Abstract

425,521. Sight - testing apparatus. SIMPKINS, R. B., 13, Holly Road, Edgbaston, Birmingham. Sept. 6, 1933, No. 20737/34. Divided out of 425,474. [Class 97 (i)] [See also Group VI] Apparatus for testing the ability of the eye to follow straight-line and circular movements comprises a disc 11 bearing a central focusing spot and carried on a slide 11<c> mounted on an arcuate bar 10. The bar is secured in a diametral position on a disc 15 rotatably mounted by a spindle 15b on a handle 8<a>. A bar 13 pivoted behind the disc 11 is used to move the disc along the bar or to rotate the disc 15, either of these movements being prevented if desired by the provision of a locking screw 12 and a lock-nut 17. In a modification the disc 15 is rotatably mounted in an annular mounting carrying the handle 8<a> and the bar 10 may be mounted behind the disc 15, which is provided with a diametral slot through which the support for the disc 11 protrudes. In this construction the bar 13 may be replaced by a disc loosely mounted on the support for the disc 11. In a further modification, the disc 15 is dispensed with, the bar 10 being mounted on a ring rotatable in an annular mounting. Specification 425,474 is referred to.
