Abstract
Abstract An apparatus for splitting logs into billets and having a pivoting splitter head mounted at one end of an elongated log support upon which logs are placed for splitting. The splitter head is supported by a pin extending from a splitter head mount attached to the log support toward a pusher that forces the log into the splitter head. Platforms are attached to the pusher and extend therefrom along the sides of the log support to receive the billets into which a log is split, the attachment of the platforms to the pusher maintaining the platforms in lateral alignment with the log as the log is split. The apparatus is mounted on a wheeled chassis having a trailer tongue at one thereof for towing the apparatus to a work site.

Claim 1
Independent Claim
334 words
an apparatus for splitting a log into billets, comprising: an elongated log support for receiving a log thereon; log drive means for driving the log along a drive path toward one end of the log support; and a splitter assembly mounted on the log support at said one end thereof for splitting the log into billets as the log is driven into the splitter assembly by the log drive means, the splitter assembly comprising: a splitter head mount secured to the log support to extend into said drive path; and a splitter head pivotally supported on the splitter head mount between the splitter head mount and the log drive means for pivotal movement on the splitter head mount about an axis extending along said drive path, the splitter head having a splitter edge formed on one side thereof facing away from said one end of the log support and the splitter head comprising: a first splitter section extending laterally of the pivot axis of the splitter head on the splitter head mount and having a portion of the splitter edge formed thereon; and a second splitter section extending laterally of the pivot axis of the splitter head on the splitter head mount and having a portion of the splitter edge formed thereon, the second splitter section extending from said pivot axis in a direction opposite the extension of the first splitter section from said pivot axis; and said second splitter section has a greater lateral extent from said pivot axis than the lateral extent of the first splitter section from said pivot axis; whereby when large diameter logs are to be split, the splitter head can be supported on said splitter mount so that said second section is above said first section, thereby increasing the vertical extent of the splitter head from said log support; and when small diameter logs are to be split said splitter head can be supported on said splitter mount so that said first section is above said second section.
Claim 2
Independent Claim
334 words
an apparatus for splitting a log into billets, comprising: an elongated log support for receiving a log thereon; log drive means for driving the log along a drive path toward one end of the log support; and a splitter assembly mounted on the log support at said one end thereof for splitting the log into billets as the log is driven into the splitter assembly by the log drive means, the splitter assembly comprising: a splitter head mount secured to the log support to extend into said drive path; and a splitter head pivotally supported on the splitter head mount between the splitter head mount and the log drive means for pivotal movement on the splitter head mount about an axis extending along said drive path, the splitter head having a splitter edge formed on one side thereof facing away from said one end of the log support and the splitter head comprising: a first splitter section extending laterally of the pivot axis of the splitter head on the splitter head mount and having a portion of the splitter edge formed thereon; and a second splitter section extending laterally of the pivot axis of the splitter head on the splitter head mount and having a portion of the splitter edge formed thereon, the second splitter section extending from said pivot axis in a direction opposite the extension of the first splitter section from said pivot axis; and said second splitter section has a greater lateral extent from said pivot axis than the lateral extent of the first splitter section from said pivot axis; whereby when large diameter logs are to be split, the splitter head can be supported on said splitter mount so that said second section is above said first section, thereby increasing the vertical extent of the splitter head from said log support; and when small diameter logs are to be split said splitter head can be supported on said splitter mount so that said first section is above said second section.
Claim 3
Dependent Claim
57 words
The apparatus of claim 1 wherein the splitter head mount is characterized as comprising a splitter head mounting pin axially extending along the drive axis; wherein the splitter head is characterized as having a socket formed therein to receive said pin; and wherein the splitter head assembly further comprises means for securing said socket about said pin.
Claim 4
Dependent Claim
79 words
The apparatus of claim 2 wherein a circumferential groove is formed about portions of the splitter head mounting pin disposed within said socket; wherein a hole is formed through portions of the splitter head to intersect portions of the socket extending about the groove in the splitter head mounting pin; and wherein the means for securing the socket about the pin comprises a bolt extending through said hole to engage portions of the pin wherein said groove is formed.
Claim 5
Dependent Claim
34 words
The apparatus of claim 1 wherein portions of the splitter edge to either side of the splitter head pivotation axis are canted in a direction generally toward said one end of the log support.
Claim 6
Dependent Claim
36 words
The apparatus of claim 1 or 2 wherein portions of the splitter edge to either side of the splitter head pivotation axis are canted in a direction generally toward said one end of the log support.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1 further comprising catcher means disposed alongside the log support for receiving the billets thereon.
Claim 8
Dependent Claim
100 words
The apparatus of claim 6 wherein the log drive means comprises: a pusher slideably disposed on the log support for movement along the drive path; and means for alternatively moving the pusher toward and away from said one of the log support; and wherein the catcher means comprises: a first catcher platform disposed along one side of the log support and attached to the pusher for movement therewith parallel to the drive path; and a second catcher platform disposed along the opposite side of the log support and attached to the pusher for movement therewith parallel to the drive path.
