Improvements relating to Non-conducting Sectional Coverings for
Boilers and the like.
We, EDWARD TAYLOR and SWAINSON THOMPSON TAYLOR, Junior, trading as
S. T. Taylor & Sons, Cement Manufacturers, Scotswood-on-Tyne, in the County
of Northumberland, do hereby declare the nature of this invention to be as
follows:-
This invention consists in improvements relating to non conducting sectional
coverings for boilers and the like.
The sectional coverings are generally known as mattresses and are composed
of silicate of cotton or other material or composition that acts as a non conductor
of heat.
The improvements consist in the method and means of connecting the mattresses
together and fixing them to the boiler or other surface. The mattress is made
of any suitable size. It rests upon and is connected to an open frame consisting
of two or more thin flat steel or other metallic bands running lengthwise and
two or more similar bands running breadthwise fastened together at the inter-
sections. The number of bands and their distance apart are regulated by the
size of the mattress. Laces of copper wire or other suitable material fasten the
non conducting material to the frame in which suitable holes are provided. The
ends of the bands are made so that they can be easily connected or disconnected
to or from similar bands or other mattresses and a continuous covering can be
made by joining several together. This connection may be in the form of a
hinge the pin being fixed in the end of one band and the end of the correspond-
ing band shaped like a hook to engage on the pin, or the ends of the engaging
bands may be bent back on themselves and fit into each other, or the end of one
band may be hook shaped and fit into a slot or hole in the end of the correspond-
ing band, or the ends may be formed in any other simple manner
or disconnected. The band ends.
SO that they can be easily connected
which come against the horizontal angle bars generally provided on boilers for
fixing non conducting material are provided with bolts or other means for adjust-
ment which pass through or are connected to the angle bars.
The mattresses are laid on or against the boiler surface with the framing out-
wards, and all connected to-gether by means of the hinges, hooks or other fasten-
ings at the end of the bands, then tightened up against the boiler by the adjusting
screws through the angle bars. If at any time it is necessary for examination
or other purpose to remove part of the covering any one mattress can be removed
by simply slackening the adjusting bolts near, and unhinging the mattress, the
adjoining mattresses having no tendency to displacement.

We, EDWARD TAYLOR and SWAINSON THOMPSON TAYLOR, Junior, trading as
S. T. Taylor & Sons, of Scotswood-on-Tyne, in the County of Northumberland,
Cement Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists in improvements relating to non conducting sectional
coverings for boilers and the like.
The sectional coverings are generally known as mattresses, and are composed
of silicate of cotton or other material or composition that acts as a non-conductor
of heat.
The improvements consist in the method and means of connecting the mattresses
together and fixing them to the boiler or other surface. The mattress is made
of any suitable size. It rests upon and is connected to an open frame consisting
of two or more thin flat steel or other metallic bands running lengthwise and
two or more similar bands running breadthwise fastened together at the inter-
sections. The number of bands and their distance apart are regulated by the
size of the mattress. Laces of copper wire or other suitable material may be
used to fasten the non conducting material to the frame in which suitable holes
are provided, but it is preferred to use a thin rivet or piece of wire passed through
the frame intersections and the material clinched or riveted over at both ends,
for this purpose, as being more effective and convenient in application. The
ends of the bands are made so that they can be easily connected or disconnected
to or from similar bands on other mattresses, and a continuous covering can be
made by joining several together. This connection may be in the form of a
hinge, the pin being fixed in the end of one band and the end of the corresponding
band shaped like a hook to engage on the pin, or the ends of the engaging bands
may be bent back on themselves and fit into each other, or the end of one band
may be hook-shaped and fit into a slot or hole in the end of the corresponding
band, or the ends may be formed in any other simple manner so that they can be
easily connected or disconnected. The band ends which come against the
horizontal angle bars generally provided on boilers for fixing non-conducting
material are provided with bolts or other means for adjustment which pass
through or are connected to the angle bars, or the adjustment may be between
two mattresses.
The matresses are laid on or against the boiler surface with the framing out-
wards, and all connected together by means of the hinges, hooks or other fasten-
ings at the ends of the bands, then tightened up against the boiler by the adjust-
ing screws through the angle bars, or by adjusting means between two of the
mattresses.
If at any time it is necessary for examination or other purpose to remove part
of the covering, any one mattress can be removed by simply slackening the
adjusting bolts etc. near, and unhinging the mattress the adjoining mattresses
having no tendency to displacement.
In the annexed drawings Fig. 1 is a part elevation of a boiler with mattresses
attached. Fig. 2 is a plan and Fig. 3 a section of the mattress. Figs. 4 & 5,
6 & 7, 8 & 9 are elevations and plans of connections of mattress marked A, B & C
respectively on Fig. 1. D is the nonconducting material; E the bands of the
frame; F a hook bolt through the angle bar G on the boiler H; J lugs or turned

page_text: up ends of the bands E. K adjusting bolts through the lugs J; L hooked end
of band; M shows the ends of the bands formed to take the hinge pin N; P are
washers which may be long or large enough to take two or more rivets or wires
and Q rivets or wires through the intersections of frame and non-conducting
material D clinched over at the ends.
The drawing shews the mattresses fixed to the under side of a boiler but it is
ovident that the invention can be applied to the whole circumference of the boiler,
and also to flat surfaces of tanks and the like.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-

1. Improved means for connecting and fixing non-conducting coverings or
mattresses to boilers, tanks and the like, consisting of an open frame of cross
bands suitably attached to each other at their intersections to which is fastened
by rivets or otherwise the non-conducting material of the mattress, such mattresses
being connected to each other by suitable detachable devices to form a con-
tinuous covering of which the mattresses are separately removable.
2. Improved means for connecting and fixing non-conducting coverings or
"mattresses" to boilers, tanks and the like, consisting of an open frame of cross
bands suitably attached to each other at their intersections to which is fastened
by rivets or otherwise the nonconducting material of the mattress, said bands
being bent over at one or each end to engage a hinge pin or each other or bent
outwards in the form of lugs for the passage of bolts or the like.for purposes of
attachment or adjustment, and being attachable to an angle bar or the like on the
boiler by a hook bolt or other suitable device engaging the before mentioned
hinge pin or band ends substantially as illustrated and described.
