Improvements in Sash Line Fasteners.
I, LEVI WILLIAMS CROUCH, of Crouch Avenue, Laurel Hill, in the City of
Norwich, County of New London, State of Connecticut, 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 has for its object the production of a simple and inexpensive
device that may be readily attached to a sash cord, chain, or tape and whose pro-
jecting end portion is shaped to engage the sash without the aid of screws or other
supplemental parts.
To explain the said invention I have provided the annexed drawings in which
Figures 1 and 2 are respectively side and edge views of a portion of a window
sash having the sash cord secured thereto by the said newly invented device.
Figure 3 shows face and edge views of said device detached and Figure 4 is a
cross-sectional view on line x-x of Figure 2. Figures 5 and 6 illustrate slight
modifications of said invention. Figures 7 and 8 illustrate said device as used
with a chain and steel tape instead of with cord.
In these drawings the letter a indicates a window-sash having its edge bored as
at a¹ and channeled as at a³ to provide recesses in which the cord b and its fasten-
ing device may be seated. Said device consists of two essential elements, one
being a body portion c adapted to be clamped upon the cord, and the other a head
portion c¹ so formed that it may engage the circumferential walls of the recess a¹
and thus prevent end-wise movement of the cord independently of the sash.
I prefer to make said device of sheet metal of the general form shown in
Figures 1, 2 and 3, the body portion being adapted to be bent to fold around a
cord, as seen in Figures 2 and 4, and I also preferably provide in the said body,
portion one or more spurs c³ that may enter the cord, as seen in Figure 4, and thus
help to prevent the withdrawal of said cord from the embrace of said body
portion. I have shown the edges of the body portion as provided with teeth c³
that are off-set from each other (see Figure 2) so that when the body is folded
upon the cord they may inter-lock with each other and thus embrace a much
smaller cord than if the edges were plain.
The head portion of said device is substantially flat, its outline being circular
and of about the same diameter as that of the recess a¹ in the sàsh. Spurs c
are provided in that part of the head adjacent to the body portion and when the
head is laid in the said recess and drawn forcibly upward these spurs enter the
wood of the sash as seen in Figure 2, and then serve to secure the cords to
the sash with no possibility of their becoming disengaged by accident. They may
however, be separated by overcoming the weight of the counter-balance and "with-
drawing the spurs from their seats in the wood of the sash.
When it is desired to use the described device it is only necessary to lay the
end of the cord in the partly folded body portion c and close said body portion
tightly around the cord, when the head portion of the device may be entered in
the recess a¹ and its spurs crowded slightly into the wood.
In the fastening device thus far referred to the head portion c is off-set from
the body portion c as at 5 thus causing the spurs to lie in a plane somewhat in

page_text: the rear of that occupied by the body portion. While this is desirable, it is not
absolutely necessary, as the body and head portions may be in the same plane,
as shown in Figure 5, but by off-setting the head, as just described, the spurs are
brought into engagement with the more solid wood in the rear of the channel a²,
in which the cord lies, lessening somewhat the liability of splitting the sash. It
should be noticed that if the spurs are drawn completely into the wood the
off-set portions will then serve as a stop to limit the further entrance of the
spurs.
.
In Figure 6 I have shown a sash cord fastener embodying the described inven-
tion but made completely of wire, the body portion being bent to form loops d-d¹
that may be bent around the cord, said loops being connected by intervening
portions and the projecting portions of wire being brought together and twisted
as at and finally bent outward to form spurs d' that may enter the wood of the
sash in the same manner as the described spurs c in the sheet metal form of
fastener. While this wire fastener is quite practicable, in most instances, I
prefer the sheet metal form as it is very easily and cheaply produced without the
aid of expensive special automatic. machinery.
i
The described sash cord fastening device does away with the necessity of tying
the knot in the end of the cord as very commonly practiced and embodies in a
single simple piece all the desirable features of more expensive and complex
devices sometimes used for the same purpose.
.י
In some instances chains or metallic tapes are used instead of cords and in
Figures 7 and 8 I have illustrated the said "fastener" as so used. In Figure 7
a tongue is formed in the body portion of the fastener which tongue passes
through one of the chain links and is bent downward as seen in said Figure 7.
The spurs on said body portion are then forced down upon the chain thus
clamping the fastener securely to said chain..

When a tape is used the sides of the lower portion of the body of the fastener
are first bent inward to form a loop 7 through and around which the end
portion of the tape is wound one or more times. The upper portions of the
sides are then bent inward and folded snugly down upon said tape thus clamping
it securely to the fastener.
Having now particularly described and ascertained the nature of my s'aid
invention and in what manner the same is to be performed, I declare that what
I claim is:
ĭ
1. A sash line fastener comprising a body provided with means for securing
it to the end of the cord, chain or tape: prongs or spurs substantially parallel
with said body at one end thereof, whereby the pull upon the line will force said
spurs into the sash substantially as set forth.
2. A sash line fastener, comprising a body provided with means for securing
it to the end of a cord, and provided at one end with prongs or spurs substantially
parallel with said body and off-set from the line of the pull of the cord upon the
same, substantially as set forth.
1.
3. A sash line fastener comprising a body, one end of which is provided with
teeth for securing it to the end of a cord, and the opposite end is provided with
a crescent shaped head, the ends of the head forming prongs or spurs substantially
parallel with the body and adapted to be forced into the sash by the pull upon the
cord, substantially as set forth.
