CHECK vALvE.
Application med January 15, 1924'. seriati'ro. 686,373.
To all` lwko/ml it may concern.'
v ABe it known that I, HAROLD CON lonars, a citizen of the United States, residing at Kendallville, in the county of Noble andv State of Indiana, have invented new and useful Improvements in Check Valves, of
which the following-is a specification.
This' invention relates to improvements in radiators for internal combustionr motors,
the general object of the invention being to provide means for preventing wasting of the water through the overflow pipe, while preventing any pressure from accumulating in the radiator. f l This invention also consists in certain other features of construction and in the combination and arrangement of the Several parts, to be hereinafter fully described', il-
lustratedin the accompanying drawing and` ure 2. Figure 4 is alongitudinal sectional view i 85 through the device shown in Fi re 1.
Figure 5 is a view similar to igure 2 but showing the-valve' seat member used as a valve. I f Figure 6 is avsection 4on hne 6-6 of Fig- As shownLin Fi res and 4 I provide Aa tube 2'which is slipped over the upper end ofthe loverflow pipe and which has its' u p-I r end threaded to receive the lower part ofthe housing 3. If desired, the uplper end of the overiow pipe vitself may be t readed .to i -receivethis housing as shown in Figures 2 and 5. A cage 4 is arranged in the housing with its anged upper-.end eng ging the tog part .ofthe housmo, and a spring 5 andvba seat 6 are arranged 'in vsaid cage. A threaded cap 7 closes the upper end of the hous-v Figure 3 is a-)section von line 3-3 of Figing and thisl cap is formed with a ball seat 8 for receiving the ball valve 9 which is normally pressed upon the seat 8 by the s It will thus be seen that the over owpipeis`normally closed so that water cannot esl cape therethrough, but as soon as any'pressure occurs in the radiator due to theI expansion of the water by heat or the formation of steam in the radiator, the ball v9 is forcedi. downwardly against the'slight pressure of the spring 5 so that the pressure is removed from the radiator. As soon as the pressure is relieved, the valve will close and prevent e5 i e l the escape of any more water. v I prefer to make the ball seat 6 with 'the cone-shaped lower part 10 so that by turning this seat over it can be used in place of the ball valve 9, as shown in Figure 5. l
The spring will then engage the flat part of this member to hold it against theseat on the cap. This invention will save water by preventing -it from escaping down the overflow pipe when the car is going down a steep grade or when the car comes to a Sudden stop which causes the water to rush to the top of/the radiator.' This device will also prevent the rapid evaporationof alcohol or other -anti-freezmg solutions by preventing 8 0 the escape of the vapors through the over- 'flow pipe. This invention is es ecially valuable in desert countries an other dry places. It is also useful in ,mountainous districts where much water is lost by the vei lfxicle traveling down steep grades. i l By use ,of the cage if the spring shouldbreak, the ballcannot drop down and close the overiow pipe which might causev the rai diator to burst. The ball seat 6 permits the 90.
ball to have free movement so that'it will make a perfect seat on the capand this seat 6, can be turned over and used as' a valve in place of the ball. TheA spring tension'ca'n ybe adjusted by'placing shims 12 betweenthe 95l I cage and the screw capas shown in Figure 5.
Itis thought fromthe foregoing description that the advantages and novel features of'my invention will be readily apparent.'
I desire rit to be understood thatv I may make changesin the construction' and the' combination and arrangement ofthe several parts, provided `that suchchanges fall vwith- 1n the'scope ofthe appended claim. ff,
Having described the invention, I claim A check valve comprlsmg a housing adapted to be connected' witlrthe upper end of a pipe,
a screw cap on the housing having 5 an opening therein, a ball valve closing the openmg a cage 1n thehousing, a spring carthe spring and engagingthe ball va1ve,.said seat having a conical lower part which is arranged to take the place of the vball valve 10 when desired. j
ln'testimony whereof affix myjsignature.
