Referring now more particularly to the figures of the drawings, wherein there is disclosed one illustrative embodiment exemplifying the principles of the present invention, Figures 1 and 2 disclose a juicing and. whipping appliance comprising a drive assembly l and a supporting It will be seen that the drive motor assembly comprises a motor housing ifi containing a suitable driving motor and a permanently associated rigid supporting bracket assembly I6. From the lowerportion of the housing, projects a pair of drive shafts I8 interengageable with whipping agitators I9 which may extend into a bowl represented by the dotted lines in Figures 1 and 2.

The driving assembly, as shown more clearly in Figures 1, 2, 7 and 9, comprises a housing having an upper dome-shaped shell 20 and a lower concave section 22 providedwith annular side walls and outwardly flanged as at 2li, providing axially facing recesses to receive opposite cornerl margins of the laminated core 26 of the electric drive motor 28. In order to hold the upper and lower shells 20 and 22 axially upon the laminated core 2B in the position shown in Figure 7, there is provided an annular clamping band 30 extending about the angular flanges 26 as shown in the figure, and having radially extending marginal peripheral flanges 32 oppositely embracing the complementary radially extending portions of the flanges 2Q. The flanges 32, being disposed outwardly of the flanges 2li, oppositely embrace the latter, permanently completing the housing assembly.

From the foregoing, it will be apparent that the band 30 embraces the shells in the position f shown, terminating in opposed circumferential extremities 3d projecting radially outwardly in spaced parallel relationship as indicated by the dotted lines in Figure 1.

Attention is directed to the fact that the projecting lugs or extremities 3ft are restrained by Ya pair of complementary brackets 36 conflgurated as show n in Figure and having permanent interlocking engagement with the housing. To this end, each of the brackets comprises a side wall 38 narrowed at its central portion and cut away or relieved as at 6U (see Figure 10) in a recess complementary in form to the clamping band 3B..

' in a complementary aperture or slot (not shown in detail) in one of the shells 2 0 or 22 so that each pair of brackets 36 may merely be clipped into the housing, as shown in Figure 1, after the clamping band is in position and when so arranged will bear a rigid, fixed angular relation Y to the housing, adapted to resist any substantial distortion.l

It will be apparent from the foregoing that with a pair of complementary brackets 36 engaging the housing on opposite sides of the clamping band extremities, the latter are permanently retained in the position shown. The brackets are permanently held in the position shown to tension the extremities of the clamping band by a clamping screw d8 projecting therethrough at aperture 50 and through the lugs 34.

It is though that important simplification of assembly operations will be apparent to those skilled in the art from a careful consideration of the foregoing. Thus, after merely locating the housing shells and clamping band in the position shown, the complementary pair of brackets 36v are shifted and interlocked with the housing by shifting the lugs lil thrbugh the complementary apertures or slots and applying tensioning member 58. It will be appreciated that the recesses or housing slots td receive the lug portions 46 may preferably be somewhat circumferentially elongated within minor limits to facilitate appreciable applica tion of tension through the agency of the clamping fastener 48, It is obvious from the fore going that the present construction eliminates the prior costly and protracted assembly process involving welding and at the same time positively interlocks the bracket and the housing against displacement in any relative direction. It will be appreciated that this is of material importance where the weight of the driving assembly must be supported in nxed angular re-1 lationship While under appreciable load.

As further shown in Figure 10, each of the brackets 36 is provided with an inwardly projecting rigidifying flange 52 limiting the ap proach of the opposed complementary brackets in assembled relation. The opposite or right hand extremity of each of the brackets 35, as viewed in Figure 10, is flared in its plane to provide al1 upper or handle engaging section all apertured as at 55 to receive a handle attach-- ment pin or fastener 58. The handle portion of the driving assembly comprises a manually engageable handle bracket conveniently shaped for manual engagement at its central portion and having its lower extremity extending betweenthevopposed sheet brackets 36 as shown in Figures 1, 3, 4,v 5 and 6. As` clearly shownin these figures, the illustrated fastener 58 com prises a pin and bolt applying a permanent clamping force to rigidly clamp the handle bracket 60 between flange portions 54.

