STEAM OR HOT-WATER, BOILER.

SPECIFICATION forming part of Letters Patent No. 580,864, dated April 13, 1897. Application filed July 18,1896. Serial No. 599,658. (No model.)

T0 at whom it may concern:

Be it known that I, JOSEPH J. BLAOKMORE, a citizen of the United States, residing at J ersey C-ity, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Steam or Hotater Boilers,

,fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

"his invention relates to a boiler co1nprising a series of flat vertical sections each having flue-passages through the upper part and water-legs, with firebox and ash-box between the same, and the lower ends of the waterlegs connected by a horizontal water-bar forming the bottom of the ash-box.

The top of the section and the horizontal water -bar are each provided with an upwardly-projecting chamber having upon its opposite faces coupling-sockets adapted to receive a suitable coupling to form continuous passages through the series of sections, which series are drawn together by bolts extended outside of the waterway and fittedto lugs upon the front and rear sections.

The body of the section above the fire-box is made of less thickness than the edges of the sections to permit the heated gases to circulate between the adjacent faces of the sections, and the margin of each section is preferably provided with a projecting rib to expose the edge portions of the sections also to the action of the gases.

The flue-passages are preferably formed as vertical slots through the body ofv the section, and such flue passages are divided transversely, as well as the adjacent space be tween the bodies of the sections, to form direct and return flues.

A deflecting-plate, inclined upwardly from the middle toward the ends, is preferably formed within the top of the section below the coupling-sockets to direct the rising fluid to the sides of the section before it is discharged therefrom.

These improvements, with other details of construction, are shown in the annexed drawings, in which- Figure 1 1s a perspective elevation of the Fig. 2 is a side elevation of the same. line 3 3 in Fig. 2. line 4 tin Fig. 2

boiler. Fig. 3 is a cross-section on Fig. .4. is a cross-section on with a single section of rocking grate exhibited. Fig. 5 is a front elevation of the boiler with the front plate removed and one-half of the section shown cut open where hatched, and Fig. 6 is avertical sectional view taken partly on line 6 6 in Fig. 5 and partly where marked 7 in the margin of Fig. 6 upon the line 6 7 in Fig. 5. The two section-planes intersect the bottom of the ash-box at different points, the view on line 6 6 showing the rectangular shape of the water-bar, while the view on line 6 7 shows the interior of the water-chamber which is formed at the middle of such bar, with the couplings which are fitted to the adjacent faces.

A designates the body of the section; 13, the water-legs, extended downward past the fire-boX C and ash-box. D, between which a grate E of any suitable character is supported.

F is a horizontal water-bar connecting the lower parts of the water-legs; G, a waterchamber projected from the upper side of the same at the middle, and H a lug uponthe top of the same through which bolt I is extended. Asimilar water-chamber G is projected from the top of the section at the middle, and bolting-lugs H are formed at opposite sides of the same upon the end sections to receive tiebolts 1. The bolts 1 and I serve to clamp all the sections together when in use without passing through or obstructing the waterway.

The water-chambers G and G are provided upon opposite faces, respectively, with coupling-sockets g g, which are shown formed with conical ground-seats to receive groundjoint nipples f, (shown in Fig. 6,) which form continuous passages common to all the sections at the top and bottom of the boiler. Pipes h and h are connected, respectively, withthe chambers G and G to lead the-fluid into and from the boiler.

Vertical slots are extended through the section and divided near the middle of their length by horizontal water-bars J, forming an upper and lower series of flue-passages K K.

The body of the section containing such flue-passages is of less thickness than the top of the section and the edge portions of the same, and such edge portions are also made of less thickness than the water-bar F and the water-leg below the level of the grate.

To make the entire margin of the section legs receives the return of the same thickness and the bottom of the water-leg, a rib L is formed above the grate upon both faces of the section at the margin, and such ribs are drawn in contact when the sections are mounted together, as shown in Fig. 1, which affords the heated gases access to the adjacent faces of the sect-ions at all points above the grate. A deflecting-plate Q is shown in Fig. 5 within the section between the tops of the flue-passages and the coupling-sockets g, which, when the boiler is used for generating steam, is employed to separate the steam from the water and to prevent the water from boiling over. The plate Q is preferably inclined upward from the middle toward each end.

