Improvements in Hanging Window Sashes.
JAMES GEORGE CROWE and GEORGE JAMES CORDING both of 27 Gloucester
Street London W.C. Builders do hereby declare the nature of this invention to
be as follows:-
Our invention relates to a method of lifting or lowering sashes of windows we
do this by means of a spring coiled within a drum or barrel attached to a suitable
bracket for fixing to any ordinary window sash a sash cord or wire is wound round
this drum a sufficient number of times necessary to properly balance the weight of
the sash to be lifted or lowered. The end of this cord is secured to the sash frain
by means of a stud. We intend to fix one to each end of the meeting rail or side
of top and bottom sashes, thus doing away with ordinary pulleys, sash weights and
boxings. We construct our apparatus of any suitable metal the drum with an
internal coiled spring or springs secured to a spindle with a rachet and pawl or any
other suitable catch, with an arrangement to increase the tension of the springs by
key or otherwise so as to suit or balance the weight of the window sash to be lifted
or lowered.
In combination and attached to our improvement we apply a bolt or
pin on cach side of the bottom sash, the upper sash having holes at stated intervals
to meet the bolts or pins, thus preventing any possibility of opening from the
outside.

JAMES GEORGE CROWE and GEORGE JAMES CORDING of 27 Gloucester
Street London W.C. Builders 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 :-
Our invention relates to a method of hanging or balancing window sashes without
the aid of ordinary pulleys, sash weights and boxings, to attain this we use a coiled
spring within a drum or barrel attached to a suitable bracket and fixed to any
ordinary window sash, around the drum or barrel we wind or coil a cord or wire
long enough to equal the travel of the window when raised or lowered. The
tension of the coiled spring to balance the weight of the window is managed by
meaus of a rachet and pawl with a key for adjustment. To keep the window sash
in any required position we apply a bolt or pin attached to the drum bracket with
holes at intervals in the frame to meet the bolt or pin. In describing the
drawings
Fig. 1. is a part section half size of a window sash, showing sash frame or
meeting rail B with drum or barrel D encased in frame and fitted and screwed
to sash frame B. The drum D containing spring is supported on spindle A to

page_text: which is attached rachet and pawl P. The cord E is coiled round drum Da
sufficient number of times to equal travel of sash to which it is secured. The pin
or bolt J works in a socket or slide L with or without a spring to hold it in
position.
Fig. 2 is a part side section of sash and frame showing drum D coiled with
cord E, bolt or pin J and eye H.
Fig. 3, shows eye H with hole K into which bolt or pin J fits at stated intervals
in the frame.
Fig. 4 illustrates coiled spring M to balance weight of sashes as heretofore
described.
Having now particularly described the nature of our invention and in what
manner the same is to be performed we declare that what we claim is :
1. Balancing window sashes by means of drum D and spring M encased in
frame with cord E attached substantially as described.
2. Attachment of boit or pin J to frame to fit into holes K in frame
substantially as described.
