Patent number: 3951054Abstract: A spiral meat slicer especially for cutting ham, wherein the ham is mounted vertically on a spiked platform which slowly revolves. A rotating disk blade is brought into engagement with the periphery of the ham to cut the ham to the bone. The blade support is mounted on a lead screw so that the blade steadily rises as the ham rotates. Thus an unbroken spiral cut of ham is produced. In order to permit selective manual control when cutting around the aitch bone, a manually manipulatable arm is provided, by which the blade may be selectively moved toward and away from the rotative axis of the ham. Once the aitch bone has been cleared, the arm is detented into an extreme position and thereafter the blade is automatically biased toward the ham with a predetermined spring force, by means of a biasing spring.Type: GrantFiled: September 24, 1974Date of Patent: April 20, 1976Assignee: Collins Foods International, Inc.Inventor: Herman E.

Patent number: 3935808Abstract: A method and apparatus for milling grain while simultaneously cooking the grain in which the grain is introduced between coaxial relatively rotatable grinding members and advances therebetween while being milled. The milling of the grain develops heat in the grain which converts the moisture therein to steam which effects cooking of the grain. Most, if not all, of the steam thus generated is reabsorbed by the milled grain as it emerges from the apparatus. In order to enhance the cooking effect on the grain, the outer one of the conical grinding members has a heated gaseous medium supplied thereto and the mill includes an impeller for forcing the gaseous medium through the inner one of the grinding members so that both of the grinding members are heated and thereby enhance the cooking of the grain being milled in the apparatus.Type: GrantFiled: September 5, 1974Date of Patent: February 3, 1976Inventor: Fausto Celorio Mendoza
