Publication number: 20230050712Abstract: A tilting and telescoping mast assembly having a compact device footprint that can be mounted in close proximity to, for example, a front wall of a truck bed (e.g., adjacent the cab) thereby reducing dead space within the truck bed and maximizing cargo space within the bed. The mast of the present disclosure is configured to be supported by its base in a first position when in the horizontal orientation and supported in a second position when in the vertical orientation, with the first and second positions being spaced apart horizontally and/or vertically.Type: ApplicationFiled: August 11, 2022Publication date: February 16, 2023Applicant: The Will-Burt CompanyInventors: Andrew Paul Wasson, Brian Scott Wetrich, Wendel Mark Niles

Patent number: 10690327Abstract: A folding light tower is provided that utilizes a 4-bar linkage mechanism which enables full vertical extension of the tower with the use of one actuator. The exemplary tower generally includes a base, a lower lift arm, and an upper lift arm. Spring elements are used near the rotating joints of the lower lift arm and upper lift arm of the tower. The spring elements act to preload the joints and help to remove play and movement when the tower is unfolded/during the vertical extension process.Type: GrantFiled: November 15, 2018Date of Patent: June 23, 2020Assignee: The Will-Burt CompanyInventors: Paul Bradford Blackwelder, Andrew Paul Wasson

Patent number: 9574590Abstract: A telescoping mast having a latch assembly includes a latch body mountable to a first tube section, a latch mechanism supported by the latch body, a toggle mechanism operatively connected to the latch mechanism, and a latch plate mountable to a second tube section. The latch mechanism includes a pawl member pivotably between an engaged position for interlocking with a corresponding recess in the latch plate to thereby restrict axial movement between the first and second tube sections, and a disengaged position allowing relative axial movement between the first and second tube sections. The toggle mechanism is movable between an over-center locked configuration corresponding to the engaged position of the latch mechanism and an unlocked configuration corresponding to the disengaged position of the latch member.Type: GrantFiled: November 2, 2012Date of Patent: February 21, 2017Assignee: The Will-Burt CompanyInventors: Neil David Dykes, Paul B.

Publication number: 20150050070Abstract: An automatic locking system is provided that is driven by the normal extension and retraction of the mast, reduces the inherent rotation and deflection of the mast due to clearances, and operates more smoothly and quietly than conventional locking systems. The locking system also fits reasonably within the existing footprint of a typical mechanical mast.Type: ApplicationFiled: November 2, 2012Publication date: February 19, 2015Applicant: THE WILL-BURT COMPANYInventors: Neil David Dykes, Paul B.

Patent number: 8534004Abstract: A rapid deployment and retraction telescoping mast system for controlling the height of a mast. A retraction mechanism including a resilient member, a retraction reel, a reel shaft, and a motor disposed about a frame. The resilient member extends from the retraction reel and is rigidly attached to a top tube of the mast through a sealed passage. The reel shaft rotates the retraction reel and winds the resilient member creating a retraction force on the top tube causing controlled retraction of the mast. A deployment mechanism including a compressor, storage tank, exhaust valve and isolation valve arranged about the frame and in communication with the mast. The compressor generates pressurized air to be communicated to the mast when the isolation valve is in the open position. The increase of pressure generated by the deployment mechanism provides a force within the mast thereby controlling its deployment.Type: GrantFiled: November 5, 2010Date of Patent: September 17, 2013Assignee: The Will-Burt CompanyInventors: Andrew Paul Wasson, Michael James Kardohely

Patent number: 7044566Abstract: A caging arrangement for setting a spring height and correspondingly chamber size in a master cylinder. A cylindrical member has a convoluted surface that is placed in a bore of a piston and a ball is pressed into the cylindrical member to radially expand the convoluted surface into engagement with the piston. A spring is placed on the piston and a disc placed on the spring. A first end of a valve stem having a radial projection is passed through the disc and a force applied to the valve stem while holding the piston stationary such that the radial projection engages and outwardly moves an inward flange on the cylindrical body to allow the radial projection to move past the inward flange. The force is removed and the spring expands until the radial projection engages the inward flange to set distance between the piston and the valve stem.Type: GrantFiled: November 29, 2004Date of Patent: May 16, 2006Assignee: Robert Bosch GmbHInventors: William John Penninger, Andrew Paul Wasson, Thomas David Rothbauer

Patent number: 6402263Abstract: A master cylinder (12) for use in a brake system (10). The master cylinder (12) has a housing (22) with a first (42) and second (44) pistons located in a bore (20) by first (46) and second (48) resilient members to define first (50) and second (52) chambers therein. The first (50) and second (52) chambers are respectively connected to a reservoir (32) to receive fluid and maintain a desired fluid level in the brake system (10) and to front (24,24′) and rear (26,26′) wheel brakes to supply pressurized fluid to effect a brake application. Fluid received from the reservoir (32) by [to] the second chamber (52) is controlled by a center port compensation valve (148). The center port compensation valve (148) has a head (126′) connected to a linkage member (98′) that joins a first retainer (94′) with a second retainer (96′) to cage the second resilient member (48).Type: GrantFiled: July 24, 2001Date of Patent: June 11, 2002Assignee: Robert Bosch CorporationInventor: Andrew Paul Wasson
