DEFINITION

Classification: 12/115.6

(under subclass 114.2) Shoe stretcher provided with means for changing the amount of the stretching action or the size of the base from which the stretching action takes place.

(1) Note. The variable stretching action may be permitted by a spring which acts to give the stretching part its movement or by an adjustable connection which would permit the stretcher to be used in shoes of varying sizes.
