The present invention relates to gun targets and more particularly to a motorized target structure `which 1s readily controllable and effective for use wlth either rifles and/or Shotguns.
The types of targets in use heretofore generally require considerable time and effort on the part of the party practice shooting in walking to and from the target after firing to inspect the results and to replace the target. Oftentimes, as in the military service, for example, an individual was stationed in the area behind the ltarget to accurately record the results of each round of target practice, which activity was not without diiculty in view of the generally large number of partlcipants practlcmg.
By virtue of the applicants novel invention, a motorized target structure is provided which may be operated to position the target at any desired firing distance or range, which permits the ready rotation of the target from a remote point, and which affords accurate identiiication of the target and hence the results of the practice round. The applicants novel target structure is adaptable for use for either rie and/ or shotgun practice and may be effectively installed for either on indoor or outdoor target range.
A principal object of the present invention, therefore, is to provide a motorized target structure which is operable at a point remote from the target.
Another object of the present invention is to provideV a motorized target structure which is readily positionable to any preselected target distance and which is simply and effectively rotated, as desired', to reveal new targets.
Another object of the present invention is to provide a motorized target structure having7 targets forming a part thereof which are adaptable for use with either rifle and/ or shotgun practice, with the individual targets being readily positioned and removed.
A further and more general object of the invention is to provide a motorized target structure which promotes safety as well as accuracy on the target ran-ge.
Other objects and a better understanding of the invention will become more apparent from `the following description, taken in conjunction with the accompanying drawings, in which:

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustra-ted device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring now to FIGS. l, 2, 3, 4 and 5, the applicants novel motorized target Istructure having a target dial designed for shotgun practicing comprises a frame assembly 17 including an upstanding H-section 17a, a box-like base portion 17b and angled brace members 17C. In the typical embodiment described herein, the frame assembly 17 is made from angle and channel iron. One end of the box-like base portion 17b has double-flanged wheels 28 conventionally mounted thereon, while the other end thereof is supported by Wheels 41'mounting through equalizer assemblies 40. v
An equalizer bar 40a of each equalizer assembly 40 is supported at points 44 by an -arm 17d extending downwardly from the box-like base portion 17b of the frame assembly 17 and by a U-member 39 which extends over and around an element forming the box-like base portion 17h of the frame assembly 17. A spring 45 extends between the element forming the box-like base portion 17b and the inner top wall of the U-member 39 of the equalizer assembly 40 (see FIG. 4). As will be -apparent from the following, the equalizer assembly 40 is provided to compensate for any unevenness in rails 43 of the track on which the applicants novel motorized target structure moves.
Disposed hon'zontally from the opstanding H-section 17a of the frame assembly 17 is a header bar assembly 15 having angled brace members 16 at either end thereof which serve to support a shield 1 extending in front of a target dial 2 of the target structure. The lower end of the shield I is conventionally secured to the front of the box-like base portion 17h of the frame assembly 17.
Extending upwardly from the header bar assembly is a collar 15a which supports one end of an inner spindle 7, the other end of which is rotatably supported through a fiange 7a to the shield 1. An outer spindle 6 fits over the inner spindle 7 and connects the target dial 2 through flange 6a, a collar 13 having a set-screw 13a thereon being provided to maintain clearance between the target dial 2 and the shield 1. A sprocket wheel 11 on a hub 8 is freely rotatable on the outer spindle 6 adjacent the collar 15a, with a spacer collar 14 having a set-screw 14a thereon being provided therebetween. As should be apparent, the set-screws 13a and 14a on spacer collars 13 and 14, respectively, serve to adjust the end clearance of the outer spindle 6 on the inner spindle 7.
The sprocket wheel 11 is rotated through a chain 12 driven from a conventional sprocket-type take-off 2f) on a typical ratio motor 21, the latter being mounted on the H-section 17a of the frame assembly 17. The sprockettype take-ofic 20 has a striker 18 attached to the rotating shaft thereof which intermittently engages a normally closed kick-out switch 19, to be discussed herebelow.
A disengaging device 10 extends from an irregularly shaped fiange9 which surrounds and is secured to the outer spindle 6, as by welding at 9a, for example. When the disengaging device 10 engages the sprocket wheel 11 through member 10A thereof, movement of the sprocket wheel 11 effects rotation of the target dial 2. When the disengaging device 10 disengages the sprocket wheel 11 by being moved outwardly and rotated slightly, for example, the target dial 2 may be rotated independently of the operation of the ratio motor 21. The latter feature is particularly useful when placing new targets on the target dial 2.
The applicants novel motorized target structure is movable along the rails 43 of the track through the operation of another ratio motor 22 mounted on the base portion 17b of the frame assembly 17 which drives a sprocket 25 through a sprocket 24 and a sprocket chain 23 arrangement. Rotation of the sprocket 25 effects rotation of a shaft 26 and hence the double-hanged wheels 28 secured at each end thereof. Thus, the entire target structure is movable at will of the operator.
