STRAINER FOR GASOLENE TANKS.

APPLICATION FILED APR.11, 1910.

Patented Mar. 11, 1913.

To all whom it may concern:

EDMUND HANS, 0F MINNEABOLIS, MINNESOTA.

STRAINER FOB- GASOLENE-TANKS.

Specification of Letters Patent.

Be it known that I, EDM ND E. HANS, of

Minneapolis, Hennepin county, Minnesota,

have invented certain new and useful Improvements in Strainers for Gasolene: Tanks, of which the following is a specification. l

' The object of my invention is to provide a device in connection with a gasolene tankfor straining purposes to separate dirt and foreign material therefrom before the oil enters the pipe leading to the engine cylinder. Screens and strainers of various kinds have heretofore been provided for this purpose, but they are all more or less objectionable as the foreign material will collect on and fill the meshes of the screen itself, necessitating frequent attention to prevent serious interruption in the flow of the oil.

My invention has for its prima ry object, the separation of the dirt and foreign materlal from the gasolene largely by precipitation without danger of the foreign material collecting and clogging the strainer or screen itself.

My invention consists generally in a shield pipe or guard arranged to inclose'the inlet to the suction. pipe and having an open end projecting into the cup whereto the suction pipe is attached. I

In the accompanying drawings, forming a part ofthis specification, Figure 1 is a side elevation of a gasolene tank embodying my invention,.Fig. 2 is a vertical sectional view of the same,

In the drawing, 2 represents a tank having an opening 3 in its bottom and 4 a cup secured to the .bottom of, the tank around said opening and having a drain cock 5 through which the accumulation in the bottom of the cup may be drawn off. A suction pipe 6 has-a connection .7 with the cup 4 through the upper walls thereof. The inlet to the'suction pipe 6 is preferably'located near the opening?) in *the bottom of the tank and to shield or guard this inlet opening, and to prevent dirt and foreign material frombeing drawn into the suction pipe, .I provide a pipe 8 having one end in- 'closing the inlet to the suction pipe and brazed or otherwise secured to the wall of the .cup 4 and preferably inclined to the horizontal as indicated in Fig. 2 or 'ar-' ranged at an ,angle to the axis of the pipe 6, if located as in saidfigure. The foreign material in the gasolene' therefore settling on the rounded inclined surface of the pipe 8, will tend to slide off and be directed" thereby into the bottom of the cup. The pipe 8 has an open end and is preferably of greater diameter than the diameter of the inlet opening to the pipe 6, so that the suction in said pipe 6 will not cause a strong draft at the inlet of the pipe 8 but rather will allow the oil to move so slowlythat the force of gravity will overcome the tend-' ency of the particles of dirt to enter the pipe 8 and will cause themto settle to the bottom of the cup 4;. Within the pipe 8, I provide

screens

9 and 10 through which the gasolene passes; I have shown two of these screens but a greater or less number maybe provided as preferred and as the surfaces Patented Mar. 11,1913. Application filed April 1-1, 1910. Serial No.'5 5 4,891.

of the screens are inclined with respect to the axis of the suction pipe, the foreign material coming in cont-act therewithwillhave a tendency to slide off and drop to the bottom of the cup. The-screens are shownas located, one near the middle of the pipe 8 and the other at its open end. but they may be arranged in any other suit-able position inthe shield pipe. i V Beneath the pipe 8, pan 11 secured by any suitable means in the cup and having a. hopper bottom with a discharge opening 12 spaced from the bottom of the cup. This pan will prevent the foreign material accumulating in the bottom of I prefer to provide a J the cup from being stirred up or shaken by i the motion of the car and drawn up to a point where they might 'tend' to lodge on the outer screen on the shield pipe. This shield i pipe may be made of any suitable length,and

its diameter with'respect t'o'the diameter of the suction pipe may be varied to suitrthe, conditionsand to adaptit forthe enginewith;

which it is used.

In various ways, the details-of construetion herein maybe modified without; depart 1 ing' from theepirit ofmy invention:

I. claimas my invention:

1,.v Thejcombinatiomwv'ith a. gasolene tank, of a cup. inclosing an opening in the-bottom of saidtank and secured thereto and having adrain cock, a suction pipe communicating with 'said'cup through the walls thereofand near the opening in the bottomo'f said tank,

a- 'shield' pipe inclosing the inlet opening to. said suction pipe and having an open inner end and inclined Y the horizontal, and

ing' said opening and projecting into said cup and having imperforate walls and an open inner end, said open end lying in a plane at an angle to the transverse axis oi said cup, said imperforate walls deflecting the ascending and descending-particles of sediment, a screen disposed in said opening, said cup having a wall below said guard operating to deflect the sediment toward the center of the cup away from the open end of said guard.v

. 3. The combination, with a tank having an opening in its bottom, of a cup having an,

open top adapted to register with said opening and secured to said tank, said cup having a suction discharge opening in its side walls, a tube open at each end secured to the inner wall of said cup and encircling said suction opening, said tube being downwardly inclined and projecting across said cup,. the open end of said tube extending across the cup to a point near the opposite wall thereof from said suction opening a screen provided in the open end of said tu e,

a second screen provided in said tube be- 4:. The combination, with a tank havingan opening in its lower wall, of a cup surrounding said opening, said cup having a discharge opening in its side walls, a guard surrounding said opening and projecting into said cup and having imperforate walls and an open inner end, said open end lying in a plane at an angle to the transverse axis of said cup, said imperforate walls operating to deflect the ascending and descending particles of sediment, a screen disposed in the open inner end of said guard, and means arranged below said guard for deflecting the sediment toward the center of said cup. In witness whereof, I have hereunto set my hand this 2nd day of April 1910.
