r 7 Claims.

My invention, therefore, has fora first object the provision of a dispensing device comprising a valve element which is arranged and de- {signed to break up material which may become caked or packed and thereby permit accurate dis-' .pensing thereof under all conditions. Another Fobject resides in providing a valve element of the foregoing character which is designed for both 'i'axial and rotary movement to accomplish the foregoing result. A still further object lies in providing a dispensing device which is cheap to manufacture, simple in design and one which is adapted removably to support reservoirs or containers of materials to be dispensed whereby the assembly may easily be taken apart and thoroughly cleansed.

With these and other objects in view, my invention includes the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying draw ing in which- I Fig. 1 is an elevation view of the casing of my dispenser with the valve element removed;

Fig. 2 is a perspective view of the valve element;

Fig 3 is an elevation View of the valve;

Fig. 4 is a sectional elevation view of the dispenser casing with the valve element operatively mounted therein; and

Fig. 5 is a fragmentary,-sectional elevation view, somewhat similar to Fig. 4, showing the valve element in its lowered position.

Inasmuch as my dispenser is preferably formed as a base support for the container of material to be dispensed thereby, I have not illustrated the container itself and it is to be understood that my dispenser may comprise a reservoir into which materials may be deposited and protected fromlthe atmosphere as, for example, illustrated recess,

tion 5. Theelement 3 maybe interiorly. threaded as indicated at 6 to receive the threaded base of i a container as, for example, the threaded neck [of a Mason jar or the like within which the material to be dispensed is contained. The casing is provided witha-t'apered lug l adapted'to support the same upon .a suitable bracket (not shown) provided with 'a'complementary, tapered The valve element, indicated generally at'8 and as illustrated in perspective in Fig. 2, comprises an upper cylindrical portion 9 and a lower truncated cylindrical portion ID. A Web, ll is preferably cast integrally with the upper and lower portions 9 and i0 and serves to retain the same inispaced relationship, the portions 9 and it formingspaced closure elements for the tubular section 4 of the dispenser casing. The upper sur-- face E2 of the truncated portion it preferably lies in an oblique plane whereby it may'serve not only'to effect a closure'of the tubular element 4 at the lower or discharge end thereof but also servesas a spout to guide theflow ofmaterial in its discharge. The upper closure element-9 is provided with one or, preferably, a plurality of blade-like elements 13 whichextend upwardly therefrom and serve, as will be evident from an inspection of Fig. 4, to penetrate and agitate the material contained in the dispenser and above the valve in the manner hereinafter pointed out;

In order to breakup any caking or packing of the material by means of the blades 43, I have provided means for effecting an axial and rotary -movement of valve 8. In the embodiment illus'-'-,

trated, the tubular element 4 of the dispenser cas ing is provided with a helical slot M which serves through the medium of a pin or bolt l5 operatively to secure the valve element within the casing of the dispenser and atthe same time to guide the valve, when operated,.in an axial and rotary movement. In assembling, the valve element 8 casing and a tapped opening it with which the valve is provided is brought into registry with Bolt I5 is then screwed into the.

the slot l4. opening it and a washer ill and helical spring l8, disposed between the Washer and head of bolt I5, afford free but resiliently constrained opera,- tions of the valve: An operating handle I 9 is provided which, in the form illustrated, is seis inserted within the tubular element 4 of the The upper cylindrical portion 9 of the valve element may, in diameter, exceed the internal diameter of the tubular element 4 of the casing or the surface elements of the portion 9 may coincide with the elements of the truncated portion H! which, of course, is of a diameter affording a sliding fit within the tubular element 4. Either alternative construction may be employed due to the fact that the slot [4 limits the movement of valve 8 and is of a length whereby when the valve is moved downwardly the portion 9 effects a closure at the upper end of tubular element 4.

In order to prevent material from escaping through the slot 14 upon an actuation of the valve, the cylindrical surface of the valve 8 is continued adjacent the web H, as indicated at 22, so as to cover the slot M when the valve is lowered. The extended surface 22 need only extend to the edge 23 which is illustrated as helical in shape, in which event the edge 23 follows in registry with or slightly below the lower edge of the slot l4 upon a downward movement of the valve.

Inasmuch as there may be some tendency, of the material to cake beneath the upper closure element 9 of the valve 8 when, for example, the valve is permitted to remain in its upper position, I have provided the element 9 with depending lugs or projections 24 which, in the above instance, serve to agitate and break up such material.

In the normal operation of my device and assuming that the casing 2 is suitably mounted with a container of material supported thereon with the valve element 8 in the position illustrated in Fig. 5, the upper closure element 9 prevents discharge of material from the space thereabove.

Upon actuating the handle l9, the slot l4 guides the valve in an upward and rotary direction causing the blades 3 to agitate and break up any caked or packed particles of material. When bolt [5 lies at the upper end of slot l4, closure element ID of the valve effects a closure of the tubular element 4 near the bottom thereof and material may flow into and fill the space between the two closure elements 9 and ID, see Fig. fl. By actuating the handle IS in the reverse direction, the

"valve 8 is returned to its initial position as illustrated in Fig. 5 thereby discharging the material captured between the upper and lower closure elements and effecting a closure of the tubular element 4 at the top thereof. In operation, of course, the valve is operated quickly from one position to the other and therefore substantially equal volumes of material will be discharged therefrom upon each operation thereof, the closure elements being spaced preferably to discharge about one heaping tablespoonful.

The blades l3 may extend outwardly to pass in close proximity to the sides of the inverted, frusto-conical portion 5 and may be provided with broad surfaces to engage a considerable volume of the material to be dispensed. Obviously with the blades disposed in quadrature, a rotary movement of the valve through about will effect an agitation of substantially the entire volume of material lying above the valve and extending to a height determined by the upper limit of axial movement of the blade tips. 1

Obviously, I may provide any means whereby a rotary and an axial movement of the valve 8 may be effected within the casing of the dispenser to produce the results above pointed out. Furthermore, I may rely upon the closure element 9 to limit the downward movement of the valve 8 by forming the same to engage the sides of the inverted frusto-conical section 5 as should be evident from the foregoing description.

While I have described my invention in its preferred embodiments, it is to be understood that the words which I have used are words of description rather than of limitation. Hence, changes within the purview of the appended claims may be made without departing from the true scope and spirit of my invention in its broader aspects.
