Abstract: An extension bracket for a slider bar comprising a first curved tubular member affixed to a first end of a slider bar and a second end extending below the slider bar, spaced from a wall of a tractor unit. A second curved tubular member is affixed to a second end of the slider bar and a second end extending below the slider bar, spaced from the wall. There is a tubular cross member affixed to a portion of the first curved member to a portion of the second curved member. There is a tubular mounting member having first and second ends connected, respectively, to the second end of the first curved tubular member and to the second end of the second curved tubular member. The tubular mounting member also has a mid-section between the first and second end sections which is in contact with the wall of the tractor unit.

Abstract: A gladhand assembly having a conduit for carrying a fluid and a port having a sidewall defining an interior region. The port also having a first opening in communication with an external environment and a second opening in communication with the conduit. The port includes a first recess in the interior region and disposed in the sidewall. There is a filter member including a sidewall and a first opening including a rim. The rim extends outwardly from the sidewall in a radial direction and is seated on the first recess in the sidewall of the port. There is a seal member configured to engage with and close the first opening in the port and the seal member includes a film having a first surface facing the external environment and a second surface facing the interior region of the port. The film includes a re-closable aperture.

Abstract: A skylight assembly for installation in a vehicle wall includes a lens body having an exterior surface and a cap connected to an end of the lens body and a lens flange. There is a nut member to secure the lens body. A gasket is disposed between the lens member and the vehicle wall and includes a first leg portion and a second leg portion. The first leg portion extends into a recess between a surface of an aperture in the wall and the exterior surface of the lens body and the first leg portion has a uniform thickness which is less than a width of the recess thereby forming a gap. The second leg portion extends from the first leg portion substantially at a right angle and is disposed between and in contact along its length with the lens flange and the exterior of the wall about the aperture.

Abstract: A grip and fitting assembly for coupling an air hose to a gladhand coupler. The grip is flexible and tapered with a tubular interior through which may pass a length of hose shielded and protected by the grip. The grip is affixed to a fitting attachable to the gladhand coupler on a first threaded end thereof and attachable to the air hose on a second barbed end thereof. The grip is configured with one or more internal keyway boss which aligns and interlocks with one or more corresponding keyway recess on a retaining shoulder formed between the ends of the fitting.

Abstract: A swivel coupling assembly includes a first annular member having at least one annular barb, a shoulder and at least one annular groove containing a seal. There is a first bearing surface and a second bearing surface either side of the annular groove. The first and second bearing surfaces have a width equal to or greater than a width of the annular groove. There is a second annular member having an inner surface defining a bore configured to receive the first annular member. When joined, the shoulder of the first annular member frictionally engages the bore of the second annular, thereby allowing rotation. The seal engages with and seals the bore at a location between the ends of the second member. and spaced by a distance of at least the width of the first and second bearing surfaces from the shoulder and the second opening, respectively.
