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
Background
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.
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.
Potential infringers should also be aware that in cases of willful
infringement, a court may increase the damages up to three times. A court may
also order a permanent injunction. Link - More information about intellectual
property infringement.
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 systemby 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."

Reversing Mushroom AngleGraver™
Our PalmGraver® can be configure to have a low angle of
attack, or a high angle of attack to the work. See video to the left
how to switch it back and forth by reversing. The tool hole in the
nose is .133" in diameter. So 3/32" square graver shanks fit as well
as 1/8" round, or any size that will fit in the .133" hole.

there is any question send us a photo of your push graver and we can let
you know if this burl handle will fit.

Benefits of high angle of attack:
*Clearance and hand comfort
* Bulino dots and dashes.
* Extra heel clearance for less drag.
* Inside ring engraving.
* Hard to otherwise access concave surfaces.
*Improved viewing when using the microscope while stippling and while gold
inlaying.
Benefits
of low angle of attack: *Clearance and hand comfort
* Line engraving, partially with manual push
engraving.
AngleCollet™
Click to Enlarge
The handpieces picture in the photo are the BenchJewel at the top and a
collet nosed burl handle PalmControl. The bottom two handpieces in
the photo are foot controlled collet nosed Classics with AngleCollet
that is rotated opposite to illustrate a high angle of attack and low
angle of attack. Two adapters are also in the photo which are used
on long collets.
Similar to the reversing manual AngleGraver these
collets are angled and are reversible. With the AngleCollet the handle
does not need to be reversed to switch from low angle to high angle of attack.
In order to change between the two modes pull out the AngleCollet, rotate and
reinsert it.
Reversing AngleCollets are available with and without
offset.

The clearance created with the angled graver steep is
great for hard to access concave surfaces. For example
here is the engraving in the bottom of a spoon by
Marius
Mellebye. A place that
is notoriously difficult area to get to. The AngledGraver
together with the "Extra High Angle" ground point is able to get in to
engrave it.
Most of the V templates that
have a uniform parallel heel can be utilized for a bulio template by
simply not placing the heel on it which is done with V part of the large
template.

template page So skip that step while sharpening and it will make
point dig right in for making a dot or dash. Information about
bulino can be found at
