. Ingegnere meccanico ferroviario . La morsa per tubi Whittington è facilmente trasportabile in qualsiasi kit di utensili ed è di forte costruzione. La mascella flottante è guidata sul corpo del visone, dando un sostegno sostanziale ad esso. COLLEGAMENTO PER TUBI FLESSIBILI UN collegamento per tubi flessibili, costituito da una confezione con giunto sferacon amianto intrecciato da 4 in., è stato recentemente collocato sul mercato dalla Franklin Railway Supply Company, 30 ChurchSt. Xew York City. E' di costruzione semplice, come mostrato. Giunto sferico del tubo flessibile b- l'illustrazione. Per imballare la giunzione, è possibile utilizzare l'imballaggio standard in amianto quadrato o rotondo

. Railway mechanical engineer . Whittington Pipe Vise is easily carried in any kit of tools and is of strong con-struction. The floating jaw is guided on the body of thevise, giving a substantial support to it. FLEXIBLE PIPE CONNECTION A flexible pipe connection, consisting of a ball joint packeawith 4-in. braided asbestos, has recently been placed on themarket by the Franklin Railway Supply Company, 30 ChurchSt.. Xew York City. It is of simple construction, as shown. Flexible Pipe Ball Joint b- the illustration. Either the standard square or roundasbestos packing may be used to pack the joint. This is ofconsiderable advantage in that no special gaskets are requiredand the joint can be repacked at any shop or enginehouse. By tightening the packing nuts, the packing is squeezed intoplace, completely filling the space between the metal rings.The packing nut is prevented from working loose by a cotterpin which e.xtends through a hole in a lug on the body of thejoint and a hole on the packing nut. These flexible joints can be used for both steam and airand with standard piping will replace rubber hose in manyplaces. They are especially adapted for use in roundhouseblower and blow-oft lines, terminal coach heating lines, pumptesting racks, etc. They can be used also to advantage in themain reseroir connections on locomotives, where flexibilityis a desirable feature, and thereby eliminate pipe failurescaused by a rigid union joint. The joints are made
