DA L E KR USE CHARLES H. HARD/N BY Mjma THEIR AGENT GAME APPARATUS This invention relates generally to game apparatus and more particularly to such an apparatus for two players in which each of a pair of seesaws mounted intermediate the ends of an elongated supporting base are provided with dual tracks, one of which is provided with a lighter ball-containing 'capsules and the other is provided with a weighted or steel ball. The capsule-containing tracks are aligned with a win pocket in the end of the base away from each player and each end of the base is provided with two spring projectors in alignment with and projecting within the ends of the steel ball tracks. Each player by projecting his weighted ball to the end opposite him tilts his tracks toward his opponent so that the capsule will move by gravity down its track to the win pocket. Simultaneously each player must try to offset such move by his opponent by attempting to return the steel ball'to his opponents end to reverse the tilt of the seesaws and reverse the motion of the capsule toward the win" pocket.

The primary object of the present invention is thus to provide a novel game apparatus which requires skill and coordination and which' is therefore of continued interest to the players.

An important object of the present invention is to provide a novel game apparatus of the type described which is-strong and rugged in use and susceptible of ready and economical manufacture. a

Other objects and advantages of the present invention will become apparent during the course of the following description.

In the drawings l have shown one embodiment of the invention. In this showing:

FIG. 1 is a top plan view of the game apparatus comprising the present invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is an end elevational view thereof looking from the left with the seesaws in the position of tilt shown in FIGS. 1 and 2;

FIG. 4 is a transverse vertical sectional view to an enlarged scale taken on the line 4-4 of FIG. 1;

FIG. 5 is a fragmentary, longitudinal, vertical, sectional view taken on the line 5-5 of FIG. 1;

FIG. 6 is a fragmentary, transverse, vertical sectional view taken on the line 6-6 of FIG. 5;

FIG. 7 is a fragmentary, transverse, vertical sectional view taken on the line 7-7 of FIG. 5;

FIG. 8 is a sectional view of a ball-containing capsule; and

FIG. 9 is a transverse, vertical sectional view taken on the line 9-9 ofFlG. 2.

Referring to the drawings, the game apparatus of the present invention comprises an elongated base 14 having end portions A and B connected by inverted U-shaped side rails 16, a pair of identical seesaws l8 and 24 pivoted at their miclpoints centrally of the base 14 as will be explained, a pair of

steel balls

21 and 27, and a pair of

capsules

22 and 28 each of which contains a ball 30 of lighter weight (taken with the capsules) than the steel balls.

While the base and the seesaws may be formed of any desired material, they are preferably formed of polystyrene.

The seesaws l8 and 24 are respectively provided with dual tracks, one-31,37-for the

steel balls

21 and 27, and the other -32,38for the

capsules

22 and 28. The

tracks

31 and 37 are closed at each end by walls 34 which are provided with apertures 35 extending into the bottoms of the tracks as at 36. These apertures (FIG. 1) enable the ends of the seesaws to clear the plungers of the spring projectors which extend beyond their housings as will be described. The

tracks

32 and 38 are closed at one end and open at their other ends as at 33.

The seesaws l8 and 24 are each provided with a plain trunnion 40 and a flanged trunnion 42 at their midpoints by which they are pivotally mounted in outer stanchions 44, and an inner stanchion 46 having a cap 48 (FIG. 4), the three projecting upwardly from a crossmember 49. The trunnions 40 are received in circular apertures 50 while the flanged trunnions 42 are placed in semicircular recesses 52 which cooperate with similar recesses 54in the cap when seated and secured to retain the

seesaws

18 and 24 secure in their pivots.

- A pair of spring projectors 56 having operating handles 58 and steel ball engaging plungers 60 is mounted on each of the base ends A and Bin alignment with and closely adjacent to the ends of the

tracks

31 and 37. The projectors are slidably mounted in recesses 62 in

pillow blocks

63 and 64, the springs acting between the latter and a collar 66 fixed to the plunger 60. (FIGS. 5, 6 and 7).

The collars 66 of the four spring projectors 56 are provided with upstanding scale marking pins 68 which project through slots 70 in housing members 72 which enclose the pairs of projectors at each end of the base and retain them in position.

Numerals 74 are placed along the slots 70 as scale markings to act as a guide for the players of the game apparatus.

As seen in FIGS. 1 and 9, a storage bin 76 for the steel balls and a slot 78 with numerals along it and a marker 80 moveable in it is arranged in both of the rails 16. The upper surface of the housing 72 at the base end A is provided with a win" pocket 82 while the housing at the base end B has a "win" pocket 88.

In the operation of the game apparatus, two players position themselves at opposite ends thereof and each tilts the seesaw on his left downwardly toward him. At this time, a steel ball (27,21) is placed in the lowered ends of the

tracks

37 and 21 respectively and a .capsule (28,22) is placed in the lowered closed ends of the

tracks

38 and 32.

The object of the game is for one of the players to get his capsule into the win pocket of the other player and to prevent his opponent from doing likewise. Thus, the player at end A may project his steel ball 27 with his spring projector 56 to the B end of his track 37 where the weight of the steel ball will reverse the tilt of the seesaw 24 and cause the capsule 28 to tumble end over end down the chute 38 and through the open end 33 into his win" pocket 88 in the base end B. Similarly, the player at end B may project his steel ball 21 with his spring projector 56 to the A end of his track 31 where the weight reverses the tilt of the seesaw I8 and causes the capsule 22 to tumble end over end down the chute 32 and through the open end 33 into his "win" pocket 82.

Either player may prevent the entry of his opponents capsule into the win" pocket by the timely use of his other projector 58-which is on the right-hand side of his end. For example, the player at the end A projects his steel ball 27 toward the end B to tilt the seesaw 24 downwardly toward the end B to effect movement of the capsule 28 toward his win" pocket 88. After taking an equivalent offensive action, the player at the B end waits until the steel ball 27 lies against the end wall of the track 37 and then uses his projector on the right-hand side to project the steel ball 27 back to the end A and by its weight, again reverse the tilt of the seesaw 24 and the direction of tumbling of the capsule 28 before it reaches the win" pocket. The recourse of the player at the A end of the base is, of course, to again initiate his attack set forth above.

while defending against any entry into his win pocket. The number of games won by each player is recorded by either player by moving the market 80 in its slot 78.

It will be appreciated that a marble or a lighter weight steel ball can be substituted for the capsules to afford a variation in the game, such particular variation effecting a real speedup in play due to impact and lack of inertia of the marbles. Essentially, this substitution has been found to be undesirable. However, it is to be understood that the terms, steel ball" and capsule" as used in the specification and claims are intended to include marbles, weighted balls, or any members capable of rolling or sliding down the tilted seesaws as long as the projected members are heavier than the members intended to enter the win" pockets.
