Patent number: 4204625Abstract: An apparatus for installing a tack strip or the like providing a rigid frame having an adjustable guide which spaces the tack strip at a proper distance from a wall, baseboard, or other guide. An adjustable base on the apparatus varies the width of an open space in which a tack strip to be installed is positioned and located. The base gap width thus can be adjusted to position differing width tack strips as necessary. A central hammer equipped with an impact head is hit with a conventional hammer or the like, when the tack strip nailer is located above a spot in the tack strip where it is desirous to hammer a nail to secure the tack strip. The hammer can be equipped with a magnetic tip portion for holding and properly orienting nails to be installed. Additionally, the hammer is adjustable in its longitudinal position over the tack strip allowing the proper placement of the hammer to correspond with different tack strip widths.Type: GrantFiled: June 19, 1978Date of Patent: May 27, 1980Inventor: Travis A.

Patent number: 4161272Abstract: A nail driver for driving nails into a receiving surface comprises a housing with a release member movable upwardly and downwardly in the housing having a lower end which is engageable with the receiving surface. A nail guide channel is defined in the housing and it is arranged in association with a magazine for feeding nails into the channel in succession. A nail driver bar is movable upwardly and downwardly in the channel over the nail. A compression spring is engaged between the lower end of the release member and the nail driver so that when the release member is pressed against a surface, it may move upwardly against the force of the compression spring. The control mechanism is actuated by displacement of the release member to effect driving of a windup drum for a drive tape which is wound around the drum and connected at its free end to the upper end of the nail driver.Type: GrantFiled: November 29, 1977Date of Patent: July 17, 1979Assignee: Mafell-Maschinenfabrik Rudolf Mey KGInventor: Walter Brockl

Patent number: 4120438Abstract: An apparatus for driving a nail into a relatively inaccessible surface. The nail driver includes an elongated cylindrical housing having a bore extending between its front and rear ends, the rear end covered by an end cap. A rigid rod of lesser diameter than the bore of the housing is slidably received in the bore, with the rear end of the rod projecting rearwardly through the end cap when the front end of the rod is adjacent the front end of the housing. The rear end of the rod carries a weighted handle. The front end of the rod includes a magnetized end portion of about the same diameter as the bore of the housing. A first compression spring extends between the end cap and the weighted handle to absorb the momentum of the weighted handle at the forward end of a stroke, and a second compression spring surrounds the rod within the housing and extends between the end cap and the end portion of the rod for resiliently biasing the rod in a forward direction.Type: GrantFiled: March 7, 1977Date of Patent: October 17, 1978Inventor: Ivan J.

Patent number: 4042036Abstract: This invention relates to an electric impact tool characterized by a pair of electric motor-driven counterrotating flywheels, at least one of which is movable relative to the other from a retracted inoperative position into an extended operative one closely adjacent the other flywheel whereby a ram is squeezed therebetween and impelled forward at high speed against a workpiece. The nosepiece of the tool frame is retractable although normally extended due to the spring bias urging it and the movable flywheel to which it is mechanically linked into disengaged position. These elements cooperate with one another and with a manually-actuated trigger such that the latter must be depressed and the nosepiece retracted in order to engage the high energy friction clutch defined by the flywheels so as to operate the ram. A flywheel speed control is provided for matching the ram impact to the workload.Type: GrantFiled: May 23, 1975Date of Patent: August 16, 1977Inventors: James E. Smith, James D. Cunningham

Patent number: 3934779Abstract: An improved fastener driving tool having particular utility at locations that are otherwise inaccessible is disclosed. The fastener driving tool of this invention includes an elongated cylinder having one closed end. A ram is slidably mounted in the cylinder so that one end of the ram bears against the inside surface of the closed end of the cylinder. An axially displaceable rod is mounted on the outside surface of the cylinder and includes a clip that is adapted to hold the head of the nail against the outside surface of the closed end of the cylinder. With the nail so positioned the tool may be inserted behind a wall, for example through a pre-existing window opening, so that a header may be secured to a stud. By using the tool of the present invention, it is not necessary to remove any plaster or wallboard in order to expose the header and studs that are to be nailed. The ram is moved axially in two opposite directions within the cylinder until the nail is sufficiently started.Type: GrantFiled: October 31, 1974Date of Patent: January 27, 1976Inventor: Gilbert Dent
