WITNESS I /lvl/E/vmnfs'iita JOHN F. SCOTT, 0F INDIANAPOLIS, INDIANA.

EYnsHiELD DIFFUSER. I

To all whom it may concern:

Be it known that I, Joux l", Sco'rr, a citizen of the United States,'residing at lndianapolis, in the county of Marion and State of Indiana, have invented a new and -useful Eye-Shield Diffuser. of'which the tionable, and even dangerous, to the eye; in

addition, the distribution of light froiu these nitrogen lamps is not uniform, so that a streaked illumination is produced bythe di- A rect rays therefrom.

It is the object of my-'present invention to provide a simple form of eye shield, and

preferably a diffuser, for the electric incandescent lamp, and especially for the modern high brilliancy lamps, although the device is not limited to these lamps; and to make this device readily applicable to all the standard forms of lamps so that it can be applied inexpensively to existinginstallations.

In carrying out my invention, I provide a holder which can be mounted on the lamp bulb itself, preferably at the base thereof,

and from this holder suspend an inverted dome-shaped 'member vwhich extends around the lower and larger end of the lamp bulb and iiiterce ts the direct rays of light from the lamp.y refeiably, this inverted domeshaped member is of translucent glass, so that it acts at once to diffuse the rays of light from the lamp andV permit their passage in a diffused condition, and as a. reflecf, tor for producing an upward illumination which vcan be reflected downward by a suitable reflector for indirect vor semi-indirect lighting. However, the inverted dome- Shaped member may be wholly opaque, in which case the diffused transmitted light is eliminated entirely and the lighting is wholly indirect.

AThe single figure of the accompanying drawing is a perspective view of a lamp equipped with my eye shield diffuser, also showing in dotted lines the lamp socket and one form of reflector.

Specification of Letters Patent.L

raten-ted Feb. zo, 1917.

Application filed March 22, 1915. Serial No. 16,041.

The incandescent electric lamp 10 is shown i as of the modern nitrogen type, having the usual base 11 which is providedV withl a threaded portion 12 for fitting into the standard socket 13. able reflector il may be mounted above the lamp, as on the socket 13.

lf desired, 'any suitil holder 15 is mounted on the base 11 of the lamp 10. This holder comprises a suitable portion for surrounding. 'and' clainpwire, the ends of this helix projecting therefrom and being bent downward to form supporting fingers 17, the vlower ends 18 of which are bent outwardly. vThe fingers 17 extend obliquely, substantially parallel to the wall of the lamp bulb 10. The fingersl'S extend through diametrically opposite holes 19 in an inverted doine-shaped member 20, which is thereby hung from \the holder 415.

lThis dome-shaped member extends around the lower end of the lamp bulb 10, being 4spaced therefrom, and intercepts the downward rays of lightl therefrom and also any sideward rays below the horizontal. 'Pref erably this inverted dome-shaped member Q0 is made of a translucent glass, which ing itself upon, the base 11.--this clamping lportion being shown as a helix 16 of spring permits the passage of the rays of light' from the lamp 10 but diffuses and modifies them to make the .distribution of light more uniform .and preferably to eliminate the rays of higher frequency, such as the injurious ultra-violet rays. Glass which will do this is now known. Preferably the in* asr ner surface ofthe inverted, dome-shaped member is a polished surface so that there is a considera le reflection of light upward toward the reflector 14, which in turn reflects the light downward to produce indirect lighting. If desired, the' inverted domeshaped member 20 may be opaque instead of translucent, thus producing a. wholly indirect lighting; but at present I prefer to make lsuoli member translucent, so that the resultant lighting is se1niindirect.

This eye shield diffuser andits holder may be applied to any standard lamp, by

lsimply fixing the clamping'parts 16 of the holder 15 on'the base 11 of the lamp, and bringing the fingers 1T inward so'that the bent tips thereof register with the holes 19, and then'allowing such fingers to sprinr outward so that the bent lower ends 18 may 11C pass through the'holes 19 and thus support the eye shield diffuser 20.

I claimas my invention: 1. An eye shield diffuser, comprising a support having a clamping portion for mounting on the base of'an electric inc/andescent bullo' and one or more downwardly projecting portions,4 said mounting being separate from the lamp socket, and an inverted dome-shaped member of translucent glass hung tree from the lower ends of said downwardly projecting portion or'portions and inclosing the lower end of the lamp bulb upon which said holder is mounted.

2. An eye shield diffuser, comprising a support having a clamping portion for mounting on an electric incandescent bulb and one or more downwardly projecting portions, said mounting being separate from Athe lamp socket, and an inverted domeportions, said mountingbeing separate from the lamp socket, and an inverted dome shaped member lullig freefroni the lower ends of said downwardly projecting portion orportions and .inclosing the lower end of the lamp bulb upon which said holder is l mounted.

4. An eye shield, comprising a support haring a clamping portion for mountirig on an electric incandescent bulb and one or more downwardly projectinglr portions, said mounting being separate from the llamp socket, and. an inverted dome-shaped member hung free by` points at its upper edge or rim from the lower ends of said downwardly projectingportion or portions and "inclosing but being spaced from the lower end of the lamp bulb upon which said holder is mounted. Y. 5. An eye shield dili'user, comprising a wire holder having a helical coil portion for'itting upon the base of an incandescent lamp and a pair of downwardly projecting fingers with rbent ends, and an inverted dome-shaped member of translucent material having holes for receiving the bent ends of saidngers, said dome-shaped member surrounding the lower end ot' the lamp bulb upon which said holder is mounted.

6. An eye shield, comprising a hol-der provided with means for mounting it upon an electric vlamp bulb and two depending and substantially opposite arms, and a dome-shaped member hung by substantially opposite-points at its uppercdge or rim from said two arinsmand inclosing the lower end of the lampv bulbfuponwhich said holder is mounted, said dome-shaped member having a reflecting interior surface.v

7. Au eye shieldv diffuser, comprising a` support having a clamping Vportion for mounting on the base ofY an electric incandescentbulb and ne or more downwardly projecting portions', said. mounting beingl separate fronrthe lamp socket, and an inverted dome-'shaped member of translucent glass hung freeby points around its upper edge or rim. `r

In witness whereof; I have hereunto set myhand at Indianapolis, Indiana, this twentieth day of March, A. D. one thousand nine hundred and fifteen.
