Specification'of Letters Patent. I
' rat'ented' m. 10, 1908;
Application jfiled m 22,1908. Serial No. 444,785.
To all whom it may concern."
Be it known that I, ALoIs REIMANN, a subject of the Emperor of Austria-Hunary, residing at Zizkov-Prague, Bohemia, ustrian Empire, have'in'vented'certain new and useful Improvements in Insulating-Coverin s for Pipes, of which the following is a specification.- 7. The subject of my invention is an insulate ing covering for pipes. v
The new covering isnot only verysimple to apply, but has the advantage that the a continuous insulating layer, and that in the event of the flange-.joints leaking, the steam immediately escapes to the outside without I penetrating'the insulatin material. y
In the accompanyi rawin Figure 1 is l a longitudinal section t ough t e insulating .5 Fig. 2 is a cross section through Fig. 1. i'g. '3 is 'a longitudinalsectional view showing a modificatijon. Fig. 4 is across sectionthrough Fig. 3 Fig. 5 is a lon itudinal section through the casing employe in insulating pipe-joints. Fig. 6 is a part cross section through Fig. 5.
In making theinsulating covering of' the actualpipe l, a cord 2 of asbestos or other suitable material, which has previously been immersed in or painted over with watergh pitch. After the water-glass has well dried in, filamentous glass (spun glass, or glass wool), hereinafter briefly referred to as spun glass, 3 in loose, open condition is uniformly applied between the coils 2 until the spaces are filled up, thatis to say, until the layer 3 of spun glass is at the same level as the cord 2. Hereupon the spun glass 3 and cord 2 are sheathed with paper 4, which has water-glass. This paper sheath ,4 hardens and protects the spun glass layer 3. In addition to the simple paper sheath corrugated paper, painted over with water-glass on the outside, may be employed,- which renders the protective sheathing considerably stronger. This covering 2, 3, 4 is suflicient for ordinary insulating purposes. .If, however, a still more effective insulation is required, the paper sheath 4 is first allowed to dry, and over this first insulating covering 2, 3, 4 a' second similar covering is applied, consisting as before of a cord 2 spun glass 3 and a pro-v tective sheath of paper 4. If desired, one
.as shown in Fig. '3'. p of covering is closed by the vcord 2 being terstice 12 between the latter.
or more extra insulating coverings may be applied to thi'scoverin' 2,-3,-4". Thefcoils 2 should be of high pitc andin the eventof two or more insulating coverings being employed, the coils 2,2 should notv lie'coincident one on the other,- but'should be wound so to sayone between the other, for instance The end of each length wound round the pipe to form a ring, such as shown at 5, 5.
At the pipe oints, made bybolted flanges 6,
' 7, a two-part flange-boxer casing- 8 of wellknown construction is employed,'in'conj unc-. tion with a cage of wires 9, 8, 9: secured thereto. Each wire is bent six times at right angles, so that there are three sections, namely, a central section 9, bridging the flanges 6, 7,?and two lateral sections 9, 9
' which lie in the spacesbetween the'flanges and the rings 5. The-sections 9'- are longer than the sections 9, .so that on opening the box '8 and removing the nuts the -flangebolts can be drawn out without the insulating covering of the pipes having to be disturbed.
. To the interior of the wire cagethere is secured a split troughedring,10, wh1e'h, when the box 8 is closed, bears'with its edges-11 against theflanges 6, 7 covering over'the in- In the event, therefore, of the packed joint leaking, the eshere is conducted to the outside by the outlet pipe 13. In this'manner a leaky joint can be at oneedetected by the issuing steam,'wh1ch, however, can not enter the non-concluctlngcovering material. The space between the box 8 and the wire cage is packed with spun glass 3". The various wires offthe'cage are connected with the box 8 at each end, and owin to their resilience thesplit ring 10 secured to them is firmly pressed against the flanges at its edges 11.-
Having thus described my invention, I claim as new 1.-In combination, a pipe, a cord coated with water-glass coiled round the plpe, spun glass filling the spaces between the cord coils, and paper coated on the outside with-waterglass sheathing the cord and spun glass, substantially as described. p
: 2., In combination, a pipe, and a plurality of superposed insulating coverings surrounding the same, and each comprismg a coiled cord coated with water-glass, spun glass fillcapingsteani enters the trough 10 and from ing the spaces between the cord coils, and paper coated on the outside with water-glass sheathing the cord and spun glass, substantially as described.
3. In combination, coupled flan ed pipes, a cord coated with water-glass coi ed round I each pi e, spun glass filling the spaces between t e cord coils, and paper coated on the outside with Water-glass sheathing the cord and spun glass, a cage consisting of'a plurality of wires bridging the flanges and extending for a certain distance at each side, a cas ing inclosing the cage and secured to it at the I sulation of the pipes a continuous covering, substantially as described.
4. An insulating covering for the joints of flanged Ipipes, comprisin a cage consisting of a plura ity of wires eac bent to present a bridge and two lateral sections, a casing inclosing the cage and havin the endsof the wires connected to it, a spit troughed ring located in the cage and secured to the bridges and presenting an eXit pipe extending to the outside of the casing, and spun glass filling the space between the cage and the casing, substantially as described.
In testimony whereof I afiix my signature in presence of two witnesses.
