Laserson, Scarsdale, N.Y., assignors to American Machine & Foundry Company, a corporation of New Jersey Filed May 12, 1965, Ser. No. 455,123 13 Claims. (Cl. 359) ABSTRACT OF THE DISCLOSURE The method of scoring a simulated bowling game comprising providing a player with frame by frame pinfall results, limiting the pinfall of each succeeding frame accessible to a player until the pinfall for a preceding frame has been scored and entered, and displaying to said player the correct pinfall for each frame in successive frame by frame relationship after said player has scored each prior frame, whereby said player can check his score in each frame against the correct score for each frame, and if in error correct his score.

This invention relates to the game of bowling and more particularly to a method of and apparatus for facilitating the teaching of score keeping for the game of bowling.

The game of bowling like other individual and team sports is subject to a number of prescribed scoring rules which must be applied properly in order to obtain the correct score for each game bowled by each player. Unlike some sports, however, proper scoring is an essential and integral part of bowling which cannot be enjoyed to its full extent unless each bowler understands the rules of scoring.

To those who are uninstructed or not conversant with the game, scoring may appear to be a complicated and complex matter. Therefore, bowlers, especially beginners or novices are apt to become confused and get annoyed or irritated when they find that they are unable to score a game properly. Even those who are-fairly conversant with the rules of scoring are liable to make a mistake which can result in confusion and arguments among players and those who are keeping score.

Beginning and novice bowlers usually learn scoring from other bowlers which is embarrassing to many individuals, and/or by studying written instructions, such as published by the American Bowling Congress. Even when properly applied, these procedures often lead to a faulty understanding of bowling scoring procedures which interferes with the enjoyment of the game. Even if scoring rules are fully understood scoring practice is desirable in order to insure the proper application of rules of scoring at all times. The present invention provides a novel method for teaching the proper scoring of a game and apparatus for making this possible. The result is that the bowler acquires a full understanding of bowling scoring techniques and, therefore, becomes adept in keeping score. The individual who, because of lack of understanding in scoring, may have hesitated to participate in and enjoy this great game and who now, in using the apparatus involving the invention will find it possible to readily learn and understand scoring techniques, will acquire an interest in the game. In addition, the ability to score properly obviously increases both interest in, and enjoyment of bowling even for those who do bowl.

It is the object of this invention to provide a novel method of and apparatus for the teaching of scoring the game of bowling.

The invention also consists in the provision of a novel method of providing instruction for scoring the game of bowling and apparatus having means which displays approved scoring rules for the game of bowling and mechinvention;

anism which affords a bowler an opportunity to score one or more games involving the application of these rules.

It is a further object of the invention to provide the bowling scoring trainee or operator of the apparatus embodying the invention on his demand with numbers representing the pinfall in each successive frame of one or more simulated bowling games, without the total frame to frame score, and also providing him with means which, if he has entered the pinfall results of each frame and totaled them, can be compared in order to inform him whether or not he has accurately scored the pinfall results of each frame.

A further object of the invention is to provide an apparatus in which the player is provided with the correct score corresponding to previously presented pinfall numbers which have been entered on a score pad as each successive frame of a simulated game of bowling is made known to the player and totalized such that he may check his scoring procedure and ascertain if the score he has computed and entered corresponds with the correct score made available to him for this purpose.

The invention further contemplates the provision of a novel bowling score training apparatus having-means for presenting pinfall numbers for each successive frame of one or more games, and correct scores in a step by step sequence in order to teach a trainee or bowler practicing the art of scoring each aspect of scoring in conformity with the prescribed rules promulgated by the American Bowling Congress.

It is a further object of the invention to provide novel method of and mechanism for training a player in the art of keeping score in the game of bowling by providing means for presenting pinfall numbers and correct 'scores' and/ or spares With these and other objects not specifically mentioned in view, the invention consists in certain combinations and constructions which will be fully described hereinafter, and then set forth in the claims hereunto appended.

