l The invention described herein may be manufactured and used by or for the Government for governmental purposes, without payment to me of any royalty thereon.
This invention relates to improvements in targets designed to furnish aerial gunners with ground target practice in shooting at rapidly moving objects, and has for an object the provisic-n of a ground target system for simulating the rapid movement of a target on a gunnery range, such as an airplane, by the employment of a series of individually movable target members mounted on xed supports at substantially equally spaced points between two spaced locations on the range and progressively moving each target, one after the other, from one of the locations to .the other location.
Another object is the provision of a single operating means common to a plurality of target devices, each movably mounted at iixed progressive points on a gunnery range on a line extending between spaced locations and cooperating means between the target devices and the operating means for moving the target members one at a time in a progressive order.
A further object is the provision of a single operating cable means for progressively moving the target members mounted at xed points along a line extending between two locations on a gunnery range in which a minimum amount of linear movement of the cable means progressively actuates all of the target members.
A stil] further object is the provision of a target device for simulating a target rapidly moving between spaced locations on a gunnery range by utilizing a series of individually movable target devices disposed at uniformly spaced fixed points, relatively close together, between the two spaced locations and a relatively slow moving linear actuator means having a plurality of spaced abutments thereon, one for each target and engageable with its target to move the same, said abutments being spaced a slightly greater distance apart than the spacing of the targets, whereby a relatively short linear movement of the actuator progressively actuates all of the target members.
A still further object is the provision of a movable target device disposed on a stationary support for use on a gunnery range in which a target member is normally disposed in an inoperative position, out of the line of fire, when the device is in use on a range, and a remote controlled actuating means for the moving of the target member tov an operative iiring position and immediate relea-se of the target member to permit the target member to return to its normal inoperative position.
Other objects and advantages will appear in the following description taken in connection with the accompanying drawings in which like reference characters refer to like parts.
Fig. 1 is a somewhat diagrammatic plan view of a gunnery range disclosing my improved target apparatus as installed thereon.
Fig. 2 is an enlarged perspective view of one of my improved target devices and a portion of the target actuating means or cable, the target member being disclosed in normal inoperative position.
Fig. 3 is a view similar to that disclosed in Fig. 2, illustrating the target member in operative position.
Fig. 4 is a diagrammatic illustration of a modied form of actuating means for the target members.
Referring to Fig. 1 of the drawings, the numeral i indicates a gun position located on a gunnery range and 2 the rampart for the gun. Extending across the range between spaced locations 3 and il and 5 andii are a plurality of substantially equally spaced target devices indicated generally at l and l' respectively, each comprising a iixed or stationary support 8 on which is movably mounted a target member 9.
The target members 9 are preferably formed of some suitable flat or sheet-like material and are normally positioned on their supports in inoperative or horizontal positions, as seen in Figs. l and 2 of the drawings.
A single operating means for actuating the target devices 'i between the locations 3 and 4 to move them to their operative position as shown in Fig. 3 is provided in the form of a cable member i0 extending between the spaced locations 3 and and are trained over pulleys l2 at the locations 3 and 4, and thence over pulleys i3 and around a winch I4 actuated in any suitable manner, either manually by a crank or by a speed controlled motor device I5.
The target devices 1 operatively associated with the actuating cable Il), extend in an imaginary line across the line of nre of the gun I between the two locations 3 and d and are spaced comparatively close together. Assuming that the distance between the locations 3 and 4 is about 450 yards, the target devices would be placed approximately 50 yards apart. To simulate a target movf ing at -miles an hour, the targets between 3 and d should all rise into operative position and fall in approximately eight seconds, since the distance between the rst and last target would be about 400 yards. The mechanism for moving the targets from their inoperative positions to their operative positions is such that about one and a half seconds is required to bring each target to its vertical position, one target being always in view while the other adjacent targets are either being moved in their operative or to their inoperative positions.
The line of target devices 'l' extending between the pulley l2' at the location 6 and the winch Iii at the location 5 extends substantially directly away from the gun l, and the distance between the last and first target is approximately 409 yards with a spacing between the target devices of about 50 yards.
The target devices between the locations 5 and 6 are operated in a progressive order, one after the other, from one of said locations to the other location by a single linear actuator or cable t9 extending around the pulley I2 at the location 'i6 with the other end portion of the actuator i9 wrapped around the winch i4', power driven by a speed controlled motor i5', or manually operable by a crank. These last-mentioned target devices are operated in a manner similar to the before-mentioned target devices located between the locations 3 and '4.
