2 Claims.

This invention relates to household mixers and more particularly to combined mixers and juice extractors in which motor-driven agitators or heaters are arranged to extend down into an un- 45 derlying receptacle, and wherein a juice-extracting reamer'and bowl are located above the agitators.-

In devices of this class there have been employed base structures having a turntable there- 10 on for mounting a large mixing bowl. When the turntable of this mixing bowl was set in a certain socket provided in the base the agitators or beaters were located eccentrically of the bowl, and when the turntable was set in another socket 15 provided in the base the heaters were located substantially at the center of the bowl.

One of the objects of my invention is to increase the scope and range of utility of devices of this general class.

20 More particularly my object is to provide a household mixer which will mix, stir or Whip materials when the latter are held in any of a considerable variety of receptacles and which will dc;-

liver extracted juice to any of a considerable va- 25 riety of receptacles.

I contemplate the provision of a mixer or household utility device in which a-number of receptacles difiering in size and shape can be successfully used with the device in addition to a special mixing bowl, and I provide a construction likewise in which it is possible to deliver orange juice from the juice bowl directly into any one of a number of different receptacles standing on the table on which the mixing device stands.

Another object which I have in view is the provision of a mixer which can be used very conveniently, and in which it is possible to locate the agitators or heaters in any of a large number of different positions in the mixing bowl or other receptacle, as may be most convenient and desirable.

To these and other ends the invention consists in: the hovel features and combinations of parts 45 to be hereinafter described and claimed.

In the accompanying drawings: Fig. 1 is an end elevation of a mixer construcmd in accordance with my invention showing the same .as arranged for mixing the contents of a 50 mixing bowl, the bowl and the support therefor being shown in vertical section;

Fig. 2 is a side elevation of the device shown in Fig. l; Fig. 3 is a top plan view, the mixing bowl-and 55 its support being indicated in dotted lines;

Fig. 4 is a perspective view of the adjustable bowl support;

Fig. 5 is a fragmentary sectional view showing the swivel mounting of the motor bracket;

Figs. 6 and 7 are horizontal sectional views on a .5 somewhat smaller scale than Fig. 3, showing different adjustments of the heaters in the mixing bowl; 4

Fig. 8 is a side elevation on a small scale illustrating the employment of a tall and narrow receptacle for mixing;

Fig. 9 is a top plan view of the parts shown in Fig. 8; and r Figs. 10 and 11 are a side elevation and a top plan view, respectively, showing the use of a 15 large pitcher for receivingjuice from the juice bowl.

In its general features my improved household mixer as illustrated herein comprises a base A;

a pedestal B rising therefrom at one end; a bracket C pivoted on the upper end of the pedestal to swing up and down; a motor member D carried by bracket C; a pair of depending oppositely rotating agitators E driven from the motor D by suitable gearing and arranged to project down into a mixing bowl F; a juice reamer G at the upper part of the device driven from motor D; and a juice bowl H supported on the motor member and surrounding the reamer G. The motor bracket C is pivoted on the pedestal B by a pin It, the arrangement being suchthat the agitators E can be swung into and out of bowl F. The juice bowl H is removably mounted on the motor member, and when the motor member is to be swung upwardly from the position shown in Fig. 2 the bowl is removed. The pivot I5 is mounted on a swivel base or platform it having a trunnion li extending down into the open upper end of pedestal B. A screw it extending through the wall of the hollow pedestal at its upperflportion extends into a'groove IS in the trunnion I! and, presses against the bottom of the groove in such a manner as to create a certain amount of friction and thereby prevent the motor bracket from having too free a movement in its socket. By the arrangement described the motor bracket is swiveled for movement in a horizontal plane, and when the motor bracket has been shifted to a definite angular location it will rriaintain that location in spite of slight jarring or vibraticnto which the device may be subjected.

The agitators E are driven from the motor of motor member Dby gearing of known construction, which I have indicated by dotted lines at I in Fig. 2, this gearing being housed in a gear case I. The agitators are removably held in any convenient manner in a socket member J of any approved type. The juice reamer G is driven by a vertical shaft 20 extending upwardly from gearing I, shaft 20 being located in. a sleeve 2|. The bowl H is seated on top of the sleeve 2|. The bowl H is provided with a suitable discharge spout 22, which may be short and may extend straight down from the peripheral portion of the bowl, as illustrated, although this is not essential.

