The crosspiece 132 has a recess for receiving an H-shaped recess between its ends Toggle joint 138, which is pivotable at its lower end at 142 on the cross piece 132 and at its upper end at 144 is connected to an upper toggle joint 140. That Upper hinge 140 has a fixed pivot point on a pin 146 that fits into a hole 148 in guide plate 112 and extends into an opening 150 in a plague retainer 152. The retaining block 152 is on the underside of the Slide 38 attached.

The toggle joint assembly 138, 140 is straightened by a control rod 162 which has a generally rectangular bearing 160 which is received in the bifurcated upper end 158 of an arm 156 of the lower toggle joint 138. The control rod 162 extends rearwardly below the slide 38 and is mounted on a Tertikai extending pivot pin 164 (Figure 3) in the connection plate 58 at the end of the piston rod 56. A roller 166 is arranged on the rod 162 and moves in a limited manner Squat track 168 (Figs. 5 and 7) in a control block 170 attached to the underside of the “frame arms” 34. During the forward movement of the slide “Ton der Stellmng τβη figur 3 i” that clay figure 4, the arm 160 is pivoted through a small arc The toggle joint attachment 138, 140 is straightened by a lick roller 166. In this way, the toggle joint is straightened and the Qm & r piece 132 is relatively moved downwards. Since the cross member 132 is terbundcn with the vertically movable plate 126, this plate is also moved downwards and thus transports the upper cranial joint 90 and the L-shaped attachment bracket 118, on which the Sinspann-

The clamping fingers 124 extend see their Torae Slots 116 in the upper side lock 90 and have downwardly extending end portions 172 which "clamp the severed connection terminal" against the fixed terminal Seherbleek 92 serve (FIG. 9) »At their rear ends 174 the clamping fingers have rectangular recesses 176 to that with complementary sections 178 of the Shaft 122 in the mounting block 118 engage. The width of the indentations 176 in the clamping fingers 124 is slightly larger than that of sections 178 of shaft 122; the reasons for this are still explained. Si « Clamping fingers 124 are placed on the rectangular sections 178 of the shaft 122 is held by clamping plates 180 which are attached to the fiinter ends of the arms. You wave 122 is tensioned clockwise (in Figure 3} by a Coil spring 181 at the end of an arm 179, which see τοη one End of the shaft 122 extends, the other end of the spring is attached to a pin 183, the see τοη bucket Side of the plate 126 extends and the ends 172 of the clamping fingers 124 biases downward.

As shown in FIGS. 2 and 11 to 13, a coil 4 for receiving terminals 2 is clamped in a coil holder 26 which has a sheet 190 arranged on the base plate 28 and a recess 192 at its upper end for receiving the lower one Coil * flange 10. A spindle 196 is disposed in a vertical opening in the stern 190, and the upper end of the spindle has a reduced diameter portion with a conical tip which is shaped to extend into the recess 192 into it and enters the bobbin. The spindle 196 is biased upwards by spring force, but can be pressed down until the lower bobbin flange 10 is completely in the recess 192. On the right side of the block (in Figure 13) is a spring-loaded gate-biased stop 193, which acts against the band of the lower flange 10 and the flange against the opposite side 197 gate, so that the coil is precisely set in the recess and the holes 14 for receiving the terminals with respect a «f the slider are positioned accurately» Venn, a coil is properly positioned in the recess 192, electrical and hydraulic control means activated by means of a "pin 193 extending seitlieh the spindle τοη away by a slot 199 in the block 190 extends. The pin acts against a lever 200 which is pivotably arranged at its lower end 201 on the block 190 and is tensioned to the left (in FIG. 13) by a spring 204 which is attached to the lever and the block 190 At the top is the lever 200 at 202 with a notch Tersehen, so that during the downward movement of the spindle, the lever under the action of the spring 204 in one
