SPECIFICATION forming part of Letters Patent No. 629,213, dated July 18, 1899.
' Application filed April 6,1899. Serial No. 711,999. (to model.)
'rings designed, primarily, for holdingv keys and like articles and adapted to be carried in the pocket, although it is well adapted for other uses.
The objects of the invention are to providea simple device which when closed will present no corners or points to wear or catch and tear the garments of the user and which while permitting the keys .to be placed thereon with the greatest facility will nevertheless be secure against accidental opening. Referring to the accompanying drawings,
Figure l is a perspective view, of a key ring and guard constructed in accordancewith my present invention. Fig. 2 is a similar view illustrating the manner of opening and closing the ring. Fig. 3 is a cross-section through the lapping ends.-
Like letters of reference in the figures indicate the same parts.
The ring proper, A, is preferably formed of relatively stifi but still somewhat resilient metal, such as tempered steel, and its two ends are beveled on their adjacent faces, as at (L, to form a relatively long lap-joint,
the two extremities, by reason of the bevelingof the meeting faces, lying close to the body' of the opposite end, and thus presenting no points or projections when the ring is closed. The overlapping ends are preferably flattened somewhat transversely of the radii, or the body of the metal forming the ring at this point is of somewhat greater thickness from side to side thanfron top'to bottom, and this formation may extend throughout the overlapping portion, but preferably is for only a short distance, as at D in Figs. 1 and. 2.
The set of the material forming the ring tends to hold the ends together when they are lapped in normal position; but when their positions are reversed with relation to each other the tendency is to hold the ends apart, as shown in dotted lines. In order now to open or close the ring at will, I provide a guard or pendant B, having in its end a keyhole-slot b. The round end of the slot is of such diameter as to permit the ring to slip through and rest loosely within it at any point, even when open, while the narrow end of the slot is of such width as to just take in the lapped ends of the ring when slipped transversely thereon, as shown in full lines in Fig. 2Q
With the guard in the last-mentioned position, if it is given a half-turn, as indicated, the positions of the lapped ends will be reversed with relation to each other, thereby opening the ring for the reception of keys or other articles. When these have been placed upon or removed, a reversal of the operation of opening the ring will bring the ends back into their normal position, closing the ring.
In the preferred form the edge of the gnard= plate is scalloped; but it is obvious that it may be given any attractive, ornamental, or fanciful shape, as desired, and also in this preferred form the body of the metal forming the ring, except at the lapped portion, as before stated, is of such cross-sectional area as will prevent the entry of it into the narrow portion of the keyhole-slot. Thus the guard is held out of operative relation except at the portion D, where it will move the overlapped ends, The ring and guard may be made of any preferred metal, dependent upon the value and style .of ring desired to be pro duced. 1
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A key-ringhaving overlapping ends bevthe transverse diameter of the overlappedends being greater than the vertical diameter, in combination-with a guard-plate havin g a keyhole-slot the narrow portion of which fits said meeting or overlapping ends on their shortest diameter and is narrower than their greatest diameter, substan tially as described.
2. A key-ring having overlapping end s beveled on their meeting faces to present a smooth contour on the outside, the set of the mate- 'rial tending to hold said beveled faces together when in contact and to separate the ends when their positions are reversed, the
transverse diameter of the overlapped ends being greater than the radial diameter and the radial diameter less than the diameter of the body of the metal forming the ring, in
v combination with a guard-plate having a key
