Abstract

Abstract An adapter assembly for quickly attaching and releasing an implement from a pair of spaced actuating arms, useful typically to mount a bucket to the loader arms and tilt cylinders of a front-end loader. The adapter assembly is permanently pinned to the loader arms and tilt cylinders of the front-end loader and releasably attached to the bucket. It is characterized by an elongate member extending substantially the distance between the loader arms and means spaced from the elongate member for releasably securing the adapter assembly to the bucket. The elongate member seats under an acute overhang at the upper rear wall of the bucket and the lower portion of the adapter is releasably secured to a protruding shelf at the lower rear wall of the bucket.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 126 words
A quick attachment and release device for attaching an implement to a pair of spaced actuating arms comprising: an elongate member adapted to substantially uniformly engage said implement throughout its length and extending substantially the distance between said spaced actuating arms; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms, and adapted to engage said implement, said elongate member and said actuating arm mounting brackets being adapted to wedge against said implement when urged into engagement therewith; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said implement comprising a pair of hooks pivotally mounted to said respective mounting brackets and adapted to wedgingly engage said implement.
Claim 2
Dependent Claim 126 words
A quick attachment and release device for attaching an implement to a pair of spaced actuating arms comprising: an elongate member adapted to substantially uniformly engage said implement throughout its length and extending substantially the distance between said spaced actuating arms; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms, and adapted to engage said implement, said elongate member and said actuating arm mounting brackets being adapted to wedge against said implement when urged into engagement therewith; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said implement comprising a pair of hooks pivotally mounted to said respective mounting brackets and adapted to wedgingly engage said implement.
Claim 3
Dependent Claim 57 words
The device of claim 1 wherein said elongate member is adapted to seat under an overhanging member mounted to said implement and extending substantially the length of said elongate member and said actuating-arm mounting brackets are adapted to wedge against a protruding shelf extending from said implement to thereby urge said elongate member into said seated engagement.
Claim 4
Dependent Claim 28 words
The device of claim 2 and spaced means on each of said brackets for respectively pivotally connecting said actuating-arm mounting brackets to said actuating arms and tilt cylinders.
Claim 5
Dependent Claim 151 words
Apparatus for quickly attaching and releasing an implement to a pair of spaced actuating arms comprising: an overhanging member mounted to a wall of said implement, extending substantially the entire distance between said spaced actuating arms, and defining an acute angle with said wall; a protruding shelf member spaced below said overhanging member and extending substantially the entire distance between said spaced actuating arms; an elongate member adapted to seat between said overhanging member and said wall and extending substantially the distance between said spaced actuating arms; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms and adapted to engage said protruding shelf member and simultaneously wedge said elongate member into seated engagement between said overhanging member and said wall; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said protruding shelf.
Claim 6
Dependent Claim 151 words
Apparatus for quickly attaching and releasing an implement to a pair of spaced actuating arms comprising: an overhanging member mounted to a wall of said implement, extending substantially the entire distance between said spaced actuating arms, and defining an acute angle with said wall; a protruding shelf member spaced below said overhanging member and extending substantially the entire distance between said spaced actuating arms; an elongate member adapted to seat between said overhanging member and said wall and extending substantially the distance between said spaced actuating arms; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms and adapted to engage said protruding shelf member and simultaneously wedge said elongate member into seated engagement between said overhanging member and said wall; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said protruding shelf.
Claim 7
Dependent Claim 18 words
The apparatus of claim 4 wherein said protruding shelf defines at least a perpendicular angle with said wall.
Claim 8
Dependent Claim 51 words
The apparatus of claim 5 wherein said releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said protruding shelf comprises a pair of hooks pivotally mounted to said respective mounting brackets and adapted to pivot into and out of engagement with openings in said shelf member.
Claim 9
Dependent Claim 18 words
The apparatus of claim 6 and resilient means for holding said hooks in engagement with said shelf member.
Claim 10
Dependent Claim 17 words
The apparatus of claim 7 wherein said resilient means operates upon a lever extending between said hooks.
Claim 11
Dependent Claim 127 words
A quick attachment and release device for attaching an implement to a pair of spaced actuating arms comprising: an elongate member adapted to substantially uniformly engage said implement throughout its length (and extending substantially the distance between said spaced actuating arms) and adapted to wedge against said implement when urged into engagement Therewith; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms, and adapted to engage said implement; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said implement including means for insuring wedging engagement between said elongate member and said implement despite wear and distortion which may occur between said elongate member and said implement during operation.
Claim 12
Dependent Claim 127 words
A quick attachment and release device for attaching an implement to a pair of spaced actuating arms comprising: an elongate member adapted to substantially uniformly engage said implement throughout its length (and extending substantially the distance between said spaced actuating arms) and adapted to wedge against said implement when urged into engagement Therewith; a pair of actuating-arm mounting brackets secured to said elongate member, extending transversely thereto, spaced substantially the distance between said actuating arms, and adapted to engage said implement; and releasable means spaced from said elongate member for securing said actuating-arm mounting brackets to said implement including means for insuring wedging engagement between said elongate member and said implement despite wear and distortion which may occur between said elongate member and said implement during operation.
