page_text: LETTERS 'PATENT to John Edward Walsh, Mechanical Draughtsman and.
Engineer, of Halifax, in the County of York, for the Invention of "IMPROVE
MENTS IN HOLDERS AND FASTENERS FOR WINDOWS AND SASHES,"
Sealed the 25th April 1879. and dated the 30th October 1878.
PROVISIONAL SPECIFICATION left by the said John Edward Walsh at the
Office of the Commissioners of Patents on the 30th October 1878.
JOHN EDWARD WALSH, Mechanical Draughtsınan and Engineer, of Halifax, in
the County of York. "IMPROVEMENTS IN HOLDERS AND FASTENERS FOR WINDOWS
AND SASHES."
My Invention relates,-
Firstly. To an improved fastener for sliding windows, by means of which the
windows are self fastening.
1
Secondly. To improved holder and fastener for windows which swing on centres
opening inwards and outwards.
Thirdly. To improved holders and fasteners for the windows of railway and
other carriages.
1. I construct the first part of my Invention as follows:-
On the lower or front sash I fix a plate (a portion of which projects over the
upper or outer sash); attached to the plate is a fulcrum lever, one of which (the
releasing end) formers a thumb-piece and projects inwards from the sashes, the other
end projecting outwards over the upper or outer sash (forms the fastening or locking
part); a blade or spriral spring fixed to the plate acts against the fastening end of
the lever and keeps it in position. On the upper or outer sash I fix another plate
having a projection, which forms a neck or slot for the locking part of the lever,
which is kept in position by the spring, the upper side of the projection forms an
incline; or two levers may be employed on one fulcrum, having a spring between
their releasing or thumb-piece ends, which presses together or closes their opposite
ends, the projection on the upper sash plate (in this case) having a neck and button

having semicircular holes (the under side of which holes are inclined) corresponding
in size to the neck of. the projection, thus when the thumb-pieces are pressed
together the opposite ends which are encircling the neck are opened or released, and
either of the windows may be opened; in shutting the windows the button or
inclined projection presses against or between the lever or levers, and opening
them depresses the spring until the lever or levers is or are past the incline; the
spring then pushes them or it into the slot or neck; thus in case the window is self
fastening, the projecting plate on the lower sash prevents the window from being
unfastened from outside.
2. The second part of my Invention relating to swing windows I construct as
follows:-
In the side or edge of one end of the window frame I fix at a convenient
distance from its centres a fulcrum catch and spring; to, the side of the casement
or opening I fix a shallow toothed rack or plate with dents thereon, the rack or
plate projects outwards at a radius from the centres, and for windows a distance
from the ground a cord is attached to the catch of the sash, so that when pulled
from below the catch and spring are depressed or withdrawn from the rack, and
the window can be opened, and when the cord is slackened the catch enters a notch
in the rack and holds the window open in whatever position it may be; to close it
the catch cord is again pulled, so as to release or withdraw the catch from the
notch; and a cord attached to the opposite end of the window, pulled at the same
time, shuts the window, the catch entering the first notch or tooth in the rack,
which is deeper and formed to hold both ways, firmly secures and fastens the
window.
3. The third part of my Invention relating to fasteners or holders for the
windows of railway and other carriages I construct as follows:-To the centre of
the upper frame of the window I fix a handle or lifting piece, which when taken
hold of for the purpose of raising the window moves or slides slightly upwards; to
this is attached a cord, chain, or wire; in the top part of the side edge of the frame
I fix a catch on pivot and a spring, and in the side of the window slide a rack or
dented plate; the cord, chain, or wire is connected to the catch, and on the
window being lifted the lifting piece, to which the other end of the cord is attached,
is moved upwards, pulling or moving the cord, and so releasing the catch from the
rack; and on leaving hold of the lifting piece the catch will enter the notch or rack,
and the window fastened at any height or position, and the straps or pins as used
heretofore for this purpose are dispensed with. Or instead of the chain or cord a
spring fulcrum lever or a heavy-ended lever may be used, having a catch end; or
two lifting pieces may be employed, one near each end of the upper window frame,
one only of the lifting pieces sliding, and so depressing the catch or lever. Or the
lifting piece may be fixed to a catch, the former sliding in an oblique slot, so that
when slid up the slot the catch recedes or withdraws from the rack or dents, and
as soon as the lifting piece is released the catch again engages with the rack, either
by means of a spring or by its own weight.

