[Class 103 (i)] A brake for use in effecting speed changes in change speed automobile transmissions and for other purposes comprises a cone ring adapted to be given a part rotation movement and thereby to be moved axially to wedge between a rotating member to be braked and a fixed surrounding ring or band. Cone rings A, B are disposed between a fixed ring F and a cone ring E splined at H to the rotating member G to be braked. Balls 5 are arranged between the rings A, B and F in inclined races 6. Each ring A, B has a cam follower A, engaging one of a pair of cams C\ C2, the cam C<SP>1</SP> being fixed to the shaft 3 and the cam C<SP>2</SP> being loose on the shaft but having a pin 1 that enters a slot 2 in the cam C<SP>1</SP>. The followers of both cams are normally in the raised position shown. When the shaft 3 is turned clockwise, the ring A is permitted by the cam C' to turn to a limited extent under the action of a spring 7, in the same 'direction as that of the member G and the ring A is thus moved to the right by its ball race so that the ring E is gripped by the rings A, B and the member G is braked. Upon further rotation of the shaft 3 the ring B is permitted to turn by the cam C<SP>2</SP> and is tgus moved to the right to release the brake after further rotation of the shaft 3 both of the rings A, B are turned in the reverse direction and are thus moved to the left to the original positions shown in Fig. 2. If the cam shaft movement is now reversed, the cam C<SP>1</SP> is at first only turned by reason of the pin and slot 1, 2, thus reapplying the brake. Further reverse movement of the cam shaft successively releases the brake and returns the rings A, B to the neutral position shown in Fig. 2.
