Abstract
4129. Hoffay, J. April 3, 1913, [Convention date]. Tool arms and mountings. - In a sound - box having a forked l e v e r straddling the diaphragm, the bifurcations 1, 2 are stressed so as to maintain tension in flexible inelastic means 7 connecting the bifurcations together, and preferably passing through the diaphragm 3. The Specification as open to inspection under Section 91 (3) (a) describes also a duplex sound-box with a single bifurcated stylus arm connected as above to both diaphragms, and a mounting for the stylus-bar consisting of a ring insulated from the body of the sound-box. This subject-matter does not appear in the Specification as accepted.
