1 claim." A(o1. 21e-19) My invention relates to a new and useful improvement in electrically red incinerators, and
has for its object to provide an incinerator inY which the ring of the materialplaced therein will be effected by an electric heating unit so constructed and mounted that it will not only be eifective in ignitingcombustible material placed within the incineratorbut will protect the heating element against damage and from contact with the combustible material before and after A further `object of my invention is to provide an incinerator in the construction of which an outer casing is `utilized and an inner lire resisting lining is so positioned withinthe casing as to `form air spaces between the lining and the casing to prevent undue radiation of heat in order that the incinerator may be used within doors, without danger of causing lire or over heating the room in which it may be located.
A further object of the invention is to so construct such an incinerator that the entire front thereof may be opened to give free andunobstructed access to the interior for cleaning and repairs. n
A still further object of the invention is to provide for connecting the combustion chamber of the incinerator with a chimney ue or other such outlet for the smoke, toprovide draftinlets for bringing about effective combustion of the material placed within the combustion chamber and also to provide for the ready removal of the ashes falling through the grate. f
With these and other ends in View, this invention consists in the details of construction and combination of elements hereinafter set vforth and then specically Adesignated by the claim.
In order that those skilled in the art to which this invention appertains, may understand how 40 to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application; in whichz Fig. 1 is a plan View of my improved incinerator.
Fig. 2 is a front elevation of Fig. 1, partly broken away and sectioned to show the interior construction, heating unit and tilting grate.
Fig. 3 is a central longitudinal section on an enlarged scale of the heating unit as assembled.

ready opening thereof;
Fig.7 is a cross section -on the line 7-7' of Fig. 3. l I
A In carrying. out my invention as herein `em,- bodied, A10 represents a casing', of sheet metal o'r vother suitable materialVprefei-ably rectangular ce in plan and within this casingv is positioned fa lining structure 11 of high heat resistance, the casing being of larger dimensions than the lining structure so asto form the space 12 to prvent the heat from the outer surface of the lining from radiating directly into the room ,where the incinerator is installed and in order that the .temperature of this casing may be kept at aY low point, the space 12 has leading therefrom arfllue 13, said flue surrounding the smoke pipe 14,Y the latter leading from the interior of the combustion chamber while the former leads onlyv from the air space, both being intended for connection with the chimney flue; the lower ends of,the air space being left open or having inlets theretofor 75 supplying free air to said space and causingV a constant circulation of air within the space When the incinerator is heated up. l
15 represents a door which is hinged to the casing by the hinges 16, only one of `which is shown in Fig. 2, and this door is lined with similar material to the lining 11 so that when the door is Aclosed the combustion chamber 17 will beV in condition to receive and hold the material-to be burned andthe lowerportion of the air space will be completed. This door is provided with Ya, latch 18 for engagement with the keeperlg so as to vhold the door in itsclosed position, .butperrnit the 20 represents the charging door which is hinged to the upper portion of 9.0 the casing as 'at 21 and 22, .and this door is also providedvvith a latch 231er holding it closed,
and also carries a lin/ing, here not shown, 'Such lining'bei'ng similai to lining 11 for the saine' purpose.
Thus it Will be seen that free access may be gained to the interior of the incinerator by the opening of the doors 12 and 20.
24 represents what I term as the firing box which is here in the form of a rectangular cast- 100 ing opened at the top and bottom and provided with the flanges 25, which latter rest upon the angle iron frame 26, whereby the box is positioned and supported within the combustion chamber and within this ring box is located the'heating 5105 unit 2'?, said heating unit being composed of a bottom member 28, and a top member 29, the bottom 28 is preferably semi-circular, the two ends extending above the body thereof and having the semi-circular openings 30 therein, and also hav- 'U0 the ashes ing the cross ribs 31 and the flange 32 while the top 29 likewise has the semi-circular openings 33 in the end walls thereof so that when the top is positioned upon the bottom` these semi-circular openings 30 and 33 coincide to form circular openings or holes for the purpose hereinafter explained. The top is also provided witha rib 34 throughl which ac'ircular opening 35 is formed, this last named rib is provided with a flange 36 which serves as a seat for the electrical insulating block 37 one end of said block having a circular hub 38 which fits in the hole 35.
