PUZZLE.

SPECIFICATION forming part of Letters Patent N 0. 470,717, dated March 15, 1892.

' Application filed July 20, 1891- Serial No. 400,100. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL STERNE, a resident of Albuquerque, in the Territory of New Mexico, have invented certain new and useful Improvements in Mathematical Puzzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

cent to which it is placed.

The invention has relation to a mathematical puzzle; and it consists in the matter hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a top plan; Fig. 2, a bottom plan. Fig. 3 is a diagrammatic representation, and Fig. 4 is a perspective of a detail.

In carrying out my improvement in puzzles I provide nine cubical blocks, each having one of the nine digits on every side. These digits have a special arrangement on each'block, as indicated in the illustration herewith, said arrangement being such that when the several blocks are placed as indicated twenty-eight triads of figures, each arranged in a straight line and each amounting to fifteen, will be discoverable.

Referring to Fig. 1 of the drawings, it may be seen that there are two diagonally-arranged rows, the sum of the figures of each of which equals fifteen, and also that there are six similar rows parallel to the sides of the blocks. Fig. 2 shows the same to be true in respect to the figures on the opposite faces of the same blocks.

The digits marked on Fig. 3 indicate those on the four sides of each block, the proper position of each digit being on the side adja These furnish twelve rows, each amounting to fifteen, which twelve added to the eight on the tops and the eight on the bottoms make twenty-eight in all.

For convenient inspection of the several sides of the blocks I provide a holder which will allow them to be seen from above and below and on the sides. This holder consists of a main stem 1, having preferably a handle 2 and three branches. The blocks have perforations orpassagesepassingthroughthemandthrough their centers from each side. By means of these theblocks can'be placed on the branches 3 in any desired order. They are placed sufficiently far apart to permit each block to be independently turned on its supporting-wire and also-to permit the reading of the figures on the adjacent sides of the three series of blocks. The wires 3 are made long enough to permit the blocks to be sufficiently separated thereon for convenient reading of the figures on the adjacent sides in each series. The figures on the inner side of the whole can be inspected without disturbing their order bysuitably elevating or tilting the holder. The blocks on any wire 3 can be removed and replaced in different order with respect to each other or with respect to the direction of the sides of one or more of them.

Then the device is in use, if the blocks rest upon a level surface, every side except one of every block can be inspected. By moving the blocks, as stated, any desired change of order can be easily effected.

Preferably the wires 3 will have such size and form with references to the passages 4 that the cubes will be held from movement by friction. If desired, the branches 3 may be made of spring-Wire and slightly curved in the direction of theirlength toinsure sufficient friction. In such case each wire may be curved or bent at different points.

Having thus described my invention, what I desire to secure by Letters Patent is- 1. The combination of marked blocks arranged in parallel series and constituting a puzzle with a holder having several parallel rigid branches, each branch detachably supporting blocks and each block apart from all others, substantially as set forth.

2. The combination of marked blocks constituting a puzzle and a holder having a main SAMUEL STERNE.
