PUMPING MEANS Filed April 13, 1927 2 Sheecs-Sheet 2 Patented Dec. 5, `1933 UNETED STATES PATENT OFFICE 12 Claims.

My invention relates to pumping means generally and particularly to pumping means which are automatically controlled to retard or to start or to stop a pump means to keep or to maintain a certain quantity of iiuid in a receptacle or to supply a certain quantity of fluid according to certain needs.

The main object of my invention is to provide a pumping means which is simple and inexpensive in structure, which is easily installed, which is economical and efficient in operation, which is automatic in operation so that the same requires very little or no attention, which can be operated either by mechanical means or by a fluidic means or by a combination of both of them, and which can be operated either by an easily available sourceof power or by a source or power which is otherwise lost or of no further use for other purposes or after it has performed its original function. Other objects will appear, or become apparent or obvious, or will suggest themselves, during the description of the particular apparatuses shown in the accompanying drawings,

In many instances it is quite desirable to keep liquid at a certain height or level in a receptacle or tank or can from which the liquid is taken either regularly or intermittently or periodically and either in an even orin an uneven flow, It 30, is also quite desirable that the means, which keeps this level constant, be operated or operable at minimum cost and that such means operate as near automatically as possible so that very little or no attention is required for them.

In auto-vehicles, or boats, or other apparatus having a power plant, or individual power' plants, io instance, a receptacle may supply gasolene to a carburetor, or a receptacle may supply water to a boiler or to a radiator, or a receptacle may sup- 40 ply air to a burner or to another element to retain the same under a certain pressure or for other purposes, or a receptacle may supply other iiuid for other purposes. In such cases as well as in similar ones, it is quite desirable that the quantity oi duid taken from the receptacle be replaced in the receptacle in the same ratio or proportion in which it is taken from it. It is also quite desirable that the means which so replaces the iiuid be as near automatic in operation as is possible so that the entire means needs very little or no attention and operates at a minimum cost.

In auto-vehicles as well as in many other instances, there are various sources of power which have served their intended purpose and are going (Cl. 10S-23) to waste or are lost or perform no further function. In the exhaust of gasolene or gas or steam or similar engines, the flow of the intake in gasolene or gas engines, the flow of air from a cooling fan, the moving of the vehicle or of parts .B0 thereof, as well as many other sources of power associated directly or indirectly with a power plant or other apparatus having features as described above, many sources of power are easily available for pumping purposes and the use of these sources of power does not detract anything from or in any manner diminish or decrease the eiiiciency of the apparatus or part from which these sources are derived since their original and intended usefulness has been attained and accomplished and whatever power is still residing therein-may just as well be utilized for pumping purposes and is used for such `purposes in the present invention and thereby operate pumping means without materially increasing the cost of operation of the original apparatus and in many instances practically without cost for the operation thereof.

In order to illustrate my invention, I have shown in the accompanying drawings, by way of example, two devices each having pump means and the necessary or convenient means associated with or associable with the pump means, and one individual pump which can be used in connection with various elements of various apparatus or devices; all of the devices shown embody features of my invention. I am aware, however, that my invention can be embodied in other devices or in other apparatuses or in other combinations than those shown.

In the accompanying drawings:-

Fig. 6 is a section taken in a vertical plane similar to Fig, 5 but at right angles thereto and shows the relations between the operating shaft and the crank means and the connecting rod and the plunger and the Valve means and the supporting means more clearly.

' Fig. 7 is a general perspective view of a device embodying features of ymy invention and shows a rotary pump jointed or movable on the cover of a receptacle; the pump cylinder being above the receptacle and the entire pump means being moved toward and away from an abutment and device rbore 11 for the pump plunger 12 and the bore 13 to form a receptacle within the receptacle A to retain a certain quantity of the fluid handled by the pump in the receptacle or ybore 13 and thereby keep the pump primed at all times even when the fluid substance has all been taken out of the receptacle A. The boss 14 is cast onto the bottom of the'receptacle A for purposes appearing presently and the boss 15 is cast onto the side of the receptacle A to receive the pipe or tube 16 which conveys fluid from the receptacle A to the carburetor B. In the present instance, the fluid in the receptacle A is assumed to be gasoline and the carburetor B is assumed to be adapted to effect the proper mixing or other function to adapt the gasoline to a useful function.