The upper portion of the handle bracket fili has a surface E2 complementarily engaging the dome of the upper surface of the housing shell 20 and fastened by a llster headed fastener i3d.

As clearly shown Ain Figure 7, the fastener en gages the housing at 66 and a Washer 68 below the head of the fastener permits the latter to provide a cylindrical interlocking projection for a purpose which will hereinafter appear more in, detail. From the foregoing it will be obvious that the handle bracket BU has rigid permanent engagement with the motor housing and the sheet brackets 36 provide a rigid unitary assentin bly.

Referring more in detail to Figures 7 and 8, it will be seen that the motor 28 is of conventional forrn disposed centrally and axially of the housing with the drive shaft extending downwardly and bearing at its lower extremity a pinion l0. Pinion 'I0 interengages both of a pair of gears 'l2 fixed to the upper extremities of the shafts i8. The gears 'lil and i2 dise posed within a gear transmission housin' l having a cover 'I6 held in position on the housing by fasteners I8 which also extend through the lower wall of the housing shell 22 for locating the transmission housing I4 within the shell. Projecting sleeves or bushings 80 on the transmission housing extend downwardly about journal portions in the shafts I8 and oil sealing co1- lars 82 on the shafts I9 bear against the lower faces of the bushings 80 to prevent leakage of lubricant from the transmission housing.

The beater or whipper units I9 couple releasably with the lower extremities of the shafts I8 by virtue of suitable coupling means shown in Figures l, 2 and 7 comprising a sleeve 84 rigid with the upper extremity of each beater for embracing the lower end of a stub shaft I8. Each l of these shafts is complementarily relieved on opposite sides of a central axial plane, as clearly shown in Figure '7, for rotational interengagement. In other words, each of the shafts is provided with complementary radial abutment faces for transmitting rotational movement. It should be noted that the beater shaft has a beveled portion 86 to facilitate entry of the stub shaft I8 into the recess formed by the cut away portion. A resilient spring arm 88 fixed to the lower extremity of sleeve 04 extends thereabove and is apertured-to embrace the shaft I8. By virtue of being tensioned in a lateral direction, the shaft embracing portion accordingly tends to interengage in an annular groove 80 in the shaft I8. Accordingly, in the position shown, each beater is axially latched to the shaft while being interlocked against relative rotation and may be readily released by manually shifting the spring latch 88 until its aperture aligns coaxially with shaft I8, when the parts may be axially separated.

Provision is made for efllciently Ventilating the drive motor by means of a fan impeller 92 mounted upon the upper projecting portion of the motor drive shaft. The fan is conflgurated to direct air downwardly wherefore apertures 94 in the upper shell 20 supply a current of air passing downwardly about the motor and exhausting through lower elongated slots or apertures 86. I have particularly noted that in many of the conventional constructions with which I am familiar, the aero-dynamic design is such that the cooling impeller permits the air to circulate inefiiciently about housing portions requiring no cooling.. In other words, there is frequently a.

tendency to induce circulation at points remote from the heated portions of the motor, resulting in ineifectiveness of the cooling system and loss of power. The present invention contemplates the propulsion of all of the cooling air directly against and through the motor. In short, the present construction concentrates the direction of the cooling air to the motor parts which require cooling. To this end. there is provided an inner shell cr' shroud 88, shown in Figures 7, 9 and l1, having annular conical side wall |00 terminating at its lower extremity in an annular shell engaging flange |02 and at its upper extremity in a radially extending flange |04. This cowling or shroud is snugly' received within the lower portion of the dome-shaped shell 20 and embraces the marginal periphery of the fan impeller 92. It will be obvious from the foregoing that the shroud necessitates axially downward flow of all air handled by the fan blade 92 and directs the air axially upon and through the interstices of the motor. While I have provided an aperture |06 for passage of an electrical supply conduit |08, it will be understood that the aperture is relatively restricted and is occupied by the conduit |08 whereby air leakage is prevented. It will be apparent, moreover, from the foregoing that the present construction necessitates axial flow and inhibitsall tendency for the impeller blade to set up radial and peripheral flow of air, whereby the blade efficiently directs all of the air passing successively through apertures 94 and 96 directly against the parts to be cooled. A snap switch |09 is mounted on the upper portion of the housing in convenient location for controlling actuation of the motor.

