Application filed Gctober 25, 1918. Serial No. 259,668.

To all whom it may concern:

Be it known that I, EnNns'r O. CART- wnrerrr, a citizen of the United States, resioing at Springfield, in the county of Clark md State of Ohio, have invented a new and improved Portable Pumping Apparatus, of which the following is a specification. 1

This invention relates to an apparatus aoapted to be used for elevating and transporting liquids mixed with solids or sediment, the properties of which make it impracticable to handle them directly through the pump, which app? "atus, in its complete makeup includes a motor driven vehicie, a iquid carrying tank mounted thereon and adapted to be dumped, a pump for taking liquid from the tank and returning it, under pressure, to the tank, means to operate the pump by power from the motor vehicle and an ejector through which the liquid taken by the pump from the tank must pass from the pump back into the tank.

prime objects of this i vention are: To provide 'an improved efficient portaole pumping apparatus of the general character stated, in which the ral eleents that constitute the complete mechanism are so designed and cooperatively-so combined whereby the construction of such type of portable pumping ap aratus is of a simple and economical nature.

Second. To provide a new and novel construction of parts that are so located, relatively to each other, that the complete mechan m or apparatus is encon ss d in a comp I lv small limit of sp ce upon the motor vehicle frame and the tank without the use of troublesome and unsightly overluuigiug and upwardly projected parts.

Third. To provide an improved means for suspen ing the circulation of the liquid throi the pump, from and to thetank, in order that the pump may be utilized, will, for either normal elevating or pressure purposes v. th the intake from outsidesou" than the tank, or for direct pr ire purpose with the intake from the tan r. lVith these and other objects in view of which will hereinafter 1 car, my presout invention embod s the features of construction and combina ion of parts to be fully exp. ed in the following description, spezilicall pointed out in the appended 7 being claims and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a motor vehicle with my improved pumping apparatus applied thereto, the pump, the ejector and the-tank being shown in their relative positions, when operating.

Fig. 2 is a view similar to Fig. 1, the parts shown in the relative operative position, when the tank is being dumped.

Fig. 3 is a horizontal section of a portion of the tank, and illustrates, in plan view, the discharge pipe to the rear of the tank, the pump intake at the front end of the tank, the overflow and the filter connection hereinafter specifically referred to.

Fig. 4 is a side elevation, partly in section, of the ejector and the stop or gate valve that cooperates therewith.

Fig. 5 is a detail view of the nipple connection for the upper end of the ejector.

Fig. 6 is detail sectional elevation of the parts that constitute the detachable oint in the pump intake piping and the connection provided for the intake, when it is desired to use the pump for normal elevating purposes.

Figs. 7 and 8 detail views hereinafter soecifically referred to.

in carrying out my invention, I use a tank 1 of any suitable construction and which includes a tail gate 1 that is pivotally mounted on the side members 2-2 of the motor vehicle frame, the gate being held closed by clamps 53 3 designates a hoist, a hydraulic jack of well known construction, and 4: denotes a pump also of a well known construction, which pump is located on the motor vehicle frame between the front end of the tank and the back of the drivers seat.

As a specific construction of the tank, the motor vehicle, the pump and the hoisting jack, per se, constitute no part of my in vention, further detail description thereof is deemed unnecessary.

5, 6, 7, S and 9 designate threaded flanges mounted around openings in two sides of the tank, at the front end thereof, and 10 designates a pipe that is threaded into the flange 5 and from which flange the said pipe extends rearwardly within the tank to a point in close proximity to the tail gate.

At the rear end, the pipe 10 is supported in aranchor bracket 11 secured to the inner threads into the flange 9 on the outside of the tank and the said connection 12 receives one end of a section or" hose 13 that is normally supported upon brackets 1414 along the outside of the tank on a line higher up on the tank than the flange 9.

At its free end, the hose 13 has a coupling 13 adapted to be attached to a hydrant or other water supply (not shown).

A strainer 15 and a stop 16 are serially connected to the flange 7 and the said cock 16 is provided with a lever 17 that has a pull rod or control 18 which extends upwardly and outside of the tank for being conveniently manipulated by the driver while on the vehicle.

