I, JAMES LUMSDEN, Brassfounder, 138 John Street, Aberdeen, do hereby
declare the nature of this invention to be as follows:-
A metal plate for fixing to a window sash, or other object, with spikes or screws,
and having two raised sides, between which the cord, rope, or chain is placed; in
each of these sides is a tapered groove into which is put a metal wedge provided
with two teeth, which press the cord, rope, or chain into a V shaped or square

An Easy and Effective Method of Fastening Cords, Ropes, or Chains
to Window Sashes or other Objects.
I, JAMES LUMSDEN Brassfounder 138 John Street Aberdeen 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 :-
The object of this invention is to provide an improved device for securing or
fastening the cords, or chains of a window sash thereto, a further object being to
provide an improved device or devices, which are adapted to be secured to window
sashes for the purpose of suspending the same by means of cords or chains which
are attached to counter-balance weights which move in vertical spaces or chambers
formed in the frame a further object being to provide devices of this class which.
may be used for suspending various other articles in addition to window sashes.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which
Fig. 1, is a plan view of the innerside of my improved fastening device ;
Fig. 2, a longitudinal side section thereof, at C. C. in Fig. 1.
Fig. 3, a cross section thereof at H, H. in Fig. 2.
Fig. 4, a cross section thereof at E, E in Fig. 2.
Fig. 5, a back view of a wedge, or clamp which I employ:
Fig. 6, a bottom view thereof: and
Fig. 7, a side view.
In the practice of my invention, I provide a metal base plate, A, which
adapted to be secured to and countersunk in the side of the frame of a window
sash or other article, and which is provided with ends, a, through which bolts or

page_text: screws are passed for securing it in position, and with side plates, a 2, which are
arranged centrally thereof, and between the ends of which side plates are
triangular notches or recesses, a 5, and the rope, cord or chain, B, by which the
sash or other article, is supported is passed between these side plates, and said
side plates are provided with longitudinal inwardly directed flanges, a 3, and I also
provide a wedge or clamp, D, which consists of two side plates, d, connected at
one end by a transverse shoulder, d 2, which is secured to the top of the side
plates, and the opposite ends thereof, being united by a curved plate, d 3, which
is downwardly curved as shown in Figs. 5, and 7; and the underside of the
shoulder d 2, is provided with a longitudinal projection, d 5, and the underside of
the cross plate, d 3, with a similar longitudinal projection, d6, and the underside
of the side plates, d, are inwardly curved as shown at d 7, in Fig. 7.
The metal base plate A, is preferably cut out centrally thereof as shown at a 4,
in Fig. 2, and in practice the rope, cord, or chain, B, is passed between the side
plates, a 2 and the clamp or wedge D, is passed over said rope, cord or chain, and
between the side plates in the direction of the arrow, c, of Fig. 2, and in this
position the shoulder d2, passes between the longitudinal inwardly directed
flanges, a 3, and as the rope cord or chain is drawn through the fastening device
it is forced downwardly by the wedge or clamp into said triangular notches or
recesses, and securely locked in position, it being understood that the pull on the
rope, cord or chain is in the direction of the arrow z of Fig. 2, and the inwardly
directed projections or teeth d 5, and d6, on the wedge or clamp aid in holding
the rope, cord or chain in place.
This device is simple in construction and operation, while being comparatively
inexpensive, and is perfectly adapted to accomplish the result for which it is
intended, and my invention is not limited to the exact size and shape of the various
parts herein shown, and described, and I reserve the right to make all such
alterations therein, and modifications thereof as fairly come within the scope of the
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim as new and desire to secure by Letters Patent :-
1. The herein described fastening device for connecting cords or chains with
window sashes and other articles, which consists of a base plate provided with
outwardly directed side plates, which are provided with inwardly directed flanges
and between which the rope, cord or chain is intended to be passed, and a clamp
or wedge which is adapted to be passed between said flanges, and to securely
hold the rope, cord or chain in connection with said base plate, substantially as
shown and described.
2. The herein described fastening device for connecting cords or chains with
window sashes, and other articles, which consists of a base plate provided with
side plates having inwardly directed flanges, and between which the rope, chain or
cord is intended to be passed, and a clamp or wedge which is adapted to be passed
between said flanges and to securely hold the rope, cord or chain in connection
with said base plate said base plate being provided with notches or recesses at the
ends of said side plates, and said clamp or wedge being provided at one end
with a shoulder or projection which extends outwardly between the side plates
and being inwardly curved at the opposite side, substantially as shown and
described.
3. The herein described fastening device for connecting cords or chains with
window sashes, and other articles, which consists of a base plate provided with
side plates having inwardly directed flanges, and between which the cord or chain
is intended to be passed, and a clamp or wedge which is adapted to be passed
between said flanges and to securely hold the rope, chain or cord in connection
with said base plate, said base plate being provided with notches or recesses at the
ends of said side plates, and said clamp or wedge being provided at one end with

page_text: a shoulder or projection which extends outwardly, between the side
being inwardly curved at the opposite end and being provided also at each
end with inwardly directed teeth or projections, substantially as shown and.
described.
