REPROJECTING BALL BUMPER Filed Nov. 14, 1963 2 Sheets-Sheet l REPROJECTING BALL BUMPER Filed Nov. 14, 1965 2 sheets-sheet 2 INVENTORS- A/Paw d. 55mm/ effi J5 /m/ L. ,SE/ pew United States Patent 3,298,691 REPROJECTING BALL BUMPER Harold 0. Berninger and Herman L. Seiden, Chlcagp, Ill., assignors to Lion Manufacturing Corporation, Chicago, Ill., a corporation of Illinois Filed Nov. 14, 1963, Ser. No. 323,660 4 Claims. (Cl. 273-129) The invention pertains to improvements in ball-deflecting devices used in ball rolling games, commonly called bumpers, and particularly to the movable types which are power-driven to impart a blow to a ball under certain conditions responsive to ball action or player-controlled means.
The presently disclosed improvements provide a new actuating mechanism and circuit therefor adapted to use with a known type of bumper which is in the form of a cantilever arm pivoted at its supporting end so as to swing in a horizontal plane and impart a blow to a ball impinging thereagainst in the course of play, together with improvements in the construction of the bumper members to simplify assembly, servicing, and replacement of the cantilever bumper arm and associated parts.
Other and more detailed aspects of novelty and utility pertain to details of the preferred embodiment described hereinafter in view of the annexed drawing in which:
FIG. 1 is a side elevation of the bumper and actuating mechanism mounted on a sectionalized fragment of a ball-rolling board;
FIG. 2 is a top plan view of the actuating mechanism and control switch;
FIG. 3 is an exploded perspective of the cantilever bumper assembly and pivot shaft;
FIG. 4 is a cross-sectional detail of the bumper body taken along lines 4 4 of FIG. l;
FIG. 5 is a fragmentary top plan view of a ball-rolling playfield showing two of the bumpers and appertaining control switches;
FIG. 6 is a circuit diagram.
Referring to FIG. 1, one of the novel bumpers is shown mounted on a ball-rolling board or playfield 10, the principal body portion 11 being in the form of a somewhat narrow and elongated plastic shell having a closed and rounded dome portion 12 beneath which is a rubber or like resilient rebound band 13, the foot portion of the body or shell being spaced, as at 14, slightly above the playeld for clearance so that the bumper may swing about an axis Z-Z.
As viewed in FIG. 3, the bumper body comprises a molded shell having an open bottom communicating into a hollow interior cavity in which are two post portions 17, 18 both having a bore, the bore of post 17 being adapted to receive a screw 19 and the post 18 being adapted to receive the reduced end 21 of a spindle 2@ having a metal support and closure plate 22 fixed thereon and of a shape to t into the bottom opening of the bumper shell.
The spindle plate 22 enters the body cavity to a depth determined by three lands 23A, -B, -C, formed by molded projections from the inner wall surface, FIG. 4, also. Snap-action means for releasably retaining the spindle plate in the cavity, and in firm connection therewith, comprises a set of narrow, shallow ribs 25 closely adjacent the rim or lipof the shell, such that the periphered margins of the spindle plate may be forced therepast and seated on said lands, the relatively thin plastic walls affording suicient yieldability to eifect a snap-in and snap-out action for said spindle plate. The screw 19 further secures the snap-in assembly against the fairly severe forces occasioned by impact of steel playing balls against the cantilever suspended assembly as it is depicted in FIG. l.
3,298,691 Patented Jan. 17, 1967 ICC Mounting of the bumpers on the playeld, FIG. l, is effected by means of a bushing 26 set in the board and seating the spindle 20, which is secured on the underside of the board by means of a collar 27 provided with suitable set screws 28 (FIG. 2 also).
Means for actuating the bumper in a swinging motion about the axis Z-Z comprises (FIG. 2) a bell-crank type Iof lever 30 secured to the collar 27 and therefore rotatable with the bumper spindle through a range determined by a stop cleat 31 fixed on a mounting plate 32 adapted to be secured by screws to the underside of the playboard.
Pivotally connected, as at 33, to the bell-crank is the end of a solenoid plunger 34 adapted to be attracted against the action of a restoring spring 35 into the bore of a solenoid 36 having a special winding to be eX- plained.
