Patent number: 10239274Abstract: A pneumatic die transfer system for a press machine comprises at least two primary roller rails and at least two secondary roller rails set in respective T-slots in a bolster. The primary roller rails are perpendicular to the secondary roller rails. Airbags below each roller rail are selectively inflated to elevate either the primary or the secondary roller rails above the bolster face. The secondary roller rails each have a plurality of discontinuities configured to receive the primary roller rails and their associated airbags in an intersecting fashion. As a result, the bolster can be easily fabricated with intersecting T-slots and relatively few roller rails are needed to achieve fully orthogonal conveyance of a heavy die over the face of a bolster.Type: GrantFiled: August 4, 2015Date of Patent: March 26, 2019Assignee: Wardcraft Conveyor, a Division of McLaughlin Ward & Co.Inventors: Patrick Sprague, James M.

Patent number: 6349638Abstract: A briquetting machine for compacting metal chips into briquettes with a movable die that provides plural die cavities. After metal chips are loaded into a loading chamber from a hopper, a chip compacting ram pushes the chips at a high speed and low pressure into one of several bores, disposed within a sliding die gate, and against an endplate. The bore and endplate together constitute a die and define at least two die cavities. After the ram reaches a predetermined low pressure, the ram then proceeds at a relatively low speed and relatively high pressure to compress the chips within the die into a briquette. Upon reaching a predetermined compaction pressure, the ram retracts from the bore. After such time, the die gate is moved to a location where one bore lies before an ejector cylinder. The ejector cylinder then extends into the bore, expelling the briquette from the bore.Type: GrantFiled: September 14, 1999Date of Patent: February 26, 2002Assignee: Prab, Inc.Inventor: Edward A.

Patent number: 4068577Abstract: A work supporting table has a carriage which extends beneath the bed of a press and a table top which extends over the bed. The carriage has wheels which rotate about eccentric spindles on the ends of the two axle shafts. Chains are wrapped around these shafts and forces are applied to the chains by an air cylinder mounted on the carriage. When the chains are drawn taut, the axles rotate such that the spindles move downwardly and cause the wheels to descend with respect to the carriage frame and thereby lift the table upwardly. The wheels when so disposed support the table with its table top slightly above the press bed. Conversely when the chains are released, the wheels move upwardly and the table top descends onto the press bed which supports it so that a force applied to a workpiece on the table top is resisted by the press bed.Type: GrantFiled: March 15, 1976Date of Patent: January 17, 1978Inventor: Patrick Joseph Murphy

The diaper stack is confined against shifting during carriage movement by two vertical bin walls and two fixed panels which partially enclose the open sides of the bins as the carriage is moved between the panels to the unloading position. When the bin is in the unloading position the stack is compressed by a vertical ram having a compression plate which enters the open top of the receptacle. After the stack is compressed a pusher plate moves horizontally into one open side of the bin and out the other open side to push the compressed stack through a funnel and into a shipping carton held on the funnel.Type: GrantFiled: October 27, 1976Date of Patent: November 8, 1977Assignee: Curt G.
