HOPER DUUR FOR REFU-SE INCINERATORS. APPLICATION HLEDAU. 1 19H.

frame section a, as shown in Fig. 1, while the screws j in the fiange or lip i, which fits freely into the opening in the frame section n, just below' the top wall thereof, are adapted to he turned up into enga ement with the inclined or beveled under ace of lsaid wall adjacent to its outer edge, thereby securely. adjustably and reniovably fasteniing the frame section b to the permanently set traine section o. This construction affords convenient and effective means for securingr the outer frame section b in which the hop )er door is pivotally mounted or hinged, to t e inner permanently set 'frame section a, with rthe rini fof the outer section bearing snugly against thel chimney face, and allows for variation in the thickness ot the plaster or its projection more or less beyond the outer edge of the frame. sei-tion a, and for inaccuracies in the setting of said frame section.

To prevent cracking ot' the plaster around the door traine as a result of the settling of the chimney or the expansion of the frame due to heat from the chimney flue. the inner frame section av is provided with a yielding plaster-support le, which may extend coniplete.l \l or part way around it adjacent to its outer edge. lt may be conveniently made as shown, ot' a strip of sheet metal fastenedadjacent to its inner edge by bolts or rivets l, to the frame section. and Banged or bent along its unsupported outer edge toward and substantially flush with the outer edge ot' said frame section, which is recessed :is shown iu Fig. l, to receive said flanged or bent. edge and permit said support to yield toward the frame section. and the plaster resting or bearing thereon. to settle or shiftv behind the .overlapping rini or the. frame to expand without cracking the plaster.

A door plate mi, which like the parts or sections of the frame, may be made of cast iron, is horizontally pivoted or hinged adjacent to its lower side to the lower and outer portion of the door janib or seat h. of the frame section b. This may be conveniently accomplished by means of bolts or pins n, threaded in outwardly project ing ears o on the door jamb or seat and journaledl in lug p on the inner side of the door plate, asshown. Thedoorplatemis formed with a backwardly or inwardly curved niarginal flan e or rim, which is fitted to and rests snug y against the jamb or seat g when the door 1s,I closed.

VA hopper g, preferably constructedof a single piece of sheet metal, is attached by bolts or rivets to the back of the door plate m, a sheet r of asbestos board or other suitable insulating material bein interposed between thc outer wall of the hopper'and the door plate, to prevent the heating of said plate and radiation of heat therefrom when 1,297,aeo

farbage or refuse is bein burned in the uriiace or chamber at the iower end of the ehilnne flue.

The inner or back wall of the hopper converging toward the front wall which is attaclied to the door plate m, forms with the parallel and approximately triangular side walls of the hopper a downwardly inclined chute into the chimney flue when the door is closed, as shown b full lines in Fig. 1. When the hopper is tipped forward or outward into receiving position, as indicated by dotted lines in Fig. 1. the inner ed e of the rear wall seats against the top wal of the frame section a and closes the hopper door opeiiin into the room or apartment with which it communicates.

The door plate m is formed along its lower edge to a segment of a cylinder com centi-ie with the axis of the pivot bolts or pins n. and makes a close joint with th lower cross wall or member of the door jamb or seat 'o on the frame member b in any position of the door plate and hopper, as shown in Fig.' 1.

The sheet metal of which the hopper 9 is constructed, is ent. and lapped as shown in Fig. 3, so that while the front wall is severed from the side walls which it overlaps, the back or inner wall is integral withethe side and front walls, and seained joints which tend to rust and break and in which dirt lodges, are thus avoided.

The back or inner wall of the hopper is longer than the front wall or door plate in. in a direction perpendicular to the pivot axis of the hopper, so that when the hopper is tipped forward or out-ward into receiv iupr position. as indicated by dotted lines in Fig. 1, its back or inner wall will extend ohliquely upward across the opening into the chimney line from the outer and lower part of the jamb or seat y o n the frame section b, and by engagement with the inner and upper art. of the frame section a, will arrest and hold the hopper in that position and close the opening into the chimney flue, without obstructing the flue itself, and so that when the hopper is tipped backward or inward into discharging position, as shown by full lines. its back or inner wall will extend obliquel downward to the chimney flue at a sufficient pitch to insure the discharge of the contents of the hopper into the flue.

,The door plate is provided on the outer side .adjacent`to its upper edge with a handle s.

The frame being made in two separate parts or sections a and b, which eanbe easily and quickly assembled and fastened tot-her, admit of first setting the section a in a chimney when it is built or the incinerator is installed therein, and after the building is completed or the chimney is plastered mirage@ 0r finished, nf installing the nnte-r fname tion with the hopper.
