Beit known that l, FREDERICK L. SHELOR, a citizen of theUnited States, residing at Salem, in the county of Roanoke and State of Virginia,'liave invented new and useful of which the iol- `vice or tra-p adapted especially for use with the filling apparatus shown in my copendin applications, Serial Nos. 75,7 97 and 75,798, filed February 21916, respectively. It is the object of the-invention to provide a device adapted to be disposed in an air suction conduit such as is employed in a filling apparatus disclosed in either of said between a pump and a filling ingoperable to catch any liquid sucked with the air into the air conduit, whereby to collect said liquid, and prevent it reaching the pump.
l nother object o3: the invention is a provision of the device of the nature indicated .embodying a pair of overflow jars or traps and novel means whereby they are alternately illed and discharged, to provide for a continuous operation without any appreciable interruption .A further object of the invention is the provisie-n of novel means in a device of the character indicated, Jr'or alternately connecting the jars or traps with the pump and nozzle or other device, and to provideinovel cumula'ted liquid from the 'the discharge of the acjars The present device is so constructed and means for effecting i operable that by manipulating a single knob means -for stopping the when the ,liquid levely or controllin member, the connections with the jars can die reversed, to change the filling of the jars, whereby the empty one is lfilled and the filled one is automatically discharged. The invention also includes suction of air from the jar being filled,
7 rises to a predetermined point, thereby stopping the flow of liquid into the jar, and also preventing the iow of. liquid into the pipe which leads to tliepump.
-With the foregoing anu other objects in view whichwill appear as proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter deseribedand claimed,it being understood that Specification of Letters ratent.
" 6 are seatable.
the description l' Patented omav se., aait.
changes in the precise invention herein disclosed can be made Within the scope of what is claimed with. out departing from the spirit of the inven tion. v
The invention is illustrated in the 'accompanying drawings, wherein i Figure 1 is an elevation of .the device, ortions being 'shown in section. -i Fig. 2 is a horizontal section taken on the line 2--2 of Fig. l.
Fig. 3 is an enlarged sectional detail o one of the three-way valves..
Fig. 4: is an enlarged sectional detail of one of the air vent valves.
In carrying out the inventioma pair ef inverted jars or trap vessels l are employed, `the same being preferably constructed o glass, so as to' render their contents visible,-\ and closures or .caps 2 threadedly receive the lower open ends of said jars i.' The caps i?, close said jars, and said ars are air tight.
To accomplish the drainage or discharge of liquid from the jars l, Adepending elbows 3 are attached to the caps 2 andprovide lower'outlets for the jars, and pipe sections 4 are attached to the lower ends of .the elbows 3, and said ends oil the elbows pre vide valve seats 5 lagainst which bali valves A pin 7 is preferably car-y ried by each pipe section i near the valve seat 5, to holdthe respective valve (i adjacent its seat. The adjacent ends yoi the pipe sections 4. are connected by a T-coupling" with the pipe section'ii which can yentend downwardly to a `tank. or reservoir, which maybe the tank vfrom whichthe liquid is pumped, which will be apparent by reference to said applications. The valves 6 seat' toward the jars, in order that the suction or partial vacuum within the jars will tend toA seat thevalves 6 and hold them seated,
A, 'vertical air vent tubev 10 extends through each cap 2 and terminates adjacent the upper end of the respective jar l, and the tube 10 is provided adjacent its lower protruding end with an aperture li. A sleeve valve l2 is rotatable upon the lower protruding end of each tube l0 to cover :the aperture 11 under certain conditions, and said sleeve valve 12 .has an aperture i3 adapted to be brought into and ont of regis` tration with the aperture 11. The valves i2 are supported bynuts or other supporting elements-1e engaged upon the lower ends of embodiment of the 'JEF the tubes 10, and said valves 12 have outstanding arms 15 connected by a link or rod 16, whereby the valves are operated simultaneously, but the valves are moved to open and closed positions alternately. Thus, when the link 16 is moved ytoward the left, as seen in Fig. 1, the right hand valve 12 will be moved to bring its aperture 13 into register with 'the corresponding aperture 11, while the left hand valve 12 (not shown in Fig. 1) will be moved to closed position, and vice versa.
