Application tiled June 24, 1895. Serial 110.553,84. (No model.)

To @ZZ whom it may concern.-

Be it known that L'Lnwis S. DANIELs, of Utica, in the county of Oneida and State of New Yo1-k,l1ave invented certain new and useful Improvements in Heaters; and l do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the saine, refer ence being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which forni part of this specification.

My invention relates to improvements in heaters.

Fig. 10 shows the rea-r section. Fig. 11 shows the front section of a inodied forni of construction froin the outer side of the section. Fig. 12 shows a vertical section of the heater of the modified forni of construction in which the section of Fig. 11 is employed. Fig. 13 shows a horizontal section of the modified form of construction, taken on line G H of Fig. 12. Fig. 1l shows a horizontal section of the inodied forni of construction, taken on line K H of Fig. 12.

The heater,` as shown in Figs. 1 to 10, inelusive, consists of a Water-front A and a waterback B with a special front section O and any desired number of regular intermediate seetions The front section is provided with a feed-door opening 1 closed by a door 2, and a base-opening 3 closed by an ashpit front 4, and suitable clean-out openings 5 and G closed by doors or covers 7 and 8 respectively. The back B' is provided With a pair oi openings S) and 10, which furnish passage-Ways into the smoke-box 11 secured on the outer side of the 5 5 back B. The intermediate sections E' are provided with a series of upper openings e e? e3 e4 and a series of lower openings at', x2, c3 and x4, which When the sections are arranged in the heater side by side forni a series of iiues 6o extending from front to rear of the heater. In order to furnish sufficient area of iiues and provide for the circulation of the Water, the upper portions of the sections are extended transversely, so that they overhang at the sides, as shown at 'm on, the vertical Water-legs n n of the regula-r sections. This also aids in keeping the height of the heater as a whole down to the minimum, and the heater may be extended or overhung at the sides to a much 7o greater extent than shown in the drawings if desired.

The front section C of the heater is provided upon either side with a large opening c, which corresponds in position to the iiues or openings e e2, the., of the regular sections of the heater, and the space between the Water-legs of the front section is extended above the tubes which form the lower face of the crown of the regular heater-sections, 8o thereby affording a space in which the products of combustion are enabled to turn When arising from the fire and enter the ilues az 0:2, die., of the regular or intermediate sections. The front section C is also provided with a 8 5 short curved tube c2, which spans the corner between'the Water-leg of the section and the crown of the saine, forming a circulation in the Water-leg and increasing the area of heating-surface. The Water-legs and body of the 9o front section correspond in outside outline with that of the intermediate sections and overhang the Water-legs at the upper end in the saine manner. The rear section D (shown in side elevation in Fig. 10) is made of the 95 saine Width and depth correspondin g to that of the regular sections; but it is provided with openings Zand d2 inlieu of the openings of the regular sections. The openings d2 correspond in position to the openings roo at', .602, Q33, co4, e3, and e4 of the regular section and the opening d corresponds in position with the openings e' and c2 of the regular sect-ion. The arm portions di of the openings (Z2 of the rear section correspond also in position with the openings 10 in the waterback through into the smoke-box 11, and the openings d correspond in position with the openings 9 through the water-back into the smoke-box 11.

The cross-tube y, which divides the series of openings c2 @2, tbc., from the series of openings zr 5r?, dsc., is preferably doubly made inclined, as shown, to correspond with the crown-tube y, and is made comparatively wide on its face sides, as shown, so that when several sections are mounted together packing can be inserted between the tubes y of the several sections and prevent the products of combustion passing or crossing the tubes y. The same provision is also made in the vertical tubes y, while the other tubes, as y2, which separate some of the ues, have sharp edges, as shown, which may perhaps allow a small portion of gases to pass between the lues, this not being detrimental to the efficacy of the heater. These tubes only form additional heating-surface. All the tubes y, ly, and Al 2 are made oval in cross-section, as readily appears from the horizontal sections, particularly Fig. 8.

The grate G preferably consists of rocking grate-bars mounted in the front and back and dividing the base portion of the sections into a combustion-chamber, portion l1', and

an ash-pit base portion K'.

The water-legs of the several sections, including' the intermediate and front and rear sections as well as the water-front and waterback, are connected by short nipples, as 12, with the manifolds 13 extending along either side of the heater at the base. The top of each section and water-front and water-back are provided on the center of the section with a semicircular or oval enlargement 14, which provides for a side opening in which engages a nipple 15, which connects each section and the front and back with the steam drum or header 1G, from which the distributing-pipes extend to the several portions of the building to be heated. The enlargement la provides for the ready separation of the steam from the water when used as a steam-heater, and facilitates the circulation of the water when used as a hot-water heater.

By the arrangement of the side connection from the enlargement 14 on the top of the sections of the heater the height of the heater, including the drum or header, is reduced without interfering with the circulation in the sections and heater as a whole.

The crown-sheet flues g/ of the intermediate and rear sections are provided with a V- shaped (on cross-section) lower surface which drops into the combustion-chamber, affording a greater area of heating-surface and providing for expansion and contraction of the tubes, and the arms of the V are preferably curved, as shown in Fig. 6.

There is shown at 17 a damper, which is mounted on a horizontal shaft or spindle 1S extending transversely across the smoke-box 11, which damper is adapted to close openings 10 through the water-back B.

