, of Church Street, in the City of Wellington, in the
Colony of New Zealand, Joiner, 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:―
The objects of my invention are to provide a method whereby the ordinary sash
weights and pulleys in window sashes and other like apparatus may be dispensed
with, and to provide a simple, effectual, and easily operated apparatus whereby the
sashes can be lifted and lowered with facility, and will remain open in any position
desired, and be so firmly held and guided as to prevent noise from rattling.
My invention is illustrated in the accompanying drawings in which :-
Figure 1 is a front elevation of a pair of ordinary window sashes and frames
with my apparatus attached.
Figure 2 is a front view of a part of one of the sashes and frame with my
apparatus attached, but drawn to a larger scale than in Figure 1.
Figure 3 is an end view of the same.
Figure 4 is a section through the line A-B.
(a) and (a¹) are the window sashes having formed on them tapered grooves or
inclined planes (a) which are (by preference) lined with a piece of steel (a³), see
Figure 2, to prevent wear. These inclined planes are (by preference) made narrow
80 as not to weaken the sash, and are deep at their lower ends and tapered off to
the top of the sash. (b) are rollers which fit into the grooves (a2) and revolve in
bearings (6) formed in the slides (c) which slides fit into and slide in sockets (d)
having flanges (d') which are fastened firmly to the pulley styles by means of the
Screws (d).
(s) are springs fastened firmly at one end to the pulley styles by means of the
screws () and at the other end bearing against the slides (c) carrying the rollers (b)
as shewn in Fig. 4.
(e) are clips clipping the springs (s) by means of the pins (el) and regulating the
pressure of the springs on the slides (c) by means of the screws (e³).
It will be seen from this description of the several parts and by reference to the
drawings that my invention consists in forming inclined grooves (a³) in the sashes,
such grooves being pressed by rollers (6) actuated by springs (s) firmly fastened at
their lower ends to the pulley styles and producing an upward tendency of the sash
proportional to the strength of the springs (s) and the inclination of the inclined
planes; that such pressure is regulated by the screws (e³) to produce the necessary
pressure, and that by these means windows can be raised and lowered with facility
without the use of sash weights and pulleys.
It will be evident that the springs and rollers might be fixed to the sashes and
the inclined planes formed in the frames which contain the sliding sashes, also that
spiral springs may be substituted for the leaf springs shewn, moreover that my
apparatus suitable for sliding shutters and other apparatus acting in a similar
manner to ordinary window sashes.
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. In an apparatus for hanging window sashes and the like, the inclined
planes (a) combined with rollers (6) pressed by springs (8) as and for the purposes

page_text: 2. In an apparatus for hanging window sashes and the like, the inclined
planes (a) rollers (b) and springs (s) combined with clips (e) and regulating
screws (e) as and for the purposes substantially as set forth.
3. In an apparatus for hanging window sashes and the like, the inclined
planes (a2) rollers (6) having slides (c) working in sockets (d) by means of
springs (s) as and for the purposes substantially as set forth.
4. The apparatus for hanging window sashes and the like, substantially as
described herein and illustrated.
