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.

A tool for removing debris from a rain gutter, said tool comprising: (a) a rigid and generally U-shaped scoop having an open end, a closed end, side walls and an integral bottom; (b) an elongate stem situated at said closed end of said scoop constructed at right angles to the longitudinal axis of said scoop, the axis of said stem considered to be in a vertical position when said scoop is inserted into a gutter cavity; (c) a rotary acting, multi-positional self-locking articulated joint mounted on the distal end of said elongate stem, said joint consisting of first and second joint members and constructed with flat proximal and tubular distal ends, having; a plurality of raised ridges radially arranged about a a central locus on said proximal ends of said first and second joint members constructed to exactly interlock when the proximate ends of said first and second joint members are juxtaposed; said juxtaposed joint members affixed with a properly adjusted bolt, nut and compression spring to provide an inwardly directed force sufficient to prevent movement of the joint until overcome by an outside force of sufficient magnitude to move the joint to a new position; said tubular distal end of said first joint member constructed with a receptacle to accept said distal end of said elongate stem; said tubular distal end of second joint member constructed with a receptacle to receive an elongate handle; (d) said first joint member affixed to said distal end of said elongate stem by a pin and slot arrangement considered to define the range of lateral movement of said scoop around said axis of said stem, consisting of two elongated slots constructed thru the sides of said receptacle of said first joint member and situated exactly opposite each other, said slots positioned perpendicular to the axis of said receptacle, through which a pin of appropriate length is inserted thru one slot situated on one side of said receptacle of said first joint member then entirely thru a properly positioned bored hole in the properly inserted said elongate stem, after which said pin shall pass unimpended thru the second slot situated exactly opposite the first slot of said receptacle, whereupon said pin is considered in its final resting position, said pin and slot arrangement providing a means to restrict the range of lateral movement of said scoop around the axis of said elongate stem.
