Abstract
A runner apparatus is disclosed herein that is used alone or in combination with or incorporated into an existing torque wrench. The runner apparatus has a motor positioned offset from end operatively engaging a threaded member so that the runner apparatus or runner apparatus-torque wrench combination has a profile height that allows it to be positioned in confined spaces that are relatively small.
Claims25
A wrench assembly for loosening or tightening a threaded member in a confined space, comprising:
- (a) a first non-manual wrench configured to engage and rotate a threaded member;
- and
- (b) a second wrench comprising:
- (i) a motor;
- (ii) a runner driver configured to engage said threaded member, said runner driver operatively connected to said motor, whereby said runner driver and said threaded member may be rotated independently of said first wrench;
- and
- (iii) a housing extending substantially horizontally between said motor and said runner driver,
- wherein said confined space has a vertical dimension that is less than the sum of the vertical dimension of said motor, said runner driver, and said housing, but greater than the sum of the vertical dimensions of said first wrench and said housing.
A method of loosening a threaded member in a confined space comprising the steps of:
- (a) providing a first non-manual wrench comprising at least a drive head operatively engageable with a threaded member;
- (b) providing a second wrench operatively engageable with said drive head, said second wrench comprising:
- (i) a motor;
- (ii) a runner driver operatively engageable with said threaded member, said runner driver operatively connected to said motor, whereby said motor may rotate said threaded member;
- and
- (iii) a housing extending substantially horizontally between said motor and said runner driver, wherein said confined space has a vertical dimension that is less than the sum of the vertical dimension of said first wrench and said second wrench but greater than the vertical dimension of said drive head and said runner driver;
- (c) operating said first wrench;
- and,
- (d) operating said second wrench.
A method of tightening a threaded member in a confined space comprising the steps of:
- (a) providing a first non-manual wrench comprising at least a drive head operatively engageable with a threaded member;
- (b) providing a second wrench operatively engageable with said drive head, said second wrench comprising:
- (i) a motor;
- (ii) a runner driver operatively engageable with said threaded member, said runner driver operatively connected to said motor, whereby said motor may rotate said threaded member;
- and
- (iii) a housing extending substantially horizontally between said motor and said runner driver, wherein said confined space has a vertical dimension that is less than the sum of the vertical dimension of said first wrench and said second wrench but greater than the vertical dimension of said drive head and said runner driver;
- (c) operating said second wrench;
- and,
- (d) operating said first wrench.
A wrench assembly for loosening or tightening a threaded member in a confined space, comprising:
- (a) a first wrench configured to engage and automatically rotate a threaded member;
- and
- (b) a second wrench comprising:
- (i) a motor;
- (ii) a runner driver configured to engage said threaded member, said runner driver operatively connected to said motor, whereby said runner driver and said threaded member may be rotated independently of said first wrench;
- and
- (iii) a housing extending substantially horizontally between said motor and said runner driver,
- wherein said confined space has a vertical dimension that is less than the sum of the vertical dimension of said motor, said runner driver, and said housing, but greater than the sun of the vertical dimensions of said first wrench and said housing.
