Improvements in Appliances connected with Glazing.
We, EDWARD BOYCE PODMORE, Managing Director, and JOIN EDWARD WRIGHT,
Foreman, and the Firm of HELLIWELL AND COMPANY LIMITED, all of Birds Royd,
Brighouse, in the County of York, Patent Glaziers and Zinc Roof Manufacturers,
do hereby declare the nature of this invention to be as follows:-
This invention consists of an improved construction, arrangement, and com-
bination of appliances for carrying or supporting and for holding in position
sheets of glass in roof and like glazing.
According to this invention the carrying and supporting bar is of T section,
the lower portion or web of which we prefer instead of being made deep vertically
should be shorter and terminate in a bulb or enlargement which will afford the
requisite strength. The head or horizontal arms of the T are provided with
longitudinal grooves or channels and a packing of asbestos is applied to each
groove as usual and on which packing and arms the sheets of glass rest, their
inner edges abutting against an upper web which forms a partition and also serves
to carry the cap screws or chased bolts hereinafter referred to.
The cap or cover as a part of the present invention consists of a metal strip
rolled in the form (on cross section) of a hollow rectangle which may be convex
on its upper surface and having at its underside a longitudinal opening or con-
tinuous slot way, whilst from its outer and lower sides outwardly and continuously
in the length of the cap are extensions which rest upon the upper surface of the
glass and in each of which extensions is a longitudinal groove having asbestos
or other like packing.
The hollow space within the cap is occupied and nearly filled by a rectangular
bar of metal, or wood, or other substance, the under surface of which bar rests
upon the upper vertical web of the supporting bar, and the upper surface of such
bar may be convex when a convex cap or cover is employed, the whole being
securely bound and fastened together by means of the screwed or chased bolt
above referred to which passes through the rectangular bar and through the
centre of the cap or cover. The head or lower part of the screwed or chased
bolt is secured to the vertical web of the supporting bar by forming it after the
manner of a dovetail or 1 which is rivetted or otherwise fixed into the bar: and
the bolt hole through the rectangular bar and through the cap or cover is oblong
or slotted so as to provide for expansion and contraction of any of the metallic
parts of the appliance, the slots being covered by the washers of the securing
nuts, and the said washers are made from lead or other material so as to exclude
entrance of moisture.
The asbestos packing instead of being laid in channels or grooves, may be laid
flat between the cap or cover and the adjacent edges of the glass.

We, EDWARD BOYCE PODMORE, Managing Director, JOHN EDWARD WRIGHT,
Foreman, and the Firm of HELLIWELL AND COMPANY LIMITED, all of Birds Royd,
Brighouse, in the County of York, Patent Glaziers and Zinc Roof Manufacturers,
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 of an improved construction, arrangement, and com-
bination of appliances for carrying or supporting and for holding in position
sheets of glass in roof and like glazing.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a cross section of the improved appliances and glass complete.
Fig. 2 is a like view to Fig. 1, but shewing bulb or enlargement at the lower
extremity of the web to afford rigidity and extra strength and to avoid deflection.
This view also shews the lower part of the metal cup formed to the required shape
by return folds of the sheet metal as distinguished from the lower part of cap
at Fig. 1 (see also details).
Fig. 3 is an oblique longitudinal view, the front being shewn in section.
The remaining illustrations are of parts or details shewn separately.
According to this invention the carrying and supporting bar 1 is of T section,
the lower portion or web 2 of which we prefer instead of being made deep
vertically, should be shorter and terminate in a bulb or enlargement 3 which
will afford the requisite strength. The head or horizontal arms of the T are
provided with longitudinal grooves or channels 4, and a packing of asbestos 5
is applied to each groove as usual, and on which packing and arms the sheets
of glass G rest, their inner edges abutting against an upper web 7 which forms a
partition and also serves to carry the cap screws or chased bolts 8 hereinafter
referred to.
The cap or cover 9 as a part of the present invention consists of a metal strip
rolled in the form (on cross section) of a hollow rectangle, which may be convex
on its upper surface, and having at its underside a longitudinal opening or con-
tinuous slot way 10, whilst from its outer and lower sides outwardly and con-
tinuously in the length of the cap 9 are extensions 11 which rest upon the upper
surface of the glass 6, and in each of which extensions is a longitudinal groove 12
having asbestos or other like packing 5.
The hollow space 13 within the cap is occupied and filled by a rectangular bar
of metal, or wood, or other substance 14, the under surface of which bar rests
upon the upper vertical web 7 of the supporting bar 1, and the upper surface of
such bar 14 may be convex when a convex cap or cover is employed, the whole
being securely bound and fastened together by means of the screwed or chased
bolt 8 above referred to, which passes through the rectangular bar 14 and through
the centre of the cap or cover 9. The head or lower part of the screwed or
chased bolt 8 is secured to the vertical web 7 of the supporting bar 1 by forming
it after the manner of a dovetail or T 15 which is rivetted or otherwise fixed into
the web 7, and the bolt hole 16 through the rectangular bar 14, and through the
cap or cover 9, is oblong or slotted so as to provide for expansion and contraction
of any of the metallic parts of the appliance, the slots 16 being covered by the
washers 17 of the securing nuts 8, and the said washers are made from lead or
other compressible material so as to exclude entrance of moisture.

page_text: The asbestos packing 5 instead of being laid in channels or grooves, may be
laid flat between the cap or cover 9 and the adjacent edges of the glass 6.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare. that what
we claim is :-
The apparatus for purpose aforesaid comprising the several parts, all in
combination and as shewn by the drawings annexed and as herein fully described.
