In some instances the cantilever planis adopted and a beam Is connected withbolts to the projecting beam at the top,while the lower end of the beam is sunkinto a recess made in the wall. Thisbeam, B, affords an effective bracing, ifthe beam is correctly attached. Sometimes the bolts used for joiningthe upper end of the brace to the extend-ing beam are not strong and pull have seen quite odd patterns made ofwrought iron for purposes of bracing abeam, one of which is shown in Figure the wrought iron work is made by thelocal smith, and if this man is experi-. enced in such work and makes a goodconnection with powerful strappings ofwrought iron, the chances are that quitea strong bracing will result. But if anyold metal bracket bracing is screwed tothe parts, the heavy weight applied isvery liable to loosen the connections andpull the rigging down. Then, there isthe mode of bracing exhibited in Fig-ure 4. This involves a system of placingwooden braces from the base of the ex-tended beam to the recesses made in thewall as shown. It is possible to acquirevery effective supports in this way. There are no bolts to slip. The bracesare furnished in wood that will not spring when there is a heavy strain onthe beam. You can get quite a stronglever by this plan. Still another style for fixing up a beamfor hoisting purposes is shown in Fig-ure 4. This plan requires a brace for thelower part of the beam on the outside of
