by a movement of the clamping-ring longitudinally of the pipe-sections, whereby said pipe-sections are insulated from each other; said ring is insulated from the pipe-section passing therethrough, and provision is made for the movement of the said pipe-section through said ring to allow for expansion and contraction, substantially as described. (2.) The described combination, with two pipe-sections, of a clamping-ring for each pipe-section, provided with an aperture through the same for the passage of its pipe-section therethrough, means for insulating the adjacent ends of said sections from each other, means for insulating each of said rings from the pipe-section passing therethrough, clamping means for drawing said rings toward each other to compress the insulating material whereby said pipe-sections are insulated from each other. Each pipe-section is insulated from the ring through which it passes, and provision is made for the free movement of each of said pipe-sections through their respective rings and through the insulating material to allow for longitudinal expansion and contraction, substantially as described. (3.) A pipe-coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, including among its members a cylindrical portion, a clamping-plate adapted to surround one of said pipe-sections, and provided with clamping-bolts, and an insulating- and packing-ring having a portion interposed between said cylindrical portion and said plate, and an insulating-sleeve portion surrounding said pipe-section between it and said plate, substantially as described. (4.) A pipe-coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, including among its members a cylindrical portion adapted to extend over the end of one of the said pipe-sections, a clamping-plate adapted to surround said pipe-section, and provided with a packing-recess on one side, and a packing- and insulating-ring having a portion adapted to be interposed between the said cylindrical portion and said plate, and to occupy said packing-recess, and an insulating-sleeve adapted to extend between said plate and said pipe-section, substantially as described. (5.) A pipe-coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, including among its members a cylindrical portion to receive one end of a pipe-section, provided with an annular edge V-shaped in cross-section, a clamping-ring adapted to surround the pipe-section, the end of which is inserted in said cylindrical portion, provided with a packing-recess and clamping-bolts, and a packing- and insulating-ring adapted to fit said packing-recess, provided on one end with an annular groove, V-shaped in cross-section, to receive the end of said cylindrical portion, and at the other end with an insulating-sleeve portion interposed between the said plate and said pipe-section, substantially as described. (6.) A pipe-coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, including among its members a cylindrical portion to receive one end of a pipe-section provided with an annular edge V-shaped in cross-section, a clamping-ring adapted to surround the pipe-section, the end of which is inserted in said cylindrical portion, provided with a packing-recess and clamping-bolts, and a packing- and insulating-ring adapted to fit said packing-recess, provided on one end with an annular groove, V-shaped in cross-section, to receive the end of said cylindrical portion, and at the other end with an insulating-sleeve portion interposed between the said plate and said pipe-section, and insulating material engaging the end of said pipe-section, substantially as described. (7.) A pipe-coupling for uniting the ends of two pipe-sections and insulating them from each other, comprising among its members two clamping-plates adapted to surround said pipe-sections, each provided with a packing-recess and apertures for clamping-bolts, a coupling-sleeve adapted to extend over the adjacent end portions of the said pipe-sections, packing-rings adapted to engage said packing-recesses and to engage the ends of said sleeve, one of said rings being provided with an insulating-sleeve adapted to be interposed between one of said pipe-sections and the clamping-ring through which it passes and the clamping-bolts, substantially as described. (8.) A coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, comprising among its members two clamping-plates, each provided with an aperture for the passage of the pipe there-through, and a packing-recess, a coupling-sleeve adapted to cover the adjacent portions of the pipe-sections between said plates, the packing-rings engaging said packing-recesses, and adapted to engage the ends of said sleeve, one of said rings being provided with an insulating-sleeve adapted to lie between one of said plates and the pipe passing there-through, insulating material interposed between the ends of said pipe-sections and the clamping-bolts for uniting said clamping-plates, substantially as described. (9.) A coupling for uniting the adjacent ends of pipe-sections and insulating them from each other, comprising among its members two clamping plates each provided with an aperture for the passage of the pipe therethrough and a packing-recess, a coupling-sleeve adapted to cover the adjacent portions of the pipe-sections between said plates, the packing-rings

engaging said packing-recesses, and adapted to engage the ends of said sleeve, one of said rings being provided with an insulating-sleeve adapted to lie between one of said plates and the pipe passing therethrough, an insulating-sleeve engaging said pipe within the coupling-sleeve, and having a flange engaging the end of the pipe, and the clamping-bolts for uniting said clamping-plates, substantially as described.
