ENGINEERING COUNSEL Our engineering staff is always at your service to solve your individual problem. We shall be pleased to submit to you our analysis and recommendation for ah efficient and economical solution to your vibration problems. 508 Vibration Control Dnrices The Korfund Company, Inc. 48-01R 32nd Place, Long Island City 1, New York Representatives in Principal Cities. See "KORFUND" in local phone director; or in "Thomas* Register." Specialists In Vibration & Noise Control for Over Half a Century. For a discussion of Vibration control theory and chart for determining deflections required, see "Controlling Vibration From Machine Mountings" at end of Chapter 40. If in doubt about product selection, submit data on make, type, rpm and model number of equipment and type of floor for specific recommendations, without obli gation. STEEL SPRING VIBRO ISOLATORS provide greater deflec tions with isolation efficiencies approaching 100 percent. Though more expensive than rubber or cork, they are sat isfaction guaranteed and provide maximum overall economy because: they eliminate bolting, speed equipment installation, usually eliminate special foundations, permit trouble-free upper floor installations, and will usually outlast the machine. Series L Isolator THE SERIES L VIBRO ISOLATORS contain from one to twelve steel springs of proper stiffness depending upon the loading and deflection desired. Loading: 75 to 23,000 lb. Maximum deflection 2 in. (special designs available for higher loads or larger deflections). Isolators are usually installed directly under machines (occasionally under steel bases or foundations supporting equipment). They have ad justable snubbers to control movement and built-in leveling bolts, a Korfund feature for over 30 years. SERIES V VIBRO HANGERS: load range 20 lb to 3,800 lb. Vtbro-Hanger Maximum normal deflection 1 in. (larger deflections on re quest). For suspended equipment installations, also as vibra tion-absorbing pipe hanger. RUBBER AND CORK provide good sound insulation. How ever, rubber is not very effective as a vibration absorber for disturbances below 1200 cpm, is fair from 1200-1800, and good above 1800. Cork is effective only above 1800 cpm. Elasto-Rib Pad SERIES R RUBBER-IN-SHEAR HANGERS: Similar to spring hanger illustrated but incorporating rubber mountings of varying stiffnesses for loads from 10-1,000 lb. ELASTO-RIB has a core of high-grade cork plate, permanently bonded between two layers of deep-grooved, Neoprene rubber. Just set the machine on Elasto-Rib--no fastening to floor is normally required but can be cemented or bolted if desired. Excellent sound insulation characteristics. Loading up to 60 lb per square inch. Also furnished as Elasto-Rib Dampers with load distributing top plate and built-in leveling bolt. Newt Motor Base with Built-in Slide Rails ARMSTRONG'S VIBRACORK & KORFUND LIGHT DEN SITY MACHINERY CORK are strong, durable machinery isolation plates made of pure cork granules compressed and baked under pressure with accurately controlled density. Furnished in three densities for loads from 400-8,500 lb per square foot. 1 in., 2 in., 3 in., thicknesses. Plates 12 in. x 36 in. DUPLEX TWIN RAIL FAN & MOTOR BASES: Rugged con struction and built-in chocks to maintain alignment. Rubber or cork isolation. Advantages of separate fan and motor bases: no motor noise transmitted through ducts--complete adjustability permits job-site changes in motor position, belt length, rotation, equipment bolt location--quicker delivery of drawings and bases--easier handling--lower transportation costs. Integral type bases also available. Duplex Bases FOR ADDITIONAL DATA, SEE SWEET'S FILES OR WRITE FOR CATALOG 509
