Electrical news and engineering . device with no gears, cams or belts, and requires no settingup for a job. The operation of the machine is about the THE ELECTRICAL NEWS same as that of a plain taping machine, but is said to beeasier. The feed can be varied to obtain a variety of lapsand the pull of the tape is taken oft the operator to such anextent, it is claimed,—that the coil can almost be allowedto lie in the operators hands while taping Vertical Wire Clamp The problem of attaching a vertical wire ti> a commonline insulator and keeping the latter in correct position, isclaimed by the States Company, 19 New Park Ave., Hart-ford, Conn., to have been solved with their Thesco device fits standard insulators and it is claimed to cut. the energy losses of distribution by keeping down a leakagefrom the conductor to the insulator pin. The clamps aremade of malleable iron, galvanized by the hot dipping pro-cess. Both halves are alike and interchangeable. The manu-facturers claim that these clamps will not break the glass,as there is but one bolt and the covering of the conductor re-ceives the pressure that may result from unequal expansion. Direct-Current Lightning ArresterA direct current electrolytic lightning arrester, for volt-age applications up to 3,800 volts has been recently devel-oped by the Westinghouse Electric & Manufacturing Com-pany. The device contains one to twelve cells and is de-signed for car or station use on railway, power and lightingcircuits. The construction embodies two aluminum platesimmersed in a suitable inorganic electrolyte and supportedfrom a porcelain cover clamped by a zinc ring to a glass jar
