REFUSE-INCINERATOR CONSTRUCTON AND SHOPPER DOR THREFOR i Application filed April 13,

This invention relates to refuse disposal construction in the nature of those associated with incinerators and more particularly to hopper doors therefor. Y

Where I have attempted to provide in building construction refuse disposal chutes or flues whereby ashes, garbage or similar refuse may be deposited and gravitated to receiving receptacles or consumedin an incinerator, considerable difficulty has been encountered by reason of the draft created attendant to opening and closing of the flue openings tending to Whirl particles of dust or still more objectionably drawing in odors of burning refuse.' Where the flues are used in connection with heating plants, the element of loading of these flues for depositing refuse therein has been a still further objectionable source of disturbance to the bed of fire, creating drafts serving to uneconomically consume the fuel. Aside from these ditculties, where these disposal devices are used in households, a tendency to overload and jam the flue opening with refuse has been occasioned by the continuous opening permitted by doors used in connection with incinerator constructions lmown to me, still further adding to the difficulties encountered as above enumerated, during use, as the period of loading is thereby further increased.

My invention therefore has for an object thereof the provision of a refuse disposal construction such as incinerators and hopper or closurel members for the flue thereof, permitting loading without disturbing the currents of air in the flue opening, characterized by a door or hopper which serves toseal the fiue opening under all conditions of use; the provision of a refuse disposal flue 4having a loading door or hopperfor the loading opening thereof characterized by the door or hopper serving as a seal for the loading opening in any position thereof; the provision of a refuse disposal system or incinerator, and a loading door or hopperv for the loading opening thereof comprising a pivotally partitioned member coacting with the arcuate guiding walls in the opening, with the partition members serving to seal the opening in all positions; the provision of a hopper 1927. Serial No. 183,250.

door for the feeding opening of an incinerator flue comprising a plural partitioned, pivotally mounted member' associated with an ar-' cuate wall in the opening of said incinerator whereby one of said partitions on said member may be in contact with the arcuate wall to Y seal the opening under all conditions of use,

thereby avoiding the induction of dust or noxious gases into the living room and avoiding any disturbance in the fuel bed by setting up drafts, normally occasioned by the loading and opening of the hopper door.

My invention still further has Vfor anob-v l ject thereof the provision of a hopper door` for a refuse disposal systemjsuch as incinerators, characterized by simplicity of construction, economy of assembly, pleasing inappearance, and at-the same time including fea-V tures such as leaving substantially undisturbed the air pressure inthe flues ofan incinerator by avoiding the creation of-drafts and the induction of objectionable dust andgases into the living room when loading or. otherwise using the incinerator system. Still" further, my invention contemplates the provision of a hopper door for incinerators which will not become out of order, occasioned by over-stuffing of theflue opening, characterized by they provision of a hopper door which 'at' no time permits direct feeding-of refusematerial to the flue. i 1 l To attain these objects and such' further objects as may appear herein or be hereinafter sol pointed out, I make reference to the accomf4V panying drawing forming'aV partV hereof, Yin whichv v j Figure 1 is a side elevation in section show-.1 ing 'my device as connected to the-wallof an incinerator flue; Y n w Figure 2 is a view similar to Athat Ashown in Figure 1 in the closed position;

Figure 3 is a front elevation. H Making reference to the drawings, it will be observed that my device maybe applied to the wall 10, having an opening generally referred to 11, connectingv with the flue or shaft and extending laterally into the interior of the room fromwhichV refuse matter, garbage, ashes or the like may be deposited to the flue, leading into a storage device, incinerator or the like. The construction permitting loading into the opening comprises a y frame referred to generally at 12, preferably tially 90.

made of a frontal section 13 and a rear section 14, having inwardly directed flanges 15 and 16 overlapping, through which may be passed a rivet or similar fastening device 17.

The frame is further provided exteriorly thereof with a plaster bead 18 adapted to lie flush with the inner face of the wall 10. The

frame 12 is provided with a main vopening defined by the inwardly directed` side wall flanges 19, the upper wall 20 being formed arcuately as a segment of a circle of substan- This arcuately formed portion may beincluded entirely by the section 13.

rPreferably, however, thisl arcuately formed wall is disposed to have a portion thereof 21 formed in the frontal portion 13 and an additional portion 22 formed in the rear portion 14 so as vto be contiguous therewith. Upwardly extending flanges 23 and 24 form lap joints through which may be passed a fastening member such as a rivet 25. The

l bottom wall of the opening is preferably vformed with downwardlyjinclinedwalls 26 i formed in the frontal portion 13 and in align tion members 31 and 32, disposed substanment with the portion 27 formed in the rear frame 14.- The side walls 19, 19 of the frame are provided adjacent the bottom wall 26 with offset bearing portions 28, 28. These bearing portions are preferably downwardly inclined slots forming bearing seats 29.

