Abstract: Systems and methods are provided for delivering a work part to an assembly line worker using a dolly assembly in a first configuration and retrieving the work part from the dolly assembly by the assembly line work while the dolly assembly is in a second configuration. According to some embodiments, a dolly assembly is provided comprising a base assembly having a support member and a mobility mechanism, the support member positioned obliquely with respect to a horizontal plane. The dolly assembly also includes a part-carrying member rotationally connected to the support member and having a part-holding structure for receiving a work part. The part-carrying member extends downward at an angle below the horizontal plane when in a first configuration, and extends upward from at an angle above the horizontal plane when in a second configuration.

Abstract: The present invention relates to shaker doors with solid cores and methods for making the same. The shaker doors contain different core materials at the recessed panel than the raise peripheral region to provide dimensional stability and reduced distortion when the doors are exposed to high humidity. The devices and methods also provide for easy assembly of solid core shaker doors, including fire rated doors.

Abstract: A proximity sensor bar can be configured to sense or detect the presence or absence of objects on a conveyor system. The proximity bar can implement multiple sensor blocks for such sensing with each sensor block including one or more electronic proximity sensors and with each sensor block being spaced a predetermined distance or interval apart from one another along the bar. The proximity bar can be used on conveyor systems, such as roller conveyors in an object movement and distribution environment, with the proximity bar spanning the width of the conveyor. In such systems, the proximity bar could be mounted between adjacent rollers or below such rollers. The proximity bar can also be used on other conveyor systems, such as belted conveyors, by mounting the proximity bar above the conveyor.

Abstract: A self-centering device for assuring that two plates that are rotatable with respect to one another will automatically align in one of two-stable positions. The device includes an O-ring entrained about two spaced posts located on the upper face of a bottom one of the plates and a roller depending from the bottom face of the upper one of the plates into a circumscribed space defined by the O-ring. When an external rotatable force is applied to the upper plate, an elastic force is applied to the roller such that when the external force is removed, the roller will move into one of the two stable positions.

Abstract: Accessories for a pickup truck includes a front brush/grill guard, a tubular rear bumper and a rally bar with lights. The brush guard has upper and lower flanges and offset front and rear mounting brackets which sandwich the flanges therebetween to fasten the guard on the front bumper of the truck. The rear bumper assembly has first and second tubes with angled end portions which angle inward toward the truck body. The ends of the tubes are parallel to the truck body for aesthetic appeal. The tubes provide a license plate mounting area and are mounted using large and small bumper tabs, a frame bracket and a tube bracket. The rally bar assembly includes front and rear rally bars releasably connected by a two member bracket. The bracket has a front member fastened to the front bar and a rear member connected to the rear bar. The bracket also supports a light assembly for projecting light forward of the vehicle.

Abstract: A locking valve for selectively locking fluid pressure in a fluid cylinder in the event of failure of the source of fluid pressure to the cylinder and including an integral fluid flow control valve, the locking valve also including a fluid pressure seal between the fluid supply port and the pilot port of the locking valve to prevent back pressure on the pilot pressure operated valve components.

Abstract: An apparatus for stacking a plurality of articles in a side-to-side relation. The articles are conveyed in an upright end-to-end relation on a conveyor and a bin or article receiving member is positioned adjacent the downstream end of the conveyor and individually receives each article discharged from the conveyor. The bin includes a bottom wall and a rear wall and the bin is movable between a receiving position where the bottom wall extends downwardly and outwardly from the downstream end of the conveyor, to a discharge position where the bottom wall is disposed substantially horizontal. Each article being received within the bin is held in an upright position and is transferred laterally within the bin against a movable support plate, and each succeeding article received in the bin is transferred in a similar manner against the preceding article to form a stack.

Abstract: An apparatus for joining and folding container sections to form a hinged container. Two container sections are transported in end-to-end relation on a conveyor and the downstream section is engaged with a stop while a pusher member is pivoted into engagement with the trailing edge of the upstream section to force the sections together and engage snap fitted hinge elements on the two sections. The hinged container is then discharged from the first conveyor onto a second conveyor located at a level beneath the first conveyor and operating at a slower speed than the first conveyor. As the leading section of the hinged container falls from the upper conveyor onto the lower conveyor the increased speed of the upper conveyor will fold the trailing section over the leading section to provide a closed hinged container. The closed container then passes under a spring loaded pressure member which ensures that locking elements on the two container sections are fully engaged.
