Show Laminated 1'ipe We have already staud that "laminated pipe" would be iscd instead of iron,, io constructing 'he city wter work. As many of our ' readers n ay not undrrstacd what lam- I muted pipe is, or how ic is njunnfac-turcd, njunnfac-turcd, we give the following data as to tho substance and manufacturo of tbe p pc, token from he circular of the pitcnteo of ihe process, Mr. Pairic. fbe p'pc is manufactured "by wind- i ng broad thin hoops, or lamina, of food (made continuous ty joining the rijd-J fpirally urouiid a Ibrm of the size f ibo pipe nqiired, eveiy alternaie layer being wound in an opposite dirt c-tton c-tton to tho last, aijd crossing it diag-ooally." diag-ooally." The thick upas of the pipe is r-KuUled by the amount of pressure it will he required tu sus;aiu. Whko oak is the wood usually used, and where icvcr-tl lamina or strips are wound rogechor iu opposite directions, the pipo is strong enounb to withstand the -everest teats of hydrau'ic pressure, o addition to the fact that wood sato-I sato-I rated with moisture and excluded" from the air, lasls, under these conditions, condi-tions, for a long time, tho wooden lamina " arc thoroughly saturated satura-ted with boiling asphaltum, which makes tbe pipe as durable as if made of cast . iron. The connections of see: ions of tho pipe in tho direct main arc made with sleeves made in tho same manner and of tho same material as tho pipe itself, but elbow connections connec-tions aro of cast iron. This pipe is vouched for by numerous testimonials based upon experiuiQQt, as being as durable as ordinary hoq pipet a,nd as answering exuetly tho samo purpose, and being much cheaper it is usurping the place of iron piping as a water conduit. |
