A cover is manually releasably locked to the base of a storage container for protecting the contents of the container from accidentally or inadvertently opening even on dropping. A forked member is mounted on the cover having tongues with eyelets extending downwardly therefrom which fit into a latch housing in the base which contains slots for receiving the eyelet tongues. A slidable actuator is movably mounted in the latch housing which housing includes a first and second latch which are adapted to engage the eyelets of the tongues of the stem when the cover is closed on the container. Spring means are provided for urging the first and second latches into the eyelets which are released by a multiple-step technique in which the actuator is moved in a first direction for removing the first latch from one of the eyelets and then moved in a second opposite direction which removes the second latch from the other eyelet, and by gently, continuously and evenly lifting the cover upwardly while the latches are being released in sequence. If the actuator is moved too far in the second direction, a third latch engages for preventing opening. If the continuous lifting force on the cover is too strong the lock cannot be opened. If the gentle continuous lifting force is uneven or interrupted one of the latches becomes engaged by the spring means for preventing opening, thereby preventing the accidental or inexperienced, unauthorized opening of the container.

A method and apparatus adapt a beater/whipper unit to be used in food processor bowls of varying diameter which have upstanding side walls wherein a revolving head of the beater/whipper unit is mountable on an upstanding central well of each working bowl. The revolving head carries a pair of closely spaced counter-rotating beaters which extend downwardly from the revolving head toward the bottom of the bowl so that the beaters are revolved around the central well by the revolving head. A deflector blade having an inclined front surface is detachably mounted on the revolving head when the beater unit is intended to be used on a working bowl having an upstanding side wall of a first predetermined large diameter. The deflector blade is inclined radially inwardly with respect to the direction of travel of the revolving head for deflecting ingredients in the bowl inward from the side wall toward the counter-rotating beaters. When the beater/whipper unit is intended to be used on a working bowl of smaller diameter, the deflector blade of the beater/whipper unit is removed and replaced with shorter counter-rotating beaters having larger diameters which thereby extend near to and are thereby revolved near the smaller diameter upstanding side wall of the smaller diameter bowl without any intervening deflector blade, thereby adapting the same beater/whipper unit to be used in food processors having different diameter bowls.

A bowl extender-actuator-and-adapter support has larger upper and smaller lower annular channel members separated by an intermediate shelf and is adapted to be mounted on the bowl of a food processor wth the lower channel member extending down into the bowl and is terminated at its lower end in a spider support web having a central opening in alignment with the rotary drive of the food processor extending up into the bowl. A plurality of radially spaced support ribs below the intermediate shelf define a plurality of mounting steps for enabling this adapter support to be mounted upon food processor bowls of various sizes. An actuator on the shelf extends downwardly outside of the bowl for activating the interlock switch of the food processor. A speed-reduction torque-increasing transmission gear drive unit positioned in the central opening of the spider is coupled to the rotary drive of the food processor and has an upwardly extending shaft for driving attachments positioned thereon at reduced speed with increased torque. A juicer attachment includes a rotating basket integral with a centrally located juicer reamer which is adapted to receive larger sized reamers in telescoped relationship locked for rotation on a splined base. A pureer/strainer attachment is mountable on the shaft of the transmission unit and includes a bridge support for positioning a pair of rearwardly inclined wiper blades extending down into the strainer for pushing food items through the strainer.

Method and apparatus for quickly and effectively grinding kernels of grain, such as wheat or corn, coffee beans, and the like, in a food processor producing a finely divided or flour-like consistency food product or condiment. Nutritious home-ground whole-grain flour can be conveniently and quickly made. The kernels, grains, beans, or other food products to be ground are introduced into a hopper positioned above the bowl of the food processor and located above a grinder assembly including a downwardly converging then diverging stator grinding member which encircles a rapidly rotating rotor grinding member having a vertical axis of rotation and being positioned within the stator member. This rotor grinding member is coupled to the vertical tool shaft of the food processor which extends up into the bowl. The separation between stator and rotor grinding members is manually adjustable and settable by a hand knob located above the grinder assembly for controlling the consistency and fineness of the ground product, which is deposited from the grinder assembly into the bowl. The illustrated grinder attachment for a food processor may be conveniently operated, adjusted, controlled and cleaned in a safe, efficient manner utilizing without alteration the basic components of the food processor, namely the motor drive, safety interlock system, as well as the bowl.

An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photoconductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photoconductive member.

Dual actuating apparatus is provided for a food processor of the type having a motor with a working bowl, a motor-driven member in the bowl for receiving rotatable tools and with a removable cover positioned on the bowl during the operation which carries a feed tube for feeding food items to be processed into the bowl. An expanded feed tube protector has an outer sleeve which is adapted to be nested over the feed tube and this sleeve is associated with a captivated, movable food pusher which is mounted for movement within the sleeve. In accordance with the present invention the cover and the outer sleeve of the feed tube protector each carry a portion of a dual actuator cam, a first portion of the cam being mounted on the cover while the second portion is mounted on the outer sleeve of the feed tube protector. Previously the cam for depressing the actuator rod of the food processor was a one-piece unit mounted and extending downward from the outer sleeve of the feed tube protector. The advantageous separation of the cam into two portions acting in dual relationship assures that the food processor is not operative unless the two portions of the cam are positioned together in cooperative action side-by-side on the bowl requiring the placement of both the cover and the feed tube protector in their proper positions on the working bowl before the food processor can be actuated.

A horizontal disc-like tool head is detachably mounted on an upper coupling portion of an elongated hub, while a lower coupling portion of the hub is adapted to be coupled to and rotated by the tool drive shaft of a food processor. The tool head has a receptacle underneath it for receiving the upper coupling portion of the hub, which has a flange-like configuration with spaced, projecting, peripheral teeth. The receptacle has a plurality of spaced, lip retainers which are adapted to receive and retain such teeth when the hub is inserted in an axial direction and then rotated about the tool axis for changing its angular orientation in the receptacle. The teeth and lip retainers have corresponding matching sizes, so that the hub properly fits into the receptacle in only one position, thus preventing incorrect insertion of the hub. A spring-loaded receptacle rod protrudes from the upper coupling member, and this retractable rod and its associated locking recess are offset from the axis of tool rotation for preventing removal of the hub from the receptacle, unless the rod is manually retracted by its release button. During manufacture, the receptacles in various tool heads may be provided with different size shims mounted between the receptacle and the lower surface of the tool head for producing slicing tool heads having different slicing thicknesses without changing hub length. Accordingly, one elongated hub can be used with several different tool heads.
