- Keister [4 1 Jan. 25, 1972 [54] PATTERN-MATQHING PUZZLE [72] Inventor: William Keister, 66 Baltusrol Way, Short [52] US. Cl ..273/156 1,218,014 3/1917 Swartwood ..273/153 R Primary Examiner-Anton O. Oechsle Att0rney.lames Warren Falk 57 ABSTRACT A pattern matching game is disclosed in which a slide-carrying teeter bars has to be removed from a frame by selectively pivoting individual ones of the teeter bars through a gate element in one rail of the frame.
- a series of pattern bars carried by a support or rack adjacent the frame member prevent opening of the gate element unless the position of the teeter bar adjacent each pattern bar matches the pattern bars.
- the pattern bars may be removed and rearranged in different patterns creating a number of different puzzles, each requiring a different series of moves for its solution.
- This invention relates to a puule game and more particularly to a pattern-matching puzzle.
- Triple rings that can be assembled, in a unique way, into a single ring are of this type. So are wooden objects, such as balls or squares, made up of interlocking parts that must be assembled in a certain order.
- a plurality of teeter bars are provided together with a lesser plurality of pattern bars.
- the teeter bars are mounted on a slide positioned in a bed or frame between two side rails.
- the higher side rail has two characteristics. First, there is a groove extending along the length of the bed so that oneend of the teeter bars can be positioned in it; the groove does not extend to the end of the bed, however, so that the slide cannot move off the bed unless all of the teeter bars are positioned so that their one ends rest on top of that higher side rail.
- the second characteristicof the side rail is that it has an opening substantially midway in the side rail, the opening being as wide as a teeter bar so as to provide a path through which the teeter bar may be pivotally moved to shift the position of its one end between the groove and the top of the side rail or between the top of the side rail and the groove.
- a gate element is positioned in this opening. In its normal position it appears merely as a part of the side rail and thus forming a part of the frame. Accordingly a teeter bar end can pass along its top or along the rail groove at the gate element.
- the gate element is physically connected to a spring loaded support or rack positioned adjacent the lower side rail. The player of the game by pressing the support member against this slight spring bias can move the support member up to the lower side rail. This simultaneously pushes the gate element out of the opening in the other rail, to allow a change in the position of a teeter bar.
- the support member carries a number of pattern bars. These are advantageously removably supported, as by a pin, so that their pattern can be altered at will, thereby varying the solution to the puzzle.
- the pattern bars are shaped so that each presents one of two patterns to the teeter bars. Either a pattern bar requires that the teeter bar directly adjacent it be resting on the higher side rail, in which case the pattern bar will pass over its other end, or the pattern bar requires that the teeter bar adjacent it be in the groove, in which case the pattern bar will pass under the other end of the teeter bar.
- teeter bars there are more teeter bars than pattern bars.
- the slide In the initial position of the puzzle, the slide is at the end of the base away from the stop or closed end of the groove. All of the teeter bars have their one ends below the upper surface of the higher side rail and in the groove.
- the object of the puzzle is to manipulate the slide and the gate element to allow the slide to be removed from the other end of the base. Since the groove at that end is blocked by the stop, this requires that all of the teeter bars be moved so that their one ends rest on top of the higher side rail.
- a teeter bar can only be pivoted when it is at the gate and the gate element may be moved. This in turn can only occur if the teeter bars adjacent the pattern bars, which may mean up to four teeter bars, match their positions against the patterns of the pattern bars. If one or more of the pattern bars in the test spaces do not match the teeter bars, the pattern bars strike the teeter bars and the gate cannot be opened. What is required therefore is a series of moves of the slide backwards and forwards, with teeter bars being pivoted at the gate position so that those teeter bars (from zero to four) at the test positions adjacent pattern bars match the patterns of the pattern bars.
- each of the possible combinations of patterns represents a different puzzle requiring a different sequence of movements of the teeter bars for its solutions and, with four pattern bars, there are sixteen different puzzles.
- the simplest pattern (all pattern bars up) is trivial and requires only the eight moves needed to pivot the eight teeter bars individually through the gate position. The longest of the 16 puzzles however takes moves. Some patterns requiring an intermediate number of moves are actually more difficult, however, since the sequence of moves is more complex.

- FIG. 5 is a sectional view of the frame member, gate element, and pattern bars taken along the line 5-5 of FIG. 3.
- the puzzle comprises a frame or base member defining a bed portion 11, a higher side rail 12, and a lower side rail 13.
- the two side rails extend slightly over the bed portion 11 so as to define tracks 15 in which a slide 18 can be positioned.
