A modular raceway system for any combination of high voltage power lines and low voltage data communication lines uses a combination hinge-latch cover member and a single piece base member. The system incorporates an elliptical profile and eliminates conventional sidewalls, and presents the hinge-latch mechanism to releasably secure a cover member in a snap-lock manner to the base member.

Multi-channel raceway

Raceway fitting

A flexible strap has a locking head and a free end. The strap is received in a passage in the locking head where it is engaged by a locking tab which is biased toward engagement with the strap as it passes into and through the passage. The locking tab prevents withdrawal of the tie from the locking head. The strap can be released for withdrawal from the locking head by moving the tab against the bias. An opening is provided in the locking head generally opposite to the location of the locking tab. The strap, throughout the major portion of its extension, has a width which is less than the width of the opening. The opening in the locking head is preferably provided with spaced shoulders in the area of the engagement between the locking tab and the straps serrations. An inclined lip is provided in the area through which the strap exits the locking head. The lip is angled such as to displace the strap from the normal exterior of the strap.

Parallel entry tie

A carburetor assembly which has a body formed of extruded aluminum and a plastic fuel bowl assembly secured to the body by means of a resilient spring clip. A gasket is located between the body and the fuel bowl. The fuel bowl is molded of plastic and includes an integral well, and a mixing screw housing as well as a primer housing. A plastic nozzle extends from the well through the venturi insert into a through passage into the body. The venturi insert is made of plastic material and includes molded grooves therein which form passages with the through passage of the body. The nozzle is resiliently urged against the gasket and the body by means of a spring located in the well thereby sealing the nozzle to the body.

Carburetor assembly

A vented fuel cap adapted to be removably attached to a filler neck of a fuel tank of the type commonly employed with small internal combustion engines is provided. The vented fuel cap comprises generally a generally cylindrical cap that is formed with inner threads, and is adapted to be threadedly engaged with the filler neck. A liner element is provided to fit within the cap, and is seated along the underside of the top of the cap. The liner element includes an axially inwardly-directed dome-shaped diaphragm portion that includes a slit formed substantially in its center. The cap and liner element allow for bi-directional venting of the fuel tank. The inwardly-directed dome-shaped diaphragm portion of the liner element allows outside air to vent into the fuel tank at a considerably smaller pressure differential than that required to vent outwardly from the interior of the tank.

Anti-leak fuel cap liner

A method of making a carburetor by first extruding a length of material and then cutting a carburetor body of predetermined length from the extrusion. The extrusion includes a passageway. A venturi member is molded of plastic material and inserted in the passageway. A fuel bowl is molded from plastic material and is secured to the body by means of a resilient clip.
