E. F. HEALY ATOMIZER Filed June 19, 1940 Patented Feb. 10, 1942 ATOMIZER Elton F. Healy, North Attleboro, Mass., assignor to Evans Case Company, a corporation of Massachusetts Application June 19, 1940, Serial No'.'341,353
7 Claims.
The present invention is particularly directed to an atomizer in a form which may be convenient for dispensing perfume, toilet water and the like. It preferably is of a type which may be made small enough to be Conveniently handled, carried and manipulated. The construction is adapted to an atomizer which may be entirely operated by one hand. Thus it may be lifted and directed or aimed by one hand and the same hand may cause the liquid to be atomized while the device is being held and directed. The device is simple in Construction and consists of a relatively small number of parts each of which directly and surely performs its function in the operation of the entire apparatus.
One specific form of apparatus embodying the invention is shown in the accompanying drawing which is a transverse vertical section of an atomizer embodying the present invention.
The device may consist of a base member l which preferably will have a fiat bottom and may be of any suitable plain or ornamental shape. The member l is hollow and forms the tank to contain the liquid to be dispersed or atomized. As shown a thimble 2 may be fastened in a hole at the top of the tank l. Any suitable opening for supplying liquid to the tank may be employed or liquid may be fed through the thimble 2. Preferably threaded in the thimble 2 is a pipe 3 which extends upwardly more or less vertically therefrom. Carried by the pipe 3 is a bellows member 4 extending upwardly from the thimble 2 but terminating below the upper end of the pipe 3. At its upper end the pipe 3 is provided with a transversely arranged rod 5 on which rests a ball 6. The ball 6 is smaller in diameter than the inside of the pipe 3 but so large that it may not pass between the rod 5 and the inner wall of the pipe 3. Above the ball 5 is inserted, preferably threaded, a thimble or nipple 'l having a preferably centrally disposed passage 8 therethrough considerably smaller in diameter than the pipe 3 and provided at its lower end with a more or less concave seat 9. The ball 6 will preferably be made of very light material so that slight air pressure from below will lift it against the seat 9 and close the channel 8 against outward passage of air. Within the portion of the pipe 3 enclosed by the bellows 4 is a transverse bame plate o which extends entirely across the pipe 3 and is solid so as to divide the pipe 3 into two portions, an upper portion and a lower portion, in such a way that there is substantially no leakage of air past the bame plate ID between the two portions of the tube or pipe 3. Mounte'd within the pipe 3 and preferably centrally 'disposed is a smaller tube Il which passes through the battle plate o which may act as a brace or holding means therefor. The tube ll extends beyond the lower' end of the pipe3 to near the bottom of the liquid chamber l. Thus normally the lower end of the tube H is buried in the liquid in the tank. The tube ll rises within the pipe 3 to a point above the upper end of the belloWs 4 but below the cross-bar 5 where it is turned or bent sideways preferably with a double bend, passing through the wall of the tube 3 and to the atmosphere through the ornamental or bracing member !2 applied to the pipe 3 above the bellows 4. The outer end of the liquid tube I l is open to the atmosphere. Where the tube ll passes through the wall of the pipe 3 there is a small opening l3 communicating with the pipe 3 above the baflie plate IO. Below the bafiie plate ID is an opening |4 in the pipe 3 allowing communication between the inside of the pipe 3 and the inside of the bellows 4. Above the baflie plate o is an opening l5 allowing communication between the inside of the pipe 3 above the bale plate !0 and the inside of the bellows 4.
With the parts in the condition illustrated in the drawing the inside of the bellows 4 is in communication with the atmosphere through the openings 8 and l5. The space in the liquid tank above the liquid is in communication with the inside of the bellows 4 through the opening l4 and the open lower end of the pipe 3. Compression of the bellows 4 causes suflicient air pressure to lift the ball 6 and close the air channel 8. The air under pressure from the bellows is also forced through the opening |4 and the open end of the pipe 3 to the surface of the liquid in the tank I. This may tend to cause liquid to enter and rise in the pipe l I. The air under pressure in the bellows 4 communicates through the opening |5 with the upper end of the pipe 3 and above the baffle plate I 0 and may be forced through the opening 3 into and through the outlet of the liquid tube ll atomizing and forcing outward liquid from the device.
Preferably the hole l4 will be somewhat smaller than the hole !5 so that as the bellows member 4 is collapsed or compressed a larger portion of the contained air will tend to come out through the portion of the pipe 3 above the bale plate H thus tending to supply air under suicient pressure through the opening I 3 to cause proper operation of the apparatus.
As the bellows 4 is released the air pressure on the surface of the liquid in the tenk I may be relieved while the ball 6 may fall against the rod and open the channel 8 for the admission of air under atmospheric pressure to the bellows 4 as it returns to its normal condition to thus be in position for another atomizing operation.
The specific details of the parts shown are not essential to the apparatus nor are any specific sizes, forms, shapes, etc., essential since the invention may be embodied in numerous types of apparatus.
