COMPLETE SPECIFICATION.
Improvements in Window Frame Pockets and Method of Making
the same.
I, FRANCIS VOSBURGH PHILLIPS, of No. 981 West Twenty-fifth Street,
Chicago, Cook County, Illinois, United States of America, Salesman, 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 the form of, and the mode of forming, window stile
'pockets" and consists in the matters hereinafter set forth and claimed.
In the accompanying drawings:
Figures 1 to 5 inclusive illustrate a pocket piece severed, according to my.inven-
tion, from the edge to the parting stop groove of a stile.
Figures 6, 7 and 8 illustrate a stile having the pocket extending laterally from
the parting stop groove only part way to the edge or margin of the stile.
Figures 9, 10 and 11 illustrate the old style of pocket and the method heretofore
practised in forming such a pocket, the disadvantages of such old style being
made apparent by these illustrations.
Figure 1 is a perspective view of a portion of a window frame containing a stile
having a pocket formed in accordance with my invention.
Figure is an enlarged view of a portion of the stile having my improved
pocket cut therein, the pocket piece being removed.
Figure 3 is a vertical section on the line 3-3 of Figure 2.
Figure 4 is a horizontal section on the line 4-4 of Figure 2 looking downward.
Figure 5 is a perspective of the pocket piece detached.
Figure 6 is a front elevation.
Figure 7 is a perspective, parts of the stile being broken away to illustrate the
joint formed in accordance with my invention.
Figure 8 is a modification within my invention.
Figure 9 is a perspective view of a stile showing the pocket piece removed.
Figure 10 is an edge view showing the pocket piece replaced ready to be planed
off flush with the stile; and
Figure 11 is a perspective view of the old style of pocket piece detached and
notched preparatory to its replacement in the stile.
A represents a window stile of which B is the pocket piece cut from the stile
hear the lower end of the latter for the purpose of giving access to the sash
weight box which is provided in the window frame exterior to the stile, as shown
n Figure 1.
Referring first to Figures 9, 10 and 11 which illustrate the form of; and mode of
forming, the pocket as heretofore made, it will be noticed that the pocket piece B
s severed at its ends from the stile A by two saw cuts or kerfs at a b. which are
nclined in the same direction or downwardly toward the sash face of the stile.
The pocket piece B so formed at its ends is also cut from the stile by a longitudinal
kerf or cut at c. After the pocket piece has been removed it is notched at a¹ a
Figure 10) at its upper inner edge, its lower end is secured to the lower end of
he opening in the stile from which it was taken by means of a screw passed
hrough the overlapping lower end of the pocket piece into the underlapping
portion of the stile, as shown, and nails a³ are driven into the upper inclined face
of the opening in the stile in position to hold the pocket piece firmly outward
gainst the inclined wall of the stile opening and after the pocket piece has been
hus secured in the stile its projecting face is planed down flush with the sash face
f the stile.
:

page_text: Formed in accordance with my improvement the pocket piece does not protrude
beyond the face of the stile and no subsequent planing thereof is required.
In my improved construction one or both ends of the pocket piece is severed
from the stile by two transverse cuts or kerfs extending inward from the opposite
faces of the stile only part way through the latter and a fracture of the wood is
made lengthwise of the grain, extending from one of said cuts to the other. These
two cuts have the offset relation illustrated in Figures 1, 2 and 3 in which the
cut C at the lower end of the pocket, made from the front of the stile, is a short
distance below the cut C₁ made from the rear face of the stile. The cuts or
kerfs C and C¹ may be horizontal, but if at the lower end of the pocket, are
preferably inclined downwardly towards the sash face of the stile, as shown.
Two oppositely arranged cuts are shown as severing the upper end of the pocket
piece from the stile. The direction of the cuts C and C' at one end (usually the
upper end of the pocket) may be varied, but they may better be so arranged and
directed as to give interlocking relation between the end of the pocket piece and
the end of the opening in the stile, so that the said end of the pocket piece may be
retained easily against inward movement and desirably against both inward and
outward movement, without fastening, and so also that the front sash face of the
pocket piece shall be flush with the sash face of the stile when said pocket piece is
returned to its place in the latter. In the construction shown in Figures 1 to 7,
which is preferred, both partial cuts or kerfs C' and C' incline downwardly
towards the sash face of the stile and are offset or located in different planes, like
the cuts C and C₁ at the opposite end of the pocket. The cut C* may, however,
be directed upwardly instead of downwardly so as to meet the inuer end of the
upwardly and inwardly directed cut C*, as shown by full lines in Figure 8, or,
being made at a point somewhat lower down than the cut C2, it may reach inward
to the plane in which the cut C* terminates.
The kerfs which do not intersect are located at such a distance from each other
that a hammer blow struck upon the pocket piece after such kerfs have been made,
will result in breaking or splitting the wood from one of these kerfs to the other.
Such splitting of the wood of course gives a separation in a plane substantially
parallel with the faces of the stile and pocket piece without the removal of material,
so that when the pocket piece is reinserted its faces are in their original planes and
flush with the faces of the stile.
In practice the non-intersecting kerfs will preferably be made about half an inch
apart in order to give a split of that length.
The through vertical cut or cuts detaching the side or sides of the pocket piece
from the body of the stile may be made either before or after the partial transverse
kerfs, but should be made before the vertical fracture is made.
It is plain that when, in the construction above described, the pocket piece is
replaced in the stile and secured by a screw at its overlapping end or ends, the face
of the pocket piece will be flush with the face of the stile and that no planing or
dressing of the pocket piece is required. By this means the cost of constructing
the stile with the pocket is materially reduced while the pocket is better for the
reason that the pocket piece will always have its front face flush with the sash face
of the stile whenever and by whomsoever it may be replaced.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1-A pocketed window stile and pocket piece formed of the same board, the
stile opening and pocket piece joining at one or both ends in an indirect division
line comprising two offset, transverse cuts extending inwardly from the opposite
faces of the stile to a plane between said faces, and a vertical fracture extending
from one of said cuts to the other.
2:-A pocketed window stile and pocket piece formed of the same board, the
stile opening and the pocket piece having interlapping surfaces at their upper ends

page_text: and having at their lower ends an indirect line of division which comprises two
offset, transverse cuts extending inwardly from opposite faces of the stile to an
intermediate vertical fracture which connects them.
3: The method of forming a pocket in a window stile which consists in cutting
the stile inwardly part way through from opposite faces and in different planes, and
then splitting the wood from one of such cuts to the other.
Dated, at Chicago, Cook County, Illinois, U.S.A., this 14th day of September
1892.
