  • FIG. l4 ARTICLE DISPENSING MAGAZINE AND A DISPENSER WITH REMOVABLE MAGAZINES I5 Sheets-Sheet 5 Filed May 4, 1965 137 I44 [42 a); in II' 1 /50 140 FIG. l4
  • This invention relates generally to dispenser devices, and more particularly to a device for dispensing discs which are used in testing the sensitivity of microorganisms to chemical agents.
  • Discs for such sensitivity tests are made of absorbent material, usually paper, and each disc is impregnated with a solution of a particular reagent. In earlier days, the reagent discs were used while still wet, but at the present time they are dried and may be stored for a long time before use.
  • the purpose of the sensitivity test is to determine which of several reagents kill or inhibit growth of microorganisms in the specimen being tested.
  • several discs, each impregnated with a different reagent are placed on a medium to which the test specimen has been applied. The medium and discs are incubated, and during incubation, reagents diffuse from the discs int-o zones of the medium surrounding the discs.
  • the activity of the reagents is determined by inspection. If a particular reagent is eilective to inhibit or stop growth of the microorganisms, there will be a clear zone around the disc containing that reagent. On the other hand, it a given reagent has little or no effect, the microorganisms will grow up to the edge of the disc.
  • Another object of the invention is to provide an improved device for dispensing reagent discs.
  • a further object of the invention is to provide a magazine for storing reagent discs from which a single disc may be easily dispensed.
  • Still another object of the invention is to provide a device for simultaneously dispensing reagent discs from several magazines, each of which is in itself a single-disc dispenser.
  • a further object of the invention is to provide a mutiple-disc dispenser which can be operated more easily than dispensers available previously.
  • FIG. 1 is a side elevation view of a multiple-disc dispenser in a raised position over a petri dish, portions of the dispenser being cut away to illustrate its internal construction.
  • FIG. 2 is a top plan view of the multiple-disc dispenser of FIG. 1.

  • FIG. 4 is a fragmentary plan View of the petri dish showing the positions of reagent discs which have been dispensed from the device of FIGS. 1-3.
  • FIG. 5 is an elevation view, similar to FIG. 1, showing by dashed lines the loading position of a magazine just before it is inserted in the dispenser, the dispenser being shown in its unlocked condition.
  • FIG. 6A is a fragmentary plan section along line 66 of FIG. 5 showing a pin and shelf arrangement by which a shaft of the dispenser is held in a raised position.
  • FIG. 6B is a fragmentary plan section showing the changed position of the pin after the shaft has been rotated to lock one or more magazines in place in the dispenser.
  • FIG. 7 is a bottom plan view of the unlocked dispensing device of FIG. 5 showing a locking plate and an actuating plate in their open positions.

  • FIG. 11 is an enlarged vertical section of the complete assembled magazine.
  • FIG. 12 is a bottom plan view of the magazine.
  • FIG. 13A is an elevation view of the magazine.
  • FIG. 13B shows the magazine with its lever in operated position, in the scale of FIG. 10.
  • FIG. 14 is a fragmentary view showing a protective cap covering the dispensing end of the magazine.
  • FIG. 15 is a top plan view of the cap.
  • FIG. 16 is a sectional view taken on the line 1616 of FIG. 15, but in the scale of FIGS. 11-13A.
  • the multiple-disc dispenser 20 includes a stand 22 which carries and supports several magazines 24, each containing a vertical stack of reagent discs 26. Magazines 24 are themselves singledisc dispensers, and each carries its own ejector lever 28. The levers of all magazines are depressed simultaneously by vertical movement of an actuating plate 30 carried on the lower end of a shaft 32 which can be moved axially downward by depressing a handle 34 mounted on the upper end of the shaft. Handle 34, shaft 32 and actuating plate 30 are shown in operated positions in FIG.
  • Stand 22 includes a generally tubular shell 23 which has an open lower end 36 adapted to receive the petri dish 38 therein.
