meanes To all whom it may concern: I

Be it known that I, Josnrn Mnssnvh, a V j ing drawing, although no restriction is necessarily made to the precise details of con? 1 citizen of the United States, "residing at Benld, 1n the county of lVlacoupinIandState of Illinois, haveinvented' new and useful Improvements in 'Stovepipesfof which the following is'a specification. s

This inventionrelates to astove pipe and i more particularly to a stove pipein which the "section and provided 'at one end'with apipe sections from which the stove pipe is formed are so constructed and arranged with relation to each other as to render the stove pipe extensible.

The prlmary object of the invention is to provide a stove pipe of this character where in a sleeve engaged with one of said sections is movable longitudinally of the other pipe spring finger engageable with depressions in the pipe section on whi'chthe sleeve is mov-' able to hold the sleeve adjusted position thereon. V I

Another object of the invention is to provide the pipe section upon which the sleeve is movable with a circumferentially extending groove arranged near theend of the-pipe section which is received within the sleeve and which whenbrought into engagement with the spring fingeron thesleeve prevents 1 .said pipe section from being withdrawn from within the sleevefduring the adjust- "pipe section upon'which the sleeve is'adj ustthe'escape of smoke from- 40 ment of the same.

-A further object provide the sleeve which connectsthe pipe sections with an inturned portion at one end thereof which provides the sleeve with an internal collar which snugly encircles' the able and prevents 4 between the sleeve and pipe section irrespective of the position of the sleeve upon said section. v

A still further object of the invention is to provide thesleeve which is adjustable upon one of the pipe sections wlth an 111- turned flange which'when brought 1nto contact with a circumferentially extending bead on the'other pipe section serves to support."

Referring now the numeral 1 designates the improved stove pipe which comprises pipe sections 2 and 3 connected through the medium of a sleeve '4 into which each portion of'its length, said sleeve" 4 being to render the stove pipe extensible and to allow an end 5 on the pipe'section2 to be pipe section .2 V

or the like. The sleeve 4 has formed thereon .at "the endin which the end 6 of the pipe'section 3-:

is received an inturned flange 8 Contacting} .with a circumferentially extending bead .9

on the-pipe sect1on-3,said flange and bead limiting the extent to which the end -6' of the pipe section 3"may extend within said sleeve and also providing a support for said sec-v 7 tion which enables the pipe section 3 to be moved when the sleeve 4 is moved longitudinally of. the pipe section 2. The other end of the sleeve 4 throughwhich passes the pipe section 2 has an inturned collar 10 withinthe sleeve, said collar snugly encircling the pipe section '2 and serving to prevent sleeve 4 and pipe section 2 irrespective of the position of the sleeve 4 upon said pipe section. 7 The sleeve 4 hasformed therein a pair portion forming a the escape of smoke between 'theof spaced slits 11 extending longitudinally of the sleeve 4 the entire length of the coll-an 10 to enable the portion of the sleeve which is arranged between the slits to provide a spring finger 12 which extends beyond the slitted end of thesleeie and is providedwit'h a transversely extending groove; forming-- upon the finger 12 a locking rib 18 terminatlllglrllni an' out-turned releasing; lip; 14.- V
