Abstract: A sliding door roller fitting includes a tilting lever having a long and short arm angled thereto. The long arm has a freely rotatably mounted running roller which projects beyond the long arm to roll along a running rail. The short arm has an outwardly curved outer side facing away from the running roller. The tilting lever is held on a sliding door-side bearing body and is tiltable between two end positions about a tilting axis parallel to a running roller tangent. The bearing body has at least one planar bearing surface which extends horizontally in the setting-out direction in the mounting position of the bearing body. The short arm of the tilting lever bears by its curved outer side against the bearing surface and rolls thereon during tilting of the tilting lever. The bearing body has two driving stops between which the tilting lever is arranged.

Abstract: An arrangement for guiding a door on a furniture wall, includes a guide to be secured on the furniture wall, a carrier on which the door is to be secured, and a guide body.

Abstract: Methods and systems for improving vacuum generation for an engine that may be operated at higher altitudes are presented. In one non-limiting example, a transmission that is mechanically coupled to the engine may be shifted from a gear to neutral in response to an actual total number of times a vehicle brake pedal is applied and partially released while the vehicle is stopped and the brake pedal is applied.

Abstract: A window roller apparatus comprising a cradle, a housing pivotably installed in the cradle, and at least one roller wheel rotatably installed in the housing. Cradle side walls are formed with opposite inwardly-opening cradle side wall recesses, and respective housing side walls are formed with opposite inwardly-opening housing side wall recesses and with opposite outwardly-projecting bosses configured to pivotably engage the respective inwardly-opening cradle side wall recesses. The at least one roller wheel has an axle that engages the housing side wall recesses. A resilient pad is positioned on the cradle bottom wall between the cradle and the housing, the pad being of a sufficient size and thickness to at least partially engage the housing and effectively bias the housing toward a parallel orientation relative to the cradle while allowing for non-parallel operation of the housing relative to the cradle as dictated by operational constraints on the window roller apparatus.

Abstract: A mechanism for moving a sliding door of a railway car is capable of moving the sliding door between a first position in which the sliding door is supported on the body of the railway car and closes an opening in the railway car body and a second position in which the sliding door is supported by the mechanism and is moveable along the railway car body so that cargo may be loaded and unloaded into and out of the opening in the railway car. The mechanism includes a crank and a roller rotatably mounted on the crank. The crank is rotatably mounted to the sliding door about an axis of rotation which allows movement of the roller through an opening in the bottom portion of the sliding door while limiting lateral movement of the crank which allows for clearance between the roller and the opening when the roller moves through the opening in the sliding door. An actuating member is provided and is rotatably mounted on the sliding door about an axis. The actuating member has at least one lug thereon.

Abstract: A supporting roller assembly for a sliding door has a downwardly spring loaded guide track engaging roller supported for vertical floating movement by a mounting bracket containing a limited stop plunger which is spring loaded downwardly against the roller carrier. The bracket is slotted and carries a clamp screw accessible from the side of the door for clamping the bracket firmly about the plunger to secure the plunger in a fixed position for limiting upward movement of the guide roller against the action of its spring.

The lifting mechanism includes a cam element which is manually rotated to exert a push force on the bell crank levers for pivoting the same into the lift position. A modified version of the lift mechanism includes a linkage arrangement which exerts a pulling action on the bell cranks for achieving the lifting function.

Abstract: A runner wheel support for sliding doors, windows and the like consists of a support body which is a press fit in the respective frame, and which carries the support wheel or roller on an arm carried by a disengageable pivot. The wheel support arm has a cam member cooperating with a height adjustment screw and spring fingers on the support body to hold the wheel support in a stored position while the support body is fitted into a frame member, and thereafter to free the wheel support from this stored position and to hold it in an operative position. Preferably the support body is of L-shape and acts as a connector to join together mitre-cornered pieces of frame. Movement of the wheel support arm to a removal position disengages the cam member from the spring fingers, so that the arm can be disengaged from the pivot and removed.

Abstract: A roller wheel assembly for a sliding closure has a wheel unit which is supported in a frame for vertical motion relative thereto when the assembly is installed in the closure. Means in the form of a wedge assembly which engages sloped surface means in the wheel unit are provided to vertically adjust the wheel unit relative to the track. The wedge assembly is adjusted sidewise by means of a screw assembly which is operated from the side of the frame. This causes wedge shaped surfaces of the wedge assembly to ride along the sloped surface means to afford a continuous and precise vertical adjustment of the wheels.
