DECOBATIVE JEWEL:
Specification of Letters Patent.
Patented Jan. 2, 1917.
Application filed August 15, 1914. Serial No. 856,973.
T0 alZ whom it may concem:
Be it known that I, WALTER DA. RYAN, a subject of the King of Great Britain and Ireland and the Isle of Man, residing in North Adams, State of Massachusetts, have invented certain Improvements in Decora tive Jewels, of which the following is a specification.
One object of my invention is to provide a gem or jewel particularly adapted for use in decorative or ornamental lighting systems, the invention contemplating jewels of such composition and construction as Will produce the highest possible decorative effect.
A further object of the invention is to provide a decorative jeWel with means whereby the number and size of the spectral images produced shall be increased and the colors of said images made more intense and brilliant than has hitherto been considered possible.
It is further desired that the jewels constructed according to my invention shall be of high projecting or carrying power, in order that they may be effective, even though widely separated, for outlining buildings, signs, or the like, or for interior decorations.
These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in whioh,
Figures 1 and 2 are respectively a side and rear elevation of a decorative gem or jewel constructed according to my invention.
I have discovered that for decorative purposes, such as outlining any desired object such as a building, for illuminating signs or making them visible, or for interior decorations, gems or jewels of any suitable or desired cut, when combined with a suitable source of light, Will give the best possible decorative efiects only when they have an index of refraction of from 1.66 upward and this is due to the fact that the colors of the spectral images produced by the various facets of the jewel are composed of relatively long spectra in which the different colors are widely separated or extended so that each of them is comparatively pure and brilliant. Moreover, I have found that the glass used for my decorative gems should preferably contain a high Proportion of lead, although this 1s by no means necessary, since with a suitable source of light, such as an electric projector, it is only necessary for the index of refraction to be sufliciently high in order to 1nsure the purity and consequentlv the heightened ornamental effect of the spectral images. ,1 have also discovered that the decorative efiect of such jewels as above described is very greatly increased, say to the extent of 40% or more, if a plane mirror be placed immediately adjacent the apex of each of them. Thus, as shown in the drawings, 1 represents a jewel or gem having what is known as a brilliant cut and supported in a holder made in the form of an annular frame 2 of thin metal including a suspending stem 3 and a suitable number of clips 4: wherehy the jewel is held in position in said frame. In addition, the frame has a rearwardly projecting and inclined extension 5 terminating in a circular piece 6 including projecting fingers 7 at its edge Which serve to support a plane mirror 8 immediately adjacent the apex of the jewel 1 in a position substantially perpendicular to the centerline thereof. Under conditions of use, such a device serves to increase the number of spectral images produced by a source of light in front of the gem, from 40% to 50%, and it should be noted that for the purposes of my invention, the jewels should not be less than 14 millimeters in diameter, since While this dimension is preferably greater than that given it cannot be less if the desired results are to be obtained. If the arn1 5 should be so adjusted that the mirror is carried to the rear of the apex, thon, While the number of spectral images is greatly decreased, the ew still ormed are of greatly increased intensit and are refiected at widely divergent angles past the sides of the jewel.
It is to be noted that the mirror employed by me may in some cases be in forms other than plane, and while I have described it as mounted adjacent the apex of the jewel or gem, it is to be understood that in cases where the latter.is out so as to have no true apex on its rear side, the mirror nevertheless would loe mounted adjacent said rear side, being placed so as of the jewel for any desired distance.
I claim:
1. A decorative gem consisting of a body of glass having a rearwardly projecting to 'extend laterally apex; a mirror; and means independent of the gem for supporting said mirror adjacent said apex.
2. The combination of a gem in the form of a body of faceted glass; a holder for freely suspending said gem; and a mirror carried by the holder atthe rear of the gem.
3. The combination of a gem consisting of a body of facetcd glass; a holder for the same consisting of a ring having a suspending arm; a second arm projecting rearwardly from the ring; and a mirror carried by said second arm adjacent the rear portion of the gem.
4. The combination of a gem consisting of a faceted body of glass having a -rearwardly projecting apex; a metal holding ring extending around the gem adjacent its part of largest diameter; an arm projecting rearwardly from the ring; and a plane mirror carried by the arm immedianely adjacent the apex of the gem.
5 A decorative gem consisting of a body of glass having a rearwardly projecting apex; a mirror; and means for supporting said mirror adjacent said apex.
6. The combination of a holder consisting of an integral sheet mental structure including a ring having a suspending arm and provided With jewel engaging clips, and a second arm projecting from said ring; with a jewelcarried by said clips; and a mirror carried bythe second arm.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
ALTER DA. RYAN.
