only this one function of forming a means for
adjusting the position of a member within a frame
and neither prevents rattling, which is usually
found in all such systems, nor does it serve as
a weather stripping in such a case as when a sash
is mounted in a window frame. Among the sev
eral objects of this invention are to provide de~

Referring now to the drawings in detail, there

weight of the member and, of necessity, are
f
‘As conducive to a clearer understanding of
certain features of this invention, it might here
be pointed out that previous methods for holding
a member at any desired position upon a track
within a frame have been accompanied by ex—
cessive cost and ineffectiveness of result. Many
of these devices use weights to counterbalance the
(Figure 3) which extends for the length of the
side 22 of the sash 2i and is rectangular in cross
section. The width of this rectangle preferably
is a great deal smaller than the length which is
the width of the stile H between the side l5 of 50
the guide strip Ill and the side iii of the cover
board if! such as is usually found in constructions
of this type.
I
Within this space‘ 23 and preferably extending
longitudinally between the top portion l2 and the
2,122,553
2 ,
sill l3 and in the track within which the sash
2| slides, I place a resilient strip 24 preferably
constructed of metal such as stainless steel.
Preferably this strip is concave in cross section
having its convex side toward the side 22 of the
sash 2| and between its two edges 25 and 26 hav
ing less length in crosssection than the space
between the guide strip H and the cover board
I8. Preferably the width in cross section of
10 this strip when positioned upon the stile II is
sufficiently greater than the width of the cross
section of the space 23 so that the strip 24 will
be compressed by the sash side 22 against the
stile H and exert a resilient force against the‘
15 side of the sash.
Preferably, the inner edge 25 of strip 24 is
turned upwardly away from the stile to form a
lip 21!. This prevents friction between this edge
of the strip and the stile when the strip is com
20 pressed by the side 22. The opposite edge 26
of the strip 24 is preferably secured to the stile
by any suitable means, as by a wedge shaped nail
28. If this type of nail is used and the strip
is not punched for the nails, the edges |'| im
25 mediately surrounding the nail as it is driven
through the metal will be bent inwardly (Figure
3) and into the stile forming a very secure con
nection. These nails 28 would be driven through
the strip 24 at suitable intervals (Figure 2) to
30 hold the edge of the strip securely against the
stile. Thus, I have provided a resilient strip pref
erably concave and constructed of resilient sheet
metal capable of being attached to the stile H
of a window frame and lying in the track in
35 which the sash 2i slides. Also this strip 24 is
su?ciently concave as to be compressed by the
side of the sash 2| when it is in position thus ex
erting a resilient force against the side 22 of
sash 2| holding the sash in any desired position
upon the tracks in the frame.
,
Immediately below the edge of sides 22 the
compressing force exerted by the sash 2| upon
the resilient strip will be released and the strip
will resiliently stand out forming stops 29. These
45 stops 28 will always be immediately below the
lower edges of the sides 22 wherever the sash 2|
may be placed within the frame I0 and there
fore will form a second means for holding the
window in any desired position within the frame.
The strips 24 which I have thus placed be
50
tween the sides of the sash 2| and the stile II
also form a very effective weather stripping. As
the strip is attached to the stile II, a tight con
nection will be formed between the two, and
55 when the strip 24 is compressed by the sash 2|
the strip will exert a constant resilient force both
against the stile H and the side of the sash
22, effectively sealing this aperture which ordi
narily exists between the sides of the usual sash
60 and stile construction. Also because of the con
stant resilient force exerted by the resilient strip
against the side 22 of the sash, the sash will be
prevented from rattling or vibration as the re
silient force will counteract any movement of
65 the sash caused by the wind or vibration.
Thus, this resilient strip 24 which is prefer
ably concave but may take any other desirable
shape not only serves as an effective stop for
the sash but also serves both as weather strip
70 ping and as an anti-rattler.
Referring now to Figure Zl, one of the many
possible modi?cations of the strip 24 is shown
attached to stile | | and exerting pressure against
the side 22 of the sash 2| which is compressing
75 it. This type preferably consists of two parts 30
and 3| concave in cross section connected by a
convex portion 32 all of these surfaces preferably
being pressed from one resilient metal strip.
This forms two surfaces pressing against the
side 22 of the sash 2| and leaves a portion 32 5
which may be securely attached to the stile by
nails 28 or by any other suitable means.
A second modi?cation is shown in cross sec
tion in Figure 5 a channel 33 having been cut into
the edge 22 of the sash 2| and a concave metal 10
strip 24 having an upturned lip 2'! is secured
in this channel so that the concave surface of
the strip 24 faces the sash and the convex sur
face abuts against and is compressed 'by the
stile II when the sash is in position against the 15
stile. To prevent the upper and lower edges 39
of the concave strip 24 from digging’ into or
forming undue friction with the stile II as the
sash 2| slides in its track, I preferably secure
the ends of the strip to the ends or sides of the 20
stile. In Figure 6, I have shown the edges 39
of the strip 24 secured to the side of thevsash
at 41! and secured to the end of the sash at 4|.
The edges are secured by any suitable means
such as by nails 42.
25
Referring now to Figure '7, I have shown a
series of cut-out portions 34 in the side 26 of the
strip which is to be secured to the surface on
which the strip is to rest. These cut-out por
tions, which are preferably in the shape of tri 30
angles, are cut through strip 24 only on two edges
35 and 36 and then bent downwardly using the
third edge 31 as an axis to form a series of
pointed lugs 38 (Figure 8) preferably perpen
dicular tothe plane drawn between the edges 26 35
and 27 of the concave strip 24. These lugs will
form an e?icient means for attaching the strip
24 to any surface. Thus, I have provided two ,
modi?cations for placing and shaping the strip
each of which will perform the unique function 40
of acting as a stop for a sash in a window frame,
an effective weather strip, and an anti-rattler.
And I have also provided an e?icient and in-,
expensive means for attaching the strip to a
surface.
45
It will now become clear that with my unique
and simple device and method, I am able to per
form three de?nite functions in holding a sliding
member at any desired position within its track,
sealing the aperture between the sliding mem 50
her and its track, and preventing excessive
lateral movement of the member as would cause
rattling of the member within its tracks. It is
to be understood that each of these functions is
of independent value and the construction may 55
'be arranged to accomplish anyone or more of
them as an embodiment of features of the in
vention. Furthermore, it will be noted that this
has been accomplished in a simple and efficient
manner by a device which may be manufactured 60
at extremely low cost. All of the factors accom
plished by this device offer material advantages
in the production of this device and to the user.
It will thus beseen that I have provided a
thoroughly practical device for holding a sliding
member within its frame at any desired position
in which the several objects hereinabove men
tioned as well as many others are successfully
accomplished.
As many possible embodiments may be made
of the above invention and as many changes
might be made in the embodiment above set
forth, it is to be understood that all matter here
inbefore set forth, or shown in the accompany 75
