AIR v PURIFYING DEVICE Filed oct. 9, 1945 WZUAM J. Bl/SS WW M A7' TOP/VEYS.
Patented Feb. 1, 1949 sito 2 Claims.
This invention relates to air purifying devices and more particularly to a device for deodorizing and disinfecting air,
A main object of the invention is to provide a novel and improved air purifying device which is of very simple construction, very inexpensive to manufacture and which is very effective in removing undesirable odors irom the atmosphere where employed.
A further object of the invention is to provide an improved deodorizing and disinfecting means employing a current of air and a deodorantcarrying screen member, and wherein said screen member is readily replaceable after a period of use.
Further objects and advantages of the invention will appear from the following description and claims, and from the accompanying drawings, wherein:
Figure 1 is a perspective View of a Ideodorizing and disinfecting screen constructed in accordance with this invention.
Figure 2 is a horizontal cross-sectional view of the screen member of Figure 1.
Figure 3 is a perspective view of a portable air purifying unit according to this invention, parts thereof being broken away to show the interior construction.
Referring to the drawings, II designates a screen member of generally rectangular shape comprising a pair of channel shaped vertical side frame elements I2, I2, abottom pan member I3, a top pan member I4, and a pair of center vertical brace members I5, I5 respectively disposed between the iront edges and the rear edges of the top and bottom pan members, the parts being rigidly secured as by Welding to form a stiff frame. Vertical brace members I5, I5 are generally V-shaped in cross-section to provide extra rigidity to the frame.
Disposed between the vertical brace members I5, I5 and received within the side channels I2, I2 are a plurality of sheets of Wire mesh I', and between the adjacent sheets of wire mesh I6 is a iilling of deodorant and disinfecting material Il such as paradichlorobenzene crystals or the like. The deodorant material is loosely packed so as to provide substantial porosity for the screen and to allow air to be blown therethrough without excessive resistance.
Screen II is adapted to be positioned across the outlet duct opening of a conventional ventilating or air conditioning system to thereby disinfect and deodorize air as it is blown into a room. Where no source of owing air is initially available, a portable unit, such as shown, in Figure 3, may be employed. Said unit comprises a (Cl. 2l-7ll) 2 frame I provided with a bottom plate i9 upon which an electric fan 29 is mounted, the forward end of the frame being formed with a grille 2l. Provided between grille 2l and fan 2l] is a space 5 formed with vertical guides 22 adapted to slidably receive a deodorant screen I l and to support it in vertical position across the path of the air current produced by fan 20. In operation, air
is blown through screen II and is thereby de- 10 cdorized and disiniected.
Frame is is provided with a carrying handle 23 for moving the unit from one location to another.
Ordinarily the screen will be effective through several months of use. When the deodorant material has been substantially evaporated or otherwise dissipated, the screen may be easily removed and replaced by a fresh screen.
While certain speciiic embodiments of an air purifying device have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention other than as dened by the scope of the appended claims.
What is claimed is:
1. An air purifying screen comprising a pair of inwardly facing vertical side frame members, a horizontal bottom pan secured to the lower ends of said side frame members, a horizontal top pan secured to the top ends of said side frame members, a vertical front brace member secured centrally 'between the front edges of said top and bottom pan, a vertical rear brace member secured centrally between the rear edges of said top and bottom pan, said vertical brace members being V-shaped in cross-section and facing inwardly, a plurality of sheets of wire mesh positioned between said vertical brace members and 40 received within and perpendicular to the side frame members, and a filling of Vloosely packed deodorant material between adjacent sheets of Wire mesh.
2. The structure of claim l, and wherein The following references are of record in the fue of this patent:
