GEM SETTING.

Application filed May 28, 1924. Serial No. 716,399.

This invention relates to an improved setting for gems; and the object of this invention is to provide a channel-shaped wire or member having narrow, inturned edges and 5 a gem-supporting strip or carrier member adapted to have the gems positioned therein "and then slid, with the gems therein, into the channel member, the gems being then locked in position in the supporting member 10 by the inturned edges of the chan'neljmember.

l Vith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in th appended claims.

In the accompanying drawings Figure 1 is a perspective view of my improved gem setting in the form of a bracelet.

Figure 2 shows a length of channel wire in which the gems are held.

Figure 3 is a sectional end view of the catch plate which is attached to one end of the bracelet channel to serve as a stop for the end gems of the row.

Figure 4 is an edge view showing the snapengaging end of the catch plate.

Figure 5 is a view partly in section and showing the end plates which serve as a stop for the end gems and also showing the snap catch which is employed for connecting the ends of the bracelet together.

Figure 6 is a top view showing a short length of carrier member having pockets into which the gems are set. I

Figure 7 is a sectional side elevation of the carrier member illustrating the gem-receiving pockets as swaged into the gemsupporting strip along its length. to Figure 8 shows one of the gems in a pocket of the carrier member secured in the channel member and held in position by the inturned edges of the channel.

Figure 9 illustrates a method of mounting the gems, which is that of depositing them progressively into pockets in the carrier memher, then advancing the carrier member to carry its gem into the channel where it is locked in the pocket by the oppositely-projecting edges of the channel.

Figure 10 shows abar pin having gems set therein by the use of a pocketed'carrier, as illustrated.

It is found in the setting of gems, into a bracelet, bar pin, or other. piece of jewelry of a similar character, of advantage to prois a detailed description of one embodiment of my present invention:

lVith reference to the drawings, 10 designates the channel bar or wire which ispreferably formed of sheet stock bent up into channel or trough shape having a bottom wall 11, side walls 12, and inturned lips or flanges 13 on opposite edges thereof. This channel strip or wire may be formed into any desired shape suoh as being bent into circular form which may be employed in the construction of a bracelet, or it may be formed straight and of a desired length to form a bar pin, as illustrated in Figure 10, or for any other purpose for which it is adapted.

In order to facilitate the setting of the pockets being connected by a web and of a shape to receive the backs or under portions of the gems 16 and the heightof the strip with the pockets is just suflicient when the gem is set therein to slide into the channel and cause the edges 17 of the gem to engage the under side of the inturned lips 18 of the channel member whereby the gems are securely locked in position in their respective pockets as soon as they are advanced into the channel.

In performing this setting operation, it is necessary to drop a gem into the first pocket of the strip then advance the strip to carry this gem into the channel and each successive gem is set in its pocket in this way and as each gem is deposited therein the strip is advanced thereby securely locking each one immediately after it has been deposited into its pocket and advanced into the channel permitting very rapid work even by unskilled operators and when finished the gems are firmly and accurately set.

llU

When a bracelet is constructed in the manner described, it is found, in many instances, of advantage to provide a catch for releasing the ends to receive the hand of the wearer and to do this, I have soldered a plate 18 between the flanges on each end of the bracelet, which plate is thickened on its end such as at 19 to extend down into the trough or channel to )provide a stop against the end gem 20, (see igure 5). Also one of these plates is provided with fingers 21 which serve to receive the shoulder 22 of the snap 23 whereby when the ends ofthe bracelet are carried in toward each other, the snap enters the space 24 and its shoulder 22 snaps up over the fin ers 21 thereby locking the ends of the brace et together.

In releasing these ends it is only necessary to press down the member 23 and the bracelet ends may be separated.

My improved gem setting is extremely simple and practical in construction, is inexpensive to manufacture, is very quickly made and provides a setting which is strong and durable.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

Y 1. A gem setting comprising a bottom wall, side walls, inwardly-extending retaining flanges on each side wall, a carrier memher having cups engaging the lnner face of the bottom wall, a web connecting said cups,

and gems seated in the cups and overlapped a in 1 1111' e sur ace 1e b and eng'tg g tle d 1 f ot tl flanges.

2. A gem setting comprising a bottom wall, spaced side walls extending therefrom, inturned edge flanges .on saidside walls, a carrier member having a plurality ofpockets of a depth substantially that of said side walls, a web connecting said pockets, gems in said pockets having portions extending thereabove and between said flanges and portions overlapped by said flanges to hold gems carried therein in said channel slideway, portions of the gems being overlapped in said pockets by the said flanges to hold them in position.

In testimony whereof ture.
