U.S. Patent 10,661,596 - The invention relates to providing hand
held engravers that can hold a graver closer to parallel to the work while at
the same time raising the handle away from the work. The invention
is also reversible allowing a graver to be held at a steep angle to the work.
Benefits of the new angled engravers, collets
of Patent 10,661,596, and Pending Patent: The
traditional hand engraving tool which has been used for banknote and deeper
engraving has been in existence for centuries. It consists of a graver (also
known as a tool point, tool tip or graver) inset into a mushroom shaped handle
that is made to fit into the human hand. The engraving artist pushes the tool
tip through the metal. Ideally for this manual engraver, the lower and closer
to parallel the graver shank can be held to the work, the better. A help to
manual push engraving of the past was the use of a bent graver shank.
graver shank allowed the front portion of the graver shank to be held close to
parallel to the surface and yet allowed for the handle to be up and away from
the work surface which provided clearance for the operator's hand. In
more recent times, carbide has been utilized for gravers rather than
carbon steel gravers. Unfortunately, carbide
shanks cannot be bent as steel can be.
there is a need for powered and manual engraving tools that can hold a
graver shank at an angle from the tool's body, and allow
the straight graver shank to be used closer to parallel to the surface being
engraved. This provides the benefit of the past bent steel graver shanks, as
well as giving raised clearance for the operator's hand on the handle. There
is also a need for the opposite, that is, to have the graver shank held to a
steep angle to the surface being engraved, for various work operations by the
artist such as bulino, inside ring engraving and hard to access concave
In more recent times power hand engravers have come in existence.
invention is an improvement for removable collets to be angled in order
to hold the graver shank at an angle and thereby give the benefit of what
the bent graver shanks of the past provided. It is
also an improvement that the removable nose collets are reversible to
allow the user of the tool to rotate the insert so that the angled
graver shank will be held at a steep angle to the work for various
operations such as bulino, inside ring engraving and hard to
access concave surfaces.