Referring to the drawings, the apparatus selected for purposes of illustration comprises a housing 2 of suitable design adapted to be positioned on a support such as a table or counter (not shown) or, if desired, it can be mounted on a stand (not shown). The apparatus comprises a suitable frame F including side plates 3 and 4, mounted on a base plate (not shown). Frame F is enclosed-within housing 2. As best shown in FIGURES l and 2 housing 2 is provided with a table portion 26 and an upwardly inclined portion U. A score pad 24 on which the trainee or bowler is learning to score or practicing to im-' prove his scoring skill is mounted in any known manner on table portion 26. Upwardly inclined portion U is provided with viewing windows through which the frame to frame pinfall of a game being scored and the correct score can be viewed and the latter compared with the score which the trainee has computed and entered in scoring pad 24.

The term player as used herein designates any individual; e.g., bowler, who is practicing the art of scoring, or a novice bowler or player or trainee who is learning to score the game of bowling.

As shown and described herein, the apparatus is designed for teaching scoring of the bowling game of ten pins. It will be appreciated, however, that the invention can also be adapted for use in teaching the scoring of other games of bowling such for example as a duck pin game in which three balls per frame are used.

The scoring trainer apparatus embodying the invention includes a number drum 6, a shutter drum 8, which coacts with number drum 6, and a score display and indexing mechanism designated generally 10.

Number drum Number drum 6 is keyed to shaft 16 rotatably mounted in bearings 18 in side frame plates 3, 4. The outer periphery of drum 6 is provided with circumferentially spaced rows 22 of pinfall indicia 20 for a plurality of complete games ranging from the simplest non-mark game to varied and complex pinfall games involving one or more strikes and spares which can occur during the many games of bowling, depending upon the skill of a bowler.

As shown in FIGURE 6, indicia 20 of each of the parallel rows 22 extend along the surface of drum 6. Each row consists of ten sets of pinfall indicia 20 representing each of the ten frame boxes of a conventional bowling score. The first nine sets of pinfall indicia 20 on drum 6 are limited to the pinfall for two balls. The tenth set of indicia may indicate pinfall for three balls, as for example when a strike is made on the first ball in the tenth frame (see game 2 on drum 6, FIGURE 6), or a spare is made on the second ball of the tenth frame.

If, according to information given in a row, a strike has been made, the second ball is indicated by a blank or space. However, the player enters an X in the proper score pad frame box. Similarly, if a spare is indicated the sum total of the pinfall is ten. However, the player enters the approved inclined line in the second box of the particular frame box corresponding to that of the frame being scored. The player scoring a game on score pad 24 on table portion 26 of housing 4, enters the appropriate mark in the proper small square or rectangle in the upper right hand corner of the frame box in which the complete set of ten pins is knocked down'by the first or second ball. Collars 28 fixed to shaft 16 secure drum 6 against lateral movement thereon.

In order to elfect the purposes of the invention, mechanism is provided for displaying successively the frame pinfall indicia on number wheel 6. That is, after a player has entered the pinfall results in the first frame box on pad 24, the device is operated in such manner that the pinfall for the second frame is next displayed, and so on until the game is finished and scored.

Shutter drum 8 is provided with a cylindrical masking portion 32 encircling number drum 6 mounted on end caps 34 having bearings 35 loosely rotatably mounted on reduced end portions of shaft 16. Collar 37 at one end of shaft 16 and gear 39 at the other end prevent lateral movement of drum 8. Portion 32 can be made of any suitable material or combination of materials. As shown herein cylindrical portion 32 preferably is formed of a suitable transparent material, such as glass, or plastic, having parts thereof opaqued to form a masking pattern 36. FIGURE 7 shows a development of portion 32 of drum 8, wherein masking pattern 36 comprises a series of ten steps of equal rise but increasing width in order to effect the display or make visible to the player through window 38 in housing 2 the successive frame by frame pinfall on number drum 6 in a selected game as the scoring thereof proceeds. Shutter drum 8, as illustrated herein, is provided with two masking patterns 36. If desired one or more could be provided, depending upon the size of number wheel 6 and matters of space.

Window 38 in housing 2 extends horizontally across portion U. It is located in adjacent spaced relation with cylindrical portion 32 of shutter drum 8 such that as shutter drum 8 is indexed the progressive display of indicia 20 of a selected row 22; i.e., the game being scored, is effected. Number drum 6 is provided with game identification indicia 40 described hereinafter, which can be seen through masking pattern 36 of cylindrical portion 32. Substitute for masking pattern 36 preferably is formed with circumferentially extending separating sections 39 which forms space 41 through which the number of a selected game being scored is displayed. This information advises the player that the game he is scoring conforms to the actual accurate score of the score display mechanism 14. As shown in FIGURES 1, 5 and 6, game 1 is being scored.

