  • Publication number: 20040164122
    Abstract: A nail setting tool has a body with an internal drive shaft and rubber end caps. A nail may be placed in the driving end of the body, and the nail is held in place by the gripping action of the rubber end cap. The internal drive shaft is held in place inside the body with a post and slot arrangement. A user may thus align, drive and counter sink a nail into a workpiece in one operation, without marring the workpiece or losing the nail. The nail setting tool also eliminates pinch points for added safety.

    Abstract: 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.

  • Patent number: 6155472
    Abstract: The nailing tool has a hollow main body including a valve slidable therein. The main body includes a compressed air reservoir, the compressed air keeping the valve closed in a resting position. An anvil is provided at the upper end of the tool, with an empty annular chamber at atmospheric pressure being located under the anvil and over a ring integrally attached to the valve. Thus, if a hammer blow is dealt on the anvil, the latter loosely slides inside the main body, without reaching the ring, with the valve remaining closed and no fastener being expelled from the tool. Upon a trigger being activated on the tool handle, compressed air fills the annular chamber between the anvil and the ring. In this condition, upon a hammer blow being dealt on the anvil, the impact of the blow is transmitted by the compressed air to the underlying ring, consequently opening the valve.

  • Patent number: 6123245
    Abstract: The nailer has a horizontal nail magazine and an integral vertical column. The magazine horizontally feeds the nails through an inclined inlet port, into a vertical channel located in the column, and inside which is vertically slidable a selectively powered driver rod which hits and expels the nails through a nail outlet port. The vertical channel has a front and a rear wall adjacent the single nail located in the channel, and lateral walls. The inclined inlet port is located in the channel rear wall. When the driver rod is forcibly downwardly driven along the channel, it hits the upper inclined nail head with its flat lower abutment edge, thus gradually pivoting the nail into a vertical position as the nail is being driven towards the nailer outlet port. This results in the nail being pivoted from a position in which it is in transverse register with the inlet port, to a position in which it is in transverse register with the channel rear wall.

  • Patent number: 6012623
    Abstract: A hammer-type stapler in which the staple driving element and the staple drive track defining structure are constructed and arranged with respect to the frame structure to move through a drive stroke incident to an operator grasping a handle portion and manually impacting the staple drive track defining structure on a workpiece. The direction of guided movement of a staple stick along the staple feed track is at an angle greater than 90.degree. with respect to the direction of the drive stroke of the staple driving element within the staple drive track, the arrangement being such that the leading staple will be driven into the workpiece in the direction of the drive stroke enabling the hand grip portion to be positioned for manual gripping so that the knuckles are spaced from a flat workpiece surface in which a staple has been driven generally perpendicularly therein.

  • Patent number: 5988296
    Abstract: A portable hand tool is provided for inserting a marker flag into the ground. The tool has a shaft (12) having a handle (30) attached at a first end, and a ground penetrating tip (14) extending from a second end. The ground penetrating tip has an aperture which extends longitudinally through shaft (12) and is adapted for receiving the stem portion of a marker flag. In operation, a portion (42) of the end of the flag stem is inserted in aperture (16). The flag stem is then bent back toward the tool shaft forming a U-shaped bend (44) in the flag stem. Following insertion into the ground, the bend acts as a barb to anchor the flag stem in the ground.

  • Patent number: 5875950
    Abstract: A nail driving apparatus including a handle having a first and second end and a rod member having a first end permanently secured to a second end of the handle and a second end forming a striking surface, where the handle and the rod member are secured together so as to form a longitudinal axis. The apparatus further includes an elongated guide tube having a first end and a second end, where the rod member is slidably disposed within the guide tube. The handle further includes a tapered annular ring located about the rod member. The annular ring is operative for receiving the first end of the guide tube within the handle, and for temporarily securing the guide tube to the handle.

  • Patent number: 5875951
    Abstract: A drive ring driver for driving drive rings into a desired surface is comprised of a rod that is slidably passed through a handle member. A shaft member is attached and secured to the second end of the rod via a rod adaptor. A drive ring head is secured to the shaft and is adapted to receive the head portion of a drive ring. Once the drive ring is received within the drive ring head, a force is imparted onto the first end of the rod and is transferred to the drive ring, thereby driving the drive ring into its intended surface.

  • Patent number: 5848463
    Abstract: A method and tool (15) for securing V-shaped, open connector elements (14) o belt ends (1) in a manual operation use staples (8) that are driven by hammer blows applied to a punch held by the tool. Each connector element (14) has at least two shanks (11, 12) and at least one eye loop (13) interconnecting the shanks. The staples (8) are initially held in place for the driving by one shank (11) of the connector elements (14). The securing elements (8) first penetrate holes in one shank (11), then the belt end (1), and then holes in the shank (12), whereupon the free end pieces (53, 54) of the staples (8) are bent over in the tool provided with a die (29) for this purpose. The connecting elements (14) have downwardly projecting shanks (12) which extend initially away from the belt end. These shanks (12) are first pressed against the belt end (1) with a manually produced force increased with the aid of a tool mechanism providing a mechanical advantage.

  • Patent number: 5779128
    Abstract: A nail driving apparatus comprising a tube, a rod with a mass attached to one end, a spring connecting the mass to the tube, and a sleeve encircling the exposed portion of rod between the tube and the mass. When the mass is in the forward, closed position, the spring is slightly stretched, holding the apparatus in the closed position. When the mass is drawn away from the tube, the spring is displaced, increasing the tension in the spring and, thus, aiding the user in driving a nail. An expandable sleeve protects the exposed portion of rod between the tube and the mass from being contaminated by debris. It also prevents the user's hand from being positioned at the point of contact. As the mass is drawn away from the tube, the sleeve expands to protect the entire length of exposed rod.
