HOOKER Feb. 4 1964 LAMP BANK AND SELECTIVELY SHIFTABLE CONTACT MEANS 4 Sheets-Sheet 4 Filed Dec. 1, 1958 w hsusu u uwok United States Patent 3,126,657 LAMP BANK AND SELEQTIVELY SHTFTABTLE CSNTAQT MEANS Donald E. Hooker, Wilmette, 13L, assignor, by mesne assignments, to Lion Manufacturing Corporation, a corporation of Illinois Filed Dec. 1, 1958, Ser. No. 777,272 Claims. (til. 346-378) This invention relates to improvements in a shiftable lamp bank system and driving means therefor useful in conjunction with score-indicating mechanisms, display devices, annunciators, and the like, and in its broadest aspects, the novel lamp system includes sets of linearlyarranged lamp sockets each having aligned in parallel relation therewith a contact carrier which is shifted back and forth relative to stationary contacts on the sockets, whereby the lamps may be cut in and out of circuit.

A further feature of the mechanism is the provision of shiftable number panels and motor driven means for shifting the same in step with a corresponding contact carrier.

Another feature is the provision of a motor drive means having a simple motor common to a plurality of lamp sets and associate number carriers, and selectively operable clutch means for causing a shift of a desired contact carrier and number panel.

Still further objects relate to details of construction and operation of a novel lamp socket and indicia-panel carriers and certain contact means and slide-bed means therefor, all of which will appear more fully as the following description proceeds in view of the annexed drawing, in which:

FIG. 1 is a rear elevation of a selective drive mechanism and shiftable lamp bank assembly;

FIG. 6 is an enlarged elevational detail of one of the clutch control discs looking along lines 6-6 of FIG. 5;

FlG. 7 is a top plan view of one of the lamp contact carrier strips;

FIG. 8 is an elevational view of the lamp socket strip of FIG. 7;

FIG. 9 is an enlarged cross-sectional detail through the lamp-socket and contact carrier assembly taken along lines 9-9 of FIG. 3;

FIG. 10 is a partial front elevational view of the apparatus shown in FIG. 1, parts being broken away.

One commercial embodiment of the invention is adapted to use in a Bingo type of amusement game having changeable number cards C C arranged on a glass score panel 23 shown in FIG. 10.

Each score card has located behind the glass panel on which it is delineated five parallel, horizontally-shiftable, translucent indicia or number-bearing panels 2t each panel being slidable in its own track 21 attached to the front face of a lamp backboard 22 located behind said glass panel, the latter also having delineated thereon various other indicia and legends relevant to the playing or" the particular game in question.

Each of the so-called Bingo cards C C comprises 25 scoring squares laid out in square array with appropriate score numbers made to appear in each square. Scorin" in this type of game is achieved by getting a complete set of five numbers in a straight line, either across, upward, down or diagonally, on a single card. In the present embodiment, electric lamps will be variously i1- 3,120,657 Patented Feb. 4', 1964 ICC luminated behind each scoring number as a result of playing the game, and the illumination of five lighted lamps in a line, as aforesaid, will achieve a winning score.

The score numbers displayed on the shiftable corner panels 2b are scrambled as to numerical sequence or value, and by sliding these panels back and forth the number pattern can be varied for purposes having to do with the playing of the game and operation of game mechanisms not elaborated upon herein, since the present claims of novelty relate more particularly to the score-display apparatus and means for shifting the number carriers and changing certain lamp contacts to alter the scoring set-up, as will now more fully appear.

FIG. 1 shows the reverse side of the score backboard 22 to which is afiixed the shiftable score mechanism including five slide beds 30 in each of which is a slidable contact carrier or slide strip 443 movable back and forth in the appertaining slide bed by means of a long crank wire 5t} having one end 51 offset to enter a lug hole 44X in the corresponding contact slide strip 44 the opposite end 52 of each said wire being offset for crank engagement with a cleat 5% on one of a plurality of corresponding clutch discs 53 rotatable on clutch spindle 54 journalled on the chassis plate 55 of the drive and control unit.

A single motor 56 with built-in reduction gear (FIG. 1) is adapted through motor gear 57 (FIG. 4) to drive a train of clutch gears 58, of which there are five, one for each of five clutch discs 53.

