Abstract
Abstract A wood splitting wedge is arranged on a vertical support such that the upper end of the wedge can be conveniently struck by a sledge hammer or the like in order to split a log provided immediately below the wedge and supported on a base which also serves to support the lower end of the support or standard. A second wedge is provided intermediate the first wedge and the standard and a handle serves to provide a convenient means for splitting small kindling with the second wedge. The second wedge serves the added function of spreading the sections of larger logs when they are being split in order to avoid jamming of the first wedge.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
A device for splitting logs or the like, and comprising a horizontally extending base for supporting a log to be split in a generally upright orientation, a fixed post carried by the base and extending upwardly therefrom, wedge means slidably mounted on said post for movement toward and away from said base, said wedge means including an elongated sleeve slidably received on said post and a tapered downwardly pointed wedge member spaced from the sleeve, said wedge member having an upwardly facing abutment surface adapted to be struck to drive the lower chisel edge of said wedge member into the log, said wedge means further including bracket means connecting said wedge member to said sleeve and a second wedge member also of downwardly tapered configuration and having a pointed lower chisel edge which defines an included angle slightly greater than that defined by said first mentioned wedge member.
Claim 2
Independent Claim
148 words
A device for splitting logs or the like, and comprising a horizontally extending base for supporting a log to be split in a generally upright orientation, a fixed post carried by the base and extending upwardly therefrom, wedge means slidably mounted on said post for movement toward and away from said base, said wedge means including an elongated sleeve slidably received on said post and a tapered downwardly pointed wedge member spaced from the sleeve, said wedge member having an upwardly facing abutment surface adapted to be struck to drive the lower chisel edge of said wedge member into the log, said wedge means further including bracket means connecting said wedge member to said sleeve and a second wedge member also of downwardly tapered configuration and having a pointed lower chisel edge which defines an included angle slightly greater than that defined by said first mentioned wedge member.
Claim 3
Dependent Claim
25 words
The combination defined in claim 1 wherein said second wedge member has an upper end which is wider than that of said first wedge member.
Claim 4
Dependent Claim
37 words
The combination defined in claim 1 wherein said second wedge member has its pointed lower chisel edge spaced above that of said first wedge member, both said lower pointed chisel edges residing in a common vertical plane.
Claim 5
Dependent Claim
25 words
The combination defined in claim 3 wherein said second wedge member has an upper end which is wider than that of said first wedge member.
Claim 6
Dependent Claim
58 words
The combination defined in claim 3 wherein said bracket means further includes a handle portion extending from a point just below the upper abutment surface of said first wedge member toward said sleeve to connect said first wedge member with said sleeve and defining a space between said handle and the upper end of said second wedge member.
Claim 7
Dependent Claim
24 words
The combination defined in claim 5 wherein said post is of generally non-circular cross section, and said sleeve is non-rotatably but slidably received thereon.
Claim 8
Dependent Claim
25 words
The combination defined in claim 5 wherein said second wedge member has an upper end which is wider than that of said first wedge member.
Claim 9
Dependent Claim
31 words
The combination defined in claim 6 further characterized by removable stop pin means associated with said post to hold the wedge means in a predetermined vertical position relative to said base.
Claim 10
Dependent Claim
32 words
The combination defined in claim 8 further characterized by stop means to limit the down position of said wedge means and prevent contact between said first wedge chisel edge and said base.
