A blade sharpening assembly generally consisting of a support member having a first opening and at least a second opening spaced from the first opening, a blade holding assembly including a first member having a projecting section receivable in the first opening and cooperable with a portion of the support member for detachably securing the blade holding assembly in supported relation on the support member, a second member pivotally connected to the first member and means for pivoting one of the blade members relative to the other blade member about a fulcrum point to cause opposed end portions of the blade members to converge and engage a blade disposed therebetween in clamping relation, and a sharpening member including a sharpening stone engageable with a blade clamped between the blade holding sections, a longitudinally projecting guide rod receivable within the second opening in the support member and a gripping section which may be gripped to move the sharpening member with a reciprocating motion when the sharpening stone engages the blade and the guide rod is received within the second opening of the support member.

Blade sharpening assembly

A material handling assembly mountable on the handle of a machine generally having a bucket pivotally connectable to the handle and a device for pivoting the bucket about the pivotal connection of the bucket to the handle, an arm member pivotally connectable to the handle and cooperable with the bucket when mounted on the handle for clamping material therebetween, a bracket mountable on the handle having a guideway therein, a strut having a first section pivotally connected to the arm member and a second section received within and displaceable along the guideway, and a device for detachably securing the second section of the strut to the bracket at selected points along the length of the guideway.

Material handling assembly for machines and thumb assembly thereof

An assembly connectable to an operating arm of a machine for performing work functions comprising of an implement having a wall provided with an opening therein and a coupler including apparatus for detachably securing the coupler to the operating arm, apparatus insertable into the implement wall opening to an operative position having a selected angular relationship with the implement relative to a given axis and apparatus for securing the insertable apparatus in the operative position.

Assembly connectable to an operating arm of a machine for performing

An assembly for coupling an implement to an operating arm of a machine generally consisting of a first coupling component fixedly mountable on the implement, having a plurality of sets of opposed abutment surfaces spaced circumferentially relative to a given axis thereof and disposed substantially radially relative to such axis, and an axially spaced abutment surface, and a second coupling component disposable in mating relation with the first coupling component, having apparatus for detachably connecting to the operating arm, at least one locking member displaceable between an extended position and an retracted position received between a selected set of the radially disposed, opposed abutment surfaces and the axially spaced abutment surface, when the components are disposed in mating relation, and apparatus for selectively displacing the locking member into the extended and retracted positions.

Assembly for coupling an implement to an operating arm of a machine in

An assembly for coupling an implement to an operating arm of a machine comprising a first component fixedly mountable on the implement, a second component connectable to the operating arm, one of the components having a slot in a side and bottom thereof, disposed substantially radially relative to a given axis, and the other of the components having a section receivable into the slot to position the components in coupling relation, the components having engageable surfaces permitting angular displacement and precluding axial displacement relative to the given axis when the components are disposed in coupling relation and retaining means disposable in abutting relation relative to the components when disposed in coupled relation for precluding angular displacement between the components relative to the axis.

Coupler assembly

A system for detachably coupling an attachment to a prime mover provided with a mounting means and an actuating means generally comprising a female device mountable on the attachment and a collapsible male assembly mountable on the mounting means of the prime mover, cooperatively engageable with the female device, the male assembly being operatively connectible to the actuating means and movable thereby between a collapsed, inoperative condition and an extended, operative condition operatively engageable with the female device in coupling relation therewith when the male assembly is positioned adjacent the female device in registry therewith, and means mounted on the male assembly for selectively locking the male assembly in the extended, operative condition.
