Abstract

A locking arrangement to store setting forces including a housing, one or more recesses in the housing, one or more jam members in operable communication with one or more of the recesses, and an incremental setting force holding configuration receivable at the housing and placable in operable communication with one or more of the one or more jam members. A backlash reduction arrangement including a housing, one or more recesses in the housing, one or more jam members in operable communication with one or more of the recesses, and an incremental holding configuration receivable at the housing and placable in operable communication with one or more of the one or more jam members. The one or more jam members positioned within the housing to assure that at least one of the jam members will engage the incremental holding configuration with substantially no backlash. A method for setting a downhole tool.

Claims

exact text as granted — not AI-modified
1 . A locking arrangement to store setting forces comprising:
 a housing;   one or more recesses in the housing;   one or more jam members in operable communication with one or more of the recesses;   an incremental setting force holding configuration receivable at the housing and placable in operable communication with one or more of the one or more jam members, the one or more jam members positioned within the housing to assure that at least one of the jam members will engage the incremental setting force holding configuration with substantially no backlash.   
   
   
       2 . The arrangement as claimed in  claim 1  wherein the one or more jam members are balls. 
   
   
       3 . The arrangement as claimed in  claim 1  wherein the one or more jam members are configured as a rod and an ogive. 
   
   
       4 . The arrangement as claimed in  claim 1  wherein the one or more recesses include a biasing member to urge the jam member out of the recess and into operable communication with the incremental setting force holding configuration. 
   
   
       5 . The arrangement as claimed in  claim 4  wherein the biasing member is a resilient member. 
   
   
       6 . The arrangement as claimed in  claim 4  wherein the biasing member is a spring. 
   
   
       7 . The arrangement as claimed in  claim 1  wherein the incremental setting force holding configuration is a threaded member. 
   
   
       8 . The arrangement as claimed in  claim 1  wherein the incremental setting force holding configuration is a ratcheting member. 
   
   
       9 . The arrangement as claimed in  claim 1  wherein the incremental setting force holding configuration includes a thread having a flank half angle on a flank opposing the direction of setting force of about 20 degrees or less, including negative angles. 
   
   
       10 . The arrangement as claimed in  claim 1  wherein the one or more jam members are arranged orthogonally about the housing. 
   
   
       11 . The arrangement as claimed in  claim 1  wherein the one or more jam members are arranged helically about the housing. 
   
   
       12 . The arrangement as claimed in  claim 11  wherein the one or more jam members arranged helically are offset from a common helix angle among them. 
   
   
       13 . The arrangement as claimed in  claim 12  wherein the offset is effected with one of the one or more jam members to one side of the common helix angle and the next jam member of he one or more jam members is offset to an opposite side of the common helix angle. 
   
   
       14 . The arrangement as claimed in  claim 1  wherein the one or more jam members are arranged in a regular pattern about the housing. 
   
   
       15 . The arrangement as claimed in  claim 1  wherein the one or more jam members are arranged in an irregular pattern about the housing. 
   
   
       16 . A backlash reduction arrangement comprising:
 a housing;   one or more recesses in the housing;   one or more jam members in operable communication with one or more of the recesses;   an incremental holding configuration receivable at the housing and placable in operable communication with one or more of the one or more jam members, the one or more jam members positioned within the housing to assure that at least one of the jam members will engage the incremental holding configuration with substantially no backlash.   
   
   
       17 . A method for setting a downhole tool comprising:
 urging an incremental setting force holding configuration to move relative to a housing with a setting force initiator, the housing having one or more jam members disposed thereat and in operable communication with the holding configuration;   engaging at least one of the one or more jam members with the holding configuration;   releasing the setting force initiator   maintaining the setting force on the downhole tool with the holding configuration engaged with the one or more jam members of the housing.   
   
   
       18 . The method as claimed in  claim 17  wherein the engaging is by gravity. 
   
   
       19 . The method as claimed in  claim 17  wherein the engaging is by biasing member. 
   
   
       20 . The method as claimed in  claim 17  wherein the maintaining is without backlash.
