Improvements appertaining to Sliding Windows or Sashes.
I, WALTER WHITLEY of Park Road, Bingley in the County of York,
Manufacturing 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, that is to say :-
It relates to the application of efficient and comparatively inexpensive means to
sliding windows or sashes whereby one sash counterbalances the other and the
coupling parts between the two are so constructed and arranged to be adjusted that
they may be regulated to meet any irregularities or differences in or between the
relative positions of the sashes by which the mounting and fixing-in-position of
these sashes is greatly facilitated, while said coupling parts as also the framework
of the window are made to allow the lower sash to be readily detached or
dislodged.
In the accompanying sheets of drawings which are illustrative of my
invention;
Figs. 1 and 2 are sectional elevations of the framework and sashes forming the
window, the former showing said sashes in their highest and lowest or closed
positions while the latter shows them slightly moved from these positions.
Fig. 3 is a front elevation of a portion of a window, with the upright part
of the staff beading removed so as to show the application of my improved parts
more clearly.
Figs. 4, 5 and 6 are front, edge and end views enlarged scale of my improved
pulley bearings as hereinafter described.
Figs. 7 and 8 are front and end views enlarged scale of a portion of the lower
sash and shows the regulating parts hereinafter described.
Figs. 9 and 10 are front and edge views showing in detail my improvements in
the formation of the framework.
To carry my invention into effect I mount the pulleys a over which the coupling
chains (which I preferably employ although cords, tapes or other flexible
connections may be used) pass from having one of their respective ends b¹ attached
to one sash c while the other end b' is attached to the other sash d in the relative
positions shown so that the said end 61 is fixed to the inner edge c¹ of the outer or
upper sash c, and the end 6' reaches down to be attached centrally over the
vertical bar d¹ of the lower or inner sash d, thus the load of both sashes is
carried in a desirable manner by the coupling chains 6 without necessitating the
cutting away of any great portion of the vertical bar c to the detriment of said
sash c.
The bearings e for the pulleys a are also formed so that the projecting part f
will be in line with and answer the purposes of the dividing laths or parting bead
at the parts where they are situated, as well as forming guides for the chains b
by which means these latter are kept or retained in their proper positions on the
pulleys a.
The fixing of the coupling chains b to the lower sash d is effected by suitably
formed hooks h (or loops 3 as shown by Figs. 11 and 12, may be employed instead
of these hooks h, in which case hooks A³ are fixed on the ends of the chains bas
shown in the said Figs. 11 and 12) which have their elongated ends A' screwed to fit
into nuts or blocks k which are inserted or let into the vertical bars d', by which
means the chains b may be readily detached therefrom whenever desired in order
to allow the sash d to be removed (by and on removing the bead m) from the frame
for cleaning or other purposes.

page_text: On these chains 6 being detached from the lower sash d, the upper sash c may be
allowed to descend or by suitable retaining hooks n fixed in the framework, for the
chains to lay hold of, this sash c may be held in its raised position.
In order that the bead m may be readily detached and yet be firm when in
position, its outer end m' is formed of the wedge shape shown, while a corresponding
indent or opening is made in the end p' of the rigidly fixed bead p. The lower
end m² of the bead m is also formed as shown by Figs. 9 and 10 in order that it
also may be inserted into a suitable opening made in the framework at s by which
means when this bead m is placed in position, the turn button t is all that is
necessary to retain it in said position.
Although throughout all the drawings I have only shown the fixings on one
side of a window, yet I wish it to be understood that they are used on both sides
alike.
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 method of and means for hanging and counterbalancing the sliding
sashes of windows substantially as herein specified.
2. The bearings e formed as described and the pulleys a mounted thereon in
combination with the sliding sashes c and d substantially as herein set forth and
described.
3. The combination of sliding sashes such as that at c and d, flexible coupling
means as the chains b for attachment to both of said sashes, and pulleys as those
at a, with screwed adjusting hooks (or eyelets) as those at h these latter being
mounted and arranged to operate substantially as herein specified.
4. The combination with the detachable sashes of a window, of the bead m
having its outer ends formed as described for fixing it in position substantially as
herein set forth and described.
