3 Claims.
My invention relates to improvements in win
dow sash holders which are adapted to hold a
sash in any desired position in the window frame
without requiring the use of the usual counter
An object of my invention is to provide a holder
of the class described which is economical to
manufacture, easy to install and highly ei?cient
in its operation.
A further object of my invention is to provide
such a holder which is adapted to hold the sash
in frictional engagement with the window frame,
by means of a roller which has a spring member
co-operating therewith to force said roller in en
15 gagement with the said frame and to apply a
braking action to said roller against the rotation
thereof which, in addition to the friction between
the sash and the frame, is su?icient to- support
the weight of said sash.
Further objects of my invention will be clearly
understood from the following description and
from the accompanying drawing in which:
Figure 1 is a front view in elevation of a win
dow frame and sash partly broken away to illus
25 trate the application of my invention.
Figure 2 is a front view in central vertical
section, on an enlarged scale, showing a portion
of a window sash and frame and my improved
holder attached thereto.
Figure 3 is a side view of the holder in elevation.
Figure 4 is a top view of said holder.
As shown in the drawing, the numeral 5 de
notes a window frame of usual construction, 6 an
upper, and l a lower window sash each having
35 formed therein recesses: 8 in the side rail thereof
within which recesses my improved holder is con
The said holder comprises a U-shaped frame
having a base 9, and side members it} in which
slots H are provided. A roller i2 is mounted
between the side members it and positioned
therein by means of a shaft 63 extending thru.
said roller and projecting into said slots. This
shaft is ?tted loosely in the roller l2 and in the
45 slots I I so that, when the holder is to be assem
bled, it is simply necessary to place the spring
M in position and the roller it against the curved
portion l5 and forced inwardly. The shaft i3
is then inserted thru one of the slots H, to the
50 position shown in the drawing, and pressure on
the roller‘ is released causing the shaft to be forced
against the end of the slots. When the holder is
in position within the recesses 8 in the sash, the
shaft will be retained against lateral movement
55 in said holder by the side walls of the recesses 8,
(Cl. 292-75)
which recesses are of a width just slightly greater
than the width of the holder frame, thus
providing simple and inexpensive means of as
sembling the holder and retaining the shaft in
its proper position. A friction and thrust spring 5
It is positioned between the said roller and the
bottom Q of the frame. This spring has a curved
portion l5 conforming with the periphery of the
roller and the said spring acts: to press the roller
outwardly in engagement with the window frame 10
5 and also, by means of such pressure, to apply
a braking action against the rotation of the roller.
The said curved portion 55 also acts to retain the
spring member in its proper position with rela
tion to the roller.
My improved holder is attached to the sash by
means of screws it which project thru screw
holes H in the bottom of the frame. This pro
vides a convenient and simple manner for attach
ing the holder.
In the operation of my improved holder, the
spring member it acts to force the roller i2
against the frame 5. In this manner the opposite
side of the window sash is held in frictional en
gagement with the window frame. When the 25
sash is moved to any desired position within the
window frame, the friction between the opposite
side of the sash and the frame and the friction
applied to the roller by the curved portion E5 of
the spring member M is sufficient to retain the 30
sash in any desired position.
It is pointed out that in some cases where the
window sash is of a particularly heavy construc
tion, the friction between the sash and the frame
alone will not be sufficient to retain the sash in its 35
desired position but that with the addition of the
braking action applied to the roller i2, sufficient
friction is provided on both sides of the sash
against the window frame to retain a sash of any
practical weight in any desired position.
I claim:
1. A window sash holder of the character de
scribed comprising a U-shaped frame having an
elongated base portion which is straight in cross
section, side members bent upwardly from said 45
base portion and integral therewith, a roller slid
ably mounted in said side members for holding
the sash in frictional engagement with a window
frame and single means consisting of a spring
member having its ends slidable on the said base 50
portion for applying both lateral yielding pres
sure to said roller and frictional resistance
against rotation thereof.
2. A holder of the character described com
prising a U-shaped frame having an elongated 55
base portion which is straight in cross section, a
roller movably mounted in said frame, and a
W-shaped spring member having its ends in slid
ing contact with the base of said frame and the
center portion thereof in contact with the pe
riphery of said roller to both force said roller out
wardly and to apply a frictional braking action
on the periphery thereof against its rotation.
3. In combination with a sash having an open
members extending upwardly from said base por
tion and integral therewith, a roller movably
mounted in said holder between said side mem
bers, a spring located between said roller and said
base portion and in contact with the periphery of
said roller and the surface of said base portion;
said holder being secured to said sash with the
base portion thereof against the bottom of said
recess and secured thereto.

having a substantially straight base portion, side
