The present blender is in the form of a compact, selfcontained and inexpensive unit, which is readily adjustable to provide for absolute control over the primary blending mechanisms to be observed, as well as to permit investigation of of the effects on the blending mechanisms of internally induced agitations, liquidsolids contact and drying. Moreover, the present blender permits accurate control of the positioning of material within the blending container prior to blending and the removal of samples of the blended material without disturbing adjacent areas thereof.
More specifically, the blender of the present invention features an axially shallow drum-like blending container having one end cover or top removable to afford access to substantially the entire blending area. The blending container is supported by joining its closed end cover to a drive shaft, which is in turn tiltable to orient the axis of the blending container selectively in either a substantially horizontal blending position or vertical filling-sample extracting position. At least the removable end cover of the blending container and preferably the entire container is formed of a transparent material in order to pennit visual observation or photographic study of the various blending operations to be performed.
In a preferred form of the invention, an agitating or agitating-liquid dispersion head is supported for independent driven rotation within the blending container by a drive shaft mounted concentrically within the container drive shaft. In an alternative form of the invention, the effects of drying and/or gas contact in the blending operation may be observed by re-placing the agitating device with a gas-vacuum treating device contoured so as to introduce minimum turbulence within the material being blended.
By means of the present invention, there is provided a convenient experimental blender, which permits an observer to visually study all aspects of blending phenomena within a short period of time and with the use of only relatively small quantities of materials to be blended.
DRAWINGS The nature and mode of the present invention will now be more fully described in the following detailed description taken with the accompanying drawings wherein:
FIG. 1 is a front elevational view of the blender of the present invention;
FIG. 2 is a top plan view of the blender shown in FIG. 1;
FIG. 3 is a side elevational view of the blender shown in FIG.'l; and
FIGS. 4A-4C are sectional views taken generally along line 4--4 of FIG. 1 and showing alternative blending arrangements.
DETAILED DESCRIPTION A preferred form of the blender of the present invention is generally designated as 10 in FIGS. 1-3 and shown as including a support assembly 12, which serves to mount a blending container 14 and associated drive 16; an agitating device 18 and associated drive 20; and a control console 22. I
lapping leg portions of stand 24 and bracket 26 being pivotally connected by axially aligned pivot shafts 28 and 29. As will be apparent from viewing FIG. 3, bracket 26 may be manually rotated relative to stand 24 about a horizontal axis defined by pivot shafts 28 and 29 and be releasably, and frictionally locked in a desired position by operation of a knob 32, having a shaft, not shown, which is threadable into the stand and slid'eably received within an arcuate slot 34 provided in the bracket.
In its preferred form, agitating devicel8 includes a pair of plate portions and 82, which are clampingly secured together by bolt fastener devices 84, the latter, if desired, additionally serving to mount generally L- shaped agitating blades or fingers 86. Agitating device 18 may also be employed as a liquid dispersion head. To this end,- plates 80 and 82 cooperate to define a liquid reservoir or cavity 88, and suitable spacers, not shown, are arranged between abutting surfaces of the plates so as to define an annularly extending liquid discharge slot 90. As will be apparent, the amount of liquid discharged radially through slot 90 will depend primarily upon the width of the slot and the rotational speedofdevice 18, r v
Desired rotations may be imparted to device 18 by drive 20; which includes a hollow drive shaft 92, suitably afi'ixed to plate portion 82'and supported concentrically within container drive shaft 50 by sleeve 'bearing'94; a shaft mounted pulley 96; an electric motor 98 having a drive pulley 100; and a flexible drive belt 102 for drivingly connecting pulleys 96 and 100.
Y Motor 98 is, as best shown in FIG. 1, fixedly carried f Q {beneath connecting plate portion 26'.
j It will be understood that the direction of rotation of I device 18 and/or its speed of rotation relative to con- 'tainer 14 may be varied depending upon the blending experiment being performed. To this end, control console 22 is provided with knobs 104 and 106 for the purpose of adjustably controlling energization of motors 98 and 58, respectively.
Liquid to be dispersed within container 14 by operationtof device 18 may be fed through drive shaft 92.

The mounting of blendingcontainer 14- in this manner may be achieved by forming the forwardly facing surface of hub 66, such that it lies within a plane making an angle of 01/2 with the rotational axis drive shaft 50. While theconstructions illustrated in FIGS.

When employing this latter construction, a flexible tube, also not shown, would be attached to the outwardly extending 'end' of tube 104 in order to facilitate pivotal movements of bracket 26 relative to t d. 2 y
In the construction thus far described, material may be loaded into or unloaded from container 14 by rotating bracket 26 to position the container in its phantom line position shown in FIG. 3, and removing top 40. In this position, the rotationalaxes of container 14 and drive shaft 50 are in alignment and substantially vertically disposed. Since container 14 is axially shallow and the removal of top 40 completely exposes the full crosssection of the blending chamber, different materials to be blended may be accurately positioned within the chamber as desired. For example, materials may be placed in layers for the purpose of examining axial blending phenomena, that is, movement or migrations of materials axially of the blending chamber; and/or in different radial quadrants of the chamber for the purpose of examining the radial blending phenomena, that is, movements or migrations of materials radially of the shaft 50 for the purpose of varying the inclination of the axis of container 14 relative thereto. l
FIG. 4C shows a gas treating device 110, which may be employed in place of agitating device 18. Device 110 includes a pair of plate portions 112 and 114, which are clampingly secured together .by screw devices 116, and cooperate to form an open ended cavity 118. Cavity 118 may be closed by screen plate 120, which additionally serves to support a tube 122 arranged concentrically inwardly of device mounting shaft 124. In the arrangement shown, a treating gm or air may be introduced into container 14 via tube 122 and such gases and/or vapors subsequently exhausted through screen plate 120 and a passageway 126 defined by tube 122 and shaft 124. As will be apparent, shaft 124 may or may not be rotated depending upon the treating process to be .performed. Plate portions 112 and 114 are shown as being smoothly contoured in order to subject the material to be blended to minimum. perturbations. However, it will be understood that, if desired, material agitations may be maximized during a gas treating operation by employing agitating blades of the type discussed with reference to device 18 and providing for powered rotations of shafi 124.
If it is desired to observe blending phenomena without the use of devices 18 and 110, the latter may be removed by first removing pulley 96 and top 38 and thereafter pulling device 18 or 110 and itsshaft 92 or 124 outwardly through the blending jchamber. If
