County of York, for the Invention of "IMPROVEMENTS IN BOILERS FOR
Sealed the 31st March 1876, and dated the 9th October 1875.
PROVISIONAL SPECIFICATION left by the said John Hartley and
Zaccheus Sugden at the Office of the Commissioners of Patents,
with their Petition, on the 9th October 1875.
We, JOHN HARTLEY and ZACCHEUS SUGDEN, Welded Boiler Makers,
of the Atlas and Premier Works, Halifax, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
BOILERS FOR HEATING WATER FOR WARMING BUILDINGS," to be as follows, that
io to cov

page_text: and through the chamber flues, giving easy access for feeding. The
feed places are made with top feeders fitted in the brickwork and fixed
to openings made through the chamber flues. These openings are
jacketted and connected to the water spaces in the tops of the boilers
forming chambers for the circulation of the water and giving heating
surfaces. Covers are fitted on the top feeders, and the ordinary plan of
feeding through the fronts may be used. The top feed places allow
the banking up of the fuel, so that it may be left for a lengthened period
without attention.
Secondly. Constructing saddle boilers in a similar manner as herein-
before described, with the chamber flues recessed, allowing the flames,
heat, and gases to return without coming to the front, preventing
damage to the brickwork by the action of the flames, heat, and gases.
Thirdly. Constructing saddle boilers with jacketted top feed places
and recessed chamber flues; also with front water ways.
Fourthly. Constructing oval, oblong, and square boilers with down
draft flue formed in the boiler, the opening from the fire chamber to the
down draft flue being formed under the top water space. The top of the
boiler is fitted with a feed place formed with a top feeder fitted in the
brickwork, and fixed to an opening made in the top water space, and
fitted with a cover. The boiler is fitted with midfeathers to allow the
flames, heat, and gases travelling through the boiler sides to act round
and partly round the side surfaces of the outside plates. The smoke
flue and regulating damper are made with a cylindrical tube having an
opening forming a tap, and working in another cylindrical tube. The
tap is made with closed end in front, having a handle to turn the tap to
regulate the draft by giving more or less opening. For cleansing the
flue the tap has only to be taken out, doing away with cleansing
doors.

TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOHN
HARTLEY and ZACCHEUS SUGDEN, Welded Boiler Makers, of the Atlas
and Premier Works, Halifax, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of October, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Hartley and Zaccheus
Sugden, Her special licence that we, the said John Hartley, and
Zaccheus Sugden, our executors, administrators, and assigns, or such
others as we, the said John Hartley and Zaccheus Sugden, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, usc, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN BOILERS FOR
HEATING WATER FOR WARMING BUILDINGS," upon the condition (amongst
others) that we, the said John Hartley and Zaccheus Sugden, our
executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Hartley and Zaccheus
Sugden, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the Drawing hereto annexed, and to the figures and letters marked
thereon, that is to say :-

page_text: setting; Figure 6, sectional clevation; Figure 7, side view with mid-
feather; and Figure 8, longitudinal section of the same.
Figure 9 represents a side elevation of a saddle boiler with back water-
way, chambered return flue front, waterway, and top feed place; Figure
10, sectional elevation; Figure 11, elevation shewing midfeather; and
Figure 12, longitudinal sectional elevation of the same.
Figure 13 represents a longitudinal section of a saddie boiler with
recessed chamber flue, back waterway, and jacketed top feed place;
Figure 14, longitudinal elevation of the same.
Figure 15 represents a longitudinal section of a saddle boiler with
recessed chamber flue, front waterway, and jacketed feed place; Figure 16,
side elevation of the same.
Figure 17 represents a plan of an oval saddle boiler with down draft
flue; Figure 18, longitudinal section with down draft flue and top feed
place; Figure 19, elevation with setting; and Figure 20, clevation of
the same.
Figure 21 represents a sectional elevation of an independent saddle
boiler with down draft fluc and top feed place; Figure 22, plan;
Figure 23, front elevation; and Figure 24, back elevation of the same.
Similar letters of reference are used in all the Figures to represent
similar or corresponding parts.
Firstly. In Figures 1, 2, 3, and 4, A shews saddle boilers con-
In
structed with top feed places for supplying the furnaces with fuel.
the crown of the boiler is formed an opening, in which is fitted a tube B,
on which is fixed a top feeder C, which is fitted in the brickwork D; the
top feeder C is for the purpose of putting in the fuel, which falls on the
horizontal bars E, giving an easy access for feeding instead of feeding
through the fire-place F; but the ordinary method of feeding through
the front may be employed. The top feed place allows of banking up
the fuel, so that it may be left for a lengthened period without attention.
A cover G is fitted on the top of the top feeder C.
Secondly. A, Figures 5, 6, 7, and 8, shew saddle boilers constructed
with chamber flues I; the boilers are made with top feeders C, as
herein-before described, but the tube B is jacketed at H and connected

page_text: to the water spaces forming chambers for the circulation of the water.
The top feed place allows of banking up the fuel J.
Thirdly. A, Figures 9, 10, 11, and 12, shew saddle boilers constructed
with back and front waterway and return fluc, and jacketed top feed
places as herein-before described. In Figures 13 and 14 the saddle
boilers are constructed with back waterway, return chambered flue
recessed with top feed, jacketed as herein-before described. Figures 15
and 16 shew a boiler similar to that shewn in Figures 13 and 14, with
the addition of waterway front K.
Fourthly. Oval, oblong, and square boilers are shown at A, Figures 17,
18, 19, and 20, constructed with down draft flues L formed in the boiler,
and having the opening M from the fire chamber to the down draft
flue L formed under the top water space N. The tops of the boilers are
fitted with top feed places formed with top fecders fitted in the brick-
work, and fixed to openings made in the top water spaces, and fitted
with covers as herein-before described. The boilers are fitted with mid-
feathers O, allowing the flames, heat, and gases travelling over the
boiler sides to act round and partly round the side surfaces of the out-
side plates.
Fifthly. Independent, oval, oblong, and square boilers are shewn at A,
Figures 21, 22, 23, and 24, constructed with down draft flues L formed in
the boilers and having the opening M, from the fire chamber to the down
draft flue L, formed under the top water space N. The tops of the
boilers are fitted with feed places formed with top feeders as herein-
before described, but without midfeathers, and are fitted on stands P;
these boilers require no brickwork.
Having thus described our improvements and the best means we are
acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shown
and described, as these may be varied without departing from the
peculiar character of the Invention, but what we do claim is,―
Firstly. The construction of saddle and other boilers for heating water
for warming buildings, with top feeders, substantially as herein described
and represented in the accompanying Drawing.
Secondly. The arrangement and construction of oval, oblong, and
square boilers; also of oval, oblong, and square independent boilers

page_text: with down draft flues formed in the boilers and fitted with top feeders,
substantially as herein described and represented in the accompanying
Drawing.
In witness whereof, we, the said John Hartley and Zaccheus
Sugden, have hereto set our hands and seals, this Seventh day
of April, in the year of our Lord One thousand eight hundred
and seventy-six
