PROVISIONAL SPECIFICATION.
Improvements in Window Sash, Casement, and Door Fasteners,
and the like.
I, SAMUEL JAMES WISEMAN of 15 Above Bar, Southampton in the County
of Hants, Fine Art Dealer and Picture Frame Maker, do hereby declare the
nature of this invention to be as follows:-
My invention relates to a fastener for window sashes, casements, doors, and
the like.
The main object of my said invention is to provide a simple and durable fastener
for use upon window sashes, casements, doors, and the like, so that they can be
opened to a limited extent for ventilating purposes, and yet remain locked from
the inside while in the more or less open position.
I will describe my invention as applied to window sashes.
In making any improved fastener, according to one form or modification of my
invention, I secure a metal plate upon the top of the meeting bar of the outside
sash so that the long leg of the 1 plate stands vertically above the meeting bar.
Upon the top of the meeting bar of the inside sash I secure a device which
consists of a flat plate turned up at the inner end, and grooved lengthways to the
extent of its flat part, into the groove I fit another flat plate so that it can be slid
backwards and forwards in the groove.
Upon the top part of the vertical, or long leg, of 1 plate I pivot a headed bolt,
the free (headed) end of which can be brought forward towards the inner sash, but
the bolt is prevented from being hinged back into a position more than perpen-
dicular by means of a stop provided on the plate.
A longitudinal slot of a limited length is formed in the top of the sliding plate
and a stud is passed down through the said slot and secured to the fixed plate, the
stud is screw threaded and a screw nut is provided upon the same which can be
screwed down, and partly into, the sliding plate so as to fix it in the locked position,
that is, when it is slid back over the outer sash bar, a longitudinal slot is also
formed in the sliding plate at the outer extremity of same to allow of it being slid
back over the vertical leg of the 1 plate, the said slot finishes in a circular hole
formed in the sliding plate to take the pivotted bolt us, and for the purpose herein-
after described.
The normal position of the pivotted bolt when the window is closed, is a
horizontal or, approximately horizontal one, and the inner or free end of bolt then
rests in a recess formed in the turned up end of the fixed plate, provided on the top
of the meeting bar of the inner sash; and the inner end of bolt may be secured to
the fixed plate, in the turned up end aforesaid, by means of a screw nut provided
on the extremity of the inner end of bolt-which when screwed up to the turned
up end of the fixed plate fixes the inner end of bolt in same and consequently
prevents any up and down movement of the sashes.
Taking it that the fastener is in the locked position and it is desired to open the
sashes the inner end of bolt is released from its engagement with the fixed plate,
the outer sash may then be pushed down, or the lower one lifted, to a limited
extent, that is until the pivotted end of bolt comes in contact with the sliding plate,
but should it be desired to further open the sashes, the pivotted bolt is raised into
a perpendicular position, and then the outer sash may be pushed down, or the inner
one raised to an extent, limited only by the length of the said bolt, that is to the
head of same, the bolt working up and down in the circular hole hereinbefore
referred to, formed in the end of the sliding plate.

page_text: .
Should it be desired to open the outer or inner sashes to their utmost limit the
sliding plate is brought forward clear of the bolt, when the sashes can be opened
fully or to any desired extent.
An important feature of my invention is, that I can open the sashes to a limited
extent for ventilating purposes and yet same will be locked from the inside in the
more or less open position.
In the case of French casements, doors, and the like, the plates referred to,
together with the hinged bolt, projections, and other necessary attachments or
connections as before described, would, to suit these circumstances, be suitably
disposed although in a similar manner as herein before set forth.
Dated this 16th day of December 1893.

COMPLETE SPECIFICATION.
Improvements in Window Sash, Casement, and Door Fasteners,
and the like.
1, SAMUEL JAMES WISEMAN, of 15, Above Bar, Southampton, in the County
of Hants, Fine Art Dealer and Picture Frame Maker, 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 :—
My invention relates to a fastener for window sashes, casements, doors, and
the like.
The main object of my said invention is to provide a simple and durable fastener
for use upon window sashes, casements, doors, and the like, so that they can be
opened to a limited extent for ventilating purposes, and yet remain locked from
the inside while in the more or less open position.
In the accompanying drawings
Fig. 1. is a side view of my improved fastener adapted for use upon window
sashes, the latter being shewn in cross section, this view shews the fastener in
position so that the window can be opened to a limited extent.
Fig. 2, is a plan on top of Fig. 1.
Fig. 3, is a plan view of Fig. 1, at and below the line a. a.
Fig. 4, is a side view of the window fastener in the locked position.
Fig. 5, is a plan on top of Fig. 4.
Fig. 6, is an end view in elevation of Fig. 4.
Fig. 7, is a side view shewing one position the fastener will be in when the window
is partially opened but locked.
Fig. 8, shews in front elevation another form or modification of my fastener
adapted for use upon a door B', the fastener being in the engaged or locked
position, that is, so that the door can only be opened to an extent limited by the
length of the bolt A².
Fig. 9, is a plan on top of Fig. 8, the part of door and door frame being shewn
in section.
Fig. 10, is a front view in elevation shewing the fastener in the unlocked or
disengaged position, so that the door can be opened to its fullest extent.
Fig. 11, is a plan on top of Fig. 10, the part of door and door frame being shewn
in section.
Like letters indicate corresponding parts throughout the drawings.
I will first describe my invention, with reference to Figs. 1, to 7, as adapted for
use as a window fastener.
Upon the top of the meeting bar A", of the inner sash I secure a metal plate C,

