page_text: JOHN LAW, Darwin Street, Birmingham, in the County of Warwick, Painter, and
JAMES ALFRED CRANE, 43, Villa Road, Handsworth, in the County of Stafford,
Modeller, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable the sash or sashes to be securely
fastened at any required distance from the top or bottom of window, and at the
same time to answer the purpose of an ordinary sash fastener by securing the two-
sashes in the usual position.
To accomplish this result we make a bolt of a crank formation, secured to a
plate in the lower sash by a swivel action, the overhanging part of the bolt having
a pointed nose bit formed at right angles, which takes into a notch or notches in
the window frame at convenient distances.
We also form the usual knob for putting a sash fastener in operation, with a
swivel action, and carrying a tab below the level of the bolt, which fits into a slot
in the plate by pressing the knob sideways, thus locking the nose or point of bolt
into the notch in the window frame. The bolt can be freed for withdrawal by
reversing the action of the knob.
The parts are made reversable by withdrawing the swivel screws, when two
fasteners are required on the same window, thus avoiding the necessity of keeping
two kinds of stock.

DESCRIPTION OF THE DRAWINGS.
Figures 1 & 2 represent respectively' the general plan of the sash fastener in
conjunction with the window frame and shewing the crank bolt before & after
taking into the notch. a represents in section the pulley style. b is the upper
surface of the lower sash top rail. c is the plate of fastener. d represents in
section the upper sash style. e. is the crank bolt and g the notch into which
it takes.
Figure 3, represents in plan the portion of plate c shewing the slot g.
Figures 4 & 5 represent in side elevation parts of crank bolt e and plate c.
Letter h is the knob, i is the tab, j is the swivel pin, and the dotted line indicates
the slot g, Figure 4 shews the position of knob before locking and Figure 5, shews
the position of knob after locking.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. A sash fastener provided with a crank bolt and taking into notches made at
suitable intervals in the upper sash style substantially as drawn and described.
2. A sash fastener with a locking arrangement substantially as drawn and
described in Figures 3, 4, and 5.
