Abstract:

An apparatus for identifying the optimum jet for a carburetor which includes a general annular first member having a plurality of first graduations disposed about a peripheral portion thereof, a general arcuate second member having a plurality of second graduations disposed for cooperation with the first graduations, and members coupling the first and second member permitting relative rotation and selective alignment of the first and second graduations. One of the plurality of graduations are arrayed on a linear scale corresponding to relative air density and the other of the plurality of graduations being arrayed on a scale corresponding to respective jet flow and or identifying numbers. The members coupling the first and second members may include a plurality of arms disposed at angularly space intervals. There may be three such arms and they may be fixed to the arcuate member.

Abstract:

A reed for use in a reed valve which includes a resilient planar member having a first edge portion by which the member may be attached to an associated reed cage and an opposed second edge portion. The reed includes a generally arch shaped cut in the member defining in the member spaced hinges extending generally intermediate the first and second edge portions on each side of the arch shaped cut and also defining a portion within the member that opens upon bending of the member intermediate the first side and the second side. In some forms of the invention the generally arch shaped cut has two ends and the two ends are closer to the second edge portion than the remainder of the generally arch shaped cut. Some embodiments of the invention may have a plurality of additional generally arch shaped cuts disposed therein. Each of the generally arch shaped cuts has two ends and the two ends of each generally arch shaped cut are disposed closer to the second edge portion than the remainder of the generally arch shaped cut.
