Patent number: 5245900Abstract: A die press unloader which retrieves material from beneath the lower die of a pair of dies mounted in a die press. The material which is retrieved will have passed through the lower die, and can comprise either scrap, for example in making perforated strip or product, for example in making shaped blanks from a strip. The unloader utilizes a combination of gravity and a mechanical arm, preferably actuated by a double-acting air cylinder, the movements of which are controlled by the press itself.Type: GrantFiled: March 29, 1991Date of Patent: September 21, 1993Inventor: Siegfried Dojnik

Patent number: 5244193Abstract: A T-slot bolt sleeve for retaining the head of a conventional bolt in the T-slot of a machine tool table. The sleeve has a lower base block portion which slides in the main portion of the T-slot, and a neck portion which extends upwardly from this so as to ride in the relatively narrow entrance slot. There is a recess in the bottom of the base block for receiving the head of the bolt, and the shank of the bolt passes through a bore which extends upwardly from this. This holds the bolt in an inverted position so that the threaded end extends upwardly from the table for attachment of a nut or other fitting. The bottom of the base block is provided with a planar bearing surface which supports the assembly against side-to-side rocking as this is slid through the T-slot. The invention permits ordinary bolts of various lengths to be used in place of conventional T-nuts or T-bolts.Type: GrantFiled: August 7, 1992Date of Patent: September 14, 1993Inventor: Kenneth L. Hehr

Patent number: 5236110Abstract: A holding arrangement includes a pair of elongated branch members forming, for example, a support for a cycle rack, with a pair of links being arranged in a vicinity of lower ends of the branch members for connecting the branch members so as to enable a relative displacement between the branch members. An arrangement is disposed between the lower end portion and the upper end portion of the branch members for displacing the branch members from a closed position to an opened position and for applying a tensioning force to the branch member so as to lock the branch members to an object. The lower end of each branch member is provided with an arrangement for enabling a securing of the branch members to the object upon a displacement of the branch members to the opened position.Type: GrantFiled: October 11, 1991Date of Patent: August 17, 1993Assignee: Erik Schmidt Autotilbehor A/SInventor: Erik Schmidt

Patent number: 5236292Abstract: An apparatus for precisely locating a workpiece along a Y-axis of a milling machine worktable includes a fixture body having a generally rectangular cross section and at least one generally planar reference surface. The body has three longitudinally spaced apart apertures formed therethrough for retaining bolts. A nut threadably engages the center bolt and cooperates with an inverted T-shaped slot formed in the workpiece supporting surface of the worktable to clamp the body to the table. The body has a pair of spaced apart channels formed therein each with a longitudinal axis generally perpendicular to a longitudinal axis of the body, the channels being located at associated ones of the other two apertures. A foot having a pedestal portion is located in each channel for engaging a corresponding slot formed in the worktable. The feet are formed with a width corresponding to a width of an opening of the slot in which they are located.Type: GrantFiled: June 26, 1991Date of Patent: August 17, 1993Inventor: Donald S. Loucks, Jr.

Patent number: 5234205Abstract: A quick die change clamp secures a workpiece to a work surface equipped with a T-slot. The quick die change clamp includes a fastener having a threaded end and a head at an end opposite the threaded end for slidable movement in a T-slot of a work surface. The quick change clamp also includes a clamp bar adapted to engage and disengage a workpiece and a rotatable flange stem nut attached to the clamp bar for moving the clamp bar along the threaded end.Type: GrantFiled: January 15, 1992Date of Patent: August 10, 1993Inventor: Stephen F. Shanley

Patent number: 5206982Abstract: Structure for and method of die transfer. The structure comprises low friction bearing structures set into elongated T-slot bars secured in parallel, transverse spaced apart relation on a bolster plate and a die transfer truck table top actuable in response to the table top being raised to the level of the top of the T-slot bars with the table adjacent the bolster plate to raise a die positional on either the truck or bolster plate and facilitate universal movement of the die in a plane parallel to the top of the bolster plate. V-block and pin structure for centering the die on the bolster plate and die clamping structure including a washer having one straight edge and which moves axially of a bolt with a nut are also part of the die transfer structure.Type: GrantFiled: August 27, 1990Date of Patent: May 4, 1993Inventor: Donald H. Brown

Patent number: 5186228Abstract: A workbench including a work top which is supported by a base. The base includes a plurality of attachment points of which various implements such as clamps, brackets and other accesories are removably mountable such that they are secured to the workbench without requiring attachment to the work top, thereby enabling the work top to remain unmarred, imperforate and in good working condition. The plurality of attachment points allow the implements to be mounted to the base in various positions as desired.Type: GrantFiled: February 8, 1991Date of Patent: February 16, 1993Inventor: Donald C. Stafford

Patent number: 5139501Abstract: A device for folding an elastic rubber intraocular lens, has two lens gripping elements which can be moved one relative to the other and which can be brought into contact with a lens body from diametrically opposite positions on a block frame. A lens reception space is provided between the gripping elements with a base surface for the flat positioning of the lens body. The space is open from the top to permit the lens to be folded when the two lens gripping elements are brought together.Type: GrantFiled: February 26, 1991Date of Patent: August 18, 1992Inventor: Dieter Klaas
