Fig. 49. Diagrammatic section of same. 



In Bajac's gin (Agricultural Show of 1892), shown in Figs. 

 48 and 49, and Plate II., the large cog-wheel A connected with 

 the pole B, can be clamped to the drum D by means of 

 two pins c. The hauling-back cable winds on the groove 

 of the pulley E connected with the pinion F, which 

 engages the cog-wheel A, when the drum is thrown out of 

 gear ; the pinion F is worked by a lever shown in Fig. 48, 

 in which may also be noticed the pawl clicking with a 

 ratchet on the top flange during the work. When the 

 plough reaches the end of a furrow the drum d is released, 

 the pulley E thrown into gear, the hauling back cable 

 passing over the fixed pulley and winding round it, pulls the 

 plough back to the start ; the horses always turn in the 

 same direction. According to the stiffness of the soil, the 

 diameter of the drum may be increased by wooden sectors, 

 as shown in Fig. 49. 



The whole mechanism is carried in a strong frame, travel- 

 ling on four discs with a sharp edge, penetrating the soil, as 

 shown in Fig. 49, or by rollers on rails (Fig. 48).
