Abstract
A transverse appendage is spring biased into contact with a protuberance equipped platform. The platform protuberances act as detents impending arcuate travel of the transverse appendage. Tabs extending upwardly from the platform positively limit the arcuate travel of the transverse appendage.
Claims7
A detent mechanism comprising:
- a fixed detent platform having an aperture therethrough, first and second upwardly extending tabs and first and second protuberances formed in said detent platform on arcuate paths between said tabs;
- a rotatable control rod passing through said aperture of said detent platform, said control rod having a transverse appendage extending outward from said control rod in contact with the top surface of said detent platform between said first and second upwardly extending tabs;
- a biasing means carried on said control rod to urge said transverse appendage into contact with the detent platform whereby said first and said second tabs absolutely limit the arcuate travel of said control rod through contact with said transverse appendage and said first and second protuberances impede the arcuate travel of said control rod through spring loaded contact with said transverse appendage.
A detent mechanism comprising:
- a fixed detent platform having an aperture therethrough, first and a second upwardly extending tabs, and first and second protuberances formed in said detent platform on different arcuate paths between said tabs;
- a platform bracket and guide having an aperture therethrough grounded to provide a firm mounting for said detent platform;
- a rotatable control rod passing through said aperture of said detent platform and said aperture of said platform bracket and guide, said control rod having a transverse appendage extending outward from said control rod in contact with the top surface of said detent platform between said first and second upwardly extending tabs;
- a collar fitted around the lower portion of said control rod and fixed to said control rod by means of the pin through the collar and the control rod;
- a forward-reverse bell crank fixedly attached to said collar;
- a biasing means carried on said collar urging said transverse appendage into contact with the detent platform whereby said first and second tabs absolutely limit the arcuate travel of said control rod through contact with said transverse appendage and said first and second protuberances impede the arcuate travel of said control rod through spring loaded contact with said transverse appendage.
