System for setting grading stakes

Abstract

A system comprising components which facilitate a one-man stake ribbon setting process for grading a plot of land. The components include primarily a pair of rule holders which precisely position a rule immediately in front of a reference stake which has already had a ribbon set to accurately indicate exact grade. The rule holders, which cooperate with that reference stake, position the rule directly behind and in line with the grade locating nail and where it can be readily used to set the precise position of the ribbon requiring a second worker to hold the rule. An additional optional component of the invention comprises a sighting scope rule guide which is advantageously employed at the next stake to further enhance the accuracy of ribbon setting. This guide attaches to the sighting scope using a scope adapter and has a rule guide with an attached pointer showing the single worker the precise rule measurement on the rule when his scope is precisely level in viewing the ribbon on the remote reference stake.

1 . A system for use in setting ribbons on grading stakes on a plot of land to be graded, each such grading stake designating the desired height of the grade at an adjacent location identified by a location pointer such as a nail head; 
 the system comprising:    a lower rule holder releasibly affixed to a grading stake adjacent said pointer;    an upper rule holder releasibly affixed to said grading stake adjacent an upper end of said grading stake;    each of said lower and upper rule holders having a rule retainer for receiving a measuring rule in alignment with said grading stake and said pointer;    whereby one man can set a ribbon on said grading stake using said rule which is supported by said lower and upper holders.    
   
   
       2 . A system for holding a measuring rule against a grading stake to enable precise positioning of a grading ribbon on the stake by one worker; the system comprising: 
 at least one holder having a first channel for receiving said stake and a second channel for receiving said measuring rule.    
   
   
       3 . The system recited in  claim 2  comprising at least two said holders, one of said holders being configured for attachment to said stake closer to a selected first end of said stake and another of said holders being configured for attachment to said stake closer to a selected second end of said stake.  
   
   
       4 . The system recited in  claim 2  further comprising a sighting scope having a level for viewing a ribbon on a remote first grading stake; and 
 an adapter attachably affixed to said scope and having a guide for slideable engagement with a rule at an adjacent second grading stake for indicating on said rule a position corresponding to said viewed ribbon on said remote first grading stake.    
   
   
       5 . A system for use in setting ribbons on grading stakes on a plot of land to be graded; the system comprising: 
 a sighting scope having a level for viewing a ribbon on a remote first grading stake; and    an adapter attachably affixed to said scope and having a guide for slideable engagement with a rule at an adjacent second grading stake for indicating on said rule a position corresponding to said viewed ribbon on said remote first grading stake.    
   
   
       6 . The system recited in  claim 5  wherein said guide comprises a pointer for precisely pointing to a location on said rule and wherein said pointer is aligned with said sighting scope.