Into the openingV just described, there is` disposed a hopper door 30,'including partitially at right angles to each other, and side wallsv 33 arcuately shaped, corresponding to the arcuately shaped wallsi21, 22 above described. A handle member 34 is provided on the partition wall 31 for suitably operating the hopper in a manner which will be apparent as? this description proceeds. The side walls 33 are provided with bearing pins'35 f which Yare positioned adjacent the corner formed by the intersection of the partitions 31 and 32. The curved Walls 33 are preferably set ofi Valong the edge 36 between the edges A37 Vand 38 of the partitions numbered 31 and 32,-respectively. Y y

To position the hopper 30, this member is inserted in the opening, first insertingthe edge 38, until the pins rest in the bearing Vportions 28, upon the seat 29. The hopper 'lower edge 40 of the wall 22; In this ber 31, further serving to seal the opening 11 and acting as a stop in cooperating with the bottom wall to prevent furtherV rotation. This lug 39 is positioned about midway of the arcuate wall formed by the portions 21 and 22 and extends across the full length thereof. For loading material into the incinerator flue, rotation is given to the hopper door by grasping the handle 34. In Yits rotation inwardly about the pins 35, it will be observed that the partition member 31l serves to seal the opening throughout its movement until the position substantially shown in dotted lines in Figure 2 is reached. As the partitions 31 and 32 are positioned to subtend an angle equivalent to that of the arcuate walls 21 and 22 in the position shown in dotted lines inv Figure 2, the edge 38 will Vbe adjacentthe tion, it will be observed that the inner partition member 31l is just passed'theI opening defined by the side walls 1,9 and 20. Here, again, in this position it will bezobserved that the partition member 32 serves to seal theV Further movement opening 11 of the fiue. Y inwardly to that shown in Figure 1 maintains the edge 38 in substantial contact with the arcuate wall 22 until the edge 38 abuts the lug 39, preventing further rotation. In'this position, however, the partition member 31 has passed the edges of the walls 19 and 20,

giving access to the interior of the hopper.'

In this position, refuse material may be load"- ed into the hopper door to completelyl fijll ther same. It will be further observed thatv no material may be forced into the flue opening posi- 11 beyond thecapacity of the hopperV 30.

Furthermore, in its loading position, thepar` tition memberY 32 serves'to completely close and seal the opening 11. y

To unload the contents deposited within the hopper 3Q, pivotal rotation to the right isv effected until the partition member 32 rests upon the angularly -disposed walls. 26

and 27 and the edge 37 of the wall 31 abuts the lug 39. The material deposited within the hopper will thereupon `gravitate down the inclined angularlypositioned wall 32 into the'flue directed to any receptacle 0r incinerator. I Y

It will be observed that the partsma'y bel made of suitable fire resistant material such as sheet metal or metal casting without de parting from the spirit-and scope ofmy A"in-t It will be further cbserved'that though I have described the arcuatev wall and vention.

partition members as each ldisposed to subtend an angle of about the hopperwalls corresponding to 31 and 32 may be further divergent if the sealing wall be additionally extended.

It will thus be' observed that I havel provided an incinerator or' similar refuse dis-V posal system which is substantially simple and inexpensive, at thesame timeproviding a device which is fool-proof against undue loading to render the device inoperative and one which is free from the obiections of disturbing the air currents in the flue of the Y incinerator by reason of the provision of a seal in all positions of operation in respect to the loading opening. It will further be observed that in the preferred form as shown, the hopper door is so disposed as to automatically close upon release of the handle by the operator after depositing any material in the hopper door.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is-

1. The combinationwith a flue wall having an opening therein, a frame fitting into the opening comprising a frontal section formed with a plaster bead and inwardly directed flanges, a portion of which is arcuately formed, a rear section including an inwardly directed flange comprising an angular extension at thev lower side and an arcuately formed wall at the top side, the anges of said sections being capable of being fastened to form a smooth continuous1 arcuate wall and cooperating to provide means for confining the masonry of the wall,

a hopper pivot concentric with the arcuate wall and a hopper embodying diverging sides proportioned as radii of an arc and moving upon the pivot with one of the sides at all times in Contact with the arcuately formed walls. u

2. The combination with a flue wall having an opening therein, a frame fitting into the opening comprising a frontal section formed with a plaster bead and inwardly directed flanges, a vportion of which is arcuately formed, a rear section including an inwardly directed flange comprising an angular eX- tension at the lower side. and an arcuately formed wall at the top side, the anges of said sections being capable of being fastened to form a smooth, continuous, arcuate wall and cooperating to provide means for con- Y fining the masonry of the wall, a hopper pivot concentric with the arcuate wall and a hopper embodying diverging sides proportioned as radii of an arc and moving upon the pivotwith one of the sides at all times in contact with the arcuately formed walls, an outwardly turned lip on said frontal section for said hopper pivot, angularlydisposed in subst-antial alignment with said angular extension whereby a lateral and continuous extension is formed for the hopper in its dumping position.

In witness whereof, I have hereunto signed my name this 11th day of April, 1927.
