Improvements in Steam Boilers.
I WILLIAM M. GLASSON of Socorro in the County of Socorro and State of New
Mexico United States of America Machinest 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 my invention relates to certain new, and useful improvements in steam-
boilers, and it has for its objects to improve upon prior devices of this character, to
provide a water compartment around the top and sides of the boiler below the water
line and to otherwise improve upon the construction of steam boilers.
The novelty resides in the peculiar combinations and in the construction, arrange-
ment, and adaptation of parts, all as more fully hereinafter described, shown in
the drawings, and then specifically defined in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which with the
letters of reference marked thereon, form a part of this specification and in
which;
Fig. 1 is a side elevation of a boiler constructed in accordance with my invention..
Fig. 2 is a central longitudinal section. Fig. 3 is a transverse section, and Fig. 4 is
a front elevation, of the same.
Reference now being had to the details of the drawings by, letter, A designates
the base and B the outer vertical walls provided with suitable holes a for the
purpose of cleaning out the water-jackets or compartments and removing sediment
when occasion may require. These holes are covered by means of suitable covers as
shown.
C'is the boiler provided with longitudinal flues C which are open at their ends
and are supported between their ends within the boiler by means of the support b.
D is the blow-off tube or pipe extending along the bottom of the boiler, preferably
one inch from its bottom and perforated upon its under side in order to remove the
sediment when desired.
E is a water compartment or jacket surrounding the boiler and extending below the
water line thereof it is secured to the boiler by means of flanges or angle irons C
and suitable securing means, as rivetting. The angle irons or flanges of the water
compartiment are rivetted to the main sheet' of boiler, and the sheet of compartment
rivetted to said angle-irons or flanges said angle-irons forming the bottom of water-
compartment and the support of the boiler. On its side walls are water pockets for
the extreme length of the same.
The upper row of tubes E¹ are extended through the walls of the water compart-
ment, and one inch from the bottom of the same. The top tiers of flues are safety
flues of the boiler. If the water gets below the flues and the flues burst the water in
the compartment will protect the main sheet of boiler from burning and prevent a
boiler explosion from low water. The top end of boiler is stayed by means of diagonal.
stays f.
Gis a water-inlet pipe connected with a suitable source of supply, and emptying

page_text: His a feed pipe connected to the water compartment A of the boiler, entering
through the top of the boiler and secured to the sheets thereof, and passing around
the boiler on the inside thereof, and “extending a short distance along the bottom of
the boiler, and is perferably perforated as shown so as to provide a spray feed within
the boiler.
I is a smoke-stack providing an outlet for the products of combustion.
J is a fire-box provided with the grate h and K is the ash-pot said fire box and
ash-pot being provided with suitable feed or fire-doors i and j as shown.
L is the outer water-jacket or compartment entirely surrounding the boiler and
extending down upon all sides of the furnace. The feed pipe of the boiler is provided
with suitable valve m as shown.
M M are suitable supports for the boiler on which the angle-irons or flanges n of
the water-compartment rest.
N is the manhole-head of the boiler.
O is a suitably hinged door at the end of the furnace to provide access to the flues
of the boiler when necessary.
P is the flue-plate on the back end or side of the boiler to direct the draft and
products of combustion through the flues. It will be seen from the above description
that I provide a boiler that will have at least one have half more heating surface
than any boiler now in use, for its heating surface extends along the bottom of the
boiler and up the sides and along the bottom of the water compartment thence
through the flues and up the entire end, thence along the top and sides down to the
projecting-sheets of the bottom of the inner water-compartment of the boiler the
entire length of the same, and this boiler will be stronger than any boiler that is
now in use on account of the double sheets on the top and sides and ends, down
below the water-line of the boiler. If the water gets below the flues in the boiler, the
water in the compartment will protect the sheets of the boiler from burning, as the
water in the compartment will be below the top tier of flues on the outside and will
so protect the sheet from burning.
The arrows represent the draft or heating surface of the boiler. The water in
compartment on top of the boiler will not affect the steam in the boiler, as the water
will be nearly at a boiling temperature forced in by the steam-pump from the outside
water-pockets, and by the extra length of its heating surface it will consume
at least seventy-five per-cent. more of smoke than any boiler that is now in use without
a smoke consumer for this boiler can be built of any desired length with perfect
safety as the weight of the boiler will rest on its side walls or water jackets for the
extreme length of the same. This boiler is entirely surrounded by water com-
partments.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed. I declare that what
I claim is
1. The combination, with the boiler and its tubes, of the water compartment
surrounding the same and extending below the water-line, the upper row of tubes
being extended through said water-compartment, substantially as shown and
described.
2. The combination, with the boiler, of the water-compartment around said boiler
and secured thereto below the water-line, and the upper set of 'tubes extended through
the ends of the boiler and through the ends of the water-compartment and one inch
from the horizontal portion thereof, substantially as shown and described."
3. The combination of the boiler, with its water compartment, of the tubes extended
through the end of the boiler, and through the ends of the water-compartment,
and the outer water jacket or compartment surrounding said boiler and the furnace,
as shown and described.
4. The combination of the boiler with its water-compartment, of the tubes
extended through' the ends of the boiler and through' the ends of the water-com-
partment, and the outer water-jacket or compartment surrounding said boiler and

page_text: the furnace, as shown and described and the blow off pipe extending the full length
of boiler, and one inch from the bottom of same, with holes in bottom of said
pipe to receive the sediment that may be lying on the bottom of boiler, and the boiler
surround by water.
