FOR AMERICAN VINES. 53 



setting up and dismantling are somewhat difficult, on account 

 of the weight of the pieces to be moved. To haul the 

 machine on the frame, the capstan is fixed to one end of it, the 

 cable fastened to the forecarriage of the engine, and worked 

 by hand ; it takes twenty minutes to mount in position ; the 

 setting up of the whole machine takes two hours. For shift- 

 ing ; the frame, capstan, and accessories are removed on an 

 ordinary dray. The weight of frame and capstan is 2 tons 

 8 cwt. Its cost, without either cable or plough, is 112. 

 With cable and plough, the plant costs 134 ; with small 

 extra winding drum, 176. The cost of the whole plant, with 

 an 8 H.P. engine, costing 240, is 392. With a fixed 

 pulley and the runner it reaches 416. 



PELOUS' STEAM WINDING DRUM. 



Resembles that just described, but has three interesting 

 additions.* First, it can work both ways ; second, the 

 winding of the cables is guided by a special device ; third, 

 the lateral displacement of the system is done auto- 

 matically, 



Description. As in the Guyot system, the engine and cap- 

 stan rest on a large strong frame made of rolled joist girders. 

 The capstan is double. That is to say, made of two drums, 

 each worked by a pair of cog-wheels. To each drum an 

 endless screw is geared, working a lever guiding the winding 

 of the cable. The throwing in or out of gear of the drum is 

 done by friction, which renders the throwing out of gear 

 easy whatever the traction effort be. It also serves as a 

 break during the unwinding. The large frame rests on four 

 rollers, rolling on iron rails ; two of them are geared with an 

 endless screw allowing their automatic displacement. On 

 the opposite headland a pulley is fixed to an automatic 

 anchor made of a truck travelling laterally, the stability of 

 which is secured by a case 141 cubic feet in capacity, which 

 is filled with earth. The lateral displacement of this truck 

 on the headland takes place on rails, and is obtained by 

 means of an endless screw and a cog-wheel ; one turn of the 

 screw corresponds to a displacement of 2 inches. 



The Bajac balance-plough, shown in Fig. 27, is used ; it is 

 made entirely of steel, and possesses great strength. 



The depth is obtained by means of two screws placed on 

 each side of the forecarriage. The frames of the two 

 ploughs are united together by a strong steel bar, which 

 renders the system very rigid. The beam can be displaced
