page_text: I, ROBERT EDWARD HENRY of 35 Stanhope Gardens, S.W., in the county of
Middlesex, Lieutenant Colonel in Her Majesty's Army, do hereby declare the nature
of this Invention to be as follows:―
My invention consists mainly on improvements in the window sash-line fastener for
which Letters Patent were granted to me bearing date 14th January 1885 and
numbered 535.
י
In my present invention, I adhere to the same general principles of construction
and method of use as described in the specification of my aforesaid Letters Patent,
but I form the fasteners according to the following improved and modified methods.
I insert a screw in the groove of the sash, leaving the head projecting slightly, so
that when the fastener is slipped into position, the said screw will enter a short open-
ended slot in the lower end of the fastener and prevent it being strained or bent out
of place.
In cases where a sash is made with a "joggle" instead of a square corner, I form
the fastener with the short arm at right angles to the usual position, and just
square of the top off the "joggle," for the said short arm to rest upon and be secured
thereto by screws in the usual way.
It is found in practice that the said screws have ample holding power for the
heaviest sashes, but to meet any possible objection to such means of attachment, I
may
affix a small iron angle-piece, by two or more screws to the vertical part of the
sash, the top short arm of the said angle piece being drilled and tapped for one or
more screws, with metal threads, to secure the fastener.
By forming two or more key-hole slots in the fastener, and placing corresponding
screws in the vertical part of the sash, I may dispense altogether with the top angle-
piece, and screw and open slot at bottom.
Again the fastener may be of semicircular or curved section and be held by two
screws at the bottom, which first enter a slot in the lower end and then, on partly
rotating the fastener, pass into short transverse slots.

page_text: In this case only a short angle piece at the top with one small screw, to prevent the
fasteners twisting back, will be required.
For round headed sashes, I may form the upper part of the fastener to a corre-
sponding curve, and in order to give ready access to the fastening screws, I provide
one or more steps in the curved part through which the said screws pass.
In place of the said curved portion, or of the top angle-piece for square headed
sashes, I may provide one or more small lugs on the back of the fastener with holes
through them to receive pins or screws passing horizontally through the sash, and to
the top of the fastener a short length of wire or metal strip may be attached for the
purpose of drawing out the said fastener from the groove and replacing it.
Instead of passing the screws, which hold the end of the cord in the fastener,
through both sides of the fastener, I now prefer to employ three or more screws
passing through bosses formed inside alternately on opposite sides of the fastener, so
that the cord is bent in and out as well as pierced by the screws and thus held with
perfect security.

page_text: Improvements in Sash-line Fasteners.
1; ROBERT EDWARD HENRY of 35 Stanhope Gardens in the county of Middlesex,
Lieutenant Colonel in Her Majesty's Army, 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:
My invention consists mainly in improvements on the window sash-line fastener for
which Letters Patent were granted to me bearing date 14th January 1885 and
numbered 535.
In my present invention I adhere to the same general principles of construction
and method of use as described in the specification of my aforesaid Letters Patent
but, I form the fasteners according to the following improved and modified methods
as shewn in the accompanying two sheets of drawings, in which fig. 1 is a front
elevation and fig. 2 a side elevation of one form of my improved fastener. Fig. 3
is a side elevation and fig. 4 is a front elevation of part of a window sash with the
fastener in position. Fig. 5 is a side elevation of the upper part of a fastener of a
somewhat modified construction. Figs. 6 and 7 are elevations of the upper part and
Fig. 8 is a plan of a fastener shewing a further modification, and Figs. 9. 10 and 11
are elevations and Fig. 12 is a plan of a modification, shewing a tubular form of
fastener. Similar letters of reference are used to denote similar or corresponding
parts throughout the said drawings.
In Figs. 1. 2. 3 and 4. A is the vertical part of the fastener and B the horizontal
part affixed to the sash C by the screws D, D. A screw E is inserted in the groove
of the sash with the head projecting slightly, so that when the fastener is slipped into
position, the said screw E will enter a short open-ended slot F in the lower end of the
fastener and effectually prevent the said fastener being strained or bent out of
place.
"
In cases where a sash is made with a "joggle" instead of a square corner, I form
the upper part of the fastener, as shewn in Figs. 6. 7 and 8, with the short horizontal
arm B at right angles to the usual position as shewn in Figs. 1 2, 3, and 4, and in
fixing this form of fastener in place I just square off the top of the said joggle
for the short arm B to rest upon and be secured thereto by screws D, D, as before.
It is found in practice that the said screws have ample holding power for the
heaviest sashes, but to meet any possible objection to such means of attachment, I
may affix a small iron angle piece H, Fig. 5, by two or more screws J, J, J, to the
vertical part of the sash C. The top short arm H' of this angle piece is drilled and tapped
for one or more screws K with metal threads to secure the arm B of the fastener.
Instead of passing the screws which hold the end of the sash line L in the fastener
through both sides of the said fastener I now prefer to employ three or more
screws M, M, M, passing through bosses formed inside alternately on opposite sides of
the fastener, as shewn clearly in Figs. 1 and 4, so that the sash line is bent in and out,
as well as pierced by the screws and thus held with perfect security. The screws are

