I'ROVISIONAL SPECIFICATION.
Improved Method of Glazing Sashes, Skylights, Roofs, and the like.
⚫ GEORGE MARTIN 61 Brook Street Smethwick in the County of Stafford do
hereby declare the nature of this invention to be as follows:-
:-
This invention consists in the providing of a slotted sash bar and studded capping
in combination with sheets of glass for the purpose of glazing roofs and other
surfaces.
In carrying out my invention I provide a T shaped sash bar of any usual and
convenient dimensions.
At suitable distances on the web of such sash bar I provide radial locking slots,
such radial locking slots being pierced through the web in such a manner as to form
openings leading from the upper edge of the web to any desired distance through
the vertical face of such web.
At one or both ends of sash bar I pierce a stopping slot and in conjunction there-
with I pierce through the horizontal base of the web, two stopper holes, one on
each side of the web.
I next provide a sash bar cover which consists of a sheet or piece of metal, bent,
drawn, or otherwise produced so that its transverse section present to view a hollow
frame, the central portion of which corresponds in internal dimensions to the
vertical web of sash bar, the right and left hand lower portion of cover are formed
into gutters, the upper edge of such gutters being turned over to form bearings to
receive the sheets of glass, the sheet metal being further turned over forming a
supporting bracket under the gutter and again turned up to form a second gutter,
the upper edge of such second gutter constituting the terminal edge or end of the
bent metal.
It will thus be readily understood that the sash bar cover is formed with two
gutters on the right hand side and two gutters on the left hand side.
The sash bar cover is provided with locking slots corresponding with the locking
slots provided on the upper part of sash bar web.
In forming the locking slots in the sash bar and sash bar cover I prefer in some
cases to place the cover over the sash bar and then, by means of suitable press tools,
dies or punches, pierce out the locking slots from the sash bar cover and from the
sash bar, at one operation.
I next provide a locking cap which consists of a piece of sheet metal bent in such
a manner that its transverse section will pass easily over the sash bar cover, the
lower right and left hand edges of such transverse section terminating at any
suitable distance from the centre of such transverse section by preference these
lower right and left hand edges would constitute the terminal points of a concave
configuration curving upwards so that such transverse section would closely
resemble the capital letter A, the cross bar representing the locking bars that are
situated within the cap, such bars consisting of short pieces of cylindrical metal
either solid or tubular.

page_text: The number of locking bars provided within the cap would correspond with the
number of locking slots provided in the sash bar and sash bar cover.
Inext provide a moveable stop which consists of a piece of metal formed in a
U shape.
I next provide sheets of glass of any suitable and convenient size.
In putting together the various parts of my invention and in glazing a skylight,
a window sash or other surface I proceed to utilize the parts constituting my
invention in the following manner :-
I fix my slotted sash bars to the usual supports or framework provided to receive
such sash bars.
The pane of glass is lowered with one edge resting on the upper edge of the
gutter formed at the bottom of the sash bar cover.
The sash bars and sash bar covers would be fixed at such distances apart that
the back edge of the pane of glass would rest on the upper edge of the second sash
bar covor.
To lock or secure the pane of glass on its two gutter edge bearings 1 lower the
locking cap over the sash bar and sash bar cover and introduce the locking bars,
provided inside the cap, into the slots formed in the upper edge of sash bar web
and then by exerting end pressure against the locking cap move the locking bars
latterly along the locking slots and thus bring the lower edges of the looking cap
to hear continuously on the upper surface of the pane of glass.
In order to prevent the locking cap from moving backwards out of the locking
slots lower the U shaped moveable stop over the end of sash bar, the circular top
em of the stop passing into the slot provided to receive it, the two circular fork
ends passing through the two circular holes provided to receive them, such circular
ends may be further secured by means of transverse linch holes and linch pins or
by means of screwed nuts or other equivalents.
The panes of glass fixed in the manner hereinbefore described would be held and
secured rigidly between the upper edge of the gutter, formed at the bottom of sash
Iar cover, and the lower edge of locking cap as hereinbefore fully set forth.
Dated this 3rd day of May, 1890.

COMPLETE SPECIFICATION (AMENDED).
Improved Method of Glazing Sashes, Skylights, Roofs, and the like.
GEORGE MARTIN 61 Brook Street Smethwick in the County of Stafford,
Glazier 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:—
This invention consists in the providing of a slotted sash bar and stulded capping
in combination with sheets of glass for the purpose of glazing roofs and other
surfaces.
In carrying out my invention I provide a T shaped sash-bar of any usual and
convenient dimensions.
At suitable distances on the web of such sash bar I provide radial locking slots,
such radial locking slots being pierced through the web in such a manner as to
form openings leading from the upper edge of the web to any desired distance
through the vertical face of such web.
At one or both ends of sash bar 1 pierce a stopping slot and in conjunction there-
with pierce through the horizontal base of the web, two stopper holes, one on
onch side of the web.
1 next provide a sash bar cover which consists of a sheet or piece of metal, bont,

