DEANE'S SILK REEL. 



The furnace ^.— The boiler B.— The filaments first pass the guides C, each thread by 

 itself,— they then converge and pass the guide D together. Both divisions are then wound 

 u;->on each sufficiently to insure firmness, roundness, and smoothness of thread, and they 

 then separate, eacli one passing its appropriate guide E, and is then gathered upon the 

 reel. Jt is spread upon the reel l>y a vibrating movement of the rod F, having its fulcrum 

 at a, the alternaling movement being given by a groove in the shaft of the pulley wheel at 

 b. This groove receives a pin from the vibrating rod. The skeins are disengaged in the 

 following manner: The two arms of one division of the reel are set inside of the other, and 

 slip through a mortice in the shaft of the reel, and are retained by two keys driven at right 

 angles with the arms. By starting these keys, the arms slip through the mortices, and the 

 tension of the skein is at once relieved — To lay out the groove, proceed in this wise : At 

 one of the limits of the intended groove stick a pin; then just half round the shaft at the 

 other limit stick another. A straight line from one pin to the other, and back again on the 

 opposi'.e side, is the track for the groove. — 'I'he guides should be made of brass or German 

 silver, by drilling a fine hole and sawing a slit to it, all made perfectly smooth. German 

 silver neither rusts nor corrodes. James Deane.
