Abstract: My invention relates to a treadle mechanism to which I have designed with special reference to the requirements of a dental engine or lathe, but which is applicable also to other machines designed to be operated by foot-power. It consists in providing the treadle with an elevating-spring, which partly raises the treadle and tends to keep the crank off the center, and in combining therewith a fly or driving wheel slightly out of balance, so that the wheel will tend to come to rest at a point where the treadle will be partly raised, and the crank will be to that side of the center where it should be, in order to insure that the wheel shall start in the proper direction. It also consists in the means hereinafter described for mounting the free end of the spring upon the guide on or over which that end moves when the treadle oscillates. Claim: The combination, with the treadle mechanism, of a spring for raising, the treadle and a fly or driving wheel slightly out of balance.
