Application. September 12, 1952, Serial No.

2 Claims. (Cl. 226-41) The present invention covers capsule filling such as drugs or sedatives.

It is an object of this invention to provide and wherein if groups 0I capsules of different sizes are desi-red to be simultaneously iiifled, a

F segregated capsulev re- Still another tion is to provide an improved device of this character with novel conveniently operable means for releasably locking or holding the vertically 2 Figure 2 is a side view, partly the device, Figure 3 device along is a vertical sectional View of the the line 3-3 of Fig. 1,

Figure 6 is of the movable plate shown in Fig. l, and

Figure 7 is a vertical sectional view taken on the line 'l`l of Fig. 6'.

In the embodiment of the invention illustrated in the drawings, Figs. 1 to 5 inclusive, the device spaced relationship to The bottom, or capsule ejector plate plate by means of the orner posts lil, of which Springs l5 yieldably Il upwardly against the heads f6 of The upper surface of plate l I is divided into a. plurality of sections by means disposed walls or partitions l 7. It will bev seen, Fig. l, that theser Walls with the other as to able number of apertures i@ therethrough.

The diametrical dimensions of the apertures in each section arey uniform one with the other but that they may diiier from those of each of the other sections, as shown in Figs. l through 5 of the drawings. However the apertures in the group of sections A, B, C, which sections din-er from eaehother as to number of apertures, are of the samesize. but they diiier in size from the apertures in the group of sections D, E and F, the apertures in these two groups ci sections dn er in size from the apertures in the group of sections G, H, and In each group the different It isobvious that each section might differV `from every other section as to diameter of apertures if such was desired. The-apertures oi each group or section are, of course, adapted to receivev and hold only thosev cup portions of capsules which in section, of

are adapted to fit into that groups apertures. These cup portions, designated I9, Fig. 3, are inserted in said apertures so that the openings thereto are flush with the floor of the capsule lling control plate li. Consequently the operator when lling capsules in a certain section or sections with selected medicated powders or granules may scrape along the floor of each section so as to evenly and adequately distribute the filler into the several cups of each section and the walls l1 enable him to confine his activities in the foregoing respects to the specific area within the boundaries of each sections walls. It will, therefore, be understood that with my sectionalized filler cup plate that the operator can utilize one or more sections for iilling all its cups with a particular filler while at time using one or more of the other sections for other ingredients without danger of mixing such ingredients.

Upon the filling of the cups aforesaid, the next step in the sequence of operations of my machine is to secure a closure cap 2i! to each of the aforesaid filled cups. rhe final step is to simultaneously eject all of the capsules from the plate. To expedite and eiiciently eiect these operations, provide a biiurcated operational control lever 2 l, each arm 2?; of which is pivoted intermediate its ends, by means of a pin 23 to a bracket Es, one each of which sides of the plate ii. Each of said arms, starting at a point approximately in the vicinity of the pivot pins 23 and extending to the cuter or free end ci each arm, is disposed in angular relationship with the inner portion of each arm and extends in a diagonal direction toward and adjacent to the opposite sides of ejector plate il). A slot 25 is provided adjacent the extreme end of each arm 22. Pins 2S, secured in the opposed sides of plate it, engage each of said slots to unitedly act as a ulcrum for the lever 2l. Thus it will be seen that when the lever 2 l, which is provided with the handle or knob 2l is pushed downwardly, as shown in Fig. 4, the pivoted connection to said lever and plate il will cause the latter to be lowered toward the capsule cup ejector pins 2B disposed in the plate lil, whereupon the lower ends of the cups i9, contacting the upper surfaces of pins 23 will force said cups upwardly in the plate l i a distance sucient to enable the closure caps i9 to be secured to said cups.

Upon completion of the capping operation aforesaid, further downward movement oi the lever 2l will cause the pins 28 to force the filled capsules to expelled position relative to the filler plate li.

In the actuation of the control lever iii, it is necessary only to latch or hold the plate li during the capping operation aforesaid. This is so because when plate il is in its full upward or capsule *filling position (Fig. 2) the springs i5 definitely maintain it in that position, and when the plate is manually urged by the lever 2l to its lowerrnost or capsule ejectmg position (Fig. it is necessary only to momentarily hold it in that position until the capsules have been cleared from the plate. Therefore, to effectively hold the plate in the central or capping position a spring, which may be in the form of a flexible metallic member 29, is secured at one end to the rearward portion of the stationary plate l@ and extends arcuately upward so that its intermediate portion abuts and presses against the inner face of the transverse portion of lever 2l adjacent the knob 21. An elongated slot 30 is provided in member the same 29 into which the inwardly extending pin portion 3l of knob 2l projects for releasable latching engagement therewith of the lever 2l during said capping operation.

In the modification of the invention illustrated in Figs. 6 and 7, I have shown a capsule lling control plate only and it is to be understood that this plate is adapted to be used with an ejector or base plate that is identical in every respect with the base plate lil shown in the heretofore described embodiment of the invention. Like its predecessor this modified capsule filling control plate 32 is positioned vertically above a base plate that is identical with the base plate ill. Plate 32, like plate is, is guided by posts 33 and is held in yielding engagement against the heads 341 of said posts by springs 35. Plate 32, however, is provided with a plurality of apertures 35 therethrough, the diametrical dimensions of which are uniformly of maximum width to receive therethrough capsules of the greatest capacity. For purposes of clarity in the further description of this modification this plate 32 shall be referred to as the main plate or seat portion of the plate as it is only a part of a composite plate subsequently to be described.

The ends and one side portion of said plate 32 are provided with an upstanding flange or rim 31 which is undercut in its inner face to provide a pair of opposed slideways or tracks 38 and 39 that extend transversely from the iront face thereof and terminate at the inner junctures of the side portion of the rim with the end portions thereof. Each of the aforesaid tracks is adapted to receive, for slidable engagement therein a ange is that is formed to project laterally from the side of a supplemental capsule filling control plate or slide 4i.

ri'his supplemental plate may have a plurality of apertures ll2 therethrough of uniform diameters but of less width than those of the seat plate 32; or, the supplemental slide plate di may be sectionalized in a manner similar to that heretofore described with respect to the sections conned by the walls l, and wherein the apertures of the different groups of each section not only vary in size from those of the adjacent sectional groups but again are of width less than those of the main plate. In Figs. 6 and 'i similar walls 53 are illustrated on the supplemental plate 4| for confining the apertures l2 therebetween.

Any one of a number of supplemental plates 39 may be employed with plate 32 in order that capsules of any required capacities may be filled. Thus a plate il having two or three sections the apertures l2 of each of which will accommodate capsule cups corresponding to the sizes of such apertures, another plate may have two, three or more sections the apertures of each of which are adapted to receive cups oi still different capacities, and so on. Consequently a complete set of supplemental plates for carrying out quantity production of capsule filling operations are provided to speedily and efiiciently fill any and all sizes of capsules, which are commercially available.

t will be understood that in the use of my supplemental plates il and their slidable insertion into the main plate 32, so as to form therewith a composite plate, each aperture in the supplemental plate lll will axially overlie an aperture disposed in the main plate 32. Thus whatever the diametrical dimensions are of the apertures in the supplemental plate they will always be ir positive axial alignment with the related apertures of the main plate, provided that the former control plate from movement relative to the plate is pushed all the Way back into the slideejector plate.
