Nov. 18, 1952 s. J. LEVINE DEVICE FOR COUNTING AND DISPENSING PILLS Filed Oct. 18, 1950 INVENTOR SFIMUEL. J. LEVINE ATTORN -IL I... R L1 m\ H 00 M /Hm 600000000009 w/ C 000000000000 HM Patented Nov. 18, 195 2 UNITED STATES PATENT OFFICE DEVICE FOR COUNTING AND DISPENSING PILLS 7 Claims.

This invention relates to devices for use in countin and dispensin small body members, such as pills, for example, in the bottling of various type and kinds of drugs for sale. More particularly, the invention deals with a device having means for quickly varying the number of pills to be counted and dispensed so that the operation of bottling or packaging can be accomplished in a short period of time. Still more particularly, the invention deals with a device of the character described, wherein the balance or surplus of uncounted pills can be quickly and easily returned to a supply container.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a sectional view through a counter and dispenser made according to my invention, the section being substantially on the line |l of Fig. 2.

Fig. 2 is a plan view of the structure as seen in Fig. 1.

Fig. 3 is a view looking in the direction of the arrow 3 of Fig. 1, showing only part of the construction on an enlarged scale; and

Fig. 4 is a sectional detail view, showing the use of a shim plate for varying size of the pill to be counted.

In Figs. 1 and 2 of the drawings, I have shown at I!) a box or casing, comprising side walls II and I 2 and a back wall l3, these walls being grooved adjacent the upper end portions thereof, as indicated at M, to receive a table or platform I5. The table or platform l5 has a plurality of alined apertures l6 arranged in rows, twelve apertures being disposed in each row with the exception of one short row containing two apertures, so that a total of fifty pills can be counted and dispensed in a single operation.

The platform has, centrally of its forward edge, a downwardly extending dispensing trough I! which projects sufiiciently to facilitate arrangement of a bottle or container therebeneath, into which the uncounted pills or other members are adapted to be placed.

The box l0 includes, above the table or platform l5, front Wall portions [8 and these wall portions, where they join the side walls I I and 12, are rounded, as seen at l9.

Upper surfaces of the walls II and [2 have spaced notches or recesses 20, to receive outwardly extending members 2| on a partition element 22. The element 22 has rounded end portions 23 which in conjunction with the rounded corners l9, form, at all times, a surface facilitating free sweeping movement of pills or the like for dispensing through the trough H. The partition element can be placed in any position to expose one or more of the rows of apertures It or, if desired, all of the apertures, so that one to three, or four dozen pills, or a total of fifty pills, can be counted in a single operation, as later described.

Arranged below the table or platform l5 is a dispensing hopper 24, having a contracted discharge 25. Pivoted to the upper rear portion of the hopper 24, as at 26, is a ill or tablet supporting plate 21, which supports the pills or tablets, or other members, in the exposed apertures I6, until all of the exposed apertures are filled, after which, the plate 21 is lowered into the dotted line position, which will allow the pills or tablets to drop and pass out through the discharge 25 into a receiver bottle or receptacle 28.

The lower end of the hopper 24 has an outwardly extending apertured bearing 29, in which is slidably mounted a rod 30. The rod 30 supports, at its lower end, a block 3| having a curved recess 32 therein, suitable for reception of part of the upper edge of the bottle or receptable 28. The upper end of the rod 30 is coupled to a short end 33 of a lever 34, the lever being pivoted to the hopper, as seen at 35. The free end of the lever 34 is coupled with a link 36 which, in turn, is pivoted to the plate 21, as seen at 31; a spring 38 is fixed to the plate 15 and to the lever 34 and normally supports the plate 21 in raised operative position. It will be understood that the bottle or receptable 28 is held in the hand and placed in the recess 32 of the block 3| and then pushed upwardly to a position adjacent the discharge 25. In this operation, the lever 34 is actuated to move the plate 21 into its lowered position, as indicated in dot and dash lines in Fig. 1 of the drawing.

In Fig. 4 of the drawing, I have shown, on top of the platform or plate l5, a supplemental shim plate or platform 15, which will have apertures It, smaller in diameter than the apertures #6, thus pills, tablets or other members of smaller size can be counted and dispensed. In other words, if the apertures of the table member are of the largest size, then two or more shim plates or platforms can be utilized to adapt the one device to counting and dispensing pills of dilierent sizes. However, in many instances, individual devices will be utilized for the different sized pills, tablets or the like to be counted.

It will be understood that, after the partition element 22 has been adjusted to the position to expose the desired number of apertures in counting one dozen or more of the pills, or similar bodies to be counted, a large number of these bodies are quickly dumped into the space forwardly of the element 22 and are then moved around by hand over the exposed apertures until all apertures are filled, after which a sweep of the hand will replace the surplus pills or bodies into the receptacle held below the trough, as previously stated. Then the mechanism is tripped to dispense the counted pills into the receiving bottles or other receptacle as heretofore stated.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
