United States ice BA'ITING PRACTICE DEVICE Mortimer L. Chanko, South Orange, N.J., assignor to Educational Products, Inc., Newark, N..l., a corporation of New Jersey Filed Apr. 30, 1959, Ser. No. 810,167

4 Claims. c1. 273-26) The present invention relates to a batting practice device.

More specifically, the present invention relates to a batting practice device wherein baseballs may be successively discharged under the control of the batter, one at the time, and which discharged balls follow a path simulating that of a pitched ball which passes the strike zone of the batter.

It is accordingly an object of the present invention to provide an improved batting practice device of generally improved and simplified construction.

Another object of the invention is the provision of a batting practice device having means for discharging the balls from a magazine, one at the time, under the control of the batter, and having means for imparting to the discharged balls a movement along a path which simulates that of a pitched ball and which passes through the strike zone of the batter.

Another object of the invention is to provide a unitary wire-shaped formation releasably secured to the discharge opening of a magazine for guiding the discharged balls and for providing gate means so as to discharge one of said balls at the time.

Another object is to provide a Wire formation for guiding balls discharged from a magazine along a predetermined path and to impart to said discharged balls a trajectory through the air which simulates that of a pitched ball, said wire formation having gate means normally biased to prevent the discharge of said balls and being movable to a position in which said balls may be discharged.

Another object is to provide a wire formation for guiding balls discharged from a magazine along a predetermined path and to impart to said discharged balls a trajectory through the air which simulates that of a pitched ball, said Wire formation having gate means normally biased to prevent the discharge of said balls and being movable to a position in which said balls may be discharged, said gate means including a pair of prongs extending downwardly into the magazine adjacent the discharge opening thereof and normally biased so as to prevent the discharge of said balls.

The above and other objects, features and advantages of the present invention will be more fully understood from the following description considered in connection with the accompanying illustrative drawings.

In the drawings:

Fig. 1 is a plan view of a wire formation in accordance with the invention;

Fig. 2 is a sectional view, on a larger scale, taken along line 22 of Fig. 1;

Fig. 3 is a view, partly in section, taken along line 3-3 of Fig. 2;

Fig. 4 is .a View taken along line 44 of Fig. 2; and

Fig. 5 is a sectional view taken along line 5-5 of Fig. 2.

Referring now to the drawings, the batting practice device of the present invention comprises in .general a magazine 44 provided at one end thereof with a forma tion 42 which defines a guideway or runway for the balls B in the magazine and which also defines a gate or stop 60 for said balls. The magazine 44 is mounted in a tilted position thereof, as shown in Fig. 2, so that the balls may be gravity fed toward the formation 42 when stop 60 is moved out of the path of said balls. Any suitable mounting or support may be provided for mounting magazine 44 in said tilted position thereof. For example, and as shown in Fig. 2, there is provided a standard 20 at the upper end of which there is provided an annular or ring-shaped member 24 which is adapted to releasably hold the magazine 44. Ring 24 is mounted for pivotal movement about standard 20, by means of bolt 58, so that it may be adjusted so as to provide any desired angle of inclination of the magazine 44.

Magazine 44 comprises a tubular member open at the opposite ends thereof to define a loading opening (not shown) and a discharge opening 45. At the discharge end of magazine 44 there is provided the previously mentioned formation 42 which defines simultaneously the stop meansdtl for preventing the discharge of the balls through opening 45 and the runway for guiding the movement of the discharged balls from the magazine 44.

Wire formation 42 comprises a pair of longitudinally extending wires .46 and 48 having

intermediate portions

46a and 48a, respectively, held in parallel spaced relation by means of transversely extending downwardly

curved parts

50 and 52 suitably secured thereto, as by welding. Extending from the outer ends of

portions

46a, 48a, respectively, in converging relation, are wire portions 46b, 48b, respectively. Wire formation 42 terminates at one end thereof in upwardly curved parallel spaced end portions 46c, 480, respectively, interconnected by transversely extending part 54. From the inner ends of

portions

46a, 48a, respectively, wire formation 42 extends to define conver

ing wire portions

46d, 48d, respectively, which are angularly related to intermediate wire portions 46a, 4811, respectively. Wire formation 42 terminates at its inner end with converging wire portions 46:2, 482, respectively, the latter terminating in hooked portions 56.' Hooked portions 56 are wrapped around the bolt 58 which pivotally mounts ring-shaped members 24 onto standard 20, to thereby releasably and resiliently mount wire formation 42 on magazine 44 for pivotal movement relative thereto. Wire formation 42, by its resilient mounting, is normally biased in the position shown by the full lines in Fig. 2.

Wire portions 46a-d and 48a-d cooperate to define a guideway or runway for the balls B which are discharged from magazine 44-, and impart to the discharged balls a trajectory which simulates the path of a pitched ball, as will hereinafter be discussed. Provision is made for releasing only one ball at the time from magazine 44, which ball will follow a predetermined trajectory set therefor. Toward that end, wire formation 42 is provided with a gate 69 secured thereto, for movement in unison therewith. Gate 69 comprises a wire formation having a base 62 which may be welded to wire formation 42 at the junctions of portions 46d46e and 48d48e, respectively, as best shown in Figs. 3 and 5.

Side parts

64 and 66 extend upwardly from the opposite ends of base 62, respectively, then curve inwardly, and terminate in

prongs

68 and 70, respectively, which extend downwardly into magazine 44 through apertures 72 and 74, respectively, provided therefor.

In the normal position of wire formation .42 (shown by the full lines in Figs. 2 and 3), gate is adjacent the discharge opening 45 of magazine 44,

prongs

68 and 70 extend a substantial distance inwardly of magazine 44 to prevent the discharge of balls B therefrom, base ,62 is spaced a small distance from magazine 44, and the curved portions of gate 60 engage the magazine. The device is now ready for its utilization. To operate the device, the batter raises the free end of wire formation 42, against the resilient action thereof, to the position shown by the dashed lines in Figs. 8 and 9. This removes

prongs

68 and 70 from the path of the lowermost gravity biased ball B, thereby enabling the latter to rollout of magazine 44, between the spaced

wire portions

46d, 48 e and 46a, 48a, which define a guideway for the downward movement of said ball. It will be understood that the batter raisesthe wire formation for a fractional period of time to permit only one ball to be discharged from the magazine 44, after which he places the bat on his shoulder in position for batting practice. Due to the resiliency of wire formation 42, upon removal of the bat, formation 42 will return to its lowermost position shown by the full lines in Figs. 2 and 3 in'which prongs 72 and 74 are in position to prevent the next ball from being discharged. In the. meantime, the ball B which has just been discharged rolls down the guideway, picking up. momentum, and the curved end portions 460-480 cause the ball to take on an upward motion as it leaves wire formation 42, to follow a path or trajectory in the air which is substantially similar to that followed by a pitched ball and which passes'through the strike zone of the batter who is in position to swing his bat for his batting practice. The same steps may now be repeated to discharge the next ball from magazine 44 which will follow substantially the same path previously'described.

, .It will be apparent that the height of magazine 44 as well as the angle of inclination thereof can be adjusted to any desired amount so that the balls which are discharged follow a predetermined path asmay be desired by the batter. It also be noted that when wire formation 42 is' raised to dischargea ball B, base 62 will engage magazine 44 and limit the upward movement of the wire formation so as to prevent the complete removal of prongs 72 and 74 from the magwaz'ne, while still permitting the discharge of a ball;

' Thus it is seen that the batting practice device described above is'eminently well suited to accomplish the objects of the invention.
