down upon the device.

JAMES A. LOVELAND AND MERRITT-L. FISHER, O'F KALAMAZOO, MICHIGAN.

LIGHT-DEFLECTOR.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed March 22, 1920. Serial No. 367,792.

lights and the like; the primary object of the invention being to provide a deflector which will cast light from any suitable source down upon the floor so that the glare from the source of light will not annoy one looking Another important object of the invention is to provide a device of this nature includ-' ing a body portion which consists of a plurality of downwardly and outwardly flaring deflector members which are maintained in spaced relation whereby the source of light located in the body portion may be passed downwardly thereof.

Another object of the invention is to rovide a device of the above nature including a base which may be readily detached from or attached to a suitable light support.

A still further object of the invention is to provide a device which embodies a compact construction which may be subjected to severe usage and still retain its rigidity, and one which is inexpensive to manufacture and highly eflicient in practice.

Other ob ects and advantages of the inven-v tion will become apparent during the course of the following description.

In the accompanying drawings forming a part of the application and wherein like numerals are employed to designate like parts throughout the several views.

Figure 1 is a side elevation of the invention, parts thereof being broken away to show the assemblage of parts.

Fig. 2 is an enlarged fragmentary section through one side of one of the deflectors and Fig. 3 is a bottom plan of the top of-the deflector. v

In the drawings, wherein for the purpose of illustration is shown the referred embodiment of my invention, t e numeral 4 in the present instance designates a circular lamp base upon which is attached a vertically disposed incandescent lamp 5.

The base of the deflector consists of an annular band 6 having oppositely disposed threaded apertures 7 therein for the reception of set screws 8 which are adapted to be screwed into engagement with the lamp base to maintain the band in engagement therewith. The upper marginal edge of the band 6 is equipped with a pair of oppositely disposed inwardly extending ears 9 disposed at right angles to the band, and are aper tured for a purpose to presently appear.

The body portion 10 of the deflector housing consists of a plurality of superposed deflector elements 11 each of which consists of a band 11 which flares outwardly and downwardly as is clearly shown. The upper marginal edge of each band or deflector 11 is provided with oppositely disposed inwardly extending ears 12 each of which is apertured as at 13. The apertures through the ears in the deflectors and base band 6 are adapted to aline for a purpose which will presently appear.

The cap 14 is aninverted imperforated bowl shaped element the marginal edge of which is provided with oppositely disposed inwardly extending apertured cars 15. These ears are adapted to rest upon the ears 12 of the uppermost deflector 11 whereby a bolt 16 may bepassed through the ears 16, 12 and 9 of the top, deflector and base respectively, it being understood that one bolt is used for each'series of ears.

In order that the deflector 11 may be spaced one above the other and the lowermost deflector spaced from the base 6, a plurality of spacing sleeves 17 are mounted upon each bolt 16. Each sleeve has its lower end engaging the upper surface of an ear carried by the lower element and its upper end engaging the under surface of an ear carried by one of the deflectors 11.- A nut 18 is of course threaded upon the lower end of each bolt 16 and abuts with the under the proper position.

From the foregoing description, it will be face of an ear 9 to retain all of the parts in obvious that such deflectors may be advantageously used in motion picture theaters by placin the deflector over a pilot light locate at each aisle, upon steps, or any other place where a person is apt to stumble and fall. Due to the compact and rigid construction Y of the deflector, parties. accidentally bumping into the same will not damage or weaken the construction. It is also obvious that the deflector maybe read ily disengaged from the lamp base by loosening the set screws and lifting the deflector from the lamp base.

The foregoing description and the drawings have reference to what maybe considered thepreferred form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, material, dimen sions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described our invention,

what we claim as new and desire to secure by Letters Patent is 1. A device of the class described comprising a body portion including a plurality of superposed spaced deflectors, a source of light within the body portion, each deflector having an inwardly extending apertured portion, and means extending through said apertured portions of the deflectors for securin them in position. I

2. 2 device of the class described comprising1 an annular band provided with an lnwar y extending apertured portion, a

plurality of "superposed spaced deflectors superposed outwardly flaring spaced deflectors, each of which and the base is provided with a ertured ears, spacing elements between t e-ears and deflectors and base, and means extending 7 through said ears and spaced elements for securing-the parts to gether.

In testimony whereof we aflix our signatures in presence of two witnesses. 1
