Patent application numberDescriptionPublished
20090051073Combination Thermoforming Trim Press and Comminuting Apparatus - A combination thermoforming trim press and comminuting apparatus is provided. The combination includes a horizontal trim press, a comminuting apparatus, and a height-adjustable delivery chute. The trim press has an exit for downwardly delivering a scrap web of thermoformable sheet material. The comminuting apparatus is provided beneath the exit and has an entrance for receiving the scrap web. The height-adjustable delivery chute is provided between the trim press exit and the comminuting apparatus entrance and includes a first section, a second section telescopically received relative to the first section to provide height adjustment, and a fastener for securing the chute at a selected height to substantially close any gaps between the trim press exit, the comminuting apparatus entrance and the delivery chute to eliminate any need for a shielding cage to prevent internal finger and limb access by an operator.02-26-2009
20090071297Chainsaw Sharpening Tool - A file guide is provided having a tubular handle, a spindle, and a retainer. The tubular handle has a central bore with an inner bearing surface and an outer gripping surface. The spindle has a cylindrical outer bearing surface configured to mate in complementary, rotatable relation with the inner bearing surface of the handle, a head at a proximal end, a lock portion at a distal end, and a central receptacle configured to receive a file shank. The retainer has an inner surface with a complementary lock portion configured to interlock with the lock portion of the spindle03-19-2009
20090104013Apparatus for Orienting Stacks of Trimmed Molded Articles and Method - A thermoformed article stack guiding apparatus is provided with a frame, a guide ramp and an array of juxtaposed article guide channels. The guide ramp receives and guides individual stacks of inter-nested articles exiting a female die of a thermoforming trim press from multiple rows and multiple levels. A first set of article guide channels is inter-nested with a second set of article guide channels in an alternating array. Each of the first set and the second set is spread out laterally in a direction from an entrance end of the guide ramp to an exit end of the guide ramp to accept respective stacks of inter-nested articles from an upper row and a lower row of a trim press and transfer the stacks into a common exit row. A method is also provided.04-23-2009
20090113780SHOTGUN SIGHT AND ADJUSTABLE GUN SIGHT - A shotgun sight is provided with a barrel, a sighting rib, a rib support member, a pitch adjustment mechanism, and a latch mechanism. The rib support member is provided on the barrel. The pitch adjustment mechanism is provided between the rib and the rib support member to adjust pitch of the rib relative to the barrel. The latch mechanism has a pair of coacting base plates. A first base plate is provided along a proximal end of the rib and a second base plate is provided on the rib support member. Each base plate has an array of complementary-shaped interlocking projections. One of the base plates is configured to be forcibly urged apart from the other base plate to reposition the array of interlocking projections in order to selectively position the rib relative to the barrel at one of a plurality of locations each corresponding with a unique pitch for the rib relative to the barrel. An adjustable gun sight is also provided.05-07-2009
20100104413Thermoformed Article Stack Segmenting Apparatus - A thermoformed article stack segmenting apparatus is provided. The apparatus includes a frame, a stacked article guide channel, a forward engaging drive finger, a reciprocating actuator and a rearward engaging holding finger. The stacked article guide channel is carried by the frame and configured to receive and guide a stack of inter-nested articles exiting a female die of a thermoforming trim press. The reciprocating actuator is coupled with the finger to drive the finger forward in engagement with one separated stack of articles. The actuator also drives the finger rearward in a retractable state to separate another, successive stack of articles. The rearward engaging holding finger is supported by the frame and is configured to hold the another, successive stack while driving the forward engaging drive finger forward.04-29-2010
20100319431Rim Rolling Screw Having Pneumatic Cooling - A rim rolling apparatus is provided having a plurality of rim rolling screws, a motor and a pneumatic cooling circuit. Each screw has a hot section and a cool section provided downstream of the hot section. The motor is configured to drive the screws in rotation to feed thermoformed articles between the screws to roll lips of the articles. The pneumatic cooling circuit extends within the screw from an exit end towards an entrance end. The cooling circuit is provided in thermally conductive relation with the cool section and insulated from the hot section.12-23-2010
20100319837Thermoformable Web Splicer and Method - An apparatus and method are provided for splicing together old and new thermoformable sheets in order to supply a continuous thermoforming operation. The method for joining together thermoformable sheets includes: providing a first thermoformable sheet with a trailing edge and a second thermoformable sheet with a leading edge; forming a terminal edge portion with a hot element along the trailing edge and a complementary terminal edge portion along the leading edge by severing a scrap sheet from each portion; laterally retracting each scrap portion away from the trailing edge and the leading edge; and joining together the first thermoformable sheet and the second thermoformable sheet by interlocking together the terminal edge portion with the complementary terminal edge portion.12-23-2010
20110079123Apparatus and Method for Severing and Loading Bag Fasteners - A clip-separating machine is provided with a guide frame, a clipper, and a displacement structure. The guide frame is configured to support a strip of clips. The clipper has a pair of opposed cutting edges. One of the edges is supported for movement toward and away from another of the edges. The displacement structure is configured to move the one cutting edge toward the other cutting edge so as to cause co-action of the cutting edges to sever a terminal clip from a strip of clips. A method is also provided.04-07-2011
