PROVISIONAL SPECIFICATION.
Improvements in Window Fasteners.
We, JAMES TAYLOR of 22 Anglia Grove, The Willows, Rumworth, Bolton,
Painter, and ISAAC EARNSHAW of 32 Bottom-oth-Moor, Ainsworth near Bolton,
Painter, both in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:-
This invention relates to improvements in window fasteners and is designed to
prevent the same being opened from the outside by means of knives or other
instruments that may be pushed or passed between or through the joint of the
window frames. This we carry into effect by providing a metallic projection or
plate with a hole or slot in which drops the end of a pin loosely mounted in the
tail end of the locking bar of the fastener. This pin is fitted with a stop to allow
of the same being lifted sufficiently to clear the upper side of the metallic
projection or plate, after which the locking bar may be swivelled in the usual
manner. The upper end of the loosely mounted pin is fitted with a knob or other
projection to allow of the same being operated or handled from the inside.
Dated the 12th October 1893.
COMPLETE SPECIFICATION.
Improvements in Window Fasteners.
We JAMES TAYLOR, of 22 Anglia Grove, The Willows, Bolton, in the County
of Lancaster, Painter, and ISAAC EARNSHAW, of 32 Bottom-oth-Moor Ainsworth,
near Bolton, in the County of Lancaster, Painter, 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 improvements in window sash fasteners and in order to
explain more clearly our invention we have appended hereunto an illustrative sheet
of drawings, upon which are figures and numbers of reference, similar numbers
referring throughout the several views to the same thing or part.
Fig. 1, is a plan view of a sash fastener made according to this our invention.
Fig. 2, is a part plan showing more particularly the lever and its spring.
Fig. 3, is a sectional view on line A-B of Fig. 1.
4, is the upper sash to which is secured the plate 5, upon which is carried the
arm or lever 6, which turns about the pin 7, and operated by means of the knob or
handle 8. At the inner end of the lever 6, is pivoted the antifriction roller 9,
which impinges upon the spring 16 which latter is rivetted to the upright part 11,
of the plate 5. The lever 6, is so shaped at 12, that when in its closed position as
seen in Figs. 1 & 2, it shall abut against the outstanding part 13, of the plate 5.
The front end of the lever 6, is made to receive the vertical sliding pin 14, having
the collar 15, between which and the upper part 16, is placed the spring 17, whose
tendency is always to force downwards the point 18, of the pin 14, but which may
be raised at will by the knob 8. 19, is the bottom sash upon which is secured the
plate 20, carrying the curved arm 21. This arm is dovetailed in sectional shape
and fits into or is embraced by the corresponding recess 22, in the lever 6. Instead
of being dovetail in shape however, it may be of other suitable form. In this

page_text: plate 20, is a hole or recess 23, into which the point 18, is pushed when in its closed
position.
Its action is therefore thus:-In order to unfasten the window, the knob 8, is
raised until the point 18, is clear of the hole 23, when the lever may be pushed
back upon the plate 5, and clear of the front sash.
When fastening the window, the lever is drawn forward in the usual manner until
it assumes the position shown in Fig. 1, when the point 18, as before stated is
pushed into the hole 23, by the spring 17, and thereby locked.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In window fasteners the combination with the plate 20, having the recess or
hole 23, of the lever 6, having the sliding pin 14, with its point 18, and spring 17,
and carried upon the plate 6, with roller 9, and spring 10, all constructed and
operating as herein described and illustrated upon the drawing.
