A similar ad- '55 v'ational view showing a portion of the chimney ju'sting and retention nut 21 onthe threaded rod cooperates with the slide 24 to regulate its position. A pair of shorter links 28 are pivoted to the intermediate portions of the links 25 and function as a toggle unit. The lower ends of the adjusting and supporting links 25 are pivotally connected, with diametrically opposed clips, these being shaped to engage over the pipe 29. The vclips are. employed in'pairs denoted by the numeral .30 and aresecured by bolts or the like'sl to the pipe.

It will be noticed that "the-screw-threaded rod is provided with vertically spaced holes 32 to accommodate locking pins 33 and 34, the upper pin 33 coacting with the bracket. l2 and the. e lower pin 34 coacting with the slide 23. The pins can be placed in the desired holes. 32ydepending on the size of the pipe ongwhich the fixture 20 is adapted to be mounted. Obviously, the pin 33 servestointerconnect the hood and spindle to maintain the parts assembled. The toggle and nut arrangement serves to-adj ust-tlie links 25 to, in turn, adjust the clipstll to adapt the fixture 20 to the chimney pipe 29;" Consequently, this device is suitable for pipes of Varying diameters.

Somewhatthe same generic arrangementvis shown in the modification in Figures 6 to"-9.- Here the rod 35 has its upper end formed into a spindle 36 provided with an assembling pin 31.; A plate is, disposed between the' binding nuts 38 and 39 and providesa support for the hingedly mounted links 40. The links 40 are pivotally attached as at '4l toUeshaped clips 42 which "saddle over the pipe 29, being attachedthereto' by suitable fastening 43. The plate 40a accommof dates the slotted pendant 44, this serving to accommodate a boltand wing nut assembly 45 to regulate the toggle links 46 The toggle links are pivotally attached to the intermediate. por

It is thought that the description taken in? connectionwith the drawings will enable a clear understanding of theinvention to be had. Therefore, a more lengthy description is thought-un fy necessary.
