Abstract
Abstract A high capacity press includes a fixed foundation and a frame which is movable in respect to the foundation by a fluid pressure operated drive comprising a cylinder and plunger movable in the cylinder. Each frame is made up of a plurality of plates arranged in a stack, the plates being either of a closed frame forming configuration or made up of two oppositely arranged C-shaped plates oriented with their legs abutting to form a closed frame. A guide system for the frames is carried on the foundation and engaged with the frame or guiding the frame during its movement and includes an upper guide of substantially T-shaped configuration which extends transversely between adjacent frame elements and bears against the frame in at least two planes and a lower guide comprising elements which extend radially outwardly from the drive cylinder and engage the frame in at least two separate radial planes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A frame construction of a high-capacity subfloor press comprising a fixed foundation column, a press drive cylinder connected to said column, a moving press frame including a minimum of two parallelly arranged plate stacks that mutually support one another and are interconnected and positively guided in relation to said fixed foundation column and said press drive cylinder, a guide system for said moving press frame comprising an upper supporting guide arranged laterally adjacent the top of said foundation column and protruding into said movable press frame and being effective in two planes and a lower radial supporting guide arranged in the vicinity of said press drive cylinder and supported on said press frame and being effective in two planes, said top guide comprising a plurality of supporting elements arranged parallel to the press axis and connected laterally to the foundation column, each said supporting element protruding between two neighboring plate stacks and forming with at least one end face and side faces a two-plane support for said moving frame.
Claim 2
Dependent Claim
169 words
A frame construction of a high-capacity subfloor press comprising a fixed foundation column, a press drive cylinder connected to said column, a moving press frame including a minimum of two parallelly arranged plate stacks that mutually support one another and are interconnected and positively guided in relation to said fixed foundation column and said press drive cylinder, a guide system for said moving press frame comprising an upper supporting guide arranged laterally adjacent the top of said foundation column and protruding into said movable press frame and being effective in two planes and a lower radial supporting guide arranged in the vicinity of said press drive cylinder and supported on said press frame and being effective in two planes, said top guide comprising a plurality of supporting elements arranged parallel to the press axis and connected laterally to the foundation column, each said supporting element protruding between two neighboring plate stacks and forming with at least one end face and side faces a two-plane support for said moving frame.
Claim 3
Dependent Claim
139 words
A high capacity press comprising a fixed foundation, a press frame movable in respect to said foundation, a fluid pressure-operated drive connected between said frame and said foundation for moving said frame relative to said foundation and including a cylinder carried by one of said frame and said foundation and a piston carried by the other of said frame and said foundation, said frame and said foundation defining a work-supporting table and a counter pressure surface therebetween, said frame comprising a plurality of stacks of vertically arranged plates and means for securing said plates in an assembled orientation; a top guide bearing against and supporting said frame in at least two separate planes, and a bottom guide extending radially outwardly from said press cylinder and bearing against and supporting said frame in at least two oppositely directed plane surfaces.
Claim 4
Dependent Claim
139 words
A high capacity press comprising a fixed foundation, a press frame movable in respect to said foundation, a fluid pressure-operated drive connected between said frame and said foundation for moving said frame relative to said foundation and including a cylinder carried by one of said frame and said foundation and a piston carried by the other of said frame and said foundation, said frame and said foundation defining a work-supporting table and a counter pressure surface therebetween, said frame comprising a plurality of stacks of vertically arranged plates and means for securing said plates in an assembled orientation; a top guide bearing against and supporting said frame in at least two separate planes, and a bottom guide extending radially outwardly from said press cylinder and bearing against and supporting said frame in at least two oppositely directed plane surfaces.
Claim 5
Dependent Claim
46 words
A press, according to claim 2, wherein said bottom guide includes a claw member extending radially outwardly from each side and each end of said press cylinder and bearing against leg portions of said frame on each side of said cylinder from two opposite radial sides.
Claim 6
Dependent Claim
36 words
A press, according to claim 2, wherein said press cylinder is secured to said foundation said press plunger having its lower end secured to said frame and being displaceable in said cylinder for moving said frame.
Claim 7
Dependent Claim
95 words
A higH capacity press, comprising a fixed foundation, a frame movable in respect to said foundation, drive means connected between said frame and said foundation for moving said frame relative to said foundation, and a guide system carried on said foundation and engaged with said frame for guiding said frame in its movement including a first supporting guide extending laterally into said frame and bearing against said frame in at least two separate planes and a second guide spaced from said first guide on said foundation and extending radially into bearing engagement with said frame.
Claim 8
Dependent Claim
95 words
A higH capacity press, comprising a fixed foundation, a frame movable in respect to said foundation, drive means connected between said frame and said foundation for moving said frame relative to said foundation, and a guide system carried on said foundation and engaged with said frame for guiding said frame in its movement including a first supporting guide extending laterally into said frame and bearing against said frame in at least two separate planes and a second guide spaced from said first guide on said foundation and extending radially into bearing engagement with said frame.
Claim 9
Dependent Claim
63 words
A high capacity press, according to claim 5, wherein said frame is mounted in said first and second supporting guides for vertical movement, said first supporting guide comprising a top guide said second supporting guide comprising a bottom guide and bearing against and supporting said frame in at least two radial planes, said frame comprising a plurality of stacks of vertically arranged plates.
Claim 10
Dependent Claim
69 words
A high capacity press, according to claim 6, wherein said top guide comprises a substantially T-shaped supporting element carried on said foundation and engaged with said frame between adjacent stacks, said frame carrying supporting plates between stacks with correspondingly T-shaped recesses engaged and bearing against the T-shaped projection of said guide elements, the end faces of said T-shaped elements forming a two plane support for said moving said frame.
Claim 11
Dependent Claim
40 words