  • the upper end of shell 23 is closed by a top wall 40.
  • Each magazine 24 extends through an aperture 44 in wall 40 and is suspended from wall 40 by a flange 42 on the magazine which rests on the top wall.
  • Each aperture 44 has a circular portion (see FIG. 7) to receive the tubular body of a magazine 24 and a slot-like extension 46 which accommodates lever 28.
  • Apertures 44 are arranged in a circle about the vertical axis of stand 22 and extensions 46 extend radially inwardly of the stand.
  • Stand 22 has a plurality of axially extending stops 48 which have a curved transverse section (FIG. 7). Each stop 48 is supported by wall 40 and backed up by a vertical rib 50 extending radially of shell 23 from stop 48 to the shell (FIG. 7). The bottom end 52 of rib 50 is re Switchd upwardly (FIGS. 1 and 3) relative to the bottom end 54 of stop 48 to make room for the side wall 56 of petri dish. 38 when the shell stands over the petri dish Z as in FIG. 3.
  • Ribs 58 each have an upwardly and inwardly tapering edge 53 which together provide a plurality (herein shown as a total of eight) of tapered edges 53 defining an internal conical form within shell 23 which upon engaging the upper edge 55 of petri dish 38 cams the dish to a centered position under stand 22, thereby assuring the centering of the magazines relative to the petri dish.
  • the inner vertical edges of each stop 48 are adapted to contact the side of the associated magazine to provide a backing for the magazines so that they will not move radially outward when actuating plate 30 is moved downward and forces lever 28 toward the magazine.
  • the lower end 54 of stop 48 projects downward slightly beyond the lower end 69 of magazine 24 so as to receive and guide each disc 26 when it is displaced laterally from the magazine as illustrated by disc 26a shown in dashed lines in FIG. 3.
  • Shaft 32 extends vertically through a hollow central hub 62 which projects upward from top wall 40 of stand 22.
  • Hub 62 has an axially extending internal keyway 64 which receives-a radially projecting pin 66 carried by shaft 32.
  • Pin 66 rides up and down in keyway 64 as shaft 32 is raised and depressed and holds the shaft against rotation.
  • the top of the keyway intersects a short horizontal keyway which forms a shelf 68 (FIGS. 5, 6A and 6B) inside hub 62.
  • Handle 34 is fastened by a screw 70 (FIG. 1) to the top end of shaft 32.
  • the handle has a tubular side wall 72 closed at its top end by a wall 74 from which a sleeve 76 projects axially downward and about the top end of the shaft.
  • Sleeve 76 and shaft 32 have matching fiat portions at 78 for preventing relative rotation between them.
  • a cover 79 closes a recess 96 at the top of handle 34 and may serve as a nameplate.
  • Both handle 34 and stand 22 may be made of molded plastic.
  • a coil spring 88 seats on a washer 81 supported on the top of hub 62 and the top end of spring 86 fits loosely in the annular space between wall 72 and sleeve 76 and abuts against end wall 74 of the handle.
  • Coil spring 80 is compressed when handle 34 is depressed as in FIG. 3, and returns the handle, shaft 32 and plate 30 upward when the handle is released.
  • a spiral coil spring 180 is disposed between and secured at its opposite ends to actuating plate 30 and a locking plate 84, respectively, plate 84 being located above the actuating plate.
  • Springs 88 and res both function as compression springs and are selected to counterbalance each other to hold shaft 32 in the rest position as shown in FIG. 1.
  • spring 80 is compressed further and spring 180 is relaxed and hence when the handle is released, spring 88 acts to return the handle and shaft upward to the rest position.
  • spring 100 is compressed flat and spring 80 is relaxed, and hence spring 100 biases pin 66 against shelf 68 to help retain handle 34 in the loading position.
  • spring 100 acts to return handle 34 and shaft 32 to the rest position of FIG. 1 when the handle is released.
  • Actuating plate 30 has a plurality of radially extending fingers 82 (FIG. 7) for depressing the ejector levers 28 of magazines 24.
