COMPLETE SPECIFICATION.
Improvements connected with Reversible Sashes and in Sash
Frames therefor.
I, FREDERICK WILLIAM WHITE, of The Vestry Hall, Mount Street,
Grosvenor Square, London, Accountant, 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 certain improvements connected with window sashes
which are pivoted in sliding styles, and capable of being raised, and lowered, and
reversed for cleaning purposes from inside a room, the pivots being simple screws,
on the plain shoulders of which, the sashes can turn. I employ plate springs
preferably on one side only to keep the sashes taut, the springs having sufficient
strength to hold either sash at the position to which it is opened, whereby I
dispense with the usual cords, weights, and pullies.
My invention is clearly represented in the annexed drawings.
Figure 1 a front elevation of sufficient of a pair of sliding sashes with the front
side or facing board removed. Figure 2 a sectional plan of same.
Figure 3 is a vertical section indicating an additional bottom sill rail rabbetted
for the lower sash rail to lodge in for making a close joint at that part.
Figure 4 shows the two sashes set at an angle, they are however capable of
being completely turned over or reversed, either from the upper part of the frame,
or from the lower part, as desired.
A is the lower sash. B the upper sash both pivoted to sliding side strips B', B',
of the same length, so that each can be moved up or down as a single body.
C, C, are liners bearing against the sliding strips B¹, B', under the pressure of
the springs D, D, which are fastened to the side uprights of the frames. These
springs are preferably on one side only, but they may be on both sides, if on one
side only, as I prefer, the sashes are easily put in place after the removal of the
bead on the opposite side by simply compressing the springs, and slewing the
opposite sides of the sashes in, and then refixing the bead.
I purpose employing a socket tube E on the plain shoulder of each screw pivot
for it to turn in, the thread of the screws, having sufficient grip in the sashes when
screwed home as to prevent them becoming loose. The upper sash, when lowered,
can be reversed with facility.
F is the additional sill rail on the ordinary sill rail but it may be in one piece as
the sill rail. By this addition, the sashes are so made that the upper sash when
lowered goes below the addition and clear of the raised lower sash to enable it
i.e. the lowered upper sash to be reversed.
By the employment of the springs in the manner described, the sashes are kept
from rattling and are held securely in any position at which they may be placed,
the additional sill rail when the lower sash is in touch obviates the entrance of rain
water, or any bubbling action during storms.
I am aware that sliding sashes have already been fitted to sliding side strips, and
that such sashes have been made reversible, therefore I make no claim to the
principle of making sliding sashes reversible, but
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the saine is to be performed I declare that what I
claim is :-
The combination of appliances, or the means hereinbefore set forth, and con-
sisting of simple screw pivots, sliding side strips, the pressure liners, springs, and

page_text: additional bottom or sill rail, all acting in the manner, and for the purposes
described.
2. In sashes having a reversible action, the employment of a bottom or sill rail,
or its equivalent above the level of the ordinary sill, as hereinbefore described for
the purpose set forth, and substantially as shown.
