  • Field of Search..74/89.15, 527, 184/55 R may be moved axially between locked and unlocked positions. When in locked position, it may be secured by a seal wire to prevent tampering with the metering adjustment.

  • the present invention relates to improvements in a device of the type just described and particularly to the sight dome construction, its control or metering valve and other features associated therewith which may be briefly described by objects to provide:
  • a sight feed dome including a metering valve which cannot be accidentally removed and, when adjusted to a desired position, may be releasably locked against rotation;
  • a removable insert for the dome which, by suitable selection of a certain dimension thereof, the size of an oil drop delivered by same may be adjusted.
  • a novel filter screen of increased filter area which may also be readily removed for replacement or cleanmg.
  • FIG. 1 is a central vertical section through the subject of the invention
  • FIG. 2 is a section taken on line 22, FIG. 1;
  • FIG. 3 is a side elevation of a locking ring as viewed in the direction of arrow 3, FIGS. 1 and 2;
  • FIG. 4 is a section taken on line 44, FIG. 1, with parts in a different position.
  • dome 10 comprises an integral transparent body 12, 12a, a cylindrical insert 14, a needle valve 16, and a knob 18 ineluding a locking ring 20.
  • Body 12 is provided with equiangularly spaced channels 22, such as three, which deliver oil from annular Space 24 to chamber 26 from which it is fed at desired rate through annular metering aperture 28, surrounding frusto-conical needle tip 30.
  • Needlevalve 16 is provided with a flange 32 which threadedly engages body 12a for varying the size of metering aperture 28 and a stern 34'to the upper end of which is affixed knob 18 in any suitable manner, such as by press fit splines 36.
  • An O-ring39 prevents leakage past stem 34.
  • flange 32 prevents accidental removal of valve 16
  • the lower portion of knob 18 is provided with a plurality of angularly spaced locking legs 40, such as ten, which are provided with longitudinally extending splines 42 which may be sprung radially inwardly to engage corresponding splines 44 on body 12a, to thereby lock the knob against rotation.
  • Each leg is-provided with an arcuate camming surface 46,,best shown in FIG. 1, the camming surfaces of all of the legs lying on the surface of a cone.
  • Locking ring 20 is secured to knob 18 by a pair of keys 48 on the knob which engage corresponding keyways'50 in the locking ring.
  • the locking ring is thus affixed to knob 18 for conjoint rotation but may slide in an axial direction of the knob.
  • a seal wire (not shown) is disposed circumferentially in space 54 and its ends clamped together with a conventional lead seal. As will be apparent, the wire forms an abutment which prevents movement of the locking ring to its unlocked position.
  • Insert 14 snugly but removably fits within a cylindrical bore 55 in body 12, the upper end of which is provided with a cylindrical projection or spout 56, the diameter of which may be varied by substitution of inserts. Since oil flows at a low rate through the bleed orifice, it collects on the lower surface of spout 56 in the form of a generally spherical drop, the diameter of which may be controlledby selection of the diameter of spout 56.
  • Bore 55 is provided with a counterbore 58 at its lower end which forms an annular space 60 around insert 14.
  • An annular screen 62 is disposed within this space to filter out any foreign matter in the oil. As will be apparent, this provides considerable filter screen area which obviates the necessity for frequent cleaning or replacement of a filter screen.
  • the periphery of ring 20 is provided with frusto-conical projections 64 which forms non-slip abutments for pushing, pulling and rotating same with the fingers of an operator, these normally being the thumb, index and middle fingers.
  • the various parts of the device are preferably formed of plastic material, employing moulding techniques which minimize cost of manufacture, and body 12 and insert 14 should be transparent so that rate of flow may be observed from all peripheral points therearound. Oil drops falling from spout 56 are induced into the air stream, such as Inml') n-Ml.
  • the filter-screen is preferably formed of woven metal strands and the O ring "ispreferably formed ofoil resistant material, such as. synthetic rubber.Needle valve'16,'32,34 may be formed of metal,
  • valve stem may vary the rate of flow through the discharge orifice
  • said knob having resilient first locking means adapted to be urged radially-inwardly forv engaging second locking means spaced circumferentially on the dome body, whereby the knob may be locked at desired increments of its rotation
  • said knob including .a locking ring for rotating same, said locking ring being mounted for slidable movement in the axial direction of the valve stem, and
  • the construction and'arrangement being such that when the locking ring is moved axially in one direction, said camming surfaces cause said first locking means to engage said second locking means and lock the knob against rotation.
  • valve stem is provided with a threaded flange adapted to abut a shoulder on the dome body, when rotated to a predetermined position, to prevent removal of the stem from the come body.
  • a lubricator in accordance with claim 1 wherein said dome body is provided withan annular recess, at the end thereof remote from the knob, an annular filter disposed within said recess and a channel communicating said annular recess with the supply side of said valve.
  • a lubricator in accordance with claim 1 including a longitudinally extending cylindrical bore in the dome body, and a tubular insert disposed in said bore, said inserthaving a wall at one end thereof, said discharge orifice extending axially throu said wall.
  • said wall includes an annular surface surrounding said discharge orifice on which a drop of lubricant may form, prior to dropping therefrom, the diameter of said 7 annular surface being variable by selection of inserts,
  • a lubricator in accordance/with claim l wherein said locking ring may move axially between unlocked and locked positions, providing an annular space of variable width between one face of same and a face of a portion of the knob affixed to the stern, and a locking wire or the'like disposed circumferentially in said space for blocking axial movement of the ring toward un-' locked position.
  • a lubricator in accordance with claim 1 wherein the periphery of said ring is provided with angularly spaced isoceles trapezoidal recesses, facing in opposite directions, forming flat abutments' engagable -by the thumb, index and middle fingers of an operator for facilitating pushing and pulling the ring in opposite axial directions, and rotating same in opposite directions.
  • Means for axially positioning a rotatable first member threadedly connected to a fixed second member and for locking same in a desired axial position relative thereto, such as a rotatable needle valve relative to a fixed seat, to provide a variable orifice therebetween, comprising;
  • a knob member affixed to said first member for rotating same to a desired axial position
  • said second member having a plurality of circumferentially disposed and angularly spaced splines therein, extending parallel to the axis of rotation of the first member,
  • said first member having a plurality of angularly spaced resilient legs having second like splines
  • said second splines normally being out of engagement with said first splines but adapted to engage therewith upon radial inward movement of said l g a ring member, forming a part of said knob, rotatable therewith and axially movable relative thereto, and
