BOWLING ALLEY SCORING AND TIMING PROJECTOR DEVICE Filed Dec. 23, 1954 5 Sheets-Sheet 5 INVENTOR ROBERT L. HOLLOWAY ATTONEY United States Patent BOWLING ALLEY SCORING AND TIMING PROJECTOR DEVICE Robert L. Holloway, Snyder, N. Y., assignor to American Machine & Foundry Company, a corporation of New Jersey Application December 23, 1954, Serial No. 477 ,356
Claims. (Cl. 8824) This invention relates to a bowling score device, and more particularly to a bowling score projecting device provided with means for informing one or more players, and/ or spectators and alley managers of the progress each player is making during the course of playing the game, and to relate this progress to a norm for such progress.
The present invention is operative to project bowling scores written or printed by a score keeper on a bowling score card or sheet mounted on a stand at the head end of an alley for projection onto a screen located preferably above the alley and some distance from the playing position where it is visible to the players, spectators, manager and the score keeper. It is well known that from time to time during the course of playing the game, some of the players may be inattentive to the play, and the game drags because they are not ready to bowl on time. When this occurs, time is lost which could otherwise be of productive value to a proprietor. Accordingly the present invention covers the provision of means which visibly informs all players when the game starts and the progress being made during the course of play, with specific reference to the elapse of time. As the result of my invention, players obtain greater enjoyment of the game, and higher scores. Where pin boys are used for setting pins, they do their jobs in a more efficient manner. Furthermore, in league play, games start and finish according to schedule, alleys can be kept cleaner because of availability of time for cleaning between matches played by succeeding teams, and proprietors are more satisfied because of the efficient use of time and the resulting greater income.
In a preferred form of the invention, there is provided an optical projecting device which projects the score from a score pad onto a screen located above and down the alley. Also associated with the optical projecting device is a moving transparency or means for indicating the passage of time on the projected representation of the score sheet. This may be done in any suitable manner, as by a moving light beam of a selected size and shape or shadow which is adapted to travel from left to right until finally when the tenth frame shall have been played, the projection of the time indicator moves to the extreme right of the projected score pad.
in normal league play when there are two sets of five players each playing on adjoining alleys, it is customary for a game to last about forty minutes. Accordingly in accordance with the invention, there is provided a moving projected time indicator which travels at such a rate that in moving from the extreme left to the extreme right of the projected score pad, forty minutes, more or less, lapse. If less than five players play, the timing period can be adjusted so that, depending upon the number of players playing the game, the projected time indicator moves from the extreme left to the extreme right of the score pad in the desired amount of time.
Where used herein, the term projected time indicator is intended to mean a suitable shadow cast by an opaque element forming a part of the time indicating system, or a projected light beam of suitable size and shape which is Cir a! projected and moved during the course of play of a game progressively and continuously across the projected representation of a score sheet or card.
-t is an object of the invention to provide an improved bowling score projecting device having means for apprizing players, spectators and manager of the progress of the It is a further object of the invention to provide a novel score projecting device having associated therewith means for informing players and spectators of the progress the players are making during the course of play of the game, and also making it apparent that undue delay is being caused by one or more players if the time indicating means travels beyond the column in which figures are being entered.
It i a further object of the invention to provide an improved scoring device having associated therewith signalling means for informing players that they are delaying the game unduly.
The invention also contemplates the provision of automatic means for indicating the progress of the bowling game, and for adjusting the movement of the indicating means in accordance with the number of players playing, said means being further adjustable to vary the time allowed for any given number of players.
With these and other object not specifically mentioned in view, the invention consists in certain combinations and constructions which will be described fully hereinafter, and then set forth in the claims hereunto appended.
In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same or like parts:
Fig. l is an isometric view illustrating one embodiment of the invention;
Fig. 2 is a rear view of the score projecting device made in accordance with the invention;
Fig. 3 is an isometric view showing the invention and illustrating somewhat in detail the light beam scanning device and the optical system associated therewith;
Fig. 3a is a perspective view showing a modified form of time indicating means; and
Fig. 4 is a side elevation showing a modified form of the invention.
Referring to the drawings, and especially Figs. 1 and 2, it will be seen that the score projecting device, and the timing mechanism associated therewith are mounted in a suitable casing, designated 10. Casing 10 is supported on uprights or standards 12, suitably attached to pad supporting table 16. Score pad supporting table 16 is mounted on a standard 18 having an enlarged base 20. Score pad 22 is held positioned on table 16 by a suitable clamp bracket 24 of conventional design.
In the embodiment illustrated in Figures 1, 2 and 3, mounted within casing 10 is a suitable optical system which is provided with conventional lenses and mirrors for scanning the score pad 22. The scanning range of the scanner lens 23 of the optical system is indicated in broken lines 28 in Figs. 1 and 2. Any suitable conventional scanning-projecting device may be used. For example, a Taylor spot light opaque projector may be used.
