COMPLETE SPECIFICATION.
Improvements in Window Sash Holders.
We, WINFIELD SCOTT PETTIT, Carpenter of Hammonton, Atlantic County, DAVID
REED PETTIT, Carpenter, of Haleyville, Cumberland County and EDWIN DEVAUL
SUTTON, Farmer of Mauricetown, Cumberland County, all of the State of New Jersey,
one of the United States of America, 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 fixtures or attachments for window
sashes to provide a frictional contact with the frame sufficient to support the sashes
without requiring the use of the ordinary counterbalancing weights, stops, catches, or
other similar devices for holding sashes.
Having the above ends in view the invention consists in providing the side rails of
the upper and lower sashes with flat springs secured in recesses therein, so that the
free ends will project in opposite directions, and antifriction rollers carried by said
free ends of the springs, as will be hereinafter fully set forth and specifically pointed
in the claims.
In the accompanying drawings forming part of this specification,
Figure 1 is a front elevation showing the application of the invention, parts of the
window frame and sashes being broken away to show the flat springs that show the
frictional contact.
Figure 2 is a side view looking at the outer edge of one of the side rails with the
flat spring and parts carried thereby in place, and
Figure 3 is a detail view of one of the anti-frictional rollers and frames in which it
is supported.
Referring to the drawings by numerals, 1 designates the window frame or casing
which is constructed in the usual manner to present the parting bead and
inner and outer beads between which the sashes 2-2 slide. The upper and lower
sashes are each provided with a set of the improved friction devices which are applied
to the outer edge of each side rail at the upper and lower portions thereof, as
hereinafter described.
The outer edge of each side rail 3 is provided at its upper and lower ends with
vertical recesses 4 of a length and depth sufficient to receive the friction device
hereinafter described. Within the recesses 4 are seated or rigidly secured a flat
spring 5, said spring being attached to the sash at one end and is curved outwardly
to bring the free end normally a distance beyond the side rails. To the outer or free
ends of the flat springs 5 are pivoted or swiveled brackets or frames 6 presenting ears
which are pierced to form bearings for anti-friction rollers 7. It will be noted that
the flat springs 5 which carry the anti-friction rollers are attached to the side rails, so
that they will extend in opposite directions with respect to each other. It will also
be noted that the bottom of the recesses in which the flat springs are located is
inclined downward from the inner to the outer end thereof, so that when the said
springs are forced inward the rollers will be brought within the rails and permit the
sashes to fit snugly between the side pieces of the window frame.

page_text: By providing window sashes with the friction devices constructed as herein shown
and described, the spring members or plates 5 will bring the rollers in contact with
the window frame with sufficient force to support the sash in any adjusted position,
the strength of the springs depending upon the size and weight of the sashes. It will
also be observed that by having the rollers carrying frames pivoted to the flat springs,
the said rollers may accommodate themselves in their engagement with the window
frame and thereby prevent binding. The anti-friction rollers also provide for easily
raising and lowering the sashes, but are forced in engagement with the frame with
sufficient pressure to hold the sashes.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what is claimed is:
1. A sash holder comprising flat springs secured to the outer edges of the side
rails, and friction rollers carried at the outer or free end of the springs, substantially
as shown and for the purpose set forth.
2. A sash holder comprising flat springs secured to the outer edges of the side
rails of the sash so that their free ends will project outward therefrom, and rollers
supported in frames which are swiveled to the outer ends of the springs, substantially
as shown and for the purpose set forth.
3. In a sash holder, the combination with the side rails having recesses in their
outer ends, the bottom of said recesses being inclined downward from one end to the
other, of flat springs secured at one end in the shallow end of the recesses and
curved to project beyond the sash, roller frames pivoted to the free ends of the flat
springs and presenting ears, which are pierced transversely and rollers located in said
frames, substantially as shown and for the purpose set forth.
