The inner half of the blade is then forced fromthe clip by positive action and is drawn sharply to the outerhalf by the tension springs. This results in an extremelyquick break and a wide gap, over which an arc cannot of this type are made for both single and doublethrow, with or without bases, and with either front or backconnections. AN AUTOMATIC CAR FENDER. The accompanying cut represents an automatic car fenderdesigned by Obe. Cullison. It is attached to the wheeltruck, is simple in construction, does not extend far in frontof the car and is automatic in action. When striking anobject the two coil springs are released and the fender shootsout about 3 ft., or this result ma}- be effected by themotorman striking a foot lever attachment. A contactroller is at the front of the fender but there is little oscilla-tion as the fender is attached to the truck. The fender canreadily be changed from one end to the other of the car. Henry G.