Score display mechanism ber wheel 6; i.e., 5 and 3, in the first frame box of score pad 24, he is afforded means for checking the accuracy of his efforts. This is done by referring to score display mechanism 14 through window 42. The construction and operation of the apparatus is such that the score of a frame should always be computed and entered in the appropriate frame box in pad 24 by the player before he operates the apparatus to effect the display through window 42 of the actual scole of the simulated game being scored. This window, which is suitably mounted or formed in the front wall of housing 2, allows the player to view the progressive display of the actual accurate game score of the game he is scoring after he computes and enters the score in successive frame boxes in pad 24 and operates the score display mechanism operating lever 60.

In the embodiment of the invention shown in FIG- URES 1, 4 and 5 score display and indexing mechanism. 10 comprises an endless web 44 on which is printed or otherwise applied a plurality of accurate game scores illustrative of games ranging from simple, relatively low scores to multi-mark high score games. The length of web 44 shown in FIGURE 5 illustrates the scores of one full low score and one high score part game. The number of complete accurately scored games contained on web 44 corresponds to the number of games contained on number drum 6. Game 1 on drum 6 is the same game as game 1 on web 44. Each scored game on web 44 comprises a plurality of frame by frame score units printed in longitudi-' game web 44, when the first frame pinfall on number drum 6 is made available to the trainee or player through window 38, a blank space a (1() position) is shown on web 44 through window 42. The player, after referring to the rules printed on pad 24, then enters the pinfall for the first frame; i.e., 5 and 3 in the proper spaces in the first frame box of score pad 24 and also enters the total 8 in that box. He then presses lever 60 which causes the movement of web 44 from 1-0 position to 1-1 position (see FIGURE 5), and the simultaneous one step movement of shutter drum 8 to expose additionally the second frame pinfall of this same game on number drum 6-. This operation gives the player the accurate comparison score indicated at b (l1 position of web 44) in FIGURE 5 of game 1, first frame, or 8, and also discloses to him, through window 38, the pinfall 8 and 2, or 10, for the second frame.

By reference to the scoring miles on score pad 24, the player knows that the pinfall for frame two, game 1, constitutes a spare and that he has a bonus ball; i.e., the pinfall results of the first ball of the next frame to add to the ten for a spare. Therefore, in the small upper right-hand boxes in the frame box for frame 2 he enters an 8 and an inclined line designating a spare. He then depresses lever 60 which advances web 44 to position 1-2 or c (FIGURE 5 to expose the accurate scoring for the second frame of this game and also by movement of shutter drum 8 the pinfall for the third frame of game-1 is also displayed to the player. In this case number drum 6 shows that pins were knocked down by the first ball in the third frame. It should be noted since a spare was made in the second frame the score was not immediately entered in the frame box for the second frame of this game because, in accordance with the rules of play the player is allowed the pinfall of the first ball of the next frame, i.e., the third frame, in computing the pinfall for his spare in the second frame. Since the pinfall shown on number wheel 6 for the first ball of the third frame of game 1 indicates a strike, upon reference to the rules of play on score pad 24, the trainee adds 10 to the total pinfall for the second frame, or a total of 20 to the score 8 in the first frame box, which gives him a total of 28 which he enters in the second frame box. To prepare for scoring the fourth frame of this game the lever 60 is pressed which makes visible the pinfall for the fourth frame of 6 and 1. At the same time, web 44 has been moved one step to show the accurate scoring for game 1third frame, or to position d which shows a total score of 28 through the second frame, with a strike yet to be scored. However, the player after resort to the rules printed on score pad 24, knows that since a strike is indicated in the third frame, the pinfall seven is to be added to the ten gained by the strike which, when added to 28, gives a total of 45 for the third frame. Also, since the fourth frame is a non-mark frame he adds 7 to the 45, which results in a total of 52 for the score of the fourth frame. When lever 60 is depressed to cause shutter drum 8 to disclose the pinfall of the fifth frame simultaneously therewith, row e, corresponding to game 1 fourth frame can be viewed through window 42. This allows the trainee or player to compare the score which he has entered in the fourth frame of score pad 24 with that displayed through window 42. If his score is the same as the score of 52 viewed through window 42 he knows that he has scored the game properly thus'far. In like manner, from frame to frame, web 44 is advanced through positions e-k until the final score of 110 is shown through window 42, which score should be the same as that which the player has himself entered in the tenth frame box of the game he has been scoring on score pad 24.

