off the work site while remaining intact i e as a whole unit without being partially disassembled a separate jack 194 will be similarly mounted to each end however when it is desirable to separate or divide the apparatus into two halves an additional configuration 10a as shown in fig1 is employed specifically when the equipment is halved dolly wheel configuration 10 is used on one end of a half section and configuration 10a fig1 is mounted on the opposite connecting end of that half section the other half section would be configured in a like manner both would be moved to a new work area and the equipment sections would be joined after disassociating the dolly jacks 10 and 10a with reference to fig1 the arrangement 10a is connected intermediate the finishing blade length where there are no hydraulic level control mechanisms 20 the connecting bracket 170 for apex pipe 50 is comprised of two sleeve halves 170a and 170b fastened together with suitable mounting bolts 191 and nuts 192 to lift the mechanism set screws 163 hold the inserting frame members 190a of the dolly jacks 194 captive within sleeves 170c and 170d tool mounting bracket 171 comprises stanchions 167 and 168 projecting downwardly to support brace 169 that is placed in position beneath the blade to support it columns 167 and 168 are welded to horizontally oriented sleeves 165 and 166 the sleeves are equipped with set screws 163 for holding the inserted frame member 190a in a fixed rigid position the frame members 190a project through sleeves 165 166 into sleeves 170c and 170d at the middle of the apparatus additionally tubular bosses 174 being threaded at each end are held captive between screed 30 and.