- the higher side rail 12 has a sloping upper surface 19 on which teeter bars 21 can rest their one end and also a groove 20 extending almost its entire length. The ends of the teeter bars 21 can also rest in the groove 20. However a stop element 23 is positioned at one end of the groove 20. This stop elem'ent may be physically a portion of the rail 19, as depicted, or may be merely a pin extending in the groove 20. Its purpose, as will be apparent from the subsequent description, is to prevent the slide 18 from being removed from the frame at that end of the frame whenever any one teeter bar 21 has its end positioned in the groove 20.
- the higher rail 19 also has an opening in its upper surface, as best seen in FIG. 3. Normally however this opening is closed by a gate element 26 is formed so as to -appear merely as a portion of the rail 19, as seen in FIG. 1.
- the gate element 26 is carried by a gate support 27 which is connected as by rods 28 to a pivot bar support member 30, discussed further below.
- the slide 18 has two end mounts 31 between which the teeter bars 21 are pivotally mounted, as on a pin or rod 32.
- any one of the teeter bars 21 may be pivoted between a position wherein its one end is in the groove 20, as shown in FIG. 1, and a position wherein the one end rests on top of the higher side rail 19.
- the gate element 26 is supported by a gate support 27 physically connected, as by the rods 28, to a pattern bar support member 30.
- Member supports a plurality of pattern bars 34, 35, 36, and 37 In accordance with my invention these bars may be readily removed and their positions changed; to that end they are supported by a removable pin 39 extending through the support 30. Further they are shaped so as to have a sloping surface 40.
- the support 30 will be blocked from moving whenever any teeter bar 21 is positioned opposite the pattern bar 36.
- the teeter bar at the pattern bar 36 must have been pivoted so that its one end rests on the upper surface 19 of the side rail 12, in which case the other end of the teeter bar will pass under the sloping surface 40 of the pattern bar 36.
- a spring 42 normally biases the support 30 away from the side rail 13.
- the slide 18 is held from removal out the open end of the frame 10 by a spring loaded pawl located in the bed 11 and cooperating with a slot 46 in the bottom of the slide 11 so that the slide 18 can only be removed from the closed end of the frame, that is, the end where the groove 20 is blocked by the stop member 23.
- the pattern bars are first set into one of the sixteen possible test patterns, depending on the number of pattern bars having their sloping surfaces 40 up or down.
- One possible combination of the pattern bars is depicted in FIG. 1, though this is only one of the sixteen possible puzzles for this embodiment.
- the slide 18 is slid onto the bed 11 with all the teeter bars 21 having their one ends in the groove 20, as depicted in FIG. 1. This is the initial position of the puzzle.
- the object of the puule is to manipulate the slide and the gate 26 so that all of the teeter bars 21 are placed above the rail 12 with their one ends on the surface 19, in which position the slide 18 may then be removed from the other end of the frame or base 10.
- the gate is connected by the cross members or rods 28 through holes in the bottom of the base 10 to the support or rack 30 carrying the four pattern bars 34-37.
- the pattern bars may be considered as appearing in four test locations at each of which locations it is possible to test the position of a teeter bar.
- the first pattern bar 37 defines a test position directly adjacent to the gate position, that is, when a teeter bar 21 is at the gate 26, the immediately preceding teeter bar is being tested by the pattern bar 37.
- the last pattern bar 34 is positioned directly next to the stop element 23 so that four teeter bar test positions are defined between the stop element 23 and the gate element 26.
- a teeter bar 21 is pivoted so as to have its one end in the groove 20, then it will bear against the stop element 23 and be tested by the pattern bar 34. At the same time the fourth succeeding teeter bar will be at the gate element 26 and can be pivoted through the opening 25.
- the gate element 26 is normally held closed by the spring 42, which also normally holds the pattern bars clear of the teeter bars so that the slide may move to and fro on the base 10, being limited in its motion by the stop member 23 and the pawl 45.
- a player would normally hold the base in his left hand with his thumb against the support or rack 30 while with his right hand he moves the slide 18. If the teeter bars in the four test locations match the setting of the corresponding pattern bars, the motion of the support under this thumb pressure can continue, thereby allowing the gate to open.
- table I A further characteristic of the puzzle in accordance with my invention can be noted in table I.
- a move of position in a teeter bar is only possible at the gate element position 25. Accordingly the teeter bar positions indicated for each move differ from the preceding and succeeding moves by only one teeter bar and in each case by the position of the teeter bar at the gate position 25. It is also apparent from the table how the slide must be moved both forward and backward to position the desired teeter bar at that gate position.

