Abstract

Abstract This invention relates to an adjustable spanner wrench for rotating a cylindrical rod guide cap having a plurality of circumferentially spaced apart openings. The adjustable spanner wrench includes an elongated handle with a first and a second arm member attached thereto. The first arm member is rigidly attached to one end of the handle while the second arm member is adjustably attached at a distal point from the first arm member. Secured to each of the arm members is a tool with a hardened flat tip. These tools are held in an oppositely aligned and parallel relationship by the first and second arm members and are designed to engage two of the oppositely aligned openings in the rod guide cap. The adjustable spanner wrench further includes adjusting means associated with at least one of the arm members for urging the first and second arm members together so that the two tools positively engage two of the openings in the rod guide cap.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 235 words
An adjustable spanner wrench for rotating a hydraulic cylinder rod guide cap which has a plurality of circumferentially spaced apart and oppositely aligned openings, said wrench comprising: (a) an elongated handle containing a plurality of spaced apart openings; (b) a first arm member rigidly attached to one end of said handle and projecting outward therefrom; (c) a second arm member containing a plurality of spaced apart bolt holes adjustably positioned on said handle, distal from said first arm member, and projecting outwardly therefrom; (d) a first and a second tool secured to said first and second arm members, respectively, in an inline and parallel relationship, each of said tools containing a hardened tip capable of positively engaging one of said openings in said rod guide cap; (e) fastening means for attaching said second arm member to said handle, said fastening means including a bolt and nut, said bolt passing through one of said spaced apart openings in said handle and through one of said bolt holes in said second arm member such that said first and second tools are equal distance from said fastening means; and (f) adjusting means positioned between said second arm member and said handle for forcing said second arm member toward said first arm member so that said first and second tools positively engage two of said oppositely aligned openings in said rod guide cap and exert an equal force thereon.
Claim 2
Dependent Claim 235 words
An adjustable spanner wrench for rotating a hydraulic cylinder rod guide cap which has a plurality of circumferentially spaced apart and oppositely aligned openings, said wrench comprising: (a) an elongated handle containing a plurality of spaced apart openings; (b) a first arm member rigidly attached to one end of said handle and projecting outward therefrom; (c) a second arm member containing a plurality of spaced apart bolt holes adjustably positioned on said handle, distal from said first arm member, and projecting outwardly therefrom; (d) a first and a second tool secured to said first and second arm members, respectively, in an inline and parallel relationship, each of said tools containing a hardened tip capable of positively engaging one of said openings in said rod guide cap; (e) fastening means for attaching said second arm member to said handle, said fastening means including a bolt and nut, said bolt passing through one of said spaced apart openings in said handle and through one of said bolt holes in said second arm member such that said first and second tools are equal distance from said fastening means; and (f) adjusting means positioned between said second arm member and said handle for forcing said second arm member toward said first arm member so that said first and second tools positively engage two of said oppositely aligned openings in said rod guide cap and exert an equal force thereon.
Claim 3
Dependent Claim 33 words
The adjustable spanner wrench of claim 1 wherein said handle is angularly offset from the center line of said rod guide cap that when extended passes though the pivot point of said wrench.
Claim 4
Dependent Claim 223 words
An adjustable spanner wrench for rotating a hydraulic cylinder rod guide cap which has a plurality of circumferentially spaced apart and oppositely aligned openings, said wrench comprising: (a) an elongated handle containing a plurality of spaced apart openings; (b) a first arm member rigidly attached to an end of said handle and angularly projecting outward therefrom; (c) a second curve shaped arm member containing a plurality of spaced apart bolt holes, said second arm member adjustably positioned on said handle distal from said first arm member; (d) a first and a second tool secured to said first and second arm members, respectively, in an inline and parallel relationship, each of said tools containing a hardened tip capable of positively engaging said openings in said rod guide cap; (e) a fastener passing through one of said spaced apart openings in said handle and through one of said bolt holes in said second arm member for attaching said second arm member to said handle so that said first and second tools are arranged in oppositely aligned openings in said rod guide cap; and (f) a rotatable adjusting bolt situated between said handle and said second arm member for forcing said second arm member toward said first arm member to insure that said first and second tools positively engage said openings in said rod guide cap.
Claim 5
Dependent Claim 223 words
An adjustable spanner wrench for rotating a hydraulic cylinder rod guide cap which has a plurality of circumferentially spaced apart and oppositely aligned openings, said wrench comprising: (a) an elongated handle containing a plurality of spaced apart openings; (b) a first arm member rigidly attached to an end of said handle and angularly projecting outward therefrom; (c) a second curve shaped arm member containing a plurality of spaced apart bolt holes, said second arm member adjustably positioned on said handle distal from said first arm member; (d) a first and a second tool secured to said first and second arm members, respectively, in an inline and parallel relationship, each of said tools containing a hardened tip capable of positively engaging said openings in said rod guide cap; (e) a fastener passing through one of said spaced apart openings in said handle and through one of said bolt holes in said second arm member for attaching said second arm member to said handle so that said first and second tools are arranged in oppositely aligned openings in said rod guide cap; and (f) a rotatable adjusting bolt situated between said handle and said second arm member for forcing said second arm member toward said first arm member to insure that said first and second tools positively engage said openings in said rod guide cap.