Referring now to the supporting construction I2, this comprises a at base portion IIO from one side of which extends an upwardly projecting pedestal I2 engageable with the motive drive unit as shown in Figures 1 and 3 to 6. As clearly shown in these figures, this letter means comprises a pin I I 3 permanently horizontally mounted in the upper extremity of the pedestal and having yjournal portions I|4 extending laterally on either side of the pedestal and terminating in headed abutments IIS. The journal portions 4 are adapted to be received in T-shaped slots III in the plate brackets 36 which laterally embrace the upper extremity of the pedestal I I2 on either side thereof. This pin and bracket interengagement provides a fulcrum about which the driving unit is adapted to swing between the position shown in Figure l and that illustrated in Figure 5. These two positions permit the fixture to be arranged selectively Within a mixing bowl as shown in Figure l, or in a relatively remote and elevated position to permit removal of the bowl.

The present invention provides for adjustment of the lowermost position by means of a stop abutment shown more clearly in Figures 3 and 6v and comprising a bar I20`extending between the two bracket members 36 and welded or otherwise fastened rigidly in position in the apertures |22 (see Figure 10), preferably with the extremities of the bar extending laterally outwardly beyond the plates 36 a short distance in view of an object which will hereinafter appear more in detail. It will be noted that the bar |20 is relatively close to the fulcrum pin I3 on the pedestal and the upper end of the pedestal is accordingly cut away as at |24 to permit rotational swinging of the vbar |20 with the remainder of the motor unit. In the lowered position of the motive drive unit, the bar |20 rests against an inclined face |26 of adjustable abutment member |28 shiftable vertically in a. cornplementary recess |30 provided In the pedestal ||2. The abutment bar or shaft |30 is notched as at |32 with a laterally outwardly facing V- shaped groove or notch extending in a direction normal to the axis of the abutment shaft |28 and providing upper and lower inclined surfaces in planes inclined with respect to said axis. Attention is particularly directed to the fact that this notch is normally engaged by the conical extremity I 34 of a set screw I 36 extending horizontally through the upper portion of the pedestal ||2 and threadedly engaged therewith. Since the inclinationof the conical surface |34, where it engages the pin |28, is complementary to the inclination of the adjacent pin surface, it will be seen that the bounding planes of the notch |32 and the conical planar surface |34 form cooperating cam portions which coact to control the elevation Vof the inclined abutment surface |26. In other words, as the adjustment screw |36 is threadedly shifted inwardly of the ment upwardly. When the set screw is shifted 'to the right, as viewed in Figure 3, the pin |28 abutment face |38 defining one extremity of the cut away or relieved portion |24 of the pedestal. Particular attention is directed to the fact that in moving angularly with respect to the fulcrum pin H3, the'T-shaped slot ||8 shifts slightly with respect to the fulcrum pin H3 to vary the relative location thereof.

It will be obvious from the foregoing that this minor shifting of the fulcrum permits an additional movement of the motor housing suicient to locate the center of gravity beyond the right hand side of `a vertica1 plane passing through the pin ||3 and as viewed in Figures 1 and 5.' In otherwords, the coaction of the fixed fulcrum pin |13 and the relatively elongated slot embracing the'pin enables the disposition of the motor housing under stable conditions in the angularly remote position and without necessitating any rundesirable degree of angular movement. That ist say, the present construction contemplates the coincidental shifting of the driving member and its fulcrum point in opposite angular direction whereby they cooperate to shorten the total movement necessary to bring the member into a position of equilibrium.

