\NVENTOR WIT N ass E s ATTORNEY ELMER A. PETERSON, OF ALVIN, ILLINOIS.

STOVEPIPE.

Application filed June 8. 1918.

To all whom it may concern:

Be it known that I, ELMER A. PETERSON, a citizen of the United States, residing at Alvin, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Stovepipes, of which the following is a specification.

This invention relates to a stove pipe and has for its principal object the production of an efficient means for holding the stove pipe against disassembly when in use.

One object of this invention is the production of a stove pipe connection which consists of a clamping band which is bound in engagement with a plurality of pipes at the joint thereof, thus holding the two sections of the pipe in positive engagement with each other and forming a smoke tight joint.

Another object of this invention is the production of a stove pipe connection for connecting the pipes in engagement with the chimney to which the same is attached.

Another object of this invention is the production of a stove pipe connection which consists of a thimble to engage a section of a stove pipe, together with an expanding means for binding the thimble in,engagement with the chimney.

Broadly stated, the invention consists of a plurality of interengaging stove pipes,

clamping bands positioned upon the junctions of the pipe, means for drawing the ends of the bands together for holding the pipe sections in engagement with each other, a thimble engaging one of the sections, a turnbuckle having threaded stems engaged therewith, heads carried upon the ends of said stems and binding within the thimble A for binding the thimble in engagement with the chimney, thus holding the sections of the pipe against displacement.

One practical form of construction and assembly of the present invention will be hereinafter described and is illustrated in the accompanying drawing, in which Figure 1 is a sectional view through a pair of stove pipe sections, showing the clamping band in place.

Fig. 2 is a lo gitudinal section through the connecting thimble and the stove pipe section. also showing the turnbuckle and the heads thereof in section and illustrating the manner in which the same are used.

Fig. 6 is a detail perspective view of a. complete clamping band, and

Fig. 7 is a detail perspective view of the turnbuckle and the heads connected thereto by the stems.

In the preferred embodiment of the present invention, about to be described, it will be seen that the device is used in connection with a plurality of stove pipe sections 10 which'have unobstructed end portions 11, while the opposite ends thereof are corrugated as indicated at 12 and extend diagonally to the side surfaces of the sections, as indicated at 13. It will also be noted that an annular bead 14 is formed on the section adjacent the corrugated portion 12 thereof, as will be seen by referring to Figs. 1 and 2. It is obvious that by having the end portions cut off diagonally to the sides of'thc section, as indicated at 13, the corrugated portion 12 may be easily slipped into the unobstructed end portion 11 of the next adjacent section.

In order to bind the two sections in engagement with each other there is provided a clamping band, the construction of which is clearly set forth in Figs. 3 and 6. The clamping band 15 is provided with an annular beading 16 while the ends 17 are spaced apart, thus permitting the clamping band 15 to be placed over the end portions of two sections of the stove pipe, while the annular beading 14 of one section fits within the annular beading of the clamping band. This clamping band is provided with plates 18 fixed thereon as indicated at 19 upon each side of the annular beading and also adjacent the ends 17 of the band 15. The plates 18 have sleeves 20 formed thereon which carry the pins 21 having central loops 22. A bolt 23 has an eye 24 carried upon one of the loops 22 while the opposite end of the bolt is removably extended through the re aining loop and carries a winged nut 25. Therefore. it is obvious that as the nut 25 is screwed onto the bolt 23, the bolt will draw upon the loops 22, thus urging the Fig. 3 is a transverse section through a the building of the chimney indicated at 28,

having the usual opening therein-29, the

' sleeve 26 is also built into the chimney to have the spurs 27 extending into the'body of the chimney, thus holding the sleeve against displacement and allowing the same to present an even surface in engagement with which the retaining device may be seecured.

The thimble comprises, a neck 30 having an outstanding annular flange 31 thereon, while the inner endojf the thimble iscorrugated as indicated at 32. Thecorrugated portions 32 of the thimble are to be inserted into the sleeve. 26 and thus it will belnoted I k ,what v1E cl m-as en dtd s re t0 secu by.

that the inward movement of fil elthirnble; is limited by the flange 31' engaging the surface of the chimney 28. At this timethe e 30' ay b p a d ine ga me tivit c n of e p pe a? lamping ba d,

as hereinbefore described, placedinengagement, therewith, asl illust'rated in Fig.2,

However, before the ,connectionof a section ofgstove plpe therewith, the thimblejis connected to the sleeve by the device shown 7 inFigs. 2 and T. This device QQOI SiSts of a -turn buckle 33 carrying threaded stems 3,4. The semi-circular heads 35fare fixed upon, theouter ends of the, stems 34;: Theseheads are placed in engagement with the cor-rib gatedportion 32 of the thimble andthem the turn buckle 33 is rotated tocause the semi-circular heads. :35 to further bear with greater force upon the corrugated portions of the thimble, whichactionwill' tend to slightly-expand the corrugated portion to bring about a greater bindingaction in the sleeve and for this reason it is obvious the thimble will be positively held against any tendency of-accidental displacement;

In explaining the operation of the invention, it will be seen that the sleeve is placed in engagement with the chimney when the chimney is being built. It may be stated however, that if so desired, the present in vention can beusedi'n an ordinary flu'e' or chnnney opening without actually needing the sleeve.- The thimble may then be placed m-engagementwith the sleeve and the turn buckle adjusted to cause'the heads 35: to bear more-firmly upon the corrugated portion of the thimble to move-this corrugated portion lIltO' a firmer engagement with the; sleeve. A section of stove pipe may" then be placed in engagement with the thir'nble and in engagement with'each other and the clamping bands hereinbefore-described: may $1 21 be arrangedover'the joints of the sections for holding the same in firm engagement and also forming smoke tight joints.

From the foregoing description it will be seen that a very simple and efficient stove sembled condition, while the connection of the turn buckle arrangement will,positively hold the thimble in engagement with r the chimney, thus holding the device in condltion for use at all times.

Itis to bejunderstood that I may make such, changes in construction L and arrangement and combination of parts, materials, dimens ons, et .cetera, as may prove exp die tancl fa Wl l th SQQ-P 0f he pp. en 1ed.cl i uS- H vi a t s u y id sicrib ed my? nvent n,
