The sleet wheel and sleet cuttershould be of particular interest in- view of the operating dif-ficulties brought about by the present severe winter. Thiscompany also manufactures several types of harps, of whichthe type B illustrated is perhaps the most interesting. Thepeculiarity of this harp is that its top flanges project beyondthe wheel so that the side wear is taken by the harp flanges,. Sleet Wheel Projecting Flange Harp and not by the wheel. Although many assert that rigid ironflanges of this kind wear out the overhead line very rapidly,the manufacturer of this harp states that these opinions havenot been borne out in practice. For instance, this harp is re-ported as having been used with a 6-in. wheel on a line about13 miles long for over nine months, yet during that period thewear on the harp flanges has been only % in. During the sametime even the overhead special work has shown no appreciablewear. The protection afforded by this harp has made it pos-sible to secure a wheel life of 12,000 miles in nine monthsservice near Cleveland. This company also makes ball-bearingtrolley bases and other fittings for overhead current-collectingdevices.