While the foregoing description concerns the arrangement of the drive unit in one cooperative relationship with the supporting means and particularly sui-table for mixing and whipping, the invention comprehends the fixed disposition of the same unit ina substantially reversed position as indicated in Figures 12 to 18 whereby to facilitate juicing and similar operations. It will be appreciated from the foregoing that by virtue of the T-shaped slot constructions H8 in the pedestal engaging bracket, the driving unit is freely removable from the pedestal and when inverted in the position shown in Figure 12 is adapted to receive a transmission housing |42, together with a' julcing reamer |84 and a juice trough |46. Attention is particularly directed to Figures 12 and 18 indicating the manner in which the projecting lug formed by the filister headed fastener 61| is received within a complement-ary recess |48 in the base ||0 of the supporting unit I2. It will be see'n that this interengagement iixedly locates the driving unit in the plane of the base portion H0. Fixed engagement against relativeA vertical and angular movement is provided by means of a locking clip or bracket |50 shown more in detail in Figures 12 and 16. The bracket |50 includes a pair of parallel side portions |52 joined by a top web portion |54 and having laterally aligned slots |56 to embrace the laterally projecting pin portions ||4 of the pedestal. A pair of aligned apertures |58 receive a cooperating threaded fastener and wing nut |60, operative to yieldably tension the side walls |52 grippingly against the side face of the pedestal ||2 when disposed thereover as shown in Figure 12.

Attention is particularly directed to the configuration of the opposite or left hand extremities of the side webs |52 as viewed in the figures, comprising a shouldered portion embodying a horizontal surface |62 and an angularly disposed pedestal, the conical surface |34 rides along the upper surface of the notch |32 to urge the abutdownwardly extending surface |64. Stated in other words, these two surfaces cooperate to provide complementary recesses for receiving the laterally extending extremities of the pin or bar |20, which extremities have been designated in Figures 12 and 17 by the reference numeral |66. When received by the locking clip as shown in Figure 12, the motor drive unit is effectively restrained from vertical and rearward movement by the abutments |62 and |66. Similarly, all tendency for rotational movement with respect to the point of engagement with the base 0, and as indicated by the arrows in Figure 12, is likewise resisted. Since the bracket'plates 3B are embraced between the side flanges |52 of the clip, 2t will be seen that the unit is held against latera movement.

From the foregoing, it will be apparent that th'e present construction provides a very simple and effective means for rigidly locating the motive unit in the position shown.

There is disclosed in Figures 14 and 15 the general construction of the transmission unit |42, including an outer cylindrical casing |68 having a lower annular flange |10 adapted to embrace a portion of the motor housing shell 22. A central transverse partition |12 Within the housing |68 mounts a pair of vertically extending sleeves |14 for receiving the stub extremities of the drive shafts |8 while the partition |12 rests upon the shaft collars 82. It should be particularly noted that one of the shafts only engages with one gear of a reduction gear train indicated in general by the reference numeral |16 disposed within a cage comprising the partition |12 and an upper partition |18 joined by a plurality of fixed spacer bars |80. The nal gear |82 of the gear train is rigid with a reamer shaft |84 projecting upwardly through a sleeve |86 secured to the upper partition member |18. Accordingly, it will be seen that the entire transmission assembly including the reamer shaft, journal and sleeve comprises a unit axially disposable within the cylindrical housing |68 and held therein by a plurality o8 fiat headed machine screws |88. Thus, it will be" apparent that the fasteners |88 extend througli the upper wall of the housing |68 to engage the, upper partition |18 of the transmission unit. As clearly shown ,in the figures, the non-circular extremity of one of the drive shafts I8 engages the initial pinion of the gear train, whereby the reamer shaft |84 is rotated at a relatively reduced predetermined speed when the motor is actuated. The other shaft I8 rotates idly.

