Abstract

749,551. Stuffing-box substitutes. HUTCHINGS, E. L. Nov. 18, 1954 [Nov. 18, 1953], No. 31922/5/53. Class 122(5) [Also in [Group XXVIII] A diaphragm has a multiplicity of indentations, dimples, protuberances or the like formed in it in.a pattern alternately raised and depressed radial strips and of alternately raised and depressed concentric rings so that it may flex in operation without any appreciable stretching or contraction of the material from which it is made. The indentations c, d may be four- or six-sided pyramids which protrude to either side of the diaphragm. To enable the diaphragm to be clamped, a peripheral flat portion a is provided while to enable it to be attached to a reciprocating rod or other means, a flat portion b may also be provided. The diaphragm may be made from metal or resin-impregnated fabric. One or more pair of diaphragms may be joined together to form a bellows, the outer walls being either plainly cylindrical or provided with indentations similar to those of the diaphragms. The Provisional Specification states that the indentations in the diaphragms may be hemi-spherical.
