at its upper end, is formed .with ahorizontally kklirected fork'oryokefl for accommodating and supporting a swingingly mounted gear casing or housing I5, joinedjwith j an electric motor i6, either Vfor direct current or alternating current,

and the same being adapted for separable connection with any suitable` source of current supe.

ply. The motor ifhas the tr1mnions'i journalledin the arms of the yoke or fork il, so that the casingor housing may be swung in avertical ,direction andk 1s limited in its swinging move-V ment through the medium of stopsl i8k andv S9, vrespectively, ,the stops I 8 being formed on the while the' stop i9 isjformed on 1 Y Vthe motor. It will be'notedthat the motor unit y y uses remains'overhung sub/stantiallyabove.the'center'ofthe base ID so that it .will notv tend'to materially unbalance the 'I'hedetailed arrangement of the rgear drive within the housingy l'forms the subject matter r A oi my companion` application aforesaid and .need not therefore be described Aherein in full detail.

sume@ it top-say :that witmn'the housing 1. arrange aworm screw shaft forming an extenvSion-,of or Vcoupled to a motor driving shaft 2lv f .and comprising a 4coupling terminal 22, representing avhigh; speed drive, projecting without the end -of the housing. 'The yworm-'shaft 20 meshes a large lworm `gearZi 'on a crankshaft-2t extending through opposite sidesrof thehousing l5 Vto provide exposed terminals y and 26 in the sockets `.machine Abybeingshifted from one to Aanother f of its` operating positions.

21 and 28 respectively. The worm shaft 2U also v drives a, small worm gear 30 fast on .an arbor v 3l extending through opposite sides of the housinga'nd providing exposed coupling terminals 3d ce,Y y i -and 35, the latter of which isV centered in a socket 32 carrying a set screwv 33. 'I'hese `terminals `34 and 35 are for the connection of the transmission to appliances to be operated at a greater speed than is available through the gear 23. The hous- Adjustably carried upon the post I3 is a bracket 45 susceptible of horizontal swinging movement and at the free end of-the same is a ball bearing equipped rotatable head 45 constituting a male tting for a female coupling 41 on a bowl rack 48 which, when containing the bowl having contents, is free for rotation so asl to assure a thorough mixing of the contents of the bowl when a mixer appliance 52 is operating within the bowl and driven by the machine,

' `In Fig. 1 of the drawings the casing or housing l5 carries on top a fruit juice extractor ,com-

prising a bowl 49 which ts over the boss 50 (Fig.v

) about the arbor 3 I, and this arbor, through its coupling terminal34, has connection with and drives the juice extractor cone 5I working within the bowl 49. At the lower side of the casing or housing I5 I show the mixer appliance 52 fastened in the under socket 32 and having connection with the arbor 3I to be driven) thereby. These several appliances increase the unbalanced condition of .the motor unit and hold its stop I9 iirmly against the fork I4.

Adapted to be engaged in thesocket 28 is a ilexible connection 53 (Fig. 9) for driving an ice cream freezer or other appliance. i Adapted forconnection with the sleeve-like coupling 43V V(Fig. 9) is the. driven flexible shaft 54 or the churn paddle 55, Fig. 3.

Engageable with the coupling terminal 25 of the up-turned housing I5 (Fig. 6) is the driven 'part of a meat grinder 56, the same being detachably secured in the socket 21.

Engageable with the terminal 22 of the shaft 20 is a tool grinding disk or wheel 51, Fig. '7.

Thus it will be seen that the machine is susceptible of operating many different kinds of appliances, particularly those that have to do with householdV or kitchen purposes orfor farm activities, as for example, churning, and for operating a clothes wringer, washing machine or other contrivance.

In the use of the machine as a churn, of course, it is understood that the bracket 45 is either removed, or shifted out of the way of the` churn body when it is placed upon the base I0, the bracket being in service only in connection with the operation of the machine as a mixer. f

In Fig. 5 of the drawings there is shown a clothes wringer 58 which has its mounting 59 engaged inthe socket 21, and resting upon the base I 0 is a washing machine body 60, while in Fig. 3 the churn body 6I rests upon said base.

In Figs. 1 to 5 the center of gravity of the motor unit is substantially central above the base, with its stop I9 engaged beneath the fork. In this position the unit itself is overbalanced with reference to its trunnions so as to hold itself set in this operating position.

In Fig. 6 the motor drive unit without material change in its center of gravity is swung through an arc of 90 which brings the housing I5 into engagement with aV stop Il on top of the fork I4, and in this position the motor drive unit is unbalanced with-respect to its trunnions in the opposite direction so that it Vwill hold itself set in this position and the unit 56, which it drives, will further unbalance it so it can be held to this operating ,position without being fastened. The motor drive unit is thus adapted to be readily shifted from one to another of its unbalanced of gravity substantially from `a. central overfhanging position above the base and without necessity for anchoring it in any of its operating positions. v

While I have shown my invention inbut one form, it will be obvious to those skilled in the art that itis not so limited, but is susceptible of g variouschanges and'modiflcations, without departing from the spirit thereof,l and I desire,

therefore, that only such ylimitationsshall be placed thereupon as are imposed by the prior art or as are'specifically set forth in the appended claims.

What I claim is:

1. In a household appliance, a base, a standardrising from the margin` oi thebase and having a bracket overhanging the'base, a motor and transmission assembly pivotally mounted on said bracket and having a plurality orf diilerently'disposed power take-of! outlets, coacting stop ele- Y ments von the standard and assembly disposed on the same side of said standard and adapted selectively to be engaged soas to'support said assembly in its various operating'positions in which different power take-oil.' outlets are selectively brought into operative positlon'with relation to difierent'appliancesto Abe driven, the center of gravity of said assembly remaining throughout its operating positions disposed substantially over the center of said base and in position with relation to its` pivotal axisto be held by gravity in any selected operating position.

2. In an appliance of the character described, a base, a stand thereon having offset towards the center of' the base a top bracket arm terminating in a pivot bearing, a motor driven driving mechanism pivoted in said bearing and having a plurality of diiIerently directed power take-off outlets for interchangeable driven appliances, and

'top and bottom. coacting stop elements on said mechanism and stand disposed to limit the swing of the mechanism substantiallyto a 90 arc and present same in different operating positions in which ditlerent power take-olf outlets are selectively brought into operative position for use with ditlerent driven appliances, the bracket arm fbeing elongated and'adapted to lreceive and diinotor unit, a marginal standard rising from said Y base and having a rigidly mounted bearing yoke overhanging the center` of the base, means to pivotally mount the motor unit in said yoke so that its'center of gravity hangsf substantially over the center ofthe base in its various operating positions, and stops on the unit and yoke disposed to be held selectively engaged by the unbalanced condition ofthe motor unit and its driven element in its several operating positions.
