An automatic setting tool operatively coupled to a standard, rotary-impact drill-hammer for driving the shaped shank of a single piece anchor having an enlarged head into a hole drilled in masonry. The tool includes a rod having a front striker section and a rear holder section, a shoulder being formed at the junction of these sections. The holder section of the rod is adapted either to slip onto a drill bit held in the chuck of the drill-hammer or to be directly gripped by this chuck, whereby the rod, as it is rotated by the drill-hammer, is caused periodically to undergo a forward and a reverse stroke. Telescoped over the striker section and slidable thereon is a locator sleeve that is urged by a helical spring interposed between the shoulder and the sleeve to an initial position at which the sleeve projects beyond the front end of the rod to define therewith a socket for nesting the head of the anchor. In operation, when the shank of the anchor is placed in the entry of the drilled masonry hole and the head thereof which is nested in the socket is struck by the striker section during each forward stroke to drive the shank further into the hole, the spring is then compressed and the depth of the socket is reduced without, however, dislodging the head of the anchor therefrom. As a consequence, the alignment between the tool and the anchor is maintained in the course of the driving action.
RELATED APPLICATION:
This application is a continuation-in-part of my copending application Ser. No. 643,392, filed Aug. 23, 1984, entitled "Single Piece Pre-Shaped Wall Anchor," now U.S. Pat. No. 4,828,445.
A tool for driving and setting a nail-in anchor into concrete. The tool has a drive pin which can be locked and unlocked. When the drive pin is locked, the tool, used with a hammer, will drive only the anchor sleeve into a pre-drilled hole in concrete. When the drive pin is then unlocked, the tool, again used with a hammer, will nail the nail into the sleeve and set the anchor. The tool can be manipulated using only one hand. The tool typically has a thumb cap which, when rotated, locks and unlocks the drive pin. The tip of the tool is machined to have a concave shape for fitting over the convex-shaped dome of a typical nail-in anchor. The outer surfaces of the tool can have knurls to improve handling.
A tool for driving and setting nail-pin anchors and anchor bolts into concrete, the tool using the percussive action of a rotary hammer drill. The tool comprises a body member with a spring, a driver, and a ram inserted into the body member's bore. After a hole is drilled for insertion of the anchor, the masonry drill bit of the rotary hammer drill is slid inside the bore of the ram and temporarily locked to the tool. The rotary hammer drill is activated, and the drill bit turns inside the ram without affecting the body member or the anchor. Instead, the percussive force of the rotary hammer drill transfers its impact to the ram and the driver, which impacts the nail of the nail-pin anchor, or the stem of the anchor bolt, setting it into the concrete. A keyed bearing can be installed inside a sleeve of the ram in order to protect the tip of the masonry drill bit from shearing.
The present invention is directed to a tool assembly for improving the insertion of threaded studs into confined spaces. The tool assembly includes a shaft having a bearing surface and defining an opening that is spaced apart from the bearing surface. The tool assembly also includes a sleeve having a threaded inside surface portion and a non-threaded inside surface portion, the non-threaded inside surface portion defining an opening, the sleeve mounted to the shaft with the sleeve opening aligned with the shaft opening. The tool assembly further includes a stop member positioned in the shaft opening and sleeve opening.
An anchor setting device for setting a concrete anchor into concrete and leaving a desired length exposed. The anchor setting device includes a body having a bore extending through the body. The body has a first end and a second end. The bore of the body is threaded for releasably receiving a threaded end of a concrete anchor. The body has a slot extending through a side of the body facilitating insertion of the threaded end of the concrete anchor a desired length into the bore. The first end of the body is designed for being struck by an impact device for driving the concrete anchor into a hole in an anchoring surface when the first end of the body is struck by the impact device. The second end of said body is designed for abutting against the anchoring surface when the concrete anchor is driven into the hole.
A universal driving and setting tool is used to drive and set an anchor, such as a concrete anchor, having an anchor sleeve and an anchor slug positioned within a bore formed in the anchor sleeve. The driving and setting tool includes an attachment that fits over standard drill bits used in a hammer drill for drilling a hole in a substrate, such as concrete, in which the anchor is set. The attachment engages an end of the drill bit and can fit over drill bits having different lengths and having shanks of different shapes. The driving and setting tool also includes a reversible adapter that is positioned in the attachment in either a first or second position. In a first position, an anchor sleeve hammering portion on the reversible adapter faces outwardly to hammer the anchor sleeve into the hole within the substrate. In the second position, an anchor slug hammering portion extends outwardly to hammer the anchor slug within the anchor sleeve, thereby securing the anchor sleeve against the hole in the substrate and setting the anchor.
