(under subclass 82) Implement having means to releasably secure the advancing means in a desired position along its path.
(1) Note. The latch restrains the advancing means positively, i.e., it prevents both forward and rearward movement, and it must be released to allow movement of the advancing means in either direction. The latch may include, for example, a detent to engage the actuator or means to increase and to diminish the friction between said advancing means and a stationary part of the implement.
(2) Note. A patent to a coating implement with advancing means for a piece of solid material and which includes resilient means to continually resist movement of a piece of material in either direction will be placed in subclass 80.
(3) Note. A device which allows one way movement of an actuator and jams or otherwise prevents reverse movement of the actuator or the piece of coating material is not considered a latch but a retrograde-movement preventer as provided for in subclass 84, herebelow.
SEE OR SEARCH THIS CLASS, SUBCLASS:
80, for a solid coating material implement with means to advance material and resilient braking means; and see (2) Note above.
84, for an implement including manually actuated advancing means and a retrograde-movement preventer; and see (3) Note above.
