Abstract

418,865. Time-pieces. HARWOOD, J., 120, Pinner Road, Harrow, Middlesex. Oct. 23, 1933, No. 29295. [Class 139.] Winding-apparatus.-In a time-piece, which is self-wound by an oscillating weight, the weight oscillates in or parallel to a vertical plane through the axis of the indicating hands and is combined with a toothless winding mechanism. Rigid with the winding arbor A<1> of the mainspring A is a disc B, the edge of which coacts with two studs G, G<1> and a lever I on a trefoil plate E. Lever I is connected by link O to an arm 0 <1> rigid with the weight W which oscillates about pivot R against spring X. When the link O is raised, the nose of lever I binds on the edge of disc B and the latter is moved counter-clockwise, Fig. 2, with plate E to wind the mainspring. A similar trefoil plate D with pins F, F<1> and lever H prevents retrograde movement of disc B in a clockwise direction. V, V<1> are buffer springs. To prevent overwinding the link O may be made in two relatively sliding parts which are joined together by an S-spring slightly weaker than the fully wound mainspring. A mark on the weight may be visible through a hole in the dial to indicate whether the weight is oscillating freely. The movement of the timepiece, or the timepiece as a whole, may be mounted for oscillation so as to function as the winding weight.
