LATCH FOR OVEN DOORS.
APPLICATION FILED DEC. 1, 1920.
Patented Apr. 25, 1922.
Specification of Letters Patent;
sir As McCLURE, or BEA ER nemjwisoonsin. 7
Application filed December 1,1920. Serial 427,475.
To all whom it may concern Be it known that I, SILAsMGCLURma citizen of the United States, residing 'atBeaver Dannin the .county of Dodge, Stateof Wiscousin, have invented certain new and useful Improvements in Latches for ()ven- Doors;
and I do hereby. declare the following to be a fulhclear, and.exactdescription of the illvention, such as will enable others-skilled in the art to which it appertains to make and use the same.
Thisinvention relatesto' oven doors, and
has for its object the provision of an lIleX- pensive andxreliab'le latch or fastening which is wholly concealed between the door and the stove when the stove is closed, and which holds the door securely closed and is released by moving the'door bodily in the'plane of the door, and which includes means for releasing the door when undue stress is exerted on the doorin a direction to open the same. A further object of theinvention is toprovide afastening operated'without shock or jar which might injure the contents of the oven.
fication andthe accompanyingdrawing, illustrating the-preferred embodiment, in which g Fig. 1 isia view inelevation of a stove to which my invention is applied; r Fig. 2 is a vertical transverse .section through the catch; and,
Fig. 3 is a section on the line 3-3 'of Fig.2. i 1'. a It is particularly desirable, in gas stoves, to provide a simple and effective fastening forflthe oven door, which will-be automatically released by pressure developed through explosion of accumulated gas in theoven and numerous more or.less clumsy contriv v a-nces have been suggested and used in an fiatt'empt to accomplish the desiredv object;
Gas stoves have reached a high stage of per: fe'ction, and, to meet the demands of a cr1t1- cal public, much attentlon isdirected to. the
, outward appearance of the stove byprogres- Further objects and. advantages of the in} vention will be apparent as It is betterun derstood by reference to the following speciratnt 'uifiir. 25', 192 2. c i
the ovenidoor is closechlihave devised-"the volves theu'se of a knob-which is secured to the stove frame and is provided with 'two preferablyfrusto-con icalfaces, "in cooperation with amemberconcealed within the door frame and 'having an opening through which the knob projects when the door is closed. The parts mentioned are immovable with respect to the stove 'and doorframes terthe opening, the lip at the edge thereof normally providing a secure fastening which holds the door in closed position. As Will-be apparent'th'e parts -'are'.all rigid andtherefore strong and-serviceable. 'The'wei'ght'of the door is sufficient to prevent accidental opening. Thelip, however, engages afrustos present invention; Briefly the'invention 'in- Y 66 upon which they are supported and the door isloosely supported on its hin ges which provid'e sufficient play to permit the knob toenconical surface when force is applied: to the I door to close or open it and riding over this surface lifts the door'the requireddistance without effort by the operator. Force applied by an explosion within the oven im.-
mediately opens the door and seriousdamage tothe stove is prevented. 1
. Referring to the drawing; 5 indicates the body of a stove which in the present instance is a combination coal and gas range although my-invention is obviously not restricted to this particular type of stove An oven-door 6l=is supported on hinges 7 which as above pointed outi-permit-a vertical movement of the door. A- comparatively slight play is sufficient and may be .accomplishedby en a larging the openings-forthe hinge pintles in one ofthe members of each hinge. The door comprises a ehannelshaped-frame 8 preferably of malleable 1ron,-a sheet metal back or lining 9,;anda sheet metal panel 10 which is preferably enameled. A-handle 11 is secured to the 'doorto facilitate. opening andclosing thereof.
at the center of its upper side isa. sheet metal member 12 roughly U-shaped and-havingone arm'riveted as indicatedat 12-, ,or
otherwise fastened, to the' frame 8. The
other arm .is provided "with an opening .13
U' 1 Concealed 'witlnnthe frame 8, preferably which is thusv surrounded by a, lip, adapted.
tofcooperate with a knob 14, on the stove frames;
The knob l l is preferably the form of a rivet having an end 15 which is inserted in a suitable opening provided in an angle iron 16 which is a part of the stove frame. The end 15 has a shoulder which is adapted to bear against the outer surface of the stove, while the rivet is batteredto secure the knob 14 in place. The knob 14 preferably has outer and inner frusto- conical faces 17 and 18 and an intermediate cylindrical portion although the form of the knob may be varied. In closing the door pressure is applied to the handle 11 or the door given sufficient momentum to ensure that the lip above the opening 13 rides up the conical surface 17 anddrops behind the cylindrical portionof the knob, the door being slightly lifted on its hinges during this operation. A pull on the handle causes the lip to similarly ride up the conical surface 18 and drop on the other side of the cylindrical portion of the knob. An explosion within the oven opens the door exactly as if the handle had been pulled.
The simplicity and neatness of the catch is sufficiently obvious. It is easily manufac tured and applied and is, therefore, inexpensive; The oven door is securely held except when opened in the manner described and the parts are of a kind which are not easily damaged even by abusive treatment. These and other advantages of my invention insure its successful and satisfactory use in gas stoves and the like.
.LVarious changes may be made in the form, arrangement and construction of the parts Without departing from the invention or sacrificing any of its attendant advantages.