A lso extending through the cap 2 of each jar are vertical outfiow and' inflow tubes 18 and 17, respectively, which have their upper ends terminating adjacent the upper end of the jar. The upper ends of said tubes 17 andr 18 are provided with the respective overhanging hoods 19 and 20 projecting away from one another, and providing the respective lateral side openings or apertures 21 and 22 directed toward opposite sides of the jar. Thus, any liquid flowing into the jar from the tube 18 through the aperture 22 will be directed away from the tube 17 toward that side wall of the jar 1 remote from said tube 17, and the air will be drawn from the jar 1 from that side wall therebf oppo-I site the tube 18. This eliminates the liability o the liquid splashing from the tube 18 to the `tube 17, and being sucked down the tube 17. In order to shut oit the How of air from each jar into the tube 17 when the level of the liquid rises above a certain point, or near the upper ends of the tubes, a suitable fioat 23 is mounted for vertical sliding movement upon the tube 17 adjacent the upper end thereof, and is normally seated upon a shoulder 24 with which said tube is. provided. Saijd float 23 carries or is carriedby an upstanding sleeve valve 25 slidable upon the tube 17, and normally disposed below theaperture 21, but when the float 23 is raised, the sleeve valve 25-will move upwardly and close the aperture 21, whereby to cut off the flow of air into the tube 17 l from the ar 1, and to therefore vstop the further suction of air und liquid into the jar from the tube 18.
The alternate iilling of the jars 1 is accomplished by means of a pair of three-Way valves 26 and .27, which are superposed as illustrated, and which are practically of duplicate construction. Each of the three-way valver embodies a body 28 `in which a tapered plug 29 is rotatable,`and a nut or other retaining element 30 is engaged upon the lower smaller end of the plug and bears upwardly against the body to hold the plug seated snugly within the body. The body 2 8 of the upper valve 26 is provided with diametrically opposite ports 31 connected by pipe sections 32 with the lower protruding ends of the tubes 17, and the plug 29 of the `taneously with the plugs 29, since an arm 44 upper valve 26 has a passage 33 adapted to be brought alternately into registration with the ports 31 and pipe sections Connected to the body 28 of the upper valve 26 is an air suction pipe 34 leading to a pump (not shown). The body 28 of the lower valve 27 is provided ,with diametrically opposite ports 35 connected by pipe sections 36 with the lower protruding ends of the tubes 18. The plug 29 of the lower valve 27 has'a passage 37 adapted to be brought alternately into register with the ports 35 and pipe seetions 36, and an air suction pipe 38 is connected to the lower'body 28 and is adapted to be connected to a filling nozzle or other equivalent device. f The upper larger end of. the lower plug 29 hasl an4 upstanding noncircular stud 39 received by a non-circular recess 40 in the lower end of the upper plug 29, whereby both plugs 29 rotate simultaneously, and the upper end of the upper plu 29 has a knurled finger piece or knob 41 or conveniently rotating said plugs from one position to another. It is preferable to provide the upper plug 29 withA a pin .42 working in a slot 43 of the upper body 28 to limit the movement of the plugs properly. lVhen the plugs 29 are rotated in one direction, the passage 33 establishes communication between theA ipe section 32 at one 95 side and the pipe 34, and the passage 37 establishes communication with the pipe sec- `tion 36 at the same side and the pipe 38, and
when said plugs are reversed, they establish communication between the pipe 34 and the other pipe'section 32 and between the pipe 38 and theother pipe section 36, whereby 'the pipes .34 and 38 are alternatelyA connected with'thejars.
The air vent valves 12 are operated simulis engagedupon the-stud or lug 39 and projects toward the link 16, and said link is providedwith .a loopy or eye 45 receiving the end of the arm 44, whereby operated when the plugs 29 are.
In operation, supposing that the plugs 29 are rotated so that the pipes 34 and 38 are brought into communication with the respective tubes 17 and 18 of theleft hand 3.1.5:`

Any liquid which is within the right'hand jar 1 will flow downwardly through the respective elbow 3 and will unseat the vailve 6 so that the liquid can flow idown the pipe 9 to the tank or reservoir, air being admitted 125 into the right hand jar 1 through the respective air vent tube 10. The air vent tube 10 of the left hand jar 1, however, is closed, and when the pump is in operation the air suction will `Ltend fremthe pipe 34 leading 13"() the valves 12 are 110 l from the pump hand jar 1, and
