Shows the gears beneath theslot-plate, each with its four guidefingers that mesh to carry the bobbinslide into the opposite slot at eachquarter revolution. 399. WIRE-COVERING MACHINE. G is the wire reel fromwhich the wire is drawn through the machine by the geared rollers E, E, and wound upon adrum at H. A rub-ber ribbon is wrappedupon the wire throughthe guides and eye at A. The spool C de-livers the wrappingribbon through theeyes of the revolvingyoke J, J. The gears B, B drive the shaftA^ and worm a, giv-ing motion to thedrawing rolls E, E,and the winding drum H, through the gears N, M. b is the driving belt. The chainand gear below the bed of the machine are for change motion to thewire feed by a train of spur and bevel 168 ELECTRIC POWER AND DEVICES. 400. SHUNT-WOUND DYNAMO. The brushes B, B are con-nected to the main Hnes, M, M, supplying the outside circuit. The field magnet coils ^5 s are connectedin shunt across the armature at thebrushes B, B. The field coils are offine wire and many turns, with a re-sistance of many times that of thearmature, in which is interposed theresistance box R. 401. SHUNT DYNAMOS con-nected in series. The shunt winding isconnected across both dynamos andthe other end of the winding to theopposite poles in the armature brushes. 402. SHORT AND LONGSHUNT. Compound dynamo wind-ing. Shows the two ways of makingthe terminal connections of the wind-i
