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 and extensions
A bent 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. Thus, 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 surfaces. In more recent times power hand engravers have come in existence. The 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. The above photo illustrates a low angle of attack and a high angle of attack to the work surface with the angled engraver invention. |

We take intellectual property seriously
Each of our angled gravers, angled collets and angled
extensions are marked with the patent number and patent pending. This provides
potential infringers constructive notice of our patent rights, which means
that in a patent infringement lawsuit, damages can be awarded for infringement
that took place before the lawsuit was filed or the infringer was given actual
notice of the infringement, such as, a warning letter. In other words, the
longer the infringement, the greater the damages an infringer can be assessed.
Infringers will typically argue that the invention
was already known but this line of argument is very difficult to support.
Quote from An insight on the US Patent system by Michael Artemis
"Correspondingly, although someone may claim to have seen what they consider
the same invention years ago, if the alleged prior invention was not
documented or publicly available, it may not qualify as prior art with respect
to the invention. When the Patent Office issues a patent, it is cloaked with a
VERY powerful presumption of validity." |
