rope. Another rope is passed over anotherl 

 pully in blocks, 1, and 3, one end of which is 

 attached to the axle ot'the wheel 4, and a hook 

 to the other end of the rope. A third rope is 

 pissed over the other pully in block 3, and is 

 also connected to the axle of a hook as afore- 

 said. These hooks descend far enough to be 

 attached to the wagon body ; these over 2, 

 and 3 to the ends of it, rather farther from 

 the centre of the floor than the middle 

 of the load. The rope descending from 1, to 

 the side of the load next to the centre of the; 

 floor, is passed under the load and attached toi 

 the other side of the wagon body. Another' 

 rope is made to uncoil from the wheel while 

 the three aforesaid coil upon the axle of it, by 

 means of a horse or other power, attached to, 

 the rope which is upon the wheel, and madei 



to move from the building, (drawing the rope 

 under the friction pully 5, at or near the 

 lower end of the road-way,) a sufficient dis- 

 tance for the load to be discharged over the 

 tie M, M, into the bay, when a sn>all down- 

 ward force is applied by the hand of a person 

 to raise the rope at the under side of the load, 

 and thereby cause it to make part of a revo- 

 lution sufficient to cause the load to fall intu 

 the bay, the hooks at the ends of the load 

 serving as a pulleman. 



By shifting the machine, the opposite bay 

 can be filled or other floors used in like man- 

 ner. 



The wagon body can be attached and de- 

 tached to and from the running gears in a 

 few seconds, by means of screw or spring' 

 bolts.
