Application iled'eiitember e, 1912. Serial No. 718,571.v

To all wfzomz'f mag/.concern Be it known that we, JOHN lll. FARLEY, lvlATrLnA S. Finnair, and DAVID l?. FARLEY, citizens of the United States, residing at Cleveland in the county of Cuyahoga and .State of Gino, have invented certain new and useful improvements in Ceiling-Sleeves for Fluid-Pipes, of which the following is a specicatien.

This invention relates to ceiling sleeves for iiuid pipes, such as steam, hot water, hot air and other pipes placed in buildings for circulatipg fluids, all substantially as shown described and particularly pointed out in the claims. Y

ln the accompanying drawings, Figure l is a vertical sectional. elevation of our new and improved sleeve members lin working relation, a section or" a pipe and a cellular asbestos or like covering for the pipe inclosed by the said sleeve members. Fig. 2 is a side elevation, reduced of the several parts shown in ll ig. i. Fig. 3 is a perspective view of the upper of said sleeve members, and Fig., llis a perspective view of the lower Vof'said members, the same being in section or in two l getlier as one.

The invention as thus shown comprises two sleeves, A and B, respectively, and means for fastening said sleeve together and adapted to be used in insulating pipes, tubes and the like Where they pass through ceilings or lioors in buildings, and while we 'carts adapted to be bound topreferably show and employ a cellular asbestos covering consisting of sections C and C for the pipe l) it should be understood that any preferred style or kind of nonconducting covering can be used'. However, a cellular asbestos covering as shown herein is deemed the best, and in the practical use or application of the sleeves it is customaryl to place the covering on the pipe and ,the sleeve A about the covering before the ceiling or floor is laid and then to build up to the sleeve. In such case the serratedor toothed top flange 2 rests upon the licor and the section C comes on the inside and rests on flange 3 of the sleeve. '.lliefsaid sleeve A is split lengthwise and has a tongue e at one of its vertical edges adapted' to engage slot 5 at the other of its ver tical edges and 'provide for diderences in size of covering, and flange 3 below is radially slitted or divided to spread the same horizontally, and thus the sleeve ii is made an inclosing andv supporting part :tor the packing or covering which passes Talenten apr.. ao, isis.,

through the floor and serves as a protection thereto against heat in the pipe P. The saidv sleeve A also has a bead 6 about its lower portion which both affords strength and becomes 'a medium of support Jfor what we term the grab sleeve B suspended from or upon said bead. Thus it occurs that the upper covering part Gis supported or carried by the flange 3 and is placed in position as the building is being erected and the said sleeve A also becomes a means of support for the sleeve B engaged thereon as shown.

The sleeve B is supplementary tosleeve A and serves to eieot a jointed connection of the pipe cover therein. To"this end the sleeve B is made a two-part or two-section member adapted to be engaged about theA upper or meeting end of the Alower'section C and also about the upper sleeve A. Thus the sleeve B has an upper inner annular groove 7 of a size to t comfortably upon the bead 6, and an annularbead about its lower portion serving as a'support -tor the clamping band b, and also has serrations or teeth 9 extending inward at its lower edge adapted to bite or grab into the sect-ion C and help to hold it up in a sustained and closed contact against the end of the upper 'section C. The said sleeve B is made in two separate parts or halves because they are of sheet yinetal and,v being beaded, cannot be bent to open as would be required if they were made in a single piece. As it is the said parte or halves are cut to size to inatch at their `edges'when itted closely upon theA sleeve A and their teeth 9 are adaptedto tongue 10 vand theother a slot l2 through which said tongue engages and can be bent back into lockingy position. 'Finally a suitable sheet metal band o or its equivalent,'

vengage in section C, and one part has a say a tie wire or wires',"is placed about the body of sleeve B between its beads endg, l clamped or otherwise tightly lined thereon. f

By the foregoing construction no portion of the covering can leave the ceiling to show dirt nor break the ceiling by expansion or contraction ofthe supporting parts. The band l) is preferably lacquered' if it be of a strip of thin sheet metal and is shown as having a Wire loop 13 in its end adapted to, be engaged by the tongue 14 but, as already stated: a suitable binding of wire maybe ier y used for this purpose. A Covering of Canvas, not shown, may be drawn over all the exposed portion ofthe joint to improve the appearances. lt is customary to put on one piece of cloth Where risers are exposed from lcop to bottoni in the rooms. No oeiling'plates are required With this structure and there is no danger of tearing` the ceiling while doing the work, as oeeurs when oeil- ,ng plates used and which are liable to tear the ceiling when the pipes expand un` der a high heat.

That We olann is:

l. A pipe and an asbestosI covering tube about the same in a hole in a-iloor and an asbestos extension tube next beneath said covering tube about said pipe7 in combination with a split sleeve about said tube having an outwardly turned flange about its top at the top of said hole and an inwardly turned flange at its bottoni on Whiolrsaid covering tube rests and vprovided with a bead about its lower portion and means at its meet-ing; edges to lock said edges together, and a grabbing sleeve having an annular groove engaged over said bead and bestos extension tube.

2. A. pipe and an asbestos covering tube about the same in a. hole in a floor, a split sleeve in said hole about said tube having an outwardly extending projection about its top and` inwardly extending projections at its bottom engaged beneath the lower end of said tube, in Combination with tWo part sleeve suspended upon the lower portion of said splitsleeve and having` inwardly ex tending pointed teeth at itsl lower edge, an extension asbestos tube abutting said eovering` tube and penetrated and held by said teeth and a band about said two-part sleeve clamping the saine on said split sleeve and about said extension tube.

ln testimony whereof We atlix our signatures in presence of two witnesses.
