Australia Application April 22, 1937, Serial No. 138,448 In Australia July 7, 1936 2 Claims.

My invention relates to cooking utensils of the saucepan type and provides improvements therein whereby the content will not boil over during cooking operations, or overflow when the utensil is tilted to considerable angle. The latter quality renders the invention particularly useful upon marine and air craft.

According hereto the top of a cylindrical saucepan is provided with an integral extension of larger diameter, and has removably supported within it an upwardly projecting baflle resembling in cross section a thin walled truncated cone and having at its upper end a concentric circular opening around which is a ring of perforations, and at its lower end an annular channel having a number of perforations through which liquid flows from the channel back to the saucepan.

A lid which will usually be used for the saucepan has a flange which fits upon the top of the extension while when the utensil is employed under exceptionally severe conditions an emergency lid is used which has a flange fitting into said annular channel. The first mentioned lid is clamped in position by a spring band passing diametrically across it, and bearing upon a handle knob thereof, the endsof the band engaging beneath said extension.

A knob projecting from the underside of the upper lid bears upon a handle of the emergency lid and maintains the latter in position.

An embodiment of my invention is illustrated in the drawing wherein:-

Fig. 1 is a central sectional elevation showing all the above parts assembled.

Fig. 2 a plan of the baflle.

Fig. 3 a fragmentary sectional elevation of part of Fig. 1 drawn to a larger scale.

Fig. 4 'a perspective view of the clamping band. Similar numerals of reference indicate corresponding parts throughout the figures.

Referring first more particularly to Figs. 1 and 3:

The saucepan I has upon its upper end a vertical cylindrical extension 2 of larger diameter, the bottom of which provides a horizontal flange ring 3, upon which is seated the horizontal flange 4, (shown in the plan Fig. 2) of a baffle comprised of a hollow truncated conical body portion 5 having at its upper end a vertical ring 6, and at its lower end a surrounding vertical wall 1 which closely fits within the top of the saucepan and with the lower end of the conical portion produces an annular channel 8.

A number of spaced perforations 9 are provided in the bottom of channel 8 and a ring of smaller perforations I is provided near the upper end of the baflie. An emergency lid II has a vertically inclined annular flange 2| which fits within the wall I of the baflle and a horizontal flange I3 which rests upon flange 4 thereof.

A lid I4 which will generally be used has a flange I5 which rests upon the top of extension 2 and upon its under side has a knob I6 which when the emergency lid II is employed bears upon a handle ll of lid II. A clamping band I8 of spring metal, see particularly Fig. 4, passes diametrically across lid I4 and bears at its middle upon a handle knob I9 of lid I4. The ends of the band are shaped to be sprung over the extension 2 its ends passing beneath the flange ring 3.

A handle is fixed to the body of the saucepan. The surface of the material to be boiled should, when placed in the saucepan, be below 20 the bottom of channel 8. I

When boiling milk, porridge, or other matter having rapid expansion at boiling temperature. both covers are removed, and it will be found that no matter how rapidly the boiling point may be reached the fluid will not boil over the edge of the saucepan but will rise through the openings of the baflle into the relatively large space above and surrounding it and either falls back through said opening or passing into channel 8 a0 is returned, to the saucepan through the perforations 9.

When cooking meat and certain other comestibles which are usually cooked with the lid of the saucepan on, the emergency lid II is dispensed with and lid I4 is employed.

Rapid boiling may then take place without danger of the fluid escaping over the top of extension 2.

Lid I I is shaped to provide an incline 2| which 40 deflects fluid into annular channel 8.

In extreme cases where pitching or rolling of a boat or air craft upon which the saucepan is employed, might cause danger through the saucepan falling from the heating stove, both lids II and I4 are applied and clamped in position by clamping band I8 (see Fig. 4) The knob I6 will then by pressure upon the handle I! of lid II maintain the latter in position.

I claim:-

1. A saucepan, having upon its upper end an extension of larger diameter, a hollow truncated conical baffle Within the extension, having an open top with a surrounding ring of perforations, a perforated channel upon the lower end of the extension of larger diameter, a hollow truncate d conical bafile within the extension, having an open top with a surrounding ring of perforations, a

perforated channel upon the lower end of the baflle, a vertical Wall thereof fitting the upper end of the saucepan, a horizontal flange upon the top of said vertical wall resting upon the bottom of the extension, an emergency lid, a. flange thereof fitting within said vertical wall of the baffle, and having a horizontal flange resting upon the conical hafile within the'extension, having an open ried by said'emergency lid fitting within the vertical wall of the baffle being inclined inwardly so as to deflect fluid within the channel at the lower end of the baflle, and means for holding the flange of the lid within said baffie.

HAROLD TARRANT.
