PROVISIONAL SPECIFICATION.
Improvements in the Method of Securing Window Sashes when
Closed or Partially Closed and in Appliances used in connection
therewith.
JOHN HENRY LYON, Gas Works Lessee and Manager, The Retreat, Salisbury
Road, Cosham, in the County of Southampton, do hereby declare the nature of this
invention to be as follows:-
"Improvements in the method of securing window sashes when closed or partially
closed and in appliances used in connection therewith" and in what manner the
same may be performed is described and ascertained in the following statement.
To facilitate the describing of my invention reference is necessary to the accom-
panying drawings.
This invention has for its object more particularly the fastening of window sashes
when it is desired to leave them partially open for the ventilation of the room or
rooms, at the same time the invention being equally useful for securely fastening the
sashes when closed entirely.
To effect this, construct a fasten of a simple nature as shown on Fig. 2 and
marked C, D, E. C is a bar of brass, iron, wrought rolled, cast malleable or other
metal or composition, and is of any suitable thickness, width or length preferably
about 5" long " wide and 3" thick this bar has several holes or slots, about one inch
apart as shewn on the front elevation Fig. 3, the double rings or circles on this
elevation being for screws to secure the bar to the upright of sash A Fig. 2—the
other holes being to receive the bolt E on Fig. 2 which may either be threaded as
shown with a Whitworth" or other thread, or wholly plain and may also be in
section of any convenient form, the head of the bolt may be of the description of
a knob, thumbpiece, cross, T or butterfly wing or other form and may be moulded
cast or formed with the bolt or be altogether separate. The bar C can either be
secured to the upright of the upper sash as shown on Fig. 1 and again on C-A
sash-in
Fig. 2 or a pair of bars can be used and fixed on the stiles of the upper
all cases the face of the bars to be flush with face of the stiles or uprights.
D Fig. 2 is a guide or bracket to receive the bolt E and may be in section of this
or other suitable form, the holes through which the bolt passes being either tapped
or plain as considered most advantageous this bracket or guide is secured to the
meeting rod of the lower sash see Fig. 2. E Fig. 2 is the bolt with a Whitworth
or other thread or may be left entirely plain, the inventor considers the threaded
bolt preferable, as when the sashes are entirely closed, the bolt E screwing into the
bar C as shown on Fig. 2 pulls the two meeting rails hard against the parting beads
of the sash frame, thus keeping the sashes firm, and preventing the rattling noise
occasioned generally by high winds.
Fig. 1 of the accompanying drawings represents a sash frame and sashes, the
latter being partially open, and secured by my invention in this fig. F is the sash

COMPLETE SPECIFICATION.
Improvements in the Methol of Securing Window Sashes when
Closed or Partially Closed and in Appliances used in connection
therewith.
I, JOHN HENRY LYON, Gas Works Lessee & Manager, of The Retreat, Cosham,
Ilants, 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 :-
To facilitate the description of my invention reference will be necessary to the
drawings accompanying my Provisional Specification, as also to the drawings
necompanying this Specification.
The invention has for its object, more particularly, the fastening of window sashes,
when it is desired to leave them partially open for ventilation of the room or rooms
at the same time the invention being equally useful for securely fastening the sashes
when entirely closed. To effect this 1 construct a fasten of a simple nature as
shewn on Fig. 2 anel marker ('D) ½ on drawings accompanying my Provisional
Specification, and as shown in a modified and improved form on drawings necom-
panying this Specification by Figs. 1, 2, 3, & 4.
Fig. 1 on drawing accompanying this Specification, represents the centre upright
bar of a window sash, and has part of my invention shown upon it and marked C-
and this upright is assumed to be an upright bar of the top or upper sash, and C is
a bar of metal with several holes drilled through it in the position or other con-
venient position and marked by the broken lines, these holes may be round square
or other form and may be left plain to receive a bolt or may be tapped to receive a
threaded screw B-B are the top and bottom bars of the upper and lower sash, the
second part of my invention being shewn secured to the top bar of the lower sash
and is marked D and is prepared to receive a bolt or screw; in the present instance
it is shown as having a threaded screw E. The part marked D I call a bracket and
may be of this or other convenient form or shape. Figs. 5 & 6 are plan and
elevation of a bar for the upper sashes of windows when there are no upright centre
bars, and the same may be of the form shewn or other convenient shape, and may
if found more convenient be hinged.
it
Fig. 2 represents my apparatus attached to a sash partially open, the bracket D
being secured to the top bar of the bottom sash which is marked B' and the bar C
being secured to the upright bar A of the top sash and F is the distance the top of
the bottom bar B of the upper sash, is from the bottom of the top bar I of the
lower sash, in this position the sashes would be open about an inch.
To be brief my invention consists of a fastener more especially for securing
window sashes when open a sufficient distance for the purposes of ventilation, and
equally useful for securing the same when closed and the fastener consists of three
pieces riz. a bar of metal or metallic composition of the following or other
dimensions 4″ × ×4″ and which is marked Con Fig. 1. Secondly a bracket of
metal or metallic composition and which is marked on Fig. 1-D. And thirdly a bolt
or screw with knob, thumbs piere or other form of head and which is marked E
Fig. 1.
All the parts of the fastener can be made of any suitable metal and may
be in section of any form.
Fig. 3 is an end view of a suitable bracket and represents the bracket marked D
on Fig. it is not imperative that the same be of this section, as it can be made of
Any section or form

page_text: Fig. 4 is the front view of Fig. 3 but may be made that this view shall be plain
ornamental or otherwise.
The method of applying my fastener to window sashes is as follows viz. to let in the
bar Cas shewn in Fig. 1 to the upright bar A and secure it by two or more screws.
Bracket D is secured by screws to the top bar of the lower sash and the bolt E is
then applied and when thus secured the sashes may be opened and secured in any
of the holes in the bar C or if not required open may be secured closed as shewn
in Fig. 1.
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. That my invention is simple and effective.
2nd. It offers more resistance to burglars than other fasteners.
3rd. It admits of window sashes being left open for ventilation and enables the
sashes to be perfectly secured (whilst open for such purposes) from outside
intrusion.