28th April 1879.
John Edward WALSH, of Halifax, in the County of York, Mechanical Engineer
and Draughtsman. "IMPROVEMENTS IN HOLDERS AND FASTENERS FOR WINDOWS
AND SASHES."
My Invention relates,―
Firstly. To an improved fastener for sliding windows, by means of which the
windows are self fastening.
Secondly. To improved fasteners and holders for the windows of railway and'
other carriages.
I construct the first part of my Invention as follows :-
On the lower or front sash I fix a plate (a portion of which projects over the
upper or outer sash); attached to the plate is a fulcrum lever, one end of which (the
releasing end) forms a thumb-piece, handle, or knob, and projects inwards from the
sashes, the other end projecting outwards over the upper or outer sash forms the
fastening or locking part; a blade, spiral, or other spring fixed to the plate acts
against the fastening end of the lever and keeps it in position.
On the upper or outer sash I fix another plate having a projection, which forms
a neck or slot for the locking part of the lever and is kept in position by the spring,
the upper and outer sides of the projection forms the incline; the fastening end of
the lever having a semicircular projection or lip, which bearing against the outer
incline, draws the two sashes together, and preventing their shaking.
By moving the end of the lever the locking part is moved clear of the catch, and
either of the windows may be opened; in shutting the windows the upper incline
of the projection presses against the lever and depresses the spring until the lever
is past the incline, the spring then pushes the locking part of the lever into the slot
or neck, thus the window is self fastening. The projecting plate on the lower sash
prevents the window from being unfastened from outside. Or in lieu of the pro-
jecting plate a stop lever may be used.
The second part of my Invention relating to fasteners or holders for the windows
of railway and other carriages I construct as follows:-In the centre of the upper
frame of the window I fix a handle or lifting piece attached to a fulcrum lever
having a catch end, which when taken hold of for the purpose of raising the
window moves or slides slightly upwards.
In the side of the window slide a rack or dented plate is fixed; on the window
being lifted the lifting piece to which the lever is attached is moved upwards (on
its fulcrum), the catch end moving or receding from the rack, so releasing itself; the
lever is made beavy-ended, or a spring is attached to it, so that on leaving hold of
the lifting piece the catch will enter the notch or rack, and the window is secured at
any height or position; in lowering the window hold is retained on the lifting
piece. The straps and pins as used heretofore for this purpose are dispensed with.
Such being the nature and object of this my said Invention, in order that the
same may be fully understood I have hereunto annexed two Sheets of Drawings
illustrative thereof, and have marked the same with figures and letters of
reference.

page_text: forms a thumb-piece, handle, or knob, and projects inwards from the sashes, the
other end projecting outwards over the upper or outer sash B forms the fastening
or locking parts F and F"; a blade; spiral, or other spring G fixed to the plate
acts against the fastening end of the lever D and keeps it in position.
On the upper or outer sash I fix another plate H having a projection J, which
forms a neck or slot for the locking part F of the lever D, and is kept in position
by the spring G, the upper and outer sides of the projection J forms the inclines
K and K¹, the fastening end of the lever having a semicircular projection or lip F¹,
which bearing against the outer incline K draws the two sashes together and
prevents their shaking.
By moving the end L of the lever D the locking part F is moved clear of the
catch J, and either of the windows may be opened; in shutting the windows the
upper incline K¹ of the projection J presses against the lever D and depresses the
spring G until the lever is past the incline, the spring then pushes the locking
part F of the lever D into the slot or neck, thus the window is self fastening.
The projecting portion M of the plate C on the lower sash A prevents the
window from being unfastened from outside. The spring G is shown in various
forms in steel and india-rubber.
Or in lieu of the projecting plate M a stop lever N may be used, as at Fig. 9;
when necessary a holding-back catch N¹ may be used, as at Figs. 6 and 7, or a
spring X, as at Figs. 1 and 2.
Sheet 2, Figs. 10 and 11, illustrate a fastener for carriage windows. P is a
handle or lifting piece attached to a fulcrum lever O (having a catch end R), which
lifting piece when taken hold of for the purpose of raising the window moves or
slides slightly upwards. In the side of the window slide a rack or dented plate is
fixed; on the window being lifted the lifting pieco P to which the lever O is
attached is moved upwards in the slot X on its fulcrum T, the catch end R moving
or receding from the ruck S so releasing itself; the lever O is made heavy-ended or
a spring is attached to it, so that on leaving hold of the lifting piece P the catch
will enter the notch or rack S, and the window is secured at any height or position;
in lowering the window, hold is retained on the lifting piece. By the above method
the straps and pins as used heretofore for this purpose are dispensed with.
Having thus fully described the nature and particulars of this my said Invention
I would have it understood that I claim,―
Firstly. The combination of fulcrum lever D, inclined catch J, and inclined lip F¹,
as and for purposes described and illustrated.
Secondly. The combination of the lifting piece P, fulcrum lever O, and rack S,
acting in the manner and for the purpose substantially as described.
In witness whereof, I, the said John Edward Walsh, have hereunto set my
hand and seal, this Twenty-fifth day of April, in the year One thousand
eight hundred and seventy-nine.
