Patent number: 8656648Abstract: A modular wall panel system including a series of wall panels connectable to each other. Each of the wall panels is formed from a support frame having a pair of spaced vertical posts and an upper header and a lower sill extending between the vertical posts. The lower sill is received within attachment notches formed in each of the vertical posts near the bottom end of each post. The attachment notches are spaced along the length of the vertical post such that the position of the sill can be adjusted. The lower sill includes a trim channel that receives the bottom of a tile mounted to the support frame. A top cap is attached to the header and engages a top end of the tile to aid in retaining the tile on the support frame. The tile may be a segmented tile having a lower portion and an upper portion joined to each other by a segmented trim channel. The segmented trim channel between the upper and lower portions is not connected to the support frame.Type: GrantFiled: October 27, 2010Date of Patent: February 25, 2014Assignee: Krueger International, Inc.Inventors: David D. Liegeois, Daniel R. Cummings, Steven C. Gevaert

Patent number: 8215081Abstract: A system and method to attach and retain panel tiles and a top cap to a support frame of a modular wall panel system. The top cap attached to the support frame includes an elongated body having a one or more attachment clips removably attached to the elongated body at desired locations along the length of the elongated body. The attachment clips and elongated body are formed separately and assembled prior to attachment to the modular panel. The elongated body includes a pair of receiving cavities that receive spring arms formed on each of the attachment clips. The attachment clips are rotated into position such that the spring arms engage the elongated body and hold the attachment clips in position. Each panel includes a stiffener bracket having engagement tabs. The engagement tabs are received within notches formed in the vertical posts to secure the tiles to the support frame.Type: GrantFiled: January 25, 2010Date of Patent: July 10, 2012Assignee: Krueger International, Inc.Inventors: Daniel R. Cummings, David D. Liegeois, Steven C. Gevaert

Patent number: 6622481Abstract: An exhaust treatment device is provided for an internal combustion engine of a marine propulsion system. An outer chamber contains a first inner chamber within it and slidably supports the inner chamber. An exhaust inlet conduit directs a stream of exhaust gases from a cylinder of the internal combustion engine directly into the inner chamber. The inner and outer chambers are supported relative to each other to allow relative movement of these two components in response to changes in the differential temperature between the two components. A rail system slidably supports the inner chamber relative to the outer chamber. The exhaust treatment device comprises a liquid cooled housing surrounding the inner and outer chambers. Exhaust gas is directed through the inner chamber and then into the outer chamber at a closed end of the exhaust treatment device. Exhaust gases then flow through the outer chamber to an exhaust conduit of the marine propulsion system.Type: GrantFiled: March 14, 2002Date of Patent: September 23, 2003Assignee: Brunswick CorporationInventors: Mark A. Ruman, Ronald J. Donahue, David D. Liegeois

Patent number: 6014954Abstract: A slow speed adjustment mechanism is provided that allows an internal combustion engine to be manually adjusted to operate at a slow speed which is slightly faster than the idle speed of the engine. A tubular member is provided with an outer threaded surface and an inner threaded aperture and is rigidly attached to a support plate mounted on the engine. An adjustment head is provided with threads that mate with the threads of the inner threaded aperture of the tubular member. Rotation of the adjustment head moves it axially relatively to an axial end of the tubular member. A flexible shaft can be attached to the adjustment head to allow manual rotation of the adjustment head, whereby the idle speed of the engine can be modified for purposes of trolling or other uses which require a slow operation of the engine at a speed which is slightly greater than its idle speed.Type: GrantFiled: December 19, 1997Date of Patent: January 18, 2000Assignee: Brunswick CorporationInventors: Robert Kleeman, David D. Liegeois

Patent number: 5285751Abstract: An engine air intake screen assembly having a rotating screen is provided. A blade is positioned directly under the screen to scrape accumulated debris off the inside surface of the rotating screen, and to also chop debris flowing through the screen. The screen covers an opening in a blower housing and rotates when the engine is running. In one form, a set screw allows the clearance distance between the blade and the inside surface of the rotating screen to be adjusted.Type: GrantFiled: July 28, 1993Date of Patent: February 15, 1994Assignee: Kohler Co.Inventors: David D. Liegeois, Michael J. Dins, Daniel L. Bakke

Patent number: 4964454Abstract: An evaporable foam pattern for casting a metal air induction manifold for an internal combustion engine. The pattern is formed from an evaporable foam material, such as polystyrene, and in the assembled condition the pattern is in the form of an elongated body member having a generally rectangular cross section. One end of the body member is enclosed by an end wall while the opposite end of the body member is open. One of the side walls of the body member is provided with a plurality of generally parallel slots which are elongated in a lateral direction with respect to the longitudinal axis of the body member. The pattern is composed of a pair of longitudinal pattern sections each being generally U-shaped in cross section and having abutting edges disposed on a parting line. An adhesive joins the abutting edges. The parting line between the pattern section splits the opening in the end of the body member and all of the slots are formed in one pattern section.Type: GrantFiled: December 7, 1988Date of Patent: October 23, 1990Assignee: Brunswick CorporationInventors: James C. Hubbell, Gordon L. Stiller, David D. Liegeois

Patent number: 4907638Abstract: An evaporable foam pattern for producing a cast metal head for a multiple cylinder engine. The assembled pattern includes an elongated block of evaporable foam material having opposed inner and outer faces. A plurality of generally circular head recesses are formed in the inner face and define the cylinder heads in the metal casting. The block is also formed with an internal passage including a group of annular chambers that surround the head recesses and channels interconnect adjacent chambers. The block also has an inlet which communicates with one end of the internal passage and an outlet that communicates with the opposite end of the passage. The pattern is composed of a pair of longitudinal pattern sections having abutted edges that are joined together by an adhesive. The heads, as well as the inlet and outlet, are located in one of the pattern sections, while the two sections in combination define the internal passage.Type: GrantFiled: December 7, 1988Date of Patent: March 13, 1990Assignee: Brunswick CorporationInventors: James C. Hubbell, Gordon L. Stiller, David D. Liegeois
