PETER O. ROTH, OF NEW YORK, N. Y.

BOILER AND HEATER.

Appiication filed July 21,

T all whom it may concern.

Be it known that I, Purim 0. Born, a citizen of the United States, and a resident of the city of New York, Middle Village, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Boilerand Heater, of which the following is a full, clear,and exact description.

This invention relates to steamboilers and heaters and has for an object to provide an improved construction over my prior Patent No. 1,272,113, issued July 9, 1918.

Another object of the inventionis to pro{ vide an improved construction of means for causing the water in the boiler to absorb more of the heat units passing through the flues the arrangement,being adjustable to take care of different conditions of fire, boiler and the like.

A further object of the invention is to provide an improvedarrangement of'spiral sections for boiler tubes together with means for moving them to an aligned position or a spiral position. i i i A still further object of the'in vention is to provide an improved arrangement of battling or deflecting means for boiler tubes together with a system of operating members at the end of the boiler which may opcrate any desired series of bafiies.

An additional object is to provide not only baffling means for boiler tubes but animproved arrangement of air or steam injection therein which will tend to produce a better combustion and a better draught.

Figure 22 isa view similar to Figure2 but showing a modified form of the invention wherein the device is adapted to be used for heating water or superheating steam. I i

Referring to the accompanying drawings by numeral, 1 indicates a furnace .ofcany desired type and 2 a tubular boiler provided with any desired number of heating tubes There is aspace 4 arranged. at the rear of the boiler 2 and a chamber 5 arranged in the-front part of the boiler, said chamber beingusuallv found in 'boilers of this type. The chamber 5 is utilized in accommodating certain pipes. gearings and other parts embodying certain features of the ininto the tubes at different points for increasing the combustion in the tubes and also for increasing the draught. As shown in this figure, the tubes 8 are provided with a batfling structure 6 consisting of a number of independent spiral sections 7 mounted on a suitable tube 8 and freely rotatable thereon. If desired, the tube 8 may be one continuous tube for supporting the section 7 but preferably it is formed in a number of parts connected by tubular connectors 9, each of said connectors having one or more inclined apertures 10 whereby' steam forced into the tubes will be discharged at a number of points in the boiler tube 3, Arranged at one end of each of the tubes 8 is a gear wheel 11 having a plurality of gears or projections 12 designed to straddle the web of the end spiral section 7 as shown in Figure 15 whereby when the gear wheel 11 is rotated, the section 7 will be moved into a spiral formation or into an aligned formation according to the direction of movement of the gear wheel From Figures 15 to 19, it will be observed that the batting member 6 is formed from a large number of spiral sections 7 con structed as shown in Figure 20. Each section is formed with a tubular body 13 adapted to fit over the tube 8 and with a pair of semi-tubular portions 14 and 15, said semi-tubular portions being less than a half tube and arranged to project beyond the tubular portion 13 at each end so as to overlap the ends adjacent the tubular portion 13. By reason of the fact that the portions 14 and 15 are less than a half tube, there is provideda loose motion in a circle so that when the sections 7 are rotated in'one direction, the respective portions 14 and 15 will strike the webs 16 and 17 of the next adjacent sections 7 and cause an alignment of the respective sections as shown in Figure 16. If rotated in the opposite direction, these same portions 14 and 15 will engage on their opposite edges the webs 16 and 17 and cause aspiral formation as shown in Figure 17. On some occasions it may be desirable to have certain of the sections formed in spiral relation as shown in Figure 17 while others are arranged in alignment as shown in Figure 16. In order to accomplish this result. the respective gear wheels 11 are rotated for one or more revolutions and the result will causethe device to appear as shown in Figure 1. It will be noted that the gear 1] and associated parts are at the forward end of the boiler so that when moving the parts to a spiral position, the end of the bafiiing members toward the front of the boiler will be first formed into a spiral;

