Therefore it becomes necessary to place the hook or screw into the wall at some distance away from the pipe. to stand out conspicuously and detract'from the appearance of the room. These common means usually employed to secure thesto've- V pipes are also usually unsafe; sincethe nails, etc., become loose, or the wire slips, letting the pipe slip out from the chimney. This would permit the flame to i nite the paper and cause a fire, or at least, a low smoke and soot to escape into the room. In addition to the advantages of this invention mentioned'above, the inconvenience of the stovepipe slipping too far into the chimney has been overcome. The pipe'can only enter the chimney now to the edge of the entrance of'the flue, and cannot enter to cut 01f the draft.

Practically no tools are needed toiinstall this contraption, and it can be done in minimum time, by inexperienced:personsyeven thougha fire is in the stove. It is practically impossible for the holder to become loose within the chimney, or for the wires to become loose. It has no nuts'or bolts to become loose, and it can be constructed at a nominal cost. 7 i f Briefly stated, the 'structureis characterized by a chimney clamp which hastheadditional function of a stop for limiting the inward movement of the elbow of the'stovepipe and which further functions 3 as an anchor and retention device for the retaining wire.

device will become more readily apparent from' thefollowing description and drawmgs.

'Figure 9 is a perspective view of the adjustable retaining element of the chimney p f l r f The primary part of the clamp generally designated by the reference character 10 in Figure 4 is of a composite structure within itself. For instance, it includes a part 11 in the nature of a chimney abutmentand this is of a cruciformconfiguration and includes a pair of outstanding horizontal arms 12 which engage the inner wall of the flue of the chimney, 13as seen in Figure 2. In addition there is a depending centralized finger, 14 which alsoengages the wall of the flue. Then too, there is an upstanding V-shaped part.15 having a'bent orhooked apex portion 16. This feature 16"constitutesa stop for limiting the inward sliding movement of the'portion 17 of the stove pipe generally represented at 18. f Thefinger 14; constitutes'a down-bent end orthe inner end o fthe stem 19. l? The longitudinal edge portions of this part 19" are formed with serrations 2O defining lon 'tudinally spaced keeperseats. At 21, in igure 6 is-a bent stop co-operating with the piv-' retaining detent 28 (see Figure 7) as shown.-

'- permits it to be dropped down to the desired oted latch 22. The latch is pivoted on the This detent is adapted to. permit the wire to pass therebeneath as indicatedin'Figure 6 to prevent accidental opening of the latch, In other words, after the latch is closed to the position seen in Figure 6, the wire is snap ed beneath the, detent or projection 28 t us holding the wire in 'place.

I now invite attention to numeral 29 in Figure 9, which designates'the adjustable part of the chimney clamp This is in the nature of a slide and includes atongue. 30 and a downbent flange 31 having a substantially T-shaped opening 32 formed therein. The restricted portion of this opening is adapted "to. be selectively dropped into the comple-' mental keeper seat 20. This permits bodily shifting and adjustment of the slide and then clamping position whereby, to hold the complete clamp in firm anchorage on the chimney as seen in'Figure 2. The clamp functions as stated, as a wire tightener as well as an an- Chorage device for the wire. a a

' The opposite end of the wire is associated with the continuously bent clip 33 (see Figure .3) in such a manner as to permit this end portion of the wire to be encircled or passed around the elbow as indicated at 34 in Fig ure 1; By thus passing the wire aroundthe elbow and then returning it through the guide eye 35 of the clip, then sending it through and connecting it with the apertures 2a in the latch,.tl1e,desired slack in the wire maybe taken up. 'Y

- Takefor example, the anchored right-hand end 25 of the wire in Figure 5, it will be seen thatby swinging the latch .23 over to. the

position represented in Figure 6 and snapping the wireunderneath of the head or projection 28, the'wire'will be caused to draw the end of the Stovepipe into the chimney to the point seen in F igure2. The pipe cannot enter the'chimney hole to block the passage for this is 5 prevented by the upstanding fea- 'tures15 and 16 (see Figure 4).

The ,gist of the invention, it will be observed, is in the provision of a structure char acterized by a chimney; clamp. This clamp comprises the structurerepresented F igured, and the complemental slide represented in Figure 9. The slide is adjusted to the position. represented in Figure 2, thereby and is associated with the especially bent clip 33. The clamp also has the additional function of providing bracing means for the clamp itself, as well as stop means for limiting the inward sliding movement of the branch -17 of the Stovepipe.

ltis thought that persons skilled in the art to which the'invention relates will be able to obtain a clear understanding of theinvention afterconsidering the description in connection with-the. dr wings, Therefore, a more lengthy description is regarded as un necessary. 1 e
