Application June 25, 1945, Serial No. 601,477 1 Claim. (Cl. 193-40) 1 This application relates to a ball holding and release mechanism for games or the like. Such a mechanism holds balls from rolling down a track, and may be operated by the insertion of a 2 is formed as shown to provide a stop for the bar I2 under the tension of the spring I5. It will be observed that in a cabinet or other construction having an opening adapted to be‘ coin into a coin receiver so that the mechanism moves to release the balls which are thereupon closed by the closure panel I, the electromag net portion of the mechanism herein disclosed free to roll down the track. will be within the closed cabinet and the only ex The unitary ball holding and release mech posed portion will be the gate I3 and the holding anism of my invention is illustrated in the ap bar I2. pended drawing. In the drawing, 10 It will also be observed that the unitary mech Fig. 1 is a front view of the mechanism; anism herein disclosed can be inserted into a cab inet and mounted on a portion thereof as a unit Fig. 2 is a top plan view; and Fig. 3 is a left end view. The drawing shows a cabinet wall A having a tunnel or track B, whose wall C has an opening D, normally closed by a closure panel I. Dia grammatically shown at 2 is a ball, which may roll in the track in the direction of the arrow preassembled so that the mechanism as a unit shown. Projecting rearwardly from the panel is may be mounted in place, by unskilled workers merely by using mounting screws 2I for mounting the closure panel I in its place on the opening of the cabinet adjacent to the track along which roll the balls. The unitary mechanism may be fabricated and a bracket 3 upon which is mounted an electro who need only to mount the closure panel by its magnet 4 whose feed wires 5 are connected to a mounting screws and to connect the feed wires on coin controlled switch and an electric current the magnet to the electrical circuit, which op source, not shown, arranged so that upon the de erates that magnet. posit of a coin, the switch is closed momentarily Similarly, replacement of a mechanism by an so that the electromagnet 4 is energized momen 25 other, for repair purposes, is a very simple matter, tarily. The magnet has a plunger I 0 connected by a wire II to a holding bar I2 which normally forms a stop for the ball holding gate I3, holding the ball gate in the position shown, wherein it blocks the movement of the balls in the direction of the arrow. A stop screw I4 limits the movement of the gate in the direction opposite the arrow shown. A tension spring I5 having one end se cured to the panel and the other end secured to a rod I6 fastened to the holding bar I2 normally pulls the rod I6 and the bar I2 forwardly on the hinge I ‘I which mounts the holding bar I2 and it is the tension of this spring that is overcome by the electromagnet 4. When the magnet is ener gized momentarily, it pulls the bar I2 rearwardly on hinge I‘! and the bar releases the gate I3 which thereupon moves rearwardly on its hinge I8 to permit the balls to roll past the gate and the hold ing bar in the direction of the arrows shown. Since the closing of the switch for the magnet is momentary, as soon as the balls have moved be yond the gate and the holding bar, these are re turned to the positions shown by the spring I5. The panel is provided with several openings I 9 permitting the rod I6, the wire II, and the end 20 of the bar I2 to pass through the panel from removal requiring only the disconnecting of the wires 5 and'the removal of the mounting screws for the panel I. Now having described the unitary ball holding and release mechanism herein disclosed, refer ence should be had to the claim which follows. I claim: A unitary ball holding and release mechanism comprising a panel adapted to be mounted adja ‘ cent a ban track, an electromagnet mounted on one side of said panel, a ball holding gate hingedly mounted on the other side of said panel, a gate holding bar hingedly mounted on the gate side of the panel and having a stop portion passing through said panel to engage the magnet side of the panel, a plunger passing through the panel to connect the magnet to the gateholding bar, a rod secured to the bar and passing through the panel to a point near the magnet, and a spring secured to the magnet side of the panel and to the rod at a point near the magnet for normally biasing the bar into gate holding position, said spring being arranged to be overcome upon energization of the magnet which moves the bar out of gate holding position, and a stop for limiting movement of the gate from the ball release position past the ball holding position under bias of the spring, said panel having clearance openings for the stop por the front or track side thereof to the rear or mag tion of the bar, for the plunger, and for the rod. net side thereof. The end 20 of the holding bar 66 ' ISADORE EDELMAN.
