PROVISIONAL SPECIFICATION left by the said William Howitt at the
Office of the Commissioners of Patents on the 9th July 1881.
WILLIAM HOWITT, of Ilford, in the County of Essex, Horticultural Builder.
'AN IMPROVED SASH-BAR FOR THE ROOFS, SIDES, AND ENDS OF HORTICULTURAL
BUILDINGS AND OTHER STRUCTURES FOR WHICH GLASS, SLATE, TILES, LEAD,
ZINC, OR OTHER COVERING IS USED."
My Invention relates to glazing of horticultural and other buildings for which
glass or other roofing is used. I provide a semi-cylindrical piece of any desired
length, preferably of zinc, but copper, iron, lead, or other suitable metal may be
used. It may be cast or formed of bent sheet-metal; it is screwed or otherwise
fastened to the lower edge of a piece of wood, which is placed edge-wise and
longitudinally therein. Over this piece of wood, and fastened to the upper edge
thereof by screws or other convenient attachments, I place two or more pieces of
zinc, lead, copper, or any suitable sheet or cast metal, which form a capping, and
are screwed or otherwise fastened to the upper edge of said piece of wood. The
last of these pieces of sheet or cast metal overlaps that which immediately precedes
it to any desired extent. These pieces when disposed as described are together in
length equal to the length of the first mentioned semi-cylindrical piece of metal.
The overlapping is intended to provide a rest or stop for each square of glass, so as
to hold it in its place. Each square of glass is inserted edgewise between the
pieces forming the capping and the semi-cylindrical piece above described. The
capping is bent or pressed over the edge of each square, and by these means the
glass is held tightly in position, and so as to perfectly exclude water. The interior
of the semi-cylindrical piece above described forms a gutter for carrying off water,
which is discharged over the succeeding square of glass. The squares of glass are
cut in bevilled form for the purpose of carrying off condensed water (but they
may be cut square also). The piece of wood may be prepared or "pickled" so as
to be rendered less liable to decay from the action of water than wood in its
normal condition would be, and the semi-cylindrical piece of sheet or cast metal
may have tar, paint, or other preserving compound poured through it in order to
further preserve the aforesaid piece of wood.

AN IMPROVED SASH-BAR FOR THE ROOFS, SIDES, AND ENDS OF HORTICULTURAL
BUILDINGS AND OTHER STRUCTURES FOR WHICH GLASS, SLATE, TILES, LEAD,
ZINC, OR OTHER COVERING IS USED."
My Invention relates to a sash-bar for glazing and covering purposes, and it
dispenses with the necessity of using putty, cement, or other adhesive substance
for holding the squares of glass or other covering in position.
The Invention is illustrated in the accompanying Drawings, in which Figure 1
is a longitudinal elevation thereof; Figures 2, 3, & 4 are views of the same,
shewing the glass fixed in, & Figure 5 is a view of the side and end of a
complete structure. Like letters indicate the same parts throughout the
Drawings.
I form my improved sash-bar as follows:-I provide a semi-cylindrical piece a,
Figure 1, of any desired length, and preferably of zinc, but it may be made of copper,
iron, lead, or any other suitable metal, which may be either cast or bent. In said
piece a I place edgewise and longitudinally a piece of wood b, to the under or lower
edge of which I fasten by screws c, c, Figure 1, or other convenient attachments
the herein before mentioned semi-cylindrical piece a. Over the top edge of said
piece of wood b, and fastened thereto by screws c', c', Figure 1, or other convenient
attachments, I place two or more pieces d, d, Figure 1, of zinc, lead, copper, or any
other suitable sheet or cast metal, which form an elliptical capping of a diameter
corresponding to that of the herein before described piece a. These pieces forming
such capping may be made as shown e, e, Figure 2, and f, f, Figure 3, respectively.
One of them overlaps the other, as shown at e¹, Figure 2, and f', Figure 3, and g,
Figure 4, respectively. The top of the piece so overlapped forms a rest or stop
for the square of glass or other covering when either is placed in the sash-bar, as
shewn at e, Figure 2, and f1, Figure 3, respectively. Each square of glass. or other
covering is inserted edgewise at. each of its sides between a piece of capping d,
Figure 1, e, Figure 2, or f, Figure 3, and the hereinbefore mentioned piece a,
Figure 1. The piece of capping is then bent or pressed at each of its sides, as
shewn in Figures 1, 2, 3, & 4, and by these means, combined with the rest or stop
provided by the overlapping of the piece d, Figure 1 (and also shewn at e¹,
Figure 2, and f', Figure 3), the square of glass or other covering is held tightly in
position, and so as perfectly to exclude water, and yet with sufficient looseness to
avoid any risk of breakage under changing temperature or the like cause. This
plan of making my sash-bar does not limit ne to any particular size of pane or
square of glass. The interior of the herein before mentioned piece a, Figure 1,
forms a gutter for carrying off water which is discharged over the succeeding
square of glass or other covering. For the purpose of carrying off condensed water,
the squares of glass are preferably cut in bevelled form as shewn in Figure 3, but
they may be cut square, as shewn in Figures 2, 4, & 5, and the hereinbefore
described piece a, Figure 1, may if desired form a channel of ventilation, or be
closed at pleasure. The piece of wood b hereinbefore described may be prepared or
pickeled with tar or other suitable preserving compound so as to be rendered less
liable to decay than ordinarily from the action of water, and tar, paint, or other
protective compound may be poured through the aforesaid piece a so as to further
protect said piece of wood b. For fastening the improved sash-bar to the ridge-piece, I
bore a hole of suitable size in the latter and cut a slot from the outer edge thereof to

page_text: such hole. This hole is of sufficient circumference to receive the top of the sash-
bar therein, which top may project above the ridge-piece. The piece of wood b
herein before described projects beyond the top of the aforesaid capping d, d,
Figure 1, fits tightly in the aforesaid slot, and is fastened by screws or other
couvenient attachments to the said ridge-piece. The bottom or lower end of the
said sash-bar is secured to the bottom wall plate by similar means to those lastly
described.
Having now fully described the nature of my said Invention and the means by
which the same is to be carried into effect, I wish it to be understood that what I
consider new and therefore secured to me by the hereinbefore in part recited
Letters Patent is, substantially as is hereinbefore stated and illustrated in the
accompanying Drawings.
In witness whereof, I, the said William Howitt, have hereunto set my hand
and seal this Seventh day of January, in the year of our Lord Onc
thousand eight hundred and eighty two.
WILLIAM HOWITT. (L.S.)
