Abstract
426,217. Testing eggs. DAVIES, T., Brynog Lodge, Felinfach, Lampeter, Cardiganshire. Oct. 24, 1933, No. 29382. [Class 28 (ii)] A portable egg-tester comprises a reflector a, a base b external thereto, a lamp d on the axis of the reflector and an egg support c at the mouth of the reflector. The support c may be an apertured plate, or a glass dish which may be formed with depressions or seatings for the eggs, the spaces between the depressions being rendered opaque. A screen g may be provided to prevent external light from reaching the eggs, the eggs being viewed through the opening g'. The current may be supplied from the mains or from an accumulator or dry battery housed in the base which is then provided with a closure plate on which the accumulator rests and/or with clips for holding it in position. An upstanding flange b<1> on the base receives a cylindrical bottom part a<1> of the reflector, and the screen g is received in a cylindrical upper part a<3> of the reflector. The reflector may be of ellipsoidal shape and the screen may form a continuation of such shape.
