I OIL DISTRIBUTING APPARATUS Filed'March 5, 1945 Patented Apr. 19, 1949 OIL DISTRIBUTING APPARATUS David B. Baker, Riverside, 111., assignor to International Harvester Company, a corporation of New Jersey Application March 5, 1945, Serial No. 581,111 6 Claims. (01. 184- 6) This invention concerns systems for distributing oil in desired small quantities to several points and relates more in particular to a type of apparatus in which the oil is discharged pastweir means into passages leading to the respective points.
Oil distributing apparatus constructed according to the invention is especially useful in the picking units of cotton harvesting machines of the general character disclosed in U. S. Patent No. 2,140,631 to E. A. Johnston. Such units embody a picking spindle carrier rotatable about a vertical axisand having a great number of spindle bearings and spindle driving gears all spaced radially from the carrier axis. These gears and bearings require a lubricant in ample amount because of their rapid and continuous operation,
and although the quantity of lubricant (which thus. far has been oil) required at the various points is small, it should not exceed the required amount to thereby insure the deposit of none on the cotton crop. Cotton splotched with oil is lowered in grade.
A general object of this invention is the provision of an oil distributing system employing a device adapted to distribute small quantities of oil inequal or other predetermined relative amounts and not materially affected in: its accu racy by slight tilting. tossing or vibrations to which it may be subjected while inuse upon a vehicle such as a cotton picking machine.
A more specific object is the provision of an oil distributing device rotatable about an upright axis coaxial with an oil containing pocket therein, togetherwith a plurality of distributing channels and weir means over which the oil flows from the pocket into the channels.
A further objectvis the provision of a deviceposed contiguity with the weir means toresist irregularitiesv occurring in the oil level and thereby contributeto the evennessof the oil feed rate into-the channels.
These andother desirable objects wil1be more readily apparent after reading the ensuing description with reference to the drawings, Where- Fig. 1 is avfragmentary. sectional view taken upon a vertical plane extending diametrically,
through the rotatableistructure of a cotton picking unit embodying a form of the invention; and
Fig. 2 is a fragmentary sectional View taken horizontally upon the line 2-2 of Fig. 1.
The oil distributingdevice is generally designated Ill and is mounted coaxially with a rotatable carrier structure 12 0f the cotton picking unit. This cotton picking unit is of the general character of that disclosed in the aforesaid Patent No. 2,140,631. Carrier l2 rotates about a vertical axis a-a and is driven by a drive shaft I3 welded to an upper end plate 14 of the carrier at I5. This plate cooperates with a'bottom plate (not shown) for-supporting a plurality of hollow spindle-carrying bars l6 which are arranged vertically and are spaced circumferentially about the carrier. The upper plate I4 is provided with a plurality of bearings ll respec tively for upper end portions of the circumferentially spaced spindle-carrying bars It, and the lower plate (not shown) is provided with similar bearings for lower end sections of said bars.
Each carrier bar lfisupports a plurality of vertically spaced picker-spindles IB-having beveled gears I9 upon endsthereof projecting into theinterior of their bars. Gears I9 are driven by companion gears 2| constrained for rotation with an associated shaft 22, there being a shaft 22 in each of the carrier bars [6. The shafts 22 are piloted in ball bearing units 23 spaced axially thereof and carriedupon th carrier bars. All of shafts 22 are driven in the same direction by gears 24 upon their upper ends which mutually mesh with a large sun gear 25 which is rotated by a large tubular drive shaft 26 secured thereto by cap screws 21.
ball bearing unit 28. The bars l6, which are oscillatable within their'bearings as l 1, are controllable in the angularity of their oscillation by arms 29 respectively secured to their upper ends. These arms 29 are oscillated =by cam means (not shown) for causing the spindles 18 on their associated bars Hi to enter the crop plants perpendicularly to the rows during that cycle in the rotation of the carrier l2 when the spindles are pre-- sented to the crop row and likewise be maintained an inverted cylindrical recess 33- within the'lower;
. end of the carrier drive shaft I3 where it is ad- Concentricity is maintained between the sun gear 25 and the carrier l2 by a- 3 justably held in an axial direction by machine screws 34. A packing ring 35 within a circumferential groove of the receptacle cooperates with the side walls of the recess 33 in preventing leakage.
