PROVISIONAL SPECIFICATION.
An Apparatus to Increase the Circulation of the Water and to
Admit of the Cleaning of Vertical Boilers.
I, JOHN HENRY HECK residing at Glenwood House Eveswell Park, Newport, Mon.,
by profession an Engineer do hereby declare the nature of this invention to be as
follows:-
The fitting of a metal tube or ring, around the inside of vertical boilers, between
the shell & the firebox or furnace, this tube extending from some distance below the
water level to within some distance from the bottom of the boiler, the tube being kept
in place by lugs & bolts or rivets, thus allowing the heated water & steam next the
furnace to ascend without interfering with the descent of the colder water next the
shell of the boiler, holes are cut in the tube or ring in way of the hand or manholes
usually put in the shell of all vertical boilers, so as not to interfere with the scaling
& cleaning of the boilers & this I claim as an important part of my invention, covers
can be fitted over the holes in the tube or ring, these covers can be removed when
the boiler is not at work & the boiler can thus be cleaned without the removal of the
tube or ring.

An Apparatus to Increase the Circulation of the Water and to
Admit of the Cleaning of Vertical Boilers.
1, JOHN HENRY HECK, Engineer of Glenwood House Eveswell Park Newport,
Mon. 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 :-
The fitting of a tube or cylinder E around the inside of all vertical boilers,
between the shell & the firebox or furnace, the said tube or cylinder extending
from some distance below the water level to within some distance from the bottom
of the boiler, the said tube or cylinder being kept in position by bolted or riveted
lugs, B. so as to divide the space between the sides of the firebox or furnace and
the sides of the shell, into two annular spaces, thereby enabling the heated water
and steam next the firebox or furnace to ascend without interfering with the descent
of the colder current of water next the shell of the boiler, holes are cut in the said
tube or cylinder, in way of all manholes in the shell of the boiler or in way of
the cross tubes in the firebox or furnace, so as not to interfere with the scaling or.
cleaning of the firebox or boiler, a bevilled or square angle ring or plate A. is bolted
or riveted to the upper end of the said tube or cylinder, nearest the water level, in
order to stiffen the end of the said tube or cylinder and to check any excessive
upward movement of the water contained between the firebox of furnace side and
the inner part of the said tube or cylinder when the boiler or firebox is heavily
fired.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. The fitting of a tube or cylinder E around the inside of all vertical boilers,
between the shell and the firebox or furnace, so as to divide the space between the

page_text: sides of the firebox or furnace and the sides of the shell into two annular spaces,
thereby increasing the circulation of the water in the boiler, through assisting the
warmer & cooler currents of water and steam respectively to ascend and descend.
2nd. The fitting or perforation of holes in the said tube or cylinder in way of the
manholes or hand holes in the shell or of the hand holes opposite the cross tubes
of the firebox or furnace, so that the firebox with its cross-tubes can be properly
scaled or cleaned.
3rd. The fitting of a bevilled or square angle covering plate A A. to the end of the
said tube or cylinder, nearest the water level, so as to stiffen the end of the said tube
or cylinder and to check any excessive upward movement of the water contained
between the firebox or furnace side and the inner part of the said tube or
cylinder E.