The adjacent faces of the sections upon a level with the bars J are provided with horizontal cleats J to support partition-plates a, which operate in connection with the bars J to intercept the rising gases and hold them longer in contact with the lateral faces of the sections. One of the partitions (t is broken in Fig. 3 to clearly exhibit the cleats J.

A front plate M is secured upon the front end of the sections and provided with fueldoor an opposite the fire-box and a box or cleaning-door M, which is adapted to cover the front ends of the flue-passages K and K and to form a return-flue box for the same.

A back plate N is secured upon the rear end of the sections and provided with a sm okebox 0, having a smoke-outlet P.

The smoke-box covers the rear ends of the flue-passages K K and is provided with a damper 0, adapted to close the lower passages K.

The partition-plates a are supported removably by the cleats J, and where the draft supplied to the boiler is good such plates may be applied, as shown in Fig. 6, to out off the direct access of the gases from all the upper flue-passages K.

With the damper closed, as indicated by dotted lines 0 in Fig. 6, the gases which are intercepted by the partition plates a are thrown forwardly through the passages K into the return-flue box N and thence into the upper flue-passages K, from which they pass freely into the smoke-box. The partitions a may be removed from the ribs J by turning them up edgewise, as shown at a in Fig. 6, and then dropping them down into the fire-box, and where the draft is defective the partitions may be removed between the sections nearest to the return-flue box M, thus affording the gases a shorter circuit to the smoke-box.

It will be understood that the capacity of the boiler may be varied by employing a suitable number of the vertical sections, and the adaptation of the partitions a for removal adapts the furnace, whatever its size, to be suitably arranged for operating with the draft that maybe available. The horizontal waterbar which connects the bottom of the waterfluid from the heating-radiators through the pipe h and distributes it effectively to every portion of the boiler, the heat around the ash-box being fully utilized in warming the water before it enters the body of the section. The horizontal form of the water-bars adapts them to form a flat bottom for the ash-box, and the Water-chambers G and tie-bolt I, arranged along the middle line of the bottom, are so disposed as not to interfere with the removal of the ashes. The sections are of such nature that special castings are not required for the front or rear section of the boiler, as in some constructions, and the patterns required to make the castings for a boiler are thereby considerably cheapened.

The labor required to fit up and connect the several sections is exceedingly small, while the introduction of the heated gases to the entire adjacentfaces of the sections and the circulation of such gases forward and back ward through the flue-passages K K secure a high degree of efficiency with a minimum of cost.

Vhere the boiler is used for making steam,

the deflecting-plate Q serves a very useful purpose to prevent water from boiling up into the pipes h, but where the boiler is used for heating water only the deflecting-plate is omitted from the section, as it would seriously obstruct the free passage of the water to the pipes 71..

I am aware that it is common to connect fittings by means of slip-nipples, and that it is also common to make that portion of the section through which the smoke-fines are formed of less thickness than the edges of the section. My sections differ from previous constructions in having two sets of flue-passages above the fire-arch, (which extends transversely between the water-legs above the fire-box,) with means, as the horizontal partition-plates a, to confine the gases to the lower passages in their forward movement. By this construction all the sections in the boiler may be made from the same pattern and the partition-plates may be made to produce a direct and return movement of the gases, as indicated by the arrows in Fig. 6.

I am aware that horizontal water-bars have been used. over the fire-box to form the crown of the fire-box and absorb the radiant heat, but I am not aware that the bottom of the ash-box has ever been formed of horizontal Water-bars connecting the lower ends of the water-legs, such water-legs being extended below the level of the grate for that purpose. By this construction, and especially where the return water-pipe h is connected with the middle of the horizontal bars F, the fluid is distributed most effectively to every portion of the boiler and the heat radiated toward the sides and bottom of the ash-box fully utilized in warming the water before it enters the body of the section.
