Abstract: A wire form puzzle is disclosed. The puzzle provides a dumbbell shaped capture element having a straight wire body having rings at the ends. An upper swing capture element provides a crescent shaped wire body having end rings attached to the straight wire body of the dumbbell shaped capture element. A lower swing capture element is similar to the upper swing, but smaller in size and is carried by the crescent shaped body of the upper swing. Four horseshoe shaped captured loops are carried by the lower swing capture element, but are removed from all the capture elements in the course of the puzzle's s solution. The horseshoe shaped loops have the characteristic of having a point, defined by the inner wire defining the horseshoe loop, that will pass into any of the rings, and also having the characteristic that the rings of the captive element will pass through the indentation between the legs of the horseshoes.

Abstract: A toy puzzle in the form of two shaped semi-rigid wire members, the first member serving as a handle and a support from which the second member may be hung in a variety of positions, depending on the skill of the holder of the first member. The first member is in the form of a Z-shaped member with a relatively short straight leg section joined to a relatively long leg section by a mid-section oriented at an acute angle to both leg sections, all sections lying in a common plane, and the free end of the long leg section having a grip and serving as a handle. The second member is formed of two opposed hook sections joined by straight sections bent at various angles, with all sections lying in a common plane and with the free ends of each hook section being bent in opposed directions from the common plane.

Abstract: A puzzle of the type having an openable loop with two internal subloops in the form of two single turn coils spiraling continuously into each other through semi-oval non-flat curves, and a closed loop with two internal subloops in the form of two double turn coils spiraling continuously into each other through semi-oval flat curves. The two loops, when interengaged in accordance with a predetermined position, present the problem of their disengagement without opening the openable loop. For quick disengagement of the two loops in case of mistakes in the solution of the puzzle or for interengaging the two loops in the predetermined position, the openable loop is formed with a hook and an eye so that it may be opened and closed.

The sleeves are slidably engaged over the respective ends of the open end horseshoes so that the chains can be removed and replaced as needed.

Abstract: A wire-form puzzle which requires a puzzle solver to remove and replace a heart-shaped wire-form element from a captured position on a U-shaped wire-form having ring tips through which extend a rod also having ring tips, by threading the wire-form element about and through the ring tips.

Abstract: The puzzle is of the type comprising a number of individual rings, each of which is loosely connected to one end of a short post, with all the posts being in turn movably anchored at their other ends in a common base member. An elongated closed loop straddles the post and passes through the rings in a uniform manner. To solve the puzzle, that is to remove the loop, a number of precise steps is required. These steps need to be repeated in reverse to replace the loop. In accordance with the invention, each post is made of two parts, namely: a rod and a cap. The cap has a slot opening through three sides for the transverse insertion of the ring into the cap slot, with the ring protruding from two opposite sides. The cap further has a blind bore which extends across the slot opening at the third side. When the rod is inserted into the blind bore, it not only carries the cap and the ring but also locks the ring within the cap slot.

Abstract: A wire puzzle comprising two elements. The first of such elements is a length of wire configured to include a plurality of serpentine loops, the entire length of wire forming a closed circuit. The second of such elements is a length of wire formed to provide at least three loops, the length of wire having a free end which terminates in spaced relation to a segment of the wire which has been bent to form the first of such loops and then the second. The wire segment, after formation of the first and second loops runs generally parallel to the segment terminating in the free end and thereafter forms the third loop about said first loop. By manipulation of the first element and its serpentine loops with respect to the three loops of the second element the two elements may be connected and disconnected without forcing.