The bore 11 has the valve seat 17 at the bottom thereof and the bore 13 has the valve seat 18 at the bottom thereof; both valve seats being in communication with each other through the opening or hole or passage way 19. The ball 20 rests on the valve seat 17 and the ball 21 rests on the valve seat 18; 4both balls forming valves and being free to move 01T of the seat thereof and being held onto the seat thereof by their own weight due to gravity.

The hole 22 is in communication with the hole 19 and with the pipe 23 which leads to the i supply tank C and is threaded into the boss 14.

The cover D, a casting in the present instance, closes the top of the receptacle A and has the ears 24 extending upwardly therefrom and also has the abutment 25 and the hole 26 for purposes appearing presently.

The pump housing E, a. casting in the present instance, has the ears 27 extending between the ears 24; each of the ears 24 and 27 forming a pair and having the pinv 28 extending through it. This arrangementy forms a swivel or pivot joint so that the housing can be swiveled on the cover for purposes appearing presently.

The pump operating shaft F has the bearing portion 29 journaled in the boss 3) of the housing the eccentric or crank portion 31 for the con necting rod 32, the bearing portion 33 journaled in the boss 34 of the housing E, and the portion 35 to which the wheel G is fastened.

The wheel G, a casting in the present instance, has the `rim Scand the vanes 37 similar to the vanes in a fan or in a windmill and the hub 38 to support the wheel on the portion 35 of the shaft li.

The plunger 12 extends into the bore 11 and the upper end thereof has the slot 40. The connecting rod 32 has the eye 41 fitting to the eccentric pcrtion 31 of the shaft F and the eye 42 extending into the slot 4). The pin 43 extends through the plunger 12 and through the eye 42 to form a jointed connection between the connecting rod 32 and the plunger 39.

The housing E, the shaft F and the wheel G thereon, and the connecting rod 32 forni an articulate pump operating means with one end pivotally fixed and theA other end free to-move or swivel on this pivot.

The shaft 44, journaled in any suitable manner, has the belt wheel 45 with the belt 46 running thereon and also has the fan wheel H fastened thereon. Ths structure represents a power means. Y

The float I has the arm 47 extending to and secured to the arm 48 extending from the housing E. vThis structure represents a pumping control means.

As to the operation of this particular device; starting the description with the elements in the positions shown in Figs. 1, 2 and 3:-

When the shaft 44 is rotating, either rotated by the belt 46 or moving the same, the fan 37 rotates and creates an air current moving or flowing toward the wheel G and through the spaces between the vanes thereof and thereby tends to rotate the same in the manner of a windmill and thereby rotates the shaft F which operates the pump means.

The now moving belt 46 is now in contact with the outer circumferential surface of the wheel G and thereby also tends to rotate the shaft F by frictional contact therewith.

The rotation of the shaft F operates the pump- :Ing mechanism in the usual manner and draws gasolene from the tank C through the pipe 23 and discharges it into the receptacle A. through the hole 13. This discharge of gasolene into the #D receptacle causes the level of the gasolene to rise in the receptacle and thereby creates a condition which raises the float I and thereby swivels the housing E on the pivot pins 28 and thereby moves the wheel G away from the belt 46 and out of Contact therewith and thereby stops the rotation of `the shaft F by the belt and thereby stops the operation of the pump mechanism oy this source of power. Y

When the air current operates or rotates the wheel G, either independently of the belt 46 or in conjunction therewith, after the wheel G is the operation of the wheel and consequently of the pump mechanism by power created by the air current.

While the carburetor B is taking a certain quantity of gasolene from the receptacle A through the pipe 16 to maintain the level of the gasclene in the receptacle at a certain height, the pump mechanism is operated constantly. When the demand for gasolene by the carburetor decreases, the level of the gasolene in the receptacle risesv and moves the float upwardly and thereby decreases the operation of the pump mechanism or stops the same entirely as explained above. When the demand for gasolene by the carburetor'increases above normal, the level of the gasolene in the receptacle falls and moves the iloat downwardly and thereby releases the wheel G from the brake to permit the air current to rotate the wheel G and thereby start the operation of the pump mechanism. A further fall of the level of the gasolene in the receptacle moves the wheel G- iurther and contacts the same on the belt and thereby operates the pump mechanism in a more positive manner. Consequently, the operation of the pump mechanism is automatic and is controlled by the requirement or demand of gasolene by the carburetor and the pumping activity is controlled by conditions created by pumped substance and can vary from and to full and aero activity and activities in betwen full and aero activities.