In accordance with the usual practice previous to my invention, the mixing bowl is mounted on a suitable turntable, such as shown at 23, so that the bowl is free for rotation, and the turntable has a laterally fixed mounting in the base of the device. The base of the device has heretofore in most cases extended integrally from the pedestal into and across the space beneath the agitators. Such a structure, however, has been open to a number of objections, among which may be; noted the dimculty or impossibility'of positioning other receptacles than the special mixing bowl, especial-- ly tall receptacles, under the agitators, and the difficulty or impossibility of so positioning ordienary receptacles that they would receive juice.

from the juice bowl. According to my present invention, I overcome these disadvantages and attain a number of new advantages by providing a structure in which the support for the turntable is insertable into and removable from the space beneath the agitators, and is adjustable in that space in a horizontal direction so that when the motor bracket has a swivel mounting as above described the agitators can be located in any of a large number of differentpositions in the receptacle, as may be desired. While this idea may be carried into practice in a number of diiferent ways, I prefer to form the base A as a fork having arms 24 between which may be set a bowl support 25 constituted by a flat heavy member, preferably of metal. I prefer to form the support 25 as a round fiat member or disk having a central socket 26 to receive the spindle 21 of turntable 23. The

disk 2 5 usually has a diameter approximating that of the turntable, although preferably it will be slightly smaller in diameter than the turntable, as shown. The arms 24 of the fork structure at the base of the device are rather widely spaced apart, and these arms are preferably but not necessarily integral with the base portion of pedestal B. The arms 24are relatively short and their end portions are substantially parallel to each other, and they curve toward each other and toward the pedestal in the manner shown in Fig. 3 so as to provide a rounded recess for 'receiving the bowl support 25. The bowl support is received between the arms 24 with a certain amount of clearance at the sides of the bowl support, as shown in Fig. 3, and this permits some lateral adjustment, but it will be understood that longitudinally of the mixer structure the bowl support is capable of considerable adjustment and may be adjusted into a number of different positions, as may be desired.

In Fig. 3 I have'shown in full lines the position of the motor member D when it is in-line with the longitudinal axis of the mixer, and I have indicated in dotted lines the position of the mixing bowl F when the bowl support 25 is set in as far as possible between the arms 24 of the base. It will be observed that when the parts are in this position the agitators E will be located approxiing, the agitators can be moved toward the periphery of the bowl. In Fig. 3'the position of the motor member when swung somewhat to the left is indicated in dotted lines, and the position of the agitators when the motor member is so 5 swung is indicated in dotted lines. When the parts are in this position and the bowl F contains aliquid or semi-liquid, the rotation of the agitators in the material causes the bowl to be re volved in the direction shown by the arrow at the left of Fig. 3. When the agitators are swung to the opposite side of the center line the bowl is caused to rotate in the opposite direction.

In Fig. 6 I have shown the position of the agitators in the bowl when the bowl support is 15 Figs. 8 and 9 show the use of the appliance for 5 mixing the contents of a receptacle which is quite tall. and could not be used so conveniently in connection with mixers having bowl supports of the type heretofore employed. In this case the bowl support 2 5 is withdrawn from the base of the device, and this enables the tall glass or receptacle 21 to be placed on the table between the arms 24. It will be apparent that this receptacle 2! may be adjusted longitudinally of the device to bring it into the desired position. Figs. 10 and 1f show the device as it appears when the agitators are removed from their sockets and when a large pitcher is set in beneath the juice bowl to receive juice therefrom. It will be observed that in this case the base of the pitcher enters the space between the extremities of the arms 24. Such a re- .ceptacle could not be employed for receiving Juice In the case shown in Figs. 10 and 11, for example,

the juice can drop vertically from the spout 22 without the necessity of employing a special tip to direct it laterally. a 5

Various changes in the details of the structure may-be made without departing from the principles of my invention. While I have described only a single embodiment it will be understood that the invention is capable of many different embodiments without departing from the scope of my invention as defined in the claims.

What I claim is:

1. A mixing device comprising a pedestal, a motor supported on the' pedestal for swinging movement upwardly and downwardly, depending agitators associated with the motor, a base for the pedestal having a cut-away portion under lying the agitators so that a receptacle located beneath the agitators can be supported directly on the table, a separate bowl-supporting turntable, and a separate support for said turntable insertable into and removable from the cut-away portion of the base and adapted to stand on the table at least partly within the lines of the base,

cut-away portion in a horizontal plane, and said cut-away portion of the base being shaped to conform generally to said separate support to assist in positioning the same.

2. In a device such as described, the combination of a base, a. pedestal rising from the base adjacent one end thereof, a member swiveled in the upper end portion of the pedestal to swing in a horizontal plane, a. bracket pivoted to saidmember to swing up and down, a motor carried by the bracket, duplex heaters depending from and driven by the motor, said base at the end opposite the pedestal having a fork-shaped portion beneath the heaters so that a receptacle into which the boaters extend can be placed on the table between the arms of the fork, a separate bowl-supporting member adapted to be placed on the table be tween the arms of the fork-shaped portion, saio. bowl-supporting member comprising a disk-like member having an opening therein and a turntable having a spindle extending into said ope-m ing, and said disk-like member being adjustable between the arms of the fork-shaped portion in a horizontai plane.