19 indicates a coupling pipe, one end of which threads into the flange 8 and whose other end threads into an elbow 19, the dependent or lower end of which is threaded to receive a flanged tapered nipple 20, as is best shown in Fig. 6, from which it will be noticed that in fitting the parts, the nipple 20 detachably seats against a gasket 21 that is held to its place by a retaining ring 22, in a recess 22 in a specially designed flanged T coupling 23, which is coupled up with the intake of the pump, see Fig. 3.

The recess 22, in the coupling 23, merges with an annularly beveled seat against which the gasket 21 is bent back, when the nipple 20 is seated in the coupling, as indicated by dotted lines on Fig. 6.

The T coupling 23 has a threaded opening 24 in which is threaded a nipple 25 that is dapted to receive the coupling of a suction hose (not shown).

Normally the nipple 25 is held closed by .hose cap 26, as shown. r

The flangefi on the front end ofthe tank receives one end of a pipe 27'whose other end threads into a specially designed elbow (see l ig. 8) and in a recess formed in the. base of the said elbow, a gasket 29 is held in place by retaining ring 30, as shown.

i Vhen the tank is at the normal or down position, shown in Fig. 1, the elbow 28 seats onto a tapered. nipple 21 that is adjustably inserted into the upper end of the ejector 32, the details of which are best shown in Fig. 4. V l r V in fitting the parts into operative connection, the nipple 31 is packed up to the necessary point of contact with the gasket 29 by means of packing rings 33 and it is held to its place by a set screw 34 that threads through the upper end of the ejector, see Fig. 5. v

The ejector 32 contains two channels or passages 35 and 38, oneofwhich 35 is a straight way passage that originates at the lower end of threaded opening 36 and terminates at its top end in the seat for the nipple 31.

37 designates a nipple that screws into the wall of the ejector intersects the constrict,

ed orifice 40 and connects with a threaded sleeve 42 that is normally held closed by a cap 43.

44 designates a stop or gate valve and the said valve is slidably adjustable in the 41 having the opening 41. 1

The plug valve 44 includes a threaded stem .44 which terminates in a head for receiving a suitable key 45 for which provision is made on the cap 43' for the convenient holding of the key ready for use, as shown in Fig. 4.

The threaded stem 44 engages an internally threaded passage 42 in the sleeve 42, it being apparent from Fig. 4 that by removing the cap 43 convenient access is had to the key receiving end ofthe stem 44 for turning such stem to feed the plug 44 to the closed position, shown in the said Fig. 4, whereby to cut off the passage 38 that communicates, through the chamber 39, with the pump or for drawing it backward into the tubular neck 40 when a clearness is desired between the delivery from the pump and the constricted orifice 40 that joins with the ejector passage 35.

An outlet opening 46 connects the chamber 39 with a terminal 47 that is adapted to receive the coupling of a hose (not shown). The terminal4? is closed by a hose, cap

A pressure gage 49 is optionally mounted onrthe chamber 39, as shown in Figs. 1, 2 and 3. V

The laterally projected flanged portion of the ejector 32 bolts to a flange 50 on the delivery end 4 of the pump 4, and the flanged portion of the '5' coupling 23 bolts to the intake face 51 of the said pump, as is clearly shown in Fig. 1.

designate sertional cover plates which are held downon top of the tank by winged bolt clamps 53-53, see Figs. 1 and 2, as hereinafter further explained.

Petore proceeding with the'detailed description of the operation of the apparatus neck 7 liereinbefore explained and as shown in the drawings, 3 functions of the said apparatus should be here stated, namely;

First. For the evacuation of cesspools, sumps, basins or depressions or excavations in. which the character of the contents is such that they should not pass through the pump without partial separation from the solids contained in them;

Second. The pumping of liquids directly by means of the pump and delivering them either to the tank for hauling, or a distant point by piping;

Third. F or purposes of spraying liquids from the tank or delivering thesame, under pressure, at a distant point.

Referring now to the operation of the apparatus, the first function or method of its use Jest explained as follows:

Hose 13 is removed from its holding brackets 14-14 and its free end connected to a source of water pressure, and through it the tank is supplied with suflicient water to cover the strainer 15. The hose 13 is then disconnected from the water supply and permitted to hang rem its connection (see arrow a; on Fig. 1) to act as an overflow channel for the tank.

The stop cock 16 is now opened by means of the pull. control 18, acting through the lever 17 when the water Within the tank passes through the piping 19 and the coupling 23, to the pump, which latter is thus primed for operation.