Carried on said mounting plate 32 is a leaf switch 37 having normally closed blade contacts 38, 39, the end of the latter projecting into the path of a stud 40 on the bell-crank lever such that when the lever is swung from the normal position shown in FIG. 2 to the dotted-line position, the switch blades will be separated to the opencircuit condition, and this movement of the bell-crank by the solenoid will pivot the bumper spindle about axis Z-Z and swing the cantilever bumper into the dottedline position seen in FIG. 5.
In one of the playing or game arrangements possible with the novel bumper, such -as illustrated in FIG. 5, the normal position of the cantilever arm may be chosen to lbe such that a ball B following a path designated by arrows a will roll along the length of the bumper and into a ball eXit at 42.
But if the actuating means or solenoid is energized at the right instant while this ball is travelling against or near the free end of the bumper 11A so that the latter swings abruptly into dotted-line position, the ball may be reprojected and caused to follow any of several new courses such as b designated by the arrow b, c, depending upon where the ball happens to be at the instant the bumper begins its reprojecting movement.
The skill and amusement aspect of the game are thus eX- panded by providing a plurality of the novel bumper units and manual control switches operated by the player at Will to determine new and varied possibilities for reprojections of the ball.
In the arrangement illustrated in FIG. 5 two of the been provided at the lower end of the usual inclined ballrolling board, together with separate control switches 45A, 45B, situated in the sidewalls -of the game for lactuation respective-ly by push-buttons 46A, 46B by the right and left hands of the player.
The two bumper control switches 45A, 45B are connected in a control circuit such as depicted in FIG. 6 and adapted to connect power respectively to the special solenoid windings for each bumper.
The solenoids indicated generally at 36 in FIGS. l and 2 are especially wound to have split or dual windings, such as portrayed at 50A, 50B, or 51A, 51B, respectively, in FIG. 6, these dual windings for each solenoid being connected in series at their respective joint terminals 52A and 52B, and the two solenoid winding units likewise being connected in series at their terminals 53A, 53B.
The power source shown may be the secondary 47 of a transformer, `one terminal 48 of which connects with the joint terminals 53A, 53B, and the remaining terminal 49 of which transformer winding connects via conductors 55, 56A, 56B through the normally open manual control switches 45A and 45B to one contact 38A and 38B `of the two bumper winding control switches 37A, 37B, the said conductors 56A, 56B also respectively connecting to terminals 57A, 57B of the respective solenoid high-resistance windings, whereas the respective remaining contacts 39A, 39B of the winding control switch each connect via conductors 58A, 58B to the yseries connected winding terminals 52A, 52B.
Thus, each winding control switch 37A or 37B normally shunts out the appertaining low-current or high-resistance winding, so that the voltage applied by closure of either manual switch 45A, 45B will energize the highcurrent (low resistance) winding so as t pull in the solenoid plunger positively and with considerable energy and swing or ilip the appertaining bumper smartly to give the ball a very substantial reprojecting blow.
However, as the bumper moves into full stroke position, the bell-crank will press the corresponding switchoperating stud against the corresp-onding switch blade 39A or 39B and open such switch to remove the short-circuit from the corresponding higher-resistance winding and thereby cut the latter into the circuit to drop the current to a safe level sufficient to hold the solenoid plunger reliably in attracted position, without over-heating the solenoid winding in case the player desires to hold the control button down for any length of time, as it is intended he may do.
It will be understood that one or both of the bumpers shown in FIG. 5 may be held indefinitely in the operated or dotted-line position by holding the appertaining manual control switch closed; and the player may do this in anticipation of a played ball rolling down against the held bumper which will trap or stop the ball and permit the player to hold the same indefinitely until the player does one of two things: either releases the bumper to free the trapped ball, or momentarily releases the bumper to permit the ball to 4gravitate `slightly toward the free end of the bumper, and then quickly closes the control switch again to flip the ball back onto the field in a `direction which will be largely determined by how far the player permits the momentarily released ball to move, during its temporary freedom before the control switch is reclosed, it being possible by skillful judgment and timing to procure a variety of reprojection patterns or trajectories by the sort of manipulation described, and thereby to enhance the playing action as to amusement, exercise of skill, and variations in scoring results.