The motor 56 runs continuously and thereby rotates all five of the clutch spindles 54 continuously; however, as depicted in FIGS. 5 and 6, the clutch discs 53 float on their respective spindles 54 as long as they are latched-in or restrained, but when released from latched condition, a clutch plate 53A, fast on the spindle bears against the disc 53 and turns the latter owing to pressure set up by a spring 59 bearing against a clutch presser plate 54A (FIG. 5).

Normally, each clutch disc 53 is latched at rest by its own electromagnetic latch means (FIG. 1) including a latching armature having thereon a latching lug 70 adapted to seat in any one of four peripheral latch notches 53X (FIG. 6, also) spaced about the corresponding clutch disc. Energization of the corresponding electromagnet 72 withdraws the latch lug and permits the clutch disc to be driven through the appertaining slip clutch means 53A, 54A, 59, with a resultant displacement of the corresponding crank wire 5%, and the associated contact slide 45?, as well as the corresponding translucent number strip Ztl, this latter action being achieved by having the outer offset end 51 of each crank wire extend through a long horizontal slot 13 in the backboard 22 and enter a coupling hole 19 (FIGS. 2, 10) in the corresponding number strip 20. Thus, as each crank wire reciprocates its associated contact strip 4b it shifts the corresponding number strip 29 in step therewith.

The aforesaid clutch-released shifting of any contact carrier strip 49 and its associated number strip 26 will change the number pattern for the score cards C C as well as circuit connections needed to effectuate the scoring operation of the changed cards.

According to the construction of the contact carriers, as depicted in FIG. 3, the strips id are formed of insulating material, such as Bakelite, and suitably punched at intervals to receive the lug t ails 41 of wiper contact fingers 42 riveted in place, as at d3 (see FIG. 9, also); Angle brackets 44 (FIGS. 3 and 7) are attached to each strip at opposite ends, each bracket having a pair of pierced lugs 44X to receive the traversing offset parts 51 of the crank wire.

As shown in FIG. 7, each contact carrier 40 has its complement of contact wipers 42 pitched reversely from 3 its mid point, half one way and the remainder oppositely, to balance the load better in reverse travel.

The slide bed 39 (FIGS. 8 and 9) comprises two formed stampings 30A, 39B, assembled by screws 30C whereby to form a long channel assembly with formed slide grooves 30X at the outer open side thereof, and a bottom or back wall 30AZ, punched at intervals along its length to receive lamp sockets 45 which in turn are secured to an insulating strip 46 (FIG. 9) with connecting tails 45A projecting as one terminal of the corresponding socket. Connection to the remaining (center) terminal of each socket can be effected through one of the carrierstrip spring wiper fingers 4-2 by engagement thereby with a contact piece 47 (FIGS. 8 and 9), carried on a companion insulating strip 43 and projecting through slots in the latter and strip 46 into contact with the central terminal of the lamp in the corresponding socket 45.

All lamp terminal lugs 45A will generally be connected to a common power terminal while each of the wiper finger lugs 41 will be connected to other switching mechanisms (not shown), such as relays, stepping switches, or commutating switches, which will selectively control the completion of power circuits through the various wiper fingers 42 to different lamps, depending, for instance, upon scoring operations in the particular game apparatus with which the shiftable score cards may be employed.

In general, the shifting of carrier strip contacts 42 will serve to connect one or another lamp in each set to different energizing and control circuits (not shown) which, if the latter become effective as a result of playing the game, will cause the wiper-connected lamp to be energized.

It will be apparent that a wide choice of schemes of electrical operating connections may be made to the several lamp terminals 4145A; and a variety of operating and control connections may be made to the electrically actuated and controlled driving motor and clutch means 56, 72, to produce different light-up and display effects from the several sets of lamps.

The present disclosures relate to subject matter of analogous character disclosed in applications Serial Nos. 478,992, now Patent No. 2,932,517, April 12, 1960 and, 570,931 new Patent No. 3,034,790, May 15, 1962 and, apart from obvious structural and functional differences, distinguish over the prior improvements by making possible a considerably wider scope of permutations or combinations of displayed score numbers and lamp circuits with less equipment.
