GEM OR STONE SETTING Application filed March 8, 1926. SeriaI No. 93,193.

This invention relates to improvements in the art of gem setting for rings or the like, and it is the principal object of the invention to provide a setting or mounting for the gems and stones, allowing a quick and ready exchange of the stones.

Another obj ect of the invention is the provision of a novel and improved locking means for exchangeably locking the stones of for instance emblem etc. rings to the setting.

A further object of the invention is the provision of a stone setting or mounting adapted to be conveniently held on a ring body, while allowing a suitable exchange of the stones or gems.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be more specifically defined in the ap pended claim.

In the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is a face view of a ring embodying the present invention on an enlarged scale and partly in section with the stone locking elements in their open position.

Fig. 2 is a similar view with the locking elements in their engaged position.

Fig. 3 is a plan view, partly in section on line 33 of Figure 2. r

Fig. 4 is a section on line 44 of Figure 1.

Figs. 5 and 6 are detail views of a key or looking member in side elevation and edge view respectively.

Fig. 6 is a plan view of a ring body member, open for the reception of the setting.

Fig. 7 is a front elevation thereof.

Fig. 8 is a front elevation of a modified form of the setting frame receiving the stones or gems.

Fig. 9 is a section on line 99 of Figure 8.

Fig. 10 is a detail front elevation of a gem or stone.

Fig. 11 is an end view thereof.

The invention for the purpose of illustration is shown in connection with a finger ring having a body 10 of any desired material and shape. In the oppositely located edges 11 and 12 of its open crown a plurality of notches or recesses 13" are provided for the mounting of the gem or stone setting proper, comprising a frame 13 having undercut edges to form flanges 14, and a somewhat depressed seat 15 for the stone or gem 16, preferably having a hole 17 in its center if the stone is t0 be used for decoration with emblems, initials, etc. The side edges of the stone or gem are undercut or formed with grooves 18 and 19 respectively.

On one of its sides the seat 15 is formed with an elongated slot 20 passing entirely through the material of the seat for the introduction of a key 21 having a tongue 22 at one end adapted to engage the recess'18 of the gem 16. At its opposite side or end, the key 21 is formed with a hook 23 adapted to engage a hook 24 at the inner end of an arm 25 on seat 15 having its outer end attached to frame 13 and which is curved intermediate its ends, as at 26, to engage with its rear edge the groove 18. It is obvious that the arm 25 is a yielding arm, the curved portion 26 of which is adapted to enter the groove 18 of the gem 16 and be retained therein by the engagement of the hooks 23 and 24 when the key 21 is in its effective locking position, as shown clearly in Figure 2 of the drawing. As shown in Figures 5 and 6, the body of the key 21 has a raised portion 27 and a depressed portion 28 slotted for engagement by arm 25 to prevent lateral play of the same while a projection 29 on the key is adapted to engage the slot 20 in the seat 15 to allow a removal and introduction of the key by means of a suitable tool from the rear of the frame 13. At the side opposite to the arm 25, the frame has attached to its inner side edge above the seat 15 a loop or staple 30 adapted to engage with its inner edge the groove 19 of the stone, while its outer ends are suitably formed with the ring body. However, it will be clear that the setting or frame 1.3 may be attached to the ring body in any other suitable way as by soldering etc.

The stone and frame are assembled in the following manner: The stone is placed into the frame 13 and the hooks 23 and 24 are pressed by the stone slightly towards the right, so that upon release of the stone, they will press the left hand groove in the edge of the stone into firm engagement with the loop 30, and the stone Will be firmly held thereby and by the engagement of the hooks in the groove at the opposite side edge of the stone in its place on the frame or the seat formed therein for this purpose, as will be apparent.

The operation of my device will be clearly understood from the above description and it is clear that, while I have shown and described the preferred form of my device as an example of the many Ways to practically construct the same, such changes as come within the scope of the appended claim may be made in the general arrangement and inthe construction of the minor details of the ring setting without departure from the spirit of my invention or the principle invo'rlved.

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

Ino'ombination with a gem having-grooves in the side edges thereof; of a setting therefor comprising a frame, a staple carried on one side thereof fitting in the groove at one side edge of the gem, a key movable in said frame and having 'a tongue thereon adapted to engage the groove in the opposite side edge of said gem and means in said frame adapted to engage said key in one position to lock same. and correspondingly said gem against casual displacement, said last mentioned means also engaging the last mentioned grooveof said setting, as and for the purposes descri-bed.

In testimony whereof I affix my signature.

VALENTINE MARTINKEV'IGH.
