Application filed January 28,1906. Serial No- 297,483.
To all whom it may concern.-
Be it known that I, RICHARD WATSON MEwEs, a subject of the King of Great Britain, residing at That Cheer, in the county of Keokuk and State of Iowa, have invented new and useful Improvements in Boilers, of which the following is a specification.
This invention relates to steam and water heating boilers; and the object of the same is to provide a boiler, preferably of the vertical type, which will arrest and convey to the water the greatest amount of heat from. the products of combustion and economize in the use of fuel with material expedition in heating the water.
The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.
In the drawings, Figure 1 is a sectional view showing a steam-boiler embodying the features of the invention. Fig. 2 is an elevation of the steam-boiler broken away and shown partially in section. Fig. 3 is a sectional view of the improved boiler arranged for hot water. Fig. 4 is an elevation of the boiler shown by Fig. 3. Fig. 5 is a horizontal section on the line 5 5, Fig. 1, shown broken away'in part and portions illustrated in dotted lines. Fig. 6 is a horizontal section on the line 6 6, Fig. 1, to particularly illustrate the grate and showing parts of the operating mechanism in dotted lines.
Similar numerals of reference are employed to indicate corresponding parts in the several views.
The numeral 1 designates the body of the boiler, having a double wall to form an annular Water-space 2, surrounding a fuelchamber 3, in which. the fire-bed is located. The lower portion of the body 1 is suitably connected to a hollow base-support 4, providing an ash-receiving means, a plurality of openings 5 being formed in any suitable manner between the base-support and the lower end of the body 1., either produced by the use of grate-bars of suitable construction or by the formation of openings at intervals in the connected parts. At the center of the lower extremity of the body 1 and the upper extremity of the base an enlarged opening 6 is provided, through which a conical grate member 7 projects, said grate member being perforated or otherwise formed open, as at 8. This grate member will have imparted thereto a reciprocating rotation in a horizontal upper ends the circulating-pipes 12.
plane and also a vertical movement by means which will be more fully hereinafter explained. The upper end or crown 9 of the body 1 projects over the fuel-chamber 3 and is also composed of inner and outer walls to form a water-space having greater dimensions than the water-space 2. Disposed over and connected to the crown 9 is a waterchamber 10, having a lower head 11 of such shape as to give the bestresults in producing steam or heating the water in the chamber, said head being preferably of the form shown and also operating as a fire-plate. In
all structures this head or fire-plate 11 will have as much surface as possible exposed to the action of the products of combustion, so as to facilitate the heating of the water inthe chamber 10. The chamber 10 is structurally separate from the body 1 and connected to the latter at intervals by circulating-pipes 12, Fig. 2, connecting the crown 9 and the lower portion of the said chamber 10 at intervals, and, as shown by Figs. 3 and 4, the chamber and body are connected by metallic coupling-straps 13. The center of the crown 9 has an opening 14 formed therein, with chamber 10 and the lower portion of the body 1, said return-pipes displacing at their To the central top portion of the chamber 10 is connected an outlet-pipe 18, which will be used in the hot-water boiler for conveying the hot water from the latter and in the steam-boiler as a means of conveying steam to any point where it is desired to use the same. The hotwater boiler shown by Figs. 3 and 4 will also have a suitable return connection 16.
One-half of the crown 9 is formed with a plurality of openings 19 to serve as a means of communication between the fuel-chamber 3 and what may be termed the combustionchamber 20, formed between they head 11 of Where the boiler is used.
the chamber and the top sheet or wall of the head 9.- These openings 19 are located in that half of the head 9 opposite the point of communication of the smoke pipe or stack 21. In other words, the smoke pipe or stack 21 connects with the combustion-chamber at a point distant from the location of the openings 19, so that the greatest benefit may be derived by an extended circulation of the products of combustion within the chamber 20 and in contact with the head or plate 11. To obtain the most beneficial effect of the products of combustion passing upwardly through the openings 19 with respect to the water contained in the chamber 10, concen-' trators 22 are used and fitted in or made to communicate with the upper portions of the openings 19 and consist of tubes with upper flaring outlet extremities 23, located close to the head or plate 11 of the chamber 10. By this means the highly-heated products of combustion passing upwardly through the bustion-chamber 20 and finally pass out through the smoke pipe or stack 21. These concentrators may be used in connection with any boiler embodying the essential features heretofore explained and consisting of a lower body having an annular water-space around a furnace or fuel-chamber with open ings through the head or crown thereof and a water-chambersuperposed on the head or crown and forming with the latter a combustion-chamber and a smokepipe connected to said combustion-chamber at a point distant from the location of the communicating openings between the fuel-chamber and the combustion-chamber and located in the head or crown of the body of the boiler.
Another improved feature of construction I embodied in both forms of the boiler is a series or plurality of tubular drops 24 depending, from the head or plate 11 close to the point of communication of the smoke pipe or stack 21 with the combustion-chamber 20 and having unretarded communication with the water-chamber 10, but completely closed at their lower extremities. These droptubes depend in the path of the escaping products of combustion and the water therein will be materially heated, with benefit to the general heating operation of the boiler.
