Specification of Letters Patent.

Patented Mar. 7, 1922.

Application led October 15. 1920. Serial No. 417,174.

To all lc/iom vif may concern lie it known that. l. Timmins lhcuaun llimufrox, a citizen of the United States. residing at Britton. in the, county of ()kla homa and State of Oklahoma. have invented certain new and useful Improvements in Mayonnaise-MiXing Devices; and I do here'- A by declare. the following to be. a full` clear,

and exact description of the invention, such l0 as will enable others skilled in the art to which it apperta-ins to make and use t-he same. reference being had to the accompany-I ing drawings. and to the letters and figures of reference marked thereon, which form a part of this specification.

ln mixing edible dressings, such as mayonnaise. where a vegetable oil. such as olive, or peanut, oil is used, it is desirable to add the oil very carefully and slowly, drop by drop, at first. so that it will mix thoroughly with the other ingredients of the dressing.

lt is the object. therefore, of the present invention` to provide a device for mixing mayonnaise dressing. or the like. provided with means for feeding the oil slowly and drop by drop. insuring a steady feeding. and the making of a nice, smooth mixture, which is so much desired.4

With this object in view the invention resides. generally stated, in a receptacle provided with means for agitating the mixture and with means for feeding the oil into the mixture in the receptacle in graduated quantities; that is to say, drop by drop.

The accompanying'drawing clearly discloses the preferred form of my invention and like reference characters identify corresponding parts in the different views. Briefly described:

Figure 1 is a View in central vert-ical section of a device constructed in accordance with my invention and capable of carrying out the objects in View;

Figure 2 is a fragmentary view in top plan of said device;

Figure 3 is a detached detail view in perspective of the peculiarly shaped lid, or cover, of the receptacle., and

Figure 4f is a central vertical sectional view through a receptacle carrying my agitat-ing means, the peculiar lid. or cover, shown in the other views being removed, and showingr also said receptacle disposed within ay tub containing water.

Referring now in detail to the drawing:

1 designates a receptacle of any suitable form. preferably cylindrical as shown, and provided desir-ably with a cone-shaped bottom 2. which extends upward within the receptacle. (ki-operating with said conical bottoni 2 is an agitating member 3, also formed as a hollow cone and numerously perforated. as shown at 4. s0 that there is an escape of the material being agitated from the lower to the upper faces of said agitator, and vice-versa. Desirably, of course, the base of said cone-shaped agitator 3 is substantially' that of the diameter of the receptacle 1` so that there is a snug fit between said base and side wall of the receptacle. The apex of said cone-shaped agitator 3 is extended to provide a nipple 5, which is provided with a screw-threaded socket for the reception of the correspondingly threaded end of a rod 7, having an eye, or hook, 8 at its opposite end. i

Said rod 7 slidably projects through a lid, or cover, for the receptacle 1, said lid beine peculiarly formed, as will now be describe The lid comprises a. bottom 9. preferably circular and provided with an annular upstanding flange 10, which. in use, bears against the inner surface of the side wall of the receptacle l, as shown clearly in Figure 1- Preferably, the top of the flange 10 is rolled, as shown at 11` and bears upon the 'correspondingly rolled. or curled, upper eX- tremity 12 of the side wall of the receptacle 1. The bottom 9 of the lid is providedwith a plurality of inverted. hollow cone-shaped members 13. These members 13 resemble tunnels and are apertured at their apexes, as shown at 14. It will be noticed that the funnel shaped members 13 are of differing capacities and preferably the apertures 14 are also of differing diameters.

In operation. it will be seen that any one of the funnel-shaped members 13 may be used in pouring the oil into the receptacle 1. As an illustration, the. drawing shows in Figure 1 the operator using the funnel 13 having the largest capacity` and having also the largest aperture 14; consequently', the oil escapes through the aperture 14 of this funnel-shaped member 13 in larger drops and at a more rapid speed than if either one of the other two funnel-shaped members 13 were used. The operator thus has his choice of two or more tunnels, so that he may use his judgment as to how quickly and in what sized drops he desires the oil to pass into the receptatcle l, and thus to the ingredients within said receptacle. The rod 7 may be l'eciproc'ated with one hand and the oil poured into one of the funnels 13 from a bottle held in the operators other hand, the agitator 3 Working the oil into the mixture smoothly.

Figure 4 merely shows the provision of a tub 15, in which my receptacle 1 may be disposed, the top containingv either Warm or cold Water. If the water is Warm, it will remove the frost from the contents of the re- Y ceptacle 1, as in churning butter, or in Inaking cake batter. It will be obvious, of course, that While I have shown in Figure 4 a lid 16 of somewhat conventional form as applied to the receptacle 1, the lid previously i described in connection with Figures 1, 2 and 3 may be used When the receptacle is disposed within a tub 15.

While I have shown the rod 7 as'having of a container and supporting said closure,

in position, a central bossl having an opening to accommodate the stein of an agitating ele- `ment and restrain the flow of liquid, and

conical extensions formed in the under side of said closure, each provided with an orifice,

the orifices of each differing in size from the other.

In testimony whereof I hereuntoaiix my signature. l c
