BENT WIRE PUZ ZLE Filed March 18, 1946 2 Shets-Sheet 1 A T TOR/VEYS Patented Sept. 6, 1949 BENT WIRE PUZZLE Albert J. Gore, Washington, D. 0., assignor of forty-five per cent to Philip Larner Gore Application March 18, 1946, Serial No. 655,196

Claims. 1

My invention consists in a new and useful improvement in puzzles of that type which comprises wire members which may be interengagecl to present the problem of their disengagement as the solution of the puzzle. In devices of this kind, it is quite common to provide two members for interengagement, each of which is formed into a plurality of convolutions of a single wire, and one member has its ends united while the other member is so fabricated as to provide a gap between the ends of the wire of which it is composed, so that one member is a closed element and the other member is an open element in the combination.

The peculiarly novel features of my improved puzzle are the relative proportions of the closed and open members, the peculiar relation and character of the convolutions at their ends, and the form and relative positions of the ends of the open member.

While I have illustrated in the drawings and have hereinafter fully described one specific embodiment of my invention, it is to be distinctly understood that I do not consider my invention limited to said embodiment but refer for its scope and understanding to the following description and claims appended thereto:

In the drawings, wherein the same reference characters represent the same parts in the several views:

Fig. 1 is a front elevation and Fig. 2 is a side elevation of the closed member;

Fig. 3 is a front elevation and Fig. 4 is a side elevation of the open member;

Fig. 5 is a front view of the closed member, as in Fig. l, and a side view of the open member, as in Fig. 4, the members being in one interengaged position;

Fig. 6 is a similar view of the same members in a second interengaged position;

Fig. 7 is a similar view of the same members in a third interengaged position;

Fig. 8 is a side elevation of the open member and a cornerwise view ofthe closed member in a fourth interengaged position; and

Fig. 9 is a View similar to Figs. 5, 6 and 7 of the members in, a fifth interengaged position.

As illustrated in the drawings, my improved device consists in a closed member A and an open member B, each one formed of a single wire, circular in cross-section, the gauge of the two wires being the same. As shown in Figs. 1 and 2, the member A has straight portions l and 2 joined at their upper ends by the spiral portion 3 comprising three semi-circular parts 3-a, 3 l

and 3--c, whereof 3-a and 3c, which are spaced apart to form a throat T somewhat wider than the gauge of the wire (Fig. 2) form the upper half, and 3b forms the lower half of the circle 3:r (Fig. 1). The portions I and 2 diverge and merge at their lower ends into semi-circular parts la and 2a respectively. It will be noted (Fig. 1) that while the parts Ia l and 2a have radii of the same length, they are not concentric due to the divergence of the portions I and 2, the centers of the parts I-a. and 2-0, being symmetrically spaced on either side of the vertical axis of the member A. It will also be noted (Fig. 2) that the portions I and 2 diverge also in the plane at right angles to the plane of Fig. 1. As clearly shown in Fig. 2, the parts I-a. and 2-a are disposed in intersecting vertical planes so that the tongues Ib and 2-1), which extend upwardly from the parts I ,-a and 2a respectively, somewhat overlap the lower ends of the portions l and 2. It will be noted that the relation of the tongueslb and 2b to the portions I and 2 is such that in the plane of Fig. 1 the joints formed by I, 2-b and Z, Ib are of -a thickness equal to twice the gauge of the wire, and in the plane of Fig. 2 the thickness of the joints is only about 1 the gauge. It will also be noted that at the point where the parts I-a and 2-0. cross the vertical axis of the member A the vertical diameter of the joint is that of the gauge. The contacting surfaces of the portions I and 2, parts la and 2a, and tongues Ib and 2b are permanently united as by solder or any other suitable medium, thus making the member A the closed member of the combination.

As shown in Figs. .3 and 4, the member B has the straight portions II and I2 joined at their upper ends by the spiral portion I3 comprising three parts I3--a, I3-b and I3-c, whereof IS-a and I3c, which are spaced apart to form a throat T of substantially the same width as the throat I' of the member A, form the upper half and part I3b forms the lower half of an approximately circular coil |3--a:, the diameter of which is equal to the diameter of the circle 3-:r formed by the spiral portion 3 at the upper end of member A. The portions II and I2 are approximately parallel and merge at their lower ends into the co-axial similarly curved parts I I-a and l2-a respectively. their centers lying in the vertical axis of the member B. It will be noted (Fig. 4) that the portions II and I2 diverge in the plane at right angles. to the plane of Fig. 3. As clearly shown in Fig. 4, the parts I I--a and I2-a are 59 disposed that their longitudinal axes lie in the divergent planes of the longitudinal axes of the portions H and I2 respectively, thereby forming the throat T" which, due to the divergence of the portions II and I2 is approximately twice the width of the throat T, thus making the member B the open member of the combination.

Fromthe foreg oing description of the structure of the members A and B, it will seen that the members can be interengaged, moved into and out of a variety of relative positions and disengaged by passing their straight and curved portions through the throats T, T and T". There will now be described a methodby which the members may be interengaged, brQ'llghtinto several relative positions shown in Figs. 5, 6, 7, 8 and 9, and then disengaged. In this "method, the members are interengaged by the introduction of the open member B into the closed member A at the lower end'oi theme nber A (Fig, and are disengaged by removal of member B from member A atth'e -11pper, end of member AfiFig. 1). It is obvious that the interengagement, movement to the illustrated positions and disengagement can be efi'ected reversely vijz,interengagement at the upper end and disengagement at the lower end of memberA by effecting the steps of the q i l Hold member vertical in position ,shown in Fig. 1. Hold member B horizontal. Pass part I la over and part 112% under parts 1a and 2-0; at the vertical axis of member A, 1-11 and 2a passing tnr ug'n throat 'I" of member 1B. Pass portion I through throatTT Swing member B downwardly into vertical position, parts I a and 2'-;a being passed through rifng fl "3n:, the members being interengaged as shown in Fig. 5. U v

Pass part l3 -b through throat T oi member "A. pass part 3b through throat "I" of member Move member B upwardly to right until it is vertical, the members A and B being then interengaged asshownin Fig. 7. 1
