NOV. 28, s E. WH|TE AUTOMATIC FEED CONTROL FOR LIQUlDS Filed Feb. 9. 1931 INVENTOR Patented Nov. 28, 1933 AU'roMA'rie FEED "coN'rRoLroa 'LIQUIEDS YSanford E. WhitaSantaMonica, Calif. YApplication February 9,1931. Serial No. y514,482,
rclaimsicl.1311+103) My invention relates to automatic feed con- A trol'for liquids, and is particularly adapted for the automatic control of an oil supply from a Y yreserve tank cr reservoir to the crank case of an iautomobile or other mechanism where itis necessary to maintain a certain oil level if the best resultsare to be secured. v
vThe invention herein presented is a vfurtherV improvement over my invention as shown and' lfdescribed in my pending applicationSerial No. 510,574, and among the salient objects of this present invention are to simplify and make more economical and practical in construction and v arrangement my invention as shown in the applilfcation above referred to; to provide anautomatic feedv control of the character referred to without a float; and to provide an improved means'for retarding the opening of the valve `permitting the inflow of lfresh voil into a crank ZO--case or other chamber until the oil on the walls of the crank case or chamber has settled down into the case to Vestablish the true Yoil level.
In order to further explain my invention, I have illustrated an improved form or embodiment thereon of the accompanying sheet of drawing, which I will now describe.v f
Figure 1 is averticalsectional view through a mechanism embodying lmy improved automaticY feed control, showing the vreserve tank inelevation; and
Figure 2 is a fragmentary, sectional view the reservoir with parts moved.y
Referring more in detail to the drawing, 5 designates a reservoir which can be connected .35 with 'the main crank case or other chamber (not shown) in such a way as to maintain the same general liquid level, said connection being through a pipe 6, or other structure in which both chambers will have the same liquid level, indicated by the line L. A reserve tank or reservoir for oil or liquid supply is designated '7, and is connected by means of a pipe 8 with the reservoirl 5, said pipe passing through a stufng box 9, and having its lower end terminating at the normal level of liquid.
The reserve tank is also provided with a visible' gauge 10, and the pipe 8 is provided with a valve 11, for shutting ofi` the ilow of oil whendesired for any reason. Pivotally mounted in the reservoir 5, is a lever 12, carrying intermediate its ing in a cylindrical extension 17 in the top ofthe reservoir 5, said cylindrical extension being conf` nected by means-ofV a pipe 18 with the mainold of a motor, or other means for creating a suc tion through said` pipe 18, and Within said cyv having a flaringlower end, which may beprot5 vided to more ee'ctively closethe cylindrical extension 17, when said'V member lis raised. Said j cylindrical member 16 is shownprovided witha p rod or stem 16',which extends through a stuingA boX 19, up into a dash pot 20, and 'is providedf70 within said dashpot 20 with a piston-like mem'- ber 21, which fits lclosely within said dash pot and functions vto retard the downward movement ofthe cylindrical member-16, whenthe suction through the pipe 18is stopped. Thedash pot 2G 75 is provided with a small orifice 22, to permit the slow inflow of air. The'dash pot, if Ymade as a Y separate member and rconnected throughv themedium of the stung box 19, may be connected 21'. l The connecting link 15, from the lever 12, is
provided'with a slot 15', at its'lower end, and the 85 connection with the end of the lever 12 is by means of a pin 12' through said slot, for the purpose of providing a lost motion. A spring 24 is attached to the lower end of said link 15, and to the oor of the reservoir, as at 25. mally draws downwardly on said link and cyf lindrical member to return it when thesuction is cut 01T, and as the dash pot permits it to move downwardly slowly. A second coiled spring 26 is attachedto the side of the reservoir, as at 2'?, and 95 is extended to the middle of the lever 12, and attached thereto, as at 28, to operate as a quick moving means for said lever as it crosses center in either direction. `It will be seen-that the link y 15 can move the distance .represented by the .-100 length of the slot 15 without moving the valve 13.
In order to prevent the reserve liquid in the tank '7 from running downinto the reservoir 5 when the valve 13 is moved from the vend of the pipe 8, said tank 7 is made air tight and the feed 1055' therefrom can only be made as air finds its way up through the pipe 8, and as'soon as the oil vor liquid in the reservoir 5 has reached the end of said pipe 8, it closes it and the further now 4of liquid is stopped.
This nor- Y efficient means for automatically and slowly feeding oil'from a reserve to the chamber in which it is being used for the purpose of maintaining a normal level in said chamber, and while I have illustrated a preferred form or embodiment of said invention, I do not limit it to the being used. Y
