'This'invention relates to a'machinelrfor eiect-` ingoperations in a kitchen, such asY kneading, r'nixing, grinding and thelike, al1-example of `such type of machine being foundin Uf. S;"Pat'ent No. 2,270,164; dated Januar-5131942( Thefpresent invention has referencev tomeans by Vvwhichamachineof Ithis character-may be supported-in two positions 'to permit Vof its voperation-while in either position According to the present invention, the machine includes a standard Vin whicha pivotal arm is mounted, said pivotal 'arm'fcarryinga worktoolsuch as a=rol1er, and means Vis providedby which ythe-pivotal arm can be locked linfdiierent positions lof angular adjustment, said means includingaiockingmember whichwill act -as a supporting-foot for the machine whenth'e machineV is disposed in one of its operative-positions;

Another objectof the invention is to provide,

in amachine of this character,supportingelements or feet, arranged in groups andintended for the support of the machne-ineither of two positions, oneI of the feetfinone'ofg they groups being "composed of a locking element for a mov'- able arm of the machine, means being provided for 'normally swinging the-'arm to a'l position whereby said locking element is so disposed so that it can perform its supporting function;` The invention further contemplates the arrangement of a locking means Vforsaid swinging armby means of ywhich thearrn maybe movedto any selected position` withinits range ofswinging movement and maintained in such! position.'`

In the .accompanying drawing, ywhereinganjillustrative embodiment l.ofv the .invention is disclosed:

Two'corresponding `feet I8 are arranged on the side of the motor frame or housing- I 0 fandfco@ operate with a `supporting .foot lI9 arrangedliao# cording 'to` the invention,` at lthe upper or. outer end of. the pillar or `standard IIV,.- in supporting the machine in` its' reclining 'position or vthat shown in Fig.. 1.

Between the pin extension I-B andthe pillar. on standard! I is arranged a torsion spring vZITWhi'oh constantly tendstoturn the-arm laway -from thecenter of the driving shaft I3 into the end position, shownin full line-s inFi'g. 2. lli/"herria4 screwed into the -pinV extensionv i521 I'he-end'sur faces 24 and 25 of the slot zsractfasstopsjorabut; mentsto limit 4the pivotalmovementnoilitlie arm` I5.y

The portion of the bolt 22 which projects beyond the slot 23 is threaded as shown in Fig. 2, and this threaded portion of the bolt 22 adjustably receives a nut 26, preferably formed as a cap nut and which constitutes the supporting foot I9 while at the same time serving as a locking means for the arm I5. To facilitate the manipulation of the nut 26, it is preferably knurled or milled as indicated at 2|. The outer end of the nut is preferably provided with a sole piece 21 or the like, of rubber or other similar soft material which is held in position by means of a screw 29 and interposed washer 28.

When the nut 26 is to serve as a locking device for the arm l5, said nut and an interposed friction washer 30, cooperate with a curved face 3| arranged on the pillar or standard l l outside of and adjacent to the slot 23. Between the outer end of the bolt 22 and the 'oase of the cap` nut 26 is provided a compression spring 32 which prevents the nut from being loosened unintentionally.

From the foregoing, the operation of the described structure will be readily understood. By loosening the nut 25, the arm l may be swung to any desired angular position within the limits of the slot 23, such as, for example, to the position shown in dotted lines in Fig. 2, and the arm is then maintained in such position by tightening the nut 26. By again loosening the nut, the torsional spring 2li will operate to return the arm to its end position, as shown in full lines in Fig. 2, in which position the nut 26 will be positioned to serve as the supporting foot I9 for the machine, should it be desired to place the machine in the operative position of Fig. 1.
