COOKING UTENSIL.

Specification of Letters Patent.

Patented March 16, 1909.

Application filled March 1G, 1908. Serial No. 420,216.

To all whom it may concern:

Be it known that l, NATHANIEL BALDWIN, a citizen of the United States, residing at lieber city, in the county of 1Vilasatch and s State of Utah, have invented a new and useiiul Cooking Utensil, of which the following is a specification.

This invention relates to cooking utensils. lhe object of the invention is to provide a lo simple and ellicient device of this character which, in operation, may readily be hermetically sealed in order to raise the temperature of the steam above that oi' boiling water in an open vessel, whereby the cooking of the food subjected to the action of the steam will be materially accelerated; in which the pressure of steam may be regulated and automatically controlled, and which may be eme ployed withany one of the various classes of stoves now in general use. i

lith the above and other objects in view,r as will appear' as thenature of the invention is better understood, the same vconsists in the novel construction and combination of parts ol a cooking utensil, as will be hereinafter fully described and claimed.

ln the accompanying drawings forming a part of the specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in vertical section through a utensil constructed in accordf ance with the present invention. Fig. 2 is a top plan view of the utensil. Fig. 3 is a collective detail view, partly in section, of a portion of the cover locking'mechanism. Y

Referring to the drawings, 1 designates a vessel constructed of iron or other suitablematerial, and having its upper edge provided with an upstanding 'liange 2, that is oiiset from the inner wall of the vessel to provide a seat 8 upon which is disposed a packing ring L1 of any suitable material, such as lead. This packing is engaged by the under edgev of the peripheral portion of the cover 5 from4 preferred constructioinand which may be adjusted to maintain anyA desired pressure within the vessel.

he flange 2 is provided with a plurality oi' spaced upstanding lugs S, of which any nun .ber may be employed, siX being shown in the present instance, andeach ol' these lugs is provided with anv oriiice 9. k'The yorifices 9 are engaged by the outerr ends ol a series of levers 10, which, as shown inY Fig. 1, are curved to conform to the upper surface oi' trie cover and bear at their outer end portions upon an upstanding bead 11 formed on the upper side oi' the cover adjacent to its periphery, the bead being preferably curved in cross section in order toy reduce friction between it and the'portions of the levers that coact therewith. The f inner ends of the levers iit in radially disposed seats 12 formed in a disk. 13 that is loosely mounted upon the post, theopposed walls of theseats being provided with recesses 14 that' are disposed in alinement and are engaged by pins 15 carried by the innerends ol' the levers, and by this arrangement the f levers ,will be pivotally connected 4with the disk, and, in order to prevent disconnection of the levers 'from the disk, there is secured to the disk, as by screws 16 extending from the under sidethereoi; la second disk 17 that constitutes the female locking member of the cover, and. is freely slidable upon the post, the oricesthrough the twodisks, as clearly shown in Fig. 1, being of greater diameter than the vthreaded portion oi thepost. The member 17 is provided with an approximately semicircular groovey 18 that is engaged by a 'flange 19 carriedby the male locking member,- the said member compris ing a nut 20 that engages thek threads oi' the post and'is provided with an extension 21 with which is connected a handle v22. As shown in Fig. 8, one wall of the groove 18 is cut away at 23, the object of this arrangement being to permitof ready detachment of the male locking member therefrom when desired, and this is effected by removing the safety valve, turning the handle 22 until the nut 20 is free from engagement withthe. threads of the post, then bodily lifting the cover and male lookin member free of the post, and then latera y withdrawing the male member.

As will be seen by reference to Fig., 1, when the handle 22 is turned about the post as a ilo pivot, the male member 2() will bear upon the female member 21 and thus force the levers downward and outward, and, as they impinge against the bead l1 and the upper Walls of the orifices 9 of the lugs 8, the cover will be forced against the gasket and thereby effect hermetic sealing of the parts.

In order to facilitate handling the utensil, there is a bail 24 provided, which has its terminals pivotally connected with two of the lugs 8 and is furnished with an insulated handle '25.

To provide for cooking two or more kinds of food at one operation, I employ a pair of auxiliary receptacles 26 designed to seat one above the other within the vessel l and havi ing bails or handles 27 which fold downward, the lower vessel being adapted to rest upon a wire or other suitable metallic frame or support 28, whereby a space is maintained in the bottom of the vessel for a supply of water. Under ordinary conditions, only a single auxiliary vessel or food container will be disposed within the vessel 1.

Encircling the vessel is a clamping ring 29 having its ends united by a clamping bolt 30 by which the ring is clamped in place upon the vessel. The ring is adjustable vertically of the vessel and constitutes a bearing or stop by which the entrance of the vessel dovmward in the lid hole of the stove may be limited, when the utensil is employed with an ordinary coal or wood cooking stove.

When the utensil is employed with a gas or gasolene stove, a sheet metal drum or casing 31 is utilized, which is provided at its upper end with an inturned fiange 32, which engages with the underside of the ring 29. The drum is provided adjacent to its upper end with a plurality of escape openings 33, and is of larger diameter than the vessel to provide a chamber around the latter for the reception of the heat and flames from the gas or gasolene which escapes through the openings 33.

The bottom of the vessel is provided with i the usual legs 34 by which it is supported upon the top of an ordinary stove.

From the foregoing description, it will be seen that the utensil is comparatively simple and, in practice, will efficiently perform its functions, and in a safe and reliable manner.

I claim The combination with a vessel provided with orificed lugs, of a cover, a post rigid therewith', a perforated disk mounted upon the post, and being provided with radial slots having their opposed walls provided with seats, a plurality of levers, having their inner ends seated in the slots, and provided with pins to engage the seats, a female locking member secured to the disk, and holding the levers in position; said female member having a semi-circular groove, which member also receives the post, and a male locking member having a threaded engagement with the post, and operating to force the disk downward to secure locking of the cover, said male member having a Harige which slidably engages the groove of the female member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
