DEFINITION

Classification: 254/50.1

RESILIENT TIRE-CASING SPREADERS:

(under the class definition) Apparatus comprising means for engaging and applying force either to spread apart or to press together the beads or side walls of resilient tire casings.

(1) Note. The spreading apart of the beads is usually disclosed as opening the interior of the casing for inspection, while the pressing together of the side walls is usually disclosed as opening up surface defects in the tread portion of the casing.

(2) Note. The "means for engaging and applying force" referred to in the definition is to be construed as excluding devices which merely hold the tire casing in deformed position. See Class 81, Tools, subclass 15.3 for such devices. Tire spread holders which are provided with means adapting the device to use also as a spreader are provided for in this or the indented subclasses.
