Abstract:
An electric handheld broadcast spreader with pattern and speed controlling baffled skirt detachably attaches to a conventional spreader mechanism to disperse particles in a controlled, directional manner within a proximal coverage area with two hands. A broadcasting/dispersing skirt receives particulate material from a conventional spreader. The inner volume of broadcasting/dispersing skirt comprises upper layer baffles, with upper gaps forming between each upper layer baffle; lower layer baffles, offset from the upper layer baffles, with lower gaps forming between each lower layer baffle; and multiple vertical deflector vanes disposed perpendicular to lower layer baffles. Discharged particulate material strikes the surface of the baffles, before passing through gaps. The particulate material traveling in a lateral direction strikes the deflector vanes and outlet edge of broadcasting/dispersing skirt. This controls velocity and direction of dispersed particulate material, causing particulate material to be confined within a close pattern coverage area on ground surface.

Claim (Index 20):
A particulate material broadcasting/dispersing skirt and baffle spreader, the spreader consisting of:\n a storage hopper defined by a receiving inner volume and forming an inlet aperture sized and dimensioned to enable passage of a particulate material into the receiving inner volume, the storage hopper having an inverted pyramidal shape; a lid removably covering inlet aperture of storage hopper; a pair of handles joined with the conventional spreader; a broadcasting/dispersing skirt adjacent to, and in communication with the conventional spreader, the broadcasting/dispersing skirt being defined by a dispersing inner volume having an upper region and a lower region, the lower region terminating at an outlet edge forming an outlet aperture sized and dimensioned to enable passage of the particulate material, the broadcasting/dispersing skirt having a pyramidal shape; a broadcasting mechanism operatively attached, and in communication with the storage hopper and the broadcasting/dispersing skirt; a velocity switch operatively connected to the conventional spreader, the velocity switch regulating discharge velocity of the particulate material; a volume dial to control the amount of particulate material that is emitted from the storage hopper into the broadcasting/dispersing skirt; a power switch; multiple elongated upper layer baffles traversing the upper region of the broadcasting/dispersing skirt, the upper layer baffles being disposed coplanar to each other, the upper layer baffles forming an upper gap between each upper layer baffle, the upper layer baffles being defined by a V-shape having an upper peak and an upper surface area; multiple elongated lower layer baffles traversing the lower region of the broadcasting/dispersing skirt, the lower layer baffles being disposed coplanar to each other, the lower layer baffles further being disposed in parallel, offset relationship from the upper layer baffles, the lower layer baffles forming a lower gap between each lower layer baffle, the lower layer baffles being defined by a V-shape having a lower peak and a lower surface area; multiple vertical deflector vanes disposed in a spaced-apart relationship from the lower layer baffles, the deflector vanes being oriented perpendicular to the lower layer baffles; whereby the particulate material introduced into the dispersing inner volume of the broadcasting/dispersing skirt strikes the upper peak and the upper surface area of the upper layer baffles, and further, the particulate material striking the upper peak and the upper surface area of the upper layer baffles passes through the upper gap; whereby the particulate material passing through the upper gap strikes the lower peak and a lower surface area of the lower layer baffles, and further, the particulate material striking the lower peak and the lower surface area of the lower layer baffles passes through the lower gap; whereby at least a portion of the particulate material passing through the lower gap strikes the vertical deflector vanes and the outlet edge of the broadcasting/dispersing skirt; whereby the particulate material striking the deflector vanes and the outlet edge disperses through the outlet aperture in a close pattern coverage area; wherein the upper and lower layer baffles are angled between about 60\u00b0 and 110\u00b0; wherein the width of the upper and lower layer baffles is about 0.75 inches to 1.5 inches; and wherein the spacing between each upper layer baffle and each lower level baffle is about 75 percent of the width of the baffle.