VThe cables l0 and t0 'have a plurality of abutment members 44 fixed thereon for successively engaging Vthe target devices, one after the other,
to raise 'the target 'members in-a progressive order and lallow them to return to their former inoper- -ative positions by gravity. 'The target members in either mentioned series when actuated by the cable it) or the cable I9' simulate a target moving rapidly toward or away from the gun l de pending upon the positioning of the abutment members viixed on `the cable i0 or the cable I0 for progressively actuating the target members and .later to be described.
'It -is preferable 'that the `iixed supports 8 for the target members be either placed in a trench,
-a-n opening, or behind an embankment, so that thesupports and the `target members be out of the line of lire Ia's well Yas out of the possible sighting line of 'the Sgun when the target members 'are in their inoperative position in order that no parts of the devices be visible to the gunners except when thetarget members are moved to their operative positions.
'Referring now to Figures i2 and 3, the fixed supports 8 have their 'upper ends apcrtured at I8 to pivotally receive the *end .portions of a cross shaft I9 having a target arm 29 fixed thereto, carrying the target -iinemberli. The target member '9 is secured to the arm '22 by any suitable fastening means :2i and vis formed of flat or sheet material cut into any desired configuration, such las'the -outline of an airplane, tank, truck or other object.
The cross shaft i9 has a weighted arm 22 xed thereon at right angles to the "target arm 29 and depending downwardly as `seen in Figure 2 when the target is in vits Vinoperative position. Adjustable Avweights A23 'are applied to the arm 22, which Ymay be varied to change the speed of return of the target -member to its normal Vinoperative position.
The cross shaft I9 `and weighted arm 22 carry a 'segmental plate 24 to which one end of a target actuating cable 25 .is attached, the end of the cable being secured to alprojection 26, adjustably secured ina slot 21 `for-med in the plate 2li. Adjustment roi the projection ' 26 in the v`slot 21 changes the effective direction `of pull of the cable 25 on the weighted arm 22 and effects the amount of swinging movement which can be communicated to the target arm 29 by the cable 25.
A xed stop member on rest 29 is positioned below the target member 9 on suitable standards Sil. The stop member 29 may be provided with cushion members 3l for resiliently arresting the return movement of the target member 9 to inoperative position a-nd the intermediate portion of the rest may be recessed at 32, to receive the -target arm 26 and the cable 25 when the target is in inoperative position.
A check member or stopI cable 33 is connected between the target rest structure 29 and the 'target member 9 on target arm 29 to limit the swinging movement of the target when the same is moved to vertical position.
The individual target devices each include a Vxed platform or support 34 carried on standards 35 and of somewhat T-shaped outline.
`.A target actuating lever 35 is pivoted at one end, as indicated at '31, vto the platform Sli and has a limited arc of movement between pins 38- 39 projecting upwardly from `the platform. 3G. The lever 35 is somewhat channel shaped in cross section, having a Yseries of apertures H5* formed in the opposite edges of the channel to receive an adjustable pin '41.
The targetactuating cable 25 is attached to the pin 1li and swinging movement of vthe lever 36 toward the stopy pin 3:9 actuates the cable 25 to raise the target member 9 to its vertical or `operative position.
The free end of the lever 36 is formed with inwardly tapered opening or V-shaped slot 42 through which the linear actuating member or cable i9 extends, and a retaining pin 43 is positioned in the vedge a'n'ges of the lever 36 across the mount of the slot 42 to Ymaintain the cable i9 therein.
The cables Hi and 'i' are each provided with a plurality oi abutment members All, preferably spherical in shape, and adjustably iixed on the cable, one abutment member being provided for each target device l, and pulleys i5 on the platform 35 support the cables I9 or I9 in operative `position with respect to the lever 3S.
As previously set forth, the target devices are positioned along lines between the spaced locations with a substantially equal spacing arrangement between 'the target devices. The abutment members M on the cables 19 and I0' are also uniformly spaced, but the spacing between the Aabutment 'members'is diierent Vfrom the spacing between target devices Yand preferably greater.
It shouldY beV observed that when the target 9 is in inoperative position with the wall of lever -z'i against the stop pin 38, the walls of the slot `or tapered opening incline rearwardly or in the direction of movement of the cable i0 and the abutments M upon contact with these walls are cammed toward the pivot of the lever and the narrower portion of the slot.
