To all whom t may concern: Y

Be it known that l, CARL ERIK ANDnRstionable elements from being rexpelled fromV the furnace. l y

Another object of this invention is the production of a smoke consumer having a plurality of consuming pipes through which the smoke which leaves the lire-box is adapted to pass and be consumed since the heat of the consuming pipes will be of suficient intensity to burn the carbon or volatile matter of the smoke, allowing only the air and burnt gases to be expelled.

Still another object of this invention is the production of a smoke consumer having a draft flue for conveying to the fire-box a draft sufficient to cause the smoke to pass through consuming pipes carried therein whereby the carbon and other elements of the smoke will be consumed at which time the draft will cause the air and gases to be expelled. Y y

Still another object of this invention is the productiony of a smoke consumer having a plurality of air pipes to which the draft iiue is attached whereby the draft from the flue will be evenly exhausted from the air pipes, through the grate, into the fire-box of the furnace for causing a free circulation of the smoke after the same leaves the re-box.

With these and other objects in view'this invention consists of certain novel combinations, constructions, and arrangements of parts as will be lhereinafter fully described and claimed.

Referring tothe l accompanying drawings -Figure 1 is a central vertical section through the smoke consumer showingthe same in an assembled position and illustrating portions of the device in elevation.v Fig2 is a front elevation of the'assemlbled device.

Fig.v 11 is a detailed perspective view of a draft operating arm'used in connection with this device. Fig. 12 is a fragmentary perspectiveview Vof a certain drawer used in connection with this invention. Fig. 13 is a vertical section through a slightly modified form of the draft funnel. Fig. 14E is a side elevation of the draft funnel as disclosed vin Fig. 13 showing the outward plate of the fan-casing removed. Fig. l5 is another forrn of the draft funnel.

Referring to the accompanying drawings by numerals 1 designates the side of the fire box which carries the grate 2 at a spaced distance from the base 3. The distance between the base 3 and the grate 2 forms the ash pit 4L from which the ashes may be removed by the doors 5; The projection 6 carried by a portion of the fire box 1 assists in carrying the boiler casing 7 so as to support the plate 8. This plate S extends entirely across the interior of the boiler casing 7 so as to form a separate compartment above the plate 8. The boiler 9 having the longitudinally ex-` tending boiler tubes 10 is supported upon this plate 8 so as to allow the end portions of the boiler 9 to'be positioned ata spaced distance from the end portions of the boiler casing 7 thereby providing

compartments

11 and 12 at each 'end thereof.' The exhaust iiue 13 extends above the boiler casing 7 and communicates with the space `12 at one end of the boiler 9.V The present invention isused for consuming the carbon contained in the smoke which is generated in the `fire box 1 and passes through the boiler tubes 10.

The elbowsli carried by one end of the fire box l is integrally formed upon the draft iue 15 which extends vertically. This draft flue 15 carries an annular shoulder 16 upon which the lower end of the draft funnel 17 rests. This draft funnel 17 is also provided wit-h an integral annular shoulder 18 resting l draft flue 15.

upon the upper end of the draft flue 15. This draft funnel 17 Vis also provided with the handles 19 Afor allowing the 'same to be easily turned in a desired directi on to catch the wind for causing the wind to pass down into the draft flue 15. The shoulder 16 is provided-with a plurality of notches 20 for the reception of the pivoted linger 21 which is-pivotally secured to the draft funnell as shown at 22. It will be seen that by raising the` pivoted finger v21 and by grasping the handles 19 the `draft funnel 17 may be swung in a desired direction for catching the wind and oausing Athe same to `pass downwardly into .the interior of the draft flue 15. The

yfinger .21 may then be released and the weight `of the finger will cause the same to fall andrest within one of thenotches 20 thereby holding' the draft funnel in a set position and thus prevent the wind from blowing the funnel around and diminishing the current of air passing down into the nected to the secondary portion 23 ofthe draft flue 15v and' this secondary portion 23 passes YintoV the opening 24` communicating c with theroom 25 formedatfone end of the sol ' shaped elbow 35.

drawer 26. This drawer 26 is also provided withY openings 27 communicating with the room r25 andthe air pipes 2S are positioned within the drawer 26 so asto have their end portionspassing through the openings 27 to communicate withjthe room`25. rThese pipes 2,8 are also provided with apertures 29 in their upperportions so that when the air is passed from the flue 15 into the room25 it will be equally distributed into the air pipes 28 from which it will be discharged through It is to be observed, however, that the passage of air erating the valve disk 30 by means of the handle 31.. Vilhen, however, the air passes from the air pipes 28 through the apertures `29 it will pass upwardly through the grate 2 and into the fire box 1. The passage of this air into' the lire box will cause the fire to vburn and therefore it will be necessary to provide a means for consuming the smoke.`

Upon the grate2 there 1s carried a pair `of spaced blocks 32 which carry the consuming pipe 33. r1`his consuming pipe 33 has the'parallel spaced portions 34 communicating with each other by means of the U- One portion of the parallel consuming pipes 34 carries the funnel 36 while the other portion is provided with the rstraight pipe 37 extending upwardly GO and passing through the plate 3 so as to communicate with the compartment 11 formed at one end of the boiler 9. .The funnel 36 however is positioned within the lire box 1 so as to have its open portion adjacent the under surface of the plate 8.

