operating on the principle of the radiometer era EDWARD J'. HUNT, OF WEST ORANGE, NEW JERSEY.
ADVERTISING LAMP AND RADIOMETER.
Specification. of Letters Patent.
Application filed November e, 1917. Serial no. 209,967.
To all whom it may concern Be it known that I, EDWARD J. HUNT, a citizen of the United States, residing at Llewellyn Park, West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Advertising Lamps and Radiometers, of which the following is a specifica tion.
This invention relates to a motor device in which the moving or motor elements are caused to rotate upon their axes by the action of light.
The purpose of my invention is to provide a device which may be inserted within the inclosure of an ordinary incandescent lamp bulb and be combined with the filament support in a manner permitting the use of the usual lamp filament so that the light issuing therefrom shall cause the rotation of the several motor vanes. The apparatus is mainly useful for advertising purposes where it is desired to attract attention by means of movin objects. It is especially adapted for window or show case displays which arelighted at night, the apparatus serving as a source of light as well as a device to attract attention.
In the accompanying drawings Figure 1 is a side elevation of an apparatus embodying my invention; and Fig. 2 is a central cross sectional View through one of the sets of motor vanes.
The container may be in the form of the ordinary well-known incandescent electric lamp bulb, all of the parts being inclosed in the glass bulb 1, which must be exhausted and contain only rarefied air or gas.
The motor elements consist of a series of vanes 3, preferably four or more, which are silvered upon one side and blackened upon the other side, as by being covered with carbon, such as lam black, and carried by a central stem or s aft 4, rotatably' mounted in a yoke or support 6. These yoke supports are preferably made of glass and are attached to or a part of the stem 8 which supports the lamp filament 9.
I have illustrated three motor devices, but
it is evident that any convenient number" may be employed and that they may be placed at various angles with respect to the filament, not; only for design purposes, but also for the urpose of causing different amounts of lig t to reach the several sets of motor vanes. light falling upon the sides of the vanes covered with carbon is absorbed while that falling upon the opposite silvered sides is reflected and the reaction caused by the latter light rays results in the rotation of the sets of motor vanes about their axes. By
v varying the distance and angular relation of the several sets, different speeds result and thereby produce varying efl'ects.
In the day time this device may be used as an ordinary radiometer, the vane wheels being rotated by the sunlight, while at night the vanes are actuated solely by the interior light rays emanating from the filament.
I have shown only one form of the appa ratus, but it is evident that various structural' changes and modifications may be made within the scope of my claims without departing from my invention.
.I claim I 1. An apparatus of the class described, comprising a transparent sealed bulb or vessel containing a rarefied gas, a support within said vessel, sets of radiometer vanes carried by axles rotarily mounted upon said Patented Jano 7, 1919. v
As is well understood, the
support, and a lamp filament carried by'said support and having terminal connections mounted upon the outer wall of said vesse 2. An apparatus of the class described, comprising an incandescent lamp containing a rarefied or inert gas and provided with the usual filamentadapted to become incandes- EDWARD HUNT.