By WALL/AM lfE/STER ATTORNEY PATTERN-MATCHING PUZZLE BACKGROUND OF THE INVENTION This invention relates to a puule game and more particularly to a pattern-matching puzzle.
For centuries people have amused, and sometimes frustrated, themselves by devising puzzles. Many of these required only imagination or at best paper, pencil, and a logical or mathematical turn of mind. Cannibals and missionaries have been crossing rivers for generations; engines of trains have been reversing their directions on a siding for decades. Whole books of such puzzles are available.
Other puzzles require manipulation of physical objects, sometimes witha certain amount of dexterity but usually only with an appreciation of the underlying mathematical principles. Triple rings that can be assembled, in a unique way, into a single ring are of this type. So are wooden objects, such as balls or squares, made up of interlocking parts that must be assembled in a certain order.
One drawback of these puzzles is that they represent only a single puzzle each and thus only a single solution. Once the puzzle is made, its interrelations are set and cannot be changed. Having once accomplished the puzzle, the owner gets little satisfaction out of repeating the solution himself, though he may get considerable satisfaction out of observing others being unable to find the solution.
It is accordingly an object of this invention to provide a puzzle whose key interrelationships can be varied, therebyaffording the user a variety of different solutions.
It is another object of this invention to provide a patternmatching puzzle in which various elements must conform to set patterns as the puzzle is solved. More specifically it is an object of certain embodiments of this invention to provide such a puzzle in which the patterns can be varied between solutions.
SUMMARY OF THE INVENTION These and other objects of this invention are attained in one specific illustrative embodiment in which a plurality of teeter bars are provided together with a lesser plurality of pattern bars. The teeter bars are mounted on a slide positioned in a bed or frame between two side rails. The higher side rail has two characteristics. First, there is a groove extending along the length of the bed so that oneend of the teeter bars can be positioned in it; the groove does not extend to the end of the bed, however, so that the slide cannot move off the bed unless all of the teeter bars are positioned so that their one ends rest on top of that higher side rail. The second characteristicof the side rail is that it has an opening substantially midway in the side rail, the opening being as wide as a teeter bar so as to provide a path through which the teeter bar may be pivotally moved to shift the position of its one end between the groove and the top of the side rail or between the top of the side rail and the groove.
A gate element, however, is positioned in this opening. In its normal position it appears merely as a part of the side rail and thus forming a part of the frame. Accordingly a teeter bar end can pass along its top or along the rail groove at the gate element. The gate element is physically connected to a spring loaded support or rack positioned adjacent the lower side rail. The player of the game by pressing the support member against this slight spring bias can move the support member up to the lower side rail. This simultaneously pushes the gate element out of the opening in the other rail, to allow a change in the position of a teeter bar.
There is, of course, a catch to this simple operation. The support member carries a number of pattern bars. These are advantageously removably supported, as by a pin, so that their pattern can be altered at will, thereby varying the solution to the puzzle. The pattern bars are shaped so that each presents one of two patterns to the teeter bars. Either a pattern bar requires that the teeter bar directly adjacent it be resting on the higher side rail, in which case the pattern bar will pass over its other end, or the pattern bar requires that the teeter bar adjacent it be in the groove, in which case the pattern bar will pass under the other end of the teeter bar. If a teeter bar adjacent a pattern bar does not conform to the pattern of that pattern bar, the support member is blocked and cannot move adjacent the lower side rail. More importantly, when this happens the gate element cannot move out of the opening to allow a change in position of the teeter bar which is adjacent the gate element at that moment.
Advantageously there are more teeter bars than pattern bars. In the embodiment described herein there are eight teeter bars and four pattern bars. Since each pattern bar may present one of two patterns, these four pattern bars represent 16 different game solutions. The four pattern bars therefore appear at test locations for up to four teeter bars that may be located between the gate and the stop in the groove.
In the initial position of the puzzle, the slide is at the end of the base away from the stop or closed end of the groove. All of the teeter bars have their one ends below the upper surface of the higher side rail and in the groove. The object of the puzzle is to manipulate the slide and the gate element to allow the slide to be removed from the other end of the base. Since the groove at that end is blocked by the stop, this requires that all of the teeter bars be moved so that their one ends rest on top of the higher side rail.
As noted above, a teeter bar can only be pivoted when it is at the gate and the gate element may be moved. This in turn can only occur if the teeter bars adjacent the pattern bars, which may mean up to four teeter bars, match their positions against the patterns of the pattern bars. If one or more of the pattern bars in the test spaces do not match the teeter bars, the pattern bars strike the teeter bars and the gate cannot be opened. What is required therefore is a series of moves of the slide backwards and forwards, with teeter bars being pivoted at the gate position so that those teeter bars (from zero to four) at the test positions adjacent pattern bars match the patterns of the pattern bars.
