Abstract: A hinge for a range door and the like having a frame bracket (18) adapted to be mounted to a range housing, a hinge arm (40) adapted to be mounted to a range door and pivotably mounted to the frame bracket (18) and a cam follower arm (16) pivotably mounted to the frame bracket (18). A cam follower element (76) on the cam arm (60) is biased by a tension spring (80) against a cam surface on a cam arm portion (46) of the hinge arm to counterbalance the weight of the range door. The cam surface has indentations (50, 52) which define equilibrium positions of the door for an ajar and fully open position. A tab stop (34) is struck out from the frame bracket (18) to stop the pivotable movement of the cam follower arm (60) as the hinge arm (40) reaches the fully open position (FIG. 5). The cam follower arm (60) has a number of indentations (64) for receiving one end (84) of the spring (80) to adjust the counter-balancing force on the oven door.

Abstract: The specification discloses a light-duty conveyor roll bearing which is quiet, static conductive, and capable of operating at relatively high speeds. The bearing includes a stamped, cup-shaped outer race; an inner race positioned therein; and an end cap crimped to the rim of the outer race to shield one side of the ball raceway, to provide a thrust bearing surface for the balls, and to provide a seal contacting surface. Opposite the end cap, the outer race extends radially inwardly adjacent to or beyond the inner race to shield the other side of the ball raceway. A graphite-filled, electrically conductive, polymeric hub supports the inner race and includes an annular seal contacting the end cap to seal the one side of the ball raceway.
