page_text: :I, JAMES ALLEN HASKETT, residing at Parsons, in the County of Labette,
State of Kansas, United States of America, Farmer do hereby declare the nature
of this invention and in what manner the same is to be performed, to bo particularly
described and ascertained in and by the following statement :-
The object of this invention is to provide an improved device for preventing the
rattling of window sashes, and at the same time to provide means whereby the sash
may be easily raised and lowered, and prevented from becoming fast in the
frame.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a front view of a portion of a window frame and a sash mounted
therein, parts of said frame and said sash being broken away to better show the
construction, and,
Fig. 2, a section on the line 2, 2.
In the drawing forming parts of this specification, A, represents a part of the
frame of a window and B, a part of a sash mounted therein; and the frame A, is
provided with the usual strips or beads a, between which the sash is placed and in
my improvement, I form on the frame, or secure thereto between said beads or
strips a, a vertical or longitudinal bead or rib C, and in the sash adjacent thereto is
a corresponding groove D.
I also form in the frame of the sash, chainbers or cavities E, said chambors or
cavities being preferably arranged near the upper and lower ends of the sash, and
mounted in said chambers or cavities are rollers F, which are adapted to bear upon
the bead or rib C.
One of Baid rollers F, is mounted on or connected with a lever G, which is
pivotally supported in the chamber E, in which said roller is placed, and I also
provide a spring H, which is secured at the back of said chamber and which is
adapted to bear on the free end of said lever so as to force the same outwardly, and
in this case the roller F, is yieldingly supported as will be readily understood; and
the pressuro thereof on the bead or rib C, will be regulated by the strength or
pressure of the spring H.
It will be understood that each side of the sash B, and the frame A, are
CODstructed as herein shown and described, or in other words the sash B, is provided
with the rollers F, at each side thereof, and it will thus be seen that the sash is held
in position by the beads or stripes a, and the bead or rib C, in the frame and the
corresponding groove D, in the sash, and that the rollers F, are so mounted as to
bear upon said bead or rib at all times, and thus prevent the sash from becoming
locked in position, and said rollers may be composed of rubber if desired, and soft
rubber will probably be found preferable to other material.
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 combination with a window sash, of two rollers which are mounted in
Buitable chambers formed therein, said rollers being adapted to bear upon the

page_text: frame of the window at each side of the sash, substantially as shown and
described..
2. A window sasli, provided at its opposite sides with suitable chambers which
are formed therein, and which open outwardly, and rollers which are mounted in
said chambers, and which are adapted to bear on vertical beads or ribs formed
on the adjacent sides of the frame of the window, substantially as shown and
described:
3. A window sash, provided at its opposite sides with suitable chambers which
are formed therein, and which open outwardly, and rollers which are mounted in
said chambers, and which are adapted to bear on vertical beads or ribs formed on
the adjacent sides of the frame of the window, one of said rollers on each side of
the sash being supported by a spring operated lever, substantially as shown and
described.
