PROVISIONAL SPECIFICATION.
Improved Means for Opening, Closing, and Fastening Window
Sashes.
I SAMUEL MCKEE BARRY of 16 Upper Thames Street, London, E.C.,
Merchant, do hereby declare the nature of this invention to be as follows:-
Felt
The object of the present invention is to provide means whereby the opening
and closing of the top sash of windows is facilitated, and also to provide, in
connection therewith, a fastening device which will be more secure than heretofore.
The opening and closing of the top sash is, according to my invention, facilitated
by the employment of a rod which is connected with the fastening device on the
top sash, and stands up vertically when the fastening is open or ready to open, and
lies down when the fastening is locked.
The fastener to which this rod is attached has the catch or bolt, which extends
across the division of the sashes, made in two parts, jointed together with an elbow
capable of bending in one direction only. One portion is fitted into a sleeve on
the window sash, and has a limited rotary movement therein. The other portion,
which has a groove cut in it, to engage with, and grip, so as to prevent the
window rattling, an engagement plate on the other sash, may be in line with the
other part, so as to fasten the window; or it may be bent at right angles out of
engagement with the plate.
It will be understood that as the elbow joint of the bolt can bend only in one
direction, the position of the bolt in its sleeve must be such as to permit the elbow
joint to work when it is required to fasten or unfasten the window. When,
however, the fastening has been effected, the partial rotation of the bolt in its
sleeve will prevent the disengagement of the bolt, by bringing the joint into an
inoperative position. The rotation of the bolt back to its former position will free
it, and enable the joint again to be operated.
The rotation of the bolt is effected by the rod above mentioned, which is screwed
into it through a slot in the sleeve, the slot being of such length as to permit the
requisite degree of rotation, say, a quarter turn.
The action of the device is as follows:-Supposing the window to be locked,
the rod will then be in its horizontal position. To unlock the sashes, the rod is
raised to the vertical, so as to permit the joint of the lucking bolt to be operated.
Once free, the upper sash may be depressed by the upstanding rod (or a pair of
rods may
be employed), and again the sash may be raised by the same means.
Instead of the rod above mentioned, a thumb screw or butterfly nut may be
attached to the bolt, if preferred, for the purpose of rotating the latter.

SAMUEL MCKEE BARRY 16 Upper Thames Street London E.C. Felt
Merchant, 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 :-
The object of my invention is to provide means whereby the opening, and closing
of the top sash of windows is facilitated, and also to provide in connection therewith
a fastening device which will be more secure than heretofore.
The opening and closing of the top sash is according to my invention facilitated
by the employment of a rod which is connected with the fastening device on the
top sash, and stands up vertically when the fastening is open or ready to open, and
lies down when the fastening is locked.
The fastener to which the rod is attached has the catch or bolt which extends
across the division of the sashes, made in two parts jointed together with an elbow
capable of bending in one direction only. One portion is fitted into a sleeve on
the window sash and has a limited rotary movement therein. The other portion
which has a groove cut in it to engage with a grip so as to prevent the window
rattling an engagement plate on the other sash, may be in line with the other
part, so as to fasten the window; or it may be bent at right angles out of
engagement with the plate.
It will be understood that as the elbow joint of the bolt can bend only in one
direction, the position of the bolt in its sleeve must be made as to permit, the
elbow joint to work when it is required to fasten or unfasten window. When,
however, the fastening has been effected, the partial rotation of the bolt in its
sleeve will prevent the disengagement of the bolt, by bringing the joint into an
inoperative position, the rotation of the bolt back to its former position will free
it, and enable the joint again to be operated.
The rotation of the bolt is effected by the rod above mentioned, which is screwed
into it through a slot in the sleeve, the slot being of such length as to, permit the
requisite degree of rotation, say, a quarter turn.
The action of the device is as follows-Supposing the window to be locked, the
rod will then be in its horizontal position.
To unlock the sashes, the rod is raised to the vertical, so as to permit the joint
of the locking bolt to be operated. Once free the upper sash may be depressed by
the upstanding rod (or pair of rods) and again the sash may be raised by the same
means.
Instead of the rod above mentioned a thumb screw or butterfly nut, may be
attached to the bolt, if preferred, for the purpose of rotating the latter.
In order that my invention shall be more readily understood and carried into
practical effect I have hereunto annexed 3 sheets of drawings and I will now
proceed to demonstrate the working with the assistance of same.
Figure 1 represents invention when the window is closed and fastened.
Figure 2 shows the arm A in an upright position which allows of the bolt D
being turned back and the window to be opened, the arm can then be depressed when
the top sash of window will go down. When the sash is required to be raised the
same means can be used.
If arm A is cut short and cap B is put at C this forms an improved window
fastener.
Figure 3 shows bolt D when pushed back and also grip F. which I have since
added as an improvement to my Provisional Specification and which I will now
describe it consists of a piece of sheet brass bent up at one side so as to engage into

page_text: groove E when window is closed, groove E is cut out of bolt Danu part
nade to allow of going freely on F when arm A is lowered it turns bolt round where
groove is smaller and tightens on to thus preventing vibration and window
rattling.
The elbow of bolt D is so made that it can only be moved when arm is upright,
thus making a perfect lock which no burglar could push back by putting his knife
up between slit of sashes.
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
1. I claim an improved means for putting down or pulling up top sashes of
windows.
2. I claim un improved window fastener which is burglar proof and so constructed
that it will prevent vibration and rattling.
3. A combination of the above two claims.
