COMPLETE SPECIFICATION.
Improvements in Windows.
I, RICHARD LEWIS BROWN, of Salisbury, in the County of Rowan, in the State of
North Carolina, United States of America, Jeweller, 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 new and useful improvements in windows. The
novelty resides in the peculiar combination, construction, arrangement and adaptation
of parts all as more fully hereinafter described, shown in the drawings and then
particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, form a part of this specification and in which
Figure 1 is a front elevation of a window provided with my improvement.
Figure 2 is a vertical section.
Figure 3 is an enlarged section through the drums.
Like letters of reference indicate like parts in the several views.
Referring now to the details of the drawings by letter, A designates the window
frame and B the sash mounted to slide therein in the usual manner. C is a chain
or cord having one end secured to or connected with the sash in any suitable
manner, in this instance being shown as connected to the centre of a spring bar C¹
attached at its ends to the upper edge of the sash and at the other end is wound
around and attached to a drum or curved roller D carried by a shaft d mounted
in the bracket D¹ secured in the recess in the frame at the upper end of the sash.
The shaft carries a ratchet c which engages a pawl d¹ mounted on the bracket and
adapted to hold the same against retrograde movement.
The end of the shaft is extended and adapted to receive a key or other imple-
ment by which the spring may be wound up when desired, the spring being
connected with the shaft and arranged within the drum or roller as indicated.
The sash at one edge which works in the groove in the frame is provided with
a bar G which is toothed or racked upon one face and screwed to the sash extending
from bottom to top; and connected with the groove in which the sash runs, is an
arm H pivotally mounted as at h with its upper end formed into a hook h¹ to
engage the rack or teeth of the bar on the sash and its lower end has connected
therewith a push pin or button I working loosely through an opening in the frame
and the spring J is arranged to act upon its arm to keep it normally in contact
with the rack bar.
As the sash is pulled downward against the tension of the spring in the roller
or drum, the rack bar moves over the pawl or hook on the end of said arm and
holds the window in any adjusted position. When it is desired to raise the window,
it is necessary only to push upon the push pin or button when its lower end is pushed
inward and its upper hooked end outward away from its engagement with the rack
bar and the spring connected with the cord or chain quickly draws the same
upward into its open position.
L are side arm springs fastened to the outside of the sash and work between
the sash and the strapping. This serves to make the window run easy and keep it
pressed against the inside guide or strip and make the windows dust proof, which is
especially desirable in car windows.
It will be understood that a similar arrangement reversely arranged may be used

page_text: in connection with the upper sash and that various other modifications in details may
be resorted to without departing from the spirit of the invention or sacrificing any
of its advantages.
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 :
The combination with a sliding window, of a spring bar secured to the upper end
of the sash, a chain or cord connected with said bar and a spring drum around which
said chain or cord is wound and to which one end is attached, substantially as
described.
Dated this 29th day of September 1896.
