Description
A. G. SHERMAN ET AL STOVE DOOR LATCH Filed Nov. l5, 1923 @ttor um? NUV@ B? l v ALvrN e. sHnni/IAN AND ALBHHTHHAnows,
DETROIT VAPOR sTOvHcoHrANY, or
States, residing at Detroit,
' MICHIGAN.
Application mea November To all whom t may concern.' v
lBe it known that we, ALVIN G. SHERMAN and ALBERT MEADOWS, citizens of the Unlted in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Stove-Door Latches, of which the lfollowing isa specification. y
This invention relates to stove door latches. lin the copending vapplication of Albert Meadows, -is described a form of stove latch, and this application is an .improvement over that form of construction.
llt is the object of this invention to provide a construction that can be more cheaply and eciently manufactured and of such a design that all the parts of the latch can be formed of stampings. Another object of the present invention is to form the latch member so as to carry a roller which contacts with the latch strike so as to form an easily operated door latch. Y
In the drawings: p
Fig. 1 is a front `elevation of a gas stove.
Fig. 2 is a vertical section through the latch, and adjacent stove parts, taken on the line 2 2 of Fig. 1.
Fig. 3 is an elevation of the latch and fragmentaryportion of the oven door looking at the same from the inside:
Fig. 4 is a section on the line 4--4 of Fi Fig. 5 is a detail in perspective of the bell crank lever.
y '.lhe standard gas oven consists of the stove 'l top a, and the fro b of pressed steel, which has the bolts wel ed to the ,inside of the frame as at c so that the front and top may be assembled together in a way to conceal the presence of the bolts. A reinforcing strip dis secured on the inside of the stove Serial No. 575,347, there' 0F DETROIT, MICHIGAN, ASS-IG-NORS T0 DETROIT, MICHIGAN, A COPORATION OF sTovn-noon LATCH.
15, 1923. Serial No. 674,894.
inside thereof. The inside lining y' is cut away as at k.
The latch housing n is formed with a hollow bossed porton o and the knuckle eyes p. A pin g is supported by these knuckle eyes and supports the stamping 7', which forms a bell-crank lever carrying a roller s at one end and the other bell-crank lever projecting within the boss o of the latch housing.` A leaf spring t is bolted to the latch housing and bears against the end of the bell-crank lever 1" which eX- end of the (Y tends within the housing. This beu-crank glever, as will be seen from Figs. 3 and 5,
is bent substantially in the leaf spring t bearing portion .or closed end of the U, and tending to force the roll striker .upwardly against the latch strike g so as to retain the door in4 a closed position.
v'llh'e sides of the latch housing or case are slotted as at u and the screws c are threaded into the suitable bosses lw carried by the door frame. In this way, a suitable adjustment of the housing may be had by loosenin the screws o and moving the housing up or down thereby positioning the roll striker in the correct position.
The wall of the boss acts as a stop to limit the outward movement of the latch when the same is not engaged with the latch strike g.
The stamping 7' is so arranged that when the same is bent into the form of a U, it provides the ears through which the stud for supporting the roller strike s passes. 's provides ajsuitable bearing fort supporting the roller on both sides. The bottom' or lclosed end of the lll-shaped bell crank lever' is notched as aty, and the "free end of the leaf spring t is adapted to engage within this notched portion for the purpose of forcing the roll striker into the socket g.
the form of a U, against the bottom and the nuts` e are run on the -bolts to bind Th the top,
front and reinforcing strip together.
in rig. 2 a'wiu be noticed that the steelfront b of the oven dooristurned inwardly and is joined to the top wall f of the oven proper. A portionlof this top wall f 4is struck up as atfg-to form a latch strike. @bviously as a separate member and welded or other? wise secured to the stove frame. is made up of aframe h having secured a vpanel el on the outside and a lining j on the this .latch strike could be formed- The dooie:-
v le spring bearingagainst the lever and engaged within the notched .portion will prevent the bell-crank lever from sidewise MMI' movement, since the eyelets `which support the pivot bearing are necessarily constructed so as to allow plenty of` clearance and the parts would `be inclinedto 4.rattle if it were not for the'spring #exerting pressure on the lever.
at we claim is: l
1. lln a stove door latch construction, the v com, ination.o f a stove frame provided with a llatch strike, a door hingedly suppor Mld by said frame, a housing secured to the door, a bell `crank latch member U-shaped in cross section and pivotally supported by the housing, one end of which is provided with a striker portion, and a leaf spring ar ranged to bear against the other end of the bell-shaped latch member to force the striker portion into the latch strike.
2. In a stove door latch construction, the combination of a stove frame provided with a latch strike, a door hingedly supported by said frame, a housing secured to the door and provided with a raised portion forming a hollow boss, a bell-crank type of latch member U-shaped in cross section pivoted to the housing, the open end of said U-shaped bell crank projecting from the housing and provided with a roll striker on the extreme end thereof, the closed end of the U-shaped bell crank projecting within the hollow boss portion of the housing, and a spring carried by the housing and adapted to bear against :wienerV the closed end of the U-shaped bell crank thereby tending to force the roll striker into the latch strike.
3. In a stove door latch construction, the combination of a stove frame provided with a latch strike, a door hingedly supported by said frame, a housing secured to the door provided with a raised portion forming a hollow boss, a bell-crank type of latch member U-shaped in cross section pivoted to the housing, the open end of said U-shaped bell crank provided with a striker, the closed end of same provided with a notched-out portion, and a leaf spring secured to the housing, the free end of which is adapted to engage in said notch carried by the bell crank lever to force the striker into the latch strike.
In testimony whereof they have aixed their signatures.
