PROVISIONAL SPECIFICATION.
Improvements in Fastening Means for Doors,. Windows; or the like.
I; ROBERT GRIMMER; of 36 Lynn Road, Wisbech,, in the County of Cambridge,
Hay and Straw Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described' and' ascer-
tained in and by the following statement:-
This invention relates to. improvements in fastening means for. doors, windows,
or the like, and in accordance therewith I provide a metal angle ring which. is
tapped or internally screw-threaded,, such, ring, being, adapted to be screwed or
otherwise fixed to either side of a door or the like,, or to the jamb or other con-
venient portion of the frame work of same..
A screw-threaded disc fits and turns within the tapped ring aforesaid. which disc
is provided with a bolt to which is fixed or formed integral therewith; a suitable
handle.
The bolt is preferably fixed to the disc and the handle by means of a. headed
pin which passes through a longitudinally disposed slot in the said. bolt, whereby
the latter is allowed an independent longitudinal movement.
A catch is provided upon. the disc to engage the rear end of the bolt.
In operation the movement of the handle causes the bolt to shoot forward or
backward (according to the direction-in which the said handle is turned) and by
means of the catch provided for the purpose upon the disc acting in conjunction
with the slot and-screw-threads, ample pressure is brought to bear upon the bolt
to exclude any draught or the like finding its way through the door, for instance,
or to prevent the insertion of an instrument in rabbeted. joints of doors, windows
casements or the like.
In lieu of the arrangement above described I may provide a ring (tapped or
otherwise) within which fits and works a disc provided with a. handle and bolt.
The said handle and bolt may be formed integral if desirable.

I, ROBERT GRIMMER, of 36 Lynn Road, Wisbech; in the County, of Cambridge,
Hay and Straw Merchant, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in fastening means for doors, windows,
or the like, and by the use of same the bolt or other fastener not only securely
fastens the door, or window, but presses same firmly into the closed position so as
to exclude draught and to prevent the insertion of a knife blade or other like
instrument in the joints.
And in order that this invention may be fully understood I will describe same
with reference to the accompanying drawings and to the letters and figures of
reference marked thereon.
Fig. 1 is a front elevational view of the fastening means constructed in accord-
ance with this invention shewn as applied to an ordinary door.
Fig. 2 is a plan view of the same, and
Figs. 3 and 4 are respectively a section of the ring in which works the fastening
device, and a view partly in section of the fastening bolt and its carrier.
Figs. 5 and 6 are face views respectively in the closed and open positions of a
modification of the fastening means drawn to a smaller scale than the preceding
figures. Similar letters of reference indicate like parts throughout the figures.
In carrying my invention into effect I provide an angle ring of metal or other
material a tapped or screw-threaded internally as shewn particularly in Fig. 3
which is let into, and screwed so that its face is flush with, the side of a door or
the like, or it may be applied to the jamb or other convenient portion. of the
frame-work.
A disc 6 having an externally screw-threaded neck c see particularly Figs. 1, 2,
and 4, fits and turns within the tapped ring aforesaid and to this disc is attached
the fastening bolt (see also Figs. 1, 2, and 4).
A handle e is provided for actuating the bolt which may be hinged or pivotted
to the pin f as shewn, which pin passes through the disc and the bolt and secures
the two together, a nut g (see Fig. 4) or other means being employed to hold them,
or the handle may be otherwise fixed or it may be formed integral with the disc.
In operation the turning of the handle from one side to the other (the stops h
regulating the amount of travel possible) causes the bolt to turn either over the
edge of the closed door, as shewn in full lines, Figs. 1 and 2, or away from
same, as shewn in dotted lines Fig. 1.
The disc bc being screw-threaded within the ring a will when turned for
fastening the door be screwed deeper within said ring a causing the bolt to exert
considerable pressure upon the edge of the door and tightly hold it against the
door post or frame and prevent any draught finding its way through the joint.
In the modification shewn in Figs. 5 and 6 the invention is shewn as applied
to a draw bolt fastener in which the bolt takes into a striking plate. To permit of this
the bolt d is formed with the longitudinally disposed slot i through which passes
a headed pink whereby the bolt is allowed an independent longitudinal move-
ment. A catch is provided upon the disc which engages with the end of the
bolt d, into which the end of the bolt a falls when said bolt is withdrawn from the
striking plate. The catch 1, pin k, and slot in sleeve e serve to hold the bolt in
position. Though the handle is shewn only upon one side of the door it will be
obvious that two handles, one upon each side, may with equal facility be employed.
The sliding bolt above described is provided with an ordnary knob, not shewn
in the drawings) working in a slot provided in the outer disc and by which longi-
tudinal motion is given for engaging and disengaging with the striking plate.
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. The improvements in fastening means for doors, windows, or the like, sub-
stantially as herein before described and shewn in the drawings.

page_text: 2. In fastening means for doors, windows, or the like, constructing the bolt
carrier with a screw-threaded periphery working in an internally screw threaded
casing or ring so that upon turning the bolt carrier so that the bolt may engage
with the door or window and hold same closed the bolt is lowered or depressed and
exerts pressure upon the edge of such door or window and fixes same tightly in
position so as to exclude draught and dust.
3. In fastening means for doors, windows, or the like, the internally screw-
threaded angle ring a; disc b; with externally screwed neck c; bolt d; handle
or handles e; and stops h; all constructed arranged and operating substantially
as and for the purposes hereinbefore described.
4. In fastening means for doors, windows, or the like, the internally screw-
threaded angle ring a; the disc b; with externally screwed neck c; the bolt d;
handle or handles e; stops h; the slot i in bolt; pin k; and catch ; all con-
structed, arranged, and operating substantially as and for the purposes herein-
before described.
