Definitions

  • This invention relates to automatic liquid-analysis apparatus and more particularly to the sample-supply means for such apparatus, said sample-supply means comprising a stepwise movable turn-table carrying a series of cups or other containers for the liquid samples which are presented individually to an aspiration or other suitable takeoif device for transmission of the samples in succession to the analysis apparatus.
  • Another object is to provide for the automatic movement of the stirring device into and out of certain of the cups during the rest periods of the turn-table of the sample-supply means.
  • Another object is to eliminate or to reduce to a tolerable degree contamination of the sample liquids which might otherwise occur by reason of the use of the same stirrer for a series of different samples.
  • FIG. 1 is a top plan view of sample-supply means embodying the invention
  • FIG. 2 is a side view, partly in section on the line 22 of FIG. 1, showing the take-off means and the stirring means in operative positions and in retracted positions;
  • FIG. 3 is a. view on a large scale, partly in elevation and partly in section, on the line 3-3 of FIG. 2;
  • FIG. 4 is a top plan view of part of the sample-supply means, with parts broken away or omitted for clarification of the illustration; and 7 FIG. is a sectional view on the line 55 of FIG. 4.
  • the samplesupply means comprises a carrier, here shown as a turn-table 10 which is intermittently turned by suitable mechanism disposed within a housing 12, said mechanism being illustrated by FIGS. 4 and 5 and hereinafter more particularly described.
  • the turn-table cornprises a plate 16 which carries a series of removable cups 18 for the liquid samples, said cups being isposed laterally of each other in a circular row.
  • plate 16 is provided with a series of holes 20 and the cups have a peripheral shoulder 22 which. rests on the marginal edge of the plate around the opening through which the cup projects as shown by FIGS. 2 and 3.
  • the take-ofii' device 24 and the mixer 26 are mounted on the housing 12 in the position shown by FIG. 1 and comprise parts which are movable to and from the positions illustrated in full lines and in broken lines by FIG. 2 in timed relation to the step movement of the turntable so that during each rest period of the latter the take-off tube 28 of the take-oil device and one or more stirrer members 3t) are moved into and out of the cups when the latter are positioned at the station of said take-off device and at the station or stations of the mixer 26.
  • the mixer 26 comprises two stirrers 30, one for the cup which is positioned immediately before the take-oif position; and one for the cup which is positioned at the take-off position, as illustrated by PEG.
  • the stirrer provided for the cup at the take-off position is operable to stir the liquid while it is being withdrawn from the cup and thus maintain the liquid previously stirred by the other stirrer in well mixed condition and prevents settling of matter from. the liquid at the take-off position. This is dminable and sometimes necessary in the case of liquids which contain matter which would otherwise settle out in a very short time, but ordinarily the mixer need have only the stirrer for the cup next to the take-oft position.
  • the stirrer comprises a metal spindle 32 which fits within a polyethylene tube 34.
  • the lower end 36 of said tube extends a short distance below the lower end of the cornp'anion spindle and is flattened to provide a paddle-like element to improve the stirring action.
  • the opposite side walls of the tube at the flattened portion may be held together in flat condition by heat fusing them or in any other suitable Way.
  • the polyethylene tubes 34 are substantially non-wettable and hence do not carry sample liquid from one cup to another. The non-wettable property of polyethylene is thus valuable to the present invention.
  • Stirrers 30 are rotated by (a miniature electric motor 38 the shaft of which is connected to one of the spindles 32.
  • the second spindle is actuated by the gearing which comprises the driving gear 40, rotated by the motor, and the comp-anion driven gear 42"to which the second spindle is suitably secured for rotation thereby.
  • the gears are mounted for rotation between the cover plates 44 and 46 carried by the housing of motor 38.
  • the mixer 26 is preferably mounted for movement to and from operative and retracted positions as a unit with the movable part 48 of the take-off device 24.
  • Said part 48 is a tubular metal crook through which the takeoff tube 28 formed of polyethylene tubing extends for connection to the pump of the analysis apparatus whereby the sample liquid isaspirated from the cup at the take-oif position.
  • Said crook 48 is pivotally movable and is mounted for pivotal movement to and from the positions illustrated by FIG. 2, as described in US. Patent No.
  • V crook is fixed to a rock shaft 50 mounted in a bearing bracket 52 on the top of housing 1-2 laterally of the turntable.
  • the mixer 26 is fixed to said rock shatt 50 by clamping the mixer frame or bracket 54 to said shaft by a companion clamp 56.
  • a rod 58 tor actuatingthe shaft is fixed thereto andprojects into the housing 12 through an elongated opening 60 (-FIG.
  • rod 58 for actuation by the positioned in the path of rod 58 so that when the rock shaft 56 is turned to the ,position in which the take-01f tube 28 and the stirrer rod 32 are in the cup, motor 38 is operated, and when shaft 50 is turned in the opposite direction to withdraw tube 28 and the stirrer from the cup, rod 58 disengages contact member 64 which thereupon moves by its own spring action to open the switch and thereby interrupt the operation of the motor.
  • Any other equivalent switching device may be used, for example a mercury switch mounted on the bracket 54 to tilt with the latter so that the switch is closed when the mixer is in the sample cup and opened when the mixer is Withdrawn from the sample cup.
  • a Geneva gear 66 is mounted on a shaft 63 which is secured to a plate 70 of housing 12.
  • a pinion gear 72 is mounted for rotation on shaft 68 and Geneva gear 66 is secured to said pinion gear.
  • Gear 72 is in mesh with an intermediate gear 74 which is in mesh with a driven gear 76 and said gear 74 is secured to a drive shaft 78 to which the turntable 10 is secured for intermittent rotation.
  • the driver for Geneva gear 66 is constituted by a pin 80 which projects upwardly from a set of stacked gears 82 which is part of a speed change mechanism operated by ⁇ the lever 84 shown in FIG. 4.
  • An electric motor not shown, turns a gear 86 which meshes with one of the stacked gears 82, depending upon the vertical position of gear 86, as set by the operation of lever 84, to drive pin 80 which drives the Geneva gear 66 for intermittently rotating the turn-table.
  • a cam member 88 is pivotally mounted at 90, at one end thereof, and the free end of the cam member is interconneoted by the tension spring 92 with the lower end of a pin 94 which is secured to plate 70.
  • a wire link 96 interconnects the free end of cam member 88 and the lower end of rod 58.
  • cam member 88 When cam member 88 is in the retracted (broken line) position illustrated in FIG. 4, the take-cit tube 28 and the stirrer 32 are withdrawn from the cups.
  • Cam member 88 has an arcuate part 98, and with the stacked gears rotating counterclockwise, as viewed in FIG. 4, it will be seen that before pin 80 engages a slot in the Geneva gear 66 to rotate table 10, the pin will first strike the cam member, which is in the path of movement thereof, and pivot said cam member from the full to the broken line position thereof, with the pin riding along the arcuate portion 98 during the period that it remains engaged in a slot in said Geneva gear 66.