This, consuming pipe is adapted to have. its

r)The-,elbow 14 is also con-y through the plate S and communicating with the compartment 12 at one end of the boiler 9. The opposite end of the consuming pipe y3S has a depending portion 40 terminating in the upwardly bent end 41 which rests upon the grate 2. 1t will be noted, however, that the upturned end may direct the eurrent of air upwardly into the fire box 1 and will prevent the air currents passing upwardly from the air pipes 28 having admission to the secondary consuming pipe 33. Since the upwardly bent portion 41 and the depending portion of the secondary consuming pipe 3S are positioned within the tire box they will be heated by the fire within the box to a very high degree whilel the secondary consuming pipe 33 will also be heated owing to the fact that the space between the projection 6 and the plate 3 communicates with the lire box 1. .f1 hood 42 is carried at the upper portion of the compartment 12 and has a reduced neck 43 provided with a valve disk 44. T he rod Al5 is connected to this valve disk 44 and has a crank portion 46 to which the arm 47 is connected. `When the device is in operation, the draft funnel 17 may be swung into positionto catch the wind. The wind will then travel down into the flue 15 and thence into the air pipes 23. The air within these pipes will then be expelled through the apertures 29 into the fire box. Since the funnel 36 has its open end positioned so as to receive the air currents as disclosed by the arrows in Fig. 1, the lire which is being built withinthe fire box 1 will pass into the funnel and then through the consuming pipe 33. The fire and smoke will then pass through the vertical pipe 37 into the compartment 11 and then through the tubes 10 of the boiler 9. At this time the rod should be turned by means of the arm 47 so as to open the passage-way through the neck 43 of the hood 142, The smoke may then pass into the compartment 12 and be expelled through the neck 43. At this time the valve 43 carried within the secondary consuming pipe 3S will be in a closed position. 1t will be seen that at this stage the smoke passing from the neck 43 will contain carbon and particles of material which is causing a waste and also the danger of sparks and the objectionable features accompanying the exhaust of smoke. lVlien. however, this action coutinued for a short while the consuming pipe will be heated as will the secondary consuming pipe 3S having the depending portion 40. As soon as this has been accomplished, the valve 48 may be opened while the valvev disk 44 may be closed. The current of air will cause the smoke to pass into the funnel 36 and through the parallel. portions 34- of the consuming pipe 33. Owing to the fact that this pipe will be positioned within the fire box and within the bed of coals it will be heated to a very high degree and will therefore burn the carbon and other objectionable elements in the smoke as the smoke passes therethrough. As the smoke is then freed from the carbon and other elements, the gases and heated air will pass into the compartment 11 as'shown by the arrows in Fig. .1. rfhese gases and air will pass through the tubes 10 of the boiler 9 and then downwardly as shown by the arrows in Fig. 1, into the elbow 39. The gases and air will then pass through the secondary consuming pipe 33 and through the depending portion l() to be expelled from the upwardly bent portion 4l and secondary consuming pipes 38 into the lire boxl l. rlhere is formed., however, upon the depending portion -ilO of the secondary consuming pipe 38 an exhaust pipe which communicates with the ash pit. This exhaust pipe 49 is also provided with a valve disk 50. By having this exhaust pipe 49 when it Vbecomes necessary for the burnt gases and air to pass from the secondary consuming pipe 33 and depending portion 40 instead of passing into the lire box 1, the burnt gases and air will pass into the ash pit l. The doors 5 at this time may be opened so as to allow the burnt gases and air to be expelled from the .ash pit. lt will be seen that by the use of this exhaust pipe 49 whenever it is necessary for the burnt gases and air to be expelled, they may easily pass from the secondary consuming pipe. lf. however,

all of the burnt gases and air do not pass from the depending portion 4:0 and the secondary exhaust pipe 33 they will be passed into the fire box so as to be circulated again. lt is however obvious that after passing through the heated exhaust pipe 33 and through the secondary exhaust Apipe 38 all the inflammable material of the smoke will be consumed thereby allowing the gases and air to be exhausted without danger of fire by sparks and also eliminating the objectionable features accompanying the escape of smoke in its ordinary condition.

ln order to facilitate the conductingof the draft, a reduced tube 51 is carried within the draft flue 15 and extends outwardly and around the outer portion of the draftiiue adjacent the valve 30. The tube 51 then extends again into the draft flue 15 as shown at 52 and then extends beneath the elbow 11i and the outer portion of the lire box so as to extend again into the iirebox as shown at 53 above the grate 2 and then have its end extend into the vertical portion 37 of the consuming pipe 33 as shown at 54:.

