2 Claims.

My invention relates in general to receiving and. transrerrmg devices and more particularly to devices adapted to receive the fluid removed from a fluid system and to transfer the removed fluid 5 either back into the said system or into any other place of disposal.

An object of my invention is the provision of a receptacle adapted to receive the fluid removed from a fluid system, such for example, as from the fluid system of a motor vehicle.

Another object of my invention is the provision of a transfer pump adapted to transfer thefluid contained in my fluid receptacle either back into the fluid system of the motor vohicle or into any l5other place of disposal.

A further object of my invention is the provision of a receptacle having a deck adapted to receive the fluid from a fluid system, such as from a motor vehicle, and todirect the fluid -..through a screen into the receptacle.

Another object of my invention is to provide for so constructing the receptacle and the deck thereof that the fluid drained from a fluid system will not splash upon the floor or other sur ,L ace while the fluid is being drained therefrom.

A still further object of my invention is the provision of a receptacle that can beset up on Another object of my invention is the provision of a pump which allows the fluid contained in the cylinder to flow freely therefrom without a vac-r uum being created in the pump when the pump is 40*held in an elevated and inverted position so as to cause the fluid contained in the cylinder of "the pump to flow by means of gravity therefrom.

Another object of my invention is the provision" of so constructing the receptacle and the pump 45 that the pump may be detachably connected'to the receptacle, in which case a single pump may be used with a relatively large number of receptacles.

A still furtherobject of my invention is the 50- provision of a pump permanently mounted within my receptacle for transferring the fluid contained in the receptacle back into the fluid systern of a motor vehicle or into any other place of disposal.

Figure 10 shows'the manner in which the fluid in-ithe receptacle may bepumped back into the 40 fluid system of the motor vehicle.

Withparticularreference to the drawings, my invention comprises a receptacle l5 and a cooperatively. associated detachable pump I6.

The receptacle l5 maybe constructed of heavy gage; galvanized iron, or other suitable material, equipped with foursets' of casters l1 suitably swiveled to the receptacle I5 so that the receptacle IEmay-be easily'moved about or pushed beneath a motor vehicle by means of the bail handle I8, which is pivotally connected tothe front end of the receptacle l5.' Tlieheight, length and width of the receptacle [5 depends primarily upon the use'to which it is employed. Thus, when the receptacle I5 is used to drain the water or oil from a motor vehicle, being the embodiment of my invention illustrated in the drawings, the receptacle is constructed low enough to be positioned underneath a motor vehicle of any make, even though one or more of the tires may be deflated. Also, the length and width of the receptacle I5 is large enough to catch the water or the oil drained from the drain outlet on a motor vehicle of any make without needlessly shifting the receptacle under the motor vehicle, see Figure 9. This means that when using the receptacle I5 it is only necessary for the operator to push the receptacle I5 under the motor vehicle without taking very much pains, or without considering particularly whether the drain outlet is near the front or rear, or to either side of the engine because, in any event, the receptacle I5 is large enough to accommodate the drain outlets upon any motor vehicles. Often the drain outlet is so located that the water from the cooling system of the motor vehicle will drain on a front axle or upon'the tie-rod, thus splashing the water in all directions, in which case it is impossible to catch all of the water in an ordinary container such as, for example, a small pan or bucket. However, because of the size of my receptacle I5 it is possible to catch all of the water drained from the fluid system of a motor vehicle notwithstanding the fact that the water may drain on the front axle or upon the tie-rod.

an inwardly sloping surface so that the water is caused to run towards the center of the deck I9 and thence flow through an opening 2| into the receptacle I5. The inwardly sloping surface of the deck I9 is such that very little fluid is permitted to splash over the edge of the receptacle I5, except for a very small amount which may splash over in some cases when the stream initially strikes the deck I9 before the deck I9 has a chance to become wet. After the deck I9 be comes wet, and because of the aflinity of the falling stream of fluid to the wet surface of the deck I9, there is no splashing whatsoever and the fluid calmly flows over the deck I9 and through the opening 2| into the receptacle I5.

To prevent the splashing of the fluid over the edge of the receptacle I5, which occurs when the stream initially strikes the deck I9, there is provided a marginal wall 20 which is high enough to prevent the splashing over of the fluid, and still not too high to prevent the receptacle I5 from being pushed under motor vehicles of all types, even though one or more of the tires may be deflated.

The sets of casters I! are soequipped that the .front end of the receptacle I5 is slightly lower than the rear end.' This inclination causes the fluid contained in the receptacle I5 to flow towards the front end of the receptacle I5 into a sump 56 in which the suction end ofthe pump I 5 is positioned, see Figure 6. Accordingly, substantially all of the fluid contained in the receptacle I5 may be removed from the receptacle for the reason that the sump 56'is the lowest point to which the fluid contained in the receptacle I5 may flow; and from' which the pump I6 is able to pump out substantially all of the fluid except for a very small amount which lies below the bottom of the suction end of the pump I6.

