FLYING TARGET FOR TRAP SHOOTING Filed Oct. 8, 1962 2 Sheets-Sheet 2 United States. Patent 3,169,767 FLYING TARGET 1 R TRAP-SHOOTING Samuel H. Bingham, Jr., Winnetka, IlL, assignor to Black Products Co., Chicago, IIL, amorpnmfiouof Illinois Filed Oct. 8, 1962, Ser. No. 229,119 ll-Claims. (ill. 275-1054) This invention relates to improvements in flying targets, sometimes known as clay pigeons or clay targets, suitable for use in trap shooting or the like.

The general object of my invention is to provide a target which is constructed in such a manner that, whenhit by a single shot or pellet, the likelihood of breaking will be considerably increased as compared with comparable targets of the prior art. More specifically, the construction is such that if a fragment is ,broken off, it will be sufiiciently large so as to be clearly visible, to the end that the shot will be scored as a hit.

Such targets are made of a suitable mixture of pitch and clay, or pitch and limestone dust, which provides a relatively fragile structure. However, the stress incident to the operation of the trap requires a relatively strong structure particularly in the radial direction. Therefore, it has been the practice to make the target in the form of a hollow dome-shaped structure, partially because this shape is inherently strong, and partially because it presents a larger projection to the path of the pellet, thereby increasing the chance of a hit.

However, it has been found that unless the pellet hits the curved surface of the dome within a certain small area which is close to the diametral line (termed a diametral hit) and which is also sufficiently low on the dome as to present a high angle of impact to the pellet path, the pellet will tend to glance off. More specifically, if the point of impact is offset from the diametral line (termed an ofiset hit) the pellet will glance off due to the low angle of impact. Also, a diametral hit on the upper part of the dome surface will glance oif.

Even where the pellet penetrates the target in the relatively small high impact angle area, the piece of target knocked out may be so small as to be not perceptible, with the result that the hit will not be scored.

The present invention provides a target having a smooth rim portion and a dome portion characterized in that the dome portionis provided with a number of closely spaced depressions, the wall of each providing one surface portion or facet of high impact value with respect to a diametral hit, and other surface portions or facets of high impact value with respect to oifsethits.

I have found that if the surface irregularity of the dome does not extend to the outer rim surface, that the trajectory of the target is not adversely affected, as by skewing. Tests have indicated that the dome depressions actually stabilize the target trajectory.

I have also found that if the depressions are aligned with each other, that the pellet will not only penetrate the target, but will knock out a fairly large piece, with the result that the hit is visible from a distance and will be scored. In many instances, the hit will cause complete disintegration of the dome. This is due to the fact that the alignment of the depressions provides certain lines of potential fracture.

. Other objects, features and advantages will become ap- I FIG. 4 is a sectional view taken along the lines 4-4 of FIGS. 1 and 3;

FIGS. 5 and 6 are views corresponding to FIGS. 3 and 4 but showing a modified shape of depression;

FIG. 7 is a view similar to FIG. 6 but showing an alternative of the FIG. 6 construction;

FIG. 8'is a view similar to FIG. 3, but showing another modification;

FIG. 9 is an enlarged fragmentary section similar to FIG. 2, but showing a further modification;

FIG. 10 is a fragmentary plan view of the dome showing another type of depression; and

FIG. 11 is an enlarged fragmentary section taken along line ll11 of FIG. 10.

With reference now to FIGS. 1 and 2, the target comprises a rim 10 and a central disk-like portion 11 which are connected to each other by a curved wall comprising the dome 12. The upper surface of the disk portion 11 is preferably recessed somewhat below the high point of the dome 12.

The rim It includes a flange portion 13 of substantial thickness and a shoulder 14 adjacent thereto. The shoulder 14 cooperates with the trap in such a manner that the flange portion 13 of the rim can be received in the groove of the trap in the customary manner.

The dome 12 is provided with a number of depressions 15, each of which, as shown in FIG. 3, comprises an inner wall Itntwo radial Walls 17 and a flat bottom wall 18 which intersects the surface 19 of the domelZ, thus providing a step type of depression. The inner wall 16 is substantially parallel to the, spinning axis 20 of the target, and the bottom wall 18 is substantially perpendicular thereto.

In FIG. 1, the arrow 21 indicates the pellet path of a diametral hit, and the arrow 22 indicates the pellet path of an offset hit. The broken line 23 is the diametral line above referred to, that is, that diameter of the target which is parallel to the

pellet paths

21 and 22, when viewed in projection, as in FIG. 1. Itwill be understood that the target, when in flight, is spinning and therefore there is relative movement between any given depression 15 and the diametral line 23. Furthermore, the target when in flight is inclined to the horizontal and also inciined to the

pellet path

21 or 22, somewhat asshown in FIG. 2. 7

It will be seen therefore that the inner wall I6 constitutes a surface portion or facet of high impact value with respect to the pellet path 21 of a diametral hit. Gne of the radial walls 17 presents a surface portion or facet of high impact value with respect to the pellet path 22 of an offset hit.

e As shown, in FIGS. 2 and 4, the depressions 15 provide thin wall portions 24 which are aligned with each other to provide a line of potential fracture which extends in a circumferential direction. FIG. 1 indicates the concentric orientation ofthese lines 25 of potential fracture.

