Combined Skidding and Loading Machine—The Russel Wheel & Foundry Company, Detroit. There are three skidding drums, 30-inch diameter, 30-inch face, two of which only are in constant use, the third being only used in case of a broken line to avoid delay while splicing. This engine i6 also equipped with two drums for tightening the guy lines—and drum for a car spot- ting line. On the front end of the machine is a skeleton steel tower from which is suspended a vertically hinged jib, or triangle, from which the skid- ding sheaves are hung at the outer end, on each side of the jib, just over the skidding sheaves, is a guy line sheave. The two guy lines are made fast, one on each side of the machine, to any convenient stump or tree entirely without regard to their relation to each other, the lead of the lines may be backward approximately to an angle of 45 degrees from the centre line of the machine. The guy lines lead through the sheaves on the end of the hinged jib, through sheaves on the tower to two friction driven power operated drums on the skidding engine. The connection of the hinged jib at its upper end to the tower is not rigid, being provided with a spring ar- rangement similar to the draft rigging on a car. The company claim that by this arrangement the following advantages are secured: first, there can be no interference between the skidding lines and the guy lines; second, the guy lines cannot possibly interfere with the loading boom; third, all strains due to skidding are absorbed by the guy lines: fourth, all shocks are softened by the spring attachment of the jib; fifth, an operator standing on the deck of the machine watching the hinged jib can bring it into an exactly central position with an equal strain on each guy line; sixth, should one guy line stretch they can be equalized without any delay to the skidding or loadi
