This invention relates to certain improvements in incinerator doors, particularly to an improveddoor for closing the opening in an apartment leading to a chute-fed inciner .ator. r v
The principal object of this invention is to provide an incinerator door, a door frame, and a supporting casing which is imbedded in the building wall, these members being provided with integral parts adapted to co operatively engage whereby the'door will'be pivotally mounted on the frame, and the frame securedto the casing, so thatsubstantially all of these connections will be hidden when the parts areassembled and the door is closed, and the. door and frame will present only smooth exposed portions which may be completely coveredwith a'vitreous enamel, or other suitable coating toharmon'ize with the wall decorations and present an attracv tive and ornamental appearance;
The above, and other objects from the following detailed description of one approved form of assembly, embodying the principles of this invention,
In the accompanying drawings:
Fig. 1 is, a vertical section through a por- Fig. 3 is a perspectiveview. of the casing I member (on a somewhat smallerscale).
Fig. 4: is a rear elevation of thedoor. c Fig. 5 s a rear elevation of the door frame,
sl1owing,the .d0or engaged therewith and )artiall o Jened. l y 1 Fig; 6 is a perspective: view of a "portion assembled, with the door closed;
of the front of the door and frame when The incinerator -(the upper entranceato which is indicated at 1) is loeatedin thevbasementof the building. ,A chute 2 leading down through the building permits the dumping of materials from each floor into the incinerator. The upper end of this chute communicates with a suitableiflue or-ch ms ney. A separate back-flue 3 providesa separate-free passagefor smoke and gases,,and
eliminates any choking or back firing due to the possible obstruction of the inner .flue
and advantages of this invention will be more apparent tions ofthe face ll oficasing ,4. Theup'per the downwardly inclined bottom wall 8 of metallic frame or casing 4 (shown in" perspective in Fig. 3), usually made of cast iron, is embedded or built into'the side wall of the building' This frame is open at its front and rear and serves as a lining for the wall opening, and also as asupport for the doorv and door frame hereinafter described. Casing 4 preferably comprises vertical side walls 5 and 6, a horizontal top wall 7, and a downwardly and inwardly sloping bottom',
one adjacent each lower corner of the easing. will hereafterfbe apparent, these fingersmight be connected together in the form of single forwardly projecting rib or fiange,fbut it is convenient toremove the central portion ofv this 'rib, thus saving jweight-and material; 0 I
Thedoor frame; 14; is in the form a rectangular member with a similarly shaped,
/ central opening, the rear faces of the top bar 15 and side- bars 16 and 17 being adapted to fit snugly against thecorresponding porrear edge of the lowercross bar 18 is provided with a rearwardly and downwardly projecting fiange19lada ted to hook over and fit snugly against .t 'enpper .edge of casing 4. {This hooked engagement serves 1 to hold the bottom'of the door frame 14 in place, and-fits upper corners are providedv with screw orbolt holes, 20 adapted re-g ister with similar openings 21in the casing 4, thus holding the 'twojmembers rigidly,"
togetherpf Theifront face of thejframe l l l isrecessed asindicated at'22'to house'the fpivoteddoor 23 ,1 so-th'at when the-dooris, p closed the front; faces of the door; and frame will be substantially flush with one another. When the door 23 is closed it covers the fastening means which have been passed through holes 20, so that there are no visible means by which the frame 1 1 is attached. to the wall. The lower portion of the transverse bar 18 of the frame, below the in wardly projecting flange 19, is formed with a transverse groove or channel 24: which opens rearwardly, and the ends of this channeled portion 2 1 terminate short of the sides of the frame so as to leave open notches 25 between the ends of this channeicd portion and the side ribs 26 of the frame. These notches 25 are open at the front, rear and. bottom of the frame, but closed at the top.
The one-piece metal. door may have a substantially smooth and unbroken front surface, although it is here shown as formed with a slightly depressed central panel 27, merely for ornamental purposes. On its rear face the door is formed with a rearwardly projecting side rib 28 extending around the four sides of the door and adaptedto fit snugly against the recessed surface 22 of the door frame 1%. The door is also formed with a pair of vertical rearwardly projectingfianges 29 near its side edges, to which the hopper 30, hereinafter described, is-attached. At its lower corners the door is formed with a pair of downwardly projecting, substantially cylindrical lugs 31 which are adapted to fit snugly within the notches 25 in the door frame. Hinge pins 32 project inwardly toward one another from these lugs 31. Preferably, these hinge pins are pieces of steel rod which are cast into the lugs 31 when the door is formed. A handle 33 is secured to the upper front portion of door 23 by means of screws 3 1 passed through" the door from the fear and engaging with the posts of the handle.
To assemble this device, the lugs 31 and pivot pins 32 are hooked into the notches 25 and channel '24 of frame 1 1, from the bottom and rear and then the door is swung up into closed position. This assembly is then engaged with the casing i by hooking the lip, or flange 19 on frame 1 1- over the upper edge of the bottom wall of the casing, and then inserting the screws or other fastening devices through the mating holes 20 and 21 in the door frame and casing. The lugs or fingers 13 will automatically be projected into the channel 2 1 against the rear or exposed sides of the pivot pins 32 so as to prevent these pins from. slipping rearwardly. It will be noted that the pivot pins are now confined on all sides. so that the door 23 may be swung about these pins as a pivotal axis. When the door is in its. closed position, it will incline sli htly in wardly' (see Fig. 2) at its upper'enc. so as to be heldin' this closed position'by itsown weight. The weight v,of the hopper 30,
which is secured to the flanges 29 on the rear of the door, also tends to hold the door closed. When. the door is swung to the open position as shown in dottedlines at the top of Fig. 1, the garbage or other refuse may be placed in the hopper 30 and when the door is swung to closed position,
thismaterial will automatically be dumped into the chute 2.
It will be noted thatthe only. accessible fastening devices are the screws by which the upper end of frame 1a is secured to the casing, and these screws are covered by the door when this is in closed position. There are no exposed hinge pins or fasteners of any kind at the lower'pivoted edge of the door, and the entire exposed edges and sides of the door frame as wellv as the door are smooth and substantially flush with one another. This permits these surfaces to be continuously coated with a heat-resisting vitreous'enamel, which is preferably selected to match the, other interior decorations of the room, and there are practically-no exthereof for engaging the frame with the cas-' ing; devices at another edge of the door frame and covered by the door when closed, for securing'this edge of the frame to the casing; and elements for hinging the door to the frame arranged on the. inner sides of the door and frame so as to be concealed when the door is closed. 1
2. A closure for incinerator chutes comprising a metallic casing to be placed in the building wall as a lining for the receiving opening, a door frame, a door, there being cooperating hinge portions integralwith the door and frame for pivotally mounting the door in the frame, and means integral with the casing projecting into. on-
gagement with these hinge members to hold the hinge members in assembled relation and prevent disengagement thereof when the frame is mounted on the casing.
3. A closure for incinerator chutes comprising metallic casing to be placed'in the building wall as a lining for the receiv-.
ing opening, a door'fframe, a door, there being integral hinge pins formed on the door, an integral channel formed on the rear of the frame for receiving and coin cealing the hinge pins, and means integral with the casing for holding the pins in place within the channel when the parts are assembled. 4
