Coupling for targets, in particular fail targets.

Patented in the German Empire on November 17, 1909.

The invention relates to a coupling for target targets, in particular for drop targets, and consists essentially in the fact that one of two coupling elements is the disk rigid, the other connects it resiliently to the drive shaft and the rigid connection while erecting the disc. is canceled, so that only the yielding The clutch remains engaged and the disc

“O can be knocked over by the bullet.

One embodiment of the device is shown on the drawing. Fig. Ι is an elevation of the device with the housing attached, FIG. 2 shows an end view of the coupling between the disk carrier and the oscillating shaft, FIG. 3 shows a longitudinal section of the coupling 4-4 of FIG. 2, FIG. 4 shows a cross-section according to 5-5 of FIG. 3 and FIG. 5 shows a cross-section according to 6-6 of Fig. 3.

ao The disc carriers F are removably attached in a hole in the pieces α (Fig. 1). The piece α carries a pin a ¹ , which faces the bore for the disk carrier F axially (Fig. 4 and 5). On the pin a ¹ a sleeve b is set, which carries two latches c and d in one approach (Fig. 2 to 5). The bushing b carries in its bore an annular extension b ¹ , against which the head of a screw b ² engaging in the pin a ¹ rests (FIG. 2). The end of the sleeve δ is slightly drawn in and engages around one of the slotted ends of the shaft C (Fig. 1). A pin & ^s (Fig. 1 and 2) is struck through the end of the sleeve b and the slot so that the sleeve b is firmly coupled to the shaft C. On the other hand, however, the sleeve b on the J pin rt ^{1 can} twist against the piece α ', as far as this allows the latches c and d . The screw b serves to prevent longitudinal displacement of the piece α against the sleeve b .

The bolts c and d are urged against the piece α by springs c, the tension of which can be regulated by screw pins h and nuts i (Fig. 3). The end of the Ric * - ■ '45 gel c engages in a hole / of the piece a. and thus locks bushing b and thus also shaft C against piece a. The locking is released by the fact that, when the housing b rotates about its axis, a pin / attached to the bolt c, which ^{slides in a slot & 5 of} the sleeve b , strikes against the fixed cam piece / e, whereby the bolt c from the hole f is pulled (Fig. i).

The bolt d tapers in a wedge shape and engages in a correspondingly shaped incision g of the piece α . It is secured against rotation by a pin d ¹ which slides in a slot & ^{4 in} the bushing '.. &. When the bolt <x is in the hole f , the stop p of the sleeve b is in engagement with the stop 0 of the piece a (Fig. 2). The stops 0 and p make it possible to flip the pane even if it has not been hit, which can sometimes be desirable. The engagement of the pin g in the groove of the piece α does not appear to be reliable enough to necessarily turn the disk over from the shaft C , so the stops 0, p are also provided as a backup. If the disk is to be turned over, ie from the position in FIG. 4 to that in FIG. 2, then shaft C

turned to the right, and the stop /> takes the means of the stopper a segment ο with and brings it into the position of FIG. 2. The piece carries two additional α, suitably adjustable stops in and n, which in the two end positions of the disk Hit against the lugs / the base plate. When the disc is upright (dash-dotted position F ¹ in Fig. 4), so is the Bar c through the curve piece k under 'Vor-. middle of the pin / excavated from the hole f , and only the engagement of the bolt d with the notch g holds the disc upright. The pressure of the spring e of this bolt must be such that the wind does not overturn the disc, but that, if it is hit by a bullet, the bolt d pops out of the notch g so that the piece α is opposite the sleeve b can rotate until the disc so in the dash-dotted position of FIG. The piece α has a groove q (Figs. 2, 4 and 5) in which the end of the bolt rf can move freely over the surface of the piece α after it has jumped out of the notch g . If, in the position of the parts according to FIG. 5, the disk is to be erected again, the shaft C must rotate the bushing b to the right from the position of FIG. 5 into the position of FIG. 2 until the stops 0, p again come into engagement and the latches c, d fall back into the associated recesses. The parts α and b are now coupled again by the bolt c, and the shaft C can erect the disc. Shortly before it is fully erected, the pin j strikes against the curve piece k, and the bolt c is lifted out of the hole f. The living force of the straightening pane supports the bolt rf, which now has to hold the pane on its own. Ρλτεν τ-claim ε: ■ ι. Clutch for targets, esp Drop discs, characterized in that between the disc holder and the drive shaft two locks are provided, one of which the disc holder is flexible, whose other makes him immobile with the drive shaft connects, and that during the erection of the disc the non-compliant Clutch is automatically disengaged, so that the disc only from the yielding Clutch is held, 2. Coupling according to claim 1, characterized in that two bolts (c, d) are mounted in a bushing (b) coupled to the shaft (C ) in such a way that they rotate with the shaft (C) and when the disk is overturned the influence of a spring (e) into a bore (f and g) of a piece (a) receiving the disc holder to straighten the disc, while during the rubbing -.
