MIXING DEVICE.

Specification of Letters Patent.

Patented' March 12, 1907.

Application filed April 3, 1906. Serial No. 309,606.

oughly mixing and intercommingling various.

materials and commoditiesdsuch, for instance, as teas, ground coffees, or different kinds of fiours or meals.

An object of the invention is to provide a means which is not only effective for the most complete and thorough mixing of the materials, but enables the accomplishment thereof without the necessity of the hands coming in contact with the material which is mixed.

As an example of the availability of the device made in accordance with this invention, it will be mentioned that in tea-stores it is a common practice for the clerk at the time 0l selling mixed teas to place a portion of two kinds of tea in the scoop or receiver of the weighing-scale and to then with the hands effect the mixing before the tea 1s packaged and delivered. This custom is in many cases obnoxious, owing to the uncleanliness of the hands of the salesman, and therefore by the use of the present mixer the tea of di`erent kinds placed and weighed in the scale is poured from the latter through my mixer, which also advantageously serves as a funnel for directing the material into a bag and is seen by the purchaser to come to him free from possible pollution.

The invention consists in a device having the parts in combination and arrangement hereinafter fully described, and set forth in the claims.

In the drawings, Figure l is a central vertical sectional view through the mixer. Fig. 2 is a plan view as seen below the section-line 2 2, Fig. l. Fig. 3 is a perspective view showing details of construction hereinafter particularly referred to, and Fig. 4 is a plan view of a form of blank from which one of the blades of the mixer is made.

Similar characters of reference indicate corresponding parts in all or the views.

In the drawings, Arepresents an axiallyvertical casing of cylindrical form having a flaring top portion a and a lower end delivery portion b, which is contracted or of decreased diameter.

This mixer, as shown, is supported on a frame B, which may practically be composed of wire, including opposite side u rights having in the upper portions thereo' the sockets or bearings b for trunnions d, provided at opposite sides of the casing A.

f f represent blades in series at different levels supported by and extended both downwardly and inwardly from the wall of the inclosing casing, and the blades of a given tier are inclined, as to their widths, reversing relatively to the cross-sectional inclination of the blades of the tier next therebelow. rIhe blades in their inward and downward exten sions are preferably non-radial relatively to the axis of the casing, but are extended inlines tangential to an imaginary circle somewhat outside of the casing-axis. 'Ihe manner of the inward, the downward, and the transversal extensions and inclinations of the blades and the reversal of the relations of those ol' one tier relatively to the other will be clearly understood from the drawings, it being stated,

, however, that in the present drawings for the purpose of clearness alesser number of blades are indicated than are actually usually used in the device.

C and D represent conical deectors, the one, C, being shown as located within the top portion of the casing, while the one D, has its location in the lower portion of the casing and below the lowest tier of deflector-blades. One of the conical deflect'ors is represented as made unitary with and rotatable in unison with a series of revoluble deflector-blades f2, I

mounted on and revoluble about an axiallyvertical shaft or bearing g. In the present instance the combined gate D and revoluble deflector-blades f2 are represented as located in the lower part of the mixer-casing, while the cone C is represented as immovably supported; but the relations of these parts C and D fl may be reversed, or a conical deflector combined with revoluble deflector-blades like those f2 may be mounted in the top portion of the casing in a similar manner to the partsy rotatably mounted in the lower portion ofthe ICO ing inclined as to their Widths reversely relatively to the cross-sectional inclination of the blades of the next series.

7. in a mixing device an axially-vertical cylindrical shell or casing open at top and bottoni, having removably fitted and engaged therewithin a plurality of separate and independently-movable ring-sections one above another, each ring-section supporting a series of blades inwardly extended therefrom, several of the blades being as to their widths inclined downwardly reversely relatively to the transverse inclination of other of the blades.

S. In a device of the character described, a cylindrical casing open at top and bottom, a plurality of' ring-sections itted and coniined at diilerent heights therewithin and each face of the ring-section, and inclined as to their widths, the inclinations of one set of the blades being reversed from those ofthe next set.
