JOSEPH JONES of 7, Crawford Terrace Grenville Street Ashton-under-Lyne,
Mill Manager, JOHN RAWSON Carpenter 198 Park Road Tame Valley Dukinfield
do hereby declare the nature of this invention to be as follows :-
In carrying out our invention we employ two principle methods; the rack &
pinion or the lever. Our chief object being to enable the opening of windows for
ventilation or other purposes. At the same time they shall be fastened when
opened, similarly to when closed. Also the prevention of shaking or rattling; we
further protect the fastener against being shot back, with a knife or other instru-
ment. In employing the rack & pinion, the latter is suitably mounted & geared
into 2 racks, when the pinion is turned, the racks move either outwardly together,
or inwardly; & being provided with forked extremities, may engage in any of the
holes of the plates, a pair of which are attached to the stationary & another pair to
the movable parts of the windows.
A modification of the above is the employment of a lever with rods in connection
therewith.

Improvements in and in connection with Window Sash Fasteners.
JOSEPH JONES, 7 Crawford Terrace Ashton-under-Lyne in the County of
Lancashire Mill Manager, and JOHN RAWSON, 198 Park Road Tame Valley
Dukinfield in the County of Cheshire, Joiner, 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 :-
Our invention has reference to a new or improved mode of, or construction and
arrangement and combination of parts or mechanism for locking the sashes of
windows in any position in which they may be placed; and to prevent, or allow the
sashes being either raised or lowered; also combining such parts or arrangements
for enabling the sashes to be opened at top or bottom to allow ventilation of the
rooms where applied, and at the same time to be securely fastened. To stop
rattling of sashes and provide a catch or catches or other means to prevent
the bolts being shot back.
In carrying out our invention we employ two methods, the first being an arrange-
ment of levers having forked extremities, worked from a central one; the other is
It consists essentially
the method we prefer to use and which we do now describe.
in suitably mounting two racks with forked extremities at one end, namely that
furthest from the rack. The racks are placed about the centre of the top portion
of the bottom sash, and each gears into a small pinion, on opposing sides.
The pinion carries on its axis, a projection or thumb-bit by which to operate the
apparatus. The said racks which form a double bolt, lie flatwise on the bottom
sash and are free to slide horizontally controlled by the slots they contain and
the screws which pass through them into the sash also keep the apparatus in
position.
Each extremity of the racks what we may term the bolt points, is provided with
a suitable bracket containing a number of holes any of which they may be made to
enter according as they are either open or closed.

page_text: The said brackets are fixed the one pair on the beads, and the other on the right
and left hand bottom corners of the top sash.
There is no fixed length or number of holes these brackets are to contain, and
may vary to meet circumstances.
Fig. 1. is an elevation of window with apparatus fixed.
Fig. 2. is a plan of same.
Fig. 3. is a plan showing bolt disengaged and pulled back to allow top and bottom
sashes to pass each other for such purposes as cleaning &c.
Fig. 4. is a side elevation showing thumb-bit and pinion with their carrying
bracket.
Fig. 5. is a side elevation showing the catch and its bracket.
Fig. 6. is a plan and side elevation of top sash brackets.
Fig. 7. is a plan and side elevation of bottom sash brackets.
The invention will be fully described by aid of the accompanying drawings above
referred to.
The thumb-bit A carries at its lower end, a spindle or shank forming the axis
for small pinion P to revolve on bearings in fixed brackets A' see Fig. 4. The
pinion P, on being caused to turn, gives through gearing with teeth of racks B, a
longitudinal motion to C, which may be utilised to either fasten or unfasten the
sashes J and H or their equivalents; by say shooting the forked extremities
of C, C represented by D 123 of Fig. 2 into holes of suitable small brackets E123
of Fig. 2. Enlarged views of the latter are shown in Figs. 6 and 7.
The points D123 which we will call hereafter "bolts" are guided to or away
from the holes of their respective brackets by means of the straight slots F, and the
screws G which pass through them as shown.
The small brackets E173 vary
in length and number of holes they contain.
E and E are secured to the beads I of the casing, in such position as to allow the
bolts D and D³ to easily enter their lowest holes when the sashes are shut.
Also E and E' must be so fixed at the bottom left, and right hand corners of the
top" sash, that their bottom holes will with ease admit the bolts D' and D².
The use of the brackets E123 is to avoid injury to the casing or sashes, and to
prevent the windows being opened from outside.
To allow either or both sashes to be opened for such purposes as ventilation;
and to effect this the lifting of the bottom sash J carries with it the parts secured
to it by the screws G.
First turn the thumb-bit A and withdraw the "four" points or bolts. The
bottom sash may then be raised to a height, and the top lowered to a level which
will allow the bolts D 123 to come opposite and enter E128 when A is turned the
reverse way.
Thus in this position the sashes are both open, and yet as securely fastened as
when closed and fastened.
The manner in which our invention entirely prevents rattling or shaking of
windows will be now described. It will be observed that the whole apparatus is
held as if stationary to the bead I, whilst in action. It is thus impossible for any
movement in the sashes to take place. For I being a fixture and E screwed to it,
and D entering E; D being part of C, the screws G pass through slots F and
fasten into sash J, it is clear that no movement can take place in it or its
equivalent.
It has been shown that C does not move and D¹ a part of it entering E' which
latter is secured to top sash, it follows that there is no rattling takes place in the
top" sash or its equivalent.
To prevent the fastener against being shot back, a catch K Fig. 5 is mounted in
a fixing L screwed to J as shown in Figs. 1 and 2. Fig. 3 shows K thrown back
when not in action; when in action K enters the hole M, and fixes C when in the
fastened position.
In order to allow each sash to pass the other for cleaning or other purposes, we
furnish a slot Fat right angles to slot F. The thumb-bit A given an extra turn

page_text: will permit the screws G to enter the slots F' by gently pulling C toward the
operator. The apparatus then assumes the position shown by Fig. 3. "one half only
being shown." D it will be observed does not now project over the bottom sash J
as in Fig. 2.
The open slot or slots at extremities of C, go readily into position after with-
drawing them. They are for the purpose of strengthening the fastener.
A modification of our invention consists of dispensing with the racks, and
shortening C; retaining our slot which may be "angular or curved " as desired,
inserting a second slot of straight or "other" form, thus by providing each with a
catch we get a simpler arrangement, yet possessing similar advantages to the one
more fully described.
This modification we show in dotted outline Figs. 1 and 2, at least that portion
differing from what has already been described.
The manner in which we apply the same is clearly shown, and is as follows.
In Fig. 2 at Y the connection is made between the dotted part and the bolt C.
Having previously described the latter we will now only explain the dotted ontlines.
The straight or preferably cranked part is slotted at F' either as shown "straight
or curved; it also carries a projecting snug N to engage with a catch R when the
bolt is shot.
"
The screw G is for the same purpose as G, herein before described. A vertical
projection O, is provided to act as thumb-bit to operate the invention as described
or their equivalents.
This modification is applied in pairs and the above description will serve for both
right and left hand sides alike.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1st. The double bolt C forming a quadruple sash fastener, by entering four parts
which will securely hold them, or as described a separate pair of bolts one fixed at
each side. These or their equivalents.
2nd. A. slot formed at right or other angle, or if prefered curved, for the purposes
herein before described.
3rd. The herein before described methods of securing window sashes or the like
substantially as and for the purposes herein set forth.
