COMPLETE SPECIFICATION.
Improvement in Window Sashes.
I CHARLES DENBEIGH of No. 1, Laurel Cottages, Lordship Lane, East Dulwich in
the county of Surrey, Carpenter, 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 improvements in and connected with window sashes, the
improvements consisting in an arrangement by which the present dangerous system
of cleaning the outside of windows by the operation sitting or standing on the window-
sill for this purpose, is altogether abolished.
For the purposes of this description 1 will now refer to the accompanying
drawings, illustrative of my invention in which figure (one) represents a vertical
sectional plan of frame & sashes when in closed position. Figure (2) shows the out-
side elevation of sashes & frame with hinges fixed to sliding sashes & sliding frames.
Figure (3) shows horizontal plan of sashes & frames & also the hinges. A. A. are
the pully stiles of ordinary sash frame. B. B. are the stiles of sliding frame.
C. C. are the stiles of sashes hinged to the sliding stiles B. B. by hinges D. D.
the sash weight cords are attached to sliding stiles of frame B. B. allowing sash and
sliding frame to go up or down as an ordinary sasli.
One half of hinges D. D. being fixed to the stiles of sliding frame B. B. and
the other half of hinges being fixed to stiles of sash C. C. thus rendering the sash
and sliding frame perfect as an ordinary sash, substantially one piece, and the sash
weights which are connected to sliding stiles B. B. over pulleys E. E., to exactly
balance the combined parts B. B. and C. C. with the usual fittings.
As above described the window sashes will work under same conditions as all
ordinary windows, but when the windows are to be cleaned on the outside, the
advantages of my invention becomes apparent, in order to effect this the operator has
only to turn back the ordinary sash fastening on meeting rails of sashes F. F. and
reverse the sash as shown in dotted lines section G. G. (Fig. No. 1.) when the operator
can clean the outside, then turn sash back in proper place and position, slide the
bottom sash up pull top sash down, reverse sash, and clean in the same way as
described with bottom sash.
It will be seen that the equilibrium of the sashes and weights is not at any time
וני.D

page_text: effected, as the weight of sashes will be the same in any position, the sashes and
sliding frames being at all times connected with the hinges will always counter-
balance the weights.
The hinges are so fixed to ensure a weather tight joint when sashes are closed.
The several parts of my invention can be made of iron, brass, steel, wood or any
other known suitable material.
Having now described the nature of my invention and how the same is to be
performed I declare that what I claim is-
The use in combination with the sashes of window frames, the sliding frame and
stiles B. B. and hinges D. D. arranged and operating together in the manner and for
the purposes before described and shown in the annexed drawings.
Dated this Thirteenth day of March 1890.
