  • Publication number: 20110146601
    Abstract: Disclosed are crankshaft, single-plate cam and beam mechanisms that provide significant improvements in performance for 2- & 4-stroke engines, compressors and pumps. These cost effective mechanisms include linkages with the new and improved use of pivoting arms that operate with a variety of cylinder arrangements. One embodiment of the crankshaft mechanism has its crankpin roller positioned within a novel yoke-arm. The cam mechanism uses a pair of centrally positioned parallel links that are connected to roller cam followers and single or diametrically-opposed pistons. A pair of laterally extending follower arms connects to the ends of the links to provide support and alignment for the piston rods. Between the reciprocating links, cam followers and follower arms is a rotating odd-lobe plate cam. A beam mechanism uses opposite-direction extending balancing beams that are connected to links, cam followers and piston rods.

  • Patent number: 5197380
    Abstract: This egg breaking machine provides a means for separating egg shell from the liquid part of the egg. The eggs (1), along with the egg holder, commonly called a filler flat, containing thirty or less eggs, are placed into the egg breaker pan (3). At one end of the pan is attached a hinge (5) that is also attached to the upper section or egg support guide (6). The egg support guide has holes (7) that allow the egg tops (8) to fit through. With the eggs and egg holder placed inside the egg breaker pan, the guide is placed down on top of the eggs exposing the top section of the eggs. Placed on top of the support guide, there is an egg cutter (12) made from a flat metal plate attached to a horizontal support beam that rotates from a connecting rod placed at the end of the pan opposite the support guide hinges.

  • Patent number: 4381739
    Abstract: In an internal combustion engine, a combination of cylinders, pistons, rods, beams, gears and cams that are used for converting the reciprocating motion of the pistons into rotary motion of the drive shaft. One embodiment includes a block member that is fastened to four opposed in-line cylinders, that contain pistons that are attached to the ends of connecting rods and the opposite ends of the rods being attached to roller bearings and to the ends of two rocker beams. The beams, that oscillate in the same plane side by side, each have a separate shaft passing through their centers which are supported by the block member. Located at each of the two ends of the two rocker beams, there is a cam with shaft, that is placed between two of the roller bearings, and these two cams are connected by gears that cause the two cams to rotate in the proper position in relation to each other for the proper engagement of the cams bearing surfaces with the roller bearings.
