CULINARY UTEN SIL.

Specication of Letters Patent.

Patented Feb. 24, 1920.

Application led February 9, 1918. Serial' No. 216,258.

To au 'whom it may concer/L.'

Be it known that I, SARAH K. ALLIsoN, a citizen of the United States of America, residing at Macomb, in the county of Mc- Donough and State of Illinois, have invented new and useful Improvements in Culinary Utensils, of which the following is a specification.

The invention relates to an improved device for boiling puddings, fruitcakes and the like. It also has the alternative function of an ice cream freezer.

The principal object is to provide a pair of boilers, one being capable of being contained in the other, the two being in spaced relation to each other. The interior boiler is designed to contain the'substance to be boiled or frozen and the outer boiler to contain the water by which the boiling is effected, or to contain the ice by which the freezing is effected. The contents of the inner boiler is thus subjected to a heating or freezing operation without being brought into actual contact with the means for effecting such heating and freezing.

To increase the heating surface of the inner boiler a tubular member is made an integral part thereof, this tubular member connecting with and extending upwardly from the bottom of the inner boller and being closed at its upper end with a -detachable cap. The boiling water can thus enter the tubular member and transfer its heat to the contents of the inner boiler from the center of the latter. Provision is also made for supporting the inner boiler within the outer boiler in such a way that the water may readily pass to the tubular member conjoined with the inner boiler.

Provision is also made for keeping the inner boiler centrally disposed within the outer boiler.

An agitator is provided to be carried within the inner boiler to agitate the contents therein when the device is used for freezing cream, ices and the like.

Various other features will be made to appear as the detail description of the device progresses.

yThe drawings illustrate and the specification describes a particular embodiment of the invention, to which, however. it is not to be restricted. The actual reduction to practice may make manifest certain' desirable changes or alterations and the right is iii .1.

claimed to make any which do not deviatev from the scope of the subjoined claim.

The same numerals of reference designate the saine parts throughout the several figures of the drawings, wherein:

Figure l is a central vertical sectional View through the device.

Fig. 2 is a top plan view with the cover of the outer boiler removed.

Fig. 3 is a section on the line 3 3 of ig. 4 is a perspective View of one form of agitator for use when the invention is being used for freezing purposes.

Fig. 5 is a perspective view of another form of agitator for use within the inner boiler.

Fig. 6 is a sectional view of a double cover to be used in conjunction with the two boilers.

Referring to the drawings, there is shown an outer boiler 1 which for a portion of its height is frusto-conical in shape, the remainder of this boiler being cylindrical in shape.

The inner boiler 2 follows the general shape of the outer boiler but is, of course, smaller than the latter, so that it may sit therein with its walls in spaced relation to the walls of the outer boiler. A tubular member 3 is made integral with the boiler 2 and rises upwardly into the latter from the bottom thereof, the bottom being open where the tubular member 3 connects with it. provided with a plurality of perforations 4 and these perforations may be closed by a cap 5 which screws onto suitable threads formed at the top of the tubular member. The inner boiler 2 is formed with an annular rib 7 for a purpose hereinafter appearing;`

As a means for holding the inner boiler centrally disposed in the outer boiler, there iS provided a support comprising two rings 8 and 9 which are connected by `V-shaped ribs 10. The ring Sconforms to the shape of the inner boiler while the ring 9 conforms to the shape of the outer boiler and the two are of such diameters that they will frictionally engage respectively the outer wall of the inner boiler and the inner wall ofthe outer boiler at appropriate points to hold the bottom of the inner boiler spaced from the bottom of the outer boiler.

The top of the tubular member 3 isbn A cover 11 is provided for .the inner boiler and is adapted to close the open top of the latter, the bottom edge of the cover resting upon the rib 7 and the cover being held in place on the boiler by appropriate clasps 12. A short tubular member 13 connects with the top of the cover 11 and iscentrally disposed thereon. This tubular member is open at both its top and bottom, communicating with the interior of the cover at one end and being closed at the other and by a removable cap 14.

An appropriate bail 15 is attached to the inner boiler to facilitate its removal from the outer boiler. AThere is rovided for the outer boiler 1 a cover 16 w ich rests upon the upper edge of the outer boiler and is held in place thereon by appropriate clasps 17 similar to clasps 12. vThe cover 16 is provided with a. short tubular' member 18 whose lower end opens inside the cover and whose top end carries a cap 19 which is pivotallyattached at one side thereof.

The outer boiler is provided with a. bail 20, to permit its being easily handled.

The tubular members13 and 18 serve ashandles for removing the covers 11 and 16 to which they are respectively connected and aside from this purpose they are rovided to permit the use of the agitator to e later described.

