Abstract

6287. Reading, H. C., [trading as Reading & Co., H. C.]. March 21. Clutches.-Relates to band clutches for motorvehicles &c. actuated by electromagnetically-operated plate clutches. A plate D is carried on pins h<1> on a loose sleeve H, a projection on which forms a pivot for one end of a band F, the other end of which is pivoted on the driven part e of the device. When the electro-magnet A is energized, it attracts the plate D into frictional contact with it, and the sleeve H is rotated against the action of springs f<3>, f<4> so that the band F is expanded against the flange g on the magnet A. For use with an alternating current, the disk A may be built up of a series of concentric channels contained within a recess and containing the wire, the inner and outer faces of the recess forming the poles. The channels may be insulated by brazing metal. In the case of direct current, the release of the armature may be effected by reversal of the current or by a suitable winding. The clutches may be used in variable-speed gearing.
