Abstract
Abstract A tool and process for the recovery of hollow-shafted target arrows which are in a backstop or target member from which the force necessary to remove the arrowhead is likely, if applied to the shaft, to cause distortion of the shaft. The hollow shaft is removed from the arrowhead and the arrowhead is positively engaged by an extractor which will remain intact under the application of the necessary withdrawal force. The arrowhead is withdrawn, disengaged from the extractor, and reaffixed to the arrowshaft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
An archery process which comprises discharging from a bow an arrow having a shaft and a head threaded thereto, embedding said head in a substrate from which the force which must be applied to said shaft to effect removal of said arrow may be sufficient to cause deformation of said shaft if applied thereto, unthreading said shaft from said embedded arrowhead, threadably engaging said arrowhead with a mating threaded end of a greater strength extractor tool having an outer diameter not greater than said shaft, extracting said arrowhead from said substrate by use of said extractor tool, recovering said arrowhead by unthreading said recovery arrowhead from said extractor tool threaded end, and rethreading said recovered arrowhead to said shaft.
Claim 2
Dependent Claim
119 words
An archery process which comprises discharging from a bow an arrow having a shaft and a head threaded thereto, embedding said head in a substrate from which the force which must be applied to said shaft to effect removal of said arrow may be sufficient to cause deformation of said shaft if applied thereto, unthreading said shaft from said embedded arrowhead, threadably engaging said arrowhead with a mating threaded end of a greater strength extractor tool having an outer diameter not greater than said shaft, extracting said arrowhead from said substrate by use of said extractor tool, recovering said arrowhead by unthreading said recovery arrowhead from said extractor tool threaded end, and rethreading said recovered arrowhead to said shaft.
Claim 3
Dependent Claim
19 words
An archery process as set forth in claim 1 in which said arrowhead is embedded in a wood substrate.
Claim 4
Dependent Claim
33 words
An archery process as set forth in claim 1 wherein recovery of the arrowhead necessitates applying a withdrawl force of at least three pounds in order to extract said arrowhead from said substrate.
Claim 5
Dependent Claim
22 words
An archery process as set forth in claim 1 wherein recovery of the arrowhead necessitates applying withdrawl and generally axial twisting forces.
Claim 6
Dependent Claim
117 words
An arrowhead extractor for use with archery arrows having relatively deformable and breakable arrowshafts and arrowheads which are embedded in an arrowhead-retaining substrate and from which an associated arrowshaft of an embedded arrowhead has been unthreaded and removed from thread means on a neck portion of said arrowhead, said extractor comprising a handle member, an elongated shank member projecting therefrom and having a diameter at least at a distal end thereof not greater than said arrowshaft, said extractor shank member being of substantially greater strength than that of said arrowshaft to facilitate the extraction, and thread means at the distal end of said extractor''s elongated shank member for mating engagement with complementary thread means of said arrowhead.
Claim 7
Dependent Claim
117 words
An arrowhead extractor for use with archery arrows having relatively deformable and breakable arrowshafts and arrowheads which are embedded in an arrowhead-retaining substrate and from which an associated arrowshaft of an embedded arrowhead has been unthreaded and removed from thread means on a neck portion of said arrowhead, said extractor comprising a handle member, an elongated shank member projecting therefrom and having a diameter at least at a distal end thereof not greater than said arrowshaft, said extractor shank member being of substantially greater strength than that of said arrowshaft to facilitate the extraction, and thread means at the distal end of said extractor''s elongated shank member for mating engagement with complementary thread means of said arrowhead.
Claim 8
Dependent Claim
25 words
An arrowhead extractor as set forth in claim 5 in which said extractor handle member is of greater diameter than its said elongated shank member.
Claim 9
Dependent Claim
18 words
An arrowhead extractor as set forth in claim 6 in which said extractor handle member is circumferentially ridged.
Claim 10
Dependent Claim
32 words
An arrowhead extractor as set forth in claim 5 in which said elongated shank member is of tubular form and is of the same outside diameter throughout its length as said arrowshaft.
