A pair of grill panels are provided and include first and second corresponding remote marginal portions and pivot structure is provided pivotally connecting the first marginal portions together for relative angular displacement of the grill panels. In addition, a first marginal portion of one of the grill panels includes follower structure slidably engaged with the opposite side guide assemblies of the base for sliding and pivotal movement relative thereto and the opposite side guide assemblies include elongated guide members extending generally normal thereto with which corresponding side portions of the second grill panel are slidably engaged.

Abstract: A fryer for cooking foods by immersing the food in heated oil. The oil is circulated through a cooking tank and through a separate heat exchanger. The rate of oil flow is fast enough to maintain turbulent flow in the heat exchanger for maximum heat transfer to the oil from the heat exchanger surfaces. High velocity oil flow in the tank provides maximum heat transfer from the oil to the food being cooked. The fryer may also include a cylindrical drum for carrying food through the cooking tank. The cooking tank will be semi-cylindrical, and food is carried by perforate shelves carried by the drum. The shelves are angled so food slides off a shelf when the shelf moves out of the tank; and, after some further rotation of the drum the shelf can receive food. The food is carried around the drum, preheated by being held over the heated oil, then moved through the oil. The drum can be loaded and unloaded from the front.

Abstract: A counterbalance device for a rotary shaft comprises a sleeve member in the form of a short tubing or a handle which can be mounted on the rotary shaft. The sleeve member has an extension rear portion adapted to receive a bushing member to be mounted thereon. The bushing member is provided with at least two aligned openings. A rod can be inserted through these openings and be mounted on the bushing member by a set screw. At least one counterbalance weight can then be mounted on the rod to provide counterbalance for uneven weight distribution with respect to the longitudinal axis of the rotary shaft.

Abstract: A windshield wiper system having a wiper blade movable across the windshield through a wiping arc and through a parking arc to a depressed park position below the lower edge of the windshield, a pair of guide links on the body movable between extended and retracted positions in a plane forming an acute angle with the windshield, and a pair of cams on the wiper blade engageable on the guide links as the blade moves toward the depressed park position to lift the wiper blade off of the windshield, the torque of the wiper drive motor thereafter holding the wiper blade against the guide links as the latter move to their retracted positions so that the wiper blade is guided in the plane of the guide links to the depressed park position.

Abstract: An automatic can crushing machine, preferably used for compressing standard aluminum 12 ounce beverage cans, is constructed of a housing having an angularly inclined feed chute for receiving a supply stack of cans to be crushed therein and an adjacent, parallel-arranged crushing station in which a piston reciprocates back and forth to crush the cans one at a time delivered from the feed chute. The feed chute is adapted to contain a serial stack of spent cans which are disposed, under the influence of gravity, to pass downward in the chute toward an ejection end. An ejector mechanism in the form of a plunger passes transversely through the ejection end of the chute to force a can about to be crushed through a delivery opening covered by a flap valve for deposit into a trough mounted in the crushing station. A crushing piston reciprocates within the trough. Movement of the crushing piston along the trough longitudinally compresses the can to approximately one-eighth of its original length over an outlet gap.

Abstract: Hollow wind turbine blades and the like comprising abutting blade sections, with nose forming strips and converging walls forming a tail section connecting with the ends of the nose forming strips, and a method of fabricating them comprising machining the facial end walls of the abutting blade sections to provide a precise alignment thereof providing a flush joint when the sections are butted together, adhesively bonding the blade sections in abutting relation and permitting the bond to cure, cutting communicating splice receiving slots in the abutting nose forming strips, and inserting adhesively bonding splice inserts which fit the slots in place in the slots.

Abstract: A radial blower, especially for heaters and/or air conditioning systems of motor vehicles. The radial blower including a housing having a front portion provided with an air intake opening and a back portion provided with discharge or exit openings. The housing is adapted to accommodate a drive motor for a fanwheel which is manufactured as a one piece plastic part. The fanwheel includes a fan ring with fan blades and a hub. A spacer is provided for connecting the fan ring with the fan blades. A spacer is provided with openings having spokes disposed therebetween. The spokes constitute a bundle of springs connected in parallel. Openings in a back portion of the housing and/or the drive motor have a limited cross section for drawing in a sufficient flow of cooling air.

Abstract: A barbecue grill comprising a fire bowl, legs for supporting the fire bowl, a cooking grill above the fire bowl rotatable about a generally vertical axis, and a rod which is selectively mountable in a generally horizontal position above the cooking grill for use as a spit and in a generally vertical position for use in rotating the cooking grill. A single motor is used to turn the rod, the motor being selectively mountable in two different locations on the barbecue grill depending on whether the rod is being used as a spit or to rotate the cooking grill.

Abstract: The disclosure relates to a composite turbine wheel comprising a hub having a plurality of radially extending blades thereon. The hub and blades comprise a plurality of discrete axially spaced layers of radially extending carbon fibers and circumferentially extending carbon fibers. Hoop strength is given to the hub of the turbine wheel by the circumferentially oriented fibers and radial strength is given to the blades by the radially oriented fibers. Transmission of shear loads between the radial and circumferential fibers is minimized.

Abstract: Apparatus and method for minimizing and maintaining substantially constant the effective blade tip clearance between the outer free ends of rotor blades and an adjacent casing shroud of an axial-flow turbine of a gas turbine engine. The casing shroud includes a portion facing the hot gas stream and the outer rotor blade ends and a packing of high heat-resistance, high erosion-resistance ceramic elements secured to the shroud via a metal ring to face the blade tips. A heat insulator is interposed between the packing and the metal ring. A perforated conduit is mounted outside the metal ring for blowing cooling fluid against the metal ring on the side thereof remote from the insulator for equalizing the expansion of the metal ring to that of the turbine wheel. The ceramic packing includes projections facing the outer ends of the blades which are tapered so that they are easily broken off when coming into contact with the blades during running-in of the apparatus.

Abstract: A rack for use with a grill having a cooking surface defined by spaced rods is formed by bending two wires that define a base and an upright article-receiving support extending above the base. The base has spaced, generally L-shaped projections that are inserted between two spaced rods and under one rod to secure the rod on the cooking surface.

Abstract: This invention relates to an annular rotating roaster. The user may apply a cone-shaped flame separator which has numerous outstanding scales on its inner wall, when making a fire in the roaster. Each of the scales has a perforation beneath. The heat from the burning charcoal goes through the perforations and the scales to the meat. Thus, the meat won't be scorched. In addition, the degree of heat exposure is adjusted by the turning handle. Therefore, tender meat is produced. Moreover, the fat from the hot meat does not drop directly on the burning charcoal. As a result, no smoke or ashes rise, keeping the meat from being contaminated.