The operation of the heater is substantially as follows: A fire being located on the grate G, the products of combustion arising therefrom circulate in and occupy the combustionchamber l-I, where they are commingled with a fresh supply of air admitted through the door 2 above the grate G, and passing to the front and through the opening X, formed in the front section into the lower set of the horizontal flues formed by the openings .r Q02, tbc., to the rear section of the heater. -In case the damper 17 is open in the position shown in dotted lines in Fig. 6, the products of combustion pass directly into the smokebox 11 and thence out the draft-flue connected to the smoke-boX-at 19. This is what l term my direct draft 7 and is preferably used in starting a fresh fire in the heater. 1V hen the heater is in full operation, it is preferably used, however, with the damper 17 closed in the position shown in full lines in Fig. G, in which case when the products of combustion reach the opening d2 in the rear section D they shift to the side and upward into and pass toward the front of the heater through the lines formed by the openings e3 and el of the intermediate sections into the opening marked c' in the front section, where they pass from the outer side of the heater toward the center and back through the iiues formed by the openings c and c2 in the intermediate sections and through the opening marked cl in the rear section, and through the opening marked 9 in the water-back into the smoke-box 11, and out. which makes the full circulation of the products of combustion through the heater. The return-pi pes (marked 20) of the radiator circulating system are connected to the manifolds 13, preferably an equal number upon each side of the heater. The hot water or steam is distributed from the drum 16, and the arrangement of the tubes of the sections is such as to tend to work the hottest water toward the drum 16, while the colder portion of the water in the several sections of the heater is allowed to work back and have a second application to the heated surfaces of the heater before passing on their course through the radiating system connected with the heater.

In the modified form of construction shown in Figs. 11 to 14:, inclusive, the water back and front are dispensed with and the front and rear sections are so constructed as to include the essential elements of the water front and back of the construction, as heretofore described. To this end the front section O of the modified form of construction is provided with a series of substantially semicircular grooves or passage-ways, as indicated at o, which affords a passage-way from the front end of the fire-box chamber into the lower set of fluesy of the regular sections, and the IIO ISO

section O is also provided with large openings 02 in the upper portion of the body of the section, which affords a transverse passage-way between the outer two and the inner two fines of the regular sections of the heater. These openings o2 are covered by doors or covers, as is usual with a furnace or heater front, and there is also provided a series of openings 03, extending from the front side of the front section through the curved passage-ways o', to afford a clean-out for the lower series of the flues in the regular sections. The upper flue may be cleaned through the opening o2. The special rear section I is provided with an L-shaped pocket or recess p', substantially conforming in shape to the opening d2 in the rear section D of the regular construction, as shown in Fig. 10, and which affords a passageway between all the lower sets of fines into the outer two of the upper set of iiues, performing the same oice as the opening d2 of the rear section D of the regular construction. This rear section is also provided with two openings passing through into the smoke-box arranged substantially in the same manner as the openin gs 9 and ll in the water-back. The fines of each half are separated by a vertical water-partition p2 and the circulation of the products of combustion in the modified form of construction are essentially the same as those of the regular construction, the main difference being as before stated that the water front and back are combined with the front section and back section respectively of the main construction.

In the Iirebox portion of the construction of the modified form, and particularly as shown in Fig. l2, the back wall of the iire box is inclined or let in to the inner side of the rear section l?, as shown at p3, reducing the water-space of this section and increasing the coinbustionspace.

That I claim as new, and desire to secure by Letters Patent, is-

l. The combination in a heater of the sections E, having a crowning` body, having up per flue openings e', e2, e3 and et, and lower fine openings fr', co2, :c3V and 0:4, the two legs spanning the fire chamber, a front end section having transverse openings forming a passage between the flue openings, a passage from the fire chamber into the lower fines, and a rear section having an opening forniing a passage from all the lower flues to the outer side upper dues, substantially as set forth.

2. The combination in a heater of a series of sections each having water legs spanning the fire chamber and a crowning body with an upper and lower series of openings, forming longitudinal fines in the heater, a passage from the front of the hre chamber into the lower set of fines, apa-ssage from the rea-r end of the lower set of fines into the outer fines only of the upperset and a transverse passage at the front of the heater from the outer flues to the inner flues of the upper set, substantially as set forth.

3. The combination in a sectional heater of a water front having feed door and clean out openings, a front section having openings forming transverse passages, a series of intermediate sections each having a series of openings forming a series of longitudinal fines, a water back having openings forming transverse passage-ways between part of the longitudinal flues and having a smoke exit passage connecting with other of the longitudinal fines and a smoke box inclosing the smoke passage in the back, substantially as set forth.

fi. The combination in a heater of a series of sections 'each having a protuberance at its top with a large internal area and a side opening of smaller area, a drum lying beside the protuberances of the several sections and connections between the drum and the protuberances of the several sections at the side openings thereof, substantially as set forth.

5. The combination in a sectional heater of a front section having openings affording transverse passages, a series of intermediate sections having a series of openings affording a series of longitudinal iiues, a back section having openings affording transverse passages and a smoke eXit passage, substantially as set forth.

In witness whereof I have affixed my sign ature in presence of two witnesses.
