PRES SURE REDUC ING MEANS Filed Aug. 27. 1925 Patented @CL 29, 1929 UNTED STATES JOHN C. IPURDIE, OF CHICAGG, ILLINOIS PRESSURE-IREDUCING MEANS Application filed August 27, 1925.
My invention relates to pressure reducing means for use in connection with apparatus for giving therapeutic treatments, and it has for its object the provision of a new and improved form and arrangement of parts by which a spray of oxygen may be controlled with respect to quantity and pressure so as to deliver the desired type of stream against a part to be treated, such stream of oxygen to carry with it preferably also a quantity of water or other liquid for assisting in the healing value.
It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. rlhe preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specifically described. That which I believe to be new and desire to cover by this application is set forth in the claim.
In the drawing,-
Fig. l is a vertical sectional view through my improved pressure reducing mechanism; and
Fig. 2 is an enlarged detail view, being a horizontal section taken at line 2-2 of lFig. l.
Referring to the drawing, 36 indicates a pipe leading from any suitable source of oxygen under pressure, being removably connected with a sleeve or housing 37 by means of a tubular shank 38 and a coupling 39, said shank 38 being formed integrally with said housing.
A valve 40, preferably of the automobile tire type, is secured by means of screw threads in the lower end of the shank 38, with the stem 41 of such valve extending some little distance into the sleeve 37, the arrangement being such that when the stem 4l moves upwardly the passage through the valve is opened. At the lower end of the housing 37, there is a diaphragm 42 held in position by a coupling 43 and a cap 44, suitable spacingl blocks 45 being inserted between the diaphragm 42 and the stem 4l so that upon upward movement of the diaphragm the valve 40 will be opened. Nithin the cap 44, I have provided a spring 46 which presses upwardly upon the bottom face of the diaphragm 40 Serial No. 52,826.
a bearing block 47 being interposed between the spring 46 and the diaphragm. A screw 48 is secured by means of threads in the lower end of the ycap 44 being adapted to move the lower end of the spring 46 upwardly through the medium of a bearing plate 49. The side of the housing 37 communicates with a pipe 50, the outer end of which is connected with a flexible tube 51 leading to any suitable type of atomizer or other delivery apparatus not shown.
By an adjustment of the screw 48, the pressure upon the bottom face 0f the diaphragm 42 by the spring 46 can be controlled for regulating the pressure of oxygen capable of being built up within the housing 37 by the oxygen escaping thereinto through the valve 40. As the pressure within the housing 37 is increased when gas is escaping through the 7alve 40, the diaphragm 42 is moved downwardly by such pressure permitting the valve 40 to be partially closed. This results in a decrease in the amount of gas entering the housing 37, thus reducing the pressure within the housing and permitting` the spring 46 to move the diaphragm upwardly for increasing the extent to which the valve 40 is opened.
By the use of my improved pressure reducing means, I am enabled to operate an atomizer or other aproved delivery apparatus at a pressure of from l to 4G pounds, the pressure at the outlet pipe being indicated by a pressure gauge 52 mounted thereon.
IVhile I prefer to employ the form of mechanism as shown in my drawing and as above described, it is to be understood that I do not limit the invention to such form except so far as the claim may be so limited by the prior art.
I claim:
A pressure reducing means, comprising in combination a sleeve open at one end and having an outlet port at one side, a tubular shank communicating with the sleeve at its other end, a cap opening into the open end of the sleeve and of substantially the same inside diameter, a flexible diaphragm extending across between said sleeve and said cap, means for releasably connecting the sleeve and the cap, bearing members extending substantial- 1y across the cap7 a spring interposed between said bearing members, an adjustable set screw mounted in the end Wall of the cap adapted by Contact With one of said bearing members to press the other bearing member yieldingly against said diaphragm, an outwardly opening Valve detachably mounted in said shank and removable therefrom through said sleeve, and spacing blo-ek means extending substanlo tially across the sleeve between said Valve and said diaphragm adapted upon movement by the spring toward said shank to open said Valve for admitting iuid under pressure through said tubular shank for escape chrough said outlet port.
