Abstract: The said industrial design consists of a portable electric grinder having a grinder disk section, a main body section and a handle section; the grinder disk section has a circular disk having flat upper and lower surfaces, a generally semi-circular flat to cover portion spaced above and extending outwardly slightly beyond the upper surface of the circular disk, and an arcuate skirt extending generally at right angles to and downwadly from the periphery of the top cover portion; the top cover portion merges into the arcuate skirt through a short beveled surface and the lower edge of the arcuate skirt is beveled inwards; a central portion of the top cover portion curves upwardly a short distance to an annular collar portion of the main body section; the top cover portion extends rearwardly and is situated adjacent a lower surface of a forward end of a right end section of the main body section; the main body section has a generally cylindrical right end section which merges into an irregular shaped left end section; the sides of the right end section have generally identical rearwardly extending first bullet-like areas each having a flat front end, straight side edges, and a rounded rear end situated close to the end of the right end section, the first bullet-like areas have a central circular recessed area situated close to the rounded end thereof; the right end section has a series of generally identical longitudinally extending parallel slots having rounded ends situated on either side of the rounded ends of the first bullet-like areas and also situated between the rounded ends of the first bullet-like areas and the right end of the main body section; the forward portion of the right end section has four spaced-apart generally identical second bullet-like areas which extend longitudinally rearwards from adjacent the forward edge of the left end of the right end section; the second bullet-like areas have smoothly curved bullet-like protuberances which generally follow the contour of the second bullet-like areas in plan view and which have laterally extending slots on the curved outer surface thereof; the irregular shaped left end section of the main body section has downwardly and outwardly flared side and front surfaces and a raised top rear laterally extending portion having a flat rectangular top surface, flat end surfaces, and flat short rectangular side surfaces which extend downwards and outwardly therefrom; the flat rectangular top surface has longitudinally extending protuberances having straight parallel side edges and rounded ends; the raised top rear portion merges into a rearwardly facing generally U-shaped upper portion having a flat top surface, beveled sides, and a circular depression in the top surface thereof; the outwardly flared side surfaces of the irregular shaped left end section of the main body section has two pair of longitudinal slots having beveled edges extending along the sides thereof, the lower of each pair of slots narrowing from front the rear; a generally vertically extending slot is situated between the forward ends of the longitudinal slots on the front flared surface of the irregular shaped left end section; the left end surface of the left end section is curved and has rounded corners in plan view which merge into side surface depressions having scalloped side surfaces; the side surfaces of the irregular shaped left end section of the maid body section have slightly raised generally flat areas having downwardly and forwardly angled rear end edges, rounded forward edges, and a circular depression therein; the lower surface of the irregular shaped left end section has a front end recessed area having an angled rear surface; the lower surface of the recessed area merges into the upper end of the annular collar portion of the main body section; the handle section has a curved upper grip portion which is generally rectangular in plan view with rounded corners and has parallel rows of spaced-apart small generally identical circular areas thereon; the lower side surfaces of the handle section have parallel rows of spaced-apart small generally identical circular areas thereon which conform to the rows of small circular areas on the upper grip portion; the handle section has an enlarged end portion and a lower surface of the forward end portion of the handle section has a downwardly-extending trigger-like portion having a flat lower surface extending the length thereof; the upper surface of the forward end of the handle section merges smoothly into a slightly raised area of the upper portion of the generally cylindrical right end section of the main body section and the forward sides of the handle section flare outwards and merge into the adjacent sides of the cylindrical right end section of the main body section; the flared sides have a series of short longitudinally extending slots situated therein which have rounded ends and which decrease in length on either side of a central slot; the slots in the flared portions of the handle section are generally aligned with the slots in the right end section of the main body section.Representations of the design are shown in the figures wherein:Fig. 1 is a perspective view of the design of a portable electric grinder;Fig. 2 is a front elevation view thereof;Fig. 3 is a rear elevation view thereof;Fig. 4 is a left side elevation view thereof;Fig. 5 is a right side elevation view thereof;Fig. 6 is a top plan view thereof;
