SUCTION INTAKE FOR PUMPS APPLICATION FILED JAN. 14. 1920.
III/I unrren eras eaeur eerie,
JAMES B. FISHER, F WAUKESHA, WISCONSIN, A SSIGNOR T0 WAUIKESHA 15101 03, COMPANY, OF WAUKESHA, SCONS IN, A; CORPORATION OF WISCONSIN.-
suc'rron rm'ann ron ruiuns.
inane-lo,
T 0 all whom it may concern Be it known that 1, JAMES B. FISHER, a
citizen of the United States, residing at Waukesha, in the county of l Vaukesha and State of Wisconsin, have invented a certainnew and useful Improvement in Suction Intakes for Pumps, of which the followin is a clear, concise, and exact description, re erence being had to the accompanying drawings, forming a part of this specification.
The present invention relates to pumps and more particularly to improvements in suction boxes and screens for usein connection with lubricating oil pumps for supplying lubricating oil to the bearings of an internal combustion engine.
l have'found that in the use of a screen in connection with the suction intake of a lubric'ating oil pump for use in the crankcases of internal combustion engines, the suction of the pump is often destroyed when the oil level in the crank case is not maintained at a predetermined point, in other words, when the oil level drops below the upper end of the screen. lhis is partly due to the admittance of air to the intake of the pump through the screen, and partly due to foul ing of the screen by the heavy constituents often found in lubricating oils.
Therefore, the primary object of my invention is to provide means on the screen whereby the pump suction, and consequently the operativeness of the pump is maintained until practically the supply of oil in the crank case is exhausted, and while most users of internal combustion engines are apt to neglect to keep the oil at a certain predetermined level, nearly all users will at least replenish the supply of oil in the crank case before complete exhaustion of the supply. Thus my present invention practically insures operation of the pump at all times, it not being required that the oil leyel be kept at a certain predetermined point, it only being necessary that there be a reasonable quantity of oil in the crank case to insure against loss of suction of the pump.
The subject matter of the invention is particularly'designed to meet with the condi tions outlined above and is especially suited for use in connection with lubrication systems for internal combustion engines, but, course, it is not limited to its present adaptation and use, assimilar conchtions may and often do exist in many other cranes Specification of Letters Patent.

Application filed January 14, 1920. Serial No. 351,304.
houses the screen and forms a pocket thereabout in which the oil or other liquid is trapped, so that when suction is applied to the interior of the screen a vacuum will be created within the screen and shield which w llinsure operation of the pump by maintam ng the suction thereof until the oil or liquid evel falls below the lower end of the shield, the shield being of such a length as to practically insure against such an occur- 'rence as the user of the engine will almost invariably replenish the supply of oil before the same reaches such a low level. ll do not limit myself to any particular shape of screen, nor to the exact manner in which the same is supported, but ll shall describe hereinafter a preferred embodiment of the invent1on, this being brought forth in the following specification and the claims appended thereto, taken in connection with the accompanying drawing, in which:
Figure l is a side elevation of the suction screen or my invention, and
Figure 2 is a vertical section of the same.
Referring more particularly to the drawing, 10 designates the lower half of the crank case of an internal combustion engine, the same being provided-with a hand opening 11 in the bottom 12 thereof. The opening 11 is closed by a removable cover l2 secured in position by means of bolts 13 or the like. I
1t designates the casing of a rotary pump Bil for furnishing lubricating oil to the bearice The bracket 18 supports the suction screen and shield of my invention. The screenis designated 19 and is preferably cylindrical in shape, said screen having a plate 20 secured to the upper end thereof and having illitl Qis 1..-baaaaaan 21. The shield is designated 22 and is p Sieferabl cylindrical 1n shape,theside;wa
thereo flaring slightly outwardly as shown and spaced from the screen, the shield terminating as'at 23 at a point above the lower end of the screen and I flipafied from the bottom of the crank casing.
endfwall Q/i'ofthe shield is disposed be- I tween Ethe-i-pIateQOand the bracket 18, and
intake 28 extends from the pump 14 down I through the chamber formed by the screen 19 and. terminates at a point achacent the bottom 21- ofsaid screen. The liquid level. which in the present case is the levelof the lubricating oil in the crank ca'se, is at 29, and it will be apparent thatwithout the use of the shield 22,.as scenes the .liquidlevel drops below the top of the. screen 19 the liquid contained within the screen wouldbe removed by the suction pipe '28 and then the suction pipe would'be- I 'n to draw air, as the-oil would not pass 'fimu'ghfthe meshes ,of the screen rapidly enough tomaintain the suction. However, f .;lwhen the shield is usedit will be apparent "that even though the liquid level does fall within the s 'eld and within the screen, par- "below the top of the'screen as it is shown in the drawin a vacuum is established at ticularly within the latter, which acts to cause the oil to be forced through the screen.
Thus the heavy constituents of theoil are taken care of and the pump will not draw any air until the li uid'level falls below the lower edge of the s 'eld.
' ,While I have shown a specific embodiment aofm inventioniriit will be realized by those fami iar with t .e art that minor changes maybe made therein without materially departing from the spirit, in the invention, for instance, the shield may be made of different shape and lengths and may be made to surround the screen entirely for proteo tive purposes and be provided with the nee 'essary openings near its bottom. Various other changes may be made without departing from the spirit and scope of the invention as claimed.
I claim:
1; In combination, an oil reservoir, a cylindrical screen, means for exposing said screen directly to the oil in said reservoir throughout its entire circumference over the of said reservoir below said screen for storing accumulated sediment.
2. In combination, an oil reservoir, a cylindrical screen, means for exposing said screen directly to the oil in said reservoir throughout its entire circumference over'the lower portion of its length, and means for keeping the entire length of said screen submerged in oil as long as the oil level in said reservoir is above the upper end of the exposed portion.
3. In combination, an oil reservoir, an oil pump spaced-from the bottom thereof, an inverted cup-like shield belowthe bottom of said pump, and an upright cup-shaped screen in said shield projecting beyond the open end thereof.
4. In an intake, a cup-shaped screen opening upwardly, a pocket below said screen for storing sediment, and a cup-shaped shield opening downwardly and-housing the upper portion of said screen.
said screen, said shield terminating above the lower end of said screen to expose the entire lower end of said screen directly to lower portion of its length, means for keep- 5. In an intake, a cylindrical screen, and a cup-shaped shield over the upper end oflip well below the normal oil level in said i reservoir, a screen in said cup extending" below the level of the edge of said cup,.'and
means for withdrawing oil from inside' sa-id a cup shaped screen openmg upwardly, means for f screen. 8. In combination, an-oll reservoir,
withdrawing oil from inside said screen, and
a pocket in the bottom of said; reservoirbe low said screen, said pocket having a removable bottom. v v In witness whereof I hereuntosubscribe my name this 2d day of J anuary, 1920.