An electrical insulating block 39'is set in the top 29 and positioned by the Ihub 40 thereof passing through the hole formed by the semi-circular openings 30 and 33 and when the top 29 is placed upon the bottom 28, theseblocks rest upon the cross ribs 31 carried by the bottom.
42 is the heating element, the ends of which lare. set in the sockets 43 and there held by the pressure of thel spring 44 vexerted upon the rod 45 through the washer 46 upon which latter, one
vend ofthe spring is seated, the'opposite end of lsaid spring lbeing seated upon 'the electrical jinsulating block 47, the hub of which passes f'through one of -the holes formed by the semicircular openings 30 and 33.y Ilhe rod 45 passes through the Vblocks 37 and 47, its outer end being threaded for the reception of the nuts 48` thereto, for securing the end 'of one lead of the circuit l49 to this rod and the opposite socket 43 is mounted on the conducting rod 50 which [passes throughthe insulating block 39, the outer 'end of said rod being threaded for the reception of the nuts 51 for securing the other lead of the "circuit 49 Yto said rod.
When the heating unit is assembled as has beendescribed, one end thereof is passed through a suitable opening in the firing box 24 until said end also passes through a suitable opening in the opposite wall of l'said box and the flanges 32 and 32a."are brought into contact with the box after which the collar 52 is secured in' place around the two members of the heating unit by the set screw 53 thereby holding the heating unit in position as clearly` shown in Fig. 2.A It being. understood lthat the collar isvpassed over the end ofthe heating unit as the latter isbeing passed in to the firing box.
54"represents a tilting grate which is pivoted at) 55 and 56 within the firing box, the stem 57 'of said grateextending through the lining and casing of the incinerator for the convenient application of the shaker crank 58 and beneath this grate is positioned a sliding ash tray 59 it having a handle 60 for the easy manipulation of said tray and this tray is for the purpose of catching which may fall through the grate or From the foregoing description, the loperation of my improved incinerator will be obviously as follows. Y Y
Refuse material being introduced into the com- Y bustion chamber through the door 20, Vthe time switch 61 is set for the predeterminedpassage.
of the current through the heating element, and this passage of the current will produce sufficient heat within the enclosed heating unit for firing V`this materialthrough the openings 62 assisted by the upward flow of air through the slot 63 which tends to force the heat generated within` said unit through these openings, but said openings are too small to permit a sufficient amount of the refuse to gain access ofthe heating unit to interfere with the operations thereof.
When the contents of the combustion chamber have thus been initially fired, it will continue to 1 burn by thedraft passing upward vthrough the gratev and the smoke and' fumesfrom this combustion will pass through the pipe 14r to the chimney iiue and heating of the lining from this combustion will set up a vigorous circulation of n air within the space 12, the heated air vpassing yoff through the pipe 13`to the chimney flue while fresh air enters at the bottom of said space.v
' I have found in practice that an incinerator installed in a dwelling permitting the burning of old refuse without permittingany smoke or odoi to escape into the building and without givingoif sufficient heat to inconvenience the occupants of said building or in any way increase the fire risk.
Of course, the invention is not to be limited toV the exact details of construction as herein shown, as said structural details may be varied within the limits of the appended claim without departing from the spirit of the invention. Y 1
Having thus fully described my invention; what I claim as new and useful is:'- I
A firing element for `use in an incinerator of the character described, comprising a two part housing, the,y bottom having its ends extended 1 above the body thereof andalso having cross ribs and an air inlet formed therein; thek top being shorter than said bottomy so that the former may be seated between said' extended ends,l said top vbuilt in'accordance with `my' invention lmay be 1 9 also having heat outlet holes and a supporting rib formedtherein.
