KEY-RING.

Specification of Letters latent.

Patented June is, rare.

To all whom it may concern:

Be it known that I, SIDMAN RUSKIN, a citizen of the United States, residing at Chicago, in the county of Cook and State oi Illinois, have invented certain new and useful Improvements in Key-Rings, of which the following is a specification.

lvly invention relates to key rings of the type or general form shown in Letters Pat- 22l,57l, granted November 11th, 1879, to George JV. Jopson, and its object is to enable the keys carried on the ring to be segregated in such manner that a particular key, or group of keys frequently used, may be readily identified and distinguished from other keys also carried on the key ring.

My invention consists in the construction and arrangement of parts whereby I attain the foregoing object and advantages, the novelty whereof is more particularly pointed out in the appended claims.

In the drawing forming a part of this specification, Figure 1 illustrates a key ring closed and carrying several keys, one of which is attached to one end of the ring and the other grouped in the main central opening; Fig. 2 is a plan view of the central parts or body; Fig. 3 a View of one of the two slotted disks; Figs. 4, 5 and 6 views of the complete ring showing the disks in various positions to which they are turned in putting keys on and ofi the ring.

The same letters of reference indicate the same parts in all the figures.

The body of the ring consists of a central plate A, formed with a main key loop B of any suitable contour, the key space within the loop B of the plate merging into a relatively narrow slot 0 of arc-shaped outline arranged approximately concentrically of a pivotal point in What may be termed the head of the key ring, which slot terminates in the key opening a at the outer edge of the head. The opening a also communicates with the small or supplementary key loop 7) formed in the head of the plate A, extending in a curved path opposite the slot 0, and terminating in an extension C of the head. outside the periphery of the locking disks hereinafter described. These disks, of which there are two in number, pivoted to the plate A, one on each side, are of such diameteras to cover the slot 0 and the inner portion of the slot 7), excepting as portions of'such slots are uncovered by radial notches (Z formed in such disks when the disks are rotated. The extension C is provided with. a small perforation c in which is secured one end of a short chain E, the other end of the chain being provided with an open link With the construction described it is obvious that when the disks (which are independently movable) are both turned to the position shown in Fig. 4, the bow or ring of a key held in the main loop B of the body of the key ring may be drawn within the notches (Z of the disks D and carried along the path of slot 0 in the head of the body to the opening a, as shown in Fig. 5, so that the key may be removed; and a reverse operation will serve to place a key on the key ring. It is also obvious that with the notches (Z in the position shown in Fig. 6, the link 7 of the chain E,Vwhich is designed tocarry whatever key may be selected as most frequently used, as, for instance, a house key or office key, may be similarly manipulated to detach such link from the loop ;,and vice versa. When the keys are upon the ring the disks D may be turned to difierent positions, as indicated in Fig. 1, after which it is practically impossible for the keys to become accidentally detached.

If desired, the chain E may be dispensed with and the selected key or keys be directly secured in the supplemental loop 6, (see Fig. l) in the same manner as the less frequently used. keys carried upon the main loop B of the ring. In either case provision is made for placing one or more selected keys in a detached location, whereby they may be readily found without searching through all the keys carried upon the key ring, thus enabling the user to identify a particular, frequently used key without looking at it, or in the dark.

I claim:

1. A key ring comprising a body formed with a main loop and a supplementary loop and a key opening and with slots connecting said opening with said main and supplementary loops respectively, and a rotatable notched disk pivoted on said body and arranged to progressively uncover said slots a portion at a time while leaving the main and supplementary loops uncovered.

2. A key ring comprising a body formed with a main loop and a supplementary loop and a key opening and with slots connecting said opening with said mainland supple mentary loops respectively, and a pair of in dependently rotatable notched disks pivoted on said body and arranged to progressively uncover said slots a portion at a time when copies of thin patent may be obtainedvtor 4-. A key ring comprising a body plate formed with a main loop and a head portion connected with said loop, said head portion being in major part circular in outline and provided with an extension formed with a supplementary loop and projecting outside the circle and away from the main loop, and said head being formed with a key opening and with slots connecting said opening with said main and supplemental loops respectively, and a rotatable notched diskpivoted on said head concentrically therewith and arranged to progressively uncover said slots a portion at a time when rotated.
