M invention consists of an apparatus for feeding ones self by means of a spoon or fork or other similar device adapted to re-v move portions of food from a holding 'dish' or plate, by means of' actuating hmechanism operated by the foot or feet of the user. It

has in view to provide such a devicecapable ofuse by a person having lost his arms, or thelr use, and to enable him to transfer food fromV a vessel, which is itself preferably adjustable, to a positionwhere'it may be easily taken'into theV mouth.. Y Preferredembodiments of the invention are shown vin-the Vaccompanying drawings, in which:

lAt one side of the normal position of the dish an upright plate 14- extends upwardly from thebase 2to which it is rigidly secured, and this-.plate is lcut out at its middle portion to provide the necessarytriangular clearance yfora swingin cam plate l5, pivoted at 16 to a `bracket Thecam plate 15k is provided with a pivoted counterweight'lS adaptedl to be thrown over upon
