SPECIFICATION forming part of Letters Patent No. 732,596, dated June 30, 1903. Appnetnmned July 29,1902. seriainailmzv. (Numan.)
To all whom t may concern:
Be it known that I, CARL ANTON SPoERoNG, a subject of theKing of Sweden and Norway, and a resident of Stockholm, Sweden, have invented certain new and useful Improvements in Apparatus for Teaching Gun Practice, of which the following is a speciication.
Myv invention consists of further improvements in apparatus for teaching gun practice of the character described in my Patent No. 707,729, dated August 26, 1902. h
The object of my invention lis-to provide improved means whereby the practical opera-l tions of target-shooting may, so far as the drill exercise is concerned, be carried on without the waste of ammunition and ,the dan-- gers 'incident thereto and also without the long range necessary to the common practice.
The invention comprises, essentially, a universally-jointed gun-support, which gun may be a dummy or false gun and is subject while on said support to the manipulations of the practitioner, said support allowing practically the same deviations of the gun when being sighted asin the common practice, With means for transmitting the deviations to a pointer so connected to the gun-support as to keep in such alinementfrelatively to the line of the gun-sight as to point to the same object, and a clamping device which is automatically actuated simultaneously with and is set in operation by the pulling of the trigger and instantly locks all the parts fast in the positions they occupy against movements in any direction at the instant the trigger is pulled, so that the pointershows with rela 'tion to a iixed center representing the bullseye of the target the deviations due to the practice of the unskilled operator as they are shown on the ordinary target, as hereinafter described, reference bein g made to the accompanying drawings, in which- Figure lis a vertical section ofthe apparatus without the gun, the section being taken in a plane at right angles to the vertical plane of the gun. Fig. 2 is a vertical section of the apparatus in the plane of the gun and side view of the gun mounted thereon with a part` of the gun broken out. Fig. 3 is mainly a horizontal section of the apparatus in the plane of the universal axes of vibration of the gun-support. Fig.` 4 is a horizontal section showing a modification of the clamp. Fig. 5 is a detail showing the clamp setting and tripping lever. Fig. 6 is a detail showing the trigger fixed 011 the gun-support, as it may be When a dummy gun is used.V
A represents the gun, and a represents a support of trough-like construction in which the gun may be placed, so as to begripped together with the gun by the left hand, as the ordinary gun is gripped when placed against the shoulder for use, While the right hand grips the part Z only of the stock ofthe gun. The gun is temporarily secured in the support a, by a couple of tap-screws d2, for which suitable holes have to be tapped in the un`- der side of the gun. The support a is at its rear end mounted on the topk of a vertical pivot-standard b, which atabout the middle of its length has a support in a clamp c, through which it is iitted so as to rotate, said clamp being carried by trunnion-pivotsd in housings e, set upright on abase-plate r, so that the support may shiftin a vertical plane for adjustment as to elevation of the trajectory, While rotation of standard horizontally accommodates the lateral range. The clamp c carries a step-bearing f for the pivot g of the lower end ofthe standard b, said bearing being suspended a suitable distance beloW by hangers 72. The gun is thus mounted so as to work universally in the hands of the operator practically the same as a gun wholly supported in the hands, and with the gun so mounted a pointer t', located below and preferably to the left hand of the guny and universally pivot-jointed atj, is coupled to the standard b, so that the pointer automatically follows the line'of the gun-sightin all the deviations it may make when manipulated by the operator, and when the gun is accuratelyv i pointed with relation to the object aimed at the said pointer registers with a bulls-eyel viation there may be of the pointer relatively to this mark represents the measure of the inaccuracy of the operator. The connection IOO of the pointer-stad 't' with the standard bis j preferably by means of a metallic strip or wire spring l2, having several coils 13 and a I er .l
rigid arm 14 interposed between said spring and the stai for an elastic connection; but this may be modified at will. The universal fulcrum-joint pivot of the pointer-staff i may be constructed in any approved way. It is to be understood that the pointer is not necessarily located below nor to one side of the vertical plane of the gun. In regard to these particulars the arrangements specified are only such as preferred. To iixedly set the pointer exactlyin the position occupied at the instant of pulling the trigger and retain it a short time for observation, the trigger n is made to release an automatic clamp, which at once rigidly arrests all movements of the gunsupporting apparatus, and thus rigidly sets the pointer ih whatever relation it may be to the bulls-eye mark. The clamp, which is of a duplex character, may be constructed in various ways, and I do not limit myself to any particular construction. The construction which I represent herein as one example of such devices suitable for carrying out my invention consists of the housings e, between which two clamp-jaws care pivoted, said