Patent number: 5205457Abstract: A driving tool and method for injecting fasteners such as nails, or the like into workpieces such as drywall, ceilings or wood for framing a building. The driving tool includes a piston coupled to a rod that is driven forward to engage a head of a nail within a chamber of a barrel and drive the nail out the tool through a nozzle. The tool has a resilient member that is impacted on one end by a piston engaging with the nail to slow the piston's and rod's forward velocity. The resilient member is attached at its other end to a rigid member which is coupled to an indentor. The rigid member stops the forward velocity of the piston head and piston rod to limit the penetration of the nailhead into the drywall while placing an indention in the wall with an indentor. The nozzle is shaped to contact the shank of the fastener as the nail is driven through the tool's chamber to ensure that the nail is maintained perpendicular to the surface of the drywall as the nail exits the tool.Type: GrantFiled: January 6, 1992Date of Patent: April 27, 1993Inventor: Roy A. Blomquist, Jr.

Patent number: 4867366Abstract: A pneumatically operated fastener-driving tool, particularly adapted for nailing drywall to the framing of a building, comprising a housing, a reciprocator assembly mounted within the housing, and a piston mechanism mounted within the reciprocator assembly for axially driving the fastener into the drywall and underlying framing member. Upon actuation of the tool, the piston is pneumatically driven through a fastener-driving stroke and the reciprocator is reactively driven in an opposite direction. The oppositely driven reciprocator assembly absorbs recoil energy during the piston's driving stroke without transmitting an appreciable amount thereof to the housing, thereby substantially precluding housing recoil during driving of the fastener. At the end of the driving stroke, the reciprocator engages and is decelerated by the piston, thereby reducing housing recoil subsequent to the driving of the fastener.Type: GrantFiled: January 23, 1986Date of Patent: September 19, 1989Inventor: Edward O.

Patent number: 4187589Abstract: This disclosure relates to a fastener driving device which produces a slot around a shank of the fastener as it is being driven. It is useful in a situation where a sheet material which is subject to expansion and contraction is to be fastened to a base and wherein movement resulting from expansion and contraction must be permitted to avoid buckling. The invention resides specifically in the guide body and driver element of the tool in that the driver element is T-shaped in cross section with the central portion of the T constituting the driver proper and the portions extending laterally from the central portion terminating below the bottom of the driver proper and having a recess extending from the bottom of the driver proper through the length of said punch into which the shank of a fastener may be pushed. In this way as the fastener is driven into the base through the sheet material, a slot is formed extending to both sides of the shank of the fastener.Type: GrantFiled: February 27, 1978Date of Patent: February 12, 1980Inventor: William T. Jobe, II
