KEY-RING.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed April 14,1905. Serial No- 255,568.

To all whom it may concern:

Be it known that I, JAMES LYNN, a citizen of the United States, residing at Tyre, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in a Key-Ring, of which the following is a specification.

This invention relates generally to key rings, the object being to provide a simple and inexpensive construction of key ring by means of which large and small keys can be separated from each other, that is, all the larger keys held upon one side of the ring and the smaller keys upon the opposite side of the ring.

Another object of the invention is to provide a ring upon which the keys can be quickly and easily placed and removed by a person understanding the construction of the device and a still further object is to provide a key ring from which it would be almost impossible for the keys to become accidentally displaced.

With these objects in view my invention consists essentially in the employment of a ring divided at one side and having a finger projecting from the opposite side through the opening in the ring, said finger carrying one or more disks adjacent its free end, which disks are adapted to close the openings in the ring upon the opposite sides of the finger, said disk or disks being notched to receive the ring of the key, said notch being adapted to be brought into register with the opening in the ring at one side of the finger for the purpose of receiving the said bow of the key ring.

The invention consists also in certain details of construction hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification Figure 1 is a perspective View of the key ring constructed in accordance with my invention. Fig. 2 is a side elevation of said ring closed. Fig. 3 is a side elevation of the key ring with the disks arranged ready to re ceive the bow of the key to be arranged upon the ring. Fig. 4 is a face view of the ring with one of the disks removed. Fig. 43 is a view of said disk removed. Fig. 5 is a detail sectional view on the line 5-5 of Fig. 4.

In carrying out my invention, I make the ring A from any suitable material and any size desired, said ring being divided at one side and the ends turned inwardly and curved toward the center of the ring forming guides for the keys as most clearly shown at A in Fig. 4. A finger B, integral with the ring A, extends from the opposite side of the ring and projects through the opening of the ring and terminates in an eye B, by means of which the ring is connected to a key chain Adjacent the outer end of the finger it is somewhat enlarged as shown at B the opposite sides of said enlarged portion being curved inwardly as shown at B and outwardly as shown at B thereby producing two compound curve slots or openings upon opposite sides of the free end of the finger. Two circular disks 0 are pivotally connected to the enlarged portion of the finger B, by means of a rivet D, which passes through the central opening G, produced in the disk 0 and each disk has a peripheral notch O ,.which notch is constructed with reentrant portions C as most clearly shown in Fig. 4.

When it is desired to place the key upon the ring the disks are turned so as to bring their notches into register with each other 'and with the entrance of the curved opening'at one side of the finger, as shown in Fig. 2. The bow of the key is then introduced into the said notches and forced inwardly, said action serving to turn the disks so that they are brought into the position shown in Fig. 3. By this time the bow of the key will be in such a position that it can pass over the end A, of the ring and after the bow of the key has been passed over this end A, it is an easy matter to shift the said bow around upon the main portion of the ring, the disks turning freely upon the pivot, permitting said action and in so doing, they effectively close the opening at one side of the finger and thereby prevent the key from becoming accidentally disengaged from the ring.

By having the finger B connected to the ring at a central point, and projecting the same through the opening at the opposite side, the ring A is divided into two sections, each of which is adapted to receive and hold a number of keys and it will be found convenient to keep upon one side all the keys of a particular kind and upon the other side, all the keys of a different kind. Thus the keys can be divided into large keys upon one side and small keys upon the other, or office keys can be arrangedupon one side and house keys upon the other, thereby practically combining two separate key rings in one and employing a single locking means for closing both rings.

Thus it will be seen that I provide an exceedingly simple and efficient form of key ring, capable of operating in the manner herein before described and for the purposes set forth.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A key ring comprising a ring open at one side having downwardly projecting curved ends forming guides, 21 finger projecting from the opposite side between the said ends, and a notched disk pivotally connected to said finger adjacent its free end on a transverse pivot, said disk being adapted to force the key between the ends and the finger and to normally close the openings between the same, for the purpose described.

2. A key ring comprising a ring open at one side and the ends curved inwardly, a finger projecting from the opposite side of the ring through the opening and enlarged adjacent its free end, and the disks pivotally arranged upon transverse pivot, said disks having peripheral notches 10 the opposite sides of the enlarged portion of the finger, adapted to register with each other and with the openings said disks being notched as described. upon opposite sides of the finger for forcing the-key there 3.
