` O'l' m8111111), Omi), A CORPORATION 0F OHIO 0m DOOR OONSTBUUIION Application lled July 23,

This invention relates to a stove construction and particularly to an improved type of oven door construction. In many places the gas suppl available for use in gas stoves is the so-ca ed wet gas, that is, a considerable amount of moisture is liberated as a product of combustion. Inasmuch as the oven walls are often cold when theburner is first lighted, it commonly occurs that the moisture thus liberated condenses on the oven walls and particularly on the door. l In some cases there is a suicient condensation to cause an entirely undesirable amount of water to run out around the edgesof the oven door and cause deterioration ofA the floor varnish or other undesirable effects. 'i l Accordingly, it is the object of this invention to provide an oven door which when closed will prevent the esca e of moisture and retain thesame within t e'oven until the temperature rises to such a point that it is evaporated. A further object is to provide 'a Atrough alon the lower portion of the oven door to catc moisture condensing'on such door and retain the same until it can be evaporated. -Other and morespecilc objects will become ap arent as the description proceeds. In the' rawin Fig. 1 is an elevational view ofl an oven oor according to my invention; Fig. 2 is a vertical section taken through such door and adjacent the stove parts; Fig. 3 is a horizontal section throu h such door and adjacent arts;` and Fig. 4 is a fragmentary detail oY -a modified form showing the attachment of a sealing strip to the oven parts instead of to the door parts.

The portions of the oven with which the v door cooperates are composed of wall mem-v bers connected in any suitable manner to an insulated wall portion 11. -The wall por#A tion 10 preferably takes the form ofa facing strip provided with an angular wall 10'l with which an edge of the door is adapted to cooperate and .shoulders 10h adapted to limit *the door member. s

The door consists of opposed flanged telescopingshells 12 and 13 between which is contained a suitable insulating material 14. Extending along the'top and vertical sides of w'the dooris a continuous'V-shaped sealing' Vedge extends outwardly at an angle andis door and extending between the hinge and angular portion 10A the use of Wet -fuel and to retain the same' iaso. sriai in. 469.974.`

stri 15. This strip has'one of -its edges exten ing between the fiang'es of the telescoping shells 12and l13 and is fastened in such position as by means of rivets 16. The other adapted to form a close sealing contact with the angular portion 10a of the wall member 10. This strip is preferably made of resilient sheet metal. Along the bottom of the bracing members 17 is a. trough-forming sealo ing strip 18 consistin of a resilient V-shaped metallic strip secure between the telescopi y ing iianges of the portions 12 and 13 andforming with the wall 120i the door a troughv to retain moisture condensed on the portion 12. The ends of the strip 18 may be sealed to form a water-retai ing trough by solder or an other suitable infans.

n Fig. 4I have shown a modification in which the sealing strip 20 is attached to the] of the wall 10 as bya rivet 21 and cooperates with the edge of the door to effect a moisture seal as will be obvious from lthe drawing. v- Y While I have shown and described certain illustrative embodiments of my invention I wish it understood that the saine is suscep tible of variationand thatI am limited on y in accordance with .the 'appendedclaims.v

Having thus described my invention', what Iclaimis: V- 1..An oven doorincluding Va trough adjacent the bottom thereof adapted to collect any moisture condensingon such door .due to until the oven reaches a vtemperature-siiil'ient to evaporate it, said trough comprising1 a metal strip extending along ,the bottom e ge of the door and projecting inwardly and. upf wardly therefrom. s. Y

2. An oven door constructionincluding'a l door means and wall means defining an opening within which such door means Ais received and 'a bent, metallic sealing strip'attached'to one of said means and adapted'to coact with said other means to seal said opening against -passage of moisture, said strip serving to collect and retain any moisture which maybeA precipitated on the inside 'ofthe door.' .Y

8. An oven door construction including e disposed 'outside of said shell members and door means and wall means defining an openforming a seal between the edges of said door ing within which such door means is received and said wall means..4 l

In testimony whereof I hereunto aix my and a bent, metallic sealing strip attached to one of said means and adapted to coact with said other means to seal said opening a ainst passage of moisture, said strip bein s aped to provide a trough extending along t e lower edge of the door and proj eeting inwardly and upwardly therefrom so as tocollect `any moisture which may be precipitated upon the inside of the door. y

4. An oven door construction including a door means and wall means defining an opening within which such door means is received and a bent, metallic sealing strip attached to one of said means and shaped to provide a trough extending along the lower inner edge of the door and projecting inwardly and upwardly therefrom. l

5. An oven door including flanged, opposed, sheet-metal shell members telescopin one within the other-and a retrorse, curve generally V-shaped member having one leg interposed between the telescopin and the other outside thereof, the bight portion extendin upwardly and forming with one shell mem er a trough.

6. An oven door including ilanged, opposed, sheet-metal shell members telescopin one within the other and a retrorse, curve Lgenerally V-shaped member having one leg interposed between' .the telescoping flanges and the other and shorter one outside thereof, the bight portion extending upwardly and forming with one shell member a trough.

7. An`A oven door includingilanged, opposed, sheet-metal shell members telescopn one within the other and a retrorse, curv generally V-shaped member having one leg interposed between the "telescoping flanges and the other outside thereofthe bight portion extending. upwardly and -formin with one shell member a trou h, said V-s aped member being resilient and serving as a seal for the bottom of the door in addition to its function as a trough.
