I Patented Dec. 5, 1932 I mark the hits'by projecting j Unirse STATES] 'PATENT OTIO ASTLZ, OF BERLIN, GERMANY DUMKY appueauua mea :man ao, 1931, serial n.

Firing practice weapons are known which a light and shadow picture, the projection in one type of tiring practice weapon being effected from within or beside the barrel, so that the di rection. of the rays follows the` movement of the barrel; in another type therelativcly movable intersection of the ra s with the aiming device is rendered possi'le in that the. barrel of a dummy rifle or piston is'morablyl mounted on the projection apparatus, so. that the-marked hit in the lprojection apparatus time without subsequent physiological effects light shines two lilms or transparent discs are 'positively follovs the straight line movements of the rear part ofthe aiming device.

The fundamental idea is with a dummy rifle or'pistol to 'allow the hit to appear on a target surface. for an unlimited length of to the eye and also without the movable t` ting hitherto necessary on a projection apparatusand is characterized in that in the oarrel of the dummy throughl which a searcharranged, the target lm being oscillatahly suspended in a pendulum holding the balance, whereasuponv the trigger ,being pulled, the hit lm mounted onr a hinge fixes the target disc vin 'the' position in which it is actually situated when the .trigger is pulled. This arrangement of the dummy hre arm presents the advantage over the known firing practice weapons that both the target lm and the hit film can be arranged the one on theotherin the barrel,`the hit position being dependent upon sure aiming and keeping steady as with a real firearm, because the bullsfeye of the target before thepulling of the trigger reprel of which carries ,the target lm zbvmeans 'box tends topullthis bar towards the butt 'jupon the ltrigger is p an La 525,427, and in tie-:14e: opmaam, lese.

In the rear portion of .the -harrel'an electric l bulb e, provided with a switch c and current 55' leadrl, is inserted. An asbestos layer g can. be' placed around a bulb cover f which is' nickel-platedon the inner side. The asbestos FFICE j' i' layer serves .for preventing the radiation 9i heat- L be middle portion ofthe ban-e1' 'aj l ,double jailed bored iframeA h is arranged,

A transparent hit ilm n, hinged on the lower end of the target :frame hand having an opaque point in its centre, has a. lever o intothelockbox. e .i

In the lock box a bar p is slidably mount-- ed and a spring pvixe'd at. one end to the bar' p and at the other end to the wall of the loci:-

of the ride, 'A spring p'is mountedat an ineline on the bar p and-undery the lever p of the hit film n.

' For bringing the rifle into xing.coxtxdition the bar p is pulled towards the muzzle of thev ritie lby means of a lmob projecting through a slot in the bottom 'of the lock box, thus tem. sioning the Aspring r. *The bar p :is heldin its forward position lay-means of a short hook ,extending thmughfhe wan gf uw bami a 7s of a spring-controlled trigger a, which en. :a

During. the aiming, the target lm s' oscillates in accordance with the movements o'f` h`-` thezrie and lwhen proper aim has been taken c: f andfhesighisminaugmemwahmbank L kf eye of the projected target, the bulls eye of the target. film is situated in the axis of the bore.

Yfhen prcure is exerted on the trigger, the hooi: is disengaged from the holein' the .bar p so that the bar p is suddenly pulled towards the butt of the rifle by means of the spring causing the spring p1 to bear against A position, it will show onthe projected picture the actual position of the .axis of the bore at Vthe.instant when the trigger was pulled and thus indicate the accuracy of the aim.

The rifle can also' be constructed so that itV operates only after the insertion of a coin'.

For this purpose a slot V is provided behind' the breach o'- the rifle `and the butt b made hollow toorm fa coin collecting receptacle XV.' The end of the har p projects towards the rear beyond this Slot V and has an apex.. I' i-inpact so that said Saul-ce of light projects u ture for the, passage of alcoinand at its extremity a stop for holding' the coin after 1nsertion. On the under side of the butt opposite the slot V a rocker lever u is arranged which in' normal" position', that'is before the insertion of a coin, assumes a position behind trie trigger s and prevents sam., from oscillating,.so that the rifle cannot be used. i Y If a c oin t isinserted in the slot V it passes through the aperture in the endv of the' bar p and bears against therear arm of the rocker lever u causing this lever to rock so that its other arm is lifted sufliciently to allow the `trigger sto be actuated. In oscillating` the tri ger a bears against thefront arm of the roc er lever u which presses against and slightly raises the rear end of the bar so that the coin stop libc-rates the coin w 'ch runs into the `collecting receptacle W.

I claim l v i. A dummy ria, comprising in com-nination with the han-el of the rifle,A a source of light arranged in the rear end of said barrel, a double-.walled frame having a central bore fixed in said barrel in front of said source of light, 4a. carrier on said frame projecting to wards the muzzle of said barre a ringshaped pendulum on said carrier adapted to oscill'ate relative to 4said carrier and retain its vertical position as said barrel is inclined, an arm on said pendulum extending towards the rear of said barrel, a target film su ded on 4the rear end of said arm and vertically uided in saiddouble frame lint capableoi atei-al displacement when said barrel is turned to the right or to the letz-a condenser- Lesiones lens shiitahle in the front end of said'liarrcl V adapted in conjunction ith saidsoiirce of said target film adapted through the intci- 7n mediary of said arm and said pendulumto oscillate in any direcLon relative to said bar rel so that lien said barrel is in horizontal position, the centre o said target film coin-- i cides with the centre of said barrel.

2. A dummy ride as specified in claim 1, comprising' in combination with the rifle barrel, the targetY film. the double milled frame, the source of light and the lock vbox of the rifle, a transparent hit film having an opaque point in its centre hingedly mounted on the lower end of the rear wall of said frame, a 'lever extending from said hit lilm through the wall of said barrel into said lock box, a shiftable har iii-said lock box, a pull springin said lock Ibox` connected to said lock box and to said shiftable bar adapted to sud- A denly pull said barton-artis the rear, and un inclined spring on said bar adapted to henragainst said lever to cillate and bring said transparenthit filin against said ring target with its opaque point in the contre o f the barrel bore and to hold said target film in the l osition it actually occupies at the instant of the picture of said target film with the centre point of said transparent hit film indicating the 'position of the target relative to the centre oftiiebai'rel.V
