The most interesting modification of Keyes's Turntable Apple Parer is the use of a split-frame design to "pull" the pared apple off the fork. The
overall turntable motion is similar to the Keyes; however, the turntable
has an incline or cam that pushes the fork
apparatus, which is a first class lever, away from the frame. As the fork is pushed back, the
apple hits the frame and is loosened from the fork for easy removal.
The fork gear must
be disengaged and re-engaged smoothly for this frame movement to occur.
Three different variations of the split-frame design are known (Thornton, 1997). All three variations carry William Robb's patent date of November 22, 1870 for his split-frame innovation (Robb, 1870). Robb's split-frame mechanism is illustrated on an arc parer in his letters patent. Goodell did manufacture the arc split-frame. While all three split-frame turntable designs are embossed manufactured by Lockey & Howland they were in fact manufactured by Goodell.

the two Split-Frame push-offs.
Goodell's final split-frame design, pictured above, utilizes a tilted frame to
prevent clogging from parings. This parer is marked PATENTED JUNE 17 & DEC.
