(under subclass 266) Device having an internal-resistance motion-retarder placed in an appropriate subclass of 266+ and also relying for its motion-retarding effect upon the friction characteristics of two adjacent surfaces, which second motion-retarding effect is characteristic of devices placed in other subclasses of Class 188.
(1) Note. This subclass includes (a) a device wherein a brake of subclass 290 or its indented subclasses is combined with a friction brake of other subclasses of Class 188, and (b) a device wherein a shock absorber of subclass 297 or its indented subclasses is particularly disclosed as having its retarding effect increased by friction (e.g., the cylindrical surface of a piston is radially urged against the cylinder in which the piston slides).
