The threading of pipe in connectingis a source of much time, labor andmoney expenditure and these lossesmay be eliininated by the use of thegrip principle in connecting. Grip fit-tings, consist essentially, as shown inthe cross section of a coupling, of alead wedge-shape packing over whichmoves another gland wedging in theopposite direction. The second wedgeis pushed forward so as to grip theother when a screw top is screwed. GRIP PIPE ;.^ .\XI)VIEW, ECTIONAL towards the joint. Tlie two ends ofthe pipe are thus gripped and en-cased by a single coupling and thread-ing of the pipe itself is principle is used in all types offittings and all sizes including a longsleeve connection to span a 4/i inchopening, a simple coupling, an ell fit-ting in which the inside surface isflush and without pockets, and a sliptee. In using grip couplings the pipeends project past the shoulder for thelead seat ]4 inch or more and thenthe nut is screwed up until the jointis tight in the body. These fittingsare made ot malleable iron and areclaimed to stand any pressure up to2,000 pounds. They are claimed tosave two-thirds in time and fittings are made by the WareCoupling and Nipple Co., Ware, Mass. PROTECTING PAINT FOR STAND-PIPES AND TANKS.