The target dial 2, preferably made from metal, is generally circular in shape and has a plurality of target positioning devices positioned adjacent the periphery thereof, each comprising a clamp member 4 cooperating with a block member 3 through bolts 4-A at two sides thereof having a spring 4-B therearound between the back of the target dial 2 and a bolt 4-C. In use, the clamp member 4 is lifted upwardly or away from the block member 3 so that the target -B may be placed thereunder and retained in position by the spring-urged action thereof.
The target dial 2 also includes on the face thereof a series of numbers 5-A which are provided as a means of identification for the respective targets. The numbers S-A may be secured to the face of the target dial 2 in any desired manner, such as through screws S--C and spacers S-D, for example. As should be apparent from FIG. 1, when the target structure is assembled, only one target and the respective number S-A therefor is visible through an opening provided in the shield 1.
Referring now to FIGS. 6, 13, 14, 15, 16 and 17, a modified target dial A-3 is disclosed for use for rifle and/ or shotgun practicing. The modified structure, which is an open back type target permitting passage of bullets therethrough, is used in conjunction with the motorized target structure discussed above, actually, however, being substituted for the target dial 2 and the outer spindle 6 therefor. FIG. 13 discloses the substituted structure extending from a spindle 6', the modified target dial having supporting braces A-2-C between the spindle 6' and radially disposed spokes A-Z-B, the latter being secured to a disc A-2-A affixed to a central hub of the target dial.
Disposed between the spokes A-2-B are target panels A-3, preferably formed of wood, for example, and positioned by screw means extending through the spokes 4 A-Z-B. Lugs A-2-D provided on the spokes A2-B extend beyond the plane of the side edges of the spokes A-Z-B and serve to retain a target A-S-B in position for practice shooting. Each of the targets A-S-B have a characteristic shape in plan View (see FIG. 15) which assists in the positioning thereof, with the top edge of each target being secured to the target panels A3 by a Spring clip A-4 (see FIGS. 6 and l5). An identification number A-S-A is positioned between the target A-E-B and the disc A-2-A so that any particular target A-S-B may be readily located after the conclusion of the round of firing. It should be apparent from FIG. 15 that only one target A-S-B and the corresponding identification number A-S-A therefor is visible in an opening provided in the shield A-1 of the novel target structure disclosed herein.
FIGS. 7, 8, 9, 10, 11 and 12 are each pertinent to the electrical circuitry and the mechanical features associated therewith for the control of the movement of the motorized target structure as well as the rotation of the target dial. Referring first to FIGS. 1, 2, 7, 8 and l2, a bracket 34 is shown disposed on the box-like base portion 17b of the frame assembly 17, the bracket 34 having an insulating block 3S-A secured thereto. Electrical contacts 36, 37 and 38, preferably of the sliding copper reed type, are secured to the insulating block 35-A and serve as part of the electrical circuit for controlling the rotation of the target dial. Electrical contacts 36, 37 and 38 are provided for contact with a neutral line 49, a hot line 50 and a hot line 51 for feed back to a relay 55, respectively, to be discussed herebelow.
Referring particularly to FIG. 8, a portion of the track structure at a remote target position is disclosed including track i3-A on standard 43-B having a base A13-D between which ties 43-C extend. Extending upwardly from the ties 43-C are brackets 47 which position a body member 48 on which the neutral line 49, the hot line 50 and the hot line 51 are located, the latter being in the form of elongated contact rails. It should be noted that the bracket 34 is vertically adjustable on the frame assembly 17 to permit good electrical contact between the electrical contacts 36, 37 and 38 and the lines 49, S0 and 51, respectively.
Referring now to FIGS. 2, 3, 8, 9, 10 and 1l, the applicants novel motorized target structure includes electromechanical components for controlling the movement of the target assembly along the rails 43A of the track. Extending downwardly from the box-like base portion 1712 of the frame assembly 17 is a bracket 29, adjustable vertically, on which is positioned a reversing switch 30 for controlling operation of the ratio motor 22. The reversing switch 30 coacts with a breaker-striker 46, the base portion of which is secured by screw means to one of the ties 43-C extending between the rails 43-A.
Referring particularly to FIGS. 9, 10 and 11, the breaker-striker 46, which acts dually to break a circuit and to reverse the reversing switch 30, comprises a main body 46-A having portions thereof oppositely pivotable at lower pivot 46-X and at upper pivot 46Y, with a spring 46-G being provided with the upper pivot t6-Y. Extending upwardly and outwardly from the base portion of the breaker-striker 46 is an arm 46-1, having a spring 46-H at the upper end thereof connecting to the main body 46-A and urging the entire assembly into a vertical position at lower pivot 46-X. When in a vertical position, electrical contact is made between switch points 46-B and 46C, switch point 46-B extending upwardly from an insulator 46-D into which it is attached through suitable screw means. Contact with the other electrical circuitry (FIG. 7) is made through connector contacts 46-E and 46-F, with insulator 46-D being behind the latter.
In the typical embodiment described herein, two breaker-strikers 46 are used, each being positioned on the track ties 43-C at locations representing the desired distance of travel of the motorized target structure from the operator, i.e. the position of the breaker-strikers 46 define the points between which the target structure moves. Noting particularly the sequence of operation of one of the breaker-strikers 46, as represented in FIGS. 9, l and 11, the direction of the arrow indicates the movement of the target structure which, as discussed hereabove, has the reversing switch 30 secured to bracket 29 extending therefrom.
