A New or improved Automa
EDWARD LEE GODFREY and WILLIAM COLBORNE BUTLIN both of Leonard
Stanley Stonehouse Gloucestershire trading as W. B. Winchcombe & Co. Engineers
do hereby declare the nature of this invention to be as follows:-
It is constructed in brass or other suitable material.
It is made in two parts; the one part being the bolt the other part being the
fastener.
The fastener is constructed by means of two or more supports or uprights on a
small base piece of any suitable material which base piece is about three inches in
length and one inch in width or any other suitable length or width.
These supports or uprights are about one inch in height and about half an inch
square and about half an inch apart the one from the other.
Through the centre of each support or upright, and cut from top to bottom is a
slot about one eighth of an inch in breadth or any suitable breadth cut lengthways
with the base so that each slot is in line with the other.
Within the slot of each upright or support and near the top is fixed a tumbler
or lever, revolving upon a pivot or axle fixed across the slot.
These tumblers or levers are made V shaped, about one eighth of an inch in
thickness, two inches in length and in breadth tapering from about one quarter of
an inch to about an inch and a quarter. They are so fixed within the slots that
the larger ends are on the outsides of the supports or uprights, the smaller ends
nearly meeting in the centre between the two supports or uprights, and are so
arranged that when the narrow ends are level in the centre in between the two
supports or uprights, the lower part of the larger ends is at the same time resting
upou the base, so as to make it an impossibility for the narrow ends to be
lifted up.
Within each slot and near the bottom is a small projection or stop which is so
fixed as to limit the revolution of the tumbler or lever so that on the larger ends
of the tumblers or levers being raised above the supports or uprights and coming
in contact with each other the smaller ends shall at the same time come in contact
with the stops or projections so as to prevent either tumbler or lever from falling
over towards the other, should only one be raised. The fastener can also be made
in the same manuer but with one upright or support and one tumbler or lever only
if desired.
The bolt is constructed by fixing on any suitable base similar to the base of the
fastener a short rod or piece, of metal or any suitable material fixed at right angles
to the length of the base, made V shaped about three eighths of an inch in breadth
at the base tapering to a point at the apex, and three eighths of an inch in height,
and in length about double the breadth of the base, or so suitably arranged in
length and shape that it will pass in between the two uprights or supports of the
fastener and underneath the points of the tumblers or levers when both fastener
and bolt are fixed in position.
Each of these is fixed in position by means of screws passing through holes
drilled in the base of both bolt and fastener as may be required.

page_text: We, EDWARD LEE GODFREY and WILLIAM COLBORNE BUTLIN, both of
Leonard Stanley, Stonehouse, Gloucestershire, Engineers 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:-
This invention consists of an improvement in automatic window fasteners and is
so constructed that the window can only be opened from the inside, while the act
of closing the window automatically operates the fastener and secures the window,
thus making it impossible to close the window without simultaneously fastening it.
The window fastener made in accordance with this invention is constructed of
brass or other suitable material, and is made in two parts, one consisting of the
bolt, and the other the automatic fastener. The fastener is made up of one or
more supports or uprights A. upon a small base piece of any suitable material B.
which base piece is about 3 inches in length, and one inch in width. These
measurements will of course be varied in accordance with the size of the window
in connection with which the fastener is to be used. The supports A. are about
one inch in height and about half an inch square, and about half an inch apart
the one from the other. Through the centre of each of these supports or uprights
is a slot about one eighth of an inch in breadth, cut lengthways, so that each slot
is in a line with the other. Within the slot of each upright or support, and near
the top, is fixed a tumbler or lever C. revolving on an axle or pivot D. fixed across
the slot. These tumblers or levers are shaped as shown in the accompanying
drawings. They are about one eighth of an inch in thickness, two inches in length,
and in breadth tapering from about a quarter of an inch to one and a quarter inches.
These are so fixed within the slots that the larger ends are on the outside of the
respective supports or uprights, the smaller ends nearly meeting in the centre.
They are so arranged that when the narrow ends are level in the centre between
the two supports, the lower part of the larger ends is at the same time resting
upon the base so as to make it an impossibility for the narrow ends to be
lifted up.
Within each slot at the bottom we fix a small stop E. which is so arranged as to
limit the revolution of the tumbler, so as to prevent either of the tumblers when
raised from falling over into the direction of the other, should only one be raised.
This fastener is attached by screws or any ordinary means to the inside of the
upper window sash, while the V shaped bolt F. attached by any suitable means to
the base plate G. is attached by screws or any other suitable means to the lower
window sash.
When it is desired to open the window, it is only necessary to raise both the
tumblers together, so that the broad ends meet in the centre. The narrow ends
are then free from the ✓ shaped bolt and the lower window sash can be raised.
The tumblers are then allowed to fall into their respective places. In closing the
window, the V shaped bolt descends on to the narrow ends of the tumblers, which
give way and allow the bolt to pass between them, then resuming their normal
attitude. It will then be found impossible to raise the lower sash without
operating the tumblers in the manner mentioned above.
Fig. 1. in the accompanying drawings is a plan of the window fastener
automatically closed.
Fig. 2. is an elevation view of the same.
Another form of this invention is shown in Figs. 3 and 4.
In this case only one
"tumbler is required, as shown in the accompanying drawings, Fig. 3. being a plan,
and Fig. 4. a side elevation of the same.

page_text: In this case a small base plate H. is connected to the upper window sash by
screws or other suitable means. To this are attached two uprights I. connected
by a pivot or axle J. on which axle hangs the tumbler K. On the lower sash is
attached a metal base plate L. bent up ou the inner side as shown in the accom-
panying drawings. This is attached to the lower window sash by rivets, screws, or
other suitable means.
To operate the fastener in this case, it is necessary to pull forward the tumbler
with one hand so that the narrow end disappears between the two uprights. The
lower sash can then be raised freely, and the tumbler allowed to fall back into its
normal position. In closing the window, the sash in descending will itself push the
narrow end of the tumbler back until it has passed. The tumbler will then resume
its normal position, and it will be found that the window can not be opened until
the tumbler has been operated as described above. Between the two uprights
there is placed a small catch as shown on the dotted line M to prevent the tumbler
from falling forward in the direction of the lower window sash.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. An automatic window fastener, consisting of a fixed bolt on the one sash
in connection with two tumblers with the uprights forming the fastener, substan-
tially as described and shown in the foregoing Specification and drawings.
2. An automatic window fastener consisting of the tumbler K. with the
supports I. and attachments, substantially as described and illustrated in the
foregoing Specification and drawings.
3. An automatic window fastener substantially as described and shown in
the foregoing Specification and drawings.