lVhen the parts are as illustrated in Figure 1, the flame may freely pass through the rear part of the tube 3 but is checked at the front part for permitting the water in the boiler to absorb heat units therefrom. The rear ends of the bathing members are connected with suitable plates 18 as shown in Figure 2 so as to beheld against rotation whereby the various spiral sections 7 may be freely moved until all are arranged in spiral relation or until all are arranged in alignment. The plates 18 may form any suitable or desirable framework to properly act as a fixed holding member. At the front a more elaborate arrangement is provided which consists of a number of metal frames 19, each frame 19 being provided with sections 20 and 21, said sections interlocking for forming a housing for receiv ing the respective gears 11. It will also be noted that the section 20 is provided with a journal box 22 which supports the tube 8. Each of the sections 21 is provided with a chamfered corner 23 and a lug 24 at the corner. If desired, a similar structure may be provided in section 20 so as to accommodate the respective washers 25 and suitable bolts 26 whereby the various frames 19 are secured together in a nested formation as shownin Figure 7. hen nested in this manner the boxes 22 are in a line with the center of tubes 3 s0 as to properly support said tubes and permit a free rotation of the spiral member 7 arranged loosely thereon. It will be noted that by this construction a built-up spiral or framework is produced which encloses the respective gear wheels 11 but permits any one gear wheel to be removed at any time together with its Operation of spiral member 7 and other parts without disturbing the remaining gear wheels or other members. All of the frames 19 are of the same size except those at the periphery which are bolted by the bolts 26 to the flange 27. These frames are merely cut off sufficiently to produce a proper fit.

while the remaining frames are of the same size and shape and all of the gear wheels 11, are also the same size and intermesh. This will naturally cause a reverse rotation of certain of the gears in respect to the plates. It will, of course, be necessary to make the adjacent spiral members 7 operate in reverse direct-ions so that all of the spiral members may be thrown into a spiral or removed from a spiral simultaneously. As all of the gears 11 are in mesh, they may be driven by a single power gear 28 secured to a stubshaft 29;carrying1a-bevel gear 30.. This bevel gear is supported by a, suitable.

bracket .31 bolted or otherwise secured to one of the .frames 19 and the bevel-gear 3O ,meshes with a driving .gear32 secured to shaft 33. p This shaft vextends joutwardly through a box 34. and is provided. with a hand wheel 35.whereby the various gears 11 s)iral members .7 and associatedimembers maybe properly. actuated .at anytime. A notched wheel-.36 isrigidlysecured to the. shaft 33 andco-acts with ainanually actu ated and pivotally mounted catch her 37,- pivotally connected with the box 34.

When it is desired to rotate the shaft 33,

the catch .bar 37 is raised and. the shaft .ro-q tatedto the desired extent. Thelever 37 is. then moved downwardly into one of the notches of .member 36.,and; thereby l ocks ;all of the parts against accidental movea ment. In order. to permitthe operator to know the exact condition of the respective spiral members '1 a dial 38 isrprovided on box 34 over which the pointer 39 moves.

. The dial is calibrated to show the exact position of thespiral nembers 7 according to the position of the pointer 39. r The pointer 39 is rigidly secured to a shaft 40, which shaft. is keyed or otherwise secured to a ,gear wheel 41 meshing with a pinion 42 loosely mountedon the shaft 33 but n'gidly secured to a gear wheel :43 meshing with pinion 44 loosely. mounted on shaft tO', The pinion 44-, is rigidly secured to agear wheel 45:,meshing with a pinion .46, said pinion 46. being keyed or. otherwise rigidly con: nected with shaft 33.

will cause the pointer 39 to move inproportion to the movementof thespiral. members7.

