Patented Feb. 18, 1930 PATENT OFFICE JACQUES W. D. CHESNEY, OF CHICAGO, ILLINOIS MEANS FOR PROJECTING ULTRA-VIOLET SUNLIGH'J. RAYS INTO BUILDINGS A lication filed May a, 1926. Serial No. 190,290.
My invention relates to an improved means for making available the beneficial effects of sunlight in enclosed rooms, with substantially the. same effect and benefits, as are to be derived therefrom when out of doors.
It has long been known that the action of sunlight upon the human body, out of doors, has been stimulating and helpful in a marked degree, and that in many cases it has demonstrated curative properties. In later years, scientific research in connection with light rays generally, and the suns rays in particular, has disclosed the presence in the category of rays generally called light rays,
of rays of too short a wave length, and other rays of too long a wave length, to produce any effect of visibility, as far as the human eye can discern, the rays of too short wave length being known as ultra-violet rays and the Q waves of too long wave length being known as infra-red rays. Investigation has shown that the beneficial effect of sunlight on the human body is due very largely to these ultraviolet and infra-red rays. Many attempts 23 have been made to produce ultra-violet rays and infra-red rays artificially, to avail of their beneficial effects where the action of sunlight cannot be had, and with considerable success. In producingthese rays artixo ficially however, it has been found that besides the true ultra-violet and infra-red rays, possessing biologic value, other rays are also produced which are not only not helpful, but are abiotic in their effect. a It has now been definitely ascertained that many conditions of malformation and malnutrition in the human body are traceable directly to insufficient effect thereon of ultraviolet rays, resulting in defective metabolism, particularly of the element calcium audits compounds, for example rickets and other defects of bone structure and many diseases, for example tuberculosis, cancer, asthma and other ills of the pulmonary type.
While the beneficial effects of ultra-violet against inclement weather, the material 0 and infra-red rays from sunlight are freely available outdoors, many persons from the nature of their occupation are confined more or less closely indoors and are not free to avail themselves of these effects. Furthermore, it has been established that glass of ordinary construction, although it freely transmits through it, light rays of visible wave length, is practically opaque to ultraviolet and infra-red rays, which results in building interiors, althou h well lighted, being practically devoid o the rays referred to. This largely accounts for the general condition of anemia commonly occurring in persons of indoor occupation.
' It is the object of my present invention to make available indoors, and without the difficulty and expense incident to producing them, ultra-violet rays and infra-red rays, by providin means for collecting them with other rays rom sunlight, and concentrating and reflecting them through suitable apertures in the walls of buildings into the rooms inside the building, where they are referably diffused to increase the area 0 their influence. In connection with devices of the kind described, I provide where necessary or advisable, screens or shields of special material to protect the interior of the buildin 76 these screens or shields being transparent to ultra-violet and infra-red rays. In this way I make available within the walls of the building, the beneficial effect of these rays without any expense in producing them, the so rays being thus available for the occupants of the building, whether for the purpose of maintaining them in good condition and health, thus fortifying them against the attack of disease, or in cases of disease, treat- 3:; ing the skin with said rays, since it will at once be appreciated that ray baths may be effectively given indoors although this is not entirely feasible outdoors.
My invention will best be understood by reference to the accompanying drawings showing a preferred embodiment thereof in which 1 illustrate in vertical sectional view a window of ordinary construction in the wall of a building and the construction and arrangement of my concentrating, reflecting and diffusing devices employed to project the desired rays into a room inside of a building wall.
As shown in the drawings, I indicate the wall of a building at 10, the floor of a room in the building at 11, the ceiling of the room at 12 and a window in the wall 10, at 13. The window 13 is provided with lower and upper sashes 14 and 15 arranged to slide vertically in guides in the window frame in the usual manner. In carrying out my invention with a window of the construction described, the upper sash 15 is lowered sufficiently to permit the projection of a beam of rays horizontally between the upper edge of the sash and the inner surface of the upper portion of the window frame. A first reflector 16 is pivotally connected with the window frame 17 and secured in desired angular position by means of a slotted bracket- 18 pivotally connected with the window frame and secured also at its slotted portion by means of a clamping screw 19 to a lug 20 carried by the under surface of the reflector 16.
