PROVISIONAL SPECIFICATION.
An Improved Means for Fastening and Unfastening Window Beads.
I, ALONZO READ of Markett Street, Kenosha, County of Kenosha, Wisconsin,
United States of America, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means for fastening so as to be readily removable the
bead or guide strips which come against the vertical front edges of the window sash
and prevent it from falling out into the room. In the window frame at the part
where the bead is to be fixed a number of circular recesses are made at suitable
distances apart. Sockets with orifices like a key hole are fixed in these recesses.
Corresponding holes are made along the bead into which small headed screw bolts
are passed. A screw bolt is then passed by its head into the larger portion of the
orifice of each socket and by its stem along the narrower portion of the orifice.
The under face of the socket is provided with a serrated surface for holding the bolt
firm when tightened up by a nut on the other side of the bead. In this way the
bead may be adjusted with precision against the window sash so as also to form a
weather strip.

COMPLETE SPECIFICATION.
An Improved Means for Fastening and Unfastening Window Beads.
I, ALONZO READ of Markett Street, Kenosha, County of Kenosha, Wisconsin,
United States of America, Manufacturer, 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 means for fastening the window bead known as the
guide strip, so as to be readily removable when it is desired to take out the sash of
a window and for making the said guide strip serve as a weather strip capable of
being adjusted into close contact with the sash.
In the drawing
Fig. 1 is a sectional view of a window, shewing the frame provided with the
improvements of this invention.
Fig. 2 is an enlarged detail sectional view through line 2-2 of Fig. 1.
Fig. 3 is a face view of one of the sockets by which the guide strip is held,
shewing it embedded in the window frame, the bead being omitted.
Fig. 4 a detail sectional view through line 4-4 of Fig. 3.
Fig. 5 a back view of one of such sockets, the window frame being omitted.
Fig. 6 is a detail view partly in section of one of the set bolts or screws which
co-operate with the sockets in securing the guide strip in place.
A is the window frame at suitable distances in the height of which are formed
circular cavities B at a distance from the edge of the frame and of less diameter
than the width of the guide strip or bead C so as to be completely covered by such
strip and thus entirely excluded from view when the strip is in place. Arranged
in each of the cavities B is a circular socket D provided with a face plate E flush

with the surface of frame A and provided with a key hole shaped slot F for the
passage of the set bolt or screw (r. The socket D is so arranged in its cavity that
the shot F therein will be in a substantially horizontal position with its enlarged
end away from the sash II and may be fixed by screws I screwing into the
The set bolt G is passed with its head through the large part of the slot and
then lid so as to engage underneath the face plate E the narrow portion of the slot
preventing its withdrawal from the socket D. The lower end of the bolt has a
square part y fitting the narrow part of the slot and also a complementary socket or
perforation in the strip C. The purpose of this, is to hold the bolt against rotary
movement when the guide strip C is pulled outward so as to bring the bolt into the
enlarged portion of the slot and further to hold the squared part g' so that it may be
readily slid into the contracted part of the slot when the guide strip is forced towards
the window sash. J are ornamental thumb nuts and j washers (one only shewn) for
screwing down the strip C. In this way the latter may be adjusted to and from
the sash as desired and may be set against the sash so as to produce an air tight
joint and thus serve the twofold purpose of a guide strip and weather strip. When
it is desired to remove the sash for any cause, the thumb nuts J are loosened and
the strip drawn away from the sash until the bolts G enter the enlarged portions f
of the slots F, whereupon the strip may be entirely removed in drawing the heads
of the bolts through the said enlargements, which are extended to the inner
periphery of the socket so that there may be no overhanging edge to engage the
head of the bolt, and to the same end the under edge of the of the enlarged portion
of the slot is bevelled off as shewn at f' (Fig. 4).
In order that the guide strip C may be held up against the sash H when once
adjusted to the proper position and the thumb nuts set, the under side of the
plate E is furnished along the edges of the contracted portion of the slot F with a
number of teeth or serrations e against which the head of the bolt impinges and by
which it is firmly held in place. The bolts may also be formed with a small
pinched up portion or tooth 92 at each corner of the square part for better
engagement of the bolts with the teeth or serrations e. The teeth are prevented
from catching against the corners of the slot in the face plate by rounding such
corners off as at f2 and bevelling their under sides.
In order that the lower half only of the guide strip C may be removed
irrespective of the upper half, when it is desired simply to remove the lower sash,
or in order that the lower half only of the guide strip may be adjusted, the guide
strip is divided at a point slightly above the top of the lower sash as shown at N
(Fig. 1).
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:-
In a window bead fastener, the combination of the window frame having sockets
fitting therein, and each consisting of a rim and the face plate E provided with a
slot having a straight portion with serrations e on both its under edges and an
enlarged portion f extending to the edge of said rim and having rounded corners få
where it joins the straight portion of said slot, the under edge of said enlarged
portion being bevelled from the straight portion to the edge of said rim, the bead
with the set bolt passing through the same and into the slot and having a head
provided with teeth adapted to engage with said serrations, substantially as
described and shewn.
