1. A rod of suitable length to reach the head wires, and 

 fitted with a hook at the top ; 



2. A slide that moves up and down the rod and can be 

 drawn, by means of a cord, up to the level of the head wire, 

 re-descending automatically, as soon as the knot is tied, into 

 the most convenient position for the user to attach the 

 training string without having to bend or stretch himself. 



On this slide is fixed — 



3. .The tying-machine (knotter). Fig. 61, composed of a 

 ■wooden fork to the upper end of which is attached the nickel- 

 plated tying mechanism consisting of three principal parts, 

 viz., the grip d, the lever e, and the locking plate h, against 

 which the grip is pressed by the lever after the training 

 string has been lapped. As can be seen from Fig. 62 the 

 string is caught and held fast by the grip d, and, as shown in 

 Fig. 63, is drawn down through the loops by the weight of 

 the machine in descending, thus forming the knot illustrated 

 in Fig. 64. 



The machine works in the following manner : the rod 

 being suspended from the head wire by means of the hook 

 at the top, and the tying mechanism being set at a height 

 convenient for the user, one end of the training string is 

 passed in a double loop over the two right-hand parts of 

 the grip, the short free end being then fixed tightly in the 

 metal piece h on the left of the grip so as to offer a certain 

 hold to the latter. 



Care is necessary to see that the end of the string lies on 

 the left side as shown in Fig. 61, whilst the right-hand loop 

 leads to the ball, which generally remains on the ground. 

 When the loops are made the slide is raised to the level of 

 the head wire D by means of the cord, the left-hand cord i 

 being then pulled to raise the lever so as to enable the grip 

 to catch hold of the short end of the string (see Fig. 63), 

 whereupon the machine is at once allowed . to drop, thus