In the upper outer end portion of the receptacle 3| there are a plurality of radiating oil-conducting channels 36 which are disposed in respective registry with oil conducting passages or channels 31, each of which comprises a counterpart in the form of a radial hole 38 in the lower end portion of the carrier drive shaft l3, a radial bore 39 in the carrier end plate l4, and a tube 4| projecting from the outer end of its associated bore 39 into a respectively associated one of the hollow spindlecarrying bars l6. Each bar I6 and the shank of its associated control arm 29 is slotted as at 42 for accommodating the tube 4| therefor. The tubes 4| are open at their outer ends 43 for discharging into their associated spindle-carrying bars l6. Oil discharged from the end of each tube 4| falls onto the uppermost gear 2| which centrifugally throws part of this oil onto the inner periphery of its tube l6, whereby the oil descends upon said inner periphery and downwardly of the shaft 22 for lubricating all the gears 2| and I9 and for conduction axially of the spindles H; for lubricatimg their bearings 44.
Referring again to the receptacle 3 weir means is provided thereon for conducting the oil from the receptacle pocket 32 into the channels 36 from where it flows into the channels or passages 31 for lubricating the parts within and carried by spindle-carrying bars H in the above-described manner. In the present embodiment, this weir means comprises a plurality of weirs 45 respectively registering and communicating with the channels 36 and separated from one another by radially extending upstanding bosses 46.
Oil is fed into the device It] by a metering device (not shown) mounted upon a portion of the picking unit casing 41. Said metering device is connected with a threaded aperture 48 in the casing and feeds downwardly into the receptacle pocket 32 through a tube 49 which carries a flowregulating member 5| upon its lower end. The lower end of a bore 52 in the member 5| completes the communication between the tube 49 and the receptacle pocket. Said tube 49 and the member 5| are supported non-rotatably.
In the operation of the device, oil is permitted to drop downwardly through the tube 49 at a slow rate, for example, 15 to 25 drops per minute. This oil accumulates in the receptacle pocket 32 and eventually fills this pocket to its brim or to the weir means 45. Upon the oil rising to the height of the weir means, it will commence to flow thereover into the channels or passages 36 and thence through the passages 31 for lubricating the parts contained in and carried by the spindle carrier bars l6.
While the machine is in operation, the carrier l2 and therefore the receptacle 3| will be rotating about the axis a-a so that the centrifugal force upon the oil in the pocket will tend to overcome inequalities of the oil level within the pocket. Such inequalities may otherwise exist because of tossing and vibrational motion imparted to the device by the vehicular picking unit as it traverses an uneven or unlevel course. Also during operation of the machine as upon a hillside the axis a-a while then generally upright would not be exactly perpendicular. The centrifugal action of the rotating receptacle 3| also tends to overcome gravitational movement of the oil toward one side of the receptacle pocket during operating positions when the axis 0-0. is not strictly vertical.
The oil flow regulating member 5| also contributes to the maintenance of the upper surface of the oil in the pocket 32 in uniform relation to the weirs 45. The lower end of the member 5| is normally at a slightly lower elevation than that of the weirs and is therefore in an opposed contiguous relation with respect thereto within the upper portion of the oil body within the pocket 32. This member 5| thus serves to trammel swishing of the oil within the pocket, and since the member 5| is stationary while the side walls of the receptacle revolve thereabout, there is a constant redistribution of the oil circumferentially of the pocket to overcome any tendency for the oil to collect and build its upper surface to a higher elevation at any one section than at other sections. The just-described features of the device cooperate to maintain a uniform oil level, and uniform feeding of the oil over the weirs is supplemented by the internal cohesive Properties of the oil itself, so that all these features functioning collectively cause the device to distribute a small quantity of oil with adequate preciseness even when the machine upon which the device is run is traversing rough and/or unlevel terrain.
While in the present installation it is desirable for the distributing device III to cause equal minute quantities of oil to be delivered through the passages 31, it would be possible to incur unequal predetermined relative fixed amounts of oil through said passages. This may be done, for example, by forming some of the weirs 45 lower with respect to the others when it should be desired to increase the relative flow past these relatively lower weirs. Different flow rates through the weirs may also be obtained by forming the device with relatively wider weirs (circumferentially of the receptacle) at the points where greater flow is desired.
Having thus described the preferred form of my invention with the view of fully illustrating the same,
I claim:
1. In an oil distributing device, a structure rotatable about a vertical axis, said structure having an oil receiving pocket coaxial with said axis and a plurality of outlets through which the oil received by said pocket is to be discharged in equal quantities, said structure comprising weir means spaced radially from such axis and over which the oil spills from the pocket, and said weir means being disposed above said outlets and for directing the spilled oil thereinto.
