snmiora PAIENn-jn JAN 1' 51974 sum aur 3 1 PINBALL GAME BUMPER ELECTRICALLY RESPONSIVE TO BALL IMPACT This invention relates in general to pinball games wherein a degree of skill is required to cause a ball-to impact one or more bumpers for electrically establishing a visible score.
The electric circuit commonly used in connection with prior bumpers is relatively complex and requires the use of relays to energize portions of the circuit that results in operating a score read-out. Furthermore, prior bumpers assemblies were usually circular with a single impact surface around the surface thereof and the ballimpact against the periphery was used to momentarily close an electric circuit for energizing the electric scoring means and other elements, which contact is not always sufficiently conductive to complete the operation of the circuitry.
The above objections and disadvantages are overcome by the provision of the present bumper assembly which includes three main members on the upper side of the pin gam board, the first of which is a pedestal fixed and projecting from the upper side of the board and in most instances has a signal light therein.
Another object of the invention is the provision of a coaxial impact disc normally positioned around the upper portion of the pedestal having a lower surface in the form of an upward sloping frustum of a cone, which frustum is adapted for predetermined vertical reciprocation when struck by the ball.
A further object of the invention is the provision of a second coaxial trigger member extending around the pedestal having an upper surface in the form of a downward sloping frustum of a cone and normally positioned a predetermined distance below the upper impact disc and adapted for tilting movement by the ball when the force of the ball is sufficient to raise the impact disc a predetermined distance.
A further object of the invention is the provision of an electric solenoid for raising an elevator assembly related to the impact discs and the trigger member and restored to a position-holding an electric switch in open position when saidsolenoid is momentarily energized for raising the impact discand the trigger member, which construction is a principal object-of the invention.
These and other objects and advantages in one embodiment of the invention-are described and shown, in the following specification and drawings, in which:
FIG. 1 is a side elevation of the bumper and its control apparatus. a I a FIG. 2 is a top plan view of the bumper shown in FIG. 1 with aportion thereof broken away.
FIG. 3 is a top plan view of a portion of the bumper shown in FIG. 1 with a second portion of the top cover broken away.
FIG. 4 is a cross sectional side view taken through section line 4-4, FIG. 1.
FIG. 5 is a top plan view of the bumper, taken through section line 5-5, FIG. 1.
' FIG. 6 is a cross sectional side elevation taken through section line 6-6, FIG. 3.
FIG. 7 is the same as FIG. 1 prior to the impact of the ball.
FIG. 8 is the same as FIG. 7 followingthe impact of the ball.
FIG. 9 is a side view of the elements shown in FIG. 8 and the solenoid therein energized.
FIG. 10 is a cross sectional side elevation taken through section line 10-10, FIG. 3.
FIG. 11 is a cross sectional bottom plan view taken through section line 11-11, FIG. 1.
FIG. 12 is a side elevation of an alternate board mounting assembly of the bumper shown in FIG. 1 and illustrating the removal of the bumper cap shown by dotted lines.
FIG. 13 is a bottom plan cross sectional view taken through section line 13-13, FIG. 12.
FIG. 14 is a schematic diagram of the partial electric circuit for restoring the bumper elements to their idle position.
Referring to PG. 1, all visible elements of the bumper assembly 2 project above the upper surface of the board 1, which includes pedestal 5, display cap 8, trigger disc 18, impact disc 28 and vertical rods 29.
A cylindrical hole having an axis normal the surface of the board 1 is provided with two counter bores which are adapted to retain a collar 3 having an upper and lower flange resting on the lower circular surfaces of the counter bores. The collar is retained in place by a pair of screws 4 which serve to hold a hollow upward divergent pedestal 5 and collar 3 securely through a pair of opposite cylindrical pillars 6extending from the lower end of pedestal 5, illustrated in FIGS. 1, 3,and 5. The upper end of thepedestal terminates in a coaxial upward extending flange 7 in which the numerical display cap 8 in the shape of a frustum of a cone is positioned within the upper edge thereof and retained by screws 9-9, illustrated in FIG. 3. Thus cap 8, prefera-' bly made of translucent plastic material, may be changed to substitute numbers or other desired data. A channel shaped bracket 10 has three upper ears extending therefrom which are secured to the underside of the board 1 by screws 13-13, best shown in FIG. 11. Again referring to FIG. 1, the lower end of the bracket 10 is formed into a right angled offset to support a solenoid coil 11 with the lower end thereof retained to the offset by a nut 12. The core 14 of the solenoid is positioned for vertical reciprocation coaxial with the collar 3 and pedestal 5. A coil spring 15 around core 14 servesto urge the latter into its upper de-energized position. v
An offset scalloped upward stop for core 14 is provided by sub-bracket 16 secured to the main bracket 10 by screw 17, as shown in FIGS. 1 and 2.
