Improvements in Devices suitable for Protecting Water-gauge Glasses
We, JOHN BASIL HOPE, M.I.M.E., of 6 Hillary Place, Leeds, in the County of
York, Engineer, and THOMAS WILLIS SANDERS, of 5, Blenheim Square, Leeds,
aforesaid, Commission Agent, do hereby declare the nature of this invention to
be as follows:
This invention relates to devices suitable for protecting the water-gauge glasses
of locomotive and other boilers from being accidentally broken, and also for pre-
venting the particles of glass from flying about to the injury of the attendants
when such glasses do break or happen to burst.
A gauge-glass protector according to our invention comprises two metallic
spring-clips connected together by wires and adapted to be readily placed on or
over, and removed from the top and bottom nuts of a water-gauge glass, and, when
placed thereon to clamp themselves securely thereto. Each of the wires that
connect the clips together, is secured at each end to the corresponding clip by
passing it round the clip and securing its end, as by twisting, to its body-portion.
The connecting wires, of which there may be any suitable number, are themselves
connected together and kept at suitable distances apart by ess-shaped wires, each
of which is secured at one end to one of the said connecting wires whilst its other
end is secured to an adjacent connecting wire. Each two adjacent connecting
wires being thus connected together.
The spring-clips of a protector according to this invention may, however, before
being bent to shape, hardened, and tempered, be each provided near one edge with
perforations in which the ends of the connecting wires are secured.
Each clip may advantageously be formed from a flat strip of metal by bending
it transversely so that it shall have in plan the form of an open ring having one
or more external open-loop like portions adapted to impart to the clip the required
flexibility.
In placing a protector according to this invention in position on the nuts of a
gauge-glass, each clip is opened out sufficiently and passed over the corresponding
nut, whereupon, on being released, it suddenly contracts and securely grips the
nut.

page_text: aforesaid, Commission Agent, 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 devices suitable for protecting the water-gauge glasses
of locomotive and other boilers from being accidentally broken by contact there-
with of an external body, and also for preventing the particles of glass from flying
about to the injury of the attendants if such glasses should break or burst by
reason of the pressure therein.
A gauge-glass protector according to our invention comprises two metallic
spring-clips connected together by wires and adapted to be readily placed on or
over, and removed from the top and bottom nuts of a water gauge glass, and, when
placed thereon to clamp themselves securely thereto. Each of the wires that
connect the clips together, is secured at each end to the corresponding.clip by
passing it round the clip and securing its end, as by twisting, to its body portion.
The connecting wires, of which there may be any suitable number, are themselves
connected together and kept at suitable distances apart by ess-shaped wires, each of
which is secured at one end to one of the said connecting wires whilst its other
end is secured to an adjacent connecting wire, each two adjacent connecting wires
being thus connected together.
The spring-clips of a protector according to this invention may, however, before
being bent to shane, hardened, and tempered, be each provided near one edge with
perforations in which the ends of the connecting wires are secured.

Each clip may advantageously be formed from a flat strip of metal by bending
transversely so that it shall have in plan the form of an open ring having
more external open-loop like portions adapted to impart to the clip the required
flexibility. In placing a protector according to this invention in position on the
nuts of a gauge-glass, each clip is opened out sufficiently and passed over the
corresponding nut, whereupon, on being released, it suddenly contracts and securely
grips the nut.
In the accompanying drawings,
Figs. 1 and 2, show respectively in plan and side elevation a water-gauge glass
protecting device according to our invention, and
Figs. 3 and 4 are views of parts of the same drawn to a larger seale.
1 and 2 are the spring clips, each consisting of a flat strip of metal such as steel
bent to the shape of an open ring having three open loop portions 3. The two
clips are connected together by wires 4 the end portions 5 of which are passed
round the respective clips and secured to the intermediate portions by twisting
them around such intermediate portions as shown in Figs. 2 and 4. The clips
are preferably held at the required distance apart by means of stay wires or rods 6
that fit tightly into eyes formed at the ends of the clips as shown.
The connecting wires 4 are kept at the requisite distance apart by ess-shaped
wires 7 or by wires 8 (Fig. 3) having loop-shaped ends projecting in the same
direction.
In Figs. 5, 6 and 7 which are respectively, a plan, an elevation and a vertical
section of modified form of protecting device according to this invention, the
spring clips 1 and 2 are bent to the form of open rings, having formed in each
of them one open loop portion, 3, these. being rigidly secured together at the
requisite distance apart by the stay wires or rods 6. In each clip 1 and 2 near
their respective edges 9 and 10 are perforations 11, in which are inserted and
secured the connecting wires 12 as shown in Fig. 7. In this case, connecting.
wires 7 such as shown in Figs. 2, 3 and 4 are unnecessary.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we ueclare that what
we claim is:-
1. Devices suitable for protecting water-gauge glasses comprising two metallic
spring clips connected together by wires substantially as hereinbefore described

page_text: with reference to and shown in Figs. 1 to 4 inclusive of the accompanying drawings.
2. Devices suitable for protecting water-gauge glasses comprising two metallic
spring clips each provided near one edge with perforations in which the ends of
the wires connecting the two clips together are secured substantially as herein-
before described with reference to and shown in Figs. 5 to 7 inclusive of the
accompanying drawings.
