Improvements in Fastenings for Windows and the like.
1 FREDERIC SMITH, of 62 Market Street, Manchester, Architect, do hereby
declare the nature of this invention to be as follows:-
The improvements relate to fastenings for windows and the like, and have for
object greater security and convenience than at present obtains.
To accomplish this and to effect my improvements, I attach to any convenient
part of the window sash, a bracket, of metal or other suitable material, to which is
fulcrumed a screw-threaded arm, provided with a winged or other nut, and capable
of being moved upon its fulcrum in one plaue and with a movement limited in
extent by a suitably shaped foot, or by stops or other means, so as to keep clear of
the glass.
I also provide, for attachment to the immovable portion of the window framework,
a second bracket, slotted or forked at one extremity, and so placed that when the
fulcrumed arm beforementioned is moved to a position perpendicular or thereabouts
to the window, such arm passes within the slot of the forked bracket, and is secured
to the latter by means of the winged or other nut. In similar manner, the apparatus
may be arranged as a simple sash fastener by attaching one portion to the upper
and the other portion to the lower sash frames as will be readily understood.
To prevent the fulcrumed arm from being forced out of this slot after the nut is
tightened, 1 form upon each of the prongs of the forked bracket a projection or
stop, against which the nut may be caused to abut.
To unfasten the window, the nut is unscrewed, and the fulcrumed arm is swivelled
out of the slot and carried to the other extremity of its movement, which is, by
preference, at such an angle as to enable the head of the nut to be clear of the
glass of the window.
If desired, I may provide a spring or springs, or other means for automatically
forcing the fulcrumed arm open, to unfasten the catch, on the loosening of the nut,
or for merely holding such fulcrummed arm in a particular position; likewise more
than one arm may be fulcrumed upon the sash bracket, and more than one slot or
fork formed in or on the frame bracket, to correspond; and other variations in
detail may be made, such as the design, size and material of the various parts, and
the method of attaching the brackets in their respective positions, without departing
from the peculiar character of the invention.

page_text: I, FREDERIC SMÍTн, of 62 Market Street, Manchester, Architect, 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 improvements relate to fastenings for windows and the like, and have for
object greater security and convenience than at present obtains.
To accomplish this and to effect my improvements, I attach to any convenient
part of the window sash, a bracket, of metal or other suitable material, to which is
fulcrumed a screw threaded arm, provided with a winged or other nut, and capable
of being moved upon its fulcrum in one plane, and with a movement limited in
extent by a suitably shaped foot, or by stops or other means, so as to keep clear of
the glass:
I also provide, for attachment to the immovable portion of the window framework,
a second bracket, slotted or forked at one extremity, and so placed that when the
fulcrumed arm before-mentioned is moved to a position perpendicular, or thereabouts,
to the window, such arm passes within the slot of the forked bracket, and is secured
to the latter by means of the winged or other nut. In similar manner, the apparatus
may be arranged as a simple sash fastener, by attaching one portion to the upper
and the other portion to the lower sash frames, as will be readily understood.
To prevent the fulcrumed arm from being forced out of this slot after the nut is
tightened, I form upon each of the prongs of the forked bracket a projection or
stop, against which the nut may be caused to abut.
To unfasten the window, the nut is unscrewed, and the fulcrumed arm is swivelled.
out of the slot, and carried to the other extremity of its movement, which is by
preference at such an angle as to enable the head of the nut to be clear of the
glass of the window.
If desired, I may provide a spring or springs, or other means, for automatically
forcing the fulcrumed arm open, to unfasten the catch, on the loosening of the nut,
or for merely holding such fulerumed arm in a particular position ; likewise more
than one arm may be fulcrumed upon the sash bracket, and more than one slot or
fork formed in or on the frame bracket, to correspond.
But that the improvements may be better understood I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me:
DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional plan of. a portion of a window frame and sash fitted at the
side thereof. with one form of my improved fastening, and Fig. 2 is a side elevation
of the same.
Fig. 3 is a view of the fastening at right angles to Fig. 1.
Figs. 4 & 5 are cross sections of portions of window sashes when the windows
are closed, to which are fitted other and suitable forms of my improved fastening.
The same letters indicate corresponding parts wherever they occur.
a is the metal or other bracket to which is fulcrumed the screw-threaded arm b,
provided with a winced another nut
the coound or separate bracket

page_text: arm b, provided with a suitably shaped foot b', is turned on the pin or fulcrum.
at 62 into the slotted or forked end of the bracket d, and the winged nut c is then
turned round until it abuts against the arms of such bracket, the screw threaded
arm b being prevented by the projections d' froin coming out of the slotted or
forked end of the bracket d.
When the window requires to be opened, the winged nut c is unscrewed until it
will pass the projections d' and allow the arm 6 to be turned on its fulcrum out of
the slotted or forked end of the bracket before uamed; disconnection between the
window, frame and sash being thereby effected the window may be raised or
lowered as the case may be, carrying with it the whole of the improved fastening
excepting the bracket d on the window frame e. The arm 6 is preferably so.
formed at bas to be incapable of coming in contact with the window glass k.
In Figs. 4 and 5 the bracket a carrying the arm & and nut c is attached to the
lower portion of a window sash, and the bracket d is attached to the upper portion
of the corresponding window sash, two modes of attachment being shown; but in
order to automatically release the arm 6 from the slotted bracket when the nut c is.
unscrewed, or in order to prevent the arm b from falling with its own weight when
once released, I cause a spring or springs h to abut against a suitably shaped
portion of the arm b, and preferably at that end nearest the fulcrum or point of
turn 62.
The arm is shown provided with an excrescence at its extremity for preventing-
the removal of the nut c.
Variations in detail may be made, such as the design, size, and material of the
various parts, and the method of attaching the brackets in their respective.
positions, without departing from the peculiar character of the invention.
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 :-
In fastenings for windows and the .like, the combination of a bracket or block a
on which is fulcrumed a screw threaded arm b carrying a nut c, such arm engaging
with or entering into a slotted bracket d provided with a projection or projections d¹,
and with or without the spring h, all arranged for the purpose and in manner-
substantially as herein shown and described.
