Improvements in Steam Boilers.
1, JOHN PARTINGTON, Boilermaker, of Water Lane Boiler Works, Thornton
Road, Bradford, in the County of York, 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:-
In my improved boiler I form a long water box, or chamber, ruuning horizontally
the width of the boiler, this chamber being suitably stayed, and placed at a suitable
distance above the front of the firegrate; and I have a corresponding chamber at
the back of the boiler, the latter being lower than the front chamber, and both the
front and back boxes or chambers having suitable covers or doors.
I can place a series of such chambers one above the other, the bottom box having
an opening running the length of the top of the box, or it may have a number of
smaller openings; and the next box or water chamber, having an opening both top
and bottom running its entire length, or having a number of openings, to correspond
with the openings in the next chambers.
These boxes or water chambers, are bolted or riveted together, and any number
may be placed one above the other, the opening or openings leaving a free com-
munication between each. The top box, or chamber, would have an opening
running horizontally at the bottom, or is furnished with openings to correspond with
the chamber below it; and at its top there would be one, two, or more branches,
leading into a steam chest or chests; a branch or branches leading from the top
back box to the steam chamber or chambers in the same manner.
any
The front and back boxes are coupled together by water tubes of suitable
size, leading from one to the other and screwed, flanged, or expanded to the boxes
or chambers, the tubes sloping down from the front to the back chambers, and so
joining the two together.
Where a series of such boxes are used, I can furnish them with tubes of different
sizes, the bottom tubes being the largest, and the top the smallest, so that the
amount of heating surface may be increased, the firegrate being placed underneath
the bottom tubes, and the fire and heat rising up amongst the tubes.
Instead of placing the water chambers or boxes horizontally, I can place them
vertically, side by side, opening into each other at their sides, and bolted or riveted
together, in a similar manner to the horizontal chambers, the steam chest or chests
being coupled to the top of the water chambers.
I can place underneath the boiler such as described above, two front boxes or
legs, for water, taking the place of brickwork, these being riveted or bolted at each
end to the bottom front horizontal or vertical water box or chamber, with an opening
into same; and at the back there are corresponding legs riveted or bolted at each
end to the back horizontal or vertical water box. In between these back legs at
the bottom there is a mud drum, or tube, riveted or bolted, with a series of tubes
running along the top into the horizontal or vertical chamber or chambers above.
The front and back legs, or water boxes, are coupled together by tubes, thus
forming the sides of the furnace; and at the bottom of the legs or water boxes,
there is a tube or tubes coupled to the front and back, so as to allow of any sediment
being drawn off from the front legs.
For getting rid of the soot that may collect round the tubes, I have a steam jet
suitably placed for clearing them.
The series of water boxes may be encased with iron or with masonry.
In the drawings annexed hereto Fig. 1. shows the side view of my improved
boiler arranged with nests of tubes one above the other. A. is the bottom front

tubes coupling the two chambers together. D. D. D. D. are water boxes or
chambers placed horizontally one above the other, E. E. E. E. are the openings

chamber B. The lids or covers of the front and back water chambers or boxes
are shown L. M. is the furnace the heat passing amongst the tubes C.

back and front and tubes forming the sides of the furnace and also shows the
position of the mud drum; Fig. 4 being a back view, looking from the front of the
same arrangement. N. is the front water leg or box placed on each side as shown
in Fig. 4. N. N. O. is the back water leg or box and P. is the mud drum shown
in section in Fig. 3. and across the back in Fig. 4. This mud drum connects the
two back water legs or boxes together. A is the front water chamber riveted or
bolted to the top of the water leg N. with the opening E. for communicating
between the two chambers N. and A. B is the back water box which is connected
to the two back water legs O. with tubes Q placed at suitable distances running
along the top of the mud drum P. as shown in Fig. 4. R is a bottom tube con-
necting the front water leg or chamber N. to the mud drum P. S. are tubes
forming the sides of the furnace and connecting the front and back water legs or
chambers N. and O.
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 :-
1. The improved steam boiler substantially as described and shown in drawings.
2. In steam boilers the use of a long horizontal water box or chamber, or boxes
or chambers, having an opening or openings in the top, or in the top and underside,
substantially as described and shown in drawings.
3. In steam boilers the use of a long vertical water chamber or chambers
having an opening or openings in the sides or side substantially as described.
4. In steam boilers the use in series of long horizontal water boxes or chambers
having an opening or openings in their tops and undersides, such series of water
boxes or chambers being riveted or bolted together leaving an opening or openings
from one to the other substantially as described and shown in drawings.
5. In steam boilers the use in series of long vertical water boxes or chambers
having an opening or openings in their sides or side, such series of water boxes or
chambers being riveted or bolted together leaving an opening from one to the other
substantially as described.
6. In steam boilers the use of nests of tubes of varying sizes, one above the
other, the bottom tubes being the largest and the top tubes the smallest so that
the area of heating surface may be increased substantially as described and shown
in drawings.
7. In steam boilers the use of water legs, or chambers for water forming legs,
such legs being coupled together by horizontal tubes forming the sides of the
furnace substantially as described and shown in drawings.
8. In steam boilers the use of a mud drum or chamber running at the bottom
and in between two chambers at the back forming legs containing water, with or

page_text: without tubes running along its top into the back water chamber substantially as
described and shown in drawings.
9. In steam boilers the use of a tube coupling the bottom of the front water leg
or water chamber forming leg to the back water leg substantially as described and
shown in drawings.
