S'IBAINER FOR VACUUM GASOLENE SYSTEMS.
Specification of Letters Patent.
Patented an. 27, 1920.-
Application filed March 81, 1919.- Serial No. 288,425.
to rid gasolene or other combustible fluids from sediment during passage from they 7 supply tank to the carbureter of an internal combustion engine. It is well-known that frequently dirt, sand, or other sediment accumulates in the supply tanks, and is carried to the carbureters ofmotors, thereby clogging small apertures or passageways and interfering with the proper functioning of the parts of the carbureter. This is also a frequent occurrence in systems where vacuum is used to move the gasolene from a supply tank to the carbureter. In the vacuum tanks of wellknown makes, a screen or strainer is employed to intercept the dirt,
sand, orother sediment but despite the presence of such screens, or strainers, the foreign matter escapes through them or clogs them so as to interfere with the proper functioning of the parts. One reason for this is that the' foreign matter is impinged downwardly upon the screen or strainer in the passage of the gasolene therethrough, With the use of the present invention these diificulties'are. overcome, the foreign solid matter being completely separated from the gasolene'. The invention provides for the interposition, between the supply tank andvacuum tank, of a strainer, supported by the vacuum tank and through which the solid foreign matter is precipitated into a receptacle upon the movement of the column of fluid in a downward direction, before the fluid passes up through a screen before flowing to the vacuum tank. The invention further consists in the several novel features hereinafter fully set' forth and claimed.
The invention is clearly illustrated in the accompanying drawing, in which,-
"Figure 1 is a central longitudinal section through a strainer embodying a simple form of the present invention, and showing the same applied to a vacuum tank of wellknown construction;
and a resi- Strainers for Vacuum" character 5, designates a vacuum Fig. 2 is a plan of the device removed from the tank;
Fig. 3 is a view, looking from below, of
the device, part1 I broken away, and the re-' ceptacle remove ,and Fig. 4 is .a face view of a. certain locking ring.
Referring to said drawing,
wellknown construction, the interior of which is connected to the manifold (not shown) of the internal combustion engine with which it is used, by a-pipe leading from the fitting 6. As is wellknown, a partial vacuum is created in the vacuum tank, in an intermittent manner, whereby ,a *practically constant supply of gasolene is maintained in the reference tank .of l
the vacuum tank. Ordinarily, the vacuum tank is connected to the gasolene supply tank by a pipe 7 leading directly from the vacuum tank to the supply tank, but-with the' use ofthe present invention said pipe is disconnected from the vacuum tank and the present device is interposed. between the vacuum tank and pipe. The usual feedpipe (not shown) runs from the vacuum tank to the carbureter.
In the embodiment of the invention illus trated, the device comprises a tubular supplprting stem 8, having a passageway 9 for fluid, which discharges into the receiving end of the vacuum tank. In the illustrated form of connection between the device and vacuum tank,'the tubular stem 8, terminates in a loop 10 through which is passed-the threaded stem of a set-screw, or bolt 11, which fastens the device to the head of the vacuum tank,,whereby the device is supportedby he tank. The setscrew or bolt has an annular groove 12 which registers with the discharge end of the passageway 9, and from said groove leads an L shaped passage 13, which runsto the interior of-the, vacuum tank, thereby esta,b' l1shing communication between the passageway 9, and vacuum tank. Gaskets 14, are interposed between the head of the setscrew or bolt 11 and loop 10 and between the loop and head of the vacuum tank to prevent leakage at these places.
The other end of the tubular stem 8 is provided with a hollow enlargement or head 15 for rcceiving'the screen, dirtreceptacle and connecting device for the supply pipe; As
shown, head 15' is in the form of an,
} centrally pass opening port 19. The interior of the head .a so communicates with the supply pipe 7, which may have boss 18 by a setscrew or bolt 21, similar to the setscrew 11, and having an L shaped ipe and with its interior of the h is exact form of connection between the supply pipe and head is immaterial, as any suitable fitting may be employed for this purpose. The discharge end of the said Set screw, bolt or fitting 21, terminates below the level of the port 19 and the screen 22 is the port- 19. Said screen 1s constructed of l very fine material and. has a very fine mesh to exclude particles that mightpossibly be carried 'in suspension in the fluid passing to port 19. Preferably the screen is annular in form and surrounds the stem 21 of of thescreen may be soldered to the wall 17 of the head 15. It is preferred to make the screen concavo convex in cross section as shown, although this is not essential to the inventionbroadly considered. The screen covers the port 19, and effectively ssageway 9, opens to the interior' of t e head through an upwardly,
a loop 20 secured to the 13, communicating with the supegly of construction is preventspassage therethrough of any solid foreign matter.
' Below the screen is a receptacle 23 for catching and retaining "any dirt, sand, or
other sediment the strainer. constructed of gla$ or other transparent material whereby the contents thereof 15 con- Which may find its way to 'stantly visible; .it is of cup-like formation" I Y and has a flange-24 upon its upper end,
which is clamped between an annular shoulder 25 formed in the head 15, and a lockmg ring 26' threaded in the lower end' of,
I the flange 16. ,Gaskets or packing rings'27 are interposed between the receptacle flange ring from 24' and shoulder 25 and locking .26 to make a tight joint. at this place. onvenlently notches 28 are formed in the lower e of the o g ri g 26 to enable a spanner wrench of suitable form to be used in screwing up or unscrewing the locking the head. ,Said gaskets or packing'rings 27 also protect the glass re'cepta-' cle from injury by reason ofthe prexure thereon caused by the locking ring.
In operation a partial vacuum is created the vacuum tank 5 by the motor in the usual and well known manner, and this causes an inflow of gasolene to the tank from which it flows to the carbureter. Before entering the vacuum tank it passes through I and secured in place by the locking located above said discharge end and below -to point'out all of the invention the setscrew 21. For convenience the edges h the strainer where its 'passa is indicated by the arrows. It is to be 0 served that it menters the rece tacle 23 in azdownward dithrough the screen 22, practically none of the solid foreign matter lodges on the screen, but falls to the bottom of the receptacle. The receptacle may be readily de-' tached by unscrewing the ocking ring 26, and the sediment thereu on may be removed from the receptacleami the latter replaced rmg.
More or less variation of the exact details Y is arranged to be supported directly on the vacuum tank in open communication with the interior thereof, and the other end-of which-is arranged for connection with the usual solene su ply pipe for the vacuum tank, ttin'gs having downwardly'dischar ing gasolene assages therein for removab y Sald receptacle is preferably (i securingsai hollow stem to said vacuum tank and supplypipe, the discharge port of the asolene passage of the fitting for the supp yipe being located below the inlet port to t e passage in the hollow stem, a gasthe interior thereof, .and the other end of which is formed with a hollow head having an inlet port to the: passage in the hollow stem, arranged for connection with the usual gasolene supply pipe for the vacuum tank, fittings, having downwardly discharging gasolene passages therein, for removably securing said hollow stem to said vacuum tank and'supply pipe, the discharge port of the gasolene passage of the fitting for the supply pipe being located below the inlet port to the passage in the hollow stem, a gasolene receptacle removably supported by the hollow head of said hollow stem, between the discharge port of the supply pipe and inlet port to the passage of the hollow stem, and a screen interposed between the discharge port of said fitting for the supply pipe and inlet port to the hollow stem.
