20120291980 | METHOD OF MANUFACTURING INTERLOCK FEATURE BETWEEN RAILCAR COUPLER CORES - A system for creating an interlock feature between two related railcar coupler cores comprises a first half of a corebox defining cavity for forming a first half of a railcar coupler core, a second half of a corebox defining a cavity for forming second half of a railcar coupler core, and a loose piece loose piece including an extension on a first side shaped to fit in the cavities. | 11-22-2012 |
20120291981 | INTERLOCK FEATURE FOR RAILCAR CORES - An interlock feature for railcar core comprises a lug on a first core, a slot on a second core, a first positive stop surface, and a second positive stop surface. | 11-22-2012 |
20120292280 | RAILCAR COUPLER KNUCKLE CORES WITH REAR CORE SUPPORT - A core assembly for creating interior spaces in a railcar coupler knuckle is designed to be set in a cavity with cope and drag sections. The cavity is shaped to form a railcar coupler knuckle and includes a first wall that forms the substantially vertical outside wall of the tail of the knuckle. The core includes a kidney section with a rear core support section that extends at least 0.5″ outside the first wall of the cavity when the core is set in the drag. | 11-22-2012 |
20120292281 | RAILCAR COUPLER CORE WITH VERTICAL PARTING LINE AND METHOD OF MANUFACTURE - A method of casting a core includes the steps of preparing a first half of a corebox, preparing a second half of a corebox such that the parting line of a core formed from the first and second coreboxes runs along the vertical axis of the core. | 11-22-2012 |
20120292282 | RAILCAR COUPLER KNUCKLE CORES AND KNUCKLES PRODUCED BY SAID CORES - A core assembly for forming the interior spaces of a railcar coupler knuckle has a first transition section between the C-10 portion of the core and the finger portion of the core. The first transition section has a first side, a second side, a third side and a fourth side and the first and second sides form the vertical axis of the first transition section and the third and fourth sides form the horizontal axis of said first transition section. The vertical axis of the first transition section has a height along a horizontal plane of the vertical axis of at least 2.5″ and the horizontal axis of said first transition section has a width along a vertical plane of the horizontal axis of at least 0.925″. | 11-22-2012 |
20130025811 | RIGGING SYSTEM FOR CASTING RAILCAR COUPLER PARTS - A rigging system for casting railcar coupler knuckles is provided. The rigging system comprises cope and drag portions of a mold, a down sprue defined in said cope portion, at least one riser defined in said mold, at least two ingates defined at least partially in said mold and connected to said at least one riser, at least two knuckle mold cavities defined in said mold, and wherein said ingates have a non-circular shape. | 01-31-2013 |
20130025815 | DOWN SPRUE CORE FOR USE IN CASTING RAILCAR COUPLER KNUCKLES - A core for use in railcar coupler part casting processes is provided. The core has a hollow body, a top with a first opening defined therein, a bottom having a generally rounded wall, and second and third openings defined in the side wall of the body. | 01-31-2013 |
20140034804 | DOWN SPRUE CORE FOR USE IN CASTING RAILCAR COUPLER KNUCKLES - A core for use in railcar coupler part casting processes is provided. The core includes a body with a side wall, a first opening in a top wall of said body a second opening in a bottom wall of said body, a channel defined through said body connecting said first and said second openings, and at least one channel defined in said bottom wall. | 02-06-2014 |
20140209554 | RAILCAR COUPLER KNUCKLE CORES AND KNUCKLES PRODUCED BY SAID CORES - A knuckle may include a throat portion having a throat side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. The throat portion may also include a tail stop side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. | 07-31-2014 |
20140319092 | RAILCAR COUPLER CORE WITH VERTICAL PARTING LINE AND METHOD OF MANUFACTURE - A method of casting a core includes the steps of preparing a first half of a corebox, preparing a second half of a corebox such that the parting line of a core formed from the first and second coreboxes runs along the vertical axis of the core. | 10-30-2014 |