FIG. 9 shows the breaker-striker 46 in a normal position, i.e. with electrical contact being made between contacts 46-B and 46-C thereon. As the reversing switch 39 contacts the breaker-striker 46, the body portion Ltti-A thereof pivots at point 46-X, breaking electrical contact between contacts 46-B and 46-C, and causing the ratio motor 22 controlling target movement to stop operating, to be discussed below with reference to FIG. 7. The target structure continues to move by reason of momentum for a short distance after the ratio motor 22 stops operating, increasing the tension of the spring 46-H between the bracket 46-J and the main body portion 46-A, which ultimately causes the toggling or reversing of the reversing switch 30 (see FIG. 10). The breaker-striker 46 then returns to its normal vertical position, but the re-closing of the electrical contacts 46-B and 46-C thereby does not affect operation of the ratio motor 22, for reasons to be discussed herebelow.
FIG. 11 discloses the manner in which the reversing switch 30 may pass over the breaker-striker 46 by permitting the upper part of the main body portion 46*A to pivot at the upper pivot 46-Y, without disturbing the closed condition between contacts 46-B and 46-C. When the ratio motor 22 again operates, the target structure moves down the rails to the position of the other breaker-striker 46, which is in reversed physical position,y
where action similar to the preceding takes place and the target structure stops.
Referring now to FIG. 7, various of the components discussed above are schematically shown in respect to the over-all electrical circuit for controlling movement of the target structure and for controlling the rotation of the target dial. The circuit includes a relay 55 having a pushbutton 56 associated therewith for target dial rotation control; a relay 58 having a pushbutton 57 associated therewith for target structure movement control; a conductor 52 for feeding current back to the relay 55; a conductor 53 which feeds current to the ratio motor 21 when the relay 55 is energized; a neutral conductor 54 for the ratio motor 21; a neutral conductor 59 for the ratio motor 22; a conductor 60` which feeds current when the relay 58 is energized; and, a conductor 61 which feeds current back to the relay SS after the relay 58 is energized by moving the pushbutton 57 and releasing, the latter conductor continuing to feed current until the circuit is broken by the target structure striking the breaker-striker 46 through the reversing switch 30. It should be understood that 62 represents a neutral line while 63 represents a current carrying line.
When the target movement control pushbutton 57 is closed and released, the relay 58 is energized and the ratio motor 22 for driving the target operates through conductors 59 and 60, which current is supplied to the ratio motor 22 through sliding contacts 31 and 32 and the reversing switch 30. It should be noted that the contacts 31 and 32 are positioned on a bracket 33 extending from a side of the base portion 17b of the frame assembly 17 (see FIG. l). As the target structure moves from one end of the track to the other, current is also fed back to theV relay 58 through the conductor 61 which includes the breaker-strikers 46 therein. Relay 58 remains energized.
When the target structure moves past one of the breaker-strikers 46, the reversing switch 30 thereon contacts the breaker-striker 46, las discussed hereabove, breaking the contacts 46-B and 46-C and thereby the feed-back circuit through conductor 61 to the relay 58.
Relay 58 is then de-energized. Inasmuch as the reversing switch 30 is reversed, when the circuit is re-energized again through use of the pushbutton 57, the target structure assembly will then move along the track in an opposite direction. Y
It should be understood that the electrical contacts 49, 50 and 51 for the dial target rotation control circuit are positioned at a location between the rails 43-A of the track so that when the target structure stops moving in one direction, as discussed above, the sliding contacts 36, 37 and 38 on the structure will be in electrical contact therewith. When pushbutton 56 is then used, current can flow to the ratio motor 21 for rotating the target dial. The relay 55 is energized and current is fed back thereto through the conductor 52 and through the normally closed kick-out switch 19, thereby maintaining the relay 55 in energized condition.
As the ratio motor 21 for the target dial rotation operates, the shaft of the sprocket-type take-oil 20' rotates and the striker 18 which is secured thereto also rotates. The mechanism is assembled so that each time the shaft makes one rotation, the striker 18 strikes the kick-out switch 19 mounted on the frame assembly 17, breaking the target dial control circuit through the ratio motor 21 and de-energizing the relay 55, thereby causing the target dial to stop in the opening provided in the shield each time the pushbutton 56 is used. After all the targets are used, the target structure may be returned, as described above, to a position close to the operator, and new targets placed on the target dial.
Thus, it should be apparent from the preceding that the applicant has provided a novel motorized target structure which is readily adaptable for use for either shotgun and/ or rifle practicing with different target dials, which is operable remote from the target structure to move the target to the desired range and to rotate the target dial from one target to another, and which promotes safety as well as accuracy on the tiring range.
The motorized target structure disclosed herein is susceptible to various changes within the spirit of the invention. For example, the current feeding arrangement may be modified to include provision for a different type of electrical pick-up. Thus, the above description should be considered as illustrative and not as limiting the scope of the following claims.