Indexing mechanism End caps 34 of shutter drum 8 are provided with sprocket portions 46 having teeth or lugs 48 which en- 6 i gage equidistantly spaced perforations 50 formed along both edges of web 44. When caps 34 are rotated both web 44 andshutter drum 8 are advanced. As best viewed in FIGURE 3, a ratchet 52 is attached, as by screws, to the left end cap 34. A pawl 54 pivotally mounted on pin 56, extending through an arcuate slot in side plate 3, is carried by arm 58 of operating lever 60 and engages the teeth of ratchet 52. Torsion spring 62 encircling pin 56 maintains pawl 54 in proper operative relationship with ratchet 52. Operating lever 60 which is pivotally mounted on bolt 64 in side plate 2 is provided with an operating arm extending outwardly from housing 2 such that player can engage and depress it as required in scoring a game. Spring 66 having one end attached to lever 60 and its other end secured to side plate 3 returns lever 60 to its initial or ready position. A conventional dashpot 68 secured at its ends to lever 60 and side plate 2 controls the rate of downward movement of lever 60 and thereby prevents malfunction and damage to the machine. Stops 70 and 72 mounted in side plate 2 determine the upper and lower limits of movement of lever 60.

Web 44 is supported in known manner on a plurality of support members such as rods 74 mounted in side plates 2 and 3. Upon rotation of caps 34, web 44 moves over these rods. Depression of operating lever 60 through a full stroke causes pawl 54 to turn ratchet 52 one step. This advances web 44 a given distance which exposes the correct score of a frame through window 42. Similarly shutter drum 8 is turned one posing an additional frame; i.e., the next frame pinfall on number drum 6 through window 38. This latter drum does not turn until a complete game has been scored by a player on score pad 24 and the corresponding complete accurate-1y scored game on web 44 has been displayed through window 42 to the player for comparison.

Gear 76 is attached to ratchet with two teeth 78, each 180 apart which coact with transfer gear 80 rotatably mounted on stud 82 in sideplate 2. Gear 80 also meshes with gear 39 carried by shaft 16. The positions of gear teeth 78 of gear 76 are such, relative to opposite teeth of ratchet 52, that when the end of a game is reached, one of the teeth 78 thereon moves in to mesh with transfer gear 80 which in turn rotates gear 39 to advance number drum 6 one step. 'In this manner the next game to be scored by a player on pad 24 is made available at window 38.

A block 84 attached to the inner face of side plate 2 carries two spring detents 86, 88. Detent 86 coacts with ratchet 52 to prevent undesired forward or rearward turning movement thereof. Detent 88 engages the teeth of gear 39 for similar purposes.

As stated above web 44 can be provided with a plurality of games ranging from low to very high scores. An important feature of the invention is that it makes it possible for a beginner as well as those who know how to score, to learn and/ or check their knowledge of the art of scoring under many varied scoring problems set up by the machine. It will be provided with games which are repetitive for two or more games or intermixed so as to drive home points of the problems posed. In accordance with the invention mechanism is also provided for adapting the apparatus in such manner that a player may select for scoring a game of any desired complexity.

Referring to FIGURE 1, it will be noted that there is a vertical complementary relationship between the frame box scores on web 44 and the number wheel 6. This arrangement has been found to be satisfactory in maintaining a visual vertical continuity relationship between the accurate computed score of web 44 and the pinfall per frame box indicated on number drum 6. It has also been found desirable to provide a score pad 24 of such size and design that a similar relationship exists between the frame boxes of a game to be scored by a trainee or a player. In FIGURE 1, the score pad is shown as prostep which results in ex 52. This gear is provided appreciated also that web 44 can be viding a single game to be scored. Obviously any desired number of lines or games could be provided thereon, as in conventional score sheets.