As noted above, each of the possible combinations of patterns represents a different puzzle requiring a different sequence of movements of the teeter bars for its solutions and, with four pattern bars, there are sixteen different puzzles. The simplest pattern (all pattern bars up) is trivial and requires only the eight moves needed to pivot the eight teeter bars individually through the gate position. The longest of the 16 puzzles however takes moves. Some patterns requiring an intermediate number of moves are actually more difficult, however, since the sequence of moves is more complex.
DESCRIPTION OF THE DRAWING FIG. I is a perspective view of one specific illustrative embodiment of my invention;
FIG. 2 is an end view of the embodiment of FIG. I;
FIG. 3 is a plan view of the frame member, gate element, and pattern bars of the embodiment of FIG. 1, the slide and teeter bars not being in position;
FIG. 4 is a perspective view of two of the pattern bars, and
FIG. 5 is a sectional view of the frame member, gate element, and pattern bars taken along the line 5-5 of FIG. 3.
DETAILED DESCRIPTION Turning now to the drawing, there is depicted one specific illustrative embodiment of my invention of a pattern matching puzzle. As seen in FIG. 1, the puzzle comprises a frame or base member defining a bed portion 11, a higher side rail 12, and a lower side rail 13. The two side rails extend slightly over the bed portion 11 so as to define tracks 15 in which a slide 18 can be positioned.
The higher side rail 12 has a sloping upper surface 19 on which teeter bars 21 can rest their one end and also a groove 20 extending almost its entire length. The ends of the teeter bars 21 can also rest in the groove 20. However a stop element 23 is positioned at one end of the groove 20. This stop elem'ent may be physically a portion of the rail 19, as depicted, or may be merely a pin extending in the groove 20. Its purpose, as will be apparent from the subsequent description, is to prevent the slide 18 from being removed from the frame at that end of the frame whenever any one teeter bar 21 has its end positioned in the groove 20.
The higher rail 19 also has an opening in its upper surface, as best seen in FIG. 3. Normally however this opening is closed by a gate element 26 is formed so as to -appear merely as a portion of the rail 19, as seen in FIG. 1. The gate element 26 is carried by a gate support 27 which is connected as by rods 28 to a pivot bar support member 30, discussed further below.
The slide 18 has two end mounts 31 between which the teeter bars 21 are pivotally mounted, as on a pin or rod 32. By removing the gate element 26 from the opening 25 any one of the teeter bars 21 may be pivoted between a position wherein its one end is in the groove 20, as shown in FIG. 1, and a position wherein the one end rests on top of the higher side rail 19.
As noted above, however, the gate element 26 is supported by a gate support 27 physically connected, as by the rods 28, to a pattern bar support member 30. Member supports a plurality of pattern bars 34, 35, 36, and 37 In accordance with my invention these bars may be readily removed and their positions changed; to that end they are supported by a removable pin 39 extending through the support 30. Further they are shaped so as to have a sloping surface 40.
When a pattern bar is mounted by pin 39 on the support 30 so that the sloping surface is up, then that pattern bar will extend under a teeter bar 21 whose one end rests in the groove 20, when the pattern bar support 30 and the pattern bars are pressed towards the lower side rail 13. Thus, as seen in FIG. 1, a teeter bar 21 will allow pattern bar 37 to slide underneath it. On the other hand if a pattern bar hasits sloped surface 40 down, as pattern bar 36, then that pattern bar will hit against the end of a teeter bar 21 having its one end in the groove 20 thereby preventing the motion of the support 30 to abut against the lower side rail 13. Thus when the teeter bars are positioned as depicted in FIG. 1, the support 30 will be blocked from moving whenever any teeter bar 21 is positioned opposite the pattern bar 36. In order to allow the support 30 to move, the teeter bar at the pattern bar 36 must have been pivoted so that its one end rests on the upper surface 19 of the side rail 12, in which case the other end of the teeter bar will pass under the sloping surface 40 of the pattern bar 36.
The reason that movement of the support 30 is of such importance is because, as noted above, the gate element 26 is physically connected to the support. Thus when it is desired to open the gate element 26 to allow a teeter bar 21 to pivot either from the rail surface 19 to the groove 20 or vice versa through the opening 25, the support 30 must be moved against the side rail 13. A spring 42, best seen in FIGS. 2 and 5, normally biases the support 30 away from the side rail 13.
