Bracket connection for backhoe and skip loader

In a coupling mechanism for attaching an implement to the control arms of a backhoe or the like wherein a first coupling member is mounted on the control arms for engagement with a second coupling member carried by the implement, the improvement which comprises spaced bars carried by said second coupling member to define a socket and providing abutment means extending transversely across substantially the entire width of said implement. a plate carried by said first coupling member and having an upper end portion adapted to be inserted into said socket, transverse means on said first coupling member adapted for movement into contact with said abutment means as said plate is moved into said socket, and locking means for holding said coupling members together when said plate is disposed in said socket, said transverse means including a bar extending across the first coupling member and an abutment surface on said plate, said last-mentioned bar and surface being movable into stress-transmitting engagement with the spaced bars of said second coupling member.

In a coupling mechanism for attaching a bucket to the control arms of a backhoe or the like in which a first coupling member is mounted on the control arms for engagement with a second coupling member carried by the implement, the improvement wherein said second coupling comprises rearward extensions on the side walls of the bucket, a beam extending between said extensions rearwardly of the back wall of the bucket, a pair of bars extending between said side walls in spaced relation to define a socket on said bucket near the upper rearward end thereof, and wherein said first coupling member comprises a hitch including a pair of upright arms pivoted on a common axis from the control arms of the hoe, a plate secured to the leading edges of said arms to extend in a plane parallel to the pivot axis of said arms, and a bar secured between said arms closely adjacent the rear face of said plate, the bar on said hitch being movable into abutting contact with one of the bars on said bucket when said plate is moved into said socket, and the leading edges of the arms of said hitch being movable into engagement with said beam incident to the movement of said plate into said socket.

In a coupling mechanism for attaching an implement to the control arms of a backhoe or the like wherein a first coupling member is mounted on the control arms for engagement with a second coupling member carried by the implement, the improvement which comprises transversely extending parallel members defining a socket on said second coupling member, a transverse plate carried by said first coupling member with its transverse faces engaging said members in abutting relation to link said coupling members together at a first juncture area, and a pin connecting said coupling members together at an area spaced from said first area, said transverse faces of said plate having pressure-transmitting contact with said socket-defining members for transmitting pressure to the implement in directions generally longitudinally of the implement, one of said socket-defining members being in contact with a portion of said first coupling member to transmit downward pressure to said first coupling member throughout a major portion of the width of the implement.
