STATES PATENTS 541,038 6/1895 Clark ..145/46 ux NAIL DRIVER This invention relates to specialized nail and driver apparatus in the upholstery industry for use preferably in attaching panels on overstuffed furniture. Normally, thin panels of wood are covered by material and attached to places like the front of overstuffed arms, wings, etc. This invention allows the panel to be attached without having to glue it on because glue does not hold satisfactorily enough. The invention also obviates the necessity of driving the nail into the material where it is conspicuous to the viewer. Although the nail can be driven in and sunk into cloth material so that the head is not visible, this cannot be done with certain types of coverings such as plastics, leathers, etc.

Accordingly, a primary object of this invention is the efficient attachment of wood panels to furniture without detracting from the aesthetic appearance of the furniture.

Another object of this invention is the facilitation of the attachment process.

The above and other objects of this invention will become apparent to those skilled in the art after a consideration of a detailed description of a preferred embodiment of this invention taken together with the accompanying drawing wherein:

FIG. 1 is an elevational view of the apparatus;

FIG. 2 is a sectional view taken on the line 22 of FIG. 1; and

FIG. 3' is a sectional view taken on the line 3-3 of FIG. 2.

Referring in detail to the drawing, there is shown a plain nail portion and a knurled nail portion 12 extending from opposite sides of a solid washer 14. A rod 16 having a bore 18 in one end thereof is mounted on washer 14 with knurled portion 12 inserted within bore 18. Secured to the bottom of bore 18 is a magnet 20 having a conical groove 22 in the front face thereof pulling the pointed end of knurled portion 12 into a mated fit with groove 22.

The plain portion 10 is first driven into the frame of a piece of furniture. Washer 14 limits the depth to which the device is driven. After sufficient nails have been driven into the proper location, the panel is placed into position and tapped down onto the knurled portions 12 and held securely thereby. Plain portion 10 is positioned and driven by the use of rod 16 and magnet 20.

While a preferred embodiment has been illustrated and described, it should be understood by those skilled in the art that many changes and modifications may be resorted to without departing from the spirit and scope of this invention.

1 claim:

1. A nail driver apparatus for driving magnetizable nails of the type including a disc and a pointed shaft integrally formed on and extending from each side of said disc, comprising a generally cylindrical elongated rod, a socket formed axially in one end of said rod having a diameter substantially greater than said pointed shafts, a magnet seated in the inner end of said socket and having an exposed face extending transversely of said socket, and a conical socket formed axially in said face to receive'the pointed end of one of said shafts under magnetic attraction to axially align said nail with said rod.
