SPECIFIGATION forming part-'of Letters Patent No. 753,266, dated March 1, 1904.

Application led April 21, 1302.

To all whom t may concern:

Be it known that I, ORRTL L. HUBBARD, a citizen of the United States, and a resident of Waukesha, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Puzzles; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to that class of game apparatus which is designed for the working out of problems; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accompanying drawings and subsequently claimed.

In the said drawings, Figure l is a plan view of .my said apparatus with the sliding blocks set in the preferred position to present the problem for solution. Fig. 2 is a like view showing the position of said blocks when the problem has been solved. Fig. 3 is a transverse vertical sectional view through the gameboard, taken on the line 3 3 of' Fig. 2 and ,showing one of the sliding blocks. 2 5

My said apparatus is designed for the working out of various problems, that selected for illustration in the present case being the safe passage of two trains 'on a single track by the aid of a turn-table of just sufficient capacity to hold an engine and coach or two coaches at any one time.

Referring to the drawings, b represents a game-board having a longitudinal -groove c with obliquely-undercut side walls extending from end to end thereof, the open ends of the grooves being closed by the end pieces c', a of the board. At the center of the said board the same is formed with a circular recess extending below the plane of the bottom of the groove c and formed with a straight annular wall for the reception of the turn-table cl, which latter is formed with a groove e through the upper portion thereof corresponding exactly i-n depth, width, and inclination of its side walls with the described groove c in the board, so that when the turn-table is Serial No. 103,870. (No model.)

disposed as shown in the drawings the groove 0 e 0 is continuous from one end of the board to the other. To facilitate the turning of said turn-table d, the same is preferably supplied with an opposedpairof screw-eyes ff. Fitf ting within the described longitudinal groove c e c are two series of sliding blocks g g, all of equal size, having oblique side walls fitting against the oblique side walls of the groove, so that after the said blocks have been fitted to place within the groove (which isv easily done by first lifting out the turn-table e) the said blocks cannot be lifted out of the groove, owing to the described side walls of said groove being undercut, as stated. Inthe preferredrform of this device herein illustrated the turn-table is shown revoluble on a Xed central pivot which is of equal diameter throughout, so that the turn-table can be readily lifted out, as described, for placing the blocks within the groove; but in order to guard against the problem being fraudulently Worked through such lifting out and to render the device incapable of being tampered with I construct the same in such cases with a head or flange t' to the pivot it, as shown in dotted lines at i in Fig. 3, and in this style the blocks g g are pushedin from one end of the board before the end .piece t on that end is secured to place.

The described blocks g g represent the individual members of two railroad-trains and are lettered and numbered to indicate this more clearly and to show that the proble-ms lare correctly solved. One train here represented is composed of engine 1, baggage-car 2, and coach 3, and the other train is made up Similarly the precise number of blocks in each train is non-essential so long as there is only room on the turn-table for two of the blocks g at one time and only space betweenA the turntable and adjacent end of one of the trains for one block g and on the opposite side of the turn-table only space for two of said blocks g between the turn-table and the adjacent end of the other train.

As stated, various games may be played and various problems worked out with this apparatus; but to work out the particular problem hereinbefore referred to and to change the blocks from the position shown in Fig. 1 to those shown in Fig. 2 without removing any block from the groove c e c the operation is as follows, referring to the blocks g g simply by the numerals they bear: First, engines 1 and 4 are pushed on the turn-table Z and latter turned half around. Next, push back 4 off i table d and run back 1 to block 5 and draw same on table, which now holds 1 and 5, and turnthe table half round. Next, push 5 off table and against 4, and then run 1 to 6 and draw both 1 and 6 on table and turn latter half round. v Then push 6 off table and against 5 and run 1 back to 7 and draw both 1 and 7 on table and turn latter half round. Then engine 1 pulls 7, 6, and 5 across and past table to and within the just-emptied space in the groove on that end. Then engine 4 draws 2 on table, and the table holding 4 and 2 is turned half round. Next, run 4 down to 3 and pick up same and carry both to table, pushing 2 off table against 5 and leaving 4 and ,3 on table and turning the table half round.

Next, engine 4 pulls 3, 2, and 5 across table, leaving 2 and 5 on table, with 4 and 3 in the just-emptied space, and the table is turned half round. Then engine 4 pushes 2 off table and leaves 3 and 5 on the table, and the table is turned half round. Then engine 4 pushes back 5, 3, and 2 and picks up 6 and draws them forward, leaving 6 and 2 on table and 4, 5, and 3 in the lately-emptied groove-space Y and table is turned half round. Then engine 4 pushes 5 and 3 back and picks up 6 and pulls same off table, with 4, 5, 3, and 6 now in groove and 2 only on table. Now engine l backs 7 against 2 and pushes 7 and 2 forward, leaving 7 and 2 on table and 1 in groove-space on that side, and then table is turned half round. Then engine 1 pulls 2, 7, 6, and 3 in opposite direction, leaving 6 and 3 on table and 1, 2, and 7 in groove-space, and table is l turned half round. Then engine 1 pushes 6 of table toward 5, leaving 7 and 3 on table and 1 and 2 in groove-space, and table is turned half round. Then engine 1 backs up 2 against 3 and draws 2 and 3 to the end of the groove-space, as shown at the right-hand end of Fig. 2, leaving 7 on table, and table is turned half round. Then engine 4 pushes 5 and 6 back, pushing 7 o' table and putting 6 on table and leaving it there and drawing 5 0E, with 4 and 5 in groove-space, and table is turned half round. Next engine 4 pushes 6 off table against 7 and leaving 5 and 4 on table, and table is turned half round. Then 5 is pushed of table in groove-space, leaving 4 on table, and the table is turned half round. Then engine 4 pulls 5 on table, so that4 and 5 are on table, and table is turned half round. Then engine 4 moves ofi1 table into groovespace, leaving 5 on table, and table is turned half round. Then engine 4 backs 5 against 6, and then said engine 4 pulls 5, 6, and 7 forward across table to end of groove-space, leaving 4, 5, 6, and 7 just as shown at the left-hand end of Fig. 2, and the problem is solved. The blocks are restored to their original position by the reverse of this operation, when the device is made so that turn-table CZ cannot be lifted olf its pivot L, or, if the board is made to permit such removal, then the turn-table is lifted oftn and the blocks pushed into the central space that said turn-table had occupied and replaced block by block in the original positions shown in Fig. 1.

It will be understood that while the front and rear ends of the blocks are herein to be distinguished by the way the numerals and names on same are marked they may be otherwise indicated, either by words or initials indicating front and rear or by arrows or other arbitrary marks which I have not deemed it necessary to show; but in the proper solution of the problem it is essential to distinguish these ends, so that the. trains when the problem is solved will be made up with all the parts represented by the blocks heading in the same direction throughout a train.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patentl is- A game apparatus, comprising a board having'a longitudinal groove across the same, said groove being closed at each end, and the side walls of the groove being obliquely undercut, and said board having a central circular recess extending to a depth below the plane of said groove, in combination with a revoluble turntable itting in said central recess and formed IOO IIO

with a transverse groove coinciding in width,
