' structionof oven doors, and especially the FRANK w; R EYnoLDs; or ,M- asnnapmo.

To all whom it may concern :Be itknown that I, FRANK lV. REYNOLDS, a citizen of the United States of America, residing at Mansfield, in the county of Richlandand State of Ohio, havev invented certain new and usefullmprovements in Stove" Doors, of which the following is a specifi-= cation. l The present invention relates to stove doors,'and more particularly to those stove doors wherein an inner partition or lining is provided-in order to more perfectly-break the communlcatlon of the hot airon the in V side, with the cold air on the outsideof the doorx 'lt is well known that in the manu? facture of stove doors and especially oven doors, that .it is very desirable to provide the door with a lining of the character indicated, as the heat radiation through the door is thus greatly reduced with a conse quent saving of heat and fuel. I Another very desirable feature in the contype of oven doors commonly known as drop oven doors, is to have the lining flush with the inside face or edge of the door and so arranged that when the oven is open, the

door will present a perfectly smooth plane surface directly in line with the bottom of the oven, and will therefore serve as ashelf onto which receptacles, such as baking pans, etc., may he slid 'into and from the oven, without the necessity of liftinguor without any. jarring. or jolting of the pans, thus greatly reducing the danger commonly called falling, .in the art of bakingcakes, etc.

-Numerous methods have heretofore been I employed for. se'curing the lining in place, oneof'the most .cornmon-beingby means of throu ghfgoingbolts' or screws which are'usually threaded into bosses provide'd for that purpose on the inner. surface of the door.

These bosses not only materially increase the weightof the dcor,.but the drilling and tapping of the same necessitates considerable labor thus largely augmentingthecost of the completed door. v

The principal object of theupresent 'invention is therefore to provide an improved stove door of the character indicated, Tin. .which the lining and the exposed'edges of the walls ofthe door will form a perfectly" smooth, plane surface, and in which the lin-. ing can be easilygand quickly placed inposi- Ution without the use of screws or bolts, thereby reducingthe weight of thedoor'as well.

as the labor necessary tosecurefhe 1n place, and consequently .the cost of manu- I facturi'ng the completed door.

RThe above and other OlOJGCtS are attained i 6.0 by: the construction and arrangement ofparts hereinafter fullydescribed, andrillus 5;

trated in the accompanying drawings, in

whichi.

Figure 1 isa vertical sect onal elevation of the preferred form of my. improved door.

Fig. Qisai-perspectiVe .view' of the liningformed, ready to be sprung into position in the door. f'Flg; 3 is a perspective" view of i the door, the;usualhingedugs, handle and latch "being omitted. Fig.4 is'a view ofa portion of a; modified formof the lining,

and Fig 5:. is asectionalelevation of the door with the modified form of lining position.

Referringgmore specifically to the j drawing-s, reference numerall indicates a stove door, the walls 2,'back 22," (andother; parts,

no-t shown,) of which may be ofthe ordinary and well known construction. On the inner sides. of the walls 2 I provide a series of lugs 3 and 4, which (as will be seen :in Fig 3) are tapered inwardly andndownwardly from a point near the upper edge of the walls 2, thus forming the shoulders or proections 5. Atfa convenientidistance 'below an imaginary. horizontal line connecting the bottom. surfaces of the; lugs 3' and 4c, and

preferably midway' .between the said lugs, I providera' similar inverted lug '6 forming the'projection 7. WhileIhave shown and describe'dtwo upper lugs 3 and14, and one lowerinverted lug 6 in each; wall 2 of the door,yet itwillbe apparent'that' any eon-;

venient. number: of 'lugs may be used, the

number so used being proportioned .to the size of the door.- A

wardly slprojecting flanges 9, as shown in 7 he lining 8 'spreferablyformed IA; linings is: provided, the down-' I v V t I .thini'sheet metal, and it will therefore beapparentthat, as it is being placed'in position lin the'tdoor, the lower edges 12 ofthe i fianges9' w ill slidably engage theftapered .5 surfaces of the Sandhand the lower v door.

edges 12 will be converged, that is to say,

the door, when the apertures 10 and 11 will.

engage the lugs 3 and 4 respectively, and by reason of the resiliency of the material from which the lining 8 is made, the flanges 9 will diverge or spring outward against the inner surfaces of the walls 2 of the door, as shown in Fig. l, and the projections 5 will thus securely retain the lining in position.

When the lining 8 has been placed in position, as just described, the projections 7 of the lugs 6 will serve as stops to prevent the lining from being forced deeper into the door, and thus a smooth or even surface of the inner side of the completed door is maintained.

It will be noticed by referring to Fig. 2, that the ends 13 of the flanges 9 are cut away at their lower edges 12, that to say they are beveledbaclr from their intersection at the corners 1% to the lower edges 12, and it will be apparent that this is necessary, in caseswhere the flange portions 9 are made the full length and width of the lining, in order that the flanges 9 may properly clear each other at the corners of the door when they are convergedby engagement with the tapered lugs 3 and t while the lining is being placed in position in the In the modification shown in Figs. 4 and 5, the flange portions 9 are formed so as to conform, in their normal position, substantially to the tapered surfaces ofthe lugs 3 and 4. The lower portions of the flanges 9 have provided thereon the laterally projecting rib or flange 15, formed substantially parallel to the body portion 16, and substantially corresponding in width to theprojections 5 of the lugs 3 and 4.

It will be obvious that the manner of placing'the modified form of lining in position in the door is similar tothat of the preferred form hereinbefore described, the only difference being that the lining is held in position ,by the engagement of the upper surface 17 of the flange or rib 15 with the projection 5 of the lugs 3 and 4.

lVhile I have shown and described my invention as applied to a particular form 'of stove door, yet I wish to reserve the right to make such modifications thereln as will properlyfall within pended claims;

Having thus fully described my the scope of the. ap-

invenadjacent the upper edge of the said walls to the said projections, a second series of lateral projections formed below the first mentioned series, and a lining having flanges formed thereon, said flanges having cut away portions at each end thereof, and being provided with a series of apertures adapted to engage the first mentioned series of projections, the lower edge of the said flanges being adapted to engage the said second mentioned series of projections, substantially as, and for the purpose set forth.

2. A stove door comprising a back, side walls and end walls, a plurality of inwardly projecting, tapered lugs on the inner surface of said walls, a lining having flanges formed thereon, said flanges being cut away at each end thereof, and being adapted to engage said lugs, the exposed edges of said walls and the lining forming a smooth plane surface, substantially as described.

3. A stove door comprising a back, side walls and end walls, a seriesof lugs forming lateral projections on the inner surface of said walls, a lining having flanges formed thereon, said flanges being cut away at each end thereof, and being provided with a series of apertures adapted to engage the said projections, the inner surface of said walls and said lining forming a perfectly smooth plane surface, substantially as described.

4. A stovedoor comprising side walls and end walls, a series of lugs forming lateral projections on the inner surface of said walls, the said lugs being tapered from apoint adjacent the upper edge of the said walls to the said projections, a lining having flanges formed thereon, the said flanges being cut away at each end thereof and being provided with a series of apertures adapted to engage the said projections, the said lining and upper edge of said walls forming a smooth plane surface, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.-
