Similar numbers refer to similar parts through- Out the several views.
The drum I rotates freely around 8. These shafts 3 and 1 9 through sprocket Wheels The drum 6 is 1 turnmg in the bearings are dn'ven by a chain l or by a convenient gearing. The chain is driven through a speedreducing gear ll by the 13 properly counterpoi centricity of the drum I sliding of the bearings by a spring I 1 again grooves IB cut in the side of the drum l.
