' .The presentinvention pertains in general 149,549 filed November 20, 1926, the subject to covers for culinary vessels and moreparticularly to self-basting forroasting pans and the like of the general type disclosed in my Patent No. 1,598,222, dated August 31,1926,

and in my co-pending application, Serial No.

' matter of the presentapplication being divithorough browning of the roast and thGICOVGI V '20 ends may be brought to'a size to permit the sional'of said application.

In accordance with the general features of my present invention I provide a j cover equipped with means for promoting the condensation of the vaporized juices of the roast, and for directingand distributing thejuices evenly over the roast. In addition the cover of the present invention allows the steam to escape'and thereby produces a solution of highly condensated grease which provides a of the present invention is a self-basting cover to such an extent that the attention of a person is not required. V v 7 The cover of the present invention is a relatively thick walled cover and I find that by tapering the apertures through the relatively thick wall ofthe coverthe inner restricted passage of steam but'restrict the passage of the'more viscousfats and at the same time the taper of the apertures forms the condensation pockets within the thickness of the.

objects; and "advantages; of i the Y 7 present invention 'willmore fully ,appear it from the following detailed description taken in connection with the accompanying drawing, in which i V Fig. 1 isa cross sectional view through a cover embodying the present invention; .and

Fig. 2 is a similar view through another trated therein is designated generally by the reference character 10 and is illustrated asa relatively thick walled cover. Where Irefer to relatively thick'walled covers herein, I intendthereby. to distinguish from the relatively thin walled covers well known in the art and commonly formedof sheet metal erally cast or made up in the form of castings but it is to ,be understood that this'may be tion of-the tapered basting apertures with theflthick walled cover. a

' It will be notedthat the cover 10 is illustrated as equipped with a plurality of these tapered apertures 12 which are preferably so spaced from each other and distributed over the cover that a uniform basting action will ;be ,produced thereby. In Fig. 1 the apertures 12 converge downwardly and are confined from end to end within the thickness of the wall of thecover, being disposed within said wall thickness and forming condensation'pockets wholly within said cover wall thickness.

i The restrictedinner ends 13 of the tapered apertures 12 open through-and are disposed at the inner surface of the cover wall and the enlarged outer ends 14 0f said aperture open through and are disposedat the outer surface of said cover wall. In this mannerneither the inner nor outer surfaces ofthe wall of the These relatively thick walled'covers are gen- 2 varied within the scope of the present invention, the gist of which resides in the combina= cover need be provided with depressions or projections with the result that the outer and under surfaces of the coverare relatively smooth and cleaning is facilitated and possibility of scratching the fingers avoided.

The tapered apertures 12'serve as a means for permitting the steam to pass through the cover. Also, these apertures form air vents for the interior of the vessel and serve to pre vent the boiling over of the contents within the roaster or other pan or vessel with which the cover is employed. Still further the apertures 12 promote condensation of the va porized juices of the meats or other food being roastedland the thickness of the wall of the cover in combination with the taper of the apertures forms condensation pockets without additional pocket forming operations, as heretofore. These condensation pockets collect-and distribute the. condensates uniformly over the roast or other food in the vessel with which the cover is used. The thicker the cover wall," obviously the less 'thetaper required to produce condensation pockets of equal size.

The condensation pockets are formed whol- 1y within the thickness of the cover wall, the

size of these condensation pockets beingdependent solely uponthe taper of the apertures a'nd'the thickness of the wall ofthe cover and thesize of'the restricted inner end of each aperturebeing independent of the size of the condensation pocket. The tapering of the apertures 12 also increases the condensing surfaces about said apertures;

- The cover 10 shown in Fig. l is raised at 16 and the top 18, through which the tapered apertures 12 are provided, is shown as being flat, but it is to be understood that this cover may be of semi-spherical or "dome-shaped form or of any other suitable or preferred shape.- Fastened to the central portion of the apertured top wall 18 of the cover 10 is a knob-like handle 20 which may be securedto the'cover as by means of a screw 21 with a washer 22' interposed between the head of the screw and the inner surface ofthe cover. The

cover 10 is also shown as having an annular rim 25 and a downwardly extending annular flange 26. The rim 25 is adapted to rest upon the top of the roasting vessel or the'like the depending flange 26 is adapted to litv down internally therein. It is to be understood, of course,'that the tapered apertures 12 may be arranged in staggered rin g-like formation or otherwise over the entire surface of the. cover to obtain the desired uniform action.

In Fig. 2 I have illustrated another form of the present invention. In this case the cover is designated generally by the reference character 28 and again is a relatively thick, walled cover preferably in the form of a casting. The cover 28'is shown as of semispherical or dome-shaped form'and has an annular-rim 29 and a depending annular flange 30 adapted for cooperation with the roasting vessel. as explained in. connection with the embodiment of Fig. 1. The cover 28 is provided with ahandle 32 which may be fastened thereto similar to the attachment of the handle in theprevious embodiment or otherwise, as desired.

' Formed integral with the inner or under mitting the steam to pass through the cover and form air vents for the interior of the vessel aswell as serving to prevent the boiling over of the contents within the vessel. Furthermore, as before, the apertures promote condensation of the vaporized'juices of the meat or other food being roasted and collect and distribute the condensateuniformly over the roast or the food.

The taper of the apertures 35 is shown as being less pronounced than the taper of the apertures 12 because of the greater thickness provided along the apertures by the depending annular ribs 34 of the embodiment of Fig. 2 than along the apertures in the embodiment of Fig. 1. In the embodiment of Fig. 2, as in the, embodiment of Fig. 1", the taper of the apertures 35 forms the condensation pockets within the thickness of the cover, portion surrounding said apertures and, as before, the enlarged upper ends of the apertures open upwardly to form condensation pockets in the wall of the cover, the size'of these condensation pockets being dependent solely upon the taper and depth of said apertures and theopening of the inner ends of said apertures through thecover being independent of the size of the condensation pockets,

I do not intend to be limited to the precise details shown or described.

I claim:

1. An article of manufacture comprising'a relatively thick walled cover for cooking utensils, means comprising a plurality of apertures formed in the cover wall and opening through said wall for permitting the escape of steam outwardly through the cover and the dripping back of condensation in wardly through the cover. said apertures being enlarged outwardly within the thicknessof the cover wall and having enlarged ends at the outer side ofthe thickness of the cover wall and reduced ends at the inner side of the thickness of said wall, the thickness of the cover wall being sufiicient and the outward enlargement of said apertures such as to form condensation collecting pockets wholly within the thickness ofthe wall of the cover and solely by the outward en largement of said apertures within the thickness of said wall and without bending the wall of the cover in addition to providing steam escape and condensation drip back apertures in order to form condensation collecting pockets adjacent said apertures.

2.- An article of manufacture comprising a casting forming a relatively thick walled cover for cooking utensils, means comprising a plurality of apertures formed in the cover wall and opening through said wall for per mitting the escape of steam outwardly through the cover and the dripping back of condensation inwardly through the cover,
