LESTER S. KEILHO'LTZ, OF DAYTON, OHIO, ASSIGNOR T0 DELGO-LIGHT COMPANY, OF
DAYTON, OHIO, A CORPORATION OF DELAWARE. '7
ENGINE.
Application filed October 3, 1923. Serial No. 666,256.
To all whom it may concern:
Be it known that I, LESTER S. KE'ILHoL'rz, a citizen of the United States of America, residing at Dayton, county of Montgomery, State of Ohio, have invented certain new and useful Improvements in Engines, of which the following is a full, clear, and exact description.
The present invention relates to supply tanks from which a liquid is pumped to a higher level.
It is an object of the invention to maintain substantially constant, as regards the pumping operation, the pressure head due to liquid in the tank, although the level of liquid may vary within certain limits by means of apparatus which is more simple and reliable than heretofore.
The form of invention shown herein constitutes an improvement of apparatus shown in the patent to T. Midgley, No. 1,424,369, issued August 1, 1922, which patent discloses a fuel system for an internal combustion engine including a fuel supply tank having features mentioned in the foregoing. In said patented apparatus it is necessary to provide an airtight joint between the filler opening cover and the tank in order that the apparatus will operate successfully. The present invention requires that the cover of the filler opening be closed but does not require an airtight joint.
Other and further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred embodiment of one form of the present invention is clearly shown.
In the drawings Fig. l is a fragmentary sectional view of a fuel tank embodying the present invention; and
Fig. 2 is a fragmentary plan view of the tank.
In the drawings, 20 is a liquid supply tank having a top wall 21 and a bottom wall 22. The top wall is tapped to receive a bushing 23 which cooperates with a nut 24 to connect pipes 25 and 26 for connecting a pump with the tank near the bottom wall 22 thereof. The pump may be an internal combustion engine which pumps fuel from the tank 20 for combustion in the engine. The top wall 21 is apertured and provided with upwardly opening.
extending flange 27 and downwardly extending tubular flange or apron 28. F lan ges27 and 28 constitute a tubular member extending through the top wall 21 of the tank 20 an] terminating near the bottom wall 22 to provide a filler passage 29.
The top wall 21 is provided with anupwardly extending boss 32 upon which is pivotly mounted the fuel opening cover 33 having an air vent 34. The cover 33 is latched in position by a bale 35 which is pivoted to cars 35 provided on wall 21. (Jover33 is provided with an arm 36 which is pivoted to link 37. The top wall 21 is tapped to receive member 40 having a vertical passage 41 in communication with the horizontal passage 42. Passage 42 emerges into passage 43 at a valve seat 44 which is adapted to receive valve 45 connected to link 37. The link 37 projects through nut 46 screw threaded upon member 40. The connection between the cover 33 and the valve 45 is such that the valve 45 will be closed upon its seat 44 when the cover 33 closes the filler opening, and the valve 45 is moved away from. the seat44when cover 33 is tilted back from the opening. In order to allow for variations in manufacture a spring 47 is interposed between the nut 46 and valve 45 to maintain the valve 45 upon its seat 44 when the cover 33 closes the filler The pivotal connections between valve 45 and cover 33 may be made loose enough to permit seating of valve 45 by spring 47.
The operation of the tank is as follows:
The cover 33 is swung on its pivot to permit the pouring of fuel through the Chit-I111 ber 29 and to open the valve 45. Fuel entering the chamber 29 will pass into chamber 30 and the air contained within the chamber 30 will be forced by the fuel out of the tank through the passages 41 and 42. After the tank is filled the cover 33 is closed over the flange 27 and the valve 45 will be moved into engagement with seat 44. Assume that the chambers 29 and 30 are filled to the line AA. The engine or other liquid pump being started, liquid will be sucked up through the pipes 24 and 22. The level of the fuel in chamber 29 will quickly drop from the level AA to the level BB at the lower end of said chamber. Level BB may be termed the true hydrostatic level of the tank. It is from this level that the pump low the line BB in chamber 29, causing cing-.-
culation of air bubbles around the bottom edge of flange 28 up. through the fuel-in.
chamber 30 to the space above the line AA. Asrfnelis pumped from tan-k 20.,the level will. gradually. descend, the fuel removed beingpdisplaced. by ,air, entering vent 34L and bubbling. around the flange28.
It is. apparent that the. pressure head on pipe line 25, 26 willzremain constant-for a variation of; liquid :level; in tank-2Q between level of.- the. top wall 21 and level .1313. Therefore the effect von the. pumping, appa ratus willibe constant. This apparatus can be used. advantageously in fuel supply-systems for internal. "combustion, engines, Whfllfl: in it isidesirable. that; the fuel mixture proport-ionsshould not be, affected by variations infuel; level; in a supply. tank. fr0m -whicl.1 the engine pumps fueLdirect to the carburee tor-1.:w It 5is=tQ- b 'l nderst-ood however, i that the present invention {is not limited to, use, with engines, ,1 as L its availability for other uses is app rent."
While the. form of mechanism herein shown and described constitutes. a preferred embodiment of oneform of invention,it' is to be 7 understood that; other forms might be adoptedpand various jchanges andalterations madein the shape, size, and, proportion of the element therein without departing from the spirit and scope of the invention.
What is, claimed is as. follows:
