MISSILE PROJECTOR INVEN TOR. Pad 6. [Egg/am BY ATTORNEYS Hawaii Filed July 5, 1966, Ser. No. 40,747 3 Claims. (Cl. 1245) This invention relates to a novel missile projector, and more specifically to a missile projector generally in the form of a whip by which a missile can be projected great distances.
An object of the invention is to provide a novel missile projector which employs centrifugal force to project a missile.
A further object is to provide a novel amusement device or weapon to project missiles of various forms and sizes.
A further object is to provide a novel form of missile which can be readily attached to, and which can be effectively projected from, a projector of the type utilizing centrifugal force.
Other objects and advantages of the invention will become apparent from the following description of a preferred embodiment thereof, reference being had to the accompanying drawing, in which:
FIG. 1 is a perspective view of a first embodiment of a missile projector according to the invention;
FIG. 2 shows one form :of missile in the nature of a bola;
FIG. 3 shows a second form of missile in the shape of a disc;
FIG. 4 shows a third form of missile in the shape of a ball;
FIG. 5 is a perspective view of the gripper end of a second embodiment of the missile projector;
FIG. 6 is a modification of the connecting portion of the missile of FIG. 3;
FIG. 7 is a modification of the connecting portion of the missile of FIG. 4; and
FIG. 8 is a modification of the connecting portion of the missile of FIG. 2.
Referring to FIG. 1, the numeral 1% designates one embodiment of a missile projector comprising a freely flexible lash 12, a whipstock 14, and a frictional gripper 16 in the form of a cylindrical member having a socket 18 adapted to frictionally engage a projection on a missile as will appear hereinafter.
The lash 12 may be made of any convenient length.
In operation, a missile may be frictionally attached to the gripper. By grasping the whipstock 114 firmly in one or both hands, the projector is swept through the air in the same manner as a whip. Toward the end of the sweep, the projector is sharply decelerated either by abruptly halting the forward movement of the handle 14, or by abruptly reversing such movement, in the same manner as employed in cracking a whip. As the projector is swept forward, the handle is first rapidly accelerated, and as the slack is taken up in the lash 12, the gripper 16 partakes of this acceleration, being swung outwardly by centrifugal force in a relatively wide circle. The gripper soon attains its maximum velocity, the lash assuming the form of a large are which has its concave side facing the rear. As the handle 14 is abruptly decelerated, as indicated above, there follows a gradual de celcration of increments of the lash from the handle toward the gripper. The gripper 16 continues at the same speed but the arc changes its form to a reverse curve or 8 :form shown in FIG. 1, assuming that the lash and gripper are moving downwardly of the sheet. The gripper 16 swings in a circle having its center in the 3,695,867 Patented July 2, 1963 loop A, which loop moves closer and closer toward the gripper. The radius of this circle rapidly decreases, until the forward speed of the gripper is suddenly stopped when the lash becomes taut. As the radius decreases, the peripheral speed and angular velocity increase acconding to the formula in which F is the centrifiuigal force, In is the mass, v is the velocity, and r is the radius. It is generally recognized that the tip end of a whip attains a very high velocity, and there is a theory that the crac of a whip is actually a miniature transonic boom caused by the tip of the whip passing through sonic speed. It is proposed to attach the missile to the gripper with sufiicient frictional resistance to permit the missile to be released when the whip is cracked, that is, when it attains its maximum angular velocity, to project the missile with considerable speed.
The missile may take various forms having means to frictionally engage the gripper 16. It may be solid or hollow, and made of metal, wood, plastic, or any suitable material.
FIG. 2 illustrates a missile in the form of a bola 20 comprising a pair of balls 22 on opposite ends of a line 24. A projection 26 is connected intermediate the ends of the line 24, in the shape of a cylinder adapted to frictionally fit within the socket 18 of the gripper 16.
FIG. 3 shows a missile in the form of a disc 28 having a projection 32 formed by a pair of spaced slots 30 in the periphery of the disc. The slots 30 may be made with a hollow cylindrical cutting tool, or by molding or the like, whereby the side wall of the projection 32 is at least partially a surface of revolution.
FIG. 4 shows a ball-shaped missile 34 having a projection 38 formed by a radially extending annular recess 36. The recess 36 and projection 38 may be made by molding, or by cutting with an annular cutting tool to provide a cylindrical projection.
Instead of providing a socket 18 in the end of gripper 16, as shown in FIG. 1, it is evident that the gripper may be a solid cylindrical member adapted to frictionally engage a socket in a missile.
FIG. 5 illustrates a modified form of projector in which a lash 12' carries, on the tip thereof, a gripper 16 in the form of a cylinder, adapted to frictionally tit within a socket in a missile.
FIG. 6 shows a modified missile 28 of disc form having a radially extending slot or socket 49. The wall of the socket is cylindrical in form to receive the gripper 16'.
FIG. 7 shows a ball-shaped missile 34 having a cylindrical, radially extending, socket 42 adapted to frictionally receive the gripper 16'.
FIG. 8 shows a modified construction of the projection of the missile of FIG. 2, comprising a hollow cylindrical member 26', attached to a line 24', the member 26' having a socket 44 to frictionally receive the gripper 16'.
It is readily apparent that other alterations and modifications can be resorted to without departing from the scope of this invention, and such alterations and modifications are contemplated within the scope of the appended claims.
1. In combination: a missile projector comprising a whip-like member including a freely flexible lash, a whipstock on one end of the lash forming a continuation thereof and a cylindrical gripper on the other end; and a missile having a cylindrical projection, one of said cylindrical members being hollow and telescopically and frictionally engaging the other cylindrical member,
said cylindrical members being the sole means holding said missile on said projector.
2. In combination: a missile projector comprising a Whip-like member including a freely flexible lash, and a Whipstock on one end of the lash forming a continuation thereof; a frictional gripping means on the other end of said lash; a missile in the form of a substantially flat disc, at least one generally radial notch in the edge of said disc; said gripping means frictionally but releasa'bly engaging in said notch.
3. The combination defined in claim 2 wherein said disc is provided with two parallel notches defining a projection therebetween; said frictional gripping means com-' prising an open'ended hollow cylinder telescopically and irictionally embracing said projection.
