Healthy houses : a handbook to the history, defects, and remedies of drainage, ventilation, warming, and kindred subjects : with estimates for the best systems in use, and upward of three hundred illustrations . , subjectto matting together, such as hair or straw, had effectually stoppedup the pipes, this was removed by the action of a screw at the endof the furthermost rod. Most of the London builders are providedwith rods of this description, but only use one anti-friction roller,and this at the extreme end of the screwed-up series. In sewersproperly so called, where personal access was impossible, and breakingup the ground unwarrantable, something still stronger than theabove is requisite. Messrs. Fricker and Manley, in 1861, constructedan instrument formed of a bar of wood, with- numerous blades fixedon its length in the plane of the thread of a screw. A series of theseswivel-jointed, were dragged through the sewers, by which means thesediment was agitated and beaten up, and preparation made for athorough flushing. I will now notice the various shaped junctions, bends, and syphonswhich are used with glazed earthenware pipes. JUNCTIONS, BENDS AND SYPHONS. 0731 @~—] mr^~i @£ I <3 1 Li.

They can beordered by these names without any fear of mistake. The T-shapedjunction Fig. 30, the Y-shaped junction Fig. 31, and the U-headedjunction Fig. 32, are those used in diverting the heads of drains or incollecting two drains into one channel. The tapered pipe, Fig. 29,simply reduces a large-bored pipe to one somewhat smaller; Fig. 33 Junctions, <£c—Prices of Pipes, &c. 15 exhibits what is called a shaft top, the shaft bottom resembling inshape Fig. 38, the rise of these in brick and other built up drains andsewers is obvions.
