DEFINITION

Classification: 83/447

(under subclass 446) Device in which the movable or yieldable guide element tends to hold moving work in contact with a work-table or other supporting element or assemblage.

(1) Note. The devices found here and in subclass 450 are frequently called "holddowns". They differ from clamps in that they are not actuated manually or by power means, and in that they do not immobilize the work.

(2) Note. A holddown which is claimed as of utility in freeing a tool from work after a cutting operation (i.e., from product) will be found in subclass 145.

SEE OR SEARCH THIS CLASS, SUBCLASS:

145+, for means to move product out of contact with a tool; and see (2) Note, above.

450, for a nonyieldable holddown.

452+, for work clamping means associated with a cutter.
