An object of j the present invention is to make a simple and effective devic whichmay be forced into a substance and eject anartiole i into the aperture tormedbythis process.

Referring to the drawings in detail, ajconstroke, with a capsule in the act of being distainer A comprises a holloiv, cylindrical shell with abottom member lfi'xedly secured'thereto end-having a'remov'able coverifi. The cylindrical container A is-fa'stened to a Wall as by means of wall hrac kets'iland l. A feed disk 51 is mounted to he rotatable "Within the lower endof the container and is provided with a recess6 therein of a slze .to receive one yoke-B comprises inet'al strips ll-and 12 which areifixedlv'secured.to opposite sides of ,a. ?ho1iow plunger -These strips ma be aflixedto the plunger aslhy brazing.

A stud 17 is mounted in the center of the hinged strip let and a coil spring 18 is mounted with the upper end thereof surrounding the stud 17, the lower end of said spring resting upon the top 2 of the container to normally force the yoke B upwardly with respect to the container. The lower end of the plunger 13 is beveled at both sides to bring the sides of the plunger 13 to a point 19 at the lower end. Spring metal strips 20 and 20 are mounted one on each side of the plunger 13 to normally close the lower end of the plunger 13 to provide a pointed wedge-shaped nose over the end of said plunger. Connected to the lower face of the bottom 1 of the container and opening into the interior of the container is a tube 21 upon which the plunger 13 is freely slidable. A helical feedway 22 is provided within the container A extending upwardly approximately one complete revolution above the disk 5, the helical feedway being of a depth to receive one layer of capsules so as to feed them down to the'discharge opening in regular succession. An ejector 23 is connected to the upper surface of the disk 5, as best shown in Figure 8, and extends slightly above the upper end of the helical feedway 22 so that upon each operation of the disk 5 the capsules 7 resting above the helical feedway 22 will be ejected sufficiently to prevent two capsules wedging in the pening 6 of the feedway, which might interfere with the spring feeding of the articles to the helical feedway.

The operation of the device is as follows:

The container A is securely connected to the wall by means of brackets 3 and 4: which are screwed to the wall by screws not shown. The device is preferably placed above a shelf, also not shown, the shelf being spaced downwardly from the lower end of the plunger when in a normal position, to permit inserting a carton of oleomargarine beneath the plunger and leave a suflicient distance between the carton and the lower end of the plunger when in the position shown in Figure 5 to permit the ends of the spring metal points to close against the sides of the plunger before the plunger enters the carton of oleomargarine. The yoke latch 16 may then be opened, as shown in Figure 7, and the top 2 of the container may be r-emovedand a quantity of oleomargarine coloring capsules inserted in the container A. Upon placing a carton of oleomargarine beneath the device and forcing it downwardly to the position shown in Figure 2, the plunger penetrates the carton and forces a hole therein. The disk 5 is normally positioned with the opening 6 in the disk in register with the tube 21. Upon an operative movement of" the device which Figure 1, in which position one oleomargarine coloring capsule drops into the opening in the disk. This turning movement is, of course, effected by the twisted metal strip 10 lying in the opening in the yoke member 12. Upon the upward stroke of the yoke, the

disk is rotated in a reverse direction and,

upon the completion of the upward stroke, the opening (5 in the disk is brought into register with the tube 21, the coloring capsule then dropping through the tube and into the opening in the carton of oleomargarine. In a normal position the strips 20 and 20 are held apart by the inner tube 21 which projects downwardly beneath the lower end of the plunger 13, and, since the lowerend of the tube 21 is not beveled, as is the lower end of the plunger 13, the plates 20 and 20 are thus forced apart and permit the capsule to drop through.

Iclaim:

A dispensing device, comprising a .container having a discharge opening therein, feed means positioned to successively receive articles from said container and feed them into said discharge opening, a slidable plunger mounted beneath said discharge opening, said plunger having an aperture therethrough to permit articles discharged through said discharge opening to pass through said plunger, a shield normally covering the nose of said plunger, means 'operatively connecting said plunger and said feed means to actuate said. feed means upon a slidable movementof said plunger, and means positioned toengage said shield means upon a retractive movement of said plunger to uncover the nose of said plunger to permit an article to drop through said plunger.

2. A dispensing device, comprising a plunger having an, aperture therethrough, a

shield normally covering the nose of said plunger and means positioned to engage said shield upon a retractivemovement of said plunger to uncover the nose of said plunger to permit an article positioned therein to drop through said plunger.

3. A dispensing device, comprising a slidable plunger having. an aperture therethrough, feed means positioned to successively feed'articles'into said plunger, ashield normally covering the nose of said plunger, means operatively connecting said'plunger and said feed .means" to actuate said feed means upon aslidable "movement of said plunger, and means positionedto engage said shield'means upon a retractive movement of slidable plunger mounted beneath'saidopening, said plunger having, an opening therethrough to permit articles discharged through said discharge opening to pass through said plunger, a shield normally covering the nose of said plunger feed means mounted in said container to successively receive articles from said container and feed l them into said discharge opening, means operatively connecting said plunger and said feed means to actuate said feed means upon a slidable movement of said plunger; and means positioned to engage said shield means upon a retractive movement of said plunger toseparate said shield means to permit an article to drop through said plunger.