Upon application of power to the pump, water is forced through the constricted orifice 4) of the ejector 32, forming a ct which creates a partial vacuum in the straightway channel or passage 35, causes the water to pass up througn the nipple 31, the elbow 2-8 and the pipe connection :27, into the delivery pipe within the tank, from whence it is discharged at the rear end of the tank.

Now, if the nipple 87 be connected to any cesspool, sump, basin or other depression which collects sediment or accumulations that recuire periodically to be removed, the liquid and contaminations will be drawn up see dotted lines and arrow 2 on Fig. 1) through the ejector passage 35 and the pipe and leposited at the rear of the tank where the sediment and solids precipitate fore.

The overflow hose 13 conveys to any outside point of waste, the partially clarified li uid that collects within the tank beyond the level of the hose connection to the tank.

The operation just explained is continued until the tank is desirably loaded wit. precipitations, after which the pump stopped, hose connection 13 restored upon the brackets 14, the stop cook 16 closed, the lift pipe from the cesspool is disconnected from the nipple 37, after which the apparatus is transported to a desired point for the dumping of its contents.

In order to facilitate the dumping operation and to minimize adjustment that mi ght be required upon restoring the, tank to its normal position, the detachable asketed J. o 1 1 Joints in the T coupling 20 and in tne eioow 28, hereinbefore referred to, have been provided so that, when the front end of the tank is elevated for dumping, as indicated in Fig. 2, the joinings mentioned will scga rate at the gasket 21 in the T coupling 2 and at the nipple 31 on the elbow '28 and when the tank is restored (swung down) to the normal position, the two joints mentioned will automatically close.

In eztpiaining the second fnnctioi orally stated, operation of the parts is as follows:

Stop cock 16 and the hose cap 26 is removed and the place of the latter in the nipple is taken by any suitable hose connected with any desired source of s pply.

The cap 43 (see Fig. 4) is removed, the key 45 is used to return the plug valve 44 to the closed position for stopping off the jet orifice 40.

Cap 43 is then restored to its place on the plug 42.

Hose cap 48 is removed from the terminal 47 and its place is taken by any su able hose connection wherewith, by starting the pump, the liquid pumped may be oeposited either in the tank or at any other desired point.

By reversing the changes enumerated for this last stated function, it is obvious ii at the apparatus is restored for use accordii. to the first stated operation.

For the third stated function, or use, the stop cook 16 is open and the hose cap is in its place closing nipple 25, the plug valve 44 being at either the open or closed positionopen if it be desired to agitate the liquid in the tank, closed if only pressure at terminal 47 is desiredand through any suitable connection with the terminal 47, upon applying power to the pump, liquio in the tank may be disposed at any desired point.

In an apparatus of this character, it is desirable to provide the tank with a cover to avoid splashing of the contents, when in transit carrying liquids and also to avoid unsightly effects on both apparatus and surmovable in order that the tank may be loaded from the top for use, at will, for carrying masses other than liquids and to have the removed cover disposed upon the tank so as to be available at all times to be quickly restored to their functional location on the tank.

It is also a further desirability, that to facilitate transportation upon travelways, likely to be much used by an apparatus 01 the character stated, that the ejector and its necessary means of connection with the places to be evacuated, add to the machine the fewest number of projecting or overhanging parts beyond the normal limits of space necessary for the passage of the vehicle upon which the apparatus is mounted.

To satisfy the desirability for a cover for the tank, I have provided the plates 52, before referred to, and these are detachably placed crosswise of the top of the tank 1 and they are held to their position by the clamp members 53.

The plates 52 are slotted centerway oi"? each end to clear studs of clamping screws 53and to render said plates removable at will.

Crosswise of the motor vehicle frame is .mounted a supporting bar stand the said bar is provided at each end with an upwardly extending stud 54 onto which are received the slotted edges of the cover plates 52, when the latter are taken from the top of the tank, the said bar 54- constituting a convenient means for carrying the cover plates at all times on the apparatus.

Clamp devices 55 are provided for curely holding the plates in position when assembled on the cross bar 54, see 2.

To fulfil the desirability for compacting I have so designed the ejector 32 and correlated it with the other elements of the apparatus that the desired ends are attained.