page_text: pointed to enable them the more readily to pierce the line, and when home, as shewn
in Fig. 4, their points just enter holes or indentations in the side of the fastener.
In figs. 9. 10 11 and 12 a fastener is shewn having the lower portion of the vertical
part A in the form of a tube and the upper part thereof semi circular.
A vertical slot N is formed at the bottom of the tube, with two transverse slots N',N',
leading out of the said vertical slot. Two screws are affixed in the sash groove,
similarly to the screw E (Figs. 3 and 4.) so that when the fastener is slipped down
into place these screws enter the vertical slot N and on partly rotating the fastener
they enter the transverse slots N1, N2. The said screws in this case bear all the strain,
and the said strain being applied transversely there is no tendency to draw the screws
endways out of the wood. To prevent the fastener turning back out of position a small
screw is placed through the small lip or projection Q, into the top of the sash, but no
part of the strain is borne by this screw. M, M, M are the screws holding the end of
the sash line Lin the tubular part of the fastener in the same manner as that described
and shewn in Figs. 1. 2. 3. and 4.
In applying my improved sash line fasteners to round headed windows, or windows
other than square, I may modify the form of my said fastener to meet the shape of
such sashes, the essential principles of construction however remaining the same in
all cases.
As a further alternative arrangement I may provide one or more small lugs in the
back of the fastener with holes through them to receive pins or screws passing
horizontally through the sash, but as this entails cutting a deeper groove in the sash,
I prefer in practice the previously described methods of construction.
In some cases where fasteners are difficult of access I find it convenient to attach a
short length of wire or sheet metal to the top of the fastener to assist in drawing it
out from the groove and replacing it.
The general advantages and method of use of these improved fasteners is
substantially the same as that set forth in my aforesaid Letters Patent No. 535
of 1885.
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 sash-line fastener constructed substantially as herein described and shown
with referenee to Figs. 1. 2. 3 and 4. of the accompanying drawings.
(2). In a sash-line fastener the construction of the arm B to suit sashes with
"joggles," substantially as herein shewn and described with reference to Figs. 6. 7. and
8 of the accompanying drawings.
(3). The combination with a sash-line fastener of an angle piece H, substantially as
and for the purposes herein described and shown with reference to Fig. 5 of the
accompanying drawings.
(4). A sash line fastener constructed substantially as herein described and shewn
with reference to Figs. 9. 10. 11 and 12 of the accompanying drawings.
(5). The construction of a sash line fastener with lugs or projections on the back,
and secured in the sash by pins or screws passing horizontally through the said sash
and lugs, substantially as herein described.
