SPECIFICATION forming part of Lettere Patent No. 694,033, dated Februery 25, 1902.

Application led July 11, 1901. Serial No. 67,823. (No model.)

T0 all whom it may concern.-

Be it known that I, WILLIAM E. STUBBs, a citizen of the United States, residing at the city of Chester, in the county of Delaware, State of Pennsylvania, have invented certain new and useful Improvements in Puzzle Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which Figure l is a plan view; Fig. 2, a section on line m Fig. l, showing also one of the pins in a hole; Fig. 3, an enlarged elevation of a pin; Fig. 4, a diagrammatic plan showing a solution of the puzzle.

'Ihe nature of this invention is a puzzle device consisting o'f a block or board having a series of equidistant parts, such as holes therein, arranged Vin parallel equidistant rows and a cord or the like having secured thereto a series of parts, such as pins, a predetermined distance apart, the puzzle to be solved being to connect the parts consecutively of said cord with certain of the parts of the block in such manner thateach of the last-mentioned parts shall loe engaged by or connected to one of said parts of the cord, respectively, as hereinafter described.

Referring to the accompanying drawings,

l is a block of wood or other suitable material, which is provided with equidistant holes 2, occupying equidistant parallel rows arranged in the form of a square, as shown. 3 is a cord, to which are firmly secured equidistant pins 4, that are adapted to be entered into said holes.` The distance apart of Ithe pins is equal to the length of the diagonal line of a rectangle formed by six of said holes-that is to say, the distance, for example, between the corner hole marked ct in Figs. 1 and 4 and the hole marked b, asvalso the hole marked c.

In endeavoring to solve the puzzle the first 'pin upon the cord is thrust into one of the holes 2-as, vfor example, the corner hole a the next pin into either the hole b or c, and so on, with the object ofplacingin like manner a pin in every hole'of the series, each pin in succession being entered into a hole whose distancey from such pin is equal to the distance from the latter to the next pin. To do this is not easy, but may require many trials, for the reason that one is likely to soon arrive at a point when the hole or holes in which the pin then in hand should be entered, or might have been, has been occupied by apreceding pin.

I have shown diagrammatically in Fig. 4 one solution of the puzzle, in this case the starting-point being at' the hole a, and the ending at hole b.

I prefer to make the pins of spring-wire bent into the form shown in Fig. S-that is, with a head ein, that'is clamped to the cord, and legs a, bowed, as shown, and at their widest point of greater width than the diameter of the holes 2. Thus the pin may be readily entered into the latter, thereby forcing the legs toward each other, whereby it (the pin) is held sufficiently to preventliablity of being drawn out when the cord is manipulated in working out the puzzle.

Although in the particular' illustration of.

my device shown in the drawings the block is provided with thirty-six holes, six rows of six holes'each, occupying a square, there may be a greater or less number arranged to form a square or rectangle. The greater the nurnber of holes and corresponding pins on the cord the more diiiicult itwill be to solve the puzzle.

I further remark that my device may be made invarious forms without departing from the essential principle of the invention. For

example, in lieu of the holes 2 and pins 4 v there may be pins fastened to the board l and having projecting eyes secured to the' cord, that are adapted to be engaged over the pins, lthe essential in this regard being that the block shall have parts or devices corresponding to the said holes and the cord, parts, or devices corresponding to the pins.

In practice I would in order to keep together the vblock and cord permanently secure one end of the latter tothe block at a proper point-as, for example, at or near the corner hole a.

*Having thus described my invention, I claim as new andV desire to secure by Letters Patentl. A puzzle device com prisingablock hav ving equidistant part-s arranged in equidistant parallel rows, and a cord or the like, having parts corresponding in number to the said parts of the block, and whose distance apart roo is equal to the length of a diagonal line of a rectangle formed by or more of the parts of said block; the said parts of the cord being adapted to be engaged with and disengaged from The parts of the block, substantially as and for the purpose set forth.

2. A puzzle device consisting of the block having the series of equidistant holes therein arranged in equidistant parallel rows, andthe cord, or the like, having the series of pins secured thereto whose distance apart is equal to the length of the diagonal line of a reotangle formed by six or more of said holes, substantially as set forth.

3. In a puzzle device of the character recited, the combination of the block having the series of equidistant holes therein arranged in equidistaut parallel rows, the cord, or the like, the series of equidistant pins se-` cured thereto and having the bowed spring- Shanks adapted to engage said holes, substantially as and for the purpose set forth.

In testimony whereof I have hereunto afxed my signature this 29th day of May, A. I). 1901.
