TITLE Combination Clutch-Brake ABSTRACT OF THE DISCLOSURE A combination clutch-brake is shown according to the present invention including a housing having an output shaft rotatably mounted therein. A first hub having a first friction disc with a friction lining thereon and connected thereto is slideably mounted on the output shaft and rotatable therewith. A single annular piston is slideably mounted in a cylinder formed in the housing with a bearing interposed bet- ween the annular piston and the first hub allowing the hub to rotate radially within the annular piston. An annular spring housing having an annular backing portion with a friction lining connected thereto is fixedly mounted within and carried by the housing axially with respect to the piston. The spring housing has a series of spaced springs mounted thereon in urging contact with the piston whereby the friction lining of the spring housing backing portion contacts the first friction disc for braking of the output shaft when there is no fluid pressure in the cylinder. A second hub for connection with an input shaft and having a second friction disc thereon is rota tably mounted within the housing and engageable with a friction lining on the first friction disc when fluid pressure is introduced into the cylinder to thereby withdraw the first friction disc from the friction lining of the annular backing of the spring housing thereby debraking and clutching in the output shaft.