'A circular plastic trigger, disc 18 having an outer downward divergent rim includes a central generally downward tapered stem 19 coaxial with the underside of the disc and projecting therefrom, which stem terminates in a spherical tip 20 preferably made of wearresistant material. The trigger disc is provided with a plurality of clearance holes for a passageway around pedestal pillars 6, for permitting the disc to tilt.
The stem of the trigger assembly is centered through the collar 3 when in idle position with the lower planar surface of the trigger disc 18 positioned a predetermined small distance above and parallel the surface of the board 1 when in idle position. A coil spring 21 around the stem 19 is positioned between the lower surface of the trigger disc 18 and the upper surface of the lower inner flange of the collar 3.
' A second sub-bracket 22 is secured to the under side I of board 1 by a pair of screws 13 for retaining a pair of normally open switch blades 23-24 insulated by spacers 25 and retained by screws 26 to the right angled offset end of the bracket 22. Blade 24 extends outward from blade 23 and has an upstanding cylindrical operator 27, preferably made of wear resistant material, and of predetermined height and positioned coaxial with the stem 19 when in its idle position and the tip 20 resting on the upper surface of the operator 27 for normally holding the switch blades in open position when the bumper assembly is in its normal idle position.
A circular impact disc 28 with a rim in the form of an upward divergent conical shape surrounds the pedestal in equispaced relation and has secured therein a pair of oppositely positioned vertical rods 29-29, which are journalled for vertical reciprocation in like bushings 30-30 through board 1, best shown in FIG. 4.
The lower ends of the rods 29 are secured to a bridge bracket 31 by a nut 32 threaded on each rod, which bridge bracket has a contact edge 33 parallel the board 1 for operating switch blade 24 downward against its normal closing tension. The upper end portion of the solenoid core 14 is secured to the bracket 31 and rods 29 by a transverse member 34 retained between shoulders on the rods 29 and the bracket 31. Another transverse plate 34s has a slot therein for engaging a groove in the upper end portion of the core 14 for securing the core to the member 34. A pair of electric terminals 35-35 are secured to the coil ends of the solenoid. One of the terminals 35 is connected by conductor 36 to the blade 24 and a continuation conductor 36 connected to blade 23, as shown in FIGS. 1 and 2, the operation of which will be hereinafter described.
FIGS. 3 and 4 illustrate the optional use of an electric lamp signal for illuminating cap 8 when desired. A bracket 37 secured within the pedestal 5 retains a socket 38 for a miniature electric lamp 39 which will illuminate a translucent cap 8 when energized. A pair of terminals 40 of the lamp socket 38 project from the pedestal downward through a pair of opposite pedestal pillars 6 for connection to conductors such as 36 and 36s, as illustrated in FIGS. 5 and 10.
An alternate construction is shown in FIGS. 12 and 13 wherein the collar 3 which is in alignment with the principal elements is supported in a relatively large hole in the boardl and secured by an upper standing 41a having a central hole for receiving collar 3 and a mating lower stamping 42a secured to the under side of the board 1 and also having a central coaxial opening for collar 3 which lower plate is held by five screws 13 with corresponding opposite ears a applied to the solenoid holding bracket. A C washer 43a is secured around collar 3 to firmly hold same in secure central relation with respect to stampings 41a and 42a, and provides a single unit bumper assembly.
It is to be noted that screws 29-29 are inserted through the upper flange of collar 3 in opposite direction into the pedestal pillars 6, shown in FIG. 6.
FIG. 14 shows the portion of a schematic electric circuit involving the restoration of the trigger disc with the switch blades 23-24 in open position following the momentary energizing the colenois when the tip of the stem 19 is displaced by the tilting movement of the trigger disc. I
In operation and under the assumption that the bumper assembly is constructed as shown in FIG. 1, with the elements positioned as shown, ball B is in its approach to the pedestal, which will first contact the sloping edge of trigger disc 18 and tilt same, as shown in FIG. 7, which will move the tip 20 of the stem 19 from its rest position on operator 27 and thus permit the normally closed contacts of blades 23 and 24 to close, which will energize the restoring action of solenoid coil 11 at a time period dependent upon the major scoring circuit, not shown.
When the solenoid coil 11 is energized, the core 14 will be withdrawn downward against the restraining action of the spring 15 and move the rods 29 and the impact disc 28 downward and automatically restore the blades 23-24 to their normal open position. The sloping side of the impact disc will then force the ball B outward away from the bumper assembly and position the tip 20 and the trigger disc 18 to its normal idle position by virtue of spring 21, as shown in FIG. 8, and open the switch blades 23-24, which will permit the bumper assembly to assume its original position, as shown in FIG. 1.
It is also apparent that FIG. 1 is a dual assembly unit applied to the board 1, whereas the construction shown in FIG. 12 is a unit assembly which avoids the possible error of alignment of the placement of the screws 13.
It is also apparent that prior to the restoration of impact disc 28 to its upper idle position it is possible with a delayed electric action to prevent any further impact of a ball B against the trigger disc 18 for a particular type of game.
It is to be understood that certain modifications in construction are intended to come within the teachings and scope of the above specification.
