Abstract
An air filter includes a base member, a filter element, a connector for connecting the base member to a support, and releasable securing members for releasably securing the filter element to the base member. When the securing members are released, the filter element is removable from the base member while the base member remains connected to the support.
Claims18
An air filter adapted for being mounted adjacent to a carburetor of an internal-combustion engine, said air filter comprising:
- (a) a base defining a central air-inlet opening therein for communicating with the carburetor, and including base attachment means for permanently attaching the base to the engine without substantially obstructing the air-inlet opening to the carburetor;
- (b) a removable filter element comprising a filter support frame positioned on the base, and a filter medium carried by the support frame and surrounding the air-inlet opening to the carburetor for filtering an air stream passing through the air filter to the carburetor;
- and
- (c) a plurality of releasable securing means spaced-apart along respective engaging surfaces of the filter support frame and the base, and cooperating to releasibly secure the filter element to the base, said releasable securing means operating independent of the base attachment means such that the filter medium is readily removable and replaceable without detaching the base from the engine.
