'N0.3'67,'896. Patented Aug-9,1887.





SPECIFICATION forming part ofLetters Patent No. 367,896, dated August 9, 1887.

Application filed March 529, 1887. Serial No.523-l847. (MorlcL) To all whom it may concern:

Be it known that], WILLIAM H. A. DAVID- sort, of Boston, county 'ofSuffolk, and State of Massachusetts, have invented an Improvement in Puzzle-Rings, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to a novel puzzle, which, when put together or completed, forms a rlng.

My improved puzzle-ring is composed of four independent loops, preferably of wire, each loop being made from a straight strip or piece of metal bent and soldered or otherwise fastened together. Two of the wires of which the loops are formed are each provided with a bend substantially at a right angle to the length of the said wire before the said wire is 2 jointed to form the loop, while the remaining two wires have a double bend. The four loops constituting the ring are loosely connected to-, gether, and one of the loops having a double bend has soldered or otherwise secured to it a star or other ornamentation, which, when the loops are put together to form a ring, occupies 'a position at the center of the ring, or where the stone is found in ordinary scal'rings.

Figure 1 shows my improved puzzle-ring completed, the .star or ornamentation being omitted to enable the positions which the different loops occupy in the completed ring to be more clearly seen; Fig. 2, a side-view of Fig. 1. Fig. 3 shows two strips of wire provided with a double bend. Fig. 4 shows two strips of wire provided with a single bend. Fig. 5 shows a single double-bent strip. Fig. 6 shows a singlebent strip. Fig. 7 shows the position the loops occupy when t 1e first step is taken toward completing the ring; Fig. 8, the second position; Fig. 9, the third position, and Fig. 10 the fourth position.

The completed ring shown in Fig. 1 is composed of four loops, A, A, B, and B, the said loops being preferably made from straight pieces or strips of metal, preferably in the form of a wire. The straight strips or pieces of wire from which the loops B Bare made are provided with a single bend, a, substantially at a right angle to the length of the said strip, while the straight strips, from which the loops hand.

A A are made, have a double bend, a. The bent strips referred to are rounded and have their ends soldered'or otherwise fastened together to form the loops A, A, B, and B, the

said loops being loosely connected together.

In practice the loop A at its bent portion (see Fig. 7) has secured to it a star, a, or other ornamentation, which may serve to mark or indicate the loop which is to be held by the operator when starting to complete the puzzle loop A in contact with the point x of the loop A where the loopsA A are held firmly between the thumb and the finger of the left The double bends a of the said'loops A A, crossing each other, form substantially a figure 8, one half, I), (see Fig. 8,) of the double bend of the loop A extending under the loop A. It will be noticed in Fig. 8 that the loops B B are shut within a closed circle formed by one half of the double bend of each loop A A. The other half of the double bend of the loops A A do not cross each other, but have an opening, 1), between them. The operator, continuing to grasp the loops A A, as described, or where the said loops cross each other, as stated, then turns the loops B B in opposite directions and substantially at right anglcs'to the loops A A, the bent portion a of each loop B B pointing downward, as shown in Fig. 9. The operator now takes the loop B and turns it toward the right, the said loop being turned until the bent portion a has passed between the two contiguous but not overlapping parts of the loops A A and below the point where the double bonds of the loops A A cross each other. (See Fig. 10.) The loop B is then turned toward the right until the bent portion a of the said loop is also below the point where the double bend of the loops A A cross each other. (See Fig. 10.) The bent portion a of both loops B B are now below the point where the double bend of the loops A A cross each other, and the operator then brings the bend (t of the loop B below the bend a of the loop B, as shown in Fig. 10, and when in this position the ring is completed and brought into the form shown in Fig. 1 by turning the loop B down and bringing it in contact with the loop A.

My improved puzzle-ring when put together in the form shown in Fig. 1 may be worn as an ornament the same as an ordinary ring, the star taking the place of a stone in an ordinary seatring.

I claim- 1. As an improved article of manufacture, a puzzle-ring comprising four loops connected together, two of said loops being provided with a single bent portion, a, and the other two having a double bent portion, a, one of the said double loops being marked to guide the operator in putting the ring together, substantial] y as described.

2. As an improved article of manufacture,

a puzzle-ring comprising four loops connected