It will be understood that as many returnpipes 17 in the form of boiler for producing steam set forth may be used as found necessary or desirable, and, furthermore, it will be understood that communication with the fuel-chamber 3 will be had through the medium of a suitable opening 25, covered by a suitable door.
There are many different methods of connecting the several parts of the boiler thus far described, and it will be understood that the head 11 is constructed as shown to facilitate the production of steam and accommodate the practical application of the returnpipes 17. It is also proposed to protect the walls of the furnace, which might be injured by direct flame-contact, and where there is no water-space, as in Figs. 1 and 2, by an asbestos sheet or inner covering 26. Through this covered wall and communicating with the combustion-chamber are openings 27, normally covered by a slide 28. These openings are used to admit air, when desired, and also for cleaning purposes.
It will be observed from the foregoing that the. boiler is constructed to expose to the flame in the fuel-chamber and the heat of the products of combustion in the combustionchamber the greatest amount of surface possible with which water has contact to facilitate production of steam and heating of the water and minimize the use of fuel and consequently economize in the expense of heating water or producing steam in a boiler for various domestic or other purposes.
The conical grate member 7 has means for imparting thereto a rotary movement in a horizontal plane and also a vertical movement, such means consisting of a shaker-lever 26, projecting through an opening 27 a in the base-sup ort 4. The opening 27 a extends around tfi e base-support 4 a sufficient distance to give the lever 26 sufficient play in its movement in opposite directions, and over the inner portion of the said opening a cover-plate 28 is applied and is held in place by a spring 29 on the lever-26 abutting at its inner extremity against the collar or stop 30, secured to said lever. The conical member 7 is held in movable relation to the grate by a vertical member 31, projecting upwardly through the lower open portion thereof and connected to or forming part of a horizontal crank-arm 32, in radial relation to said member 7 and secured to or forming part of an operating-rod 33, projecting outwardly through the base-support 4 and held in inner and outer bearings 34 and 35, the outer end of the rod 33 being provided with a handle 36 at an angle thereto for operating the same. The rod 33 with its crank 32 practically provides a crank-arm by means of which the grate member 7 may be lowered. and raised for the purpose of assisting in cleaning the grate and permitting clinkers or other obstructing substances to be removed from the grate. It will therefore be observed that the crank-shaft as set forth not only provides means for lowering and raising the grate member 7, but also serves in part as a fulcrum-support.
There are many methods of attaching the several parts, including the concentrators 22, other than those particularly specified, and especially at points where tight jointsare necessary, and it is intended to adopt all means that may be applicable in the jointure of the parts of the boiler structure.
In some of the boiler constructions it is proposed to dispense with the central water tube or uptake 15 and substitute therefor flow-pipes having an increased capacity and of a suitable number to arrive at the result sought. This change will be adopted in water-heating boilers; but in steam-boilers it is preferred that said tube 15 be used.
Having thus fully described the invention, what is claimed as new is 1. In a boiler of the class set forth, the combination of a body having a grate and inclosing a fuel-chamber, the upper part of the body being provided with a perforate crown forming a water-holding means, a waterchamber disposed over and above the crown and connected with the latter to permit circulation of water between the crown and chamber, the openings in the crown being at one side of the center of the latter, a smokeescape conduit connected to the boiler between the crown of the body and the waterchamber and at a point distant from the perforations between the crown and chamber, and concentrators secured in the perforations of the crown of the body and having upper enlarged extremites close to the lower side of the water-chamber.
2. In a boiler of the class set forth, the combination of an inclosing body forming a fuel-chamber and having an upper hollow crown to provide a water-receiving means, a water-chamber arranged over the crown and forming a combustion-chamber with said crown, the crown having a portion thereof perforated to establish communication between the fuel-chamber and the combustionchamber, a smoke-escape conduit connected to the combustion-chamber at a point distant from the perforations in the crown of the body, and means connected to the perforations for delivering the products of combustion close to the under side of the waterchamber.
3. In a boiler of the class set forth, the combination of a body inclosing a fuelchamber and having a hollow water-receiving crown with perforations through a portion thereof, a water-chamber disposed over the said crown and having a tubular connection with the latter, a combustion-chamber being formed between the crown of the water-chamber, and the water-chamber having tubular drops extending into the combustionchamber over the imperforate portion of the crown, and a conduit for the escape of the products of combustion connected to the combustion-chamber adjacent to the location of the said drops.
4. In a boiler of the class set forth, the combination of a hollow body inclosing a fuel-chamber and having a crown with perforations extending through a portion thereof, a water-chamber arranged over the crown of the body and embodying a lower plate and forming a combustion-chamber with said body, the water-chamber and body having communicating conduit means and the waterchamber provided with tubular drops extending into the combustion-chamber over the crown at a point distant from the perforations in the latter, a conduit for the escape of the products of combustion connected to the combustion-chamber at a point distant from the perforations, and tubular concentrators fitted in the said perforations and having upper extended open terminals close to the lower plate of the water-chamber.