In the modified form of invention shown in FIGURE 8, the medium which supplies the accurate frame scores for selected games comprises web 100. Its length is suflicient to have printed or otherwise applied thereto a plurality of accurate complete game scores, as in the case of endless web 44. One end of web 100 is attached in known manner to flanged drum 102. loosely rotatably supported on shaft 104 fixedly supported in side frame plates (not shown) of housing 106 similar to housing 2 shown in FIGURES 1 and 4. The other end of web 100 is suitably attached to flanged drum 108 fixed to rotatable shaft 110 supported in the side frame plates which support shaft 104. Web 100 runs over support bars 112 similar to rods 74. Its edges are preferably provided with perforations (not shown) similar to those in web 44, which are engaged by pins 48 on shutter drum 8. The entire mechanism designated generally 116 including shutter drum 8, number drum 6 and their operating means are the same in construction and operation as that described hereinabove and shown in detail in FIGURES 1, 3 and 4. Sufiice it to say that when lever 60 is depressed shutter drum 8 advances one step to display additional pinfall results on number drum 6 and at the same time web 100 is advanced one step as in the case of web 44.

As shown in FIGURE 9 a relatively light load torsion spring 118 encircles shaft 104. One end of spring 118 is fixed to shaft 104; its other end is secured to drum 102. Shaft 16 supports sprocket 103 on which runs chain 122 which drive sprocket 124 on shaft 110. Thus, when lever 60 is depressed web 100 is unwound from drum 102 and wound on drum 108.

As the result of the repeated intermittent movement of web 100 energy is stored in spring 118. Referring to FIGURE 8, when shaft 16 is turned in a clockwise direction as viewed in FIGURE 8, drum 102 is turned in a counterclockwise direction to effect the rewinding of web 100 thereon. Detents 86, 88 prevent rearward or upward movement (as viewed in FIGURE 8) of web 100 by spring 118.

Shaft 16 in the forms of the invention illustrated herein can be turned, as desired, to effect any desired movement of shutter drum 8, web 44 or 100 and number drum 6 to allow a player to repeat the scoring of the same game, or to allow him to select a game of more or less complexity to challenge his scoring ability.

FIGURE 3 discloses one way for effecting this result. Gear 126 carried by shutter drum 8, meshes with gear 128 on sleeve shaft 130 suitably rotatably supported in bearing 132 in side frame plate 4. Shaft portion 134 of crank 136 which extends through side wall of housing 2 is provided with a cross pin 138. When the player grasps handle 140 of crank 136 and moves it to the left against the pressure of spring 142 encircling sleeve shaft 130 and bearing against collar 131 on shaft portion 134, cross pin 138 is seated in slot 144 in sleeve shaft 130. Upon turning crank 136 to or from him to effect the rotation of shutter drum 8, number drum 6 and the movement of web 44 (100) as required, the player can make a selection of a game which he wishes to score.

Pawl 54 and detents 86 and 88 are so designed that they do not prevent the manual turning of shutter drum 8 and number drum 6.

The invention also contemplates the progressive display on number drum 6 of the pinfall for each individual ball for each frame as the frame to frame scoring of a game proceeds; Referring to FIGURE 11, it will be noted that gear 146 which corresponds in function to gear 76 described hereinabove is provided with a single tooth 148. The shutter drum (not shown) which operates in the same manner as shutter drum 8 is provided with a single masking pattern 150. (See FIGURE 10.) This pattern is so designed that each line-a, b, c, etc. thereof will display the pinfall results on number drum 6 for one ball only for each movement of the shutter drum. The number of masking patterns on shutter drum 152 can vary according to its diameter and that of number drum 6.

As illustrated in FIGURE 12, web 154 which corresponds to webs 44 and is provided with accurate score indicia which conforms to the ball by ball and frame by frame score entered by the player in score pad 24. Except for the modifications described the construction and operation of this modified form of the invention is the same as in the modification shown in FIGURES 1-7 and 8 and 9. Detailed description thereof is omitted in the interest of brevity.

Webs 44, 100 and 154 can be made of any suitable material which has good strength, and the capacity to permit printing or other delineation thereon of scores such as shown in FIGURES 5 and 12. Plastics, paper, woven web materials and combinations thereof can be used. We have found that a web made from a plastic known as Mylar, made and sold by the Du Pont Company, Wilmington, Del., gives satisfactory results.
