Angled shear safety guide splitting system for wood/log splitters
FIELD OF THE INVENTION
[001] The present invention relates generally to lumber equipment but more
particularly to an angled shear safety guide splitting system for wood/log
splitters.
BACKGROUND OF THE INVENTION
[002] Log splitting machines have been around for over a century, starting
with steam powered splitters to accelerate the work of manual splitting
using an ax. Nowadays, with hydraulic system powered by diesel, gas,
or even electric motors, it becomes even easier and faster. Still, there is
some room for improvement, more specifically with the cutting blade, or
wedge. Typically, a splitting wedge is shaped like an isosceles triangle
with the apex being the cutting member and onto which a log is pushed.
The sides of the wedge splay the log as it passes along them. The angle
of the wedge makes the log splay quite a lot and thus requires a strong
pressure from the piston to continue the splitting of the log which is as
much accomplished by the splaying than it is by the sharpness of the tip
of the wedge. That splaying action, can be accomplished even if the
width of the wedge is smaller than the diameter of the log. It does,
1
CA 2876800 2019-02-05

however, require more force coming from the piston pushing the log. An
optimal angle and size has to be found so as to make it possible to split
a log with a less powerful piston. When jamming of any object, it
requires more power. When shearing an object it requires 50% less
power or force.
SUMMARY OF THE INVENTION
[003] It is a main advantage of this invention to provide for a shear having
optimal characteristics to split logs or planks while using a less powerful
piston by way of shearing.
[004] In order to do so, the angled shear safety guide log splitting system
has
an elongated frame having parallel elongated guides attached thereto. A
pressure plate adapted to be pushed by a utility piston and slide along
the guides in a linear direction, and an angled shear member having a
cutting edge member that is located at a distal end of the frame, wherein
the angled shear member is shaped and positioned upon the frame at
an angle such that a top portion of the cutting edge member is adapted
to touch a log positioned upon the frame first followed successively
downwardly by the rest of the cutting edge member to thereby more
easily and efficiently split the log when pushed by the pressure plate.
2
CA 2876800 2019-02-05

[005] The log splitting system has the frame member formed in the shape of
an "I" beam.
[006] The log splitting system has the elongated guides "L" shaped and
securely attached to opposite sides of the "I" beam.
[007] The log splitting system has the pressure plate shaped to engage both
the elongated guides such that it can smoothly move in a back-and-forth
linear direction thereon.
[008] The log splitting system wherein the pressure plate includes a flat
portion having a series of ridges thereon adapted to engage, hold, and
push the log into the shear member.
[009] The log splitting system has the cutting edge member formed having a
front edge cutting angle having a width that is chosen and adapted to
split the log into thin kindling strips.
[0010] The log splitting system is further comprised of a utility piston
connected
between the frame and the pressure plate and adapted to push the
pressure plate along the guides in a linear direction.
[0011] There has thus been outlined, rather broadly, the more important
features of the invention in order that the detailed description thereof
3
CA 2876800 2019-02-05

that follows may be better understood, and in order that the present
contribution to the art may be better appreciated. There are additional
features of the invention that will be described hereinafter and which will
form the subject matter of the claims appended hereto.
[0012] In this respect, before explaining at least one embodiment of the
invention in detail, it is to be understood that the invention is not limited
in its application to the details of construction and to the arrangements
of the components set forth in the following description or illustrated in
the drawings. The invention is capable of other embodiments and of
being practiced and carried out in various ways. Also, it is to be
understood that the phraseology and terminology employed herein are
for the purpose of description and should not be regarded as limiting.
[0013] As such, those skilled in the art will appreciate that the conception,
upon
which this disclosure is based, may readily be utilized as a basis for the
designing of other structures, methods and systems for carrying out the
several purposes of the present invention. It is important, therefore, that
the claims be regarded as including such equivalent constructions
insofar as they do not depart from the spirit and scope of the present
invention.

various
features of novelty which characterize the invention, are pointed out with
particularity in the claims annexed to and forming a part of this

is DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0019] An angled shear safety guide splitting system (10) for wood/log
splitters
has an elongated frame (12) comprised of two elongated and parallel
guides (14) and a slidable pressure plate (16). The pressure plate (16)
5
CA 2876800 2019-02-05

moves linearly along the guides (14) while being pushed by a utility
piston (not shown). The frame (12) is formed in the shape of an "I" beam,
and the guides (14) are "L" shaped.
[0020] The pressure plate (16) is configured and shaped to engage both the
elongated guides (14) so as to move smoothly linearly, back and forth
thereon.
[0021] A log (22), is pushed by the pressure plate (16) onto an angled shear
member (18). The angled shear member (18) has a slight forward lean to
make a top portion (19) of an edge member (20) touch the log first,
lo followed
progressively downward by the rest of the edge member (20).
The angled shear member (18) is more efficient than a traditional splitter
(not shown) specifically because of the forward lean and the edge
member (20) has an edge angle that is very small so as to be very thin in
its width.
is [0022] This angle
allows for a splitting with a smaller splaying of the log, and as
such requires less pressure force from the pressure plate (16). This also
impacts on the strength required on other components of the splitting
system (10), and makes them smaller, lighter and thus a more practical
machine. Because of the reduced splaying and the thinness of the edge
20 member (20), It is
possible to split logs or planks into thin kindling strips.
6
CA 2876800 2019-02-05

The pressure plate (16) includes a flat portion (24) having a series of
ridges (26) thereon adapted to engage, hold, and push the log into the
shear member (18).
[0023] As to a further discussion of the manner of usage and operation of the
present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.
[0024] With respect to the above description then, it is to be realized that
the
optimum dimensional relationships for the parts of the invention, to
to include variations in size, materials, shape, form, function and manner
of
operation, assembly and use, are deemed readily apparent and obvious
to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention.
is [0025] Therefore, the foregoing is considered as illustrative only of
the
principles of the invention. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not desired to
limit the invention to the exact construction and operation shown and
described, and accordingly, all suitable modifications and equivalents
20 may be resorted to, falling within the scope of the invention.
