Abstract
Abstract A two-piece multiposition ripper attachment for a back hoe is disclosed. In a first position, the attachment is stored out of the way so as to not interfere with normal use of the back hoe. In a second position, the attachment and method is exposed so that the back hoe may be used as a ripper in one orientation and may be used to perform its normal functions in a second orientation.

Claim 1
Independent Claim
194 words
An attachment for use in conjunction with a movable bucket or the like, the front end of said bucket being adapted to be used to scoop material, the rear end of said bucket having at least one rearwardly projecting portion provided with at least one transverse aperture, said rear end of said bucket adapted to receive said attachment, said attachment comprising: a bracket portion provided with a plurality of apertures, a first of said apertures being adapted to removably attach said bracket portion to said rearwardly projecting portion; a scarifier portion comprising a shank and a bit, said shank being elongated, said bit attached to said shank in the proximity of one end of said shank, said shank being provided with at least one aperture; a pin adapted to pass simultaneously through another of said apertures in said bracket portion and an aperture in said shank portion to hold said scarifier portion in a first position with respect to said bracket portion, said pin being adapted to be removed and reinserted to align a second pair of apertures so as to hold said scarifier portion and said bracket portion in a second relative position.
Claim 2
Dependent Claim

An attachment for use in conjunction with a movable bucket or the like, the front end of said bucket being adapted to be used to scoop material, the rear end of said bucket having at least one rearwardly projecting portion provided with at least one transverse aperture, said rear end of said bucket adapted to receive said attachment, said attachment comprising: a bracket portion provided with a plurality of apertures, a first of said apertures being adapted to removably attach said bracket portion to said rearwardly projecting portion; a scarifier portion comprising a shank and a bit, said shank being elongated, said bit attached to said shank in the proximity of one end of said shank, said shank being provided with at least one aperture; a pin adapted to pass simultaneously through another of said apertures in said bracket portion and an aperture in said shank portion to hold said scarifier portion in a first position with respect to said bracket portion, said pin being adapted to be removed and reinserted to align a second pair of apertures so as to hold said scarifier portion and said bracket portion in a second relative position.
Claim 3
Dependent Claim
38 words
The attachment of claim 1 wherein the bracket portion comprises a pair of separated parallel side portions and an attaching portion, said side portions adapted to confine said shank therebetween, said shank being of substantially rectangular cross section.
Claim 4
Dependent Claim
27 words
The attachment of claim 2 wherein said attaching portion is adapted to be attached to said rearwardly projecting portion of said bucket by a transversely disposed pin.
Claim 5
Dependent Claim
73 words
The attachment of claim 2 wherein one of said shank and said pair of parallel side portions is provided with one aperture and the other is provided with two apertures so disposed that a first combination of said apertures may be pinably aligned to hold the scarifier portion in said first position and that a second combination of said apertures may be pinably aligned to hold the scarifier portion in said second position.
Claim 6
Independent Claim
107 words
The method of using a back hoe to break up and move a horizontally disposed crustaceous material comprising the steps of; attaching to the back hoe bucket in a first position a scarifier; revolving the bucket to a first orientation wherein the scarifier is exposed below the lower edge of the bucket; moving the bucket and attached scarifier horizontally so as to rip the material; revolving the bucket to a second orientation so that the scarifier is obscured behind the bucket; scooping up the thus loosened materIal into the bucket for removal and; moving the scarifier attachment to a second position for storage during periods of nonuse.
Claim 7
Independent Claim
107 words
The method of using a back hoe to break up and move a horizontally disposed crustaceous material comprising the steps of; attaching to the back hoe bucket in a first position a scarifier; revolving the bucket to a first orientation wherein the scarifier is exposed below the lower edge of the bucket; moving the bucket and attached scarifier horizontally so as to rip the material; revolving the bucket to a second orientation so that the scarifier is obscured behind the bucket; scooping up the thus loosened materIal into the bucket for removal and; moving the scarifier attachment to a second position for storage during periods of nonuse.
Claim 8
Dependent Claim
19 words
The method of claim 5 wherein the step of moving comprises making a plurality of substantially parallel ripping passes.
Claim 9
Dependent Claim
10 words
The method of claim 6 wherein said plurality is three.
Claim 10
Dependent Claim
55 words
The method of claim 5 wherein the step of moving the scarifier to its second position comprises the steps of sliding the scarifier attachment upwardly with respect to the bucket, and affixing it to the bucket in said second position so as to effectively store the scarifier in said second position during periods of nonuse.