Since the depressions 15 are separated by dome surface portions 19 which present surfaces of low impact value, the effectiveness of the target may be increased either by undercutting the depression as shown in FIG. 9, or by enlarging the depressions as shown in FIGS. 5 and 6 which reduces or eliminates the surface areas 19. In the modification of FIGS. 5 and 6, the radial walls 17' are sloped to provide a ridge 26:. of tapering cross section which serves as an abutment which is effective in taking up the force of the impact and transmitting it to the body of the domev 1210 causefracture along one or more-of the lines 25 of potential fracture.

In the alternative construction of FIG. 7, the upper portion of the ridge 26' is rounded. e

In the modification of FIG. 8, the depressions 27 are of semicircular shape instead of rectangular, thus providing a continuous wall which has one portion 23 which is of ably weakens the same.

face 19' will tend to cave it in, the undercut dome offering comparatively little resistance to the pellet with the result that the pellet will engage the remote wall 34. Thus, substantially thefull, force ofthe impact is taken up by the remote wall 34, tending to cause fracture at the thin wall portion 24", and along lines 25 of potential fracture.

A modified form of undercut depression is shown in FIGS; 10 and il in which the depressions 35 are of circuiar cross section and of smaller diameter than the

depressions

15, 27, or 31. The spacing between'the depressions 35 is less than the diameter. The thin wall portions 36 are aligned so as to provide lines 37 of potential fracture which intersect each other. Here, as in FIG. 9, thedepr'es'sions 35 have an outer wall 38, as Well as an inner Wall 39, and the outer wall 38 provides a sharp edge 40. As a result, a pellet striking the undercut dome surface '19" at a point between adjacent depressions 35 will tend to cave it in and strike the remote or inner wall 39 to cause fracture along one or more of the lines 37.

In the embodiments shown, the target preferably has an overall diameter of approximately 4% inches and an overall height of approximately 1% inches. The thickness of the disk portion 11 is approximately /2 of an inch, and the thickness of the other portions follows substantially the proportions shown in FIG. 2. j

In FIGS. 1 'to'4, the depressions are arranged in three tiers and the width dimension of the depression is of the order of from A to 4 of an inch. In FIGS. and ll, the undercut depressions 35 are substantially /8 of an inch in diameter.

In each instance, the depth of the depression is in excess of one-half of the wall thickness at. that point. Preferably the, thin wall portions 24 range in thickness from .025 inch up to A of an inch, and the same applies to the thin wall portions 36 of FIGS. 10 and 11.

In the embodiment of FIGS. 10 and 11, the spacing varies due to the circular orientation, but ingeneral the distance between adjacent depressions 35 is less than their diameter. As an overall parameter, about /3 of the vertically projected area of the dome 12 is occupied by the depressions 35. In the embodiment of FIGS. 5 and 6, at the other extreme, substantially all of the vertically'p-rojected area of the dome is occupied by the depressions In each of the embodiments shown herein, the depression presents a surface portion or facet of high impact value with respect to a diametral hit,.and. othersurface portions or facets of high impact value with respect to'offset hits. In either type of hit, the construction is such that the shock of the impact is transmitted to the body of the dome with the result that the dome will tend to fracture along one or more of the lines of potential frac ture, and in the case of the arrangement of FIGS. 10 and i 'It has been found that when the surface irregularities provided by the

depressions

15, 27, 31, or 35 are confined to the dome, the trajectory of the target is not adversely aifected, as it would be if the

peripheral surfaces

13a and 14 of the: rim 10 were provided with similar aspressions. Tests have indicated that increased accuracy in throwing the target is obtained with targets manufactured in accordance with my invention, as a result of which it appears that the dome depressions materially stabilize the trajectory of the target.

In some instances, such as encountered in skeet shooting, a pellet may engage the target at the concave underside of the dome. Here, the glancing off problem is not encountered in the same sense, but nevertheless the

lines

25 or 37 of potential fracture tend to cause a substantial fragment of the target to fly outwardly, thus providing a visual indication which can be scored 'as a hit. The present application is a continuation-in-part of my earlier application, Serial No. 37,910, filed June 22, 1960,

non/abandoned. V

,In the enlarged sections of FIGS. 9 and 11, it will be understood that the

walls

32 and 34 of depression 31, and'the

cylindrical wall portions

38 and 39 of the depression 35 are parallel to the spinning axis of the target, the views being taken when the target is in an inclined position, similar to FIG. 2. I

Although only preferred embodiments of my invention have been shown and described herein, it will be understood that various modifications and changes may be made in the constructions shown without departing from the spirit of my invention as pointed out in the appended claims. 1
