STOVEPIPE THIMBLE.

Appnation mea February s, 1222. serial No. 534,522.

To all whom t may concern.'

Be it known that I, JAMES M. MEADE, a citizen of the United States, and a resident of Honeoye, in the county of Ontario and State of New.Y'ork, have invented certain new and useful Improvements in Stovepipe Thimbles, ication.

This invention relates to an improvement in stove pipe-thimbles es ecially adapted for use between the floor an ceiling.

The object of the invention is to provide an improved stove pipe-thimble of this character which is so constructed and organized as to be'absolutely fireproof and as to completely'insulate the adjacent structure of the building from the stove -pipe s o that the building will be protected and lire will be prevented irrespective of the degree to which the stove pipe may become heated.

Another object is to provide a device of this character which is of extremely simple and durable construction, reliable and safe of which the following is a speciin operation, ornamental in appearance and comparatively inexpensive to manufacture.

Other objects and advantages of the nvention reside in certain vnovel features of construction, combination and arrangementI of parts which will be hereinafter more fully described and particularly pointed out 1n the appended claims, reference bemg had to the accompanying drawin forming part of this application, and in w ich: t

Figure lis a view in elevation, illustrating thepreferred embodiment of the invention; in which portions are broken away and shown in section for the sake of illustration ;v

Figure 2 is a plan` view; and

Figure 3 is av view in transverse horizontal section.

Referring to the-drawing whereinfor the sake of illustration is shown the vreferred embodiment of theinvention, it wi l be seen that my improved stove pipe thimble comgrises in general two telescoping sections,-

esignated generally at 10 and l1, respectively. The section 10 comprises an inner cylinder 12 and an' outer cylinder 13 arranged in spaced concentric relation and constituting a pair of cylinders. The cylinders 12 and 13 are maintained in spaced concentric relation by means of a plurality or set of arms 14 which may be integrally formed with the inner cylinderk 12 and which are extended across the space between the cylinders and `inner cylinder 15y and an ranged at one Iarms 17 bent around and secured to the der .13, as indicated at 14:a Slmilarly the section outer cylinin Figure 1.

11 comprises an outer cylinder 1.6 malntamed in spaced concentric relation wlth respect to the by means of a plurality or set of arms 17 whlch may be mtegrally formed with the outer cylinder inner cylinder 15 and secured to the outer cylinder 16'. as in the other section.- As shown 1n Figure 1, the arms 14 lare arend of the thimble andthe are arranged at the opposite ends thereof so that these arms do not interfere or obstruct the telescopic engagement of the sections.

cylinder 13 but the cylinder 15 is spaced a substantial distance from the cylinder 12. 'I he stove pipe which is indicated in dotted llnes extends through the cylinder 12.

Shells of heat insulating materiahdesignated at 18 and 19 encase the inner and outer cylinders 15 and telescoping section, and a shell 20 of heat atlng material encases the inner cylinder 12 of the inner telescoping section 10. These shells of heat insulating material are preferably constituted by combining as: bestos cement with mineral wool 'and the resultant product is an` extremely eiiicient nonconductor of heat.

Metallic collars, indicated at 21 and 22 are provided and are secured to the outer cylinder 13 of the inner section 10 and the outer cylinder 16 of the outer section 11,

t is tofbeunderstood of coursel Ithat the cylinders 12and 13 land 15 and 1-6 16 respectively ofthe outerl 22 are arranged adjacent but'slightly spaced from the ends of the thimble, as clearly shown in Figure collars is important since these collars engage the floor and ceiling, since by spacing them from lthe ends of the thimble they are more effectively isolated and are prevented from conducting or transmitting` heat tothe adjacent structure of the building.

1. This disposition of therespectively, and

A casing of wire mesh, designated at 25 extends between the collars 21 `and 22 'and aboutl the periphery ofthe outer section.

By constituting the enter casing of -wire mesh the asbestos shell 19 is protected and enclosed and at the same time the disadvantages of an impervious metallic casing are avoided. Rods 26 and 27 are provided, and extend longitudinally of the thimble, the ends of the rods being secured to the collars 21 and 22. `When these rods vare placed in position andA secured to the collars 21 and 22, the sectionsY l0 and 1l of the thimble are held against relative movement and if desired adjustable andI releasable means may be provided for securing the rods to the collars as for instance the rods may be threaded at their ends and nuts may be provided which coact with the threaded ends and which engage the collars. llf this expedient is resorted toa pair of nutsfmay be utilized with each end of each rod with one of the nuts engaging one side of the collar and the other nut the opposite side of the collar. v

ln practice, the thimble may be readily I adjusted or adapted for various types oi stove pipes and maybe readily assembled therewith andl with the adjacent structure of the building. l/Vhen the stove pipethimble is assembled with the stove pipev i and with the building itl so insulates the pipe as to 'effectively prevent the building from catching on fire from the stove pipe and this irrespective of the degree to which the stove pipe is heated. Moreover the arrangement is such that neither the structure nor the effectiveness of the thimble is `impaired by highly heating the stove pipe,

the organization of the cylinders and shells l together with the wire mesh casing and the arrangement of the collars 2l and 22 previenting deterioration and bringing about the advantageous results above enumerated.
