IMPROVED MIXING CHURN CONSTRUCTION. 



' I 'HE mi.xing of rubber compounds, owing to the heavy strain 

 ■*• of the stiff mass on the mixer, requires that this part of the 

 apparatus be very strongly constructed. The G. V. Scott Co.. 

 Brockton, Massachusetts, have made some important improve- 

 ments in this class of machines with this end in view. 



As the accompanying illustration shows, they build a churn that 

 is entirely self contained, the working parts of which, with their

bearings, are all above the tank. The strong, overhanging arm, 

 supports the whole weiglit of driving shaft, gearing and revolving 

 .-irnis, a socket at tlie bottom t f the tank serving to steady the 

 shaft against lateral movement , without, however, having to sus- 

 tain any of the weight. Two bearings support the shaft, one 

 on the end of the arm. immediately above the large bevel gear, 

 .-md one carried by the top of tlie tank immediately beneath the 

 gear, which is large toothed and very strongly cast. The ex- 

 treme upper end of the shaft is t'ltted with a screw adjustment, 

 by means of which any wear on the loose rings that carry the 

 weight can be easily taken up. The smaller bevelled gear is 

 keyed to the end of the driving shaft, which is also supported 

 liy two bearings and between these are the tight and loose 

 pulleys, the former keyed to the shaft. .Ml arms and gears are 

 secured by keys, in place of using set screws. These churns 

 are all made of one diameter (36 inches), but the height can 

 lie varied as desired when ordering.
