REFUSE-BURNER.
Specification of Letters Patent. Patented Ja,n 1911,
Application filed October 27, 1909. Serial No. 524,981
To all whom it may concern:
Be it known that we. JOHN R. FORTUNE and IIAROLD S. Wrens, citizens of the United States of America, residing at Detroit, in
the county of Wayne and Sinte of Michigan,
have invei'ited certain new and useful linprovemenls in Refuse-Burners, of which the following is a specification, reference being bad therein to the accompanying drawings.
This invention relates to a refuse burning furnace and its object is to provide a furnace for the purpose so arranged and coir other new and useful features in the 0011- strnction, arrangement and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings in which, v
Figure 1 is a transverse vertical section through a furnace embodying the invention; Fig. 2 a longitudinal section of the same substantially on the line :c:c of Fig. 1; Fig. 3 is a PGFSPQC? detail of three of the feed bars; and F 1 is a similar View of one bar with part of the pusher blocks removed and. the other pa y broken away to show the construction. i
As shown in the drawings, 1 and 2 are the outer side walls of a furnace and the ash pitat ihe bottom of she fire chamber at over which chamber springs an arch 5 curved longitudinally of the fire chamber and extending laterally from the. wall 1. Omar the arch 5 ai a distance above the same is second arch 6 which springs from the side wall 1 and extends across to a suitable arch plate '2' forming one side of the throat of a hopper 8, the opposite side of the hopper being formed by the side wall 2 and an inwardly and downwardly extend ing plate 9 supported and strengthened along its lower edge by an angle bar 10 supported at a short distance inward from .aid wall. Within the fire chamber 4 above the ash pit 3, is supporqed a grate bearer each bar with its blocks reseniblin -11 upon which the lower ends of the inelined grate bars 12 rest, the upper ends of said bars being supported by a suitable channel iron iii to which is secured an angle plate 14: extending along one side of the fire chamber throughout its length. The grate bars and their supports may be of any suitable well known construction.
A supporting structure formed of channel bars 17 forms a support for the lower ends of reciprocable feed bars 16 which are tend in an inclined position across the dryinn and coking chamber 27 located between the open. side of the fire chamber and tlre hopper, and the upper ends of said bars are supported by similar channel bars located near the wall 2 beneath the open lower end of the hopper 8. These bars are.
all supported at their ends upon rolls 18 so that they may be easily moyed longitudinally in an approximately horizontal plane. said bars being formed at each end with a horizontally extending portion or rib 19 to engage said rolls. 7
Supported in suitable bearing brackets secured tothe lower side of the channel bars 15, is a rock shaft 20 and to upwardly and downwardly extending arms 21 on said shaft are pivotally attached connecting bars 22,.the opposite ends of which are piv otally attached to downwardly extending lugs on the feed bars 16. WVhen the shaft 20 is rocked by any suitable means, not shown, every alternate feed bar is moved for- Ward as the intermediate bars are moved in the opposite direction and the upper edg of each. bar is notched or stepped to r'orni a series (if-seats for a series of pusher.
in appea once, the blocks resembling; l; stair treads. Each pusher-block is detachably attached to its bar by a pin extending through an our 25 on the bar and a web 26 on the block. The blocks on each bar are of a length to fit loosely between the two adjacent bars and. the transversely alincd blocks on the alternate bars-together form ledges or shelves extending the length of the furnace and the blocks of ach row or ledge being all carried by bars which are moved sin I 'aneously in the same direction, each ledge or shelf is moved forward and back as a whole. The bars are so made and the blocks secured thereon insuch relai positions that the rows of blocks carried by one sitof oars each lie between the adjacent are of such a Width that the rows overlap and thus the material upon the feeder is rerows oi blocks carried by the other'set of bars, and thus each row or ledge is moved outward as the row next above and the row next below are moved. inward. The blocks vented from dropping through. The s id ing of one row of blocks upon another, gradually feeds the material from the hopper downward and deposits it upon to upper ends of theinclined grate bars, at the same time spreadi'ngnnd mixing the same as it; asses downward. The refuse to be burned is thus spread out in it comparetively thin layer over a large area and mixed and'stirred as itis fed downward, to present everyv portion ofit to. the action of the hot products of combustion whichsre directed over it by the arch 5. The material is thus thoroughly dried and may, in some instances, be ooked by the time it reaches the grate bars. The rapidity with which it will be fed from the hopper may be regulated by the speed stwhich the rock shaft is operated to actuate the feed-bars. The out let 28 for the pijoductsot combustion is be tween the archeso and Q almost opposite the opening through which the refuse enters and thus a strong current of air is drawn in through the hopper, preventing the fire from burning up into the hopper and this air current following along the surface of the arch 6 mixes with the gases and combustion without interfering with the drying and coking of the refuse.
From the outlet s one 28, the products oi combustion escape t rougho ilue29. The arch o'being curved longitudinally of the fire chamber 4: tends to direct the products of combustion toward its highest port inter mediate the ends of the chamber where they pass from said chamber above the lower ends of the feed bars and out through. the openingbetween the arch 6 and the edge of the arch 5. By curving the arch 6 oppositely to the arch 5, the lower edge of said arch G is brought down to the mouth of the hopper and it curves upward therefrom over the arch 5 causing it current of air from the hopper to How. along its inner surface where it mixes with the gases and aids combustion,
then passes out through the outlet. I v
Having thus fully described our invention what we claim is hoving a re srchthereover, a hopper l13.V'
semesan open lower end supported at a distance from the, end of the'fire arch, in second arch curvin upwardly from the 0 en lower end of sa-i hopper to a point e ove said fire arch with'sspace between soid'erches form- .ing tin-outlet for the products of combustion, and inclined feed members extending from beneath the open lower end of the hopper to the open side of the fire chamber.
2. A furnace of the character described comprising a fire chamber open atone side 1nd having a tire arch'extending thereo'ver, a. hopper supported at distance from the open side of the fire chamber and having on open lower end extending the length of the said open side substantially in the plane of said fire arch, an arch curving upward from the lower end of the hopper across the said space between the open end of the hopper and the open side of the'jire chamber and 5 extending over the tire arch at a distancev shove the seine to form a space between said arches tor the passage of the products of conibust'on, inclined grate bore supported Within tie fire chamber with their upper ends ad acent to the open side of saidohomher, inclined movable members extending from the upper ends of the grate bars to beneath the open jower end of the hopper,'
and means for actuating said members.
3. In a refuse burning furnace the-combination of e tirechember. having on open side and provided with is fire ei ch extending thereover, 2 hopper extending the length of the iirechainber and located at a distance from the open. side of said. chamber, said" hopper having provided I with an. arch plate forming one side of the throat oi tthe hopper-5 and provided with a seat for an arch otits lower end, an arch engaging said seat and curved upwardly therefrom and extending over the lire arch with 11v space between said arches an open lowerr-end, audios for the escape of theproducts of combos tion, inclined grate bars within the tire chamber with. their upper ends su ported adjacent to the open side of said c ember, inclined feed members extending from the upper ends ofthe grate bars upwardly be-' necth the open lower end of the hopper, and
means for actuating soid teed members.
in testimony whereof we afiix our signs-- tures in picsence of two witnesses.
