Improvements in Window Fasteners.
I, LAURA HOFHEIMER, of 166 Pacific Street, in the City of Brooklyn, County
of Kings, and State of New York, United States of America, Telegraph Operator
do hereby declare the nature of this invention and in what manner the same is to be
performed and to be particularly described and ascertained in and by the following
statement:-
1
The object of my invention is to construct a sash lock that will prevent a robber
from opening the window by inserting a tool between the sashes to throw the lock.
The invention: consists of two plates hinged together one of which can be secured
to tho rail of a window sash in combination with a pin or bar to be carried by the
other sash to rest over the plate that lies upon the rail of said sash.
Reference is to be had to the accompanying drawing forming a part hereof,
wherein,
Fig. 1, is a plain view of the sash lock applied to a window shown in the locked
position;
Fig. 2, is a similar view in the unlocked position;
Fig. 3, is a cross, section on the line - in Fig. 1.
In the accompanying drawings, in which similar letters of reference indicate
corresponding parts in the several views, the letter A, indicates the top rail of a
lower sash and B, is the bottom rail of an upper sash, which rails meet in the
ordinary manner when closed. The lock consists of two plates D, E, hinged
centrally together at F. The plate D, is secured to the rail A, as by screws d, and
is preferably Het back of the inner edge a, of the rail so that the latter will afford a
support for the plate E. The plate E, is adapted to be swung over and upon the
rail B, as in Fig. 1, and 3. G, is a pin or bar detachably carried on the rail B,
in eyes or staples g, secured thereto in such position, at the ends of plato E, that the
pin or bar G, can be passed through said eyes or staples and hold the plate E, down
as in Figs. 1 and 2.
When the window is to be locked the plate E, is swung over rail B, and pin or
rod G, is passed through eyes g, and over plate E, so that if it is attempted to raise
rail A, the pin G, will prevent the plate E, from leaving rail B. To open the
window it is only necessary to remove pin G, and fold plate E, back. The edge a, of
rail A, prevents the plate E, from swinging down when rail A, is lifted. A robber
cannot open the lock by forcing a tool or knife between rails A, or B, because pin G,
prevents the plate E, from being raised.
The device is simple in construction, effective in use, not liable to get out of order
and can be used by anyone..
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 lock consisting of two plates hinged together, one of which plates is
adapted to be secured to a sush rail, and means to hold the other plate down upon
the rail of another sash, substantially as shown and described.
2. A sash lock consisting of two plates hinged together, a pin or bar to lie over
one of said plates, and eyes or staples to receive said pin to bold it in position,
substantially as shown and described.

page_text: 3. The combination with the meeting rails A, B, of window sashes, of a lock
consisting of two plates hinged together one of said plates being secured upon the
rail A, at a distance back of its edges a, and a pin and eyes on the other rail to
.hold the other plate down, substantially as shown and described.
Dated this 8th day of November 1895.
