' 5 Claims.' (C1. azi-117) My invention relates to dispensing caps tobe placed on containers lled withcoffee or relatively iine ground material and which dispenses the material from the container in a meshed 5 quadrant.

It is an object of' my invention to provide a dispensing cap which is relatively inexpensive to construct and which dispenses the contents vvwith the greatest of speed and ease. It is a further object of my invention to provide a dispensing Acap wherein the amount of material measured and dispensed may be Varied.-

' It is a further objectof my invention to provide a dispensing cap with all of the above features and in which the relative moving parts are all resilient in contact with each other to prohibit any leakage of the material being dispensed or jamming of the parts.

These and other objects of my invention which Will be set forth hereinafter or will be apparent to one skilled in the art upon reading this speciiication, I accomplish by that certain arrangement and construction of parts of which I shall now describe an exemplary embodiment. Reference is now made to the drawing which forms apart hereof, and in whichz.

45 Briefly in the practice of my invention, I

provide a dispensing cap comprisingtwo substantially opposed compartmentsv joined together by a blank web and closed at .the tonby a circular panel having an opening vregistrable with the compartments. i f The lower portions ofthe compartments are` formed by a separate casting which is telescopic on the upper part and is urged therefrom by a spring. There is a lower closure panel having an opening registrable with the bottom of the together. The spring urges the two telescopic castings of the compartments apart and at the Sametime forces them against the upper and lower panel, thus insuring a resilient pressure at all times between both panels and the cast ings against which they bear. An adjusting 5* screw limits the expansion of the telescoping axis and thus, by adjusting the same the depth` of the compartments may be varied. Referring to 4the drawing, I provide a casting I, which terminates in two substantially opposed/i6 compartments 2 which inmy exemplary embodiment are substantially in the form of a quadrant. These compartments 2 are joined together by blank webs whichv are also vin the"l form of quadrants. There is a hollow hub 4, hav- .1:18 ing an annularly opening 5, in its center and with its skirt Ei ruiming dow-n to the bottom. f the compartments 2 in the casting I.' i v Telescoped-on the annular portions. 'Iof the y casting I, I provide a second casting' having 20 an annular rim 8a which ydeiines by cross ,straps 9, four quadrants substantially the samesize and shape of the

quadrants

3 and 2. `TWO substantially opposed quadrants 2a are left opened whiley the other quadrants are closed by webs 3a. There are slots I0, in the skirt 6 of the hub 4 which permit the insertion'of the straps 9 of the lower casting 8. rThe annular rim Bw of the casting 8 is-substantially greater and telescopic aboutthe annular rim 'I of the casting I. There is a holo low hub. II centrally located amongst Athe quadrant of the casting 8, and of smaller diameter and telescopically. within the skirt 6 of the hub 4. The lower casting 8 is telescoped upinto the upper casting I, as is indicated in Figs. 3 andai@5 and in such a mannerl that the 'quadrants 2a form the lower part of theA compartmentsvv 2. Within the hub- I I and'seating against its innerface I2 is a spring I3. The other end ofvthis spring seats within the hub 4s upper face and thus tends to urge the castings I and 8 apart.,-

There is an upper closure plate I4 having a centralhub I5 which rides over the hubl 4 `and whichcloses the top of the. compartments y.2.

'Ihe plate I4 has anopening of quadrant widthi and registrable with the tops ofthe compartments 2. Integrally with the plate I4 and proj ecting downwardly through the hubI 4 is a square stem I6. w v I provide a lower closureplate I'I inthe formiigo of a circle,of a diameter substantially the same as the annular rim 8a.A Thereis an opening liliV j in the form of a quadrant in the plate I1 and I preferably provide a downwardly projecting, chute I9 surrounding a portion of the opening I8. 'Ihe lower plate I'I has an upwardly projecting stem 20 with a square cut-out portion 2| x running longitudinally therethrough. The squarev stem I6ts within the square hole 2I and thus ythe stems I6 and 2E) will rotate together and are 60v axially slidable within each other. The plate I'I is mounted on the bottom of the casting 8 as indicated in Figs. 3 and 4 with the stem 2U projecting up through the hub II and Within the coils of the spring I3. In assembly, the stems I6 and 20 are so positioned as to place the open- `ing I8 in the lower plate, opposed to and substantially from the opening, in the upper plate.

The bolt 22 pierces the plate II and is screwed into the end of the square stem I6. There is an adjusting nut 23 on the bolt 22 which varies the expanding limitations, to which the plates I'I and I4 may be moved.

In my exemplary embodiment, I have provided a groove 25 in the lower rim 8a of the casting 8 in which fits an upstanding rim 26 around the periphery of the plate Il. I also provide the plate Il with a radially projecting handle 2l and preferably with a thumbguard or stop 28.

. v When the upper casting I and the lower casting 8 are telescoped and the plates II and 4 vplaced in position with the spring I3, within the hubs II and I4, it is apparent that the spring I3 yurges the castings I and 8 apart by forcing them against the lower plate Il and the upper plate I4. This insures a resilient contact at all times between the plates and the castings.

.From the above construction, it is apparent lthat when the opening in the upper plate is registering with one compartment 2, the opening I8, in the lower plate is registered with the bottom of the substantially opposed compartment and the solid portions of the plate I4 covers the top of the compartment 2, which is over the opening I3. It is also apparent at this time, that in this position the solid portion of the plate Il covers the compartment 2 'which is opened at the top. Due to the fact that the connecting webs 3 'are at least as great in size as the size of` the compartments 2, the rotation of the plates I4 and II together will never provide at one time, a compartment 2 with an opening above and an opening below at the same time.

Inorder to prevent the material in the container riding around on the upper plate I4, I have provided a vane 29 which almost contacts the upper 4portion ofthe plate I6 and is terminated at itscenter with the other terminal held in position on the casting I by means of ngers 30. I also provide an upstanding rod 3l which rides around with the upper plate Id.

From the above description it is apparent that due to the telescoping feature of the castings I and 8, and inasmuch as these castings together dene the depth of the compartments 2 and hence their capacity, that the axial or telescoping movement of the two castings will vary the capacity of the compartments 2. I, therefore, provide a scale 3Il on the outside of the annular fportion'l of the casting I which indicate the relative movement of the two castings I and 8, and hence, the relative contents of, the compartments 2. l

It is, therefore, understood that different forms of my preferred form may be made without departing from the spirit of my invention.

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

1. A dispenser cap comprising at least two compartments of a given peripheral configuration and size, said compartments being spaced apart by a blank web atleast as large as the peripheral conguration of the compartments, an upper and lower closure for said compartments comprising plates, at least one opening in each plate of a peripheral configuration as great as that of the compartments, the opening in one plate being registered with one compartment while the opening in the other plate is registered with the other compartment and means for moving said plates together so that their openings will register with successive compartments, the depth of said compartments being adjustably variable.

2. A dispenser cap comprising two oppositely least as small as a quadrant and having a depth and being spaced apart by oppositely disposed substantially sectorial webs, an upper and lower closure for said compartments comprising circular plates mounted on and rotatable by a common shaft, an opening in each of said plates of a configuration registrable with said compartments,- the opening in one plate being oppositely disposed to the opening in the other plate, means for rotating said shaft and stops co-acting therewith `disposed substantially sectorial compartments at to the opening inthe other plate, means for rotating said shaft and stops co-acting therewith to position said plates so that the openings are in registry with said compartments, the depth of said compartments being adjustably variable, the opening in said lower plate having a chute depending therefrom.
