Field Made Hoist. A" ordinary mason's hoist has 

 been converted into a concrete elevator by a rocking 

 cradle as shown in the accompanying sketch. This is 

 framed out of any timber on the job, and will prove a 

 handy outfit. A vertical wire, run through an auger 

 hole in the end with a stop on it at the proper 

 height will dump the cradle where you want it. Any 

 shoulder or attachment would do the same. Use a 

 hopper up above as on ordinary work.
