Show the roan type of gathering locomotive WRITTEN FOR THE MINING REVIEW an improved electric mining locomotive of the gathering type in which a single powerful motor performs the functions of both propulsion and operation of the gathering reel has been brought out by the westinghouse electric manufacturing company and the baldwin locomotive works under the patents of an invention of mr J al roan mr roan who is general manager of the clinchfield Clinch field coal corporation po ration is a practical mine operator and on this account the gathering locomotive of his invention may be relied upon to meet exactly the requirements by the practical mining men in the roan gathering locomotive the sin the working face to the butt heading on which the locomotive stands the rope is paid out and attached to the cars the main driving motor is then from the axle and connected to the reel which winds up the rope drawing the car toward the locomotive which stands with its brakes set on the heading track the provision for propelling the locomotive at the same time the reel is in operation enables the cars to be swung on to the heading without sawing the rope on the rib at the room neck in service many applications have suggested themselves for the combined and hauling in actions action secured from the motor derailed cars may be easily re 4 V pr k lk I 1 AN 4 4 14 41 at W gle motor used to drive the wheels is arranged to be detached and connected to the wire rope gathering reel the wheels or the reel may thus he be operated either independently or simultaneously winding up the rope while the locomotive is in motion the arrangement described secures advantages of flexibility compactness and reduced amount and cost of electrical apparatus attained in no other type the provision of one powerful motor to perform the duties of both gathering and driving motors cuts in half motor and controller ex pense at the same time lime making the total power of the traction motor available for the gathering reel when loaded cars are to be hauled from placed on the track timbers and rails recovered from under falls of rock rails loaded on cars and in fact the reel can be used for any kind of general hoisting work the motor transmits its power through a single spur gear directly to one axle the two axles are connected together by side rods spaced 90 degrees apart securing increased effort beyond that of any single motor or two motor locomotive As shown the wheel is extremely short although the wheels are of full size and the maximum amount of service is secured by the spring suspension of the frame and motor the locomotive frame is made up of steel angles and plates giving maximum strength for a given weight |
