DEFINITION

Classification: 100/218

(under subclass 214) Apparatus having means to remove the compressed material bodily from a means supporting the material during pressing.

(1) Note. Where one of the pressure surfaces is a piston telescoping within a box, and the piston, by continued motion in the same direction as it moved in the compressing motion, moves the material out of the box, search this class, subclasses 240+ particularly subclasses 244 and 247.

7, for binding machines having means for discharging material from the support which bears the weight of the material during the application of the binding member thereto.

45, for presses having automatic or material triggered control of the displacing of material from the press.

55, for portable receptacle lid applying presses having means to transfer the receptacle from the pressing device.

76+, for presses which form a sheet or web and discharge it so as to wind or fold the sheet. 104+, for presses with drain means for conducting the expressed liquid, particularly 106, for presses having drain means for an expressed liquid or for a liquid pressed from the material during the compacting and having means to propel the liquid.

138, for plural diverse presses in which one press discharges into another press.

144+, for a press which as it presses conveys the material from one opening to another the moving press element usually acting as the conveying and discharging means, particularly

subclasses 152, for an endless conveyor type concurrent pressing and conveying press having means for discharging the material from the conveyor, subclass 173 for a roll type concurrent pressing and conveying press having means for handling or guiding the material, particularly, subclass 174 for such press having means to strip the material from the rolls, and subclass 188 for a plunger type concurrent conveying and compressing press having means for handling the discharge from the press.

196, for plural presses comprising stacked boxes and having means to discharge material from the boxes.

207, for plural presses having means to transfer or discharge the material from one press and place it into the other.

240+, see (1) Note above.
