Description

A PRACTICE DEVIOE FOR USE IN AIMING The present invention relates to an ement for use n so called a fixed visor arrangement comprising a target which is controllable from a distance by the person aiming at During the training of recruits or beginners so as to these persons engage in aiming practice One o these practices is the so called In practice the is sand bag or whatever other fixed support and may be held in such The recruit looks across the sights unto a white target sheet in front which a helper holds target This target disc has a long handle and is composed of a round metal sheet of about 10 diameter and which has in its center a black painted bulls eye and a small hole through which a marking pencil can aimin recruit indicates by signs or by calls to helper that the latter has to shi t the target disc to the other u or As soon as the recruit is of the opinion that the bulls is in the line of he causes the helper to mark the point by means of pencil passed through hol in the bulls thereby markin a point or other sign on white sheet behind the target This is repeated three the three points since the position of the rifle has not only in very rare cases the coincidence of the three points is actually the points three triangle which can by between three the the triangle the better is th aiming capacity of the there is possibility to classify the recruits in accordance their capacity to properly aim at the Moreove it is thus possible to visually progress of a recruit without expending expensive ammunition for this it a disadvantage o angement that apart from the ructor who is able to supervise several required for every the recruits and this means a large expenditure of working But even trained personnel it might happen that target discs are slightly shifted while passin the pencil through the hole in the center thereof and thus the so obtained triangles might not indicate true conditions of a has become a ment for instruction of wherein a target sheet on which a target has been indicated is shifted by the recruit himself with the aid of pulling cords to one or the other direction until he believes the target to be in line of the By means of another pull rope the recruit can himself operate a marking element which latter records the results of the aiming on a separate strip of This arrangement suffers from the that even not less personnel is needed since after every aiming target sheet has to be shifted manually which cannot be by the recruit himself since results obtained by him must necessarily Furthermore the operation of the pull ropes makes it impossible for the recruit to aim The subject matter o the present invention an arrangement for wherein the above mentioned disadvantages are eliminated thereby that the target is constituted by a target disc which is movable in front of a target the disc being in a conventional way an opening in its center for marking the point aimed a moving being provided comprising extending in parallel vertical planes the two rails being to one the aaid disc bein movable along one of the said rails and this latter along the second screw threaded spindle being coordinated in each of the said rails so as to serve as a means for effecting the thereof thereby that a nut screwed onto each of spindles is connected with said rails and the spindles are turnable by means of electromotors controllable by the person that to say is o advantage i there provided on the target disc an arrangement for marking which arrangement is operable by the aiming person as soon as latter has decided a fixed point in the target and wishes to the center of the target disc in relation to the target It advis to also a for the return movement which becomes operable once the marking been effected and which serves automatic return of the target disc into a zero position at the edge the target In the annexed drawing there is shown one illustrative form and which serves for defining described in the following detaildd 1 and 2 represent and the aiming parts of the new respectivel both figures being is a wiring the new arrangement Turning to on a supporting structure 1 there m an ordinarily white target sheet At the right hand to corner of the sheet is positioned the target disc affixed to a carrying bar The position shown may he considered as zero To the is fixed apart from the target sheet 2 a mechanism indicated as while by the 5 and serving to the target 3 carried on the carrying la The assembly indicated as a b the numeral 5 comprises t guide rails 6 and 7 which extend normal to one another and to each of which coordinated and positioned in a screw spindle 9 To each of the spindles ooupled revoraable electromotor 10 and 11 which motor can made to being controlled by the aiming in or the other Onto spindles screwed a 13 The nut 12 is fixed to end of the bar which has been the disc carrying bar some distance from nut 12 provided a 6a through which the second rail 6 the bar with disc 3 thereon can be moved up down The rail 6 being connected with the motor as troll as the target disc on the The whole mentioned is movable on the said rail 7 by means of three sleeves 7a which slide on rail 7 and are affixed to a plate the motor 10 rests as can be seen in the As can be seen 1 shaft of 10 is normal to spindle 8 add the is transmitted to the spindle by of a bevel gear The middle one o the sleeves 7a is fixedly connected by connecting piece 7c to the nut thus ensuring the movement of the assembly carried 6 together with this rail itself on the rail During target practice the aiming person o the looks through the customary visors which are provided on the rifle 17 The rifle is fixedly held in a holding arrangement 18 of customary design built in such a way that after release of clamps the can be swung upwardly as well as this way the rifle can be aimed by the instructor at a chosen point on the sheet 2 and can be fixed in In lieu of the ri show in drawing it of course possible to use any other sighting By means of a as fo instance a four way switch 1 motors 10 11 may be switched o in one or the other Thereby it becomes possible to locate the target disc 3 onto whatever chosen point of target sheet If now the target disc is in a position which gives the pupil or recruit reasonable certainty that a round from the rifle 17 would hit the center of the disc that to say that this disc is in coincidence with the line of the can mark this point on the target To this end he operates a preferably by pressing the trigger of rifl which operate a device 20 provided on the targe disc 3 that the said marking device indicates or marks a point on the sheet 2 through the opening 21 in the center ef the This could be brought about by pencil in the direction of the sheet or it could be done by a needle with aid of an Once the marking operation has been the disc 3 automatically into the position shown in the The numeral 22 indicates two signal one of which may a red These lamps could be wired in such a way that the red is during aiming and the the white is lighted after conclusion of the Such an arrangement facilitates the task of a supervisin person and gives better picture of stages and conditions of the As ca seen from the wirin diagram of 3 the automatic return movement of the target device could brought about in such that the return of the trigger Z or whatever other button used for operating marking the motors 10 and 11 switched Cuttin current to the motors is brought about by the two contacts Al and A2 which open when the target disc arrives at the uppermost position at the right hand of the If a recruit or pupil directs the target disc by means of a four way switch to a desired point by feeding current to the fields F of motor 10 and 11 in one or the other the contacts Al and close as soon as the target disc leaves the zero As soon the point reached which has bee chose by the latter presses the which thereby energized trigger Z u a relaysB C O and solenoid of markin arrangement 20 ii The relays C close their and solenoid marking into the central opening o the target During this operation the disc remains stationary since the relay E or D respectively which follow contacts and are yet not under The contacts are self retaining contacts which warrant excitement of relays B and C even when the trigger Z has returned to its initial Hereby solenoid becomes less the markin pencil to its position of rest by means of a At same time a current over relays E D since now the contact and are By exciting these relays contacts and whereby the motors 11 are fed directly with current the is moved by these motors zero Sinc the relays E and when excited also their contacts and it cannot happen that by unintended opening of workin of switch 19 during the return travel a wrong operatio brought When final positions are reached the two contacts are opened independently another whereby the respective B and C become the self holding contacts and As workin current it advisable to use low current which nay supplied from accumulators or through a There a possibility to put the above invention into practice in various It would be possible to effect the movement of target disc by means of pull ropes or by means of a small transportable wireless the possibilities feature common that they do not require any personnel for working the and one Instructor is sufficient to supervise several Instead of a target sheet is possib le to use a of from which respective sheet is by person It obvious by the comld caused to whatever person a practicin one or a supervising and that it makes it to give intensive instructions using only one insufficientOCRQuality