page_text: drawn, or otherwise produced so that its transverse section present to view a hollow
frame, the central portion of which corresponds in internal dimensions to the
vertical web of sash bar, the right and left hand lower portion of cover are formed
into gutters, the upper edge of such gutters being turned over to form bearings to
receive the sheets of glass, the sheet metal being further turned over forming a
supporting bracket under the gutter and again turned up to form a second gutter,
the upper edge of such second gutter constituting the terminal edge or end of the
bent metal.
It will thus he readily understood that the sash bar cover is formed with two
gutters on the right hand side and two gutters on the left hand side.
The sash bar cover is provided with locking slots corresponding with the locking
slots provided on the upper part of sash bar web.
In forming the locking slots in the sash bar and sash bar cover I prefer in some
cases to place the cover over the sash bar and then, by means of suitable press
tools, dies, or punches, pierce out the locking slots from the sash bar cover and
from the sash bar, at one operation.
I next provide a locking cap which consists of a piece of sheet metal bent in
such a manner that its transverse section will pass easily over the sash bar cover,
the lower right and left hand edges of such transverse section terminating at any
suitable distance from the centre of such transverse section; by preference these
lower right and left hand edges would constitute the terminal points of a concave
configuration curving upwards so that such transverse section would closely resemble
the capital letter A, the cross bar representing the locking bars that are situated
within the cap, such bars consisting of short pieces of cylindrical metal either solid
or tubular.
The number of locking bars provided within the cap would correspond with the
number of locking slots provided in the sash bar and sash bar cover.
I next provide a moveable stop which consists of a piece of metal formed in
a U shape.
I next provide sheets of glass of any suitable and convenient size.
In putting together the various parts of my invention and in glazing a skylight, a
window sash or other surface I proceed to utilize the parts constituting my invention
in the following manner :-
I fix my slotted sash bars to the usual supports or framework provided to receive
such sash bars.
The pane of glass is lowered with one edge resting on the upper edge of the
gutter formed at the bottom of the sash bar cover.
The sash bars and sash bar covers would be fixed at such distances apart that
the back edge of the pane of glass would rest on the upper edge of the second
sash bar cover.
To lock or secure the pane of glass on its two gutter edge bearings I lower the
locking cap over the sash bar and sash bar cover and introduce the locking bars,
provided inside the cap into the slots formed in the upper edge of sash bar web and
then by exerting end pressure against the locking cap move the locking bars
latterly along the locking slots and thus bring the lower edges of the locking cap
to bear continuously on the upper surface of the pane of glass.
In order to prevent the locking cap from moving backwards out of the locking
slots lower the U shaped moveable stop over the end of sash bar, the circular
top end of the stop passing into the slot provided to receive it, the two circular fork
ends passing through the two circular holes provided to receive them, such circular
ends may be further secured by means of transverse linch holes and linch pins or
by means of screwed nuts or other equivalents.
The panes of glass fixed in the manner herein before described would be held and
secured rigidly between the upper edge of the gutter, formed at the bottom of sash
bar cover, and the lower edge of locking cap as hereinbefore fully set forth.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used.

provide sash bars a of any suitable and convenient length.
I next provide ash bar covers & which consists of a piece of metal bent, drawn
or otherwise formed into the shape shown in transverse section at Figure 6.
In some cases I prefer to place the sash bar cover over the ash bar a and then
by means of suitable tools at one operation pierce or cut out the sluts e from the
sash bar a and also the slots from the cover in other eases I prefer to pierce
the slots at one operation and the slots d by a second operation; in either case the
slots e are formed in the sash bar a to exactly correspond with the slots d formed in
the sash bar cover h.
At one or both ends of the sash bar a (or on any convenient part thereof) I
pierce a stopping slot e, q
1 next provide the locking cap which consists of a piece of sheet metal or other
suitable material bent or otherwise shaped in such a manner that its transverse
sectional form will permit of it being passed easily over the sash bar cover &; within
the cap provide locking bars g.
The lucking bars consist of short
material either solid or tubular.
pieces of cylindrical metal or other suitable
The number of locking bars within the cap would correspond with the
number of locking slots provided in the sash bar and sash bar cover to be locked
by the cap
In putting together the various parts of my invention and in glazing a skylight
or other surface I proceed in the following manner.
I fix my slotted sash bars a to the usual supports or framework provided in a
building to receive sash bars or other equivalents; the pane of glass is lowered
with one side resting on the upper edge j of the gutter formed at the bottom of
sash har cover b.
The sash bars a would be fixed at such a distance apart that the underside of the
back edge of the pane of glass h would rest on the edge of the second sash bar
cover as clearly shewn at Figure 1.
To lock or secure the pane of glass on its two gutter edge bearings jjl lower
the locking cap over the sash bar cover and introduce the locking bars into the
openings & of the slots c, d and then by exerting end pressure against the locking
cap move the locking bars laterally along the locking slots c, d until the
locking bars g rest against the back end m of the locking slots and thus bring the
lower edges of the locking caps to bear continuously on the upper surface of
the pane of glass.
In order to prevent the panes of glass from moving or slipping downwards and
in order to prevent the lacking cap from moving backwards and in order to retain
the locking bolts in their slot bearings I lower a moveable stop o over the end of
each sash bar a the circular top end of the stop o passing into the slot y provided
to receive it, the two circular fork ends r, passing through the two circular
holess, s' provided to receive them.
The ends, may be further secured by means of transverse linch holes and
linch pins or by means of screwed nuts or other equivalents.
What constitutes the essential part of my invention is the providing of slots in

page_text: sash bars and sash bar covers engaging with locking bolts formed on or in a locking
cap irrespective of the shape of the slot and locking bolt and irrespective of the
angle of direction of the said slots.
Having now particually 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. The improvements in the method of glazing as illustrated and described.
2nd. The providing of slots in sash bars and sash bar covers to engage with
locking bolts provided on or in sash bar locking caps for the purpose of gripping or
securing sheets of glass between the upper bearing surfaces of the sash bar covers
and the lower bearing surfaces of the sash bar locking caps as illustrated and
described.
3rd. The utilization of a moveable stop in the manner-illustrated and described in
reference-to-Figures 0 and 10:
