Heel-pol′ish-ing ma-chine′.
（
Shoemaking.) One for smoothing the surface of a heel after it is shaped and trimmed.
There are several modes.
1. In the
Ellis and
Glidden machine, trimming and burnishing devices, actuated by a lever, move around the surface of the heel, guided by a plate having the form of the finished heel.
2. The boot is jacked and is revolved against a rotating burnisher, as in Fig. 2487.

3. The boot is clamped to the sliding frame, and the polisher reciprocated over the surface of the heel by an eccentric, whose rod is connected to the oscillating arm. (
Fig. 2488.)

4. The boot is jacked, the arm
b (
Fig. 2489) reaching down the boot-leg and holding the heel to its seat.
The heel is held up to the polisher, and the edge of the heel against the polisher-flange, which prevents the outer lift from spreading away at its edge while the jack is being rocked to bring the whole edge of the heel under the action of the stationary polisher.