The upper surface of the transmission |42 supports the more or less conventional juice receiving trough |46 containing a strainer |80, and the reamer |44 separably rotates with the shaft |84 by means of a polygonal coupling sleeve |92 fixed to said shaft and received by a complementary recess in the reamer.

From the foregoing, it will be apparent that in use lthe present device may be employed either as a whipper or juicer, with thedrive shaft means projecting either vertically downwardly or upwardly as desired. In the former arrangement, the T-shaped slot ||8 of the supporting bracket is merely disposed over the laterally extending fulcrum pin ||3 of the pedestal when the entire drive unit may be swung about the pivot. The

operator has at his disposal the adjustment screw |36 operable to positively determine the elevation of the whippers or beaters with respect to the bowl, While being enabled to accurately move the entire beating assembly out of the bowl to a remote position of positive stability.

Transition to a form suitable for juicing is effected simply by removing the' driving assembly from the supporting means and inverting it upon the supporting base with a drive shaft extending upwardly, in which position the holding clip |50 is applied to clampingly grip the pedestal and the drive unit bracket. The transmission housing and reamer are freely disposed over the projecting drive shafts to positively connect the reamer in driving relation to one of the shafts. It is evident that in either position of use, the parts are rigidly interlocked and held by the supporting member and thus xedlylocated with respect to the supporting surface.

From the foregoing, it will be evident that the present invention simplifies the construction of appliances of the present class by eliminating the plurality of drive connections conventionally employed to enable a wide variety of adaptations between whipping and juicing. In other Words, the present invention contemplates the utilization of a relatively simple driving unit from which the driving shaft means projects only in one direction. Provision is made to locate the unit bodily in either of a plurality of operative positions with respect to a supporting means which rigidly holds the unit in either position. Accordingly, therefore, I am enabled to employ a driving unit of relatively simplified construction employing a novel degree of compactness, lightnessrand portability.

It will be further apparent that the present invention provides an improved interassembly of housing and supporting bracket parts contributing to a novel rigidity and permanence of the driving unit structure and providing a convenient manual handle by which the drive motor unit may be manipulated when removed from the supporting means. Thus, the present device is adaptable to operation for stirring and agitating while manually held in a manner obviously impractical with less portable devices. Lt should be further noted that the present invienton provides a simplified driving construction involving a motor arranged on a vertical axis and supplied with a predetermined air draft applied directly and (positively through the portions of the motor requiring cooling.

The present invention further provides an improved simplified oil seal construction adapted to retain oil and lubricantwithin the gear chamber. It will be appreciated that in the operation of the present device it is important to effectively prevent passage of this lubricant beyond its housing and into the mixing or whipping zone. To this end, attention is particularly directed to the sealing construction shown-in Figure 7, wherein the projecting sleeves 80 of the transmission housing 14 which embrace the shafts I8 are annularly recessed at their lower end to receive an annular felt washer 20D. While the felt washer thus retained-is effective to resist leakage of oil, I have found that the felt may sometimes become soaked. Accordingly, therefor/e, attention is directed to the fact that the oil sealing collars 82 cooperate to trap the oil within an area or cavity between the collars or cups and the adjacent outer surfaces of the sleeves 80 and to this end each of the collars or cups 82 is provided with a downwardly projecting cylindrical portion 202 embracing and rigid with the associated shaft I8. Accordingly, therefore, the portion 262 makes a tight sealing fit upon the shaft therebetween.

I8. A radial wall of the cup 204 extends outwardly from the lower cylindrical portion 202 and terminates in a vertical cylindrical cup portion 206 about the outer walls of the bushing. It is particularly important to note that the cylindrical walls of the cup arespaced a substantial distance from the bushing providing an appreciable cavity which prevents the oil from creeping and thus effectively retains any excess lubricant within the cup.

Obviously the foregoing construction provides an appliance capable of being rapidly and efficiently assembled by a few simple assembly operations in quantity production.

Obviously the invention is not limited to the specific structural arrangement disclosed herein, but is capable of other modifications and changes without departing from the spirit and scope of the present invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
