Abstract

830,929. Copy-milling. HAYES ENGINEERS (LEEDS) Ltd. Aug. 30, 1957 [Sept. 10, 1956], No. 27599/56. Class 83 (3). An hydraulic control valve unit comprises a tracer mounting element 6 bearing on at least one valve 21, and having an annular flange 10 interposed between ball bearings 13. Movement of the element is limited by a screwed collar 14 adjusted by graduated means 17. The top of the element is biased by spring means 22 against the valve 21, there being a similar valve at right angles thereto, also with a biasing spring. The unit is manually operated, and may have a hand control 25 connected to the upper or lower end of the element 6. The stylus is of the same diameter as the tool.