' The pump I6 is particularly adaptable to my receptacle I5 for pumping the fluid contained in the receptacle I5 back into the fluid system of the motor vehicle, see Figure 10. The pump I6 is arranged to be detachably connected to the opening 2| of the receptacle I5. To this end the lower end of the cylinder 34 of the pump I6 is provided with a flange 47 which rests upon the peripheral edge of the opening 2|. Beneath the flange 41 are two oppositely disposed engaging lugs 48 which align with the two oppositely disposed notches 49. Therefore, to attach the pump I5 within the opening 2i it is only necessary for the operator to align the two engaging lugs 48 with the two notches 49 and then turn the pump I6 until the pump pulls tight, at which point the pump I6 is rigidly secured in an upright position to the receptacle I5.

The suction valve assembly 38 is located in the lowermost end of the cylinder 34 of the pump I6 and comprises, generally, an annular sleeve 39 having openings 4 I, a suction valve 42 which rests upon the upper surface of the annular sleeve 39, and a valve guide 43 which is suitably connected to the central portion of the annular sleeve 39. The entire suction valve assembly 38 may be held within the end of the pump I6 by means of a pin 49. To limit the amount that the suction valve 42 may be raised from the upper surface of the annular sleeve 39 there is provided on the upper end of the valve guide 43 an enlarged portion, which constitutes a stop for the suction valve 42. Accordingly, when the fluid is drawn into the pump I6 upon the suction stroke of the pump the suction valve 42 is raised and allows the fluid to flow through the openings 4|, and when the suction stroke is terminated the suction valve 42 is constrained to press against the upper surface of the annular sleeve 39 and thus closes the openings 4!, which prevents any of the fluid contained in the cylinder 34 of the pump I6 from flowing back into the sump 56 of the receptacle I5.

The valve assembly for the piston 35 is similar to the suction valve assembly 38, and comprises a piston valve 45 which rests upon the upper surface of the piston 35 for closing the openings 44 which extend through the piston 35. In order to limit the amount that the piston valve 45 may be raised there is provided a pin 46 within the stem 31 of the pump !6. The pin 46, in this manner, constitutes a stop for the upper limit of travel for the piston valve 45. During the suction stroke of the piston 35 the piston valve 45 is constrained against the upper surface of the piston 35, and thus closes the openings 44 which extend through the piston 35, and upon the downward stroke of the piston 35 the piston valve 45 is raised and allows the fluid beneath the piston 35 to flow through the openings 44 in the piston 35 to the cylinder 34 of the pump I6, which is above the piston 35. As illustrated, the piston 35 is provided with two annular grooves 36, which during the pumping operation become filled with the fluid being pumped. In this manner the fluid which is contained between the grooves 35 and the inner walls of the cylinder 34 of the pump It constitutes a good seal, and thus very little fluid, if any, is allowed to leak between the piston 35 and the inner wall of the cylinder 34. I find, in actual operation, that the fluid such as the antifreeze solutions for the radiator attacks leather and rubber, or any other gasket material, and for this reason I have obviated the use of such packing material to provide a seal between the piston 35 and the inner wall of the cylinder 34 of the pump I6. Therefore, my pump I6, as it is constructed solely of metal parts needs no attentioni whatsoever: as would :be theicaseti-f :rub ber, leather, or other packing materialxwere used to provide a seal between the rpistons351andthe' inner wall of the cylinder 34 .of .thepump I Ii.

The upper end of the cylinder 34 -of=the1 pump' I6 is providedwithia pump header .50, which: may be welded or otherwise-suitably connectedto the: cylinder 34. In accordancewith thetgeneral con-1 struction of pumps the header. 50 is provided with: a packing 5I, which is .constrained'topress ina: wardly against the pump. stemv .3I 'by means ofsa packing nut :52: .threadably engaged within :the': header 50. Attached to'thepumpl header 59. is a hose 54 havingza hook .55 attachedztocf the :end thereof. Thehook 55' is particularly'adaptab'le with the new radiatorsrfor'rmotor.rvehicles in which there is a battle plate. positioned. above the tubes of theradiator, in which'case thetupturnedz and extended portion of thehook: 55 is allowed to;

hook under the ledge of theinecklof" the radiator,

to prevent the hose 54.:from beingdetached'from. the radiator duringthe? pumpingaoperation;-

The completeroperation'of myinvention may". be described as follows: Let it be assumed'thateit is necessary to drain the-fluid tfromzthe cooling: system of a motor vehicle, which: occasion may. arise in putting on a hot water heater,:installing a new hose or repairing the radiator for any. other purpose. If the motor vehicle containsan; anti'-: freeze solution it may be drained into':-the-re=: ceptacle I5 until the repairsarermadet and then? pumped back into .the'imotors vehicle after-the repairs are made: To'carry outizthi'soperation" the receptacle 1 5 is pushed beneath themotor .vehicle for catchingithe fluidldrained fromtheixmor-i' tor vehicle, see Figure '9. i After the receptacle I 5 1' is placed beneath the. motorivehiclethe operator; operates the drain" outlet and: allows the water:

to drain into the receptacle 15;". Inforder, to keep the fluid clean there is proVided'in'theJopeningZI of the receptacle I5 a screen: 22 'havinga handle;

