Installation tool for setting anchors

A tool for setting an assembled anchor within an aperture of a substrate, the aperture having a depth which is at least as long as a length of the assembled anchor, said tool comprising:

• a shaft having a first end and a second end, said shaft being at least partially threaded proximate to said second end thereof;
• means for rotating said shaft;
• a body having a first end and a second end, said body having an aperture extending from said first end thereof to said second end thereof, said shaft being positioned within said aperture with said first end of said shaft being positioned within said aperture proximate to said first end of said body and with said second end of said shaft being positioned within said aperture and extending beyond said second end of said body such that the assembled anchor can be threadedly engaged with said shaft from said second end of said shaft;
• and
• a normally-expanded spring member positioned around said body proximate to said second end thereof.

A tool for setting an assembled anchor within an aperture of a substrate, the aperture having a depth which is at least as long as a length of the assembled anchor, said tool comprising:

• a shaft having a first end and a second end, said shaft being at least partially threaded proximate to said second end thereof, said shaft has a first portion, a second portion, a third portion and a fourth portion, said first portion being provided at said first end of said shaft, said second portion extending from said first portion toward said second end of said shaft, said third portion extending from said second portion toward said second end of said shaft, said third portion being externally threaded, said fourth portion extending from said third portion to said second end of said shaft;
• means for rotating said shaft;
• and
• a body having a first end and a second end, said body having an aperture extending from said first end thereof to said second end thereof, said shaft being positioned within said aperture with said first end of said shaft being positioned within said aperture proximate said first end of said body and with said second end of said shaft being positioned within said aperture and extending beyond said second end of said body such that the assembled anchor can be threadedly engaged with said shaft from said second end of said shaft, said aperture has a first portion, a second portion, and a third portion, said first portion of said aperture extending from said first end of said body toward said second end of said body, said second portion of said aperture extending from said first portion of said aperture toward said second end of said body, said second portion of said aperture having a diameter which is smaller than a diameter of said first portion of said aperture such that a shoulder is defined between said first and second portions of said aperture, said third portion of said aperture extending from said second portion of said aperture to said second end of said body, said third portion of said aperture having a diameter which is larger than said diameter of said second portion of said aperture such that a shoulder is defined between said second and third portions of said aperture, said third portion of said aperture defining a stop cavity.

A tool for setting an assembled anchor within an aperture of a substrate, the aperture having a depth which is at least as long as a length of the assembled anchor, said tool comprising:

• means for engaging the assembled anchor;
• means for rotating said engaging means such that the assembled anchor is drawn up said engaging means a required distance to set the assembled anchor within the aperture of the substrate;
• means for preventing the assembled anchor from being drawn up said engaging means beyond said required distance;
• and
• means for identifying when the assembled anchor is set within the aperture of the substrate, said identifying means comprises a normally-expanded spring member positioned around said preventing means, said spring member capable of being compressed such hat said spring member solids up, the assembled anchor being set when said spring member solids up.

A method of setting an assembled anchor in a substrate, said method comprising the steps of:

• forming an aperture within said substrate which is at least as long as said anchor;
• threading said assembled anchor onto a threaded shaft of said tool until said assembled anchor is against a tool face surface;
• inserting said tool into said aperture of said substrate such that a portion of said tool is positioned against a surface of said substrate;
• applying a pressure to said tool to prevent rotation of said tool on said surface of said substrate;
• and
• rotating said threaded shaft of said tool to draw said assembled anchor up said threaded shaft of said tool toward a body of said tool to set said assembled anchor within said aperture of said substrate, wherein during generally said entire rotation of said threaded shaft, said portion of said tool remains positioned against said surface of said substrate.

• forming an aperture within said substrate which is at least as long as said anchor;
• threading said assembled anchor onto a threaded shaft of said tool until said assembled anchor is against a tool face surface;
• inserting said tool into said aperture of said substrate such that a portion of said tool is positioned against a surface of said substrate;
• applying a pressure to said tool to prevent rotation of said tool on said surface of said substrate;
• rotating a spring along an outwardly threaded body of said tool until an end of said spring is flush with said tool face surface;
• tightening a jam nut against a spring retainer nut to lock said spring in position;
• and
• inserting said tool into said aperture of said substrate such that said spring is against a surface of said substrate, said spring being said portion of said tool which is positioned against said surface of said substrate.
