Adjustable guide for a moving sheet

Claim 1

A device for guiding and controlling an elongated metal sheet of material during its movement comprising a. frame means having a planar guide surface portion; b. track means on the frame means; c. two substantially parallel spaced-apart guide bar elements positioned on the frame means; d. at least one such bar element including spaced-apart track engaging means for relative movement with and guiding by the track means such that the bar is held in a selected orientation from which it is not moved by action of the moving metal sheet; e. each bar element in turn including notched guide means comprising i. a first sheet guide surface positioned to contact a wide surface of the sheet, and ii. a second sheet guide surface positioned adjacent the first surface for guiding an edge surface of the sheet; f. fine-adjustment moving means for moving at least one of such bars independently of the other bar along said track means; and g. clamping means for clamping the movable bar element at a plurality of locations, whereby the planar surface portion and the notched guide means of the guide bar elements are positionable to accomplish guiding of the sheet during its movement.

Claim 2

A device for guiding and controlling an elongated metal sheet of material during its movement comprising a. frame means having a planar guide surface portion; b. track means on the frame means; c. two substantially parallel spaced-apart guide bar elements positioned on the frame means; d. at least one such bar element including spaced-apart track engaging means for relative movement with and guiding by the track means such that the bar is held in a selected orientation from which it is not moved by action of the moving metal sheet; e. each bar element in turn including notched guide means comprising i. a first sheet guide surface positioned to contact a wide surface of the sheet, and ii. a second sheet guide surface positioned adjacent the first surface for guiding an edge surface of the sheet; f. fine-adjustment moving means for moving at least one of such bars independently of the other bar along said track means; and g. clamping means for clamping the movable bar element at a plurality of locations, whereby the planar surface portion and the notched guide means of the guide bar elements are positionable to accomplish guiding of the sheet during its movement.

Claim 4

A device for guiding and controlling a sheet metal material during its movement comprising a. a frame plate having a planar guide surface portion; b. at least two spaced-apart grooves in the frame plate; c. two substantially-parallel guide bar elements, each of said elements in turn comprising an elongated bar, a longitudinal notch therein, and a guide block secure to each end portion of the bar which blocks are adapted to engage with and reciprocate in a groove; d. fine-adjustment moving means for independently moving the bar elements in such reciprocating manner to position the notches adjacent the sheet to be guided; and e. clamping means for clamping the bar elements against the frame plate after such bars have been adjustably moved. a. a frame plate having a planar guide surface portion; b. at least two spaced-apart grooves in the frame plate; c. two substantially parallel guide bar elements, each of said elements in turn comprising an elongated bar, a longitudinal notch therein, and a guide block secure to each end portion of the bar which blocks are adapted to engage with and reciprocate in a groove; d. fine-adjustment moving means for independently moving the bar elements in such reciprocating manner to position the notches adjacent the sheet to be guided; and e. clamping means for clamping the bar elements against the frame plate after such bars have been adjustably moved, said clamping means including at least one deformable clamp element positioned to engage each of the bar elements and pressure means for urging the clamp element against the bars which bars are in turn urged against the frame plate and in which the device has clamp stop means for stopping the clamp element after it has been urged against the bars a selected distance.

Claim 5

A device for guiding and controlling a sheet metal material during its movement comprising a. a frame plate having a planar guide surface portion; b. at least two spaced-apart grooves in the frame plate; c. two substantially-parallel guide bar elements, each of said elements in turn comprising an elongated bar, a longitudinal notch therein, and a guide block secure to each end portion of the bar which blocks are adapted to engage with and reciprocate in a groove; d. fine-adjustment moving means for independently moving the bar elements in such reciprocating manner to position the notches adjacent the sheet to be guided; and e. clamping means for clamping the bar elements against the frame plate after such bars have been adjustably moved. a. a frame plate having a planar guide surface portion; b. at least two spaced-apart grooves in the frame plate; c. two substantially parallel guide bar elements, each of said elements in turn comprising an elongated bar, a longitudinal notch therein, and a guide block secure to each end portion of the bar which blocks are adapted to engage with and reciprocate in a groove; d. fine-adjustment moving means for independently moving the bar elements in such reciprocating manner to position the notches adjacent the sheet to be guided; and e. clamping means for clamping the bar elements against the frame plate after such bars have been adjustably moved, said clamping means including at least one deformable clamp element positioned to engage each of the bar elements and pressure means for urging the clamp element against the bars which bars are in turn urged against the frame plate and in which the device has clamp stop means for stopping the clamp element after it has been urged against the bars a selected distance.