The reflector 16 is preferably of metal having a cylindrical upper surface which is concave, to receive rays of sunlight that may fall upon it as indicateddiagrammatically by the lines 21. The degree of curvature of the concave surface of the reflector 16, is such as to concentrate the reflected rays as indicated at 22, upon the lower surface of a second reflector 23 mounted on the upper part of the window casing, this second reflector being also concave on its reflecting surface and of cylindrical conformation. The reflector 23 is also preferably metal and serves to direct the rays 22 falling upon it, in practically a parallel beam as indicated at 24, through the opening between the upper sash and the upper portion of the window against a third metal reflector 25 secured to the upper portion of the window frame inside of the room, this third metal reflector being convex and of cylindrical conformation so as to diffuse the beam of rays 24, to different parts of the room as indicated by the lines 26. Each of the reflectors described is preferably as long as the window is wide, to the end that the entire opening between the upper sash and the window frame ma be utilized to transmit the desired rays into the room. Each of the reflecting surfaces of the several reflectors is preferably coated with material which is non-absorbent to ultra-violet and infra-red rays, for example chromium. If preferred the reflectors may be made of aluminum, duralumin, magnalium, or dirigold, either with or without a special reflecting surface of chromium or other material capable of reflecting the ultra-violet and infrared rays, since these materials are themselves reflectors of such rays.
The reflecting devices described may be employed either with direct sunlight or with skyshine and in using the device, the reflector 16 is adjusted to most effectively receive the beam of rays 21 depending upon the location of the principal source of said rays at the time. The amount of the rays collected is determined of course, by the extent of the reflector 16, and the degree of diffusion of the rays in the room is determined by the degree of ourvature of the reflector 25.
To facilitate the use of my devices in cold weather, I provide a screen or shield 27 to be placed across the opening between the upper sash and the upper portion of the window casing, consisting of a suitable frame and a thin sheet of material across it, which is transparent to ultra-violet and infra-red rays, for example celluloid, albumen, gelatin or collodion, and where albumen or gelatin is used for this purpose, it may be weather proofed in any desired manner for example by the application of tannic acid, or formaldehyde. By having the material in the frame 27 quite thin, it offers practically no resistance to the flow of ultra-violet and infra-red rays through it, and the relation of the reflector 23 serves to protect the screen or shield from the elements.
WVhile I have for convenience illustrated the use of my devices in connection with a window in the outer wall of a building, it will be understoodthat they are not so limited, as they may be employed with equal effect for the purpose described, where an aperture is provided through the wall of a building in any manner, whether specially made for the purpose, or by establishing other openings through the wall, for example doorways and ventilating openings.
From the above it will be noted that I have produced an improved means for and method of introducing or projecting ultraviolet and infra-red rays of sunlight. whether in the form of direct sunshine or indirectly in the form of sk shine, (that is, diffused rays of sunlight re ected and refracted by that part of the atmosphere called the sky,) through the outside wall of a building into its interior, by providing an aperture in said wall ofl'ering no obstruction to the passage therethrough of said rays, thus making available in an enclosed space, the desirable effects of said rays upon the human body, whether such effects are chemical, as in the case of ultra-violet rays, or tonic, as in the case of infra-red rays; also, that to render said means and method practical, on account of all known building materials including glass, being opaque, or substantially so, to said rays, and the need of protecting any open apertures through outside walls from inclement weather conditions, such as rain, snow, wind and cold, my means and method permit the use of an aperture of relativel small cross-section by correspondingly con ensing and concentrating the beam of said rays passin through the aperture, and protecting sai aperture by one of the reflectors emp oyed, provision further being made to close said aperture against weather conditions if desired, y thin material transparent'to said rays. For convenience, I refer to saidrays in the claims as biologic rays, meaningb said term and limiting its meaning to eit er ,ultra-violet rays or infra-red raysor bothfderived d1- rectl and indirectly from silnlight.
W ile I have shown my invention in the particular embodiment above described, it will be understood that I;do not limit myself to this exact construction-as I may employ equivalents known to the art it the time of the filing of this application without departing from "the scope of the -appended claims.