It is essential that in the scanning and projecting device used, the light, lens and mirror system be capable of not only scanning the score pad as indicated in Fig. l, but also being able to project the entire indicia of the score pad 22 onto a screen 30 suitably mounted down the alley, or at a point somewhere intermediate between the end of the bowling alley and the players position. Screen 30 is so mounted that it is above the line of play of the alley and therefore offers no obstruction or abstraction to a bowlers complete enjoyment of the game.
As shown in Fig. 2, light rays 15 are projected downwardly from light sources 14 in casing 16 onto score pad. 22. Reflected light from score pad 22 is collected and projected by means of a suitable optical system including lens 23, objective lens 36, and mirror 26, onto screen 36 as indicated in broken lines 23 and 32, whereby the entire indicia on the score pad 22 is made visible to those who are observing screen 36 from the players end of the alley. It will be seen that as each individual bowlers score is noted on score pad 22, it will be visible on screen 30 by means of this projecting system described hereinabove.
In playing the game of bowling, and especially in league play where large numbers of people congregate and each team is composed of five players, considerable time may be lost with a commensurate loss in income to the bowling alley proprietor, unless each player is aware of the fact that he should play in more or less of a timed operation. Thus in order to prevent undue delay caused by capriciousness or other acts on the part of bowlers, and to let all members of respective teams or all players become aware of the passing of time and the desire to maintain a progressive play which actually contributes to the enjoyment of the game since it has the etfect of increasing the rhythm of play, I have provided means for indicating the passage of time which forms an important part of this invention.
One form of the invention embodying the indication of the passage of time is disclosed in Fig. 3. In this figure, the casing has been removed to disclose an endless flexible member 40 which is provided with rows of perforations 42 at the top and bottom, which perforations are adapted to be engaged progressively by means of teeth 44 on sprockets 46.
In the illustrated embodiment, endless member or belt 40 is disclosed as having a substantially quadrilateral path of movement. It will be understood that it could also take some other path, such for instance as elliptical or circular. Referring more especially to endless member or belt 40, it will be seen that it may consist of a top strap 48 and a bottom strap 50 in which perforations 42 are provided. Attached to the straps 48 and 59 are lengths 52 and 54 of a flexible material, such for example as plastic. This plastic may be cellulose acetate, a polyethylene film, or any other suitable plastic which is flexible and which will not bend or warp because of the presenceof some heat in the enclosing container 16. A line of demarkation 56 separates transparent tinted areas of flexible members 52 and 54, one being, say red, and the other, green. Any other color combination could be used. Because of the difference in the colors of the two strips or lengths 52 and 54, it will be seen that where they are joined together, there will be a. line of demarkation projected on the screen 36. In a case where an elongated opaque member connects strips 52 and 54, a line of demarkation 56 will be an opaque projected line.
The indicia projected through lens 36 onto screen 36 through belt 40 will appear tinted on screen 36 in accordance with the positioning of line 56. The line 56 positioning is controlled by tooth sprockets 46 which in turn are positioned by a suitable standard timing motor, such as a conventional type of adjustable timing motor, or other suitable device. It will be apparent that suitable adjustment of timing motor 62 will cause the color line of demarkation 56 to progress across the projected score pad at the anticipated proper rate of progress of the game, thus suitably reminding the bowler of deviation from such rate. Timing motors are also available, which automatically reset to zero after a desired lapse of time. 7 This type of timing motor therefore could be used to reset automatically the time indication for the succeeding game.
Referring to Fig. 3a, an equally satisfactory time indication may be achieved by employing a belt assembly designated 1% which may or may not be tinted, or by eliminating the flexible transparent material between members 57 which are positioned vertically, as was line 56 in Figure 3, and equally spaced along the length of straps 48 and 5% When suitably adjusted, the speed of motor 62 will cause the plurality of equally spaced vertical opaque members 57 to successively traverse the optical view of lens 36, thus casting a shadow on screen 36 as a passage of time indication. Here, color is not involved and no reset is required for the succeeding game, because the spacing between members 57 is so arranged that the projected image of one member 57 moves on the projected image of the score sheet on screen 3% The image of the next member 57 is located in proper position on screen 36 for the next game.
In the embodiments shown in Figures 1 to 3 and 4, the reset position of the belt 49 is so determined that the projected image of the line of demarcation 56 is located to the left of the first scoring column 31 of the projected score sheet 22 on screen 36 at the beginning of a bowling game. At the end of the game belt 4% has moved to such an extent that line 56 is located adjacent the right edge of the projected image of score pad 22 or to the right of the last column containing the total scores of the players. When line 56 reaches this latter position, the travel of belt 44 is interrupted by the stoppage of motor 62.
