Improvements in or in connection with Fastenings for Doors,
Windows, Gates; and the like.
1, WILLIAM WORRALL, of 75. Endell Street, Bloomsbury, Artist in Stain'd
Glass, and Décoration, do hereby declare the nature of this invention to be as
follows:-
:-
A steel spring, made preferably of half round section, or other segment of a
circle, having its flat side rivited at one end to the catch plate of bolt, latch, or
other inside fastener, the loose end being turned upwards, forming the spring,
which has a sunken indent, or lip, about the place where the action of the bolt,
lever, or latch, usually ends, each of these having a protruding lip at its end, or
side, which, on the fastener being push'd to its extremity, engages with the sunken
indent, aud cannot be released until the free end of the spring is press'd down.
Fasteners may be made of new forms, or the principle can be applied to almost any
existing inside fasteners.

COMPLETE SPECIFICATION.
Improvements in or in connection with Fastenings for Doors,
Windows, Gates, and the like.
1, WILLIAM WORRALL, of 75, Endell Street, Bloomsbury, Artist in Stain'd
Glass, and Decoration, do hereby declare the nature of this invention and in what
manuer the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
A in all the figs. on the sheet of drawings is a steel spring, formed of half
round, cliptic, or other sectional shape, and of a strength, to suit the various
requirements, of the several fastenings. The flat side of the said spring should be
rivited at one end, to the catch, plate of latch, bolt, window, or other fastener, a
lip being cut or formed on the round or upper side of the spring, at the exact spot
where the action of the latch or bolt ends. The spring, being bent upwards
slightly, at its free end, opposes sufficient pressure to hold securely, the bolt or
latch, on its being push'd along, the upper surface of the spring, and engaging, with
the sunken lip, which may be made to engage entirely with the fastener, as
in Fig. 1, or by an opposing lip, at the end or side of the bolt, or other fastener.
Such opposing lip may be formed by cutting away part of the underside of the
bolt, leaving a lip at the end as in Fig. 3, or by cutting a fluted groove on the
under side of a latch, leaving a lip at either side desired.
To add to the play and strength of the spring, a sunken indent B, may be made, or
a slot, cut entirely out according to the thickness of the catch plate, for the spring
to sink into, when press'd down from its free end, by which action the bolt, latch or
other fastener is released, and set free. Fig. 1, is an ordinary window fastener in
common use with the spring A, and the indent or slot B, shewn therein. Fig. 2, is
also a latch in common use, with a lip at the end, left by filing away as much of
the bolt from the underside as may be desired. Figs. 4 & 5, are for use as door,
or window, fasteners, new designs for which can be multiplied, as to outward form,
to any extent, but all with the spring and slot arrangements, as described and sliewn
herein.

page_text: 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 or improvement is,
The application of the spring and sunken indent, or slot, or opposing lip, to any,
or all inside fastenings as at present made and in common use, or to any other new
or varied shape, which may he designed, and suitable for the application of the
spring, &c., &c., &c., all as described and shewn herein.
Dated this 6th day of February 1892.
