page_text: LETTERS PATENT to Alfred Sutherland Nixon, of Kettering, in the County of
Northampton, for an Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF GREEN-HOUSES, SKY-LIGHTS, ROOFS, AND OTHER LIKE STRUCTURES."
PROVISIONAL SPECIFICATION left by the said Alfred Sutherland Nixon
at the Office of the Commissioners of Patents on the 8th April 1880.
ALFRED SUTHERLAND NIXON, of Kettering, in the County of Northampton.
"IMPROVEMENTS IN THE CONSTRUCTION OF GREEN-HOUSES, SKY-LIGHTS, ROOFS,
AND OTHER LIKE STRUCTURES."
My Invention is designed to facilitate and cheapen the construction of green-
houses, sky-lights, roofs, and other like structures, dispensing with the use of putty,
metal, and the like for holding the panes or squares of glass, slate, or other
material in the sash bars. To this end I construct the sash bars with grooves or
recesses in opposite sides or parts. These sash bars are designed to be arranged
horizontally, and with the one grooved side higher than the other, and I will for
clearness distinguish the grooves as the upper and lower grooves respectively. The
upper groove is to receive the lower edges of the panes or squares of glass, slate, or
the like, and is made shallower than the lower groove, which is designed to receive
the upper or higher edges of the said panes or squares. One side (I will call it the
inner side) of the upper groove is inclined or bevilled towards the bottom of the
groove, so as to direct the glass or slate towards and against the other or outer side
or wall of the groove, which is of a rounded form of less height or depth than the
inner side, and cut away at intervals so that water may run off, to facilitate which
the outer side of the sash bar is or may be bevilled. The sash bars, constructed as
described, are arranged parallel to each other and at a suitable distance apart to
allow of the panes or squares of glass, slate, or other material being inserted, as
follows, that is to say, the upper or higher edge of the pane or square is inserted
in the lower groove of one bar, then the lower part of the pane or square is placed
against the higher portion of the bevilled side of the upper groove of the next
lower bar, and finally, the lower edge of the pane or square is allowed to descend
to the bottom of this groove. Thus the pane or square is held in place by the two
bars without putty, metallic clips, or other such means of fastening, and it will be
understood the form of the upper groove in the bar is such as to securely hold the
lower edges of the panes or squares.
The form of the sash bar in cross section may obviously be more or less modified
without departure from the essential characteristics of my Invention.

"IMPROVEMENTS IN THE CONSTRUCTION OF GREEN-HOUSES, SKY-LIGHTS, ROOFS,
AND OTHER LIKE STRUCTURES."
My Invention is designed to facilitato and cheapen the construction of green-
houses, skylights, roofs, and other like structures,-dispensing with the use of putty,
metal, and the like for holding the squares or panes of glass, slate, or other material
in the sash bars. I construct the sash bars with grooves or recesses in opposite
sides or parts. These sash bars are designed to be arranged horizontally, and with
the one grooved side higher than the other, and I will for clearness distinguish the
grooves as the upper and lower grooves respectively. The upper groove is to
receive the lower edges of the panes or squares of glass, slate, or the like, and is
made shallower than the lower groove, which is designed to receive the upper or
higher edges of the said panes or squares. One side (I will call it the inner side)
of the upper groove is inclined or bevilled towards the bottom of the groove, so as
to direct the glass or slate towards and against the other or outer side or wall of
the groove which is of a rounded form, and of less height or depth than the inner
side, and cut away at intervals 50 that water-may-run-off,-to-facilitate which, the
outer side of the sash bar is or may be bevilled. The sash bars, constructed as
described, are arranged parallel to each other and at a suitable distance apart to
allow of the panes or squares of glass, slate, or other material being inserted as
follows, that is to say, the upper or higher edge of the pane or square is inserted in
the lower groove of one bar, then the lower part of the panc or square is placed
against the higher portion of the bevilled side of the upper groove of the next
lower bar, and finally, the lower edge of the pane or square is allowed to descend
to the bottom of this groove. Thus the pane or square is held in place by the two
bars without putty, metallic clips, or other such incans of fastening, and it will be
understood the form of the upper groove in the bar is such as to securely hold the
lower edges of the panes or squares.
The form of the sash bar in cross-section may obviously be more or loss modified
without departure from the essential characteristics of the Invention.
Referring to the accompanying Sheet of Drawings:-
Fig. 1 is a perspective view of part of a sash bar according to my Invention, and
which may be made of wood or metal.
Fig. 2 is a front view (smaller) of part of a sash bar with panes or squares of
glass or other material inserted in the upper and lower grooves.
Fig. 3 shews in cross-section one of the bars with panes or squares in the upper
and lower grooves, and
:
Fig. 4 represents part of a roof when finished; A being the top, A¹ the middle,
and A the bottom horizontal bars; B, B, rafters, C, C, glass or slate, and D an
ordinary ridge.
:
Referring now to Figs. 1, 2, and 3, a is the sash bar with grooves or recesses in
opposite sides or parts; the upper groove b is to receive the lower edges of the
panes or squares of glass or other material; the lower groove c is to receive the
upper or higher edges of the said panes or squares. The inner side b¹ of the
groove b is inclined or bevilled towards b², as shewn, so as to direct the pane or
square towards the other or outer side or wall 6s of the groove, which is of a
rounded form, as shewn clearly in Fig. 3, and is cut away at intervals, thus leaving
spaces a¹ for water to run off to facilitate which also the bar is bevilled at aº.
Figs. 5 and 6 show a modified arrangement in which the parts a³ are made

page_text: separate and secured to the part a which is formed with the lower groove at c, the
upper groove being at b, b, b, between the parts a and a².
Having described the nature of my said Invention, and explained the manner of
carrying it into practical effect, I would have it understood that what I consider to
be novel and original, and thereforo claim as the Invention secured to me under
the Letters Patent hereinbefore in part recited is, the constructing green-houses,
sky-lights, roofs, and other like structures, substantially as hereinbefore described
with reference to the accompanying Drawings, and particularly the improved sash
with upper and lower grooves arranged to receive the upper and lower edges of the
panes or squares of glass, slate, or the like, and to hold the same, as above
explained.
In witness whereof, I, the said Alfred Sutherland Nixon, have hereunto set
my hand and seal, this Sixth day of October, in the year of our Lord One
thousand-eight-hundred-and eighty..
