Abstract
13,448. Hopkinson, B., and Thring, L. G. P. June 12. Optical pointers.-The torsion in a rotating shaft is measured by imparting deviation to a beam of light. Fig. 2 shows one form of dynamometer, in which a sleeve B and collar C are attached to the shaft A by screws at points B<1>, C'. The collar may form, as shown, a bearing for the sleeve. The sleeve C carries a plane or concave mirror D rotatable about an axis D<1> and provided with an arm D' which engages by the frictionless ball D' and spring D<4> with an arm B' integral with the sleeve B. A lamp E, slidable on a scale E', is adjusted. so that its filament is seen on the cross-hair of the telescope F, after reflection from the mirror. When the shaft is transmitting power, the arm B<2> turns the mirror through an angle depending on the torsion between the points B<1>, C<1>. The lamp is again adjusted until the image is seen on the cross-hair of the telescope, and the torsion read on the scale. Fig. 10 shows an end view of a modified device. In this case, two mirrors D are shown, although only one is necessary. The bearing of the sleeve B in the collar C is in this case formed by two setscrews C<3> and two rollers C<4>, one of which may be controlled by a spring C<5>, so that relative movements, other than rotary, of the members B, C are not transmitted to the mirror. In the form shown in Figs. 11 and 13, the collar C has two flanges C<6>, the mirror carrier being held between them by a a bolt C<9>. A similar flange B<3> is attached to the member B and carries the mirror-deflecting arm B'. Projections C<7> on the member C engage with extended portions B<4> of the member B, and the two members are yieldingly-connected by springs C<8>. The bearing between, the members B, 0 is in this case formed by two set-screws G<1> and a spring- controlled bearing G<2>. A method of mounting the mirror is described.
