Patent number: 9555730Abstract: A self-unloading bulk material bed with a discharge opening is provided. An apparatus for discharging materials from the self-unloading bulk material bed includes a first and second tapered fin on either surface of the discharge opening. The tapered fins direct materials moving through the discharge opening down so that they do not build up around the discharge opening.Type: GrantFiled: June 3, 2016Date of Patent: January 31, 2017Assignee: Trinity Trailer Mfg, Inc.Inventors: Matthew Lynn Hobbs, Wayde Johnson

Publication number: 20120267912Abstract: A tarp bar may be an alignment, reinforcement, and furling control member, without adding substantial weight or complexity to a rolling tarp system. The tarp bar is not motorized or otherwise powered, and is preferably attached only to the tarp material, a significant distance from the drive bar and parallel to the length of the tarp and the bed/trailer. The tarp bar is recessed or otherwise-concave along its length to allow cradling of, and hence parallel orientation of, an already-rolled portion of the tarp. The tarp bar is preferably broader than said already-rolled portion and the combination of the already-rolled portion received in the tarp bar is a non-cylindrical unit. Subsequent rolling-up of the tarp tends to occur in a cam-like action that maintains more consistent tension all along the length of the tarp, to form a tighter and more even roll.Type: ApplicationFiled: April 24, 2012Publication date: October 25, 2012Applicant: TRINITY TRAILER MFG., INC.Inventors: JAMES C.

Patent number: 8162377Abstract: A tarp bar may be an alignment member, a reinforcement member, and a furling control member, without adding substantial weight or complexity to a rolling tarp system. The tarp bar is fixed to the tarp a significant distance from the drive bar and is not motorized or otherwise powered, and is preferably attached only to the tarp material, parallel to the length of the tarp and the bed/trailer. The tarp bar is recessed or otherwise-concave along its length to allow cradling of, and hence parallel orientation of, an already-rolled portion of the tarp. The tarp bar is preferably broader than said already-rolled portion, so that two opposing edges of the tarp bar extend out beyond the diameter of the already-rolled portion so that the combination of the already-rolled portion received in the tarp bar is a non-cylindrical unit.Type: GrantFiled: August 6, 2009Date of Patent: April 24, 2012Assignee: Trinity Trailer Mfg., Inc.Inventors: James C.

Patent number: 7597191Abstract: A self-unloading bed includes a conveyor with chain bars that are strong, light-weight and non-damaging to the floor upon which the conveyor slides. The preferred chain bar is an elongated bar with two legs, each of said two legs having a foot. The feet extend away from the leading (unloading) direction, the transition from leg to foot being formed by smooth bends, so that no sharp edges exist that would gouge into the floor as the chain bar moves across the floor. The preferred chain bar, made of a single metal bar with four longitudinal bends, is extremely strong for its weight, and it unlikely to bend or gouge into the floor during use.Type: GrantFiled: May 2, 2006Date of Patent: October 6, 2009Assignee: Trinity Trailer Mfg., Inc.Inventors: Peter L. Eisenman, James C. Miller, Ren Barry Bai
