Specification of Letters Patent. j

PatentedMay 4, 1920.

Application leld August 2, 1919. Serial No. 314,839.

To all whom t may concern.'

Be it known that I HARRY JACKSON, a citizen of the United States, and a resident of the city of New York borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

This invention relates to a pump, and aims to provide a device of this nature which shall be peculiarly adaptable to the pumping of fluid, such as oil, water and gasolene, although the same may be used for any fluids.

A primaryobject of my invention is to construct a pump which shall incorporate absolute simplicity in construction andinterchangeabilityof parts, together with efciency of operatlon.

Another object of the invention is the provision of a single vane which will present two separate pistons, so that :all parts such f as springs, etc., may be eliminated.

A further provision of my improved pump is the construction of means associated with the ends'of such vane which are adapted to act in the capacity of both valves and by means of which a tight seal is formed within the pump, and which means will be capable of taking up practically all of the wear incident tothe operation of my pump.

A still further object of my invention is the provision of a. bearing associated with my pump, which bearing will eiliciently lubricate the moving parts without imparting the lubricant to the fluid acted uponby the pump.

Another object of the invention is the provision of a pump which may be run clockwise or anticlockwise,`so that it will be impossible for the most unskilled laborer to apply the same improperly, whereby a great expense to the user will be saved, as it quite often occurs that either the driving motor,

or the pump in its associated connection,A p

must be entirely reversed.

A nal object of my invention is the general arrangement and construction of parts whereby any back pressure within the pump will be eliminated.

Reference is had,` to the accompanying sheets of drawings which illustrate'onepractical example of my invention, and in which Figure 1 is a front view of my assembled pump g 'tor 12 there is Fig. 2 is a section taken along lline 2-2,

F i 1' Fig.7 3 is a sectional view through the power shaft and bearing associated therewith taken along line 3-3 of-Fig. 1;

Fig. 4 is a sectional side view showing the relative parts in the operative position and taken' along line 4 4 of Fig. 1;

Fig. 5 is an elevational v1ew of the rotor of my'pump with itsassociated parts; and

Fig-6 is an elevational view of one of the bearings.

In these various views like reference numerals designate similar parts, and the reference numeral 1 indicates the casing of my pump, which includes a circular bandlike center portion and the conventional diskshaped side walls tightly bolted to said center portion. The side Walls, in the usual manner, are provided with openings through` which shafts 2 project. The side walls adjacent the aforementioned openings extend outwardly so as to form a tubular portion 3, which is screw-threaded, as indicated at 4. Engaging the screw threads 4 is a col'- lar nut 5, the upper end or collar portion of which engages a liange 6 formed upon the bearing which I associate vwith my pump. This bearing includes a cylindrical art 7 provided with a reduced portion 8 ormed with openings 9, for apurpose hereinafter specified.

The bearing is inserted in the tubular portion 30 indicated in Fig. 2, and the collar of the nut 5 engages the ange 6, and upon such nut being rotated it will be seen that the bearing will be forced inwardly along its shaft 2 and against a packing 10 positioned at its inner end.

Thecasing 1,in the usual manner, is provided with inlet and outlet openings 11, and eccentrically mounted within such casing is a rotor 12 the outer face of which clears the inner face 'of the casing at its lowermost oint 13 by any convenient spacing which shall be sufficient to prevent wear of either the rotor or the casing due to the movement of the former with respect to the, latter.

Extending transversely through the roformed a slot 14 1n which is slidably mounted a vane 15 which is formed with a reduced neck portion 16 adjacent its outer edge and a beaded end portion 17.

The shoe 18 is provided with a groove 19 formed with an enlarged base into which the beaded end 17 of the vane 15 is slid, so that the shoes 18, although firmly secured to the ends of the vane 15, are capable of a rocking motion with respect thereto, it being also noted that recesses are provided in the rotor` in which said shoes may seat. The longitudinal edges' of the shoes 18 are pro-v vided with extending portions 20, for a purpose hereinafter more fully set forth.

It will now be noted, upon reference to Flg. 4, that even although the openingwithin the casing, with which one of the pipes 11 communicates, is fully covered, it will be seen that the opposite opening is slightly uncovered, so that it is impossible during any part of the cycle of revolution ofthe rotor for the shoes to completey close both the inlet and outlet pipes. his arrangement of parts, as will readily be seen, eliminates all possibility of back pressure within the pump and, consequently, the pump, although operating far more eiciently, requires less driving energy than pumps heretofore constructed.

-F rom the above it may beseen that I have constructed a pump which may be oiled through openings 21 by virtue of the oil being distributed evenly over the exterior face of the bearing, which oil will subsequently be fedthrough openings 9 on to the shafts 2; but by the arrangement of the reduced portion 8 of the bearing and the packing 10 it will be impossible for the oil, due to suction 0r capillary attraction, to move into the casing 2 and then be transmitted to the fluid operated upon by the pump.

It will further be appreciated that I have constructed a pump which will operate as efficiently 'as a multibladed pump, but-yet in which there is incorporated only la single vane, which single vane is positively acted upon so that no danger of the device coming out of adjustment, breakage of parts, etc., exists.

It will be seen that, by virtue of the shoes 18, I provide an absolutely dependable seal, and by means of their connection with the vane 15, it will be noted that this seal be- .comes tighter the greater the pressure against which the pump must operate. Further, the extending portions 20 'of the shoes- 18 take up the wear imparted to the shoes, which are virtually the only parts where any appreciable wear occurs, so that y the most trying ofservice conditions, by prothe shoes 18 do not'have to be renewed until l the extensions 20 have worn flush with the longitudinal edges of the shoes 18.v Ob- `viously, these shoes might be constructed to last a 4great length of time, even under jecting the extensions 20 to any desired extent.

It will be appreciated what a tremendous advantage m construction offers overA pumps hereto ore constructed in that back pressure is absolutely eliminated by Virtue of the fact that the vane 15 and its associated shoes or valves 18 are so tight that a simultaneous closing of both openings within the pump casing by means of such shoes is impossible.

` Obviously, any number of modifications l let openings, and -a vane slidably associated with such rotor, the inlet and outlet openvin s being so positioned with respect to the axis of revolution of the rotor as to partially close one of such openings and completely close thev oppositeI opening simultaneously.

-3. A pump, including a rotor mounted within a casing provided with inlet and` outlet openings, and means associated with such pump whereby to partially close one of such openings and `completely close the opposite opening simultaneously.

4. A pump, including a rotor mounted within a casing provided with inlet and outlet openings, a vane slidably associated with such rotor, and shoes rockingly mounted upon the outer ends ofsuch vane and being adapted to coact with the inlet and outlet openings of such casing in such a manner as to partially close one of such openings and completely close the opposite opening simultaneousl y HARRY JxoKsoN,
