We JAMES ASHTON FLETCHER and SAMUEL FLETCHER both of Borough Brass
Works, Ashton-under-Lyne, Brass Founders do hereby declare the nature of this
invention to be as follows:-
Our said invention relates to improvements in protectors or shields for water gauges
of boilers.
The object of such a protector is to prevent accidents in the event of a gauge glass
bursting by confining the fragments.
According to our said invention we provide a metal frame containing slots or
grooves into which are slid plates of glass which partly surround the gauge glass.
In front of the plates of glass we place a grating or cage of wire.
Gauge glass shields having protecting plates of glass have been well known for
many years but are subject to the defect that in case of the bursting of the gauge
glass the protector glasses are often broken and blown out.
By combining with the protector glass a separate grating or cage of wire the flight
of the pieces of the protector glass is arrested in the event of the latter becoming
broken by the fragments of the broken gauge glass.
By simply sliding the plates into slots or grooves they may be easily withdrawn for
cleaning without removing either the grating or the protector case. We attach the
protector to the gauge by means of slots engaging behind the heads of the cleaning
plugs or screws. The said slots are enlarged at the end to enable the protector to
pass over the heads of the cleaning screws.
Dated this 9th day of March 1896.

and lower ends slots or grooves a¹ into which are slid plates of glass b so as to partly
surround the gauge glass c. We may in some cases extend the slots or grooves a¹
along each side of the frame a as shown in section at Fig. 3. In front of the plates

Gauge glass shiolds having protecting plates of glass have been well known for many
years but are subject to the defect that in case of the bursting of the gauge glass the
protector glasses are often broken and blown out but by combining with the protector
glasses 6 a separate grating or cage of wire d the flight of fragments of glass
arrested.
By simply sliding the protector glasses into slots or grooves a¹ they may be
easily withdrawn for cleaning without removing the protector frame a. To enable.
the protector to be attached to the gauge the frame a is provided with slots e e¹ which
engage behind the heads of the usual cleaning plugs or screws f f of the gauge.
The upper slot e is enlarged at one end to enable the protector frame to pass over the
head of the cleaning screw f. On the frame being lowered the upper parts of the
slots will engage behind the heads of the cleaning plugs and keep the guard in
position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.―
1. A water gauge glass protector substantially as set forth and shown.
2. The combination of a grooved metal frame a wire guard and glass plates
substantially as and for the purpose set forth and shown with reference to the
accompanying drawings.
3. In a gauge glass protector a frame a slotted as shown for facility of attachment
and removal substantially as set forth and described.
