| 20110042936 | SWIVEL ASSEMBLIES FOR LOADING ARMS AND LOADING ARMS COMPRISING THE SAME - A swivel assembly includes a lower flange assembly having lower body portion, a first rim portion extending around the lower body portion, and a first fluid passageway. An upper flange assembly includes an upper body portion, a second rim portion extending around the upper body portion, and a second fluid passageway. A mating collar is positioned around the upper body portion and secured to the first rim portion such that the second rim portion is rotatably positioned between the mating collar and the first rim portion and the first fluid passageway is fluidly coupled to the second fluid passageway. Bearing elements are disposed between the first rim portion and the second rim portion and between the second rim portion and the mating collar such that the upper flange assembly and a combination of the lower flange assembly with the mating collar are rotatable with respect to each other. | 02-24-2011 |
| 20110012346 | COUPLER DEVICES WITH SPRING-LOADED COUPLER SLEEVES - A bottom loading coupler includes a coupler body and a plurality of interlocks. Each interlock is positioned in a slot in the body sidewall and pivotally coupled to the coupler body such that each interlock has an engaged position and a disengaged position with each interlock biased to the disengaged position. A coupler sleeve is slidably positioned around the coupler body and comprises a first, retracted position relative to the coupler body and a second, extended position relative to the coupler body. A biasing element is positioned between the coupler sleeve and the coupler body and biases the coupler sleeve to the second, extended position relative to the coupler body. The interlocks are in the disengaged position when the coupler sleeve is in the first, retracted position and in the engaged position when the coupler sleeve is in the second, extended position. | 01-20-2011 |
| 20110012345 | PIVOT RINGS FOR COUPLER DEVICES AND COUPLER DEVICES COMPRISING THE SAME - Coupler bodies with pivot rings for use in bottom loading couplers and bottom loading couplers comprising the same are disclosed. The coupler body for a bottom loading coupler may include a body sidewall having a fluid channel extending between an adapter end and a supply end. A plurality of slots may extend through the body sidewall of the coupler body. A pivot ring may extend substantially around the outer circumference of the coupler body. A plurality of interlocks may be positioned in corresponding slots in the body sidewall and pivotally engaged with the pivot ring. The interlocks are pivotable about the pivot ring between an engaged position and a disengaged position. | 01-20-2011 |
| 20110012344 | WEAR RINGS FOR COUPLER DEVICES AND COUPLER DEVICES COMPRISING THE SAME - A bottom loading coupler may include a coupler body and a plurality of interlocks. Each interlock may be positioned in a corresponding slot in the body sidewall and have an engaged position and a disengaged position with respect to the coupler body. A coupler sleeve formed from a first material may be slidably positioned around the body sidewall of the coupler body. A wear ring formed from a second material may be disposed on the inner circumference of the coupler sleeve. The wear ring and the coupler sleeve may form an interlock retaining seat. The coupler sleeve may have a first, retracted position relative to the coupler body, wherein the interlocks are biased to the disengaged position and retained in the interlock retaining seat. The coupler sleeve may also have a second, extended position relative to the coupler body, wherein the wear ring biases the interlocks to the engaged position. | 01-20-2011 |
| 20110011475 | Recock Handle Assemblies For Coupler Devices And Coupler Devices Comprising The Same - Recock handle assemblies for bottom loading couplers and bottom loading couplers comprising the same are disclosed. The recock handle assemblies for bottom loading couplers may include a lever portion comprising a first lever arm, a second lever arm and a lever bar oriented in a substantially u-shaped configuration. A handle portion may be joined to the lever portion with a first pivot block and a second pivot block, the handle portion comprising a first connecting leg, a second connecting leg, and a bail. The first connecting leg and the second connecting leg may be positioned in a first plane and the bail is non-coplanar with the first plane. A first base plate may be pivotally coupled to the first pivot block. The first base plate may include a first body guide member and a first sleeve guide member. A second base plate may be pivotally coupled to the second pivot block, the second base plate comprising a second body guide member and a second sleeve guide member. | 01-20-2011 |
| 20100096579 | HANDLE SHAFT ASSEMBLIES FOR BOTTOM LOADING COUPLERS - A handle shaft assembly includes a tube spacer, a handle shaft, a stuff box, and an operational handle. The stuff box may be configured for insertion into a through-hole within a bottom loading coupler body and include first and second stuff box ends defining a cylindrical cavity. A first sealing member may be positioned on the first stuff box end, and a second sealing member positioned on the second stuff box end. The tube spacer may be configured to be positioned within a blind counterbore of the bottom loading coupler body. The handle shaft may include a first end positioned within the tube spacer configured to be positioned with a blind bore of the bottom loading coupler body, a linkage section configured to be coupled to a drive linkage of a poppet valve assembly, and a second end extending through the cylindrical cavity of the stuff box. The operational handle is mechanically coupled to the second end of the handle shaft. | 04-22-2010 |
