Abstract

800,413. Grinding; abrasive tools. LEAVITT MACHINE CO. Dec. 15, 1955 [May 13, 1955], No. 36034/55. Class 60. A rotary tool for a gate valve grinding machine comprises a support having legs 16 with parallel flat surfaces 18, 19 and outwardly convergent side walls 22, 23, grooves 35 are provided between the inner ends of adjacent legs. Each leg 16 has on its outer flat surface 19 a resilient backing element 30, and carries a tubular member of abrasive-coated flexible material. When the operative portion 67 of the tubular member is worn, the member is reversed. The tool is carried by a mount 11, being held between flange 26 and spring washer 28. The mount 11 is supported by a member 144 on threaded portion 142 of a shaft 112, member 144 being retained by a screw 148 entering a threaded opening 150 in the shaft. The mount 11 is driven by the member 144 through a spring element 152, slippage taking place when there is an overload. The shaft 112 is keyed at 128 to the flange 108 of a sprocket wheel 106 driven by a chain 160 from a sprocket wheel 107.
