Abstract

324,866. Hammond, R. J., Oswald, A. R.. J., and Sharp, A. B. April 23, 1929. Disc apparatus.-In a valve seat grinding machine the grinding wheel is driven through a flexible and resilient coupling. The grinding wheel 6 is attached to a rod 1, which engages the valve rod bush, by a member 7. A driven member 13 is connected to the member 7 by a spring 15. A ball and socket joint on the ends of the members 7. 13 transmits the drive. The spring is a forced fit on the members 7, 13 and holds the parts forming the ball and socket joint in contact.
