Improvements in Holders and Fasteners for Sliding Window
Sashes.
We, WILLIAM JOHN TRERY GOATLEY, of 2 Tufton Street, Westminster, in the
County of Middlesex, Engineer, and GEORGE BURTON, of 58 St. Paul's Church
Yard, in the City of London, Engineer, do hereby declare the nature of our
invention for IMPROVEMENTS IN HOLDERS AND FASTENERS FOR SLIDING WINDOW
SASHES to be as follows:-
:―
Our invention relates to holders and fasteners for retaining the sliding sashes of
carriage and other windows in any desired position. The fasteners may be applied to
the sash or to the frame in which the sash is made to slide; and they may be entirely
concealed from view, or placed upon the face of the sash or fraine.
In the case of the concealed method of fastening, a short bolt, preferably
cylindrically shaped bolt, rounded at the outer end, is arranged to slide in and out of
a sleeve or box, with a spiral spring adapted to press the bolt outwards. This is let
into the thickness of the sash or frame, (as the case may be) the-rounded end of the
bolt being pressed outward against the frame or the sash according to the plan adopted.
This pressure is sufficient to hold the sash in any position in which it may be placed,
relative to the frame. To assist the pressure of the bolt in holding the sliding sash,
the surface against which the rounded bolt end presses is made of a waved section
along the line of travel of the sash, or slightly cup shaped indentations are used as
an equivalent thereof; the object being to produce a sufficient amount of frictional
contact surface-assisted by the pressure of the spring-to hold the sash against the
force of gravity, and yet allow of the sash being lifted or lowered against the aforesaid
frictional pressure. To avoid undue leakage of air through the waved corrugations
already described, the width of the same is made less than the thickness of the sash,
and the corrugations or indentations, (made upon a metal plate or otherwise) are sunk
below the sliding surface upon which it is placed, so that plain surfaces are opposed
to plain surfaces on the inner or outer surfaces of the window, or both.
The visible fastening is conveniently placed on the interior face of the sash (for
example) and it consists of an actuating knob or handle working in a suitable bearing.
Secured to the axis of the handle, or forming a solid part thereof, is a disc, or one or
two crank arms, as the equivalent thereof, which are intended to work one or two (as
the case may be) horizontally placed rods or bolts to and from the frame. Corre-
sponding notches, orifices, or indentations are made in the frame to receive the said
bolt end or ends. In this plan the end of the bolt next to the frame is bevelled, or it
may be rounded as in the first instance; and is adapted to be pressed against the
frame or into an indentation or notch by the force of a spring, as before.
If the sash is heavy, or for greater security, two bolts may be used, operating
oppositely against the sides of the frame. These can be worked from two crank arms.
or pins in the disc; the actuating handle which controls the same may be fashioned
for use as a sash lift also. When this kind of fastening is placed on the frame instead
of on the sash, the bolt may be concealed within the frame and caused to act upon
the edge of the sash, while the handle only is visible; and this plan may be corre-
spondingly followed when placed on the sash, when the latter is thick enough for
the purpose.
Suitable guides or sleeves may be used for the bolts in any of the
cases named, but where cheapness is an object, a hole or holes sunk in the wood
may serve for the sleeve or box, instead of using a special metal box. The bolt or
bolts used may be flattened or shaped to suit the thickness of the sash or space
occupied.
In private and railway carriage windows, which are usually lifted and lowered

page_text: by means of a strap, a considerable amount of play is required in the frame to
accommodate the varying angles occupied by the sash. Space is further required
to accommodate the strap, and this space frequently becomes charged with dust,
and is otherwise objectionable. By our system of fastening the aforesaid windows,
and others of like character, a better fitting sash may be made and greater neatness
effected; while a reduction may be made in the thickness of the carriage door
or frame, and more space obtained.

Improvements in Holders and Fasteners for Sliding Window
Sashes.
We WILLIAM JOHN TRERY GOATLEY of 36 Upper Baker Street Regents Park,
in the County of Middlesex Engineer (formerly of 2 Tufton Street Westminster),
and GEORGE BURTON, of 58 St. Pauls Church Yard, in the City of London, Engineer,
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 relates to holders and fasteners for retaining the sliding sashes of
Carriage and other windows in any desired position. The fasteners may be applied
to the sash, or to the frame in which the sash is made to slide, and they may be
entirely concealed from view.
There is appended hereto a sheet of drawings to which reference is hereinafter
made and in which Figure 1 represents the sectional elevation and Figure 2 the
sectional plan of a window, or other similar frame to which our Invention is
applied. In each of the Figures similar elements, and details are indicated by
similar letters.
A short bolt A, preferably cylindrically shaped bolt, rounded at the outer end,
is arranged to slide in, and out of a sleove or box a with a spiral spring b adapted
to press the bolt outwards. This is let into the thickness of the sash, or frame c
(as the case may be) the rounded end of the bolt being pressed outward against
the frame c, or tho saslı E, according to the plan adopted. This pressure is sufficient
to hold the sash in any position in which it may be placed relative to the frame.
To assist the pressure of the bolt in holding the sliding sash, the surface B against
which the rounded bolt end presses is made of a waved section along the line of
travel of the sash, or slightly cup-shaped indentations, or hollowed spaces, are used,
as an equivalent thereof, the object being to produce a sufficient amount of frictional
contact surface-assisted by the pressure of the spring-to hold the sash against
the force of gravity, & yet allow of the sash being lifted, or lowered against the
aforesaid frictional pressure. To avoid undue leakage of air through the waved
corrugations already described, the width of the same B is made less than the
thickness of the sash, & the corrugations, or indentations, or hollowed spaces (made
in, or upon, a metal plate, or otherwise) are sunk below the sliding surface upon
which it is placed, so that plain surfaces are opposed to plain surfaces, on the inner,
or outer surfaces of the window sash, or both.
If the sash is heavy, or for greater security two, or more, bolts may be used,
operating upon opposite sides of the window, or sash, and where cheapness is an
object, a hole or holes sunk in the wood may serve for the sleeve or box instead
of using a special metal box, and the spring be placed therein, at the back of the
bolt, or otherwise. The bolt, or bolts used may be flattened, or shaped to suit the
thickness of the sash, or space occupied.
The portion F need not necessarily he of glass, but may be of wood, or other
material, as used in "Pay," "Enquiry," or other similar windows.

page_text: Having now particularly described, and ascertained the nature of our said Inven-
tion and in what manner the same is performed we declare that what we
claim is :-
In a window holder, fastener, or catch, the combination of a spring bolt, working
with, in conjunction with, or against, a waved, corrugated, or indented plate, or surface
of metal, or otherwise, the whole being operated as herein before described, and
illustrated by the accompanying drawings.