Referring to Fig. 3, it will be seen that the output drive shaft 64 of motor 62 is connected by a cut coupling 66 of conventional design. Cut coupling is normally maintained in operative relationship by means of a spring 70 encircling shaft 68 which mounts two of the sprockets 46, these being the driving sprockets. The three other sets of sprockets 46 are mounted on idler shafts suitably supported in the base 11 of casing 10. As indicated in Fig. 2, the top end of shaft 68 is provided with a knob 72 attached thereto in order that at the end of a game, the score keeper may pull up on shaft 68 which is slidably splined to sprockets 46 so that on turning the shaft 68 in the direction of arrow B, belt member 40 may be moved to the left, as in Fig. 3, and reset at its zero position l, as viewed in Fig. 1. Power for motor 62 is fun nished by any suitable exterior source of power designated generally 39. By means of adjustment provisions in the Haydon type timing devices and/or rheostats or record play type speed changers, the speed of the time indicating device and the period of operation can be varied in order to conform with the number of players rolling on a particular bowling alley. Thus if one player is playing the game, the point of knob 84 will be turned to position indicated 1. In this case, the transit of the line of demarkation 56 from left to right, as viewed in Fig. 1, will be approximately 8 minutes, which is the normal rolling time for a single player. In the same manner by ad justing the position of knob 84 to positions 2, 3, 4 and 5, the increased periods of time are afforded for the transit of the image 60 of time indicator member 56 across screen 30.
It will be noted that in Fig. 3,- a switch 86 is indicated for closing the circuit through motor 62 in order to start the operation or the movement of belt member 40. If desired, the leads of the motor 62 may be connected to a control system (not shown) of a bowling pin spotting machine, such as that indicated in Broekhuysen Patent 2,559,274, so that when a ball or the first ball of a game arrives in the pit of a bowling alley (not shown), the circuit through motor 62 is closed and belt member 40 begins to operate. Here again, as in the case described directly above where motor 62 is started manually, the position of knob 84 is set in accordance with the number of players rolling the game. Motor 62 continues in operation until the end of the predetermined period, when it stops, depending upon the number of players.
As a visual means for apprizing a player of the progress of his game, or for informing a team of the progress they are making, the speed of movement of belt 40 is so set that the average time of rolling a game or frame is taken into consideration. If there is an undue delay in the playing of the game, the shadow line of time indication will move ahead or to the right of the filled in score columns on score screen 30, or the line of color demarcation will be similarly positioned, thus indicating to the players that they are not keeping up with the game. On the other hand, if the shadow line of time indication or the line of color demarcation shows to the left of the filled in score columns, it will be an indication that the play of the game is progressing in accordance with, or less than, average timing and that the game will be finished on. time and that all parties will be satisfied with the progress of playing the game.
The score projecting device shown in the modification illustrated in Fig. 4 may be similar in construction and operation to that disclosed in Coker Patent 2,381,269. The objective lens housing, however, is essentially the same as that disclosed in Figs. 1 to 3, inclusive, in that it is provided with a time lapse indicating mechanism designated generally 152 which may be similar in construction and operation to that disclosed in Figs. 1, 2, 3 and 3a. As indicated at 172, there is provided a resetting device which functions in the same manner as elements 72, described hereinabove.
In the modified form illustrated in Fig. 4, there is provided a stand designated generally 110 recessed at 111 to accommodate the feet of the score keeper when he is seated in score keeping position. The top of stand 1!) is formed with a table 112 provided with a translucent panel 114 fitted into a suitable opening formed in table 112. Panel 114 provides a suitable writing surface on which a score card of sheet 115 bearing the conventional bowling score indicia, may be placed and held by clips 117, as indicated in Fig. 4, so that the projector which is of a suitable conventional type, may project the score by means of objective lens 136 onto screen 30.
Suitably mounted within stand 110 is a light socket bracket 118 which provides a support for an electric bulb 12 .5 to furnish the source of light. A concave reflector 122 is positioned directly below bulb 120, reflector 122 being suitably supported on a bracket 124 attached to stand 110. Any suitable conventional system of optics may be used in the projecting device. A pair of lenses 121, 121, comprising a condensor system, is secured in frames 126 suitably secured to the interior of stand 110. It will be seen that light from bulb 120 passing through lenses 121 will project an image of the score card into housing 128 suitably mounted on standards 129 attached to table 112. The rays of light passing through score card 115 are received on a mirror 130, and directed thereby through objective lens 136 onto a screen, such as screen 38 mounted above the alley, shown in Fig. 1. As stated hereinabove, located within housing 128 is a time lapse indicating mechanism 152 which may be the same as that disclosed in Figs. 1, 2, 3 and 3a. The operation of this structure, shown in Fig. 4, is exactly the same as that disclosed in the form of invention illustrated in Figs. 1 to 3, and 3a.
