Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1920 edition. Excerpt: ...formed of the non-porous Johns-Manville Packing Cup, held air-tight against the cylinder walls by the Johns-Manville Expander Ring. The Johns-Manville Packing Cup is made of plies of asbestos fabric, impregnated and formed under enormous pressure. It is non-porous--air-tight, made to withstand wear, heat, pressure, friction, oil and condensate. Furthermore it fits--snugly, and never becomes porous in service. The Johns-Manville Expander Ring is of the best cold-rolled and spring steel. Instead of a mere loop of wire, with the pressure on the cylinder wall exerted on a line tangential to the round section of the wire, and usually with less than an eighth of an inch bearing surface, its band of spring steel holds the packing cup tightly and evenly over a half-inch of bearing surface all around the cylinder. The Johns-Manville Packing Set--one of the greatest of modern brake improvements--practically eliminates air-leakage in brake cylinders. Made to fit all standard sizes of brake cylinders, it can be applied without change of any of the parts of the equipment, and has proven, in actual service tests, to reduce maintenance costs, with increased braking efficiency.
