Patented May a, 1923.
UNITED STATES v 1,454,836 PATENT; OFFICE.
JOHN T. SLOGOMB, OF CRANSTON,
COMPANY, OF EAST PROVIDENCE, ISLAND.
Application filed August 24, 1921.
To all whom it may concem:
Be it known that I, JOHN T. SLOCOMB, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Steam- Pressure- Cookers, of which the following is a specification.
My invention relates to those steam cookers wherein the steam is retained under pressure, and'more particularly to the closures thereof.
The essentialobjects of my invention are the prevention of cramping in the application or removal of the cover; the protection of the rooved seat of the cover against bending w en accidentally dropped orstruck; to enable an automatic tightening or loosening of the cover while in or out of use reto facilitate the centering of the cover upon the body while being applied: to strengthen the top of the boiler body; and to attain these ends in an inexpensive structure.
To the enumerated ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.
In the. accompanying drawings which form a part of this specification,
Figure 1 is a side elevation of a boiler in which my invention is incorporated,
Figure 2, a transverse central section of the same enlarged, and
Figure 3, an enlarged fragmentary section of the cover and of'the boiler body on a linecorresponding to that of Figure 2.
Like reference characters indicate like parts throughout the views.
In the drawings 5 represents the sidewall of a steam pressure coo er body of any usual preferred construction provided with lateral sockets 7 to pivotally receive the heads or ends 8 of the resilient yoke or bail 9 provided with a'central cavity 10.
The body wall 5 is preferably composed of Monel metal and is-in this case cylindrical in outline. The upper dportion of the wall 5 as at 12 is of increase thicknessto sustain the,strain of the yoke. The. top of the body has an upwardly and inwardly inclined beveled margin 13 upon its outer face,"an upwardly and an outwardly inclined beveled inner margin 14, the latter being formed 5 on an internal annular shoulder 15. The
(body, a' cover comprisin moon rsnanb, nssrcnon 'ro Econom cooxnn 'nnoDE rsnann, A coarona'rron or nnona srnm-rnnssuaia cooxna.

marginal faces, therefore, if extended would converge.
The cover or closure member comprises a top or body portion- 17 having in this instance a socket'18 for a sleeve 19 adjustable by a screw 20 and threaded to a post 21 whose end registers in the cavity 10. The post carries a cross bar 23. The body 17 of the cover is provided with a laterally extending rounded peripheral shoulder 25 mergin into arounded depending interiorly incline shoulder 26. Depending from the body 17 inside the shoulder 26 is an annular lug 28 spaced at its top from the shoulder 26 by an annular recess 30, and projecting below the shoulder 26, and provided with a rounded lower extremity, as at 31. The exterior face of the lug 281s inwardly inclined or beveled, and is adapted to rest against the beveled face 14 of the vessel body. The
rounded or inclined lower inner face of the shoulder 26 is adapted to engage the inclined face 13 of the body portion 15 whose upper edge is adapted to enter the recess 30. The material is preferably aluminum.
The exponent of expansion of Monel metal is less than that of aluminum, and this difference of degree of expansion of the two metals causes the cover to adhere to the body of the cooking ute'nsily more tightly during the cooking period.
The annular shoulder 25 is a protection to the channel 30 as the cover is dropped upon its edge, and the member 28 performs alike function when the cover is droppedhorizontally. The downward extension of t the member 28 below the shoulder 26 serves as an auxiliary guide and centering means for the application of the cover. It is desirable that the shoulder 26 and the lug 28 be used in orderto assure a sufiicient strength to withstand the great pressure brought to bear in this class ofarticles. Mere flanges would not besufiicient for this purpose.
As will be readily understood from Fig ure 3, there is an annular clearance space 7 provided bythe annular recess 30 which in-'- sures that the cover will properly wedgeto the sloping sides of the cooker (seat;
I claim 1. In a steam pressure cooker, a cooker a top, a lateral rounded shoulder upon t 0 top, a rounded depending'shoulder integral with the first shoulder, a depending annular lug provided 11 and spaced from the second shoulder to admit the cooker body therebetween, the 7 parts forming means for Wedgingly' pinching the cover and body together.
7 2. In a steam pressure cooker, a body having beveled cover receiving portions and formed of Monel metal, and an aluminum cover comprising an annular depending shoulder and an adjacent depending lug spaced from each other and forming a space to receive the cover receiving portion of the body.
3. In a steampressurocooker, a body having beveled cover receiving portions, 9. cover msaeae comprising an annular shoulder and an annular lug spaced from each other to receive the body therebetween, said body and cover being composed of metals having different degrees of expansion by heat. 4. in a steam cooker, a body having up-, wardly and oppositely inclined beveled faces, and a cover having an annular recess correspondingly tapered to receive said beveled faces of the body and to leave a clearance space above the upper edge of the beveled portion of the body.
In testimony whereof I have aflixed my signature.
JOHN T. SLOCOMB.
