BRADSET

Abrégé anglais

A tool designed to improve the ability to set or recess mechanically driven
fasteners used
in woodworking and finish carpentry. The bradset is a striking tool having an
elongated metal
body, an impact end and contact tip to deliver the impact to the fastener. The
tip is suitably
shaped to match the specific fastener.

Revendications

What is claimed:
1. A striking tool, comprising: an elongated metal body having an upper impact
face for
receiving the impact of a hammer or the like; and a shaped tip to engage the
head of
mechanically driven fasteners.
2. A striking tool as recited claim 1, where the tip of said tool is sized and
shaped for T head
brad nails.
3. A striking tool as recited claim 1, where the tip of said tool is sized and
shaped for L head
flooring cleats.
4. A striking tool as recited claim 1, where the tip of said tool is sized and
shaped for clipped
head nails.
5. A striking tool as recited claim 1, where the tip of said tool is sized and
shaped for staples.

Bradset
Field of the Invention
The present invention relates to the f eld of carpentry and woodwork, in
particular where
the use of mechanically driven fasteners or the like are used.
Background of the Invention
Nail sets are commonly used in finish carpentry and woodworking to recess the
head of a
hand driven nail below the work surface. Such nail sets are typically formed
from an impact
resistant material such as hardened tool steel, and have a body which is
gripped by the user, a
head portion which is struck with a hammer, and a conical tip to engage the
circular nail head.
Presently the use of hand driven nails is being replaced by the use of
pneumatic,
mechanical or combustion driven nail guns. The fasteners used in these nail
guns typically do not
have the circular heads of hand driven nails, but rectangular. The use of
circular tipped nail sets
currently available on these fasteners present the user with numerous
problems. Because the nail
set tip does not properly conform to, nor fully engage the total fastener
head, offset strikes tend to
bend the fastener rather than set it. If the nail set is sized to engage the
outer edges of the
fastener, a larger than necessary divot will be created in the work piece
which is undesirable.
Summary of the Invention
The presented invention addresses these problems by introducing nail sets with
tips
specifically shaped and sized to corresponding fasteners.
Accordingly, it is the object of this invention to provide a tool which is
designed to
accurately engage the specific head of the fastener, as well as directly and
axially impact the head
for countersinking.

Brief Description of the Drawings
The advantages of the presented invention will become apparent to those
skilled in the art
upon reading the detailed description of the preferred embodiments taken in
conjunction with the
accompanying drawings in which:
Fig.l is a orthographic view of a typical brad set.
Fig.? is a front view of a typical Bradset sized and shaped for a T-head brad
nail, where
(I) is the tip of the Bradset and (2) is the T-head brad nail.
Fig.3 is a side view of a typical Bradset sized and shaped for a T-head brad
nail, where
(1) is the tip of the Bradset and (2) is the T-head brad nail.
Fig.4 is a front view of a typical Bradset sized and shaped for a medium crown
staple,
where (3) is the tip of the Bradset and (4) is the medium crown staple.
Fig.S is a side view of a typical Bradset sized and shaped for a large crown
staple,where
(3) is the tip of the Bradset and (4) is the medium crown staple.
Detailed Description of the Preferred Embodiment
Referring to the drawings for the purpose of illustrating a preferred
embodiment of the
presented invention and not for limiting same, FIG. 2 and FiG. 3 show a
bradset for use in
recessing mechanically driven fasteners of various sizes beneath the surface
of the work piece.
The typical bradset consists of a striking face (a) to be impacted with a
suitable tool such as a
hammer, an elongated main body (b) and a specifically shaped tip (c) to fully
engage the head of
the fastener.
The exact shape and dimensions of the tip correspond to the head of the
fastener for
which it is designed.
While the above features and advantages of this invention have been described
with
reference to a preferred embodiment of the bradset. other renditions will
become apparent to
those skilled in the art. Accordingly, the presented invention embraces all
subsequent renditions
and are to be solely defined by the appended claims.
