Patent number: 10571038Abstract: A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.Type: GrantFiled: July 17, 2018Date of Patent: February 25, 2020Assignees: OPW Engineered Systems, Inc., Operations Technology Development, NFPInventors: Joseph P Roth, Michael Crum, Dennis R.

Patent number: 10299597Abstract: A mechanism is provided for a seating unit that moves the seating unit between closed, TV, and fully reclined positions. The mechanism allows positively holds a footrest in a closed position, preventing the footrest from sagging over time. The mechanism includes a linkage that forces a link connected to the footrest to move initially upwards as the footrest moves from a closed position to an extended position. The weight of the mechanism holds the footrest positively closed, until a force is exerted that is great enough to move past the point where the link on connected to the footrest can descend.Type: GrantFiled: February 13, 2018Date of Patent: May 28, 2019Assignee: L&P PROPERTY MANAGEMENT COMPANYInventor: Michael Crum

Patent number: 9581276Abstract: A fluid system includes a loading arm connected to a swivel joint. A counterbalance mechanism is connected between the loading arm and the swivel joint. An adjustment mechanism adjusts the counterbalance force applied by the counterbalance mechanism to the loading arm. The adjustment mechanism includes a guide plate connected to the swivel joint and includes a guide slot and a straight bore guide. A bracket is movably connected to the guide plate and has one or more apertures and a threaded bore guide. Fasteners extend through the guide slot and the one or more apertures to selectively secure the bracket to the guide plate. A lead screw is disposed at least partially within the straight bore guide and the threaded bore guide. Rotation of the lead screw causes the bracket to move along a length of the lead screw and thereby adjust the counterbalance force.Type: GrantFiled: June 19, 2013Date of Patent: February 28, 2017Assignee: OPW-ENGINEERED SYSTEMS, INC.Inventors: Michael Crum, Krzysztof Wejdman

Patent number: 9433295Abstract: A zerowall motorized multi-position recliner chair mechanism is disclosed wherein, in accordance with a first embodiment, the chair seat rails are stably supported by means of a pair of oppositely disposed support linkage systems connected to the chair base rails. In addition, the rear sections of the pair of oppositely disposed support linkage systems are pivotally connected to the base rails at first pivot points, while the drive motor is pivotally mounted upon an integral structural unit so as to permit the drive motor to pivot around a second pivot point which is coaxially disposed with respect to the first pivot point. In this manner, the drive motor is substantially fixed, or at least positionally constrained, at a predetermined position with respect to the base rails, thereby providing additional stability to the chair. In accordance with a second embodiment, the drive motor is attached directly to the rear base rail.Type: GrantFiled: October 15, 2014Date of Patent: September 6, 2016Inventor: Michael A. Crum

Patent number: 9022473Abstract: A rocker-type seating unit that includes a base for providing vertical support, a seat support, and a backrest support. The seating unit adjusts between an upright position and a reclined position. The seating unit includes a support frame, a seat assembly, and a rocker mechanism. The support frame includes lower crossbeams coupled to the base, and a traverse plate fixedly attached to and extends upward from the lower crossbeams. The seat assembly includes a seat frame for carrying the seat support over the support frame, seat-mounting plates fixedly attached to and extend downward from the seat frame, and an upper crossbeam that spans and couples the seat-mounting plates. The rocker mechanism is connected to the upper crossbeam on one end and connected to the traverse plate on another end. The interconnection of rocker mechanism enables a controlled, fore-and-aft sway of the seat assembly with respect to the support frame.Type: GrantFiled: May 2, 2013Date of Patent: May 5, 2015Assignee: L&P Property Management CompanyInventor: Michael A.
