Abstract
Abstract A gathering blade is mounted on a vehicle which carries a front end loading bucket, so that material can be gathered by the blade and pulled onto the bucket. The gathering blade is mounted on the ends of a pair of arms which are slidable longitudinally in a pair of guides, one on either side of the vehicle, and preferably in the planes of the control and operating arms of the bucket. The blade can be lifted up under the arms, which can then be retracted by means of hydraulic and pistons. The guides are rotatable about an axis attached to the vehicle, and are supported by pistons and cylinders from the operating arms, so that the bucket has full freedom of movement in an upwardly direction, and the blade does not obstruct the view of the operator.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
227 words
A gathering blade apparatus for attachment to a vehicle having an earth-moving bucket supported by longitudinal operating arms, of conventional design, comprising; (a) a gathering blade comprising a blade positioned transverse to the longitudinal axis of the vehicle, by hinge means near its top edge, to a pair of spaced-apart, parallel blade support arms; means to rotate the plane of said gathering blade a selected angle from forward of the vertical, to substantially horizontal, under said blade support arms, the transverse length of said blade being less than the transverse length of said bucket; (b) a pair of guide means supported by horizontal hinge means to said vehicle, and extending parallel to the longitudinal axis of said vehicle, said guide means adapted to receive and to longitudinally guide said blade support arms; (c) a pair of hydraulic cylinders and pistons attached to said guide means, and piston rod means, attached at their outer ends to the outer ends of said blade support arms; whereby operation of said piston serves to move said support arms and said blade between positions forwardly or rearwardly, with respect to said bucket; (d) means to rotate said guide means about said horizontal hinge means with respect to said bucket operating arms; whereby said blade can be raised and lowered independently; and wherein, said blade will be raised whenever said bucket is raised.

A gathering blade apparatus for attachment to a vehicle having an earth-moving bucket supported by longitudinal operating arms, of conventional design, comprising; (a) a gathering blade comprising a blade positioned transverse to the longitudinal axis of the vehicle, by hinge means near its top edge, to a pair of spaced-apart, parallel blade support arms; means to rotate the plane of said gathering blade a selected angle from forward of the vertical, to substantially horizontal, under said blade support arms, the transverse length of said blade being less than the transverse length of said bucket; (b) a pair of guide means supported by horizontal hinge means to said vehicle, and extending parallel to the longitudinal axis of said vehicle, said guide means adapted to receive and to longitudinally guide said blade support arms; (c) a pair of hydraulic cylinders and pistons attached to said guide means, and piston rod means, attached at their outer ends to the outer ends of said blade support arms; whereby operation of said piston serves to move said support arms and said blade between positions forwardly or rearwardly, with respect to said bucket; (d) means to rotate said guide means about said horizontal hinge means with respect to said bucket operating arms; whereby said blade can be raised and lowered independently; and wherein, said blade will be raised whenever said bucket is raised.
Claim 3
Dependent Claim
32 words
The apparatus as in claim 1 in which said means to rotate said guide means comprises cylinder and piston means connected between said guide means and said operating arm of said bucket.
