Claim 6

In a machine as recited in claim 1, wherein said means mounting said supporting rails and said means mounting said guiding rails are all adjustable, whereby to provide for establishing a precision parallel relationship among said rails.

Claim 7

In a machine, a bed for reciprocably carrying a moveable machine element, said bed including a generally horizontal supporting surface, and a pair of spaced upright frame members disposed on opposite sides of said supporting surface; at least one cylindrical supporting rail; means mounting said supporting rail on said supporting surface to extend longitudinally thereof, said mounting means being adjustable for adjusting the position of said supporting rail; a pair of cylindrical guiding rails; means mounting said cylindrical guiding rails on said upright frame members, said means being adjustable for adjusting the position of said guiding rails, and the axes of said supporting and said guiding rails all being parallel to each other; a moveable machine element received between said supporting rail and said guiding rails; a supporting bearing means carried by said machine element and resting on said supporting rail, said supporting bearing means being in contact with the upper surface of said supporting rail for a substantial linear distance; first lubrication housing means enclosing said supporting bearing means and engaged with said supporting rail; two vertical guide bearing means carried on the upper portion of said moveable element, said vertical guide bearing means each being in contact with the underside of one of said guiding rails for a substantial linear distance; two horizontal guide bearing means mounted on the upper, opposite end portions of said moveable element, said horizontal guide bearing means each being in contact with the inner side of one of said confronting guiding rails for a substantial linear distance; second lubrication housing means enclosing said vertical and said horizontal guide bearing means and in engagement with said guiding rails; and means for supplying liquid lubricant to said first and said second lubrication housing means.

Claim 8

In a machine, a bed for reciprocably carrying a moveable machine element, said bed including a generally horizontal supporting surface, and a pair of spaced upright frame members disposed on opposite sides of said supporting surface; at least one cylindrical supporting rail; means mounting said supporting rail on said supporting surface to extend longitudinally thereof, said mounting means being adjustable for adjusting the position of said supporting rail; a pair of cylindrical guiding rails; means mounting said cylindrical guiding rails on said upright frame members, said means being adjustable for adjusting the position of said guiding rails, and the axes of said supporting and said guiding rails all being parallel to each other; a moveable machine element received between said supporting rail and said guiding rails; a supporting bearing means carried by said machine element and resting on said supporting rail, said supporting bearing means being in contact with the upper surface of said supporting rail for a substantial linear distance; first lubrication housing means enclosing said supporting bearing means and engaged with said supporting rail; two vertical guide bearing means carried on the upper portion of said moveable element, said vertical guide bearing means each being in contact with the underside of one of said guiding rails for a substantial linear distance; two horizontal guide bearing means mounted on the upper, opposite end portions of said moveable element, said horizontal guide bearing means each being in contact with the inner side of one of said confronting guiding rails for a substantial linear distance; second lubrication housing means enclosing said vertical and said horizontal guide bearing means and in engagement with said guiding rails; and means for supplying liquid lubricant to said first and said second lubrication housing means.

Claim 9

In a machine as recited in claim 6, wherein said means mounting said supporting rail comprises: a rectangular mounting bar on said horizontal supporting surface; a downwardly facing, L-shaped support bracket having a V-shaped groove on its upper surface for receiving said cylindrical supporting rail; means securing said supporting rail within said V-shaped groove; shim means for insertion as needed between the inner surfaces of said downwardly facing L-shaped support bracket and said mounting bar; and fastener means for securing said L-shaped support bracket to said mounting bar.

Claim 10

In a machine as recited in claim 7, wherein said means mounting said guiding rails comprises: an L-shaped guidE bracket for each of said guiding rails, arranged to be engaged over the upper edge of the associated on of said upright frame member, said L-shaped guide bracket having a V-shaped groove therein for receiving said cylindrical guiding rail; means securing said guiding rail within said V-shaped groove; shim means for insertion as needed between the inner surfaces of said L-shaped guide bracket and the upper edges of said upright frame member; and fastener means for securing said L-shaped guide bracket to said upright frame member.
