Abstract

15,500. Mitchell, F. Aug. 17, 1907. Rifle practice, teaching.-In target - practice apparatus in which the aim is recorded by indicating-mechanism such as a pointer or needle and a miniature target, the parts of the mechanism carried by the gun and by the stand are not brought into engagement until the firing action takes place. Thus the aiming movements made by the gun are not followed by the indicator. The two parts between which engagement is made on firing may take the form of a conical recess and a point, so that if the aim is not accurate one of them is deflected. In the constructional form shown in Fig. 1, the conical recess F<2> is in the indicating-needle F, and the point G' is carried by the gun. The needle F and sub-target H are both mounted on a stand B of the kind described in Specification No. 2883, A.D. 1907, in such a manner that on the firing action taking place, the needle and target move forwards together until the needle is deflected and stopped by the pin G'. The target then continues its forward movement alone on to the point of the needle. These results are attained by mounting the target at the rear end of a sliding spring- controlled tube D, and mounting the needle at the forward end of a tube E telescoping in the outer tube D and normally pressed forwards by a spring D<2>, The outer tube D is connected to the firing-pin by a wire A<2>. Various modifications are described of the mechanism for obtaining relative movement between the target and needle. Modifications are also described in which the needle and sub-target are carried by the gun, and in which the conical recess, instead of being in the needle, is on the other part. The invention may be employed in conjunction with a firing limit device such as described in the concurrent Specification No. 18,638, A.D. 1907. In the form shown in Fig. 5, a needle R co-operates with a plate R<4> forming a combined indicator and firing limit device. Specification No. 9977, A.D. 1906, is also referred to
