Application filed September 18, 1905. SerialNo. 279,060.?-

To all 'LUhO'Tl'L it meg concern;

Be it known dial: i Wane): lxennn Sm CLIFFE, a subject of the King of Great Britaim and Ireland, resident of (iodley, near ',.\lan -hester, England, have invented improved Means for Covering Steam-Pipes, lifrlinders, and the Like, of which the following is a specification.

This in vcntion refers to heat non-conducting coverings for steam )ipcs, cylinders and the like, and consists ol certain novel eonstructions ol' covers by which in the case of llanged pipeslu-ith the llanges as well as the main lengths of the pipes are covered.

Upon the accompanying drawings Figure 1 illnstrl-iles a length. of steam piping with the improvml wverings a )plied thereto, these. latter being shown partly in section and partly in elevation. Fig. 9 illustrates to a larger scale the outer shell or casing of the cover Fig. 3-

used for covering in the pipe flanges. illustrates a longitudinal section of the complete llange cover, and Fig. 4 illustrates a transverse section (in part) of such cover. Figs. 5 and 6 illustrate longitudinal and transverse sectional elevations.

Referring to Fig. l,-(a) is the steam pipe with llanges (b). Encircling the pi )e (a), at salable distances apart, are two or more) hoops or rings Around the hoops thus made and applied is placed a sheet metal covering (1]). by preference, in two longitudinal parts, whe if one extends about two thirds the "way around the hop s, and the other is equal to .rather more. tian the remaining third of the circumference of the hoops, see Fig. (3, so that when put together the two parts shall entirely inclose the pi )e and hoops. Into the space between t m said covering and pipe and prior to the smaller part. of the covering being placed in position, slag wool or like non-conducting material is With the smaller part of the cover then applied, divided clamping bands'hl) are applied, and, by means of nuts and bolts, the two parts of the cover are held iinnly in position around the hoops.

The covering consnf of a cylindrical metal casing (c) with 1-: .2 Fig. and made in two qed to each other along one ems! hy n boll. (f) and nnl n'ls boil irodnlicll by siu1ui- Specification of Letters Patent.

i the metal. The object of thus making the cover IS twofold, lirst-,.it 1s to chenpen thc cost of making, and secondly to produce a l taneously curving, turning'in anrl c'rinip ng and thus well adapted to fit objectsf. of slightly varying formation. A further ob jcct is to give the ends a broad, instead of a sharp edge. Within each half part of such casing is (or may be) a liner (1!), see Figs. 3 and 4, and in the s )ace between it and the casing is a iilling ol slag wool or like heat nonconducting material. The ends of each liner are cranked, and each liner is secured to the outer casing by such ends only, so that the liner shall be free to give and take or spring with the outer casing. The llange covering thus formed isplaced around the pipe flanges as shown in Fig.1, the crimped ends lying against the outer lace ol' the pipe covering ((1), and the free ends of the two arts of the covering being l'nstened to each other by the bolt (f) and nut The erimped ends of the two parts of the casing and free ends of the casing overlap, see Figs. 2 and 4, and thus allows the casing to fit around pipe coverings of slightly varying diameter.

The in'iproved erimped ended flange cover may be applied to the covering in of T-pipes, branches and valves.

of cylinders, the casing (c) is omitted, and the hoops (c), casing (ll) and bands (21) hoops c are made of coiled spring wire, the. diameter of the coils being equal .to the width of the space desired between the pipe and covering and the length being such as to cause it to encircle the. pipe, as shown in Fig. 6, and cling thereto. At its ends the wire formed as hooks, so that on being applied to a. pipe the ends may engage and thus hold the wire to the pipe. This nnproved coiled wire hoop may be applied to cylindersas well as pipes.

What l claim is:---

l. in heat non-eomlucting coverings for steam pipes and their llanges, sheet metal casings in two longitudinal pails; annular collars composed ol' lengths of .oilcd wire 1 encircling the pipes and ly-ing between the pipes and said casings whereby lhe casings are held away l'rom, and eonc'enli'ic to the j pipes; a bent non-comlueling lnele 'inl in he covering which is very strong and durable and is considerably elastic circumferent ally" In applying the invention to the covering made to a larger scale are alone used; The

lit)

with its ends turned inwards and crimped, a

liner within each part cranked and held at each end, a heat non-conductin material in the space between the liner an casing, and in means for securing the two parts of the easing together, substantially as set forth.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