In 1*iguresl, 2 and 14 will be seen, what maybe termed, an 'ejecting mechanism for steam .co-acting with thespiral member 7 and the tube 8. A mixture of ag'certaiir quantityof steam with the .gases i n the tube. 3 has been found to be beneficial in respect to producing a better chemical union; and, consequently, a bettercombustion 01", the

: gases. In addition. the use of jets of steam; inthe tubes 3 w ll increase the draught. In.

forming a structure for carrying out these purposes, the tubes 8 are utilized not onlyas a support forthe spiral section 7 but ha s y a passage-way for, the steam. These tubes are divided into sections by connecting? sleeves 9, 'each sleeve'having a series ofuap-' ertures 10 extending in such a direction that the et of steam willbe discharged toward the discharge end of the respective tubes In the .tubes 8, a stationai'y1block 47 mav be provided. as shown in Figure 2 or a slid-1 ing block 48. If desired, both of these (lividing members may be used. in. thesame boiler.

at the same time. These dividing members In this. way a re? ducing train of gears lSJQIOVldBd wh ch are providediso thatsteain may be admitted y at either end or at both ends and even dis tributedto theopenings .101 A distributing 110x49 is connected'with each tube Swat each endand a header connected to-each series of boxes 49.-.'The respective headers w are connected to a suitable single source of steam supply. In each lot theboxes 49a 3 through the various apertures 10.0f the varioussleeves Incasethe sliding. block 48 is used the pressure of the steam in the res pective boxes 49 ateach end is the same and,

consequently, the block 48 will automati cally positionitselfinflthe center and allow thesai ie to be distributed as if it were .fixed.

lVhe'retliestationary block47 is used, steam.

must be. admitted at bothends in order to a use all of thesleeves Qwhereas ifthe slide ingJblock 4-8 is used, steammay be admitted at both ends or at either'end. When admitted at one: end,. block 48v is forced to the opposite end and steam is thereby permitted. to easily pass out the apertures 10 in all of.

the sleeves 9. It is, ofcourse, evident that suitable valves may be provided asshown in Figure, 14 :or. other means .ofcontrol may be provided for the steam. :Inadditionnto the uselor" steam for-the purpose specified orior any other purpose, air 'may be used which iswusually moreetfective in cleaning out soot from. the tubes than'steam. Ifdesired,

steam can be turned-off-from the pipes 50 andzairr-turned on whenever it is desired to clean the tubes'fromsootand after the cleaning operation; if steam is desired, the

air'could be turned offend steam admitted. though the use-of a ce'i'tai'n quantity of air inthe tubes will. produce desirable result-s with certain kinds of fuel. ItwiS. therefore,

evident that either steam or air may be freely used-for:either cleaning or assisting thencombustion or assisting the draught.

.In Figure 21 will be seen a slight modified tormt of spiral member wherein the shoulders 14 and 14" extend from. the same end of thetubular-body.-

Referring to Figure 22, it will be seen that the tubular connectingmembers 9' are solid instead of perforated as in the preferred form. eIn this form of the invention a pipe is, connected to a suitable source of'steams'upplyand the steam is allowed to pass into the .tube- 8 .andirom" thence through the opposite header and out the discharge pipe 53 where it" may be usedas superheated steam. l If desired, this arrange" 'ment could be provided for any or all of the flues though ordinarily it is used only with the upper flues. This will permitthe tubes 8 in the lower fines to be used as water heaters.

When used as water heaters the water is passed in through the pipe 54 to the header at one end of theboiler and from thence through the lower tube '8' to the header at the opposite end and from thence out the discharge pipe 55 to any suitable point. As the bottom-of the boiler is cooler than the upper part, the tubes in the lower flues are preferably used for heating-water while the upper tubes are preferably used for superheatingsteam though if desired all of the tubes could be utilized for either purpose by a proper connection of thetubes,

What I claim is 1. In a. device of the character described, the combination with a boiler haxing fines, of means for retarding the passage of the flame and the products of combustion through said flues, said means comprising a centralsupporting member extending longi-b tudinally through each of sa'idflues, a plurality of sleeves rotatably mounted on said supporting member and provided with spiral formed webs, each of said sleeves having an overhanging section for transmitting rotary motion to the next adjacent section, and means forrotating the end sleeve in each of the flues. i f