After the lever has been shifted to move the target member to its vertical or operative position vand the lever 3B Vis moved against the stop 39 the walls of the `lever surrounding the opening or notch 42 incline inthe opposite direction producing an outward camming action on the abutment M moving the same toward the wider por- -tion of the tapered opening until it reaches a width sufficient to pass the abutment. The abutment thenescapes through the wider portion of the opening' freeing' the lever `36 and the Weight 23 immediately returns the target 9 to inoperative' position, as seen in Figure 2.
The' abutment members 44' are so placed on the actuating cables l and l0 that they will progressively engage levers of the target devices. In other words, the abutment member for the first target device to be operated is placed closest to the lever 36 for the target device, the next target device to be actuated has its abutment on the cable I0 placed a little farther away from its actuating lever 3B, and so forth. The cables Ill or. l0'. are only moved a relatively short distance in order to progressively actuate all of the target devices and the target devices are moved to their operative positions and released to return to their inoperative positions in a very rapid succession, depending upon the speed of linear movement of the cable I0. The actual speed of linear movement is relatively slow, compared to the simulated rate of movement of the target.
The above device provides a target which is extremely simple in construction and operation, with a minimum number of relatively slow moving parts, simulating a target moving at an extremely high rate of speed. After the target vdevices have all been actuated, the winch I4 or the winch I4' may be reversed, moving the abutment members into their original starting positions. VThe inclined faces of the levers 35 cam the abutments into the larger parts of the openings 42 in the levers so that they can readily pass therethrough in the return movement.
Referring to Figure 4, illustrating a modified form of operating mechanism for progressively moving the target members to their operative position and return, the target members 45 pivoted at 41 are each provided with an actuating arm 48 to which is connected an actuating link 49. The link 49 is connected at its opposite end to a crank pin 5U on a worm driven disk 5I having a larger disk 52 fixed thereto and formed with a notch 53 in its periphery. The disk 5l is driven by a worm on the shaft of the driving motor 54 and current is supplied to one terminal of all of the motors 54 through the common feed wire 55, while the other terminals of the motors are connected by circuit wire 55, 55', 55" to contact members progressively arranged around on insulated control member 51, the latter having a rotary contact blade 58 thereon connected to the current source by the conductor 59.
Each target device is provided with a shunt circuit controlling resilient contact blade 55 connected to one side of the current source by the conductor 6 l.
The free ends of the contact blades @il are formed to flt the notches 53 when the target members are in inoperative position, but upon initial operation of the motors 54 the contact blades are forced laterally out of the notches 53, into contact with the normally spaced contacts 62, having conductors 63 leading therefrom to the motor terminals which are connected to the conductors 56, 55', 56.
As the contact blade 58 is rotated around the ring of contact terminals on control member 5l, the motors 54 are progressively energized, one after the other to displace their contact blades 60. The displacement of the blades 65 maintains an operative or closed circuit to the motors 54 untilworm wheel 5| makes a complete revolution, moving the target to its operative position, and back to its inoperative position again. The end of each blade 60 then drops into the notch 53 breaking the circuit to the motor. The ends 6 ofthe blades act as detents for arresting rotation of the disk 5l with the target member 46 in its inoperative position- The control member 58 may be operated manually, or by power, and as the same rotates, the motors 54 of the target devices 45 are progressively energized, bringing the targets into and out of operative position one after the other in the same manner as in the preferred form of the invention, simulating a rapidly moving target.
Various types of guns may be employed such as a single machine gun, and even relative movement of the gunner can be realized by mounting the gun on a vehicle such as a jeep car and speeding it along a roadway (not shown) which may be prepared on the range.
In the sighting of guns from a rapidly moving airplane or other moving vehicle, the forward movement of the gunners plane or vehicle must also be accounted for and while devices to compensate for these corrections are known and somewhat automatic, it is proposed to provide a simple mechanism attached to the mount of the gun that will shift the rear gun sight as the gun is swung at an angle to follow the indicated line of flight of the target which will necessitate a realistic adjustment of the gun and sights by the gunner.
It is believed that this target apparatus is superior to other gunnery targets in that it is possible to provide aerial gunnery practice in firing at ranges with speed of movement of the target equal to those encountered in actual combat, without the employment of the rapidly moving targets, or other complicated control devices.
