Abstract
Abstract An industrial machine press having multiple post structures providing an open work receiving and forming area freely accessible from three sides without obstruction, utilizes some of the structural posts for the additional function of guiding a movable upper platen. All posts during pressing operations are sustaining either tension or compression loads without the creation of bending stresses in them. Their lower portions are rigidly mounted to a stationary platen and its supporting structure, and their upper portions are less rigidly mounted to upper positioning structure. Preferably all posts are equally sized and placed to withstand similar loadings, being grouped, as necessary, to supplement one another and remain free of bending stresses thereby assuring the upper and lower platens remain parallel to one another at all times. An embodiment particularly directed to fully utilizing posts sized and placed to withstand similar loadings, has six posts, with four in tension and two in compression.

Total Claims: 19
Claim 1
Independent Claim
260 words
An industrial machine press, freely and continuously accessible for loading from three main directions to apply force to work pieces by using compressing platens which remain parallel during compression operations, while held and guided by support posts, which in turn, join top and bottom frame structures of this industrial machine press, as the posts are mounted to remain free of bending stresses, being able only to assume either compression or tension loads, comprising: a. a bottom frame structure; b. a lower stationary compressing platen secured to the bottom frame structure; c. support posts rigidly supported at their lower portions on the bottom frame structure and positioned to receive respectively compression and tension loads; d. a top frame structure held substantially stationary except for resilient distortions occurring during compression of the work piece as it less rigidly receives and positions the upper portions of the support posts so they will not assume any bending stresses; e. a movable compressing platen structure guided on and slidably supported along at least two of the support posts which serve the dual functions of sustaining tension loads and guiding this movable compressing platen, said support posts being arranged between the bottom and top frame structure along one side of the compressing platens in respective parallel rows leaving the working area freely and continuously clear on three sides to receive the work piece to be formed and f. power means secured between the top frame structure and the movable compressing platen to selectively move the movable compressing platen in relation to the lower stationary compressing platen.

Claim 3
Dependent Claim
72 words
An industrial machine press, as claimed in claim 1, wherein the support posts arranged between the bottom and top frame structures are in respective rows where all posts in a given row sustain respectively tension loads from the bottom and top frame structures when located near the compressing platens and compression loads when located far enough away from the compressing platens to receive compression forces from the bottom and top frame structures.
Claim 4
Dependent Claim
93 words
An industrial machine press, as claimed in claim 2, wherein the support posts are arranged in groups in which each support post of a group sustains like type loading during pressing operations on a work piece, the group located nearest the compressing platens undergoing tension loads and comprising a larger number of support posts to share the overall tension loading at this locale, and the group located farther away from the compressing platens undergoing compression loads and comprising a smaller number of support posts to share the overall compression loading at this locale.
Claim 5
Dependent Claim
28 words
An industrial machine press, as claimed in claim 3, wherein all of the support posts are undergoing unit stresses of similar magnitude and are therefore of equal size.
Claim 6
Dependent Claim
69 words
An industrial machine press, as claimed in claim 1, wherein the support posts are supported at their lower portions by the bottom frame structure along a greater part of their overall length and at their upper portions by the top frame structure along a lesser part of their overall length to obtain the respective rigid and less rigid supports and thereby eliminate any bending stresses in these support posts.
Claim 7
Dependent Claim
32 words
An industrial machine press, as claimed in claim 1, wherein the support posts are shouldered at their upper and lower portions to establish the spacing between the top and bottom frame structures.
Claim 8
Dependent Claim
58 words
An industrial machine press, as claimed in claim 6, wherein the support posts are threaded beyond their shouldered portions and extended beyond the top and bottom frame structures where nuts are threaded on them in assembling the press and secured to insure the parallelism of the compressing platens during all the subsequent pressing operations on a work piece.
Claim 9
Dependent Claim
39 words
An industrial machine press, as claimed in clAim 7, wherein resilient washers are fitted around the support posts, underneath the nuts, and above the top frame structure, to further insure the support posts will not sustain any bending stresses.
Claim 10
Dependent Claim
