    摘要： Commutators of armatures for electric motors or other dynamo-electric machines are finished by subjecting them to inspection and turning operations. The first inspection operation determines the minimum amount of material that can be cut while producing a high quality armature. This determination may indicate that no formal turning is required, only finishing. The turning operation, if applicable, cuts the commutator to a substantially cylindrical shape which is substantially concentric with the axis of rotation of the armature. The finishing operation, which may be performed by the same mechanism as the turning operation, imparts a desired axial roughness to the cylindrical commutator surface. The commutators may be inspected after the turning and finishing operations to generate data useful for such purposes as automatically modifying the turning and finishing operations performed on subsequent commutators.

    摘要： An electrical machine in which power is supplied to the rotor via brushes and sliprings having an improved brush-dust suction apparatus, including brush supports and ring-shaped collecting chambers which are penetrated by brush bolts. The suction openings of these collecting chambers circumscribe the slipring in a ring pattern. Each collecting chamber is connected by thick-walled glass cylinders to a common collecting chamber, which is connected to a negative pressure source, when the air and the brush dust entrained in the air is conveyed to an exterior chamber. The brush supports are fastened by insulators to the collecting chamber and are mutually reinforced by insulator bolts.

    摘要： A grindstone or like block of abrasive material is affixed at the lower end of a first support rod slidably received in a vertical sleeve. A second support rod coupled to the sleeve at a right angle thereto is also slidably received in a hollow offset arm at the upper end of an upright standard. An electromagnet is clamped to the standard for releasably mounting the commutator grinder on a desired commutator machine. The commutator grinder is further equipped with an infeed mechanism and a traverse feed mechanism which enable the grindstone or the like to be fed toward and in the traverse direction of the work. The infeed mechanism comprises a handle, worm gearing, and a feed rod screwthreadedly received in a hollow formed axially of the first support rod, such that the rotation imparted from the handle to the feed rod via the worm gearing is translated into the up-anddown motion of the first support rod relative to the sleeve. The traverse feed mechanism also comprises a handle and a feed rod screw-threadedly received in a hollow formed axially of the second support rod, the rotation of the second mentioned feed rod being likewise translated into the back-and-forth motion of the second support rod relative to the offset arm.