  • Locking plate 84 also has a plurality of radially extending fingers 86 (FIGS. 7-9), the ends of which fit into slots 110 (FIG. 1) in magazines 24 to hold the magazines in place.
  • the central opening 80 in plate 84 has a fiat edge 92 (FIG. 9) abutting a fiat surface 94 on shaft 32 to prevent relative rotation between shaft 32 and plate 84 but allowing shaft 32 to move axially through opening 90.
  • Plate 84 is thus held angularly oriented relative to pin 66 such that the ends of fingers 86 are rotated into slots 110 when shaft 32 is rotated clockwise as viewed in FIG. 6B to bring pin 66 into alignment with vertical keyway 64.
  • Actuating plate 30 has a central opening with a square edge (FIG. 8) fitting on a square tip 97 at the bottom of shaft 32 (FIG. 1). Tip 97 may be cross slotted and pushed over to stake plate 30 to shaft 32. Plate 30 is thus also held angularly oriented such that its ends are always aligned with the ends of fingers 86.
  • actuating plate 30 is spaced slightly below locking plate 84.
  • actuating plate 38 is moved downward by shaft 32 into sliding engagement with ejector levers 28 and cams the same simultaneously laterally toward the tubular body of the associated magazines 24.
  • Each lever 28 has a bent-over conta-ctor tip 104 at its lower end which moves laterally toward the lower end 60 of magazine 24 while the ejector lever is moved by actuator plate 30.
  • Maga zine 24 is open at its bottom end except Where it is partially bridged by diametrically opposite retaining arms 185 and 106 (FIGS. 12 and 13).
  • each lever 28 bends each lever 28 and in doing so moves tip 104 between the spaced ends of arms 1% and 186 laterally across the lower end of the associated magazine to thereby displace the lowermost disc laterally out of each stack into the curved hollow of the associated stop 48, as illustrated by the disc 26a shown in broken lines in FIG. 3.
  • the end of each contactor tip follows a curving path to the left and upward as viewed in FIG. 3 which helps to insure that it will eject only the lowermost disc of the associated stack.
  • FIGS. 1 and 3 Although only one magazine is shown in detail in FIGS. 1 and 3, in the illustrated embodiment, two or more magazines may be placed in the stand (eight magazines labelled A through H are shown in FIG. 2), so that any number from one to eight discs may be dispensed simultaneously into the petri dish depending upon the number of magazines loaded in the stand. Three such discs A, H and G are shown in FIG. 4 after they have been disclaimedd.
  • FIGS. 5-8 The manner in which magazines are loaded into the stand is illustrated in FIGS. 5-8.
  • handle 34 To prepare the dispenser for loading, handle 34 is pulled upward as far as it will go and then rotated counterclockwise to its loading position wherein pin 66 is abutting the end wall of the horizontal keyway in projection 62 and is urged downwardly onto shelf 68 by the force of spring (see FIG.
  • handle 34 is then rotated clockwise to swing pir 1 66 from the position shown in FIG. 6A to its position in FIG. 6B, thus moving pin 66 into keyway 64.
  • a finger 86 on locking plate 84 enters slot 110 just below flange 42 of each magazine 24, thereby locking each magazine in place (FIG. 1).
  • This rotation also swings the corresponding finger 82 on actuating plate 30 into alignment with the corresponding lever 28 on each magazine 24, all of the slots 46 thereby being closed by fingers 82 as shown in FIG. 8.
  • spring 100 moves handle 34, shaft 32 and plate 30 downwardly to the rest position shown in FIG. 1.
  • the stand is then reliably secured in this locked condition due to the counterbalanced condition of springs 80 and 100 so that the stand may be picked up by handle 34 and even shaken violently or turned upside down without unlocking the magazines.
  • the magazine includes a guide which may be in the form of a tube 120 closed at its upper end by a plug 122 and open at its lower end 60.
