Abstract: A connection assembly for an exhaust extraction system which is designed to vent the exhaust from a vehicle tail pipe includes, in combination, three primary components. The first component is an annular sleeve which is constructed and arranged to assemble onto the vehicle tail pipe. A band clamp is used for this connection in order to establish a leak-free interface. Next, there is a nozzle locator ring which slides onto the annular sleeve such that one end of the sleeve extends beyond one side of the nozzle locator ring and the opposite end of the sleeve extends beyond the opposite side of the nozzle locator ring. There is an offset portion intermediate the ends of the annular sleeve which serves as an abutment for the nozzle locator ring.

Abstract: A latching mechanism for attachment to a boat trailer and for securely latching onto the U-bolt typically found on a boat bow includes an integral weldment providing a pair of oppositely-disposed side plates and a cooperating support plate positioned therebetween. Assembled to the side plates are a pair of alignment cones which help to guide and direct the bow of the boat and in particular the U-bolt into the latching mechanism. The support plate defines a receiving channel having a closed base and an open entrance. A pair of spring-biased latching jaws are pivotally attached to the support plate on opposite sides of the receiving channel and are normally positioned in a closed and latching condition. Each latching jaw includes a tip portion and the two tip portions are oriented so as to extend inwardly toward each other and across the open end of the receiving channel.

Abstract: A magnetically-attached exhaust nozzle assembly for use as part of an exhaust extraction system for a fire truck includes an annular nozzle locator ring which is designed to slide over and secure to the exhaust pipe of the fire truck. The nozzle locator ring includes an inner sleeve which fits closely against the outside diameter of the exhaust pipe and an outer sleeve which receives a flexible exhaust nozzle. The exhaust nozzle is integrally connected with a flexible hose of the extraction system and establishes sealing engagement at two locations on the nozzle locator ring. There is axial sealing by abutment up against a flange of the nozzle locator ring and circumferential or radial sealing due to the fit of the nozzle on the outside surface of the outer sleeve. The flexible exhaust nozzle includes a guide rail which helps with the initial alignment and a magnet housing which ultimately attaches by magnetic attraction to the surface of the exhaust pipe for securely holding the nozzle in position.
