ENnLEss BAND PUZZLE Filed July 27, 1962 INVENTOR.

f m MMYW United States Patent 3,235,262 ENDLESS BAND PUZZLE Ernest Franki, Middieboro, Mass., assignor to Winthrop- Atkins Co., Inc., Middleboro, Mass., a corporation of Massachusetts Filed .luly 27, 1962, Ser. No. 212,816 7 Claims. (Cl. 273-155) This invention relates to a device for amusement and/or educational purposes of the kind in which two sets of bands are arranged at right angles to each other and, by movement relative to each other, may be manipulated to correlate certain data on the bands to produce pictures and/or present the solutions to problems and the like.

The principal objects of the invention are to provide a device of the foregoing kind designed to effect economies in manufacture and assembly and to provide for ease of manipulation and attractiveness.

As herein illustrated, the device has spaced parallel, rectangularly arranged pairs of supports and endless bands entrained about the supports for movement thereon at right angles to each other, characterized in that the upper and lower runs of the bands, situated between one pair of supports, have contact with each other in a common plane throughout their length between the supports and alternately pass above and between the pairs of runs of the bands entrained about the other pair of supports. The device comprises a rigid frame of rectangular configuration having recesses in its four sides within which are disposed the supports on which the bands are entrained and is constructed of upper and lower halves joined in a median plane, the adjacent sides of the halves containing journals for receiving the ends of the supports. The upper half has a window opening of rectangular shape which forms a frame for the web of woven bands and the lower half has a back which closes it.

The invention will now be described in greater detail with reference to the accompanying drawings wherein:

FIG. l is a plan view of the device broken away in part at one corner;

FIG. 2 is an end elevation;

FIG. 3 is a transverse section taken on the line 3 3 of F IG. l;

FIG. 4 is a longitudinal section taken on the line 4 4 of FIG. l;

FIG. 5 is a fragmentary bottom view taken adjacent one corner;

FIG. 6 is a vertical section taken on the line 6-6 of FIG. 1;

FIG. 7 is a side view of an endless band; and

FIG. 8 is a plan View ofthe band.

The device is of the kind having a plurality of endless bands supported at right angles to each other for movement relative to each other to bring portions of the several ban-ds into such position as to produce a picture or the like, to spell words, or `to give the answers to a numerical problem.

The device is made up of a pair of rigid, rectangular frame .halves 1G and 12 adapted to be placed together in abutting engagement, open side to open side, to support two pairs of rollers 14-14 and 16-16 at right angles to each other on which endless bands 18 are entrained.

Each frame has spaced parallel end members 20-20 and spaced parallel side members 22--22 at right angles thereto which contain rectangular recesses 24--24 and 26-26 respectively, providing spaced parallel shoulders between which the rollers 14-14 and 16-16 are mounted parallel to the e-nds and sides. Each of the frames and 12 has a semicilcular opening 28 in the shoulder portions 25 and 27 which collectively provide circular openings at the ends of the recesses for receiving the reduced lCe end portions 30 of the rollers 14 and 16. The two frame halves have interftting recesses and pins 32 and 34 (FIG. 6) respectively, in their corner portions adapted to be frictionally engaged to hold the frame together following assembly. The frame 10 contains a rectangular display opening 36, while the frame 12 preferably has a closing back panel 38.

The frame halves 10 and 12, as herein illustrated, are made of a rigid plastic molded to shape, of suitable color and of decorative appearance, however, it is to be understood that the frame may be fabricated of any suitable material such as composition board, sheet metal or wood. The rollers likewise may be made of plastic, metal or wood. The surfaces of the rollers are preferably smooth enough so that rotation of the rollers in manipulating a specific band will not be imparted to the adjacent bands.

The bands 18 (FIGS. 7 and 8) are comprised of a flexible material such as paper covered on one surface with a plastic film or coating. For example, the picture which is to be the subject matter of the puzzle is printed on a sheet of paper whereupon the printed surface is coated with a tough, flexible plastic which will withstand repeated flexing and rubbing without cracking or peeling. In accordance with conventional practice in the construction `of this kind of puzzle, the surface of the band is divided up into small areas 4G which carry specific portions of the picture or other data to be assembled by manipulation of the bands thereon. The bands, as shown, are of endless construction and, in accordance with an important aspect of the invention, are mounted on the rollers supported by the frame in the following manner. The frame halves are separated, placed face down and the bands 18, extending lengthwise of the frame (FIG. 4) of which four are shown herein, vare mounted on the rollers 14--14 side-by-side in one half whereupon the bands which are to be disposed transversely of the frame (FIG. 3) are folded flat, that is, so that the runs between the ends have contact with each other and then one end, starting from left to right, is drawn across both runs of the rst band next between the runs of the second band, then across both runs of the third band, and nally between the runs of the fourth band. The next transverse band is drawn between the runs of the first band, then across both runs of the second band, then between the runs of the third band, and finally across both runs of the fourth band. The third and fourth bands are repeats of the rst and second. As shown in FIG. 4, viewed from right angles, only the upper runs of the longitudinal bands are woven with respect to the transverse bands, passing, as shown herein, over the iirst transverse band, under the second, over the third, and under the fourth. The lower runs travel in a straight undeviatng plane beneath all of the bands. After the transverse bands have been set into place, the rollers 16-16 are inserted through the loops at the ends of the transverse bands and tted into the openings 28 whereupon the other half of the frame is fitted into place so as to hold the rollers in position. This mode of assembly involves a minimum amount of weaving, permits assembly of the closed loops in contrast to prior structures in which open bands had to be woven through and joined one-by-one on the iinished article in order to effect the weaving and thus makes manufacture and assembly much less expensive which is an important consideration in a low-price article of this kin-d.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modiiications and equivalents which fall within the scope of the appended claims.