page_text: turned up at the inner end C³, and grooved lengthways to the extent of its flat
part, into the groove I fit another plate D, so that it can be slid backwards
and forwards in the groove being handled by the knob D'.
On the top of the vertical leg A', of the plate A, I pivot a bolt A³, the free
end of which can be brought forward, but the bolt is prevented from being
hinged back into a position beyond the perpendicular by the stop b, and the bolt
can be temporarily fixed in the vertical position by pushing it down so that it will
be jammed in the recess c, formed in the top of the vertical leg A³, an angled
recess or slot, being formed in the bolt for the purpose, to this end a slotted
pivot hole e, is provided in the leg A¹, which will allow of a limited vertical travel
of the bolt A. To release the bolt it is only necessary to lift same clear of the
recess c.
A longitudinal slot h, of a limited length is formed in the top of the sliding
plate D, and a stud e, is passed through same and fixed in the plate C, the head of
stud is screw threaded and a screw nut e', provided, which upon being screwed
down on to the plate D, and partly into the slot h, in the sliding plate D, fixes it in
any desired position lengthways in relation to the plate C, a longitudinal slot f, is
also formed in the end of the sliding plate D, which finishes in a circular hole f¹,
which takes the bolt A³, as and for the purpose hereinafter described.
The action of the whole is as follows:-
When it is desired to fasten the window when closed the bolt A', is brought
forward into the position shewn by Figs. 4, 5, and 6, the head or free end of bolt
then rests in a recess K, formed in the turned up end C', of the plate C, and the
head of bolt is secured in this recess to the plate C, by screwing up the nut E, on
to the end C, of the plate, the bolt A2 also rests on the head of the stud thus any
movement of the outer sash, either vertical or horizontal is prevented.
or
e,
When it is desired to open the window to a limited extent the bolt A³, is released
from its aforesaid engagement with the plate C, and the plate D, is pushed back,
the outer sash may then be lowered and the inner one raised to a limited extent,
that is, until the pivotted end of the bolt A', comes in contact with the end of the
plate D, (see Fig. 7,) but should it be desired to further open the sashes, the
bolt A³, is hinged back into a vertical position (see Fig. 1,) and then the outer
sash may be lowered and the inner one raised to an extent liniited only by the
length of the bolt A², that is to the head g, of same, the bolt working up and down
in the circular hole f', but should it be desired to open the outer and inner sash
to the utmost limit, the sliding plate D, is brought forward clear of the bolt A³, the
sashes can then be opened fully or to any desired extent.
Figs. 8, 9, 10, and 11, shew my invention adapted for use upon hinged doors, the
various plates being similarly combined with but very slight modification, and
suitably disposed to meet the somewhat altered circumstances.
Figs. 8, and 9, shew, in elevation and plan respectively, the position in which
the plates C, and A, are secured to the door and door frame respectively, and the
position in which the sliding plate D, will be placed when it is desired to open the
door to a limited extent, and yet keep it locked; the plate D, will in this case be
pushed forward and secured by the screw nut e', in that position, and the extent to
which the door can then be opened is limited by the length of the bolt A³, to the
head
9, of
same, the end of the sliding plate D, then coming in contact with the
head of the bolt, thus preventing the door being further opened.
When it is desired to unlock the door the sliding plate is pushed back (see
Figs. 10, and 11,) and the door can then be opened to any desired extent. In the
locked or engaged position the sliding plate D, is in engagement with the bolt A², but
free to travel lengthways of same as the door is opened and shut, the bolt working
in the hole f, and hinging where pivotted to suit the various angles to which the
door is opened, the fully opened position of door where locked is shewn in dotted
lines in Fig. 9. But when the door is closed the sliding plate D, can be pushed
back into the position shewn at Figs. 10, and 11, the slot, permitting of same.

page_text: 1 may sometimes provide one or more notches d, d, at the underside of the
bolt A, one notch close to the head g, of the bolt, and when the fastener is in the
locked position and the door is opened the bolt will drop over the sliding plate when
it comes in contact with a notch, thus engaging with same and therefore keeping
the door in the desired open position and preventing it from swinging about.
In the case of French casements, and the like, the plates referred to together
with the hinged bolt, projections, and other necessary attachments or connections
as hereinbefore described, would to suit the circumstances be suitably disposed in a
similar manner as herein before set forth.
An important feature of my invention is that sashes, doors, and casements--to
which my fasteners are fitted-can be opened to a limited extent for ventilating
purposes, and yet the same will be locked from the inside in the more or less open
position.
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 is :-
1st. The improved fastener for windows, doors, and casements, consisting of the
parts constructed, arranged, and combined substantially as herein before described
with reference to the accompanying drawings, and operating as and for the purpose
.above specified.
2nd. The hereinbefore described improved apparatus, by means of which window
sashes, doors, and casements may be opened to a limited extent (the sashes either
at the top bottom,) and yet remain locked so as to prevent them from being
opened to any considerable extent from the outside.
and
or
3rd. The combination of parts comprising the plates A, C, and D, and the
bolt A³, and the other parts of my apparatus arranged to act as and for the purpose
above specified.
