Abstract

13,876. Hollick, A. J. June 8. Levelling - heads. - In levelling-heads of the kind comprising two relatively rotatable wedgeshaped bodies 1, 2 having their inclined faces in contact, the bodies are secured together by one or more metal strips 5 fitting into grooves 4 in the inclined faces. Similar grooves and strips are provided to secure the levelling-head to the stand 7 and to the instrument-carrying table 8. The strips 5 generally have a curvature different from that of the grooves; but the curvatures may be the same, in which case the strips may be replaced by a series of balls. In a modification, a series of studs or guides arranged circularly on one face engages with a groove on the other.