  • a stack of discs 26 is slida'bly received in tube 120 and retained therein at one end of the stack by short retaining arms 105, 106 whose tips are axially spaced beyond the lower end 60 of the tube by a distance slightly greater than the thickness of one disc. The latter spacing is such that only the lowermost disc in the stack clears the lower end 60 of the tube (see FIG. 13).
  • Arms 105 and 106 extend downward from diametrically opposite sides of the tube end 60 and their tips extend radially of thetube toward each other but are spaced apart (FIG. 12) to permit tip 104 to pass therebetween.
  • the spaced inturned ends of arms 105 and 106 each have a tapered edge, these two tapered edges converging relative to one another in the direction of disc displacing movement of tip 104 to thereby guide tip 104 cent-rally across the disc dispensing opening should the tip not clear arms 105 and 106.
  • the ejector lever 28 is carried by the tube for movement in a plane radially of the tube and comprises a resiliently flexible actuating arm having a contactor tip 104 at its lower free end which is free to move.
  • the other end 124 of lever 28 is affixed to tube 120 and may be integral with the tube wall.
  • Lever 28 is shown in its actuated position in FIG. 13A and in its unactuated position in FIG. 13B.
  • the tube and ejector lever are advantageously made of plastic material such as Plexiglas.
  • the tube has a projection 102 located directly under lever 28 about midway of the length of the tube, and may be an integral projection on the outer surface of the tube.
  • Projection 102 serves to limit bending stress at the juncture of lever 28 with the wall of tube 120 to thereby prevent premature fatigue of the plastic material as when the lever is being manually actuated by direct application of finger pressure thereto.
  • lever 28 is graduated in thickness in a plane coincident with the lever and axis of tube (FIGS. 13A and 13B). Maximum thickness occurs at a point 29 about two thirds of the distance from end 124 to tip 104, the lever gradually diminishing in thickness toward both ends from point 29. This increased section 29 between the midpoint and tip 104 of the lever stilfens the lever and causes the bending of the lever to occur in its thin section directly below its juncture with tube 120.
  • Flange 42 encircling tube 120 is formed just above the upper end 124 of lever 28 and has the aforementioned lug 126 spaced slightly from the upper end of the lever to define therebetween the slot 110 for receiving a finger of the locking plate 84.
  • the magazine as shown in actual size in FIG. 13A will hold a stack of about fifty reagent discs.
  • the stack is urged axially against retaining arms 105, 106 by a weight 130 (FIG. 11) biased by a compression coil spring 132 extending between weight 130 and plug 122.
  • the force exerted by spring 132 decreases as discs are dispensed, but when magazine 24 is in a vertical dispensing position with open end 60 at the bottom, weight 130 provides an increment of constant bias on the discs.
  • Spring 132 urges the discs against retaining arms 105 and 106 keeping them positioned there even when the magazine is inverted.
  • a label 134 (FIGS.
  • 10 and 13 may be afi'ixed to the tube on which may be inscribed the name of the reagent imp-regnated in the discs.
  • Attached to plug 122 is another label 136 on which is inscribed the same code letter, symbol or color as that used on the discs.
  • the illustrated embodiment of the magazine has a cap (FIGS. 14, 15 and 16) which fits over the dispensing end 60 of tube 120 to protect the discs from contamination and also to protect tip 104 of lever 28.
  • Cap 135 has a hollow cylindrical wall 137, a bottom wall 138, a lateral extension 140 and two ribs 142 spaced apart to receive contactor tip 104 between them. Thus, ribs 142 and extension 140 partially enclose contactor tip 104.
  • Bottom Wall 138 has two recesses 143 and 144 which receive re taining arms 105 and 106 when the lower end 60 of magazine 24 is seated on the diametrically opposite shoulders and 152 formed inside cap 135 (FIGS. 15 and 16).
  • the top surface 146 of bottom wall 138 is flush with the inner surface 148 (FIG. 11) of the retaining arms when the cap is in place and provides a platform which holds the discs level when they are being loaded.
