Abstract: A hand-operated food mixing/folding device for doughs, sauces, mousse or the like incorporates a rounded or contoured bottom bowl provided with a mount which removably supports the bowl on a conventional kitchen counter or table, the axis of the bowl extending at an angle of approximately 45.degree. to vertical. A mixer arm is mounted for rotation around the axis of the bowl, and has a driving connection to a hand crank supported by the mount. Preferably the mount includes a vertically extending post fitted with a clamp mechanism at its lower end which can grip the edge of a table or countertop and support the bowl in the aforementioned orientation. The mixer arm has a contoured lifting/folding surface with a leading edge (preferably flexible) closely following the sidewall contour of the bowl, and a knife edge on an opposite part of said arm from the folding surface.

Abstract: A spray system is disclosed for forming directed streams of liquid under pressure. A supply conduit having an open end and a manifold communicating with a plurality of spray nozzles and having an inlet conduit with an open end cooperate for insertion of the inlet conduit into the supply conduit to connect the manifold to the supply conduit, the manifold is placed near the supply conduit in a predetermined but misaligned position. A plate having a slot defines at least a portion of a pair of cam surfaces and a wash arm formed on the manifold defines a cam follower. Rotation of the inlet conduit about its central axis causes the cam follower to contact and cooperate with the cam surfaces to produce lateral force along the inlet conduit, thereby forcing the same into fluid-tight engagement with the supply conduit.

Abstract: The section modulus of elasticity of the body portions of the scraper blades in a meat scraping machine decrease substantially uniformly outwardly along each blade. The blades have flat, transversely flexible scraping edges on the ends opposite a common series of circular hubs. Each hub is slightly rotated with respect to the adjacent hub to provide a series of spiraling blade-like edges for engaging and scraping accumulated residues from the sawed surface of a piece of meat. An adjustable doctor blade removes the residue from the scraper blades. The uniformly decreasing section modulus of elasticity of each blade encourages uniform flexing along the length of each blade to distribute stresses and fatigue uniformly throughout the blade material. The blades are pre-flexed on the hubs to reduce the effective diameter of the blade structure and to reduce the flexing of the blades when encountering the meat and the doctor blade.

Abstract: Each of the meat gripping and moving cylinders in a meat scraping machine may be removed from the machine as a complete subassembly and disassembled quickly and easily for cleaning, without the need for tools. Each cylinder includes a carrier framework mounting removable ring supports which maintain a plurality of separate, toothed, blade-like meat gripping and driving rings in spaced, concentric position on the framework. During assembly, the rings are placed on the framework before the last support is inserted. The last support is then inserted and locked in position, which locks the rings into position on the framework.

Abstract: The pivoted mount connecting two opposing sections of a meat scraping machine suspends the movable section for swinging gravity-induced movement toward the stationary section. The stationary section is the sole support for the movable section and wholly encloses the power source for the machine. A drive connection passes into the movable section through the pivoted mount, so the drive system for the entire machine is wholly contained within the two opposing sections, entirely free from exposure to the outside environment. The result is a sanitary drive system for the machine.
