Abstract
Abstract A string changer cable for compound bows has a pair of tubular members of split-sleeve construction for engaging the tension cables of the compound bow as well as the bowstring holders. Each tubular member has an elongate slot providing tension cable access to an inner tapered passage which captively holds the tension cable during the string changing operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A bowstring changer for use with a compound bow of the type having the bowstring normally stretched between two oppositely biased tension cables and releasably coupled at opposite ends to the cables, said changer including: a pair of normally spaced, substantially tubular members each having a generally cylindrical passage and a generally axially extending slot formed in the wall of said member, each said slot being in communication with the passage for permitting selective placement of the tubular member around a respective tension cable, each of said members having a face at one end of their respective passages for abutting against a holder on respective ends of each tension cable when the changer is positioned to join the cables; and means for connecting and limiting the maximum spacing between said members to a predetermined distance, said last mentioned means, when connected to tension caables, permitting a strung bowstring to be removed from holders on the ends of the tension cables.
Claim 2
Dependent Claim
160 words
A bowstring changer for use with a compound bow of the type having the bowstring normally stretched between two oppositely biased tension cables and releasably coupled at opposite ends to the cables, said changer including: a pair of normally spaced, substantially tubular members each having a generally cylindrical passage and a generally axially extending slot formed in the wall of said member, each said slot being in communication with the passage for permitting selective placement of the tubular member around a respective tension cable, each of said members having a face at one end of their respective passages for abutting against a holder on respective ends of each tension cable when the changer is positioned to join the cables; and means for connecting and limiting the maximum spacing between said members to a predetermined distance, said last mentioned means, when connected to tension caables, permitting a strung bowstring to be removed from holders on the ends of the tension cables.
Claim 3
Dependent Claim
31 words
A device as claimed in claim 1, wherein said limiting means is secured to each of said members laterally of said cylindrical passage on one end of each of said members.
Claim 4
Dependent Claim
17 words
A device as claimed in claim 2, wherein said limiting means comprises a length of flexible cable.
Claim 5
Dependent Claim
30 words
A device as claimed in claim 3, wherein said flexible cable is mounted on each of said members obliquely relative to the respective longitudinal axes of each said cylindrical passages.
Claim 6
Dependent Claim
