Abstract
Abstract A quick attachment carrier assembly (10) for releasably connecting an attachment (12) to a front end loader (14) comprises a pair of carriers (24) with top and bottom notches therein adapted to receive transverse pins (40, 42) on the implement. Pivotal hooks (46) are provided on the carriers (24) for engagement with the pins (42) for interconnecting the implement (12) to the loader (14). The latch hooks (46) are preferably secured together and controlled in common by means of a single lever (52) and plunger (56) which permit positive locking of both hooks in either the latched or unlatched positions.

Claim 1
Independent Claim
201 words
Apparatus for releasably connecting a material handling attachment to a loader, comprising: a pair of laterally spaced apart upper transverse pins secured to the attachment; a pair of laterally spaced apart lower transverse pins secured to the attachment beneath said upper transverse pins; a pair of laterally spaced apart carriers secured to the front end loader, each carrier including an upwardly open top notch adapted to receive an upper transverse pin and a forwardly open bottom notch adapted to receive a lower transverse pin; a hook mounted on at least one of said carriers for pivotal movement between a latched position in engagement with the corresponding lower transverse pin and an unlatched position; handle means for manually actuating said hook between the latched and unlatched positions; and means for releasably locking said hook in either position; said releasable locking means including; a latch plate mounted on said carrier adjacent said hook with holes therein corresponding to the latched and unlatched positions of said hook; a locking pin mounted on said hook for movement toward and away from said latch plate; and means for normally biasing said locking pin toward a locked position in registry with either hole in said latch plate.

Apparatus for releasably connecting a material handling attachment to a loader, comprising: a pair of laterally spaced apart upper transverse pins secured to the attachment; a pair of laterally spaced apart lower transverse pins secured to the attachment beneath said upper transverse pins; a pair of laterally spaced apart carriers secured to the front end loader, each carrier including an upwardly open top notch adapted to receive an upper transverse pin and a forwardly open bottom notch adapted to receive a lower transverse pin; a hook mounted on at least one of said carriers for pivotal movement between a latched position in engagement with the corresponding lower transverse pin and an unlatched position; handle means for manually actuating said hook between the latched and unlatched positions; and means for releasably locking said hook in either position; said releasable locking means including; a latch plate mounted on said carrier adjacent said hook with holes therein corresponding to the latched and unlatched positions of said hook; a locking pin mounted on said hook for movement toward and away from said latch plate; and means for normally biasing said locking pin toward a locked position in registry with either hole in said latch plate.
Claim 3
Dependent Claim
199 words
Apparatus for attaching a front end loader to an attachment having laterally spaced apart vertical pairs of transverse pins mounted thereon, which comprises: a pair of laterally spaced apart carriers pivoted to the front end loader, each carrier including an upwardly open top notch adapted to receive an upper transverse pin and a forwardly open bottom notch adapted to receive a lower transverse pin on the attachment; a pair of hooks, one hook being pivoted to each carrier for movement between a latched position and in engagement with the corresponding lower transverse pin and an unlatched position out of engagement therewith; means for rigidly interconnecting said hooks; handle means for manually actuating said hooks in unison; and means mounted on one carrier for releasably locking said hooks in unison in either position; said locking means including: a latch plate mounted on said one carrier adjacent the corresponding hook with holes therein corresponding to the latched and unlatched positions of said hooks; a locking pin mounted on said corresponding hook for movement toward and away from said latch plate; and means for normally biasing said locking pin toward a locked position in registry with either hole in said latch plate.