housings being made slightly elastic in their supporting parts e', and the flange p of the internally-screw-threaded sleeve q, placed outside of one of the housings and coupled together v Vby bolts s, extending through slots t of the clamp-jaws c, allowing said clamp-jaws limited rotatory movement on their axes without hindrance by said bolts, said housings being also free for slight movement along the bolts, or at least the one between the iiange p and the block c must be so. In the sleeve q is a clamp-operating screw u, to one end of which, projecting from the outer end of the sleeve, a hand-lever 'v is attached, while the inner end of said screw has when screwed up contact with the housing e, against which the flange p of the sleeve q bears. The lever c carries a ratchet-segment w on the extremity of its short arm, which engages with a pawl :r when the lever is turned by hand to the left or in the direction to retract the screw and holds it for maintaining the relaxed condition of the clamp. On the sleeve q between flange p and a collar y is a coiled spring a', one end of which is secured to flange p at 2 and the other end engages the short arm ot' lever QJ at 3, said spring being so adjusted that under tension it thrusts the lever so as to tighten the clamp when ratchet w is released from the retaining pawl-bit x. This pawl-bit is carried on a lever 4, pivoted at 5 and having a spring 6 normally keeping the said bit in engagement with the ratchet w. The lever 4 reaches into a recess 7 in the standard just above the step-bearing of said standard, so that a rod 8, set upright in the hollow axis of the standard, may rest at its lower end on or slightly above the lever 4 near its free end. This rod extends upward to the top of the standard b, or thereabout, where the arm 9 of the trigger 'n rests on it above a perforation l0 made through the trigger-guard plate for the rod, so that when the trigger is pulled lever 4 is depressed, which releases pa'wl-bit w from the ratchet fw, allowing spring z to act and tighten the clamp at the instant the trigger is pulled, and thus lixedly set the pointer in the relation to the bulls-eye 7c that thegunsight bears to the object aimed at, which may be any object at a suitable distance or a common target, if desired. The jaws c clamp the standard b and x the pointer relatively to horizontal range, and the housings clamp the jaws c and tix the pointer relatively to vertical range. The lever 4 carries a plate 21, the breadth of which is coextensive with the lateral range of the end of the rod 8 due to the oscillations of the clamp c on its trunnions, and thus insures uninterrupted connection of the two notwithstanding the oscillations. The spring 6 and lever 4 return the rod S to bearing contact with the trigger-arm 9. The lever fu is pulled forward again and is automatically again engaged by the pawl-bit a: for releasing the clamp preparatory to the next operation.
The base-plate r is detachably and adjustably clamped to an arm 14, which is similarly clamped to a post 15, that may have any suitable support.
A protective inclosing case 16 is applied to the apparatus below the support ct, and a funnel-shaped protector 17 for the pointer z' is suitably attached to a post 11 of said base and carries at its larger end the before-mentioned transparent support m, through which the vpointer t', indicating the results of the efforts ofthe practitioners, is seen, the range of said funnel being such that the operator has the mark 7c and the pointer in his visual range after firing the gun, thus enabling him to observe the result of his eorts without removing from the position he occupies when manipulating the gun.
As one modication of the clamp, a solid block c is represented in lieu of the jaws c in Fig. 4 with a thrust-pin c2 fitted in suitable perforations of the housings e and the side of said block intermediate of support a and the screw fu, to thrust against the side of support a directly for clamping said support against rotation. Thus the clamp is not limited to suchjaws c. When the jaws c are used for clamping the support ct against rotation, the hangers h, by which the step-bearingfis suspended from said jaws, are divided in the upper part, as shown at h', Figs. 2 and 3, to allow them to spring suiiiciently for clamping said support.
In Fig. 6 the support a3 is more particularly adapted for a dummy gun, and the trigger n is mounted on said support, as it may be, if preferred.
What I claim as my invention is 1. The combination of the universallymovable gun-support adapted for the application of a gun in connection with it as in sighting the gun and shooting, a gun mounted thereon, a pointer having a universally- IOO IIO
-jointed .support and connected with the gunvadapted for the application of a gun for use in` connection with it as in sighting the gun and' shooting, a gun mounted thereon, the
' universally-jointed mounting of said support,
a pointei` having a universally-jointed snpport, and connected with the gun-support so as to maintain parallelism with the deviating line of the gun-sight, a bnlls-eye mark located in the line which the pointer occupies when the gun is truly sighted with relation to the object aimed at, the range of said pointer and mark being such that .the operator has them in his visual range when in the position for operating the gun, an automatic clamp to lock the parts-in the positions 0ccupied when the trigger is pulled, setting devices for holding the clamp in readiness for 3o action, and tripping mechanism for said holding devices actuated by the vgun-trigger.
