Abstract

20,928. Larrad, J. L. Sept. 20. Levels; clinometers.-A base-plate A, Fig. 1, has a plane under-surface in' which is cut a groove A<1> with plane sides so that it may be placed upon a shaft B or other worked surface, to which it is clamped by means of a screwed hook N', a chain N attached to one end of a slotted bar M, and a nut N<2>. Mounted so as to move in a plane normal to the base-plate is an arm D, which can be clamped by means of a screw and nut E. Adjustably mounted on the arm D is an arm F to which is attached by means of a split holder H a disk K, which is graduated in degrees and upon the spindle of which is rotatably mounted a spirit-level L and pointer L<2>. To indicate the position of the centre of the tool relatively to the shaft, a pin P, Fig. 4, is placed in the centre line of the base-plate and is kept pressed against the shaft by the spring P<1>. In a modification shown in Fig. 5, the arm D is mounted on a plate C' which is pivoted at C<2> and can be clamped by the nut C<6>. The instrument may be used for measuring the angular movement of a shaft, for setting cranks at proper angles to shafts, for adjusting vertical shafts, and for like purposes.
