Abstract

Abstract A stump splitting blade with laterally spaced apart ears, each ear respectively formed with a respective hole, with said holes being in alignment; said ears being predeterminedly spaced to receive the terminal end portion of a tool carrier mounted on a powered vehicle, such as a tractor, or the like. Said tool carrier being formed with a hole which may be registered with said aligned holes to receive a connecting pin to operably mount the stump splitting assembly on the carrier. Said blade being formed with a downwardly extending notch, with opposed, upwardly divergent edge surfaces defining said notch, and receiving between said surfaces the terminal end portion of said tool carrier; stop plates extending between said ears, and being spaced forwardly and rearwardly of said connecting pin, said stop plates occupying upwardly divergent planes to present opposed and upwardly divergent surfaces to said terminal end portion of said tool carrier. The angle of said divergency being such as to cause the engagement of the tool carrier with one or the other of said stop plates to limit otherwise permissible angular travel of the blade about the axis of said connecting pin. The terminal end portion of said tool carrier is formed with an arcuate surface concentric with the hole formed therein, whereby insertion of said terminal end portion between said inclined stop plates, will cause engagement of said arcuate surface with said opposed inclined surfaces of said stop plate, and result in registration of the hole formed in said tool carrier with said aligned holes in said ears to facilitate insertion of said connecting pin.

Claims Analysis

Total Claims: 9

Claim 1

Independent Claim 104 words

The combination with a vehicle having a power source, and a tool carrier carried by said vehicle for at least up and down travel thereon, and a power transmission from said power source to said carrier to effect such travel, of a tree stump splitting assembly, including, a blade, adapted to be mounted on said carrier to be operably carried in said up and down travel, at least one ear secured to said blade, a hole formed in said ear, a hole formed in said carrier, registrable with said hole in said ear, and a connecting pin or the like received in said holes.

Claim 2

Dependent Claim 104 words

Claim 3

Dependent Claim 35 words

The combination as set forth in claim 1, said tree stump splitting assembly having limited angular travel about the longitudinal axis of said connecting pin, and means on said assembly to limit said angular travel.

Claim 4

Dependent Claim 74 words

The combination as set forth in claim 2, a downwardly extending notch formed in said blade, said notch having opposed spaced edge surfaces defining said notch, said ear being secured to said blade laterally of said notch, and said tool carrier having predeterminedly contoured surfaces, and said notch being proportioned to receive said surfaces, and said edges of said notch engaging said surfaces to limit the angular travel of said blade about said axis.

Claim 5

Dependent Claim 46 words

The combination as set forth in claim 3, stop plates rigidly secured to said ear, in spaced relationship to each other, said contour of said carrier being received between said stop plates, and engageable with said stop plates to limit said angular travel in either direction.

Claim 6

Dependent Claim 95 words

The combination as set forth in claim 1, a second ear spaced apart from said first mentioned ear, said ears flanking and being secured to said blade, a respective hole formed in each respective ear, said respective ears being in alignment, said tool carrier having a terminal end portion, said ears being spaced to receive said terminal end portion therebetween, a hole in said terminal portion, said hole being registrable with said aligned holes, and a connecting pin or the like received in said aligned and registered holes to mount said assembly on said carrier.

Claim 7

Dependent Claim 22 words

The combination as set forth in claim 5, means to engage said terminal portion of said carrier to limit said angular travel.

Claim 8

Dependent Claim 50 words

The combination as set forth in claim 5, a pair of spaced stop plates extending between said pair of ears, said plates being disposed respectively forwardly and rearwardly of said connecting pin to engage said carrier to limIt said angular travel in either direction about the axis of said pin.

Claim 9

Dependent Claim 79 words

The combination as set forth in claim 7, an arcuate surface formed on said terminal end portion of said tool carrier, said surface being concentric with said hole formed in said carrier. said stop plates being upwardly divergent at a predetermined angle such that contact of said arcuate surface with both opposing faces of said stop plates substantially registers said hole in said carrier with said respective aligned holes to facilitate insertion through said holes of said connecting pin.
