PROVISIONAL SPECIFICATION.
Improvements in Fire-guards and applicable to other analogous
purposes.
We, LEWIS COOPER, of 182, High Street, Stratford, E., Mechanic, and ROBERT
GILBERT SHARMAN, of 23, Wolseley Road, Forest Gate, E., Mechanic, do hereby
declare the nature of this invention to be as follows;
-
Our invention relates to improvements in fire-guards, and more especially to those
for domestic use, it is however applicable to other analogous purposes, such as the
protection of machines. In carrying our invention into effect, we proceed in or in
about in the following manner, assuming it is applied to a domestic fire-guard,
but without restricting it to that one use. To the inside or outside of the fender
we attach in any suitable manner one end of a "lazy-tong" arrangement, or the
ends of more than one such arrangement. The other end of the said arrangement
or the other ends of the arrangements is or are attached to a suitable rail which
when the guard is drawn up for use will be the upper rail, and when shut down
may rest on the upper edge of the fender. The "lazy-tong" arrangement may be
provided along the front and also at the return ends of the fender. There may
be also intermediate rails as well as the top one already mentioned.
We sometimes provide bars or a bar attached to the rail or rails or to the "lazy-
tong" arrangements so that they or it may be placed vertical, in which case the
guard will be kept from collapsing, or horizontally, when the guard is to be shut
down. These supporting bars may be pivotted or hinged to the fender instead of
to the lazy-tongs or to the rails, and they may be arranged so as to assume a
diagonal position when the guard is drawn up to the desired height for use. As
a further mode of stiffening the guard when in use diagonally or otherwise
arranged, slotted rods may be provided at the return ends of the guard or fender
and hinged to the top or other rail and fastened by tightening up studs or screws
working in the slots.
Instead of attaching the "lazy-tong" or other arrangement or arrangements
directly to the fender, it or they may be attached to separate parts for fixing to
any fender.

Our invention relates to improvements in fire-guards and applicable to other
analogous purposes and in carrying it into effect we proceed in or in about the
following manner assuming it to be applied as a domestic fire-guard but without
restricting it to that one use. In order to more clearly explain the invention we
make reference to the accompanying drawings in which Fig. 1 is a vertical
section, Fig. 2 an isometrical view of half of a fire-guard. Fig. 3 a cross section
of "runner
to be hereinafter mentioned, and Fig. 4 a side view of rule-jointed
rods to be referred to in the following description. To an angle-iron a fastened
to the inside of the fender 6 we attach in any suitable manner one end of a "lazy-
tongs c or the ends of a number of such lazy tongs. The other end or ends of
the said arrangement or arrangements is or are pivotted to a suitable rail d which
when the guard is drawn up for use will be the upper-rail and when shut down
will rest on the upper edge of the fender b. We propose to provide these lazy
tongs arrangements at the return ends as well as the front of the fender. In
order to keep the arrangement from collapsing when opened up for use we provide
the horizontal bars e and f and an intermediate one g. The bars ef and g are
pivotted to the crossing points of the bars of the lazy tongs c and to keep those
bars rigidly apart we employ vertical bars h which are rule-jointed at i, and at
their outer ends pivotted to e and f. Behind the bar g are the runners j in which
are bolts & passing through the rule joints and furnished with wing heads l. The
bolts are screw threaded and work in an internally screw threaded bush k¹
passing loosely through the rule joints i. The bolts are also burred over at k³
to prevent their being screwed right out. The runners ; are turned over at the
upper and lower edges so as to be free to slide along the chamfered parts m on
the intermediate bar when the guard is being shut down. In order to facilitate
the shutting up of the guard we may make the rule joints such that when the bars h
are fully drawn up they will be at an angle with instead of vertical to the bars e f
and g (see Fig. 4) and we particularly purpose doing this with the bars h at the
return ends of the guard. A channelled or slotted intermediate bar may be used
instead of the chamfered one above mentioned.
Assuming the guard to be shut down in the fender, it is brought into use by
raising the rail d and when it has been brought to its greatest height the bolts k
are tightened up against the bar g by turning the winged heads, thus keeping
the whole rigid until such time as it is required to shut down the guard when
the bolts are slackened and the rail & pushed down.
Similar arrangements of lazy tongs may be employed as guards for machinery
or otherwise, in which case, instead of shutting down into a fender the guard
can be shut down into a channel in the floor and the rail d may then be of such
form as will close the mouth of the said channel.
We do not confine ourselves to the precise shape relative proportions or dis-
positions of parts as shown in the drawings as any or all of them may be con-
siderably varied without departure from the essential features of our invention.
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: -
1. Improved fire and other guards consisting essentially of a vertically expanding
lazy-tongs or of several vertically expanding lazy-tongs pivotted at one end to an
angle iron for fastening to a fender or elsewhere and at the other end pivotted to a
rail, intermediate horizontal rails or bars being pivotted to the crossing-points of
the bars of the lazy tongs and vertical rule jointed bars being provided for
keeping the guard rigidly extended, the said rule-jointed bars having
runners and bolts working on or in chamfered parts of the middle
horizontal rail or in slots or channels provided therein, the bolts being

page_text: furnished with wing headed nuts for tightening up the said rule-jointed bare,
the whole provided for and operating substantially as described in the above
specification and exemplified as regards a fire guard in the accompanying drawings.
2. The combination of parts substantially as described in the above specification
and exemplified in the accompanying drawings and together forming fire &
other guards.
