DEFINITION

Classification: 226/120

(under the class definition) Device having means for advancing material in a step-by-step manner, including advancing an increment of material and stopping movement of the material.

SEE OR SEARCH THIS CLASS, SUBCLASS:

8, for an analogous method.

115+, for an intermittent mover cooperating with another material mover.

SEE OR SEARCH CLASS

40, Cards, Picture, or Sign Exhibiting,

342+, for a copy holder including means to advance a web of copy intermittently; particularly, subclass 346 for such a copy holder including a cyclically acting actuator for rotary-pinch-pair advancing means. 53, Package Making,

235+, for apparatus for depositing strips or rods in preformed receptacles.

74, Machine Element or Mechanism,

111+, for an intermittent grip type mechanical movement and subclasses 144+ for grip units and features.

83, Cutting,

202+, for similar mechanism combined with cutting means.

198, Conveyors: Power-Driven,

750+, for a conveyor having to and fro movements which carry material a distance and then return for another hold on the same material.

221, Article Dispensing, appropriate subclasses for a device for dispensing or feeding articles from a source of supply to a point of use, and not otherwise provided for; and see the class definition of Class 221 for a statement of the class lines and for the disposition of other related article feeding disclosures.

225, Severing by Tearing or Breaking,

10+, for a device which feeds out a predetermined amount of material to a manual tearing edge. 227, Elongated-Member-Driving Apparatus,

82+, for a device for applying a member e.g., nail to work combined with means for forming the member and having means for feeding and cutting a blank from which the member is made.

242, Winding, Tensioning, or Guiding, for more than a nominal supply or take-up coil structure (e.g., a support for such a coil, a cooperative relationship between a tension or exhaust detector and reel driving or reel stopping means, etc.),

354, for a particular linear feeder* (e.g., capstan or sprocket, etc.) spaced from the supply or take-up coil.

314, Electric Lamp and Discharge Devices: Consumable Electrodes, appropriate subclasses, especially

82, 128 for an arc lamp or other similar electric discharge device which is provided with means for feeding an electrode (rod, bar, or tube) into position as the electrode is consumed, where the feeding mechanism includes an intermittent grip mechanism.

401, Coating Implements With Material Supply,

65+, for an implement including means to feed a rod of solid coating material incrementally.

414, Material or Article Handling,

14+, for devices for moving stock by means of lead-end pullers or end face pushers.

470, Threaded, Headed Fastener, or Washer Making: Process and Apparatus,

162+, for feeding of work blanks of stock pieces not provided for in the several machining classes and yet so specialized to the functions of a machining class as to preclude classification in a general article feeding or dispensing class (221). See the reference to Class 221 hereinbelow.
