Abstract
Abstract An earthworking tip suitable for mounting on an adapter which is wedge-shaped in vertical cross section. The tip defines a rearwardly facing V-shaped projection which mates with a V-shaped opening in the adapter to transfer loads from the tip to the adapter. The tip has rearwardly extending upper and lower flanges to generally mate with the wedge-shaped adapter. Retaining means secure the tip upon the adapter.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
184 words
An earthworking tip and supporting adapter for mounting the tip, the adapter having a forward portion which is wedge-shaped in vertical cross section and defines a vertically aligned truncated V-shaped opening, the tip having rearwardly extending upper and lower flanges which diverge to generally mate with the wedge-shaped adapter portion and a rearwardly extending truncated V-shaped projection integrally formed between the flanges, said flanges extending past the truncated V-shaped projectiOn, the adjacent surfaces between said flanges and the upper and lower faces of said adapter being tapered inwardly from their sides toward their longitudinal center lines, said flanges being wider than and overhanging said adaptor, the truncated V-shaped projection of the tip generally mating with the truncated Vshaped opening of the adapter to permit load-transferring engagement between the surfaces of the truncated V-shaped opening in the adaptor and the truncated V-shaped projection of the tip, and means for securing the tip upon the adapter comprising a retaining pin disposed in a generally vertical bore formed through the wedge shaped adapter portion and tip flanges to the rear of the V-shaped opening in the adapter.
Claim 2
Dependent Claim
184 words
An earthworking tip and supporting adapter for mounting the tip, the adapter having a forward portion which is wedge-shaped in vertical cross section and defines a vertically aligned truncated V-shaped opening, the tip having rearwardly extending upper and lower flanges which diverge to generally mate with the wedge-shaped adapter portion and a rearwardly extending truncated V-shaped projection integrally formed between the flanges, said flanges extending past the truncated V-shaped projectiOn, the adjacent surfaces between said flanges and the upper and lower faces of said adapter being tapered inwardly from their sides toward their longitudinal center lines, said flanges being wider than and overhanging said adaptor, the truncated V-shaped projection of the tip generally mating with the truncated Vshaped opening of the adapter to permit load-transferring engagement between the surfaces of the truncated V-shaped opening in the adaptor and the truncated V-shaped projection of the tip, and means for securing the tip upon the adapter comprising a retaining pin disposed in a generally vertical bore formed through the wedge shaped adapter portion and tip flanges to the rear of the V-shaped opening in the adapter.
Claim 3
Dependent Claim
36 words
The invention of claim 1 wherein the load-transferring means includes keys integrally formed in both of the flanges and mating keyways formed in the adapter, said keys and keyways being formed along said inwardly tapering surfaces.
Claim 4
Dependent Claim
14 words
The invention of claim 2 wherein the keys are directly opposed to each other.
Claim 5
Dependent Claim
37 words
The invention of claim 1 wherein portions of the tip adjacent the wedge-shaped adapter portion are substantially symmetrical about a longitudinal, generally horizontal plane through the tip to permit reversible mounting of the tip upon the adapter.
Claim 6
Dependent Claim
26 words
The invention of claim 4 wherein a ground-engaging leading portion of the tip is in nonsymmetrical relation with the portions of the tip adjacent the adapter.
Claim 7
Dependent Claim
40 words
The invention of claim 1 wherein at least one of the rearwardly extending tip flanges and a portion of the adapter mating therewith include means effective to assist in transferring side loads on the tip to said mating adapter portion.
Claim 8
Dependent Claim
24 words
The invention of claim 6 wherein the load-transferring means include rearwardly extending lugs on the tip flanges and mating slots formed by the adapter.
Claim 9
Dependent Claim
35 words
The invention of claim 1 wherein the engagement between the surfaces of the V-shaped opening in the adapter and the V-shaped projection in the tip is along root surfaces formed in said adapter and tip.
Claim 10
Dependent Claim
57 words
The invention of claim 8 wherein the truncated V-shaped opening in the adapter and the truncated V-shaped projection of the tip have substantially equal angles of inclination and the rearwardly facing root surfaces of the truncated V-shaped projection having a smaller horizontal width than the forwardly facing root surfaces of the truncated V-shaped opening in the adapter.
Claim 11
Dependent Claim
173 words
An earthworking tip and supporting adapter for mounting the tip, the adapter having a forward portion which is wedge-shaped in vertical cross section and defines a vertically aligned truncated V-shaped opening, the tip having rearwardly extending upper and lower flanges which diverge to generally mate with the wedge-shaped adapter portion and a rearwardly extending truncated V-shaped projection integrally formed between the flanges, said flanges extending past the truncated V-shaped projection, said flanges being wider than and overhanging said adapter, the truncated V-shaped projection of the tip generally mating with the truncated V-shaped opening of the adapter along keys integrally formed in both of the flanges and mating keyways formed in the adapter to permit load-transferring engagement between the surfaces of the truncated V-shaped opening in the adapter and the truncated V-shaped projection of the tip, and means for securing the tip upon the adapter comprising a retaining pin disposed in a generally vertical bore formed through the wedge-shaped adapter portion and tip flanges to the rear of the V-shaped opening in the adapter.
Claim 12
Dependent Claim
173 words
