v invention relates to incinerator doors and wis {particularly adapted to, :a type t I door. which has anau-toinatic {closing shield ato prevent gases and smoke from-the ch1m- 6 trey entering into the room. while the door is c-pen or being opened. I This application is a division of my application,iSerial Nam imvasaaa, fiiedoui ae,1924.;.

This icon- .struction provides means whereby when 'the incinerator. door is open to receive the refuse, the rear door means rem-ainswclosed preventing any gases -01"; smoke entering the room into-Which the incineratondoor opens. Upon closing the door the inner closure is opera-ted automatically atwapoint jnstube ifore the closing of the room incinerator door andat ;a time when the refuse receiving scoop doorris' closing very ;rap-idly,,so that the innerdoor is only- =openedrnomentarily andfis operated automatically so that as the scoop door closes in the room, the inner door operates automatically and closes automatically. This is accomplished lever and cam means associated With'the main scoop door of the incineratordoor.

I In the drawings my incinerator or refuse door lis adapted to {he placed in the ohimv-neyE or a residence or building. The incinenator'door'l is adapted to he placed intthe Wall of the building as illustrated in a Figure l with? an opening extending through the wall "into the flue lining of the chimney.

incinerator door I is positioned so that the face plate 30 of the same projects at an angle and isp'ivoted at 182, a handle 31 hein-gplaced at the top or free end of the door of the plate ,39 so that the door plate and door canloe engaged to open into the position illustrated in Figure 2.

This frame work is secured to the chimney in any simple manner and forms the casing: around the opening in the chimney and about the door I.

\Vithin the opening: extending into the chimney I5 tor the door I, I provide it shutt'er door :111 which is pii 'otally secured at 37111111 which 'lorined oi an arcuated form so as to lit over the arcuate edges of the sides El -It. The door 36 is of a width so as to practically close the opening into which the sides of the door I lit in the chimney or opening. and thus the sides of the door 36 rest against tlwarcuated sides of the door I when the door I and the shutter door 36 are in closed position, as illustrated in 11111 lineof liin ure Il. oi the drawings.

The door :36 is adapted to be operated by a lever 38 which is operated by the cam 39 in the closing 1.1peration oi? the door I when the shoulder side of cam 39 comes in contact with the tree end it) of the lever 38.

The lever 38 is pivot-ally connected to the end ot the shaft or pirot point 37 ot' the door Zlti and is formed with a shoulder 4-1 which engages against the shoulder it? when the arm 38 is moved by the closing move- :ment oi? the door I when the cam 39 engages against the free end all) of the same. The arm 38 however, is free to move or lift up ards into the dotted position illustrated in Figure 2 during the opening operation of the door I and when the cam edge of the cam 39 engages under the free end of the lever 38 at the end el-O. This permits the door I to be opened without operating or moving the door 36, the lever 38 lltting up into the dotted position of Figure 2 while the door I opens, and not disturbing the position ot the door 3 The door 36 hangs 11y gravity into closed position illustrated in -full lines in Figure 1. hen the incinerator door I is moved into closed position, from the position illustrated. in Figure 2, the shoulder of the cam 39 engages against the tree end 1110 of the lever 38 and the shoulder ends of the lever 38 and the sleeve of the door 36 which is pivoted to the rod 37, which are. respectively 41 and 42, engage higether and cause the door 36 to he opened by the lever 38. This operation is almost int-sinntancnir'. its the door I allowed to slam shut it operates the door 36 to open the same quickly at the end of the stroke or dosing ot the door I and thus the shutter door is only open i'nomentarily. This permits the grarhage or refuse from the scoop incinerator door I to he quickly discharged -into the chimney flue E. The slammin g' o't' theshutter door 36 which falls into closed position by gravity alter the cam 2'19 has disengaged the tree end l0 ot the lever 38, together with the slannninn ol' the incinerator scoop door I. causes the rel'use in the door I to he 1lischarne1l readily and prcwents it from remaining in the scoop ol? the door I. This adds materially to the practical operatireum's o'l my door and shutter con struction.

It is quite an important feature. of my invention in providing the shutter door 36 which keeps all smoke. and gases out of the room into which the incinerator scoop door I opens. It is not 1'lesiral'1lcto have the gases or smoke troin the chimney flue F1 come out into the room while the incinerator door is open and because this has been true of many other constructions o'l doors, these incinerator doors have been necessarily placed in hallways or other out of the *ay places. This is not necessary with my door as the shutter door keeps the opening closed at all times and until the incenerator scoop door I is practically in closed position. Then when the shutter 36 is opened. it only momentarily so that the tare plate d0 of the door I clo-es the incineintor door opening; almost in'unediatel upon the openi 11g: oi. the shutter 36. I have tonnd this particular door co11- strnction for incinerators to be very desirahle and much preferred over any door where the shutter is not apparent.

In operation and use my door is very simple and the shutter 16 remains closed throughout the entire opening: of the in inerator scoop door I, and as long: as the door I remains in open position the shutter 36 remains closed. completely shuttin; oll the {IRS chamber 01 the line 1 ot the chimney of the room in which the incinerator door I opens. Yet when the door I is moved into closed position the shutter a1; is quickly and eilectively opened to discharge the refuse into the incinerator llne chimney ll This incinerator .tlue chimney F1 is the main line chimney for the incinerator and for the heating plant in most ases where. incinerators are employed and for this reason it will he readily appreciated. that the shutterdoor o l. great importance in my invention. The installations ol my door l are been quite satisfactory in every respect. and apparently are being greatly appreciated in the many places where I have had them installed, so that the effective operation 111 the same is quite complete.

I11 the drawings I have illustrated the lever operating means 38 attached to either side of the door I and opcrahle with the cam 23$) secured to the side plates 33. This causes the ctlectivc operation ot the shutter door 86. It is quite apparent. however, that only one operating means. such no the lever 38. together with the cam 39 and the sl'ionldcrs all and 4-2 are necessary to operate the shutportion of the sides forming saidvdoor passwar 36 when-lit is ofa smallnazture, not being of too heavy a construction. On the larger door it may be more-practical "to use two is of ordinary light. weight construction. The operation is Ivory effective and the incinerator door I gives avery satisfactory The effect of the shutter in much desired and greatly preferred to an incinerator door not having this shutter arrangement. I I I In accordance with the patent statutes I have described the principles ofiop'eration of my incinerator scoop door, and while I have illustrated. a particular formation in the drawings, I desire to have it understood that these are only suggestive as to the carrying out of my invention "and that the invention can be applied to other uses and carried out by other means than, those above set forth within the scope of the following claims.