23 and engaging lugs'24, which h01dS..fl1e:SCI'eBI1;: 22 within theopening 2 I. In somexcasesithe mo'-'" tor vehicles may be parkedquite:close'ztogethemr or may be parked nearzthe.wallof.the:building,;v

and in these' cases"thezoperatorredges :therres ceptacle I5 in anuupri'ghtimanner between 'thi closely spaced cars; or between :the: caraandi the: wall, and gradually'iworks the bottom end of the receptacle I5 under the motor vehicle as the upper end of the receptacle I5 clears the adjacently placed car or the closely spaced wall. After the fluid is then drained into the receptacle I5 the operator may grasp the bail handle of the receptacle I5 and withdraw the receptacle I5 from beneath the motor vehicle at the same time lifting the front end of the receptacle I5 to clear the adjacent motor vehicles, or the closely spaced wall. Therefore, it is noted that the deck I9 constitutes an enclosure for the receptacle I5 so that the receptacle I5 may be withdrawn from beneath a motor vehicle without any of the fluid surging or spilling on the floor, or other surface beneath the car. When the receptacle I5 is withdrawn from beneath the motor vehicle it may be set up on end out of the way until the fluid is to be pumped back into the fluid system of the motor vehicle, see Figure 2. In this upturned position the bail handle I8 may act as a prop to prevent the receptacle I5 from falling over.

After the repairs are made, or when it is time to transfer the fluid contained in the receptacle I5 back into the fluid system of a motor vehicle the pump I6 is then attached to the receptacle 'l5 andrthe end of the hose. 54 is inserted withinathefluid system of the motor vehicle, seeFi'ga um: 10: Upon the suction stroke of the pump I6 the' fluId is drawn into the cylinder 34 through theiopenings II and past-the suction valve 42. Uponithe downward stroke of the pump "I6 the fluid: contained beneath-the piston 35 is forced through'the openings and past the piston valve 45 into the space above thepiston 35. Upon the. return suction stroke the fluid that is contained' in the pump I6 above the piston 35 is forced: through the'hose 54 into the fluid system of the' motor vehicle, during which suction strokeanother supply of fluid is withdrawn from thereceptacle. I5 intothe suction pump beneath, the 1valve 35. The pumping operation is then continued until all of the fluid is withdrawn from the receptacle I5 leaving only a very small amount withinthe sump 56;

As for the fluid which remains in the pump I6 after all: the fluid is substantially withdrawn from the H sump 56, this fluid may be likewise discharged into" the fluid system of the motor vehicle..: Thismay be done in the following manner. r After the pumping operation is completed the operator disconnects the pump I6 from the receptacle I5 and then elevates the pump I6 at.;the'1.same timegradually tilting the pump so that the. fluid contained in the pump I6 will run,:-by:means-.xof'gravity, into the fluid system offichemotor vehicle. Inasmuch as both the suctionyalve'4'2 and the piston valve 45 are open when'zthe" pumpmlfi is tilted to its inverted positiong'the fluid contained within the pump I6 will freelyt'flow into the fluid system of the motor vehiclelwithout causing any vacuum being created in the.z pump,xwhich vacuum if allowed to exist would tend to retard thefree'flow of the fluid contained in the pump I6 to the cooling system of the: motor vehicle. The operator when elevating and tilting the pump I6 to discharge the fluid containedin the pump I6 to the fluid system: of the'motonvehicle may so elevate and tiltxthe-pump I6 as to cause the rate at which the fluid-.flows-into the fluid system to be rather gradual withoutcausing any of the fluid to run over:the neck of the radiator of the'motor vehicle.-

Therefore, by means of my invention the anti-. freeze solution in motor vehicles may be Withdrawn into my receptacle while making repairs, and then pumped back into the motor vehicle without wasting any of the antifreeze solution.

In some of the service stations which service a great many motor vehicles, there is a necessity for a large number of the receptacles I5, in which case one pump may serve several receptacles. Also, in some cases, it is desirable to close the opening 2I to prevent any evaporation or any accidental spilling of the fluid contained in the receptacle I5 through the opening by accidentally knocking over the'receptacle I 5 when it is set up on one end out of the way. To guard against the wasting of the fluid contained in the receptacle I5 there is provided a lid 3| for the opening 2I, see Figure 8. As illustrated, the lid 3| has a handle 33 and two engaging fingers 32, which securely hold the lid 3I within the opening 2|.

In Figure 5 I show a. modification of my invention in that a pump I Go is mounted within a receptacle I5a, by means of a pump flange 62 bolted or otherwise connected to the front end of the receptacle I5a. As illustrated, the suction end of the pump Ilia is positioned within a sump in an upright manner the sump 63 becomes the lowest point within the receptacle I50, so that I substantially all of the fluid may be withdrawn therefrom by means of the pump l6-a. In both of the receptacles l and IE1: there is provided a drain plug 51 and 58 respectively for draining the fluid from the receptacles.

While I have explained the operation of my invention in connection with principally draining the fluid from the cooling system of a motor vehicle it is to be clearly understood that my invention may likewise be used in connection with withdrawing the oil from the engine, or for withdrawing the fluid from any other fluid system whether or not it is related to a motor vehicle.

Although I have described my invention with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