The slide 18 is held from removal out the open end of the frame 10 by a spring loaded pawl located in the bed 11 and cooperating with a slot 46 in the bottom of the slide 11 so that the slide 18 can only be removed from the closed end of the frame, that is, the end where the groove 20 is blocked by the stop member 23.
When it is desired to play the game, that is to solve one of the possible matching puzzles, the pattern bars are first set into one of the sixteen possible test patterns, depending on the number of pattern bars having their sloping surfaces 40 up or down. One possible combination of the pattern bars is depicted in FIG. 1, though this is only one of the sixteen possible puzzles for this embodiment.
The slide 18 is slid onto the bed 11 with all the teeter bars 21 having their one ends in the groove 20, as depicted in FIG. 1. This is the initial position of the puzzle. The object of the puule is to manipulate the slide and the gate 26 so that all of the teeter bars 21 are placed above the rail 12 with their one ends on the surface 19, in which position the slide 18 may then be removed from the other end of the frame or base 10.
As noted above, the gate is connected by the cross members or rods 28 through holes in the bottom of the base 10 to the support or rack 30 carrying the four pattern bars 34-37. The pattern bars may be considered as appearing in four test locations at each of which locations it is possible to test the position of a teeter bar. The first pattern bar 37 defines a test position directly adjacent to the gate position, that is, when a teeter bar 21 is at the gate 26, the immediately preceding teeter bar is being tested by the pattern bar 37. The last pattern bar 34 is positioned directly next to the stop element 23 so that four teeter bar test positions are defined between the stop element 23 and the gate element 26. Accordingly, if a teeter bar 21 is pivoted so as to have its one end in the groove 20, then it will bear against the stop element 23 and be tested by the pattern bar 34. At the same time the fourth succeeding teeter bar will be at the gate element 26 and can be pivoted through the opening 25.
The gate element 26 is normally held closed by the spring 42, which also normally holds the pattern bars clear of the teeter bars so that the slide may move to and fro on the base 10, being limited in its motion by the stop member 23 and the pawl 45. A player would normally hold the base in his left hand with his thumb against the support or rack 30 while with his right hand he moves the slide 18. If the teeter bars in the four test locations match the setting of the corresponding pattern bars, the motion of the support under this thumb pressure can continue, thereby allowing the gate to open.
One solution for the puzzle presented by the position of the pattern bars indicated in the drawing is listed below. In this solution the binary 0 is taken as meaning that the teeter bar 21 has its end resting in the groove 20, that is, is down, while a binary 1 is taken as meaning that the teeter bar 21 has its end up or resting on the upper surface 19 of the higher side rail 12. While the teeter bars are not identified separately, their positions are listed in order as the slide is moved back and forth:

it is to be noted, of course, in table I above that a move is only possible when a teeter bar 21 is down (0) at pattern bar 34, down (0) at pattern bar 35, up (1) at pattern bar 36 and down (0) at pattern bar 37 and, in fact, all of the teeter bars indicated for those test positions have precisely those positions or values. Similarly, the slide can only be moved past the first pattern bar 34, Le, past the stop member 23, when the teeter bar required to be past that first pattern bar is up (I); a look at table 1 indicates that for those moves e.g., where a teeter bar is positioned to the left of the first pattern bar 34 it isinfactup(l).
A further characteristic of the puzzle in accordance with my invention can be noted in table I. A move of position in a teeter bar is only possible at the gate element position 25. Accordingly the teeter bar positions indicated for each move differ from the preceding and succeeding moves by only one teeter bar and in each case by the position of the teeter bar at the gate position 25. It is also apparent from the table how the slide must be moved both forward and backward to position the desired teeter bar at that gate position.
it is left to the reader and to the player of the game to figure out possible solutions for the 15 other puzzles that may be defined by the four pattern bars employed in this specific embodiment, as well as solutions that may be utilized with other embodiments having less or more teeter bars or pattern bars.
Accordingly, it is to be understood that the above-described arrangements are merely illustrative of the application of the principles of my invention. Numerous other arrangements may be devised by those skilled in the art without departing from the spirit and scope of my invention. Thus various other physical shapes may be utilized for the teeter bars and the pattern bars, provided that the teeter bars and pattern bars are blocked in one test position and allowed to mesh towards each other in another test position. Similarly different shapes and mechanisms for the gate element will be obvious to those designing different physical implementations of my invention.
Further while the specific embodiment disclosed utilizes removable pattern bars, whereby a plurality of different puzzles can be formed, it is to be understood that a puzzle in accordance with my invention could utilize a set grouping of pattern bars, as is embodiments wherein the pattern bars and their support rack are molded as a single piece.
