IMPERIAL

PATENT OFFICE.

The present invention relates to a device for monitoring the removal during Wrong. It forms an embodiment of that protected under patent no Device and allows even the slightest movement of the archer's right index finger visibly detect it during removal. Even an inexperienced crooked teacher becomes This enables you to observe precisely whether the shooter pulls off properly or rip through. In most cases, the rip-through is followed by a quick snap of the finger. The apparatus prevents this; any hasty forward movement is as good as impossible, and precisely these movements lay the seed for the formation of restless, unpredictable achievements Protection.

The device enables the instructor to move the right index finger of the shooter can be followed clearly and any errors can be identified immediately with ease. Here is the Protect in the independence of the bending is not hindered, a ripening under However, a decrease in the pressure point is impossible.

A large number of people find it difficult to disregard the rules of the goal and especially to get a picture of the value of slow contraction; with the help of Apparatus, however, this is made easy to understand even to really limited people can be. By virtue of its simplicity, its design is likely to make the device of be able to be used with success by any training personnel; she can go to anyone Target exercise can be conveniently taken along.

The device is shown in the accompanying drawings.

Fig. Ι is a top view in a loose position,

Fig. 2 is a top view in the tensioned position,

Fig. 3 is a side view in loose and

4 shows a side view in the tensioned position;

Figure 5 shows the device in action.

It consists of a leg a, which is placed on the left wall of the box in such a way that the retaining pin g engages in the hole for the clip pin. Thereupon an with a respectively. its right-angled extension a ^l , the shorter leg b connected by a hinge c , is folded over onto the right box wall, in which position it is held in place by the retaining spring / screwed onto it. The latter acts to increase its spring force on a nose d attached to the hinge c.

The leg α carries the hollow cylinder h, as well as two retaining springs p ¹ and p ' ^{2 which are} screwed on along the same and which surround it upwards halfway . The hollow cylinder h accommodates a narrower hollow cylinder I. A helical spring 0 is active in both, which allows the narrower hollow cylinder / to slide back and forth in the wider h. For guiding the narrower Hohlcylinders / is used mounted on him up in the Längsnuth i further Hohlcylinders h and m slide on guide pin. By the α on the leg holding screwed

spring ρ ¹ the guide pin m is pressed when stepping back the narrower hollow cylinder / into the detent k and held here; while the retaining spring p- prevents the hollow cylinder / from sliding out completely, it also serves to indicate the movement of the hollow cylinder / on the graduation on the latter.

The outer end of the hollow cylinder / is closed by a round plate or disk, which carries a curved abutment η on the right side (Fig. I). This occurs when using the device, driven by the coil spring ο, against the nail of the right index finger of the shooter.

Claims (1)

Patent claim: An embodiment of the device protected by patent no. 70170 for monitoring the pulling during leaning, characterized in that the abutment (s) is pressed from the front against the index finger by a spring (0) and its movement is on the shaft (I. ) allows to recognize the attached graduation. 1 sheet of drawings.
