DEFINITION

Classification: 100/214

(under the class definition) Means including opposed pressure surfaces and means moving at least one of the surfaces to cause it to approach the opposing surface to compress material therebetween.

SEE OR SEARCH THIS CLASS, SUBCLASS:

116, for presses with drain means for expressed liquid along or through a pressure surface and the surface is a movable piston or platen.

141, for plural diverse presses in which at least one of the presses conveys while pressing and such press is loaded by a transversely moving platen or packer.

178, for concurrent pressing and conveying presses in which the conveying is by means of a moving compression chamber and the compression involves a piston or platen type press.

179, for plunger type concurrent pressing and conveying presses. SEE OR SEARCH CLASS

15, Brushing, Scrubbing, and General Cleaning,

261, for mop wringers in which the mop is squeezed between flat boards or plates.

29, Metal Working,

251, for assembling and disassembling apparatus having means for engaging two work parts to be assembled or disassembled and means for multiplying the force input to the apparatus where the apparatus is of the arbor press type.

34, Drying and Gas or Vapor Contact With Solids,

143+, for apparatus for removing liquid from material in which the material to be treated is held between two opposed members which are movable or expansible toward one another to press or retain the material, and away from each other to release the material.

38, Textiles: Ironing or Smoothing,

17+, for smoothing machines wherein the work is smoothed between platens, and subclass 71, for implements involving simple elemental devices for effecting pressure between the platens.

65, Glass Manufacturing,

305+, for a press molding machine; see the "Search Notes" thereunder.

68, Textiles: Fluid Treating Apparatus, 113+, for squeezing machines for squeezing textiles while subjected to a only of a pair of members between which the pressure is effected, is moved and, subclasses 241+, for wringers for removing the liquid from textiles by pressing.

69, Leather Manufactures,

48, for apparatus for treating leather in which opposing forces are brought to bear upon the leather which tend to compress the leather.

83, Cutting,

523+, and particularly subclasses 531+, indented thereunder, for a clicker die press or other device having a reciprocable tool or platen.

99, Foods and Beverages: Apparatus,

557+, and 559+, for punch type seed removers; and subclasses 572+, and 577-583, for shell separators having presser members.

101, Printing,

134.5, for bed and platen copying apparatus having opposed members capable of relative movement toward each other to make the impression by nonrolling contact where there is a printing surface bearing designs in ink of such nature as not to require reinking and subclasses 287+, for machines comprising two opposing pressure members so constructed as to contact simultaneously at all points with the work held therebetween thereby effecting a nonrolling impression.

131, Tobacco,

111+, for apparatus for making tobacco plugs of compressed shapes. 144, Woodworking,

256.1+, for machine for bending wood to desired form by compressing it between formers or dies.

164, Metal Founding,

169+, for sand compacting mold making means and, particularly subclasses 207+, for press type compactors.

222, Dispensing,

386, for dispensing containers having a follower type discharge assistant.

269, Work Holders,

86+, for patents to a device with relatively movable jaws to grip an object while being treated. See section VIII under the class definition of Class 269 for the line with respect to Class 100.

384, Bearings,

7+, for linear bearings.

410, Freight Accommodation on Freight Carrier,

121+, e.g., for squeeze-type brace structures of indented subclass(es) 123+, and the wall-to-lading structures of indented subclass 128 in which a brace structure applies pressure against lading on a freight carrier.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

394+, for a preform reshaping or resizing means or vulcanizing means compressing coacting press surfaces, and subclasses 406+, for means shaping a mass comprising opposed press members; see the search notes thereunder.

452, Butchering,

144, for meat tenderers having plates provided with projections to mash the meat therebetween.
