We show in the accompanying illustration an improve-ment in trolley harps. The manufacturers state that thisharp has been adopted by the Rapid Railway Company, theMt. Clemens Fast Line, and the Sandwich, Windsor & Am-herstburg Railway after a trial of 30 days. The former com-pany states that it was used on one of the fast cars havingtwo 75-h. p. motors geared to 50 miles per hour, and that itran 7,652 miles with one oiling and showed no wear of anyparts. The latter company states that after 30 days therewas enough oil left for another 30 days, that there was agreat saving of oil and labor, and no leakage on top of SELF-OILING TROLLEY HARP. It would seem from this that this trolley harp would supplya long felt want. The company also states that it believes, with oil of properconsistency, and with axles ^4 in. to % in. in diameter, theywill run 60 days with one oiling; it considers the axle atpresent used, yi in. in diameter for a 6-in. wheel, too smallfor the best results. It is prepared to make quotations onharp, wheels and bushings, complete or separately, also tosupply harps with larger axles and bushings. Referring .to tlie cut, each side of harp holds one ounce ofoil. C is the main reservoir; A the auxiliary reservoir; D,filler plug; E, feed to axle; H, felt to prevent rapid flow ofoil; B, passageway through which oil passes to auxiliary res-ervoir when trolley is reversed at the end of a trip. Afterlong use the harp can be blown out with steam and cleaned,by simply taking apart and blowing a jet of steam throughthe filler plug, D. Any further information will be cheer
