2 Claims.
The present invention relates to what is be
lieved to be a novel'method and means of pro
viding a dependable weather seal between abut
ting portions of frame members such as are used
5 in the'construction of wooden door and window
frames, and the primary purpose of the inven
tion is to incorporate a plate-like shield in the
structure at a point of vantage to provide a sub
stantially water-tight jointlbetween the adjoining
(CI. 29-11)
into the groove or kerf 9, has an outwardly bent
feather edge knife formation, as indicated at I3.
The lower horizontal ?ange‘id has a similar up
turned knife edge i5, and these features are
de?ected laterally at the requisite angle to in
sure ?rm imbedding into the parts 6 and 1, as
disclosed to advantage in Figure 1.
the so-called seal i i is of a length commensurate
with the transverse dimensions or widths of the
parts 6 and 1. Consequently, when it is in place,
it bridges the existing or conventional vertical
conception of actual practice, I found it expedient
channel it, as disclosed in Figure 2. Normally,
and practicable to utilize a right angularly shaped without the seal in place, water runs down the
plate, this being employed as an insert and being groove 15 and between the ends of the parts
15 ?tted into saw kerfs or grooves formed in the
6 and l, materially shortening the lives of such
abutting companion portions of the stile and . parts. Not only this, the water, when abnormal
stool, respectively, whereby to provide a simple, or excessive, is apt to be ruinous to the wall struc
portions of the frame structure.
In reducing the principles of the inventive
economical, and efficient assemblage aptly ?tted
for the purposes intended.
Other features and advantages will become
more readily apparent from the following de
scription and drawing.
In the drawing:
Figure 1 is a fragmentary sectional viewshow~
5 ing adjoined end portions of the stile and stool
of the window frame with the improved sealing
plate in position.
Figure 2 is a view of Figure 1 observing it in
a direction from right to left.
Figure 3 is a fragmentary perspective view
showing the stile and stool in the process of as—
sembly with the saw kerfs or grooves formed
Figure 4 is an elevational detail View of' the
safeguarding plate unit per se.
In the drawing the conventional wooden win
dow frame is denoted by the numeral 5. I‘ have
shown one'vertical stile 6 and the adjoining com
plemental horizontal stool ‘I.
As iscustomary,
40 one end of the stool ‘I is ?tted into a keyway
8 formed in the stile, as illustrated in Figure 3.
Before the parts are assembled, relatively nar
row saw kerfs 9and ID are formed at the points
shown to provide slideways'for the shield or
weatherproo?ng unit I i. This part H is slipped
into place after the complete window frame has
been assembled.
Naturally, the part ll may vary in propor
tion, and its constructional details may be
slightly different from the arrangement depicted
in Figure 4. Essentially, however, the part H
comprises a substantially L-shaped plate resem
bling, in some respect, a light weight miniature
angle iron. In the preferred embodiment of the
invention the upstanding ?ange l2, which ?ts
ture, wall paper, and so on.
It is to be observed that the cross-sectional
shape of the part i ! is such that the vertical ?ange
thereof abuts a portion of the so-called key
way 8, the free knife-like edge thereof projecting
into the kerf 9 and being securely imbedded in
the body of the part 6. The horizontal ?ange
extending into the kerf l0 and being similarly
imbedded enables said part H to effect a more
secure joint between the parts 6 and. 1 than would
otherwise be. Primarily, however, the interlock
ing feature is secondary to the weatherproo?ng
feature, as is evident.
It is thought that the description taken in con
nection with the drawing will enable a clear un
derstanding of the invention to be had. ‘There
fore, a more lengthy description is thought unnec
to. In
While the preferred embodiment of the inven
tion has been shown and described, it is to be un
derstood that minor changes coming within the
field of invention claimed may be resorted to if
I claim:
1. In a structure of the class described, a ver
tical stile having a horizontal groove intersected
by a vertical groove, a stool having one end ?t
ting into said horizontal groove, said stile and 4
stool being provided with right angularly disposed
saw kerfs extending completely across the trans
verse dimensions thereof, and an L-shaped metal
plate interposed between the stile and stool and
having its flange portions ?tted into said kerfs
in the manner and for the purposes described.
2. In a structural assemblage of the class de
scribed, a vertical stile having formed in one
face thereof a horizontal groove, said groove
extending transversely from one vertical edge
kerf and opening through opposite longitudinal
to the opposite vertical edge, the upper wall of
said groove being provided with a vertically dis
posed kerf running horizontally the complete
length of the groove and opening through the
opposite vertical edges of said stile, a horizontally
disposed stool having one end ?tting snugly into
edges of the stool, and an L-shaped metal plate
interposed between the stile and stool and hav
ing one ?ange projecting into the first-named
kerf, and the other ?ange projecting into the
second-named kerf, said ?anges having a driv
said groove, that end of the stool projecting into
said groove being formed with a kerf comple
mentary to said ?rst-named kerf and extending
mensurate with said kerfs.
horizontally at right angles to said ?rst-named
ing ?t in said kerfs and being of a length com
