.whereby the spar-arm is. supported in ap- .proximate horizontal position. Thus the base member as a wholercomprises anelbow .and the inner: or distributingv arm 2.ofsaid a base;section.iwliich at its point of intersec- 'tion==,=with1 the.` leg hasli'secured vthereto a loopedwtie-rod 6, one stretch. 6 of which tierod extends: obliquely downward iand is securedl to the foot 3. by a retaining fboltt the same alsojserving to confine the spar sustaining: chair-iron he opposite-stretch loop for coupling..l connection with an `foblioluelydisposed truss-rod 8,- the same betheleg'Sand-foot 3. is an angle-iron trans- 'versely-disposed heelV bar 9, to the ends tof whichareadjustably secured toev strips 10, the adjustmentY of thefsame being eected by .'heelrfbolts 10-.1which are arranged :to engage any one of aseries of apertures in the toe-y strips. Theouteriendszof the toe strips v-10 are in turn securedito ends of across-arm 11, which latter is secured to the footf by a :retaining bolt 12 that -is selectively fitted into any oneof-a series of'bolt apertures 12 Aformed in the horizontally disposed webtof Vthe `footV 3', whereby the toe-strips may be adjusted and secured forwardly` or backwardly and, owing to thisadjnstable connec- `tion each toe-strip can be; independently shifted Yback and forth. i: By the adjustable arrangement just described the inner ends of the toe strips 10 may be arrangedto abut and conform to the circular contour of the silo whereby they serve .toresist load strainpupon theend-of. the spar:arm, as lclearly shown in Fig. 2.

, In order to; firmly vclampthe derrickspar arm l to windows having sills varying in width, I provide an adjustable sill-'clamping foot, 13, which foot is secured lto a clip bracket 14, ythatis slidablymounted upon the inwardly projecting distributerarm 2.

Thus it will be seen, asshown in Fig.`1,that' x thetoes of the Yfoot engage the: upper face -of' the sill and theinner sideface thereof lwhere;