Referring now particularly to the device shown in Figs. 4, 5 and 6 of the drawings:-

The device shown here is an individual unit pump attachable to, or associable with, various devices and is operable by a suitable air current or by mechanical means described above or by other suitable means.

The cylinder K has the bore 49 with the valve seat 50 and the hole 5i in the bottom thereof and also has the boss 52 externally threaded to receive the nut 53 and internally threaded to receive the pipe 54 which leads to a supply tank. The nut 53 clamps the ilange 55 of the cylinder against the member 56 which may constitute the bottom of Va receptacle or other means for supporting the cylinder, The cylinder also has the bore 57 with the valve 58 in the bottom thereof. The hole 59 establishes communication between the bore 49 and the bore 57. The ball 60 normally rests on the seat 50 due to gravity and the ball 61 normally rests on the seat 58 due to gravity. Ears 62 are provided on the upper end of the cylinder.

The housing L has the ears 63 adjacent to the ears 62 and forming pairs therewith with the pivot pins 64 extending through the pairs of ears and also has the bosses 65 and 66 on the upper end thereof.

The shaft M has the bearing portion 67 journaled in the boss 65 and the eccentric portion 68 and the bearing portion 69 journaled in the boss 66 and the brake portion 70 and the portion 71 to which the hub 72 of the wheel N is secured.

The wheel N has the friction element 73 and the vanes 74 similar to a windmill so that the wheel can be operated either by an air current or by mechanical means as described in connectionr with the device shown in Figs. l, 2 and 3.

The abutment 75 extends from one of 'the ears 62 and is xed and has the oblong hole 76 through it; each end of this hole is curved to the same radius as the brake portion 70 so that this brake portion engages these curved ends and forms a brake similar to the brake eiect produced between the wheel G and the abutment 25 when the housing L is swiveled on the pins 64.

The connecting rod O has the boss 77 over the eccentric portion 68 and the boss 78 extending into the slot 79 in the plunger 80 and pivot-ally held 'therein by the pin 81 extending through the plunger and through the boss 78. The plunger rits slidably and operates in the bore 49.

In this instance, the housing L, the rod O, the shaft M, and the wheel H form an articulate pump operating means pivoted at one end and free to move at the other end in a manner and .for purposes as the device shown in Fig. l.

The operation of this device is similar to the operation of the device described above; the wheel N is movable toward and away from a driving means; in this instance, the housing swivels on the cylinder whereas the housing first described swivels on the cover of the receptacle.

Referring now particularly to the device shown in Fig. 7 of the drawings- In this device, the rotary pump P is movable bodily on the cover Q which closes the receptacle R and is moved toward and away from the wheel S and to and from the abutment 82 by means of the bell crank arm 83 extending from the float T and pivoted on the pin 84 extending through the ears 85 on the cover Q and having the connecting rod 85 pivoted to the ears 87 which extend upward from the arm 83 and thereby constitutes an articulate pump operating means. The rod 85 is threaded into the pump so that the pump moves laterally as the float rises and falls in the receptacle. When the pump is so moved by the iioat, the wheel 88 is moved toward and awa* from the wheel 89 as well as toward and away from the abutment 82. The wheel 89 may be operated by any suitable means and the fan wheel 9G may be mounted on the same shaft as the wheel 89 or on another shaft.

Either one of the devices shown and described can be operated by a source of power which is easily available and which may have had no further utility; the air current used may conveniently be the air current produced by the fan of an auto-vehicle and used after the same has accomplished its originaliy intended oiice; a belt which drives the ian of an auto-vehicle or another device can easily be used to operate the pump means with practically no cost for power; in fact the .i

belt is brought into better contact with the pulley thereof by the use thereof as a power source for pumping purposes as herein set forth.

Each of the pumping means shown and described has a means for automatically supplying iiuid as needed at a minimum cost.

I am aware that my invention can be applied to apparatus and devices other than those shown and described andthat changes may be made and can be made in thestructure as well as in the arrangement of the elements shown and described within the scope of the appended claims; therefore, without limiting myself to the precise application of invention as shown and described nor to the precise structure and arrangements of elements as shown and described.
