The invention will now be briefly described. A housing encloses an electric motor and the gearing connections through which are driven the usual mixing tools which are held in suitable clamping devices. The housing is secured by a lo bracket member to a handle which is slidably mounted on an arm, which arm is attached to a horizontal shaft rotatably mounted in the upper part of an upstanding portion of the base. The said base is adapted to support any suitable mixing receptacle. Suitable securing devices attached to the upstanding portion are adapted to hold the said arm in any desired position. When the driving shaft of the motor is extending downwardly, the device may be used for mixing or 20 beating operations. When, however, the motor assembly is moved about the xed axis until the driving shaft extends upwardly, .a reaming tool may take the place of the beating or mixing tool and the device may be used to extract juices or the like. The motor assembly may be removed by the handle from the supporting arm by loosening a suitable locking screw.

The base I is provided with suitable cushion devices 2 upon which it rests. The said base is 30 also provided with one or more downwardly extending bosses 3 in which there are recesses 3a to receive the pin d which is attached to a sup' porting plate 5 with an upturned ilange 5a. The

' said supporting plate may thus be rotated and is 35 adapted to support any suitable mixing recep tacle t. The said base I has a cut-out portion I therein. The inner edge il of said cut-out portion serves as a stop for the arm 9 when said arm is in the position shown in Fig. l5. Integral with 40 the base I is an upstanding post I0 which is provided with a vertical rib portion Il. The said rib portion has a vertical recess I2 which merges into a threaded recess I3 of slightly smaller diameter. Extending horizontally through the recess I3 is a 45 slot I 4, into which the star disks I5, 15a with a spring washer I6 therebetween, are placed. Each of said star disks is provided with a central opening il which has diametrically opposite slots I8.

A bolt 20, having a. lower threaded portion 2| 5o which is adapted to be screwed into the recess I3,

is provided with diametrically opposite vertical ribs 22 which are adapted to extend through and lit closely within the slots I8 in the star disks I5, I5. Thus the ribbed bolt serves as a key to hold 55 30 the lever 38 to the upstanding post I3. The said the disks in iixed relation so that when the disks are turned, the bolt will likewise be rotated. A single start nut i5 may be used in place of the star disks I5 and l5". (See Fig. 18.)

The upstanding post I3 has an aperture -23 in which the shaft 24 is closely fitted. The said shaft is provided with a circumferential groove 25 into which a protruding portion 26 of a screw 21 extends. Thus the shaft is permitted to rotate but cannot have an endwise movement unless the said screw is withdrawn. Adjacent the upstanding post I3 is a disk 26 flxedly mounted on said shaft 24. The said disk is provided with notches 23 on a portion of the circumference. The shaft 24 is also provided with grooves 33, 30* into which are tted the forked ends 3|, 3|* of the arm 3 which has a concave seat portion 32 adapted to rest on the said shaft. The tips of the forked ends 3|, 3| are then clinched to firmly fasten the said arm to the shaft 24. -The disk 28 has a tangentially extending portion 33, the end 34 of which is bent at right angles thereto so that it may rest on the head of the bolt 23, which serves as an adjustable stop. A casing 35 encloses the shaft 24 and is secured thereto. The said casing rotates with the said shaft and is provided with suitable openings through which the arm 3 and the portion 33 extend. The casing is also provided with an aperture 36 above the notched portion of the disk 23. A rivet 31 pivotally supports lever is provided with a thumb portion 33 and a portion 40 which is adapted to t in the notches 23 and so hold the disk 28 and shaft 24 against rotation. An angular portion 4| on the said lever is engaged by a spring 42 secured to the upstanding post I3 by a screw 43 and by the action of the said spring the lever is normally held in engagement with the disk 28.

In Fig. 17 is shown a modied form of the lever 38 in which the angular projection 4|* of the lever engages the spring 42* which is seated in the bracket arm I3 dispensing with the angular proj'ection 4| and the spring 42 shown in Fig. 3 of the drawings.

