Fig. 4 is a side view of the dispenser shown Within the plates 5 and 8 I place apertures I3 in 2 applied to a paper bag or sack, with a of a configuration similar to a cross section of the portion cut away to more clearly show the concompartments The apertures in the plate 8 struction. a are in staggered relation to those in the plate 5.

Fig. 5 is a side view of a modified form of In the preferred embodiment illustrated in Fig. 55

1. I have shown two apertures I3 and I3a in the upper plate 5'and on opposite sides of the plate. In the lower plate 8, I haveshown two apertures IIb and I3c on opposite sides of the plate and at right angles to the opposing apertures in plate 5. In the embodiment shown in Fig. 1 there are eight compartments 6, and by placing the apertures in the plates as above indicated, the operation of the dispenser is as follows: The material in the container when it is inverted will f'lll the two compartments 6 under the apertures I 3 and I3a in the upper plate 5. The lower plate Il will form a. bottom for these two apertures. If the shaft Ill is now turned counterclockwise so the apertures will all move one compartment in that direction,

there will be no dispensing as yet, but the two compartments to the left, in counterclockwise direction, will be filled through the apertures I3 and I3a. If now the shaft III is again revolved in a counterclockwise direction, the apertures in the plate 8 will position themselves under the first two compartments filled, and will discharge them through the exhaust opening 3. The solid portion of the plate 5 will cover the compartments being discharged so that no more than the measured quantity of material may run through them. It is quite apparent that on each further movement of the shaft III in a counterclockwise direction, the apertures will progressively position themselves under following compartments and will successively discharge each compartment while at the same time filling at least two compartments which are not being discharged. I wish to particularly call attention to the fact that my dispenser cap at no time between the registering of any of the apertures with the compartments opens a passageway from the container straight through to the exhaust opening 3.

To facilitate the operation of my dispenser cap I provide a handle I5 keyed to the end of the shaft III and preferably urged against the edge 3a of the exhaust opening 3. I cut teeth I6 in the edge 3a of the exhaust opening 3 with sloping shoulders I 6a on one side and a. sharp shoulder Ib on the other side. This insures that the handle I5 will be revolved at all times in the same direction. It is of course apparent that either direction will be satisfactory but that the handle and thus the shaft III to progressively discharge must be always turned in the same direction.

The modification shown in Fig. 3 comprises a circular casing 2| and the spider walls I tapered to the hub as is clearly shown in the drawing. In this modification the upper plate 5 is similar to that described above but the lower plate 22 is conical in shape so as to contact the tapered edges of the spider I. In this instance I have ound that a coil spring 23 is more satisfactory t \an a leaf spring in urging the plate 22 against theiwall edgs. The aperture openings in both the plates 5 and 22 are similar to that described above.

I provide a cap 25 which fits over the exhaust port edge 3a when the dispenser is not in operation. This cap has a hinged portion 26 through which a circular wire 21 runs and which preferably is positioned in a groove 28 in the container casing itself. I provide a slot 29 in the lip 30 of my cover 25 to permit the handle end I 5a to roject. From the above it is apparent that th cap 25 may be turned in relation to the cont iner casing, so that the slot 29 may be so positi ned as to fit over the crank end I5a at any positio` on the discharge port 3. In some cases it may, be preferable to provide the cap 25 with a spring so I provide a series of collars for attaching mydispensing cap to different -forms of containers.

f All of the collars have an annular lip 30 which fits into the annular opening 2 of the dispenser cap. The other end of the collar may have an annular flange 3l, Fig. 2, for fitting over the ordinary coffee container 33. Fig. 3 illustrates my collar with a screw flange 34 for fitting over and screwing on the typical opening of a Mason jar 35.

Fig. 4 illustrates a special collar for use with a paper sack. This -comprises the collar itself with a flange 38 of a circumference similar to the circumference of the paper sack and over which the paper sack mouth may be placed. There is preferably a bead 36a on the edge of the flange 36 and a spring hoop or collar 31 with split ends 33 formed of resilient material which may be positioned over the paper bag mouth to hold it tightly against the flange 36. Fastened on the inside of my collar is a wire framework which may be worked down through the material, in the bag in order to keep the bag in an extended condition.

Fig. 5 illustrates a modification of the bag holder of Fig. 4, the only difference being that the wire cage l0 is attached to the resilient hoop 31 and positions itself on the outside of the bag instead of on the inside. This permits the bag to be set in an upright position no matter how deated.

While the modifications in Figs. 4 and 5 show collars having a frame for use with bags, it is also apparent that the type of frame I use is not a limitation of my invention but merely for the purpose of illustration since it is apparent that a cylinder of paper, metal or some relatively stifI material maybe used in place of the frame illustrated in Figs. 4 and 5.

It is of course to be understood that numerous diierent forms of my preferred form as described above, may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-
