Abstract
A selectively removable exhaust baffle which can be placed within an exhaust pipe to muffle the emitted sound. The removable baffle preferably includes a frame having a pair of legs joined by a spring portion. One or more transverse occluding plates are mounted on the frame. The frame is sized so that when it is pushed into the exhaust pipe it must be compressed. This compression holds the frame in place. The transverse occluding plate or plates lie against the interior wall of the exhaust pipe. The gas flow must therefore pass around the plate or plates, thereby attenuating the sound.
Claims21
A method for selectively attenuating the sound produced by an exhaust pipe having an internal diameter and a central pipe axis, comprising:
- a. providing a removable baffle including,
- i. a first leg,
- ii. a second leg,
- iii. a spring portion connecting said first and second legs, said spring portion being configured to urge said second leg pivotally away from said first leg to form a V-spring having a pivot axis,
- iv. an occlusion plate, attached to said first leg, said occlusion plate including a circular portion sized to fit against said internal diameter of said exhaust pipe, and
- v. said V-spring being sized such that said second leg must be compressed toward said first leg in order to slide said removable baffle into said internal diameter;
- b. orienting said removable baffle so that said pivot axis is perpendicular to said central pipe axis;
- c. compressing said second leg toward said first leg while sliding said removable baffle into said internal diameter;
- and
- d. sliding said removable baffle sufficiently far into said exhaust pipe so that said occlusion plate lies within said exhaust pipe and impedes the flow of gas through said exhaust pipe.
(canceled)
A method for selectively attenuating the sound produced by an exhaust pipe having an internal diameter and a central pipe axis, comprising:
- a. providing a removable baffle including,
- i. a first occlusion plate attached to a first leg,
- ii. a second occlusion plate attached to a second leg,
- iii. a spring connecting said first and second legs, said spring being configured to urge said first and second legs pivotally away from each other to form a V-spring having a pivot axis, and
- iv. said removable baffle being sized such that said V-spring must be compressed in order to slide said first and second occlusion plates into said internal diameter;
- b. orienting said removable baffle so that said pivot axis is perpendicular to said central pipe axis;
- c. compressing said second occlusion plate toward said first occlusion plate while sliding said removable baffle into said internal diameter;
- and
- d. sliding said removable baffle sufficiently far into said exhaust pipe so that said first and second occlusion plates lie within said exhaust pipe and impede the flow of gas through said exhaust pipe.