When used to boil puddings and the like, the substance to be boiled is placed in the inner boiler 2. This boiler is then placed in the boiler 1, the support made u of the rings 8 and 9 serving to support this boiler centrally within the outer boiler and spaced from the bottom of the latter. The outer boiler is then supplied with a quantity of water, the cap 5 having been removed to permit the water to rise 1n the tubular member 3 by the expulsion of the air therefrom. After the outer boiler has 'been supplied with water to the required height the ca 5 is replaced. Then the cover 11 is attac ed to the inner boiler b 12, the cap 14 being le on the tubular member 13 of the latter. The attachment of the cover 16 to the outer boiler then places the device in condition to perform its function of cooking the contents of the inner boiler, after the outer boiler has been placed over a re. The heat given off by the water in the outer boiler and in the tubular member 3 serves to effectively cook the contents of the inner boiler.

An a 'tator is provided when it is desired to empy the device for freezing sherbets, ices and the like. This agitator consists of one or more sections each comprisin an outer ring 21 and an inner ring 22 whic are joined together by blades 23. At points ninety degrees apart stout wires 24 are suitably attached to the outer rings 21 and ane means of its clasps parallel to the axes of the rings. The wires 24 are brought together and are united into a whole `by twisting, thus formi a shank 25. This shank 25 is designe to pass through the tubular members 13 and 18 and to receive on its free end a crank 26 which is secured to it by means of an appropriate thumb screw 27. When the device is used as afreezer, the substance to be frozen is placed in the boiler 2 and the agitator placed therein, the inner rings of the agitator sliding loosely over the tubular member 3. The cover 11 is then placed on the inner boiler 2, so that the shank 25 may pass through the tubular member 13 and through the tubular member 18 when the cover 16 is placed on the outer boiler. The clasps of the two covers being used to effect the attachment of the covers to their respective boilers. The cap 14 of the tubular member 13, is of course removed and the cap 19 of the tubular member 18 is shifted out of the way to allow le shank to pass through the tubular memrs.Y

The substance to be frozen having been placed in the inner boiler with the agitator and the space between the inner and outer boilers having been packed with ice-the support comprising the rin 8 and 9 having been removed-the device is ready for the performance of its freezing operation. The rotation of the agitator by means of the crank 26 serves to mix the substance in the inner boiler, while it is being subjected to the freezing property of the ice exterior thereto.

That form of agitator having a crank 26 is provided for use with the invention when it is made in relatively large sizes, but when the two boilers are'made smaller in size, the agitator is modified and arranged in the form shown in Fig. 5. In this modified form there is but one member comprising the rings 21 and 22 and there is supplied in place of the crank 26, a detachable straight handle 28 secured in place by a set screw 29. In the employment of this modified form of agitator, it is designed to be reci rocated and not rotated, as is the case with the agitator shown in Fig. 4.

It is obvious that the two boilers may be made of any suitable material, either galvanized iron, tin, or earthen-ware. The invention may be employed for cooking substances which it is desired to keep from being brought into contact with the water supplying the cooking heat. This is accomplished by having the cover on the inner oiler attached when such substance is being cooked. In cooking cereals and the like, the inner cover may be removed, when the steam from the water in the outer boiler will be brought into contact with the cereal in the inner boiler, to provide a certain amount of moisture for the cereal.

The cap 19 of the tubular member 18 is provided for the purpose of permitting the exit of steam from the outer boiler when the invention is used for cooking cereals, as above mentioned.

In Fig. 6, there is shown a double cover to be used with the two boilers when cooking cereals and the like. This double cover may be used in lieu of the two covers mentioned above for cooking cereals. It comprises a cylindrical section 3l adapted to cover the open top of the inner boiler, this cylindrical section havin an annular flange section 33 with which t e outer cover section 30 is connected. An annular shoulder portion 32 is formed where the cover section adjoins the iange sec-tion 33, and this cover section 30 is provided with an integral annular tubular member 34 having a pivotally mounted cover 35, these two latter being similar to the tubular member 18 and its cap 10 attached to the cover 16. A handle 36 is provided to permit the double cover being removed from or positioned on the two boilers. The flange portion 33 is designed to be perforated in a suitable manner to permit steam from the outer boiler to enter the space within the hollow and doublel cover, this steam escaping from the latter through the tubular member 34 when the cap 35 thereof is opened to permit the exit of such steam.

The double cover is provided for the purpose of furnishing a suitable member for coverin or uncovering both boilers simultaneous y and may be conveniently and economically used when the invention is used for cooking cereals and the like. This double cover, however, is not absolutely necessary, as cereals may be cooked in the inner boiler and the individual covers l1 and 16 used to cover their attendant boilers in place of the double cover just described.

The invention having been described what is new and useful is.

The combination of a pair of boilers, the one being disposed within the other, the two being of inverted frusto-conical shape, and a supporting medium for the inner boiler to hold it spaced from the side walls and bottom of the outer boiler, the said medium consisting of a pair of rings shaped to conform to the shapes of the two boilers respectively, and a plurality of V-shaped ribs uniting the rings, the larger ring engaging the inner surface of the outer boiler and the smaller ring engaging the outer surface of the inner boiler.

In testimony whereof I aflix ni s1 ature.
