LEAD ANCHOR-SE'I'IIN G TOOL BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a setting tool for lead or other expandable metallic anchors. Lead anchors are conventionally used to provide supporting means in a wall for bolts, hooks, and the like, where access cannot be gained to the interior of the wall to mount a conventional nut and bolt type anchor.
2. The Prior Art A lead anchor is mounted by placing it in a close fitting orifice in a wall, then expanding the anchor against the walls of the orifice to achieve a tight, secure fit. In the past, when lead anchors were installed in walls, the anchors would sometimes fall in the stud spaces behind the walls because there has been no good way to hold the anchors securely while installing them in the walls. Once an anchor fell into the stud space there was no economical way to get it out. The only way to get it out was to cut a hole in the bottom of the wall. The cost of repairing the hole was more than the cost of the lead anchor.
It is an object of this invention to provide a setting tool for inserting lead anchors in walls.
It is a further object of this invention to provide a setting tool for inserting lead anchors in walls which enables an anchor to be held securely while it is being put in place.
Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views, in which:
FIG. 1 is an exploded perspective view of the tool of the invention;
FIG. 2 is a side elevational view of the tool of the invention, showing it in operative position; and
FIG. 3 is a front elevational view of the tool of the invention, showing the operative wrenches in position.
DESCRIPTION OF THE PREFERRED EMBODIMENT The body also has an annular groove around the end adjacent the nose l4 and a small bore 22 extending from the bed of the groove 20 to the central bore 16, having an axis transverse to the axis of the central bore 16.
A drive bolt 24 having a threaded end 26, an enlarged diameter section 28 having an annular groove 30 in it, and a still further enlarged diameter head 32 with a hexagonal shaped'internal recess 34 for receiving a wrench head, is seated in the central bore 16 of the body 12. The groove 30 in the enlarged diameter section 28 is positioned so that when the drive bolt 24 is in place within the body 12, it is in concentric radial alignment with the groove 20in the body 12. When the drive bolt 24 is seated within the main body 12, a pin 36 is inserted in the small bore 22, engaging the groove 30 in the enlarged diameter section '28. A retaining split ring 38 is then seated in the groove 20, holding the pin 36 in place, thus retaining the bolt 24 against axial movement.
In use, an anchor 40 (not a part of the invention) compris' ing a tubular outer member 42 and a conically shaped inner member 44 having a threaded central bore 46, is threaded onto the threaded end 26 of the bolt 24 seated in the body 12. The base of the conical shaped inner member 44 is greater in diameter than the interior diameter of the outer member 42. The anchor 40 is then placed in position in an orifice 48 in a wall 50. A wrench 52 is then placed around the main body 12 and an Allen wrench 54 is inserted in the recess 34 of the bolt 24. The split ring 38 serves as a support for the wrench 52. The bolt 24 is then rotated while the body 12 is held steady. Rotating the bolt 24 draws the inner member 44 of the lead anchor 40 toward the tool 10 while the conical nose 14 of the body 12 is drawn toward the outer member 42. Drawing the inner member 44 of the anchor 40 toward the bolt 24, causes the outer member 42 to expand at both ends, seating the anchor 40 tightly within the wall 50. The expansion at the rearward end of the anchor 40 is due to the pressure of the inner member 44 on the outer member 42 while the expansion at the forward end is due to the pressure of the conical nose 12.
It should be appreciated that m size of the tool 10 as well as the size of the bolt 24 can be varied to enable practically any size lead anchor to be installed. The dimensions of the parts need only be such that the bolt 24 can be seated in the main body 10, and that the threaded end 26 of the bolt fit the inner member 44 of the anchor 40.
