ABSTRACT:
The tool of the present invention is comprised of a scoop with a short upright stem which is connected to a threaded broom handle of any length thru a multi-positional, self-locking, rotary acting articulated joint. Opposing surfaces of both members of the joint are constructed with raised ridges designed and constructed such that when these surfaces are placed proximate one another, the ridges exactly interlock, and, when secured with a nut, bolt, washers and compression spring affixed thru a hole bored thru the center of the surfaces, the interlocking ridges will tend to hold the joint, and hence the scoop, in any of a number of positions as selected by the user. If desired the nut can be locked to overcome the compression spring thus securing the joint against forceable movement establishing a firm, shovel-like effect. The stem of the scoop is secured to the joint by means of a pin inserted at right angles thru the stem and thru slots cut into the joint member, constructed so as to provide for lateral movement of the scoop around the vertical aspect of the stem. This construction provides for necessary lateral movement of the scoop as it is negotiated thru the gutter by the operator. The operator by means of a long broom handle may thus remotely control the scoop thru the gutter from a convenient and standing position on the roof or from a ladder.
