FLUE-IE'IPE SUPPORT AND INSULATQR.

Application filed December 10, 1924.

portand insulator for fine pipes for gas heaters and the like which operates to center, effectively support, and maintain a due pipe in proper spaced relation to the infiannnable parts of the ceiling and roof of a building whereby a passage around the flue pipe provided through which air is free to circulate. thus reducing to a minin'ium the possibility of fire. It is also a purpose of my invention to provide a fine pipe support and insulator which in addition to possessing the desirable qualities of simplicity,durability and inenpensiveness, is capable of application to the two ends of a fine pipe, and in practice the device at the lower end of the pipe supports thelatter, while the device at the upper end of the pipe. is inverted to receive, center and hold the pipe in spaced relation to the inflammable parts of the roof through which it extends.

I will describe only one form of pipe support and insulator embodying my invention and will then point out the novel features in claims.

In the accompanying drawings,

Figure 1 is a view showing in vertical section one form of flue pipe support and insulator embodying my invention in applied position with respect to a fine pipe;

Figure 2 is an enlarged transverse sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a perspective view of the device shown in the preceding views.

Referring specifically to the drawings, in which similar reference characters refer to similar parts, my invention, in its present embodiment, is shown in Figures 1 and 2 as comprising a body 15 formed of sheet unetal or other suitable material which, in

the present instance, is circular and hollow, one end of the body being formed with a flange inturned to provide an annular collar 16. The collar 16 is formed at circumferentially spaced intervals with openings 17,

and its inner peripheral. edge is bent inwar-(1y and downwardly to form an ai'inular lip 18. liitl'iin the body are arranged a piurality of retaining members 19. lin the present instance I have shown three retaining members spaced 120 dliil'b and eacl member con'iprising a leaf spring secured at its ends by rivets or othe" suitable fasteir ing members 20, while its i tion is bowed inwardly so as to engage the periphu'y or a flue pipe inserted therein.

As shown in Figure 3, the opposite end of the body 15 is split at intervals as indicated at 21, to provide tongues 22 which can be bent outwardly at right angles to the periphery of the body to provide attaching means tor sci'uring the body to a support. In practice, the body 15 is covered with a jacket 23 of asbestos or other suitable material for the purpose of preventing the radiation or heat through the body to the parts of a building with which the device contacts when in applied position.

Referring now to Figure 1, T have here shown a conventional form oi flue pipe in cluding a lower section 24 and an upper section 25, the former being supported in upright position by one of the combined supports and insulators embodying my invention. In the applied position of the device it is inverted so that the collar 16 is disposed at the lower end of the body 15 to engage the lower endof the pipe 2% and support the latter. The lip 18 is disposed inwardly of the pipe end, as illustrated, and thus serves to properly center the pipe within the body. However, the retaining members 19 co-operate with the lip 18 in confining the pipe against lateral movement within the body and to thus maintain the pipe in properly spaced relation to the body so as to provide between the two a circular passage 26. through which air is free to circulate. The perforations 17 in the collar 16 allow the passage of air upwardly into the chamber 26. The body 15 is securely held in the ceiling of the building by driving through the angularly disposed tongues 22 nails or other suitable fastening members, the latter puncturing adjacent parts or the ceiling structure 1. ntermediate porwhereby the device as a unit is firmly held within the opening of the ceiling.

To maintain the upper pipe section 25 in proper spaced relation to the roof of the building, another combined support and insulator is provided which in applied posillU upwardly therethrough, the air passing out of the chamber througl'i the perforations 17.

With the two devices applied as just described, it will be manifest that they co-oper ate in firmly supporting the pipe sections in upright position and in maintaining the same in spaced relation with respect to the adjacent inflammable parts of the ceiling and roof, so as'to allow the free circulation of air therebetween and thus reduce to a minimum the possibility of fire. Whatheat is conducted from the pipe through the body of the device is prevented from being transmitted to the adjacent parts ct the building structure'by virtue of the jacket insulating material 23.

Although I have herein show and described only one form of flue pipe support and insulator embodying my invention, it is to be understood that various changes and modifications may be made Without departing from the spirit of my invention and the spirit and scope of the appended claims.

I claim as my invention:

1. A support for flue pipes comprising a hollow body having one end bent over to form a collar and inwardly to provide an annular lip on the inner periphery of the collar, said collar formed with circumferentially spaced openings, resilient members for movably holding the pipe in said body, a heat insulating jacket enclosing said body and the opposite end of the body being split at intervals to form bendable tongues.

2. A support for flue pipes comprising a hollow body, a collar formed on one end of the body, an annular lip on the inner periphery of the collar, and retaining members in the body, each comprising a resilient element adapted for frictionally engaging the pipe and co-operating with the lip to center the pipe in the body.
