FINGER-RING.

Specification of Letters Patent.

Application filed May 27, 1911.

atcnted Dec. 19, 1911. Serial No. 629,754.

To all whom it may concern.

Be it known that I, ALEXANDER Guannonn, a citizen of the United States, and a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Finger-Ring, of which the following is a full, clear, and exact description.

This invention relates to finger rings.

The object of the invention is to pr(Wide a finger ring having a spring band and a crown permanently secured to the band at one end of the latter, and having means for removably securing the free end of the band to the crown.

A further object ofthe invention is to provide a finger ring having a spring band, and a crown permanently secured to the band at one end only, of the latter, so that the ring can be slipped over an enlarged knuckle joint of a finger, without difficulty, while at the same time the free end of the band can be removably secured to the crown, so that the ring shall lit the finger with requisite closeness.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be. had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views, and in which- Figure 1 is an elevation of the ring, showing parts in cross section and parts in different positions in dotted outline; and Fig. 2 is an enlarged plan view of the crown and adjacent portions of the band.

Before proceeding to a more detailed explanation of my invention, it should be understood that frequently the knuckle joints of a finger are considerably larger than the thickness of that portion of the finger upon which the ring is worn, so that if the ring is large enough in diameter to pass easily over the joint, it fits too loosely upon the finger below the joint. To provide a ring which shall pass easily over the joint and at the same time fit snugly upon the finger, I employ a spring band per-ma nently secured to the crown or other setting, at one end only, and having at the opposite end a removable connection with the crown, so that the diameter of the ring itself can be increased by releasing the catch which holds the free end of the hand against the crown, so that the spring of the band itself, forces the end thereof away from the crown and enlarges the diameter of the band.

Referring more particularly to the drawings, 1 represents an open crown or setting of the usual form, having the prongs 2 by 11'] ans of which a gem or other ornament can be held in position in the setting. It will be understood that the form of the crown or setting can be varied at will, and that it does not constitute a material feature of my invention. 1 provide a spring band 3 of the usual .forn'l, either integral with the crown 1 or permanently secured thereto, at one end. The ring can of course, be fashioned from any suitable material, such as gold, silver, platinum, and the like. At the free end l, the band 3 has a tongue 5, preferably tapering in form and provided at the extremity with a laterally disposed integral spur 6. .-'\djacent to the tongue the band has shoulders 7 and 8, adapted to engage the side of the crown when the end of the band is locked in position. At the under side, adjacent to the end t of the band, the tongue has a transverse groove or recess 9. At the side adjacent to the free end of the band, the crown has an opening 10 therethrough, joining the usual opening 11 through the crown. The tongue 5 is movably arranged within the opening 11, and has its movement limited by the shoulders 7 and 8 and the spur (i which engage respectively, the outer side and the inner side of the crown. Thus, the spring band, when the catch is released, as will appear hereinafter, can spring away from the crown a distance substantially equal to the length of the tongue between the inner side of the crown and the spur (3, and the inner circumference of the band can be increased by substantially this length.

Arranged within the opening 11 of the. crown is a spring catch member 12 secured at the end 13 to the inner wall of the crown, by soldering or any other suitable means. The catch 12 is substantially annular in form and has the free end 14 arranged adjacent to the opening 10 and engages the groove 9 of the tongue when the latter is forced into the crown through the opening 10. The spring of the catch normally forces the free end 1 1 upwardly toward the tongue, so that when the latter is projected into the crown by pressing on the opposite sides of the band, the end 14 of the catch slips into engagement with the groove 9, to hold the end at of the band in position against the side of the crown. At the side, the crown has a second opening 15, preferably between two adjacent prongs 2, in which is slidably arranged a pin 16 integral with the catch 12 near the end 14:. By forcing the pin 16 inwardly, the catch 12 is depressed and the end 1 1 is forced out of engagement with the groove 9 of the tongue, thereby releasing the latter and permitting the band to spring outwardly to increase the diameter of the ring.

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

1. A finger ring having a spring band, a crown presenting a lateral opening and permanently secured to said band at one end thereof, said band having at the other end a tongue movably arranged in said opening and presenting a spur limiting the movement of said tongue, a catch for locking said tongue in said opening, and means located and operable outside of said crown for releasing said catch.

2. A finger ring having a spring band, a crown presenting a lateral opening and permanently secured to said band at oneend thereof, said band having at the other end a tongue movably arranged in said opening and presenting a spur limiting the movement of said tongue, a spring catch for locking said tongue in position in said opening with the free end of said band held adjacent to said crown, and means at the outside of said crown for releasing said spring catch.

A linger ring having a spring band, a crown presenting an opening at the side and permanently secured to said band at one end thereof, said band having at the other end a tongue movably arranged in said opening, a spring catch within said crown normally pressing against said tongue and engaging the same to lock said tongue in position, and means for displacing said spring catch to release said tongue, said means extending to and being operable at the outside of said crown.

4. A finger ring having a spring band, a crown presenting a lateral opening and permanently secured to said band at one end thereof, said band having at the other end a tongue movably arranged in said opening and presenting a recess, and a spring catch secured at one end within said crown and having the free end normally sprung toward said tongue, said free end being adapted to engage said recess to lock said tongue in position, said catch having an extension projecting beyond said crown, wherewith said catch can be operated to release said tongue.

5. A finger ring having a spring band, a crown presenting a lateral opening and permanently secured to said band at one end thereof, said band having at the other end a tongue movably arranged in said opening and presenting a recess, said band having a shoulder adapted to engage said crown, said tongue having a spur limiting the movement of said tongue within said openin and a spring catch secured at one end within said crown and having the other end normally sprung toward said tongue, said free end of said catch being adapted to engage said recess to lock said tongue in position, said crown having a second opening, said catch having an integral extension projecting through said second opening to the outside of said crown, said extension serving to operate said catch to release said tongue.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
