T at whom, it may concern.- y
Be it known that'I, HERMAN A. Porrnunn- SEN, a citizen of the United States, and a resi dent of Evanston, in the county of Cook and .State of llllinois, have invented certain new and useful Improvements in Ash-Removing Devices for Furnaces; and l do hereby declare that the following is. a full, elear., and exact f description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. 1
This invention relates to improvements in meansfor removing ashes from the ash-pits from boiler-furnaces; and it consists in the matters hereinafter described, and pointed out in the appended claims.
My invention may be more readily understood by reference to the accompanying drawings, in which' 7 Figure 1 1s a V ew in central longitudinal section of a bo1ler-furnace together with ashretnoving devices embodying my invention.
the furnace shownin vertical section, said sec tion being taken .upon line 2 2 of Fig. 1.-- Fig.
Fig. 2 is afaceview of two furnaces like that shown in Fig. 1 with parts relating more especially to the removal of the ashes from I 3 is a detail section showingparts of a hoistan endless traveling grate D, the same being in Fig. 2. ,The grate-supporting frames, of
ing device for removing the elevator constitut ing part of the ash-removing device, said section being taken upon line 3 3 of Fig. 2; Fig. t is a detail section taken on the indirect line 4C aof Fig. 1, illustrating parts of the ash-re: moving devices in elevation. Fig. 5is adetail section taken on line 5 5 of Fig. 1.
As shown in said drawings, A indicates the front wall of a boiler-furnace; Ahone offthe side walls thereof, (shown onlyin Fig. 1;) A,
the bridge-wall'of the furnace, and B a, boiler,
whiclnas illustrated, is of the water-tubetype.
C C indicate the side frame-plates of an automatic stoking device of that kind having indicated in outline in Fig. 1 and in outline which C U are the side'frame-platcs, are supported bywheels c c, whiclrrest and, travel upon traclerails F E, which extend into the furnace-chamber from front to rear ofthe verging surfaces G furnaces and outwardly through the front wall ofthe furnace, so as to permit the gratcsupporting. frame and grate to be withdrawn from the furnaces when desired. A indicates the fire-arch, locatedover the front portion of the grate or adjacent to the fuel-feed opening thereof. V
The. parts above described are arranged as heretofore common in boiler-furnaces.
Now referring to'the parts more directly connected with my present invention, F, Figs. 1 and 4., indicates a horizontal partition or arch which spansxthe space beneath the outer ashes which is discharged or falls from'the I rear end of the traveling grate into the chamber Gr. sBaid chamber G has a downwardly and forwardly inclined bottom surface (i which reaches from a point below the bridgewall downwardly and forwardly to the front part of said "chamber-G. The upper partsof the side walls oflsaid chamber Ur are vertical, as shown in Fig. at; butthe lower parts thereof are provided with inwardly-con- 4 The front of the chamber Gr is closed by means of an inclined or oblique partition wall or plate H, preferably formed of metal and set at its edges in the masonry forming the side walls of llllG (illitlll bent}; Said partition-wall H is inclined downwardly and rearwardly, its upper margin being connected with the forward margin of the horizontal partition F. At the lower part of said partition-wall H is formed a gate or openingprovidedwith-a sliding gate or valve H. Said gate or valve H is shown as provided with a chain it, which extends up wardly to a point within reach of. the operator on the floor of the fire-room andby means of 'Whichthe gate may be raised or lowered.
e aid inclined wall H, together with the in-- clined bottom surfaces G G of the chamber G, constitute, in efi'ect,a hopper-bottom in said chamber, the rear inclined surface G sloping to the lower part of the opening of said partition H, while the lateral inclined surfaces G G terminate at the'bottom of the chamber adjacent to the sides of said opening. It follows from this construction that ashes delivered to the chamber G through the passage G tend to accumulate in the bottom of the chamber G adjacent to the opening in the partition H and when thegate H is lifted will pass by gravity through said opening.
