Improvements in the Method of and Apparatus for Hanging Window
Sashes, and such like Purposes.
I, WILLIAM JAMES HOYLE RICHARDS of Toothill Street Lewisham a suburb
of Sydney, in the Colony of New South Wales, Ironmoulder, 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: —
My improved frictional buffer grip has for its object the doing away
with sash weights, sash cords and pulleys now in general use to raise and lower
window sashes, and to provide a substitute therefor which will also prevent
window sashes from rattling at any time, and save the cost of the weights, cords
and rollers. My invention is similar in action to a buffer used on railway carriages
and trucks and contains a bush, a spiral spring and a buffer. To more clearly
explain my meaning I now refer to the accompanying sheet of drawings:
Figure 1 is a sectional view of my buffer grip fixed in window sash, showing
buffer against the stile of the window frame, in which A is the bush, C spiral
spring, D stud, B hollow buffer.
Figure 2 is a similar view to Figure 1 but showing the buffer solid and resting
on spiral spring.
The bush is a round tube (or casing) made of any suitable metal (holding a
spiral spring) sufficiently large to admit the buffer, and is countersunk into the
window sash on both sides at any approved position. The spiral spring (made of
any suitable metal) is placed inside the bush, and is of about equal length #o
the depth of the bush, and so that when the buffer is placed over the spring it
requires force to push the buffer into the bush The force required will be regulated
by the strength of spring used. A stud can be fixed inside bottom of bush if
necessary to form a seat or guide for spiral spring and in very large window
sashes it might be an advantage to use them. The buffer is similar in shape to
a copper rivet, but hollow (with a solid head) and of such size as to fit or telescope
into the bush freely, and over (covering) the spiral spring as in Figure 1 of my
drawing or it can be made with the buffer shank solid and resting on top of
spring as shown in Figure 2 of my drawings. The strength of the spiral spring
will be made to equalise or counteract the weight of the window sash, just as
different sized sash weights are now used for different weighted window
sashes. My improved window sash frictional buffer grip will be made
in various sizes (and various strengths of spiral springs) to suit various
sized window sashes, and can be made of brass or any other suitable
metal. The buffer of my improved window sash frictional buffer grip always
forcing against the stiles will hold the window sash in position until force is used
to raise or lower the said window sash, and it will be understood that my buffer
always forcing against the stiles of the window frame, will stop all rattling of
window sash at all times.

page_text: 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. A fractional buffer grip for holding window sashes and the like at the
required height without the use of counterweights and prevent their rattling,
consisting of a bush such as A in which is placed a spiral spring, and a buffer such
such as B substantially as described.
2. The combination with a sliding window sash, of a bush such as A in which
is placed a buffer such as B, and a spiral spring so arranged as to press the buffer
against the stile or frames of the window, to hold the sash in any required position
by frictional contact substanially as described.