As the air passes downwardly into the draft iiue 15 by means of the draft funnel 17 a portion of the current of air will pass downwardly'through the tube 5l and .into the vertical portion 37 of the consuming pipe 33. This will cause the air currents through the consuming pipe 33 to be heated owing to the fact that the admission of the air current by the tube 51 will be adjacent t ie portion of the consuming pipe 33 from which the air and gases ofthe burnt smoke are expelled.- A secondary tube 55 is also carriedwithin the flue 15 and has its lower portion 56 extending from the flue 15 so as to have the horizontal portion 57 extend beneath the grate 2 and be connected to the vertical portion 58 communicating with the interior of the secondary consuming pipe 3S as shown at 60. This tube will also receive a direct supply of air from the funnel 17 and will convey this air into the secondary consuming pipe 3S for causing a current of air upon the opposite side of the boiler casing to that upon which the draft flue is carried.

Each air pipe 28 has at its open end a valve disk 61 having a crank arm 62 to which the lever 63 is connected by passing the crank portions of the valves carried by the air pipes 28 into the apertures .64 formed in the lever 63. If some of the cinders or coals from the fire box fall through the grate and into the air Vpipes 28 by passing through the openings 29 the lever may be pushed for swinging the valve disk 61 thereby opening the free end of the air pipes 28. The force of the air within the air pipes 28 will blow the refuse from the interior of the air pipes. The lever may again be pushed for closing the open ends of the air pipes whereby the currents of air will be directed into the fire box. IThe draft flue 15 may also be provided with a stop-cock 65 for allowing any water which might be contained within the draft flue to be easily expelled therefrom. ln order to support the drawer 26 in its correct position there are provideda plurality of brackets 66 which are fixedly secured to the side portions of the casing forming the ash pit at a spaced distance below the grate 2.

By referring to Figs. 13 and lt it will be seen that a slightly modified form of a draft funnel has been produced to which the funnel 67 has a fan housing 63 connected which is closed by the plate 69. Within this housing, the fan 70 is positioned and adapted to be rotated by the groove-pulley 71. The reduced Vhood 7 2 is formed integral within this draft funnel 67 so as to direct the lcurrent of air from the fan 70 downwardly into the draft flue 15. lThis draft funnel performs all of these functions similar' to the funnel disclosed in the preferred form and the only change in this form of the funnel is in the fact that the fan 70 1nay be used to increase the air, current provided there is'n'ot a suiriicient amount of air passing int-o Athe funnel to supply the several portions of the consumer vwith the air currents.

By referring to Fig. lit will be seen that another form of the funnel member has been produced in which a sleeve 73 may be carvried upon the dra-ft flue l so as to allow the annular vflange 74 to rest upon the upper portionof the draftiiue 15. in this form of the device, however, there'may be pro- Y Yvided a plurality of reduced funnels 75 ywhich are so Vpositioned within the upper portion of'the sleeve 73 as to allow their lower portions to rest upon the annular flange 74 while their enlarged outer portions will rest upon the upper portion of the sleeve 73 and furthermore the size of the bodies of these funnels will cause the saine to remain' in snug engagement within the sleeve 78. This form of the invention may lbe also provided with a plurality of tubes 76 extending upwardly into the funnel members 75 and then communicating with Vthe pipe 77 which is used instead of the

tubes

51 and 55 of the preferred form of the j Y invention. f

From the foregoing description it will be seen that an eiiicientsmoke consumer has been produced in which ,the smoke must pass through the consuming pipes which are heated so as to burn the smoke and thus cause the burnt gases and air to be easily discharged from the consumer while the consuiner is also rprovided with an efficient ing pipes, a plurality ofair pipes carried within said drawer, a draft flue carried by said fire box and communicating with said drawer, said draft flue being adapted to convey a Lcurrent vofY air into said drawer and into said air pipes whereby the air may be passed up into said fire box for causing the smoke tobe passed through said smoke consuming pipes whereby the inflammable material of the smoke may be burnt atwhich time the burnt gases may through said boiler and be exhausted.
