Abstract
5412. Peake, W. March 4. Levels.-Relates to a coarse and fine adjustment for levels and clinometers. The base a<2> has hinged to it an arm a within which can move an arm b, also hinged at a<1> and carrying the level-tube. The end of the arm a can move over an arc G<2> which is graduated in degrees by the holes G<4> and has attached to it a rack G<5>, the spaces in which can be engaged by a detent G' on the arm a, operated by the lever G<3>. To set the arm a to any given degree, the pin I is inserted in the corresponding hole, the arm is moved up until the stop J thereon abuts against the pin, and the lever G<3> is turned to engage the detent G<1> with the rack G<5>. The setting for minutes and seconds is obtained by rotating the arm b by means of the screw L having a slot M in which engages a projection N on the arm. The screw L is operated by a thumb-piece d<2> and carries a dial d, graduated in minutes up to 15 and having a tooth f to engage the teeth of the quarter-degree dial e. The projection N rests on a bridge 0 which can be adjusted to correct its distance from the hinge a<1>. To secure fine initial adjustment, the projection N is hinged at V and can be moved to a limited extent by means of the screws p, p'. Other means may be employed to adjust the arm b; for example it may be formed as a slide, one end of which can be moved horizontally by means of a nut and screw, while the other end moves along an inclined path.
