Improvements.in Dry Glazing.
We THOMAS LITTLEHALES, of Lyndale, Thornhill Road, Handsworth,
Staffordshire, Manufacturer, and GEORGE MARTIN, of 19 Carlyle Road, Edgbaston.
Birmingham, Glazier, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in glazing, and consists in certain improve-
ments in the sectional shapes of the metallic caps (top and bottom.) which are
employed to receive and accommodate the glass, and of the means of securing, such
caps to the sash bars. Usually the sectional shape of sash bar employed is that of
a crucifix. Upon this is secured the bottom cap upon which rests the glass.
Hitherto this cap has been so made as to require holes being made at intervals in
the top rib of the sash bar and screwthreaded to receive screw pins by which..the
whole has been secured together.
In' this invention however the said cap is so shaped as to provide a rib or flange
which shall fit close underneath the two side ribs of the sashbar. It is funther
arranged that the beforementioned securing pins shall be provided with wedge
shaped like heads, and the said pins to be passed through the holes in the cap from
the inside thus presenting their wedge shaped heads to the top of the ash bar.
Hence when the said cap is slid ou to the sash bar end wise, these said wadgeishaped
heads serve to bind and secure the said cap tightly in position. The serewpontion
of these pins further serve to secure the top cap in the usual manner.
Again. In some instances, these said bottom caps may ibedformed in such¸<a
manner as that they shall serve to form a better cushioned or elastic support to the
glass in which case the metal-of the-cap-is curried down the side of thessashibar,
then bent outwards and so on to form the condensation channel, and from thence
upwards in an outwardly inclined somewhat ogee shape for a short distance, thence
terminating in a horizontal portion upon which latter rests the glass. Thus beneath
this horizontal supporting portion is formed a springy or cushion-like support.
Further. In order to secure this shaped cap in position, ca saddle like, piece is
secured by soldering or otherwise to the inside of the upper part of the cap, rso,
that its two legs reach down each side of the upper rib.of the sash bar, and there
terminate in. hook like forms; which shall engage with projections formed upon or
attached to the said upper rib of the sash bar. A convenient way of effecting this,
would be to pierce transverse holes at corresponding intervals in the iban, and insert
pins or 1ollers or other suitably shaped pieces which shall project upon each side,
and, with which the aforesaid hooklike parts may engage.
In some cases such top and bottom; caps may be formed in one piece as follows:-
Commencing for instance at the one (lower) side, the metal is formed into the
condensation channel, thence upwards to form the support for the glass, whence it
is bent in a doubled form and back to or near the centre and thence over the crown
or top of 'the sash bar and down the other side in: the same manner. The before
mentioned doubled portion when first made is left in a nearly upright position soi as:
to admit the glass, and then turned down on to or upon the glass, thus forming the
top cap: At the part where the condensation channel is..forined, the metal.
(particularly when made of lead) is made doubled, and between such doubled -part

page_text: a lining of stronger metal is inserted so that thereby it is considerably strengthened
while at the same time such strengthening piece is not exposed.

Improvements in Dry Glazing.
We THOMAS LITTLEHALES, of Lyndale, Thornhill Road, Handsworth,
Staffordshire, Manufacturer, and GEORGE MARTIN, of 19 Carlyle Road,
Edgbaston, Birmingham, 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 relates to improvements in glazing, and consists in certain
improvements in the sectional shapes of the metallic caps (top and bottom) which
are employed to receive and accommodate the glass, and of the means of securing
such caps to the sash bars.
In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference.
In Figs. 1 and 2, the bottom cap 8, is bent and shaped so as to provide the
flange 9, which fits tightly beneath the side ribs 10, 10, of the sash bar 11, so that
the said ribs 10, 10, are clipped top and bottom by the said cap. 12, 12, are the
condensation channels. 13, is the glass which rests upon the bottom cap and is
further held down by the top cap 14. This top cap is secured thereto as
follows 15, is a securing pin, a number of which are used at given distances
apart, this pin is provided with a thin wedge shaped head (or what perhaps might
be termed a shoe) 16.. A hole is made in both the top and bottom cap through
which the said pin may pass. The said pins are first passed through the bottom
cap, and the latter is slid along the sash bar end wise, these said wedge shaped
heads serving further. to tighten the
cap thereon.
The top cap. 14, is now placed
in position upon the pins 15, and covering nut 17, are screwed thereon which fully
secures them. together..
--
Again, as shown in Fig. 3, in some instances, these said bottom caps may be.
formed in such a manner as that they shall serve to form a better cushioned or
elastic support to the glass, in which case 11a, is the. sash bar having the two
side ribs, 10a, 10u... The metal of the cap 8a, is carried down each side of the
sash bar, then bent outwards and so on to form the condensation channels 12a, 12a,
and from thence upwards in an outwardly inclined somewhat ogee shape at 18, for
a short distance, thence terminating in a horizontal portion 19, upon which latter
rests the glass. 13a. Thus beneath this horizontal supporting portion is formed a
springy or cushion-like support.
Further. In order to secure this shaped cap in position, a saddle like piece 20,
see Figs. 4 & 5, is secured by soldering or otherwise to the inside of the cap, so
that its two legs terminate in hook like forms 21, 21, which shall engage with
projections 22, formed upon or attached to the said upper rib of the sash bar.
A convenient way of effecting this, would be to pierce transverse holes at corre-
sponding intervals in the bar, and insert pins or rollers or other suitably shaped
pieces which shall project upon each side, and with which the aforesaid hooklike
parte may.engage..
It will be seen that in Fig. 4, a side view of the hooks are shown separate from
the bar and cap, while in Fig. 5, the said hookpieces are shown upon the bar
without the cap. In some cases such top and bottom caps may be formed in one
piece as shown in Fig. 6. Commencing for instance at 23, on the one (lower) side,

page_text: the metal is formed into the condensation channel 126, thence upwards to form
the support 19a, for the glass 136, whence it is bent in a doubled form at 24, and
back to or near the centre and thence over the crown or top of the sash bar and
down the other side in the same manner. The before mentioned doubled
portion 24, when first made, is left in a nearly upright position, as seen in dotted
lines, so as to admit the glass, and then turned down on to or upon the glass, thus
forming the top cap. At the part where the condensation channel is formed, the
metal (particularly when made of lead) is doubled, and between such doubled part
a lining 25, of stronger metal is inserted so that thereby it is considerably
strengthened, while at the same time such strengthening piece is not exposed.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination with a bottom cap for glazing purposes, such as those
herein referred to, having condensation channels 12, 12, of the doubled under
flange 9, substantially as shown and for the purposes specified.
2. In glazing apparatus such as herein referred to, securing the top cap to the
bottom cap by means of the pin 15, baving the thiu shoe like head 16.
3. The improved sectional shape of bottom cap as shown in Fig. 3, in which is
formed the cushion parts 18, 18, as set forth and shown.
4. Making the top and bottom caps in one piece of metal substantially as by
the sectional shape shown and described in Fig. 6.
5. Securing the bottom caps of glazing apparatus to their sash bars by means of
down-hanging hooks such as 21, 21, taking underneath projections such as 22, 22,
substantially as described and shown.
