APPLICATION mm MAR- 28, 1918.

1,384,497. Patented July 12, 1921.




Application filed March 28, 1918. Serial No. 225,249.

To all to 7mm it may concern:

Be it known that I, Enwrn F. SYMoNs, a citizen or? the United States, residing at Sloatsburg, in the county of Rockland, State of New York, have invented certain new and useful Improvements in Key-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in key holders, and particularly to devices for holding door keys to prevent them being lost should they he accidentally withdrawn from the key holders or withdrawn therefrom by small children.

Another object is to improve the construction of a device of this character by means oi? which the device is connected to the knob spindle and to the key shank.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

in the drawing:

Figure 1 is a side elevation of my invention applied. to a knob and key of the door; v

Fig. 2 is an enlarged vertical section on the line 2--2 of Fig. 1;

Fig. 3 .is a perspective view of the device removed from the door and showing the position of the parts as they appear ready to be applied to the door knob and key.

Referring particularly to the accompanying drawing, represents a chain which may be ot any convenient length and havingsecured to one end a large ring 11 and at the other end a smaller ring 12. This smaller ring is or ordinary wire and is adapted to be passed around the shank of the key 18 and has its ends pinched together so as to prevent the ring from becoming detached therefrom. The ring 11 is formed preferably of resilient or springwire, and is open as clearly shown in the drawin The ends of the ring are extended from the ring in parallel relation and then bent laterally and inwardly to form a hook 14: on one of the ends, and an eye 15 on the other end. Engaged in this eye is an elongated ring 16 which is arranged to be passed over the hook and to engage therewith, after the ring has been snapped around the shank of the knob 17 The normal tendency of the ends of the ring 11 is to spring apart, thereby assuring the proper retension of the ring 16 in engagement with the hook.

The two rings fit the knob and key firmly enough to prevent their being removed therefrom accidentally, but loosely enough to permit of the easy turning of the knob and key.

It will thus be seen that should the key be pulled out of the key-hole, the same would be suspended by the chain, and danger of the same being lost obviated.

lVhile I have shown the upper ends of the ring 11 as comparatively far apart and the ring 16 of comparatively great length, I wish it understood that these ends of the ring 11 may be drawn closer together, so to more closely embrace the knob shank, by making the ring 16 shorter, if desired, and without departing from the spirit of the invention or the scope of the claim.

lihat is claimed is:

A key holder comprising a pair of resilicnt split rings oi": different diameters and each having an eye at its bight portion, a chain. secured at its ends to the said eyes, the larger ring having an eye on one of its ends and a hook on its other end, and an elongated loop pivotally ei'igaged in the lastnamed eye and arranged to engagewith the said book when the said hook end is flexed toward the eye end of the ring.

In testimony whereof, I atliX my signature, in the presence of two witnesses.