At the front of the ash-chamber G is located a pit I, the bottom of which is on or below the level of the bottom of the chamber G and which-is separated from the said chamber G by means of the partition-wall H. In the pit I islocated a portable endless belt or bucket elevator, (indicated asawhole by J The pit I may be only large enough to receive the elevator; but preferably it is made of size large enough to permit the entry thereto of a workman to clean out the pit. Said elevator J em braces a supporting-frame which carries bearings for the movable or working parts of the elevator and which is itself movably supported within the pit I Said elevator J is located adjacent'to the outer face of the partition-wall H, with its lower or receiving end adjacent to the valved opening in said partition, -said parts being so arranged that ashes discharged from the chamber G through the said door or opening in the partition-wall will be received by the upwardly moving buckets of the elevator, which upwardly-moving buckets are located in the side ofthe elevatoradjaceut to the wall H. Moreover, said elevator J is arranged in an inclined position and preferablyparallel with said wall H. Beneaththe lower end of the elevator is located a metal trough'or casing K, which forms a well or depression into which the lower end of the elevator extends and which itself extends below the bottom of the chamber G and the pit I. Said well is adapted to receive ashes which may fall through the opening in the wall of the partition H and which is not caught by the upwardly-moving buckets of the elevator as they pass through said opening. The casting K is embedded in the masonryconstituting the shown as attached at their lower ends to theouter margin of the casting K and as secured at their upper ends to a transverse supporting-bar L, which extends across the top of the pit I at the level of the floor of the fire room. Said elevator J is made of such length as to extend considerably above the said floor out of the way of the person or persons operating the furnace and the intent being that the elevator should be inserted in place within the pit only "when it is desired to remove the accumulated ashes from the chamber and that as soon as it has served its purpose as a means for removing such ashes it should be taken out and either shifted to a like pit of another furnace, such as is shown in Fig. 2,
or moved in someother place where it will be out of the way of the operator of the furnace or furnaces. x
The frame of the elevator J consists, as
herein shown, of two longitudinal side pieces J J, that are connected by cross-girths j j.
On the opposite ends of the frame-pieces are mounted pulleys J J over which are trained chain belts j j, to which are attached the buckets j f of the elevator; side of the elevator the frame is provided with guide-pulleys f 1' Suitable provision is made for driving the elevator, consisting in the instance shown of a driving-pulley J attached to the shaft of the pulleys'J outside of one of thesideframepieces of the elevator. To facilitate the insertion and removal of the elevator,the frame thereof is provided with a plurality of hear ing or supporting rollers J J which are attached to cross-shafts mounted on theframe members J and adapted to bear or rest against the rails LL. Said rails'are flanged, as shown in Fig. 5, so as to hold the wheels from sidewise movement, and thereby retain the eleva At the rising j "for the chain belts j.

tor as a whole from lateral movement when it is supported upon or by saidrails.
1 So far as the general features of my invention are concerned the elevator maybe shifted or removed from its place in said pit I and be placed therein by hand or by any suitable lifting means that may be adapted for the purpose. I have shown in the accompanying drawings, however, a convenient form of device for this purpose adapted for the hoisting ,of the elevator endwise out of its place in the pit until its lower end is above the floor-level and the carrying of said elevator horizontally when in its said suspended position to a point over a similar pit of another furnace'or elsewhere or to some other point where it will be out of the way of the person operating the furnace. The devices for this purpose herein shown are asfollows: 'As indicated in Figs.
I end of the elevator J .when the same is rest-- reason Qand 3, 0 indicates a supporting-track, which is suspended from the roof or ceiling of the structurein which the furnace is located and arrangedparallel with the frontwall of the furnace or furnaces at a point above the upper ing in its place within the pit l. Said track is shown as consisting of an I-beam. On said track U is supported a wheeled carriage P,
consisting, as shown, of two rigidly-connected side plates provided with bearing wheels or trolleys 79 99, that en gage outwardly extend ing lower flanges on the l-beam, The carriage P is provided with pulleys p 19, overwhich are trained two hoisting"- ropes QQ. The
lower ends ofthese ropesare connected with the elevator preferably-by means of a yoke or frame Q], as shownin Fig. 4. Thelower ends of said yoke Q are pivoted to the upper ends of the sideframe-pieces J J of the elevator. On the depending ends of the hoistsert the same.

points near the floor,'so that they-may be easily grasped by operators when it is desired to hoist the elevator from its place in thepit,
From the above it will be readily understood that when the hois'ting and transferring devicedescribed is employed audit is desired to effect the removal of ashes from the ashreceivinglchamberG of one of the furnaces the hoisting device, with the elevatorsuspended therefrom, will be shifted'or moved along the track 0 until the lower end of the elevator is overthe pit into which it is desired to inered and will be guided or directed so as to bring its lower endintothe desired position, the rollers J J being caused to run upon the supporting-rails L L. After the elevator has been lowered intofits working position a belt 1 from the pulley on a suitable counter-shaft is trained over the drivingapulley J and the elevator started in operation. 1 Instead of such belt-pulley a crank J asshownin Fig. 4;, may be employed, by which the elevator may be operated by hand. Thecar will beplaced l.beneath the upper end of the same in position to receive the ashes delivered from the elevator buckets. The door H will. then be ifted or opened to'permit the ashes to pass from the chain her-receptacle 'E to the lower end of the elevator, and the elevation and discharge of the ashes will then continue until the cham- Theelevator will then be low with an ash-receiving chamber beneaththe saline and an elevator-pit at the front of the furnace said chamber having a hopper-bottom inclining toward said pit, of a portable elevator embracing an elevator-frame pro vided with pulleys and with a belt equipped with buckets; said elevator being movable as i a wholeand adapted for insertion endwise into said elevator-pit and hoisting and conveying means located over said pit for ra1s- Vator. i 2.
