<p>ELECTRIC MOTOR BRUSH HOLDER The disclosure concerns a brush holder 31 for an electric motor comprising a tube member 31 which is provided with an opening at one end through which an electrode 30 slides. A compression spring 35 is held between the electrode and an abutment at the rear end of the tube. At least a pair of opposite side walls 44, 45 of the tube are generally cylindrically curved to define the area in which the compression spring is contained. The cylindrically curved side walls are slit at 50,51 at a point spaced from but adjacent the open end from which the electrode projects leaving a pair of short axial length, flat parallel walls 52, 53 adjacent the open end. The rear edges of the short walls extend across the curved tube at the front of the spring. The rear edges of the short walls furnish a stop for the spring and prevent it from being ejected from the tube. The electrode is attached to the spring at 36.</p> |