Slidably mounted on the arm 3 is a handle portion 44 to which is secured a bracket 45. A housing 46 provided with a locking screw 41 is secured to the said bracket. A depressed portion 43 in the arm 3 receives the end of the screw 41 and thus the bracket and handle may be locked inpo- 'sition on the said arm. The bracket 45 supports the electric motor housing 43 to which is secured a gear housing 53 provided with a closing plate 5I 55 which has a flange or collar portion 52 in which are placed the chucks (Figures 12 and 13) which receive and hold the stem 53 of the beating or mixing tool 54. A The clamping device or chuck will now be described in detail as shown in Figures 13 and 14. The sleeve 55 is driven by suitable connections from the motor and the exposed end of said sleeve has pairs `of oppositely positioned cut-out portions 56, 56l at intervals around its circumference, thus permitting the diametrically opposite projections 51, 51* on the stem 53 to fit therein. The said sleeve extends through the closing plate 5| and centrally through the flange portion 52. One end of a clamping spring 58, which encircles the said sleeve, rests upon the closing plate 5|. The other end of said clamping spring presses against the inturned edge 3l* of a conical member 6| to which is securely attached a closing disk 62. The said conical member surrounds the sleeve 55 and encloses a clamplng ball 63 which is loosely held therein. The said spring normally holds the conical member 6| in a position shown in Figure 14. Thus the clamping ball 63 is wedged far enough through the opening 55' in the sleeve 55 so that it will extend into the groove 53 so that the stem cannot be withdrawn. The projections 51, 51 which are fitted within the cut away portions 56, 56n of the sleeve 55 thus lock the said stem so that only rotation of the sleeve will impart rotation to said stem. When it is desired to remove the stem, the closing disk 62 is forced into the flange portion 52". This movement of the closing disk likewise forces in the conical member, so that the clamping ball 60 is released from the groove 53 and the stem may be thus removed.

As shown in Figure 12, the stem 63 of a reaming tool has a flattened guide portion 10 which permits the tool to be withdrawn without forcing the conical member into the flange portion 52. It is apparent that since the machine is in a position as shown in Figure 15 when the reaming tool is used, no clamping action is necessary to prevent the tool from dropping out.

It is obvious from the foregoing description that this utility device may be used for a mixing or beating operation when it is in a position as shown in Figure 1. The bolt 20, which may be raised or lowered by turning the star disks I5, Iii*l provides an adjustable stop for the member 33 so that the angle of the beater stem 53 may be varied at will. When it is desired to remove the receptacle 6, the lever 38 may be swung outwardly by pressing the thumb portion 33 so that the portion 40 becomes disengaged from the notch 23 and then the whole motor assembly may be rotated about the shaft 24 until the height of the beating tool 54 is such that it is above the top of the receptacle 6.

It may be dsirable to use the utility device as a juice extractor,.in which case, the motor assembly is rotated about the shaft 24 to a position as shown in Fig. 15. In this position, the motor and housing 43 are in an inverted position. Of course, the beating or mixing tool 54 is removed from the chuck. A bowl 63, having an upturned fluid diverting wall 64 to which is secured a downwardly extending cup-shaped flange 65, is then placed upon the gear housing 50 so that a pin 52 on the collar member 52 may engage a suitable slot in the downwardly extending flange 65 to prevent rotation of the y said bowl. 'I'he bowl 63 is provided with an outlet 66 to which is secured a suitable spout 51 to direct the extracted juices to some receptacle. A reaming tool 63, having a depending flange 63* extending below the top of said fluid diverting wall 6'4, is provided with a stem 63 which fits in the clamping device or chuck heretofore described.

Then again, it may be desirable to use this utility device as a han'd mixing tool if the receptacle to be used is too large to t on the supporting plate 5. In such a case, the locking screw 41 may be loosened. to permit the entire motor and beater assembly to be withdrawn from the arm 3. The operator may then hold the assembly by the handle 44 and perform the mixing or beating operation in this way.
